Description

Lock

Technical field

The utility model relates to mechanical lock, has related in particular to a kind of lock.

Background technology

At present, general mechanical lock mostly is simple cylinder lock, and it is simple in structure, only can play common antitheft effect.And,, thereby causing owner's property stolen as long as common mechanical lock can be destroyed by master key for experienced slightly thief, it can't play antitheft effect at all.

Summary of the invention

The utility model is poor at mechanical lock theftproof performance in the prior art, as long as generally pass through master key, destroy pellet shot from a slingshot, lock can be destroyed, feasible lock has lost shortcomings such as anti-theft feature, provide a kind of, had the person of avoiding theft carries out violent lock breaking by master key lock by what the spring mortice lock was combined with cylinder lock.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

Lock comprises lock core body, cover plate and key, and described lock core body comprises spring mortice lock and cylinder lock and spring, and spring mortice lock and cylinder lock all are arranged in the lock core body.Crack with the high advantage of the accuracy of cylinder lock by anti-violence and to mutually combine, thereby make this lockset have better theftproof performance the spring mortice lock.

As preferably, described spring mortice lock comprises spring leaf, and spring leaf is provided with the spring leaf lockhole, and spring leaf comprises the projection that cooperates with the concave surface that is provided with on the lock core body, also is provided with annular groove in the lock core body.Owing to be provided with concave surface on the lock core body, be provided with projection on the spring leaf, projection and concave surface cooperatively interact, therefore, when spring leaf is not compressed to specific annular groove place, even key inserts lock core body, key also can't rotate, and has prevented that so promptly the thief from utilizing master key to carry out violent lock breaking.After lockset is opened,, extract key because therefore the effect of spring force returns to original position with spring leaf.

As preferably, described cover plate is arranged on the lock core body, and cover plate is provided with rectangular aperture, and the center of cover plate is provided with circular hole, and cylinder lock is provided with the pellet shot from a slingshot lockhole.

As preferably, described key comprises rotating shaft, spring section and pellet shot from a slingshot section, and the spring section cooperates with the spring mortice lock, and the pellet shot from a slingshot section cooperates with cylinder lock, and the diameter of rotating shaft is less than the circular hole at the center of cover plate.In the time of in key inserts lock core body, at this moment, key can't rotate, after key pressed inward, because the length of spring section on the key equates that to the annular groove distance in the lock core body therefore spring leaf is pushed in the annular groove, the pellet shot from a slingshot section of key has also entered cylinder lock simultaneously with spring leaf, at this moment key promptly can rotate, thereby lockset is opened.

As preferably, be provided with a spring mortice lock and a cylinder lock in the described lock core body, the spring leaf lock is positioned at the top of cylinder lock.

As preferably, be provided with a spring mortice lock and a cylinder lock in the described lock core body, the spring leaf lock is positioned at the bottom of cylinder lock.

As preferably, be provided with two spring mortice locks and a cylinder lock in the described lock core body, a spring leaf lock is positioned at the top of cylinder lock, and a spring leaf lock is positioned at the bottom of cylinder lock.Two spring mortice locks are set, so anti-theft effect is better.

As preferably, described spring leaf lockhole, pellet shot from a slingshot lockhole are the yi word pattern lockhole, and key is the yi word pattern key.

As preferably, described spring leaf lockhole, pellet shot from a slingshot lockhole are cross lockhole, and key is cross key.

The utility model is owing to adopted above technical scheme, and have significant technique effect: the utility model combines the spring mortice lock with cylinder lock, and the person that can effectively not avoid theft utilizes master key to carry out violent lock breaking, has guaranteed the safety of user's property.

The specific embodiment

Below in conjunction with accompanying drawing 1 to Fig. 5 and embodiment the utility model is described in further detail:

Embodiment 1

Lock as shown in Figure 1 to Figure 3, comprises lock core body 1, cover plate 6 and key 5, and described lock core body 1 comprises spring mortice lock 2 and cylinder lock 4 and spring 3, and spring mortice lock 2 all is arranged in the lock core body 1 with cylinder lock 4.Crack with the high advantage of the accuracy of cylinder lock 4 by anti-violence and to mutually combine, thereby make this lockset have better theftproof performance spring mortice lock 2.

Spring mortice lock 2 comprises spring leaf 21, and spring leaf 21 is provided with spring leaf lockhole 23, and spring leaf 21 comprises the projection 22 that cooperates with the concave surface 11 that is provided with on the lock core body 1, also is provided with annular groove 12 in the lock core body 1.Owing to be provided with concave surface 11 on the lock core body 1, be provided with projection 22 on the spring leaf 21, projection 22 cooperatively interacts with concave surface 11, therefore, when spring leaf 21 is not compressed to specific annular groove 12 places, even key 5 inserts lock core body 1, key 5 also can't rotate, and has prevented that so promptly the thief from utilizing master key to carry out violent lock breaking.After lockset is opened,, extract key 5 because therefore the effect of spring 3 elastic force returns to original position with spring leaf 21.Cover plate 6 is arranged on the lock core body 1, and cover plate 6 is provided with rectangular aperture 61, and the center of cover plate 6 is provided with circular hole 62, and cylinder lock 4 is provided with pellet shot from a slingshot lockhole 41.

Key 5 comprises rotating shaft 51, spring section 52 and pellet shot from a slingshot section 54, and spring section 52 cooperates with spring mortice lock 2, and pellet shot from a slingshot section 54 cooperates with cylinder lock 4, and the diameter of rotating shaft 51 is less than the circular hole 62 at the center of cover plate 6.When key 5 inserts in the lock core body 1, at this moment, key 5 can't rotate, after key 5 pressed inward, because the length of the spring section 52 on the key 5 equates that to annular groove 12 distances in the lock core body 1 therefore spring leaf 21 is pushed in the annular groove 12, the pellet shot from a slingshot section 54 of key 5 has also entered cylinder lock 4 simultaneously with spring leaf 21, at this moment key 5 promptly can rotate, thereby lockset is opened.Be provided with a spring mortice lock 2 and a cylinder lock 4 in the lock core body 1, spring mortice lock 2 is positioned at the top of cylinder lock 4.
