[0031] The following specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the utility model, they are protected by the patent law.

[0032] The present scheme is realized through the following technical means:

[0033] Embodiment: In the embodiment, a buried LED lamp group convenient to replace and maintain is given. Through the split structure layout, the normal light emitting and lighting work is not affected, and great convenience is provided for the installation, construction, replacement and maintenance of the operating personnel, and the influence of replacement and maintenance on the surrounding ground layout can be reduced.

[0034] Specifically, the structure layout of the buried LED lamp group can refer to the structure layout of the buried LED lamp group shown in the accompanying drawings. Figure 1As shown, it mainly comprises a fixedly arranged embedded base 1 below the ground, the bottom of the embedded base 1 leads out a power supply line for supplying power to the lamp group, and a downwardly recessed mounting cavity 101 is formed in the embedded base 1, and a detachable lamp body 2 is arranged in the mounting cavity 101 in an upright state. The detachable lamp body 2 and the embedded base 1 form a screwing clamping structure 3 for realizing the connection and fixation of the two components and a self-adapting lap joint structure 4 for realizing the circuit conduction.

[0035] Referring to the drawings Figure 1 and 2 As shown, the screwing clamping structure 3 comprises a guide groove 301 formed in the inner side of the embedded base 1 and a pair of clamping guide columns 302 formed on the outer peripheral part of the detachable lamp body 2, and the guide groove 301 comprises two parts of a vertical section 3011 and an arc-shaped section 3012 connected with each other. When connecting and installing, first, the clamping guide columns 302 are placed into the vertical section 3011 of the guide groove 301 from top to bottom, and then the detachable lamp body 2 is rotated around the vertical center axis, so that the clamping guide columns 302 continue to move along the downwardly extending arc-shaped section 3012, until the complete clamping and fixation of the two components are realized. At this time, due to the existence of the self-adapting lap joint structure 4 formed between the detachable lamp body 2 and the embedded base 1, stable power supply to the detachable lamp body 2 can be ensured, so that the lighting effect is realized. For example, the self-adapting lap joint structure can be described with reference to the partially enlarged structure diagram given in the drawings Figure 1 and Figure 6 First, the self-adapting lap joint structure 4 comprises a lap joint column 401 arranged at the bottom of the mounting cavity 101 and a lap joint coil 402 arranged at the bottom of the detachable lamp body 2. When the detachable lamp body 2 is gradually installed into the embedded base 1, the contact fixation of the lap joint column 401 and the lap joint coil 402 can be completed, so that the power transmission of the embedded base 1 to the detachable lamp body 2 is realized, and the normal lighting work is ensured.

[0036] Further, the inventor also considers that after a certain period of use and work processing or repeated disassembly and assembly processing, the lap joint column 401 and the lap joint coil 402 will be deformed to a certain extent and become irreversible, so that after the detachable lamp body 2 is installed into the embedded base 1, a broken circuit also occurs, which cannot ensure stable power supply to the lighting unit. Therefore, in the embodiment, a liftable conduction mechanism 5 is designed between the lap joint column 401 and the embedded base 1. For details, please refer to the drawings Figure 6As shown in the structure, the liftable conducting mechanism 5 comprises a conducting plate 501 for fixedly mounting the overlapping column 401, a supporting spring 502 arranged between the conducting plate 501 and the inner bottom surface of the pre-embedded base 1, and a conducting connecting column 503 fixed on the pre-embedded base 1 and penetrating through the conducting plate 501. Under this structure, when the detachable lamp body 2 is installed into the pre-embedded base 1, the overlapping coil 402 at the bottom of the detachable lamp body 2 will first generate a downward extrusion force on the overlapping column 401, so that the conducting plate 501 moves downward along the conducting connecting column 503; and when the detachable lamp body 2 needs to be disassembled and replaced, the conducting connecting column 503 will no longer be extruded and will rise upward. Under this structure, the elastic lifting movement of the conducting plate 501 and the overlapping column 401 is realized, the plastic deformation of the components is reduced, and the conducting connection between the overlapping column 401 and the internal power supply circuit of the pre-embedded base 1 is maintained.

[0037] Considering the gap between the pre-embedded base 1 and the detachable lamp body 2, water vapor will enter the lamp group from the gap after a certain period of use, causing internal components to be corroded or even damaged and unable to work normally. Therefore, as a preferred structure, an annular supporting portion 201 for abutting against the upper surface of the pre-embedded base 1 is formed at the upper portion of the detachable lamp body 2, the radial dimension of the annular supporting portion 201 is greater than the opening size of the cavity in the pre-embedded base 1, so that the detachable lamp body 2 can be erected above the pre-embedded base 1. Meanwhile, an elastic sealing gasket 6 made of rubber is arranged between the ground of the annular supporting portion 201 and the upper surface of the pre-embedded base 1. As the detachable lamp body 2 is gradually connected and fixed, the upper edge of the pre-embedded base 1 and the lower surface of the annular supporting portion 201 will gradually extrude the elastic sealing gasket 6 therebetween, so as to make the internal space of the detachable lamp body 2 be in a relatively sealed state, avoiding damage to the internal circuit unit caused by water immersion.

[0038] Further, in order to realize smooth overlapping and conducting and connection and fixation of the self-adapting overlapping structure 4 when the detachable lamp body 2 is placed into the pre-embedded base 1, a tapered surface 1011 with a large upper portion and a small lower portion is formed at the lower inner side of the mounting cavity 101. Under this structure, when the detachable lamp body 2 is gradually placed into the pre-embedded base 1 from top to bottom, the bottom outer edge of the detachable lamp body 2 will gradually move downward in abutment with the inner wall of the tapered surface 1011, so as to avoid deviation of the two components during installation and connection and fixation, and ensure the stability and reliability of the connection.

[0039] In addition, a common situation is that such LED buried lamps are installed on the outer edges of road green belts or the edges of river embankments. Due to the green shrubs or fences, it is inconvenient for the operators to install the buried lamps, resulting in low efficiency of replacing and maintaining the detachable lamp body 2.

[0040] In view of the above problems, the embodiment of the present application further optimizes the above-mentioned buried LED lamp group convenient to replace and maintain. A downwardly recessed annular mounting groove 202 is arranged on the top outer side of the detachable lamp body 2. A upwardly flipable semi-annular lifting handle 7 is movably installed in the annular mounting groove 202. An upwardly recessed rotating positioning clamping notch 701 is arranged on the bottom of the center segment of the semi-annular lifting handle 7. Even if the operator is located at a certain distance from the lamp group, the front hook part of the hook device with a cantilever can be smoothly inserted into the notch and the semi-annular lifting handle 7 can be flipped up by lifting upwardly, so that the detachable lamp body 2 can be conveniently disassembled and assembled, and the work efficiency is greatly improved. Figure 5 Further preferably, referring to the partial enlarged structural schematic view shown in the accompanying drawings, the both sides of the rotating positioning clamping notch 701 can be arranged as inwardly recessed structure, so that the hook part for flipping and lifting the semi-annular lifting handle 7 can be more conveniently clamped and fixed and smoothly flipped and rotated.

[0041] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
