[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Reference Figure 1-Figure 3 A universal dimming motor telescopic rod structure includes a rotating shaft 1, a fixed sleeve provided with a retaining ring 2 on the rotating shaft 1 and close to the bottom end of the rotating shaft 1, a vertically arranged threaded rod 3 is fixedly connected to the bottom end of the rotating shaft 1, an annular limiting groove 4 is opened on the rotating shaft 1 and is located directly above the retaining ring 2, two rubber worm gears 5 are fixedly provided on the rotating shaft 1 and are vertically arranged, the two rubber worm gears 5 are both located directly above the retaining ring 2 and are respectively located at the upper and lower ends of the limiting groove 4, the top end of the rotating shaft 1 is fixedly connected to a vertically arranged metal wire rod 6, and a clamping seat 7 is vertically provided at the bottom end of the threaded rod 3;
[0021] The outer wall of the rotating shaft 1 is provided with a sleeve 8, the bottom end of the sleeve 8 is fitted with the top end of the retaining ring 2 and the outer diameter of the retaining ring 2 is smaller than the outer diameter of the sleeve 8, two rubber worm gears 5 are located between the rotating shaft 1 and the sleeve 8, and the width of the two rubber worm gears 5 is smaller than the distance between the rotating shaft 1 and the sleeve 8. When the device rotates, the two rubber worm gears 5 will transfer the lubricant to the top end of the sleeve 8 from bottom to top. The rubber worm gear 5, which is smaller than the distance between the rotating shaft 1 and the sleeve 8, will cause the lubricant moving to the upper end to slowly fall to the bottom end along the inner wall of the sleeve 8, so that the lubricant will not accumulate at the bottom end of the sleeve 8, and can fully play a lubricating role. A threaded tube 9 is provided in the middle of the sleeve 8, and the thread of the threaded tube 9 is provided on the outer wall. Six vertically arranged plug rods 10 are fixedly connected to the outer wall of the sleeve 8 and are arranged in a ring shape with respect to the sleeve 8. The outer side walls of the insertion rod 10 are all arc-shaped and the bottom end of the insertion rod 10 is at the same height as the bottom end of the sleeve 8. A guide hole 11 is provided on the outer side wall of the sleeve 8, which is located just above the threaded tube 9 and close to the top of the sleeve 8. A sleeve 2 14 is movably sleeved on the sleeve 18. The inner side wall of the sleeve 2 14 is provided with a thread and can be threaded on the threaded tube 9. The top of the sleeve 8 is fixedly connected with a vertically arranged elastic sleeve 12 and fits with the top of the sleeve 2 14. The guide hole 11 is located between the threaded tube 9 and the elastic sleeve 12. The inner side of the top of the sleeve 2 14 can fit on the outside of the guide hole 11. Two vertically arranged positioning blocks 13 are fixedly connected to the outer side wall of the elastic sleeve 12 and are symmetrically arranged about the elastic sleeve 12. Two vertically arranged grooves are provided on the outer side wall of the elastic sleeve 12 and are located between the two positioning blocks 13.
[0022] When the device needs lubrication, remove the device from its connector, and then rotate the sleeve 2 14 downward. At this time, the thread at the bottom end of the sleeve 2 14 will be unscrewed from the threaded tube 9, and the guide hole 11 between the threaded tube 9 and the elastic sleeve 12 will be exposed. Lubricant is injected from the guide hole 11 into the space between the rotating shaft 1 and the sleeve 1 8. When the device is subsequently moved, the rubber worm gear 5 will rotate with the rotating shaft 1 to transfer the lubricant from bottom to top to various places in the sleeve 1 8. After injection, move the sleeve 2 14 upward and engage with the threaded tube 9 so that the inner wall of the sleeve 2 14 fits with the guide hole 11, closing the guide hole 11.
[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
