Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a rotatable and adjustable floor lamp. Background Art

[0002] In modern home life, floor lamps, as important lighting fixtures, not only fulfill their basic function of providing light but also gradually incorporate elements of home decoration and personalized needs. With the development of technology, consumers' expectations for floor lamps are no longer limited to simple lighting effects, but are now more focused on their design, flexibility, and intelligence.

[0003] Most floor lamps currently on the market have fixed lighting angles and ranges. For example, a floor lamp disclosed in Chinese Utility Model Application No. 202320030736.8 can meet basic lighting needs, but has limitations in adapting to different scenarios and providing personalized adjustments. For example, traditional floor lamps typically have a single fixed lamp head and cannot adjust the lighting angle to suit the user's needs, resulting in insufficient light or excessive glare in certain areas or angles.

[0023] like Figures 1 to 3As shown, this embodiment discloses a rotatable and adjustable floor lamp, comprising a lamp holder 1, a lamp pole 2 fixedly mounted on the lamp holder 1, and a lamp head 3 rotatably mounted on the upper end of the lamp pole 2. The bottom end of the lamp pole 2 is fixedly connected to the rear of the lamp holder 1, specifically located at the center of the rear edge of the lamp holder 1. At the same time, the middle part of the lamp pole 2 protrudes toward the rear side of the lamp holder 1 so that the overall center of gravity moves backward, while the upper part of the lamp pole 2 extends horizontally forward. The lamp head 3 is mounted on the extended end of the upper part of the lamp pole 2. At this time, the lamp head 3 is located in front of the lamp holder 1 to maintain balance with the rearward-moved center of gravity. It includes an adapter column 31 installed at the upper extension end of the lamp pole 2, and the adapter column 31 extends vertically downward. A plurality of light-emitting panels 32 are rotatably engaged with the adapter column 31, and the plurality of light-emitting panels 32 are evenly spaced. Preferably, the center positions of the plurality of light-emitting panels 32 are rotatably engaged with the adapter column 31. In addition, in order to prevent the light-emitting panel 32 located below from blocking the light-emitting panel 32 above, the areas of the plurality of light-emitting panels 32 decrease from top to bottom, and the area of ​​the next light-emitting panel 32 is 60%-80% of the area of ​​the previous light-emitting panel 32.

[0024] In this embodiment, the extended end of the upper part of the lamp pole 2 is provided with a mounting hole 20 that passes through in the vertical direction, and the adapter column 31 passes through the mounting hole 20 from top to bottom. At the same time, the top of the adapter column 31 is provided with a limiting cap 311, and the limiting cap 311 is pressed against the edge position of the top of the mounting hole 20 to form a limit. The bottom of the adapter column 31 is fixedly connected to the lowest light-emitting panel 32. When the lowest light-emitting panel 32 rotates, the adapter column 31 can be driven to rotate, so that the lowest light-emitting panel 32 can be kept at a certain rotation angle. A locking structure 30 is provided on the inner wall of the mounting hole 20 and the outer wall of the adapter column 31. The locking structure 30 includes a plurality of limiting protrusions 301 provided on the inner wall of the mounting hole 20 and a plurality of locking protrusions 302 provided on the outer wall of the adapter column 31. The locking protrusions 302 are pressed against the limiting protrusions 301 to form a locking connection so that the light-emitting panel 32 is maintained at a certain angle. When the torque applied to the adapter column 31 is greater than a certain level, the locking protrusions 302 can be driven to slide relative to the limiting protrusions 301, thereby adjusting the angle of the light-emitting panel 32.

[0025] Furthermore, in order to avoid interference between two adjacent light-emitting panels 32, a spacer ring 33 is provided between the two adjacent light-emitting panels 32, and the spacer ring 33 is sleeved on the adapter column 31. Except for the lowest light-emitting panel 32, the remaining light-emitting panels 32 also need to keep the angle fixed. Therefore, a locking structure 30 is also provided at the position of the light-emitting panel 32 on the adapter column 31. The limiting protrusion 301 is provided on the inner side of the through hole in the middle of the light-emitting panel 32 for the adapter column 31 to pass through, and the locking protrusion 302 is provided on the outer wall of the adapter column 31.

[0026] Furthermore, in order to achieve continuous transmission of power while the light-emitting panel 32 rotates, a conductive slip ring 312 is provided at the joint between the top of the adapter column 31 and the mounting hole 20, and at the joint between the middle of the adapter column 31 and the light-emitting panel 32. The light-emitting panel 32 is connected to the power supply through the conductive slip ring 312, so that the light can be kept on while the light-emitting panel 32 rotates. In addition, the conductive slip ring 312 can be used to control multiple light-emitting panels 32 to light up individually or together, thereby changing the brightness of the light.

[0027] In this embodiment, the lamp pole 2 includes a first support rod 21, a second support rod 22 and a third support rod 23. The lower part of the first support rod 21 is fixedly connected to the lamp holder 1, the upper part of the first support rod 21 extends obliquely to the rear, the lower end of the second support rod 22 is connected to the top of the first support rod 21, the upper end of the second support rod 22 extends obliquely to the front and upward, one end of the third support rod 23 is connected to the front end of the second support rod 22, and the other end of the third support rod 23 extends horizontally forward. Preferably, the first support rod 21, the second support rod 22 The support rod 22 and the third support rod 23 are an integrally formed structure, which is specifically formed through a water expansion process. First, a special mold is designed and manufactured according to the shape and size of the required product, and then the pipe is placed in the mold and its two ends are sealed. Then, water is injected into the inside of the pipe through specific equipment and ultra-high pressure is applied. As water is injected and the pressure increases, the inner wall of the pipe is subjected to uniform pressure, begins to expand outward and gradually fills the space in the mold. This process has the advantages of high production efficiency, low cost, stable product quality, etc., and the structure is rounded and smooth, which can improve the aesthetics of the lamp pole 2.
