Water；Cable bearer is installed, cable bearer is usually made by metal material, by welding or being screwed in ditch in cable duct
On wall, service life is not good enough, and after cable usage time is slightly permanent, cable can bend or deform, in this way
It is easy for being formed between cable and kinking, it is cumbersome in repair.
Utility model content
In order to solve the above technical problems, the utility model provide one kind can fireproof, it is with long service life, can prevent
What cable kinked, facilitate the fireproof durable cable duct of repair.
To achieve the above object, the technical solution adopted in the utility model is a kind of fireproof durable cable duct, including embedded
Ditch frame in underground, structural feature are that several cross bars are connected on the side wall of ditch frame, cross bar layering setting, cross bar
It is equipped with arc groove, arc groove is located on the circumferential surface of cross bar, and one end of the cross bar is equipped with bolt shape connecting pole, the ditch
Frame outer patch is equipped with fire-proof plate, and the cross bar is fixedly clamped by connecting pole twist-on on fire-proof plate and by ditch frame, on arc groove
It is combined with the limit buckle that can be inverted upside down, limit buckle is connect with cross bar using screw-driving, the cross bar, ditch frame and fire-proof plate
Aluminium oxide ceramics is all made of to be made.
The section of ditch frame is semicircle as a further improvement of the utility model, and upper cover is connected with above ditch frame.
The section of upper cover and the section of ditch frame form a complete circle as a further improvement of the utility model,
Upper cover is made of corundum.
The quadrangle end on upper lid is equipped with pulley as a further improvement of the utility model,.
Be equipped with the cavity for accommodating upper cover in fire-proof plate as a further improvement of the utility model, the fire-proof plates of both sides it
Between be equipped with sliding rail.
Upper cover is moved on the slide rail by pulley and is equipped between cavity close as a further improvement of the utility model,
Strip of paper used for sealing.
The utility model has the beneficial effects that：Reasonable design, it is simple in structure, there is fire-proof function, can prevent high temperature from firing
The destruction to cable is burnt, and the neat arrangement of cable can be placed and be fixed, when repair, facilitates the opening of upper cover,
Increase working efficiency.
