An internal thread groove 19 is provided on the inner ring, and a threaded rod 20 is threadedly connected to one end of the internal thread groove 19. A top cover 21 is fixedly connected to the upper end of the threaded rod 20. A second sleeve 22 is fixedly installed on the inner ring surface of the bottom cover 14 at equal intervals. A second movable rod 23 is penetrated and connected to one end of the second sleeve 22. A support rod 24 is fixedly installed on the surface of the inner ring of the bottom cover 14 adjacent to the second sleeve 22. One end of the support rod 24 is fixedly connected to a connecting frame 25. A slide groove 26 is provided on the surface of the extended section of the connecting frame 25. A slider 27 is provided at one end of the slide groove 26. A first connecting block 28 is fixedly installed on one side surface of the slider 27. A connecting rod 29 is sleeved and rotatably connected to one end of the first connecting block 28. A lighting lamp 32 is fixedly installed on the other side surface of the slider 27.

[0020] Furthermore, a first driving motor 2 is fixedly installed on the upper surface of one side of the inner wall of the box body 1, and the outer ring of the driving wheel 3 is provided with a synchronous belt 4, and one end of the synchronous belt 4 is provided with a driven wheel 5. A second driving motor 10 is fixedly installed on the inner compartment of the box body 1. Through the arrangement of the first driving motor 2 and the second driving motor 10, the first driving motor 2 can drive the driven wheel 5 to rotate above the box body 1, and the driven wheel 5 drives the driving wheel 3 to rotate through the synchronous belt 4. The rotation of the driving wheel 3 will drive the first sleeve 15 and the first movable rod 18 to rotate, and the first movable rod 18 will drive the bottom cover 14 to rotate on the outer ring of the connecting piece 13. The second driving motor 10 can drive the second bevel gear 9 to rotate, and the second bevel gear 9 drives the first bevel gear 8 to rotate, and the first bevel gear 8 drives the internal threaded tube 11 at the upper end of the central shaft 6 to rotate through the connecting shaft 7 Since the inner ring of the external threaded tube 12 is provided with an internal thread groove 19, and the internal thread groove 19 is connected to the top cover 21 through the threaded rod 20, and the top cover 21 is connected to the bottom cover 14 through the second movable rod 23 and the second sleeve 22, the rotation of the bottom cover 14 is controlled by the first drive motor 2, so that the rotation of the threaded rod 20 is controlled by the bottom cover 14. When the bottom cover 13 and the internal threaded tube 11 rotate in opposite directions, due to the friction between themselves and the friction generated between other connecting parts, the threaded rod 20 and the internal threaded tube 11 will generate a force with a resistance effect on each other, so that even when the connecting piece 13 and the bottom cover 14 are rotationally connected, the external threaded tube 12 will not rotate with the internal threaded tube 11 when the internal threaded tube 11 rotates. Therefore, when the internal threaded tube 11 rotates, the external threaded tube 12 drives the bottom cover 14 to rise and fall without affecting the rotation of the bottom cover 14.

[0021] Furthermore, the output end of the first drive motor 2 passes through the box body 1 and is fixedly connected to the driven wheel 5, and the output end of the second drive motor 10 passes through the inner partition of the box body 1 and is fixedly connected to the second bevel gear 9. Through the setting of the second bevel gear 9, the meshing process of the second bevel gear 9 and the first bevel gear 8 is continuous, the contact state between the tooth surfaces is good, and power can be effectively transmitted.

[0022] Furthermore, a limiting groove 16 is provided on the inner ring surface of the first sleeve 15, and a limiting block 17 is provided at one end of the limiting groove 16. The upper end of the limiting block 17 is fixedly connected to a first movable rod 18. Through the setting of the first movable rod 18, the first movable rod 18 slides on one end of the limiting groove 16 through the limiting block 17. When the bottom cover 14 is raised or lowered, the first movable rod 18 can be extended and retracted at one end of the first sleeve 15, and the limiting block 17 can limit the displacement travel distance.

[0023] Furthermore, the upper end of the second movable rod 23 is fixedly connected to the top cover 21, and the second movable rod 23 and the second sleeve 22 constitute a telescopic structure. The matching structure of the second movable rod 23 and the second sleeve 22 is the same as the matching structure of the first sleeve 15 and the first movable rod 18. Through the setting of the second movable rod 23, the second movable rod 23 can also slide at one end of the second sleeve 22, and through the rotation of the bottom cover 14, the threaded rod 20 at one end of the top cover 21 is driven to rotate at one end of the internal thread groove 19 for lifting and lowering.

