Description
The utility model is a kind of insurance lockset, is a kind of safety lock that is mainly used in door.
At present, the door lock of used double door generally is structure shown in Figure 1, is fixed with bolt intubate 4 on the door 3, and bolt 2 inserts in the bolt intubate 4, by lock 1 bolt 2 is pinned.This lock structure is fairly simple, but lock 1 in the lockset and bolt 2 all expose, and is vulnerable to sled, pounds or destruction such as sawing, causes stolen.
The purpose of this utility model is a kind of anti-theft safety lock of design, can prevent from effectively the destruction of lock is had antitheft effect.
The designed anti-theft safety lock of the utility model is mainly by guard shield, lock body and bolt constitute, guard shield covers on outside lock body and the bolt, lock body is the padlock of band suspension ring, guard shield comprises lock guard shield and bolt guard shield, lock guard shield and bolt guard shield are corresponding respectively to be installed on every Yishanmen of double door, the lower end of lock guard shield has the opening that lock bodies inserts, have suspension ring corresponding groove on the top wall in the lock guard shield with lock body, the degree of depth of groove is not less than the diameter of suspension ring, the lock guard shield side corresponding with the bolt guard shield has the bolt socket, bolt guard shield chamber internal upper part has the bolt jack, the bottom has chute, also have the bolt socket on bolt guard shield and the lock guard shield corresponding side walls, bolt is positioned at guard shield, insert in the bolt jack, its end that is positioned at guard shield has block, the height of the lockhole that the overall height of this end is made of suspension ring when sealed greater than lock body, the height of lockhole when opening less than lock body, the other end of bolt is outside the bolt jack stretches out the bolt guard shield, this end is fixed with handle, and handle can drive bolt and slide in guard shield.
For strengthening the intensity of bolt, in the bolt of the designed anti-theft safety lock of the utility model, stud with the hard steel bar.
The bolt of the anti-theft safety lock that the utility model is designed is the bolt of external surface through Quenching Treatment.
The guard shield of the anti-theft safety lock that the utility model is designed is the guard shield of external surface through Quenching Treatment.
The length of the bolt of the anti-theft safety lock that the utility model is designed is greater than the length in the lock guard shield chamber and the summation of bolt guard length.
The designed burglary insurance of the utility model is locked in when using, and bolt slides in guard shield, because the block at bolt two ends and the effect of handle can not be separated from the bolt jack.When locking a door, lock body is inserted by the opening part of lock guard shield lower end, the suspension ring of lock body fall into the groove in the lock guard shield, sliding latch, since this moment the bolt front end the height of the lockhole that constitutes less than suspension ring of height by lock body, therefore the bolt front end that has a block enters in the lock guard shield, and passes lockhole.Lock body is sealed, this moment lockhole height less than the overall height of bolt front end, block is blocked by lock body, can not the release lock guard shield, door is lockable.Otherwise, when opening the door, open lock body, just can spur bolt in the other direction, bolt is fallen back in the bolt guard shield, door can be opened.
The advantage of the anti-theft safety lock that the utility model is designed is:
Pick-proof, anti-saw, anti-ly pound high safety.Because lock body and bolt all are positioned at protective cover, be difficult to lock is pried open; With sawing, when destroying bolt, the bolt external surface is high through quenching rear surface hardness, intensity, and studs with the hard steel bar in the bolt, is difficult to sawed-off; After the guard shield external surface quenched, hardness, intensity were higher, are difficult to break, and therefore have stronger theftproof.
2. prevent lock body, bolt corrosion, long service life.Because the protective effect of guard shield, lock body and bolt are difficult for having been prolonged the application life of lockset by water or other material etch.
3. cost is low, and for ease of maintenaince, lock body and bolt are all replaceable.
The designed anti-theft safety lock of the utility model is mainly used on the double door, also can be used on the single door.
