Description

Technical Field

[0001] This utility model relates to the field of cable fixing and management technology, and in particular to a quick cable fixing device for broadcasting and television engineering. Background Technology

[0002] The main structure of the cable quick-fixing device includes a base, clamping components, adjustment mechanism, and locking unit. The base provides the installation support foundation for the whole. The clamping components are in close contact with the cable through arc-shaped clamps or elastic buckles. The adjustment mechanism can flexibly adjust the clamping force. The locking unit achieves a stable lock after adjustment, ensuring that the cable remains in a stable position after installation. It meets the needs of quick cable fixing during construction and is suitable for studio cabling, outdoor broadcast van wiring, and cable fixing scenarios for broadcast television signal towers.

[0003] The cable fastening device for broadcasting and television engineering is fixed to the installation surface by a base to lay a support foundation. The cable is placed between the arc-shaped clamps or elastic buckles of the clamping component. The clamping force is adjusted by the adjustment mechanism such as knobs and springs to make the cable fit tightly against the fixing component. After adjustment, the locking unit activates the locking function to maintain the current state through mechanical locking or friction locking, so as to achieve fast and stable fixing of the cable.

[0004] In some existing technologies, cable quick-fixing devices have shortcomings when dealing with cables of different diameters or a small number of cables. Some devices have fixed clamping ring sizes, making it difficult to adapt to thin cables. Excessive gaps cause cables to wobble and rub against each other. In scenarios where single or small numbers of cables are fixed, there is a lack of targeted cable management design, and the device cannot constrain the cable's direction, which can easily cause the cables to run randomly within the device and rub against each other, affecting the cable's lifespan and signal transmission stability. Therefore, a cable quick-fixing device for broadcast and television engineering is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a quick-fixing device for cables used in broadcasting and television engineering, which aims to improve the problem that some existing devices easily cause cables to run randomly within the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A quick-fixing device for cables used in broadcasting and television engineering includes a support beam, a fixing mechanism fixedly connected to the front side of the support beam, a modular installation mechanism fixedly connected to the rear side of the support beam, and hose clamps fixedly connected to both the left and right sides of the modular installation mechanism. The fixing mechanism includes a cable bundle, a sealing block is slidably connected inside the cable bundle, a push rod is fixedly connected to the front side of the sealing block, a fixing ring is fixedly connected to the right side of the cable bundle, and a cable fixing assembly is rotatably connected inside the fixing ring. As a further description of the above technical solution: The cable fixing assembly includes a claw rod one, a claw rod two rotatably connected inside the fixing ring, a spring shaft rotatably connected to the right side of the fixing ring, a claw rod three fixedly connected to the outside of the spring shaft, a spring one fixedly connected inside the fixing ring, and an annular push block fixedly connected to the top of the spring one. As a further description of the above technical solution: The modular installation mechanism includes a base plate, a wedge-shaped strip is slidably connected inside the base plate, a support plate is fixedly connected to the rear side of the wedge-shaped strip, a limit plate is fixedly connected to the left side of the support plate, a rotating shaft is fixedly connected to the right side of the support plate, a limit block one is rotatably connected to the outside of the rotating shaft, and a spring two is fixedly connected to the bottom of the limit block one, and a limit block two is fixedly connected to the bottom of the spring two. As a further description of the above technical solution: The top of the annular pusher is in contact with the bottom of the first claw rod, and the bottom of the annular pusher is in contact with the bottom of the second claw rod; As a further description of the above technical solution: The base plate has screw holes inside, and the rear side of the base plate is slidably connected to the front side of the support plate. As a further description of the above technical solution: The left side of the first limiting block is in contact with the right side of the bracket plate, and the left side of the second limiting block is fixedly connected to the right side of the bracket plate. As a further description of the above technical solution: The front side of the hose clamp is fixedly connected to the outside of the bracket plate, and the left side of the base plate is in contact with the right side of the limiting plate; As a further description of the above technical solution: The rear side of the push rod is slidably connected to the front side of the cable bundle, and the right side of the base plate is in contact with the left side of the limiting block.

[0007] This utility model has the following beneficial effects: 1. In this utility model, pulling the push rod causes the sealing block to open, and then rotating the third claw rod clockwise causes it to open and close. The cable is placed at the intersection of the first and second claw rods. The weight of the cable will compress the bottom spring, causing the two claw rods to form a shear force and cross and fix it. After releasing the third claw rod, it and the other two claw rods together wrap the cable. As the number of cables increases, the three claw rods are squeezed and move towards the fixing ring until the cable is full. The claw rods fit against the inner wall of the fixing ring, realizing the ability to flexibly adjust the fixing state according to the number of cables. When there are a few cables, they can be stably fixed by the three claw rods to avoid friction with the cable bundle. When the number of cables increases, the claw rods can move towards the fixing ring to adapt, ensuring that different numbers of cables can be wrapped, protecting the cables and preventing the cables from tangling, improving the linearity and applicability of the device.

