The invention discloses an umbrella rod device, an electric umbrella and a telescopic device. The umbrella rod device comprises an umbrella head, a middle rod and an umbrella rod transmission assembly, the middle rod comprises a plurality of sleeves, an inner sleeve located on the innermost portion and an outer sleeve located on the outermost portion, and one end of the inner sleeve is connected with the umbrella head; the umbrella rod transmission assembly is located in the inner sleeve and comprises a first transmission pipe and a second transmission pipe, the first transmission pipe and the second transmission pipe are telescopically connected in a sleeved mode, the first transmission pipe is rotatably connected with the umbrella head, the first transmission pipe or the second transmission pipe is a threaded round pipe, the inner wall of the threaded round pipe is provided with internal threads, and the outer wall of the threaded round pipe is provided with external threads; the threaded round pipe is formed by extruding the inner wall or the outer wall of the hollow round pipe; and when the first transmission pipe rotates in the first direction, the second transmission pipe can move in the direction away from the umbrella head and can apply a force to the outer sleeve so that the multiple sleeves of the middle rod are pulled open to form a long rod connected end to end. The umbrella rod device has a low requirement on the torsion of the motor, and the production cost can be reduced.
Description
technical field [0001] The invention relates to the field of electric umbrellas, in particular to an umbrella pole device, an electric umbrella and a retractable device. Background technique [0002] After the folding umbrella is folded, the length is small, and it is very easy to carry and store, so it is deeply loved by the majority of users. However, the traditional folding umbrella usually requires the user to use both hands to open or close it. When the user holds an object in one hand and the umbrella in the other, it is not convenient to open or close the folding umbrella conveniently and quickly. In order to open or close folding umbrellas more conveniently and quickly, people have designed electric umbrellas. An electric umbrella usually includes an umbrella pole device and an umbrella rib device, and the umbrella rib device is arranged on the umbrella pole device. When the electric umbrella is opened, the umbrella rod device needs to be extended and the umbrella ...
