Referring to fig. 5-6, fig. 5 is a schematic structural diagram of a shaft body according to an embodiment of the present utility model, and fig. 6 is an exploded view of the shaft body according to an embodiment of the present utility model. The shaft 330 further includes a first stop 334 and a second stop 335.

The second portion 333 includes a first end near the screw portion 332, and the first limiting member 334 is disposed at the first end. Referring to fig. 6, the first end of the second portion 333 is provided with a ring of grooves 336 formed along the circumferential direction of the shaft 330, for example. The first stopper 334 includes a first engaging portion 3341, an elastic portion 3342, and a second engaging portion 3343 connected in sequence. The first clamping portion 3341 is partially clamped to the first portion of the groove 336, the second clamping portion 3343 is partially clamped to the second portion of the groove 336, the first portion of the groove 336 is opposite to the second portion of the groove 336, and the elastic portion 3342 deforms when being stressed and recovers deformation when not being stressed. The portion of the first limiting member 334 located outside the recess 336 is used for limiting. The first limiting member 334 is, for example, U-shaped or has an O-shape with a notch. The shape presented by the inner ring side wall of the first limiting member 334 is matched with the shape presented by the bottom wall of the groove 336, i.e. the inner ring side wall of the first limiting member 334 abuts against the bottom wall of the groove 336. The first limiting member 334 is made of plastic or metal, for example.

In other embodiments, the first limiting member 334 may be a ring-shaped elastic member including an inner ring portion and an outer ring portion connected to each other. Wherein, the inner ring part is clamped in the groove 336, and the outer ring part is used for limiting. In this embodiment, the first limiting member 334 is made of silica gel, for example.

The first portion 331 includes a second end proximate to the threaded portion 332, and the second stop 335 is disposed at the second end. The second limiting member 335 has a polygonal cross section in the diameter direction of the shaft body 330.

It can be appreciated that the first distance L1 between the first limiting member 334 and the second limiting member 335 is greater than the second distance L2 between the fourth outer wall 323 and the fifth outer wall 324, so that the shaft 330 can have a certain adjustment stroke, otherwise, the shaft 330 cannot move relative to the nut 320, and the refrigerator door cannot be adjusted.

In some embodiments, the second limiting member 335 is further multiplexed to support the first door 21. It can be appreciated that, during the process of rotating the shaft 330 to move toward the first direction Z1, there is a space between the second limiting member 335 and the nut 320, i.e. the second limiting member 335 is in a suspended state. Because the second limiting part 335 is also used for supporting the door body, the second limiting part 335 is in a suspended state, so that the second limiting part is subjected to larger weight, and the second limiting part 335 is easy to damage due to the pressure caused by the repeated opening and closing of the door body. Based on this, the present utility model provides an embodiment in which the door hinge assembly further includes a reinforcing rib (not shown) detachably installed between the second stopper 335 and the hinge plate 310. The reinforcing ribs can be in a sheet shape, the number of the reinforcing ribs can be multiple, and the reinforcing ribs can be made of plastics, silica gel or metal.

In the actual assembly process of the door hinge assembly 30 provided by the embodiment of the utility model, the nut 320 is first installed in the through hole 311, and the protruding portion 322 of the nut 320 is clamped in the limiting groove 314. Subsequently, the shaft body 330 is screwed with the nut 320, and then the first stopper 334 is mounted in the groove 336 on the first end of the second portion 333, that is, the assembly is completed.

In practice, when the installer/user needs to adjust the height of the refrigerator door, the first door 21 can be lifted slightly, the outer sidewall of the second stopper 335 can be gripped by a tool such as a wrench, and then rotated to adjust the height of the shaft 330 with respect to the nut 320. The shaft 330 does not fall off the nut 320 under the blocking action of the first limiting member 334 and the second limiting member 335. When the first door body 21 is put down, the door body height is adjusted along with the height change of the shaft body 330, so that the problem of unequal heights of the refrigerator door bodies can be solved.

According to the door hinge assembly 30 of the refrigerator and the refrigerator 1 provided by the embodiment of the utility model, the height of the refrigerator door body can be adjusted through the screw connection part 332 of the rotating shaft body 330, the operation is convenient, and the complexity of the hinge plate process is reduced by installing the nut 320 on the hinge plate 310.
