[0002] At present, various office supplies, furniture, electrical appliances and other items can be seen everywhere in people's lives and work. We often have such troubles. The legs of some office supplies or furniture are too short, which makes it difficult to move or move them, and it is not convenient to clean the dust at the bottom or for a sweeping robot to enter; some furniture or electrical appliances such as washing machines have a small distance from the ground, which makes it easy to touch water and accelerate the rust and corrosion of the washing machine.

[0003] In order to solve the above problems, currently, people usually install rubber pads at the bottom of various office appliances, furniture or electrical appliances to increase their height. However, during long-term use, the rubber pads will gradually become hard and brittle, and cracks and bubbles will appear on the surface, thereby shortening the service life. At the same time, the height increase of the rubber pads is limited, and they are easily flattened during long-term pressure. In addition, the appearance of the rubber pads is poor.

[0007] When in use, it is necessary to set a plurality of furniture supporting feet at the bottom of various office appliances, furniture or electrical appliances. The upper support, middle support and lower support of the furniture supporting feet can be made of hard materials such as plastic or metal. In addition, the one-piece molded structure makes it have higher hardness. At the same time, the upper support and the lower support are both in the shape of an inverted frustum. Because the furniture is rigidly connected to the upper part of the supporting foot, the lateral force is smaller at the bottom and larger at the top. By setting the upper support and the lower support to an inverted frustum, it is possible to save materials and increase visual beauty while ensuring the supporting performance of the supporting foot. The middle support includes a main columnar supporting part and a plurality of V-shaped auxiliary supporting parts. The main columnar supporting part can play a major supporting role, while the plurality of V-shaped auxiliary supporting parts can increase the extension space of the supporting foot during the compression process, thereby increasing the support capacity. The compression stroke is increased, thereby greatly improving the bearing capacity, deformation resistance and supporting area of ​​the support foot. In addition, the upper support, middle support and lower support are respectively arranged to abut against each other up and down, so that the support foot has higher structural strength and better supporting performance, thereby making the support foot more durable. In addition, the detachable upper support, middle support and lower support are convenient for the replacement of their respective accessories, and the upper support, middle support and lower support can be electroplated with different colors respectively. Electroplating can not only increase the aesthetics and meet the personalized needs of users, but also enhance the corrosion resistance. In addition, the structure of several V-shaped secondary support parts arranged circumferentially along the columnar main support part makes the support foot more unique, thereby improving the supporting reliability of the support foot while meeting the personalized needs of users for the support foot.

[0008] In addition, the upper support, middle support and lower support of the furniture support leg themselves have a certain height, which can effectively raise the height of various office tools, furniture, electrical appliances and other items, making it easier to clean the dust at the bottom or for a sweeping robot to enter and exit.

By arranging the side wall of the annular step groove 1 in the weight-reducing groove 1 and abutting against the side wall of the weight-reducing groove 1, the upper support and the middle support can form a mutual limit in the radial direction after being connected, avoiding radial relative displacement and affecting the structural strength of the support leg itself, and also making the upper support and the middle support better abut up and down, so that the structure of the support leg is more stable and reliable. In addition, by arranging the weight-reducing groove 1 with the notch facing downward on the upper support, the manufacturing cost of the upper support can be reduced on the basis of ensuring the structural strength of the upper support.

[0012] In the above-mentioned furniture support leg, the edge of the lower connection part has a second edge protruding downward, the lower support has a second weight-reducing groove with a notch facing upward, the notch edge of the second weight-reducing groove has a second annular step groove, and the side wall of the second annular step groove is located inside the second edge and abuts against the side wall of the second edge. By arranging the side wall of the second annular step groove inside the second edge and abutting against the side wall of the second edge, the middle support and the lower support can form a radial mutual limit after the connection, avoiding radial relative displacement and affecting the structural strength of the support leg itself, and also making the middle support and the lower support better abut up and down, so that the structure of the support leg is more stable and reliable. In addition, by arranging the second weight-reducing groove with a notch facing upward on the lower support, the manufacturing cost of the lower support can be reduced on the basis of ensuring the structural strength of the lower support.

[0013] In the above-mentioned furniture support leg, the side wall of the upper support has a plurality of linear knurlings arranged along the circumference thereof, and the upper and lower ends of the linear knurlings extend to the upper and lower ends of the upper support respectively.
