Description

A bidirectional booster hydraulic cylinder Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, specifically a bidirectional booster hydraulic cylinder. Background Technology

[0002] Hydraulic cylinders are actuators in hydraulic systems. Their core function is to convert hydraulic energy (the pressure energy of hydraulic oil) into mechanical energy to achieve linear reciprocating motion or oscillation, thereby driving mechanical parts to complete various actions (such as pushing, pulling, lifting, clamping, etc.). They are widely used in engineering machinery, industrial equipment, agricultural machinery, automobiles, aerospace and other fields, and are an indispensable power transmission component in modern machinery. A bidirectional booster hydraulic cylinder is a hydraulic actuator that can achieve boosting function in both directions of piston movement. Through a special structural design, it enables the hydraulic oil to increase the system pressure during the extension and retraction of the piston, thereby meeting the requirements of some working conditions that require bidirectional high-pressure output.

[0003] Chinese Utility Model Patent Publication No. CN214171003U discloses a bidirectional hydraulic cylinder. This cylinder is designed for easy lifting and movement via a handle and anti-slip sleeve, increasing ease of use. The anti-slip sleeve's textured surface provides a non-slip surface, enhancing safety and stability during lifting. The piston rod's output direction is adjusted, and a bolt is used to install and fix a diagonal support bracket through a through-hole. However, this bidirectional hydraulic cylinder lacks a proper mounting structure for the cylinder body, making quick disassembly and assembly difficult. Furthermore, the absence of a sealing structure leads to easy oil leakage within the cylinder, resulting in low sealing performance and poor practicality, hindering its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bidirectional booster hydraulic cylinder, which can effectively solve the problems of existing hydraulic cylinders that do not have an installation structure for the cylinder body, making it inconvenient to quickly disassemble and assemble during use or assembly, and lack a sealing structure, resulting in easy oil leakage in the cylinder barrel, low sealing performance, poor practicality, and difficulty in widespread use.

[0005] The technical solution adopted by this utility model is as follows: a bidirectional booster hydraulic cylinder, including a base and a hydraulic cylinder body disposed at the top of the base. A positioning block is fixedly installed on the side of the hydraulic cylinder body near the base. A through groove is formed on the outer wall of the positioning block. A slot is formed on the outer wall of the hydraulic cylinder body. A fixing member is fixedly installed on the side of the base near the hydraulic cylinder body. An insert is fixedly installed on the side of the fixing member near the hydraulic cylinder body. A positioning groove, a movable groove, a guide groove, and a limiting groove are formed on the inner edge of the base. A limiting block is disposed on the inner wall of the movable groove. A guide block and a pull rod are fixedly installed on the outer wall of the limiting block.

[0006] Preferably, the positioning block and the positioning slot are connected by a plug-in joint, and the plug and the slot are connected by a plug-in joint.

[0007] Using the above technical solution, the operator inserts the positioning block into the positioning slot and the insert block into the slot, which enables rapid positioning of the hydraulic cylinder body. Without complicated calibration work, the hydraulic cylinder body and the base can be quickly aligned, improving installation efficiency and saving labor costs.

[0008] Preferably, the movable groove, the through groove, and the limiting groove are connected, and the limiting block extends through the through groove into the interior of the limiting groove.

[0009] With the above technical solution, after the hydraulic cylinder body is quickly positioned, the operator pulls the limiting block with a pull rod, so that the limiting block extends through the through groove into the interior of the limiting groove, which can realize the rapid limiting of the hydraulic cylinder body. It is convenient to quickly disassemble and assemble during use or assembly, and has high practicality.

[0010] Preferably, the guide block and the guide groove are slidably connected, and the cross-section of the guide block is evenly distributed.

[0011] Through the above technical solution, by cooperating with the guide block and the guide groove, the guide block slides inside the guide groove during the movement of the limiting block, thereby playing a guiding role and improving the overall stability.

