[0014] Technical solution ten based on technical solution eight or nine: the heel upper and the connecting plate are fixedly connected by sewing, hot melting and / or bonding.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] Technical solution 1 provides a shoe product with a heel that can be opened and closed by pressing, and the shoe product includes a body, a rotating assembly, a ratchet pressing assembly, and a heel upper. The rotating assembly is mounted on the body, and the rotating member of the rotating assembly can rotate relative to the body; the heel upper is fixed to the rotating member and can rotate relative to the body with the rotating member, so that the shoe opening of the shoe cavity can be opened to a position where it can be put on and taken off, and can also be closed to a position where the user's ankle is bound.

[0017] Among them, the ratchet pressing assembly is used to realize the pressing and rotating opening and closing of the heel upper, that is, by pressing the heel upper along a preset direction, the heel upper can be stopped between a preset first position and a second position, wherein the first position is the open position and the second position is the closed position; the ratchet pressing assembly adopts a pressing switching mechanism with ratchet and ratchet teeth, which is similar to the pressing structure of a ballpoint pen. By pressing, its output end can switch between different positions and stop at the position; the difficulty in combining the ratchet pressing assembly with the rotating assembly is that when the user operates the heel upper, the force will be transmitted to the rotating part, and then transmitted to the ratchet pressing assembly through the rotating part. The output end of the ratchet pressing assembly needs to be able to push the rotating part to open and pull the rotating part to prevent it from opening when its position is fixed. The connection with the output end of the ratchet pressing assembly will be separated; for this reason, in the technical scheme, a connecting part is provided at the output end of the ratchet pressing assembly, and a limiting flange is provided on the connecting part, and a connecting arm is provided on the rotating member, 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 respectively located on the upper and lower sides of the connecting arm, and because the size of the limiting flange is larger than the groove width of the through groove, the connecting part will not be separated from the through groove, and the rotating member can be pushed and pulled by the limiting flange, and the heel upper is pulled when the heel upper is in the first position so that it will not fall backwards, and the heel upper is also pulled when the heel upper is in the second position so that the heel upper and the forefoot upper cooperate to restrain the user's ankle, thereby preventing the footwear product from loosening.

[0018] Therefore, when using the footwear product, the user can conveniently switch the heel upper between the first position and the second position by pressing the heel upper, making the putting on and taking off process easier.

[0019] In the second technical solution, the ratchet pressing assembly includes a housing, an upper ratchet member, a lower ratchet member and an elastic member. The inner wall of the housing is provided with a plurality of parking positions, which include a first parking position and a second parking position with different heights; at the same time, a parking arm is provided on the upper ratchet member, and the parking arm abuts against the first parking position or the second parking position under the action of the elastic member, so that the upper ratchet member as the output end can achieve different extension lengths. Since the first parking position is higher than the second parking position, the first parking position corresponds to the rotation of the rotating member rotating backward, and the heel surface is in the first position, and the second parking position corresponds to the rotation of the rotating member rotating forward, and the heel surface is in the second position. The lower ratchet member is fixed to the housing, and ratchets are provided at the docking positions of the upper ratchet member and the lower ratchet member. Through the inclined surface cooperation between the ratchets, the lower ratchet member can push the upper ratchet member to convert its linear motion into circumferential rotation. Each time the upper ratchet member is pressed, the upper ratchet member will rotate a preset angle, so that its parking arm switches to abut against the first parking position and the second parking position. Compared with the conventional ratchet pressing assembly, in this technical solution, the upper ratchet part itself serves as both the output end and the input end of the ratchet pressing assembly. Therefore, the upper ratchet part itself needs to be able to perform linear motion and circumferential rotation. Therefore, the size of the portion of the connecting part located in the through groove enables the connecting part to rotate relative to the through groove, thereby preventing the rotation of the upper ratchet part from affecting the connection between the connecting part and the rotating part.

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

[0021] In technical solution four, the shell includes an upper shell and a lower shell fixed to each other, which facilitates the assembly of the upper ratchet part, the lower ratchet part and the elastic part into the shell.

