Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a threading hinge with torque force. Background Art

[0002] A hinge is a mechanical device used to connect two solid bodies and allow them to rotate relative to each other.

[0003] The hinges in the prior art are generally divided into general hinges, spring hinges, door hinges, electromechanical cabinet hinges, heavy-duty hinges, special-shaped hinges, table hinges, flap hinges, glass hinges, etc. At present, there is a lack of hinges with torque force in the market. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems existing in the background technology. To this end, a torque threading hinge is provided. After the locking nut is locked, the conical spring piece generates pressure to compress the friction plate in the middle, thereby increasing the friction force and generating torque force.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A torque threading hinge, comprising a hinge body, a hinge fixing plate and a locking nut;

[0007] A spring sheet group and a friction sheet group are placed between the hinge body and the hinge fixing sheet, adjacent spring sheets of the spring sheet group are in surface contact with each other, adjacent friction sheets of the friction sheet group are in surface contact with each other, and adjacent spring sheets and friction sheets are in surface contact with each other;

[0008] The threaded portion of the hinge body sequentially penetrates a plurality of spring sheets of the spring sheet group, a plurality of friction sheets of the friction sheet group and a hinge fixing sheet and is thread-locked with a locking nut.

[0009] Through the above technical solution, after the locking nut is locked, the spring plate group between the hinge body and the hinge fixing plate generates pressure to compress the friction plate group, thereby increasing the friction force of the friction plate group and then generating torque.

[0010] The following is a technical solution further defined by the present utility model, wherein the shrapnel group includes two conical shrapnel, the conical openings at both ends of the conical shrapnel are respectively a large-diameter conical opening and a small-diameter conical opening, the small-diameter conical openings of the two conical shrapnel are close to each other, and the large-diameter conical openings are far away from each other, the two conical shrapnel are respectively a first conical shrapnel and a second conical shrapnel, and the first conical shrapnel and the second conical shrapnel are symmetrically arranged.

[0011] Through the above technical solution, the specific structure of the spring sheet group is further limited. The first conical spring sheet and the second conical spring sheet are symmetrically arranged and squeeze each other to generate pressure on the friction plate group.

[0012] The following is a technical solution further defined by the present invention, wherein the friction plate group includes a first single-sided friction pad, a double-sided friction plate and a second single-sided friction pad which are abutted in sequence, the friction surface of the first single-sided friction pad abuts against the hinge fixing plate, and the friction surface of the second single-sided friction pad abuts against the conical spring plate of the spring plate group.

[0013] Through the above technical scheme, the specific structure of the friction plate group is further limited. Both sides of the friction plate are friction surfaces. The first single-sided friction pad and the second single-sided friction pad both have a single friction surface. The friction surface is provided with friction patterns to increase friction. However, for those that are not friction surfaces, they also have friction, but the friction is smaller.

[0014] The following is a technical solution further defined by the present invention: a gasket is placed between the inner side of the stepped abutment of the hinge body and the conical spring of the spring group. A plurality of screw holes are opened along the circumferential direction on the outer side of the stepped abutment of the hinge body, and a plurality of screw holes are opened along the circumferential direction on the hinge fixing sheet. A hollow threading hole is opened along the axial direction of the threaded portion of the hinge body.

[0015] Through the above technical solution, after the hinge body and the hinge fixing plate are fixed with screws, they can be rotated 360 degrees. There is a hollow wire threading hole in the middle of the hinge body, so that the wire can pass through the middle.

[0016] Compared with the prior art, the utility model has the following technical effects:

[0017] The utility model arranges a spring plate group and a friction plate group between the hinge body and the hinge fixing plate, so that the elastic force generates a compressive force, which then increases the friction force and finally generates a torque force, so that the hinge product of the utility model has a torque force, which makes up for the market defects and has a larger market space; the whole product has a threading hole in the middle, through which the wire can pass, which is conducive to wiring.
