Description

Support for toy combustion test device and toy combustion test device Technical Field The utility model relates to the technical field of toy detection equipment. More particularly, the present utility model relates to a stand for a toy combustion test device and a toy combustion test device. Background In the toy production process, in order to ensure the use safety of children, a combustion test is required to be carried out on the toy so as to detect the performance of the toy under the combustion condition. However, existing toy combustion test devices have some problems during use. At present, the support structure of part of the test device is simpler, and the flexible position adjustment function is lacked. When the test is carried out, the position and the angle of the toy are difficult to accurately adjust according to the shapes, the sizes and the test requirements of different toys. For example, for some irregularly shaped toys, existing brackets may not be able to accurately place them in the proper combustion position, resulting in inaccurate results of the combustion test, which may not truly reflect the combustion performance of the toy. Especially plush toys, are of various sizes and shapes. In conducting the fire test, it is sometimes necessary to find multiple angles to conduct the fire test to fully evaluate the fire characteristics of the toy. However, the existing support and clamp can only clamp the toy in parallel, namely, the two clamps are on the same horizontal line, and the clamping mode cannot meet the multi-angle combustion test requirements of different shapes and special-shaped plush toys. When special angles such as the side surface and the inclined surface of the toy are required to be subjected to combustion test, the existing parallel clamping mode cannot enable the toy to be stably kept at the required angle, so that the accuracy and the integrity of the test are affected. The main reason for this problem is that existing designs of holders are mostly specific to a particular type or size of toy, lacking versatility and flexibility. The diversity of toys and the complexity of the trial are not fully accounted for in the design process. In addition, when the combustion test is required to be carried out on different parts, the existing bracket is difficult to quickly and accurately adjust the position, so that the test efficiency is greatly reduced.
