A shoulder pole, a pin and a moving block are equipped on the locking bolt plate which is connected together to a whole with the bolt noddle, the moving block and the locking bolt plate are anastomosed plane to plane to shift longitudinally and laterally for locking and achieve the purpose of pick-proof.
Description
The utility model relates to a kind of lockset, especially a kind of lock pin pick-proof door lock.
The door lock kind of prior art is more, though the existing technically improvement in various degree of many door locks but has unsatisfactory part, is not the too high complex process of cost, is exactly function singleness, and anti-prying is poor, and defective such as application life is long.
The purpose of this utility model provides a kind of rational in infrastructure, the lock pin lock that anti-prying is strong.
The purpose of this utility model is achieved like this: it mainly is made up of lock housing, bolt head, lock bolt plate, motion block, lock core shifting block and universe rod.Be provided with a decorative panel in the lock housing side, this decorative panel is connected with lock housing.Described bolt head and lock bolt plate fuse, and are provided with shoulder pole, pin A, pin B and motion block on lock bolt plate.When locking, tiltedly bolt is under the effect of the collision of door and doorframe and oblique bolt stage clip and automatic unidirectional locking, during as multidirectional locking, key is turned clockwise, make the lock core shifting block promote motion block, the shooting the lock-bolt plate stretches out outside the decorative panel bull locking bolt do translation then, and the pin B that is located at simultaneously on the lock bolt plate promotes universe rod, reaches multidirectional purpose of locking; When unblanking, key is rotated counterclockwise, stirs shoulder pole at last and promote the shoulder pole shift fork, reach the purpose of unblanking after making the shoulder pole shift fork stir oblique bolt location-plate.
Owing to adopt such scheme, the utlity model has advantages such as rational in infrastructure, that unlatching is flexible, anti-prying is strong.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
