Abstract

The utility model relates to a rolling gate lock, in particular to an anti-theft lock of a single hook rolling gate, which aims to eliminate the defects of the present rolling gate lock, such as long lock body, complicate structure, high cost, easy torsion fracture of a lock core piston, and poor performance of anti-theft. An eccentric wheel is provided at the side where a lock core is combined with a gear, and a security hook top is combined with the eccentric wheel; when the eccentric wheel revolves, the utility model can make the security hook swing and depart from earth hook; the inner lock case is provided with step-shape anti-lock jaw and a pair of safety pieces and a handle in both sides of the step-shape anti-lock jaw, when the inner side security piece is close to the security hook, the security hook can be stopped, otherwise can swing. A guiding plate is provided between the exterior lock case inner side and the security hook which are positioned by an axle pin on which the security hook swing. The utility model has the advantages of reasonable structure, better performance of anti-theft and lower manufacturing cost.

Description

Single hook burglary-proofing lock for rolling door

One, technical field

The utility model relates to a kind of rolling gate door lock, especially a kind of single hook burglary-proofing lock for rolling door.

Two, background technology

At present, the rolling gate door lock kind on the market is more, but all is the double hook rolling gate door lock, and during latching gate, two latch hooks under its door lock can hook two ground rings on the corresponding ground, and two dead bolts of door lock both sides can insert doorframe, thereby with on the rolling gate door lock.But there is following deficiency in this double hook rolling gate door lock: the one, and lock body is about 1.2 meters, complex structure cost height; The 2nd, the robber just can make lock core bullet post twist off as long as insert the lock core twisting with reinforced Phillips screwdriver or hard iron sheet, opens and the dead bolt withdrawal thereby drive latch hook, and theftproof performance is poor.

Three, summary of the invention

The purpose of this utility model provides a kind of improved rolling gate door lock, and it can simplified structure, shorten lock body, again can be antitheft effectively.

For achieving the above object, the utility model is achieved in that

The lock core of stretching in the outside lock shell, tapered end in comprising be with gear and with a secondary scalable tooth bar of gears engaged, the one side of being inserted in gear at lock core is provided with an eccentric wheel, eccentric wheel is inserted on one auxiliary catch top, and eccentric wheel can make the auxiliary catch swing break away from the ground ring when rotating; Inboard lock housing has the step-like bayonet socket that ends, and is provided with a pair of safety plate and handle on its two sides, and the safety plate of inner face can make auxiliary catch stop when pressing close to auxiliary catch one side, otherwise auxiliary catch then can be swung.

Be provided with a guide strip between outside lock housing inner face and the auxiliary catch, a pivot pin is located the two, and auxiliary catch is as a spot wobble.

Auxiliary catch top has a slotted hole, and the middle part has an axis hole, and eccentric wheel departs from the center of circle and has a lock core hole.

The utility model is because only need to be provided with in the one side of gear the eccentric wheel and the auxiliary catch of a ring set, so structure is simpler; Owing to be provided with a stop safety plate, even twisting lock core, brute force can not unblank, simultaneously so theftproof performance is good in auxiliary catch one side; Owing to only use a hook, another hook and connecting piece thereof have been saved, in addition so cost of manufacture is lower.
