If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] It is understandable that, referring to Figures 1 to 6 The utility model is a foldable desk lamp, comprising a light source assembly 100, a first rotating assembly 200, a second rotating assembly 300 and a third rotating assembly 400, wherein the light source assembly 100 is used for emitting light; the first rotating assembly 200 comprises a base 210 and a support rod 220, wherein the base 210 is provided with a mounting portion 230 and a limiting portion 240, wherein the mounting portion 230 is provided with a guide groove 231 in a vertical direction, wherein a first rotating shaft 221 is provided at one end of the support rod 220, wherein the first rotating shaft 221 is slidably connected to the guide groove 231, and the first rotating shaft 221 can rotate in the guide groove 231, wherein the limiting portion 240 is arranged adjacent to the guide groove 231, and ... The two side walls of the part 240 and the mounting part 230 facing each other can respectively abut against the opposite sides of the support rod 220 to limit the rotation of the support rod 220; the second rotating assembly 300 includes a rotating bracket 310 and a damper 320, and the rotating bracket 310 is rotatably connected to the end of the support rod 220 away from the mounting part 230 through the damper 320, and the rotating bracket 310 can rotate in the direction close to or away from the support rod 220; the third rotating assembly 400 includes a lamp holder 410, which is rotatably connected to the rotating bracket 310, and the lamp holder 410 can rotate around the length direction of the lamp holder 410, and the light source assembly 100 is arranged on the lamp holder 410.

[0036] Since the rotating bracket 310 is rotatably connected to the end of the support rod 220 away from the mounting portion 230 through the damper 320, the lamp holder 410 is rotatably connected to the rotating bracket 310, so that the rotating bracket 310 can drive the lamp holder 410 to rotate in the direction close to the support rod 220, and since the mounting portion 230 is provided with a guide groove 231 in the vertical direction, the first rotating shaft 221 is slidably connected to the guide groove 231, and the first rotating shaft 221 slides vertically upward along the guide groove 231 to drive the support rod 220 to move vertically upward, and at the same time, the support rod 220 rotates around the axial direction of the first rotating shaft 221 in the direction close to the base 210, so as to realize the lamp holder 410 The folding storage of the support rod 220 reduces the occupied space and facilitates storage. After the support rod 220 rotates around the axial direction of the first rotating shaft 221, the first rotating shaft 221 slides vertically downward along the guide groove 231. The two side walls facing each other through the limiting part 240 and the mounting part 230 respectively abut the opposite sides of the support rod 220 to limit the rotation of the support rod 220, and the expansion angle of the support rod 220 can be fixed. After the rotating bracket 310 drives the lamp holder 410 to rotate and unfold, the expansion angle of the lamp holder 410 is fixed by the damping effect of the damper 320, thereby reducing the possibility of the expansion angle of the support rod 220 and the lamp holder 410 changing. In addition, since the lamp holder 410 is rotatably connected to the rotating bracket 310, the lamp holder 410 rotates around the length direction of the lamp holder 410, and cooperates with the rotating bracket 310 to drive the lamp holder 410 to rotate, the irradiation angle can be adjusted from two different directions at multiple angles to meet different lighting needs, thereby improving the user experience.

[0037] It should be noted that the torque of the damper 320 increases with the increase of the rotation speed. When the rotating bracket 310 drives the lamp holder 410 to rotate toward the direction close to the support rod 220, it can play a rotation buffering role, reducing the risk of damage caused by collision between the lamp holder 410 and the support rod 220, thereby extending the service life of the foldable desk lamp.

[0038] The vertical height of the mounting portion 230 abutting against the side wall of the support rod 220 can be greater than the vertical height of the limiting portion 240 abutting against the side wall of the support rod 220, so that the support rod 220 can still abut against the side wall of the mounting portion 230 when it is separated from the side wall of the limiting portion 240, so as to limit the maximum rotation and expansion angle of the support rod 220, thereby facilitating the positioning of the maximum expansion angle of the support rod 220, and can guide the support rod 220 to move vertically downward to fix the rotation and expansion angle of the support rod 220.

