The spring lock is characterized in that the lock cylinder (2) is provided with a cross groove, one groove is a spring groove, the other groove is internally provided with the lock cylinder rotor (3) with a cross groove, one groove is a key groove, another groove is internally provided with a latch (6) and fixed with an inner key (4), and a cylinder and a hole of the key (10) correspond to bulges on the latch one by one. The spring lock has simple structure, is provided with the latch and the inner key simultaneously, can close the key groove, and effectively prevent lawbreakers from unlocking the lock by stirring the spring, thus being safe.

Description

Cylinder lock

Technical field

The utility model relates to a kind of cylinder lock.

Background technology

Existing cylinder lock, it generally includes a lock body, is installed in the interior lock core of lock body and wherein lock core rotor, pellet shot from a slingshot and marble spring.Existing this cylinder lock lawless person ratio is easier to push aside, when it utilizes instrument to stir pellet shot from a slingshot, again lock core is applied commutation torsion, stir pellet shot from a slingshot up and down with instrument in this case, the interface that makes the interface arrival of two pellets shot from a slingshot wherein and lock body and lock core is in conplane state following time, can send kaka sound, at this moment, the lawless person will position this pellet shot from a slingshot, then repeats same step, each following pellet shot from a slingshot is all accurately located, defeat in detail, and then a lock opens, that is to say that existing cylinder lock exists to stir pellet shot from a slingshot up and down, and the defective that the pellet shot from a slingshot location is opened, so poor stability.

The cylinder lock that has tamper-resistant function in the market is also a lot, as the patent No. is that the Chinese utility model patent " a kind of pick-proof lock core " of ZL200320125595.0 (notification number is CN2665306Y) has disclosed the structure so a kind of, it comprises lock core body and wherein lock core rotor, pellet shot from a slingshot and marble spring, it is characterized in that also comprising: be located between lock core body and the lock core rotor rotor cover of rotatable 360 degree; The inner end head of described rotor cover, be provided with pulling block: in lock core body, rotor cover and rotor, be respectively equipped with in each corresponding pellet shot from a slingshot hole spring, on pellet shot from a slingshot, middle pellet shot from a slingshot and following pellet shot from a slingshot, pellet shot from a slingshot hole in the rotor cover is the little stairstepping circular hole of outer imperial palace, pellet shot from a slingshot wherein is corresponding also to be the little ladder cylinder of outer imperial palace, and pellet shot from a slingshot length is according to cooperating of key bit its length being set in each.This lock core just can make rotor and rotor cover rotate together when having only valid key to insert, rotor and rotor cover did not all rotate or has only rotor rotation and the rotor cover does not rotate when the key that do not match inserted, and lock still can not be opened.Though it can play tamper-resistant function, this structure can not prevent effectively that still the lawless person from stirring the pellet shot from a slingshot method and opening cylinder lock.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and can effectively prevent the cylinder lock that the lawless person opens with stirring the method for pellet shot from a slingshot.

The utility model adopts following technical scheme: a kind of cylinder lock, comprise outer lock body, be installed in the lock core in the outer lock body, lock core rotor, key, it is characterized in that: described lock core has a cross recess, article one, groove is the bullet groove that is arranged at intervals with the pellet shot from a slingshot hole, be equipped with in another groove and be with a cross recessed lock core rotor, a groove of described lock core rotor is a key, be provided with a locking bolt that can rotate around the axis and another side in another groove on one side and fix key in, lower end two sides of key have key bit in described, it is an elongated driving lever, two projectioies are arranged at the top of described locking bolt, one projection is arranged at the bottom, the handle of key has a hole to being cylinder between the key bit in the centre of key bit, and is corresponding one by one with the last projection on the locking bolt.

The utility model is simple in structure, owing to have locking bolt and interior key, can close key simultaneously, can prevent effectively that the lawless person from opening with stirring the method for pellet shot from a slingshot, thus safety.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is locking bolt of the present utility model plug face figure when opening;

Fig. 3 is locking bolt of the present utility model plug face figure when closing;

Among the figure, the 1st, outer lock body, the 2nd, lock core, the 3rd, lock core rotor, the 4th, interior key, the 5th, pellet shot from a slingshot hole, the 6th, locking bolt, the 7th, axle, the 8th, dead bolt, the 9th, spring, the 10th, key.

The specific embodiment

The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:

As can be seen from Figure 1, the utility model cylinder lock, comprise outer lock body 1, be installed in lock core 2 and lock core rotor 3 in the outer lock body 1, pellet shot from a slingshot, interior key 4, spring, locking bolt 6, lock core has a cross recess, article one, groove is the bullet groove that is arranged at intervals with pellet shot from a slingshot hole 5, every pellet shot from a slingshot has pellet shot from a slingshot and marble spring in the hole, be equipped with in another groove and be with a cross recessed lock core rotor 3, a groove of lock core rotor 3 is a key, can fix key 4 in around locking bolt 6 and another side that axle 7 rotates Yi Bian be provided with one in another groove, and lower end two sides of interior key 4 have key bit, it is an elongated driving lever, two projectioies are arranged at the top of locking bolt 6, and a projection is arranged at the bottom, and the handle of key 10 is to being cylinder between the key bit, have a hole in the centre of key bit, corresponding one by one with the last projection on the locking bolt.

Using method: when unblanking, insert key, the upper end of key in the top of key props up, the projection of the shooting the lock-bolt lower end, lower end by interior key, rotate around axle 7 the locking bolt upper end, two projectioies of upper end fasten the hole and the cylinder of key 10 respectively, at this moment continue inwardly to insert key, key enters inside in propping up, the pellet shot from a slingshot of interior key bit alignment the inside on the key, the pellet shot from a slingshot of key alignment outside, thus lock can be opened.

Operating principle: when the lawless person unblanks with master key, when master key inserts, the projection of the shooting the lock-bolt lower end, lower end of interior key, rotate around axle 7 the locking bolt upper end, thereby the projection of locking bolt upper end fastens master key, close key simultaneously, master key can not inwardly insert like this, thereby has prevented that the lawless person from stirring the pellet shot from a slingshot method and opening cylinder lock.
