The utility model mainly aims to provide an anti-loosening bolt and nut assembly which can effectively solve the problems in the background technology.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the anti-loosening bolt and nut assembly comprises a bolt main body, nuts and stop blocks, wherein the nuts are sleeved on the surface threads of the bolt main body, and the stop blocks are movably embedded on the surfaces of two sides of the bolt main body.
Preferably, the two side surfaces of the bolt main body are provided with storage grooves, the two side surfaces of the inner part of each storage groove are provided with moving grooves, guide rods are fixedly arranged in the moving grooves, and springs are sleeved on the surfaces of the guide rods.
Preferably, sleeve blocks are fixedly arranged on the surfaces of two sides of the rear end of the stop block, and the stop block is movably embedded in the storage groove.
Preferably, the number of the accommodating grooves is three, and the three accommodating grooves are longitudinally and uniformly distributed on the two side surfaces of the bolt body.
Preferably, the sleeve block is sleeved on the surface of the guide rod, and the stop block is movably connected with the bolt main body through the sleeve block.
Preferably, one end of the spring is connected with the sleeve block, and the other end of the spring is connected with the surface of one end inside the movable groove.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, by arranging the bolt main body and the stop block to be matched with each other, when the bolt main body is inserted into the fixing hole, the stop block is extruded into the accommodating groove of the bolt main body, so that the bolt main body can smoothly pass through the fixing hole, then the nut is sleeved on the surface of the bolt main body, in the process of rotating and rising the nut, the stop block is extruded into the accommodating groove again, when the nut moves to the upper part of the stop block, the stop block extends out of the accommodating groove of the bolt main body under the pushing action of the spring, the stop block extending out of the accommodating groove can stop the rotation and the falling of the nut after being installed, and thus even if the bolt main body is vibrated, the nut cannot rotate and fall due to vibration.
