Detailed Description

Referring to fig. 3-6, an underframe structure of a refrigerator is disclosed in an embodiment of the present utility model, including a floor 10 and a bottom beam 30, a PE block 40 is disposed between the floor 10 and the bottom beam 30, the PE block 40 is used for supporting the floor 10, so that a foaming layer 50 is filled between the floor 10 and the bottom beam 30, a reinforcing rib 20 is disposed on a surface of the floor 10 facing the bottom beam 30, and the reinforcing rib 20 is in plug-in fit with the PE block 40. On the basis of the prior art shown in fig. 1-2, in order to improve the process, the utility model cancels the designs of angle iron 60, self-tapping screw 70 and the like, redesigns the reinforcing rib 20 and the PE block 40, and realizes the function of fixing the PE block 40 by the plug-in cooperation of the reinforcing rib 20 and the PE block 40. The reinforcing ribs 20 may be arranged in parallel, as described in the background art, 5-8 reinforcing ribs 20 are generally arranged, so that the number of the reinforcing ribs 20 can be adjusted according to the actual sizes of the floor 10 and the refrigerator, and meanwhile, it is required to ensure that each reinforcing rib 20 is correspondingly provided with one PE block 40. Thus, the strength of the floor panel 10 and the supporting function of the PE block 40 to the floor panel 10 can be sufficiently achieved.

Referring to fig. 4 to 6, in the present embodiment, the reinforcing rib 20 includes a mounting groove 24 and a plugboard 25, one side of the pe block 40 is provided with a groove 41, and the groove 41 is matched with the plugboard 25; when the recess 41 is mated with the insert plate 25, one end of the PE block 40 is mated with the mounting groove 24. Therefore, by arranging the groove 41 on the PE block 40 and utilizing the matching of the groove 41 and the plugboard 25, the PE block 40 can be inserted into the mounting groove 24 of the reinforcing rib 20 along the plugboard 25, so that the PE block 40 and the reinforcing rib 20 are matched in a plugging manner, the PE block 40 and the floor 10 are fixed, and the design of eliminating the angle iron 60 and avoiding the tapping screw 70 is achieved.
