[0019] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0020] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0021] As Figures 1-9 shown, an anti-friction and shock-absorbing butterfly spring includes an outer column 1. An anti-friction and shock-absorbing mechanism 2 is arranged inside the outer column 1. The anti-friction and shock-absorbing mechanism 2 is used for anti-friction and shock absorption of the butterfly spring. A driving mechanism 3 is arranged at the top of the outer column 1. One-way liquid through mechanisms 4 are arranged at both ends of the bottom of the driving mechanism 3. The two one-way liquid through mechanisms 4 are arranged in opposite positions relative to the sealing seat 6. The one-way liquid through mechanism 4 is used for one-way liquid through. A plurality of cleaning mechanisms 5 are arranged inside the driving mechanism 3. The driving mechanism 3 can drive the plurality of cleaning mechanisms 5 to rotate.

[0022] The anti-friction and shock-absorbing mechanism 2 includes a receiving groove 201 which provides an installation position and whose interior is filled with lubricating oil. The receiving groove 201 is opened inside the outer column 1. A movable column 202 is slidably connected to the middle of the outer column 1, and the movable column 202 provides an installation position. A plurality of butterfly-shaped elastic pieces 203 are slidably connected to the outside of the movable column 202. The movable column 202 can limit the movement track of the butterfly-shaped elastic pieces 203, and the butterfly-shaped elastic pieces 203 can provide elastic force. Liquid through holes 204 are opened in both inner sides of the butterfly-shaped elastic pieces 203, and the liquid through holes 204 can pass liquid. Liquid through grooves 205 are opened in both inner sides of the outer column 1, and the liquid through grooves 205 can pass liquid. A plurality of communication holes 206 are opened in the inner walls on both sides of the outer column 1. A top column 207 is fixedly connected to the top of the top butterfly-shaped elastic piece 203, and the bottom of the top column 207 is fixedly connected to the top of the movable column 202. The bottom of the bottom butterfly-shaped elastic piece 203 is fixedly connected to the bottom inner wall of the receiving groove 201. The butterfly-shaped elastic pieces 203 are slidably connected inside the receiving groove 201. The outside of the top column 207 is slidably connected to the top of the outer column 1. The communication holes 206 are communicated with the receiving groove 201. A sealing ring 7 is fixedly connected to the top of the outer column 1. The outside of the top column 207 is slidably connected to the inside of the sealing ring 7. After the top column 207 is squeezed, it can drive the movable column 202 to move downward, and can use the top column 207 to squeeze the butterfly-shaped elastic pieces 203, causing the butterfly-shaped elastic pieces 203 to deform. Under the reaction force of the butterfly-shaped elastic pieces 203, the butterfly-shaped elastic pieces 203 have elasticity. When the butterfly-shaped elastic pieces 203 deform, the lubricating oil inside the butterfly-shaped elastic pieces 203 can flow out from the inside of the liquid through holes 204. At the same time, when the liquid in the receiving groove 201 increases, it will enter the inside of the liquid through groove 205 through the communication holes 206, and then enter the driving mechanism 3 through the liquid through groove 205. When the butterfly-shaped elastic pieces 203 rebound, they can drive the top column 207 to move upward, and then can drive the movable column 202 to move upward, squeezing the liquid into the inside of the liquid through groove 205, and passing the liquid inside the liquid through groove 205 into the inside of the receiving groove 201 through the communication holes 206, and then entering the inside of the butterfly-shaped elastic pieces 203 through the liquid through holes 204. It realizes that the liquid can flow when the butterfly-shaped elastic pieces 203 are squeezed and when the butterfly-shaped elastic pieces 203 recover, and then can lubricate the butterfly-shaped elastic pieces 203, playing a role in reducing friction. At the same time, because the holes of the communication holes 206 are relatively small, the flow rate of the liquid can be limited, and then the butterfly-shaped elastic pieces 203 can be prevented from bouncing suddenly and impacting the inside of the outer column 1, playing a role in shock absorption.