[0008] 2. In this utility model, the device is fixed to the object by a hose clamp. After adjusting the angle of the support plate, the hose clamp is tightened. The limiting block is rotated clockwise until it is perpendicular to the support plate. The base plate is inserted along the wedge strip into the connecting support plate until it abuts against the limiting plate. The limiting block is released to reset and restrict the movement of the base plate, thus completing the installation. Disassembly is performed by reversing the steps. The base plate can also be installed directly on the wall without the support plate, using the four corner screw holes. The support plate has various connection methods to adapt to different objects, achieving flexible angle adjustment and stable fixation. The installation and disassembly steps are simple and reversible. The base plate can also be installed directly on the wall or connected through the support plate, adapting to various scenarios. The modular design allows the support plate to change the connection method according to the size and shape of the object, improving the versatility of the device and providing convenient and adaptable installation support for the fixing mechanism.

[0010] 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.

[0011] Reference Figures 1 to 3An embodiment of this utility model is provided: a quick fixing device for cables used in broadcasting and television engineering, including a support beam 1, which is a component for connecting and supporting the device. A fixing mechanism 2 is fixedly connected to the front side of the support beam 1, and a modular installation mechanism 3 is fixedly connected to the rear side of the support beam 1. Hose clamps 4 are fixedly connected to both the left and right sides of the modular installation mechanism 3. The hose clamps 4 are used for modular installation, so that the device can be fixed on a non-planar object. The fixing mechanism 2 includes a cable bundle 21, the main function of which is to store and support cables. A closing block 22 is slidably connected inside the cable bundle 21. The closing block 22 slides inside the cable bundle 21 and can be manually operated to close or open it. It is used to close the cable bundle 21 after the cables are placed. A push rod 23 is fixedly connected to the front side of the closing block 22. The push rod 23 is the component that pushes the closing block 22 to open and close. A fixing ring 24 is fixedly connected to the right side of the cable bundle 21. The fixing ring 24 is fixed on the cable bundle 21 to support subsequent components. A cable fixing assembly 25 is rotatably connected inside the fixing ring 24. The cable fixing assembly 25 includes a first claw 251, which is rotatably connected inside the fixing ring 24 to cooperate with subsequent components to restrict the cable. A second claw 252 is rotatably connected inside the fixing ring 24. The second claw 252 crosses with the first claw 251, allowing the cable to be placed on it and detached from the inner wall of the cable bundle 21. A spring shaft 254 is rotatably connected to the right side of the fixing ring 24. The spring shaft 254 has a built-in torsion spring, causing the force of the spring shaft 254 to be applied in a counterclockwise direction. A third claw 253 is fixedly connected to the outside of the spring shaft 254. The third claw 253 is connected to the spring shaft 254 via a spring... The counterclockwise torque applied by the force shaft 254 causes it to cross above the first claw bar 251 and the second claw bar 252 and press down on the cable to fix it. A spring 255 is fixedly connected inside the fixing ring 24. The spring 255 is a component that pushes the first claw bar 251 and the second claw bar 252 to rotate upward. At the same time, the spring 255 can also be compressed into the groove inside the fixing ring 24. An annular push block 256 is fixedly connected to the top of the spring 255. The annular push block 256 pushes the first claw bar 251 and the second claw bar 252 to lift the cable by the elastic force applied by the spring 255.

[0012] Reference Figure 1 and Figure 4 The modular installation mechanism 3 includes a base plate 31, which is connected to a support beam 1, and the support beam 1 rests on the base plate 31. A wedge-shaped strip 32 is slidably connected inside the base plate 31. The wedge-shaped strip 32 and the dovetail groove on the base plate 31 form a mortise and tenon structure. A bracket plate 33 is fixedly connected to the rear side of the wedge-shaped strip 32. The bracket plate 33 and the wedge-shaped strip 32 form a spliced ​​whole. A limit plate 34 is fixedly connected to the left side of the bracket plate 33. The limit plate 34 prevents the base plate 31 from exceeding the wedge-shaped strip 32 when assembling the base plate 31. A rotating shaft 35 is fixedly connected to the right side of the support plate 33. The rotating shaft 35 is fixed on the support plate 33, and subsequent components are supported and rotated through it. A limit block 36 is rotatably connected to the outside of the rotating shaft 35. The limit block 36 is rotated to the right side of the base plate 31 through the rotating shaft 35 to limit it and prevent it from sliding to the right and disengaging from the wedge strip 32. A spring 37 is fixedly connected to the bottom of the limit block 36. The spring 37 is a tension spring used to pull the limit block 36 to limit the base plate 31. A limit block 38 is fixedly connected to the bottom of the spring 37. The limit block 38 is responsible for fixing the spring 37 so that it maintains the tension on the limit block 36, and also restricts the limit block 36 to remain in a near-horizontal state.

