Abstract

The utility model relates to a theft-proof lock, comprising a lock body with a special shape; the lock body is provided with two lock cores which are restricted mutually and a latch hole which can be matched tightly with a latch. In the lock, the U-shaped lock beam of the existing padlock is changed to a lock pin structure. After locking, the lock pin is inserted in the pin hole of the latch and supports the blind hole of the lock pin on the lock body. Thus, the gap between the latch hole of the lock body and the latch is too small, which prevents from prying the lock through a pry bar. Because of the adoption of the lock core structure in which the lock cores are restricted mutually, two keys are needed to match with each other for opening the lock. The utility model is suitable for simultaneous supervision of two storehouses and avoids effectively the phenomenon that the staff of the storehouse steals the goods in the storehouse.

Description

Special shaped anti-theft padlock

The utility model relates to a kind of theftproof lock.

Existing lock type and kind are varied, and the particularly common door lock with various functions is found everywhere, but storehouse, warehouse be commonly big padlock with lock.The fundamental type of padlock is the U-shape lock beam, and the back is bigger with the gap of bolt because U-shape lock is locked, and the robber only need use crowbar just can easier the U-shape lock beam be pried open when destroying lock." a kind of theftproof lock " utility application (notification number 2048886) of Patent Office of the People's Republic of China's bulletin on December 6th, 89, it is characterized in that being provided with the anti-mechanism of dialling in lock bridge, lock body and dead bolt three's cooperation place, can prevent from lock to be pushed aside with sheet metal, but because the lock bridge of this lock still is the U-shaped structure, therefore, still keep away the danger that unavoidable lock is easily destroyed by ripping bar.

The purpose of this utility model provides the big padlock in a kind of alternative existing warehouse, and has the anti-theftproof lock of function of prizing and stealing.

The technical solution of the utility model is such.This theftproof lock comprises the lock body with irregular type body, and the core of two mutual restriction is arranged on the lock body, and be provided with can with the close-fitting latch hole of bolt.Change the U-shape lock girder construction into can stick in bolt lock construction, the lock pin blind hole that matches with lock pin is arranged on the lock body, two different cores of structure are furnished with the different key of profile of tooth separately.In the time will pinning, the key insertion with main core is rotated counterclockwise 360 ° and can plays safety effect.Need two keys to cooperate when unblanking.

The utlity model has following advantage:

1, because the utility model is replaced the lock bridge of existing padlock by lock pin, latch hole on the lock body can closely cooperate with bolt in addition, after locking, lock pin inserts the bolt pin-and-hole and withstands lock pin blind hole on the lock body, make that the gap is minimum between lock body latch hole and the bolt, do not have the crowbar fulcrum, prevented possibility with the crowbar picking lock;

2, adopted the two-core structure of mutual restriction, when unblanking, it is also not all right only to open main core, lock could be opened after secondary core must being opened.Therefore, the storehouse that needs two people to supervise simultaneously can prevent the phenomenon of defalcating effectively.

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.

Fig. 1 is a surface structure schematic diagram of the present utility model.

Fig. 2 is design of part figure of the present utility model.

Fig. 3 is the utility model user mode figure.

As shown in the figure, the utility model comprises lock body (1), main core (3), secondary core (4) and lock pin (6), lock body (1) be provided with can with the close-fitting latch hole of bolt (5), and the lock pin blind hole (18) that matches with lock pin (6) is arranged.(9) for settling the lockpin hole of lock (6) and return spring (10).Main core (3) and secondary core (4) are installed in respectively in two lock core holes (14), and dowel hole (7) is used to settle alignment pin, spring and rivet.Pin hole (16) is used to settle core latch, spring and rivet (17), (8) alignment pin for matching with lock pin key seat (2).The structure and the mounting means of parts such as core, pellet shot from a slingshot, alignment pin are identical with the cylinder lock of prior art among the figure.When locking, hand push key seat (2) makes lock pin (6) withstand blind hole (18) can finish the first road locking function; Insert lock core hole with the main lock core key, change 360 ° counterclockwise, finish the second road locking function.When unblanking, earlier insert lock core hole with secondary core key, Rotate 180 °, and then, transfer 360 ° clockwise to main core key insertion lock core hole, lock can be opened.
