Description

Technical Field

[0001] This utility model relates to the field of nut technology, and in particular to a high-temperature resistant and stable connection nut. Background Technology

[0002] In existing nut and bolt connection methods, the connection and fixation usually rely solely on the internal threads of the nut and the bolt. This single fixing method is prone to loosening in some high-temperature, high-vibration, or high-stress working environments, affecting the stability and reliability of the connection.

[0003] Moreover, when traditional nuts are installed using tools (such as adjustable wrenches), the imperfect structural design of the nuts and the lack of effective support and auxiliary structures may result in an unstable connection between the tool and the nut, affecting installation efficiency and effectiveness. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant and stable connection nut.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-temperature resistant and stable connection nut includes a nut body, auxiliary blocks are fixedly installed on three equidistant surfaces of the nut body, at least two support frames are fixedly installed at the upper and lower ends of the nut body, and each support frame on the same surface is equidistantly arranged, and bracket sleeves are provided above and below the nut body.

[0009] Preferably, each of the bracket sleeves is fitted over the support frame, the surface of each support frame is divided into two sections, a first threaded groove is formed on the surface of each support frame near the end, and a second threaded groove is formed on the inner wall of each bracket sleeve. In the initial state, each bracket sleeve is located on one side of the bottom end of the support frame.

[0010] Preferably, the upper and lower ends of the nut body are fixedly installed with partition plates, each auxiliary block is located at the corner of the nut body, and each auxiliary block has an arc-shaped surface. The inner wall of the nut body is provided with a reinforcing thread surface, and the inner wall of the reinforcing thread surface is provided with at least two rectangular grooves. The top and bottom of the inner wall of each rectangular groove are fixedly installed with a first reinforcing frame, and a second reinforcing frame is fixedly installed between the two first reinforcing frames. Side support rods are fixedly installed between the two sides of the second reinforcing frame and the two sides of the inner wall of the rectangular groove.

[0011] (III) Beneficial Effects

[0012] 1. Place the nut body over the bolt. The support brackets at both ends of the nut body are located outside the bolt. Each support bracket is arc-shaped inside and out. The user rotates the nut body, and the internal threads of the nut body connect with the bolt. After the nut body and bolt are installed, the user rotates the two bracket sleeves. The two brackets rotate over the multiple support brackets and squeeze the multiple support brackets inward. At this time, the nut body and bolt are fixed. At the same time, the multiple support brackets at both ends clamp the bolt, forming a triple fixation, which greatly improves the connection stability between the nut body and the bolt.

[0013] 2. The inner walls of the two jaws of the adjustable wrench contact the two auxiliary blocks, which provide good support and improve the connection between the adjustable wrench and the nut body, thus improving the installation capability. By designing the section of the support frame near the nut body as a smooth surface, it is easy to rotate the support sleeve. The curved surface of the auxiliary block reduces the space occupied.

[0014] Third, by setting a strong threaded surface in the nut body, multiple first reinforcing frames in the strong threaded surface can provide strong support for the whole without affecting the threaded installation. The second reinforcing frame can further improve the overall support. The side support rods on the left and right sides of the second reinforcing frame can provide support for the lateral force of the whole. Attached Figure Description

[0022] like Figures 1 to 5 As shown, the overall concept of the technical solution in this application embodiment is as follows:

[0023] To address the problems existing in the prior art, this utility model provides a high-temperature resistant and stable connection nut, including a nut body 1. Auxiliary blocks 11 are fixedly installed on three equidistant surfaces of the nut body 1. At least two support frames 14 are fixedly installed at both the upper and lower ends of the nut body 1. When the user rotates the nut body 1, the internal threads of the nut body 1 connect with the bolt. After the nut body 1 and the bolt are installed, the user rotates two bracket sleeves 17. The two bracket sleeves 17 rotate outside the multiple support frames 14 and press the multiple support frames 14 inward. At this time, the nut body 1 is fixed to the bolt, and each support frame 14 on the same surface is equidistant. Support sleeves 17 are provided above and below the nut body 1.

[0024] Each bracket sleeve 17 is fitted over the support frame 14. The surface of each support frame 14 is divided into two sections. A first threaded groove 15 is formed on the surface of each support frame 14 near its end. A second threaded groove 18 is formed on the inner wall of each bracket sleeve 17. The adjustable wrench is engaged with the surface of the nut body 1, specifically the surface without auxiliary blocks 11. At this time, the inner walls of the two jaws of the adjustable wrench contact the two auxiliary blocks 11, which provide good support and improve the connection between the adjustable wrench and the nut body 1, thus enhancing installation capability. In the initial state, each bracket sleeve 17 is located within the support frame 14. At the bottom side, partition plates 16 are fixedly installed at both the upper and lower ends of the nut body 1. Each auxiliary block 11 is located at the corner of the nut body 1, and each auxiliary block 11 has an arc-shaped surface 12. The inner wall of the nut body 1 is provided with a reinforcing thread surface 2. At least two rectangular grooves 21 are provided on the inner wall of the reinforcing thread surface 2. A first reinforcing frame 22 is fixedly installed at the top and bottom of the inner wall of each rectangular groove 21. A second reinforcing frame 23 is fixedly installed between the two first reinforcing frames 22. Side support rods 24 are fixedly installed between the two sides of the second reinforcing frame 23 and the two sides of the inner wall of the rectangular groove 21.

[0025] Working principle:

[0026] The first step involves the user placing the nut body 1 over the bolt. The support brackets 14 at both ends of the nut body 1 are located outside the bolt, and each support bracket 14 is arc-shaped both inside and out. The user rotates the nut body 1, and the internal threads of the nut body 1 connect with the bolt. After the nut body 1 and the bolt are installed, the user rotates the two bracket sleeves 17. The two bracket sleeves 17 rotate outside the multiple support brackets 14 and press the multiple support brackets 14 inward. At this time, the nut body 1 is fixed to the bolt, and at the same time, the multiple support brackets 14 at both ends clamp the bolt, forming a triple fixation, which greatly improves the connection stability between the nut body 1 and the bolt.

[0027] In the second step, when rotating the nut body 1 using the adjustable wrench, the adjustable wrench is locked on the surface of the nut body 1, and on the surface without the auxiliary block 11. At this time, the inner walls of the two jaws of the adjustable wrench are in contact with the two auxiliary blocks 11. The two auxiliary blocks 11 provide good support, improve the connection between the adjustable wrench and the nut body 1, and improve the installation capability. By designing the section of the support frame 14 near the nut body 1 as a smooth surface, it is convenient to rotate the bracket sleeve 17. The arc-shaped surface 12 on the surface of the auxiliary block 11 can reduce the space occupied. The partition plate 16 can form a certain gap between the bracket sleeve 17 and the nut body 1, which is convenient for the user to rotate.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
