In the utility model preferred embodiment, the cross section in described left support portion is circular arc, and the cross section in described right support portion is triangular in shape.
In the utility model preferred embodiment, described outer tube body, supporting portion and interior tube body are formed in one, and the quantity of described supporting portion is 4.
In the utility model preferred embodiment, described interior tube body and outer tube body are coated with antioxidant layer, described interior tube body internal coat has pickling layer.
In the utility model preferred embodiment, the cross section of described outer tube body and interior tube body is cylindrical.
The beneficial effects of the utility model are: the pneumatic steel cylinder seamless steel pipe of the utility model, can improve the support strength of seamless steel pipe, long service life, structure is simple.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model pneumatic steel cylinder seamless steel pipe one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, outer tube body, and 2, interior tube body, 3, supporting portion.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of pneumatic steel cylinder seamless steel pipe, it is characterized in that, comprise: outer tube body 1, described outer tube body inside is provided with interior tube body 2, and described outer tube body 1 is provided with multiple supporting portion 3, described supporting portion 3 comprises left support portion and right support portion, described left support portion is connected with right support portion, and described left support portion stretches out in outer tube body 1, and right support portion contacts with interior tube body 2.
In addition, the cross section in described left support portion is circular arc, and the cross section in described right support portion is triangular in shape.
In addition, described outer tube body 1, supporting portion 3 and interior tube body are 2 one-body molded, and the quantity of described supporting portion 3 is 4.
In addition, described interior tube body 2 and outer tube body 1 are coated with antioxidant layer, the internal coat of described interior tube body 2 has pickling layer.
In addition, the cross section of described outer tube body 1 and interior tube body 2 is cylindrical.
Be different from prior art, the pneumatic steel cylinder seamless steel pipe of the utility model, can improve the support strength of seamless steel pipe, long service life, structure is simple.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
