The bottom surface inclination of guide rail 31 is the same with the inclination of gyro wheel 22 to make the bottom surface of guide rail 31 paste with the top surface of gyro wheel 22 mutually, thereby when making the bottom surface of guide rail 31 and the top surface of gyro wheel 22 mutually slide, can be more stable, reduce the rocking of drawer 3 pull in-process, and then can effectively prevent drawer 3 collision case courage 2 inside control lateral wall at the in-process of pull drawer 3, with the harm that reduces drawer 3, promote the life of drawer 3 and case courage 2, also reduce the noise of drawer 3 pull in-process simultaneously, improve the smoothness of drawer 3 pull, the user experience of reinforcing user.

It should be noted that, in other embodiments, the inclination of the bottom surface of the guide rail 31 and the inclination of the roller 22 may be separately set.

Fig. 12 is a schematic structural view of a drawer 3 in a further embodiment of the present utility model. Fig. 13 is a schematic view of the structure of the mounting fixture 23 of fig. 12. Fig. 14 is a cross-sectional view of N-N of fig. 13.

Referring to fig. 12 to 14, in some embodiments, the bottom surface of the guide rail 31 extends downward to form a rib 312, the rib 312 extends along the front-rear direction of the case 1, the rib 312 is located between the roller 22 and the outer side wall of the drawer 3 corresponding to the roller 22, and the rib 312 is used to abut against the side wall of the roller 22 facing the drawer 3. And when the drawer 3 slides along the front-rear direction of the case 1, the distance between the ribs 312 and the rollers 22 corresponding to the ribs 312 is smaller than the distance between the side edge 33 and the inner side wall of the corresponding case liner 2. Thereby protruding muscle 312 can collide with gyro wheel 22 before side 33 and the inside wall of corresponding case courage 2, and then can effectively prevent the inside left and right sides wall of drawer 3 collision case courage 2 at the in-process of pull drawer 3 to reduce the harm of drawer 3, promote the life of drawer 3 and case courage 2, also reduce the noise of drawer 3 pull in-process simultaneously, improve the smoothness nature of drawer 3 pull, reinforcing user's use experience.

It should be noted that, in other embodiments, when the guide rail 31 is the outermost edge of the outer sidewall of the drawer 3, the spacing between the rib 312 and the roller 22 corresponding to the rib 312 is smaller than the distance between the guide rail 31 and the inner sidewall of the corresponding liner 2.

It should be noted that, in other embodiments, the ribs 312 and the boss 232 may be disposed at the same time, so as to reduce the left-right swing and noise during the drawing process of the drawer 3. The protruding ribs 312 and the boss 232 can be independently arranged, and the limit can be realized in the drawing process of the drawer 3, so that the noise is reduced, the cost is reduced, and the structure is simplified.

It can be seen that, when the fixing seat 23 is provided with the boss 232 on the side wall facing the drawer 3, the roller 22 can be not obliquely arranged and the boss 312 is not provided, the bosses 232 on the left side and the right side can limit the drawer 3, the service lives of the drawer 3 and the box liner 2 are prolonged, meanwhile, the noise in the drawing process of the drawer 3 is reduced, and the use experience of a user is enhanced. Similarly, the ribs 312 and the rollers 22 can be arranged independently, and can limit the drawer 3, so that noise in the drawing process of the drawer 3 is reduced. After the rollers 22 are arranged obliquely downwards, the limiting of the drawer 3 can be realized more firmly by arranging the bosses 232 and/or the ribs 312. The ribs 312 and the boss 232 may be arranged simultaneously, so as to reduce the left-right swing of the drawer 3 during the drawing process and reduce the noise.

As can be seen from the technical scheme, the embodiment of the utility model has at least the following advantages and positive effects:

the refrigerator provided by the utility model can utilize the roller wheels 22 to be arranged on the left and right inner side walls of the refrigerator liner 2, and the bottom surface of the guide rail 31 is slidably supported at the top of the roller wheels 22 so that the drawer 3 can slide along the front and rear direction of the refrigerator body 1; the bosses 232 are respectively arranged on the left and right inner side walls of the tank liner 2 in a protruding way, so that the bosses 232 can limit the drawer 3 between the two bosses 232 in the drawer 3 drawing process, and the swing amplitude of the drawer 3 is reduced; and when drawer 3 slides along the fore-and-aft direction of box 1, interval between boss 232 and the lateral wall of drawer 3 that corresponds is less than the minimum interval between the lateral border of the lateral wall of drawer 3 that corresponds with boss 232 and the inside wall of box courage 2 that corresponds to effectively prevent the inside left and right sides wall of drawer 3 collision box courage 2 at the in-process of pull drawer 3, in order to reduce the harm of drawer 3, promote the life of drawer 3 and box courage 2, also reduce the noise of drawer 3 pull in-process simultaneously, reinforcing user's use experience.

While the utility model has been described with reference to several exemplary embodiments, it is to be understood that the terminology used is intended to be in the nature of words of description and of limitation. As the present utility model may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
