Description

Technical Field

[0001] This utility model relates to the field of cash register technology, and in particular to a dual-screen cash register with multi-angle adjustment. Background Technology

[0002] In offline consumption scenarios such as retail, catering, and supermarkets, POS devices serve as the core terminal for transaction settlement, and their performance and user experience directly affect the operational efficiency of merchants and customer satisfaction.

[0003] Current POS machines use a dual-screen design, with one screen for cashier operation and the other for customers to view checkout data. While these dual-screen POS machines offer adjustable vertical and horizontal angles, the following issues still exist in actual use: While the current client-side screen can be adjusted up, down, left, and right, the height adjustment still relies on a phased adjustment method using latches. This method is not flexible enough and is inconvenient to operate, requiring repeated insertion and removal of latches. Additionally, the client-side screen cannot be rotated, preventing the adoption of widescreen or narrowscreen modes based on actual application scenarios. Utility Model Content

[0028] In summary, this utility model, through the snap-fit ​​connection between the ratchet assembly 64 and the ratchet rack 63, can effectively adjust and fix the lifting height of the sliding square tube 62. The inclined surface of the ratchet 643 in the ratchet assembly 64 and the inclined surface of the tooth groove in the ratchet rack 63 guide each other, automatically pushing the ratchet 643 open. The torsion spring then drives the ratchet 643 to automatically snap into the ratchet rack 63, achieving automatic snap-fit ​​fixation. The dense tooth groove snap-fit ​​of the ratchet rack 63 reduces the stages of adjustment and improves the flexibility of adjustment. The mutual rotation of the connecting column 91 and the connecting sleeve 95 allows the sub-screen 7 to flip horizontally, thereby controlling the sub-screen 7 to rotate to a vertical or horizontal position. After adjustment, the thrust spring 94 pushes the sliding ball 93 to snap into the locking hole 96, achieving compression fixation. By adjusting for vertical and horizontal positions, it can adapt to different application scenarios.
