Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a quick-connect remote-controlled lithium battery hydraulic cylinder. Background Technology

[0002] Hydraulic cylinders, as actuators that convert hydraulic energy into mechanical energy, are widely used in engineering machinery, automation equipment, metallurgy, and various industrial production lines. They provide powerful linear thrust or pull through the extension and retraction of hydraulic rods.

[0003] In conventional applications, hydraulic cylinders need to be securely mounted on equipment frames or dedicated cylinders to withstand the enormous reaction forces generated during operation. Currently, the mainstream mounting methods mainly rely on flanges secured with high-strength bolts, or on threaded structures on the cylinder body that screw it into a mounting base.

[0004] This traditional method of fastening, relying on bolts or threads, while providing a reliable connection, reveals significant shortcomings during installation and disassembly. Operators need to use tools such as torque wrenches to tighten or loosen multiple bolts one by one, ensuring alignment and even force distribution. The entire process is time-consuming, labor-intensive, and cumbersome.

[0005] Especially in situations requiring frequent replacement, maintenance, or rapid adjustment of workstations (such as modular assembly lines or field rescue equipment), this slow installation method severely restricts work efficiency and increases equipment downtime for maintenance. Therefore, there is an urgent need for a hydraulic cylinder fixing structure that enables rapid installation, reliable locking, and convenient disassembly to meet the demands of efficient and flexible operations. Thus, this invention proposes a quick-connect remote-controlled lithium-ion hydraulic cylinder to address the shortcomings of existing technologies. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a quick-connect remote-controlled lithium-ion hydraulic cylinder, which aims to improve the problems of complex installation and fixing structure, time-consuming and labor-intensive disassembly and assembly, cumbersome operation, and serious restriction on work efficiency of some existing hydraulic cylinders.

[0007] This utility model provides a quick-connect remote-controlled lithium battery hydraulic cylinder, comprising: a cylinder, a hydraulic rod detachably installed in the cylinder, and a fixing mechanism.

[0008] The fixing mechanism is located inside the top of the hydraulic cylinder and is used to lock the hydraulic rod in the hydraulic cylinder. The fixing mechanism includes: a fixing post sleeved around the bottom end of the hydraulic rod; a triangular limiting block that is radially slidably disposed on the inner wall of the bottom end of the fixing post; a squeezing ball that is axially slidably disposed inside the fixing post, and the squeezing ball is used to abut against the inner inclined surface of the triangular limiting block; and auxiliary components.

[0009] Preferably, the auxiliary component includes a push pad disposed at the bottom end of the first fixed post, and a second fixed post connecting the extrusion ball and the push pad. The push pad contacts the inner wall of the cylinder when the first fixed post is inserted into the cylinder. The second fixed post transmits the reaction force received by the push pad to the extrusion ball, driving the extrusion ball to slide upwards along the inclined surface of the triangular limiting block, forcing the triangular limiting block to expand radially and engage with the inner wall of the cylinder. The fixing mechanism also includes a fixing ring, which is externally fixed to the inner wall of the top end of the cylinder. The auxiliary component also includes a sealing gasket, which is driven by the fixing ring and compressibly adheres to the outer side of the bottom end of the hydraulic rod.

[0010] Preferably, the auxiliary component further includes a control panel, a second connecting rod, a movable disk, and a first connecting rod; the bottom end of the second connecting rod is connected to the control panel, the movable disk is fixedly connected to the top end of the second connecting rod, and the first connecting rod connects the movable disk to the extrusion ball; the control panel is used to pull the extrusion ball upward through the second connecting rod, the movable disk, and the first connecting rod to release the extrusion on the triangular limiting block.

[0011] Preferably, the auxiliary component further includes a fixing plate, which is fixed to the first fixing column, and the second connecting rod is slidably disposed through the fixing plate.

[0012] Preferably, the fixing mechanism further includes a support plate and a reset rod; the support plate is radially fixed to the inner wall of the fixing column; the reset rod is fixed to the support plate and elastically abuts against the triangular limiting block, and is used to drive the triangular limiting block to reset inward by using elastic restoring force when the extrusion ball is released from extrusion.

[0013] Preferably, the auxiliary component further includes a retractable rod and a spring; the retractable rod is connected to the compression ball; the spring is sleeved on the outside of the retractable rod, and the spring is used to release elastic potential energy to push the retractable rod downward after the triangular limiting block is reset, so as to drive the compression ball to reset.

[0014] Preferably, the hydraulic cylinder further includes a buffer mechanism, which is fixedly connected to the top end of the hydraulic rod; the buffer mechanism includes a support chamber fixedly connected to the top end of the hydraulic rod, and a buffer plate slidably disposed on the top end of the support chamber.

