A kind of double bolloon safety cap, be made up of cap body (1) and crown (2), illumination head lamp (8) is provided with in the front side of cap body (1), charger plug (9) is provided with at the dorsal part of cap body (1), it is characterized in that: between described cap body (1) and crown (2), be provided with partitioning slot (3), cap body (1) and crown (2) are linked together by multiple brace (4), and described brace (4) is easily broken structure; Arc air bag (7) is also provided with in cap body (1) inside; Be provided with air bag (7), controller (10) in crown (2) inside, be provided with arching pressure sensor (5) in crown (2) outside, described controller (10) includes control device and battery.
Description
Technical field
The utility model relates to a kind of labor protection apparatus, specifically a kind of double bolloon safety cap.
Background technology
In prior art, the essential labor protection apparatus in the field such as construction, underground work is engaged in by safety cap, and it effectively can be provided protection when labourer's head clashes into.Existing safety cap major constituents arranges one deck safety net in inside; at outer setting cap shell; when there being External Force Acting on cap shell; active force passes to human body head by safety net; safety net increases active area on the one hand; can also cushioning effect be played on the other hand, thus serve the effect of protection head.Name is called: the utility model technical scheme of airbag type safety cap (application number: 201220652331.X) is improved technique scheme; add " blasting air bag " in cap shell inside; when being subject to external force collision; " blasting air bag " can initiatively eject, thus plays the effect of protection head.But mainly there is following problem in this technical scheme: when 1, " blasting air bag " ejects, because safety cap top does not discharge outlet, all active forces all can act directly on head, and when " blasting air bag " self ejection power controls bad, its ejection process may cause damage to human body head.2, after external force clashes into safety cap, " blasting air bag " ejects, and now very possible safety cap comes off from head, and have if follow-up exotic to produce human body again and clash into, safety cap loses protective action.
Summary of the invention
The utility model is a kind of double bolloon safety cap, be made up of cap body and crown, illumination head lamp is provided with in the front side of cap body, charger plug is provided with at the dorsal part of cap body, be provided with partitioning slot between described cap body and crown, cap body and crown are linked together by multiple brace, and described brace is easily broken structure, when being subject to larger separating force between cap body and crown, brace can fracture automatically.Also be provided with arc air bag in cap body inside, gassy when this air bag normally uses, and contact with human body head; when there being External Force Acting on safety cap; by air bag, external force is delivered to human body head, can plays great cushioning effect, protection human body head is from shock.Air bag, controller is provided with in crown inside, arching pressure sensor is provided with in crown outside, described controller includes control device and battery, described pressure sensor can by pressure signal transmission to controller after being clashed into, controller judges whether to need to eject air bag according to pressure signal, if need to eject air bag, controller can control air bag and eject.When air bag ejects, himself inner inflatable, the separating force between cap body and crown increases, and brace ruptures automatically, and cap body is separated with crown, thus plays the effect of protection human body head.
As improvement, described brace material is ABS plastic, and by pasting portion and easy breaking off section forms, the portion that wherein pastes is for pasting with cap body, crown, and easy breaking off section easily ruptures when being subject to External Force Acting.ABS plastic combination property is better, and impact strength is higher, and chemical stability, pliability are good, itself and cap body and crown is adhered by potent glue, and when being subject to larger separating force between cap body and crown, brace can rupture automatically.
As improvement, the quantity of described brace is four, and is uniformly distributed.
As improvement, described controller also comprises power energy allocation device, and power energy allocation device can stop when battery electric quantity is less powering to illumination head lamp, only powers to control device, ensures that control device normally runs.
As improvement, the gas generator type of described air bag is triazo-compound gas generator.
The beneficial effects of the utility model are:
1, in air bag ejection process, good protective effect is had to human body head.In air bag ejection process, crown can be separated with cap body, the predominant intermolecular forces of air bag acts on crown, instead of act on human body head, and the active force of air bag is not act directly on human body head, but act on human body head by air bag, certain cushioning effect can be played.
2, air bag has better protective effect to human body after ejecting.After air bag ejects, cap body is still fixed on human body head, can play a protective role.Crown, air bag are still connected with cap body, if external force acts on the air bag of crown or ejection, just can act on human body head, can play better protective effect through the double buffering of air bag and air bag.
3, adopt arching pressure sensor, sensor area is large, and pressure acquisition information is accurate, effectively can prevent air bag bullet by mistake.

Specific as follows: cap body 1, crown 2, partitioning slot 3, brace 4, pastes portion 41, easy breaking off section 42, pressure sensor 5, air bag 6, air bag 7, illumination head lamp 8, charger plug 9, controller 10.
Detailed description of the invention
With reference to the accompanying drawings, a kind of double bolloon safety cap, is made up of cap body 1 and crown 2, illumination head lamp 8 is provided with in the front side of cap body 1, be provided with charger plug 9 at the dorsal part of cap body 1, illumination head lamp 8 provides electric energy by the battery in controller 10, and charger is charged the battery by charger plug 9.Be provided with partitioning slot 3 between described cap body 1 and crown 2, when cap body 1 is not separated with crown 2, partitioning slot 3 vision is checked and not obvious.Cap body 1 and crown 2 are linked together by multiple brace 4, and described brace 4 is easily broken structure, and when being subject to larger separating force between cap body 1 and crown 2, brace 4 can fracture automatically.Described brace 4 preferred material is ABS plastic, and by pasting portion 41 and easy breaking off section 42 forms, wherein paste portion 41 for pasting with cap body 1, crown 2, easy breaking off section 42 easily ruptures when being subject to External Force Acting.ABS plastic combination property is better, and impact strength is higher, chemical stability, and pliability is good, itself and cap body 1 and crown 2 is adhered by potent glue, and when being subject to larger separating force between cap body 1 and crown 2, brace 4 can rupture automatically.Arc air bag 7 is also provided with in cap body 1 inside; gassy when this air bag 7 normally uses; and contact with human body head; when there being External Force Acting on safety cap; by air bag 7, external force is delivered to human body head; can play great cushioning effect, protection human body head is from shock.The effect of this air bag 7 is similar to the safety net in conventional security cap, but its protection effect is better than safety net.Air bag 6, controller 10 is provided with in crown 2 inside, arching pressure sensor 5 is provided with in crown 2 outside, described controller 10 includes control device and battery, described pressure sensor 5 can by pressure signal transmission to controller 10 after being clashed into, controller 10 judges whether to need to eject air bag 6 according to pressure signal, if need to eject air bag 6, controller 10 can control air bag 6 and eject.When air bag 6 ejects, himself inner inflatable, the separating force between cap body 1 and crown 2 increases, and brace 4 ruptures automatically, and cap body 1 is separated with crown 2, thus plays the effect of protection human body head.The electric energy of controller 10 is provided by battery.Sodium azide (NaN in air bag 6
