Description

The intelligent anti-theft safety lock

Technical field

The utility model belongs to a kind of coded lock.

Background technology

There is following outstanding problem in the configuration of used theftproof lock and lockset on the existing security door: 1. the ability of anti-" technical opening " is low.The lock body structure of common spring lock is too simple, and the pellet shot from a slingshot that only needs to play the pin effect is pressed in the duct of core body, and mandrel just can rotate, and withdraws from from the door bolt hole of doorframe thereby drive dead bolt or pull bar drive lock bolt again, so just door can be opened.2. the unreasonable allocation of lockset on door.In order to increase " technical opening " time that security door is locked, now many producers have adopted the scheme of two locks of separate configurations, but this allocation plan does not tackle the problem at its root, can only be to have made " technical opening " time lengthening of only adorning a lock one times, this can not effectively solve the antitheft problem of door lock.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-" technical opening " ability strong, and it is more reasonable to dispose, the intelligent anti-theft safety lock that cost performance is more excellent.

The technical solution of the utility model is as follows: a kind of intelligent anti-theft safety lock, comprise lock and place the interior lock core of lock, the pull bar that is used for spurring bolt passes from locking closure, be fixed with block on the pull bar, the mandrel bottom axle of lock core is flat to be connected with a drive screw, the outside of lock is set with the sliding sleeve with arm with two transverse arms, the center screw of sliding sleeve with arm and the interlock mutually of the screw thread of drive screw, the top of sliding sleeve with arm is provided with lead, lead embeds in the vertical transverse arm of sliding sleeve with arm, and sliding sleeve with arm can move horizontally with the rotation of drive screw.

Aforesaid intelligent anti-theft safety lock, wherein, the horizontal cross-arm of sliding sleeve with arm is provided with key, and block is provided with suitable with it keyway, and when key and keyway aligned, pull bar can move down.

Aforesaid intelligent anti-theft safety lock, wherein, the outside cylinder end face of sliding sleeve with arm is provided with a collision block, and in the sliding sleeve with arm translation process, this collision block can contact with the copper sheet contact on being located at locking closure, and the copper sheet contact connects warning device.

Aforesaid intelligent anti-theft safety lock wherein, is with change sign indicating number ring, and is compressed by sliding sleeve with arm on the lead.

The utility model adopts the form input password of key turns, the content of password is exactly turning to of key and corner, this stealthy cryptographic technique is that two operations of unlatching key and rotary dial check mark in the safety cabinet coded lock are united two into one, not only significantly improve anti-" technical opening " ability of lock, also greatly facilitated user's operation.Simultaneously,, have the information transmitting capacity, thereby further strengthened the safety and the practicality of lock because this lock is connected with warning device.

The specific embodiment

As shown in Figure 1 and Figure 2, the intelligent anti-theft safety lock that the utility model provides comprises lock 4 and the lock core 2 that places in the lock 4, the mandrel bottom axle of lock core 2 is flat to be connected with a drive screw 7, the outside of lock 4 is set with the sliding sleeve with arm 3 with two transverse arms, the screw thread interlock mutually of the center screw of sliding sleeve with arm 3 and drive screw 7, the top of sliding sleeve with arm 3 is provided with lead 5, lead 5 embeds in the vertical transverse arm of sliding sleeve with arm 3, thereby sliding sleeve with arm has been played position-limiting action, sliding sleeve with arm 3 is moved horizontally under the rotary action of drive screw 7.The pull bar that is used for spurring bolt passes from locking closure, is fixed with block on the pull bar.

As shown in Figure 4,

block

8,9 is fastened on the pull bar by screw, nut, and a side of block is provided with guide wheel 10.Door lock is under the state of locking, and the horizontal cross-arm of sliding sleeve with arm is kept off below block, and bolt can't be pulled.When using key rotation lock core, lock core promptly drives drive screw and rotates, sliding sleeve with arm is moved horizontally under the rotary action of drive screw, translation along with sliding sleeve with arm, the horizontal cross-arm of sliding sleeve with arm and the gap between the lock increase gradually, can pass from the gap until block, the pull bar bolt of just can leaving behind is opened door.Except this kind mode, the utility model can also be provided with a key on the horizontal cross-arm of sliding sleeve with arm, be provided with suitable with it keyway on block, and when key and keyway aligned, pull bar can move down, and the pulling bolt is opened door.This mechanism is that the function with key on the mechanical cipher and dial unites two into one, and turn to and the corner of key are exactly the content of password, thereby have simplified operation.

As shown in Figure 6, the outside cylinder end face of sliding sleeve with arm 3 is provided with a collision block 26, in the sliding sleeve with arm 3 translation processes, this collision block 26 can contact with the copper sheet contact 22 on being located at lock, two plastic mattresses of copper sheet contact 22 usefulness and isolating shrinkable tube 27 and lock insulation, and by holding wire 24 connection warning devices.Warning device of the present utility model can be shared with doorbell is a device, also can with the sub-district janitor's room networking of ensuring public security, can also be connected the realization automatic dialup with host's telephone.The setting of alarm point should make opening be limited in minimum scope, has just passed in opening and has entered alarm condition immediately, thereby improved the theftproof performance of this lock.

According to the structure of this lock, the designer just can change operator password easily by thread rotary orientation and the pitch that changes drive screw 7.In addition, the utility model can also overlap the change sign indicating number ring 21 of different-thickness on lead 5, and is compressed by sliding sleeve with arm 3, as Fig. 1, shown in Figure 3.By adjusting the thickness that becomes sign indicating number ring 21, can change the starting point that sliding sleeve with arm 3 moves horizontally, thereby also just change the password of operation.

Fig. 5 be the B-B of Fig. 2 to view, structure has herein played the position-limiting action to pull bar.

Intelligent anti-theft safety lock of the present utility model adopts face guard-like to install, and promptly only bores the aperture of a Φ 8mm on door skin, only can hold key and just put in.Like this, unlocking person just is difficult for seeing clearly the trade mark of lock core, thereby also just is difficult for knowing the concrete structure of lock, has increased the difficulty of unblanking.
