Description

Technical Field

[0001] The utility model relates to the technical field of underground lamps, in particular to an adjustable underground lamp. Background Art

[0002] Underground lights are lighting fixtures embedded in the ground. They illuminate the ground and aboveground vegetation, enhancing the landscape and ensuring pedestrian safety. They currently utilize energy-saving LED light sources, with polished stainless steel or aluminum alloy panels, high-quality waterproof connectors, silicone seals, and tempered glass, providing protection against water, dust, leakage, and corrosion. To ensure smooth drainage, it is recommended to place gravel under the lights during installation.

[0003] Prior art CN109578881 B discloses an LED underground lamp, in which the lamp body is supported by support rods and is enclosed and installed in a fixed groove. When the illumination direction of the lamp body needs to be adjusted, the staff only needs to move the permanent magnetic rod close to one of the support rods. Under the traction of the magnetic attraction, the support rod moves upward, and the other support rod connected to the support rod through the damping strip moves downward by the same amplitude. At this time, the lamp body will rotate a certain angle in this direction, but the angle adjustment is very inconvenient, and the stability is poor after the angle adjustment is completed.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-4As shown, the adjustable underground light of the present invention comprises a hollow outer shell 01 and a hollow inner shell 02 mounted within the outer shell 01. A light-emitting assembly 03 is housed within the inner shell 02. A mounting base 04 is fixedly attached to the outer surface of the inner shell 02. Mounting base 04 is provided with a drive disc 05 and a drive shaft 06, which are arranged perpendicularly to each other. A transmission rod 07, extending toward the center of the inner shell 02, is fixedly attached to one side of the drive disc 05. The light-emitting assembly 03 is in transmission connection with the transmission rod 07. A gear ring 08 is fixedly attached to the surface of the drive disc 05. A gear 09, meshing with the gear ring 08, is fixedly attached to one end of the drive shaft 06. The other end of the drive shaft 06 extends axially outside the inner shell 02. When the drive shaft 06 rotates, the gear 09 and gear ring 08 cooperate to drive the drive disc 05 to rotate within the mounting base 04. The rotation of the drive disc 05, in turn, drives the light-emitting assembly 03 within the inner shell 02, thereby adjusting the illumination angle of the reflective assembly.

[0022] When in use, the inner shell 02 is fixedly installed in the outer shell 01 and buried underground. When the illumination angle of the light-emitting component 03 needs to be adjusted, since the end of the drive shaft 06 extends beyond the inner shell, the operator only needs to stand on the bottom surface and use a tool to rotate the drive shaft 06 to adjust the illumination angle of the light-emitting component 03.

[0023] The mounting base 04 includes a base 10 integrally formed and fixedly connected to the inner shell 02 and a cover 11 fixedly mounted on the base 10 by fasteners.

[0024] A support base 12 and a fixing bracket 13 are fixedly connected to the cover plate 11. Both ends of the fixing bracket 13 are fixed to the cover plate 11 via fasteners. Both the support base 12 and the fixing bracket 13 are provided with arcuate grooves 14 that mate with the drive shaft 06. A support ring 15 is provided within the arcuate groove 14 on the fixing bracket 13. A support groove 16 that mates with the support ring 15 is provided on the outer surface of the drive shaft 06. Since the drive shaft 06 is vertically mounted on the outer surface of the inner shell 02, the cooperation between the support ring 15 and the support groove 16 prevents the drive shaft 06 from moving in one direction, allowing the drive shaft 06 to rotate freely.

[0025] The cover plate 11 is provided with a mounting hole 17 adapted for the drive disc 05. The bottom surface of the mounting hole 17 is provided with a fan-shaped limiting groove 18 recessed toward the center of the inner shell 02. A fan-shaped limiting plate 19 is fixedly connected to the drive disc 05. The limiting plate 19 and the gear ring 08 are located on either side of the drive disc 05. The drive disc 05 is mounted in the mounting hole 17, and the limiting plate 19 is located within the limiting groove 18. When the drive disc 05 rotates within the mounting hole 17, the limiting groove 18 and the limiting plate 19 cooperate to limit the rotation angle of the drive disc 05 within the mounting hole 17. Because the light-emitting assembly 03 is mounted in the inner shell 02, the provision of the limiting groove 18 and the limiting plate 19 ensures that the light energy generated by the light-emitting assembly 03 is entirely emitted from the top of the inner shell 02 when the illumination angle of the light-emitting assembly 03 is adjusted, which is equivalent to setting the maximum adjustment angle of the light-emitting assembly 03.

[0026] The base 10 is provided with a relief hole 20 coaxially arranged with the mounting hole 17. A support column 21 fixedly connected to the inner shell 02 is provided within the relief hole 20. A sealing hole 22 and a through hole 23 are coaxially provided on the support column 21. The through hole 23 is connected to the inner shell 02 and has a smaller diameter than the sealing hole 22. A sealing ring 24 is provided within the sealing hole 22, and a retaining ring 25 is threadedly connected to the opening of the sealing hole 22.

[0027] Lighting assembly 03 includes a heat sink 26 and a light source 27 mounted on top of the heat sink 26. Connecting shafts 28 and support shafts 29 are symmetrically positioned on either side of the heat sink 26. Support shafts 29 are mounted within inner housing 02 via bearing blocks. Connecting shaft 28 is positioned within sealing hole 22 through insertion hole 23 and connected to transmission rod 07. The aforementioned sealing ring 24 and retaining ring 25 are both mounted on connecting shaft 28. Rotating retaining ring 25 deforms sealing ring 24 within sealing hole 22, thereby sealing connecting shaft 28.

[0028] A drive slot 30 is provided at the end of the connecting shaft 28, and a drive block 31 is provided on the transmission rod 07 to fit within the drive slot 30. The drive block 31 is inserted into the drive slot 30. Through the cooperation between the drive slot 30 and the drive block 31, when the drive disk 05 rotates, the connecting shaft 28 is rotated, and the light-emitting assembly 03 is further rotated.

[0029] The bearing seat includes a support platform 32 disposed within the inner housing 02 and a retaining ring 33 fixed to the support platform 32 via fasteners. Both the retaining ring 33 and the support platform 32 are provided with a semicircular rotation groove 34 that mates with the support shaft 29. A semicircular retaining ring 35 is located within the rotation groove 34 of the retaining ring 33. The support shaft 29 is provided with an annular groove 36 that mates with the retaining ring 35. A blind hole is provided at the bottom of the rotation groove 34 of the support platform 32. The blind hole and the retaining ring 35 are located on either side of the support shaft 29. A spring 37 is disposed within the blind hole, one end of which abuts the bottom of the blind hole, and the other end of the spring 37 abuts the support shaft 29. The provision of the spring 37 ensures that the retaining ring 35 is always inserted within the annular groove 36.

[0030] The top of the outer shell 01 is provided with a mounting step. The inner shell 02 is fixed to the step of the outer shell 01 via fasteners and is flush with the top of the outer shell 01. The top of the inner shell 02 is provided with a light-transmitting plate 38 and a cover 39 that secures the light-transmitting plate 38. The diameter of the cover 39 is larger than that of the outer shell 01. The end of the drive shaft 06 passes through the cover 39 and is flush with it.

[0031] A sealing cover is installed at the bottom of the inner shell 02, and a waterproof connector is installed on the sealing cover. A bottom cover is set at the bottom of the outer shell 01. A through hole is set on the bottom cover.

[0032] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