[0015] Preferably, the buffer mechanism further includes a buffer pad, which is an elastic component. The buffer pad is located below the buffer plate and inside the support chamber, and is used to deform when the buffer plate is pressed down to absorb the impact force.

[0016] Preferably, the buffer mechanism further includes a connecting plate, a damping column, and a limiting plate; the connecting plate is fixedly connected to the bottom inner wall of the support chamber; the damping column is fixed to the top of the connecting plate; the limiting plate is disposed between the buffer pad and the damping column, and is used to apply the pressure transmitted by the buffer pad to the damping column, causing the damping column to undergo compression deformation; the bottom end of the hydraulic cylinder is fixedly connected to a base plate; a lithium battery pump station is fixedly connected to the top left side of the base plate; and a sensor is fixedly connected to the front bottom end of the hydraulic cylinder.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a fixing mechanism, uses the reaction force of the push pad when inserted to drive the squeezing ball to force the triangular limit block to unfold and engage the oil cylinder. By pulling the control plate, the squeezing ball is reset and the triangular limit block is retracted. This solves the problems of complex installation and fixing structure and time-consuming and labor-intensive disassembly and assembly of hydraulic cylinders in the prior art, and achieves the technical effects of quick insertion and removal, automatic locking, convenient operation and reliable fixing.

[0018] This invention solves the problem in the prior art where the hydraulic rod, when extended to its full position, experiences a rigid impact with an external device, which can easily lead to equipment damage. It achieves the technical effect of absorbing and dissipating impact energy step by step and protecting the equipment.

[0019] This invention solves the problem of insufficient sealing at the connection between the hydraulic cylinder and the mounting base in the prior art by setting a sealing gasket driven by a fixing ring. This ensures that the sealing gasket adheres to the outside of the bottom end of the hydraulic rod while the fixing mechanism is inserted and locked, thus achieving the technical effect of simultaneous installation and sealing and improved sealing performance at the connection.

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] Example: Reference Figures 1 to 8 This utility model provides a quick-connect remote-controlled lithium-ion hydraulic cylinder, which aims to solve the problems of complex installation and fixing structure, inconvenient disassembly and assembly, insufficient sealing at the connection, and rigid impact at the top of the hydraulic rod in the existing hydraulic cylinder.

[0024] like Figure 1 As shown, the quick-connect remote-controlled lithium-ion hydraulic cylinder includes a cylinder 1, a fixing mechanism 2, a hydraulic rod 3, and a buffer mechanism 4. The cylinder 1 serves as the mounting base for the entire device. The hydraulic rod 3 is detachably installed within the cylinder 1 and is used to achieve hydraulic extension and retraction. The fixing mechanism 2 is located inside the top of the cylinder 1 and is used to lock the hydraulic rod 3 to the cylinder 1.

[0026] The auxiliary component 29 includes a second fixed post 291, a push pad 292, a retractable rod 293, a fixed plate 294, a spring 295, a second connecting rod 296, a control plate 297, and a sealing gasket 298.

[0027] Reference Figure 2 , Figure 3 and Figure 4 In the fixing mechanism 2, fixing post 1 22 is sleeved around the bottom end of hydraulic rod 3. Triangular limiting block 23 is radially slidably disposed on the inner wall of the bottom end of fixing post 1 22. Extrusion ball 28 is axially slidably disposed inside fixing post 1 22, and extrusion ball 28 is used to abut against the inner inclined surface of triangular limiting block 23. Push pad 292 is disposed at the bottom end of fixing post 1 22. The upper end of fixing post 291 is connected to extrusion ball 28, and the lower end is connected to push pad 292. When fixing post 1 22 is inserted into cylinder 1, push pad 292 contacts the inner wall of cylinder 1 and generates a reaction force. The reaction force is transmitted to extrusion ball 28 through fixing post 291, driving extrusion ball 28 to slide upward along the inclined surface of triangular limiting block 23, forcing triangular limiting block 23 to expand radially and engage with the inner wall of cylinder 1.

[0028] Please refer to Figure 1 , Figure 5 and Figure 6 The buffer mechanism 4 includes a support chamber 41, a connecting plate 42, a damping column 43, a limiting plate 44, a buffer pad 45, and a buffer plate 46. The support chamber 41 is fixedly connected to the top of the hydraulic rod 3.

[0030] Reference Figure 2 and Figure 3 The fixing mechanism 2 also includes a reset rod 25, which is fixed to the support plate 24 and elastically abuts against the triangular limiting block 23. When the extrusion ball 28 is released from extrusion, the triangular limiting block 23 is driven to reset inward by the elastic restoring force.

[0031] Please refer to the following carefully. Figure 2 , Figure 3 and Figure 4The auxiliary component 29 also includes a release structure, specifically: a control panel 297, a second connecting rod 296, a movable disk 26, and a first connecting rod 27.

