Abstract

The utility model relates to a fine-regulating focusing lamp, which is characterized in that a combined inner cover which is composed of a bottom cover and a cover cap is fixedly arranged in a cylindrical lamp casing, wherein an inner casing is sheathed on the peripheral surface of the inner cover, a positive thread groove segment and an inverse thread groove segment are arranged on the peripheral surface of an inner casing, and two sets of lenses are respectively clamped into the positive thread groove segment and the inverse thread groove segment on the inner casing after clamping points which are arranged on the edges of the two sets of lenses pass through a long groove on the cover cap of the inner cover. When the inner casing is rotated, the two sets of lens structures move in the opposite direction or the back direction; thus, the distance of a light beam can be adjusted.

Description

Fine setting focusing formula light fixture

The utility model relates to lighting, specifically is that a kind of light of adjusting penetrates far and near focusing formula light fixture.

Existing focusing formula light fixture, as shown in Figure 4, it is a kind of bleed type portable lamp of tunable optical, by lampshade 91, outer cover 92, ennation 93, members such as telescopic lamp tube 94 and bendable Zhe pipe are formed, concrete structure is, the front end of lampshade 91 is all-in-one-piece ennation 93 with it, the front end of ennation 93 is equiped with concavees lens 95, then have two keepers 96 on the ennation 93, be nested with telescopic lamp tube 94 on the ennation 93, the front end of telescopic lamp tube 94 is provided with convex lens 97, has locating slot 98 on the telescopic lamp tube, and locating slot 98 is wavy body, use with keeper 96 and constitute the location, retracting cylinder 94 can be used and carry out front and back and adjust to move, and to adjust suitable light beam, constitutes the illuminating effect of the best.Stretching tight before the lampshade 91 is provided with some blowing mouths 99, then is provided with ventilating duct 991 between lampshade body and lampshade shell, and wind can be delivered to ventilating duct via curved Zhe pipe by the fan blade fan and be blown out by blowing mouth, uses the effect that reaches air discharging and radiating.See that thus existing focusing formula light fixture is that the keeper that utilizes ennation slides before and after on the wave locating slot of telescopic lamp tube, can only single groove beat type is move that the distance between groove and groove can't be adjusted.

The purpose of this utility model provides a kind of fine setting focusing formula light fixture, make it to realize the continuous adjustment of stepless, and the entire length of lamp housing can remain unchanged in adjusting.

Realize the utility model of above-mentioned purpose, include lampshade, lamp, set of lenses and expansion regulating mechanism, compare with existing focusing formula light fixture, the utility model has all been done new design to relevant member, mainly be to have designed in the utility model on two groups of lens arrangements and an inner circumferential surface just to have, the inner housing of left-hand thread ditch section, make wherein one group of lens arrangement holding in the forward screw thread ditch of inner housing, another group lens arrangement holding is in the reverse thread ditch of inner housing, then when rotating inner housing, two groups of lens arrangements promptly take place in opposite directions or move dorsad, realize adjusting the purpose of light beam distance.So in the concrete structure of the present utility model: lampshade of the present utility model mainly is made of a tubular lamp housing, an inner cover and a lampshade, and wherein: an end of tubular lamp housing has the bottom surface, bottom center is provided with the through hole for the lamp socket insertion of lamp, and the other end is an opening; Inner cover is the combination inner cover with end cover and cover cap; Its cover is for there being bottom tube-like end, and is provided with the through hole that passes for lamp in center, the end, and the upper end of this end cover is an opening, and overlaps the following edge clipping of following said cover cap, and that also covers nearly lower end in this end offers a circular groove in appearance; Its cover cap be provided with all over the body number axis to elongated slot; Said end cover is with its bottom surface and lamp housing bottom surface interlocking mutually, again with cover cap interlocking mutually; The top of this inner cover is provided with a level crossing; Lampshade is that concave arc is planar, and there is a through hole that supplies lamp to pass at the center, and picks out several projections on its lower arcuate surface, has axially attacked screw on the projection; This lampshade is installed in the end cover, and the bottom surface of projection is contacted with the bottom surface of end cover, and locks with screw.Include two groups of fine setting lens in the set of lenses of the present utility model, every group of fine setting lens are made of an eyeglass and a protection ring; Protection ring includes two ring bodies, and the periphery of ring bodies one of therein is provided with several stuck points, uses the screw interlocking behind two ring bodies clampings, one lens, and snaps in the adjusting screw thread ditch of expansion regulating mechanism after making each stuck point pass elongated slot on the cover cap of inner cover.Expansion regulating mechanism in the utility model be one be enclosed within the lamp housing, the tubular inner casing on the inner cover periphery, the inner peripheral surface of this inner casing is provided with continuous screw thread ditch, and to make epimere screw thread ditch be plus thread, hypomere screw thread ditch is a left-hand thread; The inner peripheral surface of this nearly lower end of inner casing is provided with several ridges, be located in the circular groove that the inner cover appearance is oppositely arranged to stretch into, again the upper end of this inner casing exceed lamp housing apical margin partly and stride to lamp housing, appearance forms the inclined-plane with anti-skidding line; One group of fine setting lens snaps in the stuck point on the ring bodies of its protection ring in the epimere plus thread ditch of this inner casing, and another group fine setting lens snap in the hypomere left-hand thread ditch of this inner casing with the stuck point on the ring bodies of its protection ring.

Aforesaid the utility model can be equipped with convex lens near the lampshade place at inner cover.The utility model also can be designed to all only include an eyeglass to two groups of fine setting lens arrangements, several stuck points directly are set on the periphery of each eyeglass, snap in the adjusting screw thread ditch of inner casing after each stuck point being passed the elongated slot on the cover cap of inner cover, can realize finely tuning burnt purpose too.

Therefore main effect of the present utility model is: holding is in the screw thread ditch of inner casing after utilizing each stuck points of protection ring periphery of a pair of lens to pass the elongated slot of inner cover.Have in the structure of the present utility model one with the affixed inner cover of lamp housing; inner casing is nested with in lamp housing; on the inner cover outer peripheral face; and inner casing inner face lower end is stuck in the apparent circular groove of inner cover to count the projection thing; when rotation inner casing upper end; promptly allow the inner casing original place rotate; but thereupon just make lens and corresponding protection ring; reverse and move up and down; because of the stuck point of the protection ring of lens passes elongated slot; then protection ring is subject to the inner cover elongated slot; can only move up and down; promptly be subjected to inner casing rotation and force protection ring is moved; use the distance of adjusting the light ejaculation; tired is that lens and light produce far and near the variation, can pass lens according to the direction that light carries out, and the convex lens of process inner cover end face outwards penetrate.Because the utility model is with screw thread control, variations adjustment very among a small circle then can be arranged, more clearly adjusting the distance of ejaculation, and the outward appearance length of light fixture does not change, but really can adjust light.When implementing the utility model, can also not use the lens protection ring, and directly stuck point is located on the lens, then further simplified structure.

Embodiment of the present utility model as shown in drawings.The utility model is described in further detail below in conjunction with drawings and Examples.
