Therefore, the lubricating oil can only flow along the oil delivery channel and force the rubber valve plug that has not overlapped with the connecting shaft to open, so that the lubricating oil flows out from the micropores and is distributed on the inner wall of the connecting sleeve, thereby making the connecting shaft screwed into the connecting sleeve for lubrication. At the same time, the presence of the lubricating oil also facilitates the separation of the connecting shaft and the connecting sleeve at a later stage, thereby avoiding rust on the connecting shaft and the connecting sleeve.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 3 As shown, the present invention provides a technical solution: a ball cage coupling that is easy to disassemble and assemble, comprising a ball cage body 1 and a clamping assembly 2, the clamping assembly 2 is arranged on the upper and lower sides of the ball cage body 1, the clamping assembly 2 comprises a threaded hole 201, the threaded hole 201 is opened on the upper and lower sides of the ball cage body 1, the inner cavity of the threaded hole 201 is threadedly connected with a threaded rod 202, the outer side of the threaded rod 202 is fixedly connected with an adjusting knob 203, the inner side of the threaded rod 202 is fixedly connected with a buffer plate 204, the inner side of the buffer plate 204 is fixedly connected with a clamping spring 205, and the inner side of the clamping spring 205 is fixedly connected with a clamping plate 206.

[0027] A steel ball 3 is arranged inside the ball cage body 1, a retaining frame 4 is arranged outside the steel ball 3, a star-shaped sleeve 5 is arranged inside the retaining frame 4, a connecting sleeve 10 is arranged inside the star-shaped sleeve 5, and the internal thread of the connecting sleeve 10 is connected to the connecting shaft 6. Then the staff moves the dust cover 7 to one side of the connecting shaft 6 to expose the inside of the ball cage body 1. Then the staff rotates the adjusting knob 203 to drive the threaded rod 202, and screws the threaded rod 202 out of the threaded hole 201, so that the clamping plate 206 is away from the connecting shaft 6, and the threaded layer on the outer wall of the connecting shaft 6 is matched with the threaded layer on the inner wall of the connecting sleeve 10. The staff holds the ball cage body 1 with one hand to prevent it from rotating, and holds the connecting shaft 6 with the other hand to rotate, slowly screws the connecting shaft 6 out of the inside of the ball cage body 1, and separates the connecting shaft 6 from the ball cage body 1.

[0028] like Figure 7 As shown, a dust cover 7 is sleeved on one side of the ball cage body 1, and an anti-slip assembly 8 is arranged on the outer side of the dust cover 7. The anti-slip assembly 8 includes an anti-slip ring 801, and the anti-slip ring 801 is sleeved on the outer side of the dust cover 7. A threaded hole four 802 is opened on one side of the top of the anti-slip ring 801, and the inner cavity of the threaded hole four 802 is threadedly connected with a threaded rod three 803.

[0029] One side of the threaded rod three 803 is fixedly connected with an adjusting knob three 804, and the other side of the top of the anti-slip ring 801 is provided with a threaded hole five 805. The interior of the ball cage body 1 is provided with a lubrication component 9. When the device needs to be disassembled, the staff can first rotate the adjusting knob three 804. While rotating the adjusting knob three 804, the threaded rod three 803 is driven to rotate from the inside of the threaded hole four 802 and the threaded hole five 805, and the threaded rod three 803 is screwed out from the inside of the threaded hole four 802 and the threaded hole five 805, so that the connection between the ball cage body 1 and the dust cover 7 becomes loose.

[0030] like Figure 6 As shown, the lubrication assembly 9 includes a miniature oil box 901, which is fixedly connected to both sides of the inside of the ball cage body 1, one side of the miniature oil box 901 is fixedly connected to an oil supply hose 902, and the top of the miniature oil box 901 is fixedly connected to an extrusion spring 903, the lubrication assembly 9 also includes a connecting branch pipe 904, the other side of the miniature oil box 901 is connected to a connecting branch pipe 904, and the connecting branch pipe 904 is connected to the guide tube 16, the lubrication assembly 9 also includes a flexible rod 905, a sealing plate 906 and an oil hole 907, the inside of the extrusion spring 903 is provided with a flexible rod 905, and the bottom of the flexible rod 905 is fixed with a sealing plate 906, and the surface of the sealing plate 906 is provided with an oil hole 907;

