Description
Technical Field
[0001] The present invention relates to the technical field of floor lamp devices, and specifically relates to a floor lamp that can adjust the inclination angle and has a heat dissipation function. Background Technique
[0002] As an important part of home lighting, floor lamps are widely used in places such as living rooms and bedrooms. They can not only provide local lighting to meet the needs of people's reading, leisure and other activities, but also create a warm and comfortable space atmosphere through unique shapes and soft lighting, combining practicality and decoration.
[0003] However, during the long-term use of floor lamps, since a large amount of heat is generated when electrical energy is converted into light energy, and existing floor lamps usually rely only on natural ventilation for heat dissipation, it is difficult to effectively reduce the temperature of the lamps. Over time, the high temperature will accelerate the aging of the internal electronic components of the lamps, resulting in a shortened service life of the lamps, and may even pose potential safety hazards, affecting the normal use experience of users.

[0010] Further, the heat dissipation component includes a plurality of heat dissipation grooves formed in the outer wall of the lamp shade, and a plurality of heat dissipation holes are formed in the top of the lamp shade; wherein, cold air enters the lamp shade through the heat dissipation grooves, takes away the heat inside the lamp shade and the heat on the plurality of heat dissipation fins, then passes through the ventilation openings formed in the mounting plate and the heat conduction plate, and finally is discharged through the heat dissipation holes at the top of the lamp shade.
[0011] Further, the height adjustment component includes a support sleeve fixedly connected to the top of the base. A threaded rod is slidably connected to the inner wall of the support sleeve. The top end of the threaded rod extends to the outside of the support sleeve. The top end of the threaded rod is rotatably connected to an internal threaded sleeve.

[0015] The present invention has the following beneficial effects: (1) Through the heat dissipation mechanism of the present invention, specifically, when the lamp head generates heat after long-term operation, the heat generated by the lamp head is conducted by the heat conducting plate to the copper core column and the heat dissipation fins, and then the inclined heat dissipation grooves on the lampshade are used to guide the cold air to enter, take away the heat and discharge it through the top heat dissipation holes. Thus, in the case of natural ventilation, without additional energy consumption, through the efficient heat conduction and natural convection design, the temperature of the lamp head is quickly reduced, avoiding light decay and shortened service life caused by overheating, reducing the maintenance cost of the lamp, ensuring long-term stable lighting, and significantly improving the durability and safety of the floor lamp.
[0016] (2)When the present invention adjusts the height of the lamp head through the height adjustment mechanism, specifically, when adjusting the height of the lamp head, the internal thread sleeve is rotated, and the threaded rod is driven to slide in the support sleeve by screw transmission. The movement range of the threaded rod is accurately limited by the cooperation of the limit block and the limit groove. This mechanism is easy to operate and does not require complex tools. Users can flexibly adjust the height of the lamp head according to their needs to adapt to various scenarios such as reading and working. At the same time, the limit design prevents structural damage caused by excessive lifting and lowering, improving the use stability and convenience.
[0017] (3)When the present invention adjusts the angle of the lamp head through the angle adjustment mechanism, specifically, when adjusting the angle of the lamp head, the support rod is rotated to change the tilt angle of the lamp head. After the adjustment is completed, the bidirectional threaded rod is driven by rotating the knob, so that the groove of the locking plate is engaged with the convex block of the fixed plate to achieve free adjustment and firm locking of the tilt angle of the lamp head, meeting the personalized needs of users for the light direction, such as local lighting and atmosphere creation. At the same time, the stable locking structure avoids angle deviation during use, ensuring accurate and reliable lighting effects.
[0018] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The height adjustment component 31 includes a support sleeve 311 fixedly connected to the top of the base 1. A threaded rod 312 is slidably connected to the inner wall of the support sleeve 311. The top end of the threaded rod 312 extends to the outside of the support sleeve 311.

