Problems solved by technology

[0003] Most of the existing fasteners have the problem of loosening of the fasteners. The fasteners begin to loosen. After the threaded fasteners are loosened, huge kinetic energy is generated. The firmware is damaged. After the fastener is damaged, the device cannot operate normally, which will further lead to damage to the device and cause economic losses

Abstract

The invention discloses an anti-loosening mechanical fastener. The anti-loosening mechanical fastener comprises a screw and a nut, wherein the screw comprises a screw cap and a screw rod; the screw rod is fixedly arranged at the bottom of the screw cap, and a cross-shaped groove is fixedly formed in the top of the screw cap; a thread is fixedly arranged on the axial surface of the screw rod, and aclamping device is fixedly arranged on the axial surface of the screw cap; the nut is fixedly arranged at the bottom of the screw; a clamp holder is fixedly arranged on the axial surface of the nut and comprises an arc-shaped clamping sleeve, a clamping plate and an adjusting rod; and the clamping plate is fixedly arranged on the axial surface of the arc-shaped clamping sleeve, and the adjustingrod is fixedly arranged in the clamping plate. The anti-loosening mechanical fastener is novel in structure and high in practicability. The clamping device is fixedly arranged on the screw cap, so that clamping force is provided for the nut and the screw in the longitudinal direction, and the screw and the nut do not loosen in the longitudinal direction after being mounting. The clamp holder is arranged on the axial surface of the nut, so that external clamping force is provided for the nut, and the nut is ensured to be fastened on the screw and is prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a mechanical fastener for preventing loosening. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments All kinds of fasteners can be seen on the , chemical industry, instruments and supplies, etc., which are the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people also refer to a class of fasteners with existing national standards as standard fasteners, or simp...
