Abstract

The utility model discloses a door hinge with anti-collision function, which comprises a door box, a shell, an internal rocker arm, an external rocker arm and a torsion spring, wherein one ends of the internal rocker arm and the external rocker arm are both hinged with the door box, the other ends of the internal rocker arm and the external rocker arm are both hinged with the shell, a first magnet is arranged at the bottom of the door box, the external rocker arm is provided with a second magnet that is homopolar with and opposite to the first magnet after the second magnet is closed. After improvement, when a door leaf is closed, as the repellent of the first magnet and the second magnet, buffer is generated when the door leaf is about to collide with a door frame, the closer the magnet distance of two times is, the larger repellent is generated, so that the occurrence of rigid collision can be effectively avoided so as to protect a door structure.

Description

A kind of door hinge with crashproof function

Technical field:

The utility model relates to a kind of door hinge with crashproof function.

Background technology:

The door hinge of conventional art includes a box, housing, inner rocker arm, outer rocker arm and torsion spring, it is hinged with the door box that inner rocker arm and outer rocker arm are all distinguished an end, the other end and housing are hinged, when closing, at inner rocker arm, under the acting in conjunction of outer rocker arm and torsion spring, door leaf can be realized quick closedown, but this quick closedown has brought other problem, the later stage of closing motion, can not fan the device that produces buffering effect owing to have to be provided with, cause outer rocker arm striking door box bottom, and then cause the door leaf doorframe that clashes, send big noise or damage the door leaf plate, use after after a while, even can cause occurring getting loose between door hinge and door leaf and the doorframe.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of door hinge with crashproof pooling feature to be provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of door hinge with crashproof function, include a box, housing, inner rocker arm, outer rocker arm and torsion spring, it is hinged with the door box that inner rocker arm and outer rocker arm are all distinguished an end, the other end and housing are hinged, be provided with first magnet in the bottom of door box, on outer rocker arm, be provided with closed back and the first magnet homopolarity, second magnet in opposite directions.

After the improvement, when door leaf cuts out, owing to be subjected to the repulsive interaction of first magnet and second magnet, when door leaf will knocking door case, produce buffering, twice magnet distance is near more, and the repulsion of generation is big more, effectively avoids the generation of rigid collision, the shutter structure.

Description of drawings:

Fig. 1 is the structural representation of the utility model door hinge.

The specific embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

The door hinge that present embodiment has crashproof function includes a box 1, housing 2, inner rocker arm 3, outer rocker arm 4 and torsion spring (not shown), it is hinged with door box 1 that inner rocker arm 3 and outer rocker arm 4 are all distinguished an end, the other end and housing 2 are hinged, be provided with first magnet 5 in the bottom of door box 1, Rocker arm 4 is provided with closed back and first magnet, 5 homopolarities, second magnet 6 in opposite directions outside.

The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
