[0002] An inverted cylinder generally refers to a hydraulic system in which the cylinder's mounting orientation is altered, adjusting the cylinder's operating mode and force direction. This installation method is often used in applications requiring space savings, specific motion paths, or working environments, and is often associated with the specific use case of the hydraulic cylinder.

[0003] Existing inverted cylinders have sealing issues. When the cylinder is installed upside down, the seals may wear unevenly due to changes in gravity, resulting in poor sealing. Furthermore, after the cylinder is inverted, it is necessary to confirm that the cylinder design can withstand loads from different directions to avoid structural damage. Utility Model Content

The piston drives the piston rod to move, and the rod head is fixedly installed on the other end of the piston rod.

[0007] In a further embodiment, a screw hole is formed at the other end of the cylinder body, a screw plug is screwed onto the screw hole, and a washer is provided between the screw plug and the cylinder body.

[0008] In a further embodiment, the piston and the rod head are in the shape of bosses, the piston rod is in the shape of a hollow cylinder, and the boss portions of the piston and the rod head are sleeved in the piston rod.
