Description

Technical Field

[0001] The utility model relates to the technical field of elastic elements, in particular to a corrugated spring with high compressive strength. Background Art

[0002] The corrugated spring, simply called wave spring, is an elastic element with several peaks and valleys on a thin metal ring. The corrugated spring is particularly suitable for applications that require weight reduction and applications restricted by a small installation space. The whole corrugated spring is usually welded by a corrugated ring with peaks and valleys.

[0003] Chinese Patent with publication number CN216589715U discloses a corrugated spring with high compressive strength, including a corrugated spring body. The corrugated spring body includes a pair of flat rings and several corrugated rings. A plurality of node fixators are fixed between adjacent corrugated rings. The node fixator includes a base, a pair of convex columns and a pair of water droplet columns. An elastic increasing sheet is tightly welded between two longitudinally adjacent node fixators. For this corrugated spring with high compressive strength, through the provided node fixators, the dislocation of the corrugated rings caused by loosening and breaking at the connection can be prevented. At the same time, through the provided elastic increasing sheet, the overall elasticity of the corrugated spring body is enhanced, which helps the corrugated spring body to recover after being compressed and prevents the corrugated spring body from losing its effect.

[0004] However, the above disclosed solution has the following deficiencies: The existing corrugated spring cannot withstand high pressure and is prone to breakage under high pressure, resulting in damage to the corrugated spring. Summary of the Utility Model

[0005] The purpose of the utility model is to address the problem that the corrugated spring is prone to breakage under high pressure in the background art, and to propose a corrugated spring with high compressive strength.

[0006] The technical solution of the utility model: A corrugated spring with high compressive strength includes a corrugated spring body and a fixing ring arranged at the end of the corrugated spring body; it further includes:

[0007] A compression resistance mechanism, arranged on the corrugated spring body, used to fix the corrugated spring body through the movement of hydraulic oil;

[0008] And a lubrication mechanism, arranged inside the corrugated spring body, used to supplement lubricating oil for the corrugated spring body when it bears high pressure.

[0009] The compression resistance mechanism includes a telescopic tube one, a fixing tube one, a connecting tube, a fixing tube two and a pressure relief component;

[0010] The telescopic tube one is arranged on the corrugated spring body, the fixing tube one is arranged at the bottom of the telescopic tube one, the connecting tube is arranged on the side of the fixing tube one, and the fixing tube two is arranged at the end of the connecting tube away from the fixing tube one;

[0011] The pressure relief component is arranged inside the first fixed pipe and is used to make the wave spring body more resistant to pressure.

[0012] The pressure relief component includes the first end cap, the second end cap, the first spring, the second spring, the first sealing push plate and the second sealing push plate;

[0013] The first end cap is arranged at the top of the first fixed pipe, the second end cap is arranged at the top of the second fixed pipe, the first spring is arranged at the bottom of the first end cap, the first sealing push plate is arranged at one end of the first spring away from the first end cap, the second spring is arranged at the bottom of the second end cap, and the second sealing push plate is arranged at one end of the second spring away from the second end cap.

[0014] The lubrication mechanism includes a power component and a lubrication component;

[0015] The power component is arranged inside the wave spring body and is used to provide power for the lubrication component;

[0016] The lubrication component is arranged outside the power component and is used to spray lubricating oil when the wave spring bears high pressure.

[0017] The power component includes a pressing plate, a connecting frame, a fixing block, a piston, a third spring and a second telescopic pipe;

[0018] The pressing plate is arranged inside the fixing ring and is located at the top of the wave spring body. The connecting frame is arranged inside the fixing ring and is located at the bottom of the wave spring body. The fixing block is located below the pressing plate and is at the axis center of the pressing plate. The piston is arranged at the bottom of the fixing block, the second telescopic pipe is arranged at the bottom of the piston, and the third spring is arranged outside the second telescopic pipe.

[0019] The lubrication component includes a storage box, an oil outlet pipe and a nozzle;

[0020] The storage box is arranged on the top of the connecting frame, the oil outlet pipe is arranged on the side of the storage box, and the nozzle is arranged at one end of the oil outlet pipe away from the storage box.

