When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0034] After analysis, it is found that when using the existing leaky cable clamp to clamp and fix multiple cables at the same time, the clamp structure with two threading grooves is usually formed in one piece. This structure is large in size. When it is not necessary to clamp and fix cables other than the leaky cable, the clamping structure for clamping the cable cannot be disassembled as needed. Or a complex structure is used to install an additional clamping structure for clamping the cable on one side of the original leaky cable clamp. When installing and removing the clamping structure, it is time-consuming and labor-intensive, and inconvenient to operate.

[0035] Therefore, in order to facilitate the installation and disassembly of the clamping structure, an embodiment of the present application proposes a new multi-purpose leaky cable clamp.

[0036] Reference Figure 1 and Figure 2 A multi-purpose leaky cable clamp comprises a base 1, a cover plate 3 and a clamping structure.

[0037] The base 1 has a first threading groove 2 for accommodating the leaky cable, and a connecting groove body 7 is provided on the base 1. The connecting groove body 7 is used to install the clamping structure, so that when it is not necessary to clamp and fix the remaining cables other than the leaky cable, the clamping structure is separated from the connecting groove body 7 and the clamping structure is disassembled.

[0038] The cover plate 3 is disposed on the base 1 so that the cover plate 3 closes the first threading groove 2 .

[0039] The clamping structure includes a clamping component 4 and a limiting component 5. The clamping component 4 has a second threading groove 6 for accommodating cables. The second threading groove 6 is used to accommodate other cables other than the leaky cable, or can be used to accommodate excess leaky cables when the first threading groove 2 cannot meet the requirements for the clamping of the leaky cable. The clamping component 4 is embedded in the connecting groove 7, and the limiting component 5 is used to limit the clamping component 4 so that the clamping component 4 cannot be removed from the connecting groove 7.

[0040] A multi-purpose leaky cable clamp of the above embodiment comprises a base 1 having a first threading groove 2 for accommodating the leaky cable, a cover plate 3 for closing the first threading groove 2 and a clamping structure for clamping and fixing the cable, wherein the clamping structure comprises a clamping assembly 4 and a limiting assembly 5, the clamping assembly 4 having a second threading groove 6 for accommodating the cable, the clamping assembly 4 being embedded in the connecting groove body 7, and the limiting assembly 5 being used to limit the clamping assembly 4 so that the clamping assembly 4 is always embedded in the connecting groove body 7. When it is necessary to clamp and fix the remaining cables other than the leaky cable, the clamping assembly 4 is embedded in the connecting groove body 7, and then the limiting assembly 5 is installed, so that the clamping assembly 4 is limited in the connecting groove body 7, and the installation of the clamping assembly 4 can be completed. When it is not necessary to clamp and fix the remaining cables other than the leaky cable, the limiting assembly 5 is first disassembled, and then the clamping assembly 4 is taken out from the connecting groove body 7, and the disassembly of the clamping assembly 4 can be completed. Therefore, the installation and disassembly steps of the clamping assembly 4 in the embodiment of the present application are simple, which can be convenient for operators to operate.

[0041] As an optional implementation, refer to Figures 1 to 3 , the clamping assembly 4 includes a clamping portion 41 and a connecting portion 42 connected as one body;

[0042] The connecting groove 7 is located on a side wall of the base 1, and the connecting groove 7 is formed by the base 1 from an end away from the cover plate 3 to an end close to the cover plate 3;

[0043] The connecting portion 42 is embedded in the connecting groove 7 , and the limiting assembly 5 is disposed at one end of the connecting groove 7 away from the cover plate 3 .

[0044] In this embodiment, the clamping portion 41 is used to clamp and fix the cable, and the connecting portion 42 is used to connect with the base 1. When installing the clamping assembly 4, the connecting portion 42 is inserted from the entrance end of the connecting groove 7 and continues to be pushed toward the inside of the connecting groove 7. The entrance end of the connecting groove 7 refers to the end of the connecting groove 7 away from the cover plate 3, and then the limiting assembly 5 is installed to the entrance end of the connecting groove 7, so that the limiting assembly 5 closes the entrance end of the connecting groove 7, so that the connecting portion 42 is limited in the connecting groove 7.

[0045] As an optional implementation, refer to Figure 1 and Figure 3 The horizontal cross-section of the connecting groove body 7 is T-shaped, and the large end 71 of the connecting groove body 7 is far away from the clamping part 41, and the small end 72 of the connecting groove body 7 is close to the clamping part 41; the connecting part 42 includes a first body 421 adapted to the large end 71 and a second body 422 adapted to the small end 72.

[0046] In this embodiment, when the connection part 42 is embedded in the connection groove body 7, the first part 421 is embedded in the large end 71 of the connection groove body 7, and the second part 422 is located at the small end 72 of the connection groove body 7, and extends out of the connection groove body 7 and is connected to the clamping part 41, so that the clamping part 41 is fixed on the base 1. The structure of the connection groove body 7 and the connection part 42 is simple, easy to manufacture, and can ensure the connection stability of the clamping part 41.

[0047] As an optional implementation, refer to Figure 4 , both sides of the first body 421 are inclined surfaces 424.

[0048] In this embodiment, the two sides of the first part 421 mentioned above refer to the opposite sides where the first part 421 contacts the connecting groove body 7. When the connecting part 42 is pushed from the entrance end of the connecting groove body 7 to the inside of the connecting groove body 7, the first part 421 will generate friction with the groove wall of the connecting groove body 7. Therefore, in order to facilitate pushing the first part 421, the two sides of the first part 421 are set as inclined surfaces 424 to reduce the contact area between the first part 421 and the connecting groove body 7, thereby helping the connecting part 42 to be embedded and slide into the connecting groove body 7.

