Multi-layer protection combined type helmet convenient to disassemble and assemble

Abstract

The invention discloses a multi-layer protection combined helmet convenient to disassemble and assemble. The multi-layer protection combined helmet comprises: a protection shell, wherein the protection shell is the protection shell of the helmet, the outer wall of the protection shell is provided with a helmet lens, and the protection shell is internally provided with an air filtering sheet; a connecting sheet connected to the outer side of the air filtering sheet in an attached mode, wherein a connecting rod is fixedly connected to the side of the connecting sheet, a torsion spring is connected to the outer portion of the connecting rod in a nested mode, and a connecting base is connected to one end of the torsion spring; and a first protection layer mounted on the inner wall of the protection shell, wherein a telescopic spring is mounted in the first protection layer. According to the invention, the multi-layer protection combined type helmet convenient to disassemble and assemble is provided with a limiting block and a hook-and-loop fastener, the first protection layer and the second protection layer are separated through stretching and retracting of the limiting block, then the second protection layer is convenient to disassemble, assemble and replace, and the air filtering sheet is arranged to filter particulate matter in inhaled air so that the helmet has an anti-haze effect.

Description

technical field [0001] The invention relates to the technical field of helmets, in particular to a multi-layer protective combined helmet that is easy to assemble and disassemble. Background technique [0002] Because of its relatively hard protective shell, helmets are widely used in outdoor sports and high-risk work to protect the wearer's head and reduce the damage to the wearer's head when accidents occur. [0003] A helmet with a publication number of CN207784406U includes a helmet body and a lower jaw. Rotation hinges are provided on the rear parts of both sides of the helmet body, and pivot joints are arranged on the rear parts of the lower jaw. The mandible is lifted and fixed, which improves the previous situation that the mandible is not firmly fixed, and it is easy to loosen and affect the driver. [0004] The helmet mainly uses the structure of the chassis and the clip to improve the previous situation that the lower jaw is easy to slide down and the lower jaw i...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a multi-layer protective combined helmet that is easy to disassemble and assemble, so as to solve the difficulty in disassembling and assembling the inner lining during the daily use of the helmet proposed in the above background technology, and then it is difficult to remove the inner lining Clean and replace, and at the same time, in haze weather, there are still some deficiencies in the filtration of inhaled air, which in turn brings certain limitations to the use of helmets
