Description

Technical Field

[0001] This utility model relates to the field of PU women's shoes technology, specifically to a PU women's shoe with good anti-slip performance. Background Technology

[0002] PU women's shoes refer to women's footwear made of polyurethane (PU) material. Polyurethane is a synthetic material with many excellent properties, which makes it widely used in the production of women's shoes. PU women's shoes usually have good waterproof, breathable and wear-resistant properties. In addition, PU material is relatively lightweight, comfortable to wear, and has a certain degree of elasticity, which can provide good support and cushioning.

[0003] Shoes made of this material are stylish and come in a variety of styles, suitable for different occasions. In the market, PU women's shoes are favored by consumers for their high cost performance and durability. The anti-slip performance of PU women's shoes is one of the core features that ensures wearing safety and practical experience, playing a key role in daily wearing scenarios.

[0004] PU women's shoes typically have a certain degree of slip resistance on their soles, but this slip resistance relies solely on fixed ridges formed integrally on the sole surface. These ridges are mostly simple strip or block structures with fixed depth and density, making it impossible to adjust them according to different surface friction requirements. On dry cement, asphalt, and other conventional surfaces, the ridges can provide a certain degree of slip resistance through basic friction. However, on smooth surfaces such as tiles and wet surfaces, the friction coefficient between the ridges and the ground is insufficient, making it easy for "water film lubrication" or a smooth surface to cause a significant increase in the risk of slipping. Therefore, this paper proposes a PU women's shoe with good slip resistance to address the above issues. Utility Model Content

[0005] The purpose of this invention is to provide a PU women's shoe with good anti-slip performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A PU women's shoe with good anti-slip performance includes a shoe body and a sole. The bottom edge of the sole is integrally formed with a reinforced edge. An anti-slip cavity is formed between the inner side of the reinforced edge and the bottom of the sole. A first anti-slip component is provided in the anti-slip cavity. A second anti-slip component is provided in the middle of the sole. The second anti-slip component includes a movable groove opened at the center of the bottom of the sole. An adjustable support plate is provided in the movable groove. The adjustable support plate is adapted to the specifications of the movable groove. Multiple anti-slip suction cups are arranged at equal intervals and fixedly connected to the bottom of the adjustable support plate. The multiple anti-slip suction cups extend into the anti-slip cavity. An adjustment structure is provided inside the movable groove above the adjustable support plate.

[0008] As a further optimization of this utility model, the first anti-slip component includes a plurality of anti-slip protrusions, which extend along the width direction of the sole and are fixedly connected to the bottom of the sole.

[0009] As a further optimization of this utility model, the multiple anti-slip protrusions are arranged at equal intervals, and the bottom of each of the multiple anti-slip protrusions is provided with a groove.

[0010] As a further optimization of this utility model, gaps are formed between adjacent anti-slip ridges and between the anti-slip ridges and the reinforced edge, and the bottom of the anti-slip ridges is flush with the bottom of the reinforced edge.

[0011] As a further optimization of this utility model, the adjustment structure includes a transmission support rod disposed inside the movable groove and located above the adjustment support plate. Multiple cams are arranged at equal intervals on the outer side of the transmission support rod, and the cams are fixedly connected to the transmission support rod.

[0012] As a further optimization of this utility model, a threaded sleeve is fixedly bonded to the middle of one side of the inner cavity of the shoe sole, and an adjusting screw is threadedly connected to the threaded sleeve. The end of the adjusting screw extends into the movable groove. One end of the transmission support rod is rotatably connected to one side of the shoe sole, and the other end of the transmission support rod is fixedly connected to the end of the adjusting screw.

[0013] As a further optimization of this utility model, the adjustment structure further includes multiple sets of telescopic support rods arranged at equal intervals on both sides of the transmission support rod. A return spring is sleeved on the outer side of each telescopic support rod. The upper and lower ends of the telescopic support rod and the return spring are respectively fixedly connected to the top of the inner cavity of the movable groove and the top of the adjustment support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the anti-slip protrusions and grooves of the first anti-slip component provide basic friction, and the gaps help with drainage and dust removal. The second anti-slip component can drive the anti-slip suction cup to rise and fall through mechanical transmission, forming negative pressure adsorption on smooth surfaces to enhance anti-slip. On ordinary surfaces, the suction cup can be retracted to avoid wear, and the reinforced edges ensure structural stability. Overall, it achieves reliable anti-slip on different surfaces, taking into account both practicality and durability. Attached Figure Description

[0026] 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.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figures 1-9 This utility model provides a technical solution:

