Description

Technical Field

[0001] This utility model belongs to the field of shoe sole technology, and specifically relates to a built-in rigid anti-slip and durable shoe sole. Background technology:

[0002] For a long time, people have proposed many technical solutions to address the issues of shoe soles being slip-resistant, drop-resistant, easy to walk on, adaptable to different road conditions, and durable. These solutions include changing the tread patterns and grooves of the soles, adding suction cups for drainage and slip resistance; using highly elastic materials and adding assistive devices (including air cushions) to increase rebound; adding spike plates or spike covers to the soles to adapt to icy and frozen roads; and changing wear-resistant materials to improve durability. However, regardless of the tread patterns and grooves, due to the different centers of gravity of each person when standing and walking, the wear points are located at different points, such as the front, back, or sides, rarely showing uniform wear. Over time, the slip resistance at the wear points decreases rapidly; changing materials to increase rebound has limited effectiveness with existing materials; adding additional assistive devices to the outside of the sole takes up space and affects aesthetics; air cushions are at risk of being punctured by sharp objects and becoming ineffective; adding spike plates or spike covers to the soles affects wearing comfort and is inconvenient to carry and store. Therefore, existing technologies have not been able to solve these problems in a comprehensive and rigid manner. Utility Model Content

[0003] This invention provides a rigid, integrated solution to the aforementioned problems by proposing a built-in rigid anti-slip and durable shoe sole.

[0004] This utility model proposes a built-in rigid anti-slip and durable shoe sole, which includes an upper shoe plate, a secondary support, a slip-aiding washer, a spring plate, a middle support, a friction block, an adjusting washer, a secondary cone pin, a middle cone pin, a lower shoe plate, a threaded bushing, a locking bolt, and a sealing plug.

[0005] The upper shoe plate is attached to the middle support and integrated with the lower shoe plate; the spring plate is connected to the upper part of the middle support and the sub-support; the slip-aiding washer is attached to the lower shoe plate; the lower end of the middle support is connected to the adjusting washer and the middle cone pin; the lower end of the sub-support is connected to the adjusting washer, the sub-cone pin, and the friction block; the lower shoe plate is connected to the threaded bushing and the sealing plug; the locking bolt is connected to the threaded bushing. The number of the center hole and corner holes on the spring plate is the same as that on the sub-support and the friction block.

[0006] The upper part of the upper shoe plate is provided with a concave cavity that is adapted to the sub-support, the middle support and the spring plate.

[0007] The upper part of the middle support is provided with an annular groove, the middle part with a frustoconical annular groove, and the lower end with a threaded hole, which is adapted to the spring plate, locking bolt and middle conical nail respectively.

[0008] The upper part of the sub-support is provided with an annular groove, the lower end is provided with a threaded hole, and the outer circle of the large end is provided with a chamfer angle, which is adapted to the spring plate, the sub-conical nail and the friction block respectively.

[0009] The spring plate has a polygonal shape with connecting holes in the center and corner directions, which are compatible with the central support and the sub-supports.

[0010] The end faces of the central and secondary conical nails are provided with small holes for disassembly and assembly, allowing for quick replacement of the conical nails; the conical nails are adapted to the adjusting washers to adjust the extension and retraction range of the conical nails.

[0011] The friction block has a large stepped hole with an inverted cone angle that matches the sub-support, and a small hole for disassembly and assembly at the lower end, so that the friction block can be fixed and quickly replaced.

[0012] The upper surface of the lower shoe plate is provided with a polygonal groove, the bottom surface is provided with a waist-shaped eccentric hole, the middle and corners are provided with mounting holes, and the outer side is provided with a sealing hole, which is adapted to the threaded bushing and sealing plug respectively, and can prevent dust and water.

[0013] The structure and its function are described as follows: When the sole of the shoe touches the ground, the upper shoe plate concentrates the weight of the person to the spring plate. The spring plate compresses and decomposes the pressure to the middle support and the secondary support, which in turn pushes the cone and friction block out of the sole. When the sole leaves the ground, the spring plate rebounds, pulling the cone and friction block back into the sole, thus constituting the extension and retraction movement of the cone and friction block when a person walks.

[0014] The same structure is independently placed at the forefoot and heel of the sole, and the size can be adjusted as needed in the specific implementation.

[0015] The above structure can be selected and adjusted as needed during implementation to adapt to different road conditions, including icy and frozen road conditions, ordinary road conditions, etc.

[0016] This utility model has the following advantages: 1. This utility model is equipped with a linkage structure of spring plate, central support, sub-support, central cone nail, sub-cone nail and friction block, so that the contact pressure between the cone tip and the friction block and the ground is centrally positioned and supported at multiple points. The force on the sole is always in a balanced state, which effectively prevents slippage in any direction and rigidly increases the anti-slip performance of the sole. 2. The spring plate in this invention rigidly increases the rebound force of the shoe sole, making walking easier and more comfortable. 3. The conical nails and friction blocks provided in this invention can be quickly replaced and updated, increasing the overall durability of the shoe sole. 4. This utility model can be implemented in various specific modes and is applicable to different road conditions. 5. The anti-slip assist structure of this utility model is set inside the sole of the shoe, saving space. Attached image description:

The above structure and its function are described as follows: When the sole of the shoe touches the ground, the upper shoe plate concentrates the weight of the body and transmits it to the spring plate. The spring plate compresses and decomposes the pressure to the middle support and the secondary support, which then pushes the cone and friction block out of the sole. When the sole leaves the ground, the spring plate rebounds and pulls the cone and friction block back into the sole.

