Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1,2,3, the utility model comprises closure plate 1, guide rail 2, master cylinder 8, supporting plate 5, wheel carrier 4, chain 3,6, hinge wheel 12, tensioning damping device 7, tensioning damping device 7 comprises backplate 13, tensioning cushion cylinder 15, connecting plate 18, two backplates 13 connect and compose support with connecting plate 18, one end of support is connected by pin 14 with hinge wheel 12, the other end is provided with tensioning cushion cylinder 15 and connects by pin 17, otic placode 16, between hinge wheel 12 and the tensioning cushion cylinder 15 closure plate 1 is set; Described master cylinder 8 is connected with wheel carrier 4, supporting plate 5, the both sides on wheel carrier 4 tops are provided with guide rail 2, the upper end of guide rail 2 is provided with supporting plate 5, the rear and front end of wheel carrier 4 all is provided with closure plate 1, one end of chain 3,6 is separately fixed at the rear and front end of supporting plate 5, at the hinge wheel 12 and the minor sprocket 19 of wheel carrier 4 front end and back end, the other end is fixedlyed connected with fuselage around the home.
Supporting plate 5 can be free to slide on guide rail 2 under the drive of master cylinder 8, and chain 3 one ends are fixed on the rear end of supporting plate 5, walks around the hinge wheel 12 of rear end then, walks around the minor sprocket 19 on the wheel carrier 4 again, is fixed on the fuselage then; Chain 6 one ends are fixed on the front end of supporting plate 5, walk around the hinge wheel 12 of front end then, walk around the minor sprocket 19 on the wheel carrier 4 again, are fixed on the fuselage then; Master cylinder 8 drives supporting plate 5 by chain 3,6 and slides on guide rail 2, and the speed of supporting plate 5 is twices of master cylinder 8 cylinder barrel movement velocitys.
