[0047] Example 1: To address the problems existing in the prior art, this example provides a lightweight hydraulic cylinder, comprising a hydraulic cylinder body 1 and a mounting plate 2. The output end of the hydraulic cylinder body 1 is fixedly connected to the mounting plate 2. The piston rod on the hydraulic cylinder body 1 has a hollow structure, as shown below. Figure 2 As shown, since the piston rod at the upper end of the hydraulic cylinder body 1 has a hollow structure, the overall weight of the hydraulic cylinder body 1 is reduced, achieving lightweighting. In addition, the mounting plate 2 has reserved mounting holes, which can be used to connect with external equipment and push the connected equipment to move linearly.

[0048] Example 2: To address the problem in existing technologies where hydraulic cylinders are mostly fixed with bolts during installation, resulting in cumbersome assembly and disassembly operations, this example provides a lightweight hydraulic cylinder with a base plate 3, a positioning sleeve 4, and a clamping mechanism. The positioning sleeve 4 is fixedly connected to the middle of the upper end of the base plate 3, and the hydraulic cylinder body 1 is inserted into the middle of the positioning sleeve 4. The clamping mechanism is angled and positioned on the upper end of the base plate 3. The clamping mechanism is composed of a support plate 6, a connecting bolt 7, and a fixing clamp 8. The support plate 6 is fixedly connected to the outer side of the upper end of the base plate 3, and the upper end of the support plate 6 is threaded with a connecting bolt 7 for adjustment. The fixing clamp 8 is rotatably connected to the side of the connecting bolt 7 closest to the hydraulic cylinder body 1. The fixing clamp 8 clamps the outer side of the lower end of the hydraulic cylinder body 1. Figure 1 , Figure 3 and Figure 4 As shown, during installation, first insert the lower end of the hydraulic cylinder body 1 into the middle of the limiting plate 5, then move the cylinder body downward so that the lower end of the cylinder body is directly inserted into the positioning sleeve 4 to position the hydraulic cylinder body 1. Then, by rotating the connecting bolt 7, which is threaded to the upper end of the support plate 6, the connecting bolt 7 pushes the fixing clamp 8 to clamp and position the lower end of the cylinder body 1. The fixing clamp 8 clamps the lower end of the cylinder body at equal angles, which can very conveniently disassemble and position the hydraulic cylinder body 1.

[0049] Example 3: To address the problem of inconvenient stable installation of hydraulic cylinders of different lengths in existing technologies, this example provides a lightweight hydraulic cylinder with an adjusting mechanism 9, an auxiliary block 13, a movable frame 14, a protrusion 15, and a fixing bolt 16. A limiting plate 5 is sleeved on the outside of the hydraulic cylinder body 1, and the limiting plate 5 and the hydraulic cylinder body 1 form a sliding structure. Multiple adjusting mechanisms 9 are provided at the corner of the lower end of the limiting plate 5, and the adjusting mechanisms 9 drive the limiting plate 5 to form a lifting structure on the upper end of the base plate 3. The adjusting mechanism 9 includes a support cylinder 10, a support rod 11, and a movable sleeve 12. The movable frame 14 forms a flipping structure on the outside of the movable sleeve 12. The support cylinder 10 is fixed. A support rod 11 is telescopically connected to the middle of the support cylinder 10, and a movable sleeve 12 is fixedly connected to the lower end of the support rod 11. The movable sleeve 12 is fitted onto the outside of the support cylinder 10. The support rod 11 is fixedly connected to the lower end of the limiting plate 5. The movable sleeve 12 and the support cylinder 10 form an up-and-down sliding structure. Multiple protrusions 15 are fixedly connected to the outside of the support cylinder 10. An auxiliary block 13 is fixedly connected to the side of the movable sleeve 12. A movable frame 14 is rotatably connected to the middle of the auxiliary block 13. The movable frame 14 engages with the outside of the corresponding protrusion 15. A fixing bolt 16 is threadedly connected to the end of the movable frame 14 away from the auxiliary block 13. The fixing bolt 16 is threadedly connected to the movable sleeve 12. Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, after clamping, according to the height of the cylinder body, the limiting plate 5 is pulled upward, and the limiting plate 5 slides with the hydraulic cylinder body 1. The lower end of the limiting plate 5 is fixedly connected to the support rod 11. The limiting plate 5 drives the support rod 11 to slide with the support cylinder 10. The support rod 11 drives the movable sleeve 12 to slide on the outside of the support cylinder 10, moving the limiting plate 5 to the corresponding position on the upper end of the cylinder body. Through the setting of the limiting plate 5, the hydraulic cylinder body 1 of different sizes can be stably supported and limited, improving the stability of the installation of the hydraulic cylinder body 1. After adjustment, the movable frame 14 is directly flipped, and the movable frame 14 rotates with the auxiliary block 13. The movable frame 14 is sleeved on the outside of the protrusion 15 at the corresponding position. Then, the fixing bolt 16 is rotated to limit the movable frame 14 and the movable sleeve 12, preventing the movable frame 14 from loosening from the protrusion 15. The overall installation has good tightness.
