Abstract

The utility model discloses a multistage lock core prying-proof safety lock, which comprises a lock body, a lock core arranged in a lock core hole of the lock body as well as a tumbler assembly for controlling the lock core, wherein the lock core comprises a first-stage lock core fixed along the axial direction and a push lock core capable of to-and-fro motion along the axial direction and provided with a return spring, the push lock core is connected with a power input end of a linkage mechanism of the lock when protruding from the tail end of the lock core hole and releases locking under the reset state, and the key is right propped against the tumbler assembly when the push lock core is in the working state. The utility model provides a multistage lock core prying-proof safety lock with simple structure and good anti-theft effect.

Description

The anti-safety lock of dialling of multistage lock core

(1) technical field

The utility model relates to the anti-safety lock of dialling of a kind of multistage lock core, belongs to a kind of lockset of hardware class.

(2) background technology

No. 03217043.2 utility model patent of China Intellectual Property Office discloses the anti-safety lock of dialling of a kind of multistage lock core, and existing lockset has been carried out comparatively describing in a systematic way.Its disclosed lockset is made of lock body, prime lock core, back level lock core, work key and the key that resets, prime lock core and back level lock core are axially disposed within the lock core hole of lock body, be provided with work pellet shot from a slingshot and the anti-pellet shot from a slingshot of dialling on prime lock core and the back level lock core, anti-group pellet shot from a slingshot is positioned at the both sides of work pellet shot from a slingshot, the work key runs through the keyhole of prime lock core and back level lock core, and the key that resets only runs through the keyhole of prime lock core.Its anti-principle of dialling mainly utilizes many row's pellets shot from a slingshot to realize, arranges not only complex structure of pellet shot from a slingshot more, the cost height, and also fault rate also can improve, and in a single day break down, lockset just is difficult to open.This lockset has multistage lock core, and this multistage lock core lock core that is the rotation of coaxial setting, as long as push all pellets shot from a slingshot successively aside, still can open lockset.

(3) summary of the invention

Therefore, the utility model provides a kind of simple in structure at the above-mentioned defective of existing lockset, the anti-safety lock of dialling of the multistage lock core of good anti-theft effect.

The technical solution adopted in the utility model is:

The anti-safety lock of dialling of the multistage lock core of this programme, comprise lock body and the lock core of device in the lock body lock core hole, and the pellet shot from a slingshot group of control lock core, described lock core comprises vertically fixedly first order lock core and propelling lock core that can move back and forth vertically and that have back-moving spring, wherein advance lock core when leaning out the lock core hole tail end, to be connected with the link gear power intake of lockset, take off lock under the reset mode, and when advancing lock core in working order, key pushes up flat pellet shot from a slingshot group just.

Based on the technical solution of the utility model as can be known, the utility model adopts and advances this new type of component of lock core, makes to want to unblank not only to need rotational lock core, also will promote described propelling lock core and move to the link gear that correct position can drive lockset.Thereby, if stir first order lock core, owing to rotated this lock core, blocked propelling lock core thereafter so, just can't stir the propelling lock core; Even if advance lock core to be struck, but can't promote its motion, anti-theft effect is strengthened greatly.On the other hand, simple in structure, with low cost because this programme has only been used one group of pellet shot from a slingshot, be convenient to promote.

The anti-safety lock of dialling of above-mentioned multistage lock core, described pellet shot from a slingshot component be the first order pellet shot from a slingshot group corresponding with first order lock core and with the corresponding propelling pellet shot from a slingshot group of propelling lock core.

The end that described propelling lock core is connected with the lockset link gear is a rectangular protrusions, and accordingly, the lockset link gear is provided with rectangular channel.

(4) description of drawings

Fig. 1 is the anti-a kind of structural representation of dialling safety lock of the multistage lock core of the utility model.

Among the figure: 1, lock body, 2, first order pellet shot from a slingshot group, 3, first order lock core, 4, advance the pellet shot from a slingshot group, 5, advance lock core, 6, back-moving spring.

(5) specific embodiment

Specify structural principle of the present utility model below in conjunction with Figure of description:

With reference to explanation accompanying drawing 1, the anti-safety lock of dialling of the multistage lock core of present embodiment, comprise lock body 1 and the lock core of device in the lock body lock core hole, and the pellet shot from a slingshot group of control lock core, it is characterized in that: described lock core comprises vertically fixedly first order lock core 3 and propelling lock core 5 that can move back and forth vertically and that have back-moving spring 6, wherein advance lock core when leaning out the lock core hole tail end, to be connected with the link gear power intake of lockset, take off lock under the reset mode, and when advancing lock core in working order, key pushes up flat pellet shot from a slingshot group just.

For the ease of control, described pellet shot from a slingshot component be the first order pellet shot from a slingshot group 2 corresponding with first order lock core and with the corresponding propelling pellet shot from a slingshot group 4 of propelling lock core.

The end that described propelling lock core is connected with the lockset link gear is a rectangular protrusions, and accordingly, the lockset link gear is provided with rectangular channel, only that is to say that at ad-hoc location, both can form cooperation, do not rotating lock core before cooperating forming, just can't unblank, theftproof performance is further strengthened.

Claims

1. a multistage lock core prevents dialling safety lock, comprise lock body (1) and the lock core of device in the lock body lock core hole, and the pellet shot from a slingshot group of control lock core, it is characterized in that: described lock core comprises vertically fixing first order lock core (3) and the propelling lock core (5) that can move back and forth vertically and have back-moving spring (6), wherein advance lock core when leaning out the lock core hole tail end, to be connected with the link gear power intake of lockset, take off lock under the reset mode, and when advancing lock core in working order, key pushes up flat pellet shot from a slingshot group just.

2. the anti-safety lock of dialling of multistage lock core according to claim 1 is characterized in that: described pellet shot from a slingshot component for the first order pellet shot from a slingshot group (2) corresponding with first order lock core and with advance the corresponding propelling pellet shot from a slingshot group (4) of lock core.
