Abstract
The utility model discloses a bidirectional pry-resistant lock catch comprising a lock catch seat. The lock catch seat is internally articulated with a first lock catch and a second lock catch through an articulating shaft; the first lock catch and the second lock catch have the same structure and are reversely overlapped and articulated with the articulating shaft. Both sides of the lock catch seat are respectively provided with the first lock catch and the second lock catch, even though one side of the lock catch seat is pried, the lock catch positioned at the inner side still can lock. A lock of the bidirectional pry-resistant lock catch is in a hook shape with a vertical body and can be prevented from losing antitheft action by separating from a lock hole through prying force; both sides of the lock catch seat are respectively provided with reverse symmetrical lock catches which can not be both pried even though tools; and in addition, the utility model greatly enhances the safety factor and is suitable for various antitheft doors, vault doors and safety box doors.
Description
Technical field
The utility model relates to a kind of pick-proof snap close, relates in particular to a kind of two-way pick-proof snap close that is used for security door, national treasury door and safe door.
Background technology
At present, security door of the prior art, national treasury door and safe door etc. all adopt straight bolt type lock tool that door leaf is fixedlyed connected with doorframe, firm and reliable connection, and security performance is better.But this lockset is to insert in the keyhole on the doorframe and make it to fix by the straight bolt of lockset, if make door leaf shrinkage strain or doorframe distortion, the hole enlarges or use sled power that the gap between door leaf and the doorframe is increased by instrument, the straight bolt of lockset just can withdraw from the doorframe keyhole and door is pried open, thereby loses antitheft effect.
Utility model patent: a kind of pick-proof snap close, the patent No.: 02223322.3 discloses a kind of band pick-proof structure snap close, the outer movable tapered end that comprises the rotation central layer that bolt shaft and eccentric torsionspring are housed, with the interior fixedly tapered end that has dual-mouth structure and the mutual clamping matching of rotation central layer, the pick-proof snap close of folding and locking assembling formation mutually.During its locking, earlier the snap close cap that is provided with on the outer movable tapered end is fastened snap close, then with outer movable tapered end spiral-lock on interior fixedly tapered end, the inclined-plane of dual-mouth structure will rotate central layer automatically and withstand and its rotation is stepped down this moment, two bayonet socket baffle plates on the rotation central layer of last outer movable tapered end are on the contrary by eccentric torsionspring return, block the interior fixedly tapered end that has the dual-mouth structure, finish the snap close locking after, the lock pin of the padlock of will having strong market potential again injects the coordination through hole.During unlatching, pull out lock pin after, entangle the central layer bolt shaft with private key, snap close is opened on inclined-plane that twisting makes the dual-mouth structure and the dislocation of rotation central layer immediately.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of novel structure, two-way pick-proof snap close that safety factor is higher are provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: two-way pick-proof snap close, comprise the snap close seat, and be hinged with first snap close and second snap close by jointed shaft in the snap close seat; First snap close is identical with the structure of second snap close, and oppositely stack is hinged on the jointed shaft.Owing to be provided with first snap close and second snap close respectively in the both sides of snap close seat, even snap close seat one side is prized, still have the snap close of opposite side to pin, improved safety factor greatly.
For optimizing technique scheme, the measure of being taked also comprises:
Above-mentioned snap close seat is spill, and the crossbeam center of snap close seat is provided with the fixedly internal thread hole of locking bar, and two vertical edges of snap close seat are respectively first vertical plate and second vertical plate; First snap close and second snap close are hinged between first vertical plate and second vertical plate of snap close seat.
The first above-mentioned snap close comprises and is hinged on vertically body of first on the jointed shaft that the two ends up and down of the first vertical body are shaped on first tapered end and second tapered end to the same side protrusion respectively.Second snap close comprises and is hinged on vertically body of second on the jointed shaft that the two ends up and down of the second vertical body are shaped on the 3rd tapered end and the 4th tapered end to the same side protrusion respectively.
The hinge hole of first snap close is arranged on the first vertical upper part of body, and the hinge hole of second snap close is arranged on the second vertical upper part of body, and the gap is left respectively and between the crossbeam of snap close seat in the upper end of the upper end of the first vertical body and the second vertical body.
Being subjected to the first spacing snap close of crossbeam and second snap close is 20 ° to 60 ° around the angular range that jointed shaft rotates.
The central axis of first tapered end is an acute angle with the central axis angulation of vertical body.
The lower surface of the lower surface of first vertical plate and second vertical plate constitutes the inclined-plane respectively.
Compared with prior art, the utility model has the advantages that the tapered end of snap close and vertical body are hook-type, can prevent to use sled power to make tapered end break away from lockhole, lose antitheft effect; In the both sides of snap close seat the snap close of reverse symmetry has been installed respectively,, has been improved safety factor greatly even also the snap close of snap close seat both sides all can't be pried open by instrument.
