The utility model provides a locking bolt, which aims to solve the problem that the existing bolt is easy to loose due to vibration of machinery or parts in the long-term use process.
The anti-loosening bolt comprises a screw rod and a bolt head arranged at one end of the screw rod, and is characterized in that an auxiliary screw rod movably connected with the screw rod is arranged at the other end of the screw rod, the screw pitch of the auxiliary screw rod is smaller than that of the screw rod, the screw thread direction of the auxiliary screw rod is opposite to that of the screw rod, and when looseness occurs between the screw rod and a screw hole or a nut, the auxiliary screw rod or the nut on the auxiliary screw rod can effectively prevent the screw rod from continuing to loosen, so that the anti-loosening and anti-dismantling effects are achieved.
The screw rod is set to long screw rod, its length, diameter are established to multiple according to the connection needs, and the bolt head is located the screw rod rear end, is equipped with the short lead screw of connection pair screw rod on the terminal surface of screw rod front end, and short lead screw diameter is less than the screw rod diameter to screw thread direction is opposite with the screw rod screw thread direction, and the bolt head is established to polygonal bolt head or is established to the bolt head of establishing spanner jack on it, prevents through the short lead screw that screw thread and screw rod set up in opposite direction that screw rod is gone up screw-up that the screw rod is not hard up with the screw rod appearance.
The auxiliary screw rod is designed into a short screw rod, the lengths of the auxiliary screw rod are multiple according to the needs, the diameters of the auxiliary screw rod are consistent with the diameters of the screw rods, screw holes matched with the short screw rod are formed in the end face of the inner end of the auxiliary screw rod, wrench insertion holes are formed in the end face of the outer end of the auxiliary screw rod, so that the movable connection between the auxiliary screw rod and the screw rod is realized in a threaded connection mode, after the screw rod is screwed into a needed connection position, the auxiliary screw rod is screwed onto the short screw rod of the screw rod, and when looseness is generated between the screw rod and the screw hole or the screw nut, the auxiliary screw rod or the screw nut on the auxiliary screw rod can effectively prevent the screw rod from continuing to loosen, so that the effects of loosening prevention and disassembly prevention are achieved.
The utility model has the following advantages and effects that by adopting the scheme, the auxiliary screw rod with the opposite screw thread direction is additionally arranged at the tail part of the traditional bolt to play a role of locking the bolt or the nut on the bolt, thereby preventing the bolt or the nut from loosening due to vibration and the like. Meanwhile, the simple structure brings convenience to processing, and the manufacturing cost is effectively reduced.
