Description

Technical Field

[0001] This utility model relates to the field of broadcasting and television engineering technology, and specifically to a wireless coverage transmission box for broadcasting and television engineering. Background Technology

[0002] Broadcast and television engineering is a comprehensive engineering and technical field involving the transmission, reception, processing, and broadcasting of broadcast and television signals. It covers the entire process from program production to signal transmission, reception, and terminal display. The wireless coverage transmission box is a device used in broadcast and television engineering, mainly for the transmission and coverage of wireless signals. It is usually installed on utility poles or other supporting structures to transmit broadcast and television signals to receiving equipment wirelessly to achieve wide-area signal coverage. The wireless coverage transmission box plays an important role in broadcast and television engineering and is a key device for realizing wireless signal transmission and coverage.

[0003] In existing technologies, in village-to-village broadcasting and television projects, wireless coverage transmission boxes are typically installed on utility poles in the middle of villages to receive and transmit signals. Most of these installations involve installing a flange plate on the utility pole that corresponds to the size of the wireless coverage transmission box's base. Holes are drilled in the utility pole according to the flange plate's hole positions, with the hole diameter and depth matching the fixing bolts. The flange plate is then aligned with the fixing points on the utility pole and secured with bolts and nuts. Finally, the wireless coverage transmission box is tightly fixed to the flange plate with screws. Although this installation method provides structural stability, the installation process is time-consuming, requires numerous tools, is cumbersome, and the disassembly of the wireless coverage transmission box is slow.

[0004] Therefore, a wireless coverage transmission box for broadcast television engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wireless coverage transmission box for broadcasting and television engineering in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A wireless coverage transmission box for broadcast television engineering includes an L-shaped plate and a wireless coverage transmission box body. The surface of the L-shaped plate is provided with reinforcing ribs and a shielding canopy. A positioning groove is formed on the surface of the L-shaped plate, and the wireless coverage transmission box body is slidably disposed on the inner wall of the positioning groove. A first fixing mechanism for clamping and fixing to a utility pole is provided on the surface of the L-shaped plate, and the number of the first fixing mechanism is set to two sets. A second fixing mechanism for clamping and fixing the wireless coverage transmission box body is provided on the L-shaped plate.

[0008] Furthermore, the fixing mechanism includes a fixing arc plate, which is fixedly installed on the surface of the L-shaped plate. Two bolts are slidably installed on the fixing arc plate, and mounting arc plates are slidably installed on the outer walls of the two bolts. Spring washers are slidably installed on the outer walls of the two bolts, and nuts are threaded onto the outer walls of the two bolts. Friction pads are fixedly installed on the surfaces of both the fixing arc plate and the mounting arc plate.

[0009] Furthermore, the second fixing mechanism includes two fixing frames, which are fixedly installed at the bottom of the L-shaped plate. A bidirectional screw is rotatably installed inside the left fixing frame, and a cylinder is fixedly installed inside the right fixing frame. Two adjusting rods are threaded on the outer wall of the bidirectional screw, and the adjusting rods are slidably installed on the cylinder and the L-shaped plate. The front end of the bidirectional screw extends outside the fixing frame, and a knob is fixedly installed on the surface of the extended end of the bidirectional screw.

[0010] Furthermore, multiple fixed posts are slidably mounted on both adjusting rods, buffer springs are sleeved on the outer walls of the multiple fixed posts, two fixed rods are fixedly mounted on the surface of the multiple fixed posts, two connecting rods are fixedly mounted on the surface of the multiple fixed posts, and friction pads are fixedly mounted on the surface of the two fixed rods.

[0011] Furthermore, grooves are provided on the surfaces of both friction pads, and both friction pads are made of rubber.

[0012] Furthermore, the number of reinforcing ribs is set to two, which are symmetrically distributed.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the arrangement of fixing mechanism one, fixing mechanism two, and a shielding canopy, allows for easy installation and fixation of the wireless coverage transmission box body on the utility pole. Fixing mechanism one secures the L-shaped plate to the pole, and then the wireless coverage transmission box body is placed in the positioning groove. Fixing mechanism two clamps and fixes the wireless coverage transmission box body. The reinforcing ribs increase the load-bearing capacity of the L-shaped plate, and the shielding canopy blocks sunlight from directly hitting the wireless coverage transmission box body, preventing direct sunlight from causing the internal temperature of the wireless coverage transmission box body to rise, potentially affecting the normal operation of the equipment or even causing overheating failure.

