Locking mechanism with double safety function

By designing a locking mechanism with dual insurance functions, the first limiting component detects the installation status, and the second limiting component works in conjunction with the rotating handle. This solves the risks of mis-locking and improper installation that are common in traditional locking mechanisms, and achieves a safe and reliable connection of modular components.

AI Technical Summary

Technical Problem

Traditional quick-locking mechanisms pose safety risks such as accidental unlocking and failure to install properly without prior inspection, which could lead to the risk of modular components accidentally falling off or separating.

Method used

Design a locking mechanism with dual insurance function. The first limiting component detects whether the modular component is installed in place, and the second limiting component cooperates with the rotating handle to unlock, avoiding accidental contact or accidental rotation to unlock, thus forming dual insurance in the installation and unlocking stages.

Benefits of technology

It achieves a dual-security function during the installation and unlocking phases, avoiding situations where modular components are not properly installed before locking or mis-locking, thus improving safety and reliability.

Abstract

The utility model belongs to locking mechanism technical field, concretely relates to a locking mechanism with double insurance function, the utility model includes: main body and with the lock bar of main body sliding connection, first limit component is set in the main body for limiting lock bar movement, rotating handle is rotatably connected with the main body, its side surface is linked with lock bar, wherein the rotating handle is suitable for moving lock bar up and down when rotating, second limit component is set in the rotating handle for limiting rotating handle rotation, this locking mechanism with double insurance function is through setting first limit component to detect whether modular assembly is installed in place, avoids locking the modular assembly that is not installed in place, realizes unlocking through the cooperation of second limit component and rotating handle rotation, avoids the situation that unlocking can be realized if second limit component is separately touched mistakenly or rotating handle is rotated mistakenly, thereby reaches the effect that the double insurance function of realizing installation insurance and unlocking insurance.
