Description

Technical Field

[0001] This utility model relates to the field of broadcasting and television engineering technology, and in particular to antenna brackets for broadcasting and television engineering. Background Technology

[0002] After natural disasters such as earthquakes and floods disrupt traditional communications, engineering teams need to quickly deploy temporary broadcast and television base stations. By precisely fixing the transmitting antenna on open, high ground using antenna brackets, and utilizing the height adjustment and angle calibration functions of the brackets, emergency broadcast signals can cover the disaster-stricken areas, ensuring the timely transmission of disaster relief instructions and public information. The antenna brackets in broadcast and television engineering support the core mechanical structure of the transmitting or receiving antennas for broadcast and television signals. Through stable support, flexible angle adjustment, and reliable fixing, they ensure that the antennas can efficiently capture or transmit signals in complex environments.

[0003] In existing technologies, antenna supports for broadcast television engineering typically consist of a base, a load-bearing column, and an angle adjustment mechanism. The base provides stable support through a rigid connection to the ground. The load-bearing column bears the vertical load of the antenna and adjusts its height through a telescopic structure. The angle adjustment mechanism often uses manual bolts or gear transmission, changing the antenna's elevation and azimuth angles by rotating the adjustment rod, thus aligning the antenna with the signal source or the target area to be covered. The fixing components rigidly connect the antenna to the support using bolts, clips, etc., to prevent positional displacement caused by external forces, ultimately achieving stable signal reception or transmission.

[0004] In existing technologies, some antenna brackets are constructed using heavy-duty welded metal structures to ensure load-bearing strength during transportation and handling. This results in concentrated weight and a lack of modular design, requiring large hoisting equipment or multiple personnel for repeated handling during transport. This makes them unsuitable for rugged terrain in emergency scenarios where vehicles cannot directly access the area. This not only increases labor costs but also makes the components prone to deformation due to collisions, further reducing on-site assembly efficiency and seriously affecting the progress of emergency deployment or engineering construction. In response to the above problems, a new antenna bracket for broadcast television engineering is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an antenna bracket for broadcasting and television engineering, which aims to improve the problem of insufficient handling efficiency of some antenna brackets during transportation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A broadcast television engineering antenna bracket includes a base plate, with pulleys fixedly connected to the bottom of the base plate. Multiple switching mechanisms are provided at the bottom of the base plate. A support mechanism is provided outside the base plate. A telescopic rod is provided inside the support mechanism. An adjustment mechanism is provided outside the telescopic rod. A receiving antenna is fixedly connected to the outside of the adjustment mechanism. The switching mechanism includes multiple connecting columns, the tops of which are fixedly connected to the bottom of the base plate. A supporting sliding column is slidably connected to the inner side of each connecting column. A transmission connecting plate is rotatably connected inside the supporting sliding column. A telescopic assembly is provided inside each connecting column, and two linkage plates are fixedly connected to the outside of the telescopic assembly.

[0008] As a further description of the above technical solution:

[0009] The adjustment mechanism includes a support block, the bottom of which is fixedly connected to the top of the telescopic rod. Multiple cylinders are provided on the outside of the telescopic rod, and the driving ends of the multiple cylinders are fixedly connected to limit rings. Limit posts are fixedly connected to the outside of the support block.

[0010] As a further description of the above technical solution:

[0011] The two linkage plates are rotatably connected to the outside of the transmission connecting plate, and spring-loaded pins are fixedly connected to the outside of the two linkage plates.

[0012] As a further description of the above technical solution:

[0013] The telescopic assembly includes a compression spring, the compression spring being externally fixedly connected to the interior of the two linkage plates, and the compression spring being externally rotatably connected to the interior of the first connecting post.

[0014] As a further description of the above technical solution:

[0015] The compression spring is fitted with a connecting post 2, and the compression spring is fixedly connected to the outside of the transmission connecting plate.

[0016] As a further description of the above technical solution:

[0017] The limiting post is rotatably connected to a rotating post inside, and a connecting ball is fixedly connected to the outside of the rotating post. The limiting ring has an annular groove inside, and the connecting ball is slidably connected to the inside of the limiting ring. The rotating post is fixedly connected to the outside of the receiving antenna.

