[0014] Based on technical solution 8 or 9, technical solution 10: the heel upper and the connecting piece are fixed together by sewing, hot melting and / or bonding.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] Technical solution one provides a footwear product with a press-to-open heel, the footwear product including a body, a rotating component, a ratchet pressing component, and a heel upper. The rotating component is mounted on the body, and the rotating part of the rotating component can rotate relative to the body; the heel upper is fixed to the rotating part and can rotate with the rotating part relative to the body, thereby opening the shoe opening to a position for putting on and taking off, or closing it to a position to restrain the user's ankle.

[0017] The ratchet pressing component is used to open and close the heel counter by pressing and rotating it. By pressing the heel counter in a preset direction, the counter stops between a first and a second preset position, where the first position is the open position and the second position is the closed position. The ratchet pressing component uses a ratchet-tooth coordinated pressing switching mechanism, similar to the pressing structure of a ballpoint pen. Pressing allows its output end to switch between different positions and stop at that position. The challenge in combining this ratchet pressing component with the rotating component lies in the fact that when the user operates the heel counter, the force is transmitted to the rotating component, and then to the ratchet pressing component. The output end of the ratchet pressing component needs to be able to both push the rotating component to open and pull it back to prevent it from closing when its position is fixed. The connection with the output end of the ratchet pressing component will detach. To address this, in this technical solution, a connecting part is provided at the output end of the ratchet pressing component, and a limiting flange is provided on the connecting part. At the same time, a connecting arm is provided on the rotating part, and a through groove is provided on the connecting arm. The connecting part can pass through the through groove on the connecting arm, and the two limiting flanges provided on it are located on the upper and lower sides of the connecting arm respectively. Since the size of the limiting flange is larger than the width of the through groove, the connecting part will not detach from the through groove. The limiting flange can push and hold the rotating part. When the heel upper is in the first position, it holds the heel upper to prevent it from tilting backward. When the heel upper is in the second position, it also holds the heel upper, so that the heel upper and the forefoot upper work together to restrain the user's ankle and prevent the footwear from coming loose.

[0018] Therefore, when using this footwear product, users can easily switch between the first and second positions of the heel upper by pressing it, making the putting-on and taking-off process simpler.

[0019] In technical solution two, the ratchet pressing assembly includes a housing, an upper ratchet, a lower ratchet, and an elastic element. The inner wall of the housing has several stopping positions, including a first stopping position and a second stopping position with different heights. A stopping arm is provided on the upper ratchet, which abuts against either the first or second stopping position under the action of the elastic element, thus allowing the upper ratchet, as the output end, to achieve different extension lengths. Since the first stopping position is higher than the second stopping position, the rotating component corresponding to the first stopping position rotates backward, with the heel surface in a first position; the rotating component corresponding to the second stopping position rotates forward, with the heel surface in a second position. The lower ratchet is fixed to the housing. Ratchets are provided at the mating positions on both the upper and lower ratchets. Through the inclined surface engagement between the ratches, the lower ratchet can push the upper ratchet, converting its linear motion into circumferential rotation. Each time the upper ratchet is pressed, it rotates by a preset angle, causing its stopping arm to switch abut against the first or second stopping position. Compared to conventional ratchet pressing components, in this technical solution, the upper ratchet itself serves as both the output and input end of the ratchet pressing component. Therefore, the upper ratchet itself needs to be able to perform linear motion and circumferential rotation. Thus, the size of the part of the connecting portion located in the through groove is designed to allow the connecting portion to rotate relative to the through groove, thereby preventing the rotation of the upper ratchet from affecting the connection between the connecting portion and the rotating component.

[0020] In technical solution three, the part of the connecting part located in the through groove is set as a cylinder, and the outer diameter of the cylinder is smaller than the width of the through groove, which can ensure that the rotation of the upper ratchet relative to the outer shell and the rotating part is not affected.

[0021] In technical solution four, the outer shell includes an upper shell and a lower shell that are fixedly connected to each other, which facilitates the assembly of the upper ratchet, the lower ratchet and the elastic element into the outer shell.

[0022] In technical solution five, the heel upper includes the heel part on the rear side and the side wings that extend forward on both sides in the width direction and at least partially overlap with the forefoot upper. This design can better wrap the user's ankle when the shoe opening is closed, increasing the contact area and fit between the shoe opening and the ankle, making the footwear more stable and less likely to come loose during wear, while also improving the overall aesthetics and comfort of the shoe.

