the utility model provides a hydraulic system is with floating high-pressure joint, it comprises combination sealing washer, fixed joint, little O type sealing washer, gasket, jump ring for hole, floating joint and big O type sealing washer, the fixed joint is the hollow cylinder of ladder type, the surface of the little head end of fixed joint is equipped with the screw thread, the big head end of fixed joint is equipped with the connecting hole that can hold the link that the floating joint set up, the bottom of connecting hole is equipped with the sealing washer hole, be equipped with the jump ring groove on the pore wall that the connecting hole is close to port department, combination sealing washer dress is on the little head end of fixed joint, little O type sealing washer dress is in the sealing washer hole of connecting hole, the link that the connecting end of floating joint is adorned in the connecting hole that the big head end set up of fixed joint, the gasket dress is on the link that the floating joint was connected, the jump ring dress is in the jump ring inslot that the fixed joint connecting hole set up to compress tightly the link that the floating joint was connected on little O type sealing washer through the gasket, big O type sealing washer dress is in the sealing groove that the sealing washer that the floating joint sealed end set up.

Further, the gasket is a split gasket and plays a role in adjustment.

Further, the floating joint is a hollow cylinder, one end of the floating joint is a connecting end connected with the fixed joint, the other end of the floating joint is a sealing end connected with the hydraulic part, a sealing groove is arranged on the outer surface of the sealing end, and a cutting groove is arranged between the connecting end and the sealing end.

Further, the diameter of the coupling end of the floating joint is smaller than the diameter of the connecting hole of the big head end of the fixed joint, and the diameter of the cutting groove of the floating joint is smaller than the diameter of the inner hole of the gasket.

The beneficial effects of the utility model are as follows:

in order to ensure that the connecting end of the floating joint can float in the same plane, the gasket is arranged between the clamp spring for the hole and the floating joint, and is a split gasket which plays an adjusting role, so that the floating joint can float in the plane while ensuring good installation of the clamp spring. The technical problem that the existing joint cannot float in the same plane is solved. Compared with the background art, the utility model has the advantages of floating in the same plane and being applicable to a high-voltage loop.

Drawings

FIG. 1 is an exploded view of the present utility model;

FIG. 2 is a schematic diagram of the structure of the present utility model;

in the figure: the sealing device comprises a 1-combined sealing gasket, a 2-fixed joint, a 3-small O-shaped sealing ring, a 4-gasket, a 5-hole clamping spring, a 6-floating joint and a 7-large O-shaped sealing ring.

Detailed Description

The utility model is described in detail below with reference to the drawings and examples.

As shown in fig. 1-2, a floating high-pressure joint for a hydraulic system in this embodiment is composed of a combined sealing gasket 1, a fixed joint 2, a small O-shaped sealing ring 3, a gasket 4, a clamp spring 5 for a hole, a floating joint 6 and a large O-shaped sealing ring 7, wherein the fixed joint 2 is a stepped hollow cylinder, the outer surface of the small end of the fixed joint 2 is provided with threads, the large end of the fixed joint 2 is provided with a connecting hole capable of accommodating the connecting end of the floating joint, the bottom end of the connecting hole is provided with a sealing ring hole, the hole wall of the connecting hole near the port is provided with a clamp spring groove, the combined sealing gasket 1 is arranged on the small end of the fixed joint 2, the small O-shaped sealing ring 3 is arranged in the sealing ring hole of the connecting hole, the connecting end of the floating joint 6 is arranged in the connecting hole of the large end of the fixed joint 2, the gasket 4 is arranged on the connecting end of the floating joint, the clamp spring 5 for the hole is arranged in the clamp spring groove arranged in the connecting hole of the fixed joint 2, the connecting end of the floating joint 6 is pressed on the small O-shaped sealing ring 3 through the gasket 4, and the connecting end of the floating joint 6 is arranged in the sealing ring 6. The gasket 4 is a split type gasket and plays a role in adjustment. The floating joint is a hollow cylinder, one end of the floating joint is a connecting end connected with the fixed joint, the other end of the floating joint is a sealing end connected with the hydraulic part, a sealing groove is arranged on the outer surface of the sealing end, and a cutting groove is arranged between the connecting end and the sealing end.
