DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 6 A headlamp with an adjustment function comprises a first headband 1 and a second headband 2 which are arranged correspondingly, a lighting lamp 5 is arranged on the front side of the first headband 1, and the rear side of the lighting lamp 5 is fixedly connected to the front side of the first headband 1 through an adjustment mechanism:

[0023] Furthermore, the adjustment mechanism includes a mounting plate 7, to which a mounting frame 6 is fixedly connected on the left and right sides of the top of the mounting plate 7, the top of the mounting frame 6 is rotatably connected to the lighting lamp 5, a lifting sleeve 8 is fixedly connected to the top of the rear side of the mounting plate 7, a threaded rod 9 is threadedly connected to the center of the inner wall of the lifting sleeve 8, the bottom of the threaded rod 9 is rotatably connected to the top of the first headband 1, the top of the threaded rod 9 is rotatably connected to a fixing plate 10, the top center of the fixing plate 10 is fixedly connected to a first motor 11, and the output end of the first motor 11 is fixedly connected to the top of the threaded rod 9.

[0024] When the height of the lighting lamp 5 needs to be adjusted, the user can start the first motor 11, and the first motor 11 drives the threaded rod 9 to rotate at the top of the first headband 1. When the threaded rod 9 rotates, it drives the lifting sleeve 8 to rotate along its surface and drives the mounting plate 7 to move up and down along the surface of the threaded rod 9 through the cooperation of the limiting rod 12, so as to adjust the height of the lighting lamp 5 to the use height, which can meet the user's height adjustment requirements of the lighting lamp 5.

[0025] Furthermore, a plurality of slide bars 3 are slidably connected between one end of the first headband 1 and the second headband 2 , and a plurality of connecting bolts 4 are connected between the other ends of the first headband 1 and the second headband 2 .

[0026] A plurality of slide bars 3 are slidably connected between one end of the first headband 1 and the second headband 2, allowing the headlamp to be fine-tuned in head diameter to accommodate heads of different sizes. The slide bar 3 design ensures the stability of the first headband 1 and the second headband 2 during the extension and retraction process, and can be quickly adjusted according to actual needs, thereby improving comfort. The other ends of the first headband 1 and the second headband 2 are fixedly connected by a plurality of connecting bolts 4. This design ensures that the headlamp fits firmly on the user's head, preventing the headlamp from shaking or shifting due to vibrations generated during movement.

[0027] Furthermore, the lighting lamp 5 includes a lamp holder 501 , and a rotating shaft is fixedly connected to the left and right sides of the lamp holder 501 , and the rotating shaft is rotatably connected to the mounting frame 6 , and a plurality of LED lamps 502 are fixedly connected to the front side of the lamp holder 501 .

[0028] The design of multiple LED lights 502 can not only provide sufficient lighting brightness, but also achieve lighting effects of different intensities and ranges by lighting in combination or in groups, thereby meeting the lighting needs of users in different environments and conditions.

[0030] When the second motor 14 drives the rotating rod 13 and the second gear 15 thereon to rotate, the meshing action between the first gear 505 and the second gear 15 drives the fixing rod 504 and the lamp holder 501 to rotate together, so that the lamp holder 501 can rotate at an angle, thereby conveniently expanding the lighting range of the headlight.

[0031] Furthermore, the left and right sides of the bottom of the fixing plate 10 are fixedly connected with the limiting rod 12, the bottom of the limiting rod 12 is fixedly connected to the top of the first headband 1, and the limiting rod 12 is slidably connected to the lifting sleeve 8.

[0032] When the threaded rod 9 drives the lighting lamp 5 to adjust its vertical height, the limit rod 12 can facilitate the lifting sleeve 8 to slide up and down along its surface. On the one hand, it plays a guiding and supporting role to ensure that the lighting lamp 5 does not deviate from the track during the lifting process; on the other hand, it also limits the maximum rising and falling range of the lighting lamp 5 to avoid damage to the equipment due to excessive adjustment.

[0033] Furthermore, a rotating rod 13 is rotatably connected to the top of the mounting plate 7, one end of the rotating rod 13 extends to one side of the mounting plate 7 and is fixedly connected to a second motor 14, the second motor 14 is fixedly connected to one side of the mounting plate 7, and second gears 15 are fixedly connected to the left and right ends of the surface of the rotating rod 13, and the second gear 15 is meshed with the first gear 505.

[0034] When the user needs to adjust the lighting angle of the lighting lamp 5, the user can start the second motor 14, and the second motor 14 drives the rotating rod 13 to rotate on the top of the mounting plate 7. As the rotating rod 13 rotates, the second gear 15 is driven to rotate coaxially with the rotating rod 13. When the second gear 15 rotates, it drives the first gear 505 meshing with it to rotate. When the first gear 505 rotates, it can drive the fixing rod 504 and the connecting seat 503 to rotate coaxially and drive the entire lighting lamp 5 to rotate on the top of the mounting bracket 6 through the cooperation of the lamp holder 501 and the LED lamp 502. The lighting lamp 5 can rotate freely on the mounting bracket 6, thereby realizing the angle adjustment of the lighting lamp 5, which greatly facilitates the user to adjust the lighting direction according to actual needs. The operation is simple, the use is convenient, and the practicability is strong.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
