However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1 to 11 As shown, a heat dissipation connecting shaft for heavy-duty trucks includes a hollow connecting shaft 1. A first cylinder 2 is fixedly connected to the inner wall of the hollow connecting shaft 1. A second cylinder 3 is sleeved on the surface of the first cylinder 2. A heat dissipation column 4 is fixedly connected to the surface of the second cylinder 3. The right side of the heat dissipation column 4 is fitted against the left side of the hollow connecting shaft 1. Circular holes 5 are opened on both the upper and lower sides of the second cylinder 3. A cylinder 6 is fixedly connected to the inner wall of the circular holes 5. A first groove 7 is opened on the left side of the first cylinder 2. The inner wall of the first groove 7 is fitted against the surface of the cylinder 6. The inner wall of the first cylinder 2 is fitted with... A screw 8 is provided, and a second groove 9 is provided on the right side of the screw 8. The inner wall of the second groove 9 is in contact with the surface of the cylinder 6. A nut 10 is threadedly connected to the surface of the screw 8. The nut 10 is located on the right side of the first cylinder 2. A third cylinder 11 is fixedly connected to the surface of the hollow connecting shaft 1. A third groove 12 is provided on the inner wall of the third cylinder 11. A fourth groove 13 is provided on the right side of the heat dissipation column 4. An arc plate 14 is fixedly connected to the inner wall of the fourth groove 13. The inner wall of the third groove 12 and the surface of the hollow connecting shaft 1 are both in contact with the surface of the arc plate 14.

[0031] The axis of the arc plate 14 coincides with the axis of the hollow connecting shaft 1.

[0032] A fourth cylinder 15 is fixedly connected to the right side of the nut 10. A vertical plate 16 is fitted to the inner wall of the fourth cylinder 15 and the inner wall of the second groove 9. A fifth groove 17 is opened on both the upper and lower sides of the vertical plate 16. A first ring 18 is fixedly connected to the inner wall of the fourth cylinder 15. The left and right sides of the first ring 18 are fitted to the inner wall of the fifth groove 17. The axis of the fourth cylinder 15 coincides with the axis of the screw 8. The outer diameter of the fourth cylinder 15 is smaller than the distance between opposite sides of the nut 10.

[0033] It should be noted that when the second cylinder 3 is fitted onto the first cylinder 2, the first cylinder 2 supports the second cylinder 3. When the arc plate 14 on the heat dissipation column 4 is inserted into the third groove 12, the heat dissipation column 4 can rotate with the hollow connecting shaft 1 through the cooperation of the arc plate 14 and the third groove 12. When the screw 8 is inserted into the first cylinder 2, the screw 8 cannot rotate in the first cylinder 2 through the cooperation of the second groove 9 and the cylinder 6. When the nut 10 is screwed onto the screw 8, the heat dissipation column 4 can be fixed on the hollow connecting shaft 1 through the cooperation of the first cylinder 2, the second cylinder 3, the cylinder 6, the screw 8, the second groove 9, and the nut 10. When the nut 10 is unscrewed from the screw 8, the heat dissipation column 4 can be directly separated from the hollow connecting shaft 1.

[0034] The vertical plate 16 can rotate inside the fourth cylinder 15, and through the cooperation of the first ring 18 and the fifth groove 17, the vertical plate 16 cannot be separated from the fourth cylinder 15. When the nut 10 is screwed onto the screw 8, the vertical plate 16 will be inserted into the second groove 9. The vertical plate 16 can prevent the opening of the second groove 9 from deforming, so that there will be no gap between the nut 10 and the screw 8 due to the deformation of the opening of the second groove 9.