[0022] In technical solution five, the heel upper includes a heel portion at the rear and side wings extending forward on both sides in the width direction and at least partially overlapping with the forefoot upper. Such a design can better wrap the user's ankle when the shoe opening is closed, thereby increasing the contact area and fit between the shoe opening and the ankle, making the footwear product more stable and not easy to loosen during wearing, while also improving the overall aesthetics and comfort of the shoe.

[0023] In technical solution six, the base adopts a first seat body and a second seat body arranged along the width direction, and the two ends of the rotating member are respectively connected to them for rotation around the first axis, and a ratchet pressing assembly is respectively arranged on the outer side of the two side walls in the width direction of the heel part of the sole to be connected to the connecting arm of the rotating member, so that the rotating member is subjected to more balanced force during the rotation process, avoiding the problem of uneven rotation or component damage caused by unilateral force, ensuring the stability and reliability of the opening and closing action of the heel upper, and improving the overall performance and service life of the footwear product.

[0024] In the seventh technical solution, a connecting piece is provided on the rotating member, and the heel upper is fixedly connected to the connecting piece; the position where the connecting piece is connected to the heel upper can be on the side of the heel upper, thereby increasing the connection area between the rotating member and the heel upper. At the same time, because the user operates the heel upper itself when opening and closing the heel upper, such a connection structure can improve the strength of the connection between the heel upper and the rotating member, and avoid the deformation of the heel upper due to the elastic force of the elastic member being too large and the upper ratchet member being unable to be pressed, resulting in the rotating member being unable to rotate. The connecting piece can also be connected to the side wings of the heel upper, and more connection parts improve the connection stability between the heel upper and the rotating member, making the heel upper less prone to deformation. At the same time, when worn normally, the rotating member will fix the position of the side wings of the heel upper to prevent the side wings from opening outward, thereby improving the wrapping of the heel upper to the user's foot.

[0025] In technical solution eight, the rotating part is a straight rod, so the first seat body and the second seat body are arranged at the rear end of the sole to prevent the rotating component from protruding from the heel of the sole and causing discomfort when wearing; the rotating part in the shape of a straight rod has a low manufacturing cost and is easy to assemble to form a rotating component.

[0026] In technical solution nine, the rotating part is a curved rod, and the first seat body and the second seat body are arranged on both sides of the rear part of the sole. The curved rod design increases the support area of ​​the rotating part, 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 10, the heel upper and the connecting piece are fixed by sewing, hot melting and / or bonding. The selection or combination of multiple fixing methods can ensure a firm and reliable connection between the heel upper and the connecting piece according to different materials, processes and design requirements, avoid separation of the upper and the connecting piece during use, and ensure the overall quality and service life of the footwear product.

[0045] Example 1

[0046] Embodiment 1 of the present invention relates to a shoe product with a heel that can be opened and closed by pressing. Figure 1 , which shows the state of the heel upper 9 of the footwear product when it is closed, and also refers to Figure 2 , which shows the state of the heel upper 9 of the footwear product when it is opened.

[0047] Reference Figure 1 and Figure 2 The footwear product mainly includes a body 1, a rotating assembly 5, a ratchet 20 pressing assembly 8 and a heel upper 9. Of course, in addition to the above components, the footwear product may also include shoelaces, decorative parts and other components, which can be arranged according to actual needs. It should be noted that the thickness direction referred to in this specification and claims is the up-down direction marked in the drawings, the width direction referred to is the left-right direction marked in the drawings, and the length direction referred to is the front-back direction marked in the drawings.

[0048] The body 1 includes a sole 2 and a forefoot upper 3, wherein 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 is of conventional construction, and can be formed by a composite outsole and a midsole, wherein the outsole can be made of a relatively 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 shock-absorbing performance. The forefoot upper 3 can be compositely fixed to the sole 2 by sewing, bonding, etc., and the material of the forefoot upper 3 can be mesh, foam, etc. Figure 1 and Figure 2 The range of the forefoot upper 3 roughly corresponds to the forefoot position and arch position of the sole 2, and part of the edge is inclined to extend to the heel position. An opening 4 is formed on the rear side of the forefoot upper 3, and a shoe cavity is formed by the forefoot upper 3 and the sole 2. 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] Obviously, the above-mentioned body 1 provides a space for accommodating the user's foot, but there is not enough limit for the user's heel, which causes the user's foot to easily escape from the shoe cavity. For this reason, the footwear product is provided with a rotating assembly 5 and a heel upper 9.

