[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The invention discloses a chair with a gathered lumbar support, comprising a chair back 1 and a seat 101. A sleeve 103 is fixedly connected to one side of the back of the chair back 1. A folding assembly 2 is arranged at the lower end of the seat 101. The folding assembly 2 is composed of a vertical rod 201, a lumbar rod 202 and a supporting rod 204. The lumbar rod 202 is arranged in the sleeve 103. The upper end of the vertical rod 201 that passes through the seat 101 is sleeved with a kit 4, and the kit 4 is rotatably connected to the upper end of the lumbar rod 202.

[0025] Specific working principle and implementation method: The backrest 1 and the seat 101 form the basic shape of the chair, and a sleeve 103 is fixedly connected to one side of the back of the backrest 1, and a folding assembly 2 is arranged at the lower end of the seat 101. The folding assembly 2 is mainly composed of a vertical rod 201, a waist rod 202 and a support rod 204. The waist rod 202 is inserted into the sleeve 103 to support the backrest 1, and the upper end of the waist rod 202 is connected to the upper end of the vertical rod 201 through a kit 4. One end of the kit 4 is cylindrical and the other end is a round rod. The upper end of the vertical rod 201 is sleeved and connected by a round rod-shaped waist rod 202. The vertical rod 201 and the waist rod 202 can be rotated. The support rods 204 are combined and connected, and the support rods 204 can be rotated. The waist of the chair back 1 can be supported by the waist rod 202 and extends to the upper end. In this way, the designer can lean on the chair back 1 when sitting on the seat 101, and it can be stored by rotating between the support rod 204, the waist rod 202 and the vertical rod 201, and it is cylindrical after storage, saving storage space.

[0026] like Figure 2As shown, the two support rods 204 are cross-rotatably connected, and a connecting block 205 is slidably connected to the vertical rod 201. The connecting block 205 is a special-shaped block. The vertical rod 201 is slidably set on the connecting block 205, and two give-way cavities are provided on the connecting block 205. The ends of the support rods 204 vertically set on both sides are rotatably connected by pins, and the connecting block 205 is rotatably connected to the support rod 204. The lower end of the vertical rod 201 is plugged with a base 206, and the support rod 204 is rotatably connected to the base 206. The connecting rod 203 is rotatably connected to the base 206 away from the vertical rod 201. The number of support rods 204 is multiple, and the support rods 204 are rotatably connected. The lower end of the support rod 204 and the lower end of the vertical rod 201 are connected by a base 206. The vertical rod 201 and the base 206 are vertically plugged, and the support rod 204 and the base 206 are rotatably connected. By adding the base 206, the overall connection can be made more stable.

[0027] like Figure 1 and Figure 3 As shown, an armrest pad 102 is provided in the middle section of the chair back 1, and a connecting sleeve 104 is fixed to the lower end of the armrest pad 102, and the upper end of the connecting rod 203 is inserted in the connecting sleeve 104. The end of the armrest pad 102 away from the connecting sleeve 104 is penetrated by the lumbar rod 202, and the upper end of the connecting rod 203 is extended to both sides, and the whole is L-shaped. By arranging the armrest pad 102 in the middle section of the chair back 1, it is convenient for people to put their hands on the armrest pad 102 after sitting on the seat 101, which is convenient for people to rest.

[0028] like Figure 3 and Figure 4 As shown, the sleeve 103 is divided into three sections and is arranged on both sides of the back of the chair back 1 with equal spacing. The sleeve 103 is divided into three sections, wherein the two lower ends are through-type settings, and the upper end is a closed setting with equal spacing. The advantage of this design is that the chair back 1 can be supported more openly and the connection is more stable.

[0029] like Figure 1 As shown, protective cloth 105 is fixed on both sides of the lower end of the seat 101 away from the vertical rod 201. After the support rod 204 is stored, the protective cloth 105 can protect the rotating part, which can play a certain protective role.

[0030] like Figure 2 As shown, a non-slip pad is fixed to the lower end of the base 206. The purpose of fixing the non-slip pad at the lower end of the base 206 is to prevent the base 206 from scratching the ground during use. The non-slip pad can prevent the entire body from being displaced during use, and no harsh sound will occur when the entire body moves.

[0031] like Figure 2As shown, protective blocks 3 are fixedly connected to the support rods 204 on both sides by pins, and the protective blocks 3 are set against the lumbar bar 202; the protective blocks 3 are set on both sides of the support rods 204 by pins, and after the lumbar bar 202 is supported, the protective blocks 3 are against the lumbar bar 202, so that the lumbar bar 202 can be prevented from bending and deforming inward.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
