Description

Concentric shaft hinge

Technical Field

The utility model relates to a hinge technical field specifically is a concentric shaft hinge.

Background

Hinges are mechanical devices used for connecting two solids and allowing rotation between the two solids, and the hinges in furniture hardware fittings occupy important positions; the hinge generally comprises a second hinge, a first hinge and a pin shaft for connecting the second hinge and the first hinge, the first hinge is generally used for being fixed on a stand column, a frame or a wall body, and the second hinge is fixedly connected with the door, so that the door can rotate around the pin shaft to have two states of opening or closing. In the actual life process, because the second hinge turned angle of hinge does not have spacingly, when causing the door to rotate to open, easy and stand or automobile body contact around for the scar appears on the door, influences the customer and uses.

The existing hinge has poor degree of freedom, and the hinge is seriously abraded and easily damaged.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a concentric shaft hinge to solve the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a concentric shaft hinge, includes the round pin axle, it has hinge, door leaf hinge and door frame lower hinge on the door frame to sell epaxial cover, and the door leaf hinge is located the door frame on between hinge and the door frame lower hinge, stifled cap is installed to lower hinge bottom, be provided with the cladding bearing on the door frame between hinge and the door leaf hinge, be provided with the cladding bearing between door frame lower hinge and the door leaf hinge, the cladding bearing housing is on selling epaxial.

Preferably, copper sheets are arranged at two ends of the cladding bearing respectively, and the copper sheets are sleeved on the pin shaft.

Preferably, a set screw is installed on the hinge on the door frame, and an annular groove is formed in the position, located at the set screw, of the pin shaft.

Preferably, the cross section of the annular groove is arc-shaped.

Compared with the prior art, the beneficial effects of the utility model are that: the concentric axis hinge can be adjusted in 2 degrees of freedom relative to the other hinges.
