The utility model provides a not enough to prior art, the utility model provides a bolt that shock resistance is good possesses the advantage such as prevent not hard up, has solved the not hard up condition of nut easily to appear in the use of the bolt of plainness and tradition for the not hard up skew condition appears in the ware thing, is unfavorable for the fixed problem of stable erection of ware thing.

In order to achieve the above object, the utility model provides a following technical scheme: the bolt with good impact resistance comprises a first bolt head, a first screw is fixedly connected to the top of the first bolt head, a nut is fixedly connected to the outer side of the first screw, and a locking mechanism is arranged inside the first bolt head.

Locking mechanism includes and is four bolt with the inside sliding connection of first screw rod and quantity, the inside threaded connection of first screw rod has first clamping screw, the first fixing bolt head of first clamping screw's top fixedly connected with, four one side that the bolt is relative all is provided with the sphere, four one side that backs on the back of the body of bolt all is provided with the inclined plane.

Furthermore, the internal thread of the nut is connected with two fixing screws.

Furthermore, a through hole matched with the four bolts in size is formed in the first screw rod.

Furthermore, a circular groove is formed in the top of the first bolt head, and the bottom of the first fixing screw rod is conical.

Further, the bottom surface of the first screw is provided with a forty-five degree chamfer, and the outer surface of the first screw is provided with threads.

Furthermore, a thread groove matched with the first fixing screw in size is formed in the first screw.

Compared with the prior art, the technical scheme of the application has the following beneficial effects:

this bolt that shock resistance is good through setting up locking mechanism for under the effect of first clamping screw and four bolts, can prevent that first bolt head and first screw rod from taking place to become flexible, four bolts can be fine fix first screw rod on the object, through two set screw, can prevent not hard up of nut, thereby more firm to the object is fixed.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a top view of the present invention.

In the figure: the fixing structure comprises a spherical surface 1, a first fixing screw rod 2, a first fixing bolt head 3, a circular groove 4, a first bolt head 5, a bolt pin 6, a first screw rod 7, a nut 8 and a fixing screw 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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, in the embodiment, the bolt with good impact resistance includes a first bolt head 5, a circular groove 4 is formed at the top of the first bolt head 5, a first screw 7 is fixedly connected to the top of the first bolt head 5, a thread is formed on the outer surface of the first screw 7, a bottom surface of the first screw 7 is a forty-five degree chamfer, a through hole matched with the size of four bolts 6 is formed inside the first screw 7, a nut 8 is fixedly connected to the outer side of the first screw 7, two fixing screws 9 are connected to the inner thread of the nut 8, and a locking mechanism is arranged inside the first bolt head 5

Locking mechanism includes and is four bolt 6 with 7 inside sliding connection of first screw rod and quantity, the inside threaded connection of first screw rod 7 has first clamping screw 2, the threaded groove with 2 size looks adaptations of first clamping screw is seted up to the inside of first screw rod 7, the bottom of first clamping screw 2 is the tapered, the first clamping screw head 3 of top fixedly connected with of first clamping screw 2, four 6 relative one sides of bolt all are provided with sphere 1, four 6 one side of carrying on the back of the body of bolt all are provided with the inclined plane.

The first screw 7 and the first bolt head 5 are both low-carbon alloy steel or medium-carbon steel, the impact resistance of the low-carbon alloy steel or medium-carbon steel can be greatly increased after heat treatment, and the four bolts 6 are all magnetic.

It should be noted that under the action of the first fixing screw 2 and the four bolts 6, the first bolt head 5 and the first screw 7 can be prevented from loosening, the four bolts 6 can fix the first screw 7 on an object well, and the two fixing screws 9 can prevent the nut 8 from loosening, so that the object is fixed more firmly.

The working principle of the above embodiment is as follows:

this bolt that shock resistance is good, screw into the object through first bolt head 5 with first screw rod 7, rethread first fixing bolt head 3 enters into first screw rod 7 with first fixing screw rod 2 through the screw thread recess is rotatory, extrude first screw rod 7 with four bolts 6 through first fixing screw rod 2, inject the object through the inclined plane of the one side that bolt 6 carried on the back mutually, thereby fix first screw rod 7, through two set screw 9, can fix nut 8, thereby prevent that nut 8 is not hard up.
