As preferably, hold the ring recess bottom surface equal with the thickness of the thickness of holding the base plate that encloses the inner side surface formation and mid-game.The thickness of base plate is promptly held the thickness of ring recess bottom surface to end circle inner side surface, and the thickness of base plate and the thickness of mid-game equate further to make in process of production the distortion contour projector to be consistent, and have effectively reduced product rejection rate, have improved the stability of product.
As preferably, described blade has two groups, is arranged between mid-game and two the end circles, and described two groups of blades vertically are provided with along mid-game circumferential edge place, and evenly are staggered between two groups of blades.The pitch of fins of blade all equates in each group blade, and blade one end is connected with the end circle, and the other end is connected with mid-game; Mid-game is a plate-like, and external frame is consistent with the end circle.
As preferably, in the middle of mid-game, be provided with shaft sleeve installation seat, around described shaft sleeve installation seat, be provided with plurality of strengthening ribs.Stiffening rib is connected with a side of shaft sleeve installation seat and mid-game respectively.
As preferably, in described shaft sleeve installation seat, axle sleeve is installed, described axle sleeve is provided with pin hole.There is the part of pin hole to stretch out shaft sleeve installation seat on the axle sleeve.
As preferably, on the blade of described pin hole correspondence, have mounting hole.On the blade of pin hole correspondence, have mounting hole and made things convenient for installation.
As preferably, be provided with annular knurl with the outer surface at the shaft sleeve installation seat place of matching at axle sleeve.Annular knurl is set on axle sleeve, makes fixing more firm between axle sleeve and the shaft sleeve installation seat.
Therefore, the present invention has following beneficial effect:
1, the present invention has effectively reduced cost of production because employing will hold circle, blade and mid-game with the injection molded mode of plastics one, has improved manufacturing efficiency, can effectively realize automated job simultaneously.
2, the present invention simultaneously adopts the structure that the thickness of sidewall on blade, mid-game and the end circle and base plate equates.Make that the distortion contour projector is consistent in the production process, effectively reduced product rejection rate, improved the stability of product.
