[0006] Furthermore, the number of support plates is four, and the four support plates are symmetrically arranged with the lampshade as the center. The number of casters is four, and the four casters are all located at the bottom of the base.

[0007] Furthermore, the mounting mechanism includes a lamp holder, a reset telescopic rod is fixedly connected inside the lamp holder, a force-bearing ring is fixedly connected to the inner wall of the reset telescopic rod away from the lamp holder, a curved plate is fixedly connected to the surface of the mounting plate, and a contact ring is fixedly connected to the end of the curved plate away from the mounting plate.

[0008] Furthermore, the top of the lamp holder is provided with a sliding hole, the end of the fixing rod is rotatably connected to the inner wall of the lamp holder, the end of the fixing rod away from the driven frame is rotatably connected to the surface of the force ring, and the number of fixing rings is set to four, which are symmetrically arranged with the sliding hole as the center.

[0009] Furthermore, the fixing mechanism includes a sliding column, a right-angle rod is fixedly connected to the end of the sliding column, a force-bearing spring is fixedly connected to the surface of the right-angle rod, a driven pull plate is fixedly connected to the end of the sliding column away from the right-angle rod, a pull rod is rotatably connected to the outer wall of the driven pull plate, a sliding plate is rotatably connected to the end of the pull rod away from the driven pull plate, and a sliding groove plate is fixedly connected to the top of the lamp holder.

[0010] Furthermore, the outer wall of the sliding column contacts the inner wall of the sliding hole, the end of the force-bearing spring away from the right-angle rod is fixedly connected to the top of the inner wall of the lamp holder, the surface of the sliding plate is slidably connected to the inner wall of the sliding groove plate, the end of the limiting spring away from the driven rod is fixedly connected to the outer wall of the lamp holder, the end of the driven rod away from the reinforcing ring is fixedly connected to the end of the sliding plate, and the end of the right-angle rod away from the sliding column is fixedly connected to the surface of the force-bearing ring.

[0011] Furthermore, the limiting mechanism includes a grooved plate, a column is fixedly connected to the surface of the grooved plate, a slip ring is slidably connected to the surface of the column, a passive rod is rotatably connected to the surface of the slip ring, a telescopic elastic rod is fixedly connected to the end of the slide, and a curved rod is fixedly connected to the bottom of the grooved plate.

[0012] Furthermore, the end of the column away from the grooved plate is fixedly connected to the top of the inner wall of the support plate, the surface of the slide is slidably connected to the inner wall of the grooved plate, the end of the passive rod away from the slip ring is rotatably connected to the surface of the slide, the end of the curved rod away from the bottom of the grooved plate is fixedly connected to the surface of the lamp holder, four inclined rings are provided, the four inclined rings are symmetrically arranged with the column as the center, and the end of the telescopic elastic rod away from the slide is fixedly connected to the inner wall of the grooved plate.

[0013] The present invention has the following beneficial effects: This invention utilizes an installation mechanism. First, the worker lifts the installation plate and moves it upwards. As the plate moves, it moves the lampshade and the light fixture upwards. Simultaneously, it moves the installation column and the bent plate upwards. The bent plate then pushes the contact ring upwards. During this movement, the contact ring contacts the bottom of the force ring, pushing it upwards. The force ring's movement then retracts the reset telescopic rod upwards. Simultaneously, the force ring compresses the fixing rod, causing its ends to move closer together. This movement pushes the driven frame closer together, which in turn pushes the fixing ring closer together. At this point, the top of the installation column moves to the same height as the top of the fixing ring. As the fixing ring moves, it contacts the surface of the installation column, fixing it in place. This achieves rapid installation of the entire light fixture, eliminating cumbersome steps and improving efficiency.

[0014] This invention employs a fixing mechanism. When the force ring moves upward, it pushes the right-angle rod upward. As the right-angle rod moves, it compresses the force spring, causing the spring to contract upward. When the force spring reaches its limit, it restricts the right-angle rod, preventing contact between the rod and the inner wall of the lamp holder. Simultaneously, the upward movement of the right-angle rod drives the sliding column upward. This movement pushes the driven pull plate upward, which in turn pulls the pull rod closer together. The movement of the pull rod then pulls the sliding plate... The inner walls of the sliding plates slide towards each other. When the sliding plate slides, it drives the driven rod to move towards each other. When the driven rod moves, it compresses the limit spring. When the limit spring is compressed, it contracts towards each other. When it contracts to the end, it limits the driven rod, thus preventing the driven rod from contacting the outer wall of the lamp holder. When the driven rod moves, it pushes the reinforcing ring towards each other. When the reinforcing ring moves, it contacts the outer wall of the mounting plate, thus reinforcing the mounting plate and making the lighting lamp more stable during use.

