Description

Racking lock

The utility model relates to a kind of spline-simulating cylinder lock.

At present, the common spring lock is because the key broad is again straight shape; And the long and short rate of change of pellet shot from a slingshot is low, the permutations number is little, size of key is low; The thief is that available master key is very easily with its unlatching.For this reason, people have worked out various antitheft, alarming locks for for the purpose of the security insurance; Therefore, occur omnifarious lock such as cross on the market and arranged cylinder lock, Electromagnetic anti-theft lock, electronic puzzle theft-proof lock etc. more; The shortcoming great majority of these locks still with common lock with, promptly the permutations of pellet shot from a slingshot is low excessively in the lock, size of key is few or key excesssive gap etc.; Magnetic lock then since magnetic material very easily is magnetized or under higher temperature loss of excitation, and can't guarantee the good operation of opening/locking of lockset; Electronic password lock then needs power supply, and very easily with the power line short circuit and lockset is opened; In addition, various mechanical type cylinder locks are when boring lock core with electric drill, and then lock core is destroyed, and the long and short pellet shot from a slingshot in the lock core all drops out, and lock body separates with lock core, lockset can be opened; Therefore, because there is various defective in above-mentioned various locksets, there is not a kind of lockset generally to promote widely so far yet.

The purpose of this utility model is for the spline-simulating cylinder lock that a kind of pellet shot from a slingshot permutations is big, size of key is high, anti-drilling, antitheft, safe and reliable is provided.

The purpose of this utility model can realize by following measure:

A kind of spline-simulating cylinder lock contains long marble, short pellet shot from a slingshot, lock body, lock core, core bar etc.; The inwall of its lock core becomes triangular prism shaped; Axial direction at the lock core inwall is provided with the annular pellet shot from a slingshot hole slot that the spline-simulating more than at least two rows is arranged; The pellet shot from a slingshot hole slot is the circumscribed circle of the triangular prism shaped section triangle of lock core inwall; The pellet shot from a slingshot hole slot place that locates perpendicular to each limit of lock core inwall triangular prism on lock core respectively establishes row's pellet shot from a slingshot hole respectively; Aperture, pellet shot from a slingshot hole in the lock core is greater than the groove width of pellet shot from a slingshot hole slot; At lock core sleeve lock body is arranged; Outside lock body, be with the lock body shell; Opposite position place, pellet shot from a slingshot hole with lock core on lock body and lock body shell is equipped with the pellet shot from a slingshot hole; The long marble of dress all becomes T shape in the pellet shot from a slingshot hole of lock body and the pellet shot from a slingshot hole of lock body; The outer wall of locating in the pellet shot from a slingshot hole of lock body is fixed with a circle wire spring.

A kind of key that is used for the spline-simulating cylinder lock is the key gear piece that is circumscribed with the one-tenth spline-simulating arrangement that at least two rows pellet shot from a slingshot hole slot number above and in the lock core equates on the axial direction of key bar, the key gear piece becomes the triangle similar to the lock core inwall, the intersection, every both sides of key gear piece is key bit, and the thickness of key gear piece is equal to or less than the groove width of pellet shot from a slingshot hole slot in the lock core; The space width of key gear piece equals the separation of pellet shot from a slingshot hole slot in the lock core.

The inner wall section of lock core and key gear piece profile also can be other polygons beyond the triangle.

The utility model has following advantage compared to existing technology:

1, the utility model is established number row pellet shot from a slingshot hole pellet shot from a slingshot one week of hole and groove ring with each row and is formed a unit, in axial direction is provided with the pellet shot from a slingshot hole slot more than at least two rows altogether in lock core, i.e. at least two above unit; Therefore, the permutations number of pellet shot from a slingshot of the present utility model is big, size of key is high; With each unit three row's pellet shot from a slingshot, totally seven unit calculate, and the size of key of this lock is up to 10,400,000,000; Be higher than common spring lock and many row's cylinder locks far away.

2, the aperture in the pellet shot from a slingshot hole in the lock core of the present utility model is greater than the groove width of pellet shot from a slingshot hole slot, when in the pellet shot from a slingshot hole of lock core short pellet shot from a slingshot being housed, the diameter of short pellet shot from a slingshot is greater than the groove width of pellet shot from a slingshot hole slot, thereby short pellet shot from a slingshot can not enter in the lock core in the cinclides fully, avoided the thief to replace the thin slice of keys directly to contact pellet shot from a slingshot with other and lockset is opened.

3, the long marble of adorning in pellet shot from a slingshot hole in the lock body of the present utility model and the pellet shot from a slingshot hole is T shape; When the lock core inwall being destroyed when boring lock core with electric drill, short pellet shot from a slingshot in the lock core drops out, and the both wings of the long marble in the lock body touch mutually with the boss in pellet shot from a slingshot hole, and the unlikely lock core that all enters is interior and drop out, long marble still can connect firmly lock body and lock core, still lockset can not be opened; Therefore, this lock is anti-drilling, antitheft, and this is locked in lock core inwall center core bar is housed in addition, also can be anti-drilling.

4, the utility model since in the lock core pellet shot from a slingshot hole slot unique design circularize, and key must match with it, concavo-convex cooperation can enter bullet groove and lock could be opened; Therefore this lock can not only radially rotate, and also can move axially to be used for the axial direction locking.

5, the utility model is simple in structure, is applicable to various door locks, lock etc.

Concrete structure of the present utility model is provided by the following drawings:
