FIELD OF THE INVENTION  
       [0001]     The present invention relates to locks, and particularly to a press-buckled lock, wherein a press buckle is installed. By pressing the buckle, the door can be locked rapidly. When the inner handle is rotated, the press buckle is separated rapidly to unlock. Other than making the operation easy, the installation of the press buckle at the inner handle of a lock will reduce the manufacturing cost and cause the operation to be easy. Thereby the cost is reduced.  
       BACKGROUND OF THE INVENTION  
       [0002]     In the current used lock, the door handle is combined with the lock. The function of the handle is to reduce a lock tongue of the lock seat inwards so as to separate from the lock tongue seat to achieve the object of unlocking. An outer side of the door lock has a lock hole for receiving a key to rotate therein so as to achieve the object of locking and unlocking. In such a structure, the locking of the door is controlled by rotating the switch at the inner side of a door. It is not a convenient way. The process in manufacturing and installation is completed and the cost is high. It is not an ideal way.  
       SUMMARY OF THE INVENTION  
       [0003]     Accordingly, the primary object of the present invention is to provide a press-buckled lock, wherein a press buckle is used so that the operation of locking and unlocking can be performed rapidly.  
         [0004]     To achieve object, the prior art rotation switch is changed as a press buckle. By pressing the buckle, the door can be locked rapidly. When the inner handle is rotated, the press buckle is separated rapidly to unlock. Other than making the operation easy, the installation of the press buckle at the inner handle of a lock will reduce the manufacturing cost and cause the operation to be easy. Thereby the cost is reduced.

       [0013]     In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.  
         [0014]     With reference to  FIGS. 1, 2 , and  4 , the perspective view, exploded view and cross sectional view of the present invention is illustrated. The present invention includes the following elements.  
         [0015]     An inner sleeve  21  is a hollow body. A washer  20  encloses a middle section of the inner sleeve  21 .  
         [0016]     A press buckle  22  has an extension portion  2201  at a front end thereof. The extension portion  2201  inserts into a rear end of a round sleeve  28 . Another end of the round sleeve  28  has an opening. A spring  29  is installed in the opening. A front end of the round cover  29 . A bottom cover  30  is embedded into the opening of the round sleeve  28 . Then the round sleeve  28  is placed into a rear side of the inner sleeve  21 . The press buckle  22  has a head portion  2202  at a rear end thereof. A spring  26  is installed to the head portion  2202  of the press buckle  22 . A periphery of the spring  26  is enclosed by an actuating sleeve  27 .  
         [0017]     An inner handle  25  has a head portion  2501 . The press buckle  22  with the inner sleeve  21  are received within the inner handle  25 . The head portion  2202  of the press buckle  22  is inserted into a round hole  2502  at one end of the inner handle  25  so as to protrude out of the inner handle  25 . Part of th actuating sleeve  27  is inserted into the head portion  2501  of the inner handle  25  and other part thereof is exposed out of the head portion  2502  of the inner handle  25 . The inner sleeve  21  is received within the inner handle  25  so as to be combined thereto. An upper end of the inner handle  25  is pressed so that a buckle tip  2503  at the inner side of the inner handle  25  (in the drawing, the outer side of the buckled tip  2503  is pressed inwards so that the interior of the inner handle  25  is formed with the buckled tip  2503 ) is buckled into a recess  2102  at an upper side of the inner sleeve  21  so as to prevent the inner handle  25  to move out.  
         [0018]     An inner panel  19  has a central hole. The inner sleeve  21  passes through the inner panel  19  so that the inner panel  19 , inner sleeve  21  and the inner handle  25  are assembled as an integral body. Then a confining sheet  18 , a second resilient spring  17 , and an inner spring seat  16  sequentially pass through the inner panel  19 . An elastic opening ring  15  is embedded into an annular trench  2102  at a front end of the inner sleeve  21  as a confinement.  
         [0019]     An outer sleeve  3  is included, see  FIG. 3-1 . An inner wall of the outer sleeve  3  has two projections  302 . One end of the outer sleeve  3  has four connecting sheets  303 .  
         [0020]     A lock core  2  is combined within the outer sleeve  3 . The lock core  2  has a projection  201 . A front end of the lock core  2  has a guide structure  202 .  
         [0021]     An outer handle  1  has a head portion  101 . An inner side of the outer handle  1  has a buckled tip  103  (in the drawing, the outer side of the buckled tip  103  is pressed inwards so that the interior of the outer handle  1  is formed with the buckled tip  103 ) The outer sleeve  3  and the lock core  2  are placed in the head portion  101  of the outer handle  1 . The projection  201  of the lock core  2  is buckled into a long hole  102  at the head portion  101  of the outer handle  1 . The buckled tip  103  is buckled in a recess  301  on an outer periphery of the outer sleeve  3  so as to prevent the outer handle  1  to protrude out. The guide structure  202  has a plurality of protrusions. A plurality of guiding recess is formed between two protrusions. A top of each protrusion is formed with a tip teeth. The outer sleeve  3  passes through the outer panel  9  and a front section of the outer sleeve  3  protrudes out thereof.  
