Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to a bolted telescopic rod-type defense spray apparatus, and more particularly to a defense spray apparatus in which at least two sections may be pushed to each other to spray contents of an irritant gas can and may be positioned relative to each other to be locked into a function application having a rod-type member. 
         [0003]    2. Related Art 
         [0004]    A conventional umbrella or staff is easy to carry and can be used for defense; however, in a sudden strike of an armed villain, during a fierce fight, it is still possible that the villain causes death or injuries with a strike by using a bladed weapon. 
         [0005]    In addition, a conventional device such as a gas pistol and a self-defense spray device can be used to spurt high-pressure self-defense spray at a villain at a long distance greater than 3 meters to 4 meters before the villain approaches; however, for a function or a dosage of the device, an irritant gas or liquid can only be spurted at the face of the villain for a very few seconds to take away the vision of the villain, and if the villain closes the eyes and covers the mouth and nose and keeps slashing wildly with a weapon, the gas pistol and the self-defense spray are basically useless to stop the villain. Moreover, for the purpose of portability, a self-defense spray can is generally small and has a small volume, and a dosage of an irritant gas in the self-defense spray can support only a limited quantity of times of spurting. When the self-defense spray can is emptied after several times of spurting, if a danger still exists, an article such as an umbrella needs to be used for defense to resist an attack. 
       SUMMARY 
       [0006]    An objective of the present invention is to provide a bolted telescopic rod-type defense spray apparatus. In the bolted telescopic rod-type defense spray apparatus, two sectioned tube pieces and a spring pin component and a push joint component that are between the two tube pieces are applied to lock and unlock a relative position relationship between the two tube pieces, so that the defense spray apparatus has composite functions of a rod-piece additional function of a locking configuration of relative positions of the two tube pieces and a press-lever spray irritant gas can of an unlocking configuration of the relative positions of the two tube pieces. 
         [0007]    To achieve the foregoing objective, the present invention provides a bolted telescopic rod-type defense spray apparatus, comprising: a first tube body, having a head-end portion and a tail-end portion, the head-end portion having a receiving chamber, having a relatively large diameter, of an intra-tube space, an opening being provided on an end surface of the receiving chamber, a neck-portion structure being provided in the intra-tube space, a first pinhole being formed on a surface of the tube body between the neck-portion structure and the tail-end portion; a cap, covering the opening of the receiving chamber, a recessed seat being provided at a center of a surface, facing the receiving chamber, of the cap, a through hole being provided at a center of the recessed seat, a press-ring portion of an irritant gas can corresponding to the recessed seat, and an output tube being aligned with the through hole; a compression elastic piece, disposed and kept between the recessed seat and the irritant gas can; a second tube body, a top rod structure being disposed at a head end of the second tube body, a sheath structure being disposed at a tail end of the second tube body, a hole being provided on an end surface of the sheath structure, a second pinhole being provided at a body portion of the second tube body, and the second tube body being partially placed inside the first tube body; an anti-extraction element, fixed on a surface of the second tube body, and stopped at the neck-portion structure; a spring pin component, placed inside the second tube body, comprising a shell body having a recessed seat and a slot, an insertion pin placed at the recessed seat, and a compression elastic body placed between the recessed seat and the insertion pin, the insertion pin being axially aligned with the second pinhole, and a body portion of the insertion pin having a groove; and a push joint component, placed inside the second tube body, and having a fingering element, a hook rod, a pulling rod switch, and a pulling rod switch locking structure, the fingering element having a pivotal hole, a tail hole, and a fingering rod, the fingering rod being inserted in the groove of the body portion of the insertion pin, the fingering element being pivotally disposed in the recessed seat and the slot by using the pivotal hole, the pulling rod switch sequentially having a switch button, a shaft-neck portion and a shaft-tail portion, the switch button passing through the hole on the end surface of the sheath structure via the shaft-neck portion and being exposed from the sheath structure, a joint being provided on an end surface of the shaft-tail portion, a hook portion being formed at an end of the hook rod, the hook portion being hooked in the tail hole of the fingering element, a flange portion being formed at the other end of the hook rod and entering the joint, and the pulling rod switch locking structure being disposed between the end surface of the sheath structure and the pulling rod switch, so that after the pulling rod switch is extracted, the pulling rod switch may be kept at an extracted position. In addition, the pulling rod switch is extracted outward, so that an external thread and a threaded hole are engaged with each other. The switch button is rotated, so that the insertion pin is completely extracted from the first pinhole and the second pinhole to release a locking state between the first tube body and the second tube body, the sheath structure of the second tube body is held and pushed toward the first tube body, and the top rod structure may push a bottom portion behind the irritant gas can, to press the press-ring portion to spray contents. 
