Description
Technical field
Protection pipe technical field is the utility model is related to, refers in particular to a kind of single wall 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 rigidity, lighter in weight for problem of the prior art and need not additionally set pipe
The single wall protection pipe of pillow.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
A kind of single wall protection pipe, including body, the section of the body are circle, the body be provided with it is hollow square plus
Strong block, the body are sheathed on the inside of the perforation of the square boss, inner chamber and the body of the square boss
Inside connection, the square boss is integrally formed with the body, and the end of the body is provided with hollow circular strengthen
Block, the body are sheathed on the inside of the perforation of set circular boss, inner chamber and the body of the circular boss
Inside connection, the circular boss are integrally formed with the body.
Preferably, when the body is provided with square boss described in polylith, along described between the square boss
The circulating direction of body is placed equidistant.
Preferably, when the body is provided with circular boss described in polylith, along described between the circular boss
The circulating direction of body is placed equidistant.
Preferably, the section of the square boss is square, the body is sheathed on the square boss
The inside of central hole.
Preferably, the body is sheathed on the inside of the central hole of the circular boss.
Preferably, the angle of the square boss is provided with interior rounding.
Preferably, the inwall of the body is provided with refractory layer.
Preferably, the outer surface of the body is provided with acid-resistant layer.
The beneficial effects of the utility model：Pass through outside body increase boss method so that tubing weight compared with
There are preferable ring stiffness and anti-pressure ability in the case of light.Body itself can be stablized and place simultaneously, be 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 figure 1, a kind of single wall protection pipe, including body 5, the section of the body 5 is circle, and the body 5 is set
There is hollow square boss 1, the body 5 is sheathed on the inside of the square perforation for strengthening 1 piece, the square boss
1 inner chamber is connected with the inside of the body 5, and the square boss 1 is integrally formed with the body 5, the end of the body 5
Portion is provided with hollow circular boss 2, and the body 5 is sheathed on the inside of the perforation of set circular boss 2, and the circle adds
The inner chamber of strong block 2 is connected with the inside of the body 5, and the circular boss 2 is integrally formed with the body 5.In body 5
Surface sets hollow square boss 1, equivalent to the reinforcement added for body 5 around pipe shaft, enhances the ring of body 5
Rigidity and anti-pressure ability, effectively prevent protection pipe when buried because pressure bursts.The end of body 5 needs to be used to plug into, circular
Interface be more suitable for plugging into, therefore the boss of end is designed as circle.
In the present embodiment, when the body 5 is provided with square boss 1 described in polylith, edge between the square boss 1
The circulating direction of the body 5 is placed equidistant.It is equal to be placed equidistant the pressure that square boss 1 enables to body 5 integrally to bear
It is even, prevent the stress of body 5 most strength from bursting.
In the present embodiment, when the body 5 is provided with circular boss 2 described in polylith, edge between the circular boss 2
The circulating direction of the body 5 is placed equidistant.It is equal to be placed equidistant the pressure that circular boss 2 enables to body 5 integrally to bear
It is even, prevent the stress of body 5 most strength from bursting.
In the present embodiment, the section of the square boss 1 is square, and the body 5 is sheathed on the square reinforcement
The inside of the central hole of block 1.The isometric reinforcement block structure in four sides causes boss entirety uniform force, while the body 5
It is sheathed on the inside of the central hole of the square boss 1 so that the reinforcement degree that the excircle of body 5 obtains is identical, has
Effect prevents body 5 from being burst because of unbalance stress.
In the present embodiment, the body 5 is sheathed on the inside of the central hole of the circular boss 2 so that body 5
The reinforcement degree that the excircle of end obtains is identical, effectively prevents body 5 from being burst because of unbalance stress.
In the present embodiment, the angle of the square boss 1 is provided with interior rounding 11.It is buried often can be by a plurality of protection pipe group
Conjunction stacks, and on the one hand interior fillet can be used for positioning, it is ensured that has been stacked between protection pipe neatly, has on the other hand stacked rear fillet
The through hole passed through for mini-cable can be formed, rationally make use of space.
In the present embodiment, the inwall of the body 5 is provided with refractory layer 3.Cable can generate heat when in use, in body 5
Wall is provided with refractory layer 3, prevents protection pipe spontaneous combustion by heating.
In the present embodiment, the outer surface of the body 5 is provided with acid-resistant layer 4.Protection pipe is used for buried, the acid in soil
Matter can damage body 5, set acid-resistant layer 4 effectively to prevent protection pipe is corroded to cause to perforate.
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
