[0002] A hydraulic cylinder is a retractable electro-hydraulic power structure that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It is simple in structure and reliable in operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] Chinese Patent CN221647316U discloses a high-frequency hydraulic cylinder, including a high-frequency hydraulic cylinder body, a cylinder rear cover, and a first bolt. A cylinder front cover is installed on the right outer wall of the high-frequency hydraulic cylinder body, and a fixing mechanism is installed on the outer wall of the cylinder front cover. A connecting mechanism is installed inside the high-frequency hydraulic cylinder body. This utility model relates to the field of hydraulic cylinder technology. The piston rod can be passed through the first connecting plate and the first sealing ring inside the cylinder front cover in sequence, and then the piston rod can be passed through the guide sleeve and the support ring. The cylinder front cover is then installed on the high-frequency hydraulic cylinder body. Then, the screw is inserted into the through holes of the first and second connecting plates, and the stop block cooperates with the third connecting plate to block the screw. Then, the washer and nut are installed on the screw, and the cylinder front cover is fixed to the high-frequency hydraulic cylinder body.

[0018] Example 1

[0019] like Figures 1 to 4As shown, this utility model proposes a retractable electro-hydraulic power structure, including a hydraulic cylinder body 1, a front cylinder cover body 3, and a rear cylinder cover body 4. A piston rod is mounted on the front cylinder cover body 3. The specific structure and principle are detailed in the patent with authorization announcement number CN221647316U, and will not be repeated here. Annular seats 2 are installed at both ends of the outer circumference of the hydraulic cylinder body 1. The front cylinder cover body 3 is inserted into the outside of one end of the hydraulic cylinder body 1, fitting snugly against the outer circumference of the hydraulic cylinder body 1 and abutting against the corresponding annular seat 2. The rear cylinder cover body 4 is inserted into... The cylinder rear cover body 4 is attached to the outer surface of the hydraulic cylinder body 1 and abuts against the corresponding annular seat 2. A quick-release mechanism is provided between the annular seat 2 and the cylinder front cover body 3 or between the annular seat 2 and the cylinder rear cover body 4. The quick-release mechanism is used to quickly detach and install the cylinder rear cover body 4 and the hydraulic cylinder body 1 or the cylinder front cover body 3 and the hydraulic cylinder 1. The quick-release mechanism consists of multiple sets of limiting components set on the annular seat 2 and multiple sets of insert rods 301 installed on the cylinder front cover body 3 or the cylinder rear cover body 4. The insert rods 301 are detachably connected to the limiting components.

[0020] Furthermore, an annular sealing end is embedded on the annular seat 2 and at the end that abuts against the cylinder front cover body 3 or cylinder rear cover body 4, thereby improving the sealing performance at the connection between the annular seat 2 and the cylinder front cover body 3 or cylinder rear cover body 4 and preventing leakage at the connection end of the hydraulic cylinder body 1.

[0021] Furthermore, the limiting assembly includes an extension seat 201, an L-shaped seat 208, a spring 204, and a second insertion hole 206; the extension seat 201 is mounted on an annular seat 2, and the annular seat 2 has a first insertion hole 202; the L-shaped seat 208 is mounted on the extension seat 201, and an adjusting rod 203 slides through the L-shaped seat 208 at one end away from the extension seat 201, the adjusting rod 203 is slidably connected to the extension seat 201, and a clearance groove communicating with the bottom of the first insertion hole 202 is provided inside the annular seat 2, the adjusting rod 203 is slidably connected to the clearance groove; the spring 204 is sleeved on the outside of the adjusting rod 203, one end of the spring 204 is connected to the adjusting rod 203, and the other end is connected to the L-shaped seat 208; the second insertion hole 206 is provided on the adjusting rod 203, and an insertion block 207 is installed inside the second insertion hole 206.

[0022] Furthermore, the insertion rod 301 is slidably inserted into the first insertion hole 202 and the second insertion hole 206, and the insertion block 207 is slidably inserted into the third insertion hole 302.

[0023] In this embodiment, the adjusting rod 203 is pressed and slid towards the relief groove inside the annular seat 2 until the adjusting rod 203 abuts against the bottom end of the relief groove. Then, the insert block 207 on the second insertion hole 206 is pushed towards the relief groove. Then, the cylinder rear cover body 4 is slid into the annular seat 2 along the outer circumferential surface of one end of the hydraulic cylinder body 1 until the cylinder rear cover body 4 abuts against the annular seat 2. At this time, the insert rod 301 on the cylinder rear cover body 4 slides into the first insertion hole 202. The pressing on the adjusting rod 203 is released. Under the restoring force of the compressed spring 204, the adjusting rod 203 is driven to slide along the L-shaped seat 208 towards the initial position until... Insert the insert block 207 on the second insertion hole 206 into the third insertion hole 302 on the insert rod 301. At this time, the second insertion hole 206 and the insert block 207 limit the insert rod 301 on the extension seat 201, thereby quickly installing the cylinder rear cover body 4 on the hydraulic cylinder body 1. In the same way, the cylinder front cover body 3 is installed on the other end of the hydraulic cylinder body 1 through the limiting component. When it is necessary to remove the cylinder front cover body 3 and the cylinder rear cover body 4, press the adjusting rod 203 against the annular seat 2 again to separate the insert rod 301 on the cylinder front cover body 3 or the cylinder rear cover body 4 from the limiting component and complete the removal, which is convenient for the staff to inspect and repair.

[0024] Example 2

[0025] like Figures 1 to 4 As shown, the retractable electro-hydraulic power structure proposed in this utility model, compared with Embodiment 1, includes a first locking seat 303 and a second locking seat 401 in the quick-release mechanism. The insertion rod 301 is threadedly connected to the outer peripheral surface of the cylinder front cover body 3, and the second locking seat 401 is threadedly connected to the outer peripheral surface of the cylinder rear cover body 4. A limit port 205 is provided on the adjusting rod 203, and the second locking seat 401 or the first locking seat 303 abuts against the side wall of the corresponding limit port 205.

[0026] Furthermore, the extension seat 201 and the end face away from the annular seat 2 are provided with a threaded portion B that is consistent with the threaded portion A on the outer peripheral surface of the cylinder front cover body 3 or the cylinder rear cover body 4. The limiting port 205 and the end near the second insertion hole 206 are provided with a threaded portion C that is consistent with the threaded portion A. The second locking seat 401 or the first locking seat 303 is threadedly connected to the corresponding threaded portion A, threaded portion B and threaded portion C.

[0027] In this embodiment, after the insertion rod 301 is connected to the extension seat 201, the first locking seat 303 is rotated to move along the outer circumferential surface of the cylinder front cover body 3, and then connected to the threaded portion B on the top surface of the extension seat 201. Next, it is connected to the threaded portion C on the limiting port 205 until the side wall of the first locking seat 303 abuts against the side wall of the limiting port 205. Then, the adjusting rod 203 is fixed on the L-shaped seat 208 by the first locking seat 303 and the limiting port 205, which prevents the adjusting rod 203 from being easily pressed under external force and improves the stability of the adjusting rod 203. The second locking seat 401 is connected to the threaded portion C on the corresponding limiting port 205 in this way. When it is necessary to remove the cylinder rear cover body 4 or the cylinder front cover body 3, it is only necessary to rotate and adjust the corresponding second locking seat 401 and the first locking seat 303 so that the adjusting rod 203 is no longer restricted, and the corresponding limiting component can be adjusted.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
