[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that the terms "vertical", "horizontal", "above", "below", "upper side", "top surface" and "bottom surface" are all based on the corresponding view or the orientation in which the refrigerator is placed when it is in normal use.

[0035] Please see Figures 1-4 This utility model provides a refrigerator storage box, which includes a box body 1, a box door 2 and a locking mechanism 3. The box body 1 has at least one storage cavity 11.

[0036] One side of the box door 2 is hinged to the box body 1 via a hinge mechanism 4. The box door 2 has a fixing hole 21 and a through hole 22. The box door 2 can seal at least one storage cavity 11.

[0037] The other side of the box door 2 can be connected to the box body 1 through the locking mechanism 3. The locking mechanism 3 includes a locking pin 31, a locking rod 32 and a locking bolt 33. The locking pin 31 is installed on the box body 1 and can pass through the through hole 22. The locking pin 31 has a locking hole 311. The locking rod 32 is installed on the box door 2 through the fixing hole 21 and can rotate around the hole axis of the fixing hole 21. The locking bolt 33 is installed on the locking rod 32 and can extend into the locking hole 311.

[0038] Specifically, when the bolt 33 is not inserted into the locking hole 311 and the locking pin 31 is not inserted into the through hole 22, the box door 2 is opened; when the bolt 33 is inserted into the locking hole 311 and the locking pin 31 is inserted into the through hole 22, the box door 2 is locked to the box body 1.

[0039] For certain items, such as medicines and cosmetics, refrigeration at 2℃-8℃ is required. This necessitates further refinement of refrigerator compartments. Therefore, many mid-to-high-end refrigerators are designed with independent storage spaces for medicines and cosmetics. Based on requirements for hygiene, safety, convenience, and consumer experience, this space needs to be relatively sealed. Therefore, designing an operable door for easy access is particularly important. In related technologies, the locking method for refrigerator storage box doors is primarily magnetic adsorption. Strong magnets are expensive, and the structural design and injection molding process for embedding the magnets require high precision. Furthermore, the magnetic force is difficult to control. Specifically, if the magnetic force is too weak, items may easily fall out during refrigerator door opening; if the magnetic force is too strong, accessing items inside the storage box becomes inconvenient, affecting the user experience.

[0040] In this embodiment, the box 1 has at least one storage cavity 11, which means that the box 1 can be divided into multiple independent spaces according to actual needs for storing different items, such as different types of medicines or cosmetics. For example, the number of storage cavities 11 may be one or two. In practical applications, this design with multiple storage cavities 11 can make the classification and storage of items clearer, making it easier for users to find and retrieve the corresponding items.

[0041] One side of the box door 2 is hinged to the box body 1 via a hinge mechanism 4, allowing the box door 2 to rotate around the hinge point like a normal door, thus enabling the box door 2 to open and close. Simultaneously, the box door 2 has a fixing hole 21 and a through hole 22. The fixing hole 21 is used to install a part of the locking mechanism 3, while the through hole 22 allows the locking pin 31 of the locking mechanism 3 to pass through. The box door 2 can seal at least one storage cavity 11, which is crucial for maintaining stable temperature and humidity within the storage cavity 11, especially important for refrigerated cosmetic items.

[0042] In this embodiment, the locking mechanism 3 is a key component of the refrigerator storage box, allowing the other side of the door 2 to connect to the box body 1 via the locking mechanism 3. Specifically, the locking mechanism 3 includes a locking pin 31, a locking rod 32, and a locking bolt 33. The locking pin 31 is mounted on the box body 1, and when the door 2 is closed, the locking pin 31 can pass through the through hole 22 on the door 2. The locking pin 31 has a locking hole 311, which is used to cooperate with the locking bolt 33 to lock the door 2 to the box body 1. The locking rod 32 is mounted on the door 2 through the fixing hole 21 and can rotate around the axis of the fixing hole 21. The locking bolt 33 is mounted on the locking rod 32, and when the locking rod 32 rotates, the locking bolt 33 can extend into the locking hole 311 on the locking pin 31.

[0043] When it is necessary to open the box door 2, rotate the locking rod 32 around the fixing hole 21 (for example, rotate counterclockwise). The locking rod 32 then drives the bolt 33 to rotate until the bolt 33 is completely out of the locking hole 311. Then rotate the box door 2 around the hinge mechanism 4. When the box door 2 rotates, the locking pin 31 will separate from the through hole 22. At this time, the box door 2 is opened. The user can continue to rotate the box door 2 around the hinge mechanism 4 according to actual needs to adjust the opening degree of the box door 2.

