Description

Shock-absorbing insole

Technical Field

The utility model relates to a shoe-pad technical field, in particular to shock attenuation shoe-pad.

Background

The traditional insole is generally supported by foaming materials such as EVA (ethylene vinyl acetate) or PU (polyurethane), the foaming materials have certain elasticity, but the elasticity of the foaming materials is weakened greatly under the long-time use and compression of the main stress part (such as the heel part) of the insole, and the local elasticity failure of the insole is easy to occur.

In order to solve the above problems, chinese patent with the publication number CN 207306218U discloses a shock-absorbing insole, which comprises an insole body, wherein the front, middle and rear parts of the insole body are respectively a sole part, a waist nest part and a heel part, and the shock-absorbing insole is characterized in that: the lower part of the sole part and the lower part of the heel part are respectively connected with a first silica gel pad and a second silica gel pad which are attached to the insole body. The current shock attenuation shoe-pad adopts silica gel to provide the shock attenuation at main atress part and supports, and the silica gel texture is soft, and the shock attenuation is effectual, but also because its texture is soft simultaneously, in order to guarantee to bear sufficient impact force, the silica gel thickness that needs is thicker, therefore the global design thickness of shoe-pad is thicker, because the shoes inner space is limited, is difficult to put into thick shoe-pad in the shoes, and too thick shoe-pad will influence the travelling comfort of dress.

Detailed Description

The present invention will be further described with reference to the following detailed description.

Referring to fig. 1 to 3, a shock-absorbing insole comprises an insole body 1 and a shock-absorbing block 2.

The cushion body 1 is made of soft foaming materials, the upper surface of the cushion body 1 is covered with a net cloth layer 11, a mounting groove 12 is formed in the heel of the bottom of the cushion body 1, the damping block 2 is adhered in the mounting groove 12 in a hot melting mode, and the bottom of the damping block 2 in the mounting groove 12 is in gentle transition with the cushion body 1.

The damping block 2 comprises a silica gel layer 21 and a plurality of elastic particles 22, the elastic particles 22 are embedded in the silica gel layer 21, gaps among the elastic particles 22 are filled with silica gel of the silica gel layer 21, and the damping block 2 is bonded in the mounting groove 12 through hot melting. The elastic particles 22 are made of ETPU (Ethyl tetra methyl polyurethane) materials (high resilience lightweight thermoplastic polyurethane elastomers), the elastic particles 22 are spherical or approximately spherical colored particles, the particle size of the elastic particles 22 is 0.5mm-2mm, the silica gel layer 21 is made of transparent silica gel, the colored elastic particles can be observed through the silica gel layer 21, the attractiveness is good, and the hardness value of the elastic particles 22 is greater than that of the silica gel layer 21.

During the preparation of snubber block 2, place into the mould of preparation snubber block earlier with elastic particle 22 in, then pour into fused silica gel into, fused silica gel has better mobility, and among the flow process, fused silica gel will fill the gap between the elastic particle and wrap up elastic particle 22 in it simultaneously, and silica gel cooling solidification forms the silica gel layer 21 of having wrapped up elastic particle 22 after, accomplishes the preparation of snubber block 2.

The damping block 2 is placed in a mold for manufacturing the cushion body in advance, the installation groove 12 is naturally formed in the injection molding process of the cushion body 1 material, the damping block 2 and the cushion body 1 material are bonded in a hot melting mode, and the bottom surface of the damping block 2 and the cushion body 1 naturally form gentle transition.
