The buffer pad 10 can play a role in buffering and shock absorption, reducing the collision and wear between the positioning screw 9 and surrounding parts; at the same time, it can also increase the friction, making the positioning screw 9 more securely installed.

[0033] As a preferred embodiment, a sealing gasket 12 is detachably provided at the bottom of the main pipe 1. The sealing gasket 12 is made of a material with good flexibility and sealing performance, and can fit tightly against the contact surface. When performing the installation operation, simply place the sealing gasket 12 stably at the corresponding position at the bottom of the main pipe 1, and the bottom of the sealing gasket 12 will fit tightly against the upper surface of the third screw hole 11. The sealing gasket 12 can effectively fill the small gaps between the bottom of the main pipe 1 and the adjacent components, preventing dust, moisture and other impurities from entering the interior of the main pipe 1.

[0034] In a preferred embodiment, a plurality of support plates 14 are evenly installed inside the base 13. The support plates 14 not only provide structural support but also enhance the stability of the base 13 itself. A counterweight 15 is fixedly installed between two adjacent support plates 14. The addition of the counterweight 15 increases the weight of the entire device, lowers the center of gravity, and makes the main pipe 1 run more smoothly, reducing the risk of shaking and tipping.

[0035] In a preferred embodiment, a positioning rod 19 is fixedly installed on the upper side of the buffer plate 18. The size of the positioning rod 19 is adapted to the through hole 17 opened at the bottom of the base 13. During the installation of the buffer plate 18, the buffer plate 18 is aligned with the appropriate position at the bottom of the base 13, and the positioning rod 19 can be inserted into the through hole 17. This not only provides a positioning function for the installation of the buffer plate 18, ensuring that its installation position is accurate, but also limits the displacement of the buffer plate 18 to a certain extent, so that it can stably perform the buffering and shock absorption function when subjected to external forces.

[0036] As a preferred embodiment, the bottom of the base 13 is provided with a limiting groove 20, the shape and size of the limiting groove 20 are designed to meet the subsequent positioning requirements, the upper side of the buffer piece 18 is fixedly provided with a limiting ring 21, the position of the limiting ring 21 corresponds to the limiting groove 20 at the bottom of the base 13, when the base 13 and the buffer piece 18 are overlapped during the installation operation, the limiting ring 21 can be inserted into the inside of the limiting groove 20, so that the buffer piece 18 is effectively prevented from being deviated in the horizontal direction, and the connection between the buffer piece 18 and the base 13 is more stable and reliable.

[0037] In the embodiment, the main pipe 1 and the bearing plate 2 are devices known to those skilled in the art and can be directly purchased on the market, and can be customized or selected according to actual needs, and here, we only use them and do not improve their structure and function, and will not be described in detail here.

[0038] The working process of the utility model is as follows: first, before assembling the sofa foot, the sealing gasket 12 is stably placed at the corresponding position of the bottom of the main pipe 1, so that the bottom is tightly attached to the upper surface of the third screw hole 11, to prevent dust and other impurities from entering the inside of the main pipe 1, then the bearing plate 2 is stably placed at the appropriate position of the top of the main pipe 1, at this time, the first screw hole 4 and the second screw hole 6 are aligned, then the positioning bolt 7 with the matching thread is screwed into the second screw hole 6 and continues to extend into the first screw hole 4, the head of the positioning bolt 7 is located in the groove 5, the fixed connection of the main pipe 1 and the bearing plate 2 is completed, then the positioning screw rod 9 is installed into the positioning hole 8 of the bearing plate 2, and the buffer gasket 10 is sleeved outside the positioning screw rod 9, to ensure that the inside of the buffer gasket 10 is in close contact with the outside of the positioning screw rod 9, and to provide buffer protection for the sofa body, then the outer screw rod 16 at the upper side of the base 13 is aligned with the third screw hole 11 at the bottom of the main pipe 1, the outer screw rod 16 is screwed into the third screw hole 11, to realize the connection of the main pipe 1 and the base 13, and the support piece 14 and the counterweight 15 in the base 13 can increase the overall weight of the sofa foot, lower the gravity center and improve the stability.

[0039] The buffer piece 18 is aligned with the appropriate position at the bottom of the base 13, the positioning rod 19 is inserted into the through hole 17, and the limiting ring 21 is inserted into the limiting groove 20, to complete the installation of the buffer piece 18 and the base 13. The buffer piece 18 can increase the friction with the ground and play a buffering role when the sofa moves or is stressed, to reduce noise and impact on the sofa foot.

[0040] When people sit or stand up on the sofa, the sofa body exerts pressure on the bearing plate 2, the bearing plate 2 transmits the pressure to the main pipe, the main pipe transmits the pressure to the buffer sheet 18 through the base 13, the buffer sheet 18 and the buffer gasket 10 can absorb and disperse the pressure, reduce the impact on the sofa foot and the sofa body, at the same time, the counterweight 15 increases the stability of the sofa foot, so that the sofa is not easy to shake, when moving the sofa, the buffer sheet 18 can also reduce the noise generated with the ground. The working principle of the metal sofa foot with the above-mentioned buffering structure is described.
