[0041] Combine the following Figures 1 to 9 The utility model describes a limit connection structure, a cantilever shelf and a refrigerator.
[0042] It should be noted that the “first direction” mentioned below specifically refers to Figure 1 The left and right directions shown in the figure, the "second direction" mentioned below specifically refers to Figure 2 The up and down direction shown in the figure, the "third direction" mentioned below specifically refers to Figure 1 The front-to-back direction shown in .
[0043] In this embodiment, a cantilever shelf of a refrigerator in which a limiting connection structure is applied is taken as an example. The cantilever shelf includes a first shelf 20 and a second shelf 30 arranged adjacent to each other. When in use, one of the first limiting member 111 and the second limiting member 112 is arranged on the first shelf 20, and the other is arranged on the second shelf 30 (in this embodiment, the first limiting member 111 is arranged on the first shelf 20, and the second limiting member 112 is arranged on the second shelf 30 as an example).
[0044] It should be noted that the position-limiting connection structure 10 provided by the utility model can be applied to the cantilever shelf of the refrigerator and can also be applied to the connection between other components. For example, the position-limiting connection structure provided by the utility model can limit the position of the adjacent first component and the second component in the first direction and the second direction to prevent the first component and the second component from deforming in an "outward eight" or "inward eight" manner, or from deforming in an up-and-down manner.
[0045] See also Figure 1 and Figure 2As shown, the position-limiting connection structure 10 provided by the embodiment of the utility model includes a first position-limiting assembly 110 and a second position-limiting assembly 120. The first position-limiting assembly 110 includes a first position-limiting member 111 and a second position-limiting member 112, a position-limiting groove 1111 is formed on the first position-limiting member 111, and a position-limiting block 1121 is formed on the second position-limiting member 112, and the position-limiting block 1121 cooperates with the position-limiting groove 1111 in a first direction; the second position-limiting assembly 120 includes a first position-limiting protrusion group and a second position-limiting protrusion group that are arranged opposite to each other, the first position-limiting protrusion group includes a plurality of first position-limiting protrusions 121, and the second position-limiting protrusion group includes at least one second position-limiting protrusion 122, and the second position-limiting protrusion 122 cooperates with the first position-limiting protrusion 121 in a second direction.
[0046] When the limiting connection structure 10 provided by the utility model is used, the first limiting member 111 is arranged on the first shelf 20, and the second limiting member 112 is arranged on the second shelf 30. The limiting groove 1111 formed on the first limiting member 111 and the limiting block 1121 formed on the second limiting member 112 are limited in the first direction, and the multiple first limiting protrusions 121 in the first limiting protrusion group and at least one second limiting protrusion 122 in the second limiting protrusion group are limited in the second direction. On the basis of ensuring that the first shelf 20 and the second shelf 30 remain horizontal, it is possible to prevent the first shelf 20 and the second shelf 30 from being deformed into an "outward eight" or "inward eight" shape.
[0047] It should be explained that the above-mentioned "outward eight" specifically refers to the front end of the first shelf 20 and the second shelf 30 expanding outward, resulting in a larger gap between the first shelf 20 and the second shelf 30. The above-mentioned "inward eight" deformation specifically refers to the rear end of the first shelf 20 and the second shelf 30 expanding outward, resulting in a smaller gap between the first shelf 20 and the second shelf 30.
[0048] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, specifically, in this embodiment, a T-shaped limiting groove is formed on the first limiting member 111, and a T-shaped limiting block is formed on the second limiting member 112. The T-shaped limiting block is located in the T-shaped limiting groove, and the T-shaped limiting block and the T-shaped limiting groove are limited in the first direction. When the first shelf 20 and the second shelf 30 are subjected to a lateral external force, the left side wall and / or the right side wall of the T-shaped limiting block abut against the left side wall and / or the right side wall of the T-shaped limiting groove, thereby preventing the first shelf 20 and the second shelf 30 from deforming in an "outward eight" or "inward eight" manner. In specific implementation, the limiting groove 1111 and the limiting block 1121 can also be set to other shapes, which can meet the requirements that the limiting groove 1111 and the limiting block 1121 can limit the movement of the components connected thereto in the first direction when they cooperate.