         [0008]    An advantage of the present invention lies in: In the present invention, a self-defense spray can and a rod-type umbrella or staff are combined, so that an irritant gas may be sprayed first and a rod-type object such as the umbrella and the staff may then be used to resist an attack of a villain, thereby improving an effect of safety protection. In addition, during walking in a mountain region or an uninhabited region, when there is a villain, a stray dog or an animal that attacks people, in a case of a headwind, if self-defense pepper spray is sprayed immediately, the spray may affect the one who sprays, so that for the rod-type structure of the umbrella of the present invention, the umbrella may be used first for defense against an attack of the villain or to drive away the animal that attacks people, and at a position of a tailwind, an irritant gas can be used to spray an irritant gas at the villain or the animal that attacks people, so that a double protection effect is achieved. Moreover, in the present invention, when a rod-type object is formed, the rod-type object itself also has a function of defense. For example, a rod piece such as a stick and an umbrella rod is used for strikes, and an extended cloth confuses the sight of the villain or the animal that attacks people or blocks a dangerous liquid sprayed by the villains. Therefore, an advanced apparatus that combines various defense functions is implemented.

     DETAILED DESCRIPTION 
       [0022]    The embodiments of the present invention are described below in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic views, and a basic structure of the present invention is described in a schematic manner. Therefore, only elements related to the present invention are labeled in the accompanying drawings, and the shown elements are not drawn according to quantities, shapes, sizes, proportions, and the like during implementation. Specifications and sizes during actual implementation of the elements are actually an optional design, and the layout and forms of the elements may be more complex. 
         [0023]    First, please refer to  FIG. 1  and  FIG. 2 . A bolted telescopic rod-type defense spray apparatus  1  in this embodiment is a two sectioned defense rod when a relative and axial movement of a telescopic rod is unlocked (if a tube body of the bolted telescopic rod-type defense spray apparatus  1  is shortened, the bolted telescopic rod-type defense spray apparatus  1  is a portable defense short stick). After the telescopic rod is unlocked, to spray contents A 3  of an irritant gas can A disposed inside the apparatus, a protruding output tube A 1  is provided at a top portion of the irritant gas can A, a press-ring portion A 2  is provided at a periphery of the output tube A 1 , and the press-ring portion A 2  may be subject to an external force of pressing to axially spray the contents A 3  from the output tube A 1 . 
