[0033] This embodiment provides a technical solution:

[0034] See also Figure 1-Figure 7 As shown, a wall-mounted underground lighting device comprises a lamp body 1, a connecting seat 10 is fixed to the rear end face of the lamp body 1, and connecting shafts 11 are fixed to the rear sides of the left and right ends of the connecting seat 10; a connecting portion 2 is provided at the rear side of the lamp body 1, and the connecting portion 2 comprises a connecting plate 20, and two positioning grooves 200 are provided on the rear end face of the connecting plate 20, and two ear plates 21 with a hollow structure are fixed to the front end face of the connecting plate 20, and the connecting shaft 11 passes through the ear plate 21 and is rotatably connected to the ear plate 21, and a worm gear 22 is rotatably installed in the inner cavity of the ear plate 21 located on the right side, and the connecting shaft 11 located on the right side is coaxially keyed with the worm gear 22, and a worm 23 is meshed with the rear side of the worm gear 22;

[0035] A mounting portion 3 is provided on the rear side of the connecting portion 2, and the mounting portion 3 includes a mounting plate 30, and a mounting groove 300 is provided on the front end surface of the mounting plate 30, and the connecting plate 20 is located in the mounting groove 300, and two positioning bars 304 are fixed in the mounting groove 300, and the positioning bars 304 are plugged into the positioning groove 200; the rear end surface of the mounting plate 30 is provided with grooves 301 at both left and right ends, and a slide plate 31 is installed in the groove 301, and a threaded rod 32 is rotatably installed at both left and right ends of the mounting plate 30, one end of the threaded rod 32 penetrates into the groove 301 and is rotatably connected to the slide plate 31, and the end of the threaded rod 32 extends from the outer side wall of the groove 301 and is threadedly connected thereto; two opposite end surfaces of the two slide plates 31 are fixed with two clamping blocks 34, and the clamping blocks 34 penetrate into the mounting groove 300 and are tightly pressed against both sides of the front end surface of the connecting plate 20.

[0036] In this embodiment, two positioning rods 303 are fixed to the installation groove 300, and two positioning holes 201 are provided at the connecting plate 20, and the positioning rods 303 are plugged into the positioning holes 201. The arrangement of the positioning rods 303 and the positioning holes 201 ensures accurate alignment and a stable connection between the connecting plate 20 and the installation groove 300.

[0037] In this embodiment, the four corners of the mounting plate 30 are fixed with protrusions 35, and the protrusions 35 are provided with mounting holes 350. The mounting holes 350 facilitate the use of bolts or other fasteners, and facilitate the installation of the protrusions 35 and the device on the well wall.

[0038] In this embodiment, the connection base 10 and the connection shaft 11 are an integrally formed structure, and the connection base 10 is fixedly connected to the lamp body 1 by bolts. The integrally formed connection base 10 and the connection shaft 11 have better connection strength, ensuring the connection stability and reliability of the connection base 10 and the connection shaft 11, and the bolt fixing method ensures the installation reliability between the connection base 10 and the lamp body 1.

[0039] In this embodiment, the two ends of the two threaded rods 32 that are separated from each other are coaxially keyed to an adjusting knob 33, and a plurality of anti-skid grooves are provided on the outer wall of the adjusting knob 33. The adjusting knob 33 makes the rotation of the threaded rod 32 more convenient, and the anti-skid grooves increase the user's hand feel during operation and prevent the problem of hand slipping.

[0040] In this embodiment, the bottom end of the worm 23 passes through the outer wall of the ear plate 21 and is rotatably connected thereto, and the bottom end of the worm 23 is coaxially keyed with an adjustment head 24. This design allows the user to conveniently rotate the worm 23 by rotating the adjustment head 24.

[0041] In this embodiment, the upper and lower side walls of the groove 301 are fixed with limit strips 302, and the upper and lower walls of the slide plate 31 are provided with limit slots, and the limit strips 302 are slidably connected with the corresponding limit slots. This design ensures that the slide plate 31 slides smoothly in the groove 301, prevents the slide plate 31 from deflecting or shaking during the sliding process, and improves the stability and reliability of the structure.

[0042] In this embodiment, the overall shape of the mounting groove 300 is rectangular, and the size of the mounting groove 300 is adapted to the size of the connecting plate 20. This design ensures that the connecting plate 20 can be fully and tightly embedded in the mounting groove 300, thereby improving the stability of the connection.

[0043] In this embodiment, the slide plate 31 and the block 34 are integrally formed, and both the slide plate 31 and the block 34 are made of stainless steel. This design improves the overall strength and durability of the slide plate 31 and the block 34, and ensures the limiting effect of the block 34 on the connecting plate 20. The stainless steel material has the advantage of corrosion resistance, which ensures the service life of the slide plate 31 and the block 34.

[0044] In this embodiment, the cross-section of the slide plate 31 is rectangular, and the size of the groove 301 matches the size of the slide plate 31. This design ensures smooth sliding of the slide plate 31 in the groove 301, and improves the flexibility and reliability of the structure.

[0045] It should be added that the outer wall of the adjusting head 24 in this embodiment is provided with a plurality of anti-slip edges. The provision of the anti-slip edges can increase the friction between the hand and the adjusting head 24, thereby making it difficult to slip when rotating the adjusting head 24, thereby improving the stability of the operation.

[0046] When adjusting the angle of the lamp body 1, the user first rotates the adjusting head 24, and the adjusting head 24 drives the worm 23 to rotate. Since the worm 23 is meshed with the worm wheel 22, the worm wheel 22 rotates and drives the connecting shaft 11 and the connecting seat 10 to rotate, and the connecting seat 10 drives the lamp body 1 to rotate. As the lamp body 1 rotates, the angle of the lamp body 1 is adjusted. When the lamp body 1 rotates to a suitable angle, the adjusting head 24 stops rotating.

[0047] When the lamp body 1 needs to be disassembled, the user first turns the adjustment knobs 33 on both sides to drive the threaded rod 32 to rotate. Since the threaded rod 32 and the outer wall of the groove 301 are threadedly connected, the rotation of the threaded rod 32 will synchronously produce linear displacement, thereby driving the slide plate 31 to move to one side. The slide plate 31 also drives the block 34 to move to one side, and the block 34 gradually disengages from the installation groove 300. When the block 34 disengages from the installation groove 300, the user pulls the connecting plate 20 to the front side, and the connecting plate 20 and the lamp body 1 are disassembled.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
