[0042] Currently, during the transportation of refrigerators, the glass shelves inside the refrigerator often shift due to vibration, and it is easy to damage the inner ribs of the refrigerator or break the glass. To solve this problem, after installing the glass shelves in existing refrigerators, tape and foam parts are usually used to fix the glass shelves. However, this fixing method not only increases the production cost of the refrigerator but also affects the overall aesthetics of the refrigerator.

[0043] Based on this, the present utility model proposes a shelf positioning structure for a refrigerator, aiming to solve the problems of high cost and poor overall aesthetics of the existing fixing method for glass shelves. Among them, Figures 1 to 5 is a schematic structural diagram of the shelf positioning structure provided by the present utility model; Figure 6 is a schematic structural diagram of the existing shelf fixing structure.

[0044] Please refer to Figures 1 to 2 , in an embodiment of the present utility model, the shelf positioning structure 100 includes a box body 1, a shelf 2, and a fixing structure 3. The shelf 2 is arranged inside the box body 1. The fixing structure 3 includes a movable part 32 and a fixing part 31 that cooperate with each other. Among the movable part 32 and the fixing part 31, one is arranged on the shelf 2, and the other is arranged on the box body 1. The movable part 32 is movably installed. During its movement stroke, the movable part 32 has a fixed position and an avoidance position. When in the fixed position, the movable part 32 is combined with the fixing part 31 so that the box body 1 and the shelf 2 are relatively fixed. When in the avoidance position, the movable part 32 is separated from the fixing part 31 to release the restriction on the shelf 2.

[0045] In the technical solution of the present utility model, when it is necessary to fix the shelf 2, the movable part 32 moves to the fixed position so that the movable part 32 is combined with the fixing part 31 to fix the shelf 2 inside the box body 1 to prevent the shelf 2 from moving relative to the box body 1. When it is necessary to take out or place the shelf 2, the movable part 32 moves to the avoidance position so that the movable part 32 is separated from the fixing part 31 to release the fixation of the shelf 2, enabling the shelf 2 to move relative to the box body 1. In this way, through the movement of the movable part 32, the movable part 32 can both cooperate with the fixing part 31 to fix the shelf 2 inside the box body 1, preventing the shelf 2 from shifting during the transportation of the refrigerator, so as to avoid additionally setting a fixing structure 3 to fix the shelf 2, which helps to reduce the fixing cost of the shelf 2, and can also be separated from the fixing part 31 to release the fixation of the shelf 2, enabling the user to take out or place the shelf 2. At the same time, the fixing structure 3 can be hidden inside the box body 1, which helps to improve the appearance effect of the box body 1, thus solving the problems of high cost and poor overall aesthetics of the existing fixing method for the glass shelf 2.

[0046] It should be noted that the shelf 2 of the existing refrigerator is usually fixed to the glass shelf 2 by means of tape and foam fixing parts. Please refer to Figure 6 , a foam fixing part is provided at the opening of the box body 1 of the refrigerator. The foam fixing part is provided with a receiving groove for the shelf 2 to be clamped. In this way, by providing the foam fixing part, the movement of the shelf 2 in the depth direction of the box body 1 is restricted, and the shelf 2 is prevented from shifting when the box body 1 moves. However, in this fixing method, the foam fixing part needs to extend vertically upwards and downwards to abut against the box body 1, so that the size of the foam fixing part is large and the cost is high. Therefore, in the present utility model, through the movement of the movable part 32, the movable part 32 can both cooperate with the fixed part 31 to fix the shelf 2 in the box body 1, preventing the shelf 2 from shifting during the transportation of the refrigerator, so as to avoid additionally providing a fixing structure 3 to fix the shelf 2, which helps to reduce the fixing cost of the shelf 2, and can also be separated from the fixed part 31 to release the fixing of the shelf 2, enabling the user to take and place the shelf 2. At the same time, the fixing structure 3 can be hidden in the box body 1, which helps to improve the appearance effect of the box body 1.

