Description

Technical Field

[0001] This utility model relates to the field of signal transmitting device technology, and in particular to an anti-interference signal transmitting device for digital broadcast television wireless transmission. Background Technology

[0002] Digital broadcast television wireless transmission signal transmitting equipment is a core hardware system that modulates and amplifies digital audio and video signals into high-frequency radio waves, and broadcasts them to the coverage area through an antenna.

[0003] During use, the device needs to be fixedly installed in a designated location to ensure stable signal coverage. However, uneven ground can cause the device to tilt, reducing its stability and making it more prone to tipping over when subjected to external impacts. This can affect the normal operation of the broadcasting system and cause equipment damage. Therefore, this solution proposes an anti-interference signal transmitting device for digital broadcast television wireless transmission to address the aforementioned problems. Utility Model Content

The other side of the adjusting block has a square groove, and the threaded sleeve is inserted into the square groove. The square groove and the through hole are interconnected, and a limiting member is provided at the connection between the threaded sleeve and the square groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 An anti-interference signal transmitting device for digital broadcast television wireless transmission is shown, comprising:

[0024] Digital signal transmitter 1;

[0025] Support rod 2 is located at the bottom of digital signal transmitter 1;

[0026] Adjustment component 3 includes an adjustment block 306 fixedly connected to the bottom of support rod 2, a fixing block 304 at the bottom of digital signal transmitter 1, a sliding groove 305 at the top of fixing block 304, and adjustment block 306 inserted into the sliding groove 305. A fixing member for adjusting the height of adjustment block 306 is provided at the connection between fixing block 304 and adjustment block 306. The horizontal and longitudinal cross sections of sliding groove 305 and adjustment block 306 are both triangular.

[0027] It should be noted that the digital signal transmitter 1 is a GT-5900A-500 indoor terrestrial digital television broadcasting transmitter, which has stable output power. Multiple protection mechanisms, including over-temperature, over-current, over-excitation, and standing wave ratio protection, are employed to enhance equipment stability. Stable output power reduces signal fluctuations and prevents interference from adjacent channels or a decrease in the signal-to-noise ratio at the receiver due to power drift, thereby indirectly improving anti-interference capabilities. The fixed block 304 is fixedly connected to the installation position with bolts. Both the sliding groove 305 and the adjusting block 306 are triangular in design, so that when the hypotenuse of the adjusting block 306 moves on the hypotenuse of the sliding groove 305, the height of the adjusting block 306 from the ground varies, thus achieving height adjustment. When it is necessary to adjust the height of one corner of the digital signal transmitter 1, the adjusting block 306 is first slid inside the sliding groove 305. After the adjusting block 306 slides to the required height, it is restricted by the fixing component, preventing the adjusting block 306 from moving. This completes the adjustment of all four corners of the digital signal transmitter 1, preventing the digital signal transmitter 1 from tilting.

[0028] Specifically, a threaded rod 309 is inserted and connected to one side of the fixed block 304, and a rotating block 302 is fixedly connected to one end of the threaded rod 309. A threaded sleeve 308 is threadedly fitted in the middle of the threaded rod 309. The threaded sleeve 308 is used to press the adjusting block 306. A through hole 303 is opened on one side of the adjusting block 306, and the threaded rod 309 is inserted and connected inside the through hole 303. A square groove 307 is opened on the other side of the adjusting block 306, and the threaded sleeve 308 is inserted and connected inside the square groove 307. The square groove 307 and the through hole 303 are interconnected. A limiting member 4 is provided at the connection between the threaded sleeve 308 and the square groove 307.

[0029] It should be noted that the adjusting block 306 is pressed downward by the digital signal transmitter 1, causing the inclined surface of the adjusting block 306 to fit against the inclined surface of the sliding groove 305. The side of the adjusting block 306 away from the fixed block 304 is connected to the threaded sleeve 308 through the limiting member 4. When adjusting the distance between the threaded block 308 and the fixed block 304, the height of the adjusting block 306 is adjusted by the pressing of the threaded block 308. The threaded sleeve 308 is a block with a threaded hole in the middle, and its thread is fitted in the middle of the threaded rod 309. The threaded rod 309 is used to adjust the distance between the threaded sleeve 308 and the fixed block 304.

[0030] Specifically, the horizontal longitudinal section of the threaded sleeve 308 is set to hexagon, and the square groove 307 is used to restrict the rotation of the threaded sleeve 308.

[0031] It should be noted that the front and back of the hexagonal threaded sleeve 308 are fitted with the inner walls of the front and back of the square groove 307. The square groove 307 blocks the threaded sleeve 308 from rotating inside it.

[0032] Specifically, a twisting groove 301 is provided on one side of the rotating block 302, and the horizontal longitudinal section of the twisting groove 301 is set as hexagonal.

[0033] It should be noted that the tightening groove 301 is compatible with a hex wrench. When it is necessary to rotate the rotating block 302, the hex wrench is inserted into the tightening groove 301, and the rotating block 302 is rotated by the hex wrench.

[0034] Specifically, the limiting component 4 includes limiting grooves 402 symmetrically opened on the inner walls of the front and back sides of the square groove 307, and limiting blocks 401 symmetrically fixedly connected to the front and back sides of the threaded sleeve 308, with the limiting blocks 401 inserted into the interior of the limiting grooves 402.

[0035] It should be noted that the limiting groove 402 is adapted to the limiting block 401, so that the limiting block 401 can move vertically inside the limiting groove 402. However, due to the obstruction of the limiting block 401 and the limiting groove 402, the threaded sleeve 308 cannot be moved out of the square groove 307.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
