Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring technology, specifically to a spring with a hydraulic energy storage mechanism. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. There are many types of springs. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and irregular springs.
[0003] When using a conventional spring for hydraulic energy storage, the spring must be placed inside the energy storage device. If the spring is not subjected to uniform force, it can easily cause the piston to tilt. If the piston tilts, hydraulic oil will leak out, which will greatly affect the stability of use and reduce the sealing effect of the energy storage device. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a spring with a hydraulic energy storage mechanism, which has advantages such as low oil leakage and high stability, and solves the problem of uneven spring force causing piston sleeve tilting and oil leakage.
[0006] (II) Technical Solution
[0007] To achieve the above-mentioned goals of being less prone to oil leakage and having high stability, this utility model provides the following technical solution: a spring with a hydraulic energy storage mechanism, including a base, three fixing plates fixedly connected to the upper surface of the base, each of the three fixing plates having a sliding groove on its inner surface, and a top cover fixedly connected to the upper surface of the three fixing plates.
[0008] Among them, a spring fixing plate is fixedly connected to the lower surface of the upper cover, a spring is fixedly connected to the lower surface of the spring fixing plate, and a hexagonal movable plate is fixedly connected to the lower end of the spring.
[0009] The outer surface of the hexagonal movable plate is fixedly connected with six vertical pulley fixing plates, and each corresponding pulley fixing plate is rotatably connected with two rubber pulleys.
[0010] Preferably, the six rubber pulleys are located on the upper and lower sides of the hexagonal movable plate, and the two corresponding rubber pulleys are slidably connected to the inner wall of the corresponding groove. A hydraulic cylinder is fixedly connected to the upper surface of the base, and a piston plate is provided inside the hydraulic cylinder.
[0011] Preferably, three sliding pillars are fixedly connected to the upper surface of the piston plate, and the upper ends of the three sliding pillars are fixedly connected to the lower surface of the hexagonal movable plate. A rubber piston sleeve is fixedly fitted on the outer surface of the piston plate.
[0012] Preferably, the outer surface of the rubber piston sleeve has two grooves, each groove containing a sealing ring, and the two sealing rings fit against the inner wall of the hydraulic cylinder.
[0013] Preferably, a cover plate is fixedly connected to the upper surface of the hydraulic cylinder, and the upper surface of the cover plate is provided with three sliding sealing holes, with each sliding column located in the corresponding sliding sealing hole and slidably connected to the sliding sealing hole.
[0014] Preferably, an oil pipe valve is fixedly connected to the outer surface of the hydraulic cylinder, and a pressure gauge is fixedly connected to the outer surface of the oil pipe valve.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a spring with a hydraulic energy storage mechanism, which has the following advantages:
[0017] 1. This spring, equipped with a hydraulic energy storage mechanism, injects hydraulic oil into the hydraulic cylinder through an oil pipe valve. As the hydraulic oil increases within the cylinder, it exerts an upward force on the rubber piston sleeve, causing the piston plate on the piston sleeve to move upward within the cylinder. As the piston plate moves upward, it slides upward along the axis of the sliding sealing hole via three sliding columns, simultaneously moving the hexagonal moving plate upward. When the hexagonal moving plate moves upward, it causes the rubber pulley on it to move upward along the vertical direction of the three sliding grooves. This upward movement of the hexagonal moving plate applies an upward force to the fixed spring, compressing and storing energy. The pulley fixing plate is perpendicular to the hexagonal moving plate, ensuring the verticality of the hexagonal moving plate during its movement. This allows the spring to receive even force, preventing uneven force on the spring from causing the rubber piston sleeve to tilt and leak oil. It also ensures the sealing effect of the rubber piston sleeve and improves operational stability.
