[0002] A spring is a mechanical component that uses elasticity to function. Parts made of elastic material deform under external force and return to their original shape when the force is removed. They are generally made of spring steel. There are many different types of springs, including coil springs, scroll springs, leaf springs, and special-shaped springs. Some equipment uses springs for shock absorption.

[0003] According to a Chinese patent with the authorization announcement number CN215762984U, a spring assembly that can extend the service life of a spring is disclosed, including a spring, a bottom tube is provided on the outside of the spring, a waterproof cloth is provided on the top of the bottom tube, a ring is provided on the top of the waterproof cloth, the waterproof cloth is adhesively connected to the ring and the bottom tube, an exhaust check valve is provided on the waterproof cloth, and an air intake check valve is provided on one side of the exhaust check valve. The device is easy to use by providing the waterproof cloth and the exhaust check valve. The waterproof cloth is waterproof and dustproof, thereby preventing dust and water in the external environment from eroding the spring. Although the above device waterproofs and dustproofs the spring by the waterproof cloth and the exhaust check valve, thereby achieving the effect of extending the service life of the spring, the spring in the device is easily squeezed and frictionally affected by the movable screen plate under repeated compression and reset working conditions, resulting in wear and tear, which reduces the service life of the spring.

[0004] Based on this, it is necessary to design a spring assembly that can reduce spring wear and extend the service life. Utility Model Content

[0011] As a preferred technical solution of the present invention, a collecting frame is slidably connected to the middle of the bottom plate.

[0012] Beneficial effects: 1.

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0025] Embodiment: A spring assembly with extended service life, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, it includes a base plate 1, a hollow guide cylinder 2, a movable screen plate 3, an oil storage ring 8, a second connecting pipe 12, an oil inlet pipe 11 and an elastic member 51. The top of the base plate 1 is fixedly connected to the hollow guide cylinder 2, and the hollow guide cylinder 2 is slidably connected to the movable screen plate 3. One end of the movable screen plate 3 extends into the interior of the hollow guide cylinder 2. An elastic member 51 is provided inside the hollow guide cylinder 2. The top of the base plate 1 is fixedly connected to the oil storage ring 8, and the oil storage ring 8 is connected to the oil inlet pipe 11 through the second connecting pipe 12. The oil inlet pipe 11 extends into the interior of the hollow guide cylinder 2 through the slide groove provided in the hollow guide cylinder 2. Here, the oil storage ring 8 is provided on the outside of the hollow guide cylinder 2, and the lubricating oil in the oil storage ring 8 flows to the oil inlet pipe 11 through the second connecting pipe 12, and the lubricating oil is then discharged from the oil inlet pipe 11, so that the lubricating oil enters the interior of the hollow guide cylinder 2. As a preferred method, the elastic member 51 described in this embodiment is preferably a spring.

[0026] like Figure 3 and Figure 4As shown, a group of annular slide rails 4 are provided inside the hollow guide cylinder 2, the upper annular slide rail 4 is fixedly connected to the bottom of the movable screen plate 3, and the lower annular slide rail 4 is fixedly connected to the top of the base plate 1. An arc-shaped slider 5 is slidably connected inside the annular slide rail 4, and an elastic member 51 is provided between the two arc-shaped sliders 5. The oil inlet pipe 11 is connected to the elastic member 51 through a through hole provided in the arc-shaped slider 5. Here, the design of the annular slide rail 4 and the arc-shaped slider 5 makes the elastic member 51 twist and slide into the annular slide rail 4 during the compression process, thereby increasing the force area of the elastic member 51 and reducing wear to a certain extent.

[0027] like Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown, a second cylinder body 9 is installed on the top of the oil storage ring 8, and a second piston 10 is slidably connected inside the second cylinder body 9. A first cylinder body 6 is installed in the hollow guide cylinder 2, and a first piston 7 is slidably connected to the first cylinder body 6. One end of the first piston 7 extends out of the first cylinder body 6, and the extended end of the first piston 7 is fixedly connected to the movable screen plate 3. The second cylinder body 9 is connected to the first cylinder body 6 through a first connecting pipe 13.

[0028] like Figure 8 As shown, a collecting frame 14 is slidably connected to the middle of the base plate 1. Here, a plurality of through holes are evenly distributed on the annular slide rail 4. When excess lubricating oil flows along the elastic member 51 to the annular slide rail 4, the lubricating oil passes through the through holes and falls into the collecting frame 14, thereby collecting the excess lubricating oil. The lubricating oil is recycled by sliding the collecting frame 14 outward to reduce costs. Here, when the first piston 7 slides upward, a one-way valve is provided on one side of the first cylinder body 6. The first cylinder body 6 extracts air outside the first cylinder body 6 through the one-way valve. When the first piston 7 slides downward, the first piston 7 compresses the internal space of the first cylinder body 6, so that the air is squeezed and sent to the second cylinder body 9 through the first connecting pipe 13.

[0029] When using this spring assembly, a downward force is applied to the movable screen plate 3, causing the movable screen plate 3 to squeeze the elastic member 51, and through the recovery characteristics of the elastic member 51, the movable screen plate 3 is pushed back to its initial position, thereby relying on the compression and recovery of the elastic member 51 to achieve the working effect of the assembly. During operation, when the movable screen plate 3 slides up and down, it drives the first piston 7 fixed to the movable screen plate 3 to slide up and down, so that when the first piston 7 slides upward, the first cylinder 6 extracts the air outside the first cylinder 6 through the one-way valve provided. When the first piston 7 slides downward, the first piston 7 compresses the internal space of the first cylinder 6, so that the air is squeezed and sent to the second cylinder 9 through the first connecting pipe 13. The air then enters the interior of the second cylinder 9 and pushes the second piston 10 inside the second cylinder 9 to slide downward. By pushing the second piston 10, air is injected into the oil storage ring 8, forming a pressurized effect on the interior of the oil storage ring 8, so that the lubricating oil inside the oil storage ring 8 flows to the oil inlet pipe 11 under the influence of pressure. When the lubricating oil enters the through hole of the arc-shaped slider 5 through the oil inlet pipe 11, the lubricating oil contacts the elastic member 51 and flows downward along the elastic member 51, thereby forming an oil layer on the surface of the elastic member 51, keeping the surface of the elastic member 51 smooth, reducing friction and wear, and also playing an anti-corrosion protection role, thereby extending the service life of the elastic member 51.

[0030] It should be understood that the above description is for exemplary purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will fall within the scope of the claims herein.
