The inside of the oil storage tank 5 is movably provided with a first blocking block 11 and a second blocking block 12 at the oil outlet pipe 9 and the air intake pipe 8, respectively. The top outer surface of the first blocking block 11 is fixedly connected with an arc plate 10, and the bottom outer surface of the arc plate 10 is fixedly connected with a pull rope 13, and the other end of the pull rope 13 is connected with the second The blocking block 12 is fixedly connected, the top outer surface of the arc plate 10 is fixedly connected with a fixing cylinder 16, the interior of the fixing cylinder 16 is fixedly connected with a fixing disk, the outer surface of the fixing disk is threaded with a threaded rod 17, the bottom inner surface of the oil storage tank 5 is fixedly connected with a return spring, and the other end of the return spring is fixedly connected to the bottom outer surface of the arc plate 10. Specifically, the threaded rod 17 is rotated to make the extrusion steel ball 18 move upward, so that the limit steel ball 19 is released from the limit, so that the limit steel balls 19 are retracted, so that the fixed cylinder 16 and the connecting cylinder 20 are contacted and limited, and the arc plate 10 moves upward under the action of the return spring. When the arc plate 10 moves upward, it drives the pull rope 13 to move upward. The pull rope 13 pulls the second block 12 to detach from the air inlet pipe 8, so that the first block 11 and the second block 12 are detached from the oil outlet pipe 9 and the air inlet pipe 8 respectively. As the inner ring 2 rotates, the pulley 31 is driven to slide on the surface of the inflation tube 7 and squeeze the inflation tube 7. As the pulley 31 squeezes the inflation tube 7, the outside gas enters the inflation tube 7 to inflate it, so that as the pulley 31 slides, the pressure inside the oil storage tank 5 increases, and then the lubricating oil enters the oil filling pipe 6 from the oil outlet pipe 9, and enters the ball 3 through the small hole for lubrication.

When the limiting steel ball 19 is retracted, the elastic member 27 is reset and drives the connecting plate to reset the limiting steel ball 19.

[0034] In this embodiment, an oil filling hole is provided on the top outer surface of the oil storage tank 5, and the other end of the oil filling hole extends to the outside of the outer ring 1. The internal thread of the oil filling hole is connected to a sealing head 30, and a plum blossom groove is provided on the outer surface of the sealing head 30. Specifically, the sealing head 30 is unscrewed by a plum blossom rod, and lubricating oil is added to the oil storage tank 5 through the oil filling hole.

[0035] In this embodiment, the interior of the inflation tube 7 is fixedly connected to a balancing tube, the other end of the balancing tube extends to the outside of the outer ring 1, and a one-way valve is installed inside the balancing tube. The conduction direction of the one-way valve is from the outside of the balancing tube to the inside of the balancing tube. Specifically, when the balancing tube is squeezed, outside air enters the inflation tube 7 through the balancing tube, so that the inflation tube 7 is re-inflated and reset after being squeezed.

[0036] In this embodiment, an L-shaped plate 15 is fixedly connected to the outer surface of the second blocking block 12, and a cross bar is fixedly connected to the inside of the oil storage tank 5. The L-shaped plate 15 is movably sleeved on the outer surface of the cross bar. A first spring 14 is fixedly connected between the L-shaped plate 15 and the inner wall of the oil storage tank 5. The first spring 14 is sleeved on the outer surface of the cross bar. Specifically, when the arc plate 10 moves downward, the first spring 14 drives the second blocking block 12 to reset, so that the second blocking block 12 closes the intake pipe 8.

[0037] In this embodiment, two guide wheels are installed inside the oil storage tank 5, and the pull rope 13 passes around the outer surfaces of the two guide wheels respectively. Specifically, the pull rope 13 passes around the guide wheels, and the guide wheels guide the pull rope 13, so that when the arc plate 10 moves upward, it can drive the pull rope 13 to pull the second blocking block 12, so that the second blocking block 12 is detached from the intake pipe 8.

