High-elastic vibration reduction box structure, manufacturing method and sole with embedded high-elastic vibration reduction box

Abstract

A high-elastic vibration reduction box structure comprises a high-elastic vibration reduction box body and a high-elastic vibration reduction box. A cavity of the box body is filled with polyurethane gelatum uniformly mixed with polyurethane particles, and a box cover is hermetically and fixedly connected with an end opening of the box body. The box body and the box cover are made of polyester polyurethane elastomer, the polyurethane particles are made of polyether foam polyurethane, and the polyurethane gelatum is made of polyether thermoplastic polyurethane elastomer. The sole with the embedded high-elastic vibration reduction box is characterized in that the high-elastic vibration reduction box is embedded into a heel, a rear foot sole and / or the inside of a forefoot sole of an insole, or the inside of the whole insole, and the contour of the high-elastic vibration reduction box is held in that of the insole. The polyurethane gelatum has a high vibration reduction performance, vibration reduction effects can be further improved as the polyurethane particles are mixed in the polyurethane gelatum, the sole with the embedded high-elastic vibration reduction box has an excellent vibration reduction performance by the aid of the vibration reduction performance of the high-elastic vibration reduction box body and the box cover made of the polyurethane elastomer, a human body is prevented from being damaged, and the effects are remarkable.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a shoe sole embedded with a high elastic damping box. Background technique [0002] Shoes are tools that protect the feet and maintain sufficient friction between the feet and the ground when humans walk or work. The sole is the most important part of the shoe, which bears all the loads of the human body and the weight. The usual sole includes The outsole in direct contact with the ground and the midsole on top of the outsole. In order to protect the foot perfectly and minimize the maximum local pressure on the foot when the wearer of the shoe walks or works, the sole needs to minimize the extreme value of the impact load on the foot and disperse the impact load as much as possible. The entire surface of the soles of the feet is used to prevent the human body from being damaged. For this purpose, more and more air cushions are installed inside the soles in order to reduce the maximum pressure and ...

In order to protect the foot perfectly and minimize the maximum local pressure on the foot when the wearer of the shoe walks or works, the sole needs to minimize the extreme value of the impact load on the foot and disperse the impact load as much as possible. The entire surface of the soles of the feet is used to prevent the human body from being damaged. For this purpose, more and more air cushions are installed inside the soles in order to reduce the maximum pressure and impact on the soles of the feet. However, the results of use have proved that the flexible airtight containers filled with air cushions When the gas is stressed, it will flow in the direction of low pressure, so that the shape of the air cushion will be deformed and the structure will be unstable, so that the wearer's feet will lose the necessary support, greatly increasing the chance of foot injury, and at the same time limited by the air cushion material , the compression deformation life of the air cushion is far less than the bending life of the sole, thus greatly shortening the service life of the air cushion sole
