Problems solved by technology

In order to meet the use requirements of some special groups of people, such as people who are taller and heavier, the footrest is generally designed to be of a larger size, which includes an inner connection sleeve, an outer footrest ring, and a connecting ring connecting the inner connection sleeve and the outer footrest ring. Reinforcement ribs are generally connected by bolted joints or welding. This connection method, when used by larger and heavier people, has the problem that the connection is easy to loosen or the weld is easy to break, and the stability is poor. Use less effective
In addition, this footrest is fixed and cannot adjust its position adaptively according to the height of the user.

Embodiment 1

[0021] Embodiment 1: as figure 1 As shown, a high-strength swivel chair footrest includes an inner connecting sleeve 2 connected to the swivel chair rotating shaft 1, an outer footrest ring 3 coaxially arranged with the inner connecting sleeve 2, and connecting the inner connecting sleeve 2 and The plurality of reinforcing ribs 4 of the outer footrest 3, the inner connecting sleeve 2, the outer footrest 3 and the plurality of reinforcing ribs 4 are integrally formed. Compared with the prior art, in this application, the inner connecting sleeve 2, the outer footrest ring 3 and the plurality of reinforcing ribs 4 are integrally formed, and the overall strength is high, which is effectively suitable for larger and heavier people, and has a good use effect.

[0022] preferred, such as figure 2 As shown, the inner connecting sleeve 2 is provided with a locking screw 21 , and the inner connecting sleeve 2 is provided with a locking piece 23 which can be pushed by the locking screw...

Embodiment 2

[0025] Embodiment 2: different from embodiment 1, such as image 3 Preferably, the inner connection sleeve 2 includes a tapered sleeve 25 , the tapered mouth of the tapered sleeve 25 is small at the top and large at the bottom, and the rotating shaft 1 of the swivel chair includes a tapered column 11 matched with the tapered sleeve 25 . This setting, the inner connection sleeve 2 and the swivel chair rotating shaft 1 ensure the stability of the connection between the inner connection sleeve 2 and the swivel chair rotating shaft 1 through the mutually matched tapered sleeve 25 and the tapered column 11.

[0026]Because the center of gravity of people of different heights is different, the position of the best footrest is also different, that is to say, the position of the inner connection sleeve 2 in the vertical direction is also different, so people of different heights need to adjust the height of the inner connection sleeve 2 Preferably, the tapered sleeve 25 includes a sle...

Abstract

The invention relates to a high-strength leg supporting stool for a revolving chair. The leg supporting stool comprises an inner connecting sleeve, an outer leg supporting ring and a plurality of reinforcing ribs, wherein the inner connecting sleeve is connected with a rotating shaft of the revolving chair, the outer leg supporting ring the inner connecting sleeve and the inner connecting sleeve are coaxially arranged, the outer leg supporting ring and the reinforcing rings are integrally formed. The high-strength leg supporting stool is suitable for relatively high and heavy people and has the advantages of good integral strength and use effect and the like.

Description

technical field [0001] The invention relates to a high-strength swivel chair footrest. Background technique [0002] The swivel chair is a chair commonly used in bars, and its rotating shaft is usually provided with a footrest to meet the needs of use. In order to meet the use requirements of some special groups of people, such as people who are taller and heavier, the footrest is generally designed to be of a larger size, which includes an inner connection sleeve, an outer footrest ring, and a connecting ring connecting the inner connection sleeve and the outer footrest ring. Reinforcement ribs are generally connected by bolted joints or welding. This connection method, when used by larger and heavier people, has the problem that the connection is easy to loosen or the weld is easy to break, and the stability is poor. Use The effect is poor. In addition, this footrest is fixed, and cannot adjust its position adaptively according to the height of the user. Contents of th...
