Abstract

The utility model relates to a wiring slot for electric wires, which is provided with a metal slot body and a slot cover, wherein, both sides of the slot body are provided with longitudinally sunk clamping grooves, and both sides of the slot cover are provided with longitudinally convex clamping strips which can be embedded in the clamping grooves for mutual fixation correspondingly. The wiring slot for electric wires has the advantages of fire resistance, no fire danger, low cost and convenient operation.

Description

A kind of electric wire wire casing

The utility model relates to the wire casing that is used for indoor electric wire arrangement.Particularly a kind of metal wire casing.

Indoor cotton covered wire is extensive use of a kind of difficult combustion cable in plastics groove.Difficult combustion plastics are not fire, incendivity still under the naked light hot conditions, and, hinder the fire-fighting relief in case burning can produce toxic gas.That is, use difficult combustion wire casing still to have hidden fire-fighting danger.The cost of difficult combustion plastics wire casing is also higher.

The purpose of the utility model is to provide a kind ofly not burn the metal cords wire casing that cost is low and easy to use.

Wiring duct described in the utility model, cell body that is made of metal and groove lid are formed, and there is the draw-in groove of vertical depression the cell body both sides, and there is the card article of vertical protrusion groove lid both sides, and card article can embed and make cell body and groove lid relative fixed in the draw-in groove.

Wiring duct described in the utility model adopts metal to make, and does not burn no hidden fire-fighting danger.Cell body and groove cover vertically recessed or protruding draw-in groove or card article, and this vertically concavo-convex effect with reinforcement makes it the cell body made with thin metal blank very, and the groove lid also has rigidity preferably.Because of using very thin plate stamping moulding thereby its cost low.When the groove lid fastens with cell body, only need slightly exert pressure, cell body and groove lid all can produce strain in a small amount, and card article is embedded in the draw-in groove, fasten closely and use easily.

Embodiment one

There is the draw-in groove 1a of vertical depression cell body 1 both sides, and groove covers 2 both sides has the card article 2a card article of vertical protrusion to embed in the draw-in groove.Cell body 1 degree face has one or more to projecting inward reinforcement 3.

Embodiment two

The edge bending of groove lid 2 constitutes the card article 2a that protrudes, and the side of cell body 1 is having inwardly sunken step 1b, and projection that the edge of cell body 1 is bent to form and step constitute draw-in groove 1a jointly.All the other are identical with embodiment one.
