Description
Technical field
The utility model belongs to lighting apparatus manufacture field, and in particular to a kind of focus control of anti-light efficiency shake.
Background technology
It is well known that focus control is essential component part in lighting apparatus.But similar product currently on the market
All it is mostly to realize focusing function by using being the sliding block of plastic article, it is same to bring much although cost is relatively low
Unavoidable shortcoming, such as fit precision are poor, and resistance is big, and light efficiency shake is big during operation.
Therefore a kind of steady smooth focus control that can play the lighting apparatus for preventing light efficiency from shaking is found, is this field
Thing very urgent at present.
Utility model content
For this purpose, the technical problem to be solved by the utility model is to overcome the bottleneck of the prior art, so as to propose one kind
The novel steady smooth focus control for preventing light efficiency shake.
In order to solve the above technical problems, the utility model discloses a kind of focus control of anti-light efficiency shake, the focusing
Device includes a stabilization structure, and there are one focusing guide rod and a bearing composition and a limitings for the stabilization structure
Plate forms, and through-hole is provided on the bearing, and the focusing guide rod is connect across the through-hole with the limiting plate.
Preferably, through-hole is provided on the limiting plate, one end of the focusing guide rod passes through the through-hole.
Preferably, the focus control further includes a focusing lens fixed plate and a focusing motor fixing plate.
Preferably, the focusing lens fixed plate and focusing motor fixing plate and the limiting plate three are mutually parallel and set
It puts, by focusing, flange is connected；The focusing lens fixed plate is arranged on the limiting plate and the focusing motor fixing plate
Between.
Preferably, the other end and the focusing lens fixed plate phase of the stabilization structure setting in the focusing guide rod
Even.
Preferably, the through-hole that the useful focusing guide rod is set to pass through in the focusing lens fixed plate.
Preferably, the focusing lens fixed plate is connected with focusing lens.
Preferably, the focusing motor fixing plate is connected with motor.
More preferably, the bearing is linear bearing.
The above-mentioned technical proposal of the utility model has the following advantages compared with prior art, disclosed in the utility model flat
The focus control of steady cunning weakens light efficiency shake；Purpose using standard component linear bearing be and focusing guide rod fit precision
Height, focusing is steady smooth, weakens the problem of light efficiency is shaken, linear bearing unit price is higher than plastic article；Screw rod focusing motor work
When making, push focusing motor flange that focusing lens is made to move forward and backward in effective stroke；With great market prospects and
Economic value.

Specific embodiment
Embodiment
Present embodiment discloses a kind of focus control of anti-light efficiency shake, the focus control includes one to be prevented embodiment 1
Wobble structure, there are one focusing guide rod and bearing (linear bearing) composition and a limiting plate groups for the stabilization structure
Into being provided with through-hole on the bearing, the focusing guide rod is connect across the through-hole with the limiting plate.On the limiting plate
Through-hole is provided with, one end of the focusing guide rod passes through the through-hole.The focus control further includes a focusing lens and fixes
Plate and a focusing motor fixing plate.The focusing lens fixed plate and focusing motor fixing plate and the limiting plate three are mutual
It is arranged in parallel, by focusing, flange is connected；The focusing lens fixed plate is arranged on the limiting plate and the focusing motor
Between fixed plate.The stabilization structure setting is connected in the other end of the focusing guide rod with the focusing lens fixed plate.
The through-hole that the useful focusing guide rod is set to pass through in the focusing lens fixed plate.
The focusing lens fixed plate is connected with focusing lens.The focusing motor fixing plate is connected with motor.
It is using step：
1st, screw rod is focused motor respectively, focusing guide rod is fixed on focusing motor fixing plate；
2nd, focusing motor flange is screwed on screw rod focusing motor；
3rd, by focusing lens, linear bearing is fixed on after being fixed in focusing lens fixed plate again on focusing motor flange；
4th, focusing limiting plate is fixed on focusing guide rod, and it is the row of focusing to focus between motor fixing plate and limiting plate of focusing
Journey；
5th, magnet steel is sticked to glue in the circular hole in focusing lens fixed plate；
6th, magnetosensitive pcb board, magnetosensitive fixed plate are fixed on focusing motor fixing plate.
What deserves to be explained is the use of the purpose of standard component linear bearing is high with focusing guide rod fit precision, focusing is steady
It is smooth, the problem of light efficiency is shaken is weakened, linear bearing unit price is higher than plastic article.During screw rod focusing motor work, push and adjust
Burnt motor flange makes focusing lens move forward and backward in effective stroke.
Obviously, the above embodiments are merely examples for clarifying the description, and is not intended to limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And the obvious variation thus extended out or
Among the protection domain that variation is created still in the utility model.
