DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] See attached Figure 1-6 : In this embodiment, an aluminum tube with adjustable internal space includes a ring 1 and a cylinder 2. The ring 1 is slidably connected to the outer wall of the cylinder 2. The cylinder 2 slides inside the ring 1. The outer wall of the ring 1 is provided with an adjustment mechanism 3. The adjustment mechanism 3 adjusts the position of the cylinder 2 in the ring 1, and then adjusts the position of the mounting disc 403. A mounting mechanism 4 is provided below the cylinder 2. The mounting disc 403 in the mounting mechanism 4 can be replaced, which is not convenient for installing lamps of different models. The upper end of the cylinder 2 is fixedly connected to a limiting disc 5. The limiting disc 5 prevents the cylinder 2 from separating from the ring 1 during the downward movement, and plays a role in limiting the movement range of the cylinder 2.

[0022] Three support bars 6 are fixedly connected to the outer wall of the ring 1. The outer walls of the ends of the support bars 6 are clearance-matched with the grooves 7. The ends of the support bars 6 can be inserted into the grooves 7. The grooves 7 are arranged inside the arc blocks 8. The arc blocks 8 are fixed to the inner walls of the lamp aluminum tubes 9. The interiors of the lamp aluminum tubes 9 and the arc blocks 8 are both provided with through holes 11. The through holes 11 are clearance-matched with the outer walls of the second screw rod 10. The nut position of the second screw rod 10 cannot pass through the through holes 11. The outer walls of the second screw rod 10 are threadedly connected to the support bars 6. The second screw rod 10 positions the support bars 6 inside the grooves 7.

[0023] The adjusting mechanism 3 includes a sleeve 301, a slide bar 302, a slider 303, a spring 304 and a pull ring 305. The sleeve 301 is fixedly connected to the outer wall of the ring 1. The inner part of the sleeve 301 is slidably connected to the slide bar 302 and the slider 303. The slide bar 302 and the slider 303 slide inside the sleeve 301. The outer wall of the slide bar 302 is slidably connected to the ring 1. The slider 303 is fixedly connected to the outer wall of the slide bar 302. The slide bar 302 drives the slider 303 to slide. One end of the slide bar 302 is clamped with a groove provided in the cylinder 2. The slide bar 302 cooperates with the groove provided in the cylinder 2 to clamp and fix the cylinder 2 inside the ring 1.

[0024] The outer wall of the slide bar 302 is sleeved with a spring 304. The model of the spring 304 is selected according to the actual use requirements and can meet the work requirements. The two ends of the spring 304 are respectively fixedly connected to the sleeve 301 and the slide block 303. The spring 304 can drive the slide block 303 to slide under the elastic action. The other end of the slide bar 302 is fixedly connected with a pull ring 305, and the pull ring 305 drives the slide bar 302 to slide.

[0025] The pull ring 305 drives the slide bar 302 to slide, and the slide bar 302 drives the slider 303 to move. At the same time, the end of the slide bar 302 is separated from the slot set in the cylinder 2, and the slider 303 compresses the spring 304 and slides the cylinder 2, so that the position of the cylinder 2 inside the ring 2 changes, and then the height of the mounting disc 403 changes. After the mounting disc 403 is adjusted to the required height, the pull rings 305 on both sides are released, and the spring 304 drives the slider 303 to move in the opposite direction under the elastic action, and the slider 303 drives the slide bar 302 to move, and the end of the slide bar 302 is inserted into the slot set in the cylinder 2 to fix the cylinder 2 inside the ring 1, completing the adjustment of the height of the mounting disc 403, and then in actual use, it is convenient to adjust the height of the mounting disc 403 according to actual use requirements.

[0026] The mounting mechanism 4 includes a first screw rod 401, a support plate 402 and a mounting disc 403. The outer wall of the first screw rod 401 is threadedly connected to the cylinder 2. The first screw rod 401 and the cylinder 2 can be separated. The lower end of the first screw rod 401 is fixedly connected to the support plate 402. The first screw rod 401 and the support plate 402 move together. The lower part of the support plate 402 is fixedly connected to the mounting disc 403 by screws. The support plate 402 and the mounting disc 403 can be separated. The mounting disc 403 facilitates the installation of the lamp.

[0027] When the mounting disc 403 needs to be replaced, the mounting disc 403 is rotated, and the mounting disc 403 drives the support plate 402 to move, and the support plate 402 drives the first screw 401 to rotate, and the first screw 401 is separated from the cylinder 2, and the support plate 402, the mounting disc 403 and the first screw 401 are removed, and the support plate 402 is separated from the mounting disc 403, and the required mounting disc 403 is replaced, and the support plate 402 is fixed to the upper surface of the mounting disc 403 with screws, and the first screw 401 is screwed into the interior of the cylinder 2, and then the positions of the support plate 402 and the mounting disc 403 are fixed. In actual use, it is convenient to replace the mounting disc 403 of the required size according to actual use requirements.

[0028] Working principle:

[0029] When installing the lamp on the aluminum tube with adjustable internal space, insert the end of the support bar 6 into the inside of the groove 7, pass the second screw 10 through the through hole 11 and use a socket wrench to rotate the second screw 10, so that the end of the second screw 10 is screwed into the inside of the support bar 6, fix the support bar 6 in the inside of the groove 7, fix the position of the support bar 6, and then fix the position of the ring 1;

[0030] Installation disc replacement phase:

[0031] According to actual use requirements, when the installation disc 403 needs to be replaced, the installation disc 403 is rotated, the installation disc 403 drives the support plate 402 to move, the support plate 402 drives the first screw 401 to rotate, the first screw 401 is separated from the cylinder 2, the support plate 402, the installation disc 403 and the first screw 401 are removed, the support plate 402 is separated from the installation disc 403, and the required installation disc 403 is replaced, the support plate 402 is fixed to the upper surface of the installation disc 403 with screws, the first screw 401 is screwed into the inside of the cylinder 2, and then the positions of the support plate 402 and the installation disc 403 are fixed. In actual use, it is convenient to replace the installation disc 403 of the required size according to actual use requirements;

[0032] Height adjustment stages for mounting discs:

[0033] When the height of the mounting disc 403 needs to be adjusted according to actual use requirements, the pull rings 305 on both sides are pulled, and the pull rings 305 drive the slide bar 302 to slide, and the slide bar 302 drives the slider 303 to move. At the same time, the end of the slide bar 302 is separated from the slot set in the cylinder 2, and the slider 303 compresses the spring 304 and slides the cylinder 2, so that the position of the cylinder 2 inside the ring 2 changes, thereby changing the height of the mounting disc 403. After the mounting disc 403 is adjusted to the required height, the pull rings 305 on both sides are released. 5. The spring 304 drives the slider 303 to move in the opposite direction under the elastic action, and the slider 303 drives the slide bar 302 to move. The end of the slide bar 302 is inserted into the groove set in the cylinder 2 to fix the cylinder 2 inside the ring 1, and the height adjustment of the mounting disc 403 is completed. In actual use, it is convenient to adjust the height of the mounting disc 403 according to actual use requirements, and the lamp is installed on the mounting disc 403. The position of the mounting disc 403 can be adjusted, thereby realizing an aluminum tube with adjustable internal space.