[0025] like Figure 1 As shown, a wireless coverage transmission box for broadcast television engineering includes an L-shaped plate 1 and a wireless coverage transmission box body 4. A reinforcing rib 2 is provided on the surface of the L-shaped plate 1, and a shielding canopy 3 is provided on the surface of the L-shaped plate 1. A positioning groove is formed on the surface of the L-shaped plate 1, and the wireless coverage transmission box body 4 is slidably disposed on the inner wall of the positioning groove. A fixing mechanism 1 5 for clamping and fixing to a utility pole is provided on the surface of the L-shaped plate 1, and two sets of fixing mechanisms 1 5 are provided. A second fixing mechanism 6 for clamping and fixing the wireless coverage transmission box body 4 is also provided on the L-shaped plate 1. In this embodiment, during use, the L-shaped plate 1 is fixed to the utility pole by the fixing mechanism 1 5. The wireless coverage transmission box body 4 is placed on the utility pole and then placed in the positioning groove. The wireless coverage transmission box body 4 is clamped and fixed by the fixing mechanism 2 6. The setting of the reinforcing rib plate 2 increases the load-bearing capacity of the L-shaped plate 1, and the setting of the shielding canopy 3 can block sunlight from the wireless coverage transmission box body 4, preventing sunlight from directly shining on the wireless coverage transmission box body 4 and causing the internal temperature of the wireless coverage transmission box body 4 to rise, which may affect the normal operation of the equipment or even cause overheating failure. Thus, it is easy to install and fix the wireless coverage transmission box body 4 on the utility pole, and the wireless coverage transmission box body 4 can be quickly disassembled. The operation is simple and the practicality is strong.

[0026] like Figure 1-2As shown, the fixing mechanism 5 includes a fixing arc plate 501, which is fixedly installed on the surface of the L-shaped plate 1. Two bolts 504 are slidably installed on the fixing arc plate 501. An mounting arc plate 502 is slidably installed on the outer wall of the two bolts 504. A spring washer 505 is slidably installed on the outer wall of each of the two bolts 504. A nut 506 is threaded onto the outer wall of each of the two bolts 504. Friction pads 503 are fixedly installed on the surfaces of both the fixing arc plate 501 and the mounting arc plate 502. In this embodiment, the friction pads 503 on the fixing arc plate 501 are brought into contact with the surface of the utility pole, and then the friction pads 503 on the mounting arc plate 502 are brought into contact with the power pole. The pole surfaces are in contact, and then bolts 504 pass through the fixing arc plate 501 and the mounting arc plate 502. A spring washer 505 is fitted over the bolt 504, and then the nut 506 is screwed onto the bolt 504, so that the spring washer 505 and the fixing arc plate 501 are tightly fitted together. The two friction pads 503 are tightly fitted with the utility pole. The two friction pads 503 can enhance the frictional resistance with the utility pole and improve the stability of the fixation. The spring washer 505, through its elastic deformation, generates a continuous preload, which can maintain the tightness of the connection under vibration or dynamic load environment and prevent the bolt 504 or nut 506 from loosening. Therefore, the L-shaped plate 1 is stably fixed to the utility pole.

[0027] like Figure 1 , Figure 3-4 As shown, the fixing mechanism 6 includes two fixing frames 601, which are fixedly installed at the bottom of the L-shaped plate 1. A bidirectional screw 602 is rotatably installed inside the left fixing frame 601, and a cylinder 603 is fixedly installed inside the right fixing frame 601. Two adjusting rods 604 are threadedly installed on the outer wall of the bidirectional screw 602, and the adjusting rods 604 are slidably installed on the cylinder 603 and the L-shaped plate 1. The front end of the bidirectional screw 602 extends outside the fixing frame 601, and a knob 610 is fixedly installed on the surface of the extended end of the bidirectional screw 602. In this embodiment, by rotating the knob 610, the bidirectional screw 602 is driven to rotate, causing the two adjusting rods 604 to move closer to each other or further away from each other, thereby adjusting the distance between the two adjusting rods 604.

