[0023] It should be noted that since the existing heat dissipation structure has poor heat dissipation efficiency and is cumbersome to install, in order to solve the problems arising during the use of the existing heat dissipation structure, this solution solves the problem of poor heat dissipation efficiency and cumbersome installation of the existing heat dissipation structure by adding a heat dissipation component 4 at the bottom of the top plate 5 and using the various components inside the limit plate 10.

[0024] In a further preferred embodiment of the present invention, Figure 1 , 2 As shown in , and 3, the inner walls on the left and right sides of the heat sink 41 are commonly connected with a horizontal plate 412 near the bottom center, and a rotating rod 48 is provided at the top of the horizontal plate 412 near the center.

[0025] In this embodiment, when the structure is installed on the servo motor for heat dissipation, the staff drives the rotating rod 48 to rotate. When the rotating rod 48 rotates, it can drive the two driving bevel gears 46 to rotate synchronously. When the two driving bevel gears 46 rotate, they are meshed with the adjacent driven bevel gears 47, thereby driving the two driven bevel gears 47 to rotate, so that the two driven bevel gears 47 can drive the two fan blades 44 through the two rotating shafts 42, so that the two fan blades 44 can blow air downward, and the wind generated by the two fan blades 44 can be discharged from the inner cavity of the heat dissipation box 41 through the two air guides 45 and blown onto the servo motor, thereby accelerating the air flow rate on the servo motor side, so as to quickly take away the heat generated by the servo motor to complete the heat dissipation work, thereby achieving the purpose of improving the heat dissipation efficiency of the servo motor.

[0026] In a further preferred embodiment of the present invention, Figure 2 and 3 As shown, a driven gear 43 is connected to the rotating rod 48 near the center, a driving gear 49 is provided on the top of the driven gear 43, and the driven gear 43 and the driving gear 49 are meshed with each other.

When the driving gear 49 rotates, it meshes with the driven gear 43, thereby driving the driven gear 43 to rotate, so that the driven gear 43 can quickly drive the rotating rod 48 to rotate.

[0028] In a further preferred embodiment of the present invention, Figure 2 and 3 As shown, an L-shaped connecting rod 411 is connected to the right side of the driving motor 410 near the center, and the shorter end of the L-shaped connecting rod 411 is connected to the top inner wall of the heat sink 41 near the center of the right side.

[0029] In this embodiment, the driving motor 410 is fixed inside the heat dissipation box 41 by an L-shaped connecting rod 411 , so that the driving motor 410 can work stably.

[0030] In a further preferred embodiment of the present invention, Figure 1 , 2As shown in , 4 and 5, a through slot is opened on the driving plate 8 near the top center, and a roller 12 is arranged near the bottom center of the inner cavity of the through slot, and the front and rear ends of the roller 12 both pass through the inner cavity of the through slot, and the front and rear ends of the roller 12 are movably connected with the front and rear inner walls of the fixed box 7 near the bottom center respectively, and a linkage gear 11 is connected to the roller 12 near the center, and a linkage rack 13 is arranged on the left side of the linkage gear 11, and the left side of the linkage rack 13 is connected to the left inner wall of the through slot near the center, and the linkage rack 13 is meshed with the linkage gear 11.

[0031] In this embodiment, when the structure is to be installed together with the servo motor for use, since the structure is welded to the protective plate 1 through two fixing rods 2, the structure and the protective plate 1 form a whole for use. During installation, the staff places the servo motor on the arc-shaped fixing groove on the protective plate 1, and then the staff drives the roller 12 to rotate in the opposite direction, so that the roller 12 drives the linkage gear 11 to rotate in the opposite direction. When the linkage gear 11 rotates in the opposite direction, it meshes with the linkage rack 13, thereby driving the linkage rack 13 to move downward, so that the linkage rack 13 quickly drives the drive plate 8 to move out of the inner cavity of the fixed box 7, so that the drive plate 8 can quickly drive the positioning plate 3 to move downward on the two fixing rods 2 through the heat dissipation box 41, so that the positioning plate 3 can quickly move downward and contact the top of the servo motor, so that the structure can be quickly installed together with the servo motor for use, thereby achieving the purpose of convenient installation.

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, a coupling shaft is connected to the front end of the rotating roller 12 near the center, a rotating hole is opened at the front side of the fixed box 7 near the bottom center, the front end of the coupling shaft passes through the inner cavity of the rotating hole and is connected to the rotating handle 6.

[0033] In this embodiment, the staff rotates the handle 6 in the reverse direction, so that the handle 6 can quickly drive the roller 12 to rotate in the reverse direction synchronously.

[0034] In a further preferred embodiment of the present invention, Figure 2 and 4 As shown, the inner wall of the top of the fixed box 7 is connected to limit rods 9 near the center of the left and right sides, and the bottom ends of the two limit rods 9 are connected to the top of the top plate 5 near the center, and the two limit rods 9 are sleeved with limit plates 10 near the top, and the adjacent sides of the two limit plates 10 are respectively connected to the left and right sides of the driving plate 8 near the top center.

[0035] In this embodiment, when the driving plate 8 is moved out from the inner cavity of the fixed box 7, the driving plate 8 can drive the two limit plates 10 to slide downward on the two limit rods 9, thereby limiting the position of the driving plate 8, so that the driving plate 8 can be smoothly moved out of the inner cavity of the fixed box 7.