[0029] A PU women's shoe with good anti-slip performance includes a shoe body 1 and a sole 2. The bottom edge of the sole 2 is integrally formed with a reinforcing edge 3. An anti-slip cavity 4 is formed between the inner side of the reinforcing edge 3 and the bottom of the sole 2. A first anti-slip component 5 is provided in the anti-slip cavity 4. A second anti-slip component 6 is provided in the middle of the sole 2. The second anti-slip component 6 includes a movable groove 61 opened at the center of the bottom of the sole 2. An adjusting support plate 62 is provided in the movable groove 61. The adjusting support plate 62 is adapted to the specifications of the movable groove 61. Multiple anti-slip suction cups 63 are arranged at equal intervals and fixedly connected to the bottom of the adjusting support plate 62. The multiple anti-slip suction cups 63 extend into the anti-slip cavity 4. An adjusting structure 64 is provided inside the movable groove 61 above the adjusting support plate 62.

[0030] It should be noted that the reinforced edge 3, which is integrally molded at the bottom edge of the sole 2, is made of high-hardness PU material (Shore hardness 85A or higher). It not only enhances the overall structural rigidity of the sole 2 by wrapping the edge, preventing deformation of the sole edge during walking, but also forms a closed anti-slip cavity 4 with the inner side of the bottom of the sole 2, providing installation and working space for the first anti-slip component 5. The bottom of the reinforced edge 3 is flush with the bottom of the anti-slip protrusion 51, ensuring that the edge makes uniform contact with the ground during walking, and avoiding the decrease in anti-slip performance caused by wear on one side.

[0031] Furthermore: the shoe body 1 and the sole 2 are fixedly bonded by adhesives (using PU special adhesive with a peel strength ≥3N / mm). The middle of the sole 2 has a reserved movable groove 61 for installing the second anti-slip component 6, forming a full-area anti-slip layout of "basic anti-slip at the front and rear + adjustable anti-slip in the middle", covering the key stress areas of the forefoot, heel and arch.

[0032] As a further implementation of this solution, the first anti-slip component 5 includes multiple anti-slip protrusions 51. The anti-slip protrusions 51 extend along the width direction of the sole 2, and the top of the anti-slip protrusions 51 is fixedly connected to the bottom of the sole 2. The multiple anti-slip protrusions 51 are arranged at equal intervals, and the bottom of each of the multiple anti-slip protrusions 51 is provided with a groove 52. Gaps are formed between adjacent anti-slip protrusions 51 and between the anti-slip protrusions 51 and the reinforcing edge 3. The bottom of the anti-slip protrusions 51 is flush with the bottom of the reinforcing edge 3.

[0033] It should be noted that: multiple anti-slip ridges 51 extend along the width of the sole 2, and are fixedly connected to the bottom of the sole 2 at the top (using one-piece injection molding, with high connection strength). The equidistant arrangement design makes the friction force distribution more uniform. The anti-slip ridges 51 are made of wear-resistant PU material (with 15% silicone rubber particles added). The grooves 52 on the bottom can form a "deformation-rebound" effect when in contact with the ground. When walking, the grooves 52 are compressed and contracted, increasing the contact area with the ground; when lifting the foot, the grooves 52 rebound, expelling water or dust accumulated in the gaps and avoiding slippage caused by "water film lubrication".

[0034] Furthermore, the gaps formed between adjacent anti-slip ridges 51 and between the anti-slip ridges 51 and the reinforcing edge 3 can quickly drain water, mud, sand and other debris between the sole 2 and the ground. Especially on wet or muddy roads, the gaps can reduce the accumulation of debris on the sole 2, ensuring that the anti-slip ridges 51 are always in effective contact with the ground and maintaining basic anti-slip performance.

[0035] As a further implementation of this solution, the adjustment structure 64 includes a transmission support rod 641 disposed inside the movable groove 61 and located above the adjustment support plate 62. Multiple cams 642 are arranged at equal intervals on the outer side of the transmission support rod 641, and the cams 642 are fixedly connected to the transmission support rod 641. A threaded sleeve 643 is fixedly bonded to the middle of one side of the inner cavity of the shoe sole 2. An adjustment screw 644 is threadedly connected to the threaded sleeve 643. The end of the adjustment screw 644 extends into the movable groove 61. One end of the transmission support rod 641 is rotatably connected to one side of the shoe sole 2, and the other end of the transmission support rod 641 is fixedly connected to the end of the adjustment screw 644. The adjustment structure 64 also includes multiple sets of telescopic support rods 645 arranged at equal intervals on both sides of the transmission support rod 641. A return spring 646 is sleeved on the outer side of the telescopic support rod 645. The upper and lower ends of the telescopic support rod 645 and the return spring 646 are fixedly connected to the top of the inner cavity of the movable groove 61 and the top of the adjustment support plate 62, respectively.

