SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a plastics inspection shaft branch pipe elbow to solve difficult installation that present plastics inspection shaft elbow exists and guarantee its sealed validity and with the problem of the linking unevenness of inspection shaft base chute.
For realizing the purpose of the utility model, the technical proposal adopted is that: a branch pipe elbow of a plastic inspection well is characterized in that one end of the elbow is a branch pipe connecting end, and the other end of the elbow is a connecting pipe connecting end; the inner circle surface of the elbow of the branch pipe connecting end is in an equal-diameter step-free hole shape, and the outer circle surface of the branch pipe connecting end is provided with at least two ring groove structures; the ring groove structures comprise two ring platforms which are protruded out of the outer circular surface of the branch pipe connecting end and arranged around the circumference, and a ring groove is formed between the two ring platforms.
As a further alternative, one ring platform in one ring groove structure of the at least two ring groove structures is flush with the end face of the branch pipe connecting end.
As a further alternative, the elbow between the branch pipe connection end and the connection pipe connection end is a curved section, and the outer surface of the curved section is provided with a plurality of ribs.
As a further alternative, the ribs are located on the surface of the curved section on the side facing away from the corner.
As a further alternative, the ribs are arranged in the circumferential direction of the curved section.
As a further alternative, the ring groove structure and the elbow are of an integral structure.
The utility model has the advantages that: the inside poroid that is the steplessly of branch connection end of elbow, and set up convex loop wheel at the surface outward, form the annular between two loop wheel ss, so that install the sealing washer in the annular, both avoided the rubbish in the elbow to pile up, the linking roughness with inspection shaft bottom seat chute and the unblocked nature of circulation have been improved, again through convex loop wheel set up satisfied with the orificial adaptation of inspection shaft branch pipe, and elbow weight is suitable, the mounted position of sealing washer has been confirmed simultaneously, high durability and convenient installation, the operation degree of difficulty has been reduced, alone with the elbow facing into in the inspection shaft branch pipe can, the uniformity of installation and sealed validity have been improved, two at least loop wheel structures have also guaranteed and have been connected with between the branch pipe with sealed reliability and stability.
