DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 3As shown, a multi-output spherical joint for a polarized light therapy device described in an embodiment of the present invention includes a first connecting rod 1; a collar 12 is fixedly connected to the end of the first connecting rod 1; a ball 13 is rotatably connected to the middle of the collar 12; a pair of second connecting rods 14 are symmetrically arranged and fixed to the middle of the ball 13; a plurality of first sliding grooves 15 are opened in the middle of the inner side of the collar 12 in pairs; a slide plate 16 is slidably connected to the middle of the first sliding groove 15; a spring 17 is fixed to the side of the slide plate 16 facing the ball 13; the other end of the spring 17 is fixed to a top column 18; when working, the ends of the plurality of top columns 18 will continue to rotate under the elastic force of the spring 17 The surface of the ball 13 is squeezed so that the ball 13 is in the center of the ring 12 as much as possible, reducing the contact between the ball 13 and the ring 12. When the angle of a pair of second connecting rods 14 is adjusted by rotating the ball 13, the friction between the ball 13 and the ring 12 is reduced. After long-term use, the ball 13 will wear and become smaller. At this time, due to the squeezing of the ball 13 by multiple top columns 18, the ball 13 will not easily fall off from the inside of the ring 12. Through the above structure, the wear and tear of the ball 13 during use can be reduced. At the same time, after the ball 13 becomes smaller due to wear, it will not easily fall off from the inside of the ring 12, thereby reducing the occurrence of the therapeutic device bracket falling off.
[0024] like Figures 1 to 4 As shown, a hollow groove 2 is provided in the middle of the inner wall of the collar 12; a cotton pad 21 is fixedly connected to the middle of the hollow groove 2; a cotton belt 22 is fixedly connected to the side of the cotton pad 21 facing the ball 13; the cotton belt 22 extends out of the interior of the hollow groove 2; a liquid injection tube 23 is fixedly connected to the middle of the outer side of the collar 12; the liquid injection tube 23 is communicated with the hollow groove 2; a threaded plug 24 is threadedly connected to the middle of the liquid injection tube 23; when working, lubricating liquid can be injected into the interior of the hollow groove 2 through the liquid injection tube 23, and the lubricating liquid inside the hollow groove 2 will soak into the interior of the cotton pad 21 and soak the cotton belt 22 at the same time, completing the operation. After the lubricating liquid is filled, the threaded plug 24 is rotated into the middle of the liquid injection tube 23 to prevent the lubricating liquid from flowing out. When the ball 13 rotates, the cotton belt 22 will contact and rub against the surface of the ball 13, so that the lubricating liquid inside the cotton belt 22 adheres to the surface of the ball 13, so that the friction between the ball 13 and the top column 18 or the ring 12 is reduced. Through the above structure, the surface of the ball 13 can be lubricated, the friction between the ball 13 and other components can be reduced, and the wear of the ball 13 can be reduced, which can further reduce the occurrence of the therapeutic device bracket falling off.
[0025] like Figures 1 to 5As shown, a rubber ring 3 is fixedly connected to the middle part of the inner side of the liquid injection tube 23; the rubber ring 3 is annular; a cylindrical head 31 is fixedly connected to the end of the threaded plug 24 facing the cotton pad 21; the diameter of the cylindrical head 31 is slightly larger than the inner ring diameter of the rubber ring 3; during operation, after the filling of the lubricating liquid is completed, the threaded plug 24 is screwed into the interior of the liquid injection tube 23. As the threaded plug 24 rotates and moves, the cylindrical head 31 will squeeze into the interior of the rubber ring 3, so that the rubber ring 3 completely blocks the gap between the cylindrical head 31 and the liquid injection tube 23, so that the lubricating liquid will not flow out. Through the above structure, the lubricating liquid can be effectively prevented from flowing out of the gap between the liquid injection tube 23 and the threaded plug 24, thereby preventing the lubricating liquid from convecting to the outer wall of the collar 12, and causing dust to adhere to the outer wall of the collar 12.
[0026] like Figures 1 to 3 As shown, a thread groove 4 is formed at one end of the first chute 15 away from the ball 13; the thread groove 4 is set through the collar 12, and the diameter of the thread groove 4 is smaller than the diameter of the first chute 15; a bolt 41 is threadedly connected to the middle part of the thread groove 4; the length of the bolt 41 is greater than the length of the thread groove 4; during operation, after long-term use, multiple top columns 18 will wear out due to friction with the ball 13, thereby shortening the length of the top column 18. When the top column 18 shortens, the spring 17 will extend accordingly, thereby causing the spring 17 to extend. The elastic force of 17 is reduced, thereby causing the squeezing force of the multiple top columns 18 on the ball 13 to be reduced. At this time, the bolt 41 can be moved toward the ball 13 by rotating the bolt 41, so that the bolt 41 squeezes the slide plate 16, thereby compressing the spring 17, and thereby increasing the squeezing force of the multiple top columns 18 on the ball 13. Through the above structure, the squeezing force of the multiple top columns 18 on the ball 13 can be adjusted, and after the multiple top columns 18 are worn, the ball 13 can be reduced from falling off from the inside of the ring 12 by adjusting the bolt 41.
