[0029] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0030] like Figures 1 to 5As shown, a high-stability chair 10 includes a bracket 100 and a sliding assembly 200. A seat cushion 300 is provided on the top of the bracket 100, and a plurality of spaced-apart supporting legs 400 are provided on the bottom of the bracket 100. The sliding assembly 200 includes a rotary rod 210, a slide 220 and a plurality of sliding wheels 230. The slide 220 is slidably arranged on the bracket 100 along the vertical direction. The rotary rod 210 is rotatably arranged on the bracket 100, and the rotary rod 210 is screwed to the slide 220. Each sliding wheel 230 is slidably arranged at the bottom of the slide 220. The rotary rod 210 is used to drive the slide 220 to perform lifting movements so that the sliding wheels 230 can perform lifting movements relative to the supporting legs 400. When each sliding wheel 230 slides horizontally relative to the slide 220, each sliding wheel 230 is aligned with or staggered with each supporting leg 400.

[0031] It should be noted that the seat cushion 300 is mounted on the top of the bracket 100 by screws, and a plurality of legs 400 are provided at the bottom of the bracket 100, wherein any two adjacent legs 400 are equidistantly distributed. In one embodiment, four legs 400 are provided, and the legs 400 are used to contact the ground. Furthermore, the slide 220 can be raised and lowered relative to the bracket 100. The rotary rod 210 is rotatably connected to the bracket 100, and the rotary rod 210 is screwed to the slide 220. In this way, the user can adjust the slide 220 to be raised and lowered by rotating the rotary rod 210. Each sliding wheel 230 is slidably installed at the bottom of the slide 220 in a transverse direction. By applying a transverse thrust to the sliding wheel 230, the sliding wheel 230 can slide transversely to the bottom of the leg 400, or laterally away from the bottom of the leg 400. In this way, by rotating the rotary rod 210, the slide cylinder 220 drives each sliding wheel 230 to descend. When the sliding wheel 230 is lower than the support leg 400, the sliding wheel 230 is slid to the bottom of the support leg 400, and then the rotary rod 210 is rotated in the opposite direction to make the sliding wheel 230 rise until the sliding wheel 230 is inserted into the support leg 400. At this time, the sliding wheel 230 serves as the support part of the chair, so the chair can be moved anywhere. On the contrary, rotating the rotary rod 210 drives the sliding wheel 230 to descend, and the sliding wheel 230 withdraws from the support leg 400. Then, a lateral thrust is applied to the sliding wheel 230 to make the sliding wheel 230 move away from the support leg 400. Then, the rotary rod 210 is rotated to drive the sliding wheel 230 to rise. When the lowest point of the sliding wheel 230 is higher than the bottom side of the support leg 400, the chair uses the support leg 400 as the support part. Since the support leg 400 and the bracket 100 are fixedly installed, they have sufficient structural stability and effectively have the advantages of both mobility and reliability and stability.

[0032] like Figure 2 and Figure 5As shown, in one embodiment, the sliding wheel 230 includes a universal wheel 231 and a plug post 232 . The plug post 232 is disposed on the universal wheel 231 . A socket 410 is provided in the support leg 400 . The plug post 232 is adapted to be inserted into the socket 410 .

[0033] It should be noted that the universal wheel 231 is a prior art and will not be described in detail here. The plug post 232 is located on the universal wheel 231. In this way, by fitting the plug post 232 into the socket 410 of the support leg 400, the chair can be slidable through the universal wheel 231.

[0034] like Figure 1 As shown, in one embodiment, a rubber sleeve 510 is provided on the support leg 400 , and the end surface of the support leg 400 is located in the rubber sleeve 510 .

[0035] It should be noted that when the support leg 400 is in contact with the ground, the chair is fixed and immobile. To prevent the support leg 400 from directly contacting the ground and causing wear on the socket 410 of the support leg 400, a rubber sleeve 510 is mounted on the support leg 400. The bottom surface of the rubber sleeve 510 extends beyond the end surface of the support leg 400. This allows the rubber sleeve 510 to directly contact the ground, thus preventing wear on the support leg 400.

[0036] like Figure 6 As shown, in one embodiment, a limiting piece 520 is provided on the outer side wall of the support leg 400 , and the rubber sleeve 510 abuts against the limiting piece 520 .

[0037] It should be noted that the limiting plate 520 is welded and installed on the outer wall of the support leg 400, wherein the distance between the limiting plate 520 and the end face of the support leg 400 is less than the height of the rubber sleeve 510. Therefore, when the rubber sleeve 510 is put on the support leg 400, ensure that the rubber sleeve 510 exceeds the end face of the support leg 400.

