[0033] Example 1

[0034] Reference Figs. 1-3 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0035] Refrigerator body 100;

[0036] A limiting unit 200 is disposed on the refrigerator body 100 and is used to limit the opening and closing of the refrigerator body 100 door panel. A damping component 300 is disposed on the limiting unit 200 and is used to slow down the opening and closing of the limiting unit 200.

[0037] A connecting component 400 is disposed on the limiting unit 200 and is used to connect the limiting unit 200 to the refrigerator body 100.

[0038] When in use, the limiting unit 200 can effectively restrict the opening and closing of the refrigerator door, ensuring a stable storage environment for food inside and that the cooling effect is not affected. At the same time, it prevents children from accidentally opening the refrigerator door while playing and causing danger. The damping component 300 has a buffering effect on the opening and closing of the limiting unit 200, making the opening and closing process smoother and gentler, and reducing the noise interference generated when restricting the opening and closing. The connecting component 400 ensures that the limiting unit 200 is firmly installed between itself and the refrigerator.

[0039] Example 2

[0040] Reference Figs. 1-3 This is the second embodiment of the present invention, which differs from the previous embodiment in that...

[0041] The limiting unit 200 includes a left side plate 201 and a right side plate 202. Both the left side plate 201 and the right side plate 202 are attached to the refrigerator body 100. The left side plate 201 has a connection port 203, and the right side plate 202 has a movable port 204. Two crossbars 205 are fixedly connected to one inner wall of the movable port 204. The arms of the two crossbars 205 are slidably connected to sliders 206. A connecting plate 207 is fixedly connected to one side surface of the two sliders 206. The connecting plate 207 is inserted into the connection port 203. Springs 208 are sleeved on the arms of the two crossbars 205. The two ends of the two springs 208 are fixedly connected to the movable port 204 and the sliders 206, respectively. A handle 209 is fixedly connected to the sides of the two sliders 206 that are far apart from each other.

[0042] The connection between the connector 203 and the connector plate 207 allows users to easily open and close the refrigerator door with simple plugging and unplugging actions, effectively preventing accidental opening of the refrigerator door and ensuring a stable internal food storage environment. When the handle 209 is pulled, the slider 206 slides on the crossbar 205, compressing the spring 208 and causing the connector plate 207 to disengage from the connector 203. After the refrigerator door is closed, releasing the handle 209 causes the spring 208 to automatically reset due to its elastic potential energy, allowing the connector plate 207 to re-insert into the connector 203 and complete the locking process. This eliminates the need for manual alignment and reduces the difficulty of use.

[0043] Specifically, the damping assembly 300 includes a damping block 301, which is fixedly connected to one side surface of the right side plate 202, and the damping block 301 is in contact with the side of the connecting plate 207 that is close to each other.

[0044] When the refrigerator door is opened and closed, the damping block 301 acts on the connecting plate 207 to slow down the movement speed of the connecting plate 207, thereby reducing the noise generated by the opening and closing of the refrigerator door, avoiding disturbing the environment, and preventing items inside the refrigerator from shaking or the door panel from colliding due to excessively fast opening and closing.

[0045] Specifically, the connecting component 400 includes two mounting plates 401, which are fixedly connected to the corresponding left side plate 201 and right side plate 202 respectively, and both mounting plates 401 are fixedly connected to the refrigerator body 100.

[0046] During use, the left side plate 201 and the right side plate 202 are fixed to the refrigerator body 100 by the mounting plate 401, which strengthens the overall structural stability of the limiting unit 200, prevents displacement or loosening due to vibration during use, and ensures the fitting accuracy of the door lock components.

[0047] Example 3

[0048] Reference Fig. 2 This is the third embodiment of the present invention, which differs from the previous embodiment in that...

[0049] A storage board 2011 is fixedly connected to one side surface of the left side panel 201, and sticky notes and pens are placed inside the storage board 2011.

[0050] The 2011 storage board features built-in sticky notes and a pen, allowing users to easily record the storage status of food items in the refrigerator, expiration dates, or shopping lists, avoiding forgetting items and reducing the hassle of frequently opening and closing the refrigerator door to find them, thus improving the convenience of life.

[0051] Specifically, a fluorescent indicator panel 2021 is fixedly connected to the side surface of the right side panel 202 away from the refrigerator body 100.

[0052] The 2021 fluorescent indicator panel utilizes fluorescent properties to enable the door lock mechanism to automatically illuminate in low light conditions at night, clearly marking the location of the refrigerator door and preventing users from accidentally bumping into the refrigerator at night or in dim environments.

[0053] Specifically, both sides of the right side plate 202 are fixedly connected to a baffle plate 2022, and the handle 209 is slidably connected within the two baffle plates 2022.

[0054] It can limit and protect the handle 209, guide the sliding trajectory of the handle 209, avoid deviation and jamming, ensure smooth opening and closing operation, and at the same time cover the internal slider 206, spring 208 and other components to prevent dust accumulation and external impact, thus extending their service life.

[0055] Specifically, a soft sleeve 2091 is fixedly connected to the handle 209, and the soft sleeve 2091 is provided with anti-slip texture.

[0056] When in use, the Soft Cover 2091 is made of flexible material that fits the palm of the hand when held, reducing the harsh touch, while the anti-slip texture increases friction, so that even if the user's hands are wet, the force can be applied steadily, and slippage can be avoided during opening and closing.

[0057] During use, the user holds the non-slip textured soft sleeve 2091 on the handle 209 and pulls it to one side. The handle 209 causes the slider 206 to slide on the crossbar 205. Simultaneously, the slider 206 compresses the spring 208, causing the connecting plate 207 to be pulled out from the connection port 203 of the left side plate 201, releasing the restriction on the refrigerator door. At this point, the refrigerator door can be opened. During the movement of the connecting plate 207 by the handle 209, the damping block 301 engages with the connecting plate 207, damping its movement and slowing down the opening and closing speed, making the door opening and closing action smoother. Conversely, the user moves the handle 209 while the connecting plate 207 is in contact with the handle, providing damping and slowing down the opening and closing speed. When closing the refrigerator door, releasing the handle 209 causes the slider 206 to slide the connecting plate 207 in the opposite direction under the elastic force of the spring 208, allowing it to re-insert into the connecting port 203 and close the door more slowly, locking it in place. The side panels 2022 act as limiters and protectors, ensuring the handle 209 slides stably. In addition, the storage plate 2011 on the left side panel 201 allows users to place sticky notes and pens to record the storage status of items inside the refrigerator or leave messages. The fluorescent indicator plate 2021 on the right side panel 202 can remind users of the refrigerator door's location at night, making it convenient for users.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
