[0002] In the lighting field, traditional lighting fixtures have revealed numerous problems that urgently need to be addressed in practical use. These problems limit the efficiency, convenience, and applicability of lighting equipment. First, the height adjustment function of traditional lighting fixtures is significantly inadequate. Many existing fixtures use single-pole vertical supports, the height of which is often fixed, or the adjustment method is complex and requires the use of various tools. In different scenarios, such as meeting rooms where the lighting height needs to be adjusted according to the meeting setup, or exhibition halls where the angle and height of the light beam need to be flexibly changed to highlight exhibits, traditional fixtures cannot quickly and conveniently achieve height adjustment, failing to meet diverse lighting needs.

[0003] Secondly, traditional light fixtures present significant difficulties in replacing light fixtures. Due to their unreasonable structural design, operators often need to work at heights or use complex auxiliary tools to disassemble and install the fixtures. This not only increases the difficulty of operation but also introduces higher safety risks. Furthermore, the wiring methods of traditional light fixtures are inadequate. Some light fixtures lack internal hollow wiring designs, resulting in exposed wiring that not only affects aesthetics but is also susceptible to interference and damage from external factors, increasing maintenance costs and safety hazards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-5 The lighting fixture shown includes a base plate 1 and a metal fixing sleeve 2 welded to the outer wall of the top of the base plate 1. A stable lifting and adjusting bracket 4 is inserted into the metal fixing sleeve 2. The bottom end of the stable lifting and adjusting bracket 4 is fixedly connected to the metal fixing sleeve 2 by welding. A hollow top bracket 5 is provided at the top of the stable lifting and adjusting bracket 4, extending horizontally to the right. A lamp holder 6 is provided at the right end of the hollow top bracket 5, and a lamp shade 7 is provided at the bottom end of the lamp holder 6. This lighting fixture aims to construct a stable and easy-to-operate lighting equipment support system. The base plate 1 serves as the basic support component of the entire fixture, providing a stable installation platform for subsequent components. The metal fixing sleeve is welded to the outer wall of the top of the base plate 1. 2. A reliable insertion and fixing position is provided for the stable lifting and adjusting bracket 4, ensuring the stability of the overall structure of the lamp holder. An internal threaded bulb interface 9 is provided at the center of the bottom of the lamp holder 6. An illumination bulb 8 is provided at the bottom of the internal threaded bulb interface 9. An external threaded connector is provided at the top of the illumination bulb 8, and the external threaded connector is threaded into the internal threaded bulb interface 9. The lamp cover 7 is located outside the illumination bulb 8. The threaded connection method has the characteristics of firm installation and convenient disassembly. Users can easily unscrew or screw on the illumination bulb 8 to achieve the purpose of quick lamp replacement. The lamp cover 7 is located outside the illumination bulb 8, mainly to protect the illumination bulb 8 and reasonably diffuse the light, improve the lighting effect and extend the bulb's service life.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a battery 3 is installed at the top of the base plate 1. The battery 3 has a power socket inside its front end. The purpose of the battery 3 is to provide power to the lighting bulb 8, enabling the lamp holder to have independent power supply capabilities, free from the limitations of external power socket locations, thus increasing its flexibility. The power socket inside the front end of the battery 3 can be used to charge the battery 3, ensuring its continuous power supply capability. In some cases, it can also serve as an external power interface to directly power the lighting bulb 8 or other related equipment, expanding the lamp holder's power supply options. An anti-slip pad made of soft rubber is also attached to the outer wall of the bottom of the base plate 1. When the lamp holder is placed on the ground, the anti-slip pad increases friction with the ground, effectively preventing the lamp holder from sliding or tipping over due to external forces during use, ensuring stable placement of the lamp holder, and thus ensuring normal lighting operation.

