[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. 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.

[0032] In railway construction, not only leaky cables are laid, but also electrical cables, optical cables and other cables are laid along the line. When multiple groups of cables need to be clamped and fixed, another clamping component will be additionally installed on the base of the existing plastic leaky cable clamp.

[0033] However, since the width of the base will be widened after the clamping assembly is installed on the base, when multiple groups of cables do not need to be clamped and fixed, the widened base may interfere with the surrounding area during installation, thereby affecting the installation efficiency of the fixture. Therefore, in order to avoid the idle clamping assembly from interfering with the surrounding area, the clamping assembly often needs to be removed from the base, and the clamping assembly needs to be reinstalled when it is needed next time. The steps are cumbersome and inconvenient for flexible use.

[0034] Therefore, in order to facilitate the flexible use of the additional clamping assembly, the embodiment of the present application proposes a new leaky cable clamp.

[0035] Reference Figure 1 and Figure 2 The leaky cable clamp includes a base 1, a cover plate 2 and a clamping assembly 5.

[0036] The base 1 is provided with a first clamping groove 3, and the first clamping groove 3 is used to accommodate the leaky cable.

[0037] The cover plate 2 is covered on the base 1 to close the first clamping groove 3. A receiving groove 4 is opened on one side wall of the base 1. The receiving groove 4 is used to receive the clamping assembly 5 so that the clamping assembly 5 can be received.

[0038] The clamping assembly 5 has a second clamping groove 6, which is used to accommodate cables other than leaky cables. One end of the clamping assembly 5 is rotatably connected to the base 1; when the clamping assembly 5 is rotated to the clamping position, it can be limited; when the clamping assembly 5 is in an idle state, the clamping assembly 5 is rotated to the storage position and is stored in the storage groove 4.

[0039] The idle state refers to a state when no cables other than the leaky cable need to be clamped and fixed. The clamping position refers to a state when the clamping assembly 5 and the base 1 form a second clamping groove 6. The storage position refers to a state when the clamping assembly 5 is stored in the storage groove.

[0040] In a specific implementation process, when it is necessary to clamp and fix cables other than the leaky cable, the clamping assembly 5 is rotated from the storage slot 4 to a clamping state, and then the clamping assembly 5 is fixed so that the clamping assembly 5 remains in the clamping state and cannot rotate. When it is not necessary to clamp and fix cables other than the leaky cable, the clamping assembly 5 is released from the fixed state and rotated into the storage slot 4 so that the clamping assembly 5 is stored in the storage slot 4.

[0041] It should be noted that the clamping assembly 5 can be fixed by existing threaded connection, pin connection, snap connection or key connection. When the clamping assembly 5 is in the clamping state, the clamping assembly 5 is fixed; when the clamping assembly 5 is in the idle state, the fixing effect on the clamping assembly 5 is canceled.

[0042] The leaky cable clamp of the above embodiment includes a base 1, a cover plate 2 and a clamping assembly 5. The base 1 is provided with a first clamping groove 3. The cover plate 2 is covered on the base 1. A storage groove 4 is provided on one side wall of the base 1. The clamping assembly 5 has a second clamping groove 6. One end of the clamping assembly 5 is rotatably connected to the base 1. When the clamping assembly 5 and the base 1 form a clamping state, the clamping assembly 5 can be fixed to the base 1. When the clamping assembly 5 is in an idle state, the clamping assembly 5 is rotated into the storage groove 4. That is, when it is not necessary to clamp and fix cables other than the leaky cable, the present application can directly realize the storage of the clamping assembly 5 by rotating the clamping assembly 5 into the storage groove 4. The steps are simple and the position of the clamping assembly 5 can be flexibly adjusted.

[0043] As an optional implementation, refer to Figure 1 and Figure 2 , the clamping assembly 5 includes a first clamping portion 7, a second clamping portion 8 and a limiting portion 9;

[0044] The first clamping portion 7 is connected to the side wall of the base 1;

[0045] The second clamping portion 8 and the first clamping portion 7 form a second clamping groove 6, and one end of the second clamping portion 8 away from the first clamping portion 7 is rotatably connected to the base 1;

[0046] When the second clamping portion 8 and the first clamping portion 7 form a clamping state, the limiting portion 9 is used to limit the rotation of the second clamping portion 8 .

