In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a novel cap nut, includes nut body and the block that integrative was made, the coaxial fixed connection of the horizontal other end of nut body prevents the loose piece, the inner wall fixedly connected with locking mechanism of block.
Preferably, the outer wall of the anti-loosening block is provided with a plurality of annular grooves, and the cross sections of the plurality of annular grooves are similar to V-shaped.
Preferably, the outer wall of the anti-loosening block is provided with a plurality of annular grooves, and the cross sections of the plurality of annular grooves are square.
Preferably, the bottom of the annular groove is coaxially and fixedly connected with an annular antiskid plate, and the bottom of the annular antiskid plate is provided with an antiskid lug.
Preferably, the inner wall of the cap is provided with air holes, and the air holes penetrate through the nut body, the anti-loosening block annular anti-slip plate and the anti-slip lugs.
Preferably, locking mechanism includes the spacing groove, spacing groove fixed connection is at the inner wall of block, the spacing inslot portion is equipped with the spring, spring one end is fixed on the spacing groove, and the other end can be dismantled with the gag lever post and be connected, fixed connection elastic connecting rod on the gag lever post, elastic connecting rod one end runs through the spacing groove and extends to outside the spacing groove.
Compared with the prior art, the beneficial effects of the utility model are that: the nut is locked by the locking mechanism arranged on the inner wall of the cap and the annular anti-loosening block arranged below the nut body to reduce loosening, and the friction force between the anti-loosening block and the workpiece is increased by the anti-loosening block arranged on the annular anti-loosening plate to further reinforce the workpiece.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a novel cap nut, includes nut body 1 and block 2 that integrative was made, the coaxial fixed connection of the horizontal other end of nut body 1 prevents loose piece 3, and the inner wall fixedly connected with locking mechanism 21 of block 2.
Be equipped with a plurality of annular grooves 31 on anti-loosening block 3's the outer wall, annular groove 31 cross-section is type "V" type, a plurality of annular grooves 31's cross-section is square, the coaxial fixedly connected with annular antiskid ribbed tile 32 in annular groove 31's bottom, annular antiskid ribbed tile 32 bottom is equipped with anti-skidding lug 33, the inner wall of block 2 is equipped with bleeder vent 22, bleeder vent 22 runs through nut body 1, locking block 3, annular antiskid ribbed tile 32 and anti-skidding lug 33, locking mechanism 21 includes spacing groove 211, spacing groove 211 fixed connection is at the inner wall of block 2, the inside spring 212 that is equipped with of spacing groove 211, spring 212 one end is fixed on spacing groove 211, the other end can be dismantled with gag lever post 213 and be connected, fixed connection elastic connecting rod 214 on the gag lever post 213, elastic connecting rod 214 one end runs through spacing groove 211 and extends to.
The utility model discloses a spacing groove 211 in the locking mechanism 21, spring 212, gag lever post 213, elastic connecting rod 214 produces decurrent effort to the bolt, annular groove 31 through on the anti-loosening block 3 produces deformation and produces ascending effort to the nut, these two power make the frictional force between nut and the bolt increase, frictional force through establishing anti-skidding lug 33 on annular antiskid ribbed tile 32 increases nut and work piece makes the nut paste more and the work piece, extrude the gas in the cap 2 through the bleeder vent 22 that is equipped with on the 2 inner walls of cap, the screw in nut that can relax more.
The utility model discloses principle and use flow: the cap-shaped nut is screwed in, the anti-slip groove is firstly contacted with a workpiece when the nut body 1 descends, the nut is continuously screwed in, the annular groove 31 on the anti-loose block is extruded to generate an upward reaction force to act on the nut body 1, then the nut is screwed in, the bolt is contacted with the elastic connecting rod 214 and extrudes the elastic connecting rod 214, the elastic railing 214 pushes the limiting rod 213 to move in the limiting groove 211, the limiting rod pushes the spring 212, the spring 212 is extruded and deformed to generate a reaction force to act on the limiting rod 213 and the elastic connecting rod 214, therefore, the bolt is subjected to a downward reaction force due to the upward reaction force on the nut body 1, the two opposite reaction forces increase the friction force between the bolt and the nut, the anti-loose effect is enhanced, the anti-slip lug 33 positioned at the bottom increases the friction force between the nut and the workpiece to, when the nut is screwed in, air remained in the cap is discharged through the air holes 22, so that the nut is screwed in more easily.
