Office Chair Fixed Iron Plate
Office chair fixed iron plates typically use angle bracket hardware connectors, with common types including L-shaped angle brackets and right-angle fixed iron plates, primarily used to enhance the structural stability of chairs.
Common Types and Functions
The core function of office chair fixed iron plates is to strengthen structural stability by connecting different components of the chair (such as chair legs and crossbars). Common L-shaped angle brackets and right-angle fixed iron plates are designed at 90 degrees, suitable for right-angle connection scenarios. For example, a 90-degree right-angle stainless steel thickened angle bracket can be fixed with screws at the junction of chair legs and crossbars, effectively distributing stress and preventing loosening or breakage due to long-term use. Some products are designed with matching five-star foot accessories for special structures like swivel chairs to accommodate rotation or movement needs, rather than using ordinary angle brackets.
Material and Specification Selection
In terms of materials, cold-rolled steel and stainless steel are mainstream choices. Cold-rolled steel angle brackets are cost-effective and suitable for general office settings; stainless steel angle brackets offer strong corrosion resistance, ideal for humid environments or long-term use requirements. Some products feature a thickened design (e.g., thickness exceeding 3mm), significantly improving load-bearing capacity and suitable for heavy users or high-intensity use scenarios. Specifications should match the chair's dimensions; for example, when the chair leg diameter is 30mm, an angle bracket with a corresponding hole spacing should be selected to avoid gaps or inability to secure after installation.
Price and Installation Considerations
Prices vary widely, ranging from 0.25 yuan for simple cold-rolled steel angle brackets to 105.8 yuan for high-end stainless steel thickened models, primarily influenced by material, thickness, and specifications. When installing, note three points:
- Hole Matching: Choose products with smooth, burr-free holes to avoid scratching hands or damaging the chair surface during installation;
- Screw Fixation: Use matching screws (e.g., M4 or M5 self-tapping screws) and tighten them to ensure the angle bracket fits snugly against the chair components, preventing loosening;
- Structural Testing: After installation, gently shake the chair to check the stability of the connections. If wobbling is detected, readjust the screws or replace with a larger-specification angle bracket.
Special Scenario Adaptation
For swivel chairs or office chairs with wheels, prioritize matching five-star foot accessories. These accessories typically integrate a rotating shaft and fixed structure, better adapting to dynamic stress requirements and preventing metal fatigue in ordinary angle brackets due to long-term twisting. If the chair is designed to be disassemblable, choose angle brackets with pre-installed holes to simplify the installation process and enhance stability after repeated disassembly and reassembly.
