AI Technical Summary
In the process of disassembling the liner of existing riot helmets, the threaded rod is located inside the helmet body, which makes rotation inconvenient and requires many turns, resulting in inconvenience in disassembly and assembly.
The device employs a fixing and disassembly mechanism, utilizing the compression and shrinkage grooves of a permanent magnet and a locking block to achieve rapid installation and disassembly between the helmet shell and the inner liner. The positioning platform and the linkage platform are compressed and squeezed together to fix the positioning platform and the locking block. The locking block is engaged with the bottom of the positioning platform to complete the fixation. The device is also fixed by setting an anti-detachment mechanism. The device is also fixed by setting an anti-detachment mechanism and the first permanent magnet to achieve rapid adsorption and fixation.
It enables quick installation and removal of the helmet shell and inner liner, simplifies the operation process, improves the efficiency of installation and removal, and enhances wearing comfort.
