Non-hooked prevention type touching and locking mechanism

Abstract

A non-hooked prevention type touching and locking mechanism comprises a triggering base and a locking and triggering box body, wherein the triggering base is in sliding fit with the locking and triggering box body. The triggering base is provided with an oblique plane in the door closing direction, the locking and triggering box body comprises triggering hook idler wheels, a triggering idler wheel, a triggering rod connected with the triggering idler wheel in a sliding mode, a locking rod and a locking idler wheel, a limiting rod is arranged between the triggering rod and a triggering hook connecting rod, the bottom of the limiting rod leans on a compressed spring and is connected with the triggering base, and a raising rod is arranged on the top of the limiting rod; when the triggering hook is in sliding fit with the locking idler wheel, the raising rod is in sliding fit with a triggering hook butting mechanism. According to the mechanism, the limiting rod is added, the situation that two critical states including hooking and disengagement of the locking idler wheel and the triggering hook and sliding into and disengagement of the triggering hook idler wheels and the triggering base exist is avoided, the situation that the locking idler wheel on the triggering hook and the locking rod is not hooked is avoided, performance of the touching and locking mechanism is improved, and locking is firmer and more reliable.

Description

technical field [0001] The invention relates to a door lock mechanism, in particular to an unhooked anti-touch locking mechanism. Background technique [0002] The slide-in locking mechanism is one of the ways to meet the heavy load mechanical lock. One of the currently commonly used slide-in locking mechanisms is that the slide-in mechanism and the touch mechanism are connected by a rigid rod or a steel rope. In this structure, the slide-in mechanism and the touch mechanism are not integrated, and the linkage between the rigid connecting rod or the steel rope Affects the motion of the slide-in mechanism. One is that the sliding mechanism is integrated with the touch mechanism. This structure relies on the linkage between the trigger hook and the locking roller hook on the locking lever to realize unlocking and locking. In actual operation, the trigger hook and the locking roller on the locking lever The situation of not hooking often occurs, causing unblanking or locking ...

Problems solved by technology

One of the currently commonly used slide-in locking mechanisms is that the slide-in mechanism and the touch mechanism are connected by a rigid rod or a steel rope. In this structure, the slide-in mechanism and the touch mechanism are not integrated, and the linkage between the rigid connecting rod or the steel rope Affects the motion of the slide-in mechanism

One is that the sliding mechanism is integrated with the touch mechanism. This structure relies on the linkage between the trigger hook and the locking roller hook on the locking lever to realize unlocking and locking. In actual operation, the trigger hook and the locking roller on the locking lever There will often be a situation where the hook is not hooked, resulting in failure to unlock or lock, causing a lot of inconvenience to the user when closing the locking mechanism

Therefore, the slide-in touch locks of the above two methods do not prevent the hook device from being unlocked, resulting in low performance of this type of slide-in touch lock, which causes a lot of inconvenience to the user when closing the locking mechanism.