[0023] In technical solution six, the base adopts a first base body and a second base body arranged along the width direction. The two ends of the rotating component are respectively rotatably connected to them around the first axis. Furthermore, ratchet pressing components are respectively set on the outer sides of the walls on both sides of the heel part of the sole and connected to the connecting arms of the rotating component. This makes the rotating component more evenly stressed during rotation, avoiding problems such as uneven rotation or component damage caused by unilateral stress. This ensures the stability and reliability of the opening and closing action of the heel upper, and improves the overall performance and service life of the footwear product.

[0024] In technical solution seven, a connecting piece is provided on the rotating component, and the heel upper is fixed to the connecting piece. The connection between the connecting piece and the heel upper can be on the side of the heel upper, thereby increasing the connection area between the rotating component and the heel upper. Since the user operates the heel upper itself when opening and closing it, this connection structure can improve the strength of the connection between the heel upper and the rotating component. This prevents the heel upper from deforming due to excessive elasticity of the elastic component, which prevents the upper ratchet from being pressed down and the rotating component from rotating. The connecting piece can also connect to the side wings of the heel upper. More connection points improve the connection stability between the heel upper and the rotating component, making the heel upper less prone to deformation. During normal wear, the rotating component will fix the position of the side wings of the heel upper, preventing them from spreading outwards, thereby improving the heel upper's fit around the user's foot.

[0025] In technical solution eight, the rotating component is a straight rod. Therefore, the first and second seats are located at the rear end of the sole to avoid the rotating component protruding from the heel of the sole, which would cause discomfort when wearing the shoe. The straight rod-shaped rotating component has low manufacturing cost and is easy to assemble into a rotating component.

[0026] In technical solution nine, the rotating component is a curved rod, and the first and second seats are located on both sides of the rear of the sole. The curved rod design increases the support area of ​​the rotating component, improves the rotational stability of the heel upper, and provides a larger adjustment range, making it easier to put on and take off the shoes.

[0027] In technical solution ten, the heel upper and the connecting piece are fixed together by sewing, hot melting and / or bonding. The selection or combination of multiple fixing methods can ensure that the connection between the heel upper and the connecting piece is firm and reliable according to different materials, processes and design requirements, avoid the separation of the upper and the connecting piece during use, and ensure the overall quality and service life of the footwear products.

[0045] Example 1

[0046] Embodiment 1 of this utility model relates to a footwear product with a press-to-open heel, as shown in the following figure. Figure 1 It shows the state of the heel upper 9 of the footwear product when closed, and also refers to... Figure 2 It shows the state of the heel upper 9 of the footwear product when it is open.

[0047] Reference Figure 1 and Figure 2 The footwear product mainly includes a body 1, a rotating component 5, a ratchet pressing component 8, and a heel upper 9. Of course, in addition to the above components, the footwear product may also include shoelaces, decorative parts, etc., which can be provided according to actual needs. It should be noted that the thickness direction referred to in this specification and claims is the vertical direction indicated in the drawings, the width direction is the horizontal direction indicated in the drawings, and the length direction is the front-back direction indicated in the drawings.

[0048] The main body 1 includes a sole 2 and a forefoot upper 3. The forefoot upper 3 is attached to the sole 2 and cooperates with the sole 2 to form a shoe cavity with an opening 4. The sole 2 has a conventional structure, which can be formed by combining an outsole and a midsole. The outsole can be made of a wear-resistant material such as nylon or rubber, and the midsole can be made of a polymer foam material, such as EVA, to provide better rebound and cushioning performance. The forefoot upper 3 can be composited and fixed to the sole 2 by sewing, gluing, or other methods. The material of the forefoot upper 3 can be mesh, foam, etc. (See reference...) Figure 1 and Figure 2 The forefoot upper 3 roughly corresponds to the forefoot and arch positions of the sole 2, with some edges extending obliquely to the heel. An opening 4 is formed on the back side of the forefoot upper 3. The forefoot upper 3 and the sole 2 work together to form a shoe cavity. The opening 4 is connected to the shoe cavity, and the user's foot can be inserted into the shoe cavity through the opening 4.

