Description

Technical Field

[0001] The present invention relates to the technical field of cable clamps, and specifically to a leaky coaxial cable clamp. Background Art

[0002] Through the innovative design of "wired transmission and wireless coverage", leaky cables solve the communication problems in enclosed spaces and complex environments. They are key infrastructure in fields such as rail transit, public safety, and industrial Internet of Things. They can be used in areas where signals cannot cover, such as tunnels, to ensure communication in the tunnels. Leaky cable clamps can fix leaky cables in tunnels.

[0003] In a leaky coaxial cable clamp disclosed in the publication number CN103644381A, it includes a support seat, a cover plate body hinged to the support seat, and a locking member for locking the support seat and the cover plate body. An arc-shaped locking member locks the cable-bearing part of the support seat and the cover plate body to form an annular clamp, which clamps the leaky coaxial cable by applying force from all around. And an elastic body sheath is provided for use in cooperation with the leaky coaxial cable clamp to absorb vibrations and pressures from the cover plate body and the cable-bearing part, protect the cable-bearing part and the cover plate body, and prevent wear. However, when using the above-mentioned clamp, it can only fix leaky cables that match it. Since the diameters of each cable are different, different sizes of cable clamps are required for fixing, which reduces the practicality of the cable clamps. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention proposes a leaky coaxial cable clamp.

[0005] To achieve the above object, the present invention provides the following technical solution: A leaky coaxial cable clamp includes a bracket. Above the bracket, there are two support inclined frames. One of the support inclined frames is fixedly connected to the bracket, and below the other support inclined frame, there is an adjustment fixing member. The upper surface of the support inclined frame is fixedly connected with a fixing component, and the inner wall of the support inclined frame is fixedly connected with a support bar, and a strip-shaped groove is opened on one side side wall of the support bar.

[0006] Preferably, the support bar is made of a flexible material.

[0007] Preferably, glue is provided in the strip-shaped groove, a liquid storage and ventilation groove is opened on one side side wall of the strip-shaped groove, and a release paper covers one side of the support bar, and the release paper seals the strip-shaped groove and the liquid storage and ventilation groove.

[0008] Preferably, the adjustment fixing member includes a limit block fixedly connected to the support inclined frame. A sliding groove is opened on the upper surface of the bracket, and the limit block is slidably connected to the inner wall of the sliding groove. A threaded hole is opened on the lower surface of the limit block, and a fixing bolt is provided in the threaded hole.

[0009] Preferably, the fixing assembly includes a fixing belt fixedly connected to one of the supporting oblique frames, and one side wall of the fixing belt is fixedly connected with a first oblique tooth, the upper surface of the other supporting oblique frame is fixedly connected with a clamping block, and one side wall of the clamping block is provided with an insertion hole, the lower surface of the clamping block is provided with a clearance groove, a limiting plate is arranged in the clearance groove, and the upper surface of the limiting plate is fixedly connected with a second oblique tooth, and a spring sheet is arranged below the limiting plate.

[0010] Preferably, a pressure rod is fixedly connected to the upper surface of the limiting plate, and one end of the pressure rod passes through the block and extends to be arranged above the block, and one end of the pressure rod located above the block is fixedly connected to the pressure block.

[0011] Preferably, a gasket is sleeved on the outer wall of the fixing bolt, and a side wall of the gasket is in contact with the bracket.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention can support cables by arranging two support bars for use in conjunction with support bevel frames, and by arranging an adjustment fixture, the position of one of the support bevel frames can be adjusted, so that the device can support cables of different sizes, thereby improving the practicality of the device.

[0014] The present invention provides a support bar made of a flexible material so that the support bar can undergo a certain deformation when supporting the cable, thereby allowing the support bar to fit the cable more closely. This increases the contact area between the support bar and the cable, which can reduce the pressure between the support bar and the cable, thereby protecting the cable. The provision of a strip groove facilitates the deformation of the support bar.

[0015] The present invention sets glue, liquid storage ventilation groove and release paper for use together. After the cable is placed on the support bar, so that one side of the support bar is formed into a groove matching the cable, the release paper on the side wall of the support bar is lifted up to expose the strip groove and the liquid storage ventilation groove to the air. In this way, the glue is in contact with the air, so that the glue can solidify. The solidified glue can connect the support bar with the strip groove, thereby enhancing the strength of the support bar and allowing the support bar to form a stable shape.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Please refer to Figures 1 - 8 , a leaky coaxial cable clamp, including a bracket 1, two support inclined frames 2 are arranged above the bracket 1, one of the support inclined frames 2 is fixedly connected to the bracket 1, an adjusting and fixing member is arranged below the other support inclined frame 2, a fixing component is fixedly connected to the upper surface of the support inclined frame 2, and a support bar 3 is fixedly connected to the inner wall of the support inclined frame 2, and a strip-shaped groove 4 is opened on one side side wall of the support bar 3.

[0027] It can be seen from the above structure that by arranging two support bars 3 and the support inclined frame 2 in cooperation, the cable can be supported, and by arranging the adjusting and fixing member, the position of one of the support inclined frames 2 can be adjusted, which enables the device to support cables of different sizes, thereby improving the practicability of the device.

[0028] Furthermore, the support bar 3 is made of a flexible material; by arranging the support bar 3 made of a flexible material, when the support bar 3 supports the cable, the support bar 3 can undergo a certain deformation, so that the support bar 3 can fit the cable more closely, thereby increasing the contact surface between the support bar 3 and the cable, reducing the pressure between the support bar 3 and the cable, and thus protecting the cable.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Furthermore, a gasket 22 is sleeved on the outer wall of the fixing bolt 11, and one side wall of the gasket 22 contacts the bracket 1; by providing the gasket 22, the bracket 1 can be prevented from being damaged by the fixing bolt 11.

[0034] In the present invention, during use, first, the bracket 1 is fixed to the inner wall of the tunnel by expansion bolts, and then the positions of the two supporting inclined frames 2 are adjusted according to the size of the cable to be fixed. When adjusting, the fixing bolt 11 is turned open, and then one of the supporting inclined frames 2 is slid, and then the fixing bolt 11 is tightened again, so that the supporting bars 3 on the two supporting inclined frames 2 form a V-shaped groove, and the cable can be placed in the V-shaped groove. Subsequently, one end of the fixing band 12 is passed through the insertion hole 15, and then the fixing band 12 is tightened, so that the fixing band 12 presses the cable in the V-shaped groove;

[0035] Due to the extrusion of the cable, one side of the supporting bar 3 is deformed into a groove matching the cable, which increases the contact area with the cable, reduces the pressure between the supporting bar 3 and the cable, and thus protects the cable. The provided strip-shaped groove 4 facilitates the deformation of the supporting bar 3;

[0036] Subsequently, the release paper 7 on the side wall of the supporting bar 3 can be lifted, so that the strip-shaped groove 4 and the liquid storage and ventilation groove 6 are exposed to the air, so that the adhesive 5 contacts the air, and the adhesive 5 can solidify. The solidified adhesive 5 can connect the supporting bar 3 provided with the strip-shaped groove 4, enhance the strength of the supporting bar 3, and at the same time enable the supporting bar 3 to form a stable shape;

[0037] When the cable is released, the pressing block 21 can be pressed, so that the pressing block 21 presses down the push rod 20. The downwardly moving push rod 20 drives the limiting plate 17 and the second helical gear 18 to move downward. After the second helical gear 18 moves downward, the fixing band 12 can be withdrawn.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
