Title:
PRESSURE-RESISTANT AND MAGNETICALLY CONTROLLED ZOOM FLASHLIGHT
Document Type and Number:
WIPO Patent Application WO/2017/128571
Kind Code:
A1
Abstract:
Disclosed is a pressure-resistant and magnetically controlled zoom flashlight, comprising a lamp holder (10), the lamp holder (10) being provided with a mounting cavity (11); an optical assembly (20); a zoom assembly (30), the zoom assembly (30) comprising a heat dissipation seat, a linkage ring (31), a first matching part (32) and a second matching part (37), wherein the first matching part (32) is mounted on the lamp holder (10) and is pivotally matched with the lamp holder (10), the first matching part (32) is located on an outer circumference of the mounting cavity (11), the linkage ring (31) is movably mounted in the mounting cavity (11), the second matching part (37) is provided on an outer surface of the linkage ring (31), the second matching part (37) is linked with the first matching part (32) by way of magnetic attraction, the linkage ring (31) is screw connected at one end of the heat dissipation seat close to an opening, one end of the heat dissipation seat away from the opening moves along a depth direction of the mounting cavity (11); a light source assembly (40); and a circuit control assembly (50). The pressure-resistant and magnetically controlled zoom flashlight achieves optical zooming by means of the two matching parts which magnetically attract to each other matching with each other so the flashlight zooms flexibly under the maximum deep water pressure, facilitating operation.
