Abstract
The invention discloses a kind of guide frames of linear movement drive link, it includes driving device and drives the drive link with linear movement by driving device, it is additionally provided with the accessory part that a pair of of drive link carries out positioning and guiding, and the accessory part keeps drive link being limited in being in rolling contact in the limit channels of accessory part during linear movement with drive link.The present invention improves the positioning accuracy of screw motor to accomplish to only use the function that 2 screw motors can be achieved with lamps and lanterns automatic focusing by external accessory part.
Description
Technical field
The present invention relates to lamps and lanterns electrokinetic technique field, especially a kind of lamps and lanterns focusing system and its drive link that moves linearly
Guide frame.
Background technology
It is existing, for the guiding of transmission mechanism, the scheme of guide rod is typically used, is reliablely and stablely led to provide
To effect so that transmission mechanism stablizes output or movement according to guide direction.
Illuminator is widely used for screw motor when realizing a wide range of automatic focusing at present, is using single screw rod electricity
Machine will certainly occupy the light-emitting surface of lamps and lanterns central point as supporting point when focusing lens cephalic disc being pushed to carry out zoom, make shining for lamps and lanterns
Face forms evil mind effect in central point；Due to the design feature of screw motor itself, screw rod has by a relatively large margin at work
It shakes so that the hot spot that lamps and lanterns shine out is shaken therewith, has seriously affected the practical effect of lamps and lanterns, in Design of Luminaires
In order to avoid using the drawbacks described above that single screw motor is brought to generally require to use 3 screw motors simultaneously, it is evenly distributed on
Focusing function is realized around turret lens, but since the positioning accuracy of screw rod is not high when 3 screw motors work at the same time, and
Stationary problem between 3 motors easily causes turret lens to tilt, the failures such as stuck, in being also to increase multiple location guides
It solves these problems, does so and increase cost, also increase the volume of lamps and lanterns, this contradiction is in small design or compact
It is especially prominent when autozoom lamps and lanterns.
Invention content
The technical problem to be solved by the present invention is in view of the above shortcomings of the prior art, provide a kind of lamps and lanterns focusing system and
The guide frame of its drive link that moves linearly, proposes drive link novel guiding-positioning structure, and apply it to lamps and lanterns tune
To overcome problem of the prior art in burnt system.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of guiding of linear movement drive link
Structure comprising driving device and the drive link with linear movement is driven by driving device, be additionally provided with a pair of of drive link into
The accessory part of row positioning and guiding, the accessory part keep to pass with being in rolling contact during linear movement with drive link
Lever is limited in the limit channels of accessory part.
In above-mentioned technical proposal, the accessory part include at least an auxiliary stopper part and at least an idler wheel, the idler wheel and
The limit channels interted in the process in linear movement for drive link are formed between auxiliary stopper part.
In above-mentioned technical proposal, the auxiliary stopper part is idler wheel, the double rollers composition limit channels.
In above-mentioned technical proposal, the surface of the idler wheel is provided with for preventing drive link from being generated during linear movement
The limiting slot of offset.
In above-mentioned technical proposal, the auxiliary stopper part is provided with the hole interted for drive link, and is arranged on the inner wall of hole
There is the idler wheel.
In order to further solve the deficiencies in the prior art, a kind of lamps and lanterns focusing system is additionally provided, above-mentioned skill is applied
The guide frame of the linear movement drive link of art scheme, the mounted lamp on the drive link.
In above-mentioned technical proposal, the drive link is provided with two, and lamp installation is on the drive link described in two.
The beneficial effects of the invention are as follows：
1, traditional positioning and guiding is replaced in such a way that the limit channels that auxiliary stopper part and idler wheel form act on drive link
Mode of the bar as auxiliary, provides a kind of novel drive link positioning and guiding mode.
2, novel drive link positioning and guiding mode is applied in lamps and lanterns focusing system, instead of making for existing single screw rod
With solving the center light-emitting surface occupation problem of single screw rod.
3, instead of the use of existing 3 screw rods, drive link is to lamps and lanterns（Lamp cap disk）Such as there was only 2 supporting points, it can be effective
Lamps and lanterns stuck probability when reduction motor is asynchronous, quickly can make lamps and lanterns be restored to normal operating conditions in conjunction with driving device；
The frictional resistance of screw rod is greatly reduced in the characteristics of a pair of of idler wheel is rolled while standing screw using it, reduces the thrust of motor
Loss, effectively increases the positioning accuracy of screw rod, does not need additional increased location guide mechanism, has accomplished fitting structure letter
Single, compact, application scenario is flexible, and cost-effectiveness is apparent.
4, existing positioning and guiding bar scheme is compared, position error can be eliminated, improved for positioning accuracy.
