Abstract
A kind of novel sebific duct and steel pipe joint linkage structure, comprise steel pipe, O type circle, sleeve and sebific duct, the groove that sleeve inner bottom part is designed with, for mounting O-shaped rings, the sealing of more effective guarantee product, steel pipe joint end is designed with the form of 5 road grooves, and first groove is for fore shaft after installing sleeve, sizing material after four road grooves are below used for sebific duct extruding is filled, and also plays seal action.The utility model is applicable to the connection of automobile power steering tube road sebific duct and steel pipe, and this model utility can not only improve sealing and the working life of product, and easy processing, assembles laborsaving, improves manufacturing efficiency.
Description
Technical field
The utility model relates to the joint connecting structure of a kind of sebific duct and steel pipe, it is characterized in that adopting O type circle and groove type double sealing structure.
Background technique
At present, the linkage structure that known automobile power steering tube pipeline connector linkage structure adopts sebific duct and steel pipe to withhold, steel pipe joint end adopts pawl formula structure, insert rubber hose coupling end, rubber hose coupling end is equipped with sleeve, with special device, sleeve is withheld distortion, seals in pawl groove sebific duct being expressed to steel pipe joint end, after extruding, sebific duct wall thickness is thinning, sealing effect is bad, and working life is short, in addition, the processing of pawl structure and assembling difficulty, inefficiency.
Summary of the invention
In order to overcome sebific duct, to withhold rear wall thickness thinning, sealing effect is bad, the problem that the processing of steel pipe joint end pawl structure is difficult with assembling, the utility model provides a kind of sebific duct and steel pipe joint linkage structure, this linkage structure can not only improve the sealing of product, and processing technology is simple, assembling easily.
The utility model solves the technological scheme that its technical problem adopts: the groove being designed with mounting O-shaped rings in sleeve, sealing will than the good airproof performance not having O type circle, steel pipe joint end is designed to the form of 5 road grooves, sleeve sebific duct after withholding is extruded in groove, the wall thickness of sebific duct also than pawl structure wall thickness after, and the processing of groove type only needs just can complete with rolling ditch cutter, processing is also than being easier to, in sebific duct and steel pipe assembly process, due to the form that steel pipe end is groove, assemble more laborsaving, thus improve manufacturing efficiency.
The beneficial effects of the utility model are, sealing is more reliable, and longer service life, steel pipe joint end easy processing, sebific duct and steel pipe assemble laborsaving, enhance productivity.
Accompanying drawing explanation
Fig. 1 is a sectional arrangement drawing of the present utility model.
1. steel pipes in figure, 2.O type circle, 3. sleeve, 4. sebific duct.
Embodiment
In FIG, first O type circle (2) is installed in the groove of sleeve (3), and then sleeve (3) is set to steel pipe (1) tip side, with special device by sleeve (3) fore shaft, sleeve (3) and O type circle (2) are fixed on first grooved position of steel pipe (1), and then in cavity sebific duct (4) being inserted into sleeve (3) and steel pipe (1) until sleeve (3) bottom, sleeve (3) is withheld again with special device, sizing material after sebific duct (4) is squeezed is filled in all the other 4 grooves of steel pipe (1), plays seal action.
Claims (3)
1. sebific duct and a steel pipe joint linkage structure, its characteristic is: increase the sealing of O type circle in sleeve, rubber hose coupling end and steel pipe joint end adopt groove type to seal.
2. joint connecting structure according to claim 1, is characterized in that: sleeve inner bottom part is designed with the groove of mounting O-shaped rings.
3. joint connecting structure according to claim 1, is characterized in that: steel pipe joint end is designed with 5 road grooves.
