[0002] In modern buildings, especially indoor environments, the installation of low-voltage power supply lines is fundamental to ensuring the normal operation of various low-voltage devices. Low-voltage systems encompass multiple fields such as communication, security, monitoring, and networking, and the stability and security of their power supply lines directly affect the performance of the entire low-voltage system. Cable trays, as an indispensable component in the installation of low-voltage power supply lines, are mainly used to protect wires, standardize wiring routing, and facilitate wiring management and maintenance. With the continuous improvement of building intelligence, the types and quantities of indoor low-voltage devices are increasing, placing higher demands on the installation of low-voltage power supply lines.

[0003] Traditional cable tray installation structures have gradually revealed some problems in practical applications. For example, traditional cable trays are inadequate in securing wires, which can easily become loose inside the box, affecting the stability and safety of the circuit. In addition, during installation, it is difficult to flexibly adjust the position and fixing method of the cable tray according to actual installation needs, resulting in the cable tray not being firmly connected to the installation foundation such as cable trays, thus affecting the installation quality of the entire low-voltage power supply line. Utility Model Content

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See attached document Figures 1-6 The installation structure of an indoor low-voltage power supply line in this embodiment includes a cable tray 1, a cable tray box 5, and a limiting component 6. The cable tray 1 serves as the main frame of the entire installation structure, providing installation space and a supporting foundation for the cable tray box 5. The cable tray box 5 is used to accommodate and protect the wires. The orderly installation and fixing of the wires are achieved through the cooperation of the cable tray 1, the cable tray box 5, and the limiting component 6.

[0028] See attached document Figure 2 The bottom of the cable tray 1 is fixedly installed with a frame plate 2 on both sides, and a suspension rod 3 is fixedly installed on both sides of the frame plate 2. A U-shaped part 4 is fixedly installed on the top of the suspension rod 3. The U-shaped part 4 has bolt holes. When in use, the bolts are inserted into the bolt holes, and the U-shaped part 4 is installed in the designated position using the bolts. That is, the installation structure of the indoor low-voltage power supply line is installed in the designated position.

[0029] See attached document Figure 5 and Figure 6 Multiple cable tray boxes 5 are provided and arranged in an orderly manner inside the cable tray 1. Adjacent cable tray boxes 5 are fitted together. Each cable tray box 5 includes a lower box body 501 and an upper box body 502, both of which are U-shaped structures. The upper box body 502 and the lower box body 501 are arranged facing each other. A connecting component 503 is provided between the lower box body 501 and the upper box body 502. The connecting component 503 includes insertion holes 5031 opened at the four corners of the lower box body 501. The insertion holes 5031 are vertically arranged. A limiting hole 5032 is provided on the insertion hole 5031, and the insertion hole 5031 and the limiting hole 5032 are vertically arranged. Insertion rods 5033 are fixedly installed at the four corners of the upper box 502. The insertion rods 5033 are adapted to the insertion holes 5031. The insertion rods 5033 are provided with mounting holes. A first spring 5034 is fixedly installed in the mounting holes. A limiting block 5035 adapted to the limiting hole 5032 is slidably connected in the mounting holes, and the limiting block 5035 is fixedly connected to the first spring 5034.

[0030] When connecting the lower box 501 and the upper box 502, the limiting block 5035 is first pressed down so that it retracts into the mounting hole. Then, the insertion rods 5033 at the four corners of the upper box 502 are aligned with the insertion holes 5031 at the four corners of the lower box 501 and inserted. During the insertion process, the inner wall of the insertion hole 5031 obstructs the limiting block 5035, preventing it from popping out. When the limiting block 5035 moves to the position of the limiting hole 5032, under the elastic action of the first spring 5034, the limiting block 5035 is engaged in the limiting hole 5032, thus realizing the connection between the upper box 502 and the lower box 501.

[0031] See attached document Figure 4 The lower box 501 has a receiving seat 504 fixedly installed inside, and the upper box 502 has a second spring 505 fixedly installed inside. The outer end of the second spring 505 has a crimping seat 506 fixedly installed. The facing surfaces of the receiving seat 504 and the crimping seat 506 are both arc-shaped structures. Before connecting the upper box 502 and the lower box 501, the wire is placed on the receiving seat 504 inside the lower box 501. Then the upper box 502 and the lower box 501 are connected. After the upper box 502 and the lower box 501 are connected, under the elastic action of the second spring 505, the crimping seat 506 moves towards the receiving seat 504, thereby fixing the wire between the receiving seat 504 and the crimping seat 506.

[0032] See attached document Figure 3The limiting component 6 is used to limit the cable tray box 5. The limiting component 6 includes a screw 601 that is threaded to both sides of the cable tray 1. A handwheel 602 is fixedly installed at the outer end of the screw 601. When in use, rotating the handwheel 602 can realize the rotation of the screw 601. A step block 603 is fixedly installed at the inner end of the screw 601. A limiting plate 604 is provided on the inner side of the screw 601. A step hole 605 is opened on the limiting plate 604. The screw 601 is rotatably connected to the limiting plate 604 through the step block 603 and the step hole 605. During the rotation of the screw 601, the limiting plate 604 is moved. In actual use, the corresponding number of cable tray boxes 5 are taken according to the number of wires to be installed. The limiting slots are limited by the screw 601, handwheel 602 and limiting plate 604, and the cable tray box 5 is firmly installed on the cable tray 1.

[0033] In the technical solution adopted in this embodiment, the cable tray 1 is fixed at a designated position by the suspension rod 3 and the U-shaped piece 4, providing an installation base for the cable tray box 5. The cable tray box 5 consists of a lower box body 501 and an upper box body 502. The upper and lower box bodies 501 are connected by the connecting component 503. The wires are placed on the receiving seat 504 of the lower box body 501. After connection, the wires are fixed by the elastic action of the second spring 505 through the crimping seat 506. The limiting component 6 limits the cable tray box 5 by the screw 601, the handwheel 602 and the limiting plate 604, ensuring that the cable tray box 5 is firmly installed in the cable tray 1, thereby achieving stable installation of the entire low-voltage power supply line.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
