AI Technical Summary
Technical Problem
When the existing oil cylinders are stretched to the end, their stability decreases, resulting in a decrease in sealing.
Method used
The structural design of square plates, thin rods, long rods and guide rings is adopted. The guide ring slides on the outer edge of the long rod to increase telescopic stability, and the combination of grooves, long rods, threaded pipes and sealing nuts is achieved for convenient installation and disassembly.
Benefits of technology
Improves the expansion and contraction stability of the oil cylinder, avoids the reduction of sealing, and facilitates installation and disassembly.

Abstract
The utility model discloses an oil cylinder structure with good stability, which comprises a cylinder body, a base is arranged at one end of the cylinder body, a cylinder cover is arranged at the other end of the cylinder body, a piston rod is arranged in the cylinder body in a sliding way, a square plate is arranged on the piston rod, a circular groove for embedding the piston rod is arranged on the square plate, and four long rods are arranged between the base and the cylinder cover. The outer edge surfaces of the four long rods are sleeved with guide rings, the sides, facing the square plate, of the four guide rings are provided with slender rods, and the slender rods are arranged in a triangular mode and surround the outer edge surfaces of the long rods, the guide rings are driven by the guide rings to slide on the outer edge surfaces of the long rods, and the effect of improving the telescopic stability is achieved; the sealing nut spirally installed on the threaded pipe abuts against the long rod to complete fixation, and the effect of convenient and fast disassembly and assembly is achieved; and studs penetrate through the lug plates and the convex blocks to quickly fix the connecting blocks and the square plates, so that the effect of convenient disassembly is achieved.