[0015] This invention employs a limiting mechanism. When the driven pull plate moves upward, it compresses the inclined ring. When the inclined ring is compressed, it moves away from the driven ring. This movement pushes the bent rod towards the driven ring, which in turn moves the bent rod towards the driven ring. The bent rod's movement causes the slide to slide away from the driven ring on the inner wall of the grooved plate. As the slide slides, it compresses the telescopic elastic rod, which retracts away from the driven ring. When the telescopic elastic rod retracts to its final position, it limits the slide, preventing contact between the slide and the inner wall of the grooved plate. Simultaneously, the slide moves the driven rod away from the driven ring, which pulls the sliding ring downward on the surface of the column. When the movable pull plate moves above the inclined ring, the inclined ring no longer exerts pressure. At this point, the elastic force of the telescopic elastic rod will cause the carriage to move the bent rod and the inclined ring back to their original positions. When the carriage returns to its original positions, it will also cause the driven rod and the slip ring to return to their original positions. Since the upper surface of the inclined ring is flat, it can limit the driven pull plate, thereby limiting the fixing mechanism and the installation mechanism as a whole. It also allows for the quick installation and fixing of the lighting fixture. When it is necessary to disassemble the lighting fixture, the slip ring can be pushed down to slide, causing the driven rod to push the carriage to move away from each other. The carriage will then cause the bent rod and the inclined ring to move away from each other, allowing the driven pull plate to return to its original positions. This enables the quick disassembly and limiting of the lighting fixture.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-11 As shown, the present invention is an LED light source assembly for low-level lighting, including a base 1, a support plate 2 fixedly connected to the surface of the base 1, a caster wheel 3 fixedly connected to the bottom of the base 1, a mounting plate 4 provided above the base 1, a lampshade 5 fixedly connected to the bottom of the mounting plate 4, a mounting post 6 fixedly connected to the surface of the mounting plate 4, and a lighting lamp 7 fixedly connected to the bottom of the mounting plate 4, and also includes; The mounting mechanism 10 includes a fixed rod 14. When the force ring 13 moves, it will squeeze the fixed rod 14. When the fixed rod 14 is squeezed, the end of the fixed rod 14 will move towards each other. The end of the fixed rod 14 is rotatably connected to a driven frame 15. When the fixed rod 14 moves, it will push the driven frame 15 towards each other. A fixed ring 16 is fixedly connected to the surface of the driven frame 15. When the driven frame 15 moves, it will push the fixed ring 16 towards each other. At this time, the top of the mounting column 6 moves to the same height as the top of the fixed ring 16. When the fixed ring 16 moves, it will contact the surface of the mounting column 6 and fix the mounting column 6. The fixing mechanism 30 includes a driven rod 37. When the slide plate 36 slides, it drives the driven rod 37 to move closer to each other. A reinforcing ring 38 is fixedly connected to the end of the driven rod 37. A limit spring 39 is fixedly connected to the surface of the driven rod 37. When the driven rod 37 moves, it compresses the limit spring 39. When the limit spring 39 is compressed, it contracts in the direction of closer to each other. When it contracts to the end, it limits the driven rod 37, thereby preventing the driven rod 37 from contacting the outer wall of the lamp holder 11. When the driven rod 37 moves, it pushes the reinforcing ring 38 to move closer to each other. When the reinforcing ring 38 moves, it contacts the outer wall of the mounting plate 4, thereby reinforcing the mounting plate 4 and making the lighting lamp 7 more stable during use. The limiting mechanism 50 includes a slide 55. When the bent rod 57 moves, it will drive the slide 55 to slide away from each other on the inner wall of the grooved plate 51. The bottom of the slide 55 is fixedly connected to the bent rod 57. When the inclined ring 58 moves, it will push the bent rod 57 to move closer to each other. The end of the bent rod 57 away from the slide 55 is fixedly connected to the inclined ring 58. When the driven pull plate 34 moves upward, it will squeeze the inclined ring 58. When the inclined ring 58 is squeezed, it will move away from each other.

[0022] There are four support plates 2, which are symmetrically arranged with the lampshade 5 as the center. There are also four casters 3, which are all located at the bottom of the base 1.

