Abstract
The invention relates to the technical field of helmets, in particular to a helmet for building construction. The helmet for building construction comprises a shell and a peak connected onto the shell, a first airbag layer and a second airbag layer which are inflatable are sleeved outside the shell, the outer surface of the first airbag layer is corrugated, and the first airbag layer and the second airbag layer are communicated through a three-way inflation valve. The helmet for building construction in the technical scheme is capable of relieving impact force and avoiding potential safety hazards.
Description
Technical field
The present invention relates to the technical field of safety cap, be specifically related to a kind of safety helmet for building operation.
Background technology
In industry, civil buildings work progress; safety factor is a link can not be ignored, and therefore, people design various protection apparatus; such as safety clothes, safety cap etc.; can people play a very good protection, especially for the safety cap of protection human body head, its effect is particularly evident; the safety cap using in prior art; its structure, for being generally the some straps of tying-up in a cap shell, forms a supporting network, and the bongrace being connected with cap shell is flat.When hard thing strikes human body head; by distance between flexible and supporting network and the cap of strap, carry out shock absorbing; but the retractility of strap is limited; affect its firm degree; meanwhile, supporting network and head contact area are little, and impact power can not finely be disperseed; the protective effect that can not play human body head, still exists potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of safety helmet for building operation that slows down impulsive force, avoids potential safety hazard is provided.
In order to solve the problems of the technologies described above, the invention provides a kind of safety helmet for building operation, comprise cap shell and be connected to the bongrace on cap shell, described cap shell overcoat has the first air bag layer and the second air bag layer that can inflate, described the first air bag layer outer surface is bellows-shaped, and the first air bag layer and the second air bag layer adopt threeway charge valve to be communicated with.
Adopt the safety helmet for building operation tool of technique scheme to have the following advantages: outer surface is bellows-shaped the first air bag layer, when weight collides on the first air bag layer, bellows-shaped has increased contact area, impact power plays good dispersion force effect, the the second air bag layer impact power arranging can play further cushioning effect, the first air bag layer and the second air bag layer adopt threeway charge valve to be communicated with, can be by two air bag layers be inflated respectively, effectively control the inflated condition in two air bag layers, thereby the impulsive force that can produce the weight falling plays cushioning effect well, the protective effect that human body head is played, further avoided potential safety hazard.
As preferred version, in order further to reduce human body head, be subject to impulsive force, the inner surface of described cap shell arranges one deck buffering net.
As preferred version, consider when weight collides bongrace, in order to increase be connected with the cap shell thickness of position of bongrace, avoid the impulsive force of weight to destroy bongrace and cap shell connecting portion and hurt human body, the side structure of described bongrace is trapezoidal.
As preferred version, consider when female friend's hair is longer, conveniently hair is fixed, on described cap shell, one end relative with bongrace is provided with hair band net.
accompanying drawing explanation
Fig. 1 is the structural representation of safety helmet for building operation of the present invention;
In figure: 1-cap shell, 2-bongrace, 3-cushions net, 4-the first air bag layer, 5-the second air bag layer, 6-threeway charge valve, 7-hair band net.
the specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of safety helmet for building operation, comprise cap shell 1 and be connected to the bongrace 2 on cap shell 1, cap shell 1 overcoat has the first air bag layer and the 4 second air bag layers 5 that can inflate, the first air bag layer 4 outer surface are bellows-shaped, and the first air bag layer 4 and the second air bag layer 5 adopt threeway charge valve 6 to be communicated with, and the inner surface of cap shell 1 arranges one deck buffering net 3, the side structure of bongrace 2 is trapezoidal, and one end relative with bongrace 2 on cap shell 1 is provided with hair band net 7.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the premise without departing from the principles of the invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (4)
1. a safety helmet for building operation, comprise cap shell and be connected to the bongrace on cap shell, it is characterized in that: described cap shell overcoat has the first air bag layer and the second air bag layer that can inflate, described the first air bag layer outer surface is bellows-shaped, and the first air bag layer and the second air bag layer adopt threeway charge valve to be communicated with.