[0039] It is understandable that, referring to Figure 3 and Figure 6A limiting block 222 is provided at one end of the support rod 220 close to the mounting portion 230, and a limiting groove 232 is provided on the side wall of the mounting portion 230 toward the limiting portion 240. The limiting block 222 can extend into the limiting groove 232, and the limiting block 222 can abut against the top wall of the limiting groove 232. When the limiting block 222 abuts against the top wall of the limiting groove 232, the support rod 220 can abut against the upper end surface of the limiting portion 240 to limit the support rod 220 from rotating in the direction close to the base 210. Since a limiting block 222 is provided at one end of the support rod 220 close to the mounting portion 230, a limiting groove 232 is provided on the side wall of the mounting portion 230 toward the limiting portion 240. When the support rod 220 is folded by axial rotation around the first rotating shaft 221, the limiting block 222 extends into the limiting groove 232 and abuts against the top wall of the limiting groove 232. At the same time, the support rod 220 abuts against the upper end surface of the limiting portion 240, which can limit the rotation of the support rod 220 to locate the maximum folding rotation angle of the support rod 220, thereby reducing the possibility of the support rod 220 colliding with the base 210 and being damaged when driving the lamp frame 410 to rotate and fold, thereby extending the service life of the foldable desk lamp.

[0040] It should be noted that the first rotating shaft 221 can also abut the top wall of the guide groove 231. When the first rotating shaft 221 abuts the top wall of the guide groove 231, the support rod 220 can abut the upper end surface of the limiting portion 240, thereby limiting the rotation of the support rod 220 to position the maximum folding rotation angle of the support rod 220.

[0041] It is understandable that, referring to Figure 2 and Figure 6 The first rotating shaft 221 is provided with a guide surface 223, and the guide surface 223 is inclined from bottom to top in a direction away from the support rod 220. Since the guide surface 223 is inclined from bottom to top in a direction away from the support rod 220, when the support rod 220 is installed on the mounting portion 230 from top to bottom, the guide surface 223 abuts against the mounting portion 230, and the first rotating shaft 221 can be guided to gradually slide into the mounting portion 230 and be clamped in the guide groove 231, which facilitates the clamping and installation of the support rod 220 on the mounting portion 230, reduces the assembly difficulty of the support rod 220 and improves the assembly efficiency.

[0042] It should be noted that the portion of the support rod 220 where the first rotating shaft 221 is set is elastic. When the guide surface 223 abuts against the mounting portion 230, elastic deformation can be generated, causing the first rotating shaft 221 to move along the normal direction of the guide surface 223. When the first rotating shaft 221 moves to the position of the guide groove 231, it can elastically recover, causing the first rotating shaft 221 to be clamped in the guide groove 231, thereby allowing the first rotating shaft 221 to gradually slide into the mounting portion 230 and be clamped in the guide groove 231.

[0043] It is understandable that, referring to Figure 2 and Figure 6The base 210 includes a surface shell 211 and a bottom shell 212. The surface shell 211 is clamped on the bottom shell 212. The guide groove 231 is set as an open groove, and the opening of the guide groove 231 is connected to the inside of the surface shell 211. By setting the guide groove 231 as an open groove, and the opening of the guide groove 231 is connected to the inside of the surface shell 211, the first rotating shaft 221 can enter the inside of the surface shell 211 from the opening of the guide groove 231, and by removing the bottom shell 212 from the surface shell 211, the support rod 220 can be removed from the bottom of the surface shell 211, which is convenient for the removal and replacement of the support rod 220. In addition, the first rotating shaft 221 abuts against the top wall of the guide groove 231 to limit the vertical upward sliding of the first rotating shaft 221, reducing the risk of the support rod 220 detaching from the top of the mounting portion 230, thereby improving the assembly stability of the support rod 220.

[0044] Specifically, refer to Figure 2 and Figure 3 The bottom shell 212 is vertically provided with two support columns 213, and the two support columns 213 can abut against the support rod 220 at the same time to support the support rod 220. The two support columns 213 abut against the support rod 220 at the same time to support the support rod 220, so that the force on the bottom of the support rod 220 is balanced, the deployment stability of the support rod 220 is improved, and the vertical downward movement of the support rod 220 can be limited, and the top wall of the guide groove 231 is cooperated to facilitate the positioning of the vertical movement of the support rod 220.

[0045] It is understandable that, referring to Figure 2 , Figure 5 and Fig. 9The second rotating assembly 300 also includes a second rotating shaft 330, the support rod 220 is provided with a first connecting portion 224, the first connecting portion 224 is provided with a first positioning hole 225 and a second positioning hole 226, the first positioning hole 225 and the second positioning hole 226 are coaxially arranged, the rotating bracket 310 is provided with a first mounting hole 311 and a second mounting hole 312, the first mounting hole 311 and the second mounting hole 312 are coaxially arranged, one end of the second rotating shaft 330 is clamped in the first positioning hole 225, the other end of the second rotating shaft 330 is penetrated into the first mounting hole 311, the fixed end of the damper 320 is clamped in the second positioning hole 226, and the movable end of the damper 320 is clamped in the second mounting hole 312. Since the first positioning hole 225 and the second positioning hole 226 are coaxially arranged, and the first mounting hole 311 and the second mounting hole 312 are coaxially arranged, by aligning the first positioning hole 225 with the first mounting hole 311 and making the first positioning hole 225 and the first mounting hole 311 coaxial, the second rotating shaft 330 and the damper 320 can be easily aligned with the assembly position, and the second rotating shaft 330 can be assembled by clamping one end of the second rotating shaft 330 in the first positioning hole 225 and the other end of the second rotating shaft 330 through the first mounting hole 311, and the damper 320 can be assembled by clamping the fixed end of the damper 320 in the second positioning hole 226 and the movable end of the damper 320 in the second mounting hole 312, which can simplify the assembly structure and reduce the difficulty of assembly, and at the same time, it is convenient to disassemble and replace the second rotating shaft 330 and the damper 320.

