Description

Technical Field

[0001] This utility model belongs to the field of broadcasting and television engineering technology, specifically a broadcasting and television engineering antenna bracket. Background Technology

[0002] As a modern communication medium, radio and television broadcasting uses radio waves or wired transmission networks to disseminate audiovisual content to audiences, serving functions such as information transmission, public opinion guidance, and social education. Based on differences in transmission methods, it can be divided into two main types: wireless radio and television broadcasting and cable radio and television broadcasting. In radio and television system engineering, antenna supports are key infrastructure. Their core function is to provide reliable mechanical support and precise spatial positioning for various antennas. These supports are usually installed on building roofs, dedicated iron towers, or special structures to ensure the high-efficiency transmission and reception of electromagnetic wave signals by ensuring the structural stability of the antenna.

[0003] In existing broadcasting and television technology, in order to ensure signal transmission quality and reduce environmental interference, antennas usually need to be erected in high-altitude locations such as high-rise buildings, iron towers, or mountaintops. This installation requirement makes some antenna brackets have the characteristic of being detachable for transportation. In actual construction, the brackets often need to be modularly disassembled first, and after being transported to the target height, they are then assembled and installed on site using professional assembly processes.

[0004] However, during the assembly of modular splicing antenna brackets, multiple sets of high-strength bolts are typically used to secure the joints of each segment. In actual installation, construction workers need to repeatedly tighten the bolts to achieve precise alignment and reliable fixation. This not only increases installation time but also increases the labor intensity of working at heights. Furthermore, when the bracket system is subjected to external forces such as wind loads, snow loads, or accidental impacts, significant stress concentration will occur at the splicing nodes. Long-term alternating stress may lead to safety hazards such as loose bolts, structural deformation, or even fatigue fracture at the connection points. Therefore, a new antenna bracket for broadcasting and television engineering is proposed to address the above problems. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 5 This utility model provides an antenna bracket for broadcast television engineering, including a support rod 1; a connecting rod 2 is inserted into the inner wall of the top end of the support rod 1; a base plate 7 is fixedly connected to the bottom of the support rod 1; a connecting plate 41 is slidably connected to the inner wall of the bottom end of the connecting rod 2; a spring 42 is fixedly connected to the side wall of the connecting plate 41; the other end of the spring 42 is fixedly connected to the inner wall of the bottom end of the connecting rod 2; a push block 4 is fixedly connected to the side wall of the top end of the connecting plate 41; the push block 4 is slidably connected to the side wall of the connecting rod 2 .... A limiting block 43 is connected; the limiting block 43 is slidably connected to the inner wall of the bottom end of the connecting rod 2; a limiting groove 6 is formed on the inner wall of the top end of the support rod 1; the limiting block 43 contacts the inner wall of the limiting groove 6; four sets of hinge blocks 31 are fixedly connected in a circular array on the outer wall of the top end of the support rod 1; a top plate 3 slides on the inner wall of the hinge block 31; a damping block 37 is fixedly connected to the side wall of the top of the top plate 3; the damping block 37 contacts the side wall of the connecting rod 2; during operation, when it is necessary to install the support rod 1 and the connecting rod 2, the connecting rod 2 can be... Rod 2 is inserted into the inner wall of the top end of support rod 1. Before insertion, push block 4 can be pressed. Push block 4 will move connecting plate 41, which will compress spring 42. At the same time, connecting plate 41 will move limiting block 43, so that limiting block 43 completely tightens the inner wall of the bottom end of connecting rod 2. In this way, connecting rod 2 can be smoothly inserted into the inner wall of the top end of support rod 1. After connecting rod 2 is fully inserted, push block 4 can be released. At this time, spring 42 will push spring 42 to move in the opposite direction due to its own elasticity, and limiting block 43 will also move in the opposite direction. The movement causes the limiting block 43 to insert into the inner wall of the limiting groove 6, thus completing the installation of the support rod 1 and the connecting rod 2. This eliminates the need for workers to fix them by rotating multiple sets of bolts, making the process quick and convenient. After the support rod 1 and the connecting rod 2 are installed, the multiple sets of top plates 3 will rotate, causing the damping block 37 to be tightly attached to the outer wall of the connecting rod 2. This improves the stability of the connection end between the support rod 1 and the connecting rod 2, reduces the risk of loosening at the splice node of the support rod 1 and the connecting rod 2 due to significant stress concentration, and improves practicality.

