Technical Field
[0001] This utility model relates to the technical field of keyboard disassembly and assembly structure, specifically a keyboard disassembly and assembly structure for a cash register scale. Background Technology
[0002] A cash register scale is a pricing scale with individual item management functions, mainly used for checkout. A dual-screen cash register scale is a type of cash register scale with two large screens. The main screen is for cashier operation, while the secondary screen faces the customer, displaying product information, prices, and total prices. It is widely used in large shopping malls, chain stores, and farmers' markets.
[0003] In existing technologies, the keypad of a cash register scale is usually fixedly mounted on the scale body. Over time, dirt and grime easily accumulate on the exterior of the scale body, making it inconvenient to disassemble and clean separately. The disassembly and assembly process is cumbersome and inconvenient to use. Therefore, we propose a keypad disassembly and assembly structure for cash registers. Utility Model Content

As the usage time increases, some stains easily adhere to the outside of the scale body, making it inconvenient to disassemble and clean it separately, and the disassembly and assembly steps are relatively cumbersome.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A POS scale keyboard assembly / disassembly structure includes a scale body, a keyboard on one side of the scale body, and connecting seats fixedly connected at equal intervals to the bottom of the keyboard. A sliding groove is formed inside the connecting seat, and a slider is slidably connected inside the sliding groove. A locking block is fixedly connected to one side of the slider, and the locking block is slidably connected to the connecting seat. A push rod is slidably connected between two connecting seats, and a connecting rod is fixedly connected at equal intervals to the outer side of the push rod. The slider is fixedly connected to the connecting rod. A fixing base is fixedly connected to the bottom of the scale body, and the fixing base has slots at equal intervals inside that cooperate with the locking block. By moving the locking block into the slot, the position of the connecting seat can be locked, facilitating the installation of the keyboard.
[0007] Preferably, the inner wall of the slide is fixedly connected with limit rods at equal intervals, the connecting rod is slidably connected to the limit rods, and the connecting rods are provided with limit grooves at equal intervals inside to cooperate with the limit rods.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 8 This utility model provides a technical solution:
[0024] A keypad assembly / disassembly structure for a cash register scale includes a scale body 1. A keypad 3 is located on one side of the scale body 1. Connecting seats 4 are fixedly connected to the bottom of the keypad 3 at equal intervals. A sliding groove 9 is provided inside the connecting seat 4. A slider 10 is slidably connected inside the sliding groove 9. A locking block 8 is fixedly connected to one side of the slider 10. The locking block 8 is slidably connected to the connecting seat 4. A push rod 6 is slidably connected between the two connecting seats 4. A connecting rod 13 is fixedly connected to the outside of the push rod 6 at equal intervals. The slider 10 is fixedly connected to the connecting rod 13. A fixing seat 2 is fixedly connected to the bottom of the scale body 1. The fixing seat 2 has slots 16 at equal intervals inside, which cooperate with the locking block 8. By moving the locking block 8 into the slot 16, the position of the connecting seat 4 can be locked, facilitating the installation and fixing of the keypad 3. By pushing the push rod 6 to drive the connecting rod 13 to slide, the connecting rod 13 drives the locking block 8 to move through the slider 10, causing the locking block 8 to move out of the slot 16, allowing for quick assembly / disassembly of the keypad 3. The operation is convenient.
[0025] Furthermore, the inner wall of the slide 9 is fixedly connected with limit rods 12 at equal intervals, and the connecting rod 13 is slidably connected with the limit rods 12. The connecting rod 13 is provided with limit grooves 14 at equal intervals inside to cooperate with the limit rods 12. The movement of the connecting rod 13 can be limited by the setting of the limit rods 12 and the limit grooves 14 to prevent the connecting rod 13 from deviating when moving.
[0026] Furthermore, a reset spring 11 is provided between the slider 10 and the connecting seat 4. One end of the reset spring 11 is fixedly connected to the slider 10, and the other end of the reset spring 11 is fixedly connected to the inner wall of the connecting seat 4. The reset spring 11 can drive the slider 10 to move and reset, and the slider 10 drives the locking block 8 to move.
[0027] Furthermore, a push block 5 is fixedly connected to one end of the push rod 6, and the push rod 6 is moved by the push block 5.
[0028] Furthermore, anti-slip protrusions 7 are fixedly connected at equal intervals on one side of the push block 5. The anti-slip protrusions 7 can increase the friction force and facilitate pushing the push block 5.
[0029] Furthermore, the fixed base 2 has slots 15 that are equidistantly provided inside for use with the connecting base 4. The slots 15 can be used with the connecting base 4 to assist in the quick assembly and disassembly of the keyboard 3.
[0030] Working principle:
[0031] When installing the keyboard 3, first connect the keyboard 3's wiring to the scale body 1. Then, push the connector 4 into the slot 15. During the pushing process, because one side of the locking block 8 is inclined, the locking block 8 will slide due to the pressure of the fixing seat 2. The locking block 8 drives the slider 10 to slide along the inner wall of the slide groove 9, and the return spring 11 is compressed. When one end of the connector 4 is fully inserted into the slot 15, the return spring 11 will move the slider 10 to reset due to its elasticity. The slider 10 then moves the locking block 8 into the slot. The keyboard 3 is installed by locking the connector 4 inside the slot 16. When the keyboard 3 needs to be disassembled for cleaning, push the push block 5. The anti-slip protrusions 7 increase the friction, making it easier to push the push block 5. The push block 5 drives the push rod 6 to move. The push rod 6 drives the connecting rod 13 to slide along the limit rod 12. The connecting rod 13 drives the locking block 8 to move through the slider 10, so that the locking block 8 moves out of the slot 16, and the keyboard 3 can be removed for cleaning. The operation is convenient and easy to use.