[0023] The driving mechanism 3 includes a fixed ring 301 which provides an installation position. The bottom of the fixed ring 301 is fixedly connected to the top of the outer column 1. The top of the fixed ring 301 is fixedly connected with an installation ring 302 which provides an installation space. The inner side of the installation ring 302 is rotatably connected with a rotating ring 303. On the inner side of the installation ring 302, a fixed connection is made to an inner ring 305 on the outer part of the rotating ring 303. On the side of the inner ring 305 away from the rotating ring 303, a plurality of blades 306 are fixedly connected. Under the action of the flowing liquid, the blades 306 can drive the inner ring 305 and the rotating ring 303 to rotate. On the side of the rotating ring 303 away from the inner ring 305, a fixed connection is made to an outer ring 304. The outer ring 304 and the inner ring 305 can play a role in limiting. On both sides of the outside of the installation ring 302, liquid supply pipes 307 are fixedly connected. The liquid supply pipes 307 can let the liquid in. Inside the bottom end of the outer column 1, a liquid storage groove 309 is opened. Inside the liquid storage groove 309, a movable plug 308 is slidably connected. The inside of the liquid storage groove 309 is also filled with liquid and is divided into two layers with the movable plug 308 as the boundary. The top of the movable plug 308 is fixedly connected to the bottom of the movable column 202. When the movable plug 308 moves downward, the liquid in the space below the movable plug 308 in the liquid storage groove 309 will enter the inside of one of the liquid supply pipes 307 through one of the one-way liquid supply mechanisms 4, and then the liquid can flow inside the installation ring 302, so as to drive the blades 306 to rotate. After the blades 306 rotate, they can drive the inner ring 305 to rotate. After the inner ring 305 rotates, it can drive the rotating ring 303 and the outer ring 304 to rotate, and then can drive the cleaning mechanism 5 to rotate. The cleaning mechanism 5 is used to scrape off the dust and impurities attached to the top column 207, preventing them from entering the inside of the receiving groove 201 as the top column 207 moves up and down continuously for a long time, which may cause an increase in the frictional force between the butterfly-shaped elastic piece 203 and the inner wall of the receiving groove 201 and lead to damage to the butterfly-shaped elastic piece 203.

[0024] The one-way liquid passage mechanism 4 includes an installation cylinder 401 which provides an installation position. On the side of the two installation cylinders 401 away from the outer column 1, they are fixedly connected to the bottom of the liquid passage pipe 307. A sealing circular block 405 is slidably connected inside the installation cylinder 401. The sealing circular block 405 plays a role in limiting. A plurality of holes 406 are formed inside the outer edge of the sealing circular block 405, and the holes 406 can pass liquid. A stabilizing column 403 is fixedly connected to the middle of the sealing circular block 405. The stabilizing column 403 can improve the stability of the movement of the sealing circular block 405. A first spring 404 is sleeved outside the stabilizing column 403. A fixing frame 402 is slidably connected to the outside of the stabilizing column 403. The outer periphery of the fixing frame 402 is fixedly connected inside the installation cylinder 401. A limiting disc 407 is fixedly connected to the side of the stabilizing column 403 away from the sealing circular block 405. A sealing seat 6 is fixedly connected to the side of the installation cylinder 401 away from the liquid passage pipe 307. On the side of the two sealing seats 6 away from the liquid passage pipe 307, they are respectively fixedly connected to both sides of the outer column 