Shape boss, the outer tube body are sheathed on the inside of the perforation of the square boss, the square boss and the outer tube
Body by integral forming, the angle of the square boss are provided with interior rounding, and the end of the outer tube body is provided with hollow circular reinforcement
Block, the outer tube body are sheathed on the inside of the perforation of set circular boss, the circular boss and outer tube body one
Shaping.
Preferably, when the outer tube body is provided with square boss described in polylith, along institute between the square boss
The circulating direction for stating outer tube body is placed equidistant.
Preferably, when the outer tube body is provided with circular boss described in polylith, along institute between the circular boss
The circulating direction for stating outer tube body is placed equidistant.
Preferably, the section of the square boss is square, the outer tube body is sheathed on the square boss
Central hole inside.
Preferably, the outer tube body is sheathed on the inside of the central hole of the circular boss.
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：Double-walled protection pipe is made by increasing the body provided with boss 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 steady simultaneously
It is fixed to place, 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 4, a kind of double-walled protection pipe, including interior tube body 1 and be arranged on interior tube body outer surface outer tube
The section of body 2, said inner tube body 1 and the outer tube body 2 is circle, and said inner tube body 1 and the outer tube body 2 are integrally formed, institute
State outer tube body 2 and be provided with hollow square boss 21, the outer tube body 2 is sheathed on the interior of the perforation of the square boss 21
Portion, the square boss 21 are integrally formed with the outer tube body 2, and the angle of the square boss 21 is provided with interior rounding 22,
The end of the outer tube body 2 is provided with hollow circular boss 23, and the outer tube body 2 is sheathed on wearing for set circular boss 23
The inside in hole, the circular boss 23 are integrally formed with the outer tube body 2.The ring stiffness of double-walled construction enhancing body and resistance to compression
Ability, while hollow square boss 21 is set on the surface of outer tube body 2, add adding around pipe shaft equivalent to for body
Strengthening tendons, the ring stiffness and anti-pressure ability of body are enhanced, effectively prevent protection pipe when buried because pressure bursts.Square boss
21 angle is provided with interior rounding 22, and buried often can combine a plurality of protection pipe stacks, and on the one hand interior fillet can be used for
Positioning, it is ensured that stacked between protection pipe neatly, the through hole passed through for mini-cable can be formed by the other hand stacking rear fillet, rationally
It make use of space.The end of body needs to be used to plug into, and circular interface is more suitable for plugging into, therefore the boss of end is designed
For circle.
In the present embodiment, when the outer tube body 2 is provided with square boss 21 described in polylith, the square boss 21
Between be placed equidistant along the circulating direction of the outer tube body 2.Being placed equidistant square boss 21 enables to outer tube body 2 is overall to bear
Pressure it is uniform, prevent the stress of outer tube body 2 most strength burst.
In the present embodiment, when the outer tube body 2 is provided with circular boss 23 described in polylith, the circular boss 23
Between be placed equidistant along the circulating direction of the outer tube body 2.Being placed equidistant circular boss 23 enables to outer tube body 2 is overall to bear
Pressure it is uniform, prevent the stress of outer tube body 2 most strength burst.
In the present embodiment, the section of the square boss 21 is square, the outer tube body 2 be sheathed on it is described square plus
The inside of the central hole of strong block 21.The isometric reinforcement block structure in four sides causes boss entirety uniform force, while described outer
Body 2 is sheathed on the inside of the central hole of the square boss 21 so that the reinforcement degree that the excircle of outer tube body 2 obtains
It is identical, effectively prevent outer tube body 2 from being burst because of unbalance stress.
In the present embodiment, the outer tube body 2 is sheathed on the inside of the central hole of the circular boss 23 so that outer tube
The reinforcement degree that the excircle of the end of body 2 obtains is identical, effectively prevents outer tube body 2 from being burst because of unbalance stress.
