Abstract

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, the plurality of sleeves can be pulled open to form a long rod connected end to end, the sleeve, located in the innermost, of the middle rod is an inner sleeve, the sleeve, located in the outmost, of the middle rod is an outer sleeve, and one end of the inner sleeve is connected with the umbrella head; the umbrella rod transmission assembly is located in the inner sleeve, the umbrella rod transmission assembly comprises a first transmission pipe and a second transmission pipe, the first transmission pipe and the second transmission pipe are telescopically connected in a sleeving mode, one end of the first transmission pipe is rotatably connected with the umbrella head, and one of the first transmission pipe and the second transmission pipeis a rectangular spring; 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 force to theouter sleeve, so that the multiple sleeves of the middle rod are pulled open to form the long rod connected end to end. The umbrella rod device has low requirement on the torsion of a motor.

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 ...