[0046] Specifically, refer to Figure 2 , Figure 3 and Figure 8 The lamp holder 410 is provided with a connection slot 411, and the rotating bracket 310 is provided with a second connection portion 313, and the second connection portion 313 is rotatably connected to the connection slot 411, and the shape of the connection slot 411 matches the shape of the second connection portion 313. Since the shape of the connection slot 411 matches the shape of the second connection portion 313, when the lamp holder 410 rotates around the length direction of the lamp holder 410, the second connection portion 313 can be closely attached to the wall surface of the connection slot 411, thereby reducing the position deviation of the lamp holder 410, thereby improving the rotation stability of the lamp holder 410.

[0047] Specifically, refer to Figure 5 , Figure 8 and Fig. 9The third rotating assembly 400 further includes a bolt 420 and a nut 430. The second connecting portion 313 is provided with a third mounting hole 314, which is perpendicular to the axial direction of the first mounting hole 311. The nut 430 is fixedly connected to the lamp holder 410. The bolt 420 is inserted into the third mounting hole 314, and one end of the bolt 420 is threadedly connected to the nut 430, and the other end of the bolt 420 abuts against the lamp holder 410. By connecting the second connecting portion 313 to the connecting groove 411, inserting the bolt 420 into the third mounting hole 314, and threading one end of the bolt 420 to the nut 430, and the other end of the bolt 420 abuts against the lamp holder 410, the assembly of the rotating bracket 310 and the lamp holder 410 can be completed, which can simplify the assembly structure and improve the assembly efficiency. At the same time, since the nut 430 is fixedly connected to the lamp holder 410, the tightness of the assembly can be adjusted by simply turning the bolt 420, thereby facilitating the adjustment of the resistance to the rotation of the lamp holder 410. In addition, since the third mounting hole 314 is axially perpendicular to the first mounting hole 311, the rotation axis of the rotating bracket 310 is perpendicular to the rotation axis of the lamp holder 410, which facilitates multi-angle adjustment of the illumination angle from two mutually perpendicular directions, thereby increasing the adjustment range of the illumination angle to meet different lighting needs.

[0048] Specifically, refer to Figure 2 and Figure 5 The second rotating shaft 330 is provided with a third connecting portion 331 and a fourth connecting portion 332 at both ends, the third connecting portion 331 is clamped in the first positioning hole 225, the fourth connecting portion 332 is penetrated in the first mounting hole 311, and the aperture of the first positioning hole 225 is larger than the outer diameter of the fourth connecting portion 332. Since the aperture of the first positioning hole 225 is larger than the outer diameter of the fourth connecting portion 332, the fourth connecting portion 332 can pass through the first positioning hole 225 and be clamped in the first mounting hole 311, thereby facilitating the assembly of the second rotating shaft 330 from the first positioning hole 225, and since the aperture of the first positioning hole 225 matches the outer diameter of the third connecting portion 331, and the aperture of the first mounting hole 311 matches the outer diameter of the fourth connecting portion 332, that is, the outer diameter of the third connecting portion 331 is larger than the aperture of the first mounting hole 311, so as to prevent the third connecting portion 331 from penetrating into the first mounting hole 311, thereby enabling the second rotating shaft 330 to be positioned and installed, reducing the assembly difficulty.

[0049] It is understandable that, referring to Figure 2 and Figure 7The lamp holder 410 is provided with an escape groove 412, and the support rod 220 can extend into the escape groove 412. Since the lamp holder 410 is provided with the escape groove 412, when the lamp holder 410 rotates along the length direction of the lamp holder 410, the support rod 220 can extend into the escape groove 412, thereby expanding the rotation angle range of the lamp holder 410. In addition, the support rod 220 can abut against the wall surface of the escape groove 412 to limit the rotation of the lamp holder 410 along the length direction of the lamp holder 410, and can determine the maximum rotation angle of the lamp holder 410.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
