Referring to fig. 3 to 5, it can be understood that the base 100 is connected with the transmission seat 120, the transmission seat 120 is connected with the movable stop lever 130, the pushing block 210 pushes the movable rack 310 through the stop lever 130, and the pushing block 210 can be prevented from directly colliding with the movable rack 310 by using the stop lever 130 to transmit the pushing force, so as to reduce the loss. The push block 210, the transmission seat 120 and the lever 130 constitute a push assembly.
It will be appreciated that the first end surface includes a first inclined surface, the pushing block 210 is provided with a second inclined surface, the first inclined surface and the second inclined surface are arranged in parallel or nearly parallel, and both the first inclined surface and the second inclined surface can abut against the gear lever 130, and in the axial direction of the gear lever 130, the pushing block 210 and the movable rack 310 are staggered from each other and not on one level. When the drawer 200 is pushed in, the first inclined surface and the second inclined surface are simultaneously abutted against the baffle rod 130, the baffle rod 130 is pushed to move from one end of the slideway 121 far away from the movable first spring 311 to one end close to the movable first spring 311, and at the moment, the movable rack 310 is locked by the locking block 350. The slide 121 has an inclined section, the stop lever 130 is located at the entrance of the inclined section, under the action of the second inclined plane, the stop lever 130 enters the inclined section, then the stop lever 130 enters the other side of the slide 121 along the inclined section, the first inclined plane is not contacted with the stop lever 130, a gap is formed, the first spring 311 keeps pushing force on the movable rack 310 due to the compressed state of the first spring 311, and the movable rack 310 is prevented from pushing force on the drawer 200 due to the fact that the pushing stop block 210 is not contacted with the movable rack 310, meanwhile, the influence on the buckling of the drawer 200 and the refrigerator box body is avoided, and the sealing performance is improved. The drawer 200 and the box body are usually in a magnetic attraction or buckling connection mode, and the movable rack 310 cannot prop against the drawer 200, so that the drawer 200 and the box body are connected more firmly, and the tightness is better.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
