Further, brush comprises multiple sub brush independent of each other, and multiple sub brush is arranged in a linear on body diapire.
Further, rolling disc is opened vertically axle core installing hole processed, one end of rotating shaft core is fitted to axle core installing hole, thus realizes rolling disc and rotate with rotating shaft core; Rolling disc is installed in the containing cavity of axle sleeve, and the other end of rotating shaft core stretches out from beam barrel body.
Further, rotating shaft core is shaped with annular slot, equipped silica gel sealing ring on annular slot, axle core is coordinated with axle sleeve by silica gel sealing ring, plays water-proof function, classification of waterproof IP67 level.
Further, body diapire is fixedly mounted with the coding terminal of outupt coded signal.
Further, the outer wall of the beam barrel body of axle sleeve is shaped with thread, the present invention and installation panel to be fixed so that spin with nut.
Further, the outer wall of the beam barrel body of axle sleeve is shiny surface, to realize the present invention and installation panel plug-in type is fixed.
Further, axle sleeve outer wall is shaped with the installation foot installed with circuit board, so that the present invention and circuit board are installed.
Beneficial effect of the present invention is:
One, the present invention has four features in combining form: 1) shell fragment and rolling disc radially configure, and rolling disc, Location resilient piece and positioning tooth are radially configured; 2) body diapire is fixedly mounted with brush; 3) circuit wafer is fixedly mounted with rolling disc vertically; 4) the whole circle of inwall of the accommodating cavity of axle sleeve has been shaped with the positioning tooth rotating positioning action, the outer wall of accommodating cavity is the first housing department as encoder shell, body sidewall is the second housing portion as encoder shell, and the position in the first housing department and second housing portion and shape form complementary fit.Owing to adopting this combining form, the position causing inventive encoder to occupy on circuit boards is very little.
Its two, the outer wall of accommodating cavity is the first housing department as encoder shell, and body sidewall is the second housing portion as encoder shell, and the position in the first housing department and second housing portion and shape form complementary fit; By the card plugging structure be shaped with on the first housing department and second housing portion, encoder is loaded into entirety.Like this, encoder just can be loaded into entirety by the first housing department and second housing phase plug-in card, no longer need riveted joint, assembly technology is simplified, also make the globality enhancing in appearance of encoder encodes device.
its three,the anglec of rotation is 360 degree, and the anglec of rotation maximizes.