[0018] As a further description of the above technical solution:

[0019] The support mechanism includes a support column, the bottom of which is fixedly connected to the top of the base plate. The inside of the support column is slidably connected to the outside of the telescopic rod. A fixing ring is fixedly connected to the outside of the support column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the antenna support for a broadcasting and television project needs to be moved, the pulley contacts the ground, and pushing or pulling the base plate can move the entire antenna support to the target position. After arrival, manual pressing with feet causes the transmission connecting plate to move and rotate with the supporting sliding column, linking the two side linkage plates. The compression spring and connecting column 2 play an elastic support and limiting role, allowing the supporting sliding column to be firmly pressed against the ground. Multiple switching mechanisms work together to replace the pulley bearing the weight, firmly fixing the support to the ground, effectively avoiding the risk of displacement caused by wind and the weight of the equipment, improving the flexibility and stability of antenna system installation and relocation in broadcasting and television projects, and laying a solid foundation for signal reception and transmission.

[0024] 2. In this utility model, when adjusting the pitch angle, the cylinder pushes the limiting ring to move axially along the telescopic rod. The internal annular groove drives the connecting ball and the rotating column to move in tandem. With the help of the fulcrum of the limiting column, the pitch angle of the receiving antenna can be easily changed. The ingenious combination of the mechanical structure makes the angle adjustment precise and stable. When adjusting the azimuth angle, the antenna can be manually rotated to drive the rotating column and the connecting ball to slide in the annular groove. No complicated electrical control is required, and the operation is convenient and flexible. This ensures the stability and adaptability of broadcast and television signal reception and provides reliable support for signal capture in complex environments in engineering projects.

Detailed Implementation

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a broadcast television engineering antenna bracket, including a base plate 1, which is used to fix and support all upper structural components. A pulley 2 is fixedly connected to the bottom of the base plate 1, allowing for flexible movement of the bracket and facilitating transfer between different working positions. Multiple switching mechanisms 3 are provided at the bottom of the base plate 1, enabling switching between the moving and fixed states of the bracket to ensure its stability during operation. A support mechanism 4 is provided outside the base plate 1, and a telescopic rod 5 is provided inside the support mechanism 4. The support mechanism 4 provides vertical support and enhanced stability for the telescopic rod 5 and the upper structure. The telescopic rod 5 adjusts the height of the receiving antenna 7 by telescoping, adapting to different signal reception requirements. An adjustment mechanism 6 is provided outside the telescopic rod 5, and the receiving antenna 7 is fixedly connected to the outside of the adjustment mechanism 6. The adjustment mechanism 6 is used to adjust the elevation and azimuth angles of the receiving antenna 7 to ensure signal reception accuracy. The receiving antenna 7 is a core signal receiving component used to capture broadcast television signals.

[0034] The switching mechanism 3 includes multiple connecting columns 31, which serve as the fixed frame of the switching mechanism 3. The tops of the multiple connecting columns 31 are fixedly connected to the bottom of the base plate 1. A supporting sliding column 34 is slidably connected to the inner side of the connecting column 31. The supporting sliding column 34 can slide up and down to contact or detach from the ground. A transmission connecting plate 32 is rotatably connected inside the supporting sliding column 34. The transmission connecting plate 32 transmits external force to drive the supporting sliding column 34 to move, thereby achieving state switching. A telescopic component 35 is provided inside the connecting column 31. The telescopic component 35 provides elastic support and reset force to ensure the stable operation of the supporting sliding column 34. Two linkage plates 33 are fixedly connected to the outside of the telescopic component 35. The two linkage plates 33 are rotatably connected to the outside of the transmission connecting plate 32. The linkage plates 33 are used to transmit the force of the telescopic component 35 to the transmission connecting plate 32 to achieve synchronous linkage. A spring-loaded column 36 is fixedly connected to the outside of the two linkage plates 33. The spring-loaded column 36 assists the linkage plates 33 in resetting after being subjected to force, ensuring the reliability of the switching mechanism 3 in cyclic operation.

[0035] The telescopic assembly 35 includes a compression spring 351, which provides elastic force to buffer and reset the sliding column 34. The compression spring 351 is externally fixedly connected to the inside of the two linkage plates 33. The compression spring 351 is externally rotatably connected to the inside of the first connecting column 31. The compression spring 351 is externally sleeved with a second connecting column 352, which is used to protect the compression spring 351 and limit its deformation direction, thereby enhancing structural stability. The compression spring 351 is externally fixedly connected to the outside of the transmission connecting plate 32.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The adjustment mechanism 6 includes a support block 61, the bottom of which is fixedly connected to the top of the telescopic rod 5. Multiple cylinders 62 are provided on the outside of the telescopic rod 5. The driving end of the multiple cylinders 62 is fixedly connected to a limit ring 66. The limit ring 66 moves to drive the connecting ball 63 to move, transmitting the adjustment force. The cylinders 62 provide power to drive the limit ring 66 to move, thereby realizing the pitch angle adjustment. The support block 61 is fixedly connected to a limit post 65.