[0028] like Figure 3-4As shown, multiple fixing posts 605 are slidably mounted on both adjusting rods 604. Each fixing post 605 has a buffer spring 606 fitted onto its outer wall. Two fixing rods 607 are fixedly mounted on the surface of each fixing post 605, and two connecting rods 609 are fixedly mounted on the surface of each fixing post 605. Friction pads 608 are fixedly mounted on the surface of each fixing rod 607. In this embodiment, when the two adjusting rods 604 move closer to each other, the two friction pads 608 fit tightly against both sides of the wireless coverage transmission box body 4, causing the multiple fixing posts 605 to slide on the two adjusting rods 604, compressing the multiple buffer springs 606. This provides buffering during clamping, preventing damage to the wireless coverage transmission box body 4 due to excessive clamping force, and enhancing the fastening effect.

[0029] like Figure 2-4 As shown, grooves are provided on the surfaces of both friction pad 503 and friction pad 608. Both friction pad 503 and friction pad 608 are made of rubber. In this embodiment, the grooves enhance the contact area, and the high elasticity and good coefficient of friction of rubber enhance the stability of the fixation.

[0030] like Figure 1 As shown, the number of reinforcing ribs 2 is set to two, which are symmetrically distributed. In this embodiment, the load-bearing capacity of the L-shaped plate 1 is improved by setting the number of reinforcing ribs 2.

[0031] In summary, during use, the L-shaped plate 1 is fixed to the utility pole by fixing mechanism 5, and then the wireless coverage transmission box body 4 is placed in the positioning groove. Fixing mechanism 6 clamps and fixes the wireless coverage transmission box body 4. The reinforcing rib 2 increases the load-bearing capacity of the L-shaped plate 1, and the canopy 3 blocks sunlight from directly hitting the wireless coverage transmission box body 4, preventing direct sunlight from rising the internal temperature of the body 4, which could affect the normal operation of the equipment or even cause overheating. This facilitates the wireless coverage transmission box body's operation. The main body 4 of the wireless coverage transmission box is installed and fixed on the utility pole, and can be quickly disassembled individually. It is simple to operate and highly practical. The process involves contacting the friction pad 503 on the fixed arc plate 501 with the surface of the utility pole, then contacting the friction pad 503 on the mounting arc plate 502 with the surface of the utility pole. A bolt 504 passes through the fixed arc plate 501 and the mounting arc plate 502. A spring washer 505 is fitted over the bolt 504, and then a nut 506 is screwed onto the bolt 504, ensuring a tight fit between the spring washer 505 and the fixed arc plate 501. The two friction pads... The first friction pad 503 fits tightly against the utility pole. The two friction pads 503 enhance frictional resistance with the pole, improving stability. The spring washer 505, through its elastic deformation, generates a continuous preload, maintaining the connection's tightness under vibration or dynamic load conditions and preventing the bolt 504 or nut 506 from loosening. Therefore, the L-shaped plate 1 is stably fixed to the utility pole. Rotating the knob 610 drives the bidirectional screw 602 to rotate, causing the two adjusting rods 604 to move closer or further apart, thus adjusting the distance between the two adjusting rods 604. When the two adjusting rods 604 move closer to each other, the two friction pads 608 fit tightly against both sides of the wireless coverage transmission box body 4, and the multiple fixing posts 605 slide on the two adjusting rods 604, compressing the multiple buffer springs 606, thereby providing buffering during the clamping process, preventing damage to the wireless coverage transmission box body 4 due to excessive clamping force, and enhancing the fastening effect. The groove setting increases the contact area, and the rubber has high elasticity and a good coefficient of friction, enhancing the stability of the fixation. The number of reinforcing ribs 2 increases the load-bearing capacity of the L-shaped plate 1.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
