Abstract
Description
Technical Field
[0001] This utility model belongs to the field of footwear manufacturing technology, and specifically refers to an anti-slip shoe sole. Background Technology
[0002] As a crucial component of footwear, the sole not only supports the body's weight and cushions the impact of walking, but also needs to provide appropriate anti-slip properties depending on the usage scenario. In rainy, snowy, or icy conditions, a sole with an anti-slip structure can significantly increase friction, reduce the risk of slipping, and ensure the wearer's safety.
[0003] Existing anti-slip sole designs have a significant drawback: they cannot quickly and easily switch between anti-slip modes. Taking soles with anti-slip studs as an example, the studs are typically permanently protruding from the sole surface, remaining protruding even in situations where anti-slip functionality is not needed. This not only causes abnormal noises and accelerated wear during walking but also affects walking comfort due to uneven contact between the studs and the ground, and may even damage the ground. While some replaceable anti-slip soles attempt to address this issue, their complex structures require tools to disassemble parts, making the process cumbersome and time-consuming, and failing to meet users' actual needs for quick switching between different scenarios. Therefore, designing a sole structure that can flexibly switch between anti-slip and normal modes and is easy to operate has become a pressing technical challenge in this field. Utility Model Content
[0004] This invention uses a magnetically fixed, flip-up anti-slip module to quickly switch between anti-slip and flat states on the sole of the shoe, thereby solving the problems mentioned in the background art.
[0005] The purpose of this utility model is achieved as follows: a non-slip shoe sole, comprising:
[0006] The outsole has mounting grooves on its outer surface corresponding to the forefoot.
[0007] The anti-slip module includes a base plate that matches the mounting groove and a plurality of anti-slip pins fixedly connected to the outside of the base plate;
[0008] The magnetic fixing assembly includes a moving magnet embedded inside the substrate and a fixed magnet disposed at the bottom of the mounting groove and corresponding to the moving magnet.
[0009] The upper and lower surfaces of the moving magnet are coplanar with the inner and outer surfaces of the substrate, respectively. The bottom of the mounting groove is provided with nail slots that correspond one-to-one with the anti-slip nails. The substrate can selectively embed the anti-slip nails into the nail slots or expose the anti-slip nails to the outside of the shoe sole by flipping the substrate.
[0010] The present invention is further configured such that an elastic flange is provided on the periphery of the substrate, and a slot adapted to the elastic flange is provided on the side wall of the mounting groove.
[0011] The present invention is further configured such that the fixed magnet is an annular structure arranged around the nail groove.
[0012] The present invention is further configured such that the fixed magnet is divided into a first pole region and a second pole region along the horizontal direction.
[0013] The present invention is further provided that the first polar region and the second polar region are respectively provided with visual identifiers.
[0014] The present invention is further configured such that the exposed surface of the moving magnet is covered with a non-magnetic protective layer.
[0015] The present invention is further provided that the outer surface of the sole is provided with at least one auxiliary groove communicating with the mounting groove, the auxiliary groove being used to accommodate the finger force to disassemble the anti-slip module.
[0016] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:
[0017] 1. By combining the flip-up anti-slip module with the magnetic fixing component, the anti-slip studs can be quickly switched between exposed and stored states, solving the problem that traditional anti-slip soles cannot balance anti-slip and comfort, and significantly improving the adaptability of the soles to different scenarios.
[0018] 2. The adaptive structure of the elastic flange and the slot ensures a stable connection of the anti-slip module in the mounting slot, preventing the module from loosening or falling off during use and improving the reliability of the anti-slip structure.
[0019] 3. The auxiliary grooves on the sole provide a point of leverage for the fingers, facilitating quick disassembly of the anti-slip module and improving the ease of maintenance of the anti-slip structure. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :
[0025] Example 1:
[0026] This embodiment provides a non-slip shoe sole, including:
[0027] The sole 1 has a mounting groove 2 on its outer surface corresponding to the forefoot;
[0028] The anti-slip module 3 includes a base plate 30 that matches the mounting groove 2 and a plurality of anti-slip nails 31 that are fixedly connected to the outside of the base plate 30.
