AI Technical Summary
Existing diving flashlights have a fixed beam angle that cannot be adjusted, resulting in a limited illumination range that cannot meet the needs of different diving missions.
By rotating the lamp head, the lamp holder moves up and down inside the tube. By using the cooperation of the limiting groove and the limiting block, the distance between the lamp holder and the lamp head lens can be adjusted, thereby achieving stepless adjustment of the beam angle.
It achieves stepless adjustment of the beam angle from 4° to 72°, allowing divers to flexibly switch between focused and diffused beams, thus improving ease of use.

[0001] The utility model relates to a diving flashlight field, specifically a light beam angle adjustable diving flashlight. BACKGROUND
[0002] Diving flashlight is a kind of underwater illuminating lamp. The earliest diving flashlight is only used for illuminating diver.
[0003] According to the statistics of international diving association, 82% of professional divers need to adjust the illumination range according to the task type, but the existing traditional diving flashlight is single light beam with fixed illumination range, cannot adjust the angle of light, thereby cannot adjust the illumination range, is spotlight or diffused light, makes the illumination light beam limited, is inconvenient to use, cannot meet the use demand of diving. Therefore, the light beam adjustable diving flashlight is a technical problem to be solved by the person skilled in the art. SUMMARY
[0004] The utility model discloses a light beam angle adjustable diving flashlight, which can adjust the distance between the lamp holder and the lens, adjust the angle of the light beam, and realize the stepless adjustment between spotlight and diffused light.
[0005] The utility model discloses a light beam angle adjustable diving flashlight, which can adjust the distance between the lamp holder and the lens, adjust the angle of the light beam, and realize the stepless adjustment between spotlight and diffused light.
[0006] A light beam angle adjustable diving flashlight, comprising a barrel and a lamp holder, the lamp holder is connected with the barrel, and the lamp holder is rotatably connected with the barrel, a lamp holder is slidably arranged at the top of the barrel, the lamp holder is electrically connected with the power supply in the barrel, a limiting groove is arranged on the side wall of the top of the barrel, a limiting block is arranged on the outer side of the lamp holder and slidably connected with the limiting groove, and the outer side of the limiting block is threadedly connected with the inner wall of the lamp holder.
[0007] Further, the limiting groove is symmetrically provided with two limiting blocks.
[0008] Further, the lamp holder is electrically connected with the power supply in the barrel through a spring wire.
[0009] Further, a plurality of sealing rubber rings are arranged at the rotatable connection between the lamp holder and the barrel.
[0010] Further, a plurality of anti-skid protrusions are arranged on the outer side of the lamp holder in the circumferential direction.
[0011] Compared with the prior art, the utility model has the beneficial effects that:
[0012] This patented design features a lamp head that is inserted into and rotatably connected to the barrel. The inner end of the lamp head has a convex lens, and a lamp holder slides within the barrel. The lamp holder contains a light source. A limiting groove and a limiting block restrict the lamp holder to sliding only up and down within the barrel. Because the outer side of the limiting block is threaded to the inner wall of the lamp head, rotating the lamp head causes the lamp holder to slide up and down within the barrel. This adjusts the distance between the light source and the convex lens inside the lamp head, thereby adjusting the angle of the emitted beam. This allows for stepless beam adjustment from 4° to 72°, ultimately achieving adjustable illumination range. In other words, it allows for stepless adjustment between focused and diffused light, making the illumination beam unrestricted, more convenient to use, and well-suited for diving applications.
