Description

Waterproof liner

Technical Field

The utility model relates to the field of waterproof shoes, in particular to a waterproof liner.

Background

In order to enhance the waterproof capability, the existing outdoor shoes are often provided with a waterproof liner made of synthetic textile fabrics in the shoes, and the existing waterproof liner is mostly formed by splicing and sewing double or multiple waterproof liner raw materials, and then the waterproof strips are attached to the stitching lines in an attaching mode on the outer side, so that the stitching lines are sealed and waterproof, but the design is sealed and the waterproof liner is relatively general due to the fact that the waterproof liner is relied on, and the production process is relatively complex.

Disclosure of Invention

The utility model mainly aims to provide a waterproof liner which is connected in a double-layer hot-pressing mode, can reduce production complexity and improves waterproof performance.

The utility model provides a waterproof liner, which comprises a first outer waterproof layer, a second outer waterproof layer, a first inner waterproof layer and a second inner waterproof layer, wherein the first outer waterproof layer is arranged on the first inner waterproof layer in a hot-press connection mode, the outer diameter of the first inner waterproof layer is smaller than that of the first outer waterproof layer, so that an inner connecting groove is formed in the side face of the first inner waterproof layer, the second outer waterproof layer is arranged on the second inner waterproof layer in a hot-press connection mode, the outer diameter of the second inner waterproof layer is larger than that of the second outer waterproof layer, so that an inner connecting edge is formed in the side face of the second inner waterproof layer, and the first outer waterproof layer is connected with the second inner waterproof layer in a hot-press connection mode through the cooperation of the inner connecting edge and the inner connecting groove, so that the waterproof liner is formed through connection.

Preferably, an opening is formed in the top of the waterproof liner, the outer diameters of the first inner waterproof layer and the first outer waterproof layer at the opening are identical, and the outer diameters of the second inner waterproof layer and the second outer waterproof layer are identical.

Preferably, the waterproof strip is attached to the outer side of the connection part of the first outer waterproof layer and the second outer waterproof layer, so that the waterproof performance of the waterproof liner is enhanced through the waterproof strip.

The waterproof liner has the beneficial effects that:

1. through the hot pressing connection of the first outer waterproof layer and the second inner waterproof layer, a Z-shaped connection part is formed at the connection part, and therefore the waterproof performance of the waterproof liner is improved.

2. The waterproof strips are arranged on the outer sides of the connecting parts of the first outer waterproof layer and the second outer waterproof layer in a fitting mode, and therefore the waterproof performance of the waterproof liner is enhanced through the waterproof strips.

reference numerals in the drawings: 1. the waterproof layer comprises a first outer waterproof layer, 2, a second outer waterproof layer, 3, a first inner waterproof layer, 4, a second inner waterproof layer, 5 and waterproof strips.

The achievement of the objects, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings, in conjunction with the embodiments.

Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 3, an embodiment of the waterproof liner of the present utility model is provided:

a waterproof liner comprises a first outer waterproof layer 1, a second outer waterproof layer 2, a first inner waterproof layer 3, a second inner waterproof layer 4 and waterproof strips 5.

The first outer waterproof layer 1 is arranged on the first inner waterproof layer 3 in a hot-press connection mode, the outer diameters of the left side, the right side and the lower side of the first inner waterproof layer 3 are smaller than those of the first outer waterproof layer 1, and the outer diameters of the upper side and the first outer waterproof layer 1 are consistent, so that inner connecting grooves are formed in the left side, the right side and the lower side of the first inner waterproof layer 3.

The second outer waterproof layer 2 is arranged on the second inner waterproof layer 4 in a hot-press connection mode, the outer diameters of the left side, the right side and the lower side of the second inner waterproof layer 4 are larger than those of the second outer waterproof layer 2, and the outer diameters of the upper side and the second outer waterproof layer 2 are identical, so that inner connecting edges are formed on the left side, the right side and the lower side of the second inner waterproof layer 4.

The first outer waterproof layer 1 is connected with the second inner waterproof layer 4 by hot-pressing the inner connecting edges to the inner connecting grooves, so that the waterproof inner container is formed by connection. Through the hot pressing connection of the first outer waterproof layer 1 and the second inner waterproof layer 4, a Z-shaped connection part is formed at the connection part, and therefore the waterproof performance of the waterproof liner is improved. And an opening is formed at the top of the waterproof liner. The waterproof strip 5 is arranged on the outer side of the joint of the first outer waterproof layer 1 and the second outer waterproof layer 2 in a fitting mode, and the waterproof performance of the waterproof liner is enhanced through the waterproof strip 5.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the present utility model and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present utility model.
