[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hydraulic cylinder that is easy to assemble;

[0024] Example 1:

[0025] To facilitate the assembly of the flange and the hydraulic cylinder body 1, making the connection and separation of the flange and the hydraulic cylinder body 1 simple and quick, a locking mechanism is engaged on the upper surface of the screw-locking mechanism. The locking mechanism includes: a cylinder head 5, with a first through hole 11 and a limiting groove 18 on its inner surface; a connector 6 on the upper surface of the cylinder head 5, with a slot 12 and a second through hole 13 on its upper surface; a connecting rod 16 engaged with the inner surfaces of the first through hole 11 and the second through hole 13; a limiting rod 17 fixedly installed on the side wall of the connecting rod 16; a spring 14 fixedly installed on the bottom surface of the first through hole 11; and a movable plate 15 fixedly connected to the top of the spring 14. The second flange 4 and the hydraulic cylinder body 1 are limited by the limiting rod 17 and the limiting groove 18. The bottom end of the connecting rod 16 contacts the movable plate 15. The inner diameter of the first through hole 11 and the second through hole 13 is larger than the outer diameter of the connecting rod 16, thus achieving locking. The mechanism consists of two sets, symmetrically arranged around the hydraulic cylinder body 1. By aligning the limiting rod 17 on the connecting rod 16 with the slot 12 and inserting it into the second through hole 13 and the first through hole 11, the connecting rod 16 is rotated downwards during insertion due to the compression of the spring 14 and the movable plate 15. When the limiting rod 17 is fully inserted into the limiting groove 18, the flange is connected to the hydraulic cylinder body 1 by the rebound of the spring 14 and the movable plate 15. When disassembling the flange from the hydraulic cylinder body 1, rotating the connecting rod 16 causes the limiting rod 17 to rotate to the slot 12. The rebound of the spring 14 and the movable plate 15 then separates the flange from the hydraulic cylinder body 1. This makes the connection and separation of the flange from the hydraulic cylinder body 1 simple and quick, reducing disassembly and assembly time and labor costs. It also facilitates disassembly and maintenance when the inside of the hydraulic cylinder needs cleaning, significantly shortening maintenance time and reducing losses caused by equipment downtime.

[0026] Working Principle: To facilitate the assembly of the flange and hydraulic cylinder body 1, and to simplify and extricate them from each other, the limiting rod 17 on the connecting rod 16 is aligned with the slot 12 and inserted into the second through hole 13 and the first through hole 11. Compression of the spring 14 and the movable plate 15 causes the connecting rod 16 to rotate during insertion. When the limiting rod 17 is fully inserted into the limiting slot 18, the spring 14 and the movable plate 15 rebound, connecting the flange and the hydraulic cylinder body 1. To disassemble the flange and hydraulic cylinder body 1, rotating the connecting rod 16 rotates the limiting rod 17 to the slot 12. The spring 14 and the movable plate 15 then separate the flange from the hydraulic cylinder body 1. This simplifies and extricates the flange and hydraulic cylinder body 1, reducing assembly and disassembly time and labor costs. It also facilitates disassembly and maintenance when cleaning the inside of the hydraulic cylinder, significantly shortening maintenance time and reducing losses due to equipment downtime.
