Description

Technical Field

[0001] This utility model relates to the field of POS machine hinge technology, specifically a POS machine hinge with a protective structure. Background Technology

[0002] A POS terminal is a multi-functional terminal that, when installed at merchant locations and accepted by credit cards and connected to a computer network, enables automatic electronic fund transfers. It supports functions such as purchases, pre-authorization, balance inquiries, and transfers, and is secure, fast, and reliable. In large transactions, basic business intelligence is often difficult to obtain; implementing a POS system primarily addresses information management blind spots in the retail industry. As a crucial component of chain store management information systems, the POS machine reads the cardholder's magnetic stripe information from the 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 transmits this information through the UnionPay center to the issuing bank's system, completing the online transaction, providing success or failure information, and printing the corresponding receipt. The hinge structure is a common feature of POS machines.

[0003] The existing CN111210579B describes a user-friendly POS machine that uses a push-pull plate to move a rack and pinion. The rack and pinion mesh with a gear, which in turn rotates a folding display panel via a pivot. At this point, two button panels are exposed, and the two displays can be bidirectionally displayed after the folding angle of the display panel is adjusted. However, the existing device has shortcomings. The pivot of the device has poor protection and is easily damaged, affecting the rotating structure. Moreover, it is inconvenient to disassemble and replace, resulting in poor performance. Therefore, a POS machine pivot with a protective structure is needed to solve the above problems.

The lower front end of the POS machine 1 has a mounting groove 6, and an operation key is installed on the inner wall of the mounting groove 6. The lower end of the inner wall of the mounting groove 6 of the disc 2 has a rotating slot 15 on both sides, and a rotating plug 16 is inserted into the inner wall of the rotating slot 15. An auxiliary spring 17 is inserted into the front edge of the rotating plug 16, and a lever 18 is fixedly connected to one end of the auxiliary spring 17. A plug shaft 4 is fitted onto the outer wall of one end of the rotating plug 16, and a second telescopic groove 19 is opened at both ends of the plug shaft 4. The plug shaft 4 is inserted into the rotating shaft sleeve groove 12 with a limiting support through a reinforcing shaft 3, and the shape of the reinforcing shaft 3 is matched to the inner wall of the rotating shaft sleeve groove 12. This makes it easy to limit the insertion and disassembly of the plug shaft 4, ensuring stable installation and convenient and quick replacement.

[0021] The insert shaft 4 is installed by interlocking with the rotating slot 15 via the rotating insert block 16. The rotating insert block 16 is elastically telescopically connected to the insert shaft 4 via the second spring 20. The lever block 18 is elastically telescopically connected to the rotating insert block 16 via the auxiliary spring 17. This allows the insert shaft 4 to be easily and easily installed and removed, facilitating overall replacement. The second spring 20 is fixedly connected to the inner wall of the second telescopic groove 19, and one end of the second spring 20 is fixedly connected to one end of the rotating insert block 16. The reinforcing shaft 3 is fixedly connected to the outer wall of the insert shaft 4, and a rotating shaft sleeve groove 12 is fitted onto the outer wall of the reinforcing shaft 3. Protective sleeves 13 are fixedly connected to the edges of both ends of the rotating shaft sleeve groove 12, and a roller 14 is embedded in one end of the protective sleeve 13. The protective sleeve 13 and the rotating insert block 16 are concentrically fitted together, and the protective sleeve 13 is slidably and rotatably connected to the POS machine 1 via the roller 14. This allows the protective sleeve 13 to easily cover and protect the rotating insert block 16, forming a sealed effect and preventing damage.
