Description

Technical Field

[0001] The utility model relates to the technical field of POS machines, in particular to a key protection structure of a POS machine. Background Art

[0002] A POS machine is a terminal reader equipped with barcode or OCR code technology, with cash or barter cashier functions. The main task of a POS is to provide data services and management functions for commodity and media transactions, and to conduct non-cash settlements. It can also realize automatic electronic fund transfers, and has functions of supporting consumption, pre-authorization, and balance inquiries. The surfaces of existing POS machine buttons are easily worn out after long-term use, so the numbers on them cannot be seen clearly and it is easy to press the wrong button. In addition, there is a gap between the button position and the POS machine casing. These gaps increase after being pressed, making it easy for dust to enter, resulting in malfunctioning buttons and making it more troublesome to use. Utility Model Content

[0011] 1. The utility model cooperates with a chassis, a dual-axis motor, a threaded rod, a threaded sleeve, a limit sleeve, a sliding rod, a connecting rod, a second magnet, a third magnet and a protective cover. The output shaft of the dual-axis motor drives the limit sleeve to move through the threaded rod and the threaded sleeve, and the limit sleeve drives the protective cover to move through the sliding rod and the connecting rod. When the threaded sleeve moves to the outside, the second magnet and the fourth magnet attract each other, so that the protective cover moves to the outside. When the threaded sleeve moves to the middle, the first magnet and the third magnet attract each other, so that the sealing effect of the protective cover is good, thereby achieving a high practicality effect and solving the problem of low practicality of the existing device.

[0012] 2. The utility model facilitates limiting the threaded sleeve by cooperating with the limiting rod and the limiting groove, and facilitates moving the two threaded sleeves toward each other by designing the threads on the surfaces of the two threaded rods to be in opposite directions.