[0044] When it is necessary to close the door 2, rotate the door 2 around the hinge mechanism 4 until the locking pin 31 is inserted into the through hole 22. Then, rotate the locking rod 32 around the fixing hole 21 (for example, clockwise). The locking rod 32 then drives the locking bolt 33 to rotate until the locking bolt 33 enters the locking hole 311. At this point, the door 2 is closed, and the door 2 is locked to the body 1. This prevents the door 2 of the storage box from opening automatically during the opening and closing of the refrigerator door, ensuring the safe storage of items. In this way, users can easily access the items in the storage cavity 11.

[0045] Based on the above design, this embodiment incorporates a locking mechanism 3, including a locking pin 31, a locking rod 32, and a locking bolt 33, between the door 2 and the body 1. This locking mechanism 3 makes the use of the refrigerator storage box safer and more convenient. Simply rotating the locking rod 32 allows the door 2 to be opened and locked, making the operation simple and easy to understand. Furthermore, due to its relatively simple structure and low cost, it meets market demands for cost-effectiveness, thereby improving the locking effect between the body 1 and the door 2, and ultimately enhancing the user experience.

[0046] In one possible implementation, please refer again. Figure 4 The locking rod 32 includes a fixed section 322 and a connecting section 321 that are connected to each other. The axis of the fixed section 322 is perpendicular to the connecting section 321. The fixed section 322 is installed on the box door 2 through the fixing hole 21, and the locking bolt 33 is installed on the connecting section 321.

[0047] The locking rod 32 includes a fixed section 322 and a connecting section 321 connected to each other, with the axis of the fixed section 322 perpendicular to the axis of the connecting section 321. This perpendicular design is to allow the locking rod 32 to better drive the bolt 33 to engage with the locking hole 311 on the locking pin 31 during rotation. The fixed section 322 is mounted on the door 2 through the fixed hole 21, allowing the locking rod 32 to rotate around the axis of the fixed hole 21. The bolt 33 is mounted on the connecting section 321; when the locking rod 32 rotates, the connecting section 321 rotates along with the fixed section 322, thereby moving the bolt 33.

[0048] In practical applications, this structural design makes the movement of the locking rod 32 more stable and reliable. The vertical fixed section 322 and the connecting section 321 can ensure that the bolt 33 is accurately aligned with the locking hole 311 on the locking pin 31 during rotation, thereby improving the accuracy and stability of the locking mechanism 3.

[0049] Optionally, the distance from the center of the through hole 22 to the center line of the locking hole 311 is the same as the distance from the center of the fixed post to the center line of the locking bolt 33. In this way, it can be ensured that the center line of the locking hole 311 on the locking post 31 and the center line of the locking bolt 33 always coincide during the rotation of the locking rod 32, thereby improving the locking effect of the locking mechanism 3.

[0050] Optionally, the center line of the through hole 22 coincides with the center line of the bolt 33.

[0051] In one possible implementation, please refer again. Figure 4 The fixing segment 322 includes a first fixing sub-segment 3221 and a second fixing sub-segment 3222 that are connected to each other. The diameter of the first fixing sub-segment 3221 is larger than the diameter of the second fixing sub-segment 3222. The second fixing sub-segment 3222 is connected to the connecting segment 321. The second fixing sub-segment 3222 is clearance-fitted with the fixing hole 21. The first fixing sub-segment 3221 is located outside the fixing hole 21.

[0052] The fixing section 322 includes a first fixing sub-segment 3221 and a second fixing sub-segment 3222 connected to each other. The diameter of the first fixing sub-segment 3221 is larger than that of the second fixing sub-segment 3222. This difference in diameter is designed to achieve better installation and fixing effect. The second fixing sub-segment 3222 is connected to the connecting section 321, and the second fixing sub-segment 3222 is clearance-fitted with the fixing hole 21. This means that the second fixing sub-segment 3222 can rotate relatively freely within the fixing hole 21 while ensuring a certain degree of stability. The first fixing sub-segment 3221 is located outside the fixing hole 21. The function of the first fixing sub-segment 3221 is to prevent the locking rod 32 from coming out of the fixing hole 21, thus serving as a limit.

[0053] In this embodiment, the design of this structure makes the installation of the locking rod 32 on the box door 2 more secure and stable. The clearance fit design not only ensures the rotational flexibility of the locking rod 32, but also prevents the locking rod 32 from loosening or falling off during use through the limiting effect of the first fixed segment 3221, thereby improving the locking effect of the locking mechanism 3 on the box door 2 and the box body 1.

[0054] In one possible implementation, please refer again. Figure 4The first fixed segment 3221 has an elastic opening 32211 at the end away from the connecting segment 321. The elastic opening 32211 extends to a portion of the second fixed segment 3222 and penetrates the first fixed segment 3221 along an axis perpendicular to the first fixed segment 3221.

