Description

The anti-theft cipher padlock

The utility model belongs to field of lockset, specifically a kind of suitable shipping car door or warehouse gate anti-theft cipher padlock.

What car door that conveys goods for a long time or container door often used is common padlock or lead sealing, in order that prevent loss of goods, but is to prevent that goods and materials are stolen like this.Especially vehicle ' is in meagrely-populated or operation at night in the driving way, and the people that commits theft climbs up car and is easy to open the car door theft.In addition, just must be with key at the shipping railway carriage or the container of railway transportation as if the use padlock, the operation between respectively standing in the whole nation of railway carriage or container is used, and uses also inconvenience.

The purpose of this utility model provides a kind of certain theftproof performance that has, broad-spectrum anti-theft cipher padlock.

The purpose of this utility model is achieved in that mainly forms the anti-theft cipher padlock by latch plate, locking closure box, locking bolt and lock pin control device.Latch plate and locking closure box are formed a sealing lock box, and locking bolt and the design and installation of lock pin control device are in the sealing lock box.In the middle of latch plate, have elongated hole, the door nose can insert in the elongated hole, the locking bolt that is positioned on the latch plate passes the door nostril hole, the locking bolt front end has boss to insert in the positive stop hole, locking bolt can teeter, form the lock pin control device by central axis, digital ring, screw rod, bolt, thumb wheel and pintle hook lock, screw rod and bolt are outwards retired and are driven rocking arm and make pintle hook lock block the notch of locking bolt during trackwheel, then the number of number ring is stirred, central axis and digital ring just can not move to axial, it is motionless that thumb wheel also changes, and door is locked.Stir digital ring when unblanking earlier to good number, the thumb wheel backward rotation, screw rod and bolt move to the thumb wheel center, and pintle hook lock can withdraw from the notch of locking bolt.

Advantage of the present utility model: product with compact structure is firm, is fit to the door of various use padlocks; Make things convenient for the railway transportation car door to use especially, can prevent in the vehicle operating way or when stopping the stranger open car door and steal goods; Only need on waybill, to fill in the number of this lock during use, only touch the personnel of waybill, could check the number and open lock.This lock theftproof performance is good.
