Abstract
The invention discloses a hydraulic rotary seal joint, which structurally comprises a K-type rubber hose joint and a K-type joint seat, wherein the K-type joint seat is internally provided with a joint cavity; the front end of the K-type rubber hose joint is provided with a spool-like joint core; the joint core is sleeved in the joint cavity and the joint core and the joint cavity are in hole-basis-system fit; the K-type joint seat and the K-type rubber hose joint are fastened by a U-shaped clamp; and both the K-type joint seat and the K-type rubber hose joint are provided with through grooves matched with the U-shaped clamp in the radial direction. Through the way, the hydraulic rotary seal joint adopts the K-type joint seat and the K-type rubber hose joint which are matched. The U-shaped clamp is used for fastening the K-type joint seat and the K-type rubber hose joint radially. The seal fastening structure can guarantee the seal pressure and prevent the split of the K-type joint seat and the K-type rubber hose joint due to overlarge hydraulic pressure.
Description
Technical field
The present invention relates to hydraulic seal member field, particularly relate to a kind of hydraulic rotating SEALING FITTING.
Background technique
Hydraulic quick connector is used for the docking of hydraulic pipe line, and its requirement has suitable bearing capacity.The kind of hydraulic quick coupling mainly is divided into welding type, joint and clinging type, flared type, fastening-pressing type and rubber hose coupling etc.Because the pressure of hydraulic pressure is quite large, the impact force that hydraulic oil pipe is popped out is very large, and ordinary couplings is done multipotency and enough born 0.5 air pressure, does not satisfy the pressure requirement in the hydraulic system far away.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of hydraulic rotating SEALING FITTING, and it is reasonable in design, and is simple in structure, is used for the docking of hydraulic system hydraulic pipe line.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts provides a kind of hydraulic rotating SEALING FITTING, described hydraulic rotating sealing configuration comprises: K type rubber hose coupling and K type connection block, be provided with the joint chamber in the K type connection block, and K type rubber hose coupling front end is the joint core of axle shape; Described joint core retainer plate is loaded in the joint chamber, and keeps unit bore system to cooperate; Tight by U-shaped kayser between K type connection block and the K type rubber hose coupling, described K type connection block upwards is equipped with the groove that cooperates U-shaped card with the footpath of K type rubber hose coupling.
Preferably, described joint core is multidiameter shaft, and the root of joint core is boss; The jointing of joint core is provided with the O RunddichtringO.
The invention has the beneficial effects as follows: a kind of hydraulic rotating SEALING FITTING is provided, uses supporting K type connection block and K type rubber hose coupling, U-shaped card is used for radially tightening K type connection block and K type rubber hose coupling.The sealing locking mechanism can guarantee its sealing load, prevents from that K type connection block and K type rubber hose coupling from producing because hydraulic pressure is excessive to collapse out phenomenon.
Description of drawings
Fig. 1 is the structural representation of a kind of hydraulic rotating SEALING FITTING of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, K type rubber hose coupling; 2, K type connection block; 3, joint core; 4, U-shaped card; 5, O RunddichtringO.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also accompanying drawing 1, the embodiment of the invention comprises:
A kind of hydraulic rotating SEALING FITTING, described hydraulic rotating sealing configuration comprises: K type rubber hose coupling 1 and K type connection block 2, be provided with the joint chamber in the K type connection block 2, K type rubber hose coupling 1 front end is the joint core 3 of axle shape; Described joint core 3 is set in the joint chamber, and keeps unit bore system to cooperate; By U-shaped card 4 lockings, described K type connection block 2 upwards is equipped with the groove that cooperates U-shaped card 4 with the footpath of K type rubber hose coupling 1 between K type connection block 2 and the K type rubber hose coupling 1.Described joint core 3 is multidiameter shaft, and the root of joint core 3 is boss; The jointing of joint core 3 is provided with O RunddichtringO 5.
The invention provides a kind of hydraulic rotating SEALING FITTING, use supporting K type connection block and K type rubber hose coupling, U-shaped card is used for radially tightening K type connection block and K type rubber hose coupling.The sealing locking mechanism can guarantee its sealing load, prevents from that K type connection block and K type rubber hose coupling from producing because hydraulic pressure is excessive to collapse out phenomenon.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
