Description

Enhancement mode bicylinder locks bolt component

Technical field

This utility model is related to lock technology field, the more particularly, to bolt component of bicylinder lock.

Background technology

Commercially available bicylinder door lock carrying out opening and during lock operation all with the assembly of key rotation lock core and gear, by Gear drive cylinder tongue and dead bolt drag the assembly of body；And dead bolt drags body due to due to its shape and processing technique, can only adopt Zinc alloy material makes, but the intensity of zinc alloy material is that dead bolt adopts zinc alloy material to make, directly far from compared with steel Connect the safety that have impact on lockset and service life.

Utility model content

This utility model is directed to the problems referred to above of the prior art, provides a kind of enhancement mode bicylinder lock bolt component, its Structure is simple, and intensity is high, and long service life is safe and reliable.

The technical scheme that this utility model is adopted is as follows:

Enhancement mode bicylinder locks bolt component, drags body including dead bolt, and dead bolt drags riveting with it to have mold insert, the u shape on mold insert Groove both sides carry several draw-in grooves；

Further, mold insert is riveted on dead bolt and drags on the step of body, and mold insert and dead bolt drag body in the same plane；

Further, mold insert adopts steel plate materialses.

The utility model has the advantage of: structure is simple, dead bolt drag with mold insert adopt steel plate to make, service life Long, safe and reliable.

Brief description

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is use state figure of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described.

As shown in Figure 1 to Figure 3, this utility model includes dead bolt and drags body 1, and dead bolt drags riveting on body 1 to have mold insert 2, on mold insert 2 U shape groove both sides carry several draw-in grooves, as shown in figure 3, when actually used, described draw-in groove is engaged with the tooth on gear 4；Mold insert 2 It is riveted on dead bolt to drag on the step of body 1, for ease of installing mold insert 2, described step is arranged at one end that dead bolt drags body 1, by punching Mold insert 2 and dead bolt are come out boldly and 1 are fixed on one, due to having mill using process middle gear 4 to described draw-in groove by the mode being riveted Damage, mold insert 2 adopts steel plate materialses to make, and can increase the intensity of mold insert 2, extends the service life of lockset；

Mold insert 2 and dead bolt drag body 1 in the same plane it is ensured that whole dead bolt is being divided into mold insert 2 and dead bolt drags After body 1 two parts, the shape invariance of dead bolt, dead bolt drags one end of body 1 to carry several cylinder dead bolts 3；Mold insert 2 is with regard to described u The symmetrical structure of shape groove, can make the concordance of the dead bolt former lock bolt structure shape after improvement；

As shown in figure 3, when actually used, tapered end slide block 6 is fixed on housing 7, tapered end 5 is fixed on tapered end slide block 6, tooth Wheel 4 is fixed on tapered end 5, and tapered end 5 can rotate, when needing unlocking or locking, rotational lock head 5, and gear 4 can be with tapered end 5 Rotate, the tooth on gear 4 is engaged with the described draw-in groove on mold insert 2, so that mold insert 2 is dragged with dead bolt and slide along tapered end slide block 6 together with body 1 Dynamic, thus doing stretching motion with cylinder tongue 3 in the in the hole of panel 8, reach the purpose of unlocking or locking.

Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model is limited Scope, referring to claim, within protection domain of the present utility model, can make any type of modification.
