Description

Technical Field

[0001] The utility model belongs to the field of bolts, and particularly relates to an internal and external hexagonal through-hole heat dissipation bolt. Background Art

[0002] In ultra-high voltage power equipment, insulating fasteners play a crucial role, mainly used for fixing and connecting various components to ensure the safe and stable operation of the equipment. Most of the insulating fasteners used in the current market rely on imported products, which usually adopt materials such as laminated wood and fiberboard and are formed by machining.

[0003] During the operation of high-voltage equipment, due to the extremely high electric field intensity and large current, the heat generated by the equipment is concentrated. However, the traditional insulating materials have a low thermal conductivity and cannot effectively dissipate heat, which easily leads to the accelerated aging of the insulating materials, and then causes the phenomenon of discharge breakdown, seriously affecting the service life and safety of the equipment. Content of the Utility Model

[0004] Based on the problems mentioned in the above background art, the utility model provides an internal and external hexagonal through-hole heat dissipation bolt.

[0005] The technical solution adopted by the utility model is as follows: an internal and external hexagonal through-hole heat dissipation bolt, including a connection block and a connection column. A sinking groove is arranged at the top of the connection block; the connection column is integrally formed at the bottom of the connection block, and a thread helix is arranged on the connection column; a cylindrical opening that penetrates the connection column and the connection block is arranged along the axis of the connection column.

[0006] Further, a structural column is arranged in the sinking groove. A conical surface connected to the top of the cylindrical opening is arranged on the structural column, and the structural column is penetrated by the cylindrical opening.

[0007] Further, the top surface of the structural column is lower than the top surface of the connection block, and the top surface of the cylindrical opening is higher than the bottom of the sinking groove.

[0008] Further, the outer diameter of the structural column is smaller than the outer diameter of the connection column.

[0009] Further, the cross-section of the sinking groove is hexagonal.

[0010] Further, the ratio of the diameter of the cylindrical opening to the diameter of the connection column is 5:16.

[0011] Advantages of the Utility Model

[0012] 1. By arranging a through cylindrical opening on the integrally formed connection block and connection column, a hollow design is carried out on the insulator without affecting the strength of the insulating product, solving the problem of exhaust heat dissipation. The heat dissipation effect of the hollow bolt is better than that of the solid bolt.

[0013] 2. Through the structural design where the conical surface on the structural column is connected to the cylindrical opening, the cone has a diverging effect, resulting in better heat dissipation. The setting of the structural column not only extends the heat dissipation channel outside the sunken groove to ensure the heat dissipation effect, but also does not affect the tool from reaching into the sunken groove to turn the bolt.

[0020] As Figures 1 to 3 shown, an internal and external hexagon through-hole heat-dissipating bolt includes a connecting block 1 and a connecting column 3. A sunken groove 2 is provided at the top of the connecting block 1; the connecting column 3 is integrally formed at the bottom of the connecting block 1, and a thread helix is provided on the connecting column 3; a cylindrical opening 4 that penetrates the connecting column 3 and the connecting block 1 is provided along the axis of the connecting column 3.

[0021] By adopting the above technical solution, a through cylindrical opening 4 is provided on the integrally formed connecting block 1 and connecting column 3, and a hollow design is carried out on the insulator without affecting the strength of the insulating product, solving the problem of exhaust heat dissipation. The hollow bolt has better heat dissipation effect than the solid bolt.

[0022] As a preferred solution, a structural column 5 is provided in the sunken groove 2. A conical surface 6 connected to the top of the cylindrical opening 4 is provided on the structural column 5, and the structural column 5 is penetrated by the cylindrical opening 4. Through the structural design where the conical surface 6 on the structural column 5 is connected to the cylindrical opening 4, the cone has a diverging effect, resulting in better heat dissipation.

[0023] As a preferred solution, the top surface of the structural column 5 is lower than the top surface of the connecting block 1, and the top surface of the cylindrical opening 4 is higher than the bottom of the sunken groove 2. The setting of the structural column 5 not only extends the heat dissipation channel outside the sunken groove 2 to ensure the heat dissipation effect, but also does not affect the tool from reaching into the sunken groove 2 to turn the bolt.

[0024] As a preferred solution, the outer diameter of the structural column 5 is smaller than the outer diameter of the connecting column 3. Matching the standardized design of the sinking groove 2 facilitates the use of standard parts such as an internal hexagonal wrench to turn the bolts.

[0025] As a preferred solution, the cross-section of the sinking groove 2 is hexagonal. The hexagonal structural design facilitates the use of tools such as wrenches for turning, and the stress distribution is uniform.

[0026] As a preferred solution, the ratio of the diameter of the columnar opening 4 to the diameter of the connecting column 3 is 5:16. While not affecting the strength of the fastener, it provides the maximum heat dissipation range.

[0027] The above has introduced the present utility model in detail. The description of the specific embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
