Compression plate connecting structure of dust-connecting bucket component

Abstract

The invention discloses a compression plate connecting structure of a dust-collecting bucket component, comprising a compression plate, and an upright column which is fixedly connected with one side of the compression plate; a connecting shaft with a polygon hole, which is connected with the lower end of the upright column; a polyhedron gear shaft whose lower end is provided with a gear, which is matchedly connected with the polygon hole of the connecting shaft; a screw, which connects the upright column and the gear shaft; the upper end of the upright column is closed, the inside of the lower end is provided with a thread hole; the middle of the gear shaft is provided with a through hole; the lower end of the connecting shaft is provided with a concave opening, and the part of the lower end of the gear shaft which corresponds to the concave opening forms a convex table, and when the gear shaft is matched with the connecting shaft, the convex table of the gear shaft is matched with the concave opening of the connecting shaft for locating; the screw enters into the upright column through the lower end of the through hole of the gear shaft and is connected with and fastened with the thread hole of the upright hole, and connects the gear shaft and the upright column. The invention leads the air flow to be smooth, and reduces the noise of the air flow, and leads the assembling of the gear shaft and the connecting shaft to be convenient, and greatly saves labor hour.

Description

technical field [0001] The invention belongs to the field of vacuum cleaners, and in particular relates to a compression plate connection structure in a dust bucket assembly that can make the air flow smooth, reduce the air flow noise, and facilitate the assembly of a gear shaft and a connecting shaft. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate a...

Problems solved by technology

[0010] The connection structure of the compression plate in the prior art has the following disadvantages: the stepped hole in the middle of the column is open at the upper end, so it will fall into the dust and affect the operation of the compression plate, and the opening at the upper end will affect the flow direction of the wind, and the air flow is not smooth, resulting in air flow noise

[0011] In addition, when the polyhedral gear shaft is installed into the polygonal hole of the connecting shaft, since their polygons are not equilateral polygons, it is difficult to align the combined orientation of the assembled gear shaft and the connecting shaft, resulting in inconvenient assembly, labor-intensive and time-consuming