[0050] Reference Figure 3 , Figure 4 and Figure 5 The rotating assembly 5 includes a base 6 and a rotating member 7; the base 6 is fixedly connected to the rear part of the sole 2; the rotating member 7 is rotatably installed on the base 6 around 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 along its extension direction.

[0051] Reference Figure 3 In this embodiment, the base 6 includes a first seat body 24 and a second seat body 25 arranged in the width direction; the two ends of the rotating member 7 in the width direction are respectively connected to the first seat body 24 and the second seat body 25 for rotation around the first axis, and the two ends of the rotating member 7 in the width direction are provided with the connecting arms 10. A connecting piece 26 extending upward in the thickness direction is provided in 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 body 24 and the second seat body 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 body 24 and the second seat body 25.

[0053] Specifically, in this embodiment, the first seat body 24 and the second seat body 25 are both fixed at the rear end of the sole 2. This is because the rotating member 7 is set as a straight rod. In order to prevent the rotating member 7 from passing through the heel position of the sole 2, the first seat body 24 and the second seat body 25 need to be set as far back as possible. Among them, a rotating shaft protruding along the left and right directions is provided in the middle position of the inner surface of the first seat body 24 and the second seat body 25, and an axial hole recessed along the left and right directions is provided in the middle position of the two end surfaces of the rotating member 7. The rotating shafts of the first seat body 24 and the second seat body 25 can be inserted into the corresponding axial holes, so that the rotating member 7 can be rotatably connected with the first seat body 24 and the second seat body 25. At this time, the connecting line formed by the rotating shafts set in the first seat body 24 and the second seat body 25 is the above-mentioned first axis. The base 6 adopts a first seat body 24 and a second seat body 25 arranged along the width direction, and the two ends of the rotating member 7 are respectively connected to them for rotation around the first axis, and ratchet teeth 20 are respectively arranged on the outer sides of the width direction of the two side walls of the heel part 22 of the sole 2 to press the assembly 8 to connect with the connecting arm 10 of the rotating member 7, so that the rotating member 7 is subjected to more balanced force during the rotation process, avoiding the problem of uneven rotation or component damage caused by unilateral force, ensuring the stability and reliability of the opening and closing action of the heel upper 9, and improving the overall performance and service life of the footwear product. The rotating member 7 is a straight rod, so the first seat body 24 and the second seat body 25 are arranged at the rear end of the sole 2 to avoid the rotating assembly 5 protruding from the heel position of the sole 2, which causes discomfort when wearing; the rotating member 7 in the form of a straight rod has low manufacturing cost and is easy to assemble to form the rotating assembly 5.

[0054] The connecting piece 26 is arranged on the rotating member 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 a structural stability that is not easily deformed, such as synthetic leather. The connecting piece 26 can be fixed on the rotating member 7 by bonding, hot melting, etc. For example, when the rotating member 7 is made of plastic, it can be fixed by hot melting. The connecting piece 26 is arranged on the rotating member 7, and the heel upper 9 is fixed on the connecting piece 26; the position where the connecting piece 26 is connected to the heel upper 9 can be on the side of the heel upper 9, thereby increasing the connection area between the rotating member 7 and the heel upper 9. At the same time, since the user operates the heel upper 9 itself when operating to open and close the heel upper 9, such a connection structure can improve the strength of the connection between the heel upper 9 and the rotating member 7, and avoid the upper ratchet 20 15 being unable to be pressed when the heel upper 9 is toggled because the elastic force of the elastic member 17 is too large, resulting in the rotating member 7 being unable to rotate and causing the heel upper 9 to deform. Among them, the connecting piece 26 can also be connected to the side wings 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 likely to be deformed. At the same time, during normal wear, the rotating part 7 will fix the position of the side wings 23 of the heel upper 9 to prevent the side wings 23 from opening outward, thereby improving the wrapping of the heel upper 9 on the user's foot.

