[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household product that keeps food or other items in a constant low temperature state. Due to its large size, a refrigerator needs a bottom foot structure with a height adjustment function to ensure stable support.

[0003] However, in the prior art, for the bottom foot structure that supports the refrigerator, the operation of adjusting the height of the refrigerator is achieved by rotating the bottom feet that support the refrigerator. However, the bottom feet are all at the bottom of the refrigerator, which greatly increases the possibility of squeezing the hand when adjusting the height of the bottom feet and causing harm to the hand. Therefore, a new type of adjusting foot seat assembly for a refrigerator needs to be proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that for the bottom foot structure that supports the refrigerator, the operation of adjusting the height of the refrigerator is achieved by rotating the bottom feet that support the refrigerator. However, the bottom feet are all at the bottom of the refrigerator, which greatly increases the possibility of squeezing the hand when adjusting the height of the bottom feet and causing harm to the hand. By setting a foot seat assembly whose side can adjust the bottom feet, the problem raised in the background technique is solved.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an adjusting foot seat assembly for a refrigerator, including: a component body, two driving chambers are opened inside the component body, the bottom of each of the two driving chambers is movably inserted with a first bevel gear, the bottom ends of the two first bevel gears are fixedly installed with threaded rods, and the outer surfaces of the two threaded rods are movably inserted into the inner surface of the component body. The outer surfaces of the two threaded rods are rotatably sleeved with bottom foot seats. One side of the inner wall of each of the two driving chambers is movably inserted with a second bevel gear, and the outer surfaces of the two second bevel gears are respectively meshed with the outer surfaces of the two first bevel gears. One end of the outer wall of each of the two second bevel gears is fixedly installed with a rotating shaft, and the outer surfaces of the two rotating shafts respectively penetrate through both sides of the outer wall of the component body, and the outer surfaces of the two rotating shafts are rotatably inserted into the inner surface of the component body.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-3 shown, the present utility model provides an adjustable footrest assembly for a refrigerator, including: a component body 1, two driving chambers 2 are opened inside the component body 1, the bottoms of the two driving chambers 2 are both movably inserted with first bevel gears 3, the bottoms of the two first bevel gears 3 are both fixedly installed with threaded rods 4, and the outer surfaces of the two threaded rods 4 are both movably inserted into the inner surface of the component body 1, the outer surfaces of the two threaded rods 4 are both rotatably sleeved with bottom footrests 5, one side of the inner walls of the two driving chambers 2 are both movably inserted with second bevel gears 6, and the outer surfaces of the two second bevel gears 6 are respectively meshed with the outer surfaces of the two first bevel gears 3, one ends of the outer walls of the two second bevel gears 6 are both fixedly installed with rotating shafts 7, and the outer surfaces of the two rotating shafts 7 respectively penetrate through both sides of the outer wall of the component body 1, and the outer surfaces of the two rotating shafts 7 are both rotatably inserted into the inner surface of the component body 1.

[0023] The effect achieved by the entire Embodiment 1 is that after installing the component body 1 at the bottom of the refrigerator and placing it on the ground, if it is found that one corner of the refrigerator is in a floating state, it can be moved to that side of the refrigerator, and the rotating shaft 7 on that side can be rotated. By using the principle of gear transmission, the threaded rod 4 is driven to rotate, thereby adjusting the height of the footrest 5 so that the bottom of the footrest 5 can contact the ground to achieve the supporting effect without reaching under the refrigerator with hands, thus improving the safety when adjusting the balance of the refrigerator.

[0024] Embodiment 2 is as Figures 1-4 shown. A fixed plate 8 is welded to the inner wall of the component body 1, and two limit posts 9 are welded to the bottom of the component body 1. The outer walls of the two limit posts 9 are both movably sleeved with limit frames 10, and the outer walls of the two limit frames 10 are respectively fixedly connected to the outer walls of the two footrests 5. Rubber pads 11 are fixedly installed at the bottoms of the two footrests 5. Knobs 12 are fixedly sleeved on the outer walls of the two rotating shafts 7, and a plurality of grooves are formed on the outer walls of the two knobs 12. Identification lines 13 are provided at one ends of the outer walls of the two knobs 12. A plurality of legs 14 are fixedly installed on the outer wall of the component body 1 by means of threading.

[0025] The effect achieved by the entire Embodiment 2 is that by providing the legs 14, it is convenient to set up an anti - tipping structure for the refrigerator. When the footrest 5 breaks or the height of the footrest 5 is too high without sufficient support, the legs 14 are used to support the refrigerator to prevent the bottom of the refrigerator from hitting the ground and damaging the appearance. At the same time, the knobs 12 are also provided to facilitate the rotation of the rotating shaft 7. Whenever the rotating shaft 7 is needed.

[0026] The working principle of the entire device is as follows: After installing the component body 1 at the front bottom of the refrigerator, rotate the knob 12 so that the bottoms of the two footrests 5 are on the same plane as the fixed support device at the rear bottom of the refrigerator, and then the refrigerator can be placed on the ground. If the ground where it is placed is not flat, then one corner of the bottom of the refrigerator will be in a floating state. At this time, the knob 12 on that side can be held and rotated. During the rotation, the first bevel gear 3 will drive the second bevel gear 6 to rotate, thereby causing the threaded rod 4 to rotate. At this time, the footrest 5 will move up and down through the threaded structure until the rubber pad 11 at the bottom of the footrest 5 contacts the ground and is squeezed by the footrest 5. In this way, it can be ensured that the refrigerator can be stably supported on the ground. If the two footrests 5 are not adjusted after installation, there will be no support at the front side of the refrigerator and it will tip over. When the refrigerator tips over to a certain angle, it will be supported by multiple supports to avoid damage to the appearance of the refrigerator shell due to impact.

[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
