[0018] Please see Figure 2-12 The present invention provides the following technical solution: a cable support device for broadcast television coverage project, including a U-shaped fixing frame 1, with L-shaped fixing plates 2 fixedly connected to the upper and lower ends and the front and rear sides of the right side of the U-shaped fixing frame 1, and fixing holes 3 opened on the L-shaped fixing plates 2. The L-shaped fixing plates 2 with fixing holes 3 are used to fix and install the device on the wall or other building. Several U-shaped support frames 6 are provided on the left side of the U-shaped fixing frame 1, wherein the U-shaped support frames 6 are used for cable support; Two guide shafts 11 are fixedly connected to the upper right side of the U-shaped support frame 6. A limiting protrusion 12 is fixedly connected to the upper end of each guide shaft 11. A spring 13 is fitted around the outer perimeter of the right guide shaft 11. A pressure rod 15 is provided at the upper end of the U-shaped support frame 6. Two guide holes 16 are opened inside the right end of the pressure rod 15, and the guide shaft 11 is slidably connected to the guide holes 16. A cavity 17 is opened inside the left end of the pressure rod 15. A limiting block 18 is slidably connected to the left end of the cavity 17.

The inner bottom surface of the U-shaped support frame 6 and the bottom surface of the pressure rod 15 are both bonded with anti-slip pads 9, which are made of rubber. The structure is designed to allow for rapid retraction and extension of the pressure rod 15, making operation effortless and convenient. The sliding fit between the guide shaft 11 and the guide hole 16 ensures smooth up-and-down movement of the pressure rod 15, preventing it from moving forward, backward, left, or right during this movement. Spring 13 allows the pressure rod 15 to automatically spring back and return to its original position after being released from its limiting state. The limiting protrusion 12 limits the upper ends of the guide shaft 11 and the pressure rod 15 to prevent it from popping off the guide shaft 11. The cavity 17 and spring 20 allow the limiting block to... The elastic extension and retraction of 18 allows the limiting teeth 19 at the left end of the limiting block 18 to automatically engage with the limiting groove 14 at the left end of the U-shaped support frame 6. The slot 21, connecting shaft 22, and push bar 23 are designed to facilitate manual push-pull operation of the limiting block 18, allowing for quick release of the engagement between the limiting teeth 19 at the left end of the limiting block 18 and the limiting groove 14 at the left end of the U-shaped support frame 6.

The surface of the anti-slip pad 9 is integrally formed with anti-slip texture, which is not specifically shown in the figure.

[0019] In this embodiment: When in use, the cable can be supported by several U-shaped support frames 6 on one side of the U-shaped fixing frame 1. At the same time, by pressing down on the pressure rod 15 at the upper end of the U-shaped support frame 6, the cable on the U-shaped support frame 6 can be further pressed and fixed through the cooperation between the pressure rod 15 and the U-shaped support frame 6. The operation is simple, the support is stable, and the cable is not easy to move or sag. With the arrangement and cooperation of the guide shaft 11, the limiting protrusion 12, the spring 13, the limiting block 18, the limiting tooth 19, and the limiting tooth groove 14, the pressure rod 15 can be self-locked after being pressed down, making the operation more labor-saving and convenient. In addition, through the arrangement and cooperation of the above structure, the pressure rod 15 can be quickly released and reset, so that the cable on the U-shaped support frame 6 can be further inspected or replaced. Overall, the use is better.

[0020] Furthermore, refer to Figure 4 , Figure 5 and Figure 6 As shown, the inner side of the U-shaped fixing frame 1 is integrally formed with several insertion cavities 4, and the right end of the U-shaped support frame 6 is inserted into the insertion cavity 4. The right end of the U-shaped support frame 6 is fixedly connected with a screw shaft 7. Several insertion holes 5 are opened on the right side of the U-shaped fixing frame 1 and the insertion holes 5 are located on the right side of the insertion cavity 4. The screw shaft 7 is inserted into the insertion hole 5, and the right end of the screw shaft 7 is screwed with a locking nut 8. The right end of the U-shaped support frame 6 is chamfered around its perimeter so that the right end of the U-shaped support frame 6 can be smoothly inserted into the insertion cavity 4 when inserted.

[0021] In this embodiment: the U-shaped support frame 6 in this utility model can be quickly assembled and disassembled relative to the U-shaped fixing frame 1 through the arrangement and cooperation of the screw shaft 7, the insertion cavity 4, the insertion hole 5 and the locking nut 8, making it more convenient to use.

[0022] Furthermore, refer to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, side support plates 10 are fixedly connected to both the front and rear sides of the U-shaped support frame 6. The upper end of the side support plate 10, which is different from the U-shaped support frame 6, is chamfered to ensure smooth contact between the bottom of the cable and the outer edge of the side support plate 10. This avoids the bottom of the cable rubbing against the sharp edge of the side support plate 10, which is not chamfered, and thus prevents the cable from being damaged by friction.

[0023] In this embodiment: the side support plates 10 on both sides of the U-shaped support frame 6 can further increase the support area of ​​the bottom of the cable on the U-shaped support frame 6, so that the cable can be supported more stably and used more conveniently.

[0024] The usage process and working principle of this utility model are as follows: In use, the device can be fixedly installed in a suitable position using bolts and the fixing holes 3 on the L-shaped fixing plate 2. Then, several cable racks can be placed on the U-shaped support frame 6, positioned below the pressure rod 15, through the opening between the upper left end of the U-shaped support frame 6 and the bottom left end of the pressure rod 15. Next, the pressure rod 15 is pressed downwards relative to the U-shaped support frame 6. During this process, the sliding cooperation between the guide through hole 16 and the guide shaft 11 guides and limits the downward movement of the pressure rod 15. This allows the pressure rod 15 to move downwards smoothly. During the downward movement of the pressure rod 15, the spring 13 located on the guide shaft 11 between the pressure rod 15 and the U-shaped support frame 6 will be compressed. At the same time, the left end of the pressure rod 15 is located in the cavity 17 and can be elastically extended and retracted by the spring 20. The left end has several limiting teeth 19, which can automatically engage with the limiting tooth groove 14 on the inner side of the left end of the U-shaped support frame 6. This can achieve self-locking fixation of the pressure rod 15 after being pressed down. Through the cooperation between the pressure rod 15 and the U-shaped support frame 6, the cables installed on the U-shaped support frame 6 can be pressed and fixed. In the future, if it is necessary to inspect or replace the cables on the U-shaped support frame 6, the limit block 18 can be pushed to the right by the push bar 23 and the connecting shaft 22, so that the limit teeth 19 on the left end of the limit block 18 are separated from the limit groove 14, so as to quickly release the limit fixation state of the pressure rod 15. At the same time, under the elastic force of the spring 13, the pressure rod 15 after the limit is released can automatically spring back and move upward, so as to facilitate further loading and unloading of cables on the U-shaped support frame 6.

[0025] In addition, all content not described in detail in this embodiment falls within the scope of existing technology and common knowledge.

[0026] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
