CN202055636U - Multi-pillar spring lock core - Google Patents

Abstract

The utility model relates to a multi-pillar spring lock core, which is designed to solve the technical problem that a lock is unlocked inconveniently because an inner lock core and an outer lock core of the existing similar product are loosened easily. The lock core comprises an inner lock core and an outer lock core, wherein the inner lock core is provided with internal spring holes and lock holes, the outer lock core is provided with an external spring hole, bottom holes of the internal spring holes are flushed, and a spring is arranged in the external spring hole. The utility model is characterized in that cylindrical sections with large diameters and small diameters are alternately distributed in a distance section of the internal lock core from the first internal spring hole to the last internal spring hole along the axial direction, and the internal spring holes are arranged in the cylindrical sections; and the cylindrical sections of the internal lock core are distributed in concave and convex structures. The multi-pillar spring lock core has a reasonable structure, and the height change range of the internal spring holes of the lock core is larger, so technical unlocking can be effectively prevented. The internal lock core and the external lock core are manufactured into the lock core through die casting, so the internal lock core and the external lock core are not easy to disassemble, the height structures of spring holes in the lock core can not be known, the confidentiality and the security of a lockset are improved, and the multi-pillar spring lock core is suitable for being used as structure improvement on the existing similar products.

Description

The multicolumn lock cylinder

Technical field

The utility model relates to a kind of lockset, is a kind of multicolumn lock cylinder of cylinder lock.

Background technology

Cylinder lock is modal on the market a kind of lockset, and its operating principle mainly is by the pellet shot from a slingshot of different length is set in the pellet shot from a slingshot hole of lock core, when key inserts lock core, the tooth portion of key with pellet shot from a slingshot jack-up to the sustained height plane, thereby realize unblanking.Existing billiards lock structure pattern is more, but principle is similar.Notice of authorization CN201071630Y as the Chinese patent literature publication, June 11 2008 notice of authorization day, the utility model name is called " lock cylinder of anti-skilled unlocking ", the architectural feature of this patent is that the diameter of circular lock core makes big, the little some diameter segment of tail of head, and the length of each diameter segment can be depending on a pellet shot from a slingshot hole or a plurality of pellets shot from a slingshot hole are set.By this kind structure, increased the multiple permutation and combination of lock core, thereby can improve the safety of lock.But the pellet shot from a slingshot hole height change of this kind lock core is less, and internal cylinder and outer lock core are quick detachable, know the lock core internal construction easily, cause confidentiality relatively poor.

Summary of the invention

For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of multicolumn lock cylinder that can prevent effectively that lock core is loosening to this area, and the pellet shot from a slingshot hole height change that makes it solve existing like product lock core is less, easily knows the technical problem of lock core internal construction.Its objective is and be achieved through the following technical solutions.

A kind of multicolumn lock cylinder, this lock core comprises internal cylinder, outer lock core, pellet shot from a slingshot hole and keyhole in internal cylinder is provided with, outer lock core is provided with outer pellet shot from a slingshot hole, and the bottom outlet in pellet shot from a slingshot hole flushes in each, and outer pellet shot from a slingshot is provided with spring in the hole.Its structural feature is to be provided with diameter one big, a little alternatively distributed cylindrical section, pellet shot from a slingshot hole in being provided with in the cylindrical section in described internal cylinder is vertically from pellet shot from a slingshot hole in first to the distance segment in last interior pellet shot from a slingshot hole; The cylindrical section of described internal cylinder distributes and is concaveconvex structure.By diameter one big, a little alternatively distributed cylindrical section is set on place, the interior pellet shot from a slingshot hole shaft part with internal cylinder, and the diameter of cylindrical section can be provided with arbitrarily according to the design needs, can reach the height change in hundreds of pellet shot from a slingshot holes to several thousand kinds of lock cores like this, thereby significantly improve the difficulty that master key and skill are unblanked.In addition, because of internal cylinder is provided with the different cylindrical section of diameter, and cylindrical section distributes and is concaveconvex structure, make internal cylinder and outer lock core to form lock core by die casting, internal cylinder can't be dismantled from outer lock core by normal means, thereby can't know the pellet shot from a slingshot hole attach structure of lock core inside, the confidentiality and the safety that have improved lockset.

The utility model is rational in infrastructure, and the interior pellet shot from a slingshot hole height excursion of lock core is bigger, can effectively prevent technical opening.And internal cylinder and outer lock core are made lock core by die casting, make internal cylinder and outer lock core not quick detachable, except that the lockset designer, the inner pellet shot from a slingshot of Nobody Knows lock core hole attach structure, improve the confidentiality and the safety of lockset, be suitable as the architecture advances of existing like product.

Description of drawings

Fig. 1 is an internal cylinder perspective view of the present utility model.

Fig. 2 is an internal cylinder sectional structure schematic diagram of the present utility model.

Fig. 3 is the sectional structure schematic diagram that the utility model internal cylinder cooperates with outer lock core.

Fig. 4 is the sectional structure schematic diagram that the utility model inserts key.

The specific embodiment

Now in conjunction with the accompanying drawings, the utility model is further described.The name of sequence number is called among the figure: internal cylinder 1, cylindrical section 101, interior pellet shot from a slingshot hole 102, keyhole 103, outer lock core 2, outer pellet shot from a slingshot hole 201, spring 3, outer pellet shot from a slingshot 4, interior pellet shot from a slingshot 5, key 6.

As shown in Figure 1 and Figure 2, the internal cylinder 1 of this multicolumn lock cylinder is to be provided with diameter one big, a little alternatively distributed cylindrical section 101 vertically in the distance segment in extremely last interior pellet shot from a slingshot hole, the first interior pellet shot from a slingshot hole, cylindrical section is provided with interior pellet shot from a slingshot hole 102, and promptly interior pellet shot from a slingshot hole is a height, low a distribution with cylindrical section.As shown in Figure 3, outer lock core 2 is lenticular cooperating with internal cylinder shape, and makes lock core by die casting, the outer pellet shot from a slingshot hole 201 of outer lock core and the interior pellet shot from a slingshot hole vertical alignment of internal cylinder.As shown in Figure 4, be provided with spring 3 and outer pellet shot from a slingshot 4 in the outer pellet shot from a slingshot hole of outer lock core, the interior pellet shot from a slingshot hole of internal cylinder is provided with interior pellet shot from a slingshot 5.When key 6 inserts the keyhole 103 of internal cylinder, pellet shot from a slingshot, the motion of outer pellet shot from a slingshot in the tooth portion of key promotes, length of spring compressed, pellet shot from a slingshot and the contacted surface of outer pellet shot from a slingshot place the gap between internal cylinder and the outer lock core just in this moment, key, promptly rotatable internal cylinder is finished and is unblanked.

The utility model has improved the confidentiality and the safety of lock core by above-mentioned lenticular cooperation, effectively prevents technology unlocking, has also solved the loosening problem of internal cylinder and outer lock core simultaneously.