[0027] like Figures 1 to 3 As shown, a through groove 5 is provided in the middle of the bolt 41; a pull rope 51 is fixedly connected to the end of the top column 18 facing the bolt 41; a pull block 52 is fixedly connected to the end of the pull rope 51; during operation, after the ball 13 is worn to a certain extent, the ball 13 can be removed from the middle of the ring 12, and then a new ball 13 can be replaced. At this time, the multiple top columns 18 can be moved in the opposite direction away from the ball 13 by pulling the pull block 52, so that the obstruction of the multiple top columns 18 to the ball 13 during the installation process of the ball 13 is reduced. Through the above structure, the obstruction of the multiple top columns 18 to the ball 13 can be reduced when the ball 13 is replaced.
[0028] like Figures 1 to 5As shown, a second slide groove 6 is opened in the middle of the ring 12; the second slide groove 6 is connected to the empty slot 2; a slide column 61 is slidably connected to the middle of the second slide groove 6; one end of the slide column 61 is fixedly connected to a pressure plate 62; the pressure plate 62 is located inside the empty slot 2; during operation, after the lubricating liquid inside the cotton belt 22 is consumed, the lubricating liquid inside it is difficult to flow directly to the surface of the ball 13. At this time, the slide column 61 can be pressed to drive the pressure plate 62 to squeeze the cotton pad 21, and then the residual lubricating liquid inside the cotton pad 21 can be squeezed onto the surface of the ball 13. Through the above structure, the utilization rate of the lubricating liquid inside the cotton pad 21 can be increased.
[0029] like Figures 1 to 5 As shown, a pair of dustproof pads 7 are fixed to the inner side of the collar 12; the pair of dustproof pads 7 are symmetrically arranged; when working, the pair of dustproof pads 7 will continuously contact the surface of the ball 13, thereby preventing external impurities from entering between the ball 13 and the collar 12 to cause blockage, thereby preventing the ball 13 from being subjected to greater wear due to the blocked debris.
[0030] During operation, the ends of the multiple top columns 18 will continuously squeeze the surface of the ball 13 under the elastic force of the spring 17, so that the ball 13 is as close to the center of the collar 12 as possible, reducing the contact between the ball 13 and the collar 12. When the angle of the pair of second connecting rods 14 is adjusted by rotating the ball 13, the friction between the ball 13 and the collar 12 is reduced. After long-term use, the ball 13 will wear and become smaller. At this time, due to the squeezing of the ball 13 by the multiple top columns 18, the ball 13 will not easily fall off from the inside of the collar 12. Lubricating liquid can be injected into the inside of the empty groove 2 through the injection pipe 23. At this time, the empty groove 2 The internal lubricating liquid will soak into the inside of the cotton pad 21 and soak the cotton belt 22 at the same time. After the lubricating liquid is filled, the threaded plug 24 is rotated into the middle of the liquid injection tube 23 to prevent the lubricating liquid from flowing out. When the ball 13 rotates, the cotton belt 22 will contact and rub against the surface of the ball 13, thereby causing the lubricating liquid inside the cotton belt 22 to adhere to the surface of the ball 13, reducing the friction when the ball 13 rubs against the top column 18 or the collar 12. After the lubricating liquid is filled, the threaded plug 24 is screwed into the inside of the liquid injection tube 23. As the threaded plug 24 rotates and moves, the cylindrical head 31 will squeeze into the inside of the rubber ring 3. The rubber ring 3 completely blocks the gap between the cylindrical head 31 and the injection tube 23 to prevent the lubricant from flowing out. After long-term use, the multiple top columns 18 will wear out due to the friction between them and the ball 13, thereby shortening the length of the top column 18. When the top column 18 shortens, the spring 17 will extend, thereby reducing the elastic force of the spring 17, thereby reducing the squeezing force of the multiple top columns 18 on the ball 13. At this time, the bolt 41 can be moved toward the ball 13 by rotating the bolt 41, so that the bolt 41 squeezes the slide plate 16, thereby compressing the spring 17, and then the multiple top columns 18 on the ball 13. The extrusion force increases. After the ball 13 is worn to a certain extent, the ball 13 can be removed from the middle of the ring 12 and then replaced with a new ball 13. At this time, the pull block 52 can be pulled to move the multiple top columns 18 in the opposite direction away from the ball 13, so that the ball 13 can reduce the obstruction of the multiple top columns 18 to the ball 13 during the installation process. After the lubricating fluid inside the cotton belt 22 is consumed, the lubricating fluid inside it is difficult to flow directly to the surface of the ball 13. At this time, the sliding column 61 can be pressed to drive the pressure plate 62 to squeeze the cotton pad 21, and then the residual lubricating fluid inside the cotton pad 21 is squeezed onto the surface of the ball 13.
