Detailed Description

Example (b): a breathable safety helmet comprises a hemispherical helmet shell 1. The wearer can wear the mask directly when in use.

As shown in fig. 1 and 2, a plurality of ventilation grooves 11 towards the center of the sphere where the cap shell 1 is located are formed in the cap shell 1, the ventilation grooves 11 are all arranged through the cap shell 1, ventilation nets 111 covering the ventilation grooves 11 are fixedly connected to positions, close to the ventilation grooves 11, of the inner side wall of the cap shell 1, and the ventilation nets 111 are all made of rigid materials such as steel. When the wearer wears the helmet, the ventilation net 111 can effectively improve the ventilation of the helmet shell 1, and meanwhile, the strength of steel can be insufficient for the structural strength of the helmet shell 1.

As shown in fig. 1 and fig. 2, the positions of the outer side wall of the cap shell 1 near the ventilation groove 11 are all inserted with ventilation end covers 112 capable of covering the ventilation groove 11. The inner side wall of the ventilation end cover 112 close to is fixedly connected with a limiting block 113 made of elastic material, and the limiting block 113 can cover the ventilation groove 11. The stopper 113 is close to a plurality of buffer springs of fixedly connected with on the face of ventilative net 111, when stopper 113 pegs graft in ventilative groove 11, buffer spring can with ventilative net 111 butt. When the wearer does not emphasize the air permeability, the air-permeable end cover 112 can be inserted into the air-permeable groove 11 through the clamping connection of the limiting block 113 and the air-permeable groove 11, and at the moment, the impact force can be relieved by the air-permeable spring 114 through the reverse acting force to the impact force source.

As shown in fig. 1 and 2, a buffer layer 12 made of an elastic material is fixedly connected to the inner side wall of the cap shell 1, the buffer layer 12 is attached to the inner side wall of the cap shell 1, and the buffer layer 12 is in a mesh shape. The inner side of the cap shell 1 is fixedly connected with a support frame 13 which is hemispherical, and a support gap 132 is formed between the spherical surface where the support frame 13 is located and the spherical surface where the cap shell 1 is located. One side of the support frame 13 close to the cap shell 1 is fixedly connected with a plurality of support springs 131, one ends of the support springs 131 far away from the support frame 13 are fixedly connected to the inner side wall of the cap shell 1, and the support springs 131 apply force to the cap shell 1 to slide in the direction far away from the support frame 13. When wearing, with the actual contact of wearer be support frame 13, when the external world has the impact, because support space 132, cap shell 1 can slide to support frame 13, at this moment, supporting spring 131 can offset the impact force on the one hand, and on the other hand buffer layer 12 can disperse sharp-pointed impact force when cap shell 1 butt wearer to reduce the damage that the wearer received.

As shown in fig. 1 and 2, ear protection shells 14 are fixedly connected to both sides of the cap shell 1. The ear protection shell 14 has a plurality of through holes 141. The ear protection shell 14 can effectively protect the ear position of the wearer, and the arrangement of the through hole 141 can keep the ear position of the wearer to be good in ventilation.

In a using mode, an operator can take down or buckle the breathable end cover 112 according to the needs of the operator, so that the breathable effect of the safety helmet is kept, and the effect of keeping the breathable effect while protecting the head is achieved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
