Abstract

The utility model discloses a door hinge, which comprises a hinge shaft. A fixed hinge and a door hinge are rotationally connected on the hinge shaft. A steel bushing is arranged outside the hinge shaft; one end of the steel bushing is fixedly connected on the fixed hinge and an extension section is arranged at the other end thereof after the other end thereof goes round the hinge shaft; the extension section and the fixed hinge form an included angle more than 90 degrees; a magnetic attracting device is arranged on the extension section and comprises at least two magnets with a structure of a big end and a small end; a magnet mounting groove with a structure of a big end and a small end is arranged on the extension section and corresponds to the number of the magnets; and the small end of the magnet mounting groove is arranged on one side close the door hinge. The door hinge of the utility model can better solve the problem that a structure used for positioning the magnet on the steel bushing is complex, the forming and processing requirement is high and the magnet is easily damaged. The door hinge of the utility model can be conveniently installed and can not fall off easily.

Description

A kind of door hinge

Technical field

The utility model relates to a kind of mounted component, is specifically related to a kind of door hinge.

Background technology

When installing, door need door be fixedlyed connected with doorframe by door hinge, hinge page or leaf about present door hinge comprises, about hinge page or leaf be provided with through hole, the through hole attachment screw with about hinge page or leaf be separately fixed on door and the doorframe, be provided with the unlatching that door-inhale is used for fixing on the wall usually assembling is finished after, though can play fixation, but door-inhale outwards has elongated end, fracture easily, and shut behind the door that the people runs into door-inhale easily because of carelessness, not only injure human body but also damage door-inhale because close the door overweight.For this reason, the applicant has applied for that on October 26th, 2007 name is called a kind of utility application of door hinge, application number is 200720192217.2, it is provided with steel bushing outside hinge, on steel bushing, be provided with magnet, can save the installation of door-inhale like this, keep the attractive in appearance of metope, help sweeping health simultaneously, and this door hinge cost is low, but the location of its magnet is cumbersome, and its structure of structure that is used for phase magnet on the steel bushing is relatively complicated, processing and forming is had relatively high expectations, and magnet also damages than being easier to.

The utility model content

Technical problem to be solved in the utility model just provides a kind of door hinge, and it is relatively complicated to solve its structure of structure that is used for phase magnet on the steel bushing, the problem that processing and forming is had relatively high expectations and magnet damages easily.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of door hinge, comprise hinge, switching has fixing hinge page or leaf and door hinge page or leaf on the hinge, described hinge also is provided with steel bushing outward, steel bushing one end is fixed on the fixing hinge page or leaf, the steel bushing other end is provided with the extension after walking around described hinge, described extension is an angle that is not less than 90 degree with fixing hinge page or leaf, described extension is provided with the magnetic device, it is characterized in that: described magnetic device is made up of the magnet of two concentric reducer structures at least, described extension is provided with the magnet mounting groove with the concentric reducer structure of magnet respective amount, and the little head end of magnet mounting groove is arranged on the side near door hinge page or leaf.

Preferably, the angle between described extension and fixing hinge page or leaf is 90 degree, and the extension is parastate with door hinge page or leaf, and described door hinge page or leaf just contacts magnet of living in when door hinge page or leaf becomes 90 to spend with described fixing hinge page or leaf.

Preferably, the angle between described extension and fixing hinge page or leaf is 180 degree, and described extension is parastate with fixing hinge page or leaf, and described door hinge page or leaf just contacts magnet of living in when door hinge page or leaf becomes 180 to spend with described fixing hinge page or leaf.

Preferably, described magnet is wedge type, round platform or stepped ramp type structure, is convenient to processing and installation, and is also more firm.

Preferably, described steel bushing is arranged on the stage casing of hinge.

The utility model can well solve the problem that its structure of structure is relatively complicated, processing and forming is had relatively high expectations and magnet damages easily that is used for phase magnet on the steel bushing owing to adopted technique scheme, and magnet is easy for installation, difficult drop-off.
