Embodiment
It is specific below in conjunction with the utility model to make the purpose of this utility model, technical scheme and advantage clearer
Technical solutions of the utility model are clearly and completely described for embodiment and corresponding accompanying drawing.
With reference to figure 1, the present embodiment provides the contour step trolley in library, including loads the sweep 2, Yi Jiyong of books
In promote sweep 2 handrail 1, sweep 2 below be evenly equipped with it is multiple can be by the road wheel group 15 of step 18.The road wheel group
15 include mounting seat 3, front-wheel 13, trailing wheel 9 and link member 12, and the upper surface of mounting seat 3 is welded below with sweep 2, front-wheel 13 and peace
Axis connection on front side of the lower end of seat 3 is filled, the one end of link member 12 is be hinged on front side of the lower end of mounting seat 3, the other end of link member 12 and the axle of trailing wheel 9
Connection, link member 12 are located at the outside of mounting seat 3.
The lateral surface of mounting seat 3 is provided with is caught in the chute 5 slided upwards for the rear end of lever piece 7, and for limiting
Link member 12 continues up positive stop 4.The outside middle portion of link member 12 is provided with lever piece 7, fulcrum member 14, trip lever
10 and spring 11, fulcrum member 14 in the middle part of the lateral surface of link member 12 with welding, and lever piece 7 is be hinged with fulcrum member 14, in trip lever 10
Be hinged in the middle part of the lateral surface of link member 12, trip lever 10 is located at the lower section of lever piece 7 in portion.
The trip lever 10 includes being used to hit the shock end 17 of step 18, for when hitting end 17 and hitting step 18 to
Inner side presses the solution lock end 16 of lever piece 7, hits end 17 and is connected by spring 11 with the front end of link member 12.The lever piece 7 wraps
The beveled end 8 dynamic for being unlocked 16 inside side pressures of end is included, and is moved into laterally when beveled end 8 is dynamic by inside side pressure