[0029] The magnetic fixing assembly 4 includes a moving magnet 40 embedded inside the substrate 30 and a fixed magnet 41 disposed at the bottom of the mounting groove 2 and corresponding to the moving magnet 40;
[0030] The upper and lower surfaces of the moving magnet 40 are coplanar with the inner and outer surfaces of the substrate 30, respectively. The bottom of the mounting groove 2 is provided with nail grooves 5 corresponding to the anti-slip nails 31. The substrate 30 can selectively embed the anti-slip nails 31 into the nail grooves 5 or expose the anti-slip nails 31 to the outside of the sole 1 by flipping the substrate 30.
[0031] The sole 1, as the basic carrier of the anti-slip sole 1, not only provides the basic functions of supporting the weight of the human body and cushioning the impact of walking, but also provides installation space for the anti-slip module 3 and the magnetic fixing component 4. At the same time, when the anti-slip studs 31 are stored, they serve as a flat walking contact surface.
[0032] The mounting groove 2 provides installation and positioning space for the anti-slip module 3, ensuring that the anti-slip module 3 can be accurately installed on the forefoot of the sole 1. Simultaneously, with the anti-slip studs 31 retracted, the anti-slip module 3 is embedded within it, maintaining the flatness of the sole 1 surface. The mounting groove 2 is a recess formed on the forefoot of the outer surface of the sole 1, its shape matching the base plate 30 of the anti-slip module 3. The bottom of the groove has stud slots 5 corresponding one-to-one with the anti-slip studs 31 for accommodating them.
[0033] The anti-slip module 3 exposes and stores the anti-slip studs 31 by flipping, thus providing anti-slip function in scenarios where anti-slip is needed, and keeping the sole 1 flat in scenarios where anti-slip is not needed, improving the flexibility and comfort of use. The anti-slip module 3 consists of a base plate 30 and multiple anti-slip studs 31. The shape of the base plate 30 matches the mounting groove 2 and can be embedded in the mounting groove 2; the anti-slip studs 31 are fixedly connected to the outside of the base plate 30 and can be selectively embedded in the stud groove 5 or exposed on the outside of the sole 1.
[0034] The base plate 30 serves as the mounting carrier for the anti-slip studs 31 and cooperates with the mounting groove 2 of the shoe sole 1 to position and fix the anti-slip module 3. Flipping the base plate 30 switches the state of the anti-slip studs 31. The base plate 30 is generally a plate-shaped structure matching the mounting groove 2, with a moving magnet 40 embedded inside. The upper and lower surfaces of the moving magnet 40 are coplanar with the inner and outer surfaces of the base plate 30, respectively. Multiple anti-slip studs 31 are connected to the outer side of the base plate 30, and the base plate 30 can be fixedly connected to the anti-slip studs 31 by welding, riveting, or high-strength bonding. The base plate 30 is connected and fixed to the shoe sole 1 through the magnetic attraction between the moving magnet 40 and the fixed magnet 41 in the mounting groove 2.
[0035] In anti-slip mode, the anti-slip studs 31 protrude from the outside of the sole 1, increasing the friction between the sole 1 and the ground, preventing slippage during walking, and providing a good anti-slip effect. The anti-slip studs 31 are generally rod-shaped, with one end fixedly connected to the outside of the base plate 30, and the other end being sharp or textured to enhance grip on the ground; multiple studs are evenly distributed on the outside of the base plate 30, corresponding one-to-one with the stud slots 5 at the bottom of the mounting groove 2. The anti-slip studs 31 are fixedly connected to the outside of the base plate 30, exposed on the outside of the sole 1 in anti-slip mode, and embedded in the stud slots 5 at the bottom of the mounting groove 2 in storage mode.
[0036] The magnetic fixing assembly 4 is used to achieve quick connection and fixation between the anti-slip module 3 and the sole 1. Through the mutual attraction between the moving magnet 40 and the fixed magnet 41, the anti-slip module 3 can be stably fixed when flipped to any state, preventing it from loosening or falling off during use. The magnetic fixing assembly 4 consists of a moving magnet 40 embedded in the base plate 30 and a fixed magnet 41 located at the bottom of the mounting groove 2.
