Abstract

The utility model discloses a locking mechanism of a padlock, comprising a lock core in a lock body and a lock beam on the lock body; the lock core is provided with a gap which can be matched with the appearance of the lock beam; the lock beam is provided with an arc-shaped spigot which is matched with the lock core appearance; the lock core is arranged at a position matched with the lock beam spigot; furthermore, the gap is corresponding to the lock beam. The locking mechanism has the advantages that a lock tongue is omitted, the lock beam with the spigot and the lock core with the gap are matched with each other; furthermore, the lock core is arranged at a position vertical to the horizontal force of the lock beam spigot; the match between the lock core and the lock body is tight without clearance; when the lock beam is subject to the external force, the displacement between the lock core and the lock beam can be avoided, the matching between the lock core and the lock beam is reinforced, and the violence-opening prevention performance of the lock is greatly improved.

Description

A kind of locking mechanism of padlock

Technical field

The utility model belongs to lockset, is specifically related to a kind of locking mechanism of padlock.

Background technology

The locking mechanism of existing padlock constitutes by cooperating with the dead bolt 2 of lock core 1 interlock and the seam 4 on the lock bridge 3 as shown in Figure 1.Also there is deficiency in this anti-violence aspect of unblanking that is locked in.When with external force F effect lock bridge 3, seam 4 on the lock bridge 3 acts on the end of dead bolt 2, can produce vertical f1 and horizontal applied force f2, and the direction of motion of dead bolt 2 and horizontal applied force f2 are equidirectional, owing to there is mechanical fit clearance (lock core 1 rotates drive dead bolt 2 and seesaws) between dead bolt 2 and the lock core 1, to force dead bolt 2 when being subjected to horizontal applied force f2 to lock core 1 direction displacement, under external force F constantly acts on repeatedly, seam 4 is easy to an inclined-plane a is impacted in the end of dead bolt 2, thereby lock is opened.

The utility model content

The purpose of this utility model is to provide a kind of locking mechanism of padlock, the anti-violence of adopting this retaining mechanism can the improve padlock performance of unblanking.

Realize that the purpose of this utility model technical scheme is: the locking mechanism of padlock, comprise lock core in the lock body and the lock bridge on the lock body, lock core is provided with the breach that can match with the lock bridge profile, lock bridge is provided with the circular arc seam that can match with the lock core profile, lock core is located at the position that can match with the lock bridge seam, and the breach on it is corresponding with lock bridge.

Described lock bridge profile is a circular pin, and the breach on the lock core is a circular arc.

Described lock bridge profile is a square pole, and the breach on the lock core is square.

Another kind of structure of the present utility model, be on lock core, to establish two breach that can match with the lock bridge profile, on the two ends of lock bridge, be provided with the circular arc seam that can match with the lock core profile, lock core is located at the position that can match with circular arc seam on the lock bridge, and the breach on the lock core is corresponding with lock bridge.

Characteristics of the present utility model are to have omitted dead bolt, directly adopt lock bridge that is provided with seam and the lock core that is provided with breach to cooperatively interact, and lock core is located at and the perpendicular position of lock bridge seam horizontal applied force, and match ratio is more very close to each other between lock core and the lock body, when being subjected to external force, lock bridge can avoid producing displacement between lock core and the lock bridge, strengthened its with lock bridge between cooperate, the anti-violence of the lockset performance of unblanking is improved greatly.The locking mechanism that lock core and lock bridge two ends cooperate simultaneously, its anti-unblanking property of violence is higher than the locking mechanism that only cooperates with lock bridge one end.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 3 is the A-A view of Fig. 2.

Fig. 4 is the different conditions schematic diagram of Fig. 3

Fig. 5 is the different structure schematic diagram that lock bridge and lock core match in the utility model.

Fig. 6 is an another kind of structural representation of the present utility model.

The specific embodiment

See Fig. 2, Fig. 3, the locking mechanism of the utility model padlock, comprise lock core 1 in the lock body 6 and the lock bridge 3 on the lock body 6, lock core 1 is provided with the circular arc cutaway 5 that can match with lock bridge 3 profiles, one end of lock bridge 3 is provided with the circular arc seam 4 that can match with lock core 1 profile, lock core 1 laterally is located at the position that can match with lock bridge seam 4 in the lock body 6, and the breach on it 5 is corresponding with lock bridge 3.

See Fig. 5, lock bridge 3 profiles also can be square pole, and breach on the lock core 15 is corresponding also to be square.

Another kind of structure of the present utility model as shown in Figure 6, it is that lock core is extended, establish two circular arc cutaway that can match with the lock bridge profile on lock core, be provided with the circular arc seam that can match with the lock core profile on the two ends of lock bridge, the breach on the lock core is corresponding with lock bridge.

Operating principle of the present utility model

When locking, elder generation's rotational lock core 1 makes breach 5 on the lock core 1 align the position of lock bridge 3 when locking, promptly coincide with the lock beam hole that is located in the lock body 6, the breach 5 of lock bridge 3 on lock core 1 inserted in the lock beam hole (referring to Fig. 4), counterclockwise rotation movable lock core 1 makes the part that does not have breach on it be positioned at the circular arc seam 4 of lock bridge 3 then, at this moment the breach 5 on the lock core 1 is in lock bridge 3 and breaks away from the position of matching, and the circular arc seam 4 that lock core 1 is positioned at lock bridge plays the position-limiting action (referring to Fig. 2, Fig. 3) to lock bridge 3.When unblanking, lock core is clockwise rotated the position of locking get final product.

Claims
