Description of drawings
Fig. 1 is the structural representation of the latch gear of the utility model one preferred embodiment;
Fig. 2 is the structural representation of another state of latch gear shown in Figure 1.
Embodiment
As shown in Figure 1, it is the structural representation of the latch gear 10 of the utility model one preferred embodiment, and latch gear 10 comprises: rocking arm 101, connecting rod 102, rotating disk 103, the first fixed rotating shaft 104, the second fixed rotating shaft 105, position limit pin 106, two pull bars 107, two lock pins 108 and spring 109.
The middle part of rocking arm 101 rotatably fixedly mounts by the first fixed rotating shaft 104.
Be that described the first fixed rotating shaft 104 positions are fixed, rocking arm 101 can be around 104 rotations of the first fixed rotating shaft.In the present embodiment, described rocking arm 101 is kink shape, and crooked place is connected with described the first fixed rotating shaft 104.
Rotating disk 103 rotatably fixedly mounts by the second fixed rotating shaft 105.
The position that is described the second fixed rotating shaft 105 is fixed, and rotating disk 103 can be around 105 rotations of the second fixed rotating shaft.
One end of connecting rod 102 is rotatably connected with an end of rocking arm 101, and the other end is rotatably connected with rotating disk 103 marginal positions.The mode of being rotatably connected can cooperate realization by rotating shaft and circular hole.
In the present embodiment, rotating disk 103 is cam structure, and described connecting rod 102 is connected to the raised position of cam rotatably.
Offer on the rotating disk 103 take the axle center of the second fixed rotating shaft 105 as the arc steering channel 131 in the center of circle, also be provided with projection 132, the second fixed rotating shafts 105 in the rotating shaft 103 between steering channel 131 and projection 132.
One end of spring 109 is connected with position limit pin 106, and the other end is connected with projection 132 on the rotating disk 103.
One end of two pull bars 107 is the rotatable position that is positioned at the second fixed rotating shaft 105 both sides on the rotating disk 103 that is connected to respectively.
