Specific implementation mode
Technical scheme of the present invention is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1,2,3, 4, a kind of rudder face folds rotating mechanism, including rudder face 1, axis pin 2, axle sleeve 3, bearing spider 4,
Hollow shaft 5, fixed pin 6, push rod 7, support shaft 8, motor 9, sliding block 10, bearing 11 and spring 12, the upper and lower ends of bearing spider 4
It is fixedly installed a bearing 11 respectively, the hollow shaft 5 is threaded through in two bearings 11 up and down, and 5 upper and lower side of hollow shaft connects respectively
It is connected to rudder face 1,5 upper end of hollow shaft is connect by the axle sleeve 3 being arranged thereon with rudder face 1, and the portion in axle sleeve 3 is stretched into 1 lower end of rudder face
Divide and connect with axle sleeve 3 by axis pin 2, and rudder face 1 is pivotally connected with axle sleeve 3, rudder face 1 can be rotated around axis pin 2, the lower end of hollow shaft 5
It is pivotally connected rudder face 1 by axis pin, spring 12 is provided in hollow shaft 5, the upper and lower ends portion of spring 12 is respectively arranged with sliding block 10,
Inclined-plane A13 is provided on sliding block 10, be provided on rudder face corresponding with sliding block 10 1 with the matched inclined-plane B14 of inclined-plane A13,
Pass through sliding block upward sliding so that inclined-plane A13 pushes inclined-plane B14 to realize rudder face 1 around the rotation of axis pin 2, inclined-plane A13 and inclined-plane
After B14 fittings completely, rudder face 1 is in locking state；One end of the push rod 7 is fixedly connected with the fixed pin 6 of vertical shape arrangement,
There are two fixed blocks, two fixed blocks to be arranged in corresponding up and down for setting on the outer circumference surface of hollow shaft 5, and fixed pin 6, which is fixed, to be connected
