Abstract

The utility model discloses a lock core and a key for a cylinder lock, which integrates the characteristics of a cross spoon and a flat spoon, wherein, the lock core comprises an inner and an outer lock cores which can correspondingly rotate. The utility model is characterized in that a key hole of the lock core forms a T shape and cylinder grooves and the lock core is distributed with cylinder grooves and holes at the T-shaped transmitting direction of the key hole; the T-shaped top surface of the key hole is distributed with the cylinder grooves and holes and outer layer cylinders, inner layer cylinders and springs are arranged in the cylinder grooves and holes; the inserted-key section corresponding to the key hole forms a T shape; each T-shaped end of the key is provided with an edge tooth corresponding to the inner layer cylinders and the T-shaped top surface is provided with locking screws corresponding to the inner layer cylinders.

Description

A kind of cylinder of spring lock and key thereof

The utility model relates to a kind of cylinder of spring lock and key thereof.

Present cylinder lock has and uses cross-key, also has to use the plane spoon, and its basic structure includes relatively turnable inside and outside lock core, and internal cylinder has the pellet shot from a slingshot hole, and the outer lock core correspondence has bullet groove, and forward and backward pellet shot from a slingshot and spring are housed in bullet groove, the hole.Just can unblank when the cylinder lock of cross-key, regulation insert key by direction, but when unblanking night, the direction of insertion of key is difficult to identification, normal wrong plug direction so that be difficult to extract, even make a mess of lock core.In addition, the mutual opening rate of cross-key lock is higher, and theftproof performance is low relatively.To use the cylinder lock of plane spoon, no matter be to use the plane spoon of heel teeth, also be to use the plane spoon that has tartar in the plane, key often can positive and negative two to inserting or extract so that make a mess of lock core.Moreover the cylinder lock mutual opening rate of plane spoon is higher.Therefore, be necessary to do further improvement.

For addressing the above problem, the purpose of this utility model is to provide a kind of cylinder of spring lock and the key thereof of a kind of comprehensive cross-key and plane spoon cylinder lock feature.

For achieving the above object, the utility model adopts following scheme:

A kind of cylinder of spring lock, include relatively turnable inside and outside lock core, it is characterized in that lock core keyhole is the T type, internal cylinder is dispersed in the T of keyhole type and is distributed with the pellet shot from a slingshot hole on the direction, the outer lock core correspondence has bullet groove, and outer pellet shot from a slingshot, internal layer pellet shot from a slingshot and spring are housed in bullet groove, the hole; Internal cylinder is distributed with the pellet shot from a slingshot hole on the T of keyhole type end face, the outer lock core correspondence has bullet groove, and outer pellet shot from a slingshot, internal layer pellet shot from a slingshot and spring are housed in bullet groove, the hole.

A kind of key that is used for above-mentioned cylinder of spring lock, it is characterized in that key insertion portion cross section corresponding with keyhole be the T type, key has the heel teeth corresponding with pellet shot from a slingshot in each end of T type, has the tartar corresponding with pellet shot from a slingshot on T type end face.

The utility model is the cylinder lock that cross-key combines with the plane spoon, and mutual opening rate is low, and theftproof performance is higher, can prevent joining spoon.Because keyhole is the T type, can better confirm direction of insertion, stops the possibility of multidirectional insertion key; Because the pellet shot from a slingshot on the T type end face and bullet groove, hole and T type are dispersed pellet shot from a slingshot on the direction and bullet groove, hole size does not conform to, stopped multidirectional possibility of extracting key again.

Further describe the utility model for illustrating better below in conjunction with accompanying drawing.

Fig. 7; The A-A sectional view of Fig. 5.

As shown in Figure 1, 2, 3, cylinder of spring lock described in the utility model, include relatively turnable internal cylinder 1, outer lock core 2, it is characterized in that lock core keyhole 3 is the T type, internal cylinder 1 is dispersed in the T of keyhole 3 type and is distributed with pellet shot from a slingshot hole 5 on the direction, the outer lock core correspondence has bullet groove 6, and outer pellet shot from a slingshot 7, internal layer pellet shot from a slingshot 8 and spring 9 are housed in bullet groove 6, the pellet shot from a slingshot hole 5; Internal cylinder 1 is distributed with pellet shot from a slingshot hole 10 on the T of keyhole 3 type end face, the outer lock core correspondence has bullet groove 11, and bullet groove 11 is equipped with outer pellet shot from a slingshot 12, internal layer pellet shot from a slingshot 13 and spring 14 in the pellet shot from a slingshot hole 10, and wherein lower floor's pellet shot from a slingshot 13 is convex.Internal layer pellet shot from a slingshot 13 also can be a magnetic bullet in addition.

As Fig. 4,5,6,7, a kind of key 4 that is used for above-mentioned cylinder of spring lock, its insertion portion cross section and keyhole 3 are corresponding is the T type, and key has the heel teeth 15 corresponding with internal layer pellet shot from a slingshot 8 in each end of T type, has the tartar 16 corresponding with internal layer pellet shot from a slingshot 13 on T type end face.If internal layer pellet shot from a slingshot 13 is magnetic bullets, key is corresponding being distributed with and internal layer pellet shot from a slingshot 13 homopolarities or the relative magnetic bead of heteropole on T type end face.

With the insertion T type keyhole that T type key is complied with, heel teeth 15 is corresponding with internal layer pellet shot from a slingshot 8, tartar 16 and the internal layer pellet shot from a slingshot 13 corresponding (Fig. 1) that is convex.The utility model can only insert and a direction be extracted key key from direction, and the phenomenon that prevents stuck key occurs, and mutual opening rate supports, and it is higher to steal performance, can prevent joining spoon.
