There are few trolley luggage bags with wide rods on the market, because the wide rods will make the luggage unbalanced.This problem is related to the structure of the tie rod.
The working principle of the trolley is as follows: it is actually a tube with pistons at both ends, which are the same as those at both ends that can be seen from the outside, and the duct is on the corner There is a piston in the rod of the tube, which is pulled back and forth. When pulling, one side first sucks the wind into the box through the outer valve, and at the same time, the outer valve on the other side closes the inner valve to open the air into the air duct and exits the tube. The two ends change back and forth.
The ordinary drawbar is internally a lever structure. If it is simply widened, it will easily cause instability of the lever structure. When dragging the suitcase, the tie rod is likely to shake.
New structure Drawbar
Our wide tie rod adopt a brand new structure. Use gearwheel to drive the gear bridges and then drive the steel wire to increase the stability of the entire structure.
