Abstract

The utility model relates to a linkage piece used in a door hinge. One end of the linkage piece is provided with a first shaft hole connected with a rotating piece of the door hinge, the other end of the linkage piece is provided with a second shaft hole connected with a built-in fitting of the door hinge, a compressing piece for compressing a torsion spring is arranged at the position where the linkage piece fits the torsion spring, and the utility model is characterized in that the compressing piece is in a triangular shape. The utility model has high force-sustaining strength and simple structure, cannot be compressed broken by the torsion spring, can be produced easily, and rotates smoothly during use.

Description

The moving part that door hinge is used

Technical field

The utility model relates to the moving part that a kind of door hinge is used.

Background technology

The moving part that existing door hinge is used, the one end is established first axis hole that is connected with the tumbler of door hinge, the other end is provided with second axis hole that is connected with the fixture of door hinge, is provided with the extrusion of an extruding torque spring on moving part and position that torque spring cooperates; This extrusion is a crushing block that makes progress, and as shown in Figure 1, 2, its stressed strength ratio is relatively poor, and grown service time, and is disconnected by the torque spring extruding easily, influences the application life of entire product, produces inconvenience, and rotation has some setbacks.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of force intensity that is subjected to good, can be disconnected by the torque spring extruding, to produce easily, and the connection that the reasonable a kind of door hinge of result of use is used is moving.

In order to achieve the above object, the utility model is to realize like this, it is the moving part that a kind of door hinge is used, the one end is established first axis hole that is connected with the tumbler of door hinge, the other end is provided with second axis hole that is connected with the fixture of door hinge, is provided with the extrusion of an extruding torque spring on moving part and position that torque spring cooperates; It is characterized in that described extrusion shape triangular in shape.

Described extrusion and moving part are an integral body, and extrusion punching stretch on moving part forms.

The utility model advantage compared with prior art is, is subjected to force intensity good, can be disconnected, simple in structure by the torque spring extruding, produce easily, and rotate smooth and easy during use.

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is the A-A sectional view of Fig. 3;

Fig. 5 is the structural representation that is installed on the door hinge of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

Shown in Fig. 3 to 5, it is the moving part that a kind of door hinge is used, the one end is established first axis hole 22 that is connected with the tumbler 3 of door hinge, the other end is provided with second axis hole 24 that is connected with the fixture 5 of door hinge, on moving part and position that torque spring 4 cooperates, be provided with the extrusion 23 of an extruding torque spring, this extrusion shape triangular in shape.In the present embodiment, during production, connecting two slits 21 of left side stamping-out that are positioned at second axis hole on moving 2, promptly forming the extrusion that is triangular shape partly up stretching in the middle of the slit.During use, because extrusion is triangular in shape, its leg-of-mutton top extruding torque spring 4, it can bear big extruding force, can not break, and uses also more smooth and easy simultaneously.

Claims (2)

1, the moving part used of a kind of door hinge, the one end is provided with first axis hole that is connected with the tumbler of door hinge, the other end is provided with second axis hole that is connected with the fixture of door hinge, is provided with the extrusion of an extruding torque spring on moving part and position that torque spring cooperates; It is characterized in that described extrusion (23) shape triangular in shape.

2, the moving part of a kind of hinge usefulness according to claim 1 is characterized in that described extrusion (23) and moving part (2) are an integral body, and extrusion punching stretch on moving part forms.
