Problems solved by technology

The shortcoming of this insole is that structure is more complicated, and manufacture trouble, and manufacturing material is many, and cost is higher; Also, when this insole is placed on the sole surface when people walk on the insole, it is easy to make the insole slide due to the transformation of the point of focus on the sole of the foot. , causing walking is very inconvenient and uncomfortable, so its structure needs to be improved

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] As shown in Fig. 1 to Fig. 6, the insole of the present embodiment comprises the face cloth 1 of sole shape, is provided with the polyurethane auxiliary cushion layer 3 of the pure polyurethane face that surface does not have film on the bottom surface of face cloth 11, and in On the lower surface of the auxiliary cushion layer 3, a polyurethane cushion layer 2 with a pure polyurethane surface without a film protrudes from the position of the force-bearing part of the heel and the sole of the foot. The surfaces of the auxiliary cushion layer 3 and the soft cushion layer 2 have no film coating, so they have certain viscosity and can be pasted together with the sole. And on the lower surface of the auxiliary cushion layer 3 and positioned at the foot bridge cavity position, the polyurethane foot bridge cushion layer 22 that is integrated ...

Abstract

The invention discloses an insole which comprises a sole-shaped shell fabric (1) and is characterized in that a polyurethane auxiliary bedding layer (3) with a pure polyurethane surface without a film is arranged on the lower bottom surface of the shell fabric (11), and a polyurethane soft bedding layer (2) with the pure polyurethane surface without the film is arranged convexly on the lower surface of the auxiliary bedding layer (3) at the position on which a heel and a sole exert forces. Compared with the prior art, the insole has the advantages that people feel that the insole is soft and comfortable when stepping on the insole, and the insole can stick to the bottom surface of a shoe steadily, thereby solving the problem that the insole slips with the change of the force-exerting points of the sole; besides, the insole has simple structure, convenient production and low cost.

Description

technical field [0001] The invention relates to the technical field of making insoles, in particular to a polyurethane insole. Background technique [0002] An existing Chinese utility model patent with the patent No. CN03256541.0 proposes a structure, which is characterized in that: the insole is at least made of a cloth surface, a preformed high-temperature-resistant coated fluid soft material and a PU foam material. Composition, the cloth surface is preset with perforated holes, the preformed high temperature resistant coated fluid soft object is hung on the preset perforated hole on the cloth surface, and the cloth with preformed high temperature resistant coated fluid soft object is hung. The bottom of the surface is provided with a PU foam material integrally formed with it. The disadvantage of this insole is that the structure is more complicated, the production is troublesome, the production materials are many, and the cost is higher; in addition, when the insole is...
