Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a shoe support lining structure that facilitates putting on and taking off shoes. Background Technology

[0002] As a core component for maintaining shoe stability, improving foot support, and enhancing wearing comfort, the structure of the shoe support lining directly affects the product's performance.

[0003] For example, Chinese patent CN218219337U discloses a shoe heel structure, including a shoe with an opening. The shoe has a heel body distributed along the edge of the opening. The heel body, extending outward from the opening, includes: an inner lining, a protective sheet, a support sheet, and an outer layer. The inner lining, protective sheet, support sheet, and outer layer are sequentially bonded and fixed to each other. The protective sheet and the support sheet are both curved surfaces designed to cover the heel. The protective sheet has a first end face and a second end face. The first end face and the second end face are respectively bonded and fixed to the inner lining and the support sheet. A soft protrusion is fixedly provided on the first end face, and the soft protrusion is distributed along the edge of the opening. This reduces the likelihood of heel rubbing against the foot.

[0004] The above solution has the advantages mentioned above, but its disadvantages are: the lining material is cloth, which has insufficient support, making it more difficult to put on shoes; the support structure only has a single external or internal support, which makes it difficult to achieve all-round balanced support; and the connection stability between the support components and other structures is not good, which makes it easy to misalign or shift during molding and use, affecting the durability of the support effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a shoe support lining structure that facilitates putting on and taking off shoes, thus solving the problem of difficulty in putting on and taking off shoes.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a shoe support lining structure that facilitates wearing and removal, comprising: an inner lining structure, the inner lining structure further comprising a support lining, an inner support strip fixedly connected to the outer wall inside the support lining, an outer support strip fixedly connected to the outer wall outside the support lining, a fixing protrusion fixedly connected to the outer wall below the support lining, a groove formed on the inner wall of the fixing protrusion, and a splitting hole formed through the outer wall inside the groove, the groove and the splitting hole facilitating the separation of the fixing protrusion from the support lining. The bidirectional support of the inner support strip and the support lining improves the support balance of the lining structure, avoiding uneven stress caused by single support; the outer support strip further enhances the stability of the overall structure and extends the service life of the lining; the combination of the groove and the splitting hole simplifies the process of separating the fixing protrusion from the support lining, reducing maintenance difficulty and cost. When the fixing protrusion is damaged, only that component needs to be replaced, without replacing the entire lining structure, making it more energy-efficient and environmentally friendly.

[0009] Preferably, the inner wall of the support liner has ventilation holes. The support liner is made of elastic polyethylene. The ventilation holes allow air to circulate and exchange between the inside of the shoe and the outside, effectively dissipating heat and moisture generated by the feet, improving the stuffy and humid environment inside the shoe, enhancing wearing comfort, and reducing odor. The elastic properties of polyethylene give the support liner sufficient support rigidity while flexibly adapting to foot movements, reducing friction resistance when putting on and taking off the shoes, and reducing the pressure caused by prolonged wear, thus improving the overall wearing experience. In addition, the material has good wear resistance, extending the service life of the liner.

[0010] Preferably, the inner wall of the upper part of the support liner curves outward, and the outer wall of the lower part of the support liner curves inward. The outward curve of the upper part of the support liner expands the entry and exit passage of the shoe opening, reduces the contact resistance between the foot and the support liner when putting on and taking off the shoe, and makes the process of putting on and taking off the shoe smoother and less strenuous. The inward curve of the lower outer wall enhances the fit between the support liner and the foot, ensuring that the support force can be applied to the parts of the foot that need support, improving support stability, and reducing the relative sliding between the liner and the foot when walking or exercising, reducing the risk of friction damage, and further improving the comfort and safety of wearing the shoe.

[0011] Preferably, the inner wall of the fixing protrusion is provided with a positioning hole, and two fixing protrusions are provided. The fixing protrusions play a positioning role when supporting the lining for molding, preventing the supporting lining from being misaligned. The two symmetrically distributed fixing protrusions cooperate with the mold through the positioning hole, which solves the technical problem of easy misalignment of the lining structure during the molding process, improves the size consistency and assembly of the product, and ensures that each lining product can fit the corresponding shoe type. The positioning hole not only simplifies the positioning process during molding and improves production efficiency, but also provides a positioning benchmark for the subsequent assembly of the lining and the shoe body, reduces assembly errors, and improves the overall structural stability and wearability of the shoe body.

