Detailed ways

The invention discloses a door ring assembly structure of a washing machine, which comprises a front door ring and a rear door ring which are cooperatingly installed, a plurality of front door ring assembly ribs are arranged inside the front door ring, a plurality of rear door ring assembly ribs are arranged inside the rear door ring, the front door ring assembly ribs and the rear door The ring assembly ribs are correspondingly provided with a number of buckles and slots for mutual assembly, and the front door ring assembly ribs and the rear door ring assembly ribs are interference assembled through the buckles and the slots.

The invention achieves the purpose of assembly through the interference fit between the buckle and the slot, simplifies the assembly process and improves the assembly effect.

In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

Referring to Figures 3 to 5, in a preferred embodiment of the present invention, the washing machine door ring assembly structure includes a front door ring 10 and a rear door ring 20, the front door ring 10 is provided with a front door ring assembly rib 11, and the rear door ring 20 is provided with a The rear door ring assembly rib 21, the front door ring assembly rib 11 is provided with several buckles 111, and the rear door ring assembly rib 21 is correspondingly provided with a plurality of card slots 211, and the front door ring assembly rib 11 and the rear door ring assembly rib 21 pass through the buckle in the present invention. 111 and the card slot 211 for assembly.

In the present invention, the assembly ribs 11 of the front door ring and the assembly ribs 21 of the rear door ring are interference-fitted through the buckle 111 and the slot 211 to prevent poor assembly caused by the oversized rear door ring. Interference assembly is to rely on the amount of interference after the fittings are assembled to achieve a fast connection. After assembly, due to the elastic deformation of the material, pressure is generated between the mating surfaces. Therefore, there is a considerable connection between the mating surfaces of the front door ring and the rear door ring during work. friction to transmit torque, tension or axial force.

Preferably, in this embodiment, the rear door ring assembly rib 21 is arranged approximately perpendicular to the bottom surface of the rear door ring, and there are also several reinforcing ribs 22 intersecting with the rear door ring assembly rib 21 inside the rear door ring.
