Abstract

The utility model discloses a reinforced structure for door lock, mainly comprising an outer lock part, an inner lock part and a lock core part, wherein the outer lock part comprises a drawing body, a lock shell and a lock head and is fixed at the outer side of the door; the inner lock part comprises a leaning body and a knob, and is locked with the outer lock part through a bolt and is fixed at the inner side of the door and locks the lock core part at the inner rim of the door; when the inner lock part and the outer lock part are locked at the inner side and the outer side of the door, the drawing body and the leaning body are relatively arranged at the inner edge of the door, a C-shaped reinforced plate is provided to reinforce the fixation intensity of the door plate; therefore, the structure of the door lock is more firm.

Description

The reinforced structure of door lock

Technical field

The utility model relates to a kind of door lock, relates in particular to a kind of reinforced structure of door lock.

Background technology

The framework of door is an important structure indispensable in the building system, raising along with the affluence and the quality of the life of economy, its form, pattern, material, structures etc. are all along with the trend in epoch changes, and the structure of door lock also is a member indispensable in the door leaf system, along with door bodily form formula, the difference of material, its form, structure is also had nothing in common with each other, see also Fig. 1, be common metal door leaf door latch structure commonly used shown in the figure, this door lock is that lock body is divided into outer lock part A and two structures of inner lock part B, locks respectively in door body both sides, and utilizes two pivot joint sleeve D to be located in a body inner edge, with fixing core C, make door lock possess the effect of locking.But, fixing because two lock body fixed structures of this door lock only depend on two pivot joint sleeve spiral shells to establish, be not enough to keep out slightly firmly knock in fact on its intensity and can destroy whole lock body easily.Therefore, the anxiety of real influential safety now is discussed below its shortcoming:

By as can be known shown in Figure 1, the lock knot mode of two lock bodies of this door lock, be to establish outer lock part and wear core with articulating the sleeve spiral shell, establish to the other end by two screw rod spiral shells again, with fixing inner lock part, hence one can see that, and two lock sections of this door lock are to utilize to articulate the sleeve indirect securement, so not only the steadiness of door lock is relatively poor, and, because articulate sleeve only the thread segment spiral shell establish to outer lock part, so its soundness is not good, as fiercelying attack with external force, must be easily with the outer lock part abate, moreover some dealer can be made a stay bolt into and directly wears alternative articulating sleeve, but it is not enough that its intensity is still disliked, and in addition improved necessity is arranged in fact.
