Slide grooves 13 are symmetrically arranged inside the left and right sides of the inner cylinder 8. Positioning components 9 are arranged on the inner sides of the two slide grooves 13. Fixed blocks 11 are symmetrically and fixedly connected to the outer wall of the inner cylinder 8. A protective edge ring 12 is fixedly sleeved on the outer side of the top of the inner cylinder 8.

[0028] On the basis of the above structure, a first sealing ring 2 is inlaid and connected to the outer edge of the top of the installation cylinder 1. A wire connection hole 3 is opened at the center of the bottom end of the installation cylinder 1. A second sealing ring 4 is arranged outside the wire connection hole 3. The second sealing ring 4 is inlaid on the inner bottom of the installation cylinder 1. Both the first sealing ring 2 and the second sealing ring 4 are made of rubber material.

[0029] In this embodiment, by providing the first sealing ring 2 and the second sealing ring 4, it is convenient to efficiently seal between the installation cylinder 1 and the protective edge ring 12, and between the installation cylinder 1 and the lamp cylinder 10, which can achieve a good waterproof effect and avoid the water inlet failure of the buried lamp.

[0030] On the basis of the above structure, the limiting clamping groove 7 includes a limiting groove 71 and an inclined surface 72. The limiting groove 71 includes a vertical section and a horizontal arc section at the bottom of the vertical section. An inclined surface 72 is provided at the junction of the horizontal arc section and the vertical section.

[0031] In this embodiment, by providing the inclined surface 72, when the fixed block 11 rotates with the inner cylinder 8, it can be subjected to a downward extrusion force, which is convenient for pressing the first sealing ring 2 and the second sealing ring 4, and the sealing effect is better.

[0032] On the basis of the above structure, the positioning component 9 includes a movable plate 91, a long bolt 92 and a support spring 93. The movable plate 91 is clamped and slidably located inside the slide groove 13. A long bolt 92 is movably installed inside the movable plate 91. Support springs 93 are fixedly connected between the bottom of the left and right sides of the movable plate 91 and the inner bottom of the slide groove 13.

[0033] In this embodiment, by providing the support spring 93, it is convenient to push the movable plate 91 upward. The top of the extended movable plate 91 can be used as a handle when the inner cylinder 8 is installed, which is convenient for controlling the rotation and adjustment of the inner cylinder 8 and is convenient for disassembly and assembly.

[0034] On the basis of the above structure, the bottom longitudinal section of the movable plate 91 is in an inverted "convex" shape structure. The bottom of the movable plate 91 is clamped inside the positioning groove 5, and the internal thread of the threaded hole 6 is adapted to the external thread at the bottom end of the long bolt 92.

[0035] In this embodiment, the long bolt 92 is used to facilitate the stable clamping of the bottom of the movable plate 91 inside the positioning groove 5, so as to be able to position the inner cylinder 8, avoid the automatic rotation of the inner cylinder 8, ensure that the fixed block 11 is stably clamped in the limiting groove 71, and ensure the stability of the installation of the buried lamp.

[0036] On the basis of the above structure, the two fixed blocks 11 respectively correspond to the two limiting card slots 7, and the fixed block 11 is clamped and connected with the installation cylinder 1 through the limiting card slot 7.

[0037] In this embodiment, the fixed block 11 is clamped and connected with the installation cylinder 1 through the limiting card slot 7, which can realize the preliminary positioning of the lamp cylinder 10.

[0038] The working principle of the present utility model is as follows:

[0039] During use, first align the two fixed blocks 11 with the two limiting card slots 7 respectively, and then insert the inner cylinder 8 into the installation cylinder 1 from top to bottom. When the two fixed blocks 11 are respectively inserted into the bottoms of the vertical sections of the two limiting grooves 71, the inner cylinder 8 can be rotated in the clockwise direction. At this time, as Figure 4 shown in the figure, the support spring 93 can be used to make the movable plate 91 in a raised state, and the top of the movable plate 91 extending from the inside of the inner cylinder 8 can be used as a handle to facilitate the control of the rotation of the inner cylinder 8 and is convenient for operation. The fixed block 11 can follow the rotation of the inner cylinder 8 and enter the horizontal arc section of the limiting groove 71, and the preliminary positioning of the inner cylinder 8 and the lamp cylinder 10 inside the installation cylinder 1 can be realized. And during the process of the fixed block 11 entering the horizontal arc section of the limiting groove 71, under the extrusion of the inclined surface 72, the fixed block 11 and the inner cylinder 8 can be subjected to a downward extrusion force when rotating, which is convenient for pressing the first sealing ring 2 and the second sealing ring 4, facilitating the efficient sealing between the installation cylinder 1 and the edge protection ring 12, as well as between the installation cylinder 1 and the lamp cylinder 10, and can achieve a good waterproof effect, avoid the water inlet failure of the buried lamp, and facilitate its long-term use;

[0040] After initially positioning the inner cylinder 8 and the lamp cylinder 10 inside the installation cylinder 1 by using the fixing block 11 and the limit card slot 7, at this time, the two positioning components 9 are exactly above the two positioning slots 5. Then, press the movable plate 91 downward so that the bottom of it is inserted into the positioning slot 5. Next, use tools such as a screwdriver to rotate the long rod bolt 92 so that the bottom of the long rod bolt 92 is threadedly connected to the inside of the threaded hole 6, and then the movable plate 91 can be positioned. By using the positioning slot 5, the movable plate 91 is engaged with the installation cylinder 1, and the inner cylinder 8 can be positioned to prevent the inner cylinder 8 from automatically rotating. The fixing block 11 can be stably engaged in the limit slot 71, ensuring the stable installation state of the buried lamp.

[0041] In summary, this buried lamp achieves the purpose of rapid disassembly and assembly by means of engagement. Compared with the prior art means such as the comparative document, the structure of this solution is simpler, the disassembly and assembly operation is faster, and when a failure occurs after long-term use, it is easier to disassemble, replace and repair.
