Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a flexible suspended cable tray. Background Technology

[0002] Cable trays are rigid structures used to support and protect cables. The most common type is the trough-type cable tray, which is usually made of stainless steel or aluminum alloy and is suspended from the ceiling or electromechanical pipeline support frame.

[0003] Most commonly available suspended cable trays on the market are similar in overall structure, with aluminum alloy or stainless steel troughs as the main body and lugs on the sides for connecting hangers. In actual use, they have some functional shortcomings and room for improvement. For example, in corner areas, right-angled cable trays are usually required. When the corner angle is greater than or less than 90 degrees, a trough with a corresponding angle needs to be customized. This results in poor flexibility and additional costs, as they do not have the function of bending at corners.

[0004] Now, a novel flexible suspended cable tray is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flexible suspended cable tray to solve the problem mentioned in the background art of not having the function of bending and turning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible suspended cable tray, comprising two sets of main tray troughs, with two sets of suspension screws mounted above the main tray troughs, and locking nuts fitted onto the bottom ends of the suspension screws. A fixing plate is fixedly connected to the middle position of the bottom end of the main tray trough, and multiple sets of plastic wire clamps are fixedly connected to the top of the fixing plate. The plastic wire clamps have three sets of cable clamp holes inside. A concave base is fitted onto the bottom end of the main tray trough, and perforated positioning plates are welded to the top of the front and rear ends of the concave base. Limiting strips are welded to the top of the front and rear ends of the main tray trough, and multiple limiting holes are opened inside the limiting strips. A bending assembly that can be bent and rotate is provided between the two sets of main tray troughs.

[0007] The bending assembly includes two sets of connecting end plates, which are fixedly connected to the opposite sides of the two main cable trays. Multiple sets of PVC support plates are provided between the two sets of connecting end plates. The front and rear ends of the PVC support plates are respectively glued with telescopic cavities, and the bottom end of the PVC support plates is glued with nylon fabric.

[0008] As a further technical solution of this utility model, the front and rear sides of the connecting end plate are flush with the front and rear sides of the main channel of the cable tray, and the upper and lower ends of the connecting end plate are flush with the upper and lower ends of the main channel of the cable tray.

[0009] As a further technical solution of this utility model, the top ends of the main channel of the cable tray, the connecting end plate, and the PVC support plate are flush, and the bottom ends of the connecting end plate and the PVC support plate are flush.

[0010] As a further technical solution of this utility model, the bottom end of the telescopic cavity is connected to the top end of the nylon fabric surface, and the bottom end of the nylon fabric surface is flush with the bottom end of the main channel of the cable tray.

[0011] As a further technical solution of this utility model, the plastic wire clip is elastic and the plastic wire clips are arranged at equal intervals.

[0012] As a further technical solution of this utility model, the suspension screw passes through the interior of the perforated positioning piece and the limiting hole, and the limiting hole is arranged at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the flexible suspended cable tray not only realizes the function of bending and turning, but also realizes the function of easy cable fixing, and also realizes the function of adjustable suspension position;

[0014] (1) By setting up connecting end plates, telescopic bellows, nylon cloth and PVC support plates, when in use, the main channel of the cable tray is suspended at the ceiling of the building roof by the suspension screw, and the cable passes through the main channel of the cable tray. In the corner area, when the cable tray needs to turn, the accordion-style connection structure composed of connecting end plates, telescopic bellows, nylon cloth and PVC support plates can be bent directly, and the angle adjustment is more flexible. The inner skeleton composed of connecting end plates and multiple sets of PVC support plates can also protect the cable and support it, realizing the function of bending corners.

[0015] (2) By setting a fixing plate, plastic clamps and cable clips, when in use, the cable passes through the main channel of the cable tray. The plastic clamps can restrict the position of the cable. The cable is pressed in along the opening at the top of the plastic clamp. The three sets of cable clips can hold three sets of cables. The fixing plate is used to fix the plastic clamps, which realizes the function of conveniently fixing the cable.

[0016] (3) By setting a concave base, a perforated positioning plate, a limiting plate, a limiting hole, a suspension screw and a locking nut, when in use, the top of the suspension screw is fixed to the building ceiling. According to the actual installation needs, the position of the concave base is adjusted so that the perforated positioning plate and the appropriate limiting hole on the limiting plate are aligned. Then the suspension screw passes through the limiting hole and the perforated positioning plate, and the locking nut is tightened to complete the installation. Multiple sets of limiting holes allow the suspension position to be flexibly adjusted, realizing the function of adjustable suspension position. Attached Figure Description

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the cable tray needs to bend, the accordion-style connection structure consisting of the connecting end plate 2, the telescopic bellows 3, the nylon fabric 4, and the PVC support plate 5 can be bent directly, and the angle adjustment is relatively flexible. The inner skeleton consisting of the connecting end plate 2 and multiple sets of PVC support plates 5 can also protect the cable and provide support for it.

[0029] A fixing plate 6 is fixedly connected to the middle position of the bottom of the main channel 1 of the cable tray. Multiple sets of plastic wire clips 7 are fixedly connected to the top of the fixing plate 6. The plastic wire clips 7 have three sets of cable clamp holes 8 inside. The plastic wire clips 7 are elastic and are arranged at equal intervals to facilitate wire clamping and securing.

[0030] Specifically, such as Figure 2 and Figure 5 As shown, the plastic cable clamp 7 can restrict the position of the cable. The cable is pressed in along the opening at the top of the plastic cable clamp 7. Three sets of cable clip holes 8 can hold three sets of cables. The fixing plate 6 is used to fix the plastic cable clamp 7.

[0031] A concave base 9 is sleeved at the bottom of the main cable tray 1. Perforated positioning plates 10 are welded to the top of the front and rear ends of the concave base 9.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 6As shown, adjust the position of the concave base 9 so that the perforated positioning piece 10 and the appropriate limiting hole 12 on the limiting plate 11 are aligned. Then, the suspension screw 13 passes through the limiting hole 12 and the perforated positioning piece 10, and the locking nut 14 is tightened to complete the installation. Multiple sets of limiting holes 12 allow the suspension position to be flexibly adjusted.

[0033] Working Principle: In use, the main cable tray 1 is first suspended from the ceiling by the suspension screw 13. Cables pass through the main cable tray 1. At corners, when the cable tray needs to bend, the accordion-style connection structure consisting of the connecting end plate 2, telescopic bellows 3, nylon fabric 4, and PVC support plate 5 allows for direct bending, providing flexibility in angle adjustment. The internal frame formed by the connecting end plate 2 and multiple sets of PVC support plates 5 also protects and supports the cables. As the cables pass through the main cable tray 1, the plastic cable clamps 7 restrict their position. The cables are pressed in through the opening at the top of the plastic cable clamps 7. Three sets of cable clips 8 hold three sets of cables in place. A fixing plate 6 is used to secure the plastic cable clamps 7. The top of the suspension screw 13 is fixed to the building ceiling. According to the actual installation needs, the position of the concave base 9 is adjusted so that the appropriate limiting holes 12 on the perforated positioning piece 10 and the limiting strip 11 are aligned. Then, the suspension screw 13 passes through the limiting holes 12 and the perforated positioning piece 10, and the locking nut 14 is tightened to complete the installation. Multiple sets of limiting holes 12 allow the suspension position to be flexibly adjusted.
