[0033] The lower surface of the housing is provided with at least one heat dissipation groove 11, and the inner groove wall of the heat dissipation groove 11 is fixedly connected to the blocking net 2;

[0034] The heat dissipation component 3 is arranged inside the housing 1, and the heat dissipation component 3 includes at least one fan 31 and an electronic board 32. The fan 31 is located above the heat dissipation slot 11 and is coaxial with the heat dissipation slot 11. The side of the electronic board 32 is fixedly connected to the inner wall of the housing 1. A heat dissipation layer 33 is arranged below the electronic board 32, and the side of the heat dissipation layer 33 is also fixedly connected to the inner wall of the housing 1. The heat dissipation layer 33 is provided with at least one through slot 34, and the inner slot wall of the through slot 34 is fixedly connected to the outer shell of the fan 31.

[0035] The support assembly 4 is arranged at the corner of the lower end of the shell 1, and the support assembly 4 includes four mounting frames 41, two rotating rods 42 and four supporting legs 43. The side of the mounting frame 41 is fixedly connected to the corner of the shell 1, and the mounting frame 41 is provided with a through hole, which is fixedly connected to the rotating rod 42, and the surface of the rotating rod 42 is rotatably connected to the top of the supporting leg 43.

[0036] In this embodiment, when the signal transmission device is working, the heat dissipation device of the signal transmission device can drive the flow of air in the shell 1 through the rotation of the fan 31, take away the heat generated by the electronic board 32 when it is working, and dissipate the heat of the electronic board 32, thereby preventing the electronic board 32 from being damaged by high temperature.

[0037] like Figure 2 As shown, in a specific embodiment, the support leg 43 includes a sliding spring 431, a toggle plate 432 and a positioning column 433;

[0038] A sliding groove 44 is provided on the upper surface of one end of the supporting leg 43 close to the mounting frame 41, and the groove wall of the sliding groove 44 is fixedly connected to the sliding spring 431, and the upper end of the sliding spring 431 is provided with the toggle plate 432, and the side surface of the toggle plate 432 is slidably connected to the groove wall of the sliding groove 44, and the upper surface of the toggle plate 432 is fixedly connected to the positioning column 433, and the positioning column 433 is slidably connected to the positioning groove 45 set on the mounting frame 41.

[0042] In this embodiment, the right-angle setting of the mounting frame 41 and the positioning function of the positioning column 433 enable the support leg 43 to be in a horizontal or vertical state with the lower surface of the housing 1. When the position of the support leg 43 needs to be adjusted, the toggle plate 432 is pressed downward, and then the support leg 43 is rotated so that the support leg 43 rotates with the rotating rod 42 as the center of the circle. When the support leg 43 rotates to the other right-angle end of the mounting frame 41, the positioning column 433 will be restored under the action of the sliding spring 431 to complete the fixation;

[0043] The setting of the support assembly 4, through the setting of the support legs 43, prevents the shell 1 from contacting the desktop, thereby preventing the desktop from being damp and causing water to seep into the shell 1, which may further cause damage to the internal electronic board 32. In addition, the setting of the support legs 43 can increase the space between the bottom of the shell 1 and the desktop, thereby improving the heat dissipation effect. In addition, by arranging a pad 434 on the side of the support leg 43, when the signal transmission device is installed on the wall, a gap will still be left at the vent end of the shell 1 of the heat dissipation device, thereby improving the heat dissipation capacity of the signal transmission device.

[0044] like Figure 3 and Figure 4 As shown, in a specific embodiment, the heat dissipation device further includes: at least one dust sweeping component 5;

[0045] The dust sweeping assembly 5 is arranged on the inner and outer surfaces of the blocking net 2, and the dust sweeping assembly 5 includes an outer dust sweeping frame 51 and an inner dust sweeping frame 52;

[0046] The end of the outer dust sweeping frame 51 is slidably connected to the outer surface of the blocking net 2 ; the end of the inner dust sweeping frame 52 is slidably connected to the inner surface of the blocking net 2 .

[0047] like Figure 3 and Figure 4 As shown, in a specific embodiment, the dust sweeping assembly 5 further includes a rotating column 53, the rotating column 53 passes through the center of the blocking net 2, and the surface of the rotating column 53 is rotatably connected to the blocking net 2;

[0052] The button 6 is fixedly connected to the sliding rod 7, and the sliding rod 7 slides through the side of the shell 1, and the end of the sliding rod 7 away from the button 6 is fixedly connected to the first curved rod 57, one end of the first curved rod 57 is hinged to one end of the second curved rod 58, and the other end of the second curved rod 58 is hinged to the other end of the spur gear row 55, and the side of the first curved rod 57 facing away from the sliding rod 7 is fixedly connected to the spring 8, and the other end of the spring 8 is fixedly connected to the inner wall of the shell 1.

[0053] In this embodiment, when the heat dissipation device of the signal transmission device is used for a long time, dust will definitely adhere to the surface of the blocking net 2, and the dust will block the blocking net 2 and affect the heat dissipation of the shell 1. At this time, it is only necessary to press the button 6, and the button 6 drives the sliding rod 7 to move toward the inside of the shell 1, and then drives the first curved rod 57 to move and squeeze the spring 8. At the same time, in the process of the movement of the first curved rod 57, the second curved rod 58 is also driven to move. Under the limiting effect of the limiting rod 56 on the spur gear row 55, the spur gear row 55 can only move horizontally. The lateral movement of the spur gear row 55 can drive the gear ring 54 to rotate, and further drive the rotating column 53 to rotate, thereby driving the outer dust sweeping frame 51 and the inner dust sweeping frame 52 to rotate, and the dust on the blocking net 2 is removed. After releasing the button 6, the first curved rod 57 will be reset under the action of the spring 8, and then drive the spur gear row 55 to reset again, so that the gear ring 54 rotates in the opposite direction.

[0054] The dust sweeping assembly 5 is provided to sweep the surface of the blocking net 2 by rotating the outer dust sweeping frame 51 and the inner dust sweeping frame 52, thereby solving the problem of the heat dissipation of the heat dissipation device of the signal transmission device being affected by the dust accumulation on the surface of the blocking net 2 when the heat dissipation device is used for a long time.

[0055] In a specific embodiment, the number of the heat dissipation slots 11, the blocking net 2, the fan 31, the through slots 34 and the dust sweeping components 5 is the same.

[0056] In summary, the heat dissipation device of a signal transmission device provided by the embodiment of the utility model can drive the flow of air in the shell through the rotation of the fan, take away the heat generated by the electronic board when it is working, and dissipate the heat of the electronic board, thereby preventing the electronic board from being damaged by high temperature; through the setting of the supporting legs, the shell will not contact the desktop, thereby preventing the desktop from being damp and causing water seepage into the shell, and further causing the possibility of damage to the internal electronic board; and through the setting of the supporting legs, the space between the bottom of the shell and the desktop can be increased to improve the heat dissipation effect, and by arranging raising blocks on the sides of the supporting legs, when the signal transmission device is installed on the wall, there will still be a gap at the vent end of the shell, further ensuring the heat dissipation capacity of the signal transmission device; by rotating the outer dust sweeping rack and the inner dust sweeping rack, the surface of the blocking net is swept, thereby solving the problem of the signal transmission device affecting heat dissipation due to dust accumulation on the surface of the blocking net when in long-term use.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention.
