Description

Technical Field

[0001] This utility model relates to the field of POS machine technology, specifically to a retractable wall-mounted POS machine. Background Technology

[0002] A POS machine reads the cardholder's magnetic stripe information from a bank card using a card reader. The POS operator enters the transaction amount, and the cardholder enters their personal identification information (i.e., PIN). The POS then sends this information to the issuing bank's system through the UnionPay center to complete the online transaction, providing a success or failure message and printing the corresponding receipt.

[0003] Currently, POS machines are usually placed on a table or counter during use. Although this conforms to conventional operating habits, they are easily affected by the external environment. For example, POS machines that are exposed to the table for a long time are prone to dust accumulation and moisture. Especially in high humidity scenarios such as catering, food residue and beverage spills may seep into the machine and cause circuit failures. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This application provides a retractable wall-mounted POS machine, which solves the problems in the prior art.

[0028] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0029] like Figures 1-6 As shown, a retractable wall-mounted POS machine includes:

[0030] The outer casing 7 has four mounting bases 6 connected to its back side. A sealing plate 2 is slidably connected to the left side of the outer casing 7. A back plate 8 is connected to the inner side of the sealing plate 2. A pair of first through holes 10 and a pair of second through holes 18 are respectively opened on the front and rear sides of the back plate 8. The positions of the first through holes 10 and the second through holes 18 correspond to the positions of the second through holes 18. A pair of L-shaped hanging plates 15 are symmetrically connected inside the pair of second through holes 18. An elastic mechanism is provided inside the L-shaped hanging plates 15.

[0031] A pair of L-shaped mounting plates 15 are fitted with U-shaped plates 14 on their outer sides, and the outer side of the U-shaped plates 14 is connected to the POS machine body 3.

[0032] In some examples, the elastic mechanism includes a partition 19, with a pair of connecting rods 16 connected to both the upper and lower sides of the partition 19. One end of each pair of connecting rods 16 passes through the interior of the L-shaped hanging plate 15 and is fixedly connected to the inner wall of the back plate 8. A return spring 17 is sleeved on the outside of the connecting rods 16. One end of the return spring 17 is fixedly connected to the partition 19, and the other end of the return spring 17 is fixedly connected to the L-shaped hanging plate 15.

[0033] In some examples, the inner side of the L-shaped hanging plate 15 is connected to a lever 9, which passes through the interior of the first through hole 10. When the POS machine body 3 needs to be taken out for use, the sealing plate 2 is pulled out, and then the levers 9 on both sides are pressed to drive the L-shaped hanging plates 15 on both sides to move towards each other, so that the L-shaped hanging plate 15 can be easily taken out from the U-shaped plate 14 on the back side of the POS machine body 3, and then the POS machine body 3 can be removed. Conversely, when the POS machine body 3 needs to be stored, the levers 9 on both sides are pressed to easily hang the U-shaped plate 14 on the back side on the L-shaped hanging plate 15. Then the levers 9 are released, and the elastic return effect of the return spring 17 is used to easily hang the POS machine body 3 on the L-shaped hanging plate 15, thus achieving the storage effect.

[0034] In some examples, a pair of side plates 11 are connected to the outer side of the sealing plate 2, a pair of guide rods 4 are connected to the inner side of the side plates 11, and a guide sleeve 5 is slidably connected to the outer side of the guide rods 4. The guide sleeve 5 is fixedly connected to the outer shell 7. The connection between the guide rods 4 and the guide sleeve 5 facilitates the sliding of the sealing plate 2.

[0035] In some examples, a groove 13 is provided on the outer side of the guide rod 4, and a limiting block 12 is slidably connected inside the groove 13. One side of the limiting block 12 is fixedly connected to the outer shell 7. Under the limiting action of the limiting block 12, the guide rod 4 is effectively limited, preventing the guide rod 4 from sliding out of the inside of the guide sleeve 5.

[0036] In some examples, a magnetic absorbing sheet 1 is connected to the inner side of the sealing plate 2, and a magnetic absorbing plate 20 is connected to the left side of the outer casing 7 near the magnetic absorbing sheet 1. By setting the magnetic absorbing sheet 1 and the magnetic absorbing plate 20, it is convenient to seal the sealing plate 2 and the outer casing 7 and avoid the influence of the external environment.

[0037] This utility model features four mounting bases 6 on the back side of the outer casing 7, with expansion screws installed inside each mounting base 6, facilitating the fixing of the outer casing 7 to the wall. When the POS machine body 3 needs to be removed for use, the sealing plate 2 is pulled out, and then the levers 9 on both sides are pressed to drive the L-shaped hanging plates 15 on both sides to move towards each other, thus facilitating the removal of the L-shaped hanging plates 15 from the U-shaped plate 14 on the back side of the POS machine body 3, allowing the POS machine body 3 to be removed. Conversely, when the POS machine body 3 needs to be stored, the levers 9 on both sides are pressed to hang the U-shaped plate 14 on the back side onto the L-shaped hanging plate 15, and then the levers 9 are released. Utilizing the elastic return effect of the return spring 17, the POS machine body 3 is easily hung on the L-shaped hanging plate 15, achieving a storage effect and avoiding the influence of the external environment.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