         [0022]     A buckling rod  8  has front section  802  and a rear section  801  which are as an H shape. A positioning sheet  7  is positioned in a middle section of the two sections  801 ,  802 . The rear section  801  is engaged with a positioning seat  6 . Two sides of the positioning seat  6  have respective ears  601  which are inserted into the lateral recesses  501  at two sides of a positioning unit  5 . Each ear  601  has a penetrating hole  602  corresponding to a penetrating hole  502  in a corresponding recess  501  of the positioning unit  5  for receiving a pin  401  so as to fix the positioning seat  6  to the positioning unit  5 . Thus, the front section  801  of the buckling rod  8  is confined in the positioning unit  5 . Thereby the buckling rod  8 , positioning sheet  7 , positioning seat  6  and positioning unit  5  are formed as an integral body. A front section of the positioning unit  5  has a guide out unit  503  which is formed by a plurality of blocks. A plurality of guide trenches are formed between the blocks. One side of each block (see  FIG. 3-3 ) is an inclined surface so that the block is formed as a tip teeth. A lateral side of the positioning unit  5  has a through hole  504  at a lateral side thereof for receiving a positioning spring  4 .  
         [0023]     With reference to  FIG. 3-3 , it is illustrated that the buckling rod  8 , positioning sheet  7 , positioning seat  6 , and positioning unit  5  are inserted into the outer sleeve  3 . The positioning spring  4  are buckled to the two projections  302  at the inner wall of the outer sleeve  3 . See  FIG. 4 , the four connecting sheets  303  at one end of the outer sleeve  3  are inserted into the lock core  2  so as to confine the buckling rod  8 , positioning sheet  7 , positioning seat  6 , and positioning unit  5  not to fall out. A outer tube  23  is installed between the outer panel  9  and the inner panel  19 . The buckling rod  8  inserts through a first rectangular iron tube  13  and a second rectangular iron tube  14 . The outer tube  23 , first rectangular iron tube  13  and second rectangular iron tube  14  are inserted into a switch hole  2401  of a lock seat  24 . Thereby by driving the two handle, the lock seat  24  is driven to insert a rear section of the buckling rod  8  into the inner sleeve  21  so as to be further inserted into an interior of the press buckle  22  in the inner handle  25  and confine above mentioned elements.  
         [0024]     Referring to  FIG. 4 , a schematic cross view is illustrated, where the present invention is realized to a lock at an outer side of a door. The press buckle  22  of the inner handle  25  can be pressed from the inner side of a door. The guide unit  503  at a front end of the positioning unit  5  pivotally connecting to the buckling rod  8  is driven by the press bar  22  so as to be engaged to the guiding structure  202  of the lock core  2  at the interior of the outer handle  1 . The positioning spring  4  in the positioning unit  5  will buckle the two projections  302  of the outer sleeve  3  so that if it is desired to rotate the outer handle  1  to drive the outer sleeve  3 , the guide out structure  503  at a front end of the positioning unit  5  will be engaged to the guide structure  202  of the lock core  2  so that the outer handle  1  can not be rotated. Thus it can not be opened from outer side.  
         [0025]     With reference to  FIG. 5 , the schematic cross view about the operation of the present invention is illustrated. When a key is inserted into the lock core  2  from the outer handle  1  at the outer side of the door, the rotate of the key will cause the guide structure  202  at the front end of the lock core  2  to rotate. Thus, the guide out structure  503  at the front end of the positioning unit  5  driving by the buckling rod  8  will rotate in the outer sleeve  3  so as to drive the buckling rod  8  to rotate through an angle until the positioning spring  4  in the positioning unit  5  can not be buckled to the two projections  302  at the inner walls of the outer sleeve  3  so as to separate therefrom. As a result, the positioning seat  6 , positioning sheet  7  and the buckling rod  8  driven with the positioning unit  5  are pushed out. The press buckle  22  firmly secured at the distal end of the buckling rod  8  retracts out from the inner sleeve  21  so that the head portion  2202  of the press buckle  22  protrudes out so as to achieve the object of unlocking. The user out of the door may rotate the outer handle  1  to open the door. Furthermore, the hand inside the door will press the press buckle  22  on the inner handle  25  so as to lock the door. Furthermore, the inner handle  25  is rotated to achieve the object of unlocking. at the time of rotating the inner handle  25 , the buckling rod  8  rotates by the driving of the press buckle  22 . As a result, the guiding out structure  503  at the front end of the positioning unit  5  driving by the buckling rod  8  will rotate at the outer side of the outer sleeve  3  so that the positioning seat  6 , positioning sheet  7 , and buckling rod  8  driven by the positioning unit  5  will push out. The positioning spring  4  in the positioning unit  5  will separate from the two projections  302  at the inner wall of the outer sleeve. Similarly, the press bar  22  firmly secured to the distal end of the buckling rod  8  will retract out from the inner sleeve  3  so that the head portion  2202  of the press buckle  22  protrudes out. Thereby the object of unlocking is achieved.  
         [0026]     Advantages of the present invention will be described herein. The present invention has a simple structure so that the manufacturing process is simplified and the cost is reduced. Furthermore, the installation of the press bar causes that the operations of the locking and unlocking are convenient.  
         [0027]     The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
