Resistance ring 5042 is threadedly coupled,
Above-mentioned resistance ring 5042 increases resistance by threaded post 5041 and the friction of turntable 5024, reduces second gear 5025
The speed of downslide.
The check pawl 5023b is L-type structure, and one end is used to support entirety, will not translate into, the resistance ring
5042 is identical as 5024 diameter of turntable, and 5042 surface of resistance ring is equipped with anti-skid chequer.
The principle of the present invention: first pulling out pull rod 7, the pull rod locating slot 6 for then allowing pull rod 7 to be fastened on luggage case 1,
The inclination of luggage case 1 was fallen on step, and pull rod 7 is dragged, and the plate 5021a that creeps of the hangnail on gear band 5021 is buckled on ledge surface
Increase resistance, avoids 5021 surface of gear band is excessively smooth from causing to glide, when gear band 5021 is up slided with luggage case 1,
It drives first gear 5022 and second gear 5025 to rotate, and is mounted on ratchet 5023a at left and right sides of first gear 5022, lead to
Check pawl 5023b limitation ratchet 5023a is crossed to reversely rotate, and can be by check pawl when ratchet 5023a rotates counterclockwise
5023b allows it to will not influence ratchet 5023a and rotates counterclockwise toward extrapolation, and reset spring 5023c is recycled to allow check pawl
5023b returns to original position, avoids first gear 5022 that gear band 5021 is driven to slide down, passes through first gear 5022 and the second tooth
Support frame 5031 between wheel 5025 allows gear band 5021 to be not pressurised power and be recessed, and utilizes 5032 equipment gear band 5021 of roller bearing
Sliding, the resistance to sliding for reducing gear band 5021 slide L-type control-rod 5023e when luggage case 1 is moved down stair outward
Dynamic, so that L-type control-rod 5023e drives check pawl 5023b to disconnect the connection with ratchet 5023a, ratchet 5023a be can be reversed
Rotation, can glide, and 1 weight of luggage case is bigger, the speed of downslide is faster, very automatically since luggage case 1 is affected by gravity
It is easy the speed for allowing user to lose control of downslide, the resistance ring 5042 in threaded post 5041 is rotated toward 5024 direction of turntable,
So that resistance ring 5042 and turntable 5024 fit, closer second gear 5025 is contacted between resistance ring 5042 and turntable 5024
Resistance is bigger, avoids luggage case 1 from gliding out of control.
Problems solved by the invention is the pull rod locating slot 6 being fastened on luggage case 1 by pull rod 7, convenient for dragging luggage
1 stair activity of case can drag 1 stair climbing of luggage case using walking mechanism 502, save physical strength, pass through unidirectional limiting mechanism
5023 when can be to avoid dragging luggage case 1, and luggage case 1 is slided down by gravity principle, and when luggage case 1 will move down stair, lead to
It crosses speed regulator 504 and controls the speed that luggage case 1 glides, avoid luggage case 1 and slip out of the hand because of gliding too fast.
