Abstract
The utility model discloses a pressing type connector used for connecting large automobile air-conditioning pipes. The pressing type connector comprises a connector body and is characterized in that the tail part (1) of the connector body is sleeved with a rubber tube (2) of an automobile air conditioning pipeline; the rubber tube (2) is sleeved on the tail part (1) of the connector body; a plurality of sealing grooves (3) are formed on the surface of the tail part (1) of the connector body; protrusions (4) are formed on the edges of two sides of each sealing groove (3); sealing parts (6) are arranged in the sealing grooves (3) and positioned between the rubber tube (2) and the tail part (1) of the connector body; and a fastening piece (5) is sleeved on the outer surface of the rubber tube (2), and the rubber tube (2) and the tail part (1) of the connector body are tightly connected through the fastening piece (5). The utility model has the advantages of simple operation, stable connection, effective leakage prevention, and higher tensile strength.
Description
Technical field
The utility model relates to a kind of attaching type joint that large-sized vehicle air conditioning pipeline connects that is used for, and particularly is applicable to the jointing of the air-conditioning duct connection of motorbus.
Background technology
Certain pressure need be born in the inside of air conditioning for automobiles pipeline, the pressure that is born is generally 0.8-1.2MP, but what adopt between sebific duct and the joint in the present pipeline is syndeton with three reverse hook types, the structure more complicated of this joint, therefore labor intensity of operating staff is big in the process of producing, production efficiency is low, between sebific duct and joint, there are not seal and securing member in addition, situation when connecting like this is very unstable, the temperature and pressure that bears is limited, be easy to occur the leakage situation, thereby cause the automobile air conditioner compressor cisco unity malfunction.
Summary of the invention
The utility model relates to a kind of attaching type joint that large-sized vehicle air conditioning pipeline connects that is used for, and it is not only simple to operate, and connection is stable, can prevent seepage effectively, improves tensile strength simultaneously.
The utility model has adopted following technical scheme: a kind of attaching type joint that is used for the large-sized vehicle air conditioning pipeline connection, it comprises fittings body, the sebific duct of described fittings body afterbody and air conditioning for automobiles pipeline is socket, glue pipe socket is at the fittings body afterbody, be provided with some seal grooves on the surface of fittings body afterbody, the edge of seal groove both sides is set to projection, in seal groove, be provided with seal, seal is between sebific duct and fittings body afterbody, outer surface at sebific duct is with securing member, and securing member closely is connected sebific duct with the fittings body afterbody.
Described seal groove is an arc.Described projection is higher than the surface of fittings body afterbody.Be connected for withholding between the outer surface of described securing member and sebific duct.Described seal is a sealing ring.Described sealing ring is the O RunddichtringO.Described sealing ring is the fine rubber seal of hydrogenation fourth.Described securing member is a metallic sheath.Described metallic sheath is a steel bushing.
The utlity model has following beneficial effect: the utility model is provided with sealing ring between the outer surface of the inner surface of sebific duct and fittings body afterbody, the outer surface of sebific duct is with securing member, securing member closely is connected sebific duct with fittings body, so not only simple in structure, assembling the time can reduce the workman can labour intensity, enhance productivity, and securing member can be strengthened tight connection the between sebific duct and the fittings body, owing to be provided with sealing ring and securing member, can prevent under HTHP, to produce when jointing is connected with sebific duct the seepage phenomenon so effectively, guaranteed the air conditioning for automobiles operate as normal, the sealing ring that the utility model adopts is the fine rubber seal of hydrogenation fourth, and this rubber ring has corrosion-resistant, and is high temperature resistant, wear-resisting, can improve the effect of antiseep so greatly.The edge of the utility model seal groove both sides is set to projection, and projection is higher than the surface of fittings body afterbody, so not only can increase the contact area of sebific duct inwall and jointing, and has increased tensile strength, has avoided the landing of sebific duct and fittings body.Adopt the mode of withholding to be connected between the outer surface of securing member of the present utility model and sebific duct, so not only be convenient to make, when making, only need measure the footpath of withholding at the place of withholding, and improved compactness between securing member and the sebific duct, thereby improved the compactness that is connected between sebific duct and the joint.