         [0024]    The defense spray apparatus  1  includes: a first tube body  10 , a cap  20 , a compression elastic piece  30 , a second tube body  40 , an anti-extraction element  50 , a spring pin component  60 , and a push joint component  70 , The first tube body  10  has a head-end portion  11  and a tail-end portion  12  away from the head-end portion  11 . The head-end portion  11  has a receiving chamber  111 , having a relatively large diameter, formed of an intra-tube space. An opening  112  is provided on an end surface of the receiving chamber  111  and is used to provide a position where the irritant gas can A is placed and received in the receiving chamber  111 . A neck-portion structure  122  is provided in the intra-tube space, The neck-portion structure  122  may be an inward turning surface  1222  of a small inner diameter space  1221  whose diameter is less than the diameter of the intra-tube space, so that when a runner  85  and a runner locking structure  88  pass through, an insertion pin  613  is not touched, and the insertion pin  613  can be retracted into the second tube body  40 , to achieve unlocking. A first pinhole  13  is formed on a surface of the tube body between the neck-portion structure  112  and the tail-end portion  12 , and the first pinhole  13  is connected to the intra-tube space. The cap  20  tightly covers the opening  112  of the receiving chamber  111  (specifically, the cap  20  covers the opening  112  of the receiving chamber  111  in many manners; in practice, an external thread may be disposed on an outer side of an end surface of the opening  112 , a corresponding inner thread is disposed on an inner edge of the cap  20 , the cap  20  then covers the opening  112  in a threaded manner, or an L groove is provided on the outer side of the end surface of the opening  112 , a corresponding convex end is disposed on the inner edge of the cap  20 , the cap  20  is then pressed and rotated by a rotating angle to clamp the convex end in the L groove, to cover the opening  112 ), so as to close the receiving chamber  111 . A recessed seat  21  is provided at a center of a surface, facing the receiving chamber  111 , of the cap  20 . A through hole  211  is provided at a center of the recessed seat  21 , the press-ring portion A 2  of the irritant gas can A corresponds to the recessed seat  21 , and the output tube Al is aligned with the through hole  211 . The compression elastic piece  30  is disposed and kept between the recessed seat  21  and a can body top portion A 4  of the irritant gas can A, and because of an elastic force of extension of the compression elastic piece  30 , it may be avoided that after an umbrella is used in a rainy day, during an action of shaking off rainwater, the press-ring portion A 2  is shaken, a centrifugal force is generated in the first tube body  10 , and the recessed seat  21  is pressed accidentally to trigger spraying of the irritant gas can A. The second tube body  40  has a head end  41  and a tail end  42  opposite the head end  41 , where a hole  4111  is provided on an end surface of the head end  41 . A top rod structure  412  is disposed on the end surface of the head end  41 . A sheath structure  421  is disposed at the tail end  42 , a hole  42111  is provided on an end surface  4211  of the sheath structure  421 , a second pinhole  43  corresponding to the first pinhole  13  is disposed at a body portion of the second tube body  40 , the second tube body  40  is partially placed in the intra-tube space of the first tube body  10 , and when the second pinhole  43  is aligned with the first pinhole  13 , the body portion to the tail end  42  of the second tube body  40  are exposed from the tail-end portion  12  of the first tube body  10 . The anti-extraction element  50  has a stopping surface  51 , the stopping surface  51  has an inner diameter  511 , the inner diameter  511  is over a surface of the second tube body  40  and is fixedly connected thereto. The stopping surface  51  is in a direction opposite the head-end portion  11  of the first tube body  10 , and the stopping surface  51  faces and is stopped at the neck-portion structure  122 . The spring pin component  60  is placed inside the second tube body  40 , the spring pin component  60  includes a shell body  61 , the shell body  61  has a recessed seat  611 , a slot  612  connected to a space of the recessed seat  611 , the insertion pin  613  placed inside the recessed seat  611 , and a compression elastic body  614  placed between a bottom surface of the recessed seat  611  and a bottom surface, facing the recessed seat  611 , of the insertion pin  613 . The insertion pin  613  is axially aligned with the second pinhole  43 , and a groove  6131  is provided at a body portion of the insertion pin  613 . The push joint component  70  is placed inside the second tube body  40 . The push joint component  70  has a fingering element  71 , a hook rod  72 , a pulling rod switch  73 , and a pulling rod switch locking structure  74 . The fingering element  71  has a pivotal hole  711  and a tail hole  712  and a fingering rod  713  that are separately located on two sides of the pivotal hole  711 . The fingering rod  713  is inserted in the groove  6131  of the body portion of the insertion pin  613 . The fingering element  71  is pivotally disposed in the slot  612  of the recessed seat  611  by using the pivotal hole  711 , so that the fingering element  71  uses the pivotal hole  711  as an axial center, and inside the recessed seat  611 , the fingering rod  713  drives the insertion pin  613  to swing back and fro toward the inside of the recessed seat  611 . The pulling rod switch  73  sequentially has a switch button  731 , a shaft-neck portion  732 , a shaft-tail portion  733 , and a compression spring  734 . The switch button  731  passes through the hole  42111  on the end surface  4211  of the sheath structure  421  via the shaft-neck portion  732  and is then exposed from the sheath structure  421 . A joint  7331  is provided on an end surface of the shaft-tail portion  733 . The compression spring  734  is sleeved over the shaft-neck portion  732 , and two ends of the compression spring  734  is kept between the shaft-tail portion  733  and an inner side of the end surface  4211  of the sheath structure  421 . A hook portion  721  is formed at an end of the hook rod  72 , the hook portion  721  is hooked at the tail hole  712  of the fingering element  71 , and a flange portion  722  is formed at the other end of the hook rod  72  and is locked in the joint  7331  (the flange portion  722  is received inside the joint  7331 , and is freely rotatable relative to the joint  7331 , as shown in  FIG. 6  and  FIG. 8 ). A pulling rod switch locking structure  74 ′ is disposed between the end surface  4211  of the sheath structure  421  and the pulling rod switch  73 , so that after the pulling rod switch  73  is extracted in a direction of an outer side of the end surface  4211  of the sheath structure  421 , the pulling rod switch  73  may be kept at an extracted position of the pulling rod switch; at this time, the compression spring  734  is in a state of being pressed. After the pulling rod switch locking structure  74 ′ releases the pulling rod switch  73 , the pulling rod switch  73  is pulled back to an original position by means of an elastic resilience of the compression spring  734 . 
