Abstract

The utility model relates to an improved structure of the lockset, which is characterized in that the locking core is safely hidden in the casing of the lockset. A locking core chamber is arranged in the casing of the lockset, and one side surface of the locking core chamber is provided with a locking hole whose size and shape are same with the size and the shape of the transversal profile of the key. The other side surface is provided with a column trough which is used to contain the locking core, and the side surface of the inner wall of the column body is provided with a braking ditch. The locking core is provided with a support post and a four directional locking sheet group. Because the excess space of the locking hole is eliminated, the lockset is prevented from being opened through an improper approach.

Description

Lock with built-in lock core

The utility model relates to a kind of structure-improved of lockset, especially refer to the lockset structure that a kind of door leaf uses, core wherein is hidden in the lockset housing, and has a centre strut and have the lock sheet groups etc. of four direction, with the redundant space of elimination lockhole, thereby prevent means opener improperly.

At present, the lock core structure of common lockset all has part to expose, and can directly be seen the rotation of core by the outside, and what become at the middle vacancy of lockhole in addition has a bigger space, and general lock sheet groups is unidirectional or corresponding break-in person.

In view of this, the purpose of this utility model provides a kind of core built-in lock, with core be hidden in fully in the lockset housing, and the redundant space of borrowing its centre strut to eliminate lockhole, and the key of unblanking is cylindrical hybrid with tooth plate shape, just can unblank.

The purpose of this utility model is achieved in that it mainly comprises lockset housing, core, affects plate, spring bolt mechanism and inboard unlocking mechanism wherein have a core chamber among the lockset housing, the lockhole that this one side, core chamber has key section size shape, and the another side is the cylinder groove of ccontaining core and is provided with the braking ditch on the inwall side of cylinder groove; Core has pillar and four-way lock sheet groups.

Owing to adopt such scheme, can prevent that improper means from unblanking, reach security purpose.

Below in conjunction with drawings and Examples the utility model is further specified.

The three-dimensional exploded view of Fig. 1 the utility model embodiment.

The sectional drawing of Fig. 2 the utility model embodiment.

The stereogram of Fig. 3 the utility model embodiment.

Local form's stereogram of Fig. 4 the utility model embodiment.

Consult shown in Figure 1ly, main structure of the present utility model comprises lockset gas 1, core 2, affects plate 3, spring bolt mechanism 4 and inboard unlocking mechanism 5 equal to form; Wherein among lockset housing 1, has a core chamber 11, these core chamber 11 1 sides (front) have the lockhole 12 of the cross section size and shape of key, and opposite side (back side) for opening greatly can ccontaining core 2 cylinder groove 13, and on the inwall side of cylinder groove 13, be provided with several braking ditch 14; In addition, core 2 is to have a pillar 21 in the central, and outside this core 2, place and be provided with four-way formula lock sheet groups 22, and this lock sheet groups 22 is to form with eight similar locking plates 221, the control form that wherein comprises two kinds of different key systems (cylindrical with tooth plate shape two kinds), and each locking plate 221 outwardly directed lug 222 of above-mentioned lock sheet groups 22 can embed respectively in the braking ditch 14 of lockset housing 1, to form the state that core can't rotate arbitrarily.

If during above-mentioned tectonic association, consult Fig. 2 and shown in Figure 3, at first general spring bolt mechanism 4 is fixed on the door leaf 7, core 2 then elder generation is inserted in its core chamber 11 by lockset housing 1 back side, and it is fixing with housing cover 15 sealings of lockset, this core 2 is hidden in the lockset housing 1, core 2 trailing edges fix one affect plate 3 after, above-mentioned combination is packed into wherein (in the present embodiment by the lateral surface of this door leaf 7, in addition with an escutcheon 8 liners in door leaf 7 and lockset housing 1 between), and make and affect plate 3 to pass spring bolt mechanism 4 breaker slots 41 corresponding with it, at last with inboard unlocking mechanism 5 suits thereon at the opposite side of door leaf 7, and will screw with lockset housing 1 and be fixed into one with screw 8, be connected on the door leaf 7, and make these inboard unlocking mechanism 5 interlocks above-mentioned affect plate 3.

If above-mentioned structure, consult shown in Figure 4, when the utility model is used in combination, only can see the section construction of the centre strut 21 and the locking plate 221 of built-in core 2 by lockhole 12 from the front of this lockset housing 1, yet, the redundant space that can borrow centre strut 21 to eliminate lockholes 12 is avoided choosing out the lock sheet groups 22 of this lockset and unblanking with other thing; Wherein lock sheet groups 22 is the four-way formula structures that mix with tooth plate shape with cylindrical again, so must make the arrangement form of untiing lock sheet groups 22 of vertical direction and horizontal direction simultaneously, could open this lockset, and the utility model is built-in because of core 2, has a centre strut 12 again, cause the rotary state that to see core 2, and there are not enough spaces to stretch into the lock sheet groups 22 of choosing out the four-way formula with other thing of the key 6 of non-unlatching lockset, so the utility model can prevent more effectively that other people from choosing with improper means and unblank, to reach purpose of safety.

Claims

1, a kind of core built-in lock comprise lockset housing, core, affect plate, spring bolt mechanism and inboard unlocking mechanism; It is characterized in that: have a core chamber among the lockset housing, the lockhole that this one side, core chamber has key cross section size shape, and the another side is the cylinder groove of ccontaining core, and on the inwall side of cylinder groove, be provided with the braking ditch; Core has pillar and four-way lock sheet groups.

2, by the described core built-in lock of claim 1, it is characterized in that: the pillar of above-mentioned core in central part, lock sheet groups at peripheral position, this lock sheet groups comprises the control form of two kinds of different key systems, and the horse ear of each locking plate can embed respectively in the braking ditch of lockset housing.
