Description

Technical Field

[0001] The present invention relates to the technical field of cash boxes, and in particular to a mechanical touch cash box. Background Art

[0002] Cash boxes are used for cashiers in places such as shopping malls and supermarkets. During use, the cash box needs to be opened and closed at any time. Most of the current cash boxes on the market are controlled by electric drive to open and close. The structure is as follows: A drawer is slidably arranged in the box body. A key lock is arranged between the drawer and the box body. An electromagnet and a compression spring are arranged in the box body. An iron block is arranged on the rear wall of the drawer. During use, for the convenience of cashiers, the staff uses a key to open the key lock, and then realizes the opening and closing of the cash box by the attraction and separation between the electromagnet and the iron block in the cash box. When the drawer is pushed into the box body, the electromagnet is energized to generate magnetic force. The drawer drives the iron block to approach the electromagnet after overcoming the elastic force of the compression spring until the iron block is attracted to the electromagnet, and the drawer is locked in the box body, and the cash box is closed. When the electromagnet is powered off, there is no magnetic force between the electromagnet and the iron block, and the drawer moves out of the box body under the action of the elastic force of the compression spring, and the cash box is opened. This kind of cash box with an electric drive structure not only has a high cost, but also needs to be in the powered-on state to operate normally. If a power failure occurs, a key is needed to lock the drawer in the box body, which is very inconvenient. Summary of the Invention

In order to improve the stability of the transmission plate 33, the transmission plate 33 needs to be abutted against the Z-shaped connecting frame 31 between the left boss 313 and the right boss 314. Due to the characteristics of the riveting structure of the third rivet 6, the third rivet 6 will extend downward out of the transmission plate 33, so an avoidance hole 316 that does not interfere with the front-back and left-right movement of the third rivet 6 needs to be arranged on the Z-shaped connecting frame 31. The shape of the avoidance hole 316 can be selected as various shapes such as square, circular, polygonal, etc. The avoidance hole 316 in this embodiment is square. A limiting plate 34 capable of being clamped into the rabbet 321 is rotatably arranged on the Z-shaped connecting frame 31 behind the transmission plate 33, and the limiting plate 34 is rotatably arranged on the right boss 314.A limiting post 317 capable of limiting the limiting plate 34 is provided on the right convex platform 314. The limiting post 317 prevents the limiting plate 34 from rotating excessively and getting stuck. A first hook 331 higher than the limiting post 317 is provided at the rear end of the transmission plate 33. A second hook 328 at the same height as the first hook 331 is provided at the front right side of the moving lock plate 32. A right tension spring 7 is connected between the first hook 331 and the second hook 328. A third hook 341 is provided in the middle of the limiting plate 34. A fourth hook 329 at the same height as the third hook 341 is provided at the rear left side of the moving lock plate 32. A left tension spring 8 is connected between the third hook 341 and the fourth hook 329. The compression spring 312 extends forward out of the Z-shaped connecting frame 31 and the moving lock plate 32. The position of the moving lock plate 32 is lower than the position of the connecting block 21. In this way, when the lock rod shaft 22 extends out of the lower half of the connecting block 21 and cooperates with the mechanical lock 3, the connecting block 21 will not interfere with the mechanical lock 3.,

[0019] The working principle is as follows: When the cash box needs to be closed, the drawer 2 is pushed into the box body 1. After the drawer 2 overcomes the elastic force of the compression spring 312, it drives the lock rod shaft 22 to move into the sliding groove 315 and the guide groove 322 and push the transmission plate 33 backward. Due to the guiding action of the first conical groove and the second conical groove, the lock rod shaft 22 can quickly and accurately enter the sliding groove 315 and the guide groove 322. After the transmission plate 33 receives the pushing force of the lock rod shaft 22, it moves backward against the pulling force of the right tension spring 7 and pushes the limiting plate 34 backward through the first hook 331. After the limiting plate 34 receives the pushing force of the transmission plate 33, it rotates backward and leaves the stop 321 on the moving lock plate 32. The drawer 2 is released, and the moving lock plate 32 moves to the right along the waist-shaped groove 325 and the first waist-shaped hole 326 under the pulling force of the left tension spring 8. The hook groove 323 on the moving lock plate 32 is blocked in front of the lock rod shaft 22. At this time, the moving lock plate 32 drives the transmission plate 33 to move to the right together. The transmission plate 33 is no longer in contact with the lock rod shaft 22. The transmission plate 33 returns forward under the action of the right tension spring 7. The transmission plate 33 no longer pushes the limiting plate 34. The limiting plate 34 abuts against the rear side wall of the moving lock plate 32 under the pulling force of the left tension spring 8. The drawer 2 is locked in the box body 1, and the cash box is closed;

[0020] When it is necessary to open the cash box, gently push the drawer 2. The drawer 2 drives the lock rod shaft 22 to move backward along the chute 315. During the backward movement of the lock rod shaft 22, it acts on the guiding inclined wall 324 to exert a leftward thrust on the moving lock plate 32. Under the action of the thrust, the moving lock plate 32 moves leftward along the waist-shaped groove 325 and the first waist-shaped hole 326. At this time, the transmission plate 33 moves leftward together under the action of the moving lock plate 32. However, after the transmission plate 33 is blocked by the lock rod shaft 22, it will rotate counterclockwise around the third rivet 6. After the transmission plate 33 rotates, it will no longer contact the limiting plate 34. When the moving lock plate 32 moves leftward, it pulls the limiting plate 34 to rotate forward through the left tension spring 8. When the moving lock plate 32 moves leftward in place, the limiting plate 34 snaps forward into the stop 321 of the moving lock plate 32 to fix the moving lock plate 32. At this time, the hook groove 323 no longer blocks in front of the lock rod shaft 22. Release the drawer 2, and the drawer 2 moves out of the box body 1 under the elastic force of the compression spring 312, and the cash box is opened. At this time, the lock rod shaft 22 also comes out of the chute 315 and the guide groove 322. The transmission plate 33 is no longer blocked by the lock rod shaft 22, and the transmission plate 33 rotates clockwise around the third rivet 6 to reset under the action of the right tension spring 7.