[0037] The moving magnet 40 and the fixed magnet 41 work together to generate magnetic force, achieving adsorption and fixation between the anti-slip module 3 and the shoe sole 1. During the flipping process of the anti-slip module 3, the magnetic force with the fixed magnet 41 is maintained, ensuring stable fixation of the anti-slip module 3 in different states. The moving magnet 40 is generally a block structure, with its upper and lower surfaces coplanar with the inner and outer surfaces of the substrate 30, respectively. That is, the moving magnet 40 is completely embedded inside the substrate 30, and its surface is flush with the surface of the substrate 30, not affecting the fit between the substrate 30 and the mounting groove 2, or the flipping operation of the anti-slip module 3. The moving magnet 40 can be fixed inside the substrate 30 by injection molding or high-strength adhesive; the fixed magnet 41 can be pre-embedded in the bottom of the mounting groove 2 during the injection molding of the shoe sole 1, or fixed to the bottom of the groove through an adhesive process, ensuring that the magnet does not shift during long-term use.
[0038] The fixed magnet 41 and the moving magnet 40 attract each other, providing a fixed magnetic force for the anti-slip module 3, thus keeping the anti-slip module 3 stable within the mounting groove 2. The fixed magnet 41 is fixedly installed at the bottom of the mounting groove 2 of the sole 1, and its position strictly corresponds to that of the moving magnet 40 to ensure that an effective magnetic force can be generated between them. During the manufacturing process of the sole 1, the fixed magnet 41 is embedded into the bottom of the mounting groove 2 using a mold, or it is bonded to the bottom of the groove using high-strength adhesive, ensuring that the fixed magnet 41 is firmly connected to the sole 1 and will not shift or fall off during use.
[0039] In this embodiment, when the anti-slip function is required, the user holds the base plate 30 of the anti-slip module 3, lifts the anti-slip module 3 from the mounting groove 2, and flips it 180°, so that the inner and outer sides of the base plate 30 interchange positions, realizing the switching between the exposed state and the embedded state of the anti-slip stud 31. During the flipping process, the magnetic direction between the moving magnet 40 embedded in the base plate 30 and the fixed magnet 41 at the bottom of the mounting groove 2 remains unchanged. When the anti-slip stud 31 is flipped to the anti-slip mode exposed to the outside of the shoe sole 1, the moving magnet 40 and the fixed magnet 41 attract each other. Under the action of magnetic attraction, the base plate 30 is tightly attached to the bottom of the mounting groove 2. At the same time, the elastic flange 6 on the periphery of the base plate 30 is squeezed and embedded in the slot 7, further enhancing the fixing effect. At this time, the anti-slip stud 31 protrudes from the outer surface of the shoe sole 1, increasing the friction with the ground and realizing the anti-slip function.
[0040] When entering a scenario where anti-slip is not required, grasp the base plate 30 of the anti-slip module 3 again, lift the anti-slip module 3 and rotate it 180°, so that the anti-slip studs 31 are embedded in the stud grooves 5 at the bottom of the mounting groove 2. At this time, the moving magnet 40 and the stationary magnet 41 attract each other again through magnetic force, fixing the base plate 30 in the mounting groove 2, and the surface of the sole 1 returns to flat, preventing the anti-slip studs 31 from digging into the foot and improving walking comfort. The entire switching process does not require disassembling parts and can be completed with just a simple flipping operation.
[0041] Example 2:
[0042] This embodiment provides an anti-slip shoe sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0043] The substrate 30 has an elastic flange 6 on its periphery, and the mounting groove 2 has a slot 7 on its side wall that is adapted to the elastic flange 6.
