Abstract

A refrigerator door with a replaceable door surface includes a foamed door body and a decorative door plate. A rear side of the decorative door plate is provided with a mater; a front side of the foamed door body is provided with a magnetic lock catch, which comprises a plurality of balls. By clamping the mater on the rear side of the decorative door plate by the plurality of balls of the magnetic lock catch in the foamed door body, the displacement of the decorative door plate in the front-rear direction is limited. In addition, the unlocking magnetic buckle is provided to repel with the magnetic ring, such that a locking relationship between the plurality of balls and the mater is released, thereby achieving the effect of quickly disassembling and installing the decorative door plate.

First claim

What is claimed is:

1. A refrigerator door with a replaceable door surface, comprising:
a foamed door body and a decorative door plate detachably connected to the foamed door body;
wherein a rear side of the decorative door plate is provided with a mater;
a front side of the foamed door body is provided with a magnetic lock catch, which comprises a plurality of balls; and
when the decorative door plate is assembled on the front side of the foamed door body, the mater is inserted in the magnetic lock catch, and the plurality of balls clamps the mater to limit a displacement of the decorative door plate in a front-rear direction;
wherein the magnetic lock catch further comprises a housing and a holding frame, which is assembled inside the housing; the holding frame comprises an axial through hole and a plurality of radial through holes, and the axial through hole and the plurality of radial through holes are opened at the holding frame to respectively provide spatial access to an internal space within the holding frame; the plurality of balls is respectively accommodated in the plurality of radial through holes; and wherein the mater is inserted in the axial through hole, and a side wall inside the housing limits a displacement of the plurality of balls in a vertical direction, such that the plurality of balls clamps the mater;
wherein the magnetic lock catch further comprises a magnetic ring and an elastic member; the magnetic ring is disposed on a front end of the holding frame; and the elastic member is disposed on a rear end of the holding frame;
wherein the magnetic lock catch further comprises an unlocking magnetic buckle, the unlocking magnetic buckle comprising a first permanent magnet having a first magnetic polarity, and the magnetic ring comprising a second permanent magnet having a second magnetic polarity that has a same magnetic polarity as the first magnetic polarity; when the unlocking magnetic buckle is positioned adjacent to the magnetic ring within a repulsive magnetic interaction range, the magnetic ring is repelled by the unlocking magnetic buckle, the magnetic ring compresses the elastic member and moves backwards axially, and the plurality of balls is moved out of the plurality of radial through holes, such that the clamping between the plurality of balls and the mater is released.

2. The refrigerator door with the replaceable door surface according to claim 1 , wherein when the unlocking magnetic buckle is away from the magnetic ring, the compressed elastic member is restored, the holding frame moves forwards axially, and the plurality of balls falls in the plurality of radial through holes.

3. The refrigerator door with the replaceable door surface according to claim 2 , wherein the housing comprises a front cover, which comprises a front panel and an extension portion, the extension portion being located on a rear side of the front panel and protruding outwards, and the front panel being provided with a cross hole; the extension portion has an accommodation cavity; the cross hole is communicated with the accommodation cavity; the magnetic ring, the holding frame, the plurality of balls, and the elastic member are disposed in the accommodation cavity in sequence; and wherein the magnetic ring is located on a front end of the accommodation cavity and close to the front panel.

4. The refrigerator door with the replaceable door surface according to claim 3 , wherein the housing further comprises a rear cover; the front cover is engaged with a front side of the rear cover; the rear cover has an assembly cavity; the extension portion is inserted in the assembly cavity; and a rear end of the extension portion faces a rear wall of the assembly cavity.

5. The refrigerator door with the replaceable door surface according to claim 4 , wherein the elastic member is disposed between the holding frame and the rear wall of the assembly cavity.

6. The refrigerator door with the replaceable door surface according to claim 4 , wherein when the mater is inserted in the cross hole, the magnetic ring, and the axial through hole of the holding frame, the plurality of balls clamps the mater, and an inner wall of the extension portion limits the displacement of the plurality of balls in the vertical direction.

7. The refrigerator door with the replaceable door surface according to claim 1 , wherein the mater is a hanging pin disposed on the rear side of the decorative door plate; and the hanging pin comprises a recess, in which the plurality of balls is clamped.
