Because known swivel joint is for reaching the ongoing sealing fully of rotation, therefore structure is very complicated, cause maintenance, the assembling difficulty, and known rotary joint spoilage height, poor air-tightness, the leakage of liquid (gas) body of joint causes flowing through, as Fig. 1, shown in 2, this is novel to be to comprise a pedestal 11, single-revolution ring 12, one retaining ring 13, one C type ring 14, one C type clasp 15, two bearings 16, one running shaft 17 and another C type clasp 18, wherein, this pedestal 11 is to be provided with rank portion 111 in the inner edge middle position, during assembling, be earlier bearing 16 to be placed on running shaft 17, running shaft 17 is inserted in by the opening 112 of pedestal 11 after, in another opening 113 retaining ring 13 assemblies such as grade are assembled on the running shaft 17 successively, and form backstop by rank portion 111, again a base 19 fits are fixed at last.
Though aforesaid structure can be improved known swivel joint poor air-tightness, disappearance that spoilage is high, but need in pedestal 11 two ends operations during owing to assembling, in the test, fit on also can't be more quick, simple and direct, the claimant satisfies germinating improvement again, pray and make the assembling of rotary joint more convenient, to reduce operating cost.
Summary of the invention
Main purpose of the present utility model is promptly providing a kind of rotary joint structure, makes the assembling of swivel joint more simple and easy, quick.
The purpose of this utility model is achieved in that a kind of rotary joint structure, mainly is to be provided with a pedestal, a running shaft, and the assembly such as bearing, movable base, retaining ring, pivoted loop and O type ring, C type clasp that is assembled in this running shaft,
This movable base is the prominent wall that is respectively equipped with different-thickness according to the demand of the component design of arranging in pairs or groups in front and rear edge, to form different rank portions, backstop by the rank portion of this movable base makes each assembly be assembled in running shaft earlier and is inserted in the pedestal again, makes the assembling of swivel joint more simple and easy, quick.
This movable base is provided with groove in its leading edge or apical margin, for being nested with O type ring, to constitute sealing effect.
This movable base can be nested with the retaining ring of wear-resistant material according to the demand of design, and constitutes leak-stopping by O type ring or L type glue ring.
This movable base can be inserted in retaining ring according to the demand of design with the direct heat cooperation, to exempt installing O type ring.
This movable base can be one-body molded by high-abrasive material.
The utility model makes the assembling of swivel joint more simple and direct, quick to be provided with sealable movable base, reduces the cost of operation, is the design of a practicality.
