Technical Field

[0001] This utility model relates to the field of solar lighting technology, specifically to an LED solar lamp with a solar panel that can be suspended at any angle. Background Technology

[0002] LED solar lights have a wide range of applications, including outdoor lighting, landscape lighting, and rural lighting.

Landscape lighting, for example, is used to illuminate lakes, fountains, sculptures, and other scenic elements in parks, enhancing the artistic effect and nighttime aesthetics of the landscape. Rural lighting can solve the problem of inconvenient nighttime travel in rural areas and improve the quality of life for rural residents.

[0003] However, most current LED solar lights are not convenient enough in terms of adjusting the direction of light transmission from the solar panel and the direction of illumination of the LED lights, and need further improvement. Utility Model Content

[0009] And a spherical adjustment mechanism for connecting the main support rod and the ring adjustment mechanism.

[0052] Example 2:

[0053] Based on Example 1, such as Figure 5 As shown, the main support rod 11 is connected to the adjusting rotating disk 212 through a spherical adjustment mechanism 24.

[0054] The main support rod 11 is fixedly connected to the inner spherical shell 242.

[0055] like Figure 5 , Figure 6As shown, each spherical fixed constraint post 244 is driven to move by the second steel wire cable mechanism 25. The main support rod 11 has a second cable handle fixing groove 250 with internal and external communication on the side wall. The second steel wire cable mechanism 25 includes a second cable handle 251 connected to the second cable handle fixing groove 250 by a second fixed hinge 2501. A second cable drive swing arm 252 is fixed on the outside of the second cable handle 251. The second cable drive swing arm 252 drives the spherical fixed constraint post 244 to move through a second steel wire 253.

[0056] A second cable fixing seat 2502 is fixed inside the main support rod 11, a second cable connecting seat 2503 is fixed inside the constrained inner spherical shell 242, the end of the spherical fixed receiving cylinder 243 has a steel wire through hole 2504, the fixing anchor of one end of the second steel wire 253 is fixedly connected to the second cable fixing seat 2502, and the steel wire of one end of the second steel wire 253 is fixedly connected to the second cable drive swing arm 252;

[0057] The fixed anchor at the other end of the second steel wire 253 is fixedly connected to the second cable connector 2503, and the steel wire at the other end of the second steel wire 253 is fixedly connected to each spherical fixed constraint column 244.

[0058] It should be noted that the solar photovoltaic panel 12, LED lamp 13, battery 14, photovoltaic panel fixing hinge 122, lamp fixing hinge 131, first fixing hinge 2301, second fixing hinge 2501, first steel wire pull wire 233, and second steel wire pull wire 253 used in this application are all based on existing technology and are not specifically limited here. Those skilled in the art can choose according to their needs, as long as the technical solution of this application can be achieved.

[0059] In practical applications, the connecting seat fixing plate 101 facilitates fixing the entire device to the wall or support rod, and the connecting seat fixing plate 101 is fixed and installed by bolts through the fixing mounting holes 102.

[0060] By utilizing the ring adjustment mechanism 21 and the spherical adjustment mechanism 24, the solar photovoltaic panel 12 can rotate around the axis of the photovoltaic panel fixing hinge 122, and the LED lamp 13 can rotate around the axis of the lamp fixing hinge 131, which facilitates the adjustment of the light-giving direction of the solar photovoltaic panel 12 and the illumination direction of the LED lamp 13.

[0061] The specific adjustment method of the annular adjustment mechanism 21 is as follows: Manually pinch the first cable handle 231 to rotate it around the axis of the first fixed hinge 2301. The first cable handle 231, through the first cable drive swing arm 232, pulls the steel wire of the first steel wire pull line 233. The other end of the steel wire of the first steel wire pull line 233 will drive the release drive disc 222 to rotate. Under the constraint between the drive constraint groove 2220 and the pull rod constraint mating post 2230, the pull rod constraint mating post 2230, through the release drive pull rod 223, drives the circumferential locking post 213 to move, thus locking the position ratchet. 2131 moves away from the ratchet locking groove 2110. After the position locking ratchet 2131 disengages from the ratchet locking groove 2110, the main support rod 11 is turned to make the adjusting rotating disk 212 rotate around the axis of the adjusting fixing ring 211, thereby adjusting the direction of the main support rod 11. When it is rotated to the desired position, the first cable handle 231 is released, and the drive disk 222 is released to rotate in the opposite direction under the drive of the torsion spring, so that the position locking ratchet 2131 re-engages with the ratchet locking groove 2110, thus fixing and constraining the relative position between the adjusting rotating disk 212 and the adjusting fixing ring 211.

[0062] The specific adjustment method of the spherical adjustment mechanism 24 is as follows: manually squeeze the second cable handle 251 to rotate the second cable handle 251 around the pivot of the second fixed hinge 2501. The second cable handle 251 drives the swing arm 252 through the second cable to pull the steel wire of the second steel wire 253. The other end of the steel wire of the second steel wire 253 will drive each spherical fixed constraint post 244 to move synchronously, so that each spherical fixed constraint post 244 moves away from the inner wall of the constraint outer spherical shell 241, and each spherical fixed constraint post 244 and the constraint After the inner wall of the outer spherical shell 241 is disengaged, the main support rod 11 is turned to allow the inner spherical shell 242 to rotate freely around the center of the outer spherical shell 241, thereby adjusting the direction of the main support rod 11. When the desired position is reached, the second cable handle 251 is released. Driven by the spherical constraint support spring 2440, each spherical fixed constraint column 244 presses against the inner wall of the outer spherical shell 241 again. Static friction is used to maintain the relative position between the inner spherical shell 242 and the outer spherical shell 241.

[0063] After adjustment using the ring adjustment mechanism 21 and the spherical adjustment mechanism 24, manually rotate the solar photovoltaic panel 12 around the axis of the photovoltaic panel fixing hinge 122, and manually rotate the LED lamp 13 around the axis of the lamp fixing hinge 131 to fine-tune the light-giving direction of the solar photovoltaic panel 12 and the illumination direction of the LED lamp 13.