[0012] Preferably, the hydraulic cylinder body includes a cylinder barrel, end cap one, end cap two, through hole one, through hole two, positioning block two, positioning groove two, screw, nut, fixing block, mounting groove and sealing ring. End cap one and end cap two are provided at both ends of the cylinder barrel. Through hole one is opened on the outer wall of end cap one, and through hole two is opened on the outer wall of end cap two. Positioning block two is fixedly installed at both ends of the cylinder barrel. Positioning groove two is opened on the side of end cap one and end cap two near the cylinder barrel. Screw adapted to through hole one and through hole two is inserted into the outer wall of end cap one. Nut is threadedly connected to the outer edge of the screw. Fixing block is fixedly installed on the side of end cap one and end cap two near the cylinder barrel. Mounting groove is opened on the outer wall of fixing block. Sealing ring is provided on the inner edge of mounting groove. Positioning block two is inserted into positioning groove two. The cross-section of positioning block two is "L" shaped.

[0013] Using the above technical solution, the staff inserts the second positioning block into the second positioning slot, and then rotates the first and second end caps to achieve rapid positioning of the first and second end caps.

[0014] Preferably, the screw passes through through hole one and through hole two, and the nut abuts against end cap two.

[0015] With the above technical solution, after the end cap one and end cap two are quickly positioned, the workers insert the screw through the through hole one and through hole two, and then connect the nut to the screw thread, so that the nut abuts against end cap two, which can realize the quick positioning of end cap one and end cap two with the cylinder. After long-term use, it is easy to repair or replace them, and it has high practicality.

[0016] Preferably, the sealing ring is a rubber ring, and three interconnected sealing rings are provided, with the three sealing rings distributed at equal intervals.

[0017] Through the above technical solution, because the rubber ring has good sealing performance, the design of the sealing ring can prevent the oil inside the cylinder from leaking out through the connection between end cap one and end cap two and the cylinder, thus improving the overall sealing performance. The design of three sealing rings further improves the overall sealing performance.

[0029] 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.

[0030] Example 1:

[0031] As shown in Figures 1-6, the present invention provides a bidirectional boosting hydraulic cylinder, including a base 1 and a hydraulic cylinder body 2 disposed at the top of the base 1. A positioning block 3 is fixedly installed on the side of the hydraulic cylinder body 2 near the base 1. A through groove 4 is opened on the outer wall of the positioning block 3. A slot 5 is opened on the outer wall of the hydraulic cylinder body 2. A fixing member 6 is fixedly installed on the side of the base 1 near the hydraulic cylinder body 2. An insert block 7 is fixedly installed on the side of the fixing member 6 near the hydraulic cylinder body 2. A positioning groove 9, a movable groove 10, a guide groove 11 and a limiting groove 12 are opened on the inner edge of the base 1. A limiting block 13 is provided on the inner wall of the movable groove 10. A guide block 14 and a pull rod 15 are fixedly installed on the outer wall of the limiting block 13.

[0032] Specifically, the hydraulic cylinder body 2 includes a cylinder barrel 201, end cap 1 202, end cap 203, through hole 1 204, through hole 205, positioning block 206, positioning groove 207, screw 208, nut 209, fixing block 210, mounting groove 211, and sealing ring 212. End cap 1 202 and end cap 203 are provided at both ends of the cylinder barrel 201. Through hole 1 204 is provided on the outer wall of end cap 1 202, and through hole 205 is provided on the outer wall of end cap 203. Positioning block 206 is fixedly installed at both ends of the cylinder barrel 201. 3. Positioning grooves 207 are provided on the side of the end cap 202 closest to the cylinder 201. A screw 208, compatible with through holes 204 and 205, is inserted into the outer wall of the end cap 202. A nut 209 is threaded onto the outer edge of the screw 208. A fixing block 210 is fixedly installed on the side of the end caps 202 and 203 closest to the cylinder 201. An installation groove 211 is provided on the outer wall of the fixing block 210, and a sealing ring 212 is provided on the inner edge of the installation groove 211. Positioning block 206 is inserted into the positioning grooves 207, and its cross-section is L-shaped. The advantage is that by inserting positioning block 206 into the positioning grooves 207 and then rotating the end caps 202 and 203, quick positioning of the end caps 202 and 203 can be achieved.

