Description
Technical Field
The utility model relates to a bolt and nut connects technical field, especially relates to an anti-loosening and anti-dropping bolt and nut assembly.
Background
Bolt: mechanical parts, a cylindrical threaded fastener matched with a nut, a fastener composed of a head and a screw (a cylinder with an external thread), and the like, need to be matched with the nut and are used for fastening and connecting two parts with through holes; bolt-nut assemblies are widely used in daily life, and are mainly used for mounting and fastening various components, the existing bolt-nut assemblies are composed of bolts with external threads and nuts with internal threads, and are easy to mount and dismount, but the bolts are easy to loosen after a long time or external vibration is applied to the bolts, so that safety accidents are easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the bolt and nut are easy to loose in the prior art and providing a locking and anti-dropping bolt and nut assembly.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the anti-loosening and anti-dropping bolt and nut assembly comprises a bolt, wherein a first flange sheet is fixedly welded at the top of the bolt, a threaded rod is fixedly installed at the central position of the top of the first flange sheet, a flange nut is arranged above the bolt and sleeved outside the threaded rod and in threaded connection with the threaded rod, a second flange sheet is fixedly installed at the bottom of the flange nut and in threaded connection with the threaded rod, a nut is installed above the flange nut, the nut is sleeved outside the threaded rod and in threaded connection with the threaded rod, a threaded groove is formed in the top of the threaded rod, a screw is in threaded connection with the inside of the threaded groove, a fixed block is fixedly installed on the threaded groove, compression springs are fixedly installed on two sides of the fixed block, and abutting blocks are fixedly connected with the outer ends of the two compression springs, the contact block penetrates through the inner wall of the thread groove and is in sliding connection with the threaded rod.
Preferably, the inner wall of the thread groove is provided with a through sliding groove matched with the abutting block.
Preferably, the outer side wall of the contact block is of a cambered surface structure.
Preferably, the bottom of the second flange plate is fixedly provided with a threaded ring, and the outer side wall of the threaded ring is of a threaded structure.
Preferably, a clamping groove matched with the threaded ring is formed in the top surface of the first flange piece, and the threaded ring is in threaded connection with the clamping groove.
The utility model provides a pair of locking anticreep bolt and nut subassembly, beneficial effect lies in: after the bolt is connected with the nut, the conflict piece outwards stretches out under compression spring's effect, acts on the inner wall of nut this moment, because the inside of nut is helicitic texture, the conflict piece can be inconsistent with the inner wall of nut, avoids the nut to take place not hard up, in addition, makes the fixed block more stable through changeing tight threaded rod, and compression spring has certain antidetonation effect simultaneously.