1. The inside of the installation cylinder 401 is connected to the bottom of the liquid filling groove 309. One end of the first spring 404 is fixedly connected to the side of the sealing circular block 405 close to the limiting disc 407, and the other end of the first spring 404 is fixedly connected to the side of the fixing frame 402 close to the sealing circular block 405. When the movable plug 308 moves downward, it can then squeeze the liquid, causing the liquid to push one of the sealing circular blocks 405 to move away from the outer column 1. When the holes 406 on the sealing circular block 405 are no longer blocked by the installation cylinder 401, the first spring 404 can be compressed, allowing the liquid to enter the inside of the installation cylinder 401 through the holes 406 and be discharged through the liquid passage pipe 307. When the movable plug 308 moves upward, a suction force is generated in the space below the movable plug 308 inside the liquid filling groove 309. At this time, one of the sealing circular blocks 405 quickly moves toward the outer column 1 under the dual action of the first spring 404 and the suction force, and then the holes 406 can be blocked by the installation cylinder 401. At this time, the liquid cannot enter the inside of the liquid filling groove 309 from one of the installation cylinders 401. When the movable plug 308 moves downward, the other sealing circular block 405 will be pressed tightly against the inner side of the installation cylinder 401 under the action of the liquid pressure, so that the holes 406 can be blocked by the inner side of the installation cylinder 401. When liquid enters the other liquid passage pipe 307, it will push the sealing circular block 405 toward the outer column 1 under the action of the liquid pressure, so that the other sealing circular block 405 can move toward the outer column 1, and then the holes 406 on the other sealing circular block 405 will no longer be blocked by the installation cylinder 401, so that the liquid can enter the space below the movable plug 308 in the liquid filling groove 309 from the inside of the other installation cylinder 401, thus realizing the one-way movement of the liquid in the space composed of the two liquid passage pipes 307 and the installation ring 302.Subsequently, the rotating ring 303 can drive the cleaning mechanism 5 to rotate, and then the dust on the top column 207 can be scraped off.

[0025] The cleaning mechanism 5 includes a mounting shell 501 which provides a mounting position. The outside of multiple mounting shells 501 is fixedly connected to the inside of the rotating ring 303. A second spring 502 is arranged inside the mounting shell 501. A limiting circular block 503 is slidably connected inside the mounting shell 501, and the limiting circular block 503 has a limiting function. A movable rod 504 is fixedly connected to the side of the limiting circular block 503 away from the second spring 502, and the movable rod 504 plays a connecting role. A cleaning brush 505 is fixedly connected to the side of the movable rod 504 away from the limiting circular block 503. The cleaning brush 505 can clean the outer surface of the top column 207. One end of the second spring 502 is fixedly connected to the inner side of the mounting shell 501, and the other end of the second spring 502 is fixedly connected to the end of the limiting circular block 503 away from the movable rod 504. When the cleaning brush 505 abuts against the outer wall of the top column 207, the movable rod 504 and the limiting circular block 503 compress the second spring 502. Therefore, the reaction force of the second spring 502 can be used to give the limiting circular block 503 and the movable rod 504 a force towards the top column 207, and then the cleaning brush 505 can be tightly abutted against the outside of the top column 207, so that the dust on the top column 207 can be scraped off.

