CN2482581Y - Anti-technical unlocking cylinder lock - Google Patents

Abstract

The utility model designs a night lock that can prevent against technical unlocking. The design proposal is as follows: the lock core is designed to be consisted of at least Part A and Part B with the same axis, relative marble holes are also respectively organized into groups on the two sections of the lock core. Meanwhile, at least one key slot that can be embedded with moveable billiards on the adjacent transect of the two lock core to ensure that no synchronous rotation happens in lock core A and lock core B when technical unlocking occurs with only a small and limited dislocation. When the technical unlocking occurs, if the lock core B is not rotated, the technique can not unlock the lock. The night lock is characterized in that the safety and reliability of the lock is enhanced, and the structure of the lock is not complicated; in addition, the normal unlocking has no differences with the existing night locks and the lock is easy to be used.

Description

The cylinder lock of anti-technical opening

The utility model belongs to lock, particularly a kind of cylinder lock of anti-technical opening.

The cylinder lock of prior art is the list of monolock core and organizes the structure that list formula symmetry is organized pellet shot from a slingshot more, the lock of this spline structure all can be opened lock (being called technical opening) from lockhole with special simple tool (non-lock key) and masterful technique under the situation of not destroying lock.The cylinder lock of prior art that Here it is exists one of dangerous reliable factor.

For solving the deficiencies in the prior art, the utility model has designed a kind of cylinder lock of anti-technical opening.Its design scheme is: by lock housing, spring support, spring, pellet shot from a slingshot, spring shield, lock core with pull out the cylinder lock that tongue constitutes, lock core is designed to two sections of A, the B of concentric at least, organizes into groups corresponding pellet shot from a slingshot hole equally respectively on the two-phase lock core.On two lock cores, be provided with spacing feather key separately, in case its axial displacement.Again on the adjacent cross section of two lock cores corresponding be provided with can embedding activity pellet shot from a slingshot at least one keyway, to reach the asynchronous rotation of core A when the technical opening, only can produce a small amount of and limited dislocation with core B.Such design guarantees promptly that this is locked in and has no effect when key operated, and is convenient equally with the lock of prior art.And once generation technique when opening, its technological means must be dialled rotation with lock core A section hook earlier, just has dislocation slightly with the generation of lock core B section, and technical tool promptly can not continue to go deep into lock core B section again and carry out hook and dial, guarantee that lock core B section is not rotated, this method promptly can not be opened this lock again.

Figure of description: be the cross-sectional view of the cylinder lock of anti-technical opening of the present utility model.

The exemplary embodiments of the cylinder lock of anti-technical opening of the present utility model is as follows:

Cylinder lock by lock housing (1), spring shield (2), spring support (3), spring (4), pellet shot from a slingshot (5), lock core (6) and group tongue (7) formation, lock core (6) is designed to two sections of A, the B of concentric at least, on the two-phase lock core, organizes into groups corresponding to spring (4) and pellet shot from a slingshot (5) pellet shot from a slingshot hole equally.Be provided with spacing cunning strong (8) on the two-phase lock core separately, in case its axial displacement.Again on the adjacent cross section of two-phase lock core corresponding be provided with can embedding activity pellet shot from a slingshot at least one keyway (9).This design scheme can be divided into two sections or multistage lock core (6) axially on be provided with one group or be arranged with the pellet shot from a slingshot holes of many groups corresponding to spring (4) and pellet shot from a slingshot (5).

The advantage of the spring lock of the anti-technical opening of the utility model design is, increased this lock Security reliability, and structure and uncomplicated, the normal unlatching with existing spring lock do not have any difference, Easy to use.

Claims (2)

1, the cylinder lock of anti-technical opening by lock housing (1), spring shield (2), spring support (3), spring (4), pellet shot from a slingshot (5), lock core (6), pull out tongue (7) and constitute, it is characterized in that lock core (6) wherein is made of for two sections A, B at least, and on A, B two-phase lock core, be laid with pellet shot from a slingshot hole equally corresponding to spring (4) and pellet shot from a slingshot (5), axial symmetric position is equipped with spacing feather key (8) on A, the B two-phase lock core, corresponding at least one keyway (9) that can embed draw key that is provided with on the adjacent cross section of A, B two-phase lock core.

2, the cylinder lock of anti-technical opening as claimed in claim 1 is characterized in that axially can being provided with one group or be arranged with the pellet shot from a slingshot holes of many groups corresponding to spring (4) and pellet shot from a slingshot (5) at A, B two-phase lock core (6).