[0047] Since the shelf 2 is restricted by the box body 1, the shelf 2 usually moves in the depth direction of the box body 1 in the box body 1. Therefore, in this embodiment, the box body 1 has inner side walls distributed along its width direction, and the movable part 32 and the fixed part 31 are respectively arranged at the side ends of the shelf 2 and the corresponding inner side walls. In this way, the movable part 32 and the fixed part 31 are arranged along the width direction of the box body 1, so that the arrangement direction of the fixing structure 3 intersects with the movement direction of the shelf 2, which is convenient for arranging the fixing structure 3 and restricting the movement of the shelf 2. Of course, in other embodiments, the movable part 32 and the fixed part 31 can also be arranged along the depth direction of the box body 1. The present utility model does not limit this. However, if the fixing structure 3 is arranged along the depth direction of the box body 1, additional limiting structures, such as a hook limiting structure, etc., need to be provided for the movable part 32 and the fixed part 31 to restrict the movement of the shelf 2 in the depth direction of the box body 1.

[0048] Further, the movable part 32 includes a movable convex part. Correspondingly, the fixed part 31 includes a fixed groove. When the movable part 32 is in the fixed position, the movable convex part penetrates through the fixed groove to position the shelf 2 in the box body 1. When the movable part 32 is in the avoidance position, the movable convex part is separated from the fixed groove, so that the fixing structure 3 releases the fixation of the shelf 2, enabling the shelf 2 to move along the depth direction of the box body 1. In this way, by providing the movable convex part and the fixed groove, the fixing structure 3 can both position the shelf 2 in the box body 1 and release the locking of the shelf 2, enabling the shelf 2 to move along the depth direction of the box body 1, facilitating the user to take and place the shelf 2.

[0049] Further, the movable convex part is linearly movably installed on the shelf 2 along the width direction of the box body 1. In this way, the moving direction of the movable convex part is consistent with the setting direction of the fixing structure 3, so that the movable convex part can movably penetrate through the fixed groove, enabling the movable convex part to cooperate with the fixed groove to position the shelf 2.

[0050] In an embodiment of the present utility model, please refer to Figures 1 to 3 , an installation groove 21 is provided at the side end of the shelf 2, and at least part of the movable convex part is adjustable in position within the installation groove 21. In the fixed position, the movable convex part protrudes from the notch of the installation groove 21 and is inserted into the fixed groove. In the avoidance position, the movable convex part retracts into the installation groove 21 to avoid the fixed groove. In this way, by providing the installation groove 21, it is convenient to accommodate the movable convex part. When it is necessary to fix the shelf 2, the movable convex part is moved to protrude from the installation groove 21, so that the movable convex part can penetrate through the fixed groove. When it is not necessary to fix the shelf 2, the movable convex part can be hidden in the installation groove 21, which can not only release the limitation of the shelf 2 but also make full use of the thickness of the shelf 2 and reduce the space occupied by the fixing structure 3.

[0051] In an embodiment of the present utility model, please refer to 4 and Figure 5 , a positioning structure 4 is further provided between the movable convex part and the shelf 2 to relatively fix the movable convex part and the shelf 2 after the movable convex part moves and adjusts its position. In this way, by providing the positioning structure 4, after the movable convex part is adjusted to the fixed position, the movable convex part can be positioned at the fixed position, preventing the movable convex part from moving in the width direction of the box body 1 to avoid the separation of the movable convex part from the fixed part 31.

[0052] In an embodiment of the present utility model, please refer to Figure 4 andFigure 5 On the side wall of the groove of the installation groove 21, there is a mating hole 22. The mating hole 22 is laterally communicated with the notch of the installation groove 21. The movable convex part includes a main convex part 321 and a mating convex part 322. The main convex part 321 extends along the width direction of the box body 1. The main convex part 321 is used to be inserted into the fixed groove or avoid the fixed groove. The mating convex part 322 is arranged on the main convex part 321 and extends out along the height direction of the box body 1. The mating convex part 322 is arranged in the mating hole 22. The positioning structure 4 is arranged between the mating hole 22 and the mating convex part 322. In this way, by setting the main convex part 321, it is convenient to cooperate with the fixed groove to position the shelf in the box body 1. And by setting the mating convex part 322, it is convenient to set the positioning structure 4 and convenient for the user to operate the movement of the main convex part 321.

[0053] It should be noted that there are various ways to drive the movable convex part to move. In another embodiment, the fixing structure 3 further includes an elastic member arranged between the bottom wall of the installation groove 21 and the movable convex part. In this way, by setting the elastic member, it is convenient to drive the movable convex part to extend out of the installation groove 21, which can not only make the movable convex part maintain in the fixed position, but also contract in the installation groove 21 under the action of external force. However, this method requires precise control of the elastic force of the elastic member. At the same time, when the box body 1 changes, the elastic member also needs to be adjusted, and the versatility is poor. Further, the main convex part 321 and the mating convex part 322 can be integrally formed or separately formed. The present utility model does not limit this.

