Title: Moving and locating device of padding plate

Description:
BACKGROUND OF INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a moving and locating device of padding plate, and more particularly to an innovative one which could change its moving or locating state very conveniently by adjusting the snapping relationship between movable poker block of the disk and locating hole of the padding plate. 
     2. Description of the Prior Art 
     In response to the operating requirements at different angles, the padding plate is used for alignment and measurement purposes. Hence, a padding plate structure with rotating angle has been developed. Referring to  FIGS. 1 ,  2 , it mainly comprises an upper pad  10  and a lower pad  11 ; a through-hole  12  is placed centrally onto the lower pad  11 , and a rivet  13  is punched to bind the upper pad  10  and lower pad  11 ; in practice, the lower pad  11  is used as a rotary basement, and upper pad  10  rotates randomly by circling around the rivet  13  to realize multi-angle operation of the padding plate. 
     However, the following shortcomings are observed during rotation control of the padding plate: 
     1. Poorer rotation efficiency: as the rivet is mated with the lower pad, the lower pad may be driven to displace the basement when the upper pad is rotated by the operator in the job processing. In such case, the operator must firstly press down the lower pad, and then rotate the upper pad smoothly, making this operation inconvenient. 
     2. Possible damage of rivet structure: as the rivet is directly fixed onto the upper pad, the rivet structure may be damaged, or disengaged from the padding structure due to long-lasting reverse friction of lower pad or misoperation of the operator. 
     3. Inability of changing the operating status: the operator cannot, where necessary, adjust the padding plate into rotary or fixed state. 
     SUMMARY OF THE INVENTION 
     In view of the existing shortcomings of the padding plate&#39;s rotating structure, the inventor intends to make an improvement by placing a disk into the lower padding plate, where there is a movable poker block. When the upper padding plate is mated with the lower padding plate, the snapping relation between the poker block and bottom locating hole of the upper padding plate could be controlled by adjusting the position of the poker block, such that the upper padding plate can be placed in a rotary or fixed state, where necessary. Another objective of the present invention is to rotate the upper padding plate quickly, flexibly and conveniently by sleeving the disk only with a slot as the disk is not coupled with the upper padding plate. This could eliminate the possible displacement of lower padding plate or damage of rotary mechanism during rotation of the padding plate.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The structural composition and technical efficacies of the present invention are described below with reference to the preferred embodiments: 
     Referring to FIG.  3 —an exploded view of the disk, wherein several footsteps  22  are protruded laterally from the disk body  21 , while a notched groove  23  is placed internally from outer edge of the disk body  21 ; a wide/narrow section  27 ,  28  is formed laterally on the notched groove  23 , whilst a track  24  is arranged at both sides of the notched groove  23 , and front/rear recessed holes  25 ,  26  preset correspondingly on two tracks  24 ; a poker block  30  is built-into the notched groove  23 ; at both sides of the poker block  30 , a groove  32  aligned to the track  24  of notched groove  23  is placed internally, and a bulge  33  is placed correspondingly in the groove  32 ; a wide/narrow section  34 ,  35  is also arranged laterally on the poker block  30 , and two poker holes  31  are set on the poker block  30 , enabling the operator to shift the poker block  30 . 
     Referring to  FIG. 4-1  and  4 - 2 , the poker block  30  can flexibly move within the notched groove  23  of the disk body  21 , and the bulge  33  of the groove  32  is locked securely into the front/rear recessed hole  25 ,  26  of the track  24 , then the narrow section  28  of the notched groove  23  could limit the wide section  34  of the poker block  30  against the protrusion of poker block  30 . 
     Referring also to  FIGS. 5 ,  6  and  7 , it mainly comprises an upper padding plate  40 , a lower padding plate  50  and a disk  20 ; the upper padding plate  40  is composed of an upper top plate  41  and an upper base plate  42 ; of which, a slot  412  is preset at the bottom of the upper top plate  41 , and a locating hole  411  is protruded laterally from the slot  412 ; the upper base plate  42  is provided with the slot  422  and locating hole  421  correspondingly to the upper top plate  41 ; the lower padding plate  50  is composed of a lower top plate  51 , a lower plywood  52  and a lower base plate  53 ; of which, the lower top plate  51  and lower plywood  52  are provided with a slot  512 ,  522 , at one side of which a locating hole  511 ,  521  is arranged; several foot holes  523  corresponding to the footstep  22  of disk  20  are arranged at one side of the slot  522  of the lower plywood  52 ; moreover, the disk  20  is arranged onto the lower base plate  53 , and the lower plywood  52  and lower top plate  51  are overlapped on the lower base plate  53  in sequence, so that the disk  20  can be fixed within the lower padding plate  50 ; when the upper padding plate  40  is covered on the lower padding plate  50 , the disk  20  is mated with the slot  422  of the upper base plate  42 . 
     Referring also to  FIGS. 8 and 9 , when the poker block  30  is recessed into the disk body  21 , the poker block  30  is combined with the disk body  21  in a round shape, without any snapping relation with the locating hole  421  of the upper base plate  42 . So, the upper padding plate  40  may rotate quickly around the disk  20  in a controlled way; furthermore, referring to  FIGS. 10 and 11 , when the poker block  30  is extended into the disk body  21  and engaged with the locating hole  511 ,  521  of the lower top plate  51  and lower plywood  52 , the poker block  30  is snapped with the locating hole  421  of the upper base plate  42 , so that the upper padding plate  40  is limited in a fixed state; apart from the bonding of the upper padding plate  40  and lower padding plate  50 , the upper padding plate  40  could be used independently from the lower padding plate  50 . 
     Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