         [0025]    Continue to refer to  FIG. 3 ,  FIG. 4 , and  FIG. 5  for assistance, by means of the foregoing structure, when a user wants to use a function of defense spray and releases the first tube body  10  and the second tube body  40  that are locked to each other, the switch button  731  is extracted in a direction of the outer side of the end surface  4211  of the tail end  42  of the second tube body  40  and then rotated to enable an external thread  741  and a threaded hole  42112  to be engaged with each other, so as to enable the pulling rod switch  73  to pull the hook rod  72 . The hook rod  72  pulls down the fingering element  71 . The fingering element  71  can use the principle of levers to enable the fingering rod  713  to push down the insertion pin  613 , so that the insertion pin  613  inserted in the groove  6131  enters the second tube body  40  to be completely extracted from the first pinhole  13  and the second pinhole  43 , so as to release a locking state between the first tube body  10  and the second tube body  40 . The first tube body  10  and the second tube body  40  are then separately held with two hands, and the sheath structure  421  of the second tube body  40  is pushed toward the first tube body  10 , so that the top rod structure  412  can push the irritant gas can A to press the press-ring portion A 2  to spray the contents A 3 . 
         [0026]    As shown in  FIG. 2  and  FIG. 10 , in an embodiment, to avoid axial relative rotation between the first tube body  10  and the second tube body  40  to make it difficult to align the first pinhole  13  and the second pinhole  43 , a corresponding anti-rotation structure ( 44 ,  14 ) is separately disposed on a tube body surface and a tube body inner surface of an area, inserted in the intra-tube space of the first tube body  10 , of the second tube body  40  (in practice, non-circular section shapes are formed on the surfaces of the corresponding tube bodies in which one is sleeved over another, for example, a plane or the like is correspondingly disposed, and a corresponding plane is correspondingly disposed at a position corresponding to another part such as a fixing element  4123 , a convex-type element  4121 , and the anti-extraction element  50 ), so as to limit mutual rotation between the first tube body  10  and the second tube body  40 . 
         [0027]    In an embodiment, as shown in  FIG. 1  and  FIG. 3 , the pulling rod switch locking structure  74  includes the external thread  741  disposed between the shaft-neck portion  732  and the shaft-tail portion  733  and the threaded hole  42112  that is formed corresponding to an inner thread, disposed at the hole  42111  of the end surface  4211  of the sheath structure  421 , of the external thread  741 . The switch button  731  is extracted and then rotated, to enable the external thread  741  to be engaged with the threaded hole  42112 , so that the compression spring  734  is pushed to a limit to keep the pulling rod switch  73  at the extracted position, and after the switch button  731  is rotated in an opposite direction to enable the external thread  741  to leave the threaded hole  42112 , the pulling rod switch  73  is pulled back to the original position by means of the elastic resilience of the compression spring  734 , so that the spring pin component  60  can reset the insertion pin  613  to enable the first tube body  10  and the second tube body  40  to return to a state of being locked. 
