Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of automatic door opening-and-closing mechanism, structure as depicted in figs. 1 and 2, and this automatic opening and closing door operates steadily, and safety is high.
Automatic door opening-and-closing mechanism as depicted in figs. 1 and 2, comprise gripper shoe 1 and the flexible axle 2, transmission mechanism and the rocker arm body 1 be oppositely arranged that are positioned in gripper shoe 1 and rocker arm body 24; rocker arm body 1 is connected with door-plate 1 and door-plate 28 with junction plate 26 respectively by junction plate 1 with rocker arm body 24; rocker arm body 1 and rocker arm body 24 are crank structure; one end of crank is all articulated with in gripper shoe 1, and the other end is articulated with on junction plate 1 and junction plate 26 respectively.
Transmission mechanism comprises main drive gear 15, primary transmission mechanism 12 and secondary drive mechanism 13, flexible axle 2 one end and main drive gear 15 one end hinged, be installed in gripper shoe 1 by flexible axle fixed mount 16 in the middle part of flexible axle 2.Main drive gear 15 is bent rod structure, and one end of bent rod connects flexible axle 2, and the middle part of bent rod is articulated with in gripper shoe 1, and the other end and the primary transmission bar 10 of bent rod are hinged.Gripper shoe 1 is also provided with dead point stop 9, primary transmission bar 10 is connected with limiting plate 17, when door-plate 1 and door-plate 28 are closed, limiting plate 17 snaps in dead point stop 9.
Primary transmission mechanism 12 is connected with main drive gear 15 by primary transmission bar 10, and secondary drive mechanism 13 is connected with primary transmission bar 10 by secondary transmission bar 11, and primary transmission mechanism 12 is connected with junction plate 26, and secondary drive mechanism 13 is connected with junction plate 1.Primary transmission mechanism 12 one end is connected with primary transmission bar 10, and the other end is connected with junction plate 26, and middle part is articulated with in gripper shoe 1.Secondary drive mechanism 13 one end is articulated with in gripper shoe 1, and the other end is connected with junction plate 1, and middle part is connected with secondary transmission bar 11.