[0021] Compared with the prior art, the utility model has the following beneficial technical effects:

[0022] 1. Through the setting of the pressure resistance mechanism, when the wave spring resists pressure and the first spring and the second spring drive the first sealing push plate and the second sealing push plate to move, it will push the hydraulic oil to move so as to relieve pressure. In this way, the vibration energy in the system can be effectively absorbed and dispersed. For the wave spring, it means that it can reduce the additional stress generated by vibration. Although the wave spring itself has a certain vibration damping performance, the movement of the hydraulic oil can further enhance this effect, thereby prolonging the service life of the wave spring. At the same time, the flow of the oil can be used as a buffer medium to slow down the instantaneous stress change of the wave spring when it is impacted, and avoid the spring from being damaged due to sudden excessive load.

[0023] 2. Through the setting of the lubrication mechanism, when the wave spring bears high pressure, it will be pressed down to a certain extent, thereby driving the piston to squeeze the lubricating oil so that it sprays from the nozzle to the fixing ring. This can significantly reduce the friction between the spring and adjacent components during movement, thereby reducing wear. This not only helps to maintain the original shape and elasticity of the spring, but also extends its service life. It can also absorb and conduct the heat generated during the operation of the wave spring, helping to reduce the working temperature and prevent performance degradation or damage caused by overheating. And it can form a protective film on the surface of the wave spring to prevent rust and corrosion caused by external factors such as air, water droplets, and corrosive gases.

Detailed Description of the Embodiment

[0030] Embodiment 1

[0031] As Figures 1 - 3 shown, a highly compressive wave spring proposed by the present utility model includes a wave spring body 1, a fixing ring 2 arranged at the end of the wave spring body 1, a compressive mechanism, and a lubrication mechanism:

[0032] The compressive mechanism is arranged on the wave spring body 1 to fix the wave spring body 1 through the movement of hydraulic oil;

[0033] The lubrication mechanism is arranged inside the wave spring body 1 to supplement lubricating oil for it when the wave spring body 1 bears high pressure.

[0034] The pressure-resistant mechanism includes a first telescopic tube 301, a first fixed tube 302, a connecting tube 303, a second fixed tube 304, and a pressure relief component;

[0035] The first telescopic tube 301 is arranged on the waveform spring body 1, the first fixed tube 302 is arranged at the bottom of the first telescopic tube 301, the connecting tube 303 is arranged on the side of the first fixed tube 302, and the second fixed tube 304 is arranged at one end of the connecting tube 303 away from the first fixed tube 302;

[0036] The pressure relief component is arranged inside the first fixed tube 302 to make the waveform spring body 1 more pressure-resistant.

[0037] The pressure relief component includes a first end cover 305, a second end cover 306, a first spring 307, a second spring 310, a first sealing push plate 308, and a second sealing push plate 309;

[0038] The first end cover 305 is arranged on the top of the first fixed tube 302, the second end cover 306 is arranged on the top of the second fixed tube 304, the first spring 307 is arranged at the bottom of the first end cover 305, the first sealing push plate 308 is arranged at one end of the first spring 307 away from the first end cover 305, the second spring 310 is arranged at the bottom of the second end cover 306, the second sealing push plate 309 is arranged at one end of the second spring 310 away from the second end cover 306. The first fixed tube 302 and the second fixed tube 304 are both filled with hydraulic oil. When the waveform spring is in use, since the first telescopic tube 301 is located on the top of the first fixed tube 302 and contacts the waveform spring body 1, the waveform spring body 1 will squeeze the first telescopic tube 301, thereby squeezing the first spring 307. The first spring 307 pushes the sealing push plate so that the hydraulic oil in the first fixed tube 302 flows through the connecting tube 303 into the second fixed tube 304. The increase in the hydraulic oil in the second fixed tube 304 will squeeze the second spring 310 through the second sealing push plate 309, thereby realizing the conversion of energy and converting the pressure to the inside of the first fixed tube 302 and the second fixed tube 304, thereby increasing the pressure-resistant ability of the waveform spring body 1.

