Background

The hinge is a mechanical structure used for connecting two solids and allowing relative rotation between the two solids. The hinge mainly comprises two hinged hinge sheets, can also be composed of movable components or foldable materials, but because the hinge is fixed in a hinged mode, the included angle between the two hinge sheets cannot be fixed by self. The hinge is mainly installed on a door and a window, and the door frame and the door are rotationally connected through the hinge sheet to realize the rotation opening and closing of the door. However, in practical use, some doors with special positions or special functions need to be kept in a normally closed state, such as a toilet door or a heat-preservation and cold-preservation door. Although automatic doors are sold in the market, most of the automatic doors are electric transverse doors or the electric transverse doors move through a hydraulic effect, the doors with the structures are often high in price and can be realized only by auxiliary energy, and the automatic doors are not suitable for wide popularization.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that current hinge structure is single, can only be used for rotating the connection, can not realize controlling the hinge contained angle.

The utility model provides a technical scheme that its technical problem adopted is: the elastic hinge comprises two hinged hinge sheets and an elastic piece, wherein two ends of the elastic piece are respectively connected with the two hinged hinge sheets, so that the two hinge sheets are vertically arranged.

Wherein, in the structure, the elastic parts are 1 to 3 and are uniformly arranged on the side wall of the hinged part of the two hinge sheets.

The structure also comprises a supporting rod, one end of the supporting rod is connected with the elastic piece, and the other end of the supporting rod is connected with the hinge shaft opposite to the middle of the elastic piece or the side wall of the hinge sheet.

Furthermore, the two elastic pieces connected with the supporting rod in the structure are positioned on two sides of the supporting rod, and the other ends of the elastic pieces are correspondingly connected with the hinge pieces.

Wherein, in the structure, the elastic part is a tubular spring.

Furthermore, the structure also comprises an arc-shaped guide rod, the guide rod is of a telescopic rod structure, and the elastic part is sleeved on the guide rod in a penetrating way.

Furthermore, the end part of the guide rod in the structure is hinged with the hinge plate ball.

The utility model has the advantages that: this structure does not use any energy to make the door close, and the installation is convenient, and is energy-concerving and environment-protective. Through set up the elastic component on articulated hinge piece, can keep two hinge pieces perpendicular through the elastic component, this kind of structure makes under the exogenic action, and two hinge pieces rotate relatively, and compression or tensile elastic component make take place elastic deformation. After the external force is withdrawn, the elastic part is restored under the action of elastic potential energy. When the door is naturally pushed open, the spring generates certain resistance to the hinge, and the hinge transmits force to the door, so that the door is forced to be automatically closed. And the spring can be dismantled when installing or changing, and is convenient and easy to install with ordinary hinge on the market, and the price is low.