[0047] In this embodiment, the first clamping portion 7 can be formed by extending the side wall of the base 1, that is, the first clamping portion 7 and the base 1 are an integral structure, and the first clamping portion 7 cooperates with the second clamping portion 8 to form the second clamping groove 6. Through the cooperation of the first clamping portion 7 and the second clamping portion 8, the width of the second clamping portion 8 can be reduced, and the width of the first clamping portion 7 is also smaller than the width of the cover plate 2, and will not cause interference to the surrounding area. At the same time, since the width of the second clamping portion 8 is reduced, the depth requirement of the storage groove 4 is reduced, so that the second clamping portion 8 can achieve a better hiding effect.

[0048] It is understandable that the above-mentioned limiting portion 9 can adopt existing components such as the above-mentioned bolts, pins, buckles or keys to limit the rotation of the second clamping portion 8.

[0049] As an optional implementation, refer to Figures 1 to 3 The limiting portion 9 is connected to the base 1, and the limiting portion 9 is close to one end of the second clamping portion 8 that is rotatably connected to the base 1. A limiting groove 10 is provided on the limiting portion 9, and a clamping portion 11 that is adapted to the limiting groove 10 is connected to the second clamping portion 8; the second clamping portion 8 can be pulled so that the clamping portion 11 is disengaged from the limiting groove 10.

[0050] It is known that the components of the existing leaky cable clamp are usually made of plastic, so each component has elastic force.

[0051] In this embodiment, the limiting portion 9 may be formed by extending the side wall of the base 1, that is, the limiting portion 9 is located on the side wall of the base 1. When the first clamping portion 7 and the second clamping portion 8 are in the clamping state, the clamping portion 11 is located in the limiting groove 10 so that self-rotation cannot occur, thereby making the first clamping portion 7 and the second clamping portion 8 in the clamping state.

[0052] In some embodiments, in order to cooperate with the rotation of the second clamping portion 8, the limiting portion 9 can be set to an arc shape. The number of limiting grooves 10 can also be multiple, and the limiting grooves 10 are arranged along the circumferential direction of the limiting portion 9, so that the clamping portion 11 can be engaged in different limiting grooves 10, thereby increasing or reducing the clamping range of the second clamping groove 6.

[0053] During the specific implementation process, when the second clamping part 8 needs to be stored in the storage slot 4, the second clamping part 8 is held by hand, and under the elastic action of the base 1 and the second clamping part 8, the second clamping part 8 is pulled horizontally in the direction away from the base 1, so that the clamping part 11 disengages from the limiting groove 10, and then the second clamping part 8 is rotated so that the second clamping part 8 is hidden in the storage slot 4.

[0054] It should be noted that the storage groove 4 can be set in the clockwise or counterclockwise direction of the second clamping portion 8 according to actual needs, that is, it can be set on the side of the side wall of the base 1 close to the cover plate 2 or away from the cover plate 2, as long as the extension width of the second clamping portion 8 after storage is smaller than the width of the cover plate 2.

[0055] As an optional implementation, refer to Figure 1 and Figure 3 There are two limit portions 9 and two clamping portions 11 , which are respectively connected to the base 1 and the two sides of the second clamping portion 8 .

[0056] In this embodiment, two limiting portions 9 and the clamping portion 11 are symmetrically arranged, so that both sides of the second clamping portion 8 can be limited and fixed, thereby achieving a better fixing effect on the second clamping portion 8 .

[0057] As an optional implementation, refer to Figure 1 The first clamping portion 7 has a receiving opening 12 communicated with the receiving groove 4 , and the receiving opening 12 is adapted to the second clamping portion 8 .