[0027] Furthermore, such as Figure 1 and Figure 3As shown, a protective shell 5 is slidably connected to the outer wall of the bottom end of the support rod 1; a handle 53 is fixedly connected to the top of the protective shell 5; a sealing ring 52 is fixedly connected to the inner wall of the bottom of the handle 53; a sealing groove 8 is formed on the outer wall of the base plate 7; the sealing ring 52 contacts the inner wall of the sealing groove 8. When working, if the base plate 7 needs to be removed from its installation position, the handle 53 can be held and pulled. The handle 53 will drive the protective shell 5 to move, and the protective shell 5 will drive the sealing ring 52 to move. The sealing ring 52 has a certain elasticity. When moving, it will slowly detach from the inner wall of the sealing groove 8 and be subjected to... The protective shell 5 is deformed by compression until it completely detaches from the base plate 7, exposing the bolts fixing the base plate 7. At this point, the worker can use tools to turn the bolts to remove the base plate 7. After the base plate 7 is reinstalled, the protective shell 5 can be pushed in the opposite direction to fit onto the outer wall of the base plate 7. During the pushing, the sealing ring 52 will be compressed and deformed until it overlaps with the sealing groove 8. At this point, the handle 53 will reset through its own elasticity and lock into the inner wall of the sealing groove 8. This improves the sealing performance of the protective shell 5 and ensures its protective effect on the bolts fixing the base plate 7.

[0028] Furthermore, such as Figure 4 As shown, a rotating rod 35 is fixedly connected through the side wall of the top plate 3; the rotating rod 35 is rotatably connected to the inner wall of the hinge block 31; a torsion spring 36 is sleeved on the outer wall of the rotating rod 35; one end of the torsion spring 36 is fixedly connected to the side wall of the top plate 3; the other end of the torsion spring 36 is fixedly connected to the inner wall of the hinge block 31. During operation, when the connecting rod 2 is inserted into the inner wall of the support rod 1, it will push the sliding plate 32 to move. The sliding plate 32 will push the top plate 3 to rotate around the center of the rotating rod 35. When the top plate 3 rotates, it will cause the torsion spring 36 to undergo torsional deformation. When the connecting rod 2 is separated from the support rod 1, the torsion spring 36 will use its own elasticity to drive the top plate 3 to rotate in the opposite direction around the center of the rotating rod 35, ensuring that the connecting rod 2 can smoothly detach from the inner wall of the support rod 1. At the same time, it also ensures that when the connecting rod 2 is inserted into the inner wall of the support rod 1, it will not be obstructed by multiple sets of damping blocks 37, thus improving practicality.

[0029] Furthermore, such as Figure 2 and Figure 4 As shown, a sliding plate 32 is slidably mounted on the inner wall of the bottom end of the top plate 3; the sliding plate 32 is slidably connected to the side wall of the top end of the support rod 1; a sliding rod 33 is rotatably connected to the side wall of the sliding plate 32; a through groove 34 is provided on the side wall of the bottom end of the top plate 3; the outer wall of the sliding rod 33 is slidably connected to the inner wall of the through groove 34. During operation, when the connecting rod 2 is inserted into the inner wall of the support rod 1, it will push the sliding plate 32 to move. At this time, the sliding plate 32 will drive the sliding rod 33 to slide on the inner wall of the through groove 34, ensuring that it can smoothly push the top plate 3 to rotate, thus improving practicality.

