Background
The chair with sufficient mechanical performance of inclination and reclining when leaning back is a chair with a backrest capable of inclining backwards at a large angle and allowing people to lean for lying and rest, and mainly comprises an inclined chair and a reclining chair. The rocking chair is a chair with a front-back rocking function. Compared with the common straight-back chair and stool, the tilting chair, the reclining chair and the rocking chair can tilt backwards at a large angle, and if the 3 chairs are unreasonable in design, the chairs are easy to tip over in the normal use process and hurt the user, so the stability is an important mechanical property of the chairs.
QB/T4783-: rocking chair was released in 2015 at 4-month and 30-month, and formally implemented in 2015 at 10-month and 01-month. The standard mainly provides a method for testing the stability of the rocking chair when the rocking chair leans backwards, and the standard is issued and implemented, so that the method has important significance for guiding enterprise production, standardizing the market and further improving the safety performance of furniture products. In this standard, the method for stability testing of the swing is: a loading tray having a mass of 10Kg was used, requiring a diameter of 350mm and a thickness of 48 mm. The 11 load disks are loaded against the back of the chair in the seat, and if necessary, the load disks can be secured using light weight cables. If the chair back is not high enough, a lightweight bar or plate may be used to prevent the loading tray from sliding off. Depending on the actual situation, the swing may be tilted forward as far as possible, or until the back support surface is perpendicular to the horizontal. Under the action of gravity, the rocking chair can freely rock backwards, and simultaneously, whether the chair is overturned or not can be recorded. Meanwhile, in this standard, the required measurement accuracy is: loading force: ± 5% of nominal value, angle: 2 degrees; loading disc position accuracy: 5 mm.
In the standard test method, the test precision has higher requirements, and the standard can use a light rope to fix the loading disc when necessary; if the chair back is not high enough, a test method that a light bar or a flat plate can be used for preventing the loading disc from sliding off is easy to cause the instability of the loading disc and the deviation of the position and the angle, so that the change of the loading force is caused, and the test result is influenced. Meanwhile, when the loading disc is stacked on the rocking chair, due to the fact that no auxiliary mechanism exists, the stacked loading disc is prone to tilting and collapsing, certain risks are caused to operating personnel, and meanwhile, the quality and the service life of the loading disc can be affected due to long-time falling damage.