[0030] The limiting component 32 includes a plurality of limiting grooves 321 formed on the inner wall of the support sleeve 311. The bottom end of the threaded rod 312 is fixedly connected with a plurality of limiting blocks 322. The one sides of the plurality of limiting blocks 322 away from the threaded rod 312 all extend to the inner walls of the corresponding limiting grooves 321 and are slidably connected with the corresponding limiting grooves 321. Among them, the plurality of limiting blocks 322 are fixedly connected with the threaded rod 312 by welding.
[0031] The connecting component 41 includes a connecting cylinder 411 fixedly connected to the top end of the threaded rod 312. A support rod 412 penetrates through the connecting cylinder 411. The support rod 412 is rotatably connected with the connecting cylinder 411. The support rod 412 is fixedly connected with the top of the lamp shade 11. Among them, the connecting cylinder 411 is fixedly connected with the threaded rod 312 by welding.
[0032] The locking component 42 includes a guide rod 421 fixedly connected to the inner wall of the connecting cylinder 411. Two locking plates 422 are slidably connected to the outer wall of the guide rod 421. A bidirectional threaded rod 423 penetrates through the connecting cylinder 411. The bidirectional threaded rod 423 is rotatably connected with the connecting cylinder 411. The bidirectional threaded rod 423 penetrates through the two locking plates ...... A fixing plate 424 is fixedly connected to the outer wall of the support rod 412. A plurality of bumps 425 are fixedly connected to the front side and the rear side of the fixing plate 424. A plurality of grooves 426 are formed on the one sides of the two locking plates 422 close to each other. Among them, when the two locking plates 422 move away from each other, the fixing plate 424 loses restraint. At this time, the angle of the lamp head 113 can be adjusted through the support rod 412.
[0033] During use, when using this device, when the lamp head 113 generates heat during operation, the heat conducting plate 211 contacts the lamp base 112, and quickly conducts the heat to the copper core column 212 and the heat dissipation fins 213. At this time, the heat dissipation grooves 221 on the outer wall of the lamp shade 11 that are inclined upward play a role. Using the principle of hot air rising, cold air is guided into the lamp shade 11. The cold air flows through the heat dissipation fins 213, taking away the heat on their surfaces, and at the same time dispersing the hot air accumulated in the lamp shade 11. This air carrying heat, under the condition of natural rising, passes through the ventilation holes on the mounting plate 111 and the heat conducting plate 211, and finally is discharged through the heat dissipation holes 222 evenly distributed at the top of the lamp shade 11, forming an efficient heat dissipation cycle to ensure the stable operation of the lamp head 113.
[0034] When it is necessary to adjust the height of the lamp holder 113, rotate the internally threaded sleeve 313. By virtue of the threaded connection characteristics between the internally threaded sleeve 313 and the threaded rod 312, and the sliding restriction of the slider 315 in the top chute 314 of the support sleeve 311, the rotation of the internally threaded sleeve 313 is converted into the up-and-down sliding of the threaded rod 312 within the support sleeve 311. At the same time, the limit block 322 at the bottom end of the threaded rod 312 slides within the limit groove 321 on the inner wall of the support sleeve 311, accurately limiting the movement range of the threaded rod 312. When the threaded rod 312 moves, it drives the connection cylinder 411 and the support rod 412 to move, and drives the lamp holder 113 to move through the lamp shade 11 connected to the support rod 412, thereby realizing the precise adjustment of the height of the lamp holder 113 and controlling its variation within the safe highest and lowest position ranges.
[0035] When adjusting the tilt angle of the lamp holder 113, rotate the support rod 412. Utilize the rotational connection structure between the support rod 412 and the connection cylinder 411 to make it rotate around the axis of the connection cylinder 411, thereby driving the lamp shade 11 and the lamp holder 113 to rotate synchronously to change the tilt angle. After the angle adjustment is in place, rotate the knob to drive the bidirectional threaded rod 423 to rotate, prompting the two locking plates 422 to move closer to each other. When the two locking plates 422 move, they will be guided by the guide rod 421 to ensure the stability of the movement of the two locking plates 422. At this time, the groove 426 on the locking plate 422 engages with the protrusion 425 on the fixing plate 424, forming a firm clamping on the fixing plate 424 and restricting the movement of the support rod 412, locking the lamp holder 113 at the adjusted tilt angle. If re-adjustment is required, rotate the knob in the reverse direction to move the locking plate 422 away and release the restraint on the fixing plate 424, then the angle of the lamp holder 113 can be adjusted again.

The preferred embodiments do not elaborate on all details nor limit the invention to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification.
