Bolt looseness early warning gasket

Abstract

The invention relates to the technical field of sealing gaskets, and discloses a bolt looseness early warning gasket. The gasket comprises a gasket body and a warning piece, wherein a material storage chamber is arranged in the gasket body, the material storage chamber is filled with a mechanochromic material, the warning piece comprises a transparent material guide pipe, the material guide pipe communicates with the material storage chamber, the volume of the material guide pipe is smaller than that of the material storage chamber, after the gasket body is pressed, the mechanochromic in the material storage chamber enters the material guide pipe, due to the fact that the volume of the material guide pipe is smaller than that of the material storage chamber, the pressure borne by the mechanochromic material is increased, the color of the mechanochromic material is changed, and people can see the color through the transparent material guide pipe; and when a bolt is loosened, the mechanochromic material flows back into the material storage chamber, and the pressure applied to the mechanochromic material by the material guide pipe is further reduced, so that the color of the mechanochromic material is changed or disappears, it is indicated that the bolt is loosened, the material storage chamber can be pre-filled with the mechanochromic material, installation and operation are convenient, and the labor amount of constructors is reduced.

Description

technical field [0001] The invention relates to the technical field of sealing gaskets, in particular to a bolt loosening warning gasket. Background technique [0002] Due to the advantages of simple structure and convenient disassembly and assembly, bolt connection is widely used in the connection of power equipment, especially for the connection of tower materials for transmission line towers. The reliability of the connection is closely related to the safety and stability of transmission towers. Therefore, bolts A secure and reliable connection is very important. [0003] Under the action of external loads such as wind load, icing, vibration, etc., especially with the vibration or even galloping of the wires, the transmission tower needs to bear various dynamic loads, and the axial force on the angle steel of the tower body changes alternately, which may easily cause the bolt connection of the tower nodes. The loosening or even falling off will seriously affect the stabi...
