Description

Technical Field

[0001] The invention relates to the technical field of antennas, in particular to an antenna bracket for broadcasting and television engineering. Background Art

[0002] Radio and television are news dissemination tools that transmit sound, images, and videos through radio waves or wires. Specifically, the broadcasting of only sound is called sound broadcasting, and the broadcasting of images and sound is called television broadcasting. At present, with the large-scale application of radio and television, in order to further facilitate use, researchers in related fields have also made relative improvements to the antenna bracket of radio and television. For example, the patent document with application number CN202420007921.X discloses that "the antenna bracket for radio and television engineering drives the adjustment worm gear 2 and the adjustment worm gear 2 to rotate through the driving component 2, which can drive the connecting fork frame and the support frame to move, thereby adjusting the elevation angle of the satellite dish body. At the same time, the driving component 1 drives the adjustment worm gear 1 and the transmission worm gear 1 to rotate, and drives the rotating table to rotate as a whole, so as to adjust the direction of the satellite dish body. At the same time, remote control can be achieved through the wireless transceiver module in the electrical control box, which reduces the difficulty of operation and facilitates adjustment during the installation and subsequent use of the satellite dish body."

The structural surfaces of the front and rear ends of the U-shaped spur plate 9 are fixedly connected with auxiliary slide rails, and a through-state guide groove is opened on the top of the other side of the support frame 2, which can be engaged with the corresponding auxiliary slide rail, thereby improving the stability of the reciprocating movement of the U-shaped spur plate 9.

[0025] Working principle: When in use, for adjusting the use angle of the satellite pot body 1, the brake servo motor 63 can be started, and the output end of the brake servo motor 63 drives the lead screw 61 to rotate synchronously, and then the lead screw 61 engages with the transmission nut 62, and the nut 62 drives the compound spur plate 5 to move through the linkage plate, and finally the compound spur plate 5 engages with the transmission gear shaft 4 to adjust the inclination angle of the satellite pot body 1, and the arc sleeve 13 moves synchronously with the satellite pot body 1. After adjusting to the appropriate angle, the two screw sleeves 142 are turned to make the two screw sleeves 142 move spirally on the surface of the U-shaped threaded rod 141, and finally the arc sleeve 13 is clamped and limited, so as to realize the secondary locking and limiting of the adjusted satellite pot body 1; When the satellite dish body 1 is subjected to vibration during use, the damping sleeve 17 shares the vibration pressure of the satellite dish body 1 and uses the guidance and reciprocating elastic reset of the elastic rod 18 to perform damping and buffering on the satellite dish body 1, thereby improving the stability of the satellite dish body 1 during use. During the normal use of the satellite dish body 1, the solar panel uses the top space of the supporting frame 2 to generate solar energy, thereby improving the cleaning effect of the overall device. When the whole device is facing bad weather, the two screw sleeves 142 are screwed to make the two screw sleeves 142 away from the arc sleeve plate 13, the electromagnet 12 is turned off, and the brake servo motor 63 is started. The output end of the brake servo motor 63 drives the lead screw 61 to rotate synchronously, and then the lead screw 61 engages with the transmission nut 62, and the nut 62 drives the composite spur plate 5 to move through the linkage plate, so that the composite spur plate 5 engages with the transmission gear shaft 4 to adjust the angle of the satellite dish body 1, and until the satellite dish body 1 changes from the inclined state to the horizontal state; During the flipping process of the satellite dish body 1 from tilted to horizontal, the transmission shaft 11 will be synchronously tilted and pushed, and the transmission shaft 11 that moves to give way will synchronously push the U-shaped spur plate 9, and the two ends of the U-shaped spur plate 9 will synchronously engage with the two transmission gears 8, eventually making the adjustment plate 7 and the solar panel flip 180 degrees on the top of the supporting frame 2, and then cooperate with the top structure of the supporting frame 2 to shield and protect the horizontal satellite dish body 1 and the solar panel, thereby minimizing the chance of damage to the satellite dish body 1 and the solar panel in harsh environments.