[0037] The limiting post 65 is rotatably connected to the rotating post 64. The limiting post 65 provides a fulcrum for the rotating post 64 to ensure the stability of angle adjustment. The rotating post 64 is fixedly connected to the outside of the rotating post 64. The rotating post 64 is used to connect the receiving antenna 7 and the connecting post 63 to transmit the angle adjustment action. The limiting ring 66 has an annular groove inside. The annular groove provides a sliding track for the connecting post 63 to limit the direction of movement. The connecting post 63 is slidably connected to the inside of the limiting ring 66. The connecting post 63 slides in the annular groove to realize multi-angle adjustment transmission. The rotating post 64 is fixedly connected to the outside of the receiving antenna 7.

[0038] The support mechanism 4 includes a support column 41, the bottom of which is fixedly connected to the top of the base plate 1. The inside of the support column 41 is slidably connected to the outside of the telescopic rod 5. A fixing ring 44 is fixedly connected to the outside of the support column 41. The support column 41 is the main support frame, which is fitted with the telescopic rod 5 and bears the upper load. A support diagonal rod 45 is rotatably connected to the outside of the fixing ring 44. The fixing ring 44 provides a rotation fulcrum for the support diagonal rod 45, which enhances the support stability. The support diagonal rod 45 forms a triangular stable structure to distribute the load borne by the support column 41.

[0039] The other end of the support rod 45 is slidably connected to the outside of the base plate 1. The support column 41 is slidably connected to the outside of the support ring 42. The support ring 42 is rotatably connected to the outside of the connecting rod 43. The support ring 42 changes the angle of the connecting rod 43 by sliding, thereby adjusting the support force of the support rod 45. The other end of the connecting rod 43 is rotatably connected to the outside of the support rod 45. The connecting rod 43 is used to connect the support ring 42 and the support rod 45 and transmit the adjustment action of the support ring 42.

[0040] Working principle: When the antenna support for broadcasting and television engineering needs to be moved, the pulley 2 contacts the ground and pushes or pulls the base plate 1, which can move the entire antenna support to the target position. After reaching the position, the operator presses down with their foot to make the transmission connecting plate 32 move and rotate with the support sliding column 34, which drives the linkage plates 33 on both sides to move together. At the same time, the compression spring 351 and the connecting column 352 play an elastic support and limit role, so that the support sliding column 34 is firmly pressed against the ground. The rebound column 36 assists the linkage plate 33 to return to its original position, ensuring that the structure can be reliably locked. Multiple sets of switching mechanisms 3 work together to replace the pulley 2 to bear the weight and firmly fix the support to the ground, preventing it from being blown by the wind or shifting due to its own weight.

[0041] The support column 41 is the main frame, vertically fixed on the base plate 1, and fits the telescopic rod 5, guiding its direction and providing basic support. The sliding support ring 42 drives the support inclined rod 45 through the connecting rod 43, changing its tilt angle. Combined with the position of the support ring 42, the stability of the support column 41 is enhanced, which can adapt to different terrains. The height of the telescopic rod 5 is adjusted by controlling the sliding inside the support column 41, changing the height of the top of the telescopic rod 5, and thus adjusting the vertical position of the receiving antenna 7.

[0042] When adjusting the pitch angle, cylinder 62 pushes the limiting ring 66 to move axially along the telescopic rod 5. When the limiting ring 66 moves, the internal annular groove causes the connecting ball 63 to shift. Since the connecting ball 63 and the rotating column 64 are fixed, the rotating column 64 will rotate around the limiting column 65, ultimately causing the receiving antenna 7 to change the pitch angle. When adjusting the azimuth angle, the receiving antenna 7 is manually rotated, causing the rotating column 64 and the connecting ball 63 to slide in the internal annular groove of the limiting ring 66, allowing the receiving antenna 7 to be aligned with signal sources in different directions.

[0043] 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.
