Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1 and 2, the utility model provides a pair of preforming of rotating shuttle, it includes arc perisporium 21, connects the limiting plate 23 of detaining along 22 and connecting in the bottom of arc perisporium 21 on the top of arc perisporium 21, detain along 22 and the relative setting of limiting plate 23, detain along 22 perpendicular to arc perisporium 21, the radial locating hole 24 that is provided with of arc perisporium 21, the bottom of outer shuttle frame is provided with the spacing step of contradicting with limiting plate 23.
In practical application, the pressing sheet is assembled on the outer shuttle frame, so that the arc-shaped peripheral wall 21 is attached to the outer side wall of the outer shuttle frame, the buckle edge 22 and the guide groove of the outer shuttle frame are enclosed to form a channel, the buckle edge 22 is used for limiting the guide rail of the inner shuttle frame in the guide groove, the guide rail can rotate in the channel relative to the outer shuttle frame, the limiting plate 23 is abutted against the limiting step to limit the pressing sheet, and finally, the pressing sheet is fixedly installed on the outer wall of the outer shuttle frame through the positioning hole 24 by the pressing sheet locking screw and rotates along with the outer shuttle frame. The utility model has the advantages of simple structure, set up limiting plate 23 through the bottom at arc perisporium 21 in order to carry on spacingly to the preforming, guaranteed position accuracy and the stability of preforming fixed mounting at outer shuttle frame, because of the relative outer shuttle frame slope of preforming or skew cause the size of passageway inhomogeneous when avoiding the fixed mounting preforming for outer shuttle frame is little with the frictional resistance of interior shuttle frame relative rotation, stability is good, outer shuttle frame and interior shuttle frame be difficult for wearing and tearing, the production of noise reduction.