[0049] The first limiting protrusion group is arranged at the end of the first limiting member 111, and the second limiting protrusion group is arranged on the second shelf 30, so that the first limiting protrusion 121 in the first limiting protrusion group and the second limiting protrusion 122 in the second limiting protrusion group can cooperate with each other. Of course, under the premise of satisfying the spatial layout and the limiting cooperation of the first limiting protrusion 121 and the second limiting protrusion 122 in the second direction, the first limiting protrusion group and the second limiting protrusion group can also be respectively arranged at other set positions, for example, the first limiting protrusion group is arranged on the first limiting member 111, and the second limiting protrusion group is arranged on the second limiting member 112. At this time, a space for arranging the first limiting protrusion group or the second limiting protrusion group can be respectively set on the first limiting member 111 or the second limiting member 112; or the first limiting protrusion group is arranged on the first shelf 20, and the second limiting protrusion group is arranged on the second shelf 30. At this time, a boss extending along the first direction can be arranged on the first shelf 20 and / or the second shelf 30, and the end of the boss is used to set the first limiting protrusion group or the second limiting protrusion group to reduce the distance between the first limiting protrusion group and the second limiting protrusion group, thereby facilitating the first limiting protrusion 121 and the second limiting protrusion 122 to cooperate with each other.
[0050] It can be understood from the above description that in the limiting connection structure 10 provided by the utility model, the first limiting protrusion group and the second limiting protrusion group can be arranged on the first limiting member 111 or the second limiting member 112, and can also be arranged on the components that need to be limitedly connected during specific implementation.
[0051] The first limiting protrusion group includes two first limiting protrusions 121 arranged along the second direction, and the second limiting protrusion group includes a second limiting protrusion 122. The second limiting protrusion 122 is located between the two first limiting protrusions 121, and the upper and lower ends of the second limiting protrusion 122 are respectively abutted against the upper and lower first limiting protrusions 121 to limit the first shelf 20 and the second shelf 30 in the second direction to prevent vertical misalignment and deformation between the first shelf 20 and the second shelf 30.
[0052] It should be noted that, in the present embodiment, every two first limiting protrusions 121 and one second limiting protrusion 122 form a second limiting component 120. In specific implementation, the limiting connection structure 10 may include a single second limiting component 120, or include a plurality of second limiting components 120 spaced apart along a third direction to achieve a better limiting effect.
[0053] In specific implementation, each first limiting protrusion 121 in the first limiting protrusion group can be integrated with the first limiting member 111, and each second limiting protrusion 122 in the second limiting protrusion group can be integrated with the second shelf 30, which can facilitate processing and manufacturing, make the components suitable for mass production, and reduce costs. Of course, each first limiting protrusion 121 in the first limiting protrusion group can be separately provided with the first limiting member 111, and each second limiting protrusion 122 in the second limiting protrusion group can be separately provided with the second shelf 30, and each first limiting protrusion 121 can be connected to the first limiting member 111, and each second limiting protrusion 122 can be connected to the second shelf 30 by plugging, clamping, threading, etc.
[0054] See also Figure 1 and Figure 2 As shown, in this embodiment, the limiting groove 1111 and the limiting block 1121 both extend along the second direction, and the first limiting protrusion 121 and the second limiting protrusion 122 are both cylindrical protrusions, and a guide installation surface in the second direction is formed on the cylindrical protrusion. During installation, the limiting block 1121 can be directly aligned with the limiting groove 1111 and pressed downward. Since the first limiting protrusion 121 and the second limiting protrusion 122 are both cylindrical protrusions, under their guiding effect, the second limiting protrusion 122 is inserted between the two first limiting protrusions 121 arranged along the second direction, and the installation is simple.
[0055] It should be noted that the above cylindrical protrusions can be understood as regular cylindrical protrusions or irregular cylindrical protrusions. Two cylindrical protrusions can be arranged adjacent to each other or at a certain distance.
[0056] See also Figure 1 and Figure 2 As shown, in this embodiment, the limiting block 1121 cooperates with the limiting groove 1111 in the third direction. That is, when the T-shaped limiting block is located in the T-shaped limiting groove, the upper side wall and / or the lower side wall of the T-shaped limiting block abuts against the upper side wall and / or the lower side wall of the T-shaped limiting groove. This prevents the first shelf 20 and the second shelf 30 from being misaligned and deformed in the front-to-back direction, further improving the connection stability of the limiting connection structure 10 provided by the utility model.
[0057] See also Figure 3 and Figure 4 As shown, according to some embodiments of the present utility model, the difference from the above embodiments is that, in this embodiment, the first limiting protrusion group includes two first limiting protrusions 121 arranged along the second direction, and the second limiting protrusion group includes two second limiting protrusions 122 arranged along the second direction, and the first limiting protrusion 121 and the second limiting protrusion 122 cooperate in limiting the position in the second direction (see Figure 4 As shown). The first limiting protrusion 121 and the second limiting protrusion 122 are both spherical protrusions.
[0058] It should be noted that, in the present embodiment, every two first limiting protrusions 121 and one second limiting protrusion 122 form a second limiting component 120. In specific implementation, the limiting connection structure 10 may include a single second limiting component 120, or include multiple second limiting components 120 spaced apart along a third direction to achieve a better limiting effect.
