[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1-4 , a cable pillow support for a cable tray, comprising a plurality of cable fixing members 1, the cable fixing members 1 are installed on the cable tray 2, each cable fixing member 1 includes a first cable clamping member 11 and a second cable clamping member 12, and the first cable clamping member 11 and the second cable clamping member 12 are connected by tenon and mortise joints to form a through hole for clamping the cable 3.

[0020] In this embodiment, through the tenon and mortise connection between the first cable clamping member 11 and the second cable clamping member 12, a stable and adjustable clamping space is formed, which can effectively clamp the cable 3, prevent the cable 3 from moving or shaking on the cable tray 2, reduce the friction and extrusion of the cable 3 on the tray, ensure the stability and safety of the cable 3, thereby extending the service life of the cable 3. At the same time, since the first cable clamping member 11 and the second cable clamping member 12 adopt the tenon and mortise connection method, the installation and disassembly are relatively simple, and no complex tools or equipment are required, which not only reduces the difficulty of installation and maintenance, but also improves the work efficiency. In addition, by using the cable pillow support, the cable 3 can be neatly fixed on the cable tray 2, avoiding the mess of the cable 3 and making the cable tray 2 look more beautiful and tidy.

[0021] It should be noted that the installation distance of the cable pillow support can be determined according to the installation distance of the cable tray 2. It is recommended that the installation distance be 1.5 m to 3 m. The use of the cable pillow support can improve the flexibility, clarity of the cable 3 layout, and facilitate the user's later maintenance and management of the cable 3. In the power system, by using the expandable cable pillow support, the cable 3 can be arranged orderly in its position, avoiding the mess of the cable 3 and ensuring the neatness of the cable 3 wiring. In the later renovation project, the cable 3 can be quickly located, which brings convenience to the later management.

[0022] Preferably, the first cable clamp 11 includes a first clamp body 111. At the top of the first clamp body 111, there is a first groove 112 for clamping the cable and a second groove 113 for mortise and tenon connection with the second cable clamp 12.

At the bottom of the second clamp body 121, there is a third groove 122 matching the first groove 112 and a first protrusion 123 matching the second groove 113. The second groove 113 and the first protrusion 123 achieve mortise and tenon connection, and the first groove 112 and the third groove 122 form a through hole for clamping the cable 3.

[0023] In this embodiment, the first groove 112 on the first clamp body 111 and the third groove 122 on the second clamp body 121 match each other. When combined, they form a through hole that can precisely clamp the cable 3. This design ensures that the cable 3 can be stably fixed on the cable tray 2, reducing the shaking and movement of the cable 3. At the same time, the second groove 113 on the first clamp body 111 and the first protrusion 123 on the second clamp body 121 achieve mortise and tenon connection. This connection method is not only simple in structure but also firm in connection, effectively preventing the clamp from loosening or separating under the weight of the cable or external force. In addition, due to the matching design of the first groove 112 and the third groove 122, as well as the second groove 113 and the first protrusion 123, the clamping force can be adjusted by finely tuning the relative position between the first clamp 11 and the second clamp 12 according to the diameter of the cable 3. This design makes the cable pillow have better adaptability and versatility and is suitable for cables of different diameters.

[0024] Preferably, a second protrusion 13 is provided on the first side of each cable fixing member 1, and a fourth groove 14 is provided on the second side of each cable fixing member 1. The second protrusion 13 and the fourth groove 14 match each other to achieve mortise and tenon connection.

[0025] In this embodiment, through the mortise and tenon connection between the cable fixing members 1, multiple cable fixing members 1 can be tightly connected together to form an integral structure. The mortise and tenon connection design makes the installation and disassembly of the cable fixing members 1 relatively simple. The staff only needs to align the first side and the second side of adjacent cable fixing members 1, and then insert the second protrusion 13 into the fourth groove 14 to complete the connection. Similarly, when disassembling, only need to pull out the second protrusion 13 from the fourth groove 14. In addition, since the cable fixing members 1 are connected by mortise and tenon, the number of cable fixing members 1 can be flexibly increased or decreased according to the actual length of the cable tray. This design makes the cable pillow have good adaptability and versatility and can meet the requirements of cable trays of different lengths.

[0026] Preferably, fifth grooves 124 are provided on both sides of the second clamping member body 121, and a sixth groove 125 is provided on the top of the second clamping member body 121. The size of the sixth groove 125 is the same as that of the third groove 122.

[0027] In this embodiment, by providing the fifth grooves 124 on both sides of the second clamping member body 121, it is convenient for fingers to act on the second clamping member body 121, thereby facilitating the installation and disassembly of the second clamping member body 121.

[0028] Preferably, the number of the cable second clamping members 12 is several, and each cable second clamping member 12 is stacked by mortise and tenon connection.

[0029] In this embodiment, by providing several cable second clamping members 12, the vertical expansion of the cable pillow can be realized, so that the cable pillow has good adaptability and versatility.

[0030] Preferably, arc grooves 114 are provided on both sides of the bottom of the first clamping member body 111.

[0031] In this embodiment, by providing the arc grooves 114 on both sides of the bottom of the first clamping member body 111, it is convenient for fingers to act on the first clamping member body 111, thereby facilitating the installation and disassembly of the first clamping member body 111.

[0032] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
