[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 7As shown, this utility model provides a cash register that is easy to disassemble, including a base 1, with bolts 2 at each of the four corners of the base 1, a support frame 3 that can be detachably installed inside the base 1, a back plate 4 that is fixedly installed on the top of the support frame 3, and a display panel 5 that is rotatably installed on the front side of the back plate 4.

[0028] The back panel 4 has an internal telescopic groove 6, and the display panel 5 has an internal mounting groove 7. The telescopic groove 6 and the mounting groove 7 are positioned opposite each other. An mounting block 8 is movably installed inside the telescopic groove 6. The top of the mounting block 8 is located inside the mounting groove 7, and the mounting block 8 and the telescopic groove 6 are elastically connected by a first spring 9. The outer wall of the back panel 4 has a vertical groove 10. A control rod 11 is movably installed inside the vertical groove 10. The control rod 11 is fixedly connected to the mounting block 8. Positioning plates 12 are installed on both the left and right sides of the front end of the back panel 4. Fixing holes 13 are opened inside both sets of positioning plates 12. Positioning grooves 14 are opened on both the left and right sides of the rear end of the back panel 4. The positioning plates 12 are located inside the positioning grooves 14.

[0029] By default, the base 1 is mounted on the cashier's countertop by bolts 2. When it is necessary to disassemble the back panel 4 and the display panel 5, the operator pushes the control lever 11 downwards along the vertical groove 10, causing the mounting block 8 to move downwards along the telescopic groove 6. Further, the mounting block 8 disengages from the interior of the mounting groove 7. Then, the operator holds the control lever 11 down and slightly bends the display panel 5 forward. Because the back panel 4 and the display panel 5 are rotatably connected, the display panel 5 rotates forward about its rotation axis. When the display panel 5 is bent, the positioning plate 12 is forced to move away from the positioning groove 14. Since the positioning plate 12 has a fixing hole 13 on its outer wall, the fixing hole 13 presses against the fixing head 16, retracting the fixing head 16 into the interior of the back panel 4. It is worth noting that during the entire disassembly process of the back panel 4 and the display panel 5, pressing the control lever 11 alone will release the fixed relationship between the back panel 4 and the display panel 5. However, the fixing head 16 will abut against the fixing hole 13 through the elastic potential energy of the second spring 15, thereby fixing the positioning plate 12. It is necessary for the staff to turn it to complete the disassembly. This double fixing method prevents the control lever 11 from being accidentally touched. After the disassembly and maintenance are completed, the staff will lift the display panel 5 to reset it. During the reset, the inclined surface of the mounting block 8 will be pressed into the interior of the telescopic groove 6 by the display panel 5. After the display panel 5 is fully reset, the telescopic groove 6 and the mounting groove 7 are aligned with each other, so that the mounting block 8 is reset, and the back panel 4 and the display panel 5 are fixed again.

[0030] By pressing down on the control lever 11, the mounting block 8 is retracted into the telescopic groove 6. Furthermore, by gently moving the display panel 5, the positioning plate 12 is disengaged from the positioning groove 14, completing the disassembly of the back plate 4 and the display panel 5. Compared with traditional devices, the back plate 4 of this device is quick to install and remove, facilitating the maintenance of the components inside the display panel 5. Moreover, the design of the fixing head 16 achieves double fixation, preventing accidental activation of the control lever 11, ensuring installation stability, improving work efficiency, and reducing workload.

[0031] Among them, mounting columns 17 are fixedly installed on the left and right sides of the bottom of the support frame 3, and the mounting columns 17 penetrate into the interior of the base 1.

[0032] The base 1 has a fixing groove 18 inside, and two sets of fixing rods 19 are movably installed inside the fixing groove 18. One end of the two sets of fixing rods 19 passes through the inside of the mounting column 17 to fix the mounting column 17. The other end of the two sets of fixing rods 19 is fixedly installed with racks 20. The two sets of racks 20 are located at the upper and lower ends inside the fixing groove 18. A gear 21 is rotatably installed inside the fixing groove 18. The gear 21 is located between the two sets of racks 20 and meshes with the racks 20.

[0033] When it is necessary to disassemble the display panel 5 as a whole, the operator turns the knob 25 to rotate the worm gear 24. The rotation of the worm gear 24 drives the worm wheel 23 connected to it to rotate. The worm wheel 23 is fixedly connected to the gear 21, so that the gear 21 starts to rotate synchronously. Both the upper and lower ends of the gear 21 mesh with the rack 20, so that the rotation of the gear 21 drives the two sets of fixing rods 19 to move inward synchronously through the rack 20. At this time, the fixing rods 19 leave the interior of the mounting column 17, and the operator can remove the support frame 3 as a whole to complete the disassembly.

