[0028] Reference Figure 1 and Figure 2 One embodiment of the present invention includes a middle layer component 2 that is sleeved on the outside of four sets of inner layer components 1 and has a covering. The middle layer component 2 has a groove that matches the inner layer components 1. An outer layer component 3 is provided on the outside of the middle layer component 2. The outer layer component 3 includes a first protective layer 31 and a second protective layer 32 sleeved on the outside of the first protective layer 31.
[0029] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5The protective assembly includes an inner layer assembly 1, a middle layer assembly 2, and an outer layer assembly 3. To increase the bending resistance of the video transmission line, the inner layer assembly 1 includes a transmission line 11, which is wrapped with a first wrapping layer 12. The first wrapping layer 12 is then wrapped with a second wrapping layer 13. The use of the first and second wrapping layers 12 increases the device's anti-interference and bending resistance. A series of support assemblies 14 are evenly distributed on the outer side of the second wrapping layer 13. Support rods 15 are arranged between the four sets of second wrapping layers 13. The use of the support rods 15 allows the four sets of transmission lines to approach each other and transmit video around the support rods 15, enhancing the bending resistance of the video transmission. This is achieved through the inclusion of the inner layer assembly 1. With the cooperation of support component 14 and support rod 15, the bending strength of the device is greatly improved. The support rod 15 has a fixing groove that matches the support component 14, so that the support component 14 and the support rod 15 can be firmly matched to achieve fixed support for the video transmission line. The support component 14 includes a socket post 141, and a support post 142 is sleeved on the outside of the socket post 141. The support post 142 has a socket groove that matches the socket post 141. The use of socket post 141 and support post 142 allows the four sets of transmission lines to be firmly set inside the middle layer component 2, preventing the lines from getting tangled and causing line damage. By setting the middle layer component 2, the protection of the device is greatly enhanced.
[0030] It is worth noting that the transmission line in the above embodiment is a four-coaxial transmission line, which is used to better illustrate the structural features of this utility model. However, this utility model is not limited to a four-coaxial transmission line, and can also be other types of transmission lines, such as multi-core cables, dual coaxial transmission lines, or more coaxial transmission lines. In different application scenarios, the appropriate type of transmission line can be selected according to actual needs.
[0031] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 To enhance the device's protective properties, the middle layer component 2 has a groove that mates with the inner layer component 1, allowing the middle layer component 2 to wrap around the inner layer component 1, thus increasing the device's protective properties. The outer layer component 3 includes a first protective layer 31, with a second protective layer 32 sleeved on the outside of the first protective layer 31. The use of the first protective layer 31 and the second protective layer 32 allows the device to insulate heat while being more wear-resistant, increasing the device's service life. By setting the outer layer component 3 and the interlocking between the first protective layer 31 and the second protective layer 32, the device's protective properties are greatly enhanced. The first protective layer 31 has a fixing groove that mates with the inner layer component 1, allowing the outer layer component 3 to provide good protection.
[0032] In one embodiment, the first wrapping layer 12 is made of conductive polyethylene, a low-cost thermoplastic polymer material with good compatibility with carbon black. The second wrapping layer 13 is made of natural rubber, which has excellent resilience, insulation, water resistance, and plasticity. The middle layer component 2 is made of polyethylene (PE), which has good wettability, heat resistance, mechanical strength, and toughness. The first protective layer 31 is made of ceramic fiberboard, which has good heat insulation effect. The second protective layer 32 is made of wear-resistant rubber, which increases the service life of the video transmission line due to its wear resistance.
[0033] In one embodiment, a filler material is provided between the middle layer component (2) and the outer layer component (3) for filling the gap between them.
[0034] In this embodiment, the filling material can be polyurethane foam, which has good cushioning and insulation properties, effectively absorbing external impacts and protecting the internal transmission lines from damage. The use of polyurethane foam not only improves the overall structural stability but also enhances the bending resistance of the video transmission lines. In another embodiment, the support rod 15 can be made of high-strength aluminum alloy, which is lightweight and high-strength, effectively supporting four sets of transmission lines and ensuring stable video signal transmission. The surface of the support rod 15 can also be anodized to improve its corrosion resistance and extend the service life of the video transmission lines.
[0035] In another embodiment of this utility model, the sleeve post 141 and the support post 142 can be made of metal materials, such as stainless steel, to ensure that the support assembly 14 has sufficient strength and durability. The connection between the sleeve post 141 and the support post 142 can be a threaded connection, which facilitates installation and disassembly, as well as maintenance and replacement of damaged parts.
[0036] In one embodiment, the inner layer component (1) is connected to connectors at both ends, the connectors being used to connect to transmission cables; an elastic buffer layer is provided between the first protective layer (31) and the second protective layer (32); the outer surface of the second protective layer (32) has an anti-slip texture, the anti-slip texture being raised in shape.
[0037] In this embodiment, the elastic buffer layer can be made of silicone, which has good elasticity and resistance to high and low temperatures, effectively absorbing vibration and impact, and protecting the connector and transmission cable from damage. The elastic buffer layer not only improves the stability and reliability of the connection, but also further enhances the bending resistance of the video transmission line. In another embodiment, the anti-slip texture can be striped or dotted, which can provide sufficient friction to prevent the video transmission line from sliding or falling off during use, ensuring a stable connection of the transmission cable. The anti-slip texture improves the ease of operation and enhances the durability of the overall structure. In yet another embodiment of this utility model, the inner surface of the middle layer component (2) can be provided with an anti-static coating to prevent static electricity from interfering with the transmission line and to ensure the clarity and stability of the video signal. The use of the anti-static coating not only improves the anti-interference ability of the video transmission line, but also ensures safety during transmission. In yet another embodiment of this utility model, the two ends of the support rod (15) can be provided with fixing devices, such as slots or threaded holes, to fix the support rod in a specific position and prevent it from shifting during use. The design of the fixing device not only improves the stability of the support rod, but also ensures the correct installation and use of the video transmission cable.
[0038] In one specific embodiment, during use, the mobile video transmission line is significantly improved in terms of bending resistance under the action of the support component 14 and the support rod 15, preventing the line from folding and affecting signal transmission. The use of the middle layer component 2 and the outer layer component 3 greatly improves the protection of the video transmission line, greatly increasing the service life of the device and reducing wear and tear.