[0058] In this embodiment, the first clamping portion 7 has a first clamping protrusion and a second clamping protrusion, and the first clamping protrusion and the second clamping protrusion are respectively located on both sides of the second clamping portion 8, and a storage opening 12 is formed between the first clamping protrusion and the second clamping protrusion. When storing the second clamping portion 8, the second clamping portion 8 is held and rotated to pass through the storage opening 12 and be stored in the storage groove 4, that is, the storage groove 4 is located on the side close to the first clamping portion 7.

[0059] In some embodiments, the first clamping portion 7 can be set on the side of the side wall of the base 1 away from the cover plate 2. Since this side of the base 1 is close to the small end of the first clamping groove 3, when the first clamping portion 7 is set on this side, the depth of the storage groove 4 on this side is deeper, thereby achieving a better hiding effect for the second clamping portion 8.

[0060] As an optional implementation, refer to Figure 1 and Figure 4 The outer wall of the second clamping portion 8 is provided with a convex portion 17, which can facilitate holding the second clamping portion 8 so as to rotate the second clamping portion 8.

[0061] As an optional implementation, refer to Figure 1, Figure 3 and Figure 4 The clamping assembly also includes a connecting member 13, which is located in the receiving groove 4 and connected to the base 1. A connecting hole 14 adapted to the connecting member 13 is opened in the middle of one end of the second clamping portion 8 close to the base 1.

[0062] In this embodiment, one end of the connecting member 13 extends from the inside of the storage groove 4 to the outside of the storage groove 4, and is rotatably connected to the second clamping portion 8, so that a better elastic force can be provided to the second clamping portion 8, so that after the second clamping portion 8 is pulled horizontally, the connecting member 13 is subjected to tension and provides a reaction force to the second clamping portion 8 under its own elastic force.

[0063] In the specific implementation process, when the second clamping portion 8 is in the storage state, the second clamping portion 8 and the connecting portion are in a natural connection state, that is, at this time, the connecting member 13 is not subjected to tension and is in a normal state. When the cable needs to be clamped and fixed, the second clamping portion 8 is rotated to be out of the storage slot 4, and the clamping portion 11 will slide along the arc of the limiting portion 9. At this time, the clamping portion 11 will be displaced in the direction away from the base 1, so the connecting member 13 will be subjected to tension and deformed. When the clamping portion 11 moves to the limiting slot 10, the second clamping portion 8 is slowly released. Under the reaction force of the connecting member 13, the second clamping portion 8 is pulled toward the direction close to the base 1, that is, the clamping portion 11 is clamped into the limiting slot 10, so that the second clamping portion 8 is fixed, thereby preventing the second clamping portion 8 from rotating.

[0064] As an optional implementation, refer to Figure 3 One end of the connecting member 13 close to the second clamping portion 8 extends toward the base 1 to form a first extending portion 15 .

[0065] In this embodiment, the connecting member 13 of the first extending portion 15 can not only better cooperate with the rotation of the second clamping portion 8 , but also facilitate the disassembly of the second clamping portion 8 .

[0066] As an optional embodiment, a second extension portion (not shown) is extended from one end of the connector 13 close to the base 1. The second extension portion is formed extending around the connector 13, thereby increasing the connection area between the connector 13 and the base 1, thereby enhancing the tensile strength of the connector 13.

[0067] In order to enhance the connection stability between the second clamping portion 8 and the base 1, refer to Figure 4 Optionally, rotating parts 16 are provided on both sides of one end of the second clamping part 8 close to the connecting piece 13, and rotating holes matching the rotating parts 16 are opened on both sides of the inner wall of the base 1, and the diameter of the rotating hole is larger than the diameter of the rotating part 16 to provide displacement space for the second clamping part 8.

[0068] In some embodiments, in order to facilitate the disassembly of the second clamping portion 8, the second clamping portion 8 is symmetrically provided with two gap portions between the two rotating portions 16, and elastic margins are provided through the two gap portions. When the second clamping portion 8 needs to be disassembled, the two sides of the second clamping portion 8 are squeezed in opposite directions so that the rotating portions 16 on both sides are close to each other, thereby disengaging from their respective rotating holes, and then the second clamping portion 8 can be removed from the connecting member 13.

[0069] 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.
