Description

A kind of pick-proof lock and key

Technical field

The utility model relates to a kind of lockset, relates in particular to a kind of pick-proof lock and key.

Background technology

Existing lockset generally all adopts the action of lock core control spring stop mechanism to realize the folding of locking bolt, and there is the defective of easily pulling out, easily prizing in this structure.Disclosed utility model patent technical literature " a kind of safety automatic lock " application number is 91218372.1 before, notification number is CN2099160U, it has adopted lock core to be meshed with locking bolt, the rotation that limits together lock core with upper pellet and lower pellet with spring comes sealed mechanism, thereby owing to can back down upper pellet with other objects lock core is rotated, perhaps picking lock bolt firmly, when spring bent, lock core also can rotate, and did not so just reach effectively sealed purpose.

The utility model content

For above defective, the utility model provide a kind of can be effectively sealed, the pick-proof lock that difficult quilt is prized and key are to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of pick-proof lock and key, comprise lock body, locking bolt, lock core is installed in rotation in the lock body, its neighboring is provided with teeth groove, dead bolt also is installed in the lock body, rotating disk, price fixing, teeth groove engagement on latch and the lock core is arranged on the dead bolt, the Compress Spring two ends are packed in respectively on dead bolt tail end and the lock body, when being in locked state, dead bolt stretches on the locking bolt in the breach on the correspondence position with it, rotating disk is contained in the lock core skin rotationally, price fixing is packed on the lock body and is in the rotating disk skin, price fixing and rotating disk are respectively arranged with key hole in the same way on same position, there are key groove and key hole to intersect on the lock core, the key trench bottom has a diameter at least greater than the marble hole of key well width, on the lock body with on the marble hole relevant position shrinkage pool is arranged, and a pellet part is in marble hole, a part is in shrinkage pool, and both ends of the spring minute other country is connected on the not-go-end of pellet and shrinkage pool.The number of key bit and position are consistent with the through hole on the lock core.

The beneficial effect of pick-proof lock described in the utility model and key is: adopt after this structure since must make first rotating disk forward to key hole on the rotating disk and the key groove on the lock core over against, key bit on key ability corresponding with the marble hole behind key groove rotational lock core, open lock, and price fixing can cover through hole, has so just overcome the defective that common lockset easily pulls out, easily prizes.And key when rotating with lock core in pellet do not rub, prolonged the application life of lock and key.

The specific embodiment

Such as Fig. 1, shown in Figure 2, the utility model comprises lock body 1, locking bolt 3, lock core 6, lock core 6 is installed in rotation in the lock body 1, teeth groove 18 is arranged on its neighboring, dead bolt 2 also is installed in the lock body 1, rotating disk 5, price fixing 4, latch 12 is arranged on the dead bolt 2, dead bolt 2 is connected with a joggle by latch 12 and teeth groove 18 with lock core 6, Compress Spring 13 two ends are packed in respectively on dead bolt 2 tail ends and the lock body 1, when being in locked state, dead bolt 2 stretches on the locking bolt 3 in the breach 7 on the correspondence position with it, rotating disk 5 is contained in lock core 6 skins rotationally, price fixing 4 is packed on the lock body 1 and is in rotating disk 5 skins, such as Fig. 3, Fig. 4, shown in Figure 5, price fixing 4 is respectively arranged with key hole 21 in the same way with rotating disk 5 on same position, 9, such as Fig. 1, Fig. 6, shown in Figure 7, key groove 22 and key hole square crossing are arranged on the lock core 6, the key trench bottom has a diameter at least greater than the marble hole 8 of key well width, on the lock body 1 with on marble hole 8 relevant positions shrinkage pool 20 is arranged, pellet 17 parts are in marble hole 8, a part is in shrinkage pool 20, and spring 16 two ends are fixed in respectively on the not-go-end of pellet 17 and shrinkage pool 20.Such as Fig. 1, shown in Figure 6, jagged 10 on the lock core 6, dead bolt 2 was corresponding with the engagement range of lock core 6 when the corresponding alignment pin 11 that is fixed with on the lock body 1, alignment pin 11 made the slewing area of lock core 6 lock with open and close.The number of key bit and position are consistent with the through hole on the lock core, and the key bit on the key is corresponding with the marble hole behind the key groove.

Such as the key that Fig. 8, padlock shown in Figure 9 and of the present utility model cooperate, the number of its key bit 19, the position is consistent with the through hole 8 on the lock core 6.

When unblanking, key is inserted price fixing 4, rotating disk 5, clockwise rotate key, make rotating disk 5 rotations, when the key groove 22 on the key hole 9 on the rotating disk 5 and the lock core 6 over against the time, continue to insert key, key bit 19 is entered in the marble hole 8 on the lock core 6, clockwise rotate again key, band movable lock core 6 rotates, and by latch 12, the teeth groove 18 that meshes dead bolt 2 is retreated, and compressed spring 14 ejects locking bolt 3, the ejection length of bayonet lock 15 restriction locking bolts is so just opened lock.

When shutting, locking bolt 3 is pressed into lock body 1, and when the breach 7 on the locking bolt 3 during over against dead bolt 2, Compress Spring 13 pushes dead bolt 2 in the breach 7, dead bolt 2 band movable lock cores 6 reset simultaneously, and the alignment pin 11 on the lock body 1 is accurate with the position that the breach 10 on the lock core 6 resets lock core.At this moment key bit 19 is extracted in marble hole 8, rotated counterclockwise key, drive rotating disk 5 and rotate, make the key hole on the rotating disk 5 identical with key hole direction on the price fixing 4, then key is extracted and got final product.

Owing to utilizing dead bolt to block locking bolt, sound construction, and through hole and key hole not over against, like this, do not use with the phase-locked key that cooperates and just lock can't be pried open or unpluged.

Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
