Description

Novel explosion-proof transmission mechanism

Technical Field

The utility model relates to a five metals tool to lock, concretely relates to explosion-proof drive mechanism for lock.

Background

The anti-theft and anti-explosion technology of the existing door lock in the current market has certain limitation, generally adopts a structure of a reinforced door or adopts an anti-explosion lock cylinder structure and a plurality of anti-theft and anti-explosion mechanisms arranged inside and outside a lock body to achieve the anti-theft and anti-explosion effects, but once the whole lock cylinder is damaged or the lock body is damaged in a large area, the door lock can still be opened.

After a great deal of investigation, the applicant finds that generally, when the door is opened by violent damage, the lock core or the door lock shell part is usually only damaged, the two parts are damaged, the door can be opened by rotating the door handle, and in the position of the door handle, most of the door handles are used to open the door by the door handle due to the problem of use habit, so that the door handle cannot be damaged.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the problem that above-mentioned exists, provide a structure that uses at the door handle position is exquisite, convenient to use, has explosion-proof function's drive mechanism.

The utility model provides a technical scheme that above-mentioned problem adopted is:

the utility model provides a novel explosion-proof drive mechanism, includes the lock body, be equipped with drive mechanism and spring bolt mechanism on the lock body, drive mechanism sets up at the spring bolt mechanism middle part, drive mechanism includes a shifting block mechanism and link gear, shifting block mechanism includes a handle seat, be equipped with the turning block on the handle seat, be equipped with the pusher dog on the turning block, link gear includes a linkage board, linkage board below is equipped with the lock core thumb wheel, still be equipped with spacing seat between linkage board and the handle seat.

Furthermore, a plurality of through holes are formed in the rotating block, a notch is formed in the middle of the handle seat, and slots are formed in the positions, corresponding to the through holes, of the upper end of the handle seat and one side of the limiting seat.

Furthermore, a pushing block is arranged in the notch, a spring is arranged between the two ends of the pushing block and the handle seat, an unlocking block is arranged between the pushing block and the through hole and comprises a locking column, and a roller is arranged at the front end of the locking column.

The front end of the unlocking block adopts the design of the roller, so that the friction force of the linkage plate and the unlocking block is greatly reduced, and the service life is prolonged.

Furthermore, an elastic piece is arranged in the slot, and a steel ball is arranged at the front end of the elastic piece.

Furthermore, a limiting groove is formed in the position, corresponding to the linkage plate, of the limiting seat.

The linkage plate and the limiting seat are matched for use, so that the linkage plate can quickly push the unlocking to a correct position, and the purpose of unlocking the door handle to open the door is achieved.

According to the above technical solution, the utility model has the advantages that:

1. when the lock cylinder of the door lock is damaged, the handle seat still cannot be rotated to unlock due to the fact that the lock cylinder cannot be used, and a destroyer mistakenly thinks that unlocking cannot be performed due to the traditional use habit, so that the aim of explosion-proof unlocking is fulfilled;

2. the utility model discloses it is easy to make, and the equipment is convenient, stable in structure, durable.

In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be described in further detail with reference to the drawings.