[0049] Clearly, the aforementioned body 1 provides a space to accommodate the user's foot, but it does not adequately restrain the user's heel, causing the user's foot to easily slip out of the shoe cavity. Therefore, this footwear product is equipped with a rotating component 5 and a heel counter 9.

[0050] Reference Figure 3 , Figure 4 and Figure 5 The rotating assembly 5 includes a base 6 and a rotating component 7; the base 6 is fixedly connected to the rear of the sole 2; the rotating component 7 is rotatably mounted on the base 6 about a first axis extending in the width direction, and is provided with a connecting arm 10 extending in the length direction; the connecting arm 10 is provided with a through groove 11 extending in its extension direction.

[0051] Reference Figure 3 In this embodiment, the base 6 includes a first base 24 and a second base 25 arranged along the width direction; the two ends of the rotating member 7 in the width direction are respectively rotatably connected to the first base 24 and the second base 25 around the first axis, and both ends of the rotating member 7 in the width direction are provided with the connecting arm 10. A connecting piece 26 extending upward along the thickness direction is provided at the middle position of the rotating member 7 in the width direction, and the heel upper 9 is fixed to the connecting piece 26.

[0052] Reference Figure 1 , Figure 2 and Figure 3 The first seat 24 and the second seat 25 are fixed to the rear end of the sole 2; the rotating member 7 is a straight rod and is located between the first seat 24 and the second seat 25.

[0053] Specifically, in this embodiment, both the first seat 24 and the second seat 25 are fixed at the rear end of the sole 2. This is because the rotating component 7 is set as a straight rod, and to prevent the rotating component 7 from passing through the heel of the sole 2, the first seat 24 and the second seat 25 need to be positioned as far back as possible. A pivot protruding in the left-right direction is provided at the middle of the inner surface of the first seat 24 and the second seat 25, and a shaft hole recessed in the left-right direction is provided at the middle of both end surfaces of the rotating component 7. The pivots of the first seat 24 and the second seat 25 can be inserted into the corresponding shaft holes, thereby allowing the rotating component 7 to be rotatably connected to the first seat 24 and the second seat 25. The line connecting the pivots of the first seat 24 and the second seat 25 at this time is the aforementioned first axis. The base 6 employs a first seat 24 and a second seat 25 arranged along the width direction. The two ends of the rotating component 7 are rotatably connected to them around a first axis. Furthermore, ratchet pressing components 8 are respectively installed on the outer sides of the heel portion 22 of the sole 2 along the width direction, connecting to the connecting arms 10 of the rotating component 7. This ensures more balanced force distribution on the rotating component 7 during rotation, avoiding problems such as uneven rotation or component damage caused by unilateral force. This guarantees the smoothness and reliability of the opening and closing action of the heel upper 9, improving the overall performance and lifespan of the footwear product. The rotating component 7 is a straight rod; therefore, the first seat 24 and the second seat 25 are located at the rear end of the sole 2, preventing the rotating component 5 from protruding from the heel position of the sole 2 and causing discomfort. The straight rod shape of the rotating component 7 results in lower manufacturing costs and facilitates assembly to form the rotating component 5.

[0054] The connecting piece 26 is disposed on the rotating component 7. The connecting piece 26 can be made of the same material as the forefoot upper 3 or the heel upper 9, but it is required to have structural stability that is not easily deformed, such as synthetic leather. The connecting piece 26 can be fixed to the rotating component 7 by means of bonding, heat fusion, etc. For example, when the rotating component 7 is plastic, it can be fixed by heat fusion. The connecting piece 26 is disposed on the rotating component 7, and the heel upper 9 is fixed to the connecting piece 26. The connection position between the connecting piece 26 and the heel upper 9 can be on the side of the heel upper 9, thereby increasing the connection area between the rotating component 7 and the heel upper 9. At the same time, since the part operated by the user when opening and closing the heel upper 9 is the heel upper 9 itself, this connection structure can improve the strength of the connection between the heel upper 9 and the rotating component 7, and prevent the heel upper 9 from deforming because the elastic force of the elastic element 17 is too large when the heel upper 9 is turned, and the upper ratchet 15 cannot be pressed, resulting in the rotating component 7 not being able to rotate. Among them, the connecting piece 26 can also be connected to the side wing 23 of the heel upper 9. The more connecting parts 12 improve the connection stability between the heel upper 9 and the rotating part 7, making the heel upper 9 less prone to deformation. At the same time, during normal wear, the rotating part 7 will fix the position of the side wing 23 of the heel upper 9 to prevent the side wing 23 from opening outward, thereby improving the fit of the heel upper 9 to the user's foot.

