Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerators, and particularly relates to a supporting slide rail, a drawer assembly and a refrigerator. Background Art

[0002] In the prior art, most refrigerator drawers are mounted on sliding rails on both sides, and corresponding rail brackets are provided on the inner liner of the refrigerator. The refrigerator drawer slides back and forth on the rail brackets by using the sliding rails on both sides to achieve pulling and pushing. However, when the refrigerator drawer is relatively large, the sliding rails on both sides are difficult to play a reliable supporting role, and during pulling and pushing, there will be defects such as the drawer shaking and the load-bearing capacity of the drawer being insufficient. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a supporting slide rail that can effectively improve the load-bearing capacity of the drawer and the smoothness during pulling and pushing.

[0004] A supporting slide rail includes a rail bracket and a sliding rail that can slide along the rail bracket; the rail bracket is arranged along the depth direction of the inner liner of the refrigerator and is fixed at the middle position of the inner bottom wall of the refrigerator inner liner, and the sliding rail is arranged along the depth direction of the refrigerator drawer and is fixed at the middle position of the outer bottom wall of the refrigerator drawer.

[0005] The second aspect of the utility model provides a drawer assembly using the above-mentioned supporting slide rail.

[0006] A drawer assembly using the above-mentioned supporting slide rail includes a refrigerator drawer arranged on the supporting slide rail.

[0007] The third aspect of the utility model provides a refrigerator using the above-mentioned drawer assembly.

[0008] A refrigerator using the above-mentioned drawer assembly includes a refrigerator cabinet on which the above-mentioned drawer assembly is installed.

[0009] By using the arrangement of the supporting slide rail, the utility model can not only effectively avoid the shaking of the refrigerator drawer during pushing and pulling, but also improve the load-bearing capacity of the refrigerator drawer to a certain extent, and at the same time has the advantages of simple structure and low manufacturing cost.

[0015] See Figure 1 and Figure 2 A support slide rail provided in this embodiment includes a guide rail bracket 1 and a sliding guide rail 2 that can slide along the guide rail bracket 1. The guide rail bracket 1 is arranged along the depth direction of the refrigerator inner liner 3 and is fixed at the middle position of the inner bottom wall of the refrigerator inner liner 3. The sliding guide rail 2 is arranged along the depth direction of the refrigerator drawer 4 and is fixed at the middle position of the outer bottom wall of the refrigerator drawer 4

[0016] During use, under the preconditions of the background technology (slide rail brackets are provided on both sides of the refrigerator drawer and are supported on the guide rail brackets on both sides of the refrigerator inner liner), the above support slide rail is installed at the middle position between the inner bottom wall of the refrigerator inner liner 3 and the outer bottom wall of the refrigerator drawer 4. When pushing and pulling the refrigerator drawer 4, while the refrigerator drawer 4 slides on the slide rail brackets on both sides, the slide rail brackets at the bottom also move synchronously. While improving the sliding sensitivity, the support slide rail at the bottom not only plays a certain supporting role for the refrigerator drawer 4, avoiding shaking during pulling, but also effectively improves the load-bearing capacity of the refrigerator drawer, especially suitable for large-size refrigerator drawers, and a single support slide rail can play the above roles, having the advantage of low manufacturing cost

[0017] In this embodiment, see Figure 3 A guide groove 5 is provided on the side wall of the guide rail bracket 1 along the length direction. The guide groove 5 sequentially includes a buckle area 51 and a sliding area 52 from the direction of the refrigerator drawer 4 to the inner rear wall of the refrigerator inner liner 3. An active catch 53 that can slide in the buckle area 51 and the sliding area 52 is provided in the guide groove 5. See Figure 4 A fork 6 is fixedly provided on the side wall of the sliding guide rail 2. Combining Figure 5 The fork feet of the fork 6 are limited in the corresponding grooves 54 of the active catch 53. See Figure 3 The buckle area 51 is in a slope shape, and its high point is connected to the sliding area 52. A block 56 corresponding to the bottom slot 55 of the active catch 53 is provided at the connection

[0018] The principle is as follows: When the refrigerator drawer 4 is opened, the sliding guide rail 2 is pulled out from the guide rail bracket 1, so that the fork 6 drives the active catch 53 into the buckle area 51 (as Figure 5At the position A shown, the card slot 55 of the movable card hook 53 falls into the slot 57 of the snap zone 51. At this time, it can be ensured that when taking items in the refrigerator drawer 4, the refrigerator drawer 4 will not automatically bounce back. When closing the refrigerator drawer 4, slightly lift it when pushing the refrigerator drawer 4 inward, drive the sliding guide rail 2 to gradually enter the guide rail bracket 1, and the fork 6 drives the movable card hook 53 to disengage from the snap zone 51 and reset after entering the sliding zone 52 (as shown at the position B in Figure 5 ).

[0019] This embodiment also provides a drawer assembly using the above-mentioned support slide rail, including a refrigerator drawer 4 arranged on the support slide rail.

[0020] This embodiment also provides a refrigerator using the above-mentioned drawer assembly, including a refrigerator body equipped with the above-mentioned drawer assembly.

[0021] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