[0030] Furthermore, such as Figure 2 and Figure 4 As shown, the side wall of the slide plate 32 is set as an inclined surface. During operation, the inclined surface ensures that when the connecting rod 2 is inserted into the inner wall of the support rod 1, the connecting rod 2 can smoothly push the slide plate 32 to move along the inclined surface, thus improving practicality.

[0031] Furthermore, such as Figure 3 As shown, a movable block 51 is fixed to the inner wall of the top of the protective shell 5; a sliding groove 54 is provided on the outer wall of the bottom end of the support rod 1; the movable block 51 slides on the inner wall of the sliding groove 54. When the protective shell 5 is pulled, it will drive the movable block 51 to slide the inner wall of the sliding groove 54, ensuring that the protective shell 5 can move up and down stably, and ensuring that when the movable block 51 moves to the top of the sliding groove 54, it can be smoothly locked in the inner wall of the locking groove 55 to limit the protective shell 5, thus improving its practicality.

[0032] Furthermore, such as Figure 3 As shown, the bottom side wall of the support rod 1 is provided with a snap-fit ​​groove 55 at the top of the slide groove 54; the moving block 51 slides on the inner wall of the snap-fit ​​groove 55; the slide groove 54 and the snap-fit ​​groove 55 are connected. When the protective shell 5 is opened during operation, the moving block 51 can be snapped into the inner wall of the snap-fit ​​groove 55, which reduces the risk of the protective shell 5 falling and ensures that the staff can use the functional bolts to fix the base plate 7 smoothly, thus improving practicality.

[0033] Working principle: When it is necessary to install support rod 1 and connecting rod 2, the connecting rod 2 can be inserted into the inner wall of the top of support rod 1. Before insertion, push block 4 can be pressed. Push block 4 will drive connecting plate 41 to move. Connecting plate 41 will squeeze spring 42. At the same time, connecting plate 41 will drive limiting block 43 to move, so that limiting block 43 completely tightens the inner wall of the bottom of connecting rod 2. In this way, connecting rod 2 can be smoothly inserted into the inner wall of the top of support rod 1. After connecting rod 2 is fully inserted, release push block 4. At this time, spring 42 will push spring 42 to move in the opposite direction through its own elasticity. Limiting block 43 will also move in the opposite direction, so that limiting block 43 is inserted into the inner wall of limiting groove 6. In this way, support rod 1 and connecting rod 2 are installed. There is no need for workers to fix them by rotating multiple sets of bolts. It is quick and convenient. After the support rod 1 and connecting rod 2 are installed.

[0034] During the process of inserting the connecting rod 2 into the support rod 1, the connecting rod 2 will move along the inclined surface of the multiple sets of sliding plates 32. The sliding plates 32 will drive the sliding rod 33 to slide on the inner wall of the through groove 34, and cause the top plate 3 to rotate around the center of the rotating rod 35. In this way, the multiple sets of top plates 3 will rotate, so that the damping block 37 is tightly attached to the outer wall of the connecting rod 2. This can improve the stability of the connection end between the support rod 1 and the connecting rod 2, reduce the risk of loosening at the splicing node of the support rod 1 and the connecting rod 2 due to significant stress concentration, and improve practicality.

[0035] When the base plate 7 needs to be removed from its installation position, the handle 53 can be held and pulled. The handle 53 will move the protective shell 5, which in turn will move the sealing ring 52. The sealing ring 52 has a certain elasticity. During the movement, it will slowly detach from the inner wall of the sealing groove 8 and be deformed by compression until the protective shell 5 is completely detached from the base plate 7, exposing the bolts fixing the base plate 7. At this point, the worker can use tools to turn the bolts to remove the base plate 7. After the base plate 7 is reinstalled, the protective shell 5 can be pushed in the opposite direction to fit onto the outer wall of the base plate 7. During the push, the sealing ring 52 will be deformed by compression until it overlaps with the sealing groove 8. At this point, the handle 53 will reset through its own elasticity and lock into the inner wall of the sealing groove 8. This improves the sealing performance of the protective shell 5 and ensures its protective effect on the bolts fixing the base plate 7.

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.