[0055] The rotating member 7 has connecting arms 10 at both its left and right ends. These connecting arms 10 extend approximately along the length of the footwear product and are located on the front side of the first base 24 and the second base 25. It is readily understood that since the connecting arms 10 need to engage with the external ratchet pressing assembly 8, they must be positioned on the outside of the rotating member 7 and must not interfere with the first base 24 and the second base 25 of the base 6. Therefore, in this embodiment, outwardly extending, arc-shaped forming portions can be provided at both ends of the rotating member 7. These forming portions can rotate around a first axis along the outer peripheral surface of the first base 24 and the second base 25, while the connecting arms 10 are located on the surface of these forming portions facing away from the first base 24 and the second base 25. (Refer to...) Figure 5 The connecting arm 10 is provided with a through groove 11 that runs vertically through the arm. The front end of the through groove 11 can be set as an open structure to facilitate the engagement of the connecting arm 10 with the output end of the ratchet 20 mounting assembly.

[0056] Reference Figure 1 and Figure 2 The heel upper 9 is fixed to the rotating member 7 and is adapted to stop relative to the base 6 at a preset first position and a second position as the rotating member 7 stops. When stopped, it cooperates with the forefoot upper 3 to form a shoe opening together with the shoe cavity. The heel upper 9 includes a heel portion 22 located on the rear side and side wings 23 located on both sides in the width direction. The two side wings 23 extend forward from both sides of the heel portion 22 in the width direction and at least partially overlap with the forefoot upper 3.

[0057] Specifically, the heel upper 9 is constructed similarly to the portion of a regular shoe upper roughly at the heel, except that it is not connected to the forefoot upper 3 to form a complete, integrated upper. Instead, it is separate from the forefoot upper 3 and cooperates with the rotating component 5 to form a rotatable and openable structure. The heel upper 9 is fixedly connected to the connecting piece 26, so it can rotate within a preset range with the rotating component 7. Furthermore, due to the presence of the ratchet pressing component 8, the heel upper 9 can also stop at any position within the preset range as the rotating component 7 stops. For example, in... Figure 1 In the state shown, the heel upper 9 rotates forward to the second position, and the heel upper 9 is in a closed state. At this time, the heel upper 9 and the forefoot upper 3 cooperate to form a shoe opening, which roughly corresponds to the user's ankle. Figure 2 In the shown state, the heel upper 9 rotates backward to the second position, the heel upper 9 is in an open state, and the opening 4 of the shoe cavity is open, making it easy for the user's foot to enter the shoe cavity. Among these, in Figure 1In the indicated state, the heel upper 9 is stopped in the second position by the limiting action of the ratchet pressing component 8. At this point, further pressing is required to release the rotating component 7 from the output end of the ratchet pressing component 8. Since the user is wearing the shoe at this time, the user's heel will prevent external force from pressing the heel upper 9, thus preventing external force from being applied to the ratchet pressing component 8. Therefore, by pulling the ratchet pressing component 8, the heel upper 9 will remain in the second position, thereby limiting the user's foot and preventing the shoe from coming off. The heel upper 9 includes a heel portion 22 on the rear side and side wings 23 extending forward in the width direction and at least partially overlapping with the forefoot upper 3. This design allows for better wrapping of the user's ankle when the shoe opening is closed, increasing the contact area and fit between the shoe opening and the ankle, making the shoe more stable and less prone to coming off during wear, while also improving the overall aesthetics and comfort of the shoe.

[0058] Reference Figure 1 and Figure 2 The ratchet pressing assembly 8 is fixedly mounted on the outer side of the sidewall of the sole 2 and is configured to accept pressing to switch its output end to extend and retract in a first direction; the output end of the ratchet pressing assembly 8 is provided with a connecting part 12 passing through the through groove 11, and the connecting part 12 is provided with limiting flanges 13 on the upper and lower sides of the connecting arm 10; the size of the limiting flanges 13 is larger than the groove width of the through groove 11, so that the limiting flanges 13 can drive the rotating member 7 to rotate around the first axis when the output end of the ratchet pressing assembly 8 extends and retracts.

