Abstract
The utility model relates to a blade driving mechanism for a multi-blade grating, wherein the blades of the multi-blade grating are connected with a radial lashing wire board, one end of a connecting rod is connected with the lashing wire board, and the other end of the connecting rod is connected with a feed screw driven by motors which are arranged crisscross on different layers. Due to the technical scheme described above, the utility model achieves reasonable structure. The radial lashing wire board reduces the bulk of the blade driving mechanism and enlarges the arranging space of the motors, thereby realizing small integer bulk, low cost, and convenient utilization of the multi-blade grating product.
Description
One, technical field
This utility model relates to multi-leaf optical grating, especially the vane drive mechanism of multi-leaf optical grating.
Two, background technology
Multi-leaf optical grating is to implement the conformal intensity modulated radiocurable visual plant of tumour 3 D.In order to obtain curative effect better, blade is more and more thinner, and the blade logarithm increases (being that launched field increases), and the parts of corresponding its vane drive mechanism are more and more.But, when, blade more when the number of blade is thin, because the size of motor is bigger, need provide enough installing spaces, otherwise motor does not dispose or interfere with each other during machine operation, thereby causes vane drive mechanism volume big, makes that the multi-leaf optical grating small product size is big, cost is high, the increase of the number of blade is restricted, and uses inconvenient.
Three, summary of the invention
The purpose of this utility model promptly provides the vane drive mechanism of the multi-leaf optical grating that a kind of volume is little, cost is low.
In order to realize this purpose, this utility model adopts following technical scheme: in the vane drive mechanism of multi-leaf optical grating of the present utility model, the blade of multi-leaf optical grating connects radial reinforcement plate, coupling bar one end connects reinforcement plate, another termination leading screw, leading screw is by driven by motor, and the multi-leaf optical grating blade pass is crossed radial reinforcement plate like this, comes driven vane to seesaw by the driven by motor leading screw.In this utility model, the motor layering is staggered, both can reduced volume, can guarantee that again the space of arranging of motor is enough.
After adopting technique scheme, this utility model is rational in infrastructure, and radial reinforcement plate makes the smaller volume of vane drive mechanism, and the space of arranging of motor increases, thereby multi-leaf optical grating product overall volume is dwindled, and cost reduces, and it is also convenient to use.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cut-away view of the present utility model.
Fig. 1, Fig. 2 are example with a lateral lobe sheet all.
Five, the specific embodiment
As shown in Figure 1 and Figure 2, in this utility model, the blade 1 of multi-leaf optical grating connects radial reinforcement plate 3, and coupling bar 2 one ends connect reinforcement plate 3, another termination leading screw 5, and leading screw 5 is driven by motor 4, and motor 4 layerings are staggered.
Claims (2)
1, a kind of vane drive mechanism of multi-leaf optical grating, it is characterized in that: the blade of multi-leaf optical grating connects radial reinforcement plate, and coupling bar one end connects reinforcement plate, another termination leading screw, leading screw is by driven by motor.
2, the vane drive mechanism of multi-leaf optical grating as claimed in claim 1, it is characterized in that: the motor layering is staggered.
