[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference Figure 1 As shown, the LED floor lamp 1000 that is convenient to adjust and lift according to an embodiment of the utility model includes a support rod 100, a lamp body 200, a lifting mechanism 300 and a base 400. The support rod 100 extends in the up-down direction, and the support rod 100 is a hollow structure. The base 400 is connected to the lower end of the support rod 100. The lamp body 200 is slidably connected to the support rod 100, and the lamp body 200 is provided with a fixed installation part 210. The lifting mechanism 300 includes a first pulley 310, a knob 320 and a rope 330. The first pulley 310 is provided at the upper end of the support rod 100. Figure 5 As shown, the knob member 320 includes a knob portion 321, a latch portion 322 and a shaft portion 323, the knob portion 321 is connected to the shaft portion 323, the latch portion 322 is connected to the knob portion 321, the outer peripheral wall of the support rod 100 is provided with a shaft hole 110 and a latch hole 120, the shaft portion 323 is rotatably matched with the shaft hole 110, the shaft portion 323 extends into the support rod 100, the knob portion 321 is located outside the support rod 100, and one end of the rope 330 is connected to the fixed The mounting part 210 is fixedly connected, and the other end of the rope 330 is fixedly connected to the shaft part 323. When the knob 320 is turned, the rope 330 will circumferentially wrap around the shaft part 323. The rope 330 is wound around the first pulley 310. The fixed mounting part 210 is located below the first pulley 310. The rope 330 passes through the top of the first pulley 310. The first pulley 310 can change the direction of the pulling force of the rope 330. The first pulley 310 acts as a fulcrum. The knob 320 has a locked state and an unlocked state. Figure 5 As shown, the knob 320 is in a locked state, and the latch portion 322 is inserted into the latch hole 120, so that the knob 320 can be locked and the knob 320 cannot be rotated. Figure 6 As shown, the knob 320 is in the unlocked state, and the latch portion 322 is out of the latch hole 120. The knob 320 can move along the axial direction of the shaft portion 323, so that it can be switched between the locked state and the unlocked state. Figure 1 As shown, the LED floor lamp 1000 is in the lowered position, referring to Figure 3 As shown, the LED floor lamp 1000 is in a raised position.

[0031] It should be noted that, under natural conditions, the knob 320 is in a locked state. At this time, the latch portion 322 is inserted into the latch hole 120, and the knob 320 cannot rotate. When it is necessary to adjust the lifting position of the lamp body 200, the knob 320 can be pulled out to make the latch portion 322 disengage from the latch hole 120. At this time, the knob 320 can rotate. When the knob 320 rotates, the rope 330 is pulled downward or released upward. When the knob 320 pulls the rope 330 downward, the rope 330 will fix the mounting portion. The position of 210 is lifted, that is, the position of the lamp body 200 is lifted. When the knob part 320 releases the rope 330 upwards, the lamp body 200 moves downward under the action of gravity, and the lamp body 200 will tighten the rope 330, thereby lifting or lowering the lamp body 200. After adjustment, the latch part 322 is aligned with the latch hole 120 and inserted to put the knob part 320 in a locked state to prevent the lamp body 200 from falling downward due to gravity. The knob part 320 only needs to be operated with one hand, which can facilitate the operation of adjusting the lifting and lowering and improve the user experience.

[0032] Reference Figure 1 As shown, according to some embodiments of the utility model, the lamp body 200 includes a lampshade 220, a lamp board 230 and a sliding sleeve 240. The lampshade 220 is a truncated cone structure. The lamp board 230 is fixed to the top wall inside the lampshade 220. The lighting effect is better. The lampshade 220 is fixedly connected to the sliding sleeve 240. The sliding sleeve 240 is an annular structure. The sliding sleeve 240 is sleeved on the outer periphery of the support rod 100. The sliding sleeve 240 is slidably connected to the support rod 100, so that the lampshade 220 can slide in the up and down directions.

[0033] Reference Figure 1 As shown, according to some embodiments of the present invention, the first pulley 310 is located in the support rod 100, and the outer peripheral wall of the support rod 100 is provided with a first avoidance hole 130 for the rope 330 to pass through, the first avoidance hole 130, the fixed installation part 210 is located below the first avoidance hole 130, and the rope 330 between the first pulley 310 and the fixed installation part 210 is located above the sliding sleeve 240. Figure 3 As shown, when the LED floor lamp 1000 is at the lifting limit position, the sliding sleeve 240 cannot continue to move upward due to the obstruction of the rope 330, which can play a limiting role and prevent the sliding sleeve 240 from separating from the support rod 100.

[0034] Reference Figure 1 and Figure 2 As shown, according to some embodiments of the utility model, from the radial outer side of the support rod 100 to the radial inner side of the support rod 100, the axis of the first avoidance hole 130 is inclined downward, so that the inner wall of the first avoidance hole 130 can follow the extension direction of the rope 330, reducing the resistance to the rope 330, making the lamp body 200 rise and fall more smoothly, and turning the knob 320 is more labor-saving.

[0035] Reference Figure 7 As shown, alternatively, in some other embodiments, a second avoidance hole 140 is provided at the upper end of the support rod 100 for the rope 330 to pass through, and the lifting mechanism 300 includes a second pulley 340, which is located in the lamp body 200, and the second pulley 340 is located above the first pulley 310, and the rope 330 is wound around the second pulley 340, and the rope 330 passes through the top of the second pulley 340, and the rope 330 passes through the first pulley 310, the second pulley 340 and the fixed installation part 210 in sequence, and the second pulley 340 can prevent the rope 330 from contacting with the support rod 100 or other structures to generate friction, and can reduce the resistance to the rope 330, so that the lamp body 200 can be lifted and lowered more smoothly, and turning the knob 320 can be more labor-saving.

[0036] According to some embodiments of the present invention, the lower end of the support rod 100 is threadedly connected to the base 400, so that the base 400 can be disassembled for easy packaging and transportation.

[0037] According to some embodiments of the utility model, a magnetic member is provided on the outer wall of the support rod 100, and the magnetic member is magnetically connected to the knob portion 321, so that the knob portion 320 can be kept in a locked state to prevent the latch portion 322 from being separated from the latch hole 120 due to vibration or other factors.

[0038] According to some embodiments of the present invention, a plurality of latch holes 120 are provided, and the plurality of latch holes 120 are arranged at intervals along the circumference of the shaft hole 110. The latch portion 322 can be inserted into one of the latch holes 120, which can ensure that the lifting position of the lamp body 200 is not greatly affected. Specifically, the number of the latch holes 120 is 6, and the 6 latch holes 120 are arranged at intervals of 60 degrees.
