Detailed Embodiments

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Embodiment 1

[0037] Please refer to Figures 2 to 8 , which is a quick disassembly and assembly structure for the secondary screen of a desktop POS device as Embodiment 1 of the present utility model, used to connect the secondary screen 002 to the vertical rod main body 001. The disassembly and assembly structure includes a first base 10, a locking base 20, and a first locking member 30. The first base 10 is arranged against the vertical rod main body 001; the locking base 20 is arranged on the first base 10 and is embedded in the vertical rod main body 001; the first locking member 30 is locked on the locking base 20 so that the first base 10 abuts against the vertical rod main body 001, that is, after the first locking member 30 is locked on the locking base 20, the first base 10 tightly abuts against the vertical rod main body 001; in this embodiment, the secondary screen 002 is directly arranged on the first base 10 or is rotatably connected to the first base 10 through a second base 40 to realize the rotational adjustment of the secondary screen 002 to adapt to the use of people with different heights. The second base 40 is used to install the secondary screen 002 and is rotatably connected to the first base 10, that is, the second base 40 can be directly arranged on the secondary screen 002. The quick disassembly and assembly structure of the present utility model can realize the quick installation or disassembly of the secondary screen 002 by arranging the locking base 20 on the first base 10 and then using the first locking member 30, that is, by arranging the locking base 20 for embedding the vertical rod main body 001 on the first base 10 and locking the first locking member 30 on the locking base 20.

[0038] Specifically, please refer to Figure 2 , the first base 10 includes a backrest portion 11 that can abut against the vertical rod main body 001 and an extension portion 12 arranged on the backrest portion 11 and forming a certain angle with it. By arranging the extension portion 12, the secondary screen 002 has a certain rotational angle. The angle formed between the extension portion 12 and the backrest portion 11 can be greater than or equal to 90°; the backrest portion 11 and the extension portion 12 are of an integral structure and are formed by stamping a sheet metal part.

[0039] Two locking bases 20 are arranged and are arranged side by side on the first base 10. Correspondingly, two first locking members 30 are arranged. The first base 10 can be directly hung on the vertical rod main body 001 through the two side-by-side arranged locking bases 20, and then locked by the two first locking members 30 to realize quick installation. When disassembly is required, just open the first locking member 30. The whole process is simple and fast to operate.

[0040] A through hole 011 for locking the embedding of the base 20 is provided on the vertical rod main body 001. After the two locking bases 20 are embedded in the through hole 011, the first locking member 30 is screwed to the locking base 20. Therefore, only by presetting the through hole 011 for locking the embedding of the base 20 on the vertical rod main body 001 and matching the locking base 20 with the first locking member 30 can the quick installation and disassembly of the first base 10 be realized.

[0041] For details, please refer to Figure 2 , the first locking member 30 includes a locking portion 31 that cooperates with the locking base 20 and a limiting portion 32 for limiting; an external thread is provided on the outer side wall of the locking portion 31, and an internal thread hole that cooperates with the locking portion 31 is provided on the locking base 20. The limiting portion 32 can not only achieve the limiting function, but also anti-slip lines are provided on the outer side wall of the limiting portion 32, which can realize manual installation and disassembly. Therefore, the utility model adopts a modular design, has the characteristics of simple structure, no need to rely on any tools, and can be quickly disassembled and assembled, solves the pain point of difficult customer upgrade, solves the problem of difficult maintenance of the desktop POS machine, and greatly reduces the customer's use cost and the manufacturer's maintenance cost.

[0042] For details, please refer to Figures 3 to 4 , the quick disassembly and assembly structure of this embodiment also realizes the quick disassembly and installation of the secondary screen 002 and the second base 40. A clamping portion 41 is provided at the upper end of the second base 40, and a card slot 021 for the clamping portion 41 to be embedded is provided on the back surface of the secondary screen 002. The second base 40 is locked to the back surface of the secondary screen 002 through the second locking member 50. Specifically, two clamping portions 41 and two card slots 021 are provided. After the clamping portion 41 is embedded in the card slot 021, the second base 40 is fixed to the back surface of the complex plane through the second locking member 50, and the structure of the second locking member 50 is the same as that of the first locking member 30, or a screw can be directly used.

[0043] For details, please refer to Figures 5 to 8 , the first base 10 and the second base 40 are rotationally connected through a damping assembly 60 to facilitate the adjustment of the tilt angle of the secondary screen 002; two sets of damping assemblies 60 are provided and are symmetrically arranged. First right-angle portions 121 for installing the damping assembly 60 are provided on both sides of the extension portion 12 of the first base 10, and second right-angle portions 42 for installing the damping assembly 60 are provided on both sides of the second base 40. After installation, the two second right-angle portions 42 are located inside the first right-angle portions 121; the damping assembly 60 includes a bolt 61, a first gasket 62, a first damping piece 63, a second gasket 64, a second damping piece 65, and a nut 66. The bolt 61 sequentially passes through the first base 10, the first gasket 62, the second base 40, the first damping piece 63, the second gasket 64, and the second damping piece 65, and is screwed to the nut 66.

[0044] The working principle of the quick disassembly and assembly structure in this embodiment is as follows:

[0045] When the host needs to add or install a sub-screen 002, it is only necessary to embed the locking portion 41 at the upper end of the second base 40 into the slot 021 of the sub-screen 002, and after it fits in place, the second locking piece 50 can be manually tightened to form a semi-finished sub-screen 002, and then the two locking bases 20 on the first base 10 are embedded in the through holes 011 on the vertical pole body 001. After they are in place, the two first locking pieces 30 are tightened to complete the installation of the sub-screen 002. When the sub-screen 002 is damaged due to screen failure and needs to be replaced, it is only necessary to disassemble the two first locking pieces 30 and the second locking pieces 50, or only to loosen the second locking piece 50 to complete the disassembly of the sub-screen 002, and then replace the new sub-screen 002 and reassemble it to quickly complete the repair.
