The part for stating interval is provided with annular relief.
As an improvement scheme, the sealing ring mounting groove is the annular groove.
As an improvement scheme, the annular groove is arranged concentrically with the body.
As an improvement scheme, the cross sectional shape of the annular relief is triangle.
As an improvement scheme, between the adjacent annular groove at intervals of 0.5mm-1.5mm.
Compared with prior art, the beneficial effects of the utility model are：
The snap joint in hard polyethylene chloride tube road, including body；The both ends open of body, and body is close to wherein one end
Outer wall on offer sealing ring mounting groove, some annular grooves are offered on the inwall of the body other end parallel, and set parallel
The axial length for the groove put is the half of body axial length, is provided with an interval between adjacent annular groove, body it is interior
The part that wall is in interval is provided with annular relief, based on above structure, can be fixed on sealing ring provided with sealing ring mounting groove
In sealing ring mounting groove, polyvinyl chloride pipe is set on body, then snaps into sealing ring installation using two panels groove type clip
The side of groove, the connection of polyvinyl chloride pipe and body can be achieved, leak gas leak phenomenon is not present after tightening, improve work effect
Rate, some annular grooves are offered parallel on the inwall of the body other end, the part is using necking machine by the polyvinyl chloride pipe mouth of pipe
Reduced, be then sleeved in body, annular relief is in contact with the tube wall of polyvinyl chloride pipe, ensure that body and polychlorostyrene
The sealing and fastness of ethylene tube connection.
Sealing ring mounting groove is annular groove, reasonable in design based on above structure, convenient to install sealing ring.
Annular groove is arranged concentrically with body, reasonable in design based on above structure, improves inboard wall of tube body and polyvinyl chloride
The sealing of pipe connection.
The cross sectional shape of annular relief is triangle, reasonable in design based on above structure, convenient installation.
Between adjacent annular groove at intervals of 0.5mm-1.5mm, it is reasonable in design based on above structure, reduce and take
Area.
To sum up, the utility model realizes fast assembling-disassembling and the technique effect of antileaking gas leakage, and the utility model is set
Simple in construction, operational control simplicity is counted, is easy to extensive manufacture and installation, has a wide range of application.
