[0033] Figure 1 It is a schematic diagram of the overall structure of a guide sleeve of a hydraulic cylinder according to an embodiment of the present disclosure.

[0034] like Figure 1-Figure 3 As shown, the guide sleeve of the hydraulic cylinder disclosed in the present invention may include: a guide sleeve assembly 1, a storage mechanism 2, a lubricating oil convenient adding mechanism 3 and other components.

[0035] Figure 2 It is a structural schematic diagram of a guide sleeve assembly 1 of a guide sleeve of a hydraulic cylinder according to an embodiment of the present disclosure.

[0036] like Figure 2 As shown, in the present disclosure, the guide sleeve assembly 1 includes a guide sleeve body 11, a connecting plate 12 and a mounting hole 13, wherein the connecting plate 12 is fixedly sleeved on the outer bottom of the guide sleeve body 11, and a plurality of mounting holes 13 are provided, and the plurality of mounting holes 13 are evenly penetrated through the top of the connecting plate 12.

[0037] Therefore, after the guide sleeve body 11 is sleeved on the outer side of the hydraulic cylinder output shaft, the connecting plate 12 can be fixed on the hydraulic cylinder by using bolts and a plurality of mounting holes 13 on the connecting plate 12 .

[0038] Figure 3 It is a schematic structural diagram of a guide sleeve storage mechanism 2 and a lubricating oil convenient adding mechanism 3 of a hydraulic cylinder according to an embodiment of the present disclosure.

[0039] like Figure 3As shown, in a preferred embodiment, the storage mechanism 2 includes a fixed seat 21, a storage groove 22 and an avoidance groove 23, wherein the fixed seat 21 is fixedly sleeved on the outside of the guide sleeve body 11, the storage groove 22 is opened on the side of the fixed seat 21, and two avoidance grooves 23 are provided, and the two avoidance grooves 23 are respectively opened at the top and bottom of the fixed seat 21 and are both connected to the storage groove 22.

[0040] Therefore, in order to utilize the storage groove 22 to store the convenient lubricating oil adding mechanism 3, and then provide protection for the convenient lubricating oil adding mechanism 3, the avoidance groove 23 is utilized to avoid the oil inlet hard pipe 36 and the oil outlet hose 37, so as to avoid obstruction when the convenient lubricating oil adding mechanism 3 is used.

[0041] like Figure 3 As shown, in the present disclosure, the lubricating oil convenient adding mechanism 3 includes a rotating block 31, a torsion spring 32, a piston cylinder 33, a piston plate 34, a piston rod 35, an oil inlet hard pipe 36, an oil outlet hose 37, a rubber ring 38 and an annular guide groove 39, wherein the rotating block 31 is rotatably arranged on the inner side of the receiving groove 22 through a pin shaft, the torsion spring 32 is fixedly connected between the inner wall of the receiving groove 22 and the rotating block 31, the piston cylinder 33 is fixedly arranged on the right side of the rotating block 31, and the piston plate 34 is slidably arranged It is placed on the inner side of the piston cylinder 33, the piston rod 35 is fixedly connected to the right side of the piston plate 34, the oil inlet hard pipe 36 is fixedly penetrated at the bottom of the piston cylinder 33, and the oil outlet hose 37 is fixedly penetrated at the top of the piston cylinder 33.

[0042] Therefore, when adding lubricating oil, the rotating block 31 is rotated by the piston rod 35, so that the rotating block 31 drives the piston cylinder 33 to move out from the inside of the storage groove 22. When the piston cylinder 33 moves, it drives the oil inlet hard pipe 36 to move out from the inside of the adjacent avoidance groove 23. At this time, the lubricating oil container is moved up, and the bottom end of the oil inlet hard pipe 36 is inserted into the lubricating oil container. Then, the piston rod 35 is pulled, so that the piston rod 35 drives the piston plate 34 to move out from the inside of the piston cylinder 33, thereby generating negative pressure, and the negative pressure sucks the lubricating oil through the oil inlet hard pipe 36. The lubricating oil is stored in the piston cylinder 33, and then the piston rod 35 is pushed. The piston rod 35 drives the piston plate 34 to push the lubricating oil inside the piston cylinder 33, so that the lubricating oil enters the inner side of the annular guide groove 39 through the oil outlet hose 37 and fills the annular guide groove 39. Subsequently, as the output shaft of the hydraulic cylinder moves, the lubricating oil inside the annular guide groove 39 is evenly attached to the surface of the output shaft of the hydraulic cylinder. After the lubricating oil is added, the piston rod 35 is released, and the torsion spring 32 drives the piston cylinder 33 to enter the storage groove 22 through the rotating block 31 and be stored.
