the utility model provides a locknut, includes the fastening lid, first through-hole has been seted up on the top of fastening lid, peg graft in the inside of first through-hole has the fastener, the bottom fixedly connected with plugboard of fastener, the bottom four corners of fastening lid is fixedly connected with location plug-in components respectively, the bottom lug joint of location plug-in components is in the inside of locating slot, just locating slot sets up in fixation nut's lateral wall, through pegging graft the fastening lid together with fixation nut through the fastener and fix to restrict the activity space of screw, and then prevent that the screw from producing when vibrations from becoming flexible and peg graft in fixation nut's lateral wall through the location plug-in components and prevent because the possibility that the fastening lid dropped, further tighten the fastening lid and fixation nut's joint mode.
Further, a clamping groove is formed in the inner wall of the fastening cover in the first through hole, and the clamping piece is clamped through the clamping groove.
Further, the side wall fixedly connected with joint spare of plugboard, just joint spare agrees with the joint groove mutually, cooperates joint spare with the joint groove through joint spare and joint groove and will fasten lid and fixation nut fixed.
Further, a second through hole is formed in the top end of the fixing nut, and the plug board is inserted through the second through hole.
Further, the plug board is inserted into the second through hole, and the fastening cover and the fixing nut are fixed relatively and cannot rotate freely through the plug board.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the fastening cover and the fixing nut are fixed together through the insertion connection of the fastening cover and the fixing nut, so that the movable space of the screw is limited, the screw is prevented from loosening during vibration, the possibility that the fastening cover falls off due to vibration is prevented through the insertion connection of the positioning plug-in unit to the side wall of the fixing nut, and the clamping connection mode of the fastening cover and the fixing nut is further tightened, so that the problems are solved.
