Description

Technical Field

[0001] The utility model relates to the technical field of shoe components, in particular to an easy-to-push-on heel lining with an extended edge. Background Art

[0002] Backing is a reinforcing material used in the heel of a shoe. Its primary function is to maintain the shoe's shape and prevent deformation. It's typically placed between the lining and the upper at the heel, providing support and stability. This ensures the toe and heel remain straight and stable, making the shoe's structure more rigid and less prone to deformation, thereby ensuring the shoe maintains its flawless appearance and comfortable feel.

[0003] Existing heel back linings are usually directly glued between the inner lining and the upper. After the shoes are worn for a long time or washed, they are very easy to fall off, thereby losing support for the heel. This not only causes the heel to collapse, affecting the overall appearance of the shoe, but also greatly reduces the comfort of wearing the shoe. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an easy-to-push-on heel lining with an extended edge.

[0005] The purpose of the utility model can be achieved through the following technical solution: a back lining for an easy-to-push heel with an extended edge, comprising a TPU sheet and a lining, wherein the TPU sheet and the lining are welded together and then integrally formed into a back lining body through a hot pressing mold, wherein the back lining body comprises a wrapping portion, the bottom of the wrapping portion is provided with an extended edge, the top of the wrapping portion is provided with a guide portion, and the guide portion is a backward-folded arc structure.

[0006] Preferably, a reinforcing cloth is bonded to the inner side of the rear lining body.

[0007] Preferably, a positioning notch is provided in the middle of the extension.

[0008] Preferably, the side edge of the rear lining body is provided with an arc segment.

[0009] Preferably, the lining sheet is a nonwoven fabric.

[0010] The beneficial effect of the utility model is that the utility model forms an extension edge at the bottom edge of the wrapping part, so that the sole can be fixed to the extension edge by gluing, sewing, etc., thereby improving the firmness of the installation and preventing the rear lining body from falling off.

[0017] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0018] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] See Figures 1 to 4As shown, the structure of the utility model is: a back lining for an easy-to-step heel with an extended edge, comprising a TPU sheet 107 and a lining 108. The TPU sheet 107 and the lining 108 are welded together and then integrally formed into a back lining body 1 through a hot pressing mold. The back lining body 1 comprises a wrapping portion 101, a bottom of the wrapping portion 101 is provided with an extended edge 102, and a guide portion 103 is provided above the wrapping portion 101. The guide portion 103 is a backward-turned arc-shaped structure. Specifically, the cut TPU sheet 107 and the lining 108 are placed in the mold, and the mold is heated to weld the TPU sheet 107 and the lining 108 together to form the back lining body 1. The contour is formed by forming a wrapping portion 101 on the back lining main body 1, which fits the shape of the heel and provides sufficient support and protection for the heel, avoiding sprains and the like caused by uneven road surface during walking, and at the same time can clamp the heel to prevent the shoe from falling off. By forming a backward-turned arc-shaped guide portion 103 on the back lining main body 1, the heel can be easily put into the shoe along the guide portion 103 when wearing the shoe, effectively improving the convenience of wearing the shoe. An extension 102 is formed on the bottom edge of the wrapping portion 101, so that the sole can be fixed to the extension 102 by gluing, sewing, etc., thereby improving the firmness of the installation and preventing the back lining main body 1 from falling off.

[0021] like Figure 1 As shown, a reinforcing cloth 104 is bonded to the inner side of the back lining body 1. Specifically, the reinforcing cloth 104 is used to improve the strength and support of the back lining body 1, and also prevent TPU from penetrating into the inner lining of the shoe when the back lining body 1 is installed.

[0022] like Figure 2 As shown, a positioning notch 105 is provided in the middle of the extension 102. Specifically, the positioning notch 105 is used for positioning during installation.

[0023] like Figure 1 As shown, the side of the back lining body 1 is provided with an arc segment 106. Specifically, the arc segment 106 is used to prevent the back lining body 1 from rubbing against the ankle during walking.

[0024] Furthermore, the lining sheet 108 is a non-woven fabric. Specifically, the non-woven fabric has good flexibility, is easy to shape, and is also conducive to bonding with the melted TPU sheet 107.

[0025] During specific use, the cut TPU sheet 107 and lining sheet 108 are placed in the mold, and the mold is heated to weld the TPU sheet 107 and lining sheet 108 into one, and the outline of the back lining body 1 is formed. The wrapping portion 101 is formed on the back lining body 1 to fit the shape of the heel, providing sufficient support and protection for the heel, avoiding sprains and the like caused by uneven road surfaces during walking, and at the same time, it can clamp the heel to prevent the shoe from falling off. The backward-turned arc-shaped guide portion 103 is formed on the back lining body 1, so that the heel can be easily put into the shoe along the guide portion 103 when wearing the shoe, effectively improving the convenience of wearing the shoe, and the extension 102 is formed at the bottom edge of the wrapping portion 101, so that the sole can be fixed to the extension 102 by gluing, sewing, etc., thereby improving the firmness of the installation and preventing the back lining body 1 from falling off.

[0026] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
