Description

Technical Field

[0001] The present application relates to the technical field of leaky cable fixing, and in particular to a leaky cable clamp for tunnels. Background Art

[0002] Leaky coaxial cable is referred to as leaky cable or leaky cable for short. During the laying of railway cables, it is necessary to use leaky cable clamps made of plastic material to clamp and support the leaky cable when passing through tunnels, and fix it to the inner wall of the tunnel through expansion fasteners, so that the leaky cable clamps are distributed along the laying direction of the leaky cable to form a stable support and fixing system.

[0003] In the laying of railway cables, not only leaky cables are laid, but also electrical cables, optical cables and other cables are laid along the line. At present, additional clamps are added to the same leaky cable fixture to clamp and fix multiple cables at the same time. However, the current clamps usually have fixed clamping sizes and cannot be applied to multiple working conditions, resulting in poor cable clamping effect. Utility Model Content

[0035] Reference Figure 1 and Figure 2 The embodiment of the present application provides a leaky cable clamp for a tunnel, comprising a first base 1, the first base 1 having a first clamping groove 2 for accommodating a leaky cable, and the leaky cable clamp further comprising:

[0036] A cable clamping assembly 3, the cable clamping assembly 3 includes a second base 4 and a clamping structure 5, the second base 4 is connected to one end of the first base 1, a second clamping groove 12 is formed between the clamping structure 5 and the second base 4, one end of the clamping structure 5 is rotatably connected to the second base 4, and the clamping structure 5 can be limited on the second base 4 so that the clamping structure 5 maintains a clamping state; and,

[0037] The cover plate 22 is used to close the first clamping groove 2 and the second clamping groove 12 .

[0038] In this embodiment, the first clamping groove 2 is used to accommodate leaky cables, and the second clamping groove 12 is usually used to accommodate cables other than leaky cables. When the number of leaky cables is large and the first clamping groove 2 cannot meet the clamping requirements of the leaky cables, the second clamping groove 12 can also be used to accommodate leaky cables. One end of the clamping structure 5 described above is rotatably connected to the second base 4, and the clamping structure 5 can be fixed on the second base 4, which means that the clamping structure 5 cannot rotate when it is fixed, that is, the clamping structure 5 maintains a clamping state when it is fixed, so that the cable is clamped and fixed. The clamping structure 5 can rotate when it is not fixed, that is, the size of the clamping range of the second clamping groove 12 is adjusted by rotating the clamping structure 5. When it is adjusted to a suitable range size, the clamping structure 5 can be fixed.

[0039] It is understandable that the fixing method for the clamping structure 5 can adopt the connection methods such as snaps, pins or bolts in the existing technology, as long as it can ensure that the clamping structure 5 can be fixed to the second base 4 and can be released to achieve rotation. Therefore, no further details will be given here.

[0040] The leaky cable clamp for tunnel of the above embodiment comprises a first base 1, a cable clamping assembly 3 and a cover plate 22, wherein the cable clamping assembly 3 comprises a second base 4 and a clamping structure 5, and a second clamping groove 12 is formed between the clamping structure 5 and the second base 4. That is, when the second clamping groove 12 cannot meet the clamping requirements of the cable, the clamping structure 5 and the second base 4 are first adjusted to a non-fixed state, and then the clamping structure 5 is rotated in a direction away from the second clamping groove 12 so that the clamping range of the second clamping groove 12 is increased, and then the clamping structure 5 is fixed. Similarly, when the second clamping groove 12 needs to clamp fewer cables, in order to clamp the cables more firmly, the clamping structure 5 and the second base 4 are first adjusted to a non-fixed state, and then the clamping structure 5 is rotated in a direction close to the second clamping groove 12 so that the clamping range of the second clamping groove 12 is reduced, and then the clamping structure 5 is fixed. Therefore, the leaky cable clamp of the embodiment of the present application can be applied to a variety of working conditions and has strong applicability.

[0041] As an optional implementation, refer to Figure 1 and Figure 2 The second base 4 is formed by extending from one end of the first base 1 , and the clamping structure 5 is connected between the second base 4 and the first base 1 .

[0042] In this embodiment, the second base 4 is formed by extending one end of the first base 1 , that is, the second base 4 and the first base 1 may be an integral structure to enhance the stability of the second base 4 and the first base 1 .

[0043] As an optional implementation, refer to Figures 1 to 4 , the clamping structure 5 includes a clamping protrusion 10 and a clamping portion 11;

[0044] The engaging protrusion 10 is disposed between the second base 4 and the first base 1. The engaging protrusion 10 is provided with an engaging through hole 17. The engaging protrusion 10 is provided with at least one engaging groove 16 in the circumferential direction of the engaging through hole 17. A separator 14 is disposed between every two adjacent engaging grooves 16.

[0045] The clamping portion 11 includes a clamping block 23 adapted to the clamping groove 16 , and one end of the clamping portion 11 is rotatably connected to the clamping protrusion 10 via the clamping through hole 17 .

[0046] It is understandable that the existing leaky cable clamp is made of plastic material, so the components of the leaky cable clamp have a certain elasticity. Therefore, in this embodiment, the clamping portion 11 is used to clamp and fix the cable, and the clamping protrusion 10 is used as a connecting component between the clamping portion 11 and the second base 4 and the first base 1.

