[0026] The specific embodiment is a roller 403 type fast adjustment headband for headlamp, the structure diagram is shown in Figures 1-4 , which comprises:

[0027] The lamp holder plate 2 is located at the front end and the battery powered part 1 is located at the rear end, and the battery powered part 1 is provided with two threading holes 101 on both sides;

[0028] Two strip headbands 3 are arranged symmetrically on the left and right sides, and the two ends of each strip headband 3 are respectively fastened to the lamp holder plate 2 and the battery powered part 1;

[0029] The roller 403 adjustment assembly 4 is detachably connected to each strip headband 3, which is used to adjust the length of the strip headband 3 on the left and right sides.

[0030] When wearing the headlamp, according to the user's head, loosen the strip headband 3, place the lamp holder plate 2 on the user's forehead, place the battery powered part 1 on the user's back of the head, and wear it on the head, and then adjust the length of the strip headband 3 on the left and right sides through the roller 403 adjustment assembly 4, so as to realize the operation of fast wearing.

[0031] Further, as shown in Figure 3 , each roller 403 adjustment assembly 4 comprises a traction block 401, a through slot hole 402 opened at one end of the traction block 401, a roller 403 rotatably installed at one end of the traction block 401, and a traction belt 404 fixedly installed at the other end of the traction block 401. Specifically, by providing the traction belt 404 and the roller 403, the strip headband 3 and the roller 403 are rolled to realize fast adjustment and one-step operation, which is completely different from the troublesome operation of traditional day buckle, so as to greatly facilitate the user to adjust and wear the strip headband 3.

[0032] Further, as shown in Figure 1 , Figure 2 and Figure 4As shown, one end of the strip headband 3 is fixedly installed on the battery-powered part 1, and the other end of the strip headband 3 first passes through the through-slot hole 402 to bypass the roller 403 and then passes through the belt passing hole 101 to make the other end of the strip headband 3 fixedly connected to the lamp holder plate 2. The traction belt 404 pulls the traction block 401 to drive the roller 403 to roll to adjust the length of the strip headband 3, including the length of the strip headband 3 between the belt passing hole 101 and the lamp holder plate 2, so as to realize the quick and tight wearing of the strip headband 3 on the head of the user.

[0033] Further, the traction belt 404 is fixedly connected with a Velcro male surface on one side close to the strip headband 3, and the strip headband 3 is fixedly connected with a Velcro female surface on one side close to the traction belt 404. When the traction belt 404 pulls the traction block 401 to drive the roller 403 to roll to adjust the length of the strip headband 3 between the belt passing hole 101 and the lamp holder plate 2, the Velcro male surface on the traction belt 404 is attached to the Velcro female surface on the strip headband 3 to complete the fixation of the strip headband 3.

[0034] One end of the strip headband 3 first passes through the through-slot hole 402 to bypass the roller 403 and then returns to pass through the belt passing hole 101 to form a bending area, and the roller 403 is located in the bending area. The roller 403 is in rolling contact with the strip headband 3 to reduce the friction therebetween, so as to realize the one-step operation of quick adjustment.

[0035] When the length of the strip headband 3 between the battery-powered part 1 and the lamp holder plate 2 is too long, the user only needs to pinch the traction belt 404 away from the traction block 401 to pull the traction block 401 to move towards the lamp holder plate 2, which can drive the roller 403 to move synchronously in the bending area. When the roller 403 moves in the bending area, it can pull the strip headband 3 to make the bending part of the strip headband 3 longer, so as to reduce the length of the strip headband 3 between the battery-powered part 1 and the lamp holder plate 2. When the length of the strip headband 3 between the battery-powered part 1 and the lamp holder plate 2 matches the user, the traction belt 404 is stopped from moving and is attached to the strip headband 3 through the cooperation of the Velcro male surface and the Velcro female surface. At this time, the adjustment of the length of the strip headband 3 is completed, and the whole operation process can be completed by simply pulling.

[0036] Of course, the length of the Velcro female surface is equal to the length of the strip headband 3. By setting the length of the Velcro female surface to be equal to the length of the strip headband 3, the length adjustment range of the strip headband 3 is increased.

[0037] In conclusion, the utility model discloses a replace traditional day button with the design roller 403 adjustment assembly 4, utilize the traction belt 404 to pull the traction block 401 drive roller 403 in the strip head band 3 bending area rolling, and will traction belt 404 through magic paste and stick on strip head band 3, only need to pull the rolling and the adhesion fastening in the whole wearing process, make the length of strip head band 3 get quick tension and the adjustment of the quick release, have the advantage that quick rolling operation and convenient length adjustment.

[0038] All the technical features in the embodiment can be freely combined according to actual needs.

[0039] The above embodiment is a preferred implementation scheme of the utility model, and in addition, the utility model can be implemented in other manners, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
