Abstract
The utility model discloses a fire -retardant electrician's sleeve pipe, including inner tube layer, outer tube layer, the inner tube layer cross section is circular, the outer wall cross section on outer tube layer is the rectangle, and inner wall shape of cross section and inner tube layer cooperate, the inner tube layer surface is equipped with the lug of symmetric distribution, be equipped with the recess with lug matched with on the inner wall, be equipped with the strengthening rib between outer wall and the inner wall. The flame retardant efficiency of this tubular product is good, and the rectangle structure is adopted in the outside, and stability is good, easy -to -use when installation, warehousing and transportation, has practiced thrift a large amount of time and cost. Simultaneously, the detachable connection in layer of the inside and outside pipe of tubular product because the damage is the outer tube layer usually, consequently, during the maintenance, seems simple more and saves the cost.
Description
Technical field
This utility model relates to a kind of tubing, specifically refers to a kind of flame-retardant electric casing.
Background technology
At present, pvc pipe and being widely used in life and commercial production, and progressively
Replace the status of steel pipe.But still using cross section due to pvc pipe is circular pipe
Material so that pvc pipe is in daily transport and deposits, so when installing, it is required to use
Fixed support, otherwise, what PVC cannot be stable prevents, and is easily just affecting PVC
Chang Gongneng, the most easily damages tubing.
Utility model content
The purpose of this utility model is to provide for a kind of flame-retardant electric casing, and this sleeve pipe is fire-retardant
Effective, good stability when installation, accumulating, it is not necessary to optional equipment fixed support, greatly
Having saved greatly cost, it is the most convenient to use.
In order to achieve the above object, this utility model provides following technical scheme: one hinders
Combustion electrical casing pipe, including interior tube layer, external tube layer, said inner tube layer cross section is circular,
The external wall cross-section of described external tube layer is rectangle, and cross section of inboard wall shape matches with interior tube layer
Close, said inner tube layer outer surface is provided with symmetrical lug, described inwall be provided with
The groove that lug matches, is provided with reinforcement between outer wall and inwall, described reinforcement it
Between be filled with fire proofing.
It is further preferred that described lug prolongs interior tube layer axial distribution.
It is further preferred that be provided with fixing port outside described external tube layer.
It is connected it is further preferred that said inner tube layer is detachable with external tube layer.
The beneficial effects of the utility model: this tubing has preferable flame retardant effect, and outside
Employing rectangular configuration, good stability when installation, accumulating, easy-to-use, save a large amount of
Time and cost.Meanwhile, the detachable connection of inside and outside tube layer of tubing, due to broken
That damages is typically external tube layer, therefore, during maintenance, it appears simpler and cost-effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Marginal data: 1, interior tube layer；2, external tube layer；3, groove；4, reinforcement；11、
Lug；21, outer wall；22, inwall.
Detailed description of the invention
We combine accompanying drawing and do a kind of flame-retardant electric casing described in the utility model below
Further instruction.
As shown in fig. 1, a kind of flame-retardant electric casing of the present embodiment, including interior tube layer 1,
External tube layer 2, said inner tube layer 1 cross section is circular, the outer wall 21 of described external tube layer 2
Cross section is rectangle, and inwall 22 shape of cross section matches with interior tube layer 1, said inner tube
Layer 1 outer surface is provided with symmetrical lug 11, and described inwall 22 is provided with and lug
The groove 3 that 11 match, is provided with reinforcement 4 between outer wall 21 and inwall 22, described
It is filled with fire proofing between reinforcement 4.For unwrapping wire, transportation flow inside interior tube layer 1
Matter, external tube layer 2 is for preferably providing tubing stability, it is simple to installation, accumulating, interior
Tube layer 1 and external tube layer 2 can carry out separated maintenance, reduce cost, saved manpower.
In the present embodiment, described lug 11 prolongs interior tube layer 1 axial distribution.Be conducive to inner tube
Fixing of layer 1.
In the present embodiment, outside described external tube layer 2, it is provided with fixing port.It is easy to the installation of tubing
Fixing.
In the present embodiment, said inner tube layer 1 is detachable with external tube layer 2 to be connected.It is easy to dimension
Protect, cost-effective.
Protection domain of the present utility model is not limited to above example and conversion thereof.
