[0018] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] A household refrigerator anti-tipping emergency device, such as Figures 1-4As shown, the refrigerator includes a base 1, a connecting plate 2, a connecting seat 3, a bidirectional screw 31, a rotating handle 32, a clamping plate 33, a sliding plate 34, and an elastic element 36. The base 1 has an internal placement cavity 11, which supports the overall weight of the refrigerator. The refrigerator is placed inside the placement cavity 11. The rear end of the base 1 is connected to the connecting plate 2. Positioning holes 21 are sequentially spaced from top to bottom on both sides of the connecting plate 2. The front end of the connecting plate 2 is slidably connected to the connecting seat 3. The bidirectional screw 31 is rotatably connected to the connecting seat 3. The right end of the bidirectional screw 31 is connected to the rotating handle 32. Handle 32 is used to manually operate the rotation of the bidirectional screw 31. Both sides of the bidirectional screw 31 are threaded with clamping plates 33. The bidirectional screw 31 is used to convert rotational motion into linear motion, driving the clamping plates 33 on both sides to move synchronously. The ends of the two clamping plates 33 that are close to each other are slidably connected with sliding plates 34. Both clamping plates 33 have square holes 331. An elastic element 36 is connected inside the square hole 331. The other end of the elastic element 36 is connected to the sliding plate 34. The sliding plate 34 is sleeved on the clamping plate 33. The contact area between the sliding plate 34 and the clamping plate 33 gradually decreases from front to back.

[0020] like Figure 1 and Figure 2 As shown, it also includes guide rails 15, pressing plates 16, flexible pads 161, and springs 17. The inner bottom end of the base 1 is symmetrically provided with grooves 14, and each groove 14 is provided with a guide rail 15. Each guide rail 15 is connected to a pressing plate 16. The guide rails 15 are used to guide the lateral sliding of the pressing plates 16 to ensure that their movement is smooth and accurate. The ends of the two pressing plates 16 that are close to each other are connected with flexible pads 161. The flexible pads 161 are used to increase the friction between the pressing plates 16 and the refrigerator, and at the same time avoid scratching the surface of the refrigerator. The ends of the two pressing plates 16 that are far apart from each other are provided with springs 17 from front to back. The other end of the springs 17 is connected to the inner wall of the adjacent base 1.

[0021] like Figures 1-3 As shown, it also includes wheels 12, sponge pads 13 and rubber plates 35. Wheels 12 are installed on the four corners of the bottom of the base 1. All wheels 12 are omnidirectional wheels, which facilitate the overall movement of the equipment. Sponge pads 13 are connected to the inner wall of the base 1. The sponge pads 13 are used to buffer the collision between the refrigerator and the inner wall of the base 1 and protect the refrigerator shell from damage. Rubber plates 35 are provided at the ends of the two sliding plates 34 that are close to each other. The rubber plates 35 are used to enhance the friction between the sliding plates 34 and the outer wall of the refrigerator.

[0022] Move the device to the location where the refrigerator is placed, ensuring the rear end of the connecting plate 2 is flush against the wall. Use expansion screws to pass through the positioning holes 21 and secure the device to the wall. Before placing the refrigerator into the base 1, use a tool to push the two clamping plates 16 apart. During this process, the springs 17 between the clamping plates 16 and the inner wall of the base 1 change from their initial state to a compressed state. When the distance between the clamping plates 16 is sufficient to accommodate the refrigerator, lift the refrigerator and place it into the placement cavity 11 inside the base 1. Release the two clamping plates 16. Under the action of the spring 17 (at this time, the spring 17 begins to return to its original position), the two clamping plates 16 will move closer together until the flexible pads 161 on the clamping plates 16 touch the inner wall of the refrigerator. At this time, all the springs 17 are in a compressed state. Under the action of the spring 17, the clamping plates 16 will touch the lower part of the refrigerator, thus fixing the lower part of the refrigerator. Adjust the connecting seat 3 on the connecting plate 2 by pulling it upward. The position of the clamping plates 33 on both sides is such that they come to the upper part of the refrigerator (the connecting seat 3 slides upward along the connecting plate 2). Then, the rotating handle 32 is rotated, which drives the double-direction screw 31 to rotate. Under the action of the double-direction screw 31, the two clamping plates 33 move closer to each other along their axial direction, thereby driving the sliding plate 34 to move synchronously. When the rubber plate 35 at the front end of the sliding plate 34 is in close contact with the outer wall of the refrigerator, the rotating handle 32 is stopped, thus completing the fixation of the upper part of the refrigerator. If the two rubber plates 35 are not tightly clamped to the outer wall of the refrigerator, but only in contact with the outer wall of the refrigerator, the upper part of the refrigerator can still sway forward. When the upper part of the refrigerator has a tendency to tilt forward, the outer wall of the refrigerator will rub against the rubber plate 35, causing the sliding plate 34 to slide forward along the clamping plate 33. During the forward sliding of the two sliding plates 34, the distance between the two sliding plates 34 gradually decreases, which makes the rubber plate 35 on the two sliding plates 34 tightly clamp the refrigerator to prevent the refrigerator from tilting further. During this process, the elastic element 36 will gradually change from the initial state to the extended state.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
