The rope reel set is used to wind an umbrella rope, and extends into an umbrella tray assembly along the pull rod, so as to realize opening and closing of the umbrella tray assembly. The handle base is hingedly fitted with the armrest shell, the armrest shell is located at an inner side of the umbrella column and is provided for fitting with the chute in an inner side wall of the umbrella column; and the armrest shell is vertically movably positioned along the chute.
Preferably, the rope reel set is provided with a first rope guide roller and a second rope guide roller, the first rope guide roller and the second rope guide roller are located at or near both ends of the pull rod, and the umbrella rope extends from the rope reel set to the first rope guide roller and the second rope guide roller sequentially, and extends outward into the umbrella tray assembly through an umbrella rope outlet.
Preferably, the umbrella rope extends along an inner cavity of the pull rod to the umbrella tray assembly.
Preferably, rope holes are provided above both ends of the pull rod, and a rope slot is provided at a top portion of the pull rod. After the umbrella rope passes through the rope holes, the umbrella rope extends through the rope slot to an end rope hole connected to the umbrella tray, and extends into the umbrella tray assembly through the second rope guide roller.
Preferably, an end portion of the pull rod is embedded into an inner end of the pull rod receiving end, and is fixedly mounted by a bolt piece. The first rope guide roller is rotatably mounted on the bolt piece.
Preferably, an end portion of the pull rod is provided with a rope guide roller end seat, and a bolt piece and the second rope guide roller pass through the rope guide roller end seat.
Preferably, an inner end of the rope reel mounting end is provided with a rope reel, and the rope reel is connected to the armrest shell through a rotating shaft.
Preferably, the armrest shell is provided with a trigger, and a lower end of the trigger is provided with a thimble for fitting.
Preferably, an upper end of the trigger is provided with a clamping piece, and the clamping piece is connected to the fixing pin provided on the armrest shell.
Compared with the prior art, the present invention has the following advantages.
With the armrest shell of the present invention, after the umbrella body is opened, the position of the armrest shell can be adjusted under the umbrella cover, and the angle of the umbrella cover of the umbrella can be adjusted by moving the armrest shell up and down. By pressing the trigger, the umbrella can be locked or unlocked quickly, which is convenient for the adjustment of the armrest shell.