[0055] The above-mentioned connecting arms 10 are provided at the left and right ends of the rotating member 7. The connecting arms 10 extend roughly along the length direction of the footwear product, and the connecting arms 10 are located on the front side of the first seat body 24 and the second seat body 25. It is easy to know that since the connecting arms 10 need to cooperate with the external ratchet 20 pressing assembly 8, the connecting arms 10 need to be provided on the outside of the rotating member 7 and cannot interfere with the first seat body 24 and the second seat body 25 of the base 6. To this end, in this embodiment, a forming portion extending outward and in an arc shape can be provided at the left and right ends of the rotating member 7. The forming portion can rotate around the first axis along the outer peripheral surface of the first seat body 24 and the second seat body 25, and the connecting arm 10 is provided on the side surface of the forming portion away from the first seat body 24 and the second seat body 25. Refer to Figure 5 The connecting arm 10 is provided with a through slot 11 which passes through in the up-down direction. The front end of the through slot 11 can be set to an open structure to facilitate the matching 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 at the first and second preset positions relative to the base 6 along with the rotating member 7, and cooperate with the forefoot upper 3 to form a shoe opening together with the shoe cavity when stopped. The heel upper 9 includes a heel portion 22 at the rear side and side wings 23 at both sides in the width direction, and the two side wings 23 extend forward from both sides in the width direction of the heel portion 22 and at least partially overlap with the forefoot upper 3.

[0057] Specifically, the structure of the heel upper 9 is similar to the part of the upper of a conventional shoe that is roughly at the heel position, except that the heel upper 9 is not connected to the forefoot upper 3 to form a complete, integrated upper, but is separated from the forefoot upper 3 and cooperates with the rotating component 5 to form a rotatable opening and closing structure. The heel upper 9 is fixedly connected to the connecting piece 26, so the heel upper 9 can rotate with the rotating member 7 within a preset range, and due to the presence of the ratchet 20 pressing the component 8, the heel upper 9 can also stop at any position within the preset range as the rotating member 7 stops. For example, 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 cooperates with the forefoot upper 3 to form a shoe opening, which roughly corresponds to the user's ankle; Figure 2 In the state shown, 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, which is convenient for the user's foot to enter the shoe cavity. Figure 1In the state shown, the heel upper 9 is stopped at the second position by the limiting action of the ratchet 20 pressing assembly 8. At this time, it needs to be pressed again to make the output end of the ratchet 20 pressing assembly 8 release the rotating member 7. At this time, the user is just wearing shoes, and the heel of the user's foot will prevent the external force from pressing the heel upper 9, thereby preventing the outside from applying force to the ratchet 20 pressing assembly 8. Therefore, at this time, through the pulling of the ratchet 20 pressing assembly 8, the heel upper 9 will remain in the second position, thereby playing a limiting role for the user's foot and preventing the shoe product from loosening. The heel upper 9 includes a rear heel portion 22 and side wings 23 extending forward on both sides in the width direction and at least partially overlapping with the forefoot upper 3. Such a design can better wrap the user's ankle when the shoe mouth is closed, increase the contact area and fit between the shoe mouth and the ankle, make the shoe product more stable during wearing and not easy to loosen, and also improve the overall aesthetics and comfort of the shoe.

[0058] Reference Figure 1 and Figure 2 The ratchet 20 pressing assembly 8 is fixedly mounted on the outer side of the side wall of the sole 2, and is configured to be suitable for receiving pressure to switch its output end to extend and retract along the first direction; the output end of the ratchet 20 pressing assembly 8 is provided with a connecting portion 12 passing through the through groove 11, and the connecting portion 12 is provided with limiting flanges 13 on the upper and lower sides of the connecting arm 10; the size of the limiting flange 13 is larger than the groove width of the through groove 11, so that the rotating member 7 can be driven to rotate around the first axis through the limiting flange 13 when the output end of the ratchet 20 pressing assembly 8 extends and retracts.

