[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Reference Figures 1 to 11 As shown, to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a desktop lamp, comprising a lamp holder 1, a lamp body assembly 2, and a mounting plate 3, wherein the mounting plate 3 is arranged in an increasing manner along its length direction, and the mounting plate 3 is assembled from a plurality of mounting strips, and magnetic elements 4 are provided at both ends of the mounting strips;

[0037] The lamp holder 1 is provided with an adjustment rod 11, a return spring 12, an adjustment chamber 13, and a sliding chamber 14. The return spring 12 is installed in the sliding chamber 14. The adjustment rod 11 is slidably connected to the sliding chamber 14 and is arranged in conjunction with the return spring 12. The adjustment chamber 13 is located at the lower end of the sliding chamber 14 and is connected to the sliding chamber 14.

[0038] The lower end of the adjustment rod 11 extends into the adjustment cavity 13, and the lamp body assembly 2 is installed on the upper end of the adjustment rod 11;

[0039] The lamp holder 1 is slidably connected to the mounting plate 3. When the lamp holder 1 moves from a low position to a high position along the mounting plate 3, the adjustment rod 11 abuts against the mounting plate 3 and slides upward.

[0040] The lamp body assembly 2 includes a lamp body rod 21, a bulb 22, a shading member 23 and a transmission member 24. One end of the lamp body rod 21 is connected to the adjusting rod 11. A light emitting hole 211 is provided on the lamp body rod 21. The bulb 22 is arranged in the lamp body rod 21 and corresponds to the light emitting hole 211. The shading member 23 is used to block the light emitting hole 211, and the shading member 23 is linked to the transmission member 24. A driving member 15 is provided on the adjusting rod 11, and the driving member 15 is cooperated with the transmission member 24. When the adjusting rod 11 moves along the sliding cavity 14, the driving member 15 causes the effective light emitting area of ​​the light emitting hole 211 to change through the transmission member 24.

[0041] The design of the present invention is as follows: the mounting strip is fixed on the desktop according to the equipment installation manual. The specific fixing method is to install it at an angle along the corner of the desktop, and it can form a 30° angle with the upper edge of the desktop. Then the desk lamp is slid and fitted on the mounting plate 3. At this time, the lower the position of the adjustment rod 11, the smaller the effective light-emitting area of ​​the light-emitting hole 211, and the smaller the light irradiation area. When the lamp holder 1 slides from a low position to a high position along the mounting plate 3, the adjustment rod 11 moves upward. At this time, the driving member 15 and the transmission member 24 increase the effective light-emitting area of ​​the light-emitting hole 211, thereby increasing its irradiation range.

[0042] The desktop lamp can intelligently adjust the lighting range in the process of adjusting the relative position of the desk lamp after the position is set.

[0043] A further method of fixing the mounting strip is to provide a small suction cup at the bottom of the mounting strip to form a negative pressure connection with the desktop, or to connect one of the mounting strips to the desktop with tape. At this time, the other mounting strips can be magnetically connected in turn, thereby forming a basic fixation.

[0044] The present invention is further configured as follows: the light shielding member 23 includes a light shielding disc 231, a light shielding plate 232, and a rotating ring 233. The light shielding disc 231 is installed in the lamp body rod 21. The rotating ring 233 is rotatably connected to the light shielding disc 231. The light exit hole 211 is directly opposite to the middle of the light shielding disc 231.

[0045] There are multiple sets of light shielding plates 232, which are arranged in a circular pattern on the light shielding disc 231. One end of the light shielding plate 232 is rotatably connected to the light shielding disc 231, and the other end is connected to the rotating ring 233. When the rotating ring 233 rotates, the light shielding plate 232 is used to block the light exit hole 211. The light shielding member 23 adopts an aperture adjustment structure, such as Figure 4 and Figure 5 As shown, during the rotation of the rotating ring 233 , the light shielding plate 232 will rotate accordingly, and the size of the central hole will change through the cooperation of multiple groups of light shielding plates 232 .

[0046] The present invention is further configured as follows: the transmission member 24 includes a transmission gear 241, a transmission wheel 242, and a transmission belt 243. The transmission belt 243 is respectively wound around the transmission wheel 242 and the rotating ring 233. When the transmission wheel 242 rotates, the rotating ring 233 is driven to rotate through the transmission belt 243.

[0047] The transmission gear 241 is fixedly connected to the transmission wheel 242 .

