Equipment for detecting durability of castors of office chair

Abstract

The invention relates to equipment for detecting the durability of castors of an office chair, and the equipment comprises a platform (1), a sliding rail (2) disposed on the platform (1), a transmission arm in sliding connection with the sliding rail (2), a driver (3) for driving the transmission arm to make reciprocating motion along the sliding rail (2), a controller in communication connection with the driver (3), and a balance weight mechanism in connection with the mechanical arm. The balance weight mechanism comprises a balance weight object (4) and a balance weight rod (5), and the balance weight rod (5) is connected with the balance weight object (4). The lower part of the balance weight rod (5) is bulged from the bottom of the balance weight object (4). During operation, the lower part of the balance weight rod (5) is slidingly connected with the transmission arm in a vertical direction, and the bottom of the balance weight rod (5) is in fixed plugging connection with a slot of an office chair pedestal (12). Compared with the prior art, the equipment is high in reliability of the detection result, is high in efficiency, and is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of inspection, testing and certification, and in particular relates to an office chair caster durability testing device. Background technique [0002] The casters of office chairs generally use universal wheels and are set on the base. The seat is fixed in the socket of the base through the air pressure rod. The reliability during use has an important impact on the customer experience, so it is necessary to test the durability of the office chair casters, test whether the casters are easy to loosen and fall off, whether the rotation is flexible, whether the sliding is smooth and smooth, whether it is easy to damage, and the noise level how to wait. [0003] The office chair caster durability test equipment is to simulate the state of the human body sitting on the chair through the counterweight, push the chair to move back and forth, and last for a certain period of time to test the durability of the caster...

Problems solved by technology

[0003] The office chair caster durability test equipment is to simulate the state of the human body sitting on the chair through the counterweight, push the chair to move back and forth, and last for a certain period of time to test the durability of the caster, but some of the existing technologies will be equipped with Place the heavy object on the seat, fix the test tool and the office chair, and test the office chair and counterweight through the cylinder. This test method is difficult to fix the counterweight, and the position of the counterweight cannot be guaranteed for each test. Consistent, only by visual inspection, this test requires the office chair to perform more reciprocating motions (tens of thousands), during the back and forth movement of the office chair, due to inertia, the placement position of the counterweight will also change, which will cause Affect the consistency of test results

Others, such as disclosed in CN202195944U, use the seat to be removed, and a load-bearing box is set on the air pressure rod (seat air pressure rod), the bottom of the load-be