[0026] Working principle: After the top column 207 is squeezed, it can drive the movable column 202 to move downward, and can use the top column 207 to squeeze the butterfly-shaped elastic piece 203, causing the butterfly-shaped elastic piece 203 to deform. Under the reaction force of the butterfly-shaped elastic piece 203, the butterfly-shaped elastic piece 203 has elasticity. When the butterfly-shaped elastic piece 203 deforms, the lubricating oil inside the butterfly-shaped elastic piece 203 can flow out from the inside of the liquid through-hole 204. At the same time, when the liquid in the accommodating groove 201 increases, it will enter the inside of the liquid through-groove 205 through the communication hole 206, and enter the liquid filling groove 309 located in the upper half of the movable plug 308 through the liquid through-groove 205. At this time, since the movable plug 308 moves downward, the space in the upper half of the movable plug 308 in the liquid filling groove 309 can increase. At the same time, as the movable plug 308 moves, suction can be generated, causing the excess liquid in the liquid through-groove 205 to enter the upper half of the movable plug 308 in the liquid filling groove 309. When the butterfly-shaped elastic piece 203 rebounds, it can drive the top column 207 to move upward, and then drive the movable column 202 and the movable plug 308 to move upward. Then, the liquid in the upper half of the movable plug 308 can be squeezed into the inside of the liquid through-groove 205, and the liquid in the liquid through-groove 205 can be introduced into the inside of the accommodating groove 201 through the communication hole 206, and then enter the inside of the butterfly-shaped elastic piece 203 through the liquid through-hole 204. It realizes that the liquid can flow when the butterfly-shaped elastic piece 203 is squeezed and when the butterfly-shaped elastic piece 203 is restored, and then can lubricate the butterfly-shaped elastic piece 203, playing a role in reducing friction. At the same time, because the hole of the communication hole 206 is small, the flow rate of the liquid can be restricted, and then the butterfly-shaped elastic piece 203 can be prevented from bouncing suddenly and impacting the inside of the outer column 1, playing a role in shock prevention; When the movable plug 308 moves downward, the liquid in the space below the movable plug 308 in the liquid filling groove 309 will enter one of the liquid through-tubes 307 through one of the one-way liquid through mechanisms 4, and then the liquid can flow inside the mounting ring 302, so as to drive the blade 306 to rotate. After the blade 306 rotates, it can drive the inner ring 305 to rotate. After the inner ring 305 rotates, it can drive the rotating ring 303 and the outer ring 304 to rotate, and then drive the cleaning mechanism 5 to rotate. The cleaning mechanism 5 is used to scrape off the dust and impurities attached to the top column 207, preventing them from entering the inside of the accommodating groove 201 as the top column 207 moves up and down continuously for a long time, resulting in an increase in the friction between the butterfly-shaped elastic piece 203 and the inner wall of the accommodating groove 201 and causing damage to the butterfly-shaped elastic piece 203; When the movable plug 308 moves downward, it can then squeeze the liquid, causing the liquid to push one of the sealing round blocks 405 to move away from the outer column 1. When the hole 406 in the sealing round block 405 is no longer blocked by the mounting cylinder 401, the first spring 404 can be compressed, enabling the liquid to enter the interior of the mounting cylinder 401 through the hole 406 and be discharged through the liquid delivery pipe 307. When the movable plug 308 moves upward, a suction force is generated in the space below the movable plug 308 in the liquid filling groove 309. At this time, one of the sealing round blocks 405 quickly moves towards the outer column 1 under the dual action of the first spring 404 and the suction force, and then the hole 406 can be blocked by the mounting cylinder 401. At this time, the liquid cannot enter the interior of the liquid filling groove 309 from one of the mounting cylinders 401. When the movable plug 308 moves downward, the other sealing round block 405 will be pressed tightly against the inner side of the mounting cylinder 401 under the action of the liquid pressure, so that the hole 406 can be blocked by the inner side of the mounting cylinder 401. When liquid enters the other liquid delivery pipe 307, it will push the sealing round block 405 to move towards the outer column 1 under the action of the liquid pressure, enabling the other sealing round block 405 to move towards the outer column 1. Subsequently, the hole 406 in the other sealing round block 405 will no longer be blocked by the mounting cylinder 401, allowing the liquid to enter the space below the movable plug 308 in the liquid filling groove 309 from the interior of the other mounting cylinder 401, thus realizing the one-way movement of the liquid in the space composed of the two liquid delivery pipes 307 and the mounting ring 302. Subsequently, the rotating ring 303 can drive the cleaning mechanism 5 to rotate, and then the dust on the ejector pin 207 can be scraped off. When the cleaning brush 505 abuts against the outer wall of the ejector pin 207, the movable rod 504 and the limiting round block 503 are compressing the second spring 502. Therefore, the reaction force of the second spring 502 can be used to apply a force to the limiting round block 503 and the movable rod 504 towards the ejector pin 207, enabling the cleaning brush 505 to tightly abut against the outside of the ejector pin 207, and then the dust on the ejector pin 207 can be scraped off.