[0013] Reference Figures 2 to 4 The top of the annular push block 256 contacts the bottom of the claw rod 251. The annular push block 256, pushed upwards by the spring 255, pushes the claw rod 251 to press the cable to be fixed on it. The bottom of the annular push block 256 contacts the bottom of the claw rod 252. The annular push block 256, pushed upwards by the spring 255, pushes the claw rod 252 to press the cable to be fixed on it. Screw holes 39 are provided inside the base plate 31, one at each corner. When fixing to a wall, these holes may not be necessary. The bracket plate 33 is installed, and the rear side of the base plate 31 is slidably connected to the front side of the bracket plate 33. The base plate 31 is spliced ​​with the wedge strip 32 on the bracket plate 33 through the dovetail groove, so the base plate 31 can slide off the bracket plate 33. The left side of the limiting block 36 is in contact with the right side of the bracket plate 33. The limiting block 36 is pressed against by the base plate 31, and the force it bears can be transmitted to the bracket plate 33 through the rear side to ensure its stability. The left side of the limiting block 38 is fixedly connected to the right side of the bracket plate 33. The limiting block 38 is fixed by the bracket plate 33 and supports the spring 37. The front side of the hose clamp 4 is fixedly connected to the outside of the support plate 33. The upper and lower ends of the left side of the hose clamp 4 are fixed to the bottom and bottom of the support plate 33, respectively. When fixed to the object being supported, tightening the hose clamp 4 causes the support plate 33 to adhere to the object and be fixed. The left side of the base plate 31 is in contact with the right side of the limiting plate 34. When the base plate 31 slides to the left, it is in contact with the right side of the limiting plate 34. The rear side of the push rod 23 is slidably connected to the front side of the cable bundle 21. The push rod 23 opens and closes the cable bundle 21 by controlling the push and pull of the closing block 22. The outside of the cable bundle 21 is provided with damping so that the push rod 23 is automatically fixed in a certain position. The right side of the base plate 31 is in contact with the left side of the limiting block 36. When the base plate 31 slides to the right, it is limited by the limiting block 36 and abuts against the limiting block 36.

[0014] Working principle: When using the device, if the number of cables to be placed is small, first pull down the push rod 23 to open the closing block 22. Then, rotate the claw rod three 253 clockwise to adjust its opening angle. Place the cable at the intersection of claw rod one 251 and claw rod two 252. At this time, the weight of the cable itself will compress the spring one 255 at the bottom, so that the claw rods form a shear force cross structure to achieve initial fixation. Then, release the claw rod three 253 to tightly press the cable. Finally, the three claw rods together wrap and fix the cable, effectively preventing the cable from rubbing against the inner wall of the cable bundle 21. As the number of cables gradually increases, the three claw rods will slowly move towards the fixing ring 24 until the inside of the cable bundle 21 is full of cables. At this time, the claw rods will be completely attached to the inner wall of the fixing ring 24, completing the cable bundling operation.

[0015] During installation, the hose clamp 4 is fixed to the object to be installed. The angle of the support plate 33 is adjusted to a suitable position and the hose clamp 4 is tightened. The limiting block 36 is manually rotated clockwise to be perpendicular to the support plate 33. The base plate 31 is inserted into the connecting support plate 33 along the wedge strip 32 until it abuts against the limiting plate 34. The limiting block 36 is released to reset the movement of the base plate 31, thus completing the installation of the device. The disassembly of the device is the reverse of the installation. In addition, the base plate 31 can also be installed directly on the wall without the support plate 33, relying on the screw holes 39 at the four corners. It should be noted that the connection method between the support plate 33 and the object does not only depend on the hose clamp 4. This is a modular splicing device. The connection method of the support plate 33 can also be fixed according to objects of different sizes and shapes. It is mainly used to provide more convenient installation for the fixing mechanism 2.

[0016] 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.