[0049] After the fixture clamps and fixes the leaky cable or other cables, the leaky cable or other cables may vibrate due to the movement of vehicles in the tunnel. When the leaky cable or other cables vibrate, the fixture or clamping part 41 will be driven to vibrate synchronously. If the limit component 5 and the clamping component 4 are set closely together, the connecting part 42 will hit the limit component 5 when it moves relative to the base 1. Therefore, during the design and production, a certain gap may be left between the limit component 5 and the connecting part 42 to provide a certain displacement range for the connecting part 42. Therefore, in order to increase the friction between the connecting part 42 and the base 1 and avoid a large displacement of the connecting part 42, refer to Figure 4 An anti-slip portion 423 is provided on a surface of the first body 421 facing the base 1 to enhance the friction between the connecting portion 42 and the base 1 .

[0050] However, it should be noted that in order to ensure the convenience of embedding and sliding the connecting part 42 into the connecting groove body 7 as mentioned above, the total thickness of the first part 421 and the anti-slip part 423 can be slightly smaller than the groove body thickness of the large end 71 of the connecting groove body 7. When the connecting part 42 is embedded from the entrance end of the connecting groove body 7, the holding clamping part 41 is pulled slightly away from the base 1, and then the clamping assembly 4 is slid into the interior of the connecting groove body 7, so that the connecting part 42 can be easily embedded and slid into the connecting groove body 7.

[0051] As an optional implementation, refer to Figure 2 and Figure 3 The limit assembly 5 is snap-connected with the base 1. The snap-connection method can make it easier to install the limit assembly 5, so that the installation and removal of the clamping assembly 4 can be completed quickly, saving time and effort.

[0052] As an optional implementation, refer to Figure 5 The limiting assembly 5 includes a first limiting portion 54, a fixing block 51, a first elastic sheet 52, a second elastic sheet 53 and a second limiting portion 55;

[0053] The first elastic sheet 52 and the second elastic sheet 53 are connected to the two ends of the fixing block 51 respectively, and the first elastic sheet 52, the fixing block 51 and the second elastic sheet 53 are adapted to the large end 71 of the connecting groove 7; the first limiting portion 54 is connected to the first elastic sheet 52, and the second limiting portion 55 is connected to the second elastic sheet 53;

[0054] A first limiting through hole 9 matched with the first limiting portion 54 and a second limiting through hole 10 matched with the second limiting portion 55 are respectively formed on both sides of the large end 71 of the base 1 .

[0055] In this embodiment, the first spring sheet 52 and the second spring sheet 53 are elastic, that is, when the first spring sheet 52 and the second spring sheet 53 are in a natural state, the total length of the first limiting portion 54, the fixing block 51, the first spring sheet 52, the second spring sheet 53 and the second limiting portion 55 is greater than the width of the large end 71; when the first spring sheet 52 and the second spring sheet 53 are in a compressed state, the total length of the first limiting portion 54, the fixing block 51, the first spring sheet 52, the second spring sheet 53 and the second limiting portion 55 is less than or equal to the width of the large end 71.

[0056] Specifically, when installing the limit assembly 5, the first limit portion 54 and the second limit portion 55 are squeezed in opposite directions so that the limit assembly 5 is embedded in the large end 71, and then the limit assembly 5 is pushed toward the inside of the connecting groove body 7. When the limit assembly 5 moves to the position of the first limit through hole 9 and the second limit through hole 10, under the elastic action of the first spring piece 52 and the second spring piece 53, the first limit portion 54 is snapped into the first limit through hole 9, and the second limit portion 55 is snapped into the second limit through hole 10, so that the limit assembly 5 can be fixed on the base 1.

[0057] As an optional implementation, refer to Figure 5 The first spring piece 52 and the second spring piece 53 are both integrally formed with the fixing block 51 , and there is a gap between the first spring piece 52 and the second spring piece 53 and the fixing block 51 .

[0058] In this embodiment, the elastic margin is provided by the gaps between the first elastic sheet 52 and the second elastic sheet 53 and the fixing block 51 , and the structure is simple.

[0059] As an optional implementation, refer to Figures 1 to 4 The clamping portion 41 includes a first clamping portion 411 and a second clamping portion 412. A second threading groove 6 is formed between the first clamping portion 411, the connecting portion 42 and the second clamping portion 412. The first clamping portion 411 and the second clamping portion 412 are connected in a detachable manner.

[0060] In this embodiment, the first clamp 411 and the second clamp 412 are connected in a detachable manner, which is equivalent to being able to be connected and separated from each other. When clamping and fixing the cable, the first clamp 411 and the second clamp 412 are directly disassembled to separate the first clamp 411 and the second clamp 412, and the cable can be wrapped. Then, the first clamp 411 and the second clamp 412 are connected to complete the clamping and fixing of the cable.

[0061] As an optional implementation, refer to Figures 1 to 4 The first clamping portion 411 is fixedly connected to the connecting portion 42 , one end of the second clamping portion 412 is fixedly connected to the connecting portion 42 , and the other end of the second clamping portion 412 is connected to the first clamping portion 411 via a snap-fitting member 8 .

[0062] In this embodiment, when clamping and fixing the cable, the end of the second clamp 412 connected to the first clamp 411 is pried open to allow the engaging member 8 to detach from the first clamp 411, and then the second clamp 412 is continued to be pried open to wrap the clamping portion 41 around the cable, and finally the engaging member 8 is buckled onto the first clamp 411. The operation is simple and convenient.

[0063] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
