Description

Bus duct convenient to use

Technical Field

The invention relates to the field of bus ducts, in particular to a bus duct convenient to use.

Background

The bus duct is a closed metal device formed from copper and aluminium bus posts, and is used for distributing large power for every element of dispersion system. Wire and cable have been increasingly replaced in indoor low voltage power transmission mains engineering projects. The bus duct is a novel conductor formed by using copper or aluminum as a conductor, using a non-olefinic insulating support and then being installed in a metal groove. Nowadays, the wiring system is indispensable for electrical equipment and power systems of high-rise buildings, factories, and the like. Because of the need of various building electric power of buildings, factories, etc., and the need has a tendency to increase year by year, the use of the original circuit wiring method, i.e., the pipe-through method, brings many difficulties in construction, and when the power distribution system is to be changed, it is almost impossible to make it simpler, however, if the bus duct is adopted, the purpose can be achieved very easily, and in addition, the building can be more beautiful.

However, when the existing bus duct is used, the wire partition plate in the bus duct is inserted into the square hole of the flame-retardant partition plate, and the wire partition plate and the square hole of the flame-retardant partition plate are just in size and cannot be conveniently inserted into the square hole, so that the bus duct is inconvenient to use and low in use efficiency.

Disclosure of Invention

The invention aims to solve the technical problems that when a bus duct is used, a lead clapboard cannot be well inserted into a square hole of a flame-retardant clapboard, the use efficiency is low, and the bus duct convenient to use is provided to solve the problem that the lead clapboard is inserted into the flame-retardant clapboard.

The invention is realized by the following technical scheme:

bus duct convenient to use, including the bus duct body, this internal fire-retardant baffle and the square hole that runs through that is provided with a plurality of square holes of bus duct, the wire baffle of being connected perpendicularly with fire-retardant baffle, be provided with first standing groove on the fire-retardant baffle between two adjacent square holes, be provided with a plurality of second standing grooves on the first standing groove, be provided with rotatable pulley in the second standing groove, the axis and the fire-retardant baffle place plane of pulley are parallel to each other, and the diameter of pulley is the same with the distance between two adjacent square holes, when the wire baffle inserts the square hole, the side of wire baffle and pulley contacts, the pulley is rotatory under the drive of wire baffle.

Further, this device is when using, during the wire baffle inserts the square hole, because the size of wire baffle is the same with the size of square hole, consequently when inserting, need great strength, also need exert oneself just can be better extract when extracting, this device is provided with first standing groove between with the square hole of necklace, be provided with the pulley in the second standing groove on the first standing groove, consequently when inserting the wire baffle, the side and the pulley of wire baffle contact each other, can be quick convenient slip-in and roll-off, and also can effectually block the wire baffle, and the availability factor is higher.

This device compares with current device, and this device also can be convenient when the maintenance is changed take out the wire baffle, further improvement availability factor to can not influence daily use yet, the long-term use of being more convenient for.

Preferably, the adjacent inner wall of the bus duct convenient to use, which is provided with the pulley on the square hole, is provided with a plurality of convex strips. Be provided with the sand grip on two other sides in square hole, through the further increase frictional force of sand grip, and then can be better fix the wire baffle to can not influence quick convenient taking out.

Furthermore, a heat dissipation layer is arranged above the second placing groove in the flame-retardant partition board, a plurality of through holes are formed in the heat dissipation layer, one ends of the through holes penetrate through the upper end of the flame-retardant partition board, and the other ends of the through holes penetrate through the lower end of the heat dissipation layer and are communicated with the second placing groove; the heat dissipation layer is also arranged below the second placing groove, a plurality of through holes are formed in the heat dissipation layer, one ends of the through holes penetrate through the lower end of the flame-retardant partition plate, and the other ends of the through holes penetrate through the upper end of the heat dissipation layer and are communicated with the second placing groove. The bus duct curb plate is not good because the radiating effect, probably makes the problem of inboard wire burning when the heat is too high, consequently is provided with the through-hole on fire-retardant baffle, through-hole and second standing groove intercommunication, the side intercommunication of second standing groove and square hole, consequently inserts the junction intercommunication of back through-hole and wire baffle and square hole at the wire baffle, consequently can effectually carry out local heat dissipation through the through-hole, improves the circulation of air, and then prevents the high temperature.

Preferably, bus duct convenient to use, the quantity of second standing groove is no less than three in the first standing groove to the axis of the pulley in the second standing groove is on same straight line. On the same straight line, more be favorable to driving the wire baffle and put into, it is higher to put into efficiency, more convenient to use.

Preferably, the rubber layer is arranged on the pulley, and the bus duct is convenient to use. Through rubber layer and wire baffle mutual contact, when the wire baffle removed, it is rotatory to drive the pulley, goes into the back at the wire baffle card, also can fix the wire baffle through the rubber layer, prevents its roll-off, and the availability factor is higher.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. when the bus duct is used, the wire partition plate can be clamped into the square hole more conveniently and rapidly, and can be effectively fixed after being clamped, so that the use is not influenced;

2. the bus duct is convenient to use, the device is convenient to take out quickly, the maintenance and replacement efficiency can be effectively improved, and the bus duct is more convenient to use for a long time;

3. the bus duct is convenient to use, the device is more favorable for heat dissipation, the air flow is increased at the joint of the lead partition plate and the square hole, the heat dissipation can be effectively carried out, the structure of the device is simple, redundant space positions are not increased, and the use efficiency is higher.
