The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a locking bolt that moves of high strength, includes the bolt, the bolt include the double-screw bolt and with double-screw bolt fixed connection's nut, be provided with screw thread district and spacing district on the double-screw bolt, spacing district is located screw thread district upper portion, be provided with the screw thread in the screw thread district of double-screw bolt, be provided with the multiunit recess in the spacing district of double-screw bolt, every group the top of recess is all rotated and is connected with the stopper, the inside bullet piece that is provided with of recess, bullet piece one end with stopper fixed connection, bullet piece other end with recess inner wall fixed connection, just the stopper protrusion the recess.

The limiting block can be completely embedded into the groove.

The equal fixedly connected with axle piece in top both sides of stopper, recess top both sides all are provided with the shaft hole, the axle piece rotates to be connected in the shaft hole.

The bolt is provided with a plurality of groups of nuts and gaskets in a matched mode.

The elastic piece is of a U-shaped structure.

The grooves are in 3-4 groups.

When the nut is in threaded connection with the stud, the bottom end of the limiting block is in contact with the top surface of the nut.

The utility model has the advantages that: this device simple structure is novel, can pop out the stopper from the recess through playing the piece, during nut and bolted connection, the nut cover is on the double-screw bolt, push down each group spacing piece through the nut and make stopper gomphosis to the recess in, can move down the nut to the threaded area and carry out threaded connection, nut threaded connection back, each group spacing piece pops out the recess with it because of the elasticity of playing the piece, and with the top surface contact of nut, carry on spacingly through the stopper to the nut, thereby reducible nut is not hard up, guarantee that nut and bolted connection are firm.

In the figure: 1 double-screw bolt, 2 nut, 3 screw thread district, 4 spacing districts, 5 recesses, 6 stopper, 7 bullet spare, 8 axle pieces, 9 shaft holes, 10 nuts, 11 gaskets.

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.

Please refer to fig. 1-3, a high-strength anti-loosening bolt, which comprises a bolt, the bolt comprises a stud 1 and a nut 2 fixedly connected with the stud 1, a threaded area 3 and a limiting area 4 are arranged on the stud 1, the limiting area 4 is located on the upper portion of the threaded area 3, threads are arranged on the threaded area 3 of the stud 1, 3-4 groups of grooves 5 are arranged on the limiting area 4 of the stud 1, the top of each group of grooves 5 is rotatably connected with a limiting block 6, an elastic piece 7 is arranged inside the groove 5, the elastic piece 7 is of a U-shaped structure, one end of the elastic piece 7 is fixedly connected with the limiting block 6, the other end of the elastic piece 7 is fixedly connected with the inner wall of the groove 5, the limiting block 6 protrudes out of the groove 5, and when the limiting block 6 is pressed down, the elastic piece 7 can be compressed to enable the limiting block 6 to be completely embedded into the groove 5, so that the nut 10 can penetrate into the groove.

This device says more specifically, the equal fixedly connected with axle piece 8 in stopper 6's the top both sides, and 5 top both sides of recess all are provided with shaft hole 9, and axle piece 8 rotates to be connected in shaft hole 9 to this rotation that realizes between stopper 6 and the recess 5 is connected.

When nut 10 threaded connection is on double-

screw bolt

1, 6 bottom of stopper and the contact of nut 10 top surface to carry on spacingly through stopper 6 to nut 10, thereby guarantee that the bolt is firm with being connected of nut 10, simultaneously for guaranteeing that nut 10 can contact with stopper 6, what this device matches is provided with multiunit nut 10 and gasket 11, lifts the nut 10 on top through multiunit nut 10 and gasket 11, in order to realize the effect of stopper 6 and the contact of nut 10 top surface.