[0059] Compared with the aforementioned embodiment, this embodiment can better limit the first shelf 20 and the second shelf 30, thereby preventing the first shelf 20 and the second shelf 30 from vertically dislocating.
[0060] See also Figure 5 and Figure 6 As shown, according to some embodiments of the utility model, the difference from the aforementioned embodiments is that, in the present embodiment, the first limiting protrusion group includes two first limiting protrusions 121 arranged along the second direction, the second limiting protrusion group includes a second limiting protrusion 122, and the first limiting protrusion 121 is a spherical protrusion, and the second limiting protrusion 122 is a cylindrical protrusion.
[0061] Similarly, in this embodiment, every two first limiting protrusions 121 and one second limiting protrusion 122 form a second limiting component 120. In specific implementation, the limiting connection structure 10 may include a single second limiting component 120, or include multiple second limiting components 120 arranged at intervals along a third direction to achieve a better limiting effect.
[0062] See also Fig. 9 As shown, the cantilever shelf provided by the utility model comprises a first shelf 20, a second shelf 30 and a limiting connection structure 10 as in any of the above embodiments. The second shelf 30 is arranged adjacent to the first shelf 20, and the first shelf 20 and the second shelf 30 are connected by the limiting connection structure 10.
[0063] Specifically, in this embodiment, the first limiting member 111 is disposed on the side wall of the first shelf 20 , and the second limiting member 112 is disposed on the side wall of the second shelf 30 , and the positions of the first limiting member 111 and the second limiting member 112 correspond to each other.
[0064] The cantilever shelf provided by the utility model adopts the above-mentioned limiting connection structure 10 to connect the first shelf 20 and the second shelf 30, so as to prevent the first shelf 20 and the second shelf 30 from "outward eight" and "inward eight" deformation, vertical misalignment deformation, and front and back misalignment deformation, which greatly improves the stability of the cantilever shelf when in use and is simple to assemble.
[0065] According to some embodiments of the utility model, one of the first limiting protrusion group and the second limiting protrusion group is arranged on the first shelf 20 or the second shelf 30, and the other is arranged on the first limiting member 111 or the second limiting member 112. In specific implementation, since there is a certain distance between the first shelf 20 and the second shelf 30, and the first limiting member 111 and the second limiting member 112 are closer to the shelf on the opposite side thereof, by arranging one of the first limiting protrusion group and the second limiting protrusion group on the first shelf 20 or the second shelf 30, and the other on the first limiting member 111 or the second limiting member 112, it is beneficial to reduce the distance between the first limiting protrusion group and the second limiting protrusion group, so that the first limiting protrusion 121 and the second limiting protrusion 122 are more easily limited and matched, without the need to arrange a boss extending along the first direction on the first shelf 20 and / or the second shelf 30, thereby reducing the overall processing difficulty of the cantilever shelf.
[0066] See also Fig. 9 As shown, according to some embodiments of the utility model, the limiting connection structure 10 is arranged at the front end of the first shelf 20 and the second shelf 30. In specific implementation, since the rear ends of the first shelf 20 and the second shelf 30 are connected through other components, by arranging the limiting connection structure 10 at the front end of the first shelf 20 and the second shelf 30, the first shelf 20 and the second shelf 30 can have a better limiting connection effect, thereby improving the stability of the cantilever shelf when in use.
[0067] According to some embodiments of the present invention, the first shelf 20 and the second shelf 30 are connected by a plurality of spaced limiting connection structures 10. The first shelf 20 and the second shelf 30 are connected by a plurality of spaced limiting connection structures 10, which can improve the stability of the cantilever shelf when in use.
[0068] It should be noted that the number and arrangement positions of the limiting connection structures 10 are related to the specifications of the cantilever shelf, which are mainly reflected in the spatial layout and the size of the cantilever shelf in the third direction. For example, under the premise of satisfying the spatial layout, when the size of the cantilever shelf in the third direction is large, multiple limiting connection structures 10 can be set between the first shelf 20 and the second shelf 30 to limit the connection between the two. When the size of the cantilever shelf in the third direction is small, only a single limiting connection structure 10 can be set between the first shelf 20 and the second shelf 30 to limit the connection between the two.
[0069] The utility model provides a position-limiting connection structure 10 as in any one of the above embodiments, or a cantilever shelf as in any one of the above embodiments.
[0070] The refrigerator provided by the utility model adopts the above-mentioned limiting connection structure 10 or cantilever shelf, which can improve the stability of the cantilever shelf when in use, and prevent "outward eight" and "inward eight" deformations, up and down misalignment deformations, and front and back misalignment deformations between the first shelf 20 and the second shelf 30.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
