Abstract
The utility model discloses a channel joist. The channel joist is a cuboid structure, and comprises an installing plate, and an upper side plate, a lower side plate, a left side plate and a right side plate which are perpendicular to the installing plate. The installing plate is equipped with first installing holes, and the left and right side plates are equipped with second installing holes respectively. When being used, the channel joist of the utility model is fixed at the lower ends of a left channel upright plate and a right channel upright plate, and an insulating plate is added at the upper part; plastic screws are fixed in square nuts from top to bottom, and a vertical bar falls on the insulating plate directly, thereby preventing a copper bar from drooping. Under the premise of realizing the functions of the channel joist, at the aspect of structure, the channel joist of the utility model is small in volume, facilitates saving space, and enables the materials to be saved and the cost to be reduced.
Description
Technical field
The utility model relates to switch cubicle component technology field, relates in particular to a kind of passage joist.
Background technology
The complete cabinet of low-voltage electrical is the equipment of being responsible for completing controlling electric energy, protection, conversion and distribution in low-voltage power supply system.The complete cabinet of low-voltage electrical can be deep into technique scene, public place, residential building, and every place of electrical installation that makes all must be equipped with this series products.
For the passage joist that uses in switch cubicle, under the prerequisite that realizes passage joist function, reduce the volume of passage joist as far as possible, have positive effect for space limited in switch cubicle, and be conducive to save material, reduce costs.
The utility model content
The utility model is exactly to provide a kind of passage joist for the problem that solves above-mentioned prior art existence.
The purpose of this utility model is achieved through the following technical solutions:
A kind of passage joist, described passage joist is rectangular structure, comprises a mounting panel, and perpendicular to side plate up and down, the left side plate of described mounting panel; The first installing hole is set on described mounting panel, the second installing hole is set respectively on described left side plate.
Preferably, described the first installing hole comprises several square fixing holes, and these several square fixing hole is set up in parallel at described mounting panel middle part.
Preferably, described square fixing hole has 5.
Preferably, described the second installing hole comprises two manholes, and described two manholes distribute up and down and are arranged on described left/right side plate.
Preferably, an end of described mounting panel also is provided with the 3rd installing hole, and the 3rd installing hole is a circular port position.
Preferably, described mounting panel, up and down side plate, left side plate are structure as a whole.
Compared with prior art, the utlity model has following beneficial effect:
Passage joist of the present utility model is fixed on passage riser lower end, left and right when using, and top adds insulation board, adopts plastic screw to be fixed on square nut from top downwards, and vertical row directly drops on insulation board, thereby prevents that copper bar is sagging.Under the prerequisite that realizes passage joist function, on structure, passage joist volume of the present utility model is little, is conducive to conserve space, saves material and reduces costs.
