Description

A kind of New type rotating joint
Technical field
The utility model belongs to hardware joint technique field, more particularly, to a kind of New type rotating joint.
Background technique
Rotary joint is usually used in mechanical connection, such as giant, high pressure air rifle, since the pressure of water or gas is big, leads The mutual frictional force between rotary joint internal structure is caused to increase, prevent rotary joint limits equipment work from flexible rotating The flexibility of work;And under high pressure, the O-ring in rotary joint is easily deformed and runs out of the ring recess where it, causes to lose Go sealing performance.Therefore, it is necessary to be improved.
Summary of the invention
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of New type rotating joint.
The technical scheme adopted by the utility model is a kind of New type rotating joint, including gear shaft cap, rotation central spindle and axis Core retainer plate is provided with bearing in the gear shaft cap, and gear shaft cap is socketed in rotation central spindle by bearing, the right side of the rotation central spindle End is provided with annular groove, and O-ring and O-ring retaining ring are provided in annular groove, and the central spindle set is removably connected to gear shaft Right end and central spindle the set sealing of cap are socketed in outside O-ring and O-ring retaining ring;It is provided in the rotation central spindle and central spindle set opposite Hollow circulation duct;The right side of the O-ring retaining ring is provided with annular groove, and O-ring is matched to be mounted on annular groove On.
The right end of the gear shaft cap is provided with inner bolt hole a, and the left end of the central spindle set is provided with external screw thread a, central spindle set Left end is screwed onto the inner bolt hole a of gear shaft cap.
The left end of the rotation central spindle is provided with external screw thread b, and the right end of the central spindle set is provided with inner bolt hole b.
The rotation central spindle and central spindle, which put on to be respectively arranged with, pulls a mouthful slot.
After adopting the above structure, the utility model is compared to the prior art advantageously: the utility model uses Bearing connects gear shaft cap and rotation central spindle, and bearing has the function of anti-axial and radial force, is able to achieve rotary joint under high pressure Flexible rotating;Sealing structure uses the composite structure of O-ring and O-ring retaining ring, and O-ring is mating to be mounted on O-ring retaining ring On annular groove, O-ring is avoided by high pressure deformation and runs out of annular groove, the sound assurance sealing performance of rotary joint.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged drawing of A in Fig. 1.
Specific embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model It encloses, the present invention will be further described with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 2: a kind of New type rotating joint, including gear shaft cap 1, rotation central spindle 2 and central spindle set 3, bearing 4 is provided in the gear shaft cap 1, gear shaft cap 1 is socketed in rotation central spindle 2 by bearing 4, the rotation central spindle 2 Right end be provided with annular groove 5, be provided with O-ring 6 and O-ring retaining ring 7 in annular groove 5, the central spindle set 3 removably connects It is connected to the right end of gear shaft cap 1 and 3 sealing of central spindle set is socketed in outside O-ring 6 and O-ring retaining ring 7;The rotation central spindle 2 and central spindle Opposite hollow circulation duct 8 is provided in set 3;The right side of the O-ring retaining ring 7 is provided with annular groove 9, and O-ring 6 is matched Set is mounted on annular groove 9.
Preferably, the right end of the gear shaft cap 1 is provided with inner bolt hole a 10, and the left end of the central spindle set 3 is provided with outer spiral shell Line a 11, central spindle set 3 left end be screwed onto the inner bolt hole a 10 of gear shaft cap 1, can be realized central spindle set 3 with gear shaft cap 1 can Dismantling connection.
The left end of the rotation central spindle 2 is provided with external screw thread b 12, and the right end of the central spindle set 3 is provided with inner bolt hole b 13.Make rotary joint that can connect other supporting tools by external screw thread b 12 and inner bolt hole b 13.
It is respectively arranged in the rotation central spindle 2 and central spindle set 3 and pulls mouthful slot 14.Pull clamping of mouthful slot 14 for spanner, side Just the connection of rotary joint uses.
The utility model connects gear shaft cap 1 and rotation central spindle 2 using bearing 4, and bearing 4 has the work of anti-axial and radial force With being able to achieve the flexible rotating of rotary joint under high pressure;Sealing structure uses the composite structure of O-ring 6 and O-ring retaining ring 7, On the mating annular groove 9 for being mounted on O-ring retaining ring 7 of O-ring 6, O-ring 6 is avoided by high pressure deformation and runs out of annular groove 5, is had The sealing performance for having ensured rotary joint of power.
