For brevity, fig. 1 is a view of hiding components such as a door body and a refrigeration system which are not directly related to the utility model, and for this embodiment, reference may be made to any conventional method.

The refrigerator 100 includes a case 10, and the case 10 is generally composed of a housing, a liner disposed inside the housing, and a heat insulating material formed between the housing and the liner. Referring to fig. 1, the case 10 has an inner space 20, a storage unit 30 for storing articles is provided in the inner space 20, the storage unit 30 is drawable outside the case 10 with respect to the case 10, and the storage unit 30 is provided inside the case 10 through a rail assembly 40. In the illustrative embodiment of fig. 1, the rail assembly 40 includes a rail body 41 secured within the case 10, with a first side 48 of the rail body 41 configured with a slide channel 32 for sliding the storage unit 30.

Referring to fig. 1, in a preferred embodiment, rail assemblies 40 are provided in pairs in the interior space 20, for example, one rail body 41 is connected to the inner wall 11 of the case 10, and the other rail body 41 is connected to the partition wall 12 inside the case 10. The inner wall 11 and the partition wall 12 of the case 10 are further integrally formed with a rail 13, and the rail assembly 40 is disposed above the rail 13 and near the rail 13, so that the inner space 20 of the refrigerator 100 can be advantageously utilized.

In a preferred embodiment, rail assembly 40 is injection molded integrally. The rail body 41 is provided with a mounting hole 43, and the fastener 50 mounts the rail body 41 in the case 10 through the mounting hole 43.

As shown in fig. 1 to 4, the slideway 42 extends between the front and rear ends of the rail main body 41 in the box depth direction Z. The first end 421 of the slideway 42, which is close to the opening direction of the box body, is provided with a first protruding part 44 protruding from the surface of the slideway 42, and the first protruding part 44 extends in the height direction of the slideway 42. The storage unit is favorable for resisting the storage unit from the beginning of the movement of the storage unit, and is favorable for avoiding obvious noise possibly caused by high-intensity friction between the storage unit and the surface of the slideway.

In a preferred embodiment, the first protrusion 44 extends along the height of the slideway 42. Thereby, the instantaneity of the friction generated between the first protrusion and the storage unit is facilitated.

In a preferred embodiment, the rail body 41 includes a rail cross rib 47 extending in the depth direction Z of the case, and the first protrusion 44 protrudes more from the surface of the rail 42 than the rail cross rib 47.

Referring to fig. 5 to 7, the storage unit 30 includes a rail rib 31 engaged with the slide 42, and the rail rib 31 extends in the depth direction Z of the case. The guide rail 31 is positioned in the slideway 42 to facilitate the reciprocating movement of the storage unit 30.

The storage unit 30 further includes a roller 34 disposed at a rear end of the rail 31, and a plane of the outermost side of the roller 34 is closer to the rail assembly 40 than a plane of the outermost side of the rail 31. Thus, when the storage unit 30 is pulled out, the guide rail rib 31 is engaged with the first protrusion 44, and the roller 34 is engaged with the slide rail cross rib 47. The friction between the storage unit and the slideway is reduced in the whole movement process of the storage unit, and the influence on the movement fluency of the storage unit is effectively reduced.

In a preferred embodiment, the distance 0<a between the plane of the outermost side of the roller 34 and the plane of the outermost side of the first protrusion 44 is less than or equal to 1.5mm. In the art, under the condition that the width of the container has a certain tolerance, by limiting the distance between the first protrusion 44 and the roller 34, the container can be conveniently installed only at the first end of the slideway to overcome the instant installation obstruction under the condition that the size of the formed container is unfavorable for the installation of the storage unit, and the possibility of larger noise generated in the movement process of the storage unit is more favorable to be reduced.

"substantially" herein refers to the allowable manufacturing tolerances. Therefore, when the storage unit moves, the gap between the front end of the storage unit and the first end of the slideway and the gap between the rear end of the drawer and the slideway are basically equal, so that the drawer movement direction is guided, and the possibility of loud noise generated in the movement process of the storage unit is further reduced.

Referring to fig. 2, the first end 421 of the slideway 42 is further provided with a guide surface 49, and the first projection 44 is provided immediately behind the guide surface 49. The guide surface 49 gradually slopes in the direction of the box depth direction Z toward the storage unit 30. The guide surface 49 thereby increases the entrance to the ramp, further facilitating the mounting or dismounting of the storage unit.

Referring to fig. 2, the first end 421 of the slideway 42 is further provided with a limit boss 422 for limiting the pull-out position of the storage unit 30, and the first protrusion 44 extends from the top end of the limit boss 422 at least above the slideway transverse bar 47 of the storage unit 30 along the height direction Y of the refrigerator.

Referring to fig. 2, the guide rail body 41 is provided with a mounting hole 43, and a second protrusion 45 is provided at a rear side edge of the mounting hole 43 along the depth Z direction of the box, and the second protrusion 45 protrudes from a periphery of the mounting hole. As such, when the storage unit is pulled out, the second protrusion 45 blocks part of the sound waves and the air flow traveling straight, which is advantageous in reducing the possibility that sound or air flow generated due to the movement of the storage drawer forms a sound amplification in the mounting hole.

As in the preferred embodiment of fig. 2, the number of the mounting holes 43 may be two, and the second protrusions 45 are located at the rear periphery of the mounting holes 43 at the front side, respectively at the front and rear sides of the rail main body 41. Thus, the first protrusion 44 and the second protrusion 45 are both located at the first end 421 of the slideway 42, which is beneficial to the smoothness of the drawing of the storage unit.

In a preferred embodiment as shown in fig. 2, the first end 421 of the rail body 41 is provided with a rail roller 46 at a side near the storage unit 30, and the rail roller 46 is located under the rail rib 31. For improving the smoothness of the movement of the storage unit 30.

The rear end of the guide rail rib 31 is provided with a limit concave part 35 matched with the slideway roller 46, which is further beneficial to defining the pulling-out limit position of the storage unit 30.

In a preferred embodiment, the second protrusion 45 is the same vertical height as the first protrusion 44 protruding from the surface of the slideway 42. In this way, it is advantageous to have the drawer guided more accurately on the side of the slide 42.

Referring to fig. 5 to 7, the rail rib 31 includes a rail cross rib 32 extending in the depth direction Z of the case and a rail vertical rib 33 extending in the height direction Y of the case, and a plane in which an outermost side of the rail cross rib 32 is located is closer to the slide 42 than a plane in which an outermost side of the rail vertical rib is located. Therefore, when the storage unit 30 is pulled out or pushed in, noise generated by friction between the guide rail vertical ribs and the periphery of the mounting hole is reduced.

Referring to fig. 7, the first protrusion 30 extends in the height direction of the slideway 42 to at least exceed the orthographic projection of the corresponding rail bar 31 on the slideway 30. Thus, the stability of the movement process of the storage unit is facilitated.

In another embodiment of the present application, the first protrusion 44 is formed as a roller rotatably mounted to the first end 421 of the slideway 42. In this way, it is further advantageous for improving the smoothness of the movement of the storage unit 30. In particular, the roller may be selected to be a metal roller.
