Sep 2, 2026 — Jiangsu Hengli Hydraulic Co., Ltd. has been officially granted a utility‑model patent titled “Hydraulic Cylinder Connection Structure with Quick Disassembly” (Patent No. CN224706055U).

In field‑service scenarios for construction machinery, mining and agricultural equipment, cylinder replacement is a frequent maintenance task. Conventional bolt‑heavy flange/pin‑eye connections are time‑consuming to disassemble, and rusted bolts often cause extra downtime.

This new patent adopts a rotating lock‑in design with clamping blocks and annular grooves for both cylinder fixed end and rod end. The cylinder can be locked by rotating the clamping block into the groove, and unlocked by reverse rotation. It reduces bolt‑handling work while maintaining mechanical impact resistance.

The innovation simplifies on‑site disassembly‑assembly, lowers maintenance difficulty and cuts equipment downtime. Applicable to construction, mining and agricultural cylinders, it represents Hengli’s continuous R&D focus on product serviceability for OEM and after‑market customers.