[0026] The upper shoe plate (1) is attached to the middle support and integrated with the lower shoe plate; the spring plate is connected to the upper part of the middle support and the sub-support; the sliding washer is attached to the lower shoe plate; the lower end of the middle support is connected to the adjusting washer and the middle cone pin; the lower end of the sub-support is connected to the adjusting washer, the sub-cone pin and the friction block; the lower shoe plate is connected to the threaded bushing and the sealing plug; the locking bolt is connected to the threaded bushing. The number of the center hole and corner holes of the spring plate is the same as that of the sub-support and the friction block.

[0027] Preferably, the lower end of the upper shoe plate (1) is provided with a triangular cavity, which is adapted to the spring plate (4), the sub-support (2), and the middle support (5). The bottom of the cavity is fitted with the upper end of the middle support (5), and the shape is heat-sealed to the lower shoe plate (10).

[0028] Preferably, the sub-support (2) has an annular groove on the upper part and a threaded hole on the lower part for connecting the spring plate (4) and the sub-conical nail (8); the outer circle of the large end has a chamfered angle to prevent the friction block (6) from falling off; the material is lightweight plastic, so that it has a certain rigidity and reduces weight, while ensuring that it can be heat-sealed with the spring plate (4).

[0029] Preferably, the spring plate (4) is triangular in shape, with a central hole at the center of the triangle that matches the annular groove of the central support (5); and corner holes along the triangular direction that match the annular grooves of the secondary supports (2). High-quality spring steel plate is used as the material, and the elastic force is proportionally set to the body weight to ensure moderate rebound force and comfortable walking.

[0030] Preferably, the sliding washer (3) is made of high-quality steel, and after heat treatment and surface treatment, it ensures high hardness and high smoothness, so that the polygonal spring plate (4) can slide back and forth with it.

[0031] Preferably, the upper part of the middle support (5) is provided with an annular groove, and the lower part is provided with a threaded hole, which are respectively connected to the spring plate (4) and the middle conical nail (5); the middle part is provided with a frustoconical annular groove that is adapted to the frustoconical part of the locking screw (12). It is made of lightweight plastic, so that it has a certain rigidity and reduces weight, while ensuring that it can be heat-sealed with the spring plate (4).

[0032] Preferably, both the sub-taper (2) and the middle taper (3) are made of high-quality alloy structural steel, and high hardness and high wear resistance are ensured after heat treatment. Two small holes are provided on the end face for quick installation and removal, and coordinate with the adjusting washer (7) to adjust the telescopic distance of the taper.

[0033] Preferably, the friction block (6) is the main force-bearing and wear-bearing component, so it is made of wear-resistant rubber. The lower step hole is provided with an inverted cone angle that matches the sub-support (2), and the lower end is provided with two small holes for replacement and renewal, thereby increasing the durability and service life of the shoe sole.

[0034] Preferably, the lower shoe plate (10) is made of foamed lightweight material to reduce weight; the upper end surface is provided with a triangular groove that matches the shape of the spring plate (4), and the inner cavity size of the groove is larger than the outer size of the spring plate (4) to ensure that the compression and extension of the polygonal spring plate (4) is not interfered with; a center hole and three corner holes are provided at the center and corners, which are fitted with the outer circle of the sub-support (2) and the middle support (5) with clearance; three eccentric waist-shaped stepped holes are provided at the lower end, which are fitted with the inner side of the outer circle of the friction block (6) with clearance, while leaving a moderate space with the outer side of the outer circle, so that when the spring plate (4) is compressed downward, the three friction blocks (6) move downward and extend to the outer side of the triangle, increasing the triangle support angle and support surface, and further improving stability and anti-slip performance; four sealing holes are provided on the outer side for installing threaded bushings (11), locking screws (12) and sealing plugs (13).

[0035] One end of the locking screw (12) is a frustoconical shape, which is adapted to the frustoconical annular groove in the middle of the central support (5). When the locking screw (12) tightens against the central support (5), the spring plate (4) is compressed and fails, and all the spikes cannot protrude from the sole of the shoe. This allows the shoe to be temporarily converted from walking on icy and frozen ground to walking on indoor or outdoor ordinary ground, preventing the spikes from damaging the ground or floor.

[0036] The above structures are independently located at the forefoot and heel of the shoe sole.

[0037] The above embodiments are applicable to various wet and slippery road surfaces, especially icy and frozen soil roads, and are the preferred mode of this utility model. Based on this mode, the cone nail, central support, adjusting washer and locking device can be eliminated, thus forming a lightweight mode suitable for ordinary road surfaces.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