[0038] like Figure 5 and Figure 6 As shown, in one embodiment, the sliding wheel 230 also includes a support plate 233 and a top block 234, the universal wheel 231 is arranged on the lower side of the support plate 233, the top block 234 is arranged on the upper side of the support plate 233, the plug post 232 is located on the top block 234, and when the plug post 232 is inserted into the socket 410, the top block 234 abuts against the end face of the support leg 400, and there is a gap between the rubber sleeve 510 and the sliding wheel 230.

[0039] It should be noted that the universal wheel 231 can be installed on the support plate 233 by bolts, and then the support plate 233 is slidably installed on the slide 220. Furthermore, the top block 234 is integrally formed on the support plate 233, and the plug post is also located on the top block 234. The diameter of the top block 234 is smaller than the diameter of the support leg 400, but larger than the diameter of the socket 410. Furthermore, the distance that the rubber sleeve 510 extends beyond the end face of the support leg 400 is smaller than the height of the top block 234. In this way, when the plug post 232 is inserted into the socket 410, the top block 234 is connected to the support leg 400, and there is a gap between the rubber sleeve 510 and the top block 234 and the support plate 233. That is, when the chair legs 400 are installed with the sliding wheels 230 and have the sliding function, the rubber sleeve 510 is completely in a stress-free state, so that it can be ensured that the rubber sleeve 510 will not be crushed by the sliding wheels 230 when the chair is supported by the sliding wheels 230.

[0040] like Figure 6 As shown, in one embodiment, a slider 235 is further provided on the support plate 233 , and the slider 235 is slidably connected to the slide cylinder 220 .

[0041] It should be noted that, for example, the cross-section of the integral structure formed between the slider 235 and the support plate 233 is an I-shape, so that the slider 235 can be stably slidably connected to the slide cylinder 220.

[0042] like Figures 2 to 6 As shown, in one embodiment, the slide 220 includes a column 221 and a plurality of horizontal bars 222 , each of which is arranged at equal angles on the outer wall of the column 221 , and each horizontal bar 222 is provided with a slide groove 2221 so that the slider 235 can be slidably set in the slide groove 2221 .

[0043] It should be noted that the column 221 is slidably mounted on the bracket 100 along the vertical direction, and each horizontal bar 222 is fixed at an equal angle to the bottom of the column 221, and each horizontal bar 222 is distributed along the horizontal direction. Each horizontal bar 222 has a sliding groove 2221, which allows the slider 235 to be slidably mounted in the sliding groove 2221, so that the support plate 233 is slidably connected to the horizontal bar 222.

[0044] like Figure 1 As shown, in one embodiment, the bracket 100 includes a top ring 110, a shaft tube 120 and a plurality of support rods 130, each support rod 130 is arranged at an equal angle on the outer wall of the shaft tube 120, the top of each support rod 130 is connected to the top ring 110, the chair cushion 300 is arranged on the top ring 110, each support leg 400 is respectively arranged at the bottom of each support rod 130, the column 221 is slidably arranged in the shaft tube 120, and the rotating rod 210 is rotatably connected to the shaft tube 120.

[0045] It should be noted that the top end of each support rod 130 is welded and fixed to the top ring 110. And the top ring 110 is fixed to the bottom of the seat cushion 300 by bolts. Each support rod 130 is welded and fixed to the shaft tube 120 through a middle connecting rod, so that the shaft tube 120 is located in the middle position of each support rod 130. Each support leg 400 is located at the bottom of each support rod 130. Furthermore, in order to improve the structural strength of the bracket 100, each support rod 130 is provided with a reinforcement frame near the support leg 400, and this reinforcement frame can also allow the user to rest his feet when sitting on the seat cushion 300.

[0046] like Figure 1 As shown, in one embodiment, a rotary wheel 240 is provided on the top of the rotary rod 210. It should be noted that the rotary wheel 240 is fixedly mounted on the top of the rotary rod 210, so that the user can rotate the rotary wheel 240 to drive the rotary rod 210 to rotate.

[0047] like Figure 1 As shown, in one embodiment, the bracket 100 further includes a plurality of retaining shells 140 , one end of each retaining shell 140 is connected to the shaft cylinder 120 , and the other end of each retaining shell 140 is respectively connected to each support rod 130 , and each retaining shell 140 is respectively located above each horizontal bar 222 .

[0048] In this way, by using the blocking shell 140 to block the top of the horizontal bar 222, the user can be prevented from accidentally stepping on the horizontal bar 222 when using the chair; at the same time, the overall aesthetics of the chair can be effectively improved.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in the present invention can be understood to include but not be limited to locking and fixing with screws / screws and welding.