[0033] Specifically, the screw 208 passes through through hole 204 and through hole 205, and the nut 209 abuts against end cap 203. The advantage is that after quickly positioning end caps 202 and 203, the operator can pass the screw 208 through through hole 204 and through hole 205, and then thread the nut 209 onto the screw 208, causing the nut 209 to abut against end cap 203. This allows for quick positioning of end caps 202 and 203 relative to the cylinder 201. After prolonged use, this facilitates maintenance or replacement, making it highly practical.

[0034] Specifically, the sealing ring 212 is a rubber ring, and three interconnected sealing rings 212 are arranged at equal intervals. The advantage is that, due to the good sealing performance of the rubber ring, the design of the sealing ring 212 prevents oil inside the cylinder 201 from leaking out through the connection between end cap 1 202 and end cap 203 and the cylinder 201, thus improving the overall sealing performance. The design of three sealing rings 212 further enhances the overall sealing performance.

[0035] Example 2:

[0036] As shown in Figures 2-6, as an improvement on the previous embodiment, to further facilitate the installation of the hydraulic cylinder body 2, specifically, the positioning block 3 and the positioning groove 9 are installed by insertion, and the insert block 7 and the slot 5 are installed by insertion. The advantage is that by inserting the positioning block 3 into the positioning groove 9 and simultaneously inserting the insert block 7 into the slot 5, the hydraulic cylinder body 2 can be quickly positioned without complex calibration work, thus achieving rapid alignment between the hydraulic cylinder body 2 and the base 1, improving installation efficiency, and saving labor costs.

[0037] Specifically, the movable groove 10, the through groove 4, and the limiting groove 12 are interconnected, and the limiting block 13 extends through the through groove 4 into the interior of the limiting groove 12. The advantage is that after the hydraulic cylinder body 2 is quickly positioned, the operator can pull the limiting block 13 using the pull rod 15, causing the limiting block 13 to extend through the through groove 4 into the interior of the limiting groove 12. This allows for rapid positioning of the hydraulic cylinder body 2, facilitating quick disassembly and assembly during use or assembly, and making it highly practical.

[0038] Specifically, the guide block 14 and the guide groove 11 are slidably connected, and the cross-section of the guide block 14 is evenly distributed. The advantage is that, through the cooperation between the guide block 14 and the guide groove 11, the guide block 14 slides inside the guide groove 11 during the movement of the limiting block 13, playing a guiding role and improving the overall stability.

[0039] Working Principle: During installation, the operator inserts positioning block 206 into positioning groove 207, and then rotates end cap 202 and end cap 203 to achieve rapid positioning of end cap 202 and end cap 203. After quickly positioning end cap 202 and end cap 203, the operator inserts screw 208 through through hole 204 and through hole 205, and then threads nut 209 onto screw 208, causing nut 209 to abut against end cap 203. This allows for rapid positioning of end cap 202 and end cap 203 relative to cylinder 201. After prolonged use, this facilitates maintenance or replacement, making it highly practical. After assembling the hydraulic cylinder body 2, the operator inserts positioning block 3 into positioning groove 9 and inserts block 7 into slot 5, achieving rapid positioning of the hydraulic cylinder body 2 without complex calibration work. The quick alignment of the cylinder body 2 and the base 1 improves installation efficiency and saves labor costs. After the hydraulic cylinder body 2 is quickly positioned, the operator pulls the limiting block 13 through the pull rod 15, so that the limiting block 13 extends through the through groove 4 into the interior of the limiting groove 12, which can realize the quick limiting of the hydraulic cylinder body 2. It is convenient to quickly disassemble and assemble during use or assembly, and has high practicality. Through the cooperation of the guide block 14 and the guide groove 11, the guide block 14 slides inside the guide groove 11 during the movement of the limiting block 13, which plays a guiding role and improves the overall stability. During use, because the rubber ring has good sealing performance, the design of the sealing ring 212 can prevent the oil inside the cylinder 201 from leaking out through the connection between the end cap 1 202 and the end cap 203 and the cylinder 201, thus improving the overall sealing performance. The design of three sealing rings 212 further improves the overall sealing performance.