[0059] Reference Figure 8 and Figure 9The ratchet pressing assembly 8 includes a housing 14, an upper ratchet member 15, a lower ratchet member 16, and an elastic member 17. The housing 14 is fixed to the sole 2, and its inner wall surface is provided with a plurality of resting positions along the circumferential direction. The resting positions include a first resting position 18 and a second resting position 19 that are adjacent and repeated along the circumferential direction. The first resting position 18 is higher than the second resting position 19 in a first direction. The lower end of the upper ratchet member 15 in the first direction and the lower ratchet member 16 form an inclined surface engagement through the ratchet teeth 20 of the two. The lower end of the upper ratchet member 15 in the first direction is provided with a plurality of resting arms 21 along the circumferential direction for abutting and engaging with the resting positions. The upper end of the upper ratchet member 15 in the first direction penetrates through the resting position. The outer shell 14 forms the output end of the ratchet pressing assembly 8; the lower ratchet 16 is fixedly connected to the outer shell 14; the elastic member 17 passes through the lower ratchet 16 along a first direction and its two ends in the first direction act on the upper ratchet 15 and the outer shell 14 respectively; the upper ratchet 15 is configured to rotate by a preset angle around a second axis extending in the first direction when pressed by engaging with the inclined surface of the lower ratchet 16, so that the stop arm 21 switches to abut against the first stop position 18 and the second stop position 19; the size of the portion of the connecting part 12 located in the through groove 11 is configured to allow the connecting part 12 to rotate relative to the through groove 11.

[0060] In this embodiment, the portion of the connecting part 12 located within the through groove 11 is cylindrical, and its outer diameter is smaller than the width of the through groove 11. Furthermore, the outer shell 14 includes an upper shell 27 and a lower shell 28 fixedly connected to each other. The docking position is located on the upper shell 27, the lower ratchet 16 is fixedly connected to the lower shell 28, and one end of the elastic member 17 abuts against the inner wall surface of the lower shell 28.

[0061] Specifically, refer to Figure 8 and Figure 9 The outer shell 14 of the ratchet pressing assembly 8 includes an upper shell 27 and a lower shell 28, which are detachably and integrally fixed by snap-fit. Internally, a chamber is formed for assembling the upper ratchet 15, lower ratchet 16, and elastic element 17. Simultaneously, the outer shell 14 can also be mounted to the side wall of the sole 2. For example, a groove is provided on the side wall, and the outer shell 14 is fixedly installed in the groove by adhesive or other means. Then, a TPU cover plate is placed over the groove to protect the internal ratchet pressing assembly 8. This arrangement facilitates the assembly of the upper ratchet 15, lower ratchet 16, and elastic element 17 into the outer shell 14. Furthermore, placing the ratchet pressing assembly 8 on the outer side wall of the sole 2 facilitates its overall installation, reduces its impact on the performance of the sole 2, and makes it easier for the ratchet pressing assembly 8 to form a transmission engagement with the rotating assembly 5.

[0062] Reference Figure 9A plurality of resting positions are provided on the inner wall of the upper housing 27 of the outer casing 14. These resting positions include a first resting position 18 and a second resting position 19, wherein the first resting position 18 is higher than the second resting position 19. Here, "the first resting position 18 is higher than the second resting position 19" means that when the outer casing 14 is mounted on the sole 2 in its normal position, in the thickness direction of the sole 2, the first resting position 18 is located above the second resting position 19. (Refer to...) Figure 9 It is understood that a boss for forming a docking position is provided protruding from the inner wall of the upper housing 27. The first docking position 18 is formed by the end of a groove-like structure opened on the boss. The second docking position 19 is adjacent to the groove of the first docking position 18 and can be regarded as a structure formed by the lower end face of the boss and a limiting wall surface connected to the end face in the circumferential direction. It is easy to understand that the first docking position 18 can limit the docking arm 21 through the groove wall of the groove-like structure. The second docking position 19 can be set as an inclined surface so that the docking arm 21 abuts against the end face and the limiting wall surface of the second docking position 19, thereby limiting the docking arm 21. To further ensure that the docking arm 21 can enter the first docking position 18, the end face of the groove opening of the first docking position 18 adjacent to the second docking position 19 can also be set as an inclined surface.