[0044] In this embodiment, the elastic flange 6 is a raised annular structure surrounding the periphery of the substrate 30, which can be made of rubber or thermoplastic elastomer. Its cross-section can be semi-circular or trapezoidal. It is bonded to the periphery of the substrate 30 by vulcanization or integral injection molding, and can generate radial elastic deformation when compressed. The slot 7 is a recessed groove structure opened on the side wall of the mounting groove 2, which matches the shape and size of the elastic flange 6. When the anti-slip module 3 is installed into the mounting groove 2 of the sole 1, the elastic flange 6 is compressed and generates elastic deformation, smoothly sliding into the slot 7. After entering the appropriate position in the slot 7, the elastic flange 6 returns to its original shape and is embedded in the slot 7 to form a mechanical engagement. The purpose of this design is to provide additional mechanical fixing force for the anti-slip module 3 through the cooperation of the elastic flange 6 and the slot 7. Together with the magnetic fixing component 4, it enhances the stability of the connection between the anti-slip module 3 and the sole 1, preventing the anti-slip module 3 from shifting or falling out under the conditions of walking vibration, external impact, etc., ensuring that the anti-slip stud 31 can stably perform its anti-slip function in the working state and keep the sole 1 flat in the storage state. At the same time, the elastic structure also makes the disassembly and installation of the anti-slip module 3 smoother and more convenient.
[0045] Example 3:
[0046] This embodiment provides an anti-slip shoe sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0047] The fixed magnet 41 is a ring structure arranged around the nail groove 5.
[0048] In this embodiment, the fixed magnet 41 adopts a ring-shaped structure design surrounding the nail slot 5, aiming to achieve a stable and omnidirectional fixation effect for the anti-slip module 3 through uniformly distributed magnetic force. When the anti-slip module 3 is flipped, the ring-shaped fixed magnet 41 can generate magnetic forces with the moving magnet 40 in the substrate 30 in multiple directions, avoiding tilting or displacement of the anti-slip module 3 due to uneven local force. At the same time, this ring structure allows the anti-slip nail 31 to accurately align with the nail slot 5, ensuring accurate alignment of the anti-slip nail 31 with the nail slot 5 whether in the exposed state of anti-slip mode or the embedded state of storage mode, improving the accuracy and stability of installation and switching. In addition, the ring layout makes full use of the space of the mounting slot 2, enhancing the reliability of the magnetic fixing component 4 without increasing the thickness and volume of the sole 1, and providing durable and balanced fixation support for the anti-slip module 3.
[0049] Example 4:
[0050] This embodiment provides an anti-slip shoe sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0051] The fixed magnet 41 is divided into a first pole region 8 and a second pole region 9 along the horizontal direction.
[0052] In this embodiment, the design of dividing the fixed magnet 41 into a first pole region 8 and a second pole region 9 along the horizontal direction aims to create directional magnetic attraction through polarity distribution, ensuring precise alignment and stable fixation of the anti-slip module 3 during flipping. Structurally, the annular fixed magnet 41 is divided into two opposite pole regions, the first pole region 8 and the second pole region 9, in the horizontal plane. This partitioning method allows the fixed magnet 41 to form a directional magnetic field distribution at the bottom of the mounting groove 2. When the substrate 30 drives the moving magnet 40 to flip, the moving magnet 40 must correctly correspond to the polarity region of the fixed magnet 41. For example, the N pole of the moving magnet 40 must correspond to the second pole region 9 of the fixed magnet 41 to generate the strongest attraction force, thereby guiding the anti-slip module 3 to complete the installation in the only correct direction and avoiding misalignment or magnetic failure of the anti-slip nail 31 and the nail groove 5 due to incorrect flipping direction. In addition, the polarity partition design can automatically reject incorrect installation orientation through the magnetic repulsion effect. When the anti-slip module 3 is flipped in the wrong direction, the same pole areas of the moving magnet 40 and the fixed magnet 41 generate a repulsive force, preventing the substrate 30 from completely fitting into the mounting groove 2, further improving the fault tolerance of operation, and ensuring that the anti-slip module 3 can be tightly fixed by magnetic force after flipping, and that the anti-slip nail 31 can be accurately aligned with the nail groove 5, realizing a reliable switch between the anti-slip state and the storage state.
[0053] Example 5:
[0054] This embodiment provides an anti-slip shoe sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0055] The first polar region 8 and the second polar region 9 are each provided with a visual identifier 10.
