Abstract
The utility model discloses a socket structure of a PP (propene polymer) hush pipe fitting, which comprises a PP hush pipe body, wherein annular bosses integrated with the PP hush pipe body are arranged at the two ends of the PP hush pipe body respectively; annular grooves are formed in an internal wall of the PP hush pipe body corresponding to the annular bosses; rubber rings are matched and mounted in the annular groove; and an inward-convex annular socket step is arranged in the middle of the interior of the PP hush pipe body. The socket structure is reasonable in structural design and adopts the hush pipe fitting connected by a sealing ring, so that the socket structure is free from water leakage in a using process; the strength of a product is good; the height of the step is equivalent to the thickness of pipes; the hush effect is good; the expansion and contraction of the product can be controlled; and operational requirements are met.
Description
Technical field
The utility model relates to the hush pipe field, relates in particular to a kind of PP sound deadening pipe fitting bellmouth structure.
Background technique
Traditional sound deadening pipe fitting connection is glue and connects, and it connects simple, and is insecure, water leakage phenomenon can occur after the long-term use, and product strength is poor simultaneously, in use can stretch, and affects erasure effect.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of PP sound deadening pipe fitting bellmouth structure is provided, its reasonable in design, the sound deadening pipe fitting that adopts seal ring to connect, make can not occur in its using process leaking, product strength is good simultaneously, and its shoulder height is suitable with tubing thickness, can not affect product erasure effect, control simultaneously product flexible.
The utility model is achieved through the following technical solutions:
A kind of PP sound deadening pipe fitting bellmouth structure, include PP hush pipe body, the two ends of described PP hush pipe body are respectively equipped with the annular boss with its one, be respectively equipped with annular groove on PP hush pipe inboard wall of tube body corresponding to described annular boss, cooperate in the described annular groove cushion rubber is installed, the middle part in the described PP hush pipe body is provided with to projecting inward annular socket step.
Described cushion rubber matches with annular groove, and its material is silica gel, the bottom land snug fit of outer surface and annular groove, and its internal surface is concordant with PP hush pipe inboard wall of tube body.
The height of described its step of annular socket step is identical with tubing thickness.
Its principle is: the material of described cushion rubber is silica gel, and predominant use is sealed tube and pipe fitting, makes can not occur in its using process leaking; Middle part in the described PP hush pipe body is provided with to projecting inward annular socket step, kept product strength, and its shoulder height is suitable with tubing thickness, makes it can not affect product erasure effect, has controlled product flexible.
The utility model has the advantages that:
The utility model reasonable in design, the sound deadening pipe fitting that adopts seal ring to connect makes can not occur in its using process leaking, and product strength is good simultaneously, and its shoulder height is suitable with tubing thickness, and good muffling effect is controlled product flexible simultaneously, has satisfied usage requirement.