[0038] In this embodiment, the first blocking block 11 and the second blocking block 12 are both conical blocks, and the outer surfaces of the first blocking block 11 and the second blocking block 12 are fixedly connected with sealing gaskets. Specifically, the conical blocks are used to facilitate blocking the air intake pipe 8 and the oil outlet pipe 9, and the sealing gaskets are used to increase the sealing performance between each blocking block and the air intake pipe 8 and the oil outlet pipe 9.

[0039] During the specific implementation process, when oil injection and lubrication are not required, the inflation pipe 7 and the air intake pipe 8 are both in a blocked state. When the inner ring 2 rotates, the inside of the inflation pipe 7 remains in a normal state. When lubricating oil needs to be injected, the threaded rod 17 is rotated to make the extruded steel ball 18 move upward, so that the limit steel ball 19 is released from the limit, so that the limit steel balls 19 are retracted, so that the fixed cylinder 16 and the connecting cylinder 20 are contacted and limited, and the arc plate 10 moves upward under the action of the reset spring. When the arc plate 10 moves upward, it drives the pull rope 13 to move upward, and the pull rope 13 pulls the second block 12 to detach from the air intake pipe 8, so that the first block 11 and the second block 12 are respectively separated from the oil outlet pipe 9 and the air intake pipe 8 is disengaged, and as the inner ring 2 rotates, the pulley 31 is driven to slide on the surface of the inflation tube 7 and squeeze the inflation tube 7. As the pulley 31 squeezes the inflation tube 7, external gas enters the inflation tube 7 to inflate it, so that as the pulley 31 slides, the pressure inside the oil storage tank 5 increases, and then the lubricating oil enters the oil filling pipe 6 from the oil outlet pipe 9 and enters the ball 3 through the small hole for lubrication, so that the air pressure generated when the inner ring 2 rotates can be used for lubrication, which improves the uniformity and lubrication effect of lubrication. When no oil injection is needed, the threaded rod 17 is rotated in the opposite direction, so that the first spring 14 drives the second block 12 to reset, so that the first block 11 and the second block 12 respectively block the oil outlet pipe 9 and the air inlet pipe 8.

[0040] Embodiment 2:

[0041] Please refer to Figure 1-Figure 9 The present invention provides a technical solution: the top outer surface of the outer ring 1 and the top outer surface of the oil storage tank 5 are both provided with through holes, the through hole is located inside the oil storage tank 5 and is movably connected with a third block 22, the through hole is located outside the outer ring 1 and is fixedly connected with a connecting ring 26, the top outer surface of the third block 22 is fixedly connected with a second spring 25, the other end of the second spring 25 is fixedly connected to the bottom outer surface of the connecting ring 26, the top outer surface of the third block 22 is fixedly connected with a rotating head 24, the outer surface of the third block 22 is rotatably penetrated by a rotating drum 23, the bottom outer surface of the rotating drum 23 is fixedly connected with a polygonal block, and the top outer surfaces of the rotating head 24 and the connecting head 21 are both provided with polygonal grooves adapted to the polygonal blocks.

[0042] In this embodiment, the third blocking blocks 22 are all conical blocks, and the outer surfaces of the third blocking blocks 22 are fixedly connected with sealing gaskets, which facilitate the blocking of the through holes through the conical blocks, and increase the sealing performance between each third blocking block 22 and the through holes through the sealing gaskets.

[0043] In the specific implementation process, when adjusting the threaded rod 17, a polygonal rod corresponding to the polygonal groove is inserted into the polygonal groove of the rotating head 24, and force is applied downward so that the polygonal block at the bottom of the rotating drum 23 is inserted into the polygonal groove of the connecting head 21. At this time, the third blocking block 22 moves downward to connect the through hole, and then the polygonal rod is rotated to rotate the rotating drum 23, and the rotating drum 23 drives the threaded rod 17 to rotate. After the adjustment is completed, the second spring 25 is reset to drive the third blocking block 22 to close the through hole to prevent the lubricating oil from being thrown out of the through hole under the action of centrifugal force.

