DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5, an adjustable joint universal head hydraulic oil cylinder, including a cylinder body 1, characterized in that a piston rod 8 is provided at the output end of the cylinder body 1, and the piston rod 8 is fixedly connected to a joint bearing seat 3 at the end on the other side away from the cylinder body 1, and a universal joint head 4 is rotatably provided on the joint bearing seat 3, and the universal joint head 4 includes a connecting flange 41, and a rotating seat 44 is provided on the connecting flange 41. The rotating seat 44 is rotatably connected to the joint bearing seat 3, and triangular ribs 42 are symmetrically fixedly connected on both sides of the rotating seat 44. The rotating seat 44 is located on the adjacent side of the triangular rib 42 and is fixedly connected to a four-corner rib 43. The rotating seat 44 can realize the rotation of the connecting flange 41. When other equipment is active, the rotation of the connecting flange 41 cooperates with the piston rod 8 to achieve self-adjustment.

[0022] A mounting chassis 2 is provided on the other side of the cylinder body 1 away from the output end. A plurality of first mounting holes 21 are evenly opened on the mounting chassis 2. The first mounting holes 21 facilitate the mounting chassis 2 to be installed on other equipment.

[0023] In addition, an oil pipe joint 7 is provided on the cylinder body 1 , and an oil pipe 6 is connected to the oil pipe joint 7 . The other end of the oil pipe 6 away from the oil pipe joint 7 is connected to the cylinder body 1 .

[0024] Furthermore, a plurality of second mounting holes 411 are evenly formed on the connecting flange 41 , and the second mounting holes 411 are used to connect the connecting flange 41 to other components.

[0025] In addition, the triangular ribs 42 and the square ribs 43 are fixedly connected to the connecting flange 41 , and the triangular ribs 42 and the square ribs 43 play a role in reinforcement.

[0026] At the same time, the joint bearing seat 3 includes a connecting plate 31, which is fixedly connected to the piston rod 8. A joint bearing 32 is provided on the other side surface of the connecting plate 31 away from the piston rod 8. A rotating shaft 33 is provided on the inner ring of the joint bearing 32. The rotating seat 44 is rotatably connected to the rotating shaft 33, and the joint bearing 32 enables the universal joint 4 to rotate.

[0027] In this embodiment, the second mounting hole 411 of the connecting flange 41 is connected to other components. When other components move, the rotating seat 44 can rotate on the rotating shaft 33, cooperate with the joint bearing 32, and when the piston rod 8 is extended or retracted, when other components move, when the piston rod 8 is extended, the rotating seat 44 moves on the rotating shaft 33, so that the connecting head that originally moved linearly can now self-adjust and rotate.

[0028] As a result, the piston rod 8 can move freely when connected to other components, thereby improving the connectivity of the hydraulic cylinder.

[0029] Furthermore, the triangular ribs 42 and the quadrangular ribs 43 can improve the strength of the universal joint 4 .

[0030] In the present invention, a joint bearing seat 3 is provided on the piston rod 8. With the cooperation of the joint bearing 32 and the rotating shaft 33, the rotating seat 44 of the universal joint 4 can be rotated. Therefore, when the piston rod 8 is telescopic and movable, the universal joint 4 can be self-adjusted when connected to other components, thereby making its connection more flexible, and the triangular ribs 42 and the square ribs 43 provided can improve the strength of the universal joint 4.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