The control panel 297 is used to pull the compression ball 28 upward through the second connecting rod 296, the movable disk 26, and the first connecting rod 27 to release the compression assistance on the triangular limit block 23. Component 29 also includes a fixed plate 294, which is fixed to the first fixed post 22. The second connecting rod 296 slides through the fixed plate 294 to provide auxiliary support. Component 29 also includes a structure for resetting, specifically: a retractable rod 293 and a spring 295. The retractable rod 293 is connected to the compression ball 28, and the spring 295 is sleeved on the outside of the retractable rod 293. The spring 295 is used to release elastic potential energy to push the retractable rod 293 downward after the triangular limit block 23 is reset, so as to drive the compression ball 28 to reset. Please refer to [reference needed]. Figure 7 and Figure 8 The auxiliary component 29 also includes a sealing gasket 298, which is driven by the retaining ring 21 and compressibly adheres to the outside of the bottom end of the hydraulic rod 3.

[0032] Reference Figure 1 , Figure 5 and Figure 6 The hydraulic cylinder also includes a buffer mechanism 4, which is fixedly connected to the top of the hydraulic rod 3. The buffer mechanism 4 includes a support chamber 41, which is fixedly connected to the top of the hydraulic rod 3. The buffer mechanism 4 also includes a buffer plate 46, which is axially slidably disposed at the top of the support chamber 41. The buffer mechanism 4 also includes a buffer pad 45, which is an elastic component and is disposed below the buffer plate 46 and inside the support chamber 41. The buffer mechanism 4 also includes a connecting plate 42, which is fixedly connected to the inner wall of the bottom end of the support chamber 41. It also includes a damping column 43, which is fixed to the top of the connecting plate 42. The buffer mechanism 4 also includes a limiting plate 44, which is located between the buffer pad 45 and the damping column 43. The bottom end of the cylinder 1 is fixedly connected to a base plate 5, which provides support for subsequent components. The top left side of the base plate 5 is fixedly connected to a lithium battery pump station 6, which provides power support for the cylinder 1. The bottom front end of the cylinder 1 is fixedly connected to a sensor 7. The sensor 7 is started by remote control. The sensor 7 receives a signal and starts the lithium battery pump station 6. After the lithium battery pump station 6 is started, it provides power to the cylinder 1.

[0033] The implementation principle of this application embodiment is as follows: When the fixing mechanism 2 is inside the oil cylinder 1, the operator inserts the fixing ring 21 together with the fixing post 22 into the inner wall of the oil cylinder 1. During the insertion process, the push pad 292 at the bottom of the fixing post 22 first contacts the inner wall of the oil cylinder 1. The push pad 292 is subjected to an upward reaction force, which is transmitted to the extrusion ball 28 through the fixing post 291. The extrusion ball 28 slides upward along the inclined surface of the triangular limiting block 23. The upward sliding of the extrusion ball 28 causes the triangular limiting block 23 to be subjected to an outward component force and unfold. After the multiple triangular limiting blocks 23 unfold, they are tightly engaged with the inner wall of the oil cylinder 1, fixing the fixing post 22 inside the oil cylinder 1. At the same time, the sealing gasket 298 is attached to the outside of the bottom end of the hydraulic rod 3 under the drive of the fixing ring 21.

[0034] When the fixed mechanism 2 is released, the operator pulls the control panel 297 in the auxiliary component 29. The control panel 297 drives the moving plate 26 to move upward through the connecting rod 296. The fixed plate 294 provides guidance for the movement of the connecting rod 296. The moving plate 26 then drives the connecting rod 27 and the extrusion ball 28 to move upward synchronously. The extrusion ball 28 is released from the extrusion of the triangular limit block 23. The triangular limit block 23 is reset inward under the elastic restoring force of the reset rod 25 fixed on the support plate 24, releasing the jamming state with the inner wall of the cylinder 1. After completion, the retraction rod 293 and the spring 295 sleeved on its outside play their role. The spring 295 releases elastic potential energy to push the retraction rod 293 to move downward. The retraction rod 293 drives the extrusion ball 28 to reset to the bottom end of the fixed column 22.

[0035] When the hydraulic rod 3 drives the support chamber 41 to move upward and comes into contact with the device that needs support, the device exerts downward pressure on the buffer plate 46 at the top of the support chamber 41. After being subjected to pressure, the buffer plate 46 moves downward, pushing the buffer pad 45 below to move downward together. The buffer pad 45, as an elastic buffer component, deforms itself. As the buffer pad 45 continues to move downward, its bottom end drives the limiting plate 44 to move downward. The limiting plate 44 applies pressure to the multiple damping columns 43 below. The damping columns 43 are fixed to the top of the connecting plate 42. The damping columns 43 undergo compression deformation under pressure.
