Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-5 As shown, an outdoor broadcast transmitter includes a cabinet body 1, a back cover 2 is provided on the back of the cabinet body 1, and the cabinet body 1 includes a heat dissipation fan 112 and a transmitting terminal 114; further comprising: the cabinet body 1 includes a cabinet body 101, a mounting groove 105 is provided in the middle of the back of the cabinet body 101, and a water baffle 106 is fixedly connected to the inner wall of the cabinet body 101 and near the mounting groove 105, and a gap is left between the two sides of the water baffle 106 and the inner wall of the cabinet body 101; wherein, a plurality of side grooves 107 are provided on both sides of the outer wall of the water baffle 106, and the inner side of each side groove 107 is rotatably connected to a support wheel 108, and a strap threading hole 109 is provided on the surface of the water baffle 106 and near each side groove 107, as shown Figure 3As shown, if the cable moves after it abuts against the support wheel 108, it drives the support wheel 108 to rotate in the side groove 107, thereby reducing the friction of the cable directly contacting the side of the water baffle 106, thereby avoiding damage to the cable skin;

[0028] The lower end of the surface of the water baffle 106 is fixedly mounted with a bottom plate 110. Both sides of the bottom plate 110 are fixedly connected to the inner wall of the cabinet body 101. The surface of the bottom plate 110 is provided with a plurality of drain holes 111. Figure 3 As shown, the drain hole 111 drains the accumulated water dripping on the bottom plate 110 to prevent the accumulated water from generating moisture in the cabinet;

[0029] A cabinet door 102 is hinged on one side of the front of the cabinet body 101, and an observation window 103 is inlaid on the inner wall of the cabinet door 102. A plurality of support plates 104 are fixedly installed on the inner wall of the cabinet body 101 and located in front of the water baffle 106. Each support plate 104 is arranged equidistantly along the length direction of the cabinet body 101, and the top surface of each support plate 104 is in active contact with the transmitting terminal 114. A plurality of cooling fans 112 are fixedly installed on both sides of the cabinet body 101, and each cooling fan 112 on both sides is arranged equidistantly along the length direction of the cabinet body 101, and a shielding plate 113 is fixedly connected to the outer wall of the cabinet body 101 and located on the outside of the cooling fan 112. Figure 1-Figure 2 As shown, the outer side of the shield 113 is inclined, and the shield guides the rainwater falling from above to the outside of the cabinet body 101, thereby preventing the rainwater from entering the interior of the cabinet body 101 through the heat dissipation fan 112;

[0030] The rear cover 2 includes a body 201, a convex portion 202 is provided in the middle of the body 201, a plurality of screws 204 are connected to the edge sides of the surface of the body 201, and handles 203 are symmetrically fixedly connected to the middle of both sides of the body 201. A plurality of heat dissipation windows 205 are embedded and fixed in the middle of the surface of the convex portion 202. The heat dissipation windows 205 are arranged equidistantly along the length direction of the body 201, and cable holes 206 are opened on the surface of the body 201 and located between the heat dissipation windows 205. The inner side wall of each cable hole 206 is fixedly connected to a sealing ring 207. Figure 4 As shown, when the cable passes through the cable hole 206, since the cable hole 206 is provided on the outside of the protrusion 202, the cable will not bend too much after it hits the side of the support wheel 108, thereby preventing the cable from breaking;

[0031] The inner side of the mounting groove 105 is movably mounted on the panel 201. The cabinet body 101 extends to the inner side of the mounting groove 105 and is threadedly connected to each screw 204. Figure 3 As shown, the inner wall of the cabinet body 101 extends to the inner side of the mounting groove 105 and is provided with a threaded hole, and the cabinet body 201 is fixed by screwing a screw 204 into the threaded hole.

[0032] The working principle of this utility model:

[0033] When the device is in use, the transmitting terminal is placed above the support plate 104, and the external cable is introduced into the cabinet body 101 through the installation slot 105, and the outer side of the cable is placed against the outer side of the support wheel 108. Then, the end is passed around both sides of the water baffle 106 and connected to the transmitting terminal 114. Then, the strap is inserted into the strap insertion hole 109, and the outer side of the cable is placed inside the strap. The strap is tightened to fix the cable.

[0034] Next, pass the other end of the cable through the cable hole 206. The outer side of the cable squeezes the sealing ring 207 in the cable hole 206, so that the sealing ring 207 fills the gap in the cable hole 206. After the cable is passed through the rear cover 2, place the cabinet body 201 against the inner side of the installation groove 105, and screw 204 through the cabinet body 201 and tighten it to the inner wall of the cabinet body 101.

[0035] When the cabinet body 101 is cooled, the cooling fan 112 is started to discharge the hot air inside the cabinet body 101 to the outdoor environment, and the low-temperature air in the outdoor environment enters the cabinet body 101 through the cooling window 205, thereby improving the cooling effect of the transmitting terminal 114.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
