Detailed Description

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

As shown in fig. 2 and 3, a plurality of receiving grooves 11 towards the center of the sphere on which the cap shell 1 is located are formed on the outer side wall of the cap shell 1, and supporting blocks 12 are clamped in the receiving grooves 11. Fixedly connected with accomodates bead 112 on the lateral wall of supporting shoe 12, and the position department that the cap shell 1 is close to accomodating groove 11 has seted up accomodates recess 111, and when supporting shoe 12 inserted completely and accomodate groove 11, accomodate bead 112 and can joint in accomodating recess 111. Buffer grooves 121 which are arranged towards the center of the sphere of the spherical surface where the cap shell 1 is located are formed in the middle of the supporting block 12, and buffer blocks 122 made of metal materials such as steel are connected in the buffer grooves 121 in a sliding mode. The equal fixedly connected with buffer spring 123 in position department that supporting shoe 12 is close to buffer slot 121 both ends, the equal fixed connection in buffer block 122 of one end that buffer spring 123 kept away from supporting shoe 12, when buffer spring 123 all was in quiescent condition, buffer block 122 was located buffer slot 121 middle part. When wearing, take earlier with the supporting shoe 12 joint of suitable quantity in accomodating groove 11 to wear cap shell 1, when receiving the impact, buffer block 122 can make a round trip to slide along dashpot 121 under the pulling force that inertia and spring deformation brought, thereby weaken offset some impact force, reduce the damage of assaulting to the wearer.

As shown in fig. 2 and 3, a buffer layer 13 made of elastic material such as rubber is fixedly connected to the inner side wall of the cap shell 1, and the buffer layer 13 is attached to the inner side wall of the cap shell 1. The inner side of the cap shell 1 is fixedly connected with a support frame 14 which is hemispherical, and a support gap 141 is formed between the spherical surface where the support frame 14 is located and the spherical surface where the cap shell 1 is located. One side of the support frame 14 close to the hat shell 1 is fixedly connected with a plurality of support springs 142, one ends of the support springs 142 far away from the support frame 14 are fixedly connected to the inner side wall of the hat shell 1, and the support springs 142 apply force to the hat shell 1 to slide in the direction far away from the support frame 14. When wearing, with the actual contact of wearer be support frame 14, when the external world has the impact, because support gap 141, cap shell 1 can slide to support frame 14, at this moment, supporting spring 142 can offset the impact force on the one hand, and on the other hand buffer layer 13 can disperse sharp-pointed impact force when cap shell 1 butt wearer to reduce the damage that the wearer received.

As shown in fig. 2 and 3, ear protection shells 15 are fixedly connected to both sides of the cap shell 1. Ear protection cushion blocks 151 made of sponge and other soft materials are connected to the inner side walls of the ear protection shells 15 in a sliding mode, and the two ear protection cushion blocks 151 can slide towards opposite directions. The adjusting springs 152 are fixedly connected to the ends, close to the ear protection shells 15, of the ear protection cushion blocks 151, the ends, far away from the ear protection cushion blocks 151, of the adjusting springs 152 are fixedly connected to the corresponding ear protection shells 15, and the adjusting springs 152 apply force to the ear protection cushion blocks 151, wherein the force is sliding in the direction far away from the ear protection shells 15. When wearing, the person of wearing accessible soft ear protection cushion 151 protects the ear, and ear protection cushion 151 also can effectively reduce ambient noise simultaneously, protects person of wearing's hearing.

In this way, the wearer can select a proper number of the supporting blocks 12 to be inserted into the receiving grooves 11 at proper positions, balance the weight and the necessary impact resistance, and then can normally wear the cap shell 1 for work.

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.