[0054] In an embodiment of the present utility model, the positioning structure 4 includes a positioning part and a mating part respectively arranged on the outer side surface of the mating convex part 322 and the inner side wall of the mating hole 22. The positioning part and the mating part are arranged in multiple along the width direction of the box body 1. One of the positioning parts is selected to cooperate with the mating parts at different positions. In this way, by setting multiple positioning parts and multiple mating parts, the positioning part can cooperate with the mating parts at different positions to position the movable convex part at different positions of the shelf 2 and prevent the movable convex part from moving in the width direction of the box body 1. Further, among the positioning part and the mating part, one is a positioning protrusion 41 and the other is a mating groove 42. In this way, by setting the positioning protrusion 41 and the mating groove 42, the movable convex part can be positioned on the shelf 2 and the movable convex part can move under the drive of external force. Of course, in other embodiments, the positioning part and the mating part can also be two magnetic attraction parts that are mutually cooperated and magnetically attracted, etc. The present utility model does not limit this.

[0055] In an embodiment of the present utility model, please refer to Figure 5 , the movable convex portion further includes an operating convex portion 323 provided on the mating convex portion 322. The operating convex portion 323 extends out of the mounting groove 21 from the mating hole 22. Thus, by providing the operating convex portion 323, it is used to drive the main body convex portion 321 to move. Further, the operating convex portion 323 extends along the depth direction of the box body 1 to increase the area of the operating convex portion 323, facilitating the user to push the main body convex portion 321.

[0056] It can be understood that there are various connection methods between the operating convex portion 323 and the mating convex portion 322. The operating convex portion 323 and the mating convex portion 322 can be connected by bonding or by welding, etc. The present utility model does not limit this.

[0057] In an embodiment of the present utility model, the mounting groove 21 is provided as a non-rotating groove. Correspondingly, the movable convex portion is provided as a non-rotating convex portion. The non-rotating convex portion is non-rotatably fitted and installed in the non-rotating groove. Thus, by adopting the non-rotating setting, the rotation of the movable convex portion is restricted to prevent relative rotation between the mounting groove 21 and the movable convex portion.

[0058] Further, there are various shapes of the mounting groove 21. For example, the mounting groove 21 can be a circular groove or a rectangular groove, etc. The present utility model does not limit this. Specifically, in this embodiment, the cross-section of the non-rotating groove is square. Correspondingly, the cross-section of the non-rotating convex portion is square. On the one hand, it can prevent relative rotation between the movable convex portion and the mounting groove 21, and on the other hand, it can be adapted to the shape of the shelf 2, which is beneficial to expanding the sizes of the mounting groove 21 and the movable convex portion, thereby helping to improve the fixing effect of the fixing structure 3.

[0059] The setting position of the fixing structure 3 has various options. It can be set on the front side of the box body 1 or on the rear side of the box body 1, etc. The present utility model does not limit this. However, if the fixing structure 3 is set on the front side of the box body 1, it is easy to collide when the user takes and places dishes, which is not conducive to the user taking and placing items. Therefore, in this embodiment, an opening is provided on the front side of the box body 1, and the fixing structure 3 is provided between the rear end of the shelf 2 and the box body 1. Thus, setting the fixing structure 3 on the rear side of the box body 1 not only facilitates the user to take and place items but also can hide the fixing structure 3 in the box body 1, which helps to improve the appearance effect of the box body 1.

[0060] In an embodiment of the present utility model, the fixing structure 3 may be provided with one or multiple, etc. The present utility model does not limit this. Please refer to Figure 1 and Figure 3 , two fixing structures 3 are provided, and the two fixing structures 3 are arranged at intervals along the width direction of the box body 1. In this way, by providing the two fixing structures 3, the two ends of the shelf 2 along the width direction of the box body 1 are simultaneously fixed to the box body 1, thereby helping to improve the fixing effect of the shelf positioning structure 100.

[0061] The present utility model also proposes a refrigerator, which includes a shelf positioning structure 100. The specific structure of the shelf positioning structure 100 refers to the above embodiment. Since this refrigerator adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0062] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the technical concept of the present utility model, or direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
