What kind of structural design does the iron frame of single chair adopt?

The iron frame structural design of single chair is the key to its overall performance and beauty. Usually, it adopts a frame structure. The bottom frame is rectangular or trapezoidal. The rectangular frame can provide relatively stable horizontal support, while the trapezoidal frame adds a unique visual dynamic sense on the basis of stability. The edges and corners of the frame are mostly rounded, which not only avoids the accidental injury that sharp corners may cause to the user, but also softens the tough visual image of the iron frame to a certain extent.
As the key part of the support, the chair legs are generally designed with a certain inclination angle. This inclination is not arbitrary, but is precisely calculated so that when the chair bears the weight of the human body, the gravity can be evenly distributed along the chair legs to the ground. For example, the common inclination angle is between 5 degrees and 15 degrees. This range can give the chair an elegant posture while ensuring stability. The connection between the chair legs and the bottom frame is welded or high-strength bolted. Welding can ensure the integrity and firmness of the connection, while bolted connection is convenient for later disassembly and maintenance. If there is a problem with a chair leg, it can be easily replaced.
The backrest frame is connected to the seat frame to form an integrated mechanical support system. The backrest frame is often curved or slightly inclined straight. The curved backrest conforms to the natural curve of the human spine, can provide comfortable fit and support for the user's back, and reduce the fatigue of sitting for a long time. The straight backrest shows a simple and fashionable style with simple lines, which is suitable for a variety of modern home decoration styles. At the connection between the backrest and the seat, reinforcing ribs or special connecting components are used to enhance the structural strength here, because this is one of the parts where the pressure of the human body is more concentrated when using the chair.
The armrest frame is also an important part of the iron frame structure, if there is an armrest design. The armrest frame is generally connected to the seat and backrest frame, and its height and curvature are carefully designed to adapt to the natural position and posture of the human arm. The connection between the armrest frame and the main frame also focuses on firmness, and is fixed by welding or nesting bolts to ensure that when the user relies on the armrest, the armrest can stably withstand the corresponding force without shaking or loosening.
This iron frame structure design, through the reasonable layout of each component, precise angle control and firm connection method, not only provides reliable mechanical support for the single chair, ensuring the safety and comfort of the user in various actions such as sitting, leaning and holding, but also becomes a unique landscape in home decoration with its simple and design-rich shape.
