[0001] This application relates to the technical field of seating, and in particular to a rotating cross-legged chair. Background Technology

[0002] As an essential piece of furniture for daily office and study use, chairs are normally used with the user's feet on the ground. However, due to differences in leg length, some users' legs are left dangling in the air, causing discomfort and requiring optimization. Utility Model Content

[0003] To improve user leg comfort, this application provides a rotating cross-leg chair.

[0004] This application provides a rotating cross-legged chair, which adopts the following technical solution: A rotating cross-legged chair includes a stool and a base disposed under the stool. The stool and the base are connected by a connecting vertical rod. The connecting vertical rod is provided with a connecting ring sleeve. The connecting ring sleeve is circumferentially rotatably connected to the connecting vertical rod. The connecting ring sleeve is provided with a limiting member. The limiting member is used to abut against and act on the connecting vertical rod to limit the connecting ring sleeve in the vertical direction. The connecting ring sleeve is connected to an extension plate extending in the horizontal direction.

[0005] By adopting the above technical solution, an extension plate is added to the underside of the chair. The overall height of the extension plate is moderate. When the chair is too high, the user's legs can be placed on the extension plate during use, which provides better support and improves the comfort of use. In addition, the position of the extension plate can be rotated and adjusted according to the user's needs, which is quite convenient.

[0006] Preferably, the limiting member includes a limiting stud threaded to the connecting ring sleeve, and the end of the limiting stud is used to abut against the connecting vertical rod.

[0007] By adopting the above technical solution, the limiting stud achieves the effect of connecting and fixing the vertical rod.

[0008] Preferably, the connecting vertical rod has an annular groove in the middle, and the end of the limiting stud is used to be embedded in the annular groove.

[0009] By adopting the above technical solution, the cooperation between the annular groove and the limiting stud achieves a limiting effect in the vertical direction.

[0010] Preferably, the end of the limiting stud has a ball, which is embedded in the end of the limiting stud.

[0011] Preferably, the end of the limiting stud has a receiving groove for the ball to be inserted, and the end of the limiting stud is fixedly provided with a limiting sleeve sleeved on the outside of the ball, and the portion of the ball exposed outside the limiting sleeve is less than one-half.

[0012] By adopting the above technical solution, when rotating relative to each other, the balls will cooperate with the inner wall of the receiving groove, reducing the friction during relative sliding.

[0013] Preferably, the connecting ring is connected to the extension plate via a connecting bracket.

[0014] Preferably, the extension plate is slidably connected to the connecting frame in a positional manner.

[0015] By adopting the above technical solution, the position of the legs can be adjusted by sliding the extension plate.

Detailed Implementation

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1: Example 1 of this application discloses a rotating cross-legged chair, referring to... Figure 1 It includes a chair 100 and a connecting vertical rod 110 disposed on the underside of the chair 100. The connecting vertical rod 110 is provided with a connecting ring 111, which is rotatably connected to the connecting vertical rod 110.

[0032] Reference Figure 1 , Figure 2In this embodiment, the connecting vertical rod 110 can be a rod of fixed length or a telescopic rod with telescopic function. This embodiment uses a rod of fixed length as an example. A connecting ring 111 is sleeved on the connecting vertical rod 110. A limiting member is provided on the connecting ring 111, which abuts against the connecting vertical rod 110 to limit the connection ring 111 in the vertical direction. Specifically, the limiting member includes a limiting stud 112 threadedly connected to the connecting ring 111, the end of which abuts against the connecting vertical rod 110. In this embodiment, the connecting vertical rod 110 has an annular groove 113 in the middle, and the end of the limiting stud 112 is embedded in the annular groove 113. The end of the limiting stud 112 has a ball 115, which is embedded within the end of the limiting stud 112.

[0033] The end of the limiting stud 112 has a receiving groove 116 for the ball 115 to be inserted. A limiting sleeve 114 is fixedly fitted onto the outside of the ball 115 at the end of the limiting stud 112. The limiting sleeve 114 can be fixed to the end of the limiting stud 112 by welding, threading, or bonding. The radius of the limiting sleeve 114 is smaller than the radius of the limiting stud 112, so that there is no interference during tightening. Simultaneously, to limit the position of the ball 115, less than half of the ball 115 is exposed outside the limiting sleeve 114. When the limiting stud 112 slides relative to the connecting vertical rod 110, the ball 115 will slide relative to the inner wall of the annular groove 113. The presence of the ball 115 reduces the friction between the two.

[0034] Reference Figure 4 A connecting ring 111 is connected to an extension plate 120 extending horizontally. The connecting ring 111 is connected to the extension plate 120 via a connecting frame 121. The connecting frame 121 consists of two parallel support rods. A sliding sleeve 122 is fitted onto the support rods on the lower side of the extension plate 120. The extension plate 120 can slide relative to the support rods via the sliding sleeve 122. An abutting bolt 123 is provided on one of the sliding sleeves 122. When the abutting bolt 123 is tightened, it will abut against the support rod, thereby achieving a fixed effect and allowing adjustment of the horizontal extension position of the extension plate 120.

[0035] In other embodiments, multiple annular grooves 113 may be provided at intervals along the length of the connecting vertical rod 110, thereby adjusting the vertical height of the extension plate 120.

[0036] Example 2: The difference from Example 1 is that, referring to... Figure 5 , Figure 6 , Figure 7The base has a base cylinder 130 located outside the connecting vertical rod 110. The lower side of the connecting ring sleeve 111 has an inner groove 131 fitted onto the upper end of the base cylinder 130. An elastic element is provided in the inner groove 131. The part of the base cylinder 130 embedded into the inner groove 131 has a positioning groove 133 for the elastic element to be embedded. Multiple positioning grooves 133 are evenly distributed along the circumference.

[0037] Specifically, in this embodiment, the elastic element is an elastic sheet 132. Several elastic sheets 132 can be arranged circumferentially; in this embodiment, one elastic sheet 132 is used as an example. The elastic sheet 132 is an arc-shaped portion, and its extension direction is horizontal, allowing the arc-shaped protrusion of the elastic sheet 132 to be embedded in the positioning groove 133. To facilitate the embedding of the elastic sheet 132, the cross-section of the positioning groove 133 is also arc-shaped to accommodate the deformation of the elastic sheet 132. Simultaneously, a gap exists between the inner wall of the inset groove 131 and the outer wall of the base cylinder 130 to allow for the deformation of the elastic sheet 132. This gap allows the elastic sheet 132 to deform when it disengages from the positioning groove 133.

[0038] A fixing bolt 134 is also threaded horizontally on the outer wall of the connecting ring 111. The fixing bolt 134 is positioned opposite the elastic piece 132. Each positioning groove 133 has a fixing hole 135 at its bottom. When the elastic piece 132 is inserted into the positioning groove 133, the fixing bolt 134 is facing the fixing hole 135 of the other positioning groove 133. Then, the fixing bolt 134 is screwed in so that the end of the fixing bolt 134 is inserted into the fixing hole 135, thereby achieving complete fixation in the circumferential direction.

[0039] Without the fixing bolt 134, the elastic sheet 132 can serve as a positioning element to achieve initial fixation, while the fixing bolt 134 can completely fix it in the circumferential position.

[0040] In other embodiments, refer to Figure 8 A support foot 140 can also be installed on the lower side of the extension plate 120. Rollers or other devices can also be installed on the support foot 140 or the lower side of the stool foot. They can be installed or replaced according to actual needs.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
