Technical Field

[0001] The present application relates to the field of product quality inspection equipment, and particularly to a helmet quality inspection device. Background Art

[0002] A helmet is a head protection device widely used in occasions such as engineering construction, road cycling, and sports competitions. A helmet mainly consists of a shell, a lining, and a suspension system, etc. The shell absorbs most of the impact force through deformation, the lining has a shock-absorbing function, and the suspension system is located between the shell and the lining and can usually be adjusted to adapt to the differences in the head shapes of different wearers. Since a helmet is a protective device, it is very necessary to perform quality inspection on the helmet during the production process.

[0003] Existing helmet quality inspection devices usually include types such as impact resistance inspection devices, puncture resistance inspection devices, abrasion resistance inspection devices, and extrusion resistance inspection devices, etc. When the helmet is subjected to different types of inspections, it is necessary to replace the inspection mechanism or the inspection head, which makes the operation process cumbersome and thus reduces the efficiency of helmet quality inspection.

[0004] Regarding the above related technologies, the inventor believes that when performing different types of inspections on the helmet, there are problems of cumbersome operation and low inspection efficiency. Utility Model Content
