AI Technical Summary

Technical Problem

The existing pluggable force detection devices are prone to inaccurate data due to slippage during the detection process, and the relative displacement difference cannot be detected in time, resulting in less obvious deviations.

Method used

A tool for inserting and pulling force detection of the automotive headrest guide case including a clamping pulling unit, an anti-slip alarm unit, an offset indicator unit and an unlocking unit is designed, and the structures are carried out by friction wheels, cams, synchronization plates, rocker arms and torsion springs. , realize anti-slip alarm and offset indication to ensure the accuracy and safety of the detection data.

Benefits of technology

It effectively prevents errors in the detection device when the headrest and equipment slip. Through the automatic alarm and offset indication functions, the accuracy and safety of plug-and-removal force detection are ensured, and useless detection is reduced.

Abstract

The present invention relates to the technical field of plug-in and pull-out force detection, and discloses a plug-in and pull-out force detection tool for a car headrest guide sleeve, comprising a clamping and pulling unit, an anti-skid alarm unit, an offset indication unit and an unlocking unit. The anti-skid alarm unit of the present invention can ensure that when the headrest and the detection device slip, the friction wheel rotates, and then the friction wheel can drive the coaxially connected cam to rotate, the cam squeezes the pressure plate to slide horizontally, and then drives the bottom vertical plate and the synchronous plate to approach the center, the rocker arm on the synchronous plate can drive the slide plate to slide vertically upward, the knocking rod on the slide plate can always slide along the fixed plate, and when the knocking rod slides on the guide block, the second torsion spring is twisted at this time, and then the purpose of accumulating force is achieved. When the knocking rod moves to the sound board, the second torsion spring is used to unload the force, so that the knocking rod accelerates to knock the sound board, and then the purpose of alarm is achieved, ensuring that when sliding dislocation occurs, the device can automatically alarm.