[0056] In this embodiment, visual markings 10 are provided in the first pole area 8 and the second pole area 9 respectively. The purpose is to help users quickly and accurately flip the anti-slip module 3 to the correct position through intuitive visual cues, avoiding poor magnetic attraction or insecure fixation of the anti-slip module 3 due to incorrect installation orientation. The visual markings 10 may be coatings of different colors, such as red for the first pole area 8 and blue for the second pole area 9, or patterns of different shapes, such as a circular pattern for the first pole area 8 and a square pattern for the second pole area 9. They may also be marked with different words or symbols, such as "N" for the first pole area 8 and "S" for the second pole area 9. These markings can be fixed to the surface of the fixed magnet 41 by printing, spraying, film application, or molding, ensuring that they are not easily detached or worn during use and remain clearly visible at all times. This effectively reduces the operational error rate, improves the efficiency and accuracy of installing and switching the anti-slip module 3, and allows users to use the anti-slip sole 1 more conveniently and reliably.
[0057] Example 6:
[0058] This embodiment provides an anti-slip shoe sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0059] The exposed surface of the moving magnet 40 is covered with a non-magnetic protective layer.
[0060] In this embodiment, the design of covering the exposed surface of the moving magnet 40 with a non-magnetic protective layer aims to improve the reliability and service life of the magnetic fixing component 4 through the dual functions of isolation protection and functional optimization. The non-magnetic protective layer can be made of non-magnetic materials such as engineering plastics, epoxy resin, or stainless steel sheets with high hardness, and can be tightly attached to the exposed surface of the moving magnet 40 by means of spray curing, injection molding, or bonding. Its functions are manifested in the following ways: Firstly, the non-magnetic material can prevent the moving magnet 40 from directly contacting the external environment, preventing water vapor, dust, and corrosive substances from eroding the magnet and causing demagnetization or rust. Especially when the anti-slip module 3 frequently flips and switches states, the protective layer can buffer the friction and collision with the fixed magnet 41 or the mounting groove 2, reducing wear on the magnet surface. Secondly, the protective layer can isolate the moving magnet 40 from direct adsorption with metal foreign objects, preventing the accumulation of foreign objects from affecting the magnetic attraction accuracy. For example, the adsorption of iron filings can cause the distance between the moving magnet 40 and the fixed magnet 41 to increase and the magnetic force to weaken. At the same time, the smooth surface of the protective layer can reduce the probability of dirt adhesion, ensuring the flatness of the fit between the moving magnet 40 and the fixed magnet 41 during the flipping process, maintaining a stable magnetic attraction strength, so that the anti-slip module 3 can maintain a reliable fixing effect in both the installation and storage states.
[0061] Example 7:
[0062] This embodiment provides an anti-slip shoe sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0063] The outer surface of the sole 1 is provided with at least one auxiliary groove 11 that communicates with the mounting groove 2. The auxiliary groove 11 is used to accommodate the finger force to disassemble the anti-slip module 3.
[0064] In this embodiment, the auxiliary groove 11 can be designed as an arc-shaped or U-shaped recessed structure, with dimensions adapted to the thickness of a human finger, and depth and width sufficient to ensure easy insertion and application of force. The purpose of this design is to provide a point of leverage for the user to disassemble the anti-slip module 3, solving the problem of difficulty in disassembling the anti-slip module 3 due to its tight fit and magnetic fixation with the sole 1. When it is necessary to switch the state of the anti-slip module 3, the user can insert their fingers into the auxiliary groove 11 and apply external force through actions such as prying or pulling to break the magnetic attraction and locking structure 7 between the anti-slip module 3 and the sole 1, allowing the anti-slip module 3 to detach from the mounting groove 2 for easy flipping. The connection between the auxiliary groove 11 and the mounting groove 2 does not affect the stability of the anti-slip module 3 after installation, and significantly improves the convenience and comfort of user operation without altering the overall structural strength and appearance of the sole 1, avoiding damage to the anti-slip module 3 or a decline in user experience due to difficulty in disassembly.
[0065] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
