Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Explanation is in advance, and Fig. 1 illustrates two embodiments one of the present utility model, but two embodiments' one body 1 is a part and imperfect structure.
As shown in Figure 1, embodiment one of the present utility model comprises body 1, is positioned at first mouth of pipe 101 and second mouth of pipe 102 at body 1 two ends.Such as Fig. 1 and Fig. 2, the outer wall 10 of body 1 is provided with the stiffening rib 11 that extends 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 of connection strengthening 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 extending 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.
