Embodiment approach

[0034] As an embodiment of the present invention, the hydraulic mechanism 4 is composed of a hydraulic bladder 41 and a conduit assembly 42, the hydraulic bladder 41 is fixedly connected to the side wall at the end of the fixing groove 3 away from the opening, and the conduit assembly 42 is arranged on a fixed Inside the side wall of the groove 3, the hydraulic bladder 41 is communicated with the conduit assembly 42, and both the hydraulic bladder 41 and the conduit assembly 42 are filled with magnetorheological fluid;

[0035] When working, the magnetorheological fluid will turn into a solid state under the action of an external magnetic field. For example, when the screw 1 enters the fixing groove 3 and pushes the permanent magnet 15 into the sliding groove 14, the magnetorheological fluid will It will be transformed into a solid state under the action of the permanent magnet 15, and then the magnetorheological fluid at this time will not be able to flow.

Abstract

The invention discloses a screw fastener. The screw fastener comprises a screw and a fixing shell, a fixing groove with an opening is formed in the fixing shell, a hydraulic mechanism is arranged at the end, away from the opening, of the fixing groove, the hydraulic mechanism is in transmission connection with a plurality of limiting mechanisms capable of limiting the screw, the hydraulic mechanism is connected with a pressure regulating mechanism for controlling the hydraulic pressure in the hydraulic mechanism, and the pressure regulating mechanism is arranged in the inner wall of the fixing shell. Two threads with opposite textures are arranged on the screw, so that after the screw is limited by limiting plates, when torsional force is applied to the screw, the screw can bear two strands of force along the axis of the screw and in opposite directions through a first screw rod and a second screw rod, and the screw is prevented from moving in the fixing groove.

Description

technical field [0001] The invention relates to the technical field of hardware products, in particular to a screw fastener. Background technique [0002] Fasteners are the general term for a type of mechanical parts used to fasten two or more parts (or components) to form a whole, and screws are one of the most widely used fasteners. [0003] However, during the current screw fastening process, the screw fastening part is usually loosened, especially when the screw is frequently subjected to external and constantly changing external forces, which will make the connection of the screw fastening part not stable enough. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the screw connection is easy to loosen in the prior art, and propose a screw fastener. [0005] In order to achieve the above object, the present invention adopts the following technical solutions: [0006] A screw fastener, including a screw and a fixed hou...
