[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0038] Combination Figures 1 to 8As shown, in some embodiments, a connection structure includes a cabinet opening component 100, an inner tank 200, a snap-on component 140 and a limiting component 150; a first side wall 110 and a second side wall 120 are provided on one side of the cabinet opening component 100, and a slot 130 is defined between the first side wall 110 and the second side wall 120; the edge of the inner tank 200 can be adapted to be inserted into the slot 130; the snap-on component 140 is arranged between the inner wall of the slot 130 and the side wall at the edge of the inner tank 200; the limiting component 150 includes a limiting notch 151 and a limiting claw 152, wherein the limiting notch 151 is arranged on the side of the first side wall 110 and / or the second side wall 120, and the limiting claw 152 is arranged on the side wall at the edge of the inner tank 200, and can be adapted to be inserted into the limiting notch 151.
[0039] By adopting the connection structure provided in the embodiment of the present disclosure, the connection strength between the cabinet opening component 100 and the inner liner 200 is strengthened by the clamping component 140 and the limiting component 150 arranged at the connection between the two. At the same time, the connection point between the inner liner 200 and the cabinet opening component 100 is limited by the cooperation between the limiting notch 151 and the limiting claw 152, so that the inner liner 200 and the cabinet opening component 100 are not easily displaced under the action of external force, so that the connection between the cabinet opening component 100 and the inner liner 200 is more stable, thereby improving the overall service life.
[0040] Optionally, the cabinet opening assembly 100 includes a cabinet opening plane parallel to the cabinet opening, with an opening in the middle of the cabinet opening plane adapted to the access opening of the inner liner 200 for storing items, and the first side wall 110 and the second side wall 120 are arranged on the side of the cabinet opening plane facing the inner liner 200, and are arranged perpendicular to the plane. In this way, the cabinet opening assembly 100 and the inner liner 200 can overlap with each other through the first side wall 110 and the second side wall 120 perpendicular to the cabinet opening plane, making it more convenient to take and put items through the access opening of the inner liner 200.
[0041] Optionally, the first side wall 110 and the second side wall 120 are arranged parallel to each other and are arranged around the opening of the cabinet opening plane. Both are continuous integral structures, or both are discontinuously arranged split structures, or one is a continuous integral structure and the other is a discontinuously arranged split structure. In this way, the various arrangements between the first side wall 110 and the second side wall 120 can be applied to different installation structures of the cabinet opening assembly 100 and the liner 200, so that different arrangements can be selected according to different installation requirements, and the applicability is more flexible.
[0042] It can be understood that the continuous integral structure means that a whole side wall forms a shape identical to the access opening of the liner 200, and the discontinuously arranged split structure means that the same side wall includes multiple segments, and a segment is arranged at a set distance in a form similar to a dotted line, and the multiple segments are all located on the side of the same shape identical to the access opening of the liner 200. For example, when the access opening of the liner 200 is rectangular, the continuous integral structure means that the whole side wall forms a rectangle, and the discontinuously arranged split structure means that the same side wall includes multiple segments, and the multiple segments are arranged at a set distance in a form similar to a dotted line, and the multiple segments are all located on the side of the same rectangle.
[0043] Optionally, there are a plurality of snap-in assemblies 140 disposed in a dispersed manner. Thus, the cabinet opening assembly 100 and the inner liner 200 are fixed at multiple points by the dispersed snap-in assemblies 140, so that the connection between the cabinet opening assembly 100 and the inner liner 200 is more stable.
[0044] Optionally, there are also multiple limiter assemblies 150, which are arranged corresponding to the clamping assemblies 140. In this way, the limiter assemblies 150 can form multiple point limits on the inner liner 200, effectively reducing the displacement of the inner liner 200 under the action of external force, and improving the connection stability between the inner liner 200 and the cabinet opening assembly 100.
[0045] It can be understood that the limiting notch 151 can also play a guiding role. During the plugging process of the inner liner 200 and the cabinet opening assembly 100, the limiting claw 152 and the clamping assembly 140 can accurately enter the corresponding position, effectively reducing the misalignment during the plugging process of the inner liner 200 and the cabinet opening assembly 100.
[0046] Combination Figures 4 to 5 As shown, optionally, the snap-on assembly 140 includes a snap 141 and a slot 142; the snap 141 is provided in plurality, all of which are provided on the first side wall 110; the slot 142 is provided in the same number as the snap 141, and corresponds to the snap 141 one by one, and is provided through the side wall at the edge of the inner liner 200. In this way, during the plugging process of the edge of the inner liner 200 and the cabinet opening assembly 100, the snap 141 gradually moves to the position of the slot 142. When the inner liner 200 and the cabinet opening assembly 100 are fully engaged, the snap 141 is embedded in the slot 142. Without the aid of other tools, the snap 141 is not easy to come out from the slot 142, thereby improving the connection strength between the inner liner 200 and the cabinet opening assembly 100, and making the connection between the inner liner 200 and the cabinet opening assembly stable and reliable.
