The invention adopts the injection molding method for integral molding, has simple manufacture and low cost, and is made of PVC material.
As shown in fig. 2, the transverse conduit a comprises a pipe section a-1 with a uniform diameter and a connector pipe section a-2 arranged at one end of the transverse conduit, the pipe section a-1 with the uniform diameter has the same specification as that of a standard PVC20 pipe, the outer diameter of the pipe section a-1 with the uniform diameter is 20mm, the inner diameter of the connector pipe section a-2 is 20mm, the lowest pipe walls of the pipe section a-1 with the uniform diameter and the connector pipe section a-2 (i.e. the pipe walls of the opposite surfaces of the transverse conduit a and the longitudinal conduit b) are in the same plane, because the inner diameter of the connector pipe section a-2 is larger than that of the pipe section a-1 with the uniform diameter, the connector pipe section a-2 is transitionally connected to the pipe section a-1 with the uniform diameter through a-3 which is uniform, smooth and gradually contracted (see fig. 1 and fig. 9), the pipe section a-1 with the equal diameter, the connector pipe section a-2 and the transition pipe section structure a-3 form an integrated structure, so that the lowest pipe wall of the whole transverse pipe a (namely the pipe wall of the opposite surface of the intersection surface of the transverse pipe a and the longitudinal pipe b) is in the same plane, namely the pipe section a-1 with the equal diameter, the connector pipe section a-2 and the lowest pipe wall of the transition pipe section structure a-3 are in the same plane. A circle of bosses a-4 are arranged on the inner walls of the connector pipe sections a-2, the distance from the bosses a-4 to the ports of the connector pipe sections is 20mm, and the bosses a-4 play a positioning role and are used for limiting the positions of the pipe sections inserted into the connector pipe sections a-2; in use, the interface section a-2 is used to connect standard PVC20 tubing on the one hand and a plurality of cross-connector cells can be combined on the other hand, see figure 10: the pipe section a-1 with the same diameter of the transverse pipe a of one cross device unit is inserted into the connector pipe section a-2 of the transverse pipe a of the other cross device unit, the transverse pipe a of a plurality of cross device units are spliced into a whole along a straight line, and a structure that a plurality of longitudinal pipe and the integral transverse pipe spliced along the straight line are staggered transversely and longitudinally is formed, so that the crossing condition of a plurality of PVC40 pipes and a PVC20 pipe is facilitated, and the requirement of the minimum crossing distance is met.
