[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7 The utility model discloses a portable desk lamp, comprising a base 1 and a desk lamp body 2, wherein a main column 11 is arranged on the top of the base 1, and a secondary column 12 is movably arranged inside the main column 11, and a limiting groove 13 and a buckle groove 14 located above the limiting groove 13 are arranged on one side of the inner wall of the main column 11 and the secondary column 12, and a gooseneck tube 15 is movably arranged inside the secondary column 12, and a spring buckle 16 which is respectively slidably sleeved with the inside of the two limiting grooves 13 is arranged at the bottom of the gooseneck tube 15 and one side of the secondary column 12, and a lamp board 22 is arranged inside the desk lamp body 2, and a storage cavity 21 which is sleeved with the main column 11 is opened inside the desk lamp body 2, and a docking rod 24 which has one end extending to the inside of the secondary column 12 and sleeved with the gooseneck tube 15 is arranged inside the storage cavity 21, and the two limiting grooves 13 are arranged opposite to each other, see Figure 7 When the main column 11 and the auxiliary column 12 are used to support the table lamp body 2, the base 1 is held and the table lamp body 2 is pulled up. The spring buckle 16 on the auxiliary column 12 slides inside the limit groove 13. The limit groove 13 limits the rotation of the auxiliary column 12 through the spring buckle 16. When the auxiliary column 12 rises to the right position, a "click" sound is heard, so that the spring buckle 16 on the auxiliary column 12 is snapped into the buckle groove 14 on the main column 11, and the limit groove 13 on the auxiliary column 12 and the gooseneck are locked. The same is true for the spring buckle 16 at the bottom of the tube 15. The top of the spring buckle 16 is set with a limiter so that the secondary column 12 can be completely removed from the inside of the main column 11, which is convenient for later assembly. A limiter can also be installed later to prevent the secondary column 12 from being pulled out from the inside of the main column 11. The same is true between the gooseneck tube 15 and the secondary column 12. The wires between the light panel 22 and the control panel can be elastic wires, which are passed through the main column 11, the secondary column 12, the gooseneck tube 15 and the docking rod 24.

[0027] Specifically, the top of the gooseneck tube 15 and the inner bottom of the docking rod 24 are respectively provided with matching threaded sections. The gooseneck tube 15 is a common desk lamp accessory and has the characteristics of arbitrary bending and positioning. Pull the desk lamp body 2 up, and when the two threaded sections contact each other, rotate the desk lamp body 2 to make the two threaded sections engage with each other, thereby completing the connection between the docking rod 24 and the gooseneck tube 15.

[0028] Specifically, the lamp board 22 is semicircular, and there are two lamp boards 22 . The two lamp boards 22 are combined to form a circle and surround the outside of the storage cavity 21 .

[0029] Specifically, a battery pack 17 is disposed inside the base 1 and inside the main column 11. A control panel is disposed inside the base 1. The control panel integrates a charging interface and a switch button with one end extending to one side of the base 1. Figure 1 The switch button can be used to control the two light panels 22 to light up simultaneously or individually. When lit at the same time, the lighting range can be increased, which is convenient for users to use handheld or in different scenes, such as camping scenes. The battery pack 17 can increase the weight of the base 1. The table lamp body 2 is light, and the base 1 can support the table lamp body 2 without using the suction cup 18.

[0030] Specifically, the bottom of the base 1 is provided with at least one suction cup 18, the interior of the base 1 is provided with a negative pressure chamber 19 connected to the interior of the suction cup 18, the interior of the negative pressure chamber 19 is provided with a piston 192, the interior of the piston 192 is provided with an adjusting screw 191 for rotation, the adjusting screw 191 extends to one side of the base 1 away from the piston 192, the base 1 is fitted with a smooth desktop, the adjusting screw 191 is rotated, and the piston 192 is matched with the negative pressure chamber 19 due to its size. , and the piston 192 and the negative pressure chamber 19 are both square. When the adjusting rod is rotated forward and backward, the piston 192 will be squeezed to move forward or backward. After the suction cup 18 is fitted with the desktop, the adjusting screw 191 is rotated to drive the piston 192 to retreat and suck the air inside the suction cup 18, so that the suction cup 18 and the desktop are adsorbed more closely. Conversely, air can be added to the inside of the suction cup 18 to make the suction cup 18 detach from the desktop. The operation method is simple and quick. The adjusting screw 191 is rotatably arranged inside the base 1 through a bearing and will not move back and forth.

[0031] Specifically, the opposite ends of the two thread segments are provided with conical surfaces, and the design of the conical surfaces makes the thread segments more flexible when docking and avoids jamming.

[0032] Specifically, a lampshade 23 is embedded on the surface of the lamp.

[0033] Specifically, the top of the base 1 and the bottom of the desk lamp body 2 are respectively embedded with magnets 3 that attract each other. When the main column 11 and the auxiliary column 12 are not used to support the main body of the table, the magnets 3 can ensure the connection stability between the base 1 and the desk lamp body 2, and maintain good stability when used by hand or transported.

[0034] In summary, the portable desk lamp can raise the desk lamp body 2 through the main column 11, the auxiliary column 12, the gooseneck tube 15 and the docking rod 24, and the above components can be stored through the storage cavity 21, which is convenient for users to carry the desk lamp body 2 and hold the desk lamp body 2 for use. The stability of the base 1 is ensured by the suction cup 18, and the provision of two arc-shaped light panels 22 makes it convenient for users to control the lighting range according to the usage scenario, further ensuring the usability of the product.

[0035] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
