Description

Technical Field

[0001] This utility model provides a lightweight seat frame with a stable structure, belonging to the field of seat frame technology. Background Technology

[0002] In modern life, chairs are an indispensable tool in people's daily life, work and leisure activities, and the performance of their frame structure directly affects the user experience and safety.

[0003] Based on the above, the inventors discovered that:

[0004] In existing technologies, if we sit directly on an outdoor lawn, the grass sap will get on our clothes. On the one hand, in pursuit of lightness, the stability of the seat is often sacrificed, which can lead to problems such as swaying and tilting during use, affecting the safety and comfort of the user. On the other hand, the existing seat frame is not reasonably designed in terms of the connection structure between the backrest and the seat surface, making it inconvenient to install and disassemble.

[0005] Therefore, in view of this, we studied and improved the existing structure, and proposed a lightweight seat frame with a stable structure to solve the above-mentioned problems. Utility Model Content

[0006] The technical problem this invention aims to solve is that traditional lightweight seat frames with stable structures are unstable and inconvenient to install and disassemble.

[0007] To solve the above problems, the proposed technical solution is as follows: a lightweight seat frame with a stable structure, including a seat surface and a backrest. The seat surface is provided with a backrest support connection assembly, which includes two support rods, a reinforcing rod, a first support plate, a second support plate, and a limiting plate. The two support rods are located on both sides of the backrest, and the first support plate and the second support plate are located on the back of the backrest.

[0008] Furthermore, a rotating shaft is fixedly connected to the inner side of the support rod, and the other end of the rotating shaft is rotatably connected to the seat surface.

[0009] Furthermore, the limiting plate is fixedly connected to the chair surface and the rotating shaft is placed inside the limiting plate. The limiting plate is provided with a limiting groove and a limiting block is provided in the limiting groove. The limiting block is fixedly connected to the rotating shaft.

[0010] Furthermore, both support plate one and support plate two are fixedly connected to the chair surface, the support rods are backed against support plate one and the backrests are backed against support plate two, and support plate two is placed between the two support rods.

[0011] Furthermore, the reinforcing rod is placed between the two support rods and fixedly connected by bolt one, and the backrest is fixedly connected to the reinforcing rod by bolt two.

[0012] Furthermore, the chair surface is provided with a groove and the support rod is placed in the groove.

[0013] Due to the adoption of the above technical solution, the beneficial effects of this utility model of a lightweight seat frame with a stable structure are as follows:

[0014] 1. This utility model provides a stable support structure for the seat through the synergistic effect of the support rod, reinforcing rod, support plate one and support plate two in the backrest support connection assembly, making its structure more stable.

[0015] 2. The backrest and seat of this utility model are connected by a pivot, and with the setting of a limiting plate, limiting groove and limiting block, it is easy to install during use and easy to disassemble after use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The technical background of this application fully explains the problems of the prior art, and there are no overarching or general issues. The following utility model content and specific embodiments describe in detail the problems that this application needs to solve, clarify the technical problems that the technical solution needs to solve, and determine that the technical solution of this application has beneficial effects compared with the objective prior art.

[0026] Please see Figure 1-5 As shown: This utility model provides a lightweight seat frame with a stable structure, including a seat surface 1 and a backrest 2. The seat surface 1 is provided with a backrest support connection assembly, which includes two support rods 3, a reinforcing rod 4, a first support plate 5, a second support plate 6, and a limiting plate 7. The two support rods 3 are located on both sides of the backrest 2, and the first support plate 5 and the second support plate 6 are located on the rear side of the backrest 2. The first support plate 5 and the second support plate 6 are both fixedly connected to the seat surface 1. The support rod 3 rests against the first support plate 5, and the backrest 2 rests against the second support plate 6. The second support plate 6 is placed between the two support rods 3. A rotating shaft 8 is fixedly connected to the inner side of the support rod 3, and the other end of the rotating shaft 8 is rotatably connected to the seat surface 1.

[0027] like Figure 4 As shown, the limiting plate 7 is fixedly connected to the chair surface 1 and the rotating shaft 8 is placed inside the limiting plate 7. The limiting plate 7 is provided with a limiting groove 9 and a limiting block 10 is provided in the limiting groove 9. The limiting block 10 is fixedly connected to the rotating shaft 8, and the limiting plate is used to limit the limiting block.

[0028] The reinforcing rod 4 is placed between the two support rods 3 and fixedly connected by bolt one, and the back of the backrest 2 is fixedly connected to the reinforcing rod 4 by bolt two.

[0029] The chair surface 1 is provided with a groove 11 and the support rod 3 is placed in the groove 11.

[0030] The principle of this utility model for a lightweight seat frame with a stable structure is as follows:

[0031] In this utility model, the chair seat is fixedly connected to support plate one and support plate two, while the rotating shaft is fixedly connected to the support rod. The rotating shaft is rotatably connected to the chair seat, allowing the support rod to be rotated out of the groove.
