[0002] In a color television system, the video signal (image signal), composite synchronization signal, and composite blanking signal are combined to form the full television signal, which is the signal transmitted by broadcast television. After the receiver demodulates the full television signal, the synchronization signal can be separated using a limiting method. Then, the horizontal synchronization signal and the vertical synchronization signal are obtained separately using differentiating and integrating circuits to control the generation of the scanning current.
[0003] During daily use and carrying, the internal components of the device may become loose due to vibration, collision, or other reasons. In order to ensure that the broadcast television wireless receiver can be used normally, users usually need to perform periodic checks on the inside of the device.
[0004] Existing devices typically use several threads for installation and connection. When users need to inspect the inside of the device, they need to go through cumbersome steps and spend a lot of time to remove the protective plate. This not only causes the device to be unusable for a long time, affecting the reception and playback of broadcast television signals and causing inconvenience to users, but also, during the process of removing the protective plate, the use of tools for twisting and other operations may accidentally damage other components of the device. Therefore, we propose a stable broadcast television wireless receiver to solve the above problems. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] Example 1, such as Figure 1-7 As shown, a stable broadcast television wireless receiving device includes a housing 1, a protective cover 11 slidably connected to the inner wall of the top of the housing 1, storage slots 12 are provided at the left and right ends of the housing 1, a ventilation plate 13 is fixedly connected to the inner wall of the back of the housing 1, a disassembly component 2 is provided at the top of the housing 1, and storage components 3 are provided inside the two storage slots 12.
[0028] Specifically, to achieve the goal of quickly installing and removing the protective cover, please refer to... Figure 3 and Figure 4 In this embodiment, the disassembly assembly 2 includes two fixing rods 21. The two fixing rods 21 are arranged symmetrically about the center of the box 1. The bottom of the fixing rods 21 is fixedly connected to the top of the box 1. A rotating frame 22 is rotatably connected to the outer surface of the fixing rods 21. The bottom of the rotating frame 22 is in contact with the top of the protective cover 11.
[0029] Further reading Figure 3 In this embodiment, a threaded rod 23 is threadedly connected to the inner wall of the rotating frame 22, and a rotating block 231 is fixedly connected to the top of the threaded rod 23. A sliding groove is provided on the left side of the rotating frame 22, and a connecting rod 233 is slidably connected to the inner wall of the sliding groove. An insert block 232 is rotatably connected to the bottom outer surface of the threaded rod 23, and the end of the insert block 232 away from the center of the box 1 is fixedly connected to the end of the connecting rod 233 near the center of the box 1.
[0030] Further reading Figure 3 In this embodiment, the top of the protective cover 11 has two slots, and the bottom outer surface of the insert block 232 is engaged with the inner wall of the slot on the same side.
[0031] During implementation, firstly, rotating the rotating block 231 counterclockwise causes the threaded rod 23 to rotate in the inner wall of the rotating frame 22. As the threaded rod 23 rotates, it causes the insert block 232 to move upward. When the insert block 232 moves, it causes the connecting rod 233 to slide in the inner wall of the sliding groove on the left side of the rotating frame 22. After the insert block 232 moves upward a certain distance, the bottom outer surface of the insert block 232 will separate from the inner wall of the slot opened at the top of the protective cover 11. After the insert block 232 is moved, rotating the rotating frame 22 will separate it from the top of the protective cover 11. By rotating the two rotating blocks 231, the restriction on the protective cover 11 can be released.
[0032] Further reading Figure 5 In this embodiment, a second fixing rod 24 is fixedly connected to the inner wall of the box 1, and a sliding frame 241 is slidably connected to the outer surface of the second fixing rod 24. A first spring 242 is sleeved on the outer surface of the second fixing rod 24. The front of the first spring 242 is fixedly connected to the back of the sliding frame 241, and the back of the first spring 242 is fixedly connected to the inner wall of the box 1. A fixing block 243 is fixedly connected to the bottom of the protective cover 11, and the back of the fixing block 243 is in contact with the front of the sliding frame 241.
[0033] During implementation, after the restriction is lifted, the protective cover 11 will slide forward under the elastic force of spring 242, making it easier and faster for staff to remove the protective cover 11. This not only significantly shortens maintenance time and allows for quick restoration of equipment operation and reduced downtime, improving the user experience, but also avoids damage to other parts of the equipment caused by using tools to remove screws.
[0034] Example 2: This example adds a storage component based on Example 1.
[0035] Specifically, to achieve the goal of storing the telescopic antenna, please refer to... Figure 6 In this embodiment, the two storage components 3 are arranged symmetrically with the center of the box 1 as the left and right. The storage component 3 includes a slider 31. The storage groove 12 has a second sliding groove on the side near the center of the box 1. The inner wall of the second sliding groove is slidably connected to the outer surface of the slider 31 on the side near the center of the box 1.
