Description

Technical Field

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

[0002] In the prior art, a simple guide rail applied to a refrigerator, as Figure 1 shown, utilizes the slope from A to B to achieve the self-closing of the drawer. Its disadvantage is that when the force for closing the drawer is small, it is possible that the drawer will stop at A and cannot achieve the self-closing effect. Moreover, due to the setting of the slope, there will be a certain resistance when pulling out the drawer, and the use feeling is poor. 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 resilient plastic guide rail with a self-closing function.

[0004] A resilient plastic guide rail includes a guide rail bracket and a sliding guide rail that can slide along the guide rail bracket; a guide groove is provided on the side wall of the guide rail bracket, and the guide groove sequentially includes a buckle area, a sliding area and a resilient limit area from front to back. A movable catch can slide in the buckle area and the sliding area. A fork is fixedly provided on the sliding guide rail, and the fork feet of the fork are limited in the movable catch. A spring connected to the rear wall of the movable catch is provided in the resilient limit area. The fork can drive the movable catch to be positioned in the buckle area, or can retract to the resilient limit area through the contraction of the spring.

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

[0006] A drawer assembly using the above-mentioned resilient plastic guide rail includes a connecting rod connected between the sliding guide rails, and a refrigerator drawer is mounted on a bracket formed by the connecting rod and the sliding guide rails on both sides.

[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 installed with the above-mentioned drawer assembly.

[0009] By using the fork on the sliding guide rail to drive the movement of the movable catch on the guide rail bracket and then using the spring to drive the reset of the movable catch, the utility model not only enables the drawer to have a self-closing function when closing, but also reduces the resistance during self-closing due to the influence of the spring retraction force, and has a higher use comfort.

[0017] Refer to Figure 2 and Figure 3 , a resilient plastic guide 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 brackets 1 are symmetrically arranged on both sides of the refrigerator inner liner 3, and one end of each is fixed on the inner rear wall of the refrigerator inner liner 3, and the other end extends horizontally towards the front wall of the refrigerator drawer 4. Rollers 4 are provided at both ends of the guide rail bracket 1. The sliding guide rail 2 is mounted on the guide rail bracket 1 and realizes sliding on the guide rail bracket 1 through the rollers 4. The refrigerator drawer 4 is mounted on the sliding guide rail 2. In order to enable the refrigerator drawer 4 to rebound and close automatically when the refrigerator drawer 4 is closed, the technical solution of this embodiment is to refer to Figure 4 , 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, a sliding area 52, and a rebound limiting area 53 from the direction of the refrigerator drawer 4 to the inner rear wall of the refrigerator inner liner 3. Combining Figure 5 , a movable catch 54 that can slide in the buckle area 51 and the sliding area 52 is provided in the guide groove 5. A fork 6 is fixed on the sliding guide rail 2, and the fork feet of the fork 6 are limited in the corresponding grooves 55 of the movable catch 54. Refer to Figure 6 , the buckle area 51 is in a slope shape, and its high point is connected to the sliding area 52. A block 57 corresponding to the bottom slot 56 of the movable catch 54 is provided at the connection. Refer to Figure 5 , the rebound limiting area 53 includes a limiting strip 58 that can abut against the rear part of the movable catch 54. A spring 59 is provided below the limiting strip 58. One end of the spring 59 is connected to the rear wall of the movable catch 54, and the other end is connected to the rear wall of the guide groove 5.

[0018] The principle is: when the refrigerator drawer 4 is opened, the sliding guide rail 2 is pulled away from the guide rail bracket 1, so that the fork 6 drives the movable catch 54 into the buckle area 51 (asFigure 5 At the position C shown, the slot 56 of the movable catch 54 falls into the slot 57 of the catch area 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, driving the sliding guide rail 2 to gradually enter the guide rail bracket 1, and the fork 6 drives the movable catch 54 to disengage from the catch area 51 and enter the sliding area 52 and be limited in front of the rebound limit area 53 (as shown at the position D in Figure 5 shown). When rebounding, since the movable catch 54 is pulled by the spring 59, the resistance during rebounding can be reduced, and the use comfort is relatively high.

[0019] In this embodiment, a cover 7 is adaptively provided on the guide groove 5. The purpose is to improve its aesthetics.

[0020] See Figure 7 , this embodiment also provides a drawer assembly using the above-mentioned rebound plastic guide rail, including a connecting rod 8 connected between the sliding guide rails 2, and the refrigerator drawer 4 is mounted on a bracket composed of the connecting rod 8 and the sliding guide rails 2 on both sides. The purpose is to not only facilitate the assembly of the refrigerator drawer 4, but also prevent the refrigerator drawer 4 from contacting the guide rail bracket 1 and affecting the pulling effect.

[0021] See Figure 8 , this embodiment also provides a refrigerator using the above-mentioned drawer assembly, including a refrigerator body equipped with the above-mentioned drawer assembly.

[0022] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions 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 refinements should also be regarded as the protection scope of the present invention.