         [0028]    In another embodiment (as shown in  FIG. 6  and  FIG. 7 ), the pulling rod switch locking structure  74 ′ includes a fastening ring block  742  disposed between the switch button  731  and the outer side of the end surface  4211  of the sheath structure  421 . The fastening ring block  742  has an insertion groove  7421 , and the shaft-neck portion  732  is clamped and held in the insertion groove  7421 , so that the pulling rod switch  73  is kept at the extracted position, and after the fastening ring block  742  is removed, the pulling rod switch  73  is pulled back to the original position by means of the elastic resilience of the compression spring  734 . Certainly, to use the fastening ring block  742  at any time, the fastening ring block  742  may be tied on the switch button  731  by using a rope  7422  or chain (not shown). 
         [0029]    Please continue to refer to  FIG. 1  and  FIG. 2 . The neck-portion structure  122  may be the inward turning surface  1222  of the small inner diameter space  1221  whose diameter is less than the diameter of the intra-tube space. That is, the tail-end portion  12  of the first tube body  10  has a sub-step tube  123  having a relatively small diameter. The first pinhole  13  in the foregoing embodiment may be disposed on a tube body of the sub-step tube  123 , and an intra-tube portion of the sub-step tube  123  may also naturally form the neck-portion structure  122 . 
         [0030]    It should be noted that, in the foregoing embodiment, the top rod structure  412  may be directly implemented by using the end surface  411  of the head end  41  of the second tube body  40 , to push a concave area of a can body bottom portion A 5  to form sealing, or, in this embodiment, a hole  4111  is provided on the end surface  411  of the head end  41  of the second tube body  40 , and the top rod structure  412  is disposed inside the second tube body  40  and sequentially includes a convex-type element  4121  having a top rod  41211 , a compression spring  4122 , and a fixing element  4123 . The fixing element  4123  is fixedly screwed on an inner wall of the second tube body  40  by applying a screw  41231  to support the compression spring  4122 , so that the convex-type element  4121  is pushed upward by the compression spring  4122 , the top rod  41211  protrudes from the hole  4111 , and a shortened travel length after the compression spring  4122  is pressed is less than a length by which the top rod  41211  protrudes from the hole  4111 . In other words, when position locking between the first tube body  10  and the second tube body  40  is released, and the sheath structure  421  is held and pushed toward the first tube body  10 , after the top rod  41211  of the convex-type element  4121  pushes the can body bottom portion A 5  of the irritant gas can A, the convex-type element  4121  stops pushing temporarily; instead, the compression spring  4122  absorbs a pushing force from the sheath structure  421 , and when the compression spring  4122  is shortened to a limit, the convex-type element  4121  may be pushed again to enable the end surface  411  of the second tube body  40  and the top rod  41211  to push the can body bottom portion AS of the irritant gas can A, so that the recessed seat  21  presses the press-ring portion A 2  to spray the contents A 3 . That is, the press-ring portion A 2  in front is subject to a pushing force from behind and a blocking limit of the recessed seat  21  in front, and the can body top portion A 4  compresses the compression elastic piece  30  to a limit, so as to spray the contents A 3  from the output tube Al 
         [0031]    In addition, to keep a spray path of the irritant gas can A unobstructed, when a defense spray function is not used, an end plug  22  (the end plug  22  has a water-proof function) inserted in the through hole  211  is further included on a surface, opposite the receiving chamber  111 , of the cap  20 ; however, before the defense spray function is used, the end plug  22  must be removed. 
         [0032]    Please continue to refer to  FIG. 1 ,  FIG. 9 ,  FIG. 10 , and  FIG. 11 . A bolted telescopic rod-type defense spray apparatus  1 ′ in this embodiment includes members such as the first tube body  10 , the head-end portion  11 , the cap  20 , the second tube body  40 , and the sheath structure  421  in the foregoing corresponding embodiment of two sectioned rods, and further includes an umbrella component  80  to form an umbrella-type defense spray apparatus. A rod body that includes the first tube body  10  and the second tube body  40  forms a central rod  801  of the umbrella component  80 .
