Clip-shaped pin fixed structure of caster wheel for dust collectors

Abstract

The invention discloses a clip-shaped pin fixed structure of a caster wheel for dust collectors, which belongs to an auxiliary instrument of a caster wheel for dust collectors. The clip-shaped pin fixed structure comprises a rotating shaft, the rotating shaft is arranged in a shaft hub of the caster wheel for dust collectors, the external lateral end of the rotating shaft is provided with a concentric shaft gear, and a ring groove is formed at the internal lateral end of the rotating shaft; the internal lateral end of the rotating shaft and the ring groove are arranged in a rotating-shaft hole frame of a base; a perforating part passing through a shaft center is arranged on the ring groove; and the insides of the ring groove and the perforating part are respectively bonded with an elastic integral clip-shaped pin. In the invention designed as above, because a perforating part passing through a shaft center is arranged on the ring groove at the internal lateral end of the rotating shaft, and an arc clip part of the clip-shaped pin is embedded in the ring groove by pinning a pin body part of the clip-shaped pin into the perforating part, so that the clip-shaped pin is installed easily and fixed firmly and stably. Therefore, an action that the caster wheel moves to the ring groove end of the rotating shaft is limited, and an action that the rotating shaft and the caster wheel on the rotating shaft drop from the rotating-shaft hole frame of the base is prevented.

Description

technical field [0001] The invention relates to an auxiliary device for a caster wheel of a vacuum cleaner, in particular to a clamp spring fixing structure for a caster wheel of a vertical vacuum cleaner. Background technique [0002] Vacuum cleaners are a kind of cleaning and hygiene household appliances, which are used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] According to the classification of vacuum cleaners, they can be divided into vertical vacuum cleaners, horizontal vacuum cleaners (tank type) and portable vacuum cleaners. [0004] The structure of the vacuum cleaner generally includes the vacuum cleaner motor that generates negative pressure suction after the power is introduced, the suction nozzle that forms the air duct system, the vacuum tube, the vacuum hose, the dust collection device that filters and collects the suction, and the casters at the bottom of the body. Wait. [0005] Generally speaking, the gas co...