[0063] The lower end of the upper ratchet 15 is provided with ratchet teeth 20, and the lower ratchet 16 is also provided with ratchet teeth 20. The ratchet teeth 20 of the two can cooperate with each other. When the upper ratchet 15 abuts against the lower ratchet 16, the lower ratchet 16 will push the upper ratchet 15 to rotate, thereby switching the stop arm 21 of the upper ratchet 15 between the first stop position 18 and the second stop position 19. The stop arm 21 is provided on the periphery of the upper ratchet 15. The stop arm 21 protrudes from the outer peripheral surface of the upper ratchet 15. The stop arm 21 can cooperate with the stop position on the inner wall of the upper housing 27, so that the upper ratchet 15 can switch between different height positions. Since the first stop position 18 is higher than the second stop position 19, the first stop position 18 corresponds to the rotating member 7 rotating backward, with the rear heel surface in the first position. The second stop position 19 corresponds to the rotating member 7 rotating forward, with the rear heel surface in the second position. The lower ratchet 16 is fixed to the outer shell 14. Both the upper ratchet 15 and the lower ratchet 16 are provided with ratchet teeth 20 at the mating positions. Through the inclined surface cooperation between the ratchet teeth 20, the lower ratchet 16 can push the upper ratchet 15 to change its linear motion into circumferential rotation. Each time the upper ratchet 15 is pressed, the upper ratchet 15 will rotate at a preset angle, so that its stop arm 21 switches to abut against the first stop position 18 and the second stop position 19.

[0064] Meanwhile, the upper end of the upper ratchet 15 penetrates the upper housing 27, and its upper end serves as the output end of the aforementioned ratchet pressing assembly 8, having the aforementioned connecting portion 12. A limiting flange 13 is provided at the position of the connecting portion 12, arranged vertically along a first direction. The portion between the two limiting flanges 13 is cylindrical, and the outer diameter of this portion is smaller than the width of the through groove 11, while the outer diameter of the limiting flange 13 is larger than the width of the through groove 11. With this configuration, the connecting portion 12 of the upper ratchet 15 can extend into the through groove 11 from the open front end structure, allowing the connecting portion 12 to penetrate the through groove 11. Simultaneously, the two limiting flanges 13 on the connecting portion 12 are located on the upper and lower sides of the connecting arm 10, respectively. The limiting flange 13 on the upper side can pull the connecting arm 10, while the limiting flange 13 on the lower side can push the connecting arm 10. Compared to conventional ratchet pressing components 8, in this technical solution, the upper ratchet 15 itself serves as both the output and input end of the ratchet pressing component 8. Therefore, the upper ratchet 15 itself needs to be able to perform linear motion and circumferential rotation. Thus, the size of the portion of the connecting part 12 located in the through groove 11 is such that the connecting part 12 can rotate relative to the through groove 11, thereby preventing the rotation of the upper ratchet 15 from affecting the connection between the connecting part 12 and the rotating part 7.

[0065] The lower ratchet 16 is fixedly installed on the lower housing 28 of the outer casing 14. The elastic element 17 is a spring that passes through the lower ratchet 16, with its lower end abutting against the inner wall of the lower housing 28 and its upper end abutting against the upper ratchet 15. Furthermore, limiting posts can be provided on the lower housing 28 and the upper ratchet 15, and both ends of the spring can be sleeved on the limiting posts to prevent the spring from bending during the pressing process.

