CN220365850U - Locking stud - Google Patents

Abstract

The utility model provides a locking stud which comprises a stud head, a first screw rod arranged on the upper surface of the stud head, and a second screw rod arranged on the lower surface of the stud head, wherein round locking grains are further arranged on the upper surface and the lower surface of the stud head. The anti-loosening stud provided by the utility model is characterized in that anti-loosening threads are arranged on the upper surface of the stud head of the stud. After the stud is installed, the anti-loosening patterns on the upper surface and the lower surface of the stud head are in contact with the surfaces of the parts, so that the friction resistance is increased, the resistance when the stud is accidentally rotated is reduced, and the possibility of loosening the stud is reduced.

Description

Locking stud

Technical Field

The utility model belongs to the technical field of stud bolts, and particularly relates to a locking stud bolt.

Background

The stud is a bolt with two threaded rods. Such bolts are commonly used to connect components that require frequent disassembly or adjustment, such as machines, equipment, or structural members. The two screws of the stud bolts can be connected with each other to achieve the purpose of fastening and unfastening. The stud is usually made of a long rod with screws at each end. This design allows the stud to be rotated from both ends to screw it in or out. The two screws of the stud may have different diameters, pitches and thread types to accommodate different application scenarios. The stud is usually used in combination with a nut for tightening and loosening purposes. When using a stud bolt, it is necessary to ensure that the gap between the screw and the nut is large enough so that the nut can be easily adjusted and tightened.

The bolt head of the existing double-headed screw is not provided with a structure for preventing the bolt from loosening, and the phenomenon of loosening the bolt is easy to occur after the installation, so that the installation structure is unstable.

Disclosure of Invention

The utility model mainly aims to provide a locking stud, and a locking structure is added on a stud head, so that the locking performance of the stud is improved, and the stability after installation is improved.

In order to achieve the above purpose, the utility model provides a locking stud bolt, which comprises a bolt head, a first screw rod arranged on the upper surface of the bolt head, and a second screw rod arranged on the lower surface of the bolt head, wherein round locking grains are further arranged on the upper surface and the lower surface of the bolt head.

The anti-loosening stud provided by the utility model is characterized in that anti-loosening threads are arranged on the upper surface of the stud head of the stud. After the stud is installed, the anti-loosening patterns on the upper surface and the lower surface of the stud head are in contact with the surfaces of the parts, so that the friction resistance is increased, the resistance when the stud is accidentally rotated is reduced, and the possibility of loosening the stud is reduced.

In one possible implementation, the anti-loosening pattern is provided with three turns on the upper and lower surfaces of the bolt head. The anti-loosening performance of the threads is further improved by arranging a plurality of rings of anti-loosening threads.

In one possible implementation, the bolt head is regular hexagonal.

In one possible implementation, the three sides of the bolt head are provided as cambered surfaces, which are concave inwards. Three cambered surfaces are arranged, so that the material consumption is saved.

In one possible implementation manner, the side surface of the bolt head is in a structure of staggered cambered surface and plane.

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 of the drawings, fig. 1 is a schematic structural view of a locking stud provided by the present utility model, and as shown in fig. 1, the locking stud provided by the present utility model includes a bolt head 1, a first screw 21 disposed on an upper surface of the bolt head 1, and a second screw 22 disposed on a lower surface of the bolt head 1, wherein circular locking grooves 3 are further disposed on the upper and lower surfaces of the bolt head 1.

The anti-loosening stud provided by the utility model is characterized in that anti-loosening threads 3 are arranged on the upper surface of a stud head 1 of the stud. After the stud is installed, the anti-loosening patterns 3 on the upper surface and the lower surface of the stud head 1 are in contact with the surfaces of the parts, so that the friction resistance is increased, the resistance when the stud is accidentally rotated is reduced, and the possibility of loosening the stud is reduced.

In one possible implementation, the anti-loosening pattern 3 is provided with three turns on the upper and lower surfaces of the bolt head 1. The multi-ring anti-loosening threads 3 are arranged, so that the anti-loosening performance of the threads is further improved.

In one possible implementation, the bolt head 1 is a regular hexagon.

In one possible implementation, three sides of the bolt head 1 are provided as cambered surfaces 4, the cambered surfaces 4 being concave inwards. Three cambered surfaces 4 are arranged, so that the material consumption is saved.

In one possible implementation, the side surface of the bolt head 1 is a cambered surface 4 and a plane staggered arrangement structure.

It should be noted that technical features such as basic structural principles of the stud bolt related to the present application should be regarded as the prior art, and specific structures, working principles, and control modes and spatial arrangement modes possibly related to the technical features should be selected conventionally in the art, and should not be regarded as the point of the utility model of the present application, which is not further specifically described in detail.
