AI Technical Summary

Technical Problem

Traditional POS machines lack impact resistance and rely heavily on a single outer shell material for cushioning. They lack a tiered force-dissipating structure, making critical internal components susceptible to rigid impact damage when dropped or collided.

Method used

A POS machine security protection terminal with a built-in security zone was designed. It adopts a graded force-dissipating structure, including components such as inner rods, outer rods, springs and rubber rings. The multi-level buffer components absorb impact energy and prevent the impact force from being directly transmitted to internal components.

Benefits of technology

It effectively reduces the impact of impact on internal precision components, improves the equipment's impact resistance and service life, and ensures the safety of critical components.

Abstract

The utility model relates to POS machine related technical field especially, POS machine safety protection terminal of built -in safety area, including terminal upper cover, the upper end of terminal upper cover is provided with terminal lower cover, the lower fixed mounting of terminal lower cover has the inner layer rod, both ends of the inner layer rod all fixed mounting have first sliding block, the outer ring of inner layer rod is equipped with first spring, when the equipment encounters drop, the collision etc. longitudinal impact force, the force will drive the inner layer rod of terminal lower cover connection and move downward, first sliding block of the both ends of inner layer rod slides along the slide groove of outer layer rod inside stably at this moment, avoids the motion deflection, the first spring of inner layer rod outer cover is compressed synchronously, through the elastic deformation preliminary absorption impact energy, when the lower end of inner layer rod contacts the rubber ring, the rubber ring of interference fit utilizes the elasticity further to buffer the force, and this kind of grading force design avoids the rigid impact transmission of traditional single shell buffer, can effectively reduce the influence of impact force to internal precision component.
