Product Overview

The Office Chair Backrest Push Testing Machine is an essential testing device in the furniture chair industry. It simulates the normal daily use of furniture to evaluate the strength of chair backrests after repeated load applications. The machine tests and determines whether the backrest can maintain normal functionality after being subjected to horizontal static and cyclic load tests. This testing machine employs closed-loop control to manage the force exerted by the cylinder for precise and consistent testing.

Product Application:

The Office Chair Backrest Push Testing Machine is a critical testing device for the furniture chair industry. It simulates real-life daily usage to evaluate the strength and performance of chair backrests under repeated loading conditions. This machine is used to test and determine whether the backrest can maintain normal functionality after being subjected to static and cyclic horizontal load tests. It adopts a closed-loop control system for the cylinder force, ensuring precise and reliable testing results.

Product Features:

1. Backrest Durability Testing:

Evaluates the durability of office chair backrests under repeated push-back motions.
Determines the maximum number of push cycles the backrest can endure, assessing its reliability over extended use.

2. Backrest Strength Testing:

Measures the maximum load capacity of the backrest when subjected to pushing forces.
Ensures the backrest meets strength requirements for safe and normal usage.

3. Connection Reliability Testing:

Examines the reliability of connections between the backrest and other components, such as the seat and armrests.
Ensures that these connections can withstand pushing forces without loosening or damage during usage.

4. Comfort Evaluation:

Some models of push testing machines simulate the shape and pressure distribution of the human back.
Provides insights into the comfort of the backrest, aiding in the design and improvement of office chairs.
