Description

Technical Field

[0001] The utility model relates to the technical field of railway electrical accessories, and particularly relates to a fixture fixing system for a short embedded channel. Background Art

[0002] A leaky cable is short for a leaky coaxial cable, and the leaky coaxial cable has a signal transmission function and an antenna function. Generally, it is laid along a railway line during construction. After the laid line enters a tunnel, the leaky cable needs to be fixed on the inner wall of the tunnel. Usually, an expansion anchor bolt and a leaky cable fixture are used in cooperation to fix the leaky cable, and the expansion anchor bolt needs to be installed in the tunnel wall in advance during installation. However, during the tunnel construction process, due to the error between the design and the actual construction, or the situation that the construction is not strictly carried out according to the drawings, the embedded channel is short (that is, the length of the embedded channel is insufficient), which may cause the subsequent components for fixing the leaky cable to be unable to be fully installed in place. In this way, not only the bearing capacity of the fixture fixing device will be reduced, but also the safety of the equipment, pipelines or tracks in the tunnel will be affected, and even accidents may be caused in extreme cases.

[0003] The purpose of the present invention is to provide a fixture fixing system for a short embedded channel to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present disclosure provides a fixture fixing system for a short embedded channel, including:

[0005] A chuck;

[0006] A mounting member, at least a part of the mounting member is used to be arranged in the embedded channel, and at least another part of the mounting member is used to extend outside the embedded channel;

[0026] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0027] In the description of the present disclosure, in the present disclosure, unless otherwise stated, "inner" and "outer" refer to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have sequentiality and importance.

[0028] In the description of the present disclosure, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "connected", "coupled", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0029] As Figures 1 to 3 shown, the present disclosure provides a fixture fixing system for a relatively short embedded channel, including a chuck 10, a mounting member 20, and an installation bracket 30. At least part of the mounting member 20 is configured to be disposed within the embedded channel 40, and at least another part of the mounting member 20 is configured to extend outside the embedded channel 40. The first end of the installation bracket 30 is connected to the chuck 10, and the second end of the installation bracket 30 is movably connected to at least another part of the mounting member 20.

[0030] Through the above technical solution, one end of the mounting bracket 30 can be connected to the chuck 10 for fixing the leaky cable, and the other end of the mounting bracket 30 can be movably connected to the embedded groove 40 through the mounting member 20. That is to say, the mounting bracket 30 can be used to increase the available length of the embedded groove 40, that is, the mounting bracket 30 can play a role in expanding or lengthening the length of the embedded groove 40. Such a design is beneficial to improving the flexibility and accuracy of the fixture. Even when the length of the embedded groove 40 is insufficient, it can ensure that the leaky cable can be firmly and safely installed at the designated position, without damaging the cable, and can maintain good electrical performance and mechanical stability in the harsh tunnel environment for a long time.

[0031] Among them, the chuck 10 is used to fix the leaky cable.

[0032] Among them, the embedded groove 40 is a groove or channel pre-set in the structure before concrete pouring. The embedded groove 40 can be linear, U-shaped, T-shaped or other shapes. The embedded groove 40 in the present disclosure is configured as a U-shaped structure.

[0033] As an implementation manner, as Figure 2 shown, at least two through holes 31 are formed on the second end of the mounting bracket 30. The at least two through holes 31 are arranged at intervals along the length direction of the mounting bracket 30. At least another part of the mounting member 20 is used to selectively connect to one of the at least two through holes 31 to mount the mounting bracket 30 on the embedded groove 40.

[0034] Since at least two through holes 31 are provided on the second end of the mounting bracket 30, any through hole 31 can be connected to the part of the mounting member 20 extending outside the embedded groove 40. That is, the mounting bracket 30 can provide multiple connection points. The installer can select the most suitable through hole 31 to connect to the embedded groove 40 through the mounting member 20. Such a setting can, on the one hand, enhance the adaptability of the fixture fixing system provided by the present disclosure, so that the entire fixture fixing device can be adapted to embedded grooves 40 of different lengths, and on the other hand, it can avoid complex measurements or on-site cutting adjustments by the installer, thereby improving the installation efficiency and reducing the labor cost. As an implementation manner, as Figure 2 shown, the mounting member 20 includes a fixed part and an adjusting part that are detachably connected. The fixed part is configured as a fixing bolt 21, and the connecting part is configured as a nut 22. The bolt rod of the fixing bolt 21 is used to sequentially pass through the slot opening 41 of the embedded groove 40 and the corresponding through hole 31 above the slot opening 41 to be connected to the nut 22.

