Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a cable tray that is easy to disassemble and bendable. Background Technique

[0002] A cable tray is a support structure used for laying electrical circuits. It is mainly used to protect wires, cables, optical cables, etc., and at the same time provides necessary support and guidance to ensure the connection between electrical equipment. Cable trays are widely used in electrical installations in places such as buildings, factories, and data centers. Cable trays play an important role in electrical systems. They not only protect electrical circuits but also improve the safety and reliability of electrical systems. In the working production areas of automated production and numerical control production and other fields, a large number of circuits need to be laid, and cable trays are required for the circuit laying in these areas.

[0003] However, the existing cable trays are modularly assembled. Workers need to erect scaffolding or ladders for high-altitude operations to connect between cable trays. Most cable trays need to be bolted together to ensure stability. When workers perform high-altitude operations to connect cable trays, they not only need to use a variety of tools and parts such as bolts, but also the operation of raising both hands easily causes the center of gravity of the staff to be unstable, increasing the danger of high-altitude operations. At the same time, if there is a height difference on the indoor roof, the height of the cable tray needs to be adjusted. However, most of the existing cable trays are installed in a straight line and cannot be bent arbitrarily, so the applicable range is small. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable tray that is easy to disassemble and bendable, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cable tray that is easy to disassemble and bendable, including a cable tray body and a top cover.

A connecting part for facilitating high-altitude installation and disassembly and bendable cable trays is arranged between the cable tray body and other cable tray bodies;

[0006] Among them, the connecting part includes a bearing, a connecting member, a movable groove, a sliding rod, a sliding block, a push plate, a first telescopic rod, a first anti-disengagement plate, a first spring, a connecting rod, a cross groove, a screwing cap, a cross-shaped clamping block, a second telescopic rod, a second anti-disengagement plate, and a second spring. The bearing penetrates the cable tray body and is rotatably connected to the cable tray body. The side surface of the connecting member is attached to the side surface of the cable tray body.

[0007] Preferably, an activity groove is formed inside the connecting member. A sliding rod penetrates through the inside of the activity groove. The sliding rod is slidably connected to the activity groove. A slider is fixedly connected to the bottom surface of the sliding rod. First, determine the height at which the bridge body needs to be installed to adjust the position between the hoisting member and the suspender. When connecting between the bridge body and other bridge bodies, the staff can directly grasp the connecting member and press the push plate centered, so that the push plate drives the sliding rod to slide in the activity groove through the slider, so that the sliding rod drives the connecting rod to move together. The bottom surface of the slider is fixedly connected with a push plate, and the slider penetrates through the connecting member and is slidably connected.

[0008] Preferably, a first telescopic rod penetrates through the inside of the sliding rod. When directly pulling the bridge body and the connecting member, but at this time the connecting rod is inserted into the bearing, so that the connecting rod is limited, and the connecting member is pulled, when the first telescopic rod extends out of the sliding rod to increase the connecting distance of the connecting member, at the same time the connecting rod can rotate in the bearing to adjust the height difference between the two sides of the bridge body. A first anti-detachment plate is fixedly connected to one end of the first telescopic rod located inside the sliding rod.

[0009] Preferably, the number of the first anti-detachment plates is two groups, and a first spring is fixedly connected between the two groups of the first anti-detachment plates.

[0010] Preferably, a connecting rod is fixedly connected to one end of the first telescopic rod away from the sliding rod. The second spring between the two symmetrically arranged connecting rods will be compressed, and at the same time the second telescopic rod will be retracted into the connecting rod. When the total length of the symmetrically arranged connecting rods is less than the inner width of the bridge body, place the symmetrically arranged connecting rods inside the bridge body. A cross groove is formed on the left side of the connecting rod. A screwing cap penetrates through and is threadedly connected to the left side of the connecting rod. Align the end of the connecting rod with the cross groove and push it into the bearing. Since the connecting rod is made of a ductile insulating material and a cross groove is formed on the surface of the connecting rod, the connecting rod at the end with the cross groove can contract a certain distance in the middle, ensuring that the threaded end of the connecting rod passes through the bearing. A cross clamping block is rotatably connected to the inside of the screwing cap.

[0011] Preferably, a second telescopic rod penetrates through the inside of one end of the connecting rod away from the screwing cap. After the connecting rod passes through the bearing, grasp the screwing cap and align the cross clamping block with the cross groove. Then, when the screwing cap is screwed, the cross clamping block is embedded into the cross groove, and the connecting rod and the screwing cap are tightened to complete the installation. A second anti-detachment plate is fixedly connected to one end of the second telescopic rod located inside the connecting rod.