[0055] The first fixing segment 3221 has an elastic opening 32211 at its end away from the connecting segment 321, and the elastic opening 32211 extends to a portion of the second fixing segment 3222. The elastic opening 32211 penetrates the first fixing segment 3221 along an axis perpendicular to the first fixing segment 3221. This design of the elastic opening 32211 allows the first fixing segment 3221 to undergo a certain degree of elastic deformation during installation, making it easier to pass through the fixing hole 21. After installation, the first fixing segment 3221 returns to its original shape, serving as a limiting function. Specifically, the elastic opening 32211 divides the first fixing segment 3221 into two parts. When the first fixing segment 3221 passes through the fixing hole 21, under the action of compressive force, the two parts of the first fixing segment 3221 move closer to each other. After the first fixing segment 3221 passes through the fixing hole 21, the two parts of the first fixing segment 3221 move away from each other and return to their original shape.

[0056] This design makes it easier to install the fixing section 322 into the fixing hole 21. The flexible opening 32211 greatly improves the convenience of installing and removing the locking rod 32. Users can easily install or remove the locking rod 32 from the box door 2 without using complicated tools, which facilitates product maintenance and replacement.

[0057] Optionally, the fixing section 322 and the connecting section 321 are integrally formed, which can improve the connection strength between the fixing section 322 and the connecting section 321.

[0058] In one possible implementation, please refer again. Figure 4 Along the direction from the first fixed segment 3221 to the second fixed segment 3222, the diameter of the first fixed segment 3221 gradually increases.

[0059] The first fixing segment 3221 is frustum-shaped. When the locking rod 32 is installed on the box door 2, the first fixing segment 3221 is pushed into the fixing hole 21. Since the diameter of the first fixing segment 3221 gradually increases from the first fixing segment 3221 to the second fixing segment 3222, the small end of the first fixing segment 3221 enters the fixing hole 21 first. This makes it easier for the first fixing segment 3221 to pass through the fixing hole 21. At the same time, the diameter of the large end of the first fixing segment 3221 is larger than the diameter of the fixing hole 21, and the large end of the first fixing segment 3221 can better prevent the locking rod 32 from coming out of the fixing hole 21. Thus, the design of the first fixed segment 3221 with a variable diameter further enhances the fixing effect of the locking rod 32 on the door 2, ensuring the normal operation of the locking mechanism 3. Even when the refrigerator door is frequently opened and closed, the locking rod 32 can remain stable and is not prone to loosening or displacement, thereby further improving the locking effect of the locking mechanism 3 on the door 2 and the box body 1.

[0060] In one possible implementation, please refer to Figure 4 and Figure 5 The locking hole 311 includes an arc-shaped hole, and the bolt 33 is bent in the direction of the connecting section 321, and the bolt 33 is arc-shaped.

[0061] The center line of the locking hole 311 coincides with the center line of the bolt 33. The arc-shaped through hole 22 is slightly larger than the bolt 33 to ensure that the bolt 33 passes through smoothly. The head of the bolt 33 is tilted upwards and is positioned slightly higher than the locking hole 311. In this way, the bolt 33 is less likely to fall out of the locking hole 311 during the opening and closing of the refrigerator door, thus preventing the door 2 from opening automatically.

[0062] The locking hole 311 includes an arc-shaped hole, and the bolt 33 bends towards the connecting section 321, forming an arc shape. This arc-shaped design allows the bolt 33 to fit better when inserted into the locking hole 311, improving the stability and reliability of the locking. The arc shape also makes it easier for the bolt 33 to align with the locking hole 311 during rotation, improving the fitting accuracy and locking effect between the bolt 33 and the locking hole 311. Furthermore, it can better withstand external forces in the locked state, preventing the box door 2 from opening accidentally.

[0063] In addition, the arc-shaped design of the locking hole 311 and the bolt 33 effectively reduces wear and extends the service life of the locking mechanism 3. It also improves user convenience, making the process of locking the box door 2 by rotating the locking rod 32 smoother.

[0064] In one possible implementation, please refer to Figure 4 and Figure 5 The locking mechanism 3 also includes a handle 34, which is installed at the end of the connecting section 321 away from the fixed section 322.

[0065] The handle 34 and the connecting section 321 can be integrally formed. The user can rotate the locking rod 32 by holding the handle 34, thereby causing the bolt 33 to extend into or retract from the locking hole 311. The design of the handle 34 makes it easier and more convenient for the user to operate, especially for users with less hand strength, making it easier to open and lock the box door 2.

[0066] In this embodiment, the handle 34 further enhances the ease of use of the refrigerator storage box, allowing users to easily control the rotation of the locking lever 32 to effectively close and open the box door 2. Thus, rotating the handle 34 makes it easier to open or lock the box door 2, ensuring safe and simple operation, thereby further improving the user experience and satisfaction.

[0067] In one possible implementation, please refer again. Figure 2 and Figure 3 The box body 1 has hinge holes 12 that are arranged opposite each other. The hinge mechanism 4 includes a hinge shaft 41, which is installed at the top and bottom of the box door 2 respectively. The hinge shaft 41 is rotatably connected to the hinge hole 12.

