Specific implementation mode
As shown in Figs. 1-5, the one of which specific embodiment of the roller type fall block in a kind of vertical track, including lead
Rail 1 and moving trolley 2, guide rail is vertically arranged, and moving trolley moves up and down realization lifting in guide rail.The guide rail 1 includes one
Body formed fixed part 101, rolled portion 102 and driving portion 103, the cross section of the rolled portion 102 are the frame shape of upper opening
Structure, the fixed part 101 are molded over below the frame-type structure of rolled portion 102, and the driving portion 103 is molded over rolled portion 102
Frame-type superstructure.The quantity of the driving portion 103 is two, and two driving portions 103 are separately formed in the rolled portion 102
Frame-type structural openings above both sides.Rack 3 is fixed on the driving portion 103, specifically, the driving portion 103 is slot
Shape structure, the rack 3 are fixed in the slot of driving portion 103.The frame-type inner structural wall of the rolled portion 102 up and down distinguish by both sides
Rolling muscle 4 and lower rolling muscle 5 are formed, the quantity of the upper rolling muscle 4 is two, and two upper rolling muscle 4 are located at rolled portion 102
For frame-type structure close to open end both sides, the quantity of the lower rolling muscle 5 is that rolling muscle 5 is located at rolled portion 102 under two, two