[0059] Reference Figure 8 and Fig. 9The ratchet 20 pressing assembly 8 includes a shell 14, an upper ratchet 20 piece 15, a lower ratchet 20 piece 16 and an elastic piece 17; the shell 14 is fixed to the sole 2, and a plurality of stop positions are arranged on its inner wall surface along the circumferential direction, and the stop positions include a first stop position 18 and a second stop position 19 which are adjacent and repeatedly arranged along the circumferential direction, and the first stop position 18 is higher than the second stop position 19 in the first direction; the lower end of the upper ratchet 20 piece 15 in the first direction forms an inclined surface with the lower ratchet 20 piece 16 through the ratchet 20 they both have, and the lower end of the first direction is circumferentially provided with a plurality of stop arms 21 for abutting and cooperating with the stop positions, and the upper end of the upper ratchet 20 piece 15 in the first direction penetrates the The shell 14 forms the output end of the ratchet 20 pressing assembly 8; the lower ratchet 20 piece 16 is fixedly connected to the shell 14; the elastic member 17 penetrates the lower ratchet 20 piece 16 along the first direction and its two ends in the first direction act on the upper ratchet 20 piece 15 and the shell 14 respectively; the upper ratchet 20 piece 15 is configured to rotate a preset angle around a second axis extending in the first direction by cooperating with the inclined surface of the lower ratchet 20 piece 16 when pressed, so that the parking arm 21 switches to abut the first parking position 18 and the second parking position 19; the size of the portion of the connecting portion 12 located in the through slot 11 is configured to be suitable for the connecting portion 12 to rotate relative to the through slot 11.

[0060] In this embodiment, the portion of the connecting portion 12 located in the through slot 11 is cylindrical, and its outer diameter is smaller than the slot width of the through slot 11. In addition, the housing 14 includes an upper shell 27 and a lower shell 28 fixed to each other, the parking position is provided at the upper shell 27, the lower ratchet 20 member 16 is fixed 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 Fig. 9 The shell 14 of the ratchet 20 pressing assembly 8 includes an upper shell 27 and a lower shell 28, which can be detachably fixed as a whole by a snap-on method, and a chamber for assembling the upper ratchet 20 piece 15, the lower ratchet 20 piece 16 and the elastic member 17 is formed inside. At the same time, the shell 14 can also be installed on the side wall of the sole 2, for example, a groove is set on the side wall, and the shell 14 is fixedly installed in the groove by bonding or other means, and then the TPU cover plate is covered outside the groove to protect the ratchet 20 pressing assembly 8 inside. Such a setting makes it convenient to assemble the upper ratchet 20 piece 15, the lower ratchet 20 piece 16 and the elastic member 17 into the shell 14. In addition, the ratchet 20 pressing assembly 8 is arranged outside the side wall of the sole 2, which can facilitate the overall installation of the ratchet 20 pressing assembly 8, reduce the influence of the ratchet 20 pressing assembly 8 on the performance of the sole 2, and also make it more convenient for the ratchet 20 pressing assembly 8 to form a transmission match with the rotating assembly 5.

[0062] Reference Fig. 9 , a plurality of stop positions are arranged on the inner wall of the upper shell 27 of the outer shell 14, and the stop positions include a first stop position 18 and a second stop position 19, wherein the first stop position 18 is higher than the second stop position 19. Here, the first stop position 18 is higher than the second stop position 19 means that when the outer shell 14 is installed on the sole 2 in a normal posture, in the thickness direction of the sole 2, the first stop position 18 is located above the second stop position 19. Fig. 9 It can be seen that a boss for forming a parking position is protruded from the inner wall of the upper shell 27, and the first parking position 18 is formed by the end of the groove-like structure opened on the boss. The second parking position 19 is adjacent to the slide groove of the first parking position 18, and can be regarded as a structure formed by the end face of the lower end of the boss and a limiting wall connected to the end face in the circumferential direction. It is easy to understand that the first parking position 18 can limit the parking arm 21 through the groove wall of the groove-like structure, and the second parking position 19 can be set as an inclined surface, so that the parking arm 21 abuts against the end face and the limiting wall of the second parking position 19, thereby limiting the parking arm 21. In order to further ensure that the parking arm 21 can enter the first parking position 18, the notch position of the groove-like structure of the first parking position 18 and the end face adjacent to the second parking position 19 can also be set as an inclined surface.

