This utility model involves a telescopic tube structure of an umbrella rib, comprising an outer tube and an inner tube of the long rib, and the left end of the inner tube of the long rib is flexibly seated inside the outer tube of the long rib, the inner tube of the long rib is connected to a locking pin, the outer tube of the long rib is equipped with corresponding grooves, and the inner tube of the long rib is fixed to the outer tube of the long rib when the locking pin is inserted into the groove; when the locking pin detaches from the groove, the inner tube of the long rib will move axially back and forth with respect to the outer tube of the long rib. The inner tube of the long rib is further provided with wedges, and the beveled side of the wedge matches the beveled side of the locking pin. The structure of a telescopic tube structure of an umbrella rib is adopted, which is structurally simple. The wedge with the beveled side pushes the locking pin that also has a beveled side, allowing the locking pin to detach or insert into the groove. It is very convenient to use, wherein the inner tube of the long rib remains flexibly connected when the movable block is pushed to the left, and the release of the movable block allows the inner tube and outer tube of the long rib to remain securely fixed to one another and reliably locked. The number of grooves and the distance between grooves can be adjusted to suit different needs. |