[0012] (III) Beneficial Effects

[0013] This invention provides a shoe support lining structure that facilitates putting on and taking off shoes. It has the following beneficial effects:

[0014] (I) This easy-to-wear shoe support lining structure, through the upward and downward concave shape of the support lining, expands the space for entering and exiting the shoe opening and conforms to the contour of the foot. Combined with the elastic deformation characteristics of polyethylene material, it significantly reduces the contact resistance and friction resistance when putting on and taking off the foot, achieving a smooth and effortless wearing experience. At the same time, the three-dimensional support system composed of inner and outer support strips can provide all-round balanced support for the foot, avoiding the problem of concentrated force or insufficient support. The outer support strip further strengthens the rigidity of the frame, inhibits structural deformation, and ensures long-term stable support performance, taking into account both convenient wearing and taking off and reliable support.

[0015] (II) This easy-to-wear shoe support lining structure creates an air circulation channel between the inside and outside of the shoe through the ventilation holes on the support lining. It can quickly dissipate heat and moisture from the feet, improve the stuffy environment inside the shoe, reduce odor, and reduce the pressure on the feet by combining the elasticity and adaptability of polyethylene material. It also enhances the comfort of wearing the shoe for a long time. In addition, the positioning holes of the fixing protrusions ensure that the product size is consistent and the shoe shape is well adapted after molding. The coordinated design of the groove and split hole can separate the fixing protrusions and the support lining without complicated tools, which is convenient for subsequent maintenance and replacement, reduces the cost of use, and balances production precision and maintenance convenience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 Figure shows a technical solution for a shoe support lining structure that is easy to put on and take off: including: lining structure 1, lining structure 1 further including support lining 11, inner support strip 15 is fixedly connected to the outer wall inside the support lining 11, outer support strip 13 is fixedly connected to the outer wall outside the support lining 11, fixing protrusion 14 is fixedly connected to the outer wall below the support lining 11, groove 18 is provided on the inner wall of fixing protrusion 14, split hole 19 is provided through the outer wall inside the groove 18, the groove 18 and split hole 19 can facilitate the separation of fixing protrusion 14 from support lining 11.

[0023] The inner wall of the support liner 11 is provided with a through-hole 12, and the support liner 11 is made of polyethylene, which is elastic.

[0024] The inner wall above the support liner 11 curves outward, while the outer wall below the support liner 11 is concave inward.

[0025] The inner wall of the fixing protrusion 14 is provided with a positioning hole 17. There are two fixing protrusions 14. The fixing protrusions 14 play a positioning role when the inner liner 11 is molded, so as to prevent the inner liner 11 from being misaligned.

[0026] In use, the inner lining structure takes the inner lining 11 as the main frame. The inner support strip 15 fixed on the inside and the outer support strip 13 fixed on the outside form a three-dimensional support system. The inner support strip 15 conforms to the inner contour of the foot, and the inner lining 11 bears the overall support force. The two work together to achieve all-round balanced support for the foot, avoiding the problem of force concentration or insufficient support caused by a single support structure. The outer support strip 13 is distributed along the extension direction of the inner lining 11, further strengthening the rigidity of the frame, suppressing structural deformation during use, extending the overall service life of the inner lining, and ensuring long-term stable support performance.

[0027] The support lining 11 adopts an upward and downward concave shape. The structure of the upper inner wall that curves outward expands the opening space of the shoe opening, reduces the restriction of the passage when the foot enters and exits, and reduces contact resistance. The structure of the lower outer wall that curves inward conforms to the lower contour of the foot, so that the lining forms a smooth and conforming trajectory with the foot during the process of putting on and taking off, avoiding hard friction and obstruction. At the same time, the support lining 11 is made of elastic polyethylene material, which can deform appropriately with the foot's putting on and taking off movements, further reducing friction resistance when entering and exiting, making the process of putting on and taking off the shoes smoother and less strenuous.

[0028] The ventilation holes 12 running through the inner wall of the support lining 11 create an air circulation channel between the inside of the shoe and the outside. When wearing the shoe, the heat and moisture generated by the feet can be quickly dissipated to the outside through the ventilation holes 12, while fresh air from the outside enters the shoe to form a circulation, effectively improving the stuffy and humid environment inside the shoe, reducing odor, and improving the comfort of wearing the shoe for a long time. The elastic properties of the polyethylene material can also adapt to the movement trajectory of the foot, reducing the pressure of the support structure on the foot and further optimizing the wearing experience.

[0029] The positioning holes 17 on the fixed protrusions 14 play a key role in the molding stage. The two symmetrically distributed fixed protrusions 14 cooperate with the mold positioning components through the positioning holes 17 to limit the displacement of the support liner 11 during the injection molding process, avoid misalignment or displacement during molding, and ensure the dimensional consistency and shoe fit of each liner product. Before the support liner 11 is sewn into the shoe, the groove 18 and the split hole 19 can provide a force-bearing point and disperse the split stress. The fixed protrusions 14 and the support liner 11 can be separated without complicated tools.
