Abstract

The utility model relates to an anti-theft lock, which comprises a lock head shell and a lock core. The lock core is sheathed in the lock head shell and is clamped to be fixed by a clamping ring. The tail part of the lock core is connected with a drive piece. The inner of the lock head shell and the lock core is provided with four rows of marbles. The four rows of marbles are arranged in a cross mode. The outer end of the lock head shell is riveted with an anti-drilling sleeve and a protective steel sleeve. The protective steel sleeve is sheathed on the anti-drilling sleeve and is riveted with the lock head shell and the anti-drilling sleeve. The outer end surface of the lock core is limited with an anti-drilling fixing piece by a fixing nail which is arranged on the outer end surface. An anti-drilling moving piece is lapped on the anti-drilling fixing piece and is sheathed by the anti-drilling sleeve. The anti-drilling moving piece can free rotate. The utility model has a draw resistance function, a twisting and pulling resistance function, a drilling resstance function, a prying resistance function, a technical opening resistance function, etc.

Description

A kind of anti-theft lock end

The utility model relates to a kind of tapered end, particularly relates to a kind of tapered end of fitted outside lock.

The tapered end of existing fitted outside lock does not possess anti-drawing function basically, and function anti-drilling, pick-proof is also relatively poor, can not satisfy the antitheft requirement of an installation.

The purpose of this utility model is to provide a kind of anti-theft lock end with fitted outside lock of multiple functions such as anti-drawing, anti-drilling, pick-proof.

For reaching above-mentioned purpose, the anti-theft lock end that the utility model provides comprises tapered end shell and lock core, lock core be enclosed within block with snap ring in the tapered end shell fixing, the afterbody of lock core is connected with a driver blade, is provided with four row's pellets shot from a slingshot in tapered end shell and the lock core, and four row's pellets shot from a slingshot are right-angled intersection and arrange; The riveted joint of described tapered end shell outer end has anti-drill bushing and protection steel bushing, and the protection steel bushing entangles anti-drill bushing and rivets mutually with tapered end shell and anti-drill bushing; Described lock core outer face is limited with an anti-drilling stator by the staple that makes on it, and anti-drilling moving plate rides on the anti-drilling stator and by anti-drilling cover and entangles, and anti-drilling moving plate is free to rotate.This structure, when tapered end being contained in be subjected on the door external powerful drawing, the protection steel bushing comes off, and anti-drill bushing is still firm, thus protected anti-drilling sheet, tapered end because of destroying, is not unlocked in drawing.Adopt the dual anti-drilling sheet structure of anti-drilling moving plate and anti-drilling stator, also have tamper-resistant function when making tapered end possess anti-drilling function.

Advance a kind of improvement as of the present utility model, described lock core outer end is provided with the anti-drilling steel nail of a hard, can effectively stop the brill to the tapered end pellet shot from a slingshot to break up bad like this; Keyhole on the described lock core is a blind hole at the lock core afterbody, opens lock to prevent that foreign matter from instigateeing driver blade by keyhole; Be provided with at least one rejection shape pellet shot from a slingshot in described four row's pellets shot from a slingshot, special-shaped pellet shot from a slingshot middle part is provided with an annular groove, strengthens the ability of anti-technical unlocking with this; Described tapered end shell periphery is incomplete circle, which is provided with a breach and tapered end be provided with one with the couplet on the door connect fixing connector, connector comprises screw and pressing plate, pressing plate is fixed on the door, screw passes pressing plate and the tapered end shell spins fixing, these structures can be stabilized on the door tapered end, prevent the external powerful destruction of pull out force to tapered end of turning round.

In sum, the utlity model has anti-drawing, anti-turn round pull out, functions such as anti-drilling, pick-proof and anti-technical unlocking.

Below in conjunction with drawings and Examples structure of the present utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is along the sectional view of A-A line among Fig. 1;

Fig. 3 is along the sectional view of B-B line among Fig. 1;

Fig. 4 is the structural representation of special-shaped pellet shot from a slingshot described in the utility model.

As shown in the figure, the utility model anti-theft lock end comprises tapered end shell 1 and lock core 2, and tapered end shell 1 periphery is incomplete circle, which is provided with a breach 14; Lock core 2 is enclosed within and blocks fixingly in the tapered end shell 1 with snap ring 3, and the afterbody of lock core 2 is connected with a driver blade 4.Be provided with four row's pellets shot from a slingshot 5, four row pellets shot from a slingshot 5 in tapered end shell 1 and the lock core 2 and be right-angled intersection and arrange, be provided with in four row's pellets shot from a slingshot 5 a rejection shape pellet shot from a slingshot 5 ', special-shaped pellet shot from a slingshot 5 ' middle part is provided with an annular groove 13.There is anti-drill bushing 6 tapered end shell 1 outer end with 17 riveted joints of hard rivet, with soft rivet 18 riveted joints protection steel bushing 7 is arranged, and protection steel bushing 7 entangles anti-drill bushing 6 and rivets mutually with tapered end shell 1 and anti-drill bushing 6.Lock core 2 outer faces are limited with an anti-drilling stator 9 by the staple 8 that makes on it, and anti-drilling moving plate 10 rides on the anti-drilling stator 9 and by anti-drill bushing 6 and entangles, and anti-drilling moving plate 10 is free to rotate.Lock core 2 outer ends also are provided with the anti-drilling steel nail 11 of a hard.Keyhole 12 on the lock core 2 of the present utility model is designed to blind hole at the lock core afterbody.

The utility model lock is provided with a tapered end and the couplet on the door connects fixing connector, and connector comprises screw 15 and pressing plate 16, and pressing plate 16 is fixed on the door, which is provided with three screw holes and a transmission film perforation, and screw 15 passes pressing plate 16 and spins fixing with tapered end shell 1.
