Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-6A height-adjustable lighting fixture includes a lighting head 1, a connecting seat 2 on the top of the lighting head 1, a first movable post 3 vertically mounted on the top of the connecting seat 2, a second movable post 4 vertically inserted into the first movable post 3, an mounting head 5 on the top of the second movable post 4, a stud 41 on the bottom of one side surface of the second movable post 4, a limiting plate 6 mounted on the stud 41, a fixing component 7 screwed onto the stud 41 on one side of the limiting plate 6, a plug 62 on one side surface of the limiting plate 6, a through hole 61 above the plug 62 on the limiting plate 6, the diameter of the through hole 61 being larger than the large diameter of the stud 41, and the plug 62 being used to lock the first movable post 3 and the second movable post 4.

[0021] In addition, a first insert plate 32 and a second insert plate 33 are respectively provided on both sides of the first movable column 3. A first cavity 31 is vertically opened on the first movable column 3. Multiple first insertion holes 331 are evenly arranged on the second insert plate 33 along the vertical direction. The first insertion holes 331 are used for the insertion rod 62 to pass through. The first insertion holes 331 enable the first movable column 3 to be locked even when it extends to different lengths.

[0022] Furthermore, a second cavity 42 is vertically opened through the second movable column 4. A first insertion cavity 43 for the movement of the first insertion plate 32 is opened on one side of the second cavity 42, and a second insertion cavity 44 for the movement of the second insertion plate 33 is opened on the other side of the second cavity 42. A second insertion hole 45 is horizontally opened through the bottom of the second insertion cavity 44 of the second movable column 4. The second insertion hole 45 is used for the insertion rod 62 to pass through.

[0023] Meanwhile, a first wiring hole 21 is vertically opened in the middle of the connecting seat 2. The first wiring hole 21 is connected to the first cavity 31, and the first wiring hole 21 facilitates the passage of the connecting wire.

[0024] In addition, the mounting head 5 is provided with a second wiring hole 51, which facilitates the passage of connecting wires.

[0025] In this embodiment, when it is necessary to adjust the height of the bottom lighting head 1, the extension distance of the first movable column 3 can be changed, and the connecting wire is pre-lengthened and stored in the first cavity 31, so that the movement of the first movable column 3 will not cause the connecting wire to be too short. When adjusting the height, loosen the fixing part 7 so that the limiting plate 6 can be moved, so that the plug 62 can be pulled out from the first socket 331 and the second socket 45. At this time, the first movable column 3 in the second cavity 42 can be adjusted to adjust its extension length, thereby achieving the purpose of adjusting the height. After adjustment, align the first socket 331 with the second socket 331. Then, pass the plug 62 back through the first socket 331 and the second socket 45 to fix the first movable column 3 and prevent it from falling. The first plug plate 32 and the second plug plate 33 are provided to prevent the first movable column 3 from rotating.

[0026] In this invention, by loosening the fixing component 7, pulling out the insert 62, and then pulling out the first movable column 3, the height of the lighting lamp can be quickly adjusted. The first movable column 3 and the second movable column 4 enable the lighting lamp to have a height adjustment function. This nested movable column height adjustment method has a simple structure, convenient adjustment method, and facilitates wiring.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
