Description

Technical Field

[0001] This utility model relates to the field of shoe support technology, and in particular to a wear-resistant and indentation-resistant cardboard lining. Background Technology

[0002] Shoe trees, also known as shoe linings, are widely used in various types of shoes, such as foam shoe trees and cardboard shoe trees. Cardboard shoe trees are usually made of cardboard or corrugated paper and are mainly used for shoe packaging, transportation, or storage to prevent shoes from deforming, collapsing, or wrinkling. When using existing cardboard shoe trees, they are inserted into the shoe and come into contact with the insole. Because the bottom edges of the cardboard shoe tree are sharp after die-cutting and the contact area is small, the pressure of the cardboard shoe tree on the insole is relatively large. Therefore, after the shoes are stored for a period of time, the part of the insole that is in continuous contact with the bottom edges of the cardboard shoe tree will be crushed by the cardboard shoe tree and form deep indentations. Correspondingly, the large pressure of the bottom edge of the cardboard shoe tree on the insole increases the friction between the two. Moreover, the bottom edge of the cardboard shoe tree is the cross-section of the paper layer. After repeated friction between the bottom edge of the cardboard shoe tree and the insole, it is easy to wear out and shed lint onto the insole, contaminating the insole and requiring the replacement of the insole. Therefore, it is necessary to design a new cardboard shoe tree structure to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a support part of a wear-resistant and indentation-resistant cardboard liner with a support member. After the support is folded and formed, the support member can contact the insole and support the cardboard body. This increases the contact area between the cardboard shoe support and the insole, thereby reducing the pressure of the cardboard shoe support on the insole to prevent the insole from being crushed during storage. In addition, the friction between the support member and the insole is reduced to prevent the cardboard shoe support from shedding debris and contaminating the insole after repeated friction.

[0004] A wear-resistant and indentation-resistant cardboard liner includes a cardboard body, the cardboard body including a support portion and support members, and a plurality of the support members are connected to the edge of the support portion. The support portion is converging and forming an arched structure in the hollow front half of the shoe, and the plurality of support members contact the insole to support the cardboard body.

[0005] Preferably, the rear side of the support is a horizontal structure, and the left and right sides of the support are arc-shaped structures with an arch shape.

[0006] Preferably, the support member is a flip-up plate protruding from the side of the support portion, and the support member can be flipped inward to support the cardboard body.

[0007] Preferably, the support portion has multiple through holes at the joint of the support member.

[0008] Preferably, the support member is a molded plate that protrudes from the side of the support portion, and the support member can be recessed inward to form a column supporting the cardboard body.

[0009] The beneficial effects of this utility model are: the wear-resistant and pressure-resistant cardboard liner is provided with a support part and a support member through mutual cooperation, so that the support part is provided with a support member. After the support is folded and shaped, the support member can contact the insole and support the cardboard body, which can increase the contact area between the cardboard shoe tree and the insole, thereby reducing the pressure of the cardboard shoe tree on the insole to prevent the insole from being crushed during storage. In addition, the friction between the support member and the insole is reduced to prevent the cardboard shoe tree from shedding debris and contaminating the insole after repeated friction.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0016] like Figures 1 to 4 As shown, a wear-resistant and indentation-resistant cardboard liner includes a cardboard body, which includes a support portion 1 and support members 2. A plurality of support members 2 are connected to the edge of the support portion 1. The support portion 1 is tapered and forms an arched structure in the hollow front half of the shoe, and the plurality of support members 2 are in contact with the insole to support the cardboard body.

[0017] The working principle of the wear-resistant and indentation-resistant cardboard liner of this utility model is achieved through the cooperation of the support part 1 and the support member 2, such as... Figures 1 to 4 As shown, the support part 1 is provided with a support member 2. The cardboard body is formed into a shoe support through a hot pressing process. After the support is formed, the support member 2 can contact the insole and support the cardboard body. This can increase the contact area between the cardboard shoe support and the insole, thereby reducing the pressure of the cardboard shoe support on the insole and the friction between the two. Compared with traditional shoe linings, this wear-resistant and indentation-resistant cardboard lining can prevent the insole from being crushed by the cardboard shoe support during storage and prevent the cardboard shoe support from shedding debris and contaminating the insole after repeated friction.

[0018] Specifically, the rear side of the support part 1 is a horizontal structure, and the left and right sides of the support part 1 are arc-shaped structures with an arched shape. In the first embodiment of the support member 2, the support member 2 is a flip-out plate protruding from the side of the support part 1, and the support member 2 can be flipped inward to support the cardboard body, such as... Figures 1 to 2 As shown, after the support part 1 is folded into shape, the support member 2 can be folded inward and support the cardboard body, so that the support member 2 replaces the paper edge of the cardboard body and contacts the insole. This increases the contact area between the cardboard shoe support and the insole, thereby reducing the pressure of the cardboard shoe support on the insole and preventing the insole from being crushed by the cardboard shoe support during storage. Compared with the paper edge of the cardboard body, the surface of the support member 2 is not easily worn. The contact between the support member 2 and the insole can also reduce the friction between the cardboard body and the insole, preventing the cardboard shoe support from shedding debris and contaminating the insole after repeated friction. Furthermore, the support part 1 is provided with multiple through holes 3 at the joint of the support member 2. The through holes 3 can be formed on the cardboard body by punching. The through holes 3 facilitate the support member 2 to be folded inward and support the cardboard body.

[0019] In the second embodiment of the support member 2, the support member 2 is a molded plate sheet protruding from the side of the support portion 1, and the support member 2 can be recessed inward to form a column 4 supporting the cardboard body, such as... Figures 3 to 4 As shown, after the support part 1 is formed, the support member 2 can be recessed inward to form a column 4 that supports the cardboard body. The support member 2 forms a concave hole on the surface of the formed support part, which can increase the contact area between the cardboard shoe tree and the insole, thereby reducing the pressure of the cardboard shoe tree on the insole, so as to prevent the insole from being crushed by the cardboard shoe tree during storage. Moreover, compared with the paper edge of the cardboard body, the surface of the column 4 is not easily worn. The contact between the support member 2 and the insole can also reduce the friction between the cardboard body and the insole, and prevent the cardboard shoe tree from shedding debris and contaminating the insole after repeated friction.

[0020] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