[0018] The spring equipped with a hydraulic energy storage mechanism, through the setting of two sealing rings and three sliding sealing holes, can further prevent oil leakage during use, avoiding unnecessary trouble. The setting of three sets of fixed plates, sliding sealing holes, sliding columns and rubber pulleys makes the overall structure of the utility model more stable and solid, avoiding the problem of easy damage due to structural instability during use.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3This utility model provides a new technical solution: a spring with a hydraulic energy storage mechanism, including a base 1, three fixing plates 2 fixedly connected to the upper surface of the base 1, each of the three fixing plates 2 having a sliding groove 13 on its inner surface, an upper cover 3 fixedly connected to the upper surface of the three fixing plates 2, a spring fixing plate 16 fixedly connected to the lower surface of the upper cover 3, a spring 15 fixedly connected to the lower surface of the spring fixing plate 16, a hexagonal moving plate 11 fixedly connected to the lower end of the spring 15, and six vertical pulley fixing plates 12 fixedly connected to the outer surface of the hexagonal moving plate 11. Two rubber pulleys 14 are rotatably connected between each corresponding pulley fixing plate 12. The six rubber pulleys 14 are located on the upper and lower sides of the hexagonal moving plate 11, and the corresponding two rubber pulleys 14 are connected to each other. Each of the four components is slidably connected to the inner wall of the corresponding slide groove 13. A hydraulic cylinder 4 is fixedly connected to the upper surface of the base 1. A piston plate 8 is installed inside the hydraulic cylinder 4. Three sliding columns 7 are fixedly connected to the upper surface of the piston plate 8. The upper ends of the three sliding columns 7 are fixedly connected to the lower surface of the hexagonal moving plate 11. A rubber piston sleeve 9 is fixedly fitted on the outer surface of the piston plate 8. Two grooves are opened on the outer surface of the rubber piston sleeve 9. A sealing ring 10 is installed in each groove. The two sealing rings 10 fit against the inner wall of the hydraulic cylinder 4. A cover plate 5 is fixedly connected to the upper surface of the hydraulic cylinder 4. Three sliding sealing holes 6 are provided on the upper surface of the cover plate 5. The sliding columns 7 are all located in the corresponding sliding sealing holes 6 and are slidably connected to the sliding sealing holes 6. An oil pipe valve is fixedly connected to the outer surface of the hydraulic cylinder 4. 17. A pressure gauge 18 is fixedly connected to the outer surface of the oil pipe valve 17. During use, hydraulic oil is injected into the hydraulic cylinder 4 through the oil pipe valve 17. As the hydraulic oil increases in the hydraulic cylinder 4, it applies an upward force to the rubber piston sleeve 9, causing the piston plate 8 on the rubber piston sleeve 9 to move upward within the hydraulic cylinder 4. When the piston plate 8 moves upward, it slides upward along the axis of the sliding sealing hole 6 via three sliding columns 7, simultaneously causing the hexagonal moving plate 11 on it to move upward. When the hexagonal moving plate 11 moves upward, it causes the rubber pulley 14 on it to move upward along the vertical direction of the three sliding grooves 13. When the hexagonal moving plate 11 moves upward, it applies an upward force to the spring 15 fixed on it. The force allows the spring 15 to compress and store energy. The fixed plate 12 and the hexagonal moving plate 11 are placed perpendicularly, ensuring the verticality of the hexagonal moving plate 11 during its vertical movement. This ensures the spring 15 receives even force, preventing uneven force on the spring 15 and thus avoiding the problem of oil leakage caused by tilting of the rubber piston sleeve 9. It also ensures the sealing effect of the rubber piston sleeve 9 and improves its stability. The two sealing rings 10 and three sliding sealing holes 6 further prevent oil leakage during use, avoiding unnecessary trouble. The fact that there are three sets of fixed plates 2, sliding sealing holes 6, sliding columns 7, and rubber pulleys 14 makes the overall structure of this utility model more stable and robust.This avoids the problem of easy damage due to structural instability during use.
[0025] Working principle: During use, hydraulic oil is injected into the hydraulic cylinder 4 through the oil pipe valve 17. As the hydraulic oil increases in the hydraulic cylinder 4, it applies an upward force to the rubber piston sleeve 9, which in turn drives the piston plate 8 on it to move upward within the hydraulic cylinder 4. When the piston plate 8 moves upward, it slides upward along the axis of the sliding sealing hole 6 through the three sliding columns 7, which in turn drives the hexagonal moving plate 11 on it to move upward. When the hexagonal moving plate 11 moves upward, it drives the rubber pulley 14 on it to move upward along the vertical direction of the three sliding grooves 13. When the hexagonal moving plate 11 moves upward, it applies an upward force to the spring 15 fixed on it, which compresses and stores energy. The pulley fixing plate 12 is set to be placed perpendicular to the hexagonal moving plate 11, which effectively ensures the verticality of the hexagonal moving plate 11 when it moves up and down, and allows the spring 15 to be fully and evenly stressed.
