Detailed ways

As shown in FIG. 1 , the drawer rail device with shelves includes a shelf 1 and a rail frame 2 installed in a refrigerator liner 3 , and each side of the shelf 1 is assembled with a rail frame 2 .

Figures 2 to 4 are structural schematic diagrams of the shelf. The first shelf fastening structure 11 assembled with the guide rail frame 2 is provided on both sides of the lower surface of the shelf 1. The first shelf fastening structure 11 is a plurality of buckles.

Fig. 5 and Fig. 6 are the structural representations of the guide rail frame, the first guide rail fastening structure 21 corresponding to the first layer frame fastening structure 11 of the layer frame 1 is provided on the contact surface where the guide rail frame 2 and the layer frame 1 are assembled, The first guide rail fastening structure 21 is designed as a plurality of draw-in slots, because the self-weight of the guide rail frame 2 itself may cause the draw-in slots to deform or even break, so a reinforced support structure 22 to prevent the draw-in slots from being deformed is designed on both sides of each draw-in slot In addition, the guide rail frame 2 is also designed with the first anti-rotation structure 23 that can prevent the front end of the guide rail frame 2 from rotating due to the force, and the first anti-rotation structure 23 is a groove; For the phenomenon of moving back and forth, the front and rear sides of the contact surface where the guide rail frame 2 and the layer frame 1 are assembled are provided with limiting structures 24; The first positioning structure 25; in addition, a drawer guide rail 26 for the sliding of the drawer is also designed.

Figure 7 is a schematic diagram of the assembly structure of the refrigerator liner for matching the shelf and the guide rail frame. The refrigerator liner 3 is provided with a guide rail support surface 31 for supporting the guide rail frame 2; The second anti-rotation structure 33 assembled by an anti-rotation structure 23, the first anti-rotation structure 23 is a groove, and the second anti-rotation structure 33 is a protrusion assembled with the groove; The first positioning structure 25 of the guide rail frame 2 is assembled with the second positioning structure 35 .

When assembling, the guide rail frame 2 must first be assembled with the layer frame 1. Before installation, the card slots on the guide rail frame 2 correspond to the buckles on both sides of the lower surface of the layer frame 1 one by one, and then the guide rail frame 2 is parallelly installed. The slot on the top is inserted into the buckle of shelf 1.

After the rail frame 2 and the shelf 1 are assembled, hold the shelf and the rail frame assembly with your hands, let the lower bottom surface of the rail frame 2 combine with the rail frame support surface 31 on the refrigerator liner 3, and tilt the shelf Push the guide rail frame assembly to the deepest part of the refrigerator liner 3 until the first anti-rotation structure 23 designed as a groove on the back of the guide rail frame 2 is closely connected with the second anti-rotation structure 33 designed as a bump on the refrigerator liner 3 Cooperate, then put down the shelf and rail frame assembly, now the first positioning structure 25 on the rail frame 2 can cooperate well with the second positioning structure 35 on the refrigerator liner 3, and finally the drawer is passed through the rail frame 2 The drawer guide rail 26 structure is installed in the refrigerator casing.

The invention simplifies the assembly process, improves the production efficiency, and is also convenient for later maintenance.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the specific implementation methods of the present invention can still be Modifications or equivalent replacement of some technical features without departing from the spirit of the technical solution of the present invention shall be covered by the scope of the technical solution claimed in the present invention.
