Description

Technical Field

[0001] The utility model relates to a broadcast signal transmitter, in particular to an adjusting device for a broadcast signal transmitter, belonging to the technical field of broadcast signal transmitters. Background Art

[0002] A television transmitter refers to a radio device that modulates an image video signal and an audio signal conforming to a certain television broadcast standard onto a fixed intermediate frequency, then converts the frequency to a specified radio frequency through frequency conversion, amplifies the power to reach a specified power level, and finally feeds it to a designated load antenna so that the signal waveform meets the radio frequency characteristic requirements of the television broadcast standard. Radio devices are exposed to the open environment for a long time and are affected by the surrounding environment, resulting in unstable signal reception of the television transmitter. Therefore, it is necessary to appropriately adjust the television transmitter to meet people's usage requirements.

[0003] Chinese Patent No. CN216720268U provides an adjusting device for a radio and television signal transmitter, including a base. The upper surface of the base is fixedly connected with a driving motor through bolts. One end of the driving motor is fixedly connected with a coupling. The other end of the coupling is fixedly connected with a ball screw. A lead screw nut is sleeved on the outer surface of the ball screw. Both sides of the lead screw nut are fixedly connected with fixed connecting rods. The other ends of the fixed connecting rods are fixedly connected with sliding bases. The other side of the sliding base is rotatably connected with a first support rod through a rotating shaft. For this adjusting device for a radio and television signal transmitter, the lifting and adjusting device uses a servo motor as a power source and is driven by a ball screw, which can accurately control the lifting height and speed of the device. A sliding base is added to the rotating part between the connecting rods, which can reduce the fitting clearance and eliminate the lifting error of the device, facilitating more accurate adjustment of the signal machine by the staff.

[0004] However, although the above case can adjust the height and orientation of the transmitter, it cannot adjust the orientation angle of the transmitter, and when adjusting the height, the moving direction of the transmitter is not on a vertical axis.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

The support frame 401 is rotatably connected to a rotating block 405 through a shaft. The support frame 401 is fixed to the top of the steering assembly 300. A motor three 402 is fixed to one side of the support frame 401. A lead screw 403 is fixed to the output shaft end of the motor three 402. A toothed rack 404 is threadedly connected to one side of the lead screw 403. There are teeth on the top of the toothed rack 404 that mesh with the rotating block 405. The toothed rack 404 is slidably connected inside the support frame 401. One side of the toothed rack 404 meshes with the rotating block 405. The bottom of the rotating block 405 is semi-circular and has teeth. The rotating block 405 is rotatably connected inside the support frame 401. A transmitter body 406 is fixed to the end of the rotating block 405.

[0023] As a technical optimization scheme of the present utility model, the support assembly 100 includes a bottom frame 101. Support legs 102 are fixed to the bottom of the bottom frame 101. The support legs 102 function to accommodate the threaded rod 205. A limiting slide bar 103 is fixed inside the support legs 102. The limiting slide bar 103 functions to limit the rotation of the threaded rod 205. The limiting slide bar 103 slides in the limiting groove 206. A fixing plate 104 is fixed to the end of the support leg 102. Through the fixing plate 104, the device can be fixed in a suitable position. A motor one 105 is fixed to the bottom of the bottom frame 101. A bevel gear one 106 is fixed to the output shaft end of the motor one 105. The bevel gear one 106 meshes with a plurality of bevel gears two 202.

[0024] As a technical optimization scheme of the present utility model, the lifting assembly 200 includes a connecting rod 201. The connecting rod 201 functions for transitional connection. The connecting rod 201 is rotatably connected inside the bottom frame 101. A bevel gear two 202 is fixed to one end of the connecting rod 201. The bevel gear two 202 meshes with the bevel gear one 106. A worm 203 is fixed to the other end of the connecting rod 201. A worm gear 204 is meshed with one side of the worm 203. The outer ring of the worm gear 204 has teeth, and the inner ring has threads. A threaded rod 205 is threadedly connected inside the worm gear 204. A limiting groove 206 is opened on one side of the threaded rod 205. A support plate 207 is fixed to the end of the threaded rod 205.

[0025] As a technical optimization solution of the present utility model, the steering assembly 300 includes a limit ring 301. The limit ring 301 functions to limit the rotation frame 308. The limit ring 301 is fixed to the top of the support plate 207. A connecting block 302 is fixed to one side of the limit ring 301. A second motor 303 is fixed to the top of the connecting block 302. A first gear 304 is fixed to the output shaft end of the second motor 303. A rotating rod 305 is rotatably connected inside the connecting block 302. The rotating rod 305 serves as a transitional connection. A crown gear 306 is fixed to one end of the rotating rod 305. The crown gear 306 meshes with the first gear 304. A third bevel gear 307 is fixed to the other end of the rotating rod 305. The third bevel gear 307 causes the transmitter body 406 to rotate by driving the rotation frame 308. A third bevel gear 307 meshes with one side of the rotation frame 308. The rotation frame 308 is rotatably connected inside the limit ring 301.

[0026] When the present utility model is in use, by driving the first bevel gear 106 to rotate through the first motor 105, multiple second bevel gears 202 can rotate simultaneously. Thus, the worm 203 is driven to rotate by the connecting rod 201. Since the worm gear 204 is threadedly connected to the lead screw 205 and the worm gear 204 rotates inside the chassis 101, the lead screw 205 will move upward or downward under the restriction of the limit slide bar 103. Consequently, the transmitter body 406 can move up and down. By driving the first gear 304 to rotate through the second motor 303, the crown gear 306 can drive the third bevel gear 307 to rotate through the rotating rod 305. Thus, the rotation frame 308 drives the angle adjustment assembly 400 to rotate, and consequently, the orientation of the transmitter body 406 is changed. By driving the lead screw 403 to rotate through the third motor 402, the lead screw 403 drives the tooth rack 404 to slide inside the support frame 401 through a threaded connection. Since there are teeth on the top of the tooth rack 404 that mesh with the rotating block 405, when the tooth rack 404 moves, it will drive the rotating block 405 to rotate with the support frame 401 as the support. Thus, the orientation angle of the transmitter body 406 is changed.
