An energy-saving polymer corrosion-resistant cable tray

Abstract

An energy-saving polymer corrosion-resistant cable tray, which relates to the technical field of polymer cable trays. The present invention provides a first connection block, a second connection block, a third connection block, a fourth connection block and a base on the housing, and the first The first connecting block, the second connecting block, the third connecting block and the fourth connecting block are all equipped with rainproof devices, and the connection between the shell and the first connecting block, the second connecting block, the third connecting block and the fourth connecting block There is a connecting rod on the top, a fixed column on the connecting rod, a bearing on the fixed column, and a pulley on the bearing, so as to achieve the purpose of pulling the wire and preventing the rain. The invention has a reasonable and practical structure and is easy to use, preventing the The rainwater flows into the cable tray, and the cable is better fixed, which not only facilitates the pulling of the cable, but also protects the cable and increases the service life of the cable.

Description

technical field [0001] The invention relates to the technical field of polymer cable bridges, in particular to an energy-saving polymer corrosion-resistant cable bridge. Background technique [0002] It is known that the cable bridge has the advantages of convenient maintenance, convenient installation, safety and reliability in the layout of the power network. More and more buildings use cable bridges in the layout of various circuit cables and power supply networks of equipment. , the corner of the cable tray is connected with the bridge connector, but the current cable tray at the turn has too much friction when threading, and it is inconvenient to pull. The turn of the cable tray is easy to wear the cable skin, which not only cannot protect the cable At the same time, a lot of cables are wasted. In addition, due to the influence of the turning of the cable bridge, it is very laborious to pull the cables, which increases the labor intensity and labor time of the staff. At...

[0002] It is known that the cable bridge has the advantages of convenient maintenance, convenient installation, safety and reliability in the layout of the power network. More and more buildings use cable bridges in the layout of various circuit cables and power supply networks of equipment. , the corner of the cable tray is connected with the bridge connector, but the current cable tray at the turn has too much friction when threading, and it is inconvenient to pull. The turn of the cable tray is easy to wear the cable skin, which not only cannot protect the cable At the same time, a lot of cables are wasted. In addition, due to the influence of the turning of the cable bridge, it is very laborious to pull the cables, which increases the labor intensity and labor time of the staff. At the same time, the rainwater will flow along the cables in rainy days. Flow down into the cable tray, or even flow into the circuit box, causing unnecessary losses
