Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a complex combined high-interference-resistant low-voltage cable tray. Background Technology

[0002] In the installation and wiring process of low-voltage system engineering, low-voltage cable trays serve as the support and protection carrier for cables. Their installation stability, anti-interference ability, and flexible adaptability directly affect the operational reliability and subsequent maintenance efficiency of the entire low-voltage system.

[0003] Most low-voltage cable trays on the market today adopt a single structural design, which lacks flexibility in installation and adjustment. Traditional low-voltage cable trays are usually connected to the wall or ceiling through fixed brackets. The brackets are installed first, and the height of the cable tray needs to be adjusted later according to the cable laying requirements. Adjusting the height of the cable tray requires repeated adjustment of the positioning bolts. This method is cumbersome and difficult to adapt to the wiring adjustment requirements in complex scenarios. Therefore, a complex combined high-interference low-voltage cable tray is proposed.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0025] Example:

[0026] like Figures 1-6 As shown, this utility model provides a complex combined high-interference weak current cable tray, including tie rods 1, two sets of tie rods 1 are arranged in parallel, and a truss 2 is installed between the bottom of the two sets of tie rods 1. The truss 2 includes a truss body 21, a docking groove 22, a fixing screw hole 23 and a positioning component 24. The truss body 21 has docking grooves 22 at both ends and fixing screw holes 23 at both ends. The positioning component 24 is fixed inside the truss body 21 through the fixing screw hole 23. The tie rods 1 pass through the positioning component 24 and form an insertion connection with the positioning component 24. The truss body 21 maintains a fixed connection position with the tie rods 1. The cable tray 3 is erected on the surface of the truss body 21.

[0027] The tie rod 1 includes a tie rod body 11 and a fixing groove 12;

[0028] The top of the tie rod body 11 is connected to the external suspension. Several sets of fixing slots 12 are provided. The several sets of fixing slots 12 are arranged at equal intervals on one side of the tie rod body 11. The side of the fixing slot 12 is inclined. The fixing slot 12 provides several connection points for the positioning component 24, so that the positioning component 24 can have more fixing points.

[0029] The width of the docking groove 22 is the same as the width of the tie rod body 11. The docking groove 22 provides sufficient space for the tie rod body 11 to pass through. The docking groove 22 and the fixing screw hole 23 are both located at the middle position of the bottom of the truss body 21. The fixing screw hole 23 provides more points for the setting of the positioning component 24, so that the setting position of the positioning component 24 can be adapted to the setting position of the tie rod body 11.

[0030] Several sets of fixing screw holes 23 are provided. The bottom of the positioning component 24 is provided with screw holes that cooperate with the fixing screw holes 23. The positioning component 24 is fixed in the truss body 21 by bolts and the threaded connection of the fixing screw holes 23. When the positioning component 24 is nested with the fixing groove 12, the truss body 21 maintains the connection relationship with the tie rod body 11 under the support of the positioning component 24. At this time, the truss body 21 is held in the set position.

[0031] Positioning assembly 24 includes a lever positioning box 241, a locking tongue 242, and a spring 243;

[0032] Both the locking tongue 242 and the spring 243 are located inside the pull rod positioning box 241. One end of the locking tongue 242 extends out from the inside of the pull rod positioning box 241, and both ends of the spring 243 are connected to the inner wall of the pull rod positioning box 241 and the other end of the locking tongue 242, respectively. The pull rod positioning box 241 serves to limit the insertion of the pull rod body 11, keeping the relative position of the pull rod positioning box 241 and the pull rod body 11 fixed. The end of the locking tongue 242 is inclined to cooperate with the fixing groove 12. The end of the locking tongue 242 is rounded. Under the elastic force of the spring 243, when the locking tongue 242 is aligned with the fixing groove 12, the spring 243 pushes the locking tongue 242 to pop out from the inside of the pull rod positioning box 241. The popped-out locking tongue 242 is embedded in the pull rod positioning box 241. At this time, the locking tongue 242 and the fixing groove 12 form a nested connection. During the upward pushing of the truss body 21, the locking tongue 242 repeatedly retracts and pops out until it reaches the preset position and stops.

[0033] The positioning assembly 24 also includes a limiting screw 244, which is threaded into the inside of the pull rod positioning box 241. After the locking tongue 242 is fully embedded into the fixing groove 12, the limiting screw 244 can be rotated to move laterally through the threaded connection with the pull rod positioning box 241. The end of the laterally moving limiting screw 244 abuts against the locking tongue 242. Under the limiting action of the limiting screw 244, the locking tongue 242 cannot retract into the pull rod positioning box 241, thereby ensuring the stability of the nested connection between the locking tongue 242 and the fixing groove 12.

[0034] In use: Arrange each set of tie rods 1 in sequence. According to the arrangement of tie rods 1, adjust the setting position of positioning component 24 in the truss body 21 and connect it through fixing screw hole 23 and fixing bolt. Align tie rod 1 with tie rod positioning box 241 and insert it. Under the elastic force of spring 243, when locking tongue 242 is aligned with fixing groove 12, spring 243 pushes locking tongue 242 to pop out from inside tie rod positioning box 241. The popped-out locking tongue 242 is embedded in tie rod positioning box 241. At this time, locking tongue 242 and fixing groove 12 form a nested connection. During the upward pushing of truss body 21, locking tongue 242 repeatedly retracts and pops out until it reaches the preset position and then stops pushing truss body 21.

[0035] The above are merely preferred embodiments of this utility model and are illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of this utility model, all of which will fall within the protection scope of this utility model.
