Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation desk lamp technology, specifically a telescopic magnetic levitation desk lamp. Background Technology

[0002] Magnetic levitation desk lamps combine magnetic levitation with wireless charging devices, allowing the lamp body to emit light while suspended in the air for decoration and illumination. However, current magnetic levitation desk lamps have fixed support rods, which take up transport space and increase transportation costs when transporting large quantities. Some magnetic levitation desk lamps use telescopic lamp rods, such as the telescopic magnetic levitation desk lamp disclosed in Chinese patent CN216743966U. This telescopic magnetic levitation desk lamp adjusts the height of the lamp base by setting a fixed rod and a telescopic rod, and then uses a clip assembly to fix the fixed rod and the telescopic rod. However, it cannot be infinitely adjusted; the telescopic rod can only be extended to the corresponding height. Utility Model Content

[0003] The purpose of this invention is to provide a telescopic magnetic levitation desk lamp to solve the problems mentioned in the background art.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a telescopic magnetic levitation desk lamp, including a base 1, a fixed cylinder 2 fixedly installed on the top of the base 1, a telescopic cylinder 3 slidably installed inside the fixed cylinder 2, a horizontal rod 4 fixedly installed on the top of the telescopic cylinder 3, a lamp holder 5 fixedly installed on the other end of the horizontal rod 4, a suspended lamp body 6 magnetically levitated below the lamp holder 5, and a lifting mechanism 7 provided inside the fixed cylinder 2 and the telescopic cylinder 3. By moving the telescopic cylinder 3 up and down to adjust the height of the horizontal rod 4, the height of the lamp holder 5 is adjusted. Therefore, the suspended lamp body 6 is connected to the lamp holder 5 by magnetic levitation. So when the height of the lamp holder 5 is adjusted, the height of the suspended lamp body 6 will also be adjusted. The height of the telescopic cylinder 3 is adjusted by the lifting mechanism 7.

[0021] The lifting mechanism 7 includes an extension cylinder 701 and a threaded rod 702. The extension cylinder 701 is fixedly installed on the top of the base 1. The bottom end of the threaded rod 702 is fixedly connected to the bottom inner wall of the fixed cylinder 2 via a bearing. The outer wall of the threaded rod 702 is threadedly connected to the bottom inner wall of the telescopic cylinder 3. The threaded rod 702 is driven by a drive shaft 704 via a helical gear set 703. The drive shaft 704 passes through the outer wall of the fixed cylinder 2 via a bearing and extends into the extension cylinder 701. The drive shaft 704 is driven by a rotating shaft 706 via a helical gear set 705. The top end of the rotating shaft 706 passes through the top inner wall of the extension cylinder 701 via a bearing. The extension cylinder 701 is set up to cover the transmission shaft 704, helical gear set 2 705, rotating shaft 706 and other structures, making the whole structure more aesthetically pleasing, and to protect the transmission shaft 704, helical gear set 2 705 and rotating shaft 706. The transmission is carried out by the transmission shaft 704, helical gear set 2 705, rotating shaft 706, helical gear set 1 703 and threaded rod 702, so that rotating the rotating shaft 706 can rotate the threaded rod 702, thereby causing the telescopic cylinder 3 to move up and down.

[0022] A knob 13 is fixedly installed on the top of the rotating shaft 706. The outer wall of the knob 13 is provided with anti-slip texture. The knob 13 makes it easier to rotate the rotating shaft 706 and makes the whole thing more aesthetically pleasing.

[0023] A controller 10 is installed inside the base 1. The controller 10 is electrically connected to the lamp holder 5 via a wiring harness. A control panel 11 is fixedly installed on the top of the base 1. The control panel 11 is electrically connected to the controller 10 via a wiring harness. By operating the control panel 11, instructions are sent to the controller 10, and the controller 10 then controls the lamp holder 5.

[0024] A power adapter 8 is fixedly installed inside the base 1, and a charging module 9 is fixedly installed on the base 1. The power adapter 8 is electrically connected to the controller 10, control panel 11, and lamp holder 5 through a wiring harness. The charging module 9 is electrically connected to the power adapter 8. The external power supply is connected to the power adapter 8 through the charging module 9 to supply power to the power adapter 8. The power adapter 8 supplies power to the controller 10, control panel 11, lamp holder 5, etc.

[0025] The control panel 11 is equipped with a touch screen 1101 and mechanical buttons 1102. Under normal operation, the touch screen 1101 can be used for operation, while the mechanical buttons 1102 can be used for opening and closing or in emergency situations (when the touch screen 1101 is damaged).

[0026] The telescopic cylinder 3 is provided with a wire harness channel 14, which is separated from the threaded rod 702. The inside of the telescopic cylinder 3 is connected to the inside of the horizontal rod 4, and the inside of the wire harness channel 14 is connected to the inside of the lamp holder 5, ensuring that the wire harness connecting the controller 10 and the lamp holder 5, as well as the wire harness connecting the power adapter 8 and the lamp holder 5, can pass through the fixed cylinder 2, the telescopic cylinder 3, and the horizontal rod 4.

[0027] Working principle: In use, rotating the knob 13 drives the rotating shaft 706 to rotate. The rotation of the rotating shaft 706 drives the transmission shaft 704 to rotate through the second helical gear set 705. The rotation of the transmission shaft 704 drives the threaded rod 702 to rotate through the first helical gear set 703. The rotation of the threaded rod 702 causes the telescopic cylinder 3 to move up or down, which in turn drives the horizontal rod 4 to move. The movement of the horizontal rod 4 drives the lamp holder 5 to move, adjusting the vertical height of the lamp holder 5, and thus adjusting the vertical height of the suspended lamp body 6.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