[0035] like Figures 1 to 12 As shown, a second ring 19 is fitted on the surface of the screw 8. The second ring 19 is located between the first cylinder 2 and the nut 10. A baffle 20 is fixedly connected to the surface of the second ring 19. A sixth groove 21 is provided on the right side of the hollow connecting shaft 1. The inner wall of the sixth groove 21 is in contact with the surface of the baffle 20. A third ring 22 is fixedly connected to the left side of the baffle 20. An arc-shaped heat sink 23 is fitted to the inner wall of the third ring 22, the inner wall of the third groove 12, and the surface of the hollow connecting shaft 1. The left and right sides of the arc-shaped heat sink 23 are in contact with the left side of the baffle 20 and the right side of the arc plate 14, respectively. A heat sink fin 24 is fixedly connected to the surface of the arc-shaped heat sink 23.

[0036] The axis of the arc-shaped heat sink 23 coincides with the axis of the hollow connecting shaft 1, and the number of arc-shaped heat sinks 23 is the same as the number of baffles 20.

[0037] It should be noted that when the nut 10 is screwed onto the screw rod 8, the second ring 19 can be fixed onto the screw rod 8 through the cooperation of the screw rod 8, the nut 10 and the first cylinder 2. And through the cooperation of the third cylinder 11, the third groove 12, the arc plate 14, the second ring 19, the baffle 20, the sixth groove 21 and the third ring 22, the arc-shaped heat sink 23 can be fixed onto the hollow connecting shaft 1. When the nut 10 is unscrewed from the screw rod 8, the arc-shaped heat sink 23 can be removed from the hollow connecting shaft 1, so that maintenance personnel can replace the damaged arc-shaped heat sink 23 and heat sink fins 24. When the second ring 19 is fitted onto the screw rod 8, the baffle 20 can be limited by the sixth groove 21.

[0038] The working principle of this utility model is as follows: When replacing the heat dissipation column 4, first unscrew the nut 10 from the screw 8 by rotating the nut 10. Then, by pulling the arc plate 14 out of the third groove 12, the heat dissipation column 4 can be separated from the hollow connecting shaft 1. When fixing the heat dissipation column 4 onto the hollow connecting shaft 1, first, put the second cylinder 3 on the first cylinder 2, and insert the arc plate 14 into the third groove 12. Then, insert the screw 8 into the first cylinder 2, and make the inner wall of the second groove 9 contact the cylinder 6. At this time, the screw 8 cannot rotate inside the first cylinder 2 due to the cooperation of the second groove 9, the cylinder 6 and the first groove 7. Then, the nut 10 is screwed onto the screw 8, and the screw 8 cannot slide inside the first cylinder 2 due to the cooperation of the first cylinder 2, the second cylinder 3, the cylinder 6, the screw 8, the second groove 9 and the nut 10. At this time, the heat dissipation column 4 can be fixed on the hollow connecting shaft 1 through the cooperation of the arc plate 14 and the third groove 12. The heat dissipation column 4 can rotate together with the hollow connecting shaft 1.

[0039] When it is necessary to replace the arc-shaped heat sink 23 and the heat dissipation fins 24, first unscrew the nut 10 from the screw 8 by turning the nut 10. Then, separate the third ring 22 from the arc-shaped heat sink 23 and remove the second ring 19 from the hollow connecting shaft 1. Then, remove the arc-shaped heat sink 23 from the hollow connecting shaft 1 by pulling it out of the third groove 12. When it is necessary to install the arc-shaped heat sink 23, first insert the left side of the arc-shaped heat sink 23 into the third groove 12, and then put the second ring 19 on the screw. The screw rod 8 is used to attach the third ring 22 to the right side of the arc-shaped heat sink 23. Then, the nut 10 is screwed onto the screw rod 8, and the first cylinder 2 and the nut 10 clamp the second ring 19. At this time, through the cooperation of the screw rod 8, the nut 10, the first cylinder 2 and the second ring 19, the baffle 20 can be fixed in the sixth groove 21. And through the cooperation of the third cylinder 11, the third groove 12, the arc-shaped plate 14, the second ring 19, the baffle 20, the sixth groove 21 and the third ring 22, the arc-shaped heat sink 23 can be fixed on the hollow connecting shaft 1.
