Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further details.
Explanation is in advance, and Fig. 1 illustrates two embodiments of the invention one, but two embodiments' one body 1 is a part and imperfect structure.
As shown in Figure 1, embodiments of the invention one comprise body 1, are positioned at first mouth of pipe 101 and second mouth of pipe 102 at body 1 two ends.As Fig. 1 and Fig. 2, the outer wall 10 of body 1 is provided with the stiffening rib 11 of shape extension in the shape of a spiral.The cross section of stiffening rib 11 is circular arc, and is provided with the supporting rib rib 112 of the outer wall 10 of the top that connects stiffening rib 11 and body 1 in the inside of stiffening rib 11, whereby, in the both sides of supporting rib rib 112, forms two cavitys 111.
In order to strengthen structure, the outer wall 10 of body 1 also is provided with the structural ribs 12 of shape extension in the shape of a spiral, structural ribs 12 and stiffening rib 11 parallel alternate settings, and the sectional area of structural ribs 12 is less than the sectional area of stiffening rib 11.Both increased intensity, economized in raw materials again, weight reduction.
As shown in Figure 1, first mouth of pipe 101 of body 1 is bellmouth, second mouth of pipe 102 of body 1 is for being used for directly inserting the socket of first mouth of pipe 101 of another body 1, second mouth of pipe, 102 interference of one body 1 or transition fit ground insert first mouth of pipe 101 of another body 1, can realize the connection of two adjacent bodys 1.
Similar with embodiment one structure, in embodiments of the invention shown in Figure 5 four, between second mouth of pipe 102 of a body 1 and first mouth of pipe 101 of another body 1, though be direct insertion, need the two superposition section of hot melt, be tightly connected with realization.
As shown in Figure 3, embodiments of the invention two also comprise seal ring 2, first mouth of pipe 101 of body 1 is bellmouth, second mouth of pipe 102 of body 1 is the socket for first mouth of pipe 101 that inserts another body 1, when connecting two bodys 1, second mouth of pipe 102 inserts in first mouth of pipe 101 of another bodys 1, and seal ring 2 liners are between first mouth of pipe 101 of second mouth of pipe 102 of body 1 and another body 1, to increase sealing effect.
As shown in Figure 4, embodiments of the invention three also comprise thermal shrinkable sleeve 3, first mouth of pipe 101 of body 1 is bellmouth, second mouth of pipe 102 of body 1 is the socket for first mouth of pipe 101 that inserts another body 1, when connecting two bodys 1, thermal shrinkable sleeve 3 is sheathed on the connecting part of first mouth of pipe 101 of second mouth of pipe 102 of body 1 and another body 1, and heating makes thermal shrinkable sleeve 3 tighten in the junction of two mouths of pipe then, to increase sealing effect.
To sum up, in order to improve the ring stiffness of wrapped tube, the present invention adopts a kind of arc structure that had not only had good intensity but also saved material.In order further to improve the ring stiffness of entwining tube, between arc structure inside and circular arc, add supporting rib rib and structural ribs simultaneously, make to add the footpath winding reinforcing pipe in the HDPE spigot and socket type under the identical situation of structural walls wall thickness, have bigger ring stiffness.The design of different nozzle structure can be so that connect and add the footpath winding reinforcing pipe in the adjacent HDPE spigot and socket type.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All within the scope of the present invention or the change in being equal to scope of the present invention all be included in the invention.
