Abstract

The utility model provides a special-shaped hinge, including the hinge, hinged joint fixed plate and layer board, this spacing boss between fixed plate and the layer board, the spring is fixed respectively with the layer board both ends, the fixed plate is equipped with the regulation hole, the layer board is equipped with the arc limit, in operation, fix two hinges on the equipment that will use with the regulation hole, the arc mouth of two hinges is relative, when the plate falls down, fall on the arc mouth, relative arc mouth becomes circular and catches the plate, the effect plate through the hinge falls on the table surface of below, the effect of spring makes its resume, spacing boss restriction hinge open angle. The structure can automatically recover, and the two devices can be used for receiving objects such as a tray body and the like at the same time.

Description

Special-shaped hinge

Technical Field

The utility model belongs to the technical field of the hinge, concretely relates to special-shaped hinge.

Background

The hinge is a very common structure, but the rotation angle of the traditional hinge is 360 degrees, and the traditional hinge cannot be used for limiting certain special angles, so that the application range of the hinge is limited.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a special-shaped hinge which can be conveniently accepted and has the characteristic of automatic recovery.

In order to realize the purpose, the utility model discloses a technical scheme is:

the special-shaped hinge comprises a hinge, a fixing plate and a supporting plate which are connected through the hinge, a limiting boss is arranged between the fixing plate and the supporting plate, springs are respectively fixed at two ends of the supporting plate, adjusting holes are formed in the fixing plate, and arc-shaped edges are formed in the supporting plate.

The two springs are adopted, and the metal strips extending out of the springs clamp the fixing plate.

The fixed plate and the supporting plate are kept vertical under the action of no external force under the combined action of the spring and the limiting boss.

The utility model has the advantages that:

the structure can automatically recover, and the two devices can be used for receiving objects such as a tray body and the like at the same time.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a partial schematic view of the present invention.

Fig. 3 is a partial schematic view of the present invention.

Wherein, 1 is a hinge; 2 is a fixed plate; 3 is a supporting plate; 4 is a spring; 5 is an adjusting hole; 6 is an arc edge; and 7, a limiting boss.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the special-shaped hinge comprises a hinge 1 and is characterized in that the hinge 1 is connected with a fixing plate 2 and a supporting plate 3, a limiting boss 7 is arranged between the fixing plate 2 and the supporting plate 3, a spring 4 is respectively fixed at two ends of the supporting plate 3, the fixing plate 2 is provided with an adjusting hole 5, and the supporting plate 3 is provided with an arc-shaped edge 6.

The number of the springs 4 is two, and the metal strips extending out of the springs clamp the fixing plate 2.

The fixed plate 2 and the supporting plate 3 are kept vertical under the action of no external force under the combined action of the spring 4 and the limiting boss 7.

The utility model discloses a theory of operation is:

when the dish is in work, the two hinges are fixed on equipment to be used through the adjusting holes, the arc-shaped openings of the two hinges are opposite, when the dish falls down, the dish falls on the arc-shaped openings, the opposite arc-shaped openings form a circle to receive the dish, the dish falls on a working table surface below through the action of the hinges, the dish is recovered under the action of the springs, and the limiting bosses limit the opening angle of the hinges.
