Summary of the invention:
Goal of the invention of the present invention is to provide a kind of can prevent more effectively that the robber from destroying security door door lock security door, that theftproof performance is good through destroying lock core.
The present invention realizes like this; Comprise the lock body that is arranged in antitheft every body, the handle mechanism that is arranged on the lock body both sides; Lock body comprises dead bolt part, drives the lock core part and the drive link of the dead bolt action of dead bolt part, and the two ends of drive link are connected in the handle connecting hole of two handle mechanisms, and dead bolt comprises that partly strip installs and fixes panel, is fixed on strip and installs and fixes the dead bolt mechanical movement part on the panel; Lock core partly is arranged on the dead bolt mechanical movement part; The lock core of lock core part is perpendicular to the dead bolt of dead bolt mechanical movement part, and drive link is vertically set on the dead bolt mechanical movement part, and its special feature is between the Men Tiyu lock body, to be provided with the protection steel plate that is fixed in antitheft every body; Lateral surface at the protection steel plate is provided with the anti-drilling locking closure that has the lock core perforation; The protection steel plate of corresponding lock core perforation is provided with perforation, between anti-drilling locking closure and protection steel plate, rotates and is provided with anti-drilling rotor, is fixed with the tapered end protective sleeve in protection steel plate inboard; The tapered end protective sleeve is provided with the tapered end perforation that matches with lock core tapered end shape partly; Lock core perforation, perforation, tapered end perforation are positioned on the same axis, and the steel plate that anti-drilling locking closure passes antitheft every body is fixed on the protection steel plate, and the keyhole that is fixed on the handle mechanism of the external side of antitheft every faces toward the lock core perforation of anti-drilling locking closure.During use, key passes the keyhole of handle mechanism, stirs anti-drilling rotor, so that expose lock core keyhole, then key is injected the lock core that drives the lock core part in the keyhole and rotates, and drives the dead bolt action of dead bolt part, carries out the switch door.Owing to adopted protection steel plate and tapered end protective sleeve, like this,, can not damage the lock core of lock core part, thereby protect security door effectively even the robber has destroyed the perforation on antitheft every body, improved the theftproof performance of security door.
For the dead bolt part is fixed in antitheft every body more firmly; Prevent that the robber from concerning and destroy security door through destroying position accurately between dead bolt part and protection steel plate; One at vertical protection steel plate is provided with dead bolt partial fixing riser; The strip of dead bolt part installs and fixes panel and is provided with boss; The dead bolt partial fixing riser of corresponding boss is provided with wears mouth, and the boss that strip installs and fixes panel passes from the inboard mouthful and bar shaped is installed and fixed panel is fixed on the dead bolt partial fixing riser through pierce into screw that strip installs and fixes the panel two ends from the outside.Adopt dead bolt partial fixing riser and install and fix panel at strip to be provided with boss, under the effect of the location of the vertical direction of lock core part, the dead bolt part just can not be taken out from the set mouth of wearing on the fixing riser.The strip of prior art installs and fixes the outside that panel is arranged on antitheft every body side surface, and the robber will adopt and steal the technology of colluding and make dead bolt part wearing from antitheft every body along antitheft every body side surface mouthful collude the moving lock tongue portion outward and then reach the purpose of destroying security door.Adopt technology of the present invention just to efficiently solve the existing problem of prior art.
Compared with present technology the present invention has and can prevent more effectively that the robber from destroying advantage security door, that theftproof performance is good through destroying lock core.