[0031] Specifically, when the lubricating oil is injected into the dust cover 7, part of the lubricating oil will be injected into the micro oil box 901 along the conduit 16 and the connecting branch pipe 904. The lubricating oil is blocked by the sealing plate 906 inside the micro oil box 901 and stored on one side of the micro oil box 901. When the angle between the ball cage body 1 and the connecting shaft 6 changes, the extrusion spring 903 on one side is squeezed. At this time, the extrusion spring 903 contracts and carries the flexible rod 905 downward, causing the sealing plate 906 to descend inside the micro oil box 901, so that the height of the oil hole 907 is reduced and descends to the inside of the micro oil box 901. At this time, the lubricating oil is able to pass through the oil hole 907 and flow out from the oil supply hose 902, and the lubricating oil inside the micro oil box 901 is injected into the inner wall of the ball cage body 1 and the steel ball 3 through the oil supply hose 902, thereby reducing the rolling resistance of the steel ball 3. The end of the oil supply hose 902 has a smaller diameter, so that the lubricating oil flows out slowly to avoid waste.

[0032] like Figure 4-5 As shown, an oil delivery channel 11 is opened in the inner wall of the connecting sleeve 10, and micropores connected to the oil delivery channel 11 are evenly opened on the inner surface of the connecting sleeve 10, and a rubber flap plug 12 is arranged inside the micropores. A transmission spring 13 is arranged inside the connecting sleeve 10, and a series oil bag 14 is arranged inside the transmission spring 13. The series oil bag 14 is connected to the oil delivery channel 11, and the ends of the series oil bag 14 and the transmission spring 13 are connected to a pressing plate 15. The outer end is connected with a catheter 16, a dust cover 7 is sleeved on one side of the cage body 1, an injection hole 17 is opened on the surface of the dust cover 7, and a rubber plug is arranged inside the injection hole 17, the dust cover 7 is a cavity structure, and lubricating oil is injected into the structure of the dust cover 7, magnets 18 are arranged on both sides of the cavity structure, and an elastic rope 19 is arranged between the magnets 18, and a plug 20 is arranged at the bottom of one end of the dust cover 7 close to the cage body 1, and the plug 20 is plug-connected with the catheter 16;

[0033] Specifically, the dust cover 7 is sleeved with the cage body 1 and reinforced or secured with the anti-slip assembly 8, the insert tube 20 is plugged and connected with the end of the conduit 16, at which time the dust cover 7 is in a contracted structure, and the two sides of the interior thereof are shrunk due to the mutual adsorption and adhesion of the magnets 18, and then the pump body and the tube body with a structure similar to an injection needle are used to penetrate the rubber plug and inject lubricating oil into the cavity structure of the cage body 1, and as the lubricating oil is injected, the dust cover 7 is stretched, and at this time, the magnets 18 are moved away from each other due to the injection of the lubricating oil, until the lubricating oil fills the cavity structure and then fills the conduit 16 and the inside of the oil delivery channel 11;

[0034] When the connecting shaft 6 is twisted to separate it from the connecting sleeve 10, the serial oil bag 14 and the transmission spring 13 are reset, thereby extracting the lubricating oil in the dust cover 7 and replenishing it into the serial oil bag 14. At this time, the lubricating oil level in the dust cover 7 drops. At the same time, due to the drop in the lubricating oil level, the elastic rope 19 contracts, so that the magnets 18 are close to each other. The dust cover 7 contracts by the adsorption effect between the magnets 18, so that the lubricating oil inside it is squeezed and replenished into the serial oil bag 14, thereby preparing for the next threaded connection between the connecting shaft 6 and the connecting sleeve 10;

[0035] When the connecting shaft 6 is screwed into the connecting sleeve 10, the lubricating oil is squeezed out from the inside of the series oil bag 14 by the pushing action, wherein the force generated by the squeezing of the series oil bag 14 is smaller than the adsorption force between the magnets 18, so that the lubricating oil cannot enter the inside of the dust cover 7 to stretch it, so the lubricating oil can only flow along the inside of the oil delivery channel 11 and force the rubber flap plug 12 that has not overlapped with the connecting shaft 6 to be forced to open, so that the lubricating oil flows out from the micropores and is distributed on the inner wall of the connecting sleeve 10, thereby making the connecting shaft 6 screwed into the connecting sleeve 10 for lubrication, and the presence of the lubricating oil also facilitates the subsequent separation of the connecting shaft 6 and the connecting sleeve 10, thereby avoiding the rusting of the connecting shaft 6 and the connecting sleeve 10;

[0036] The use method and advantages of the present invention: When the ball cage coupling is easy to disassemble and assemble, the working process is as follows:

