Abstract

The utility model provides a high-strength bolt which comprises a bolt head and a screw rod arranged below the bolt head, wherein the bolt head is round and flat, a first reinforcing ring and a second reinforcing ring which are different in diameter and are round are arranged on the upper surface of the bolt head, and the circle centers of the first reinforcing ring and the second reinforcing ring are overlapped with the circle center of the bolt head. According to the high-strength bolt provided by the utility model, the two raised first reinforcing rings and the two raised second reinforcing rings are arranged on the upper surface of the bolt head, and the strength of the bolt head is improved through the two reinforcing rings, so that the bolt head is not easy to bend and break.

Description

High-strength bolt

Technical Field

The utility model belongs to the technical field of bolts, and particularly relates to a high-strength bolt.

Background

A bolt is a mechanical part, with a cylindrical threaded fastener of a nut. A fastener consisting of a head part and a screw rod (a cylinder with external threads) needs to be matched with a nut for fastening two parts with through holes. This form of connection is called bolting. If the nut is screwed off the bolt, the two parts can be separated, so the bolt connection belongs to the detachable connection.

The existing flat bolt head bolt is thinner in bolt head, lower in strength and easy to break.

Disclosure of Invention

The main object of the present utility model is to provide a high strength bolt which improves the strength of the bolt head so as not to be easily broken.

In order to achieve the above purpose, the utility model provides a high-strength bolt, which comprises a bolt head and a screw rod arranged below the bolt head, wherein the bolt head is round and flat, a first reinforcing ring and a second reinforcing ring which are round and have different diameters are arranged on the upper surface of the bolt head, and the circle centers of the first reinforcing ring and the second reinforcing ring are overlapped with the circle center of the bolt head.

According to the high-strength bolt provided by the utility model, the two raised first reinforcing rings and the two raised second reinforcing rings are arranged on the upper surface of the bolt head, and the strength of the bolt head is improved through the two reinforcing rings, so that the bolt head is not easy to bend and break.

In one possible implementation, a third reinforcing ring is arranged on the lower surface of the bolt head, and the center of the third reinforcing ring coincides with the center of the bolt head. The third reinforcing ring is arranged on the lower surface of the bolt head, and the strength of the surface of the bolt head is further improved by arranging the third reinforcing ring on the lower surface.

In one possible implementation, the diameter of the third reinforcement ring is greater than the diameter of the first reinforcement ring and less than the diameter of the second reinforcement ring. The position of the third reinforcing ring is staggered with the first reinforcing ring and the second reinforcing ring, so that the bending strength of the bolt head can be further improved.

In one possible implementation, the top of the screw is provided with a conical reinforcing structure, and the surface of the conical reinforcing structure is provided with reinforcing ribs. The conical reinforcing structure improves the connection strength between the bolt head and the screw.

In one possible implementation, a straight slot is provided on the upper surface of the bolt head. A straight slot is provided for turning the high strength bolt.

Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the utility model defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

In the description of the present application, it should be understood that the azimuth or positional relationship indicated by the terms "upper", "lower", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of description of the present application and to simplify the description, and do not indicate or imply that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the present application.

In the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

Referring to fig. 1 and 2 of the drawings, the utility model provides a high-strength bolt, which comprises a bolt head 1 and a screw rod 2 arranged below the bolt head 1, wherein the bolt head 1 is in a round flat shape, a first reinforcing ring 31 and a second reinforcing ring 32 which are different in diameter and are round are arranged on the upper surface of the bolt head 1, and the circle centers of the first reinforcing ring 31 and the second reinforcing ring 32 are coincident with the circle center of the bolt head 1.

According to the high-strength bolt provided by the utility model, the two raised first reinforcing rings 31 and the two raised second reinforcing rings 32 are arranged on the upper surface of the bolt head 1, and the strength of the bolt head 1 is improved through the two reinforcing rings, so that the bolt head 1 is not easy to bend and break.

In one possible implementation, a third reinforcing ring 33 is provided on the lower surface of the bolt head 1, and the center of the third reinforcing ring 33 coincides with the center of the bolt head 1. The third reinforcing ring 33 is provided on the lower surface of the bolt head 1, and the third reinforcing ring 33 is provided on the lower surface, further improving the strength of the surface of the bolt head 1.

In one possible implementation, the diameter of the third reinforcement ring 33 is greater than the diameter of the first reinforcement ring 31 and smaller than the diameter of the second reinforcement ring 32. The position of the third reinforcing ring 33 is offset from the first reinforcing ring 31 and the second reinforcing ring 32, so that the bending strength of the bolt head 1 can be further improved.

In one possible implementation, the top of the screw 2 is provided with a conical reinforcing structure 4, and the surface of the conical reinforcing structure 4 is provided with reinforcing ribs 5. The provision of the conical reinforcing structure 4 improves the strength of the connection between the bolt head 1 and the screw 2.

In one possible implementation, the bolt head 1 is provided with a slot 6 in the upper surface. A slot 6 is provided for turning the high strength bolt.

It should be noted that, for those skilled in the art, modifications may still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions may be made on some of the technical features thereof, and any modifications, equivalent substitutions, improvements, etc. should be included in the protection scope of the present utility model within the spirit and principle of the present utility model.