[0048] like Figure 6 As shown, when the transmission gear 241 rotates, since the transmission gear 241 and the transmission wheel 242 are fixedly connected, the transmission wheel 242 rotates with the rotation of the transmission gear 241. At this time, the transmission effect of the transmission belt 243 causes the rotating ring 233 to rotate.

[0049] like Figure 6 As shown, the rotating ring 233 is provided with a winding groove for the transmission belt 243 to be wound around.

[0050] The present invention is further configured as follows: the driving member 15 includes a driving rack 151 . The driving rack 151 is mounted on the outer wall of the adjusting rod 11 and is meshed with the transmission gear 241 .

[0051] like Figure 7 As shown, when the adjusting rod 11 moves upward, the transmission gear 241 can be rotated through the meshing relationship between the driving gear and the transmission gear 241.

[0052] The present invention is further configured as follows: multiple sets of light shielding members 23, bulbs 22 and transmission belts 243 are provided, light shielding members 23 and bulbs 22 are provided in a one-to-one correspondence, and two adjacent rotating rings 233 are provided in linkage via the transmission belts 243. Figure 10 As shown, in the design of this structure, two sets of winding grooves are provided on each rotating ring 233, and the linkage of two adjacent rotating rings 233 is achieved through staggered winding.

[0053] The present invention is further configured as follows: at least two mounting bars are provided, namely a first mounting bar 31 and a second mounting bar 32. The first mounting bar 31 is provided with a first platform 311 and a first guide platform 312. The second mounting bar 32 is provided with a second platform 321 and a second guide platform 322. The second platform 321 is provided higher than the first platform 311.

[0054] A first limiting member 5 and a second limiting member 6 are respectively provided at one end where the first mounting bar 31 and the second mounting bar 32 are in contact with each other.

[0055] like Figure 1 As shown, the design of the first guide platform 312 and the second guide platform 322 can form a sliding fit between the first installation bar 31, the second installation bar 32 and other installation bars along the guide surface.

[0056] The design of the first platform 311 and the second platform 321 can ensure the stability of the base and prevent displacement.

[0057] The present invention is further configured as follows: the second limiting member 6 includes a limiting rod 51 and a limiting spring 52, a limiting groove 323 is provided on the second mounting bar 32, the limiting rod 51 is slidably connected to the limiting groove 323 through the limiting spring 52, and an end of the second mounting bar 32 close to the second platform 321 is provided with a socket 33 connected to the limiting groove 323.

[0058] The present invention is further configured as follows: the first limiting member 5 includes an inserting block 61 for inserting into the insertion hole 33, the limiting rod 51 is provided with a tapered slot 53, and the inserting block 61 is provided with a tapered inserting surface

[0059] The design of the structure, combined with Figure 1 and Figure 2 as well as Figure 8 As shown, when the first limiting member 5 and the second limiting member 6 cooperate, the limiting rod 51 extends downward, and when the first limiting member 5 and the second limiting member 6 separate, the limiting rod 51 extends upward.

[0060] Specific cooperation methods such as Figure 8 As shown, when the insert block 61 is inserted into the insert hole 33 , the tapered insert surface and the tapered slot 53 cooperate to cause the limiting rod 51 to move downward and compress the limiting spring 52 .

[0061] When the inserting block 61 is separated from the inserting hole 33 , the limiting rod 51 extends upward under the action of the limiting spring 52 .

[0062] The limiting rod 51 prevents the adjusting rod 11 from moving to a lower position, and the guide platform restricts the adjusting rod 11 from moving to a higher position.

[0063] The design of the magnetic element 4 enables quick connection and disconnection between multiple mounting strips, and enables assembly at multiple angles, thus enabling DIY design of desktop mounting strips.

[0064] The present invention is further configured as follows: the mounting strips each include a strip seat 7 and a strip plate 8 , the strip plate 8 is rotatably connected to the strip seat 7 , and both the strip plate 8 and the strip seat 7 are provided with a semicircular wire hole 71 .

[0065] The design of this structure can facilitate the installation of data cables and plug cables. In the original design, the characteristics of the device are enhanced, different effects are achieved, and the length of the original installation plate 3 can be reduced, allowing for flexible desktop layout.

[0066] The present invention is further configured as follows: the mounting bar includes a platform portion and a guide portion, and the guide portion is rotatably connected to the platform portion via a damping shaft.

[0067] The design of the structure, such as Figure 9 As shown, taking the first mounting bar 31 as an example, the positional relationship between the first platform 311 and the first guide platform 312 can be adjusted, which is more flexible.

[0068] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
