Flashlight Zooming Structure

A flashlight zooming structure, comprising a main body and a zooming assembly threadedly connected to an end of a neck of the main body, the flashlight zooming structure being characterized in that:

• the zooming assembly comprises a cap, a cup seat, a lamp cup, and a middle annular element, the cap having a predetermined inner section formed as a threaded section, the cap having an open end peripherally provided with a plurality of inwardly extending projections, the cup seat having an outer periphery provided with at least two lugs, each said lug having an outer side formed as a threaded portion threadedly connected with the threaded section of the cap, the cup seat having a downwardly tapering inner periphery defining a relatively large opening and a relatively small opening, the relatively large opening being peripherally provided with a plurality of spaced and inwardly extending fasteners, the lamp cup being transparent and centrally formed with a convex lens, the lamp cup being received in the cup seat and limited in position by the fasteners of the cup seat, the middle annular element having an end extended with a receiving section, the receiving section being peripherally provided with notches of a predetermined depth, the lugs on the outer periphery of the cup seat being inserted in and movable along the notches, the middle annular element having an inner periphery provided with threads threadedly connected with an externally threaded portion of the neck of the main body, the middle annular element having an opposite end concavely provided with an annular groove, the projections of the cap being engaged with the annular groove to limit the cap and the middle annular element in position;
• wherein the zooming assembly is operated by rotating the cap in a desired direction so that the cup seat in the zooming assembly is moved upward or downward along the notches and the lamp cup received in the cup seat is moved along with the cup seat, thus allowing light emitted by a lighting unit at the end of the neck of the main body to project outward through the transparent lamp cup in the zooming assembly as a divergent or convergent light beam.
