Embodiment 1

[0036] Such as Figure 1-3As shown, the connection structure between the motor and the wind wheel provided by this embodiment includes a rotating shaft 21 and a connecting piece 11 for transmission, the rotating shaft 21 is suitable for connecting with the motor 2, the connecting piece 11 is suitable for connecting with the wind wheel 1, and The side wall of the connector 11 is molded with a notch 12 extending radially into the interior of the connector 11 and passing through the end wall on one side of the rotating shaft 21 in the axial direction. The 12 places radially move in or out of the connecting piece 11, and the setting of the gap 12 on the connecting piece 11 makes the installation of the wind wheel 1 not affected by the size of the axial installation space during the assembly process of the motor 2 and the wind wheel 1. There is no need to extend into the installation space obliquely from top to bottom, but can be sleeved on the rotating shaft 21 through the connect...

Abstract

The invention relates to the technical field of assembly of tower fans, and particularly to a connecting structure of a motor and a wind wheel and a tower fan comprising the same. The connecting structure comprises a rotating shaft connected with any one of the motor and the wind wheel and a connecting piece connected with the other of the motor and the wine wheel, wherein a notch is formed in the side wall of the connecting piece in a manner of penetrating through the connecting piece in the radial and axial directions and at the position close to the end wall of one side of the rotating shaft; the notch is matched with the rotating shaft in shape and allows the rotating shaft to radially move in or out of the connecting piece through the notch; and the rotating shaft is in transmission fit with the connecting piece. According to the connecting structure of the motor and the wind wheel and the tower fan comprising the same provided by the invention, the needed axial installation space is small, the assembly is quick and convenient, and the size of the overall tower fan is reduced.

Description

technical field [0001] The invention relates to the technical field of tower fan assembly, in particular to a connection structure between a motor and a wind wheel and a tower fan with the structure. Background technique [0002] Currently on the market, the casing of the tower fan is formed with an installation cavity suitable for installing the wind wheel. One end of the installation cavity is provided with a bearing seat that provides support for the rotor shaft, and the other end is provided with a motor. The wind wheel is located between the bearing seat and the motor. In between, when installing the wind rotor, first set the shaft sleeve at the end of the wind rotor on the output shaft of the motor from top to bottom, and use the positioning pin to pass through the corresponding positioning holes on the shaft sleeve and the output shaft. The shaft sleeve and the output shaft are fixed, and then the rotating shaft at the other end of the wind wheel is rotatably fixed in...
