Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3This utility model discloses a desk lamp, including a base 1, a lamp housing 2, and an upper support 3. A magnet 4 is embedded in the bottom of the base 1, and an iron sheet 5 is magnetically connected to it via the magnet 4. A nano-film 6 is adhered to the bottom of the iron sheet 5. A rechargeable battery 7 and a battery control board 8 are installed inside the base 1. The lamp housing 2 is tightly fitted onto the base 1, and a power display module 9 is embedded in the lamp housing 2. Sleeves 10 are provided around the base 1, and movable rods 11 are provided around the upper support 3. Spring steel balls 12 are evenly distributed on the movable rods 11. The movable rods 11 and sleeves 10 are interlocked, providing a telescopic adjustment function with the cooperation of the base 1 and the upper support 3. This allows the desk lamp to be adjusted to a suitable height during use and when not in use. It can also be easily folded, saving space and making it easy to store and carry. Due to the adsorption of the bottom magnet 4, and in conjunction with the iron sheet 5 with nano glue, users can easily fix the table lamp in a designated position without complicated installation steps. Installation and disassembly are very convenient. When the lighting position needs to be changed, simply move the table lamp to the metal surface. The upper support 3 has a metal spiral sleeve 13 embedded in the middle, and a metal spring 14 is provided at the lower part of the metal spiral sleeve 13. The upper support 3 is threadedly connected to the bulb 15 through the metal spiral sleeve 13. The metal spiral sleeve 13 and the metal spring 14 are electrically connected to the battery control board 8 through wires. The rechargeable battery 7 and the power display module 9 are electrically connected to the battery control board 8.

[0019] Specifically, the battery control board 8 is provided with a switch button 16 and a charging interface 17, and the switch button 16 and the charging interface 17 extend outward from the lamp housing 2.

[0020] In this embodiment, the battery control board 8 is a control board capable of controlling the charging and discharging of the battery. Its main functions include: charging control, where the control board controls the charging current and voltage parameters of the battery through a charging management chip to ensure the safe and reliable charging process and prevent overcharging and undercharging; discharging control, where the control board controls the battery output current and voltage through an output management chip to ensure the stability and reliability of the output; battery protection, where the control board uses a battery protection chip to protect the battery from overcharging, over-discharging, overcurrent, and short circuits, thereby improving the battery's lifespan; and status detection, where the control board monitors the battery's charge, temperature, and voltage. The system monitors the battery status to ensure optimal battery operation and extend battery life. It also includes data logging and fault diagnosis; some control boards have a data logging function to store battery usage history and diagnose battery malfunctions. The switch button 16 controls the battery's power output. Under normal conditions, pressing the button twice connects the lamp to the power supply, while pressing it once disconnects the power. The charging interface 17 is used for power transmission, facilitating timely replenishment of the lamp's power when it is low. The main function of the power display module 9 is to display the battery's power status in real time, helping users better manage and use the battery.

[0021] Specifically, the top of the lamp housing 2 is provided with a sleeve 18, and the upper support 3 is movably engaged in the sleeve 18.

[0022] In this embodiment, the sleeve 18 is an assembly structure to facilitate the assembly between the upper support 3 and the lamp housing 2.

[0023] Specifically, the movable rod 11 is positioned corresponding to the sleeve 10, and the spring steel ball 12 is located on one diagonal pair of the four movable rods 11.

[0024] In this implementation plan, such as Figure 2 and Figure 3 As shown, when the spring steel ball 12 protrudes from the sleeve 10, it provides the necessary support force for the movable rod 11. The elastic properties of the spring steel ball 12 enable the movable rod 11 to fit tightly inside the sleeve 10, thus achieving a damping effect.

[0025] Specifically, the sleeve 10 has a strip hole 19, and the bottom end of the movable rod 11 is inlaid with a limiting post 20, which is movably inserted into the strip hole 19.

[0026] In this implementation plan, such as Figure 2 and Figure 3 As shown, the engagement of the limiting post 20 and the strip hole 19 is used to prevent the movable rod 11 from disengaging from the sleeve 10.

[0027] Specifically, the limiting post 20 is located on another set of diagonal corners among the four movable rods 11, and the strip hole 19 is located on one set of diagonal corners among the four sleeves 10, corresponding to the position of the limiting post 20.

[0028] In this implementation plan, such as Figure 2 and Figure 3 As shown, when the movable lever 11 rises to its maximum stroke, the limiting post 20 is used to limit the movement.

[0029] When using bulb 15, it's important to note that it mainly consists of a filament, a glass housing, and a lamp holder. The metal parts of bulb 15 are conductors, while the glass housing and the plastic parts of the lamp holder are insulators. It's designed based on the principle of the heating effect of electric current. When bulb 15 is connected to its rated voltage, the current flows through the filament, heating it to incandescence (above 200°C), thus producing light. The outer side of the lamp holder is generally made of metal and is used to fix bulb 15 to the lamp base (upper support 3) and connect it to the power supply, allowing current to flow to the filament. The metal screw sleeve 13, located inside the lamp base (upper support 3), is the threaded part and is usually made of conductive metal (such as copper or nickel-plated material). It makes tight contact with the screw thread of bulb 15 to form a circuit. In standard installation, the screw sleeve is connected to the neutral wire (not the live wire). To prevent users from touching live parts and causing electric shock when replacing bulb 15, a metal spring 14 is located at the center of the bottom of the lamp holder (upper support 3). It maintains its elasticity through a spring structure, ensuring close contact with the metal block at the bottom of bulb 15. It is usually connected to the live wire, and the current completes the circuit through the spring 14 → lamp holder → filament → spiral sleeve → neutral wire. With the cooperation of the movable rod 11 and the sleeve 10, it has a telescopic adjustment function, which not only allows the lamp to be adjusted to a suitable height when in use, but also allows it to be easily folded when not in use, saving space and making it easy to store and carry. Due to the adsorption of the bottom magnet 4, in conjunction with the iron sheet 5 with nano-adhesive, users can easily fix the lamp in a designated position without complicated installation steps. Installation and disassembly are very convenient. When it is necessary to change the lighting position, simply move the lamp to the metal surface.

[0030] In summary, this desk lamp, with the cooperation of the base 1 and the upper support 3, has a telescopic adjustment function, which not only allows the desk lamp to be adjusted to a suitable height when in use, but also allows it to be easily folded when not in use, saving space and making it easy to store and carry. Due to the adsorption of the bottom magnet 4, in conjunction with the iron sheet 5 with nano-adhesive, users can easily fix the desk lamp in a designated position without complicated installation steps. Installation and disassembly are very convenient. When it is necessary to change the lighting position, simply move the desk lamp to the metal surface.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
