Dust-proof safety helmet used for tunnel construction and having dust prevention effect

Abstract

The invention provides a dust-proof safety helmet used for tunnel construction and having a dust prevention effect, and relates to the field of tunnel construction appliances. The problems that face masks and crash helmets commonly used in tunnel construction can not be connected together, the face masks are easy to loss, dust is easily accumulated on the face masks and the filtering effect is thus affected. The dust-proof safety helmet used for tunnel construction and having the dust prevention effect includes a convex-top protective shell, a head lamp is connected with the left side of the convex-top protective shell through bonding, a storage shell is bonded on the left side of the convex-top protective shell and located on the bottom of the head lamp, the bottom of the convex-top protective shell is provided with a through hole communicated with the inside of the storage shell, the inside of the storage shell is connected with a telescopic storage mechanism through bonding, and thelower portion of the convex-top protective shell is provided with an earshield. According to the dust-proof safety helmet used for tunnel construction and having the dust prevention effect, a face mask is fixed through the telescopic storage mechanism, a smooth impact block is arranged to hit against the face mask closely attached to an elastic cover to make dust on the surface of the face mask drop down, and it is avoided that dust is accumulated on the surface of the face mask and the dust filtering effect is thus affected.

Description

technical field [0001] The invention relates to the technical field of tunnel construction tools, in particular to a dust-proof safety helmet for tunnel construction with dust removal effect. Background technique [0002] During tunnel construction, the internal air flow is not easy to circulate. Once dust is formed, it will not disperse for a long time. Workers need to wear masks to carry out construction operations. Protective caps are an indispensable construction tool in tunnel construction. The existing tunnel construction uses protection The cap is just a headlight added to the safety helmet. It has a relatively simple function and is separated from the mask. The mask needs to be put on the face manually when using it. When the hands are dirty, it will affect the cleaning and dust filtering effect of the mask. When using and putting it down at the same time It is easy to cause the loss of the mask, and it is easy to accumulate dust during use, which will also affect th...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a dust-proof safety helmet for tunnel construction with a dust-removing effect, which solves the problem that the protective cap cannot prevent dust during tunnel construction, and the mask used is easy to lose, and has a dust-proof effect. Cap needs electric dust removal, increasing power consumption
