Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view in another direction of fig. 1.

In the figure: the hat comprises a hat shell body 1, air holes 2, a second-order hat brim group 3, a hat lining 4, a buffer layer 5, a fixing net 6, a woven belt 7, a fixing strip 8, a central anti-skid pad 9, a connecting belt 10 and a reinforcing plate 11.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, a ventilative safety helmet of big brim of a hat of buffering striking, including cap shell body 1, 1 side of cap shell body be equipped with a plurality of bleeder vent 2, be equipped with second order brim of a hat group 3 on the cap shell body 1, 1 inside cap liner 4 that is equipped with of cap shell body, be equipped with buffer layer 5 between cap liner 4 and the cap shell body 1, buffer layer 5 be located the inner wall of cap shell body 1, just cap liner 4 and buffer layer 5 between have the space.

The safety helmet can play a better role in protecting the head of a user when the head of the user is injured by falling objects or other external impacts, and thus, is widely used in various industries, the safety helmet in the present embodiment has a higher safety performance than the conventional safety helmet, a buffer layer 5 is arranged between the cap liner 4 and the cap shell body 1, the buffer layer 5 adopts polyurethane or polystyrene foam plastics, when external force impacts the cap shell body 1, before the cap shell body 1 contacts with the head, the buffer layer 5 in the cap shell body 1 contacts with the cap liner 4, in the process that the buffer layer 5 is contacted with the cap liner 4, the buffer layer 5 deforms, partial energy generated by impact is absorbed, when the cap shell body 1 is broken, the generated fragments fall on the buffer layer 5, so that the fragments are prevented from hurting the head of a user, and the harm of the cap shell body 1 to the head of the user is reduced. A gap is formed between the cap liner 4 and the buffer layer 5, when the helmet is used, the cap liner 4 is in direct contact with the head, and a gap is formed between the buffer layer 5 and the head, so that the air permeability inside the helmet is improved.

As shown in fig. 1, in this embodiment, the cushioning layer 5 is fixedly bonded to the inner wall of the helmet shell body 1, a fixing net 6 is disposed on one side of the cushioning layer 5 close to the helmet liner 4, and the fixing net 6 is tightly attached to the cushioning layer 5.

The fixing net 6 is closely attached to the cushioning layer 5, preventing the cushioning layer 5 from falling off from the inner wall of the cap shell body 1, resulting in that the cushioning layer 5 is not enough to protect the head of the user.

In this embodiment, the fixing net 6 comprises a plurality of woven belts 7, the woven belts 7 are distributed annularly along the inner wall of the hat shell body 1, and the woven belts 7 are connected with a plurality of fixing strips 8.

The meshbelt 7 uses the high strength's rubber band, will prevent that buffer layer 5 from closely laminating on buffer layer 5, hinders the deformation that buffer layer 5 and cap shell body 1 both take place because of external force impact.

In this embodiment, the fixing strips 8 are distributed along the radial direction of the woven belt 7, and the fixing strips 8 and the woven belt 7 are distributed in a staggered manner.

The fixing strip 8 is made of soft plastics, fixes and stabilizes the mesh belt 7, prevents the excessive deformation of the mesh belt 7, supports the cap shell body 1, and reduces the fragmentation of the cap shell body 1 caused by deformation.

In this embodiment, buffer layer 5 is flexible material, just buffer layer 5 on distribute and have a plurality of air vent, the air vent outwards extend to and run through cap shell body 1.

The buffer layer 5 is made of polyurethane or polystyrene foamed plastic, and the inside of the cap shell body 1 is communicated with the outside, so that the air permeability inside the cap body is enhanced.

In this embodiment, the hat lining 4 includes a central non-slip mat 9, a plurality of connecting bands 10 are distributed around the central non-slip mat 9, the connecting bands 10 are fixedly connected with the hat shell body 1, and the plurality of connecting bands 10 are distributed equidistantly along the circumference of the central non-slip mat 9.

The connecting band 10 fixes the cap liner 4 on the cap shell body 1, reduces the relative displacement of the cap liner 4 in the cap shell body 1, and enhances the stability of the cap liner 4. The cap shell body 1 is also connected with a movable buckle at the lower jaw, so that the tightness degree of the shell body can be conveniently adjusted, and the cap shell is attached to the head of a user.

In this embodiment, the central anti-skid pad 9 is located at the center of the cap lining 4, and the central axis of the central anti-skid pad 9 coincides with the central axis of the cap shell body 1.

The central anti-skid pad 9 is in direct contact with the head of a user, so that the phenomenon that the helmet shell body 1 slides due to the fact that the friction force between the helmet liner 4 and the head is too small, and the main position of the head of the user cannot be protected by the helmet is avoided.

As shown in fig. 2, in the present embodiment, the second-order visor group 3 is fixedly connected to the edge of the hat shell body 1, and the thickness of the second-order visor group 3 close to the hat shell body 1 is greater than the thickness of the second-order visor group 3 far from the hat shell body 1.

The second-order brim group 3 increases the width of the peripheral edge of the hat to 45-60 mm, and compared with the width of the brim of the traditional safety helmet, the second-order brim group increases the protective covering surface, has larger protective area for users and higher safety factor.

In this embodiment, the outer wall of the cap shell body 1 is provided with a reinforcing plate 11, and the reinforcing plate 11 extends to be connected with the second-order brim group 3.

Reinforcing plate 11 and second order brim of a hat group 3 are connected, and reinforcing plate 11 slope or be vertical direction setting, when receiving from the top down impact force on cap shell body 1, can play certain supporting role, reduce the ascending impact force of vertical side, reduce the striking injury to user's head.

In this embodiment, the reinforcing plate 11 is disposed obliquely, the reinforcing plate 11 is fixedly connected to the cap shell body 1, and the thickness of the joint between the reinforcing plate 11 and the cap shell body 1 is greater than that of the cap shell body 1.

The reinforcing plate 11 is located the user forehead with the cap shell body 1 junction, and junction thickness is greater than the thickness of cap shell body 1, under the too big condition of outside impact, prevents that the cap shell body 1 from taking place the fracture, avoids the head to receive direct striking, receives serious damage.

The utility model discloses a theory of operation is: establish the user head with 1 cover of cap shell body, make central slipmat 9 on the cap liner 4 be located the top of the head, adjust the position of cap shell body 1, guarantee the primary importance of cap shell body 1 protection user head, when cap shell body 1 receives external force striking, external acting force makes 1 deformation of cap shell body and with buffer layer 5 striking on user head surface, this in-process, buffer layer 5 takes place deformation and contacts with the user, avoid the striking that 1 direct lead to of cap shell body, reduce the degree that the user head received harm, and when external force action was too big, cap shell body 1 takes place the breakage, fragment contact buffer layer 5 and non-direct contact user head.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the spirit of the invention.

Although the terms of the cap housing body 1, the airing holes 2, the second-order visor set 3, the visor 4, the cushioning layer 5, the fixing net 6, the webbing 7, the fixing strips 8, the center cleat 9, the connecting band 10, the reinforcing plate 11, etc. are used more frequently herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention and should not be interpreted as imposing any additional limitations that are contrary to the spirit of the present invention.
