[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figures 1 to 8 This embodiment provides a two-way knob adjustment structure, including a light strip and a headlamp body 7. The headlamp body 7 is fixedly connected to the light strip, which is used to fix the headlamp body 7 to the head. It also includes an adjustment mechanism 9, which includes a knob 1, a bracket 2, and a rotating wheel 3. The bracket 2 is fixedly connected to the light strip, and the rotating wheel 3 is rotatably disposed inside the bracket 2. The knob 1 is fixedly disposed on the top of the bracket 2 and rotatably connected to the bracket 2. When the knob 1 is rotated clockwise, the light strip tightens; when the knob 1 is rotated counterclockwise, the light strip loosens.

[0030] The light strip includes a battery box 5, a headlamp strip 6, and a headlamp piece 8. The battery box 5 is fixedly installed on the outside of the headlamp strip 6. Both ends of the headlamp piece 8 are fixedly connected to both ends of the headlamp strip 6, so that the headlamp strip 6 and the headlamp piece 8 form a circle. The headlamp body 7 is fixedly installed on the outside of the headlamp piece 8. The headlamp piece 8 is made of sheet rubber, which is soft and elastic, comfortable to wear, and easy to adjust the size. The headlamp strip 6 is made of sheet rubber and is S-shaped, which makes it easy for the cord 4 to pass through.

[0031] The headlamp strip 6 has several through holes 61, and several ropes 4 are threaded through the holes 61.

[0032] The support portion 2 includes a limiting component and a support body 24. The limiting component includes a step 21, two through holes 22 and several crown teeth 23.

[0033] The support body 24 is a hollow column. The support body 24 is fixed on the outside of the battery box 5. The crown teeth 23 are all fixed on the inner ring of the top of the support body 24. The through holes 22 are all provided on both sides of the support body 24 to provide a channel for the rope 4. The step 21 is fixed on the outer ring of the support body 24.

[0034] The rotating part 3 includes a hollow cylinder 31, a number of elastic arms 32 and a number of square bone positions 33. The hollow cylinder 31 is located inside the support body 24 and is rotatably connected to the support body 24. The square bone positions 33 are all fixedly installed on the top of the hollow cylinder 31. The elastic arms 32 are all fixedly installed on the outer ring of the top of the hollow cylinder 31, and the elastic arms 32 are arranged opposite each other in pairs.

[0035] The hollow cylinder 31 has two through holes 311 on its side, which are used to provide a channel for the rope 4. The ends of the elastic arm 32 are all fixed with ratchet teeth 321, and the surface of the ratchet teeth 321 is inclined.

[0036] The knob part 1 includes several arc-shaped bone positions 11, several buckles 12 and a knob body 13. The knob body 13 is fixedly mounted on the top of the hollow cylinder 31 and is rotatably connected to the support body 24. The buckles 12 are all fixedly mounted on the bottom of the inner side wall of the knob body 13. The arc-shaped bone positions 11 are all fixedly mounted on the top of the inner side of the knob body 13. One side of the arc-shaped bone position 11 has a vertical surface 112 and the other side has an oblique angle 111.

[0037] Both ends of the battery box 5 are fixed with limiting holes for restricting the rope 4 to the two sides of the battery box 5.

[0038] The battery box 5 contains a battery for powering the headlamp body 7. The battery is connected to the headlamp body 7 via a wire. The wire is located inside the headlamp strip 6 and the headlamp plate 8 to prevent it from being damaged by the outside.

[0039] Fold one of the ropes 4 in half, and pass it through the small hole 61 alternately from the end away from the battery box 5, then through the limiting holes on both sides of the battery box 5. Then, thread both ends of the rope 4 through the through holes 22 on the bracket body 24, and finally through the wire hole 311 into the hollow cylinder 31. In the same way, pass the other rope 4 through the small hole 61 on the headlamp strip 6 on the other side of the battery box 5 into the hollow cylinder 31. Finally, tie the two ropes 4 together inside the hollow cylinder 31 to prevent the ropes 4 from coming out of the hollow cylinder 31 and losing their adjustment function.

[0040] When it is necessary to fix the headlamp body 7 on the head: Rotate the knob body 13 clockwise. The angle 111 of the arc-shaped bone position 11 on the knob body 13 will press the ratchet 321 clockwise downward until the ratchet 321 disengages from the crown tooth 23. At this time, there is no obstruction in the clockwise direction of the rotating wheel part 3. As the knob body 13 continues to rotate clockwise, the vertical surface 112 of the arc-shaped bone position 11 on the knob body 13 will push the square bone position 33 on the rotating wheel part 3, so that the rotating wheel part 3 also rotates clockwise and wraps the two ropes 4 around the hollow cylinder 31 of the rotating wheel part 3. The ropes 4 pull the headlamp strip 6, so that the part of the headlamp strip 6 that is threaded through the ropes 4 is folded in an S-shape, and the part that is not threaded through the ropes 4 is stretched elastically. Tighten the headlamp strip 6 to fix the product on the user's head.

[0041] When the headlamp body 7 needs to be removed from the head: rotate the knob body 13 counterclockwise. The angle 111 of the arc-shaped bone position 11 on the knob body 13 will press the ratchet 321 counterclockwise downward until the ratchet 321 disengages from the crown tooth 23. At this time, there is no obstruction in the counterclockwise direction of the rotating wheel part 3. As the knob body 13 continues to rotate counterclockwise, the vertical surface 112 of the arc-shaped bone position 11 on the knob body 13 will push the square bone position 33 on the rotating wheel part 3, so that the rotating wheel part 3 also rotates counterclockwise. This will loosen the two ropes 4 wrapped around the hollow cylinder 31 of the rotating wheel part 3, release the elasticity of the headlamp strap 6, and reduce the pressure of the headlamp strap 6 on the user's head.

[0042] When the user does not turn the knob body 13, since the ratchet 321 and the crown tooth 23 are engaged with each other and the ratchet directions are opposite, the wheel part 3 cannot be turned clockwise or counterclockwise, and the rope cannot be pulled from the outside, so the headlamp belt 6 maintains the current force.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