[0024] Furthermore, a ring 30 is fixed on one end of the second movable rod 23, a second connecting block 31 is welded on one side surface of the ring 30, and a connecting rod 29 is rotatably connected to one end of the second connecting block 31. Through the setting of the connecting rod 29, the connecting rod 29 can push the lighting lamp 32 on one side of the slider 27 to move forward and backward by raising and lowering the second movable rod 23.

[0025] Furthermore, the outer rings of the top cover 21 and the bottom cover 14 are both provided with corresponding outer rings, and the slide groove 26 is a T-slot structure. Through the setting of the slide groove 26, the slide groove 26 can limit the movement of the slider 27, so that the lighting lamp 32 can maintain linear motion.

[0026] Furthermore, the thread structure of the internal threaded tube 11 is opposite to the thread structure of the internal threaded groove 19. Through the arrangement of the internal threaded tube 11 and the internal threaded groove 19, when the internal threaded tube 11 rotates, the external threaded tube 12 will rotate in the opposite direction, so that the external threaded tube 12 can be extended and retracted. Similarly, the internal threaded groove 19 and the external threaded tube 12 are an integrated structure. Because the internal threaded tube 11 and the external threaded tube 12 rotate in opposite directions, and the threaded rod 20 and the internal threaded tube 11 rotate in different directions, they can each achieve extension and retraction at both ends of the external threaded tube 12 under the cooperation of the corresponding threads.

[0027] Working principle: First, when lighting is needed, the second drive motor 10 drives the first bevel gear 8 at one end of the second bevel gear 9 to rotate, and the first bevel gear 8 drives the internal threaded tube 11 to rotate through the connecting shaft 7 and the central shaft 6. At the same time, the first drive motor 2 drives the driven wheel 5 to rotate, and the driven wheel 5 drives the driving wheel 3 to rotate through the synchronous belt 4. The driving wheel 3 and the internal threaded tube 11 rotate in opposite directions. The first sleeves 15 on both sides of the upper surface of the driving wheel 3 drive the first movable rod 18 to rotate. The first movable rod 18 Drive the bottom cover 14 to rotate, and at the same time, the bottom cover 14 drives the top cover 21 to rotate through the second sleeve 22 and the second movable rod 23, and the top cover 21 drives the threaded rod 20 to rotate in the opposite direction to the internal threaded tube 11. The threaded rod 20 and the internal threaded tube 11 rotate at the same time at both ends of the external threaded tube 12. The threaded rod 20 cooperates with the internal thread groove 19. Since the thread structure of the internal thread groove 19 and the internal threaded tube 11 are opposite, when the threaded rod 20 rotates in the same direction as the external threaded tube 12, the direction of rotation of the threaded rod 20 is opposite to that of the internal threaded tube 11. When the outer threaded tube 12 keeps the rotation position unchanged in the inner threaded tube 11, the outer threaded tube 12 is lifted at one end of the inner threaded tube 11, and the bottom cover 14 is lifted through the connecting piece 13. At the same time, the first movable rod 18 connected to the bottom cover 14 slides upward at one end of the first sleeve 15. When the limit block 17 contacts the inner upper end of the first sleeve 15, the bottom cover 14 is lifted and the bottom cover 14 continues to rotate. At this time, due to the action of the limit block 17, the outer threaded tube 12 has been lifted to a fixed position and cannot be lifted. When the rotation continues, When the bottom cover 14 is in the bottom cover 14, the top cover 21 above the bottom cover 14 drives the threaded rod 20 to continue to rotate. When the threaded rod 20 rotates at one end of the external threaded tube 12, it drives the top cover 21 to lift upward. When the top cover 21 is lifted, it drives the second movable rod 23 to lift upward at one end of the second sleeve 22. At the same time, the second movable rod 23 drives the connecting rod 29 to lift. The other end of the connecting rod 29 drives the slider 27 to slide from the inside to the outside at one end of the connecting frame 25 through the first connecting block 28, thereby driving the lighting lamp 32 on the other side of the slider 27 to be exposed for lighting.

[0028] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
