Background

Electrician's sleeve pipe is widely used in the circuit, plays the guard action to electric wire and cable, and the fire-retardant electrician's sleeve pipe that uses at present is mostly at ordinary sleeve pipe overcoat fire protection coating, and the effect is relatively poor and easily peel off, and common electrician's sleeve pipe shock attenuation resistance to compression effect is relatively poor, and long-time back flame retardant efficiency of using is unstable, can't play the effect of protection to electric wire and cable when high temperature or conflagration take place, and sleeve pipe self easily becomes the fuel that flame burning spreads simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the technical defects exist, and provides a flame-retardant electrical casing, which is provided with a waterproof layer, a first supporting layer, a second supporting layer, a supporting frame sheet, fillers, a partition panel and an outer sheath in a matching way, so that the partition panel and the supporting frame sheet in the shape of a trapezoid wave ring play a role in resisting pressure and damping for the whole electrical casing in use, meanwhile, the trapezoid wave ring and the partition panel which are respectively connected with the first supporting layer and the second supporting layer are radially arranged with equal distances to divide the interior of the electrical casing into a plurality of independent spaces, when the electrical casing meets fire, one outer sheath is burnt and damaged, flame retardant fillers filled in the first supporting layer and the second supporting layer can inhibit flame and retard fire, the flame retardant electrical casing does not spread on the electrical casing, an inner cable generates a protective effect, and the problem that the currently used flame-retardant electrical casing is mostly coated with fireproof paint outside the common casing is solved, the effect is relatively poor and easily peels off, and the shock attenuation resistance to compression effect of the commonly used electrician sleeve is relatively poor, and the flame retardant effect is unstable after long-time use, and the sleeve can not protect the cable when high temperature or fire occurs, and simultaneously can easily become the problem of the fuel that the flame burning spreads.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises a waterproof layer; a first supporting layer is arranged on the outer side of the waterproof layer; a second supporting layer is arranged on the outer side of the first supporting layer; a support frame sheet is arranged between the first support layer and the second support layer; a gap between the first supporting layer and the second supporting layer is filled with a filler; a plurality of partition panels are equidistantly arranged on the radial outer side of the waterproof layer; the partition board and the support frame sheet are arranged at intervals along the axial direction of the waterproof layer; an outer sheath is arranged outside the second supporting layer.

Further optimizing the technical scheme, the support frame sheet is in a shape of a trapezoidal wavy ring; the support frame sheet is in a trapezoidal wave ring shape; the inner side of the support frame sheet is tightly attached to the first support layer; the outer side of the support frame sheet is tightly attached to the second support layer.

Further optimizing the technical scheme, the filler is an aluminum hydroxide flame retardant.

Further optimize this technical scheme, the outside edge of partition panel is relative with the outside edge of second supporting layer.

Compared with the prior art, the utility model has the advantages of it is following: the adoption is provided with the waterproof layer, first supporting layer, the second supporting layer, the support frame piece, the filler, the partition panel, the cooperation of oversheath, realized that in use partition panel and the support frame piece of trapezoidal wave ring shape play resistance to compression absorbing effect to whole electrician's sleeve pipe, simultaneously respectively with first supporting layer, trapezoidal wave ring that the second supporting layer is connected radially is provided with the partition panel with the equidistance and becomes a plurality of independent spaces with electrician's sleeve pipe internal partitioning, when electrician's sleeve pipe meets the fire, be burnt the damage when an oversheath, the fire retardant filler that first supporting layer and the intussuseption of second supporting layer pack the setting can restrain fire-retardant to flame, not stretch on electrician's sleeve pipe, the internal cable produces the protection.
