Description

Technical Field

[0001] The utility model belongs to the technical field of bicycle lighting, and particularly relates to a rotatably adjustable bicycle headlight. Background Art

[0002] A rotatable bicycle headlight generally refers to a headlight that can change the direction of the light beam by adjusting the angle of the lamp head. The purpose of this design is to enable riders to adjust the range and direction of the light as needed to adapt to different road conditions and environments, and to improve the safety and comfort of night riding. Adjusting the lens headlight can help riders adjust the range and direction of the light as needed to adapt to different road conditions and environments. For example, when riding on urban roads, the light can be adjusted to a wider range of illumination to improve visibility to pedestrians and vehicles. When riding on mountainous or rural roads, the light can be adjusted to a longer illumination distance to help riders better see the road conditions ahead. Therefore, adjusting the lens headlight can improve the safety and comfort of night riding.

[0003] Adjusting the bicycle lens headlight is usually achieved by rotating the lamp head or adjusting the knob on the lamp. These mechanisms allow the rider to change the illumination angle and direction of the light to adapt to different riding conditions. The principle of adjusting the illumination range of the bicycle lens headlight usually involves the design of the lens or reflector. By adjusting the angle of the lamp head, the incident angle of the light beam on the lens or reflector can be changed, thereby adjusting the illumination range. When the incident angle of the light beam increases, the illumination range will become wider; conversely, when the incident angle decreases, the illumination range will become narrower. Such a design enables the rider to adjust the illumination range and direction of the light as needed to improve the adaptability and safety of night riding. The problem with the above technology is that when the lens light is fixed to the front side of the bicycle through the mounting accessories, there is no component around the bicycle to protect it, and the bicycle is placed outdoors most of the time, so the outdoor sand and gravel can easily cause certain wear on the surface of the lens light. When the surface wear of the lens light is serious, it will affect its own lighting effect, thereby reducing the convenience of using the lens light. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a rotatable and adjustable bicycle headlight which can overcome the above problems or at least partially solve the above problems.

After the irradiation height of the lens lamp is adjusted to a suitable position by the rotating shaft block, the transmission rod can be pulled according to the trajectory of the opening of the movable hole. The transmission rod will drive the moving block to move during the movement, and the moving block will drive the positioning rod to move and stretch the tension spring during the movement. After the positioning rod moves to the inner cavity of the positioning groove, the protective shells on both sides are pulled to move toward the middle. When the protective shells on both sides are docked, the grooves formed by the docking of the rear sides of the two protective shells will be aligned and fitted with the front side of the lens lamp, thereby achieving the effect of protecting the mirror surface of the lens lamp. After the docking is completed, the transmission rod is released, the tension of the tension spring is contracted, and the positioning rod will be quickly driven to insert into the inner cavity of the positioning groove through the moving block. After the positioning rod is inserted into the inner cavity of the positioning groove, the position of the protective shell can be quickly fixed, thereby avoiding the situation that the protective shells on both sides cannot be fixed after docking.