[0036] It should be noted that the adjusting support plate 62 inside the movable groove 61 is precisely matched with the groove body specifications (gap ≤ 0.5mm), and the multiple anti-slip suction cups 63 fixed at the bottom (made of food-grade silicone material, Shore hardness 40A, adsorption force ≥ 2N / cup) extend into the anti-slip cavity 4. When the anti-slip suction cup 63 contacts the ground and is pressed, the air inside the suction cup is expelled, forming a negative pressure to adhere to the smooth ground (such as tiles, flooring), thus making up for the problem of insufficient anti-slip of traditional raised strips on smooth surfaces.

[0037] Furthermore: The adjustment structure 64 achieves the lifting and lowering adjustment of the anti-slip suction cup 63 through mechanical transmission. Rotating the adjustment screw 644 (the end of which is fixedly connected to the transmission support rod 641) causes the threaded sleeve 643 to engage with the threaded screw 644, driving the transmission support rod 641 to rotate. Multiple cams 642 on the outer side of the transmission support rod 641 rotate synchronously with it. When the protruding end of the cam 642 rotates downward, it pushes the adjustment plate 62 down along the movable groove 61, making the anti-slip suction cup 63 protrude from the bottom of the reinforced edge 3, enhancing the adsorption and anti-slip effect. Reverse rotation of the adjustment screw 644 causes the protruding end of the cam 642 to rotate upward, and the adjustment plate 62 rises under the action of the telescopic support rod 645 (which acts as a guide) and the return spring 646 (which provides rebound force), causing the anti-slip suction cup 63 to retract to be flush with the bottom of the anti-slip ridge 51, preventing rough ground from wearing down the anti-slip suction cup 63.

[0038] In summary, this PU women's shoe ensures structural stability through reinforced edge 3, the raised strips and gaps of the first anti-slip component 5 provide basic anti-slip, and the adjustable suction cups and mechanical adjustment of the second anti-slip component 6 enhance anti-slip in special scenarios. The collaboration of multiple components greatly improves anti-slip performance and adapts to the diverse ground environments of daily walking.

[0039] Work process: When walking on regular roads such as cement and asphalt, the sole 2 is in the initial state. At this time, the return spring 646 in the adjustment structure 64 is in the naturally extended state, pushing the adjustment support plate 62 to the upper position inside the movable groove 61. The top of the anti-slip suction cup 63 is fixedly connected to the adjustment support plate 62, and the bottom is flush with the bottom of the anti-slip ridge 51. When walking, the reinforced edge 3 contacts the ground, enhancing the overall stability of the sole 2. The multiple anti-slip ridges 51 in the first anti-slip component 5 are in direct contact with the ground, providing basic anti-slip force through material friction. The groove 52 at the bottom of the anti-slip ridge 51 is deformed by pressure, increasing the contact area and improving the friction effect. The gaps between adjacent anti-slip ridges 51 and between them and the reinforced edge 3 can promptly drain a small amount of water and dust from the contact surface, maintaining stable anti-slip.

[0040] When walking on smooth surfaces such as tiles and floors, it is necessary to enhance the anti-slip performance. Rotating the adjusting screw 644, which is threadedly connected to the threaded sleeve 643, will drive the transmission support rod 641 to rotate. When the transmission support rod 641 rotates, multiple cams 642 fixed on the outside rotate synchronously. The protruding end of the cam 642 presses down on the adjusting support plate 62, causing the adjusting support plate 62 to move downward along the movable groove 61. At this time, the telescopic support rod 645 is stretched, and the return spring 646 is stretched and stores energy. The adjusting support plate 62 drives multiple anti-slip suction cups 63 at the bottom to descend synchronously, so that the anti-slip suction cups 63 protrude from the bottom of the reinforced edge 3. When in contact with the ground, the anti-slip suction cups 63 are pressed to expel the internal air, forming a negative pressure to adhere to the smooth surface, which significantly enhances the anti-slip effect.

[0041] After returning to the normal road surface, the adjusting screw 644 is rotated in the opposite direction. The transmission support rod 641 drives the cam 642 to rotate in the opposite direction. The protruding end of the cam 642 leaves the adjusting support plate 62. The return spring 646, through its own rebound force, drives the adjusting support plate 62 to move upward along the movable groove 61 to reset. At the same time, the telescopic support rod 645 retracts to reset. The adjusting support plate 62 drives the anti-slip suction cup 63 to rise until the bottom of the anti-slip suction cup 63 is flush with the bottom of the anti-slip protrusion 51 again, restoring the normal anti-slip state and preventing the rough road surface from wearing down the anti-slip suction cup 63.

[0042] The entire process ensures basic anti-slip by using the first anti-slip component 5, while the second anti-slip component 6 flexibly adjusts the anti-slip strength according to the road surface conditions to achieve reliable anti-slip effects in different scenarios.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