[0047] In the specific implementation process, when it is necessary to increase the clamping range of the second clamping groove 12, the clamping part 11 is held and rotated in the direction away from the second clamping groove 12. When the clamping part 11 rotates, the block 23 will move the partition 14. Since the partition 14 has a certain elasticity, the partition 14 is deformed by the extrusion force, so that the block 23 rotates to the corresponding other engaging groove 16. At this time, the partition 14 is restored to its original state under the action of the elastic restoring force. The block 23 is now limited in the other engaging groove 16, and the clamping part 11 can be fixed again so that the clamping part 11 cannot rotate. Similarly, when it is necessary to reduce the clamping range of the second clamping groove 12, the clamping part 11 is held and rotated in the direction close to the second clamping groove 12 so that the block 23 is engaged in the corresponding other engaging groove 16. By cooperating with the engaging protrusion 10 and the clamping portion 11 in this embodiment, when adjusting the clamping range of the second clamping groove 12, there is no need to repeatedly disassemble parts, and only the clamping portion 11 needs to be rotated, thereby saving manpower and time costs.

[0048] In some embodiments, reference Figure 4In order to facilitate the block 23 to move the separator 14, the separator 14 can be set to a conical structure, and the pointed end of the conical structure is set toward the block 23, so that the block 23 can scrape the separator 14.

[0049] As an optional implementation, refer to Figures 3 to 5 , the clamping portion 11 includes a clamping member 15 and a rotating member 18;

[0050] A first connecting groove 19 adapted to the engaging protrusion 10 is provided in the middle of one end of the clamping member 15 close to the engaging protrusion 10, and connecting through holes 20 adapted to the rotating member 18 are provided at both ends of the clamping member 15 located at the first connecting groove 19;

[0051] The clamping block 23 is connected to the rotating member 18 . The rotating member 18 is disposed through the connecting through hole 20 and the clamping through hole 17 . When the rotating member 18 performs a rotational motion, it can drive the clamping member 15 to rotate.

[0052] In this embodiment, by providing a first connection groove 19 in the middle of one end of the clamping member 15, the engaging protrusion 10 is embedded in the middle position of the end of the clamping member 15. When installing the clamping member 15, the clamping member 15 is first clamped on the engaging protrusion 10, and then the rotating member 18 is sequentially passed through the first connecting through hole 20, the connecting through hole 17 and the second connecting through hole 20 of the clamping member 15, and the clamping block 23 is clamped into the corresponding engaging groove 16. Finally, the rotating member 18 is connected to the clamping member 15, or the rotating member 18 and the clamping member 15 are interference fit, so that when the rotating member 18 rotates, it can drive the clamping member 15 to rotate.

[0053] As an optional implementation, refer to Figure 5 The clamping member 15 is also provided with a second connecting groove 21 adapted to the clamping block 23 , and the clamping block 23 is extended along the long axis direction of the rotating member 18 .

[0054] In this embodiment, the block 23 is extended to engage with the second connecting groove 21. When the rotating member 18 is rotated, the engagement between the block 23 and the second connecting groove 21 can drive the clamping member 15 to rotate without the need for additional connecting components.

[0055] As an optional implementation, refer to Figure 1 and Figure 5 , limit blocks 7 are provided at both ends of the rotating member 18.

[0056] In this embodiment, limit blocks 7 are provided at both ends of the rotating member 18 to prevent the rotating member 18 from escaping from the clamping member 15 and the engaging protrusion 10 , thereby ensuring the connection stability of the clamping member 15 , the rotating member 18 and the engaging protrusion 10 .

[0057] As an optional implementation, refer to Figure 1 and Figure 5 , there is an operating hole 6 on the limit block 7.

[0058] In this embodiment, an external tool is inserted into the operation hole 6 to rotate the rotating member 18 .

[0059] As an optional implementation, refer to Figure 1 and Figure 5 The operation hole 6 includes a first hole body 8 and a second hole body 9, and the first hole body 8 and the second hole body 9 are vertically arranged.

[0060] In this embodiment, the first hole 8 and the second hole 9 are vertically arranged, which is equivalent to a cross hole, so that the rotating member 18 can be rotated by using a simple tool such as a screwdriver.

[0061] As an optional implementation, refer to Figures 1 to 3 A first pressing sheet 24 matched with the first clamping groove 2 and a second pressing sheet 13 matched with the second clamping groove 12 are arranged on the inner side of the cover plate 22 .

[0062] In this embodiment, the cross section of the first pressing sheet 24 is V-shaped, one end of the first pressing sheet 24 is connected to the cover plate 22, and the other end of the first pressing sheet 24 is a free end. There are two first pressing sheets 24 and they are symmetrical about the axis of the first clamping groove 2, and the free ends of the two first pressing sheets 24 are in an eight-shaped shape. The cover plate 22 drives the two first pressing sheets 24 to press the leaky cable so as to fix the leaky cable in the first clamping groove 2.

[0063] The second pressing piece 13 is used to press the cable in the second clamping groove 12 downward from the top. Under the elastic force of the second pressing piece 13, the clamping stability of the cable is further improved.

[0064] As an optional implementation, refer to Figures 1 to 3 Both ends of the cover plate 22 are snap-connected with the base.

[0065] In this embodiment, when installing the cover plate 22, the two ends of the cover plate 22 are bent in opposite directions, and the cover plate 22 is placed on the first base 1 and the second base 4, and then the two ends of the cover plate 22 are loosened, so that one end of the cover plate 22 is engaged with one end of the first base 1, and the other end of the cover plate 22 is engaged with one end of the second base 4, thereby easily completing the installation of the cover plate 22.
