[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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. Example

[0034] See Figures 1 to 6As shown, a floor lamp with adjustable lighting angle and height comprises a base 1, a hollow profile tube 2 fixed on the base, a lifting tube 3 is provided on the outer side of the hollow profile tube, a horizontal lamp holder 4 is fixed on the top of the lifting tube, and the end of the horizontal lamp holder is connected to the lamp body 6 through a universal joint 5; in this embodiment, the hollow profile tube can be a one-piece structure or a spliced ​​structural member, the lifting tube can also be a one-piece structure or a structure formed by splicing several side panels fixed by plug-ins or screws, and can be processed and set as needed, its universal joint is a conventional structure of the prior art, and is simply used, its horizontal lamp holder can be placed horizontally or tilted at a certain angle, as long as it is set horizontally, and its lamp body is a floodlight, downlight or spotlight; the lamp body is set at the end of the horizontal lamp holder away from the lifting tube.

[0035] When the horizontal lamp holder is connected to the lifting tube, a mounting hole is opened on the bottom surface of the horizontal lamp holder, and a limit column is provided at the top end of the lifting tube. The limit column is inserted into the horizontal lamp holder and fixed by a threaded fixing ring to ensure the stability of the assembly. The limit column is an external thread structure, which facilitates the passage of the wires of the second light strip.

[0036] In this embodiment, a first light bar 7 is fixed to the bottom surface of the horizontal lamp holder; a limiting plate 8 is fixed to the bottom end of the lifting tube, and the limiting plate is provided with a sleeve hole whose shape matches the cross-sectional shape of the hollow profile tube, and a plurality of step limiting grooves 9 are provided on the side of the lifting tube away from the hollow profile tube; wherein the limiting plate can be integrally formed with the lifting tube, or can be a splicing structure fixed by screws, which is mainly used to be sleeved on the hollow profile tube for lifting and lowering guidance, and at the same time prevent tilting or displacement after the lifting tube is limited, and Cooperate with the limiting clamp for two-point support to ensure the smooth and reliable lifting. The top edge of the step limiting groove can be a horizontal edge, the top edge of the step limiting groove can also be an inclined edge that is inclined upward from the opening to the inner side, and the top edge of the step limiting groove can also be an inclined edge that is inclined downward at a small angle from the opening to the inner side. The inclination angle of the small outward inclination can be 5-15 degrees. It is mainly used to position the limiting clamp through the top edge of the step limiting groove when the limiting clamp is clamped in, ensuring that the position of the limiting clamp in the step limiting groove is stable and reliable.

[0037] In this embodiment, the top of the hollow profile tube is rotatably connected to a limit clamp 11 via a pin 10. This limit clamp is a metal structural component that is primarily used to engage the step limit groove during the lifting of the lifting tube to achieve positioning, ensuring stable and reliable lifting position. During use, the lifting tube is raised and lowered on the outer side of the hollow profile tube. The limit plate is raised and lowered on the hollow profile and cooperates with the limit clamp to engage with different step limit grooves to achieve two-point positioning.

[0038] In this embodiment, a second light bar 12 is fixed to the inner wall of the lift tube, emitting light outward through the step-limiting groove. A third light bar 13 is provided on the outer wall of the hollow profile tube. This allows for lighting needs in various locations, expanding its applicability and meeting illumination requirements in diverse situations. In practical applications, it can be controlled using various control switches or remote controls.

[0039] In this embodiment, a limit pin 14 is fixed to the middle of the outer wall of the hollow profile tube. The limit piece is located between the limit pin and the base, and when the lifting tube rises, the limit piece abuts against the bottom surface of the limit pin to limit the lifting height. The limit pin limits the lifting tube's ascent, preventing the limit piece from detaching from the top of the hollow profile tube, ensuring smooth and reliable operation.

[0040] In this embodiment, a driving power source 15 is also provided. This driving power source is connected to the lamp body, the first light bar, and the second light bar via a spiral wire 16. The spiral wire is located within the hollow profile tube and is connected to the third light bar via a wire. The use of the spiral wire ensures effective power supply during lifting and lowering.

[0041] In this embodiment, a counterweight 17 is fixed within the base. The inner bottom wall of the hollow profile tube is provided with internal threads 18; an externally threaded post 19 is fixed to the top surface of the base. The bottom end of the hollow profile tube is secured to the base via the externally threaded post and internally threaded connection. This structure facilitates the assembly and connection of the base and the hollow profile tube.

[0042] In this embodiment, a diffuser plate 20 is vertically installed within the lift tube; it is located between the second light bar and the step limit groove. This improves the effectiveness of the second light bar. In this embodiment, the second light bar and diffuser plate are inserted from the top or bottom of the lift tube during assembly, ensuring smooth and reliable operation.

[0043] In this embodiment, a non-slip velvet layer 21 is fixed to the bottom surface of the base, which can improve the anti-slip performance.

[0044] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the end of the horizontal lamp holder is connected to the lamp body through a universal joint; the first light bar is fixed to the bottom surface of the horizontal lamp holder, and the outer side surface of the hollow profile tube is provided with a lifting tube, a limiting clamp, a step limiting groove and a limiting piece. The lifting tube is lifted and lowered on the outside of the hollow profile tube, and is limited on the hollow profile tube by the limiting piece, and the limiting clamp is clamped in the step limiting groove for limiting, thereby ensuring the stability and reliability of lifting and lowering, and the lamp body can adjust the illumination angle to meet the illumination needs of different situations, with convenient adjustment and strong applicability.

[0045] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here.
