Description

A kind of padlock

Technical field

The utility model relates to the lockset industry, relates in particular to a kind of padlock.

Background technology

Padlock is a kind of lockset commonly used, and the key that key inserts in the lock body is rotated the switch of realizing padlock.Existing padlock body structure mainly comprises lock core sleeve, lock core, pellet shot from a slingshot and marble spring, lock core is contained in the lock core sleeve, pellet shot from a slingshot is installed in the lock core, pellet shot from a slingshot is against on the lock core sleeve inside wall by the marble spring of rear end, and key driving lock core inserted by key and the lock core sleeve rotation realizes unblanking.The defective of existing lockset is that lock body is prized easily, pries open lock core sleeve spring place pellet shot from a slingshot and has just lost efficacy, and whole lock just scrapped, and security performance is lower; The marble spring rear end is long-term in addition and lock core sleeve inside wall frictional rotation, and marble spring damages easily, also can influence the use of padlock.

Summary of the invention

In order to solve the defective that existing padlock exists, goal of the invention of the present utility model provides a kind of novel structure, and security performance is good, the non-damageable padlock of marble spring.

To achieve the above object, the utility model has adopted following technical scheme:

A kind of padlock is made of lock body and lock bridge, and lock body comprises lock core sleeve, lock core, pellet shot from a slingshot and marble spring, and lock core is contained in the lock core sleeve, and pellet shot from a slingshot is installed in the lock core, also is provided with key in the lock core, and lock body also comprises cover, locking plate and locking plate spring in the lock core; Described pellet shot from a slingshot is provided with the cannelure corresponding with locking plate, and pellet shot from a slingshot is vertical with locking plate to be provided with, and locking plate one end is against on the pellet shot from a slingshot, and the locking plate spring housing is contained on the locking plate; Be sleeved in the lock core between lock core sleeve and the lock core, overlap in the marble spring of pellet shot from a slingshot by its rear end and the lock core and link to each other, the pellet shot from a slingshot front position is corresponding with the key position.

As preferably, described pellet shot from a slingshot is horizontal a plurality of.

As preferably, described lock core sleeve inside wall is provided with the locking plate groove, and the locking plate other end passes and is placed in the lock core in the locking plate groove.

As preferably, described cannelure width is corresponding with locking plate.

As preferably, described pellet shot from a slingshot tail end is provided with groove, and marble spring one end places in the groove, overlaps in the other end and the lock core to link to each other.

As preferably, pellet shot from a slingshot is installed in the bullet groove in the lock core, and bullet groove is mutual vertical with key and be communicated with.

The utility model is owing to adopted a kind of padlock of technique scheme, pellet shot from a slingshot is provided with cannelure, pellet shot from a slingshot is vertical with locking plate to be provided with, moving up and down of key control pellet shot from a slingshot realizes whether locking plate is stuck in the cannelure of pellet shot from a slingshot, and the cannelure of pellet shot from a slingshot is interior could be realized unblanking by the key rotational lock core thereby locking plate is stuck in.The interior cover of lock core that is contained between lock core sleeve and the lock core can effectively be protected marble spring; lock core and lock core sleeve are equivalent to cover rotation in lock core sleeve and the lock core when rotating; cover inside wall fixed-site in marble spring rear end and the lock core; the marble spring rear end not with the lock core sleeve friction, greatly reduce the probability that marble spring damages.Pellet shot from a slingshot in this padlock body is difficult for being lost efficacy because of prizing, and has novel structure, the advantage that marble spring is not fragile, security performance is good.

The specific embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 the specific embodiment of the present utility model is made a detailed explanation.

As Fig. 1, Fig. 2, a kind of padlock shown in Figure 3, constitute by lock body and lock bridge, wherein lock body by overlap 1 in lock core sleeve 2, lock core 3, pellet shot from a slingshot 5, marble spring 8, the lock core, locking plate 6 and locking plate spring 7 constitute.

Lock core 3 is contained in the lock core sleeve 2, is provided with bullet groove 12 and key 4 in the lock core 3.Pellet shot from a slingshot 5 is installed in the bullet groove 12 in the lock core 3, and bullet groove 12 and key 4 are mutual vertical and be communicated with, and pellet shot from a slingshot 5 is horizontal a plurality of.Lock core sleeve 2 inside walls are provided with locking plate groove 11.Pellet shot from a slingshot 5 is provided with the cannelure 51 corresponding with locking plate 6, and cannelure 51 width are corresponding with locking plate 6.Pellet shot from a slingshot 5 and locking plate 6 vertical settings, and locking plate 6 one ends are against on the pellet shot from a slingshot 5, the other end pass that cover 1 places in the locking plate groove 11 in the lock core.Locking plate spring 7 is sleeved on the locking plate 6.Cover 1 is contained between lock core sleeve 2 and the lock core 3 in the lock core, pellet shot from a slingshot 5 front positions are corresponding with key 4 positions, pellet shot from a slingshot 5 links to each other with cover 1 in the lock core by the marble spring 8 of its rear end, concrete pellet shot from a slingshot 5 rear ends are provided with groove 52, marble spring 8 one ends place in the groove 52, and the other end links to each other with cover 1 in the lock core.

During the lock body locked state, locking plate 6 front ends are against on pellet shot from a slingshot 5 lateral walls, and its position is the top that is in cannelure 51, and locking plate 6 front ends place in the locking plate groove 11, and rearward end is against on lock core sleeve 2 inside walls.Pellet shot from a slingshot 5 front ends stretch in the key 4.

When unblanking, key 9 inserts key 4 pellet shot from a slingshot in it 5 is upwards pushed up, marble spring 8 compressions of pellet shot from a slingshot 5 rear ends, move on the pellet shot from a slingshot 5 until locking plate 6 front ends and snap in the cannelure 51, be equivalent to lock core sleeve 2, lock core 3 and key 9 this moment and realize interlock by locking plate 6 and pellet shot from a slingshot 5, be that locking plate 6 and pellet shot from a slingshot 5 drives lock cores 3 and do with lock core sleeve 2 and relatively rotate, lock is opened.Extract key 9, compressed marble spring 8 automatically resets, and pellet shot from a slingshot 5 moves down, and locking plate 6 front ends are against on pellet shot from a slingshot 5 lateral walls of top of cannelure 51 and promptly get back to the lock body locked state.

The interior cover 1 of lock core that is contained between lock core sleeve 2 and the lock core 3 can effectively be protected marble spring 8; lock core 3 is equivalent to lock core sleeve 2 and rotates with the interior cover 1 of lock core when rotating with lock core sleeve 2; cover 1 inside wall fixed-site in marble spring 8 rear ends and the lock core; marble spring 8 rear ends rubbing with lock core sleeve 2, do not greatly reduce the probability that marble spring 8 damages.
