A protective cover base and its safety helmet

Abstract

The invention discloses a protective cover base and a safety helmet thereof. The protective cover base includes a protective mirror mechanism and a locking mechanism, and the protective mirror mechanism is fastened to the locking mechanism. The inner walls on both sides of the protective mirror mechanism are formed with The lens protrudes, and the locking mechanism includes a sliding lock groove assembly and an unlocking projection, the unlocking projection is connected to the end of the sliding lock groove assembly, and the locking mechanism locks the protective mirror mechanism by hooking the lens projection through the sliding lock groove assembly , so as to realize the locking of the protective mirror mechanism; press down the unlocking projection to move the sliding lock groove assembly downward, so that the lens protrusion can be separated from the sliding lock groove assembly, thereby realizing the unlocking of the protective mirror mechanism, and the protective mirror mechanism faces outward Pulling can also make the lens protrusion out of the position of the sliding lock groove assembly, so as to realize the disassembly of the protective mirror mechanism. During the whole operation process, there is no need to waste energy and cost to teach people to operate, and reduce cost input.

Description

technical field [0001] The invention relates to the technical field of helmets, in particular to a protective cover base and a safety helmet thereof. Background technique [0002] A helmet is a protective gear used to protect the head, and it is an indispensable tool in people's traffic. Especially when driving a motorcycle, it is very important to wear a helmet. [0003] In the prior art, a transparent lens is usually installed in front of the helmet. Through this transparent lens, the driver can see the road conditions ahead more clearly, and it can also play the role of blocking wind, sand or dust. , but the existing lenses can only be firmly fixed on both sides of the helmet, which is very inconvenient to disassemble, so people have designed an unlocking and locking device that can lock the helmet lenses. The existing unlocking and locking devices have some Disadvantages: [0004] The structure of the existing unlocking and locking device is relatively complicated. The...

Problems solved by technology

[0003] In the prior art, a transparent lens is usually installed in front of the helmet, through which the driver can see the road conditions ahead more clearly, and can also play the role of blocking wind, sand or dust , but the existing lenses can only be firmly fixed on both sides of the helmet, which is very inconvenient to disassemble, so people have designed an unlocking and locking device that can lock the helmet lenses. The existing unlocking and locking devices have some Disadvantages:

[0004] The structure of the existing unlocking and locking device is relatively complicated. The process of locking and unlocking requires a lot of energy and manpower to learn how to operate, which increases the cost of manual operation and learning, and also consumes a lot of manpower and energy, and the operation is very troublesome. Improper operation will cause serious damage to the helmet, causing the helmet to be scrapped
