Abstract

A door lock guard comprises a lock plug and a combination lock covered on the lock plug, wherein the combination lock includes a combination assembly, a combination, and a lock plate, a mechanical (electronic) combination construction is provided in the combination assembly, a lock plate groove, a lock hole, a offsetting spring, and a screw bolt are provided on the combination lock, the lock plate provided on the lock plate groove provides a lock handle, the lock plate moves driven by the combination and the combination assembly, the lock hole relates to the outer end of the lock plug. Using the lock plate covered on the lock plug and controlled by the combination assembly, the lock plug is protected. When entering the password, the combination assembly moves the lock plate, and then the lock hole and the outer end of the lock plug overlapped, thereby opening the lock and popping the key. Another method is: when entering the password, the combination assembly moves the lock plate, and then the lock hole and the outer end of the lock plug overlapped, thereby opening the lock and popping the key, the combination assembly moves and closes the lock plate to protect the lock plug. So the lock plug is hard to damage.

Description

The door lock bodyguard

Technical field

The utility model relates to the door lock anti-theft technique, is applicable to security door, car door, safety cabinet etc., particularly a kind of door lock bodyguard.

Technical background

The door lock that door lock of selling on the present market and user use mainly is made up of lock panel, lock core, handle, and its shortcoming is that the open-part of lock core is exposed to the outside, and consequently: one, opened door lock by master key easily, its theftproof performance is poor; Two, lock core is filled in foreign material etc. by open-part easily, and is destroyed to cause lock core; Three, key is duplicated by cankered people, and its door just performs practically no function, and makes the people worried, is to have potential safety hazard in a word.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and covers on the lock core, and the protection lock core, it is destroyed that its lock core is difficult for, and theftproof performance is good, safe and reliable door lock bodyguard.

The utility model purpose is achieved in that a kind of door lock bodyguard, comprise password, lock core, it is characterized in that: lock core is coated with coded lock on the outer end, its coded lock is made up of password assembly, password, jam plate, is provided with mechanical cipher structure or electronic cipher structure in the password assembly, and its coded lock is provided with jam plate groove, lockhole, return spring and bolt, the jam plate groove is provided with jam plate, jam plate is provided with the lock handle, by password, password assembly jam plate is moved, and lockhole is corresponding with the lock core outer end.Unclamping the lock handle makes return spring move jam plate door, lock core are covered.

The orientation that described jam plate is installed can be horizontal vertical or oblique, comes and goes to move or rotate to open and close; Can be hidden or expose in the installation site, jam plate is positioned at the top, outer end of lock core.

Described coded lock combines with door by securing member, and password assembly control jam plate moves the protection lock core, and its jam plate can be stealth or exposes.

The utility model is to utilize cipher control password assembly to move the jam plate that covers the lock core outer end, the protection lock core, the operating principle of mechanical cipher is by input cipher control password assembly, mobile jam plate, make lockhole corresponding, can open door lock, withdraw from key with the door lock core outer end, jam plate is closed automatically, again rotational password; Another kind is an electronic cipher, utilizes electronic cipher control password assembly, and mobile jam plate makes lockhole corresponding with lock core, unblanks; move back key, utilize electronic cipher control password assembly again, mobile jam plate is closed; the protection lock core, destroyed thereby door lock core is difficult for, theftproof performance is safe and reliable.
