Abstract
An insert preventing lock comprises a lock body and a lock catch. The lock body is provided with a flexible lock tongue, a safety device and a door knob. A groove is arranged on one side where the lock catch is corresponding to the lock tongue. The key point of the structure is that the lock tongue takes a shape of a solid rectangular; the outer edges of the lock catch groove takes a shape of a slanting. By utilizing solid rectangular lock tongue and under the cooperation of the slanting lock catch groove of the utility model, not only the easy-closing function of the present locks can be realized, but also the function of insert preventing can be added. The utility model solves the technical problem of that the present locks can be forced to open by using articles such as thin card to bunt the lock tongue from the door slot.
Description
[affiliated technical field]
The utility model relates to a kind of spring type door lock.
[background technology]
Existing spring type door lock generally is made up of lock body and snap close.Lock body is installed on the door, and it is made of telescopic dead bolt, safeties, the knob that opens the door etc., and the dead bolt outside is a ramp structure, is convenient to shut the door after you.Snap close is installed on the doorframe, and the dead bolt place has groove relatively, cooperates with dead bolt to reach the purpose of locking a door.But, there is the defective of theftproof performance difference in existing door lock, that is: the user goes out or h.d., if just shut the door after you, and do not use the insurance knob to insure, under external force, as: with thin type card-like article with certain degree of hardness, answer back to dead bolt through crack between a door and its frame, just can oppress dead bolt and make and contract in the dead bolt and, reach the purpose of making a forcible entry into door-lock opening.
[summary of the invention]
Have the deficiency that can not effectively prevent to open through thin type card-like article door lock for solving existing catch-bolt, the utility model provides a kind of Anti-inserting lock of novel structure, has characteristics easy to use, that the anti-plug performance is good.
Task of the present utility model is finished by following technical proposals:
The structure of this Anti-inserting lock comprises lock body and snap close, is equipped with telescopic dead bolt, safeties, the knob that opens the door on the lock body, and the corresponding one side of snap close and dead bolt is provided with the groove for the dead bolt turnover, and its structural feature is: dead bolt is the solid rectangle flat-head shape; Snap close groove outer rim takes the form of inclined plane.
During concrete enforcement, the surface slope of snap close groove outer rim is 45 degree.
Beneficial effect is: the dead bolt of solid rectangle flat-head shape, under the cooperation on groove outer rim inclined-plane, both can realize the existing door lock function easily of closing the door, increased anti-plugging function again newly, solved existing door lock well, with thin type card-like article, answer back to dead bolt through crack between a door and its frame, just can oppress dead bolt and make and contract in the dead bolt and the technical problem of door-lock opening.
[drawing explanation]
Fig. 1 is embodiment perspective view of the utility model.
[specific embodiment]
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
Referring to Fig. 1.Snap close 1 relative dead bolt 4 places offer groove 3, and the outer rim 2 of groove 3 takes the form of inclined plane, and its surface slope can be 45 degree.Lock body 5 is provided with safeties, the knob 7 that opens the door, dead bolt 4, and the safeties that place lock body 5 inside can be realized the location (this structure is consistent with the catch-bolt of prior art) to dead bolt 4 through 6 controls of insurance knob, makes it can not or stretch or contract.Dead bolt 4 is the solid rectangle flat-head shape.During use, when dead bolt 4 revolves when moving to snap close 1 with door, dead bolt 4 at first clashes into the outer rim 2 of groove 3, under ramp effect, contracts in the dead bolt 4, cross this outer rim 2 after, put in the groove 3.Because dead bolt 4 is rectangle stereochemical structures, therefore, thin type card-like article are answered back to dead bolt through crack between a door and its frame, can not apply to make the power that contracts in dead bolt 4 generations, thereby reach the anti-plug purpose.
