A card reader fixing device

Abstract

The invention discloses a fixing device for a card reader, which includes a fixing seat with a through hole in the middle and a support rod placed in the through hole, the fixing seat is provided with an annular protrusion, and the outer wall of the annular protrusion is provided with threads. The rotating cylinder is set on the annular protrusion through thread rotation, and also includes a plurality of fixed blocks, which are arranged on the inner wall of the rotating cylinder, and the end of the fixed block is hinged with an L-shaped clamping block, which clamps The side of the block is connected with the inner wall of the rotating cylinder through a spring, and a plurality of protrusions matched with the clamping block are arranged on the outer wall of the support rod. There is also a spring between the L-shaped clamping block and the inner wall of the rotating cylinder. During driving, especially on bumpy roads, when the vehicle body shakes violently, the connection between the clamping block and the protrusion will appear certain. Vibration, the spring can eliminate the stress generated by the vibration through compression deformation, so as to ensure the stable connection of the fixing seat on the support rod, and then ensure the stable operation of the card reader on the support rod.

Description

It is composed of a vehicle toll terminal and a background management system, which greatly improves the service ...

AI Technical Summary

Problems solved by technology

During driving, especially on bumpy roads, the body shakes violently, which makes the fixing of the card reader easy to loosen, which in turn leads to damage or direct failure of the card reader; and the existing card reader is fixed by welding or clamps. , when replacing or repairing the credit card machine, it can only be dismantled by cutting or violent destruction, resulting in a large waste of materials
