Abstract
The utility model discloses a kind of focus controls, including lamp body and light cover, lamp cover is on lamp body, lens are installed in light cover, it is equipped with focusing drum in the lamp body, a spring is equipped between focusing drum and lamp body, is fixed with LED lamp panel at the top of focusing drum, it is cased with turntable engaged therewith outside focusing drum, drives focusing drum to move up and down when turntable rotates；The turntable bottom end is evenly distributed with multiple V-arrangement shifting blocks, uniformly distributed multiple inverted V-shaped convex blocks on drum outer wall of focusing, and forms the V-shaped groove being caught in for V-arrangement shifting block between two adjacent inverted V-shaped convex blocks.Thus the focus control structure designed is simple, focusing is convenient.
Description
Technical field
The utility model relates to field of illumination lamp technology, are especially a kind of focus control used on lamps and lanterns.
Background technique
The lamps and lanterns of the prior art often do not have focusing function, and the light that lamps and lanterns irradiate is more single, are not suitable for
It is used in fact under different working environments, and has the fitting structure of focusing function excessively complicated, and using trouble.
Utility model content
In view of the defect of the above-mentioned prior art, the purpose of this utility model is that: a kind of focus control is provided, structure is simple
And it is easy to use.
The technical solution of the utility model is: a kind of focus control, including lamp body and light cover, and lamp cover is in lamp body
On, lens are installed in light cover, focusing drum is equipped in the lamp body, a spring, focusing drum top is equipped between focusing drum and lamp body
Portion is fixed with LED lamp panel, and turntable engaged therewith is cased with outside focusing drum, drives focusing drum to move up and down when turntable rotates；
The turntable bottom end is evenly distributed with multiple V-arrangement shifting blocks, uniformly distributed multiple inverted V-shaped convex blocks on drum outer wall of focusing, and adjacent two
The V-shaped groove being caught in for V-arrangement shifting block is formed between inverted V-shaped convex block.
Further, the lamp body inner wall is equipped with multiple groups track muscle, and the quantity of every group of track muscle is two, two tracks
A sliding slot is formed between muscle, the bottom end of focusing drum is equipped with fixture block equal with sliding slot quantity and with sliding slot cooperation, and focusing drum is put into
In lamp body, and fixture block is caught in sliding slot.
Further, the spring is put into lamp body, focusing drum bottom pressing spring.
Further, it is set at the top of the focusing drum there are two screw hole, sets that there are two corresponding screw hole settings in LED lamp panel
Circular hole, LED lamp panel is fixed at the top of focusing drum by way of screw connection.
Using a kind of focus control provided by the utility model, the beneficial effect is that: turntable is rotated when use, turntable turns
Focusing drum is able to drive after dynamic to move up and down, after focusing drum position change, the distance between LED lamp panel and lens change,
To change focal length, structure is simple and easy to use.

Specific embodiment
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing
Unrestricted feature description is as follows:
As shown in Fig. 1-Fig. 4, a kind of focus control, including lamp body 1 and light cover 2, light cover 2 are covered on lamp body 1, in light cover 2
Lens 3 are installed, are equipped with focusing drum 4 in lamp body 1, a spring 5 is equipped between focusing drum 4 and lamp body 1, is fixed at the top of focusing drum 4
There is LED lamp panel 6, turntable 7 engaged therewith is cased with outside focusing drum 4, drives focusing drum 4 to move up and down when turntable 7 rotates；Turntable 7
Bottom end is evenly distributed with multiple V-arrangement shifting blocks 8, uniformly distributed multiple inverted V-shaped convex blocks 9 on 4 outer wall of focusing drum, between two adjacent inverted V-shaped convex blocks 9
Form the V-shaped groove 10 being caught in for V-arrangement shifting block 8.
Focusing drum 4 in order to facilitate the installation of, 1 inner wall of lamp body are equipped with multiple groups track muscle 11, and the quantity of every group of track muscle 11 is
Two, form a sliding slot 12 between two track muscle 11, the bottom end of focusing drum 4 be equipped with it is equal with 12 quantity of sliding slot and with sliding slot 12
The fixture block 13 of cooperation, focusing drum 4 are put into lamp body 1, and fixture block 13 is caught in sliding slot 12.
In order to facilitate the use of spring 5, spring 5 is put into lamp body 1,4 bottom pressing spring 5 of focusing drum.
It in order to facilitate fixed LED lamp panel 6, is set at the top of focusing drum 4 there are two screw hole 14, sets that there are two right in LED lamp panel 6
The circular hole 15 for answering screw hole 14 to be arranged, LED lamp panel 6 are fixed on 4 top of focusing drum by way of screw connection.
A kind of focus control provided by the utility model, turntable 7 is rotated when use, and turntable 7 is able to drive tune after rotating
Burnt cylinder 4 moves up and down, and after 4 position change of focusing drum, the distance between LED lamp panel 6 and lens 3 change, to change
Focal length.
Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model
Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap
