Description
Technical field
Protection pipe technical field is the utility model is related to, refers in particular to a kind of fixable type double-walled protection pipe.
Background technology
Cable and communications optical cable usually require to be put into carried out again in protection pipe it is buried.Currently used protection pipe have straight tube and
Bellows.Straight tube is using the ring stiffness and anti-pressure ability for thickening tube wall reinforced pipe body, but tubing is heavier, causes tubing cost and fortune
Defeated cost is higher.The tube wall of bellows is thin so tubing is lighter, but rigidity and anti-pressure ability far away from straight tube and service life it is short.
Two kinds of tubing all need additional pipe pillow to add material cost to stablize body when in use.
The content of the invention
The utility model provides a kind of relatively strong ring stiffness, lighter in weight for problem of the prior art and need not additionally set
The fixable type double-walled protection pipe of pipe pillow.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
A kind of fixable type double-walled protection pipe, including interior tube body and be arranged on interior tube body outer surface outer tube body, it is described
Interior tube body and the outer tube body by integral forming, said inner tube body are that section is circular straight tube, and the outer surface of the outer tube body is set
There is the first ripple, first ripple includes that section is square primary peak and section is the first circular trough, and described the
The angle of one crest is provided with interior rounding, and the outer surface of the end of the outer tube body is provided with the second ripple, and second ripple includes
Section is the secondary peak of circle and section is the second circular trough.
Preferably, the section of the primary peak is square.
Preferably, the edge of the primary peak is provided with pin-and-hole, the pin-and-hole is provided with barrel bolt.
Preferably, the inwall of said inner tube body is provided with smooth layer.
Preferably, the inwall of said inner tube body is provided with refractory layer.
Preferably, the outer surface of the outer tube body is provided with acid-resistant layer.
The beneficial effects of the utility model：The side that double-walled protection pipe is made by increasing square corrugated pipe outside straight tube
Method so that tubing has preferable ring stiffness and anti-pressure ability in the case of lighter in weight.Body itself can be stablized and put simultaneously
Put, rested the head on without optional equipment pipe, reduce material cost.

Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and accompanying drawing further
Explanation, the content that embodiment refers to not to restriction of the present utility model.The utility model is carried out below in conjunction with accompanying drawing
Detailed description.
As shown in Figures 1 to 6, a kind of fixable type double-walled protection pipe, including interior tube body 1 and it is arranged on the outer of interior tube body 1
The outer tube body 2 on surface, said inner tube body 1 are integrally formed with the outer tube body 2, and said inner tube body 1 is that section is circular straight tube,
The outer surface of the outer tube body 2 is provided with the first ripple 21, and first ripple 21 is the square He of primary peak 211 including section
Section is the first circular trough 212, and the angle of the primary peak 211 is provided with interior rounding 23, the end of the outer tube body 2
Outer surface is provided with the second ripple 22, and it is circular that second ripple 22, which includes the secondary peak 221 that section is circle and section,
Second trough 222.Double-walled construction strengthens the ring stiffness and anti-pressure ability of body, while is in the outer surface of outer tube body setting section
Square primary peak 211 and section are the first circular trough 212, and square crest adds circular tube equivalent to for body
The reinforcement of body, the ring stiffness and anti-pressure ability of body are enhanced, effectively prevent protection pipe when buried because pressure bursts, it is circular
Trough one side section girth it is shorter with respect to for the girth of square-section thus consumptive material be less able to mitigate tubing weight
Amount, on the other hand the shape of no corner angle electric wire of being more convenient for pass through.The angle of primary peak 211 is provided with interior rounding 23, when buried
A plurality of protection pipe can often be combined and stacked, on the one hand interior fillet can be used for positioning, it is ensured that stacked between protection pipe neatly,
On the other hand the through hole passed through for mini-cable can be formed by stacking rear fillet, rationally make use of space.The end of body needs to use
In plugging into, circular interface is more suitable for plugging into, and in the case of pipe thickness identical set ripple can strengthen body ring it is firm
Degree, therefore in the end set section of outer tube body it is circular secondary peak 221 and section is the second circular trough 222.
In the present embodiment, the section of the primary peak 211 is square.Square causes 211 overall stress of crest more
Uniformly, more preferable resistance to compression effect is played.
In the present embodiment, the edge of the primary peak 211 is provided with pin-and-hole 3, and the pin-and-hole 3 is provided with barrel bolt 31.When buried
It is generally necessary to bury a plurality of protection pipe simultaneously, make it that protection pipe will not phase when combination stacks using the pin-and-hole 3 of pluggable barrel bolt 31
To displacement, more neat appearance.
In the present embodiment, the inwall of said inner tube body 1 is provided with smooth layer 4.Smooth inwall effectively prevents cable from penetrating guarantor
The insulating barrier on surface is scratched during pillar.
In the present embodiment, the inwall of said inner tube body 1 is provided with refractory layer 5.Cable can generate heat when in use, in interior tube body 1
Inwall be provided with refractory layer 5, prevent protection pipe spontaneous combustion by heating.
In the present embodiment, the outer surface of the outer tube body 2 is provided with acid-resistant layer 6.Protection pipe is used for buried, the acidity in soil
Material can damage body, set acid-resistant layer 6 effectively to protect body.
It is described above, only it is the utility model preferred embodiment, not the utility model is made any formal
Limitation, although the utility model is disclosed as above with preferred embodiment, but is not limited to the utility model, any to be familiar with sheet
Technical professional, do not departing from the range of technical solutions of the utility model, made when using the technology contents of the disclosure above
A little change or the equivalent embodiment for being modified to equivalent variations, as long as being without departing from the content of the technical scheme of the utility model, foundation
The utility model technology refers to any simple modification, equivalent change and modification made to above example, belongs to this practicality
In the range of new technique scheme.
