[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides an LED buried lamp with a lifting structure, including a housing 1. Guide blocks 23 are fixedly connected to the inner surfaces of the front and rear sides of the housing 1 near the right side. Guide columns 22 are slidably connected between the inner surfaces of the two guide blocks 23. A mounting plate 2 is fixedly connected between the tops of the two guide columns 22. An LED buried lamp body 21 is installed on the top of the mounting plate 2. Adjusting plates 3 are symmetrically and fixedly connected to the bottom of the mounting plate 2. A slide bar 4 is arranged between the outer surfaces of the two adjusting plates 3. Two groups of bottom grooves 31, inclined grooves 32 and high grooves 33 are formed on the outer surfaces of the adjusting plates 3. Two pressing rods 43 are fixedly connected to the front and rear outer surfaces of the slide bar 4. The bottom grooves 31, inclined grooves 32 and high grooves 33 are in communication. The pressing rods 43 are located between the inner surfaces of the high grooves 33. A slide rail 12 is fixedly connected between the inner surfaces of the two sides of the housing 1. A chute 41 is formed at the bottom of the slide bar 4. The inner surface of the chute 41 is slidably fitted with the outer surface of the slide rail 12. A top cover 11 is fixedly installed on the top of the housing 1. The outer surface of the mounting plate 2 slidably penetrates through the bottom of the top cover 11. An activity groove 13 is formed at the top of the top cover 11 near the left side. A pull rod 42 is fixedly connected to the top of the slide bar 4 near the left side. The outer surface of the pull rod 42 is slidably fitted with the inner surface of the activity groove 13. The top of the pull rod 42 is located above the top cover 11.

[0023] The effect achieved by the entire Embodiment 1 is that when using this device and adjusting the height of the LED buried lamp body 21, the pull rod 42 in the movable slot 13 above the top cover 11 can be operated. Since the pull rod 42 is fixedly connected to the slide bar 4, pulling the pull rod 42 will drive the slide bar 4 to move left and right on the adjusting plate 3. Since the outer surface of the adjusting plate 3 is designed with a bottom slot 31, an inclined slot 32, and a high slot 33, and these three groups of slots are interconnected, the slide bar 4 can move left and right on the adjusting plate 3. When maintenance is required, pull the pull rod 42 to the left. When the extrusion rod 43 is located in the bottom slot 31, the mounting plate 2 will be in the highest position. After the maintenance is completed, the extrusion rod 43 will move to the right under the action of the slide bar 4, passing through the position of the bottom slot 31, then moving to the position of the inclined slot 32 and then to the position of the high slot 33. At this time, the height of the LED buried lamp body 21 drops, so that the LED buried lamp body 21 is in a state of being buried in the ground. The entire design makes the maintenance operation simple, time-saving and labor-saving, thus greatly improving the efficiency of maintaining the LED buried lamp body 21. At the same time, the sliding groove 41 at the bottom of the slide bar 4 is slidably matched with the slide rails 12 on the inner surfaces of both sides of the housing 1, ensuring the stability and smoothness of the slide bar 4 during the movement process. In addition, the sliding connection between the guiding blocks 23 and the guiding columns 22 on the front and rear sides of the housing 1 also provides stable guidance for the lifting of the mounting plate 2.

[0024] Embodiment 2, as Figures 1 - 4 shown, the bottom end of the guiding column 22 is fixedly connected with a limiting ring 24, and the diameter of the limiting ring 24 is larger than the diameter of the guiding column 22.

[0025] The effect achieved by the entire Embodiment 2 is that the limiting ring 24 at the bottom end of the guiding column 22 is to prevent the guiding column 22 on the mounting plate 2 from falling off the guiding block 23 during the lifting movement, playing a further role in stabilizing the mounting plate 2.

[0026] Working principle: When it is necessary to adjust the height of the LED buried light body 21, the pull rod 42 in the movable slot 13 above the top cover 11 can be operated. Since the pull rod 42 is fixedly connected to the slide bar 4, pulling the pull rod 42 will drive the slide bar 4 to move left and right on the adjusting plate 3. Since the outer surface of the adjusting plate 3 is designed with a bottom groove 31, an inclined groove 32 and a high groove 33, and these three groups of grooves are interconnected, the slide bar 4 can move left and right on the adjusting plate 3. When maintenance is required, pull the pull rod 42 to the left. When the pressing rod 43 is located in the bottom groove 31, the mounting plate 2 will be in the highest position. After the maintenance is completed, the pressing rod 43 will move to the right under the action of the slide bar 4, and then move from the position of the bottom groove 31 to the position of the inclined groove 32 and then to the position of the high groove 33. At this time, the height of the LED buried light body 21 drops, so that the LED buried light body 21 is in a state of being buried in the ground. The whole design makes the maintenance operation simple, time-saving and labor-saving, thus greatly improving the efficiency of maintaining the LED buried light body 21. The limit ring 24 at the bottom end of the guide post 22 is to prevent the guide post 22 on the mounting plate 2 from falling off the guide block 23 during the up and down movement, improving the reliability of the device during use.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
