[0034] The following specifically describes the specific settings and functions of its lubrication device 4
[0035] As Figures 2-8As shown, the lubrication device 4 includes a connection frame 401. The connection frame 401 is fixedly connected to the shaft body 2. An oil injection pipe 402 communicates with the surface of the connection frame 401. A plurality of oil outlet grooves 403 are formed on the surface of the connection frame 401. All the plurality of oil outlet grooves 403 communicate with the arc surface of the shaft body 2. A screw cylinder 404 is fixedly connected to the surface of the connection frame 401. A lead screw 405 is threadedly connected to the inner wall of the screw cylinder 404. A sponge plate 406 is slidably connected to the arc surface of the lead screw 405. The sponge plate 406 is slidably connected to the outer wall of the screw cylinder 404. A sealing shell 407 is threadedly connected to the arc surface of the lead screw 405. The sealing shell 407 matches the size of the connection frame 401. A connection ring 408 is fixedly connected to the surface of the oil outlet groove 403. A ball 409 is rotatably connected to the surface of the connection ring 408. The shaft body 2 drives the ball 409 on the connection ring 408 to roll. At this time, the connection ring 408 and the ball 409 can make the lubricating oil enter the oil injection groove evenly. An oil absorption rope 410 is fixedly connected to the surface of the connection ring 408. The oil absorption rope 410 is a cotton rope. When the lubricating oil enters the oil injection groove, it will be absorbed by the oil absorption rope 410. At this time, the oil absorption rope 410 made of cotton can make the lubricating oil evenly adhere to the arc surface of the shaft body 2. Two limiting frames 411 are fixedly connected to the surface of the connection frame 401. A sliding rod 412 is slidably connected to the surface of each of the two limiting frames 411. A spring 413 is sleeved on the arc surface of the sliding rod 412. Both ends of the spring 413 are fixedly connected to the sliding rod 412 and the limiting frame 411 respectively. Two limiting plates 414 are fixedly connected to the surface of the sealing shell 407. A clamping groove 415 is formed on the surface of each of the two limiting plates 414. The limiting plate 414 matches the size of the limiting frame 411. The limiting plate 414 on the sealing shell 407 is inserted into the limiting frame 411. At this time, the limiting plate 414 will drive the first inclined plate 416 into the limiting frame 411. Then the first inclined plate 416 will abut against the second inclined plate 417. Then the second inclined plate 417 will be squeezed by the first inclined plate 416 to press the sliding rod 412. At this time, the sliding rod 412 will move away from the limiting frame 411. Then the sliding rod 412 will drive one end of the spring 413 to move. At this time, the spring 413 itself will generate a retracting pulling force. Then when the first inclined plate 416 is separated from the second inclined plate 417 and the limiting plate 414 drives the clamping groove 415 to reach the position of the second inclined plate 417, the spring 413 will drive the sliding rod 412 to move towards the limiting frame 411 under the action of its own pulling force. At this time, the sliding rod 412 will drive the second inclined plate 417 to be clamped with the clamping groove 415. Through the cooperation among the limiting frame 411, the sliding rod 412, the spring 413, the limiting plate 414 and the clamping groove 415, the sealing shell 407 and the connection frame 401 can be temporarily limited. A first inclined plate 416 is fixedly connected to the surface of the limiting plate 414. A second inclined plate 417 is fixedly connected to one end of the sliding rod 412. The second inclined plate 417 is slidably connected to the first inclined plate 416. The limiting plate 414 will drive the first inclined plate 416 into the limiting frame 411,Next, the first inclined plate 416 will abut against the second inclined plate 417, and then the second inclined plate 417 will squeeze the sliding rod 412 under the action of the first inclined plate 416. By using the first connecting plate and the second connecting plate, the mutual sliding effect between the two inclined surfaces of the first inclined plate 416 and the second inclined plate 417 can be utilized to realize the direct pressing and clamping of the limiting frame 411 and the limiting rod. A sealing ring 418 is fixedly connected to the surface of the sealing shell 407. The sealing ring 418 is a rubber ring. The sealing shell 407 will drive the sealing ring 418 to be clamped with the connecting frame 401. At this time, the sealing ring 418 made of rubber can increase the sealing performance between the sealing shell 407 and the connecting frame 401. One end of the lead screw 405 is fixedly connected with a sharp cone 419. The sharp cone 419 is a stainless steel cone. The lead screw 405 will drive the sharp cone 419 to move towards the inner wall of the screw barrel 404. At this time, the sharp cone 419 can facilitate the lead screw 405 to enter the screw barrel 404.,
