Abstract
The utility model relates to a corrugated pipe connecting piece which comprises corrugated pipes and plastic coating layers coated on the external of the corrugated pipes, wherein one end of each of the corrugated pipes is machined into a flat opening, a hexagonal nut is sleeved on the flat opening, and a blocking hoop is sleeved on a first wave trough outside the flat opening of the corrugated pipe. The utility model provides a connecting mode of stainless steel corrugated pipes with plastic sheathes, overcomes the defects that existing stainless steel corrugated pipes has inconvenient assembly and disassembly and high cost in use, and is easy to accept by consumers. The corrugated pipe connecting piece has high security, and is applicable to the connection and use of corrugated pipelinesof gas, water supply, air-conditioning and the like.
Description
Technical field
The utility model relates to annular corrugated effective link, belongs to ring bellows and connects appliance device field.
Background technique
Because the annular section of bellows is irregular transverse section, conventional connecting means is difficult to connect, and sealing also is difficult to guarantee, becomes the technological difficulties in pipe applications.Existing interconnection technique such as electric smelting tape welding commonly used connect, extrude welding gun welding, shrink belt coating etc., all occur defective in various degree in application, cause the joint to leak, and have restricted the application of this kind tubing.Therefore, need a kind of safe, effective, convenient bellows link that uses.
Summary of the invention
The purpose of this utility model is to overcome the inconvenient drawback of bellows connection construction in the prior art, and a kind of bellows link of improved easy installation and removal is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of bellows link comprises bellows and its outside plastic packets coating that coats, and an end of bellows is processed as flat mouthful, at flat mouthful of place's socket six square nuts of this end; Be socketed with the retaining hoop on flat mouthful of first interior wave trough of bellows.
The utility model compared with prior art provides a kind of simple in structure, easy to operate pipe connecting device, has overcome the installing/dismounting inconvenience and the too high drawback of cost that exist in the existing corrugated stainless steel tubing use, is accepted by the Consumer easily.And safe, be applicable to the connection and the use of aspects such as combustion gas, water supply, air-conditioning corrugated conduit.
Description of drawings
Accompanying drawing is the structural representation of the utility model bellows link.
Among the figure: 1, bellows, 2, the plastic packets coating, 3, six square nuts, 4, the retaining hoop, 5, Ping Kou.
Embodiment
Referring to accompanying drawing, for having the stainless steel ripple connecting tube of plastic sheath, the outside of bellows 1 is surrounded by plastic overmold layer 2, may also be referred to as plastic sheath; One end of bellows 1 is processed as flat mouthful 5, at flat mouthful of 5 places, socket six square nuts 3 of this end; On first wave trough in flat mouthful 5 of the bellows, be socketed with retaining hoop 4.
During enforcement, the end with plastic sheath and bellows is processed into flat mouthful 5 earlier, and the internal diameter of nut 3 bottom surfaces is greater than the outside diameter of bel of band plastic sheath; Then nut 3 is inserted on the bellows that has plastic sheath from flat mouthful 5, will keep off again on first wave trough that hoop 4 is placed on the flat mouth of bellows 5 outsides.Nut 3 is pushed away forward along a flat mouthful direction, make retaining hoop 4 enter nut inboard, the preceding end of shifting onto and get final product; Add sealing gasket, can connect other external accessories.
