Description

Pressure release bolt that can anticreep Technical Field The utility model belongs to the technical field of pressure relief bolts, and particularly relates to a pressure relief bolt capable of preventing falling. Background The bolt is a connecting part, can play a dead fixed effect of locking two objects through screw hole and thread groove, and the bolt comprises head and screw rod (the cylinder that has the external screw thread) two parts, and the bolt history is long, uses extensively in industrial manufacturing, and the inside gas of the container that the part was equipped with gas often needs to carry out the pressure release to its inside because of atmospheric pressure is higher, need use the locking bolt that can release. The locking bolt that can release among the prior art, in the use, mostly seal pressure release passageway at locking bolt inside fixed mounting spring and sealing block, the spring uses elasticity to descend easily for a long time, just so influences sealed effect, and the sealing block also takes place ageing easily simultaneously. Therefore, a pressure relief bolt capable of preventing falling is needed, and the problems that springs and sealing blocks inside the pressure relief bolt are easy to age and are not easy to replace in the prior art are solved. Disclosure of utility model The utility model aims to provide a release-proof pressure relief bolt so as to solve the problems in the background technology. In order to achieve the purpose, the utility model provides the following technical scheme that the anti-drop pressure relief bolt comprises a pressure relief bolt body and further comprises: The pressure relief cylinder is fixed at the end part of the pressure relief bolt body, a connecting hole is formed in the pressure relief bolt body, a cylindrical cavity is formed in the pressure relief cylinder, and a plurality of pressure relief holes are uniformly formed in the inner wall of the pressure relief cylinder; The movable disc is arranged in the cylindrical cavity in a sliding mode, a sealing block matched with the connecting hole is fixed on the bottom surface of the movable disc, a movable rod is fixed on the top surface of the movable disc, an annular clamping groove is formed in the inner wall of the cylindrical cavity, a chuck is arranged on the inner wall of the annular clamping groove, a limiting assembly matched with the chuck is arranged in the pressure release cylinder, the movable rod penetrates through the chuck in a movable mode, a second spring is sleeved on the outer surface of the movable rod, and the second spring is located between the movable disc and the chuck. In the scheme, it is to be noted that the limiting assembly includes: The movable hole is provided with two and is the symmetry and offer in the inside of pressure release section of thick bamboo, the inside swing joint in movable hole has the gag lever post, the surface fixed cover of gag lever post is equipped with the connecting block, the surface cover of gag lever post is equipped with first spring, the one end and the fixed surface of connecting block of first spring, the other end and the inner wall in movable hole of first spring are fixed, two spacing holes that are symmetric distribution have been offered to the surface of chuck, the tip and the spacing hole grafting of gag lever post. It is further worth to say that annular groove has been seted up to the surface of pressure release section of thick bamboo, the inside fixed mounting of annular groove has the slipmat, a plurality of anti-skidding grooves have evenly been seted up to the surface of slipmat.
