Patent ID: 8641226

Claim:
A flashlight lamp rotation structure, comprising: a flashlight body having an upper end concavely defined with an accommodating region of a preset width; a rotatable body provided concavely therein with a receiving space; a connecting element inserted into the rotatable body and having at least two sides each coupled to an illumination light source; a lever penetrating the upper end of the flashlight body and the rotatable body; a receiving ring member screwed to a thread segment at the upper end of the rotatable body; and a transparent lampshade engaged with the receiving ring member, wherein the rotatable body is disposed on the accommodating region concavely defined at the upper end of the flashlight body, wherein through holes of preset diameters are formed at centers of support segments flanking the accommodating region of the flashlight body, such that tube segments extending outward from the two sides of the rotatable body, respectively, can be inserted into the through holes, wherein a curved concave portion is formed on an outer surface of the rotatable body laterally to abut against a limiting element received in the cavity formed in the flashlight body and facing a preset direction and pushed outward by a spring, wherein a lever coupled to the spring is inserted between the tube segment on one side of the rotatable body and the through hole formed in the flashlight body and corresponding in position to the tube segment, wherein a mask encloses the lever and is fixed to the flashlight body, wherein the connecting element having a surface concavely provided with at least two recesses facing preset directions is received in the receiving space of the rotatable body, wherein a penetrating hole is formed at a center of the connecting element to penetrate the connecting element, such that the lever abutting against the flashlight body resiliently can be moved and inserted into the penetrating hole or withdrawn from the penetrating hole resiliently, wherein a protruding portion is formed on the rotatable body to face a preset direction and inserted into the recesses disposed concavely on the surface of the connecting element so as to restrict the direction of the connecting element appropriately, wherein at least two limiting protruding portions extending outward from a rim of the connecting element in preset directions provide appropriate rotational restriction in conjunction with a stop segment formed at the rotatable body; wherein the thread segment at the upper end of the rotatable body is screwed to the receiving ring member, and a transparent lampshade is engaged with the upper end of the receiving ring member, such that a flashlight capable of lamp rotation can be assembled, wherein the illumination light source coupled to the lamp movably pivotally coupled to the upper end of the flashlight body undergoes a preset change of a color of lamp light to meet a need for a flashlight illumination direction, or the lamp rotates in a preset direction, so as to provide flashlight illumination flexibly.
