Abstract
A kind of universal hydraulic joint, comprises pipe joint, and described pipe joint one end is connected with nut sleeve; One bulb joint comprises ball head, and ball head overcoat has the nut sleeve matching with it; Between described ball head and pipe joint, be provided with seal ring, seal ring is positioned at nut sleeve.Universal hydraulic joint of the present utility model has been transformed into the one end being connected with oil pipe on script pipe joint the front end of bulb joint, due to the ball shape of the ball head of bulb joint, in the time that the front end of bulb joint need change position, only need by rotating sphere head, even if there is some obstacle in the position that therefore hydraulic joint is arranged on oil cylinder, also can pass through rotating sphere head, adjust the convenient position being connected with oil pipe of bulb joint front end, hydraulic joint can not occur and be difficult to the situation that connecting fluid crimp head even cannot connect.
Description
Technical field
The utility model relates to a kind of universal hydraulic joint.
Background technique
The utilization of hydraulic joint is very extensive, but main function is no more than for being connected between oil cylinder and oil pipe, after but once general hydraulic joint is installed on oil cylinder, the port that hydraulic joint is connected with oil pipe just cannot move, therefore in the time that hydraulic joint is arranged on position on oil cylinder and has some obstacle, easily there is oil pipe and be difficult to the situation that connecting fluid crimp head even cannot connect, cause the trouble in work.
Summary of the invention
The utility model will solve the technical problem that oil pipe is difficult to the situation that connecting fluid crimp head even cannot connect easily occurs in the time that the position that hydraulic joint is arranged on oil cylinder exists some obstacle.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of universal hydraulic joint, comprises pipe joint, it is characterized in that: described pipe joint one end is connected with nut sleeve; One bulb joint comprises ball head, and ball head overcoat has the nut sleeve matching with it; Between described ball head and pipe joint, be provided with seal ring, seal ring is positioned at nut sleeve.
Described seal ring cross section is spill, and the afterbody sphere of the inner concave shape face of seal ring and the ball head of bulb joint matches.
The beneficial effects of the utility model are:
Compared with prior art, the universal hydraulic joint that adopts the utility model structure has solved by the existence of bulb joint the problem that one end that pipe joint is connected with oil pipe cannot be moved, the one end being connected with oil pipe on script pipe joint is transformed into the front end of bulb joint, due to the ball shape of the ball head of bulb joint, in the time that the front end of bulb joint need change position, only need by rotating sphere head, even if there is some obstacle in the position that therefore hydraulic joint is arranged on oil cylinder, also can pass through rotating sphere head, adjust the convenient position being connected with oil pipe of bulb joint front end, can there is not hydraulic joint and be difficult to the situation that connecting fluid crimp head even cannot connect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model universal hydraulic joint.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Refer to Fig. 1, the utility model provides a kind of universal hydraulic joint, comprises pipe joint (1), and described pipe joint (1) one end is connected with nut sleeve (2); One bulb joint (3) comprises ball head (4), and ball head (4) overcoat has the nut sleeve (2) matching with it; Between described ball head (4) and pipe joint (1), be provided with seal ring (5), seal ring (5) is positioned at nut sleeve (2).
The utility model has been transformed into by nut sleeve (2) one end that pipe joint (1) is above connected with oil pipe originally the front end of bulb joint (3), due to the ball shape of the ball head (4) of bulb joint, in the time that the front end of bulb joint (3) need change position, only need the ball head (4) matching by rotation and nut sleeve (2) inwall, even if there is some obstacle in the position that therefore hydraulic joint is arranged on oil cylinder, also can pass through rotating sphere head (4), adjust the convenient position being connected with oil pipe of bulb joint (3) front end, can there is not hydraulic joint and be difficult to the situation that connecting fluid crimp head even cannot connect.
Described seal ring (5) cross section is spill, the afterbody sphere of the ball head (4) of the inner concave shape face of seal ring (5) and bulb joint matches, extremely agreeing with of the inner concave shape face of seal ring (5) and ball head (4) afterbody sphere, make better tightness between the two, and be rigid seal between ball head (4) and nut sleeve (2) inwall, seal by seal ring (5), these two kinds of modes of rigid seal seal, ensure the sealing effect of universal hydraulic joint, without the problem of worrying to cause because of rotating sphere head (4) hydraulic joint sealing variation.
Claims (2)
1. a universal hydraulic joint, comprises pipe joint, it is characterized in that: described pipe joint one end is connected with nut sleeve; One bulb joint comprises ball head, and ball head overcoat has the nut sleeve matching with it; Between described ball head and pipe joint, be provided with seal ring, seal ring is positioned at nut sleeve.
2. a kind of universal hydraulic joint according to claim 1, is characterized in that: described seal ring cross section is spill, the afterbody sphere of the inner concave shape face of seal ring and the ball head of bulb joint matches.
