Abstract
The utility model relates to a rotary-sealing structure of a pipeline, which comprises a fixed connector, a rotary connector and a transitional connector. The fixed connector is connected with the transitional connector through threads, a groove is arranged in the middle of the rotary connector, a clamping ring is arranged in the groove, the upper end face of the clamping ring is fit with the lower end of the transitional connector, the lower end face of the clamping ring is fit with the fixed connector, at least two grooves are arranged at ends of the rotary connector, and combined sealing rings are arranged in the grooves. According to the above structure, the rotary-sealing structure of the pipeline can greatly improve connection reliability and bearable pressure of the pipeline.
Description
Technical field
The utility model relates to vehicle hydraulic or pneumatic circuit field, refers more particularly to a kind of pipeline rotary seal structure.
Background technique
Pipeline commonly used connects the general pipe joint form that adopts NBS or company standard in the automobile hydraulic system, the pipe joint structure form basically identical of the pipe joint of each company standard and NBS, after the pipe joint installation, its relative position relation all is fixed.Or the pipe joint that the part company standard arranged in installation process adjustable perfect square to, but finish be fastenedly connected after, its relative position relation all is fixed, can't satisfy the demand that hydraulic pressure or air pressure are in use adjusted the pipeline direction.
In Hydraulic Field, it is more that the rotary seal of cylinder body is studied, and the rotary seal research of pipeline is less relatively, by relevant patent is inquired about, find that majority has used the steel ball rolling bearing on the pipeline rotary seal structure, need other grease-added, the structure more complicated; Wherein in the vehicle application, notification number provides " rotary type sealed pipe joint " for the patent of CN201045431Y, it in use adjusts the demand of pipeline direction applicable to hydraulic pressure or air pressure, adopted the form of transit joint, but many two of its seal point, the possibility that leakage takes place is big, the more important thing is its transit joint, only adopt seal ring to carry out axial restraint between swivel joint and the permanent joint, when using air pressure (or hydraulic pressure) when pressure is excessive, or when misoperation (tearing pipeline because of carelessness) takes place, swivel joint is very easy cuts off seal ring, swivel joint can directly be deviate from from permanent joint and security incident takes place, transit joint and permanent joint only depend on the locking of transit joint end face, loosening phenomenon also easily takes place, so " rotary type sealed pipe joint " patent only is applicable to the gas-liquid of low pressure and transmits, and need be arranged in the place that is difficult for producing misoperation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of effective high voltage bearing pipeline rotary seal structure.
The utility model provides a kind of pipeline rotary seal structure, comprises permanent joint, swivel joint, transit joint, and described permanent joint and transit joint are by being threaded; The intermediate portion is provided with a groove on the described swivel joint, places snap ring in the groove, fits in the upper-end surface of snap ring and the lower end of described transit joint, and the lower end surface of snap ring and the platform of described permanent joint are fitted; The end of described swivel joint offers at least two grooves, is provided with combined seal ring in the groove.
In the such scheme, described permanent joint is that ladder is poroid, and big one section in aperture is processed into internal thread; Described transit joint is the hollow bolt sample, and the upper end head is provided with threaded hole of steel, and outside thread and the pairing of permanent joint internal thread are processed in the bottom.
Preferably, described snap ring is a metal clasp, is combined by two and half snap rings, and one of them half snap ring is connected with another half snap ring by steel wire.
In the such scheme, described transit joint upper end head is six sides or tetragonal.
More preferred, described groove is a circular groove.
In the such scheme, the threaded hole of steel of described transit joint upper end head is at least two.
The utility model has been owing to adopted said structure, can greatly improve the pressure that pipeline bears and the reliability of connection.
Description of drawings
The structural representation of the pipeline rotary seal structure that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the partial enlarged drawing of I part among Fig. 1;
Fig. 3 is the partial enlarged drawing of II part among Fig. 1;
Fig. 4 is the plan view of half snap ring;
Fig. 5 is the side view of half snap ring.
Embodiment
Shown in Fig. 1,2,3,4,5, permanent joint 1 is made shoulder hole, and big one section in aperture is processed into internal thread; Transit joint 3 is the hollow bolt sample, and the upper end head adopts six sides or tetragonal, and the processing threaded hole of steel, and outside thread and the pairing of permanent joint 1 internal thread are processed in the bottom, and transit joint 3 skies are enclosed within on the swivel joint 2; Swivel joint 2 is two or more at the circular groove that combined seal ring 7 is set foremost, and combined seal ring 7 is placed in the circular groove, with high pressure oil or gas and extraneous the partition, guarantees sealability.Swivel joint 2 intermediate portions are provided with the circular groove of snap ring 5, and snap ring 5 is placed in the circular groove, are combined by two and half snap rings, and one of them half snap ring is connected with another half snap ring by steel wire 6.Snap ring 5 can be a metal clasp.
During installation, transit joint 3 skies are enclosed within on the swivel joint 2, snap ring 5 usefulness steel wires 6 are fixed in the circular groove of swivel joint 2, again combined seal ring 7 is placed in the circular groove of swivel joint 2, a swivel joint 2 and transit joint 3 parts are put into permanent joint 1, screw transit joint 3, guarantee that transit joint 3 is pressed on snap ring 5 on the shoulder of permanent joint 1, at last steel wire 4 is penetrated in the threaded hole of steel of transit joint 3, with steel wire 4 transit joint 3 and permanent joint 1 are banded together, prevent that transit joint 3 is loosening.After the installation, this structure can transmit pressurized gas or liquid, and swivel joint 2 can rotate freely, and is a whole set of simple in structure, and the reliability height is applicable to that multiple different pipeline connects operating mode.
Should be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
