In the third aspect, the manufacturing cost of the plastic piece is lower than that of the metal piece, so that the manufacturing cost of the furniture supporting leg 1 can be reduced by implementing the embodiment.

In the fourth aspect, the adjusting leg 132 and the mounting base 131 made of plastic are lighter, which is advantageous for transportation of the furniture supporting leg 1.

In a specific embodiment, the mounting structure 12 includes a screw 121, and the tail of the screw 121 protrudes from the housing 11, so that the furniture supporting leg 1 can be connected with the furniture by screwing the tail of the screw 121 into a threaded hole in the bottom of the furniture.

In an embodiment, the interior of the housing 11 is a hollow structure, the bottom of the housing 11 has a through hole 111 communicating with the inner space thereof, and the mounting base 131 penetrates into the through hole 111 and is in interference fit with the inner wall of the housing 11.

The advantage of this embodiment is that no glue or other structure is required to connect the housing 11 and the mounting base 131, so the structure is simpler and the assembly cost is lower.

In an embodiment, the outer side wall of the mounting base 131 is provided with a protruding rib 1312, and the protruding rib 1312 is in interference fit with the inner side wall of the housing 11.

Specifically, if the overall contour of the outer sidewall of the mounting base 131 is larger than that of the inner sidewall of the housing 11, it is very difficult to insert the mounting base 131 into the through hole 111, so that it is very difficult to achieve an interference fit between the mounting base 131 and the inner wall of the housing 11. In order to make the mounting base 131 easier to assemble to the housing 11, the present embodiment is provided with ribs 1312 on the outer side wall of the mounting base 131, and interference fit between the mounting base 131 and the inner side wall of the housing 11 is achieved by means of the ribs 1312.

In a specific embodiment, the ribs 1312 are provided with a plurality of ribs 1312 spaced apart in the gravity direction, so that the reliability of the connection of the housing 11 with the mounting base 131 can be improved.
