Abstract

A rotary joint structure mainly comprises a base, a rotating shaft and a bearing, an adjustable base, a retainer ring, a pivoted loop which are assembled in sequence on the rotating shaft, a O-ring arranged on the adjustable base, a backstop bearing and a C-retaining ring. The front and rear edges of the adjustable base are respectively provided with the raised walls with different thickness. The raised walls are respectively in the formation of the steps of the backstop bearing and the retainer ring. The rotating shaft assembled with all components is jacketed inside the base. Thus the assembly of the rotary joint is more convenient and fast to reduce the operating costs.

Description

Rotary joint structure

Technical field

The utility model is relevant a kind of rotary joint structure, refers to that especially a kind of industries such as weaving, papermaking, rubber, plastics and chemistry etc. of being applicable to produce the swivel joint of machine tool conveyance fluids in rotation, and make the assembling of joint more convenient, joint construction fast.

Background technique

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.

Embodiment

Please consult Fig. 3 simultaneously, 4,5,6A, 6B, the utility model mainly comprises a pedestal 21, one running shaft 22, and for the C type clasp 23 that is assembled in this running shaft 22, pivoted loop 24, retaining ring 25, O type ring 26, movable base 27, C type clasp 28 and bearing 29, spacer ring 30, wherein, the front and rear edge of this movable base 27 is provided with the prominent wall 271 of different-thickness, 272, to form different heights rank portion 273,274, when assembling, earlier with bearing 29, spacer ring 30 is nested with earlier and is fixed in running shaft 22, again movable base 27 is inserted in, rank portion 273 by movable base 27 forms backstop (as Fig. 1,2 rank portion 111), make retaining ring 25, pivoted loop 24 is nested with successively is fixed in running shaft 22, and because movable base 27 is provided with a groove 275, be nested with, form sealing effect for O type ring 26;

Aforesaid running shaft 22 is after each assembly assembling, can be inserted in by pedestal 21 as shown in Figure 5, again a capping 31 is covered, to lock screw pedestal 21 and running shaft 22 are fixed by capping 31 set screws 311, so, can constitute swivel joint 2, make swivel joint 2 reach sealing as Fig. 6 A, and make its assembling more simple and direct, the test jobs when being more conducive to assemble.

See also Fig. 7 to 7K, capping 31 of the present utility model can be located at screw 311 periphery (as Fig. 7 A) or contiguous peripheral region (as Fig. 7 B), and movable base 27 also can place O type ring 26 outer rim (as Fig. 7 C) or end face (as Fig. 7 D), also or with flat pad place end face (as Fig. 7 E), this pivoted loop 24 is to be Fig. 7 F, the various combination of G, this movable base 27 then can be different compound modes with retaining ring 25, wherein, as Fig. 7 J, K is the retaining ring 25 that is inserted in different abrasion resistances with movable, and by O type ring 26 (as Fig. 7 J) or L type glue ring 251 (as Fig. 7 k) leak-stopping, or cooperate with direct heat and to be inserted in (as Fig. 7 I) and need not install glue ring leak-stopping additional, also or one-body molded with the wear-resistant components of higher quality as Fig. 7 H, no matter and, do not break away from spiritual category of the present utility model with which kind of pattern assembling.