[0036] The overall working principle is as follows. When it is necessary to lubricate the shaft body 2, first put the sponge block on the screw barrel 404, and then insert the limiting plate 414 on the sealing shell 407 into the limiting frame 411. At this time, the limiting plate 414 will drive the first inclined plate 416 into the limiting frame 411. Then the first inclined plate 416 will abut against the second inclined plate 417. Then the second inclined plate 417 will squeeze the sliding rod 412 under the action of the first inclined plate 416. At this time, the sliding rod 412 will move away from the limiting frame 411. Then the sliding rod 412 will drive one end of the spring 413 to move. At this time, the spring 413 itself will generate a retracting pulling force. Then when the first inclined plate 416 is separated from the second inclined plate 417, and the limiting plate 414 drives the clamping groove 415 to reach the position of the second inclined plate 417, the spring 413 will drive the sliding rod 412 to move towards the limiting frame 411 under the action of its own pulling force. At this time, the sliding rod 412 will drive the second inclined plate 417 to be clamped with the clamping groove 415. Through the cooperation between the limiting frame 411, the sliding rod 412, the spring 413, the limiting plate 414 and the clamping groove 415, the sealing shell 407 and the connecting frame 401 can be temporarily limited. At this time, by using the first connecting plate and the second connecting plate, the direct pressing and clamping can be realized by means of the mutual sliding effect between the two inclined surfaces of the first inclined plate 416 and the second inclined plate 417. Then rotate the screw rod 405 to threadedly connect and fix the screw rod 405 with the sealing shell 407 and the screw barrel 404. At the same time, the screw rod 405 will drive the sharp cone 419 to move towards the inner wall of the screw barrel 404. At this time, the sharp cone 419 can facilitate the entry of the screw rod 405 into the screw barrel 404. At the same time, the sealing shell 407 will drive the sealing ring 418 to be clamped with the connecting frame 401. At this time, the sealing ring 418 made of rubber material can increase the sealing performance between the sealing shell 407 and the connecting frame 401. Then when the screw rod 405 is fixed with the screw barrel 404, lubricating oil can be injected from the oil injection pipe 402 at this time. Then the lubricating oil will enter the sponge plate 406. Then rotate the first connecting piece 1 and the second connecting piece to drive the shaft body 2 to rotate. At this time, the sponge plate 406 will apply the lubricating oil on the balls 409. At the same time, the shaft body 2 will drive the balls 409 on the connecting ring 408 to roll. At this time, the connecting ring 408 and the balls 409 can make the lubricating oil evenly enter the oil injection groove. Then when the lubricating oil enters the oil injection groove, it will be absorbed by the oil absorbing rope 410. At this time, the oil absorbing rope 410 made of cotton material can make the lubricating oil evenly adhere to the arc surface of the shaft body 2. By setting the lubricating device 4, through the mutual cooperation between the connecting frame 401, the oil injection pipe 402, the oil outlet groove 403, the screw barrel 404, the screw rod 405, the sponge plate 406 and the sealing shell 407, when lubricating the shaft body 2, the lubricating oil can evenly reach the arc surface of the shaft body 2, avoiding the corrosion of the shaft body 2 due to the influence of environmental factors after long-term use of the shaft body 2. When lubricating oil is injected into the shaft body 2, the situation that the lubricating oil drips on the placement surface occurs, resulting in uneven lubricating oil on the surface of the shaft body 2.Improved the uniformity of the lubricating oil on the surface of the shaft body 2 and reduced the waste of the lubricating oil.
