Abstract

The utility model discloses a door gemel, including a gemel base which is fixed in a door framework and a gemel which is fixed with the door, the gemel rotatedly flexibly connected on the gemel base through a rotation shaft, the utility model is characterized in that the side where the gemel is rotatedly flexibly connected with the gemel base is provided with a shaft housing, the upper edge and the lower edge of the shaft housing are provided with symmetrical L shape slots, the rotation shaft is composed of two sections of short rotation shafts which are symmetrically respectively provided with a small stick, the small stick passes through the L shape slots, a pressure spring is provided between the two short rotation shafts. Compared with the prior art, the utility model has the advantages of convenient loading, unloading and maintenance as well as a bigger rotation angle of the door.

Description

A kind of door hinge

Technical field:

The utility model relates to a kind of door hinge.

Background technology:

Existing built-in door hinge in doorframe mainly is made of a hinge that is fixed in hinge seat in the doorframe, be fixed together with door, hinge is the U shape, one end of hinge is fixed together with door by fastening on it, and the other end rotates by rotating shaft and is actively socketed on the hinge seat.This kind door hinge is because after the assembling, hinge seat, hinge are fixed together, very inconvenient when door being installed in doorframe by door hinge, and, after door was installed in doorframe, because door hinge is securely fixed on doorframe and the door, therefore dismounting, maintenance were very inconvenient, in addition, the hinge of U shape has limited the rotational angle of door.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of installation, dismounting, easy to maintenance, the bigger door hinge of door rotational angle.

The utility model is to realize like this, a hinge that comprises the hinge seat that is fixed in the doorframe, is fixed together with door, hinge rotates by rotating shaft and is actively socketed on the hinge seat, its special feature is that hinge and hinge seat rotate that end that is movably connected and be provided with axle sleeve, the both sides up and down of axle sleeve are provided with the L shaped groove of symmetry, and rotating shaft is made of two brachymemma rotating shafts, and symmetry respectively is provided with a small sticks in the two short rotating shafts, small sticks passes L shaped groove, is provided with compression spring between two short rotating shafts.During use, earlier hinge seat, hinge are separately fixed on doorframe, the door, axle sleeve is compressed in the short rotating shaft of on the hinge two and be stuck in by small sticks on the translot of L shaped groove, two short rotating shafts can not be stretched out outside the axle sleeve, then hinged door is moved on on the doorframe, make hinge face toward hinge seat, stir small sticks then, the translot that makes small sticks leave L shaped groove enters vertical slot, like this, under the effect of compression spring, two short rotating shafts are ejected outer also rotation of axle sleeve and are actively socketed on the hinge seat.

Here, in order to add the angle that the gate rotates, hinge is the trapezoidal shape that does not have the base.Because the hinge both sides of trapezoidal shape are horn-like, make hinge side end away from doorframe, like this, the stationary plane of hinge side end can bend to the doorframe direction, thereby has increased the angle that door rotates.

Compared with the prior art the utility model owing to adopted telescopic a pair of short rotating shaft and hinge to be the trapezoidal shape that does not have the base, therefore, has installation, dismounting, easy to maintenance, the bigger advantage of door rotational angle.

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

Fig. 2 is user mode figure of the present utility model.

The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

As shown in the figure, the utility model comprises the hinge seat 2 that is fixed in the doorframe 1, by stationary plane 3 and door 4 hinges that are fixed together 5, hinge 5 rotates by rotating shaft 6 and is actively socketed on the hinge seat 2, its special feature is the trapezoidal shape that hinge 5 is does not have the base, hinge 5 rotates that end that is movably connected with hinge seat 2 and is provided with axle sleeve 7, the both sides up and down of axle sleeve 7 are provided with the L shaped groove 8 of symmetry, rotating shaft 6 is by two

brachymemma rotating shaft

9a, 9b constitutes, two short rotating shaft 9a, the last symmetry of 9b respectively is provided with a

small sticks

10a, 10b,

small sticks

10a, 10b passes L shaped groove 8, two short rotating shaft 9a, be provided with compression spring 11 between 9b.

Here, maintenance is connected with hinge axis orifice ring 12 on the hinge shaft hole of hinge seat 2 for convenience, and the short rotating shaft 9a of the anti-wear performance of hinge axis orifice ring and hardness ratio, 9b want high, and

small sticks

10a, 10b screw thread are screwed on short rotating shaft 9a, the 9b.Like this, after long-time the use, short rotating

shaft

9a, 9b wearing and tearing earlier, and hinge axis orifice ring 12 is not easy wearing and tearing, at this moment, only needs

small sticks

10a, 10b are disassembled, and just can change short rotating

shaft

9a, 9b.

Claims

1, a kind of door hinge, a hinge that comprises the hinge seat that is fixed in the doorframe, is fixed together with door, hinge rotates by rotating shaft and is actively socketed on the hinge seat, it is characterized in that hinge and hinge seat rotate that end that is movably connected and be provided with axle sleeve, the both sides up and down of axle sleeve are provided with the L shaped groove of symmetry, and rotating shaft is made of two brachymemma rotating shafts, and symmetry respectively is provided with a small sticks in the two short rotating shafts, small sticks passes L shaped groove, is provided with compression spring between two short rotating shafts.

2, door hinge according to claim 1 is characterized in that the trapezoidal shape that hinge is does not have the base.

3, door hinge according to claim 1 and 2 is characterized in that being connected with the hinge axis orifice ring on the hinge shaft hole of hinge seat, the short rotating shaft of the anti-wear performance of hinge axis orifice ring and hardness ratio wants high, and the small sticks screw thread is screwed in the short rotating shaft.
