Problems solved by technology

[0004] In the test method of the above standard, there are high requirements for the accuracy of the test, and the standard adopts "If necessary, use a light rope to fix the loading plate; if the back of the chair is not high enough, you can use a light rod or flat plate The test method of "preventing the loading plate from slipping" is likely to cause the loading plate to be unstable, and the position and angle will be shifted, which will cause changes in the loading force and affect the test results.
At the same time, when the loading trays are stacked on the rocking chair, because there is no auxiliary mechanism, the stacked loading trays are prone to tilt and collapse, which will cause certain risks to the operator. At the same time, the long-term falling damage will affect the quality and service life of the loading trays

Abstract

The invention provides a rocking chair mechanical property testing device and a testing method thereof. The device includes a base, a first connecting part is provided in the middle of the base, and second connecting parts are symmetrically provided on both sides of the first connecting part. The first connecting part is connected with a first limiting part, and the second connecting part is connected with a second limiting part; a loading plate is also included, and the loading plate is arranged above the base. Starting from the existing standards, the present invention provides a set of testing devices that meet the requirements of the standard. The present invention can effectively fix the position of the loading plate in the rocking chair during the mechanical performance test, ensuring that the entire process complies with the requirements of measurement accuracy in the standard; at the same time, the present invention The inventive device can effectively simulate the dynamic change trajectory of the force when a person is on the rocking chair, making the detection result more real and reliable.

Description

Technical field [0001] The present invention belongs to the technical field of furniture mechanical properties, and specific relates to a rocharge chair mechanical properties test device and a test method thereof. Background technique [0002] When fully rearward, there is a chair that tilches and reclining mechanical properties. The nature of the pool chair can be tilted backwards, which can provide people who are lie on a chair, mainly including tilting chairs and loungers. The rocking chair is a chair having a front and rear swing function. Compared with the ordinary straight back chair and stool, the tilt chair, the lounge chair, and the rocharge chair can be tilted backwards. If these three chairs are unreasonable, it is prone to tipming during normal use, causing harm to users. Therefore, stability is an important mechanical performance of such chairs. [0003] QB / T 4783-2015 "People's Republic of China Light Industry Standard: Rock Chair" was released on April 30, 2015, ...
