Inhibit each other type safe multi-drawer locking mechanism

Abstract

The invention relates to an interacted safe multi-drawer locking mechanism, which consists of a mounting support containing a main soleplate, a top plate, a bottom soleplate, a limit cover plate and a bending retaining piece, a driving mechanism containing an L-shaped bed plate, a lock catch board, a shaft pin and a compression spring, an alternative typed actuator containing a main shaft and a plurality of shaft sleeve subassembly groups and a fully locking actuator containing a lock bar, a fixed locking plate and a sliding locking plate. The length of the main shaft is set to be equal to the total length of all the shaft sleeves plus the height of an inclined plane of a rotatable shaft sleeve, and only a clearance which allows one rotatable shaft sleeve to rotate is exist, therefore only one drawer can be opened at one time; when the lock bar controls the cylinder to block the clearance, all the drawers can be locked. The invention has strong adaptability to working environment as no other drawer can be opened at the same time when one drawer is opened.

Description

technical field [0001] The invention relates to a mechanical locking device, in particular to a mutually restrictive safety multi-drawer locking mechanism which has the function of uniformly locking all drawers but can only open one drawer at a time when in use. Background technique [0002] The current multi-drawer locking mechanism only has the function of locking all drawers and unlocking all drawers at the same time. When taking parts from the drawer, all the drawers are in an unlocked and openable state, so there is a lot of mutual interference, and multiple drawers are prone to occur. In the case of sliding out at the same time, especially for multi-drawer toolbox cabinets working in a vibrating or shaking environment, the operator must be very careful when performing the task of opening and picking, otherwise it is easy to cause multiple drawers to slide out at the same time and the toolbox cabinet will be lost.

[0002] The current multi-drawer locking mechanism only has the function of locking all drawers and unlocking all drawers at the same time. When taking parts from the drawer, all the drawers are in an unlocked and openable state, so there is a lot of mutual interference, and multiple drawers are prone to occur. In the case of sliding out at the same time, especially for multi-drawer toolbox cabinets working in a vibrating or shaking environment, the operator must be very careful when performing the task of opening and picking, otherwise it is easy to cause multiple drawers to slide out at the same time and the toolbox cabinet will be lost. The center of gravity, the unbearable situation or safety accident caused by dumping and spilling tools on the ground

Therefore, the structure of the multi-drawer locking mechanism in the prior art is unreasonable, and it is necessary to improve it.