[0047] Optionally, the buckle 141 is an integral structure with the first side wall 110. In this way, the buckle 141 is integrally formed with the first side wall 110 by stamping or injection molding. There is no joint between the buckle 141 and the first side wall 110. When the buckle 141 is subjected to external force, more pressure can be dispersed to the first side wall 110, so that the buckle 141 is not easily broken due to the external force exceeding its upper limit.
[0048] Combination Figure 5 As shown, optionally, the buckle 141 protrudes toward the second side wall 120, and the side of the buckle 141 surface facing the insertion direction of the inner liner 200 is an inclined surface. The direction of insertion of the buckle 141 toward the inner liner 200 is the starting point of the inclined surface, and it is inclined along the movement direction of the inner liner 200 into the slot 130. In this way, the buckle 141 with the inclined surface is relative to the buckle 141 without the inclined surface, so that during the insertion process, the buckle 141 can be easily embedded in the slot 142 set at the edge of the inner liner 200, and the combination with the slot 142 is completed. The convenience of installation between the inner liner 200 and the cabinet opening assembly 100 is improved.
[0049] Optionally, after the buckle 141 is inserted into the slot 142, the width of the buckle 141 is smaller than the width of the slot 142. In this way, after the buckle 141 is inserted into the slot 142, a certain operating space is still left in the slot 142. During later maintenance, a tool can be inserted into the operating space to pry the buckle 141 out of the slot 142.
[0050] Combination Figure 6 As shown, optionally, the limiting claw 152 is a card structure, and has a set angle with the side wall at the edge of the inner liner 200. In this way, according to the set angle, the limiting claw 152 can form an intersection with the side wall of the limiting notch 151, thereby improving the limiting effect of the limiting notch 151 on the limiting claw 152.
[0051] Optionally, the setting angle between the limiting claw 152 and the side wall of the inner container 200 is between 30° and 90°. In this way, the setting angle within this range can achieve the limiting effect between the limiting claw 152 and the limiting notch 151.
[0052] It can be understood that if the setting angle between the limit claw 152 and the side wall of the inner liner 200 is less than 30°, due to the small setting angle, the cross-contact point between the limit claw 152 and the side wall of the limit notch 151 is lower than or equal to the height of the side wall of the limit notch 151. When the inner liner 200 shifts under the action of external force, the limit claw 152 is easy to break away from the limiting area of the limiting notch 151 and move to the inner side of the limiting notch 151, causing the limiting failure.
[0053] It is understandable that if the angle between the limiting claw 152 and the side wall of the inner tank 200 is set to be greater than 90°, the limiting claw 152 will be higher than the end of the edge of the inner tank 200 facing the cabinet opening assembly 100, occupying the installation space of the cabinet opening assembly 100 and the inner tank 200, making it impossible or difficult for the cabinet opening assembly 100 to close with the edge of the inner tank 200.
[0054] Combination Figure 6 As shown, optionally, the limiting claw 152 can be adapted to have two sides that are in contact with the limiting notch 151, both of which are inclined surfaces. In this way, when the inner liner 200 is displaced under the action of an external force, the limiting claw 152 moves synchronously with the inner liner 200, so that the side of the limiting claw 152 contacts the side of the limiting notch 151. The side of the inclined surface design allows the limiting claw 152 to contact the side wall of the limiting notch 151 during the contact between the limiting claw 152 and the side wall of the limiting notch 151, and the contact point can be offset to one side of the limiting notch 151 through the inclined surface. When the external force disappears, the limiting claw 152 can be reset through the provided inclined surface. When the inner liner 200 is displaced, the limiting claw 152 with an inclined surface reduces the impact of the limiting claw 142 on the side wall of the limiting notch 151, so that the limiting claw 152 or the side wall of the limiting notch 151 is not easy to break, thereby improving the overall service life of the limiting assembly 150.
[0055] It can be understood that when the inner liner 200 is displaced under the action of external force, the limiting claw 152 moves toward one side of the inner liner 200 through the inclined surface of the side edge toward the limiting notch 151, so as to achieve a buffering effect.
[0056] Optionally, the angle of the inclined surface of the two sides of the limiting claw 152 is greater than or equal to 30° and less than or equal to 50°. In this way, when the inner liner 200 is displaced under the action of external force, it can easily shift to the side of the limiting notch 151 within this inclined angle range.
[0057] It is understandable that if the inclination angle of the two side edges of the limiting claw 152 is greater than 50°, when the inner liner 200 is displaced under the action of external force, the limiting claw 152 cannot be smoothly moved to the side of the limiting notch 151, causing the limiting claw 152 to be in hard contact with one side of the limiting notch 151 and be damaged.
[0058] It is understandable that if the inclination angles of the two sides of the limiting claw 152 are less than 30 degrees, when the inner liner 200 is displaced under the action of external force, the limiting claw 152 will easily move to the side of the limiting notch 151, causing the limiting claw 152 to lose its limiting ability.
