Description

Technical Field

[0001] This utility model relates to the field of office chair technology, and in particular to a reclining and stable office chair. Background Technology

[0002] As office settings and home needs converge, reclining office chairs are gradually becoming mainstream products. Their core function is to meet users' needs in various scenarios such as working, taking a lunch break, and relaxing by adjusting the backrest angle. Stability is achieved when reclining.

[0003] Most existing chairs rely on manual locking mechanisms, requiring users to operate the positioning components separately after adjusting the backrest angle, which is redundant. Furthermore, some devices use a single-point latching structure with insufficient locking strength. When lying down, the chair may loosen slightly due to the pressure of the user's weight, causing the backrest to slowly slide down or sway sideways, posing a safety hazard. The independent operation of the structure is cumbersome and has poor adaptability.

[0004] Therefore, it is necessary to provide a reclining, stable office chair to solve the above-mentioned technical problems. Summary of the Invention

The positioning structures are used to support and position the internal structure of the component, and protective baffles are installed at both ends of the support structure.

[0010] Preferably, the elastic component includes a telescopic support member, which is installed on the inner wall of the side end of the support and positioning component. An elastic element is installed on the side end of the telescopic support member. The telescopic support member, in conjunction with the elastic element, can be used to elastically reset the internal structure of the support and positioning component.

[0011] Preferably, the dynamic clamping assembly includes a guide plate, a main sliding structure, and an arc-shaped guide member. Sliding secondary sliding structures are located at both ends of the guide plate. Mounting frames are installed on the sides of the main and secondary sliding structures.

[0013] Compared with related technologies, the reclining and stable office chair provided by this utility model has the following beneficial effects:

[0014] This utility model provides a reclining and stable office chair. During use, to ensure the overall stability of the chair, a combination of a support positioning component and a support stabilizing component allows for rapid structural positioning after backrest adjustment, forming rigid support and effectively resisting lateral and overturning forces when reclining, significantly improving the overall stability of the chair.

[0025] The seat assembly 1 includes, but is not limited to, a modular splicing structure and a suspended elastic structure; in this embodiment, the seat assembly 1 preferably has a modular splicing structure.

[0026] The backrest assembly 2 includes a rotating frame 21 and a backrest workpiece 23. An adjustment component 22 is installed on the inner wall of the rotating frame 21. The adjustment component 22 is used to adjust the angle of the internal structure of the backrest workpiece 23.

[0027] When in use, the backrest assembly 23 can be easily and conveniently adjusted in angle using the adjustment component 22 at the bottom to meet the user's needs and provide ease of use.

[0028] The backrest assembly 2 includes, but is not limited to, segmented adjustment components and elastic mesh structures; in this embodiment, the backrest assembly 2 preferably has an elastic mesh structure.

[0029] The support and positioning component 3 includes a support structure 31, with positioning structures 32 sliding at both ends of the support structure 31. The positioning structures 32 are used to support and position the internal structure of the stabilizing component 6. Protective baffles 33 are installed at both ends of the support structure 31.

[0030] To ensure the structural stability of the entire seat, the positioning structures 32 at both ends of the inner wall can easily support and stabilize the components 6 for structural positioning and clamping, thereby ensuring the stability of the structure during use.

[0031] The support and positioning component 3 includes a toothed disc meshing structure and a fixed groove limiting structure; in this embodiment, the support and positioning component 3 preferably has a fixed groove limiting structure.

[0032] The elastic component 4 includes a telescopic support 41, which is installed on the inner wall of the side end of the support and positioning component 3. An elastic element 42 is installed on the side end of the telescopic support 41. The telescopic support 41, in conjunction with the elastic element 42, can be used to elastically reset the internal structure of the support and positioning component 3.

[0033] When the internal dynamic clamping component 5 slides and loosens, the telescopic support component 41 and elastic component 42 at both ends can easily and conveniently spring open the support positioning component 3 to provide stable support for the structure.

[0034] Among them, the elastic component 4 includes, but is not limited to, a spring positioning structure and a silicone elastomer structure; in this embodiment, the elastic component 4 is preferably a spring positioning structure.

[0035] The dynamic clamping assembly 5 includes a guide plate 51, a main sliding structure 52, and an arc-shaped guide member 59.

The friction clamping structure 58 is used for the friction clamping of the arc-shaped guide member 59.

[0036] To facilitate the structural positioning and clamping of the entire seat, the arc-shaped guide 49 at the side end will slide to the inner wall of the friction clamping structure 58 as the backrest assembly 2 is adjusted. Then, the friction clamping structure 58 will pre-limit the arc-shaped guide 49 and, under continuous squeezing and adjustment, will slide the main sliding structure 52. Subsequently, the connecting structure 55 with rotational function at both ends will simultaneously slide from the sliding structure 53 to disengage the fixed rod workpiece 56 from the inside of the support positioning assembly 3.

[0041] The working principle of the reclining and stable office chair provided by this utility model is as follows:

[0042] When the chair needs to be adjusted to a reclining position during use, the backrest assembly 2 is first adjusted to the desired angle. At this time, the dynamic locking assembly 5 at the bottom is pre-positioned inside the assembly and the assembly structure is released during the adjustment process. Subsequently, the internal structure of the support positioning assembly 3 is elastically deformed by the elastic assembly 4 to spring the positioning component open. After the backrest assembly 2 is adjusted to the appropriate angle position, the support stabilizing assemblies 6 at both ends of the bottom are rotated and locked onto the inner wall of the support positioning assembly 3 to form a rigid structural support, preventing the structure from loosening during use. After use, the support positioning assembly 3 can be locked in place by the internal dynamic locking assembly 5 to reduce the space occupied later.

[0043] Compared with related technologies, the reclining and stable office chair provided by this utility model has the following beneficial effects:

[0044] To ensure the stability of the seat during use, the supporting positioning component 3 and the supporting stabilizing component 6 work together to quickly achieve structural positioning after the backrest adjustment, forming a rigid support that effectively resists lateral and overturning forces when lying down, significantly improving the overall stability of the seat. Furthermore, when stabilizing the seat structure, the supporting positioning component 5 automatically pops open with the backrest adjustment, eliminating the need for manual operation and achieving a positioning effect upon adjustment. This simplifies the user's operation process and improves ease of use. Additionally, after use, the supporting component can be automatically retracted via elastic components, preventing exposed components from occupying extra space.
