Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

The utility model discloses a tower fan includes chassis subassembly and fuselage. As shown in fig. 1 and 2, the chassis assembly includes a chassis body 1 and a base 2. The base 2 is provided with a mounting position, so that the base 2 is mounted on the machine body, and the chassis body 1 is mounted on the base 2, thereby forming a main structure of the tower fan. The chassis body 1 can be of an integrated structure or a split structure. If the chassis body 1 is of an integrated structure, a user can directly connect the chassis body 1 with the base 2; if the chassis body 1 is a split structure, a user needs to combine the split chassis body 1 into a whole and then connect the same with the base 2, or connect the chassis body 1 with the base 2 and then connect the chassis body 1 into a whole.

As shown in fig. 3 and 4, the chassis body 1 is provided with a clearance groove 3 and a positioning groove 4 which are communicated with each other, and as shown in fig. 5, a rotary buckle 21 is formed at the bottom of the base 2; the turn buckle 21 is inserted into the clearance groove 3, and is rotated to enter the positioning groove 4 along the clearance groove 3, and the turn buckle 21 is clamped with the positioning groove 4, so that the base 2 and the chassis body 1 are fixed in the axial direction and the radial direction. The clearance groove 3 is internally provided with an elastic buckle 11, and when the rotating buckle 21 is inserted into the clearance groove 3, the elastic buckle 11 elastically deforms and leaves the inlet of the positioning groove 4; when the turn buckle 21 is caught in the positioning groove 4, the elastic buckle 11 is restored and blocks the entrance of the positioning groove 4, so that the base 2 and the chassis body 1 are fixed in the circumferential direction.

And the one end that the bullet detains 11 and is close to the constant head tank 4 entry is the free end, keeps away from the one end and the chassis body 1 integrated into one piece of entry, and is close to the one side of keeping away empty groove 3 and constant head tank 4 intercommunication and be the press surface, and through the press surface atress, the bullet detains 11 and takes place elastic deformation, realizes above-mentioned function.

In order to ensure that the chassis body 1 and the base 2 are firmly connected, the clearance grooves 3 and the positioning grooves 4 are at least arranged in two groups and are arranged along the central circumference of the base 2 body in an array mode.

The rotary buckle 21 is arranged according to the shapes of the clearance groove 3 and the positioning groove 4 and comprises a vertical plate 211 and a transverse plate 212, the vertical plate 211 is vertically and fixedly connected to the bottom surface of the base 2, and one end of the transverse plate 212 is fixedly connected with the vertical plate 211. The vertical plate 211 is gradually narrowed from top to bottom, and the edges of the clearance groove 3 and the positioning groove 4 are also formed with inclined surfaces, thereby ensuring the fixation in the axial direction.

In addition, the chassis body 1 is also provided with a limiting groove 5, the bottom surface of the base 2 is also provided with a limiting column 22, the limiting column 22 is inserted into the limiting groove 5, and when the rotating buckle 21 is inserted into the clearance groove 3, the limiting column 22 is abutted against one end of the limiting groove 5; when the turn buckle 21 is clamped into the positioning slot 4, the limiting column 22 is abutted against the other end of the limiting slot 5.

When the user needs to detach the chassis component, the user only needs to press the elastic buckle 11 from the pressing surface to separate the elastic buckle 11 from the side wall of the rotary buckle 21, and the rotary buckle 21 is not limited by the elastic buckle 11 and can be reversely rotated out, so that the chassis and the base 2 are detached.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention.