[0044] Embodiment 3:

[0045] Please refer to Figure 1-Figure 9 The present invention provides a technical solution: the outer surface of the outer ring 1 is fixedly connected with an elastic cloth, the outer periphery of the elastic cloth is provided with a sealing ring 28, the other end of the sealing ring 28 is movably fitted with the outer part of the inner ring 2, an airbag tube 29 is provided inside the elastic cloth, the outer surface of the airbag tube 29 is fixedly connected with an air injection tube, and the air injection tube runs through the elastic cloth. Specifically, the sealing performance between the inner ring 2 and the top of the outer ring 1 is increased by the sealing ring 28 to avoid the lubricating oil being thrown out when the centrifugal force is too large when the bearing rotates, and gas is injected into the air injection tube to expand the airbag tube 29, so that the other end of the sealing ring 28 is closely attached to the outer wall of the inner ring 2, so that the sealing performance of the sealing ring 28 after long-term use can be adjusted.

[0046] In the specific implementation process, the sealing between the inner ring 2 and the top of the outer ring 1 is increased by the sealing ring 28 to prevent the lubricating oil from being thrown out when the centrifugal force is too large when the bearing rotates, thereby affecting the use of the dental mobile phone. After long-term use, the sealing ring 28 will be worn and the sealing performance will be reduced. At this time, gas is injected into the air injection tube to expand the air bag tube 29, so that the other end of the sealing ring 28 is close to the outer wall of the inner ring 2, so that the sealing performance of the sealing ring 28 after long-term use can be adjusted.

[0047] Working principle: When the present invention is in use, when oil injection and lubrication are not required, the inflation pipe 7 and the air inlet pipe 8 are both in a blocked state, and when the inner ring 2 rotates, the inside of the inflation pipe 7 remains in a normal state. When lubricating oil needs to be injected, the threaded rod 17 is rotated to make the extrusion steel ball 18 move upward, so that the limit steel ball 19 is released from the limit, so that the limit steel ball 19 is retracted, so that the fixed cylinder 16 and the connecting cylinder 20 are contacted and limited, and the arc plate 10 is moved upward under the action of the reset spring. When the arc plate 10 moves upward, it drives the pull rope 13 to move upward, and the pull rope 13 pulls the second block 12 to detach from the air inlet pipe 8, so that the first block 11 and the second block 12 are respectively released from the oil outlet pipe 9 and the air inlet pipe 8. The air pipe 8 is detached, and as the inner ring 2 rotates, the pulley 31 is driven to slide on the surface of the inflation pipe 7 and squeeze the inflation pipe 7. As the pulley 31 squeezes the inflation pipe 7, external gas enters the inflation pipe 7 to inflate it, so that as the pulley 31 slides, the pressure inside the oil storage tank 5 increases, and then the lubricating oil enters the oil filling pipe 6 from the oil outlet pipe 9 and enters the ball 3 through the small hole for lubrication, so that the air pressure generated when the inner ring 2 rotates can be used for lubrication, which improves the uniformity and lubrication effect of lubrication. When no oil injection is needed, the threaded rod 17 is rotated in the opposite direction, so that the first spring 14 drives the second block 12 to reset, so that the first block 11 and the second block 12 respectively block the oil outlet pipe 9 and the air inlet pipe 8.

[0048] When adjusting the threaded rod 17, a polygonal rod corresponding to the polygonal groove is inserted into the polygonal groove of the rotating head 24, and force is applied downward so that the polygonal block at the bottom of the rotating drum 23 is inserted into the polygonal groove of the connecting head 21. At this time, the third blocking block 22 moves downward to connect the through hole, and then the rotating polygonal rod is rotated to rotate the rotating drum 23, which drives the threaded rod 17 to rotate. After the adjustment is completed, the second spring 25 is reset to drive the third blocking block 22 to close the through hole to prevent the lubricating oil from being thrown out of the through hole under the action of centrifugal force.

[0049] The sealing ring 28 is used to increase the sealing between the inner ring 2 and the top of the outer ring 1 to prevent the lubricating oil from being thrown out when the centrifugal force is too large when the bearing rotates, thereby affecting the use of the dental mobile phone. After long-term use, the sealing ring 28 will be worn and the sealing performance will be reduced. At this time, gas is injected into the air injection tube to expand the air bag tube 29, so that the other end of the sealing ring 28 is close to the outer wall of the inner ring 2, so that the sealing performance of the sealing ring 28 after long-term use can be adjusted.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