[0034] Rotating the knob 25 causes the worm gear 24 to rotate, and through the transmission of the worm wheel 23, the gear 21 drives the two sets of racks 20 to move, pulling the two sets of fixed rods 19 inward, further enabling the support frame 3 to be disassembled. Compared with traditional devices, this device can not only disassemble the back plate 4 separately, but also disassemble the back plate 4 and the display panel 5 as a whole through the support frame 3, making it convenient to remove for maintenance, reducing the disassembly and assembly burden of the staff, and improving user satisfaction.

[0035] The mounting block 8 is a right trapezoid with its inclined surface facing forward. The top of the mounting block 8 abuts against the inner wall of the mounting groove 7 through the elastic potential energy of the first spring 9.

[0036] When the display panel 5 is reset, the inclined surface of the mounting block 8 is pressed into the interior of the telescopic groove 6 by the display panel 5. After the display panel 5 is fully reset, the telescopic groove 6 and the mounting groove 7 align with each other, causing the mounting block 8 to reset and fixing the back plate 4 and the display panel 5 again.

[0037] The positioning groove 14 has a fixed head 16 movably installed inside it, and one end of the fixed head 16 is elastically connected to the inner wall of the positioning groove 14 by a second spring 15.

[0038] The fixing head 16 will abut against the fixing hole 13 through the elastic potential energy of the second spring 15, thereby fixing the positioning plate 12.

[0039] One end of the fixing head 16 abuts against the fixing hole 13, and the end of the fixing head 16 that abuts against the fixing hole 13 is dome-shaped.

[0040] The dome-shaped design of the fixing head 16 makes it necessary for staff to pry open the back panel 4 and the display panel 5 to complete the disassembly.

[0041] The base 1 has a fixed shell 22 fixedly installed on its rear side wall. A worm gear 23 is rotatably installed inside the fixed shell 22. One end of the worm gear 23 is fixedly connected to the gear 21.

[0042] The worm gear 23 and worm 24 are connected by a transmission, and the worm gear 23 and gear 21 are fixedly connected to achieve transmission operation.

[0043] The fixed shell 22 has a worm gear 24 rotatably mounted inside, and the worm gear 24 is connected to the worm wheel 23. The fixed shell 22 has a knob 25 rotatably mounted on its outer wall, and the knob 25 is fixedly connected to the worm gear 24.

[0044] Working principle and usage process of this utility model:

[0045] By default, the base 1 is mounted on the cashier's countertop by bolts 2. When it is necessary to disassemble the back panel 4 and the display panel 5, the operator pushes the control lever 11 downwards along the vertical groove 10, causing the mounting block 8 to move downwards along the telescopic groove 6. Further, the mounting block 8 disengages from the interior of the mounting groove 7. Then, the operator holds the control lever 11 down and slightly bends the display panel 5 forward. Because the back panel 4 and the display panel 5 are rotatably connected, the display panel 5 rotates forward about its rotation axis. When the display panel 5 is bent, the positioning plate 12 is forced to move away from the positioning groove 14. Since the positioning plate 12 has a fixing hole 13 on its outer wall, the fixing hole 13 presses against the fixing head 16, retracting the fixing head 16 into the interior of the back panel 4. It is worth noting that during the entire disassembly process of the back panel 4 and the display panel 5, pressing the control lever 11 alone will release the fixed relationship between the back panel 4 and the display panel 5. However, the fixing head 16 will abut against the fixing hole 13 through the elastic potential energy of the second spring 15, thereby fixing the positioning plate 12. It is necessary for the staff to turn it to complete the disassembly. This double fixing method prevents the control lever 11 from being accidentally touched. After the disassembly and maintenance are completed, the staff will lift the display panel 5 to reset it. During the reset, the inclined surface of the mounting block 8 will be pressed into the interior of the telescopic groove 6 by the display panel 5. After the display panel 5 is fully reset, the telescopic groove 6 and the mounting groove 7 are aligned with each other, so that the mounting block 8 is reset, and the back panel 4 and the display panel 5 are fixed again.

[0046] When it is necessary to disassemble the display panel 5 as a whole, the operator turns the knob 25 to rotate the worm gear 24. The rotation of the worm gear 24 drives the worm wheel 23 connected to it to rotate. The worm wheel 23 is fixedly connected to the gear 21, so that the gear 21 starts to rotate synchronously. Both the upper and lower ends of the gear 21 mesh with the rack 20, so that the rotation of the gear 21 drives the two sets of fixing rods 19 to move inward synchronously through the rack 20. At this time, the fixing rods 19 leave the interior of the mounting column 17, and the operator can remove the support frame 3 as a whole to complete the disassembly.
