Abstract
The utility model relates to a focusing mechanism for a medical LED shadowless lamp. The focusing mechanism comprises a pressing rod, a lamp shell, an adjusting lead screw, a stroke sleeve, a disc, a spherical fan blade and LED lamp bead modules. The pressing rod and the lamp shell are fixedly connected. The adjusting lead screw is connected to the center of the pressing rod in a pivoted mode. The disc is contained in the lamp shell, and the stroke sleeve is fixed to the center of the disc. The stroke sleeve and the adjusting lead screw are matched. The spherical fan blade is hinged to the disc. The LED lamp bead modules are arranged on the disc and the spherical fan blade in an annular layering mode. The focusing mechanism for the medical LED shadowless lamp has the advantages of being simple in structure, capable of carrying out focusing conveniently, good in effect, high in precision and the like.
Description
[technical field]
The utility model relates to a kind of composition mechanism of medical shadowless lamp, is specifically related to a kind of focus adjusting mechanism of medical LED shadowless lamp, belongs to technical field of medical instruments.
[background technology]
LED shadowless lamp in the market, great majority adopt the single led lamp pearl of adjustment to realize the effect of focusing.There is following defect: adjust complexity, the effect of focusing is poor, can not meet the demand of medical operation illumination, medical LED shadowless lamp can not well be promoted.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of focus adjusting mechanism with structure improved medical LED shadowless lamp, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, focus effect good and the focus adjusting mechanism of medical LED shadowless lamp easy to use.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of focus adjusting mechanism of medical LED shadowless lamp, and it comprises depression bar, lamp housing, adjusting screw mandrel, stroke sleeve, disk, sphere fan sheet and LED lamp pearl module; Wherein, described depression bar and lamp housing concrete mutually; Described adjusting screw mandrel is articulated in the central authorities of depression bar; Described disk is contained in lamp housing, and its central authorities are fixed with described stroke sleeve; Described stroke sleeve and adjusting screw mandrel match; Described sphere fan sheet is articulated with on disk; The circular level of described LED lamp pearl module is arranged on disk, sphere fan sheet.
The focus adjusting mechanism of medical LED shadowless lamp of the present utility model is further set to: in the bottom of described lamp housing, one transparent glass is installed.
The focus adjusting mechanism of medical LED shadowless lamp of the present utility model is further set to: described sphere fan sheet is along the circumferential directions of disk, and concrete number is 4-8 sheet.
Compared with prior art, the utlity model has following beneficial effect: the focus adjusting mechanism of medical LED shadowless lamp of the present utility model has simple in structure, convenient, effective, the plurality of advantages such as precision is high of focusing.
[accompanying drawing explanation]
Fig. 1 is the cutaway view of the focus adjusting mechanism of medical LED shadowless lamp of the present utility model.
[specific embodiment]
Refer to shown in Figure of description 1, the utility model is a kind of focus adjusting mechanism of medical LED shadowless lamp, and it is made up of several parts such as depression bar 1, lamp housing 2, adjusting screw mandrel 5, stroke sleeve 7, disk 8, sphere fan sheet 3 and LED lamp pearl modules 6.
Wherein, described depression bar 1 and lamp housing 2 concrete mutuallies.Described adjusting screw mandrel 5 is articulated in the central authorities of depression bar 1.One transparent glass 9 is installed in the bottom of described lamp housing 2.
Described disk 8 is contained in lamp housing 2, and its central authorities are fixed with described stroke sleeve 7.And described stroke sleeve 7 and adjusting screw mandrel 5 match.
Described sphere fan sheet 3 is articulated with on disk 8.Specifically, described sphere fan sheet 3 is along the circumferential directions of disk 8, and concrete number is 4-8 sheet, and each sphere fan sheet 3 is hinged on disk 8 by the parts 4 that are rotatably connected.
Described LED lamp pearl module 6 respectively circular level is arranged on disk 8, sphere fan sheet 3.
The operation principle of the focus adjusting mechanism of medical LED shadowless lamp of the present utility model is as follows: adopt manual or electronic mode to drive and regulate screw mandrel 5 to rotate, regulating screw mandrel 5 to rotarily drive stroke sleeve 7 axially moves, and stroke sleeve 7 is owing to being connected with disk 8, thereby can drive disk 8; In the time that disk 8 is done axially-movable, drive sphere fan sheet 3 to rotate along the parts 4 that are rotatably connected, thereby change the radius of curvature of sphere fan sheet 3, thereby reach the effect of focusing.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
