The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one: shown in figure one, originally bend towards mechanism mainly by bend towards joint 8, bend towards down save 6, rotating ring 10, small rod 11, handle 2 and back-moving spring 3 etc. constitute, wherein bend towards joint 8 two pin-and-holes are arranged, be articulated with bending towards down joint 6 and small rod 11 with pin A7 and pin B9 respectively, can pivot around pin.The bottom that bends towards down joint 6 is inserted in the umbrella rod 1, and a chute 61 that can slide up and down for the pin shape boss 111 on the small rod 11 is arranged on it.Small rod 11 is loaded on to bend towards down and saves in 6, and the head insertion is enclosed within the screw type teeth groove 101 that bends towards down the rotating ring 10 outside the joint 6 the pin shape boss 111 on it through bending towards down the chute 61 that saves, and makes small rod 11 and rotating ring 10 formation screw type transmissions.Handle 2 is enclosed within on the umbrella rod 1, and its top has Ka Er and draw-in groove to link together with buckle-type with draw-in groove and the Ka Er on the rotating ring 10, rotates together with driven rotary ring 10.And between rotating ring 10 bottoms and handle 2, be provided with a retainer ring 4 that is stuck in the groove that bends towards following joint 6, can avoid the friction of 2 on rotating ring 10 and handle.Following nest 5 skies are enclosed within on the handle 2, and are provided with a back-moving spring 3 between following nest 5 and the handle 2.Its effect is that postrotational handle 2 can automatically restore to original state under the effect of this back-moving spring 3.
The operation principle that present embodiment bends towards mechanism is as follows: when bending towards, clockwise rotate handle 2, rotate (the umbrella nest is motionless) by handle 2 driven rotary rings 10, the pin shape boss 111 that helicla flute 101 in the rotating ring orders about on the small rod moves up along the chute 61 that bends towards down joint, when moving on the small rod 11, by the power transmission of pin B9, eject and bend towards joint 8, bend towards joint 8 and rotate, thereby realize bending towards, be transformed into shown in Figure 2 by Fig. 1 around pin A; Hold handle and rotate round about, small rod moves down, and umbrella restores to the original state, and is promptly become shown in Figure 1 by Fig. 2.
Embodiment two: with reference to shown in Figure 3, the mechanism that bends towards of present embodiment mainly constitutes by bending towards part 13, rotating ring 10, support column 14, back-moving spring 3 and handle 2 etc., wherein bending towards part 13 is the certain thickness triangle member of a tool, one end undulate inclined-plane 131 matches with end face 103 on the rotating ring.Support column 14 is inserted in the umbrella rod 1, and rotating ring 10 is enclosed within on the support column 14 and by the flange on groove on it and the support column 14 and links together with buckle-type.Bend towards part 13 and be articulated in support column 14 usefulness pins 12, and can pivot around pin 12, the end face that bends towards part leans against on the end face with the suitable rotating ring in its waveform inclined-plane.Handle 2 is enclosed within on the umbrella rod 1, is respectively equipped with helicla flute 21 and boss 102 with the screw transmission on handle 2 and the rotating ring 10.Following nest 5 skies are enclosed within on the handle 2, and 2 on following nest 1 and handle are established back-moving spring 3.
Its operation principle is as follows: during parachute-opening, handle 2 screws in rotating ring 10 on earth, and following nest 5 is fixed, and finishes parachute-opening.In the time of need bending towards, be rotated further the rotation of handle 2 clockwise directions, rotate by handle 2 driven rotary rings 10; Because of being close to the end face 103 of rotating ring in the waveform inclined-plane 131 that bends towards part 13, descend along with the rotation of rotating ring so bend towards the A point that part 13 contacts with rotating ring 10, the rising of B point bends towards part and rotates around pin, the realization umbrella bend towards function.(see figure 5) when bending towards of umbrella reaches inclination maximum, the A point is in the lowest part of rotating ring by the highest point on original inclined-plane, continues equidirectional turning handle, and the A point is got back to the original place along the inclined-plane, and umbrella returns to original state.
Above-mentioned two embodiment are only for the usefulness that the utility model is described, and be not to be to restriction of the present utility model, relevant those skilled in the art, under the situation that does not break away from spirit and scope of the present utility model, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present utility model.