[0023] The mounting mechanism 10 includes a lamp holder 11, with a reset telescopic rod 12 fixedly connected inside the lamp holder 11. When the force ring 13 moves, it pushes the reset telescopic rod 12 to retract upward. The force ring 13 is fixedly connected to the inner wall of the reset telescopic rod 12 away from the lamp holder 11. A curved plate 17 is fixedly connected to the surface of the mounting plate 4. First, the worker picks up the mounting plate 4 and moves it upward. When the mounting plate 4 moves, it drives the lamp cover 5 and the lighting lamp 7 to move upward. At the same time, the mounting column 6 and the curved plate 17 move upward. A contact ring 18 is fixedly connected to the end of the curved plate 17 away from the mounting plate 4. When the curved plate 17 moves, it pushes the contact ring 18 to move upward, thereby achieving a quick installation of the entire lighting lamp 7, saving tedious steps and improving efficiency.

[0024] The top of the lamp holder 11 has a sliding hole. The end of the fixing rod 14 is rotatably connected to the inner wall of the lamp holder 11. The end of the fixing rod 14 away from the driven frame 15 is rotatably connected to the surface of the force ring 13 and pushes the force ring 13 to move upward. When the contact ring 18 moves, it will contact the bottom of the force ring 13. There are four fixing rings 16, which are symmetrically arranged with the sliding hole as the center.

[0025] The fixing mechanism 30 includes a sliding column 31, with a right-angle rod 32 fixedly connected to its end. When the force ring 13 moves upward, it pushes the right-angle rod 32 upward. A force spring 33 is fixedly connected to the surface of the right-angle rod 32. When the right-angle rod 32 moves, it compresses the force spring 33. When the force spring 33 is compressed, it contracts upward. When the force spring 33 reaches its position, it limits the right-angle rod 32, thus preventing the right-angle rod 32 from contacting the inner wall of the lamp holder 11. A driven pull plate 34 is fixedly connected to the end away from the right-angle rod 32. When the sliding column 31 moves, it will push the driven pull plate 34 to move upward. A pull rod 35 is rotatably connected to the outer wall of the driven pull plate 34. When the driven pull plate 34 moves, it will pull the pull rod 35 to move in a direction closer to each other. A sliding plate 36 is rotatably connected to the end of the pull rod 35 away from the driven pull plate 34. When the pull rod 35 moves, it will pull the sliding plate 36 to slide in a direction closer to each other on the inner wall of the slide plate 40. The top of the lamp holder 11 is fixedly connected to the slide plate 40.

[0026] The outer wall of the sliding column 31 contacts the inner wall of the sliding hole. When the right-angle rod 32 moves upward, it will drive the sliding column 31 to move upward. The end of the force spring 33 away from the right-angle rod 32 is fixedly connected to the top of the inner wall of the lamp holder 11. The surface of the slide plate 36 is slidably connected to the inner wall of the slide plate 40. The end of the limit spring 39 away from the driven rod 37 is fixedly connected to the outer wall of the lamp holder 11. The end of the driven rod 37 away from the reinforcing ring 38 is fixedly connected to the end of the slide plate 36. The end of the right-angle rod 32 away from the sliding column 31 is fixedly connected to the surface of the force ring 13.

[0027] The limiting mechanism 50 includes a grooved plate 51, a column 52 fixedly connected to the surface of the grooved plate 51, and a slip ring 53 slidably connected to the surface of the column 52. When the lighting lamp 7 needs to be disassembled, the slip ring 53 can be pushed to slide downwards. A passive rod 54 is rotatably connected to the surface of the slip ring 53. A telescopic elastic rod 56 is fixedly connected to the end of the slide 55, so that the passive rod 54 pushes the slide 55 to move away from each other. The slide 55 will drive the four-bend rod 57 and the inclined ring 58 to move away from each other, which can reset the driven pull plate 34, thereby achieving quick disassembly and limiting of the lighting lamp 7. When the slide 55 slides, it will squeeze the telescopic elastic rod 56. When the telescopic elastic rod 56 is squeezed, it will retract in the away direction. When the telescopic elastic rod 56 retracts to the end, it will limit the slide 55, thereby preventing the slide 55 from contacting the inner wall of the grooved plate 51. A curved rod 59 is fixedly connected to the bottom of the grooved plate 51.

[0028] The end of the column 52 furthest from the grooved plate 51 is fixedly connected to the top of the inner wall of the support plate 2. When the passive rod 54 moves, it pulls the slip ring 53 to slide downward on the surface of the column 52. The surface of the slide 55 is slidably connected to the inner wall of the grooved plate 51. The end of the passive rod 54 furthest from the slip ring 53 is rotatably connected to the surface of the slide 55. When the slide 55 slides, it drives the passive rod 54 to move in a direction away from each other. The end of the curved rod 59 furthest from the bottom of the grooved plate 51 is fixedly connected to the surface of the lamp holder 11. Four inclined rings 58 are provided, and the four inclined rings 58 are symmetrically arranged with the column 52 as the center. When the movable pull plate 34 moves above the inclined ring 58, the inclined ring 58 no longer exerts pressure. At this time, the elastic force of the telescopic elastic rod 56 will cause the slide 55 to drive the bent rod 57 and the inclined ring 58 to return to their original positions. When the slide 55 returns to its original position, it will drive the passive rod 54 and the slip ring 53 to return to their original positions. Since the upper surface of the inclined ring 58 is flat, it can limit the driven pull plate 34, limit the fixing mechanism 30 and the installation mechanism 10 as a whole, and allow the lighting lamp 7 to be quickly installed and fixed. The end of the telescopic elastic rod 56 away from the slide 55 is fixedly connected to the inner wall of the groove plate 51.

