Abstract

The utility model provides a theft-proof cylinder switch which is the improvement on the basis of a cylinder switch of the original cylinder lock. One or a plurality of anti-theft layers are added between a lock shell and a lock core; each anti-theft layer is formed by that a cylinder is permanently fixed on the lock core or the lock shell through a cylinder; the cylinder head of the unlocking point of the cylinder is designed into a wedge shape or a step shape. An anti-theft cylinder lock with the structure can prevent technique unlocking, can not be unlocked without a key of the anti-theft cylinder lock, has good anti-theft performance, and is particularly suitable for important departments, such as security cabinets, high class cars, anti-theft doors, etc. The utility model has a broad application range. The anti-theft cylinder switches can be assembled to the cylinder locks of different types and purposes.

Description

The anti-theft billiards switch

The utility model relates to a kind of lock, especially a kind of anti-theft billiards switch of cylinder lock.

Production at present and the cylinder lock that uses, though it is multifarious, different but pellet shot from a slingshot construction of switch that it is inner all is identical, promptly generally be divided into two-layer, one deck is a lock housing, one deck is a lock core, adorn a spring in the pellet shot from a slingshot hole, two pellets shot from a slingshot (lock housing pellet shot from a slingshot and lock core marble), contact surface between lock housing and the lock core is a release line, and the pellet shot from a slingshot head between two pellets shot from a slingshot is an opening point, and its opening point pellet shot from a slingshot head is cylindrical, it has two angles from plan view, in the time of need not key operatedly being technical opening, because the insert rotational lock core, release line will form a small stair, the pellet shot from a slingshot that is pushed is easy to rest on the small stair, the pellet shot from a slingshot switch just is in the enable possition, therefore causes this lock to open easily, and does not have anti-theft feature.

The purpose of this utility model provides does not a kind ofly have key just can not open, and theftproof is good, and structure is uncomplicated, the anti-theft billiards switch of applied range.

The utility model is to improve on the pellet shot from a slingshot switch basis of original cylinder lock, between lock housing and lock core, increase one or more layers theft-proof layer, theft-proof layer is to constitute with permanent being fixed on lock core or the lock housing of pellet shot from a slingshot, and the opening point pellet shot from a slingshot head of pellet shot from a slingshot is designed to wedge shape or step.

Adopt the antitheft sylinder of this structure to open by defense technique, there is not this lock key just not open, even advanced person's such as MASTERKRY, " Unlocking gun " unlocking tool also can't be opened, theftproof performance is fabulous, being specially adapted to some important departments uses, as safety cabinet, sedan limousine, security door etc., and the utility model applied range, the anti-theft billiards switch can be formed the cylinder lock of different purposes of all kinds.

Elaborate below in conjunction with accompanying drawing.

Shown in the figure, 1. lock core 2. theft-proof layers 3. lock housings 4. springs 5. wedge shape pellet shot from a slingshot heads 6. release line 7. anti-theft wires 8. cylinder-shaped marble heads 9. pellets shot from a slingshot 10. step pellet shot from a slingshot heads

The utility model has kept lock housing, lock core and the pellet shot from a slingshot of original cylinder lock, increases one or more layers theft-proof layer (2) between lock housing (3) and lock core (1); Theft-proof layer is to constitute with permanent being fixed on lock core or the lock housing of pellet shot from a slingshot; The opening point pellet shot from a slingshot head of cylinder pin is not counted wedge shape (5) or step (10).The position of theft-proof layer (2) also can be exchanged with lock core (1).

Principle and process that the utility model defense technique is opened are: when the technical opening rotational lock core, the pellet shot from a slingshot aperture of anti-theft wire (7) and release line (6) all can misplace, and small stair occurs.When the promotion pellet shot from a slingshot is reciprocating, small stair on the release line can not be put wedge shape pellet shot from a slingshot head (because that some of being put is easily pruned), and the small stair of anti-theft wire is easy to columniform anti-theft billiards head (8) is put (seeing Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8), at this moment opening point is not also to release line (seeing Fig. 5,6) or surpassed release line (seeing Fig. 3,4), that is to say when pellet shot from a slingshot is put, the anti-theft billiards switch is not on the position of unlatching, and still locates closed condition.Originally be in the anti-theft billiards switch of opening, will become closed condition (seeing Fig. 7,8) once technical opening.Step pellet shot from a slingshot head is easy to rest on the release line, and what put is the step of pellet shot from a slingshot, is not opening point, so although put, but the anti-theft billiards switch still is in closed condition (seeing Fig. 9,10).In the process that defense technique is opened, anti-theft billiards head and anti-theft wire play a key effect, and they fix and be locked in closed condition to the anti-theft billiards switch, thereby make the anti-theft billiards switch reach the purpose that defense technique is opened.

Claims

1, a kind of anti-theft billiards switch is made up of lock housing (3), lock core (1) and cylinder pin (9).It is characterized in that:

A. between lock housing (3) and lock core (1), increase one or more layers theft-proof layer (2); Theft-proof layer is to constitute with permanent being fixed on lock core or the lock housing of pellet shot from a slingshot;

B. the opening point pellet shot from a slingshot head of cylinder pin is designed to wedge shape (5) or step (10).

2, anti-theft billiards switch as claimed in claim 1 is characterized in that: the position of theft-proof layer (2) also can be exchanged with lock core (1).