[0024] like Figure 1 , Figure 4 and Figure 5As shown, the stable lifting and adjusting bracket 4 includes a bottom hollow bracket 10, an internally threaded lifting and adjusting cylinder 14, a top hollow bracket 17, a hollow lifting threaded cylinder A18, and a hollow lifting threaded cylinder B19. The bottom hollow bracket 10 is inserted into the metal fixing sleeve 2 at its bottom end, and the bottom hollow bracket 10 and the metal fixing sleeve 2 are fixedly connected by welding. The top of the bottom hollow bracket 10 is welded with the hollow lifting threaded cylinder A18, and the hollow lifting threaded cylinder B19 is arranged above the hollow lifting threaded cylinder A18. The top of the hollow lifting threaded cylinder B19 is welded with a top hollow... Support 17, hollow top frame 5 is set at the top of the hollow support 17. Hollow lifting threaded cylinder A18 and hollow lifting threaded cylinder B19 are externally threaded and connected to an internally threaded lifting adjusting cylinder 14. The sum of the lengths of hollow lifting threaded cylinders A18 and B19 is equal to the length of the internally threaded lifting adjusting cylinder 14. Clockwise rotation of the internally threaded lifting adjusting cylinder 14 can push hollow lifting threaded cylinder A18 downward and hollow lifting threaded cylinder B19 upward through the thread action. Counterclockwise rotation of the internally threaded lifting adjusting cylinder 14 can push hollow lifting threaded cylinder A18 downward and hollow lifting threaded cylinder B19 upward through the thread action. The core of the stable lifting and adjusting bracket 4 is to achieve flexible adjustment of the lamp holder height by pushing the hollow lifting threaded cylinder A18 upward and the hollow lifting threaded cylinder B19 downward respectively. The bottom hollow bracket 10 serves as the basic support part of the entire bracket and is firmly welded to the metal fixing sleeve 2 to provide stable support for subsequent components. The hollow lifting threaded cylinders A18 and B are respectively welded to the top of the bottom hollow bracket 10 and the bottom of the top hollow bracket 17. The internal thread lifting adjusting cylinder 14 is threaded onto their outside. When the internal thread lifting adjusting cylinder 14 is pushed clockwise... When the needle rotates, based on the principle of thread transmission, it will push the hollow lifting threaded cylinder A18 downward and the hollow lifting threaded cylinder B19 upward respectively, thereby raising the top hollow support 17 and driving the entire lamp holder to rise. Conversely, when the internal thread lifting adjustment cylinder 14 rotates counterclockwise, it will push the hollow lifting threaded cylinder A18 upward and the hollow lifting threaded cylinder B19 downward respectively, causing the top hollow support 17 to fall and lowering the lamp holder height. This design allows the lamp holder to be conveniently and quickly adjusted to a suitable height according to actual usage needs.

[0025] like Figure 1 , Figure 4 and Figure 5As shown, the stable lifting and adjusting bracket 4 also includes a metal fixing ring A11, an L-shaped stabilizing bar A12, a lifting limiting cylinder 13, an L-shaped stabilizing bar B15, and a metal fixing ring B16. The bottom hollow bracket 10 has a metal fixing ring A11 externally sleeved and fixed at its top, and the top hollow bracket 17 has a metal fixing ring B16 externally sleeved and fixed at its bottom. The metal fixing rings A11 and B16 are located at the bottom and top of the internally threaded lifting and adjusting cylinder 14, respectively. An L-shaped stabilizing bar A15 is welded to the left end of the metal fixing ring A11. 2. An L-shaped stabilizer bar B15 is welded to the left end of the metal fixing ring B16. The vertical section of the L-shaped stabilizer bar A12 is located below the vertical section of the L-shaped stabilizer bar B15. A lifting limiting cylinder 13 is sleeved around the vertical sections of the L-shaped stabilizer bar A12 and B15. When the hollow lifting threaded cylinders A18 and B19 move up and down, they can respectively drive the L-shaped stabilizer bars A12 and B15 to move up and down synchronously. Both the L-shaped stabilizer bars A12 and B15 can... The lifting limiting cylinder 13 moves up and down internally. This structural design effectively restricts the movement direction of the hollow lifting threaded cylinders A18 and B, ensuring their vertical stability during height adjustment and preventing swaying or displacement from affecting the stability of the entire bracket. When the top of the hollow lifting threaded cylinder A18 is in contact with the bottom of the hollow lifting threaded cylinder B19, the top of the L-shaped stabilizing rod A12 will simultaneously be in contact with the bottom of the L-shaped stabilizing rod B15. The lifting limiting cylinder 13 can be used as a portable handle. When the top of the lifting threaded cylinder A is in contact with the bottom of the lifting threaded cylinder B, the top of the L-shaped stabilizing rod A12 will simultaneously be in contact with the bottom of the L-shaped stabilizing rod B15. At this time, the position of the lifting limiting cylinder 13 is convenient for the user to hold. When moving or transporting the lamp holder, the user can directly hold the lifting limiting cylinder 13, making it a portable handle. This ingenious design not only facilitates the movement and transport of the lamp holder but also utilizes existing structural components, eliminating the need for additional complex handle devices, simplifying the lamp holder structure and reducing costs.