[0035] During the installation process, the bolt rod of the fixing bolt 21 first passes through the notch 41 of the embedded groove 40, then through a through hole 31 on the mounting bracket 30, and finally connects to the nut 22 of the adjusting part. That is to say, by tightening the nut 22, the mounting bracket 30 can be firmly fixed on the embedded groove 40, thus ensuring the stability and safety of the fixture fixing system.

[0036] In addition, the detachable connection between the fixing bolt 21 and the nut 22 facilitates future maintenance or replacement.

[0037] As an implementation manner, as Figure 2 shown, the diameter of the bolt head of the fixing bolt 21 is greater than the width of the notch 41 and less than or equal to the width of the embedded groove 40, and the diameter of the bolt rod of the fixing bolt 21 is less than or equal to the width of the notch 41.

[0038] Among them, the bolt head of the fixing bolt 21 can be accommodated in the embedded groove 40 and cannot pass through the notch 41, which can not only prevent the fixing bolt 21 from falling off from the notch 41 of the embedded groove 40, but also make the fixture fixing system more compact and beautiful.

[0039] As an implementation manner, as Figure 2 shown, the mounting bracket 30 includes a first part 32, a middle part 33 and a second part 34. The first part 32 and the second part 34 are respectively connected to both ends of the middle part 33 and extend in directions away from each other. The first part 32 is connected to the chuck 10, and at least two through holes 31 are formed on the second part 34.

[0040] The first part 32 and the second part 34 extend in directions away from each other. That is, the mounting bracket 30 is configured as a Z-shaped structure. With such a design, in the case of limited space, the span of the mounting bracket 30 can be expanded, providing a larger support area and a suitable installation position for mounting the chuck 10, thereby enhancing the stability of the overall structure. At the same time, the Z-shaped structure helps to disperse and reduce local stress, evenly distribute the weight on different parts of the bracket, and improve the overall stability and load-bearing capacity.

[0041] As an implementation manner, as Figure 2 shown, the fixture fixing system further includes a fastener 50, and the chuck 10 is detachably connected to the first part 32 through the fastener 50.

[0042] By providing the fastener 50, the chuck 10 can be firmly fixed on the first part 32 of the mounting bracket 30 while retaining the detachable feature, which means that when maintenance, adjustment or replacement of components is required, the chuck 10 can be easily separated without damaging other components.

[0043] As an implementation manner, asFigure 2 As shown, the fastener 50 includes a first bolt and a first nut 22. A through hole is formed on the chuck 10. The first bolt is used to pass through the through hole and the first part 32 to be connected to the first nut 22.

[0044] The through hole formed on the chuck 10 is aligned with the mounting hole on the first part 32. The first bolt passes through these two through holes 31 and then is tightened with the first nut 22. By tightening the nut 22, the reliability of the connection can be ensured, thus providing sufficient strength and stability. This connection method allows for fine-tuning the position of the chuck 10 during installation or adjustment. Additionally, the combination of the bolt and the nut 22 allows for easy disassembly and reinstallation when needed, facilitating maintenance and replacement.

[0045] As another embodiment, as Figure 2 shown, the fastener 50 includes a connecting screw and a connecting nut 22. The first end of the connecting screw is connected to the outer side surface of the chuck 10, and the second end of the connecting screw is used to pass through the first part 32 to be connected to the connecting nut 22.

[0046] One end of the connecting screw is fixed on the outer side surface of the chuck 10, and the other end passes through the through hole 31 on the first part 32 and then is tightened and fixed with the connecting nut 22. Since one end of the connecting screw is already fixed on the chuck 10, the installation process can be more convenient, only needing to align the connecting screw with the mounting hole on the first part 32 and tighten it with the connecting nut 22.

[0047] In addition, the connecting screw is fixed on the chuck 10, reducing the risk of bolt loss, especially in hard-to-reach or complex working environments.

[0048] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0049] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0050] Furthermore, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
