Description
Technical field
The invention 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 part essential in lighting apparatus.But like product in the market
All it is by using being that the sliding block of working of plastics realizes focusing function mostly, although cost is relatively low, same bringing is a lot
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 area
Thing very urgent at present.
The content of the invention
Therefore, the technical problems to be solved by the invention are the bottleneck for overcoming prior art, it is a kind of new so as to propose
The steady smooth focus control for preventing light efficiency shake.
In order to solve the above technical problems, the invention discloses a kind of focus control of anti-light efficiency shake, the adjusting apparatus
Including a stabilization structure, the stabilization structure is made up of a focusing guide rod and a bearing and a limiting plate group
Into being provided with through hole on the bearing, the focusing guide rod is connected through the through hole with the limiting plate.
Preferably, through hole is provided with the limiting plate, one end of the focusing guide rod passes through the through hole.
Preferably, the focus control also 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 parallel to each other and set
Put, 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 passed through with the focusing guide rod is provided with 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.
It is more highly preferred to, the bearing is linear bearing.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art, disclosed in this invention steady smooth
Focus control, weaken light efficiency shake；Purpose using standard component linear bearing is high with focusing guide rod fit precision, and focusing is flat
Steady cunning, weakens the problem of light efficiency is shaken, and linear bearing unit price is higher than working of plastics；During screw rod focusing motor work, promote
Focusing motor flange makes focusing lens be moved forward and backward in effective stroke；With great market prospects and economic value.
Brief description of the drawings
In order that present disclosure is more likely to be clearly understood, specific embodiment and combination below according to the present invention
Accompanying drawing, the present invention is further detailed explanation, wherein
Fig. 1 is the structural representation of embodiment described device；
Fig. 2 is the explosive view of embodiment described device.
Reference is expressed as in figure：1- limiting plates；2- focusing guide rods；3- bearings；4- motors；5- focusing motors are fixed
Plate；6- focusing lens；7- focusing lens fixed plates；8- focusing flanges.
Embodiment
Embodiment
Present embodiment discloses a kind of focus control of anti-light efficiency shake, the adjusting apparatus are anti-including one for embodiment 1
Wobble structure, the stabilization structure is by a focusing guide rod and a bearing (linear bearing) forms and a limiting plate group
Into being provided with through hole on the bearing, the focusing guide rod is connected through 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 is also fixed including a focusing lens
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 passed through with the focusing guide rod is provided with 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 focusing motor flange again after being fixed in focusing lens fixed plate；
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 bonded in the circular hole in focusing lens fixed plate with glue；
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 working of plastics.During screw rod focusing motor work, promote and adjust
Burnt motor flange makes focusing lens be moved forward and backward in effective stroke.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.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 change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
