Problems solved by technology

[0002] In the past, the head loose adjustment device of the headlight used a simple hanging strap method. The disadvantage of this is that the frictional resistance between the rope or the strap and the hanging groove becomes larger, which makes it easy for the user to loosen the rope when the adjustment is loose. The phenomenon of tightness or tightness of the lower rope and looseness of the upper rope makes it uncomfortable to wear
Either the user has to adjust the looseness of the wearing in advance before wearing it, which makes it inconvenient and unsafe to use at night

Embodiment Construction

[0013] like figure 1 and figure 2 , image 3 As shown, a head size adjusting device for a headlight includes a rope or a belt 1 and a lamp cap 4, the two sides of the lamp cap 4 are provided with runners 2, the circumference of the runner 2 is provided with grooves, and the rope or belt 1 After wrapping around the groove of the runner 2, the two ends are passed through the holes of the regulator 3 respectively. A runner upper cover 21 is arranged outside the runner 2 . The shaft of the runner 2 is rotatably connected to both sides of the lamp cap 4 . The structure of the regulator 3 is as follows: it includes a first connecting part 31 and a second connecting part 32 that can move relatively therewith. Both the first connecting part 31 and the second connecting part 32 are provided with a rope or belt 1 to pass through. The through hole 34 of the first connecting part 31 and the second connecting part 32 is provided with a spring 33, when the first connecting part 31 is p...

Abstract

The invention discloses a device for regulating the size of a head of a head lamp. The device comprises ropes or belts and a lamp cap. Rotating wheels are placed on two side edges of the lamp cap, and a groove is formed on the circumference of each rotating wheel. After the ropes or the belts are wound around the grooves in the rotating wheels, two tail ends respectively penetrate through a hole of a regulator. The regulator structurally comprises a first connection part and a second connection part, wherein the second connection part can move opposite to the first connection part, the first connection part and the second connection part are respectively provided with a through hole through which the ropes or the belts can penetrate, and a spring is placed between the first connection part and the second connection part. When the first connection part is pressed down, the through hole in the first connection part and the through hole in the second through hole are aligned, and the ropes or the belts can move freely in the holes. When a hand loosens the first connection part, the first connection part is bounded, and the ropes or the belts are clamped.

Description

technical field [0001] The invention relates to a head size adjusting device of a headlamp. Background technique [0002] In the past, the head loose adjustment device of the headlight used a simple hanging strap method. The disadvantage of this is that the frictional resistance between the rope or the strap and the hanging groove becomes larger, which makes it easy for the user to loosen the rope when the adjustment is loose. If the lower rope is tight or the upper rope is loose, it will cause uncomfortable wearing. Either the user will wear it after adjusting the looseness of the wearing in advance before use, which makes it inconvenient and unsafe to use at night. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a head size adjusting device for a headlight with reasonable design and convenient use. [0004] In order to solve the above-mentioned technical problems, a device for adjusting the size of the head o...
