Sanhe Office Chair Testing Equipment
The office chair testing equipment that may be involved in the Sanhe area mainly includes chair back recline durability testers, office chair rotation durability testers, office chair back-push durability testing machines, and office chair seat-back linkage testers. Their functions and application scenarios are as follows:
The chair back recline durability tester is mainly used to evaluate the structural stability of the chair back during long-term repeated recline movements. By simulating recline operations at different angles (e.g., 30ยฐ-90ยฐ) and speeds (e.g., 10-30 times per minute), this device can detect the wear and tear of the chair back frame, connectors (such as rivets and screws), and materials (such as metal and plastic). For example, if the chair back shows fractures or looseness after 50,000 cycles of testing, it indicates insufficient durability. Such equipment is suitable for product quality inspections of student desk chairs, office chairs, and other scenarios that require frequent reclining.
The office chair rotation durability tester is designed for the stability of the rotation function and can simulate tens of thousands of rotation operations (e.g., more than 100,000 times), focusing on detecting issues such as jamming, looseness, or shaking during rotation. Its core testing objects include the connection strength between the seat and the rotating shaft, the airtightness of the pneumatic lifting system (e.g., the air rod leakage rate), and the wear resistance of the base. For example, if there are obvious abnormal noises or changes in resistance during rotation, it may reflect insufficient lubrication of the rotating shaft or structural defects. This device is a key tool for verifying the quality of the rotation function of office chairs.
The office chair back-push durability testing machine is designed according to the QB/T 2280 standard. It evaluates the load-bearing capacity and durability of the chair back by simulating back-push movements (e.g., applying a dynamic load of 50-200 kg). It supports dynamic cycle testing (e.g., 10,000 cycles) and automated data collection, and can generate test reports containing parameters such as maximum load-bearing capacity and deformation rate, providing a basis for product design optimization (such as strengthening the chair back support structure). Such equipment is mostly used in the research and development and quality inspection of high-end office chairs or gaming chairs.
The office chair seat-back linkage tester simulates the combined load of the seat and back during daily use and evaluates their durability and comfort through thousands to tens of thousands of cycles of testing (e.g., 20,000 times). It can adjust the pressure (e.g., 50-150 kg) and angle (e.g., seat tilt of 0ยฐ-15ยฐ and back recline of 0ยฐ-90ยฐ) to test the coordinated performance of the seat and back under different postures (such as sitting upright and reclining). For example, if the seat shows sagging or the back elasticity decays after testing, it indicates that the structural design or material selection needs improvement. This device is an important tool for evaluating the overall performance of office chairs.
