Description

Technical Field

[0001] This utility model relates to the technical field of fastener installation, and more particularly to a high-strength bolt for industrial applications. Background Technology

[0002] Double-ended studs, also called double-ended bolts or double-ended threaded studs, are used for fixing and connecting mechanical parts. They have threads on both ends, with a central thread that can be either thick or thin. Due to their high strength, they are often used in the assembly and connection of components in large industrial equipment.

[0003] Inevitably, in practical work, the operation of mechanical equipment can easily generate vibrations or impacts. Under the action of external loads, the nuts of double-ended studs are prone to loosening. If this is repeated, the threaded connection will loosen or even fail. Therefore, how to prevent the nuts of double-ended studs from loosening and ensure their high-strength and effective connection of components is an urgent problem to be solved. Utility Model Content

[0004] In view of the above problems, this utility model provides a high-strength bolt for industrial applications, the purpose of which is to ensure the reliability of high-strength bolt connections.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-strength bolt for industrial applications is provided, comprising: a bolt body and a nut connected by threads; a limiting groove, parallel to the axial direction of the bolt body, formed on the bolt body; a mounting ring, coaxial with the bolt body, fixedly mounted on the nut; a limiting member, sleeved on the bolt body, located between the bolt body and the mounting ring; a limiting protrusion, provided on the limiting member, capable of being inserted into the limiting groove; and a press-fitting member, detachably provided on the mounting ring, for press-fitting the limiting member onto the nut.

[0006] Furthermore, the bolt also includes a countersunk hole formed on the nut for mounting the limiting component.

[0007] Furthermore, the bolt also includes: a flexible layer made of rubber, which is bonded to the bottom surface of the mounting hole; and an anti-slip protrusion located on one side of the limiting component, which can be embedded in the flexible layer.

[0008] Furthermore, the press-fit component includes a locking screw and a pressure block. One end of the pressure block is used to press against the limiting component, and the other side of the pressure block has a through hole. The locking screw passes through the through hole and is set inside the mounting ring. The nut of the locking screw presses the pressure block against the device.

[0009] Furthermore, four pressure blocks are arranged in a circular array along the circumferential direction of the screw body.

[0010] The beneficial effects of this utility model are as follows: In this utility model, by setting a press-fitting component, the limiting component can be fixedly press-fitted onto the nut; a limiting protrusion is provided on the limiting component, and the limiting protrusion can enter into the limiting groove, thereby preventing the bolt body and the nut from rotating relative to each other in the circumferential direction, preventing the bolt body and the nut from loosening, and ensuring the reliability of the high-strength connection and installation of the bolt to the components.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, this application discloses a high-strength bolt for industrial applications, comprising: a bolt body 11 and a nut 12 connected by threads; a limiting groove 111, parallel to the axial direction of the bolt body 11, formed on the bolt body 11; a mounting ring 2, coaxial with the bolt body 11, fixedly mounted on the nut 12; a limiting member 3, sleeved on the bolt body 11, located between the bolt body 11 and the mounting ring 2; a limiting protrusion 31, disposed on the limiting member 3, capable of being inserted into the limiting groove 111; and a pressing member, detachably disposed on the mounting ring 2, for pressing the limiting member 3 onto the nut 12.

[0018] In practical use, the bolt body 11 is passed through the component to be connected and installed, and two nuts 12 are tightened at both ends of the bolt body 11 by threaded connection; then the limiting component 3 is sleeved on the bolt body 11, ensuring that the limiting protrusion 31 is in the limiting groove 111, the limiting component 3 is slid along the axial direction of the bolt body 11, the limiting component 3 is placed between the mounting ring 2 and the bolt body 11, and finally the limiting component 3 is pressed and fixed on the nut 12 by the pressing component to complete the installation.

[0019] In this utility model, by setting a press-fitting component, the limiting component 3 can be fixedly press-fitted onto the nut 12; a limiting protrusion 31 is provided on the limiting component 3, and the limiting protrusion 31 can enter into the limiting groove 111, thereby preventing the bolt body 11 and the nut 12 from rotating relative to each other in the circumferential direction, preventing the bolt body 11 and the nut 12 from loosening, and ensuring the reliability of the high-strength connection and installation of the bolt as a whole to the components.

[0020] In this embodiment, the bolt body 11 is a double-ended bolt, and two nuts 12 are provided on the bolt body 11.

[0021] Specifically, the bolt also includes: a countersunk hole, which is formed on the nut 12 for the installation of the limiting component 3; the limiting component 3 is embedded in the countersunk hole to achieve the purpose of positioning the limiting component 3.

[0022] Preferably, the bolt further includes: a flexible layer 121 made of rubber, which is bonded to the bottom surface of the mounting hole; and an anti-slip protrusion 32, which is disposed on one side of the limiting member 3 and can be embedded in the flexible layer 121.

[0023] The pressing component presses the limiting component 3 onto the nut 12. Simultaneously, it can also embed the anti-slip protrusion 32 into the flexible layer 121 to increase the friction between the limiting component 3 and the nut 12, further preventing the nut 12 and the bolt body 11 from rotating relative to each other.

[0024] In this embodiment, the pressing component includes a locking screw 41 and a pressing block 42. One end of the pressing block 42 is used to press against the limiting component 3. The other side of the pressing block 42 has a through hole. The locking screw 41 passes through the through hole and is set in the mounting ring 2. The nut of the locking screw 41 presses the pressing block 42 against the wall.

[0025] Specifically, the mounting ring 2 has a threaded hole for the installation of the locking screw 41, and the mounting ring 2 is fixedly installed on the nut 12 by welding; one end of the pressure block 42 is pressed against the limiting component 3, and the other end of the locking screw 41 passes through the pressure block 42 and is connected to the mounting ring 2 by threads.

[0026] It is worth mentioning that glue can be applied between the mounting ring 2 and the locking screw 41 to further improve the stability of the connection and installation.

[0027] Preferably, four pressure blocks 42 are arranged in a circumferential array along the circumferential direction of the screw body to improve the overall stability of the press-fitting.
