Description
Technical field
The present invention relates to a kind of hardware locksets, and in particular to a kind of explosion-proof transmission mechanism of door lock.
Background technique
The antitheft explosion-proof technology of existing door lock all has certain limitation currently on the market, and general use reinforces door
Structure or external some antitheft anti-explosion mechanisms are antitheft explosion-proof to achieve the effect that using explosion-proof lock core structure and in lock body, still
Door lock can still be opened when lock core is integrally destroyed or lock body large area is destroyed.
The applicant has found after having done a large amount of investigation, generally when violence damage is opened the door, often all only to lock core or
Person's door shell part is destroyed, this two parts is destroyed, and one, which turns the handle, to open the door, on door knob hand position, by
In the use habit the problem of, most of all habits are opened the door with door handle, therefore will not all be destroyed to door handle.
Summary of the invention
The present invention in view of the above problems, provides a kind of delicate structure in door knob hand position, easy to use, tool
There is the transmission mechanism of explosion prevention function.
Technical solution used by the present invention solves the above problems is:
A kind of new type explosion proof transmission mechanism, including door lock ontology, the door lock ontology are equipped with transmission mechanism and lock tongue machine
Structure, the transmission mechanism are arranged in the middle part of spring bolt mechanism, and the transmission mechanism includes a shifting block mechanism and linkage mechanism, and described group
Block mechanism includes leader's seat, and the handle base is equipped with switch block, and the switch block is equipped with pusher dog, and the linkage mechanism includes one
Linkage board, the linkage board lower section are equipped with lock core thumb wheel, are additionally provided with limit base between the linkage board and handle base.
Further, the switch block is equipped with several through-holes, is equipped with short slot, the handle base upper end in the middle part of the handle base
Lead to the hole site is corresponded to limit base side equipped with slot.
Further, it is equipped with pushing block in the short slot, spring is equipped between the pushing block both ends and handle base, it is described to push away
Solution closing piece is equipped between block and through-hole, the solution closing piece includes a lock pillar, and the lock pillar front end is equipped with an idler wheel.
The design that closing piece front end uses idler wheel is solved, the frictional force of linkage board reconciliation closing piece is greatly reduced, to increase
The service life used.
Further, elastic component is equipped in the slot, the elastic component front end is equipped with steel ball.
Further, the corresponding linkage Board position of the limit base is additionally provided with limiting slot.
Linkage board and limit base are used cooperatively, and allow linkage board unlock can be pushed into correct position fastly, to reach unlock
Purpose of the door handle to open the door.
It can be seen from the above technical scheme that the invention has the advantages that
1. the lock core when door lock is destroyed, since lock core is not available, handle base still can not rotate unlock, due to tradition
Use habit, allow saboteur to take for not unlocking, to achieve the purpose that explosion-proof unlocking；
2. present invention manufacture is easy, easy to assembly, stable structure is durable.
Other than objects, features and advantages described above, there are also other objects, features and advantages by the present invention.
Below with reference to figure, the present invention is described in further detail.