[0029] In use, the operator first lifts the mounting plate 4 and moves it upwards. As the mounting plate 4 moves, it causes the lampshade 5 and the lighting lamp 7 to move upwards. Simultaneously, the mounting plate 4 moves the mounting column 6 and the bent plate 17 upwards. The bent plate 17 then pushes the contact ring 18 upwards. During this movement, the contact ring 18 contacts the bottom of the force ring 13, pushing it upwards. The force ring 13 then pushes the reset telescopic rod 12 upwards. Simultaneously, the force ring 13 compresses the fixing rod 14. This compression causes the ends of the fixing rod 14 to move closer together. This movement of the fixing rod 14 then pushes the driven frame 15 to move closer together. When the driven frame 15 moves, it pushes the fixing ring 16 to move closer to each other. At this time, the top of the mounting post 6 moves to the same height as the top of the fixing ring 16. As the fixing ring 16 moves, it contacts the surface of the mounting post 6 and fixes the mounting post 6, thereby achieving quick installation of the entire lighting lamp 7, saving tedious steps and improving efficiency. When the force ring 13 moves upward, it pushes the right-angle rod 32 upward. When the right-angle rod 32 moves, it compresses the force spring 33. When the force spring 33 is compressed, it contracts upward. When the force spring 33 reaches its position, it limits the right-angle rod 32, thereby preventing the right-angle rod 32 from contacting the inner wall of the lamp holder 11. When the right-angle rod 32 moves upward, it compresses the force spring 33. When the sliding column 31 moves upward, it pushes the driven pull plate 34 upward. When the driven pull plate 34 moves, it pulls the pull rod 35 towards the same direction. When the pull rod 35 moves, it pulls the slide plate 36 to slide towards the same direction on the inner wall of the slide plate 40. When the slide plate 36 slides, it drives the driven rod 37 towards the same direction. When the driven rod 37 moves, it compresses the limiting spring 39. When the limiting spring 39 is compressed, it contracts towards the same direction. When it contracts to the correct position, it limits the driven rod 37, thus preventing the driven rod 37 from contacting the outer wall of the lamp holder 11. When the driven rod 37 moves, it pushes the reinforcing ring 38 towards the same direction. When the fixed ring 38 moves, it contacts the outer wall of the mounting plate 4, thereby reinforcing the mounting plate 4 and making the lighting lamp 7 more stable during use. As the driven pull plate 34 moves upward, it compresses the inclined ring 58. When the inclined ring 58 is compressed, it moves away from the object. This movement pushes the bent rod 57 towards the object. The bent rod 57 then moves the slide 55 along the inner wall of the grooved plate 51, causing it to slide away from the object. As the slide 55 slides, it compresses the telescopic elastic rod 56. When the telescopic elastic rod 56 is compressed, it retracts away from the object. When the telescopic elastic rod 56 retracts to its final position, it limits the movement of the slide 55, preventing it from contacting the inner wall of the grooved plate 51.As the carriage 55 slides, it drives the driven rod 54 to move away from each other. When the driven rod 54 moves, it pulls the slip ring 53 downwards on the surface of the column 52. When the driven pull plate 34 moves above the inclined ring 58, the inclined ring 58 no longer has compressive force. At this point, the elastic force of the telescopic elastic rod 56 causes the carriage 55 to return the bent rod 57 and the inclined ring 58 to their original positions. As the carriage 55 returns to its original position, it also drives the driven rod 54 and the slip ring 53 to their original positions. Because the upper surface of the inclined ring 58... The planar surface allows for limiting the driven pull plate 34, thus limiting the overall positioning of the fixing mechanism 30 and the mounting mechanism 10. This enables quick installation and fixing of the lighting lamp 7. When disassembly of the lighting lamp 7 is required, the slip ring 53 can be pushed downwards, causing the driven rod 54 to push the slide 55 in a direction away from each other. The slide 55 then drives the four-bend rod 57 and the inclined ring 58 in the same direction, allowing the driven pull plate 34 to reset. This achieves both quick disassembly and limiting of the lighting lamp 7.
