Description

Safety helmet

Technical Field

The utility model belongs to the technical field of overhaul tool, concretely relates to safety helmet.

Background

The safety helmet is a shallow round top hat worn for protecting the top of the head and used for preventing impact objects from injuring the head, and generally comprises a helmet shell, a lower cheek band, a rear hoop and the like. Wherein, the cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the object to be struck are mainly born by the cap shell. During the ground inspection of an aircraft, it is often necessary to wear safety helmets.

However, some safety helmets used on the market today are not convenient enough to use, and have the following problems:

1. the lower cheek band, the rear hoop and the like are troublesome to wear and have poor comfort.

2. The buffering performance is general.

3. The usage is single.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a safety helmet, this safety helmet simple structure, convenient to use just wears comfortablely, and shock-absorbing capacity is good.

A safety helmet comprises a helmet shell. An elastic rubber layer is arranged on the inner wall of the cap shell, a sponge layer is arranged on the inner wall of the elastic rubber layer, and a plurality of springs are arranged between the sponge layer and the elastic rubber layer; and the inner wall of the sponge layer is provided with a loose and tight wool weaving layer.

Furthermore, the cap edges at the left side and the right side of the cap shell are respectively hinged with earmuffs, and the earmuffs are provided with elastic buckle belts; the outer walls of the left side and the right side of the cap shell are respectively provided with a fixing buckle; the fixing buckle is matched with the elastic buckle belt.

Furthermore, a telescopic pipe is arranged at the top of the cap shell, and a lighting device is arranged on the telescopic pipe; the top of the cap shell is also provided with a battery box; the battery box is electrically connected with the lighting device.

Further, the lighting device is an LED lamp.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model provides a safety helmet no longer adopts lower cheek area and back hoop isotructure, changes into elasticity wool weaving layer structure, wears convenient and comfortable. After the safety helmet is worn, the elastic wool weaving layer can be automatically tightened or loosened according to the size of the head, so that the safety helmet can be attached to the head without adjusting the lower cheek band and the rear hoop.

2. The elastic rubber layer can play the roles of insulation, shock absorption and impact resistance.

3. The spring and the sponge layer can further play a role in shock absorption and impact resistance, and meanwhile, the wearing comfort level is improved; the sponge layer can also play a role in ventilation and heat preservation, and is very suitable for being used at night or in cold weather.

4. The earmuffs are designed, so that the earmuffs can be turned up and down and are fixed through the fixing buckles and the elastic buckle belts; under the condition of cold or high noise, the earmuffs can be put down to cover ears, keep out the cold or block the noise, and reduce the situations that the earmuffs or the earplugs need to be additionally found in the maintenance process of the airplane; when the earmuffs are not needed, the earmuffs are fixed on the outer wall of the helmet shell by the fixing buckles and the elastic buckling belts, and the use is convenient.

5. Due to the design of the lighting device, the airplane can be lighted without carrying a flashlight in the dark environment (such as at night) maintenance work; the design of the telescopic pipe can also stretch and adjust the position of the lighting device at will, is convenient to use and can irradiate any required position.

Drawings

Fig. 1 is a cross-sectional view of a safety helmet described in the present invention.

Description of reference numerals:

the cap comprises a cap shell 1, an elastic rubber layer 2, a sponge layer 3, an elastic wool weaving layer 4, a spring 5, an earmuff 6, an elastic buckling belt 7, a fixing buckle 8, an extension pipe 9, a lighting device 10 and a battery box 11.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to the attached fig. 1 of the specification, the present invention relates to a safety helmet, which comprises a helmet shell 1. An elastic rubber layer 2 is arranged on the inner wall of the cap shell 1, a sponge layer 3 is arranged on the inner wall of the elastic rubber layer 2, and a plurality of springs 5 are arranged between the sponge layer 3 and the elastic rubber layer 2; and the inner wall of the sponge layer 3 is provided with a loose and tight wool weaving layer 4.

Preferably, but not limited to, ear muffs 6 are hinged to the brim of the left and right sides of the cap shell 1, and elastic buckle belts 7 are arranged on the ear muffs 6; the outer walls of the left side and the right side of the cap shell 1 are respectively provided with a fixing buckle 8; the fixing buckle 8 is matched with the elastic buckle belt 7.

Preferably, but not limited to, the top of the cap shell 1 is provided with a telescopic pipe 9, and the telescopic pipe 9 is provided with a lighting device 10; the top of the cap shell 1 is also provided with a battery box 11; the battery box 11 is electrically connected to the lighting device 10. Preferably, but not limited to, the lighting device 10 is an LED lamp.

The utility model discloses a use method does:

directly will the utility model provides a safety helmet cover is overhead, and layer 4 is knitted to elasticity wool and the head laminating, and layer 4 is knitted to elasticity wool can be according to the big or small automatically regulated elasticity of head (wear the safety helmet, and the head is knitted layer 4 and is outwards pushed open with the elasticity wool, and elastic deformation takes place for sponge layer 3 and spring 5 thereupon, takes off the safety helmet, and layer 4 resumes initial condition is knitted to sponge layer 3, spring 5, elasticity wool. When the user is in cold or has large noise, the ear muffs 6 can be put down to cover the ears; when the ear muffs 6 are not needed, the ear muffs 6 can be turned upwards, the elastic buckle belt 7 on the ear muffs 6 is buckled on the fixing buckle 8 on the helmet shell 1, and the ear muffs 6 are fixed on the outer wall of the helmet shell 1.
