Abstract
The utility model discloses an air-permeable dual-protection safety helmet which comprises a cap shell, a cap hoop, a top belt, a back hoop and a lower jaw belt. A plurality of ventilation holes are formed in the top of the cap shell, a hollow reinforcing rib is pasted to the top of the cap shell and is covered on the outer side of the ventilation holes, and the side wall of the reinforcing rib is provided with a plurality of ventilation cases communicated with the ventilation holes. The air-permeable dual-protection safety helmet has the advantages that the hollow reinforcing rib is arranged on the top of the cap shell, head hurt caused by deformation of the safety helmet can be effectively prevented, and dual-protection effects are achieved; the ventilation holes are formed in the top of the cap shell, the external environment is communicated with the head in the safety helmet through the ventilation cases arranged on the side wall of the hollow reinforcing rib, and the head maintains to be ventilated and comfortable during a long period of time; and on the basis of ventilation maintenance, a winding non-direct-communication air channel is formed by the ventilation cases on the hollow reinforcing rib and the ventilation holes in the cap shell, and safety performance of the safety helmet can be effectively guaranteed.
Description
Technical field
The utility model relates to a kind of safety cap, is specially a kind of safety cap of ventilative, duplicate protection, belongs to the appliances for labor protection technical field.
Background technology
Safety cap is the protective articles that prevents alluvium injury head.Formed by cap shell, hat lining, jowl band and rear hoop.The cap shell is hemispherical, and is firm, smooth and certain elasticity arranged, and the impact and the puncture kinetic energy that hit thing are mainly born by the cap shell.Leave certain space between cap shell and the hat lining, available buffer, disperse instantaneous impact, thereby avoid or alleviate direct injury to head.When operation personnel head is subject to the impact of falling object; utilize safety helmet shell, hat lining first impulsive force to be decomposed on the whole area of cranium in moment; then utilize the structural deterioration of strain, plastic deformation and the permission of each position buffer structure of safety cap that most of impulsive force is absorbed; the impulsive force that is applied at last personnel's head is reduced to below the 4900N, thereby plays the effect of protection operating personnel's head.
There are the following problems for present safety cap: 1, safety cap is airtight, wears relatively for a long time and feels bad, and this also is many workmans one of reasons of timely safe wearing cap of being unwilling; 2, safety cap is mainly protected head by the cap shell, but under gravity impacted, the change of cap hull shape also easily caused head injuries.
The utility model content
The purpose of this utility model is for a kind of safety cap of ventilative, duplicate protection is provided, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of safety cap of ventilative, duplicate protection comprises cap shell, cap hoop, heading tape, rear hoop and lower jaw band; Described cap shell top is provided with some air-vents, and a hollow reinforcement sticks in cap shell top and covers on the outside of all air-vents, has some ventilation lattices that are communicated with in air-vent on the sidewall of reinforcement.
Be provided with sweatband on the described cap hoop, so that absorbing sweat.
Described cap shell is without the edge, edge or crimping is arranged.
The gap that 25 ~ 50mm is arranged between described cap shell and the hat lining, when object hit safety cap, the cap shell did not directly have influence on crown section because of stress deformation.
Described cap shell is ellipse or hemispherical, smooth surface, and when object fell on the cap shell, object can not stop immediately landing;
By the safety cap that technical solutions of the utility model design, have following beneficial effect:
1, is provided with hollow reinforcement at cap shell top, can effectively prevents the head injuries that causes because of safety cap deformation, play the effect of duplicate protection;
2, cap shell top is provided with air-vent, and the ventilation lattice by being arranged on hollow reinforcement sidewall is communicated with external environment with head in the safety cap, makes the head length time keep ventilative, comfortable.
3, keeping on the basis of breathing freely, the air-vent on the ventilation lattice on the hollow reinforcement and the cap shell consists of circuitous non-straight-through air duct, can effectively guarantee the security performance of safety cap.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is not pasted reinforcement;
Among the figure: 1, cap shell 2, reinforcement 3, air-vent 4, ventilation lattice.
The specific embodiment
Further set forth design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
The safety cap of a kind of ventilative, duplicate protection as depicted in figs. 1 and 2 comprises cap shell 1, cap hoop, heading tape, rear hoop and lower jaw band; Described cap shell 1 top is provided with the outside that some air-vent 3, one hollow reinforcements 2 stick in cap shell top and cover on all air-vents 3, has some ventilation lattices 4 that are communicated with in air-vent on the sidewall of reinforcement 2.
Be wound with sweatband on the described cap hoop, so that absorbing sweat.
Described cap shell 1 is without the edge, edge or crimping is arranged.
The gap that 25 ~ 50mm is arranged between described cap shell 1 and the hat lining, when object hit safety cap, the cap shell did not directly have influence on crown section because of stress deformation.
Described cap shell 1 is ellipse or hemispherical, smooth surface, and when object fell on cap shell 1, object can not stop immediately landing.