[0059] Combination Figure 6As shown, the limiting claw 152 and the inner liner 200 are an integrally formed structure, formed by folding the edge of the inner liner 200. In this way, the integrally formed limiting claw 152 improves its structural strength, and when the inner liner 200 is displaced under the action of external force, it is not easy to break, the upper limit of the force of the limiting claw 152 is increased, and the service life of the limiting assembly 150 is increased. At the same time, it is easy to produce and improves production efficiency.
[0060] Optionally, a reinforcing sheet is provided at the folded position at the edge of the inner liner 200. In this way, in order to further enhance the strength of the limiting claw 152 and prevent the limiting claw 152 from being easily broken under the action of external force, a reinforcing sheet is added at the folded position to enhance its strength, thereby further improving the strength of the limiting claw 152.
[0061] Combination Figure 7 As shown, optionally, the position of the limiting notch 151 is set corresponding to the position of the clamping assembly 140, so that the clamping assembly 140 is exposed in the limiting notch 151. In this way, when the cabinet opening assembly 100 or the inner liner 200 needs to be inspected or repaired during subsequent use, the clamping assembly 140 can be observed through the limiting notch 151. At the same time, a certain construction space is provided to facilitate the disassembly operation. On the premise of ensuring the connection strength between the cabinet opening assembly 100 and the inner liner 200, it is also convenient to disassemble and assemble.
[0062] Combination Figure 8 As shown, optionally, the abutment components 160 are dispersedly arranged inside the slot 130, and are located on the first side wall 110 or the second side wall 120. In this way, the abutment components 160 can protrude to the provided surface, and are used to reduce the width of the slot 130. When the liner 200 is plugged into the cabinet opening component 100, the abutment components 160 can perform multi-point compression on one side of the liner 200, so that the side wall of the liner 200 and the cabinet opening component 100 fit closely, increase the contact area between the inner wall of the slot 130 and the side wall of the liner 200, improve the connection strength between the cabinet opening component 100 and the liner 200, and make it difficult for the liner 200 to shift or fall out of the slot 130.
[0063] Optionally, the abutment assembly 160 and the buckle 141 are arranged at the same level. In this way, the abutment assembly 160 and the buckle 141 form a force belt on the side wall of the cabinet opening assembly 100, so that the force points are more concentrated when the inner liner 200 is connected to the cabinet opening assembly 100, thereby improving the connection strength between the inner liner 200 and the cabinet opening assembly 100.
[0064] Optionally, the abutment assembly 160 is arranged between the buckles 141, and at least two abutment assemblies 160 are arranged between every two buckles 141. In this way, the number of abutment assemblies 160 is determined according to the spacing distance between the two buckles 141, so as to avoid the increase of production cost due to excessive arrangement, and at the same time, the fixing force points of the abutment assemblies 160 on the liner 200 can be made more uniform.
[0065] Combination Figure 8 As shown, optionally, the abutment assembly 160 includes a plurality of protrusions arranged at intervals. In this way, the abutment area between the abutment assembly 160 and the side wall of the liner 200 is increased by a plurality of strip structures arranged at intervals. Moreover, these protrusions are in the same direction as the insertion direction of the liner 200 into the slot 130, so that when the liner 200 is inserted, it will not cause the edge of the liner 200 to be stuck, so that the liner 200 can be smoothly inserted into the slot 130.
[0066] Optionally, an inclined surface is provided at one end of the strip structure facing the insertion direction of the liner 200. In this way, the liner 200 can easily enter the slot 130 through the inclined surface during the movement toward the slot 130, thereby improving the convenience of installation.
[0067] Optionally, the length of the strip structure is greater than or equal to four fifths of the depth of the slot 130. In this way, the strip structure can increase the contact area with the side wall of the edge of the inner liner 200 inserted into the slot 130, thereby improving the connection strength between the inner liner 200 and the cabinet opening assembly 100.
[0068] In some embodiments, a freezer includes: any one of the connection structures mentioned above.
[0069] The freezer provided by the embodiment of the present disclosure assembles the connection structure of the above embodiment in the freezer for use, thereby improving the connection strength between the cabinet opening assembly 100 and the inner liner 200 of the freezer, and also limiting the inner liner 200, so that the inner liner 200 is not easily displaced under the action of external force.
[0070] Exemplarily, the connection structure is disposed in a freezer partially equipped with the cabinet opening assembly 100 and the inner tank 200, and the freezer includes but is not limited to a freezer, a refrigerator, a wine cabinet, and a display cabinet.
[0071] Optionally, the cabinet opening assembly 100 further includes a third side wall, and a mounting groove is defined between the third side wall and the second side wall 120. In this way, the edge of the housing of the refrigerator can be embedded in the mounting groove to form a whole with the cabinet opening assembly 100 and the inner container 200.
[0072] Optionally, a plurality of fixing devices are provided on one side of the third side wall facing the second side wall 120. In this way, the housing of the refrigerator can be fixed to the cabinet opening assembly 100 through the fixing devices, thereby improving the connection strength between the housing and the cabinet opening assembly 100.
[0073] Optionally, a heat preservation space is defined between the shell and the inner liner 200. In this way, heat preservation material can be filled into the heat preservation space to improve the heat preservation performance of the refrigerator as a whole.
[0074] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them.