[0068] The box body 1 has hinge holes 12 arranged opposite each other. The hinge mechanism 4 includes a hinge shaft 41, which is installed at the top and bottom of the box door 2 and is rotatably connected to the hinge holes 12. This design allows the box door 2 to rotate smoothly around the hinge shaft 41, realizing the functions of opening and closing. The structure of the oppositely arranged hinge holes 12 and hinge shaft 41 ensures the stability of the box door 2 during rotation and prevents shaking or jamming.

[0069] In practical applications, the design of this hinge mechanism 4 makes the opening and closing of the box door 2 smoother and can withstand certain external forces without damage. At the same time, it also facilitates the installation and disassembly of the box door 2, making product production and maintenance easier.

[0070] In one possible implementation, the outer wall of the door 2 has a first buckle 5 and a first slot 6, the first buckle 5 engaging with a second slot on the refrigerator body, and the first slot 6 engaging with a second buckle on the refrigerator body.

[0071] The outer wall of the door 2 has a first buckle 5 and a first slot 6. The first buckle 5 engages with the second slot on the refrigerator body, and the first slot 6 engages with the second buckle on the refrigerator body. Through this engagement of the buckle and slot, the refrigerator storage box can be securely installed on the refrigerator body, preventing shaking or displacement during refrigerator operation.

[0072] In practical applications, this connection method is simple, reliable, and easy to install and remove. Users can easily remove or install the refrigerator storage box from the refrigerator body as needed, facilitating product cleaning and maintenance.

[0073] In summary, when it is necessary to open the refrigerator storage box door 2, the user can rotate the handle 34 to rotate the locking rod 32 around the hole axis of the fixing hole 21. Since the locking bolt 33 is installed on the locking rod 32, the locking bolt 33 will also rotate with the locking rod 32. When the locking bolt 33 rotates to disengage from the locking hole 311 on the locking pin 31, the user can pull the box door 2 outward, separating the locking pin 31 from the through hole 22. At this time, the box door 2 is in the open state. During this process, the box door 2 rotates around the hinge axis 41.

[0074] When it is necessary to close the box door 2, the user pushes the box door 2 towards the box body 1 via the hinge shaft 41, aligning the through hole 22 on the box door 2 with the locking pin 31 on the box body 1, and allowing the locking pin 31 to enter the through hole 22. Then, the user rotates the handle 34 again, causing the locking rod 32 to rotate and the locking bolt 33 to gradually extend into the locking hole 311 on the locking pin 31. When the locking bolt 33 is fully extended into the locking hole 311, the box door 2 and the box body 1 are locked together.

[0075] In practical applications, since the fixing section 322 of the locking rod 32 is installed on the box door 2 through the fixing hole 21, and the second fixing sub-section 3222 of the fixing section 322 is clearance-fitted with the fixing hole 21, while the first fixing sub-section 3221 is located outside the fixing hole 21 and has an elastic opening 32211, this design makes it easier and faster to install the locking rod 32 onto the box door 2. Simultaneously, the elastic opening 32211 allows the first fixing sub-section 3221 to undergo a certain degree of elastic deformation during installation, thereby better securing it to the box door 2.

[0076] In addition, since the locking hole 311 includes an arc-shaped hole, the bolt 33 is arc-shaped and bends towards the connecting section 321. This design allows the bolt 33 to extend into the locking hole 311 more smoothly and to better cooperate with the locking hole 311, thereby improving the reliability of locking.

[0077] In addition, the handle 34 makes it easier for users to rotate the locking lever 32, improving user convenience.

[0078] During the opening and closing of the refrigerator door, since the door 2 is hinged to the body 1 via the hinge mechanism 4, and the door 2 and the body 1 are locked together via the locking mechanism 3, the door 2 will not open automatically, which can effectively protect the safety of the items inside the storage box.

[0079] Based on the above design, the refrigerator storage box provided by the present invention has at least the following beneficial effects:

[0080] The structure is simple and the cost is low. By installing a locking pin 31 on the box body 1, a locking rod 32 and a locking bolt 33 on the box door 2, and setting a hinge mechanism 4, a firm connection and reliable locking between the box door 2 and the box body 1 can be achieved without the need for complex structural design and expensive materials, thus reducing production costs.

[0081] It offers high ease of use and safety. Users can easily open and close the door 2 by rotating the handle 34, making operation simple and convenient. Furthermore, due to the high reliability of the locking mechanism between the door 2 and the body 1, the door 2 will not open automatically during the opening and closing of the refrigerator door, effectively protecting the items inside and greatly enhancing user experience and satisfaction.

[0082] Easy to install. The fixing section 322 of the locking rod 32 is installed on the box door 2 through the fixing hole 21, and the first fixing section 3221 has a flexible opening 32211.