[0036] Further reading Figure 6 In this embodiment, a round rod 32 is fixedly connected to one end of the slider 31 away from the center of the housing 1. A spring 33 is sleeved on the outer surface of the round rod 32, and a connecting frame 35 is slidably connected to the outer surface of the round rod 32.
[0037] Further reading Figure 6 In this embodiment, the connecting frame 35 contacts two limiting plates 34 near the housing 1. The ends of the two limiting plates 34 that are far apart from each other are fixedly connected to the inner wall of the storage groove 12 on the same side. A pull rod antenna 36 is fixedly connected to the top of the connecting frame 35. The end of the second spring 33 that is far away from the center of the housing 1 is fixedly connected to the end of the connecting frame 35 that is close to the center of the housing 1. The end of the second spring 33 that is close to the center of the housing 1 is fixedly connected to the end of the slider 31 that is far away from the center of the housing 1.
[0038] During implementation, when the device is not in use or being carried, the telescopic antenna 36 is first retracted. After retraction, the slider 31 is pushed to slide forward in the inner wall of the corresponding slide groove. When the slider 31 reaches the end point of the inner wall of the slide groove, the connecting frame 35 is rotated so that the end near the center of the housing 1 is separated from the surface of the two limiting plates 34. After rotation, the deformed spring 33 will pull the connecting frame 35 towards the center of the housing 1 due to the elastic force. When the connecting frame 35 moves, it will drive the telescopic antenna 36 to move so that it can be stored in the corresponding storage slot 12. This not only avoids friction and collision between the telescopic antenna 36 and other items during daily placement or carrying, reducing the risk of breakage and deformation and ensuring stable performance, but also makes the overall size of the device more regular and occupies less space after the telescopic antenna 36 is stored.
[0039] The working principle of this utility model is as follows: When it is necessary to inspect the inside of the box 1, firstly, rotate the rotating block 231 counterclockwise to drive the threaded rod 23 to rotate in the inner wall of the rotating frame 22. While the threaded rod 23 rotates, it will drive the insert block 232 to move upward. When the insert block 232 moves, it will drive the connecting rod 233 to slide in the inner wall of the groove on the left side of the rotating frame 22. After the insert block 232 moves upward a certain distance, the outer surface of the bottom of the insert block 232 will separate from the inner wall of the slot opened at the top of the protective cover 11. After the insert block 232 is moved, rotate the rotating frame 22 to separate it from the top of the protective cover 11. By rotating the two rotating blocks 231, the restriction on the protective cover 11 can be released. After the restriction is released, the protective cover 11 will slide forward under the elastic force of the spring 242, making it easier and faster for the staff to remove the protective cover 11. Removing the cover not only significantly shortens maintenance time and allows for quick restoration of equipment operation, reducing downtime and improving user experience, but also avoids damage to other parts of the equipment caused by using tools to remove screws. After inspection, the protective cover 11 is pushed to slide backward in the inner wall of the top of the housing 1. During the sliding process, the protective cover 11 will cause the fixing block 243 to come into contact with the sliding frame 241 and push it to slide backward on the outer surface of the fixing rod 24. When the sliding frame 241 slides, it will compress the spring 242, causing it to deform, thus providing power for the next removal of the protective cover 11. After the protective cover 11 is installed, the bottom of the insert block 232 is re-inserted into the inner wall of the slot at the top of the protective cover 11 by rotating the rotating block 231 clockwise, thus restricting the protective cover 11.
[0040] When the device is not in use or being carried, first retract the telescopic antenna 36. After retraction, push the slider 31 to slide forward in the inner wall of the corresponding groove. When the slider 31 reaches the end point of the inner wall of the groove, rotate the connecting frame 35 so that its end near the center of the housing 1 separates from the surfaces of the two limiting plates 34. After rotation, the deformed spring 33 will pull the connecting frame 35 towards the center of the housing 1 due to its elasticity. When the connecting frame 35 moves, it will drive the telescopic antenna 36 to move so that it can be stored in the corresponding storage slot 12. This not only prevents the telescopic antenna 36 from being damaged by other objects during daily storage or carrying. The device reduces the risk of breakage and deformation due to friction and collision, ensuring stable performance. Moreover, after the telescopic antenna 36 is stored, the overall size of the device is more regular and occupies less space. When the device is in use, the connecting frame 35 is pulled away from the center of the box 1. When the connecting frame 35 moves, it will pull out the second spring 33 and cause it to deform. After the connecting frame 35 moves to a certain position, it is rotated so that the telescopic antenna 36 can be perpendicular to the top of the box 1. After the rotation is completed, the deformed second spring 33 will pull the end of the connecting frame 35 near the center of the box 1 to make close contact with the surface of the two limiting plates 34 due to the elastic force.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
