The specific technical scheme is as follows: the utility model provides an anti-skidding nut, includes insertion portion and screw thread portion, and screw thread portion has the screw, and screw thread portion is located the insertion portion top, and the insertion portion outer wall has anti-skidding surface, and the inside of insertion portion is equipped with the mating hole, screw thread portion includes toper portion, and the diameter of toper portion is dwindled to the tip by the main aspects, the diameter of main aspects is greater than the internal diameter of mating hole, and toper portion is connected through connecting portion with the insertion portion upper end, and when the top of toper portion was pressurized, connecting portion fracture, toper portion inserted in the mating hole, the insertion portion expands to the outside.
Preferably, the non-slip surface comprises grooves and protrusions, the protrusions being disposed between adjacent grooves.
Preferably, the convex part is an arc-shaped bulge.
Preferably, the outer wall of the threaded portion is provided with a locking hole, and a positioning piece is arranged in the locking hole.
Preferably, the positioning piece comprises a screw and an end head, the screw is in threaded connection with the locking hole, and the end head faces the direction of the screw hole.
Preferably, the locking holes are multiple and are arranged at intervals.
Preferably, an acute included angle is formed between the locking hole and the central axis of the screw hole.
The technical effects of the utility model: the utility model discloses an antiskid nut can make things convenient for the nut embedding installation, can make the portion of inserting and part combine closely simultaneously, strengthens anti-skidding performance.

Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 5, an anti-slip nut of the present embodiment includes an insertion portion 1 and a threaded portion 2, the threaded portion 2 having a threaded hole 20, the threaded portion 2 being located above the insertion portion 1. The outer wall of the insertion part 1 has a non-slip surface 11 and the inside of the insertion part 1 is provided with a mating hole 12. The threaded portion 2 includes a tapered portion 21, the tapered portion 21 having a diameter gradually decreasing from a large end 211 to a small end 212, the large end 211 having a diameter larger than an inner diameter of the mating hole 12. The tapered portion 21 is connected to the upper end of the insertion portion 1 through the connection portion 3, the connection portion 3 is broken when the top of the tapered portion 21 is pressed, the tapered portion 21 is inserted into the mating hole 12, and the insertion portion 1 is expanded outward. In the above technical solution, when a nut needs to be embedded in the component 10, the insertion portion 1 is placed in the mounting hole of the component 10, then the tool presses the upper end face of the insertion portion 1, the connection portion 3 is broken after the force is applied, and the threaded portion 2 enters the mating hole 12. The insert part 1 with a certain deformability is expanded outwards by the conical part 21, so that its non-slip surface 11 presses the component 10. Through the technical scheme, the nut can be conveniently installed, meanwhile, the insertion part 1 can be tightly combined with the part 10, and the anti-skid performance is enhanced.
In this embodiment, the anti-slip surface 11 comprises grooves 111 and protrusions 112, and the protrusions 112 are disposed between adjacent grooves 111, so that the anti-slip surface has an anti-slip function. The convex portion 112 is an arc-shaped protrusion.
In this embodiment, the outer wall of screw thread portion 2 is equipped with locking hole 3, is equipped with setting element 4 in the locking hole 3, setting element 4 is used for locking screw 5 to avoid the screw to deviate from. The positioning piece 4 comprises a screw rod 41 and an end 42, the screw rod 41 is in threaded connection with the locking hole 3, the end 42 faces the direction of the screw hole, so that the screw 5 is prevented from being disengaged by clamping the end 42 with the screw 5, and the end 42 can be made of a metal material to enhance the hardness of the end 42. The locking hole 3 has a plurality ofly, and a plurality of locking hole 3 intervals set up to can follow different direction locking screw 5, further strengthen the steadiness. An acute included angle a is formed between the locking hole 3 and the central axis of the screw hole 20.
The anti-skid nut of the embodiment can facilitate the installation of the nut, and meanwhile, the insertion part and the part can be tightly combined, so that the anti-skid performance is enhanced.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
