Abstract
The utility model relates to a connecting piece for plastic pipeline, which comprises a connecting piece main body and a sealing cover. Internal wall of end port for the connecting piece is provided with a protruding platform. The connecting piece main body and the sealing cover are in a screw connection. The utility model is characterized in that: the protruding platform on the internal wall of the end port for the connecting piece main body is provided with an O-shaped elastic sealing circle which is supported against by the cushion ring. The sealing cover is internally provided with an open clip supported by the cushion ring, which can sleeve the locked tube piece and cooperated with the locked tube piece. The utility model has the advantages that: 1. good sealing property, 2. good effect in preventing the locked tube piece falling down.
Description
The utility model belongs to link, particularly a kind of plastic pipe link.
The utility model is to design through improving on the basis of ZL91200437.1.In the former technological scheme, the pipe fitting that is locked inserts in the connected link, is threaded sealing cover and be locked and be added with leak-proof gasket between pipe fitting and link with connector main body by its sealing cover.This link sealing is poor, and the pipe fitting that is locked is easy and link comes off.
The purpose of this utility model is that the deficiency of former patented technology is improved, and a kind of good airproof performance is provided, and the plastic pipe link of the pipe fitting difficult drop-off that is locked is to overcome above-mentioned deficiency.
The technical solution of the utility model is: the boss of connector main body port inner wall is provided with the O type elastic seal ring that is compressed by packing ring, but be provided with in the sealing cover suit that supports by packing ring be locked pipe fitting and with the opening clip of its interference fit.
Said clip outer wall is an arc surface.
The connecting part of said packing ring and clip is provided with supporting oblique surface.
The utility model has the advantages that: 1, good airproof performance, 2, the pipe fitting difficult drop-off is locked.
Further specify the utility model with drawings and Examples below.
Accompanying drawing 1 is the utility model structural representation.
Among the figure: 1 is clip, and 2 is packing ring, and 3 is seal ring, and 4 is the elbow main body, and 5 is sealing cover.
Embodiment: as shown in Figure 1, a kind of plastic pipe link is an elbow, elbow main body 4 port inner walls are provided with boss, boss is provided with the O type elastic seal ring 3 that is compressed by packing ring 2, being provided with outer wall in the sealing cover 5 is the opening clip 1 of arc surface, this clip 1 and sealing cover 5 interference fit, and packing ring 2 is provided with supporting oblique surface with the connecting part of clip 1, elbow main body 4 is threaded with sealing cover 5, can lock the pipe fitting that is locked by sealing cover 5 and elbow main body 4 and opening clip 1.The packing ring 2 of support openings clip 1 compresses O type elastic seal ring 3 simultaneously, and good horizontal and longitudinal sealing is effective.
