Abstract

The utility model relates to a novel swivel joint, which comprises a joint body, a swivel joint body, O-type sealing rings and an elastic collar. The interior of the swivel head body is sequentially provided with three annular grooves. The two O-type sealing rings and the elastic collar are respectively arranged inside the three annular grooves. The interior of the joint body is sequentially provided with a stepped hole and a groove. The swivel joint can be direct pressed into the joint body. The elastic collar is directly clamped inside the grooves of the swivel joint body and the joint body. Compared with the prior art, the 360-degree rotation of the connection part of a joint and a valve body in an automobile pipeline system can be realized and the assembly space of the entire automobile is also saved due to the adoption of the novel swivel joint. Meanwhile, the arrangement quality of the pipeline is also optimized and the manual assembly cost is lowered. he novel swivel joint has the characteristics of reasonable design, simple structure, good sealing performance, high pressure resistance, firm connection, vibration resistance, safety, reliability and the like and can be used in different environments and under different conditions.

Description

Novel swivel joint
Technical field
The invention belongs to a kind of novel pipeline coupling arrangement that can 360 ° of rotations; Comprise New Rotary pipe joint in many industries such as lathe, engineering machinery, boats and ships, mould manufacturing, household electrical appliances, medical apparatus, precision type instrument, Aero-Space; A kind of rotary pipe joint that is applied to the automobile pipe-line system especially is provided, and working medium relates to gas and liquid.
Background technique
The numerous areas of pipe connection system in industry born important effect; Automobile pipeline requisite system in the vehicle especially particularly, it has occupied crucial status in chassis braking system and steering system, and wherein the good of pipe joint is the important indicator of the whole vehicle safety of influence; What generally adopt in the present commercial car system at home all is the non-rotating pipe joint; When this pipe joint was connected with frame part, after threaded end was screwed, the nylon tube joining end can't be rotated; Cause the car load connecting pipeline disorderly and unsystematic, influence attractive in appearance; The workman very easily causes because of the space is too small and can't assemble when assembling simultaneously, thereby has strengthened the complexity of workman's assembling, has also increased the assembly space of car load, has increased cost of labor.
Summary of the invention
The object of the present invention is to provide a kind of novel pipeline coupling arrangement that can 360 ° of rotations, utilize O RunddichtringO double sealing structure, guaranteed that the gas tightness of swivel joint has reached technical requirements; Utilize circlip that joint body and swivel head body are connected; After having guaranteed that like this threaded end of swivel joint is fixing, the joint body end still can carry out 360 ° of rotations, and does not take place axially to come off; So both guaranteed sealing; Also realize 360 ° of rotations of joint, efficiently solved pipeline and connect problem disorderly and unsystematic and that the too small workman in space can't assemble, also reduced overall cost simultaneously.
Technological scheme of the present invention is: a kind of novel swivel joint comprises joint body 1, O RunddichtringO 2, circlip 3 and swivel joint body 4 compositions.It is characterized in that 11, one grooves 12 of a step hole are arranged in the said joint body 1 successively, the top, bottom has one to go up the conical surface 13; Circlip 3 is round ring bodies, and an opening slot 31 is arranged in the middle of the ring bodies; Swivel joint body 4 has first annular groove 41, second annular groove 42 and the 3rd annular groove 43 successively, and wherein the bottom outside wall of the 3rd annular groove 43 is a male cone (strobilus masculinus) 44, and outside stage casing is a hexagonal structure 45.O RunddichtringO 2 is contained in first annular groove 41 and second annular groove, 42 places of swivel joint body 4 respectively, and circlip 3 is contained in the 3rd annular groove 43 places of swivel joint body 4; Then swivel joint body 4 is contained in the step hole 11 of pipe joint body 1, wherein circlip 3 gets in the groove 12 in the joint body 1 simultaneously.The front end of said swivel joint body 4 is tapered thread or regular screw threads 46.The outside stage casing of said swivel joint body 4 is opposite side structures.
Beneficial effect:
The present invention utilizes the double seal of two O type circles to reach the sealing index that pipeline connects; Utilize the intrinsic elasticity of circlip simultaneously; The ingenious difficult problem that press-fits that has solved when assembling; Satisfy the technical requirements of swivel joint, solved existing pipe-line system and arranged rambling situation, reduced the labor intensity the when workman assembles.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further, but not as to qualification of the present invention.Provide a most preferred embodiment below:
Shown in accompanying drawing 1, a kind of rotary pipe joint comprises joint body 1, O RunddichtringO 2, circlip 3 and swivel joint body 4 compositions.It is characterized in that 11, one grooves 12 of a step hole are arranged in the said joint body 1 successively, a conical surface 13 is arranged at the top, bottom; Circlip 3 is round ring bodies, and an opening slot 31 is arranged in the middle of the ring bodies; Swivel joint body 4 has first annular groove 41, second annular groove 42, the 3rd annular groove 43 successively, and wherein the bottom outside wall of the 3rd annular groove 43 is the conical surface 44, and outside stage casing is a hexagonal structure 45.O RunddichtringO 2 is contained in first annular groove 41 and second annular groove, 42 places of swivel joint body 4 respectively, and circlip 3 is contained in the 3rd annular groove 43 places of swivel joint body 4; Then swivel joint body 4 is contained in the step hole 11 of pipe joint body 1, wherein circlip 3 gets in the groove 12 in the joint body 1 simultaneously.Said O RunddichtringO 2 is contained in first annular groove 41 and second annular groove, 42 places in the swivel joint body 4; Be close to simultaneously on the inner cylindrical surface of the step hole 11 in the joint body 1; Reach the effect of sealing, circlip 3 is mainly used in permanent joint body 1 and swivel joint body 4.When mounted, at first be pressed in the 3rd annular groove 43 of swivel joint body 4 from the bottom of swivel joint body 4 with the guiding of circlip 3 through the conical surface 44 of swivel joint bodies 4; The swivel joint body 4 that will install O RunddichtringO 2 and circlip 3 then press-fits in the step hole 11 that gets into joint body 1 together; When press-fiting; The conical surface 13 that utilizes joint body 1 is with the circlip compression, and external diameter diminishes, when circlip gets into the groove 12 of joint body 1; Circlip 3 relies on elasticity to automatically spring open, and reaches the fixedly purpose of swivel joint body 4 and joint body 1.
