Office Chair Anti-Explosion Cylinder
The office chair anti-explosion cylinder is a crucial component for ensuring the safety of office chair usage. Below is an introduction covering aspects such as price, material and certification, service life, and applicable scenarios:
Price: There are differences in the prices of office chair anti-explosion cylinders from different brands and types. For example, the anti-explosion hydraulic rod from Bazhou Junnan Furniture Factory is priced at 24.0 yuan; the Hengkang anti-explosion four-stage gas rod from Shaoxing Jinhang Home Furnishings Co., Ltd. is priced at 34.0 yuan; and the high-quality anti-explosion lifting rod for office chair accessories, available for wholesale from Anji Xinhui Office Chair Factory, is priced at 21.0 yuan. Consumers can choose according to their own budgets and needs.
Material and Certification: First-stage gas rods are mostly made of ordinary steel with relatively thin tube walls. Many of them lack basic certifications, and their explosion probability is 17 times that of third-stage gas rods, making them relatively less safe. Third-stage gas rods are made of titanium alloy material with thick tube walls and vacuum welding technology. They must pass international certifications such as SGS, and their anti-explosion pressure can reach 14 atmospheres, equivalent to 7 times that of car tires, offering high safety. Fourth-stage gas rods, building on the first and third stages, incorporate a high-temperature quenching process, significantly improving the metal's compressive strength and making them safer than third-stage gas rods.
Service Life: First-stage gas rods start to loosen after more than 30,000ๅ้ (lifting operations, assuming 'ๅ้' means lifting operations here; if not, please adjust accordingly), resulting in a relatively short service life. In contrast, third-stage gas rods have been tested to remain stable after 150,000 lifting operations, indicating a longer service life.
Applicable Scenarios: Due to their lower safety and shorter service life, first-stage gas rods are suitable for temporary use on construction sites or for individuals weighing less than 90 jin (45 kg). Third-stage gas rods, with their high safety and long service life, are suitable for individuals who work long hours or weigh more than 160 jin (80 kg).
Product Example: The Botai computer chair uses a fourth-stage anti-explosion cylinder, paired with three layers of steel plates and an alloy steel foot with a diameter of 70 centimeters. This design further enhances the stability and safety of the office chair.