[0066] Embodiment 1 of this utility model provides a footwear product with a press-to-open heel. The footwear product includes a body 1, a rotating component 5, a ratchet pressing component 8, and a heel upper 9. The rotating component 5 is mounted on the body 1, and the rotating part 7 of the rotating component 5 can rotate relative to the body 1. The heel upper 9 is fixed to the rotating part 7 and can rotate relative to the body 1 with the rotating part 7, thereby opening the shoe opening to a position where it can be put on and taken off, or closing it to a position that restrains the user's ankle. The ratchet pressing component 8 is used to open and close the heel upper 9 by pressing it in a preset direction. This means that pressing the heel upper 9 in a preset direction allows it to stop between a first and a second preset position, where the first position is the open position and the second position is the closed position. The ratchet pressing component 8 uses a ratchet and tooth mechanism 20, similar to a ballpoint pen's pressing structure. Pressing allows its output end to switch between different positions and stop at that position. The challenge in combining the ratchet pressing component 8 with the rotating component 5 lies in the fact that when the user operates the heel upper 9, the force is transmitted to the rotating component 7, and then to the ratchet pressing component 8. The output end of the ratchet pressing component 8 needs to be able to both push the rotating component 7 to open and hold it in place while its position is fixed, preventing it from detaching from the output of the ratchet pressing component 8. The connection at the end; for this purpose, in this technical solution, a connecting part 12 is provided at the output end of the ratchet pressing component 8, and a limiting flange 13 is provided on the connecting part 12. At the same time, a connecting arm 10 is provided on the rotating component 7, and a through groove 11 is provided on the connecting arm 10. The connecting part 12 can pass through the through groove 11 on the connecting arm 10, and the two limiting flanges 13 provided on it are respectively located on the upper and lower sides of the connecting arm 10. Since the size of the limiting flange 13 is larger than the width of the through groove 11, the connecting part 12 will not detach from the through groove 11. The rotating component 7 can be pushed and pulled by the limiting flange 13. When the heel upper 9 is in the first position, the heel upper 9 is pulled to prevent it from tilting backward. When the heel upper 9 is in the second position, the heel upper 9 is also pulled, so that the heel upper 9 and the forefoot upper 3 cooperate to restrain the user's ankle and prevent the footwear product from loosening. Therefore, when using this footwear product, users can easily switch between the first and second positions of the heel upper 9 by pressing the heel upper 9, making the putting on and taking off process simpler.

[0067] Example 2

[0068] The difference between Example 2 and Example 1 is that the structure of the rotating component 5 is different.

[0069] Reference Figure 6 and Figure 7The first seat 24 and the second seat 25 are fixed to both sides of the rear width direction of the shoe sole 2; the rotating member 7 is a bent rod, with its two ends located outside the first seat 24 and the second seat 25, and its bending direction is inward and extends to both sides of the rear width direction of the shoe sole 2.

[0070] Specifically, refer to Figure 7 The rotating component 7 is a bent rod. After it is installed on the base 6 and the entire rotating assembly 5 is installed on the sole 2, the bending direction of the rotating component 7 faces the inside of the shoe, which can also be considered as facing the front of the shoe. The bending direction referred to here is the direction in which the inside of the rotating component 7 points when it bends. After setting the rotating component 7 as a bent rod, the first seat 24 and the second seat 25 can be set on the left and right sides of the rear of the sole 2, instead of being set at the rear end of the sole 2. In this embodiment, the installation of the first seat 24 and the second seat 25 is more convenient. The inner surfaces of the first seat 24 and the second seat 25 in the left and right directions can be directly glued to the sole 2. The outer surfaces of the first seat 24 and the second seat 25 in the left and right directions are provided with a rotating shaft extending in the left and right direction. At the same time, the inner surface of the end of the rotating component 7 is provided with a shaft hole. The rotating shaft and the shaft hole are inserted and engaged to allow the rotating component 7 to rotate relative to the base 6.

[0071] The connecting piece 26 on the rotating part 7 is arranged along the extension direction of the rotating part 7, that is, the connecting piece 26 is also bent. This type of connecting piece 26 can not only connect to the heel part 22 of the heel upper 9, but also to the side wing 23 of the heel upper 9. More connecting parts 12 improve the connection stability between the heel upper 9 and the rotating part 7, and the heel upper 9 is less prone to deformation. At the same time, during normal wear, the rotating part 7 will fix the position of the side wing 23 of the heel upper 9 to prevent the side wing 23 from opening outward, thereby improving the fit of the heel upper 9 to the user's foot.

[0072] It should be noted that due to the bent rod structure of the rotating part 7, the rotation range of the rotating part 7 is limited not only by the connecting piece 26, but also by the shape of the rotating part 7 itself. Therefore, compared with Embodiment 1, the rotation range of the heel upper 9 of the shoe provided in Embodiment 2 is smaller. However, in order to achieve the purpose of this utility model, the rotation of the heel upper 9 can still serve to allow the user's foot to extend into the shoe cavity.

[0073] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
