These embodiments are not intended to limit the present invention, and structural and functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

Referring to fig. 1 to 6, the drawer assembly 100 of the present invention is applied to a refrigerating apparatus. In the invention, the refrigeration equipment can be a refrigerator or a freezer.

Referring to fig. 1 to 6, the drawer assembly 100 includes a drawer 1, a roller 2 engaged with the drawer 1, a screw 3 for fixing the roller 2 to the drawer 1, and a screw mounting member 200.

As shown in fig. 3 to 6, the screw mounting element 200 includes a main body portion 201 for cooperating with the screw 3. The body 201 is provided with a through hole 202 penetrating in a first direction to pass through the screw 3, an opening 203 provided on one side of the through hole 202, and a locking portion 204 extending in a second direction perpendicular to the first direction and located in the opening 203. One end of the buckling part 204 along the second direction is connected with the inner wall of one side of the opening 203, and the other end is separated from the opening 203 and is elastically arranged in the first direction. The free end of the latch 204 has a protrusion 205 protruding in a first direction.

Referring to fig. 1 to 5, the drawer 1 includes a receiving cavity 10 for receiving the screw mounting member 200 and a positioning hole 11 penetrating the receiving cavity 10. The protrusion 205 of the screw mounting component 200 is elastically locked in the positioning hole 11 in the second direction and exposed outward from the positioning hole 11. The accommodating cavity 10 is arranged at one side of the second direction in an open manner, in this application, the accommodating cavity 10 is arranged at the bottom of the drawer 1 and arranged at a downward opening manner, so that the screw assembling element 200 can be installed or taken out of the accommodating cavity 10.

In the present application, the screw mounting element 200 may be made of a material with elasticity, such as plastic or plastic.

Referring to fig. 1 to 5, the drawer 1 further includes a pair of sidewalls 12 disposed opposite to each other in the first direction, and a through hole 13 through which the receiving screw 3 passes and which penetrates the receiving cavity 10. The receiving cavity 10 is located between the side walls 12. The positioning hole 11 is disposed through one of the sidewalls 12 in the first direction. The through hole 13 corresponds to the through hole 202 of the screw-fitting member 200. In a preferred embodiment of the present application, the diameter of the through hole 13 is greater than the diameter of the screw 3.

Referring to fig. 6, the screw-fitting member 200 has a first portion 206 and a second portion 207 which are continuously arranged in the second direction.
