Abstract

The utility model relates to a novel corrugated pipe joint, comprising a coupling nut arranged on a corrugated pipe body and a sealing ring therein as well as an outer joint coupled with the coupling nut by threads, wherein the inner wall of a port of the coupling nut is a conical surface; a tooth-shaped elastic clamping ring is arranged between the conical surface and the sealing ring and plays a fixing role; and the elastic clamping ring is cone-shaped, the conicity is consistent to that of the port in the coupling nut so as to lead the matching to be more tight and the elastic clamping ring and the port in the coupling nut are sealed further by the sealing ring. The novel corrugated pipe joint is characterized by simple structure, convenient assembly, good fixity, good sealing and the like.

Description

A kind of novel corrugated pipe connector
Technical field
The utility model relates to a kind of pipe fitting joint, especially a kind of novel corrugated pipe connector.
Background technique
Bellows can absorb vibration, compensate for displacement because of its flexibility, and is widely used in especially pipelines such as domestic hot-water, heating system, air-conditioner water system of every field, compensates expanding with heat and contract with cold of pipeline.But because its undulatory excircle, make the fixedly difficulty of joint, the use flange is arranged in the existing technology, also have and use half-round clamping ring to fix, it as the patent No. 2007203033430 Chinese patent, disclosed quick joint of corrugated pipe, bellows passes coupling nut, coupling nut and fittings body scyewed joint, the port of fittings body forms conical surface, and the conical surface of fittings body and the horn mouth of bellows fit, be provided with clamping ring between the bell-mouthed trough place of bellows and the coupling nut, clamping ring is spliced by the semicircular ring of symmetry, and the cross section of clamping ring is a conical surface, and the tapering that the tapering of this conical surface and fittings body port form matches.This structure has easy to assembly, and characteristic of simple structure still, only depends on the cooperation of the conical surface to seal, and makes sealability relatively poor, and snap ring is divided into two semicircles, and precision is difficult to improve.
Summary of the invention
The purpose of this utility model is the novel corrugated pipe connector of a kind of simple in structure, easy to assembly, good airproof performance of design.The technical solution of the utility model is so to realize:
A kind of novel corrugated pipe connector, comprise the coupling nut (1) be located on the bellows body (5) and interior seal ring (3) thereof, socket (2) with coupling nut (1) scyewed joint, inner port at coupling nut (1) is a conical surface, and is provided with a profile of tooth snap ring (4) between this conical surface and the seal ring (3).
As preferably, described profile of tooth snap ring (4) is cone shape.
As preferably, the smallest end diameter of described profile of tooth snap ring (4) is between bellows crest and trough place diameter.
As preferably, the tapering of described profile of tooth snap ring (4) is consistent with the tapering of coupling nut (1) inner port.
The port inner wall of coupling nut (1) is the conical surface in the corrugated pipe connector structure of the utility model design, between this conical surface and seal ring (3), be provided with a profile of tooth snap ring (4), in order to fixation, snap ring (4) is a cone shape, tapering is consistent with the tapering of coupling nut (1) inner port, make cooperation tightr, and by further sealing of seal ring (3).The utlity model has simple in structure, easy to assembly, characteristics such as stationarity is good, good seal.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is structural representations of snap ring in the utility model.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings 1, accompanying drawing 2, a kind of novel corrugated pipe connector, comprise the coupling nut (1) be located on the bellows body (5) and interior seal ring (3) thereof, socket (2) with coupling nut (1) scyewed joint, inner port at coupling nut (1) is a conical surface, and is provided with a profile of tooth snap ring (4) between this conical surface and the seal ring (3).
Described profile of tooth snap ring (4) is cone shape, and tapering is consistent with the tapering of coupling nut (1) inner port.Its smallest end diameter is between bellows crest and trough place diameter.
During assembling, earlier coupling nut (1) is placed on the bellows body (5), then snap ring (4) is placed in the trough place of bellows, again seal ring (3) is installed,, tighten and get final product at last by socket on the scyewed joint (2).

Claims (4)

1. novel corrugated pipe connector, comprise the coupling nut (1) be located on the bellows body (5) and interior seal ring (3) thereof, socket (2) with coupling nut (1) scyewed joint, it is characterized in that being a conical surface, and be provided with a profile of tooth snap ring (4) between this conical surface and the seal ring (3) in the inner port of coupling nut (1).
2. a kind of novel corrugated pipe connector according to claim 1 is characterized in that described profile of tooth snap ring (4) is cone shape.
3. a kind of novel corrugated pipe connector according to claim 1, the smallest end diameter that it is characterized in that described profile of tooth snap ring (4) is between bellows crest and trough place diameter.
4. a kind of novel corrugated pipe connector according to claim 1 and 2 is characterized in that the tapering of described profile of tooth snap ring (4) is consistent with the tapering of coupling nut (1) inner port.
