DETAILED DESCRIPTION

[0019] See also Figure 1-4 The utility model provides an energy-saving LED lamp, including an LED lamp body 1, a U-shaped connecting frame 2 is arranged at one end of the LED lamp body 1, movable shafts 4 are rotatably connected to the inner surface of the connecting frame 2 on both sides, and the two movable shafts 4 are rotatably connected to the surface of the LED lamp body 1 on the side close to each other, and a gear 5 is fixedly sleeved on the outer circumference of the movable shaft 4, and a rack 6 is meshed with the top of the gear 5. A U-shaped connecting plate 9 is fixed on the top of the two racks 6, and a connecting seat 3 is fixed on the surface of the top of the connecting frame 2, and a rod groove is provided on the surface of the connecting seat 3 close to one end of the connecting plate 9 10. Two symmetrically distributed threaded sleeves 12 are slidably inserted inside the rod groove 10. One end of the threaded sleeve 12 is hinged with a connecting rod 13. One end of the connecting rod 13 is hinged to the surface of the connecting plate 9. By changing the spacing between the two threaded sleeves 12, the connecting rod 13 can change its angle, so that the connecting plate 9 can drive the rack 6 to engage, so that the movable shaft 4 can drive the LED lamp body 1 to change its angle, so that the irradiation range of the LED lamp body 1 can be adjusted according to actual usage, thereby improving the applicability of the device.

[0020] Further Figure 1 and Figure 2 As shown, it is worth explaining in detail that a first threaded rod 11 is threadedly connected through the middle position of the two threaded sleeves 12, one end of the first threaded rod 11 is rotatably connected to the inner surface of the rod groove 10, and the other end of the first threaded rod 11 passes through the connecting seat 3 and extends to one side of the connecting seat 3. By rotating the first threaded rod 11 to make it rotate, the inner cavity of the rod groove 10 can play a role of resisting and limiting the threaded sleeve 12, and the external thread structures on both sides of the outer circumference of the first threaded rod 11 are set in opposite directions, so that the threaded sleeves 12 can change the spacing between them under the cooperation between the internal thread structure of the inner wall of the threaded sleeve 12 and the external thread structure of the outer circumference of the first threaded rod 11.

[0021] Further Figure 4As shown, it is worth explaining in detail that a limiting groove 7 is provided on the inner surface of the connecting frame 2 near the position of the adjacent position rack 6, and a limiting block 8 is slidably inserted inside the limiting groove 7. The side of the two limiting blocks 8 close to each other passes through the adjacent position limiting groove 7 and is fixed to the surface of the adjacent position rack 6. Since the limiting block 8 can only slide along the inner cavity trajectory of the adjacent position limiting groove 7, it can limit the movement trajectory of the rack 6 to ensure the meshing effect between the rack 6 and the adjacent position gear 5.

[0022] Further Figure 3 As shown, it is worth explaining in detail that limiting columns 14 are fixed at the four corners of the bottom surface of the connecting frame 2, and a limiting rod 15 is slidably inserted inside the limiting column 14. The bottom of the limiting rod 15 passes through the limiting column 14 at the adjacent position and extends to the bottom position of the limiting column 14. The four limiting rods 15 extend to the surface where the bottom position of the limiting column 14 is fixed with a supporting plate 16, and the surface of the top of one side of the support plate 16 is rotatably connected with a threaded cylinder 17, and a second threaded rod 18 is threadedly connected at the middle position of the threaded cylinder 17, and the top of the second threaded rod 18 passes through the threaded cylinder 17 and is fixed to the surface of the bottom of the connecting frame 2, and the threaded cylinder 17 is rotated so that the threaded cylinder 17 and the second threaded rod 18 are meshed, so that under the limiting effect of the limiting rod 15 and the limiting column 14 on the connecting frame 2, the second threaded rod 18 can drive the connecting frame 2 to move vertically upward, thereby increasing the irradiation height of the LED lamp body 1.

[0023] This solution has the following working process: in actual use, when the user needs to adjust the illumination angle of the LED lamp body 1 according to actual conditions, the first threaded rod 11 is rotated to make it rotate. Since the inner cavity of the rod groove 10 can play a role of resisting and limiting the threaded sleeve 12, and the external thread structures on both sides of the outer circumference of the first threaded rod 11 are arranged in opposite directions, the threaded sleeve 12 can change the spacing between the threaded sleeves 12 under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer circumference of the first threaded rod 11, so that the connecting rod 13 can change its angle, so that the connecting plate 9 can drive the two racks 6 to move in the horizontal direction, so that the racks 6 can mesh with the gear 5. The movable shaft 4 can rotate to a certain angle, so that the angle of the LED lamp body 1 can be deflected to a certain angle driven by the movable shaft 4, thereby realizing the adjustment of the irradiation angle of the LED lamp body 1, and due to the connection between the threaded sleeve 12 and the first threaded rod 11, it can ensure that the LED lamp body 1 can be in a stable state even at various angles to maintain the irradiation effect. When the irradiation height of the LED lamp body 1 needs to be adjusted, the threaded barrel 17 is rotated to allow the threaded barrel 17 and the second threaded rod 18 to engage with each other, so that the second threaded rod 18 can drive the connecting frame 2 to move vertically upward under the limiting effect of the limiting rod 15 and the limiting column 14 on the connecting frame 2, thereby increasing the irradiation height of the LED lamp body 1.

[0024] According to the above working process, it can be known that: by rotating the first threaded rod 11, the distance between the two threaded sleeves 12 can be changed, so that the angle of the connecting rod 13 can be changed, so that the connecting plate 9 can drive the rack 6 to mesh, so that the movable shaft 4 can drive the LED lamp body 1 to change its angle, so that the illumination range of the LED lamp body 1 can be adjusted according to actual usage. At the same time, the height of the connecting frame 2 and the LED lamp body 1 can be adjusted by rotating the threaded barrel 17, thereby further expanding the illumination range of the LED lamp body 1, thereby further improving the application range of the device, and because the connection between the threaded sleeve 12 and the first threaded rod 11 can ensure that the LED lamp body 1 can be in a stable state at various angles, thereby improving the practicality of the device.

[0025] Further Figure 4 As shown, it is worth explaining in detail that the inner cavity of the limit groove 7 is T-shaped, and the surface of the inner part of the limit block 8 embedded in the adjacent position limit groove 7 is T-shaped. Due to the shape setting of the inner cavity of the limit groove 7 and the limit block 8, the contact area between the inner cavity of the limit groove 7 and the limit block 8 can be increased, thereby improving the limiting effect of the limit block 8.

[0026] In summary: by rotating the first threaded rod 11, the spacing between the two threaded sleeves 12 can be changed, so that the angle of the connecting rod 13 can be changed, so that the connecting plate 9 can drive the rack 6 to mesh, so that the movable shaft 4 can drive the LED lamp body 1 to change its angle, so that the illumination range of the LED lamp body 1 can be adjusted according to actual usage. At the same time, by rotating the threaded cylinder 17, the height of the connecting frame 2 and the LED lamp body 1 can be adjusted, thereby further expanding the illumination range of the LED lamp body 1, thereby further improving the application scope of the device, and because the connection between the threaded sleeve 12 and the first threaded rod 11 can ensure that the LED lamp body 1 can be in a stable state at a variety of angles, thereby improving the practicality of the device, and due to the shape setting of the inner cavity of the limit groove 7 and the limit block 8, the contact area between the inner cavity of the limit groove 7 and the limit block 8 can be increased, thereby improving the limiting effect of the limit block 8.
