Description

Technical Field

[0001] This utility model relates to the field of label box technology, specifically a cash register scale. Background Technology

[0002] In the retail industry, the main body of the cash register scale is a commonly used weighing and checkout device, and its accompanying label holder requires frequent label replacement and maintenance. Currently, the label holder is mostly fixed to the main body of the cash register with bolts, while the cover is connected to the holder via a single-sided pivot, allowing the cover to rotate and open. However, due to the limited rotation angle of the cover, the bolt holes are often obstructed by the cover itself, resulting in a narrow operating space and difficulty in aligning tools perpendicularly with the screw holes. This easily leads to stripped threads or loose screws, resulting in low efficiency when maintaining or replacing label consumables and affecting the continuity of checkout operations. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cash register scale to solve the problems mentioned in the background section.

[0004] Most existing label boxes are fixed to the main body of the cash register with bolts, while the cover is connected to the box body by a single-sided pivot, allowing the cover to rotate around the pivot and open. However, due to the limited rotation angle of the cover, the bolt holes are often blocked by the cover itself, resulting in a narrow operating space and difficulty in aligning tools vertically with the screw holes. This can easily lead to stripped threads or screws falling off, resulting in low efficiency when maintaining or replacing label consumables and affecting the continuity of cash register operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0025] 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.

[0026] Please see Figures 1-9 This utility model provides a technical solution: a cash register scale, including a cash register scale body 1 and a label box body 2. The label box body 2 is detachably connected to the inside of the cash register scale body 1 by bolts. The bolts are located inside the label box body 2. A cover plate 3 is detachably connected to one side of the label box body 2. When the label box body 2 is installed inside the cash register scale body 1, the cover plate 3 is removed from one side of the label box body 2 to prevent the cover plate 3 from obstructing the position of the bolts and affecting the efficiency of disassembly and assembly. The inside of the label box body 2 is symmetrically provided with connecting holes 4. A fixing plate 6 is fixedly connected to the inside of the cover plate 3. A limit plate 5 is fixedly connected to one side of the fixing plate 6. There are two sets of limit plates 5, which are centrally symmetrical and limit the rotation range of the connecting frame 13. A movable plate 8 is symmetrically slidably connected inside the fixing plate 6. Slider blocks are fixedly connected to both sides of the moving plate 8. Slide grooves are symmetrically opened inside the fixed plate 6. The outer side of the slider is slidably connected to the slide groove, and the outer side of the slider fits into the slide groove, ensuring the stability of the moving plate 8 within the fixed plate 6. A connecting post 7 is fixedly connected to one end of the moving plate 8. The moving plate 8 moves along with the connecting post 7. The end of the connecting post 7 away from the moving plate 8 extends to the outside through one side of the cover plate 3. The connecting post 7 is used in conjunction with the connecting hole 4. The connecting post 7 enters the connecting hole 4 and connects the label box body 2 and the cover plate 3 together. A spring 18 is fixedly connected between one end of the moving plate 8 and the fixed plate 6. The moving plate 8 compresses the spring 18. The spring 18 generates elastic force when compressed. When the spring 18 loses its compressive force, the spring 18 returns to its original position along with the moving plate 8 under the action of the elastic force.

[0027] Furthermore, a connecting frame 13 is rotatably connected to one side of the fixed plate 6, and an adjusting rod 17 is rotatably connected to both ends of the connecting frame 13. The connecting frame 13 rotates and moves the adjusting rod 17.

[0028] Furthermore, the end of the adjusting rod 17 away from the connecting frame 13 is rotatably connected to the moving plate 8, and the movement of the adjusting rod 17 moves the moving plate 8.

[0029] Furthermore, a rotating shaft 14 is fixedly connected to the side of the connecting frame 13 away from the fixed plate 6. A ratchet 15 is fixedly connected to the outer side of the rotating shaft 14. The rotation of the rotating shaft 14 causes the ratchet 15 to rotate. A rotating rod 9 is rotatably connected to one side of the fixed plate 6. A pawl 11 is fixedly connected to one end of the rotating rod 9. The rotation of the pawl 11 causes the rotating rod 9 to rotate. The pawl 11 works in conjunction with the ratchet 15. One end of the pawl 11 is located between the two teeth of the ratchet 15 to prevent the ratchet 15 from reversing and causing the connecting post 7 to leave the connecting hole 4.

[0030] Furthermore, one end of the rotating shaft 14 passes through one side of the ratchet 15 and is fixedly connected to a turntable 16. The rotation of the turntable 16 causes the rotating shaft 14 to rotate.

[0031] Furthermore, a torsion spring 10 is fixedly connected between one side of the pawl 11 and the fixed plate 6. When the pawl 11 rotates, it causes one end of the torsion spring 10 to rotate, and the torsion spring 10 deforms. When one end of the torsion spring 10 loses its driving force, the torsion spring 10 and the pawl 11 return to their original position under the action of the elastic force.

[0032] Furthermore, a handle 12 is fixedly connected to one side of the pawl 11, and the movement of the handle 12 causes the pawl 11 to rotate.

[0033] When disassembling the label box body 2, the handle 12 is rotated to turn the pawl 11, causing one end of the pawl 11 to move away from one side of the ratchet 15. The turntable 16 is then rotated, causing the connecting frame 13 to rotate via the shaft 14. This rotation of the connecting frame 13 causes the adjusting rods 17 at both ends to rotate, which in turn moves the moving plate 8 towards the spring 18. As the moving plate 8 moves, it also moves the connecting post 7, gradually disengaging it from the two sets of connecting holes 4 inside the label box body 2. This loosens the connection between the label box body 2 and the cover plate 3, allowing the cover plate 3 to be removed from one side of the label box body 2, directly exposing all the bolt holes inside the label box body 2. This facilitates the disassembly of the bolts connecting the label box body 2 to the cash register body 1, preventing the cover plate 3 from obstructing the bolt holes during disassembly. The tool is difficult to operate vertically, and the bolts are prone to stripping. When it is necessary to reinstall the cover plate 3, simply move the pawl 11 by the handle 12, and then move the cover plate 3 into the label box body 2. During the movement, the connecting posts 7 on both sides of the cover plate 3 are squeezed, which moves the moving plate 8 towards the spring 18. The spring 18 is squeezed and generates elastic force. When the moving plate 8 moves, it moves the two sets of adjusting rods 17. The moving adjusting rods 17 move and rotate the connecting frame 13. The rotation of the connecting frame 13 causes the rotating shaft 14, ratchet 15 and turntable 16 to rotate. When the connecting post 7 moves to one side of the connecting hole 4, the spring 18 loses its pressing force. Under the action of the elastic force, the spring 18 moves the connecting post 7 into the connecting hole 4 through the moving plate 8. Release the handle 12 and let the pawl 11 return to the side of the ratchet 15 to prevent the rotating shaft 14 from reversing, so that the label box body 2 and the cover plate 3 are more firmly connected together.