[0039] Embodiment 2

[0040] As Figures 4 - 5 shown, a highly pressure-resistant waveform spring proposed by the present utility model, compared with Embodiment 1, this embodiment details the structure of the lubricating mechanism:

[0041] The lubrication mechanism includes a power component and a lubrication component; the power component is arranged inside the corrugated spring body 1 to provide power for the lubrication component; the lubrication component is arranged outside the power component to spray lubricating oil when the corrugated spring bears high pressure. The power component includes a pressing plate 401, a connecting frame 402, a fixing block 405, a piston 404, a spring three 407 and a telescopic tube two 406; the pressing plate 401 is arranged inside the fixing ring 2 and at the top of the corrugated spring body 1, the connecting frame 402 is arranged inside the fixing ring 2 and at the bottom of the corrugated spring body 1, the fixing block 405 is located below the pressing plate 401 and at the axis center of the pressing plate 401, the piston 404 is arranged at the bottom of the fixing block 405, the telescopic tube two 406 is arranged at the bottom of the piston 404, the spring three 407 is arranged outside the telescopic tube two 406. When the corrugated spring body 1 bears high pressure, it will continuously drive the pressing plate 401 to move. When the pressing plate 401 touches the fixing block 405, it drives the fixing block 405 to press down, and the fixing block 405 drives the piston 404 to press down. The lubrication component includes a storage box 403, an oil outlet pipe 408 and a nozzle 409; the storage box 403 is arranged on the top of the connecting frame 402, the oil outlet pipe 408 is arranged on the side of the storage box 403, there are two oil outlet pipes 408 and they are connected to the inside of the storage box 403, the nozzle 409 is arranged at one end of the oil outlet pipe 408 away from the storage box 403. When the piston 404 moves downward, it will squeeze the lubricating oil in the storage box 403, thus squeezing these lubricating oils into the oil outlet pipe 408. A pressure switch is arranged inside the nozzle 409, and the valve will only open when a certain pressure value is reached, to avoid leakage of lubricating oil under normal conditions. The squeezed lubricating oil is sprayed out through the nozzle 409, and the oil outlet of the nozzle 409 points to the position where the pressing plate 401 is pressed down. In this way, lubricating oil can be sprayed on the connection between the top of the pressing plate 401 and the pressing part, reducing the friction coefficient and resistance, thereby reducing energy loss and improving the compressive capacity.

[0042] In summary, when the utility model is in use, after placing a heavy object on the corrugated spring, the corrugated spring compresses, thereby squeezing the first telescopic tube 301. The first telescopic tube 301 squeezes the first spring 307, and the first spring 307 pushes the sealing push plate so that the hydraulic oil in the first fixed tube 302 flows through the connecting tube 303 into the second fixed tube 304. The increase in the hydraulic oil in the second fixed tube 304 will squeeze the second spring 310 through the second sealing push plate 309, thereby realizing the conversion of energy, converting the pressure to the inside of the first fixed tube 302 and the second fixed tube 304, so as to increase the compressive capacity of the corrugated spring body 1. When the corrugated spring body 1 bears high pressure, it will continuously drive the pressing plate 401 to move. When the pressing plate 401 contacts the fixed block 405, it drives the fixed block 405 to press down. The fixed block 405 drives the piston 404 to press down. When the piston 404 moves downward, it will squeeze the lubricating oil in the storage box 403, thereby squeezing these lubricating oils toward the oil outlet pipe 408. A pressure switch is provided inside the nozzle 409, and the valve will only be opened when a certain pressure value is reached, avoiding the leakage of lubricating oil under normal conditions. The squeezed lubricating oil is sprayed out through the nozzle 409, and the oil outlet of the nozzle 409 points to the position where the pressing plate 401 is pressed down. In this way, the lubricating oil can be sprayed on the top of the pressing plate 401 and the connection of the pressing part, reducing the friction coefficient and resistance, thereby reducing energy loss and increasing the compressive capacity.

Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