[0037] like Figure 1-Figure 7As shown, when the device needs to be disassembled, the staff can first rotate the adjusting knob three 804. When the adjusting knob three 804 is rotated, the threaded rod three 803 is driven to rotate from the inside of the threaded hole four 802 and the threaded hole five 805, and the threaded rod three 803 is screwed out from the inside of the threaded hole four 802 and the threaded hole five 805, so that the connection between the ball cage body 1 and the dust cover 7 becomes loose. Then the staff moves the dust cover 7 to one side of the connecting shaft 6, so that the inside of the ball cage body 1 is exposed. Then the staff rotates the adjusting knob one 203 to drive the threaded rod one 202, and screws the threaded rod one 202 out of the inside of the threaded hole one 201, so that the clamping plate 206 is away from the connecting shaft 6, and the threaded layer on the outer wall of the connecting shaft 6 is matched with the threaded layer on the inner wall of the star sleeve 5. The staff holds the ball cage body 1 with one hand to prevent it from rotating, and holds the connecting shaft 6 with the other hand to rotate, and slowly screws the connecting shaft 6 out of the inside of the ball cage body 1. Separate the connecting shaft 6 from the ball cage body 1. At this time, the ball cage body 1 is removed for inspection. Otherwise, it can be installed. When the pressing spring 205 and the pressing plate 206 are pressed, the pressing spring 205 is in a semi-contracted state and can bear pressure without affecting the transmission. When the angle between the ball cage body 1 and the connecting shaft 6 changes, the squeezing spring 903 on one side is squeezed. At this time, the squeezing spring 903 contracts and carries the flexible rod 905 downward, so that the sealing plate 906 is lowered inside the micro oil box 901, so that the height of the oil hole 907 is reduced and dropped into the micro oil box 901. At this time, the lubricating oil can pass through the oil hole 907 and flow out from the oil supply hose 902, and the lubricating oil inside the micro oil box 901 is injected into the inner wall of the ball cage body 1 and the steel ball 3 through the oil supply hose 902, reducing the rolling resistance of the steel ball 3. The end of the oil supply hose 902 has a smaller diameter, so that the lubricating oil flows out slowly to avoid waste.

[0038] The dust cover 7 is sleeved with the cage body 1 and reinforced or secured with the anti-slip assembly 8. The cannula 20 is plugged and connected with the end of the conduit 16. At this time, the dust cover 7 is in a contracted structure, and the two sides inside it are shrunk due to the mutual adsorption and adhesion of the magnets 18. Then, the pump body and the tube body with a structure similar to an injection needle are used to penetrate the rubber plug and inject lubricating oil into the cavity structure of the cage body 1. As the lubricating oil is injected, the dust cover 7 is stretched. At this time, the magnets 18 are moved away from each other due to the injection of the lubricating oil, until the lubricating oil fills the cavity structure and then fills the conduit 16 and the oil delivery channel 11.

[0039] When the connecting shaft 6 is twisted to separate it from the connecting sleeve 10, the serial oil bag 14 and the transmission spring 13 are reset, thereby extracting the lubricating oil in the dust cover 7 and replenishing it into the serial oil bag 14. At this time, the lubricating oil level in the dust cover 7 drops. At the same time, due to the drop in the lubricating oil level, the elastic rope 19 contracts, so that the magnets 18 are close to each other. The dust cover 7 contracts by the adsorption effect between the magnets 18, so that the lubricating oil inside it is squeezed and replenished into the serial oil bag 14, thereby preparing for the next threaded connection between the connecting shaft 6 and the connecting sleeve 10;

[0040] When the connecting shaft 6 is screwed into the connecting sleeve 10, the lubricating oil is squeezed out from the inside of the series oil bag 14 by the pushing action, wherein the force generated by the squeezing of the series oil bag 14 is smaller than the adsorption force between the magnets 18, so that the lubricating oil cannot enter the inside of the dust cover 7 to stretch it. Therefore, the lubricating oil can only flow along the inside of the oil delivery channel 11 and force the rubber valve plug 12 that has not overlapped with the connecting shaft 6 to be forced to open, so that the lubricating oil flows out from the micropores and is distributed on the inner wall of the connecting sleeve 10, thereby making the connecting shaft 6 screwed into the connecting sleeve 10 for lubrication. At the same time, the presence of the lubricating oil also facilitates the subsequent separation of the connecting shaft 6 and the connecting sleeve 10, thereby avoiding rust on the connecting shaft 6 and the connecting sleeve 10.
