[0023] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] Embodiment:

[0025] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a chair leg of a seat includes:

[0026] An installation ring 14, the installation ring 14 is of a hollow structure, and the inner wall of the installation ring 14 is wider at the top and narrower at the bottom;

[0027] Five installation feet 13, and the five installation feet 13 are uniformly fixed on the outer periphery of the installation ring 14;

[0028] Five storage openings 11, and the storage openings 11 are opened at one end of the installation foot 13 facing away from the installation ring 14;

[0029] Five groups of clamping rings 20, and the five groups of clamping rings 20 are fixed on the inner walls of the corresponding five installation feet 13;

[0030] Five support legs 16, and the five support legs 16 are rotatably arranged in the corresponding five installation feet 13;

[0031] Ten groups of clamping plates 18, each group of the clamping plates 18 includes two, and every two groups of clamping plates 18 are arranged on both end faces of the corresponding support leg 16; after the support leg 16 is arranged in the installation foot 13, every two groups of clamping plates 18 are arranged on both sides of the corresponding clamping ring 20, and the clamping plate 18 abuts against the clamping ring 20;

[0032] One end of each of the five support legs 16 is inserted into the corresponding five installation feet 13 one by one, so that the clamping plates 18 fixed on the support leg 16 are sleeved on the outer periphery of the corresponding clamping ring 20. With the clamping ring 20 as the rotation center, the support leg 16 is rotated so that the upper end of the support leg 16 abuts against the inner wall of the installation foot 13. With this structure, the support leg 16 and the installation foot 13 can be separated, reducing the occupied space during transportation and storage. And during installation, this installation method does not require screws, accelerating the installation speed. During use, the fixed end of the gas rod on the seat will be placed in the installation ring 14. Under the action of gravity, the upper end of the support leg 16 always abuts against the inner wall of the installation foot 13.

[0033] As Figure 4 shown, each group of clamping rings 20 includes two. The two clamping rings 20 in the same group are symmetrically fixed on the inner walls of both sides of the corresponding installation foot 13. A communication port 21 is opened on each clamping ring 20. A limiting plate 17 is fixed on both end faces of each support leg 16. Each limiting plate 17 is fixed between the two clamping plates 18 in the corresponding same group. When installing the support leg 16, the limiting plate 17 passes through the corresponding limiting frame 22 and then extends into the clamping ring 20. Both ends of the limiting plate 17 are arc-shaped surfaces, and the arc-shaped surfaces at both ends of the limiting plate 17 abut against the inner wall of the clamping ring 20. After the limiting plate 17 extends into the clamping ring 20, the limiting plate 17 can rotate in the clamping ring 20.

[0034] As Figure 2 , Figure 3 and Figure 4 shown, a limiting frame 22 is fixedly arranged on the outer periphery of each clamping ring 20. The thickness of the limiting frame 22 is half of the thickness of the clamping ring 20. Therefore, the clamping plate 18 can rotate around the clamping ring 20 without interfering with the clamping ring 20. The limiting frame 22 communicates with the corresponding communication port 21. One end of the limiting frame 22 close to the clamping ring 20 has an opening smaller than that of the end facing away from the clamping ring 20. With this structure, the limiting plate 17 is not easily separated from the clamping ring 20.

[0035] As Figure 1 shown, a limiting block 12 is fixedly arranged in each mounting leg 13. After the support leg 16 rotates, the upper end of the support leg 16 abuts against the lower end of the limiting block 12. Under the action of the limiting block 12, the clamping ring 20 and the clamping plate 18, when the seat gas strut is placed in the annular ring 14, the support leg 16 maintains a stable state.

[0036] As Figure 1 shown, an installation hole 10 is formed at the bottom end of each support leg 16 facing away from the clamping ring 20. The universal wheel is placed in the installation hole 10. This technology is a conventional technical means, so it will not be described in detail in the specification.

[0037] Working principle:

[0038] Insert one end of the support leg 16 into the mounting leg 13, so that the limiting plate 17 extends into the clamping ring 20 through the limiting frame 22, and the clamping plate 18 is clamped on both sides of the clamping ring 20. With the center of the clamping ring 20 as the rotation center, rotate the support leg 16, install the universal wheel into the installation hole 10, place the end of the support leg 16 with the installation hole 10 close to the ground, and insert the fixed end of the seat gas strut into the installation ring 14.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
