It is a key infrastructure in the fields of rail transit, public safety, industrial Internet of Things, etc. It can be used in areas such as tunnels where signals cannot cover to ensure communication in tunnels. The leaky cable clamp can fix the leaky cable in the tunnel.

[0003] A leaky coaxial cable clamp is disclosed in publication number CN103644381A, which includes a support seat, a cover plate body hinged to the support seat, and a locking piece for locking the support seat and the cover plate body. The cable holding part of the support seat and the cover plate body are locked by the arc-shaped locking piece to form an annular clamp, which clamps the leaky coaxial cable by applying force on all sides, and an elastomeric sheath used in conjunction with the leaky coaxial cable clamp is provided to absorb vibration and pressure from the cover plate body and the cable holding part, protect the cable holding part and the cover plate body, and prevent wear. However, when the above-mentioned clamp is used, it can only fix the leaky cable matched with it. Each cable has a different diameter, so it needs a cable clamp of different sizes to fix it, which reduces the practicality of the cable clamp. Summary of the invention

[0019] It can be seen from the above structure that: by setting two support bars 3 and using them in conjunction with the supporting inclined frames 2, cables can be supported, and by setting an adjustment fixing, the position of one of the supporting inclined frames 2 can be adjusted, which allows the device to support cables of different sizes, thereby improving the practicality of the device.

[0020] Furthermore, the support bar 3 is made of a flexible material; by providing the support bar 3 with a flexible material, the support bar 3 can undergo a certain deformation when supporting the cable, so that the support bar 3 can fit the cable more closely, thereby increasing the contact area between the support bar 3 and the cable, and reducing the pressure between the support bar 3 and the cable, thereby protecting the cable.

[0021] Furthermore, glue 5 is arranged in the strip groove 4, and a liquid storage and ventilation groove 6 is opened on one side wall of the strip groove 4, and one side of the support bar 3 is covered with a release paper 7, and the release paper 7 seals the strip groove 4 and the liquid storage and ventilation groove 6; by setting the glue 5, the liquid storage and ventilation groove 6 and the release paper 7 for use together, after the cable is placed on the support bar 3 so that one side of the support bar 3 is deformed into a groove matching the cable, the release paper 7 on the side wall of the support bar 3 is lifted, so that the strip groove 4 and the liquid storage and ventilation groove 6 are exposed to the air, so that the glue 5 contacts the air, so that the glue 5 can solidify, and the solidified glue 5 can be connected to the support bar 3 with the strip groove 4, so as to enhance the strength of the support bar 3 and at the same time enable the support bar 3 to form a stable shape.

[0022] Furthermore, the adjustment fixing member includes a limit block 8 fixedly connected to the supporting inclined frame 2, a slide groove 9 is provided on the upper surface of the bracket 1, and the limit block 8 is slidably connected to the inner wall of the slide groove 9, a threaded hole 10 is provided on the lower surface of the limit block 8, and a fixing bolt 11 is provided in the threaded hole 10; by setting the limit block 8 and the fixing bolt 11 for use in conjunction with each other, the position of the two supporting inclined frames 2 can be adjusted according to the size of the fixed cable as needed. When adjusting, turn off the fixing bolt 11, then slide one of the supporting inclined frames 2, and then re-tighten the fixing bolt 11, so that the support bars 3 on the two supporting inclined frames 2 form a V-shaped groove.

[0023] Furthermore, the fixing component includes a fixing belt 12 fixedly connected to one of the supporting oblique frames 2, and a first oblique tooth 13 is fixedly connected to one side wall of the fixing belt 12, a clamping block 14 is fixedly connected to the upper surface of the other supporting oblique frame 2, and a hole 15 is opened on one side wall of the clamping block 14, and a clearance groove 16 is opened on the lower surface of the clamping block 14, a limiting plate 17 is arranged in the clearance groove 16, and a second oblique tooth 18 is fixedly connected to the upper surface of the limiting plate 17, and a spring sheet 19 is arranged under the limiting plate 17; by setting the fixing belt 12 and the clamping block 14 for use in combination, the cable can be fixed. When fixing the cable, one end of the fixing belt 12 is passed through the hole 15, and then the fixing belt 12 is tightened, so that the fixing belt 12 can press the cable into the V-shaped groove. When the cable is loosened, the limiting plate 17 is pressed down, so that the limiting plate 17 and the second oblique tooth 18 move downward. After the second oblique tooth 18 moves downward, the fixing belt 12 can be pulled out.

[0024] Furthermore, a pressure rod 20 is fixedly connected to the upper surface of the limit plate 17, and one end of the pressure rod 20 passes through the block 14 and extends to the top of the block 14, and one end of the pressure rod 20 located above the block 14 is fixedly connected to a pressure block 21; by arranging the pressure rod 20 and the pressure block 21 to be used in conjunction with each other, the limit plate 17 can be pressed down, and when the limit plate 17 is pressed down, the pressure block 21 can be pressed, so that the pressure block 21 presses the pressure rod 20 down, and the downwardly moved pressure rod 20 drives the limit plate 17 and the second bevel tooth 18 to move downward.

[0025] Furthermore, a gasket 22 is sleeved on the outer wall of the fixing bolt 11 , and one side wall of the gasket 22 is in contact with the bracket 1 ; by providing the gasket 22 , the fixing bolt 1 can be prevented from crushing the bracket 1 .

[0026] In the present invention, when in use, first fix the bracket 1 to the inner wall of the tunnel by the expansion bolts, then adjust the positions of the two supporting oblique frames 2 according to the size of the fixed cable, when adjusting, turn the fixing bolts 11, then slide one of the supporting oblique frames 2, and then tighten the fixing bolts 11 again, so that the support bars 3 on the two supporting oblique frames 2 form a V-shaped groove, and the cable can be placed in the V-shaped groove, and then one end of the fixing belt 12 can be passed through the insertion hole 15, and then the fixing belt 12 is tightened, so that the fixing belt 12 presses the cable into the V-shaped groove; Due to the extrusion of the cable, one side of the support bar 3 is deformed into a groove matching the cable, which increases the contact area with the cable and can reduce the pressure between the support bar 3 and the cable, thereby protecting the cable. The strip groove 4 can facilitate the deformation of the support bar 3; Then, the release paper 7 on the side wall of the support strip 3 can be lifted to expose the strip groove 4 and the liquid storage vent groove 6 to the air, so that the glue 5 is in contact with the air and can solidify. The solidified glue 5 can connect the support strip 3 with the strip groove 4 to enhance the strength of the support strip 3 and form a stable shape. When loosening the cable, the pressing block 21 can be pressed to make the pressing block 21 press down the pressing rod 20. The pressing rod 20 moving downward drives the limiting plate 17 and the second bevel gear 18 to move downward. After the second bevel gear 18 moves downward, the fixing belt 12 can be pulled out.