[0063] The lower end of the upper ratchet 20 piece 15 is provided with a ratchet 20, and the lower ratchet 20 piece 16 is also provided with a ratchet 20, and the ratchet 20 of the two pieces can cooperate with each other. When the upper ratchet 20 piece 15 abuts against the lower ratchet 20 piece 16, the lower ratchet 20 piece 16 will push the upper ratchet 20 piece 15 to rotate, so that the parking arm 21 of the upper ratchet 20 piece 15 switches between the first parking position 18 and the second parking position 19. The circumferential side of the upper ratchet 20 piece 15 is provided with a parking arm 21, which protrudes from the outer circumferential surface of the upper ratchet 20 piece 15, and the parking arm 21 can cooperate with the parking position on the inner wall of the upper shell 27, so that the upper ratchet 20 piece 15 switches 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 rotation of the rotating member 7 backward, and the heel surface is in the first position, and the second stop position 19 corresponds to the rotation of the rotating member 7 forward, and the heel surface is in the second position. The lower ratchet 20 piece 16 is fixed to the housing 14, and ratchets 20 are provided at the docking positions of the upper ratchet 20 piece 15 and the lower ratchet 20 piece 16. Through the inclined surface cooperation between the ratchet teeth 20, the lower ratchet 20 piece 16 can push the upper ratchet 20 piece 15 to convert its linear motion into circumferential rotation. Each time the upper ratchet 20 piece 15 is pressed, the upper ratchet 20 piece 15 will rotate a preset angle, so that its parking arm 21 switches to abut the first stop position 18 and the second stop position 19.

[0064] Meanwhile, the upper end of the upper ratchet 20 piece 15 penetrates the upper shell 27, and the upper end thereof serves as the output end of the ratchet 20 pressing assembly 8, and has the connection portion 12. A limiting flange 13 arranged up and down along the first direction is provided at the position of the connection portion 12, and the portion between the two limiting flanges 13 is cylindrical, and the outer diameter of the portion is smaller than the slot width of the through slot 11, and the outer diameter of the limiting flange 13 is larger than the slot width of the through slot 11. In this way, the connection portion 12 of the upper ratchet 20 piece 15 can extend into the through slot 11 from the front end opening structure of the through slot 11, so that the connection portion 12 penetrates the through slot 11, and the two limiting flanges 13 on the connection portion 12 are respectively located on the upper side and the lower side of the connecting arm 10, and the limiting flange 13 located on the upper side can pull the connecting arm 10, while the limiting flange 13 located on the lower side can push the connecting arm 10. Compared to the conventional ratchet 20 pressing assembly 8, in this technical solution, the upper ratchet 20 piece 15 itself serves as both the output end and the input end of the ratchet 20 pressing assembly 8. Therefore, the upper ratchet 20 piece 15 itself needs to be able to perform linear motion and circumferential rotation. Therefore, the size of the portion of the connecting portion 12 located in the through groove 11 is such that the connecting portion 12 can rotate relative to the through groove 11, thereby preventing the rotation of the upper ratchet 20 piece 15 from affecting the connection between the connecting portion 12 and the rotating member 7.

[0065] The lower ratchet 20 piece 16 is fixedly mounted on the lower shell 28 of the housing 14. The elastic member 17 is a spring, which passes through the lower ratchet 20 piece 16, and its lower end abuts against the inner wall of the lower shell 28, and its upper end abuts against the upper ratchet 20 piece 15. Further, a limit column can be provided on the lower shell 28 and the upper ratchet 20 piece 15, and both ends of the spring are sleeved on the limit column to prevent the spring from bending during the pressing process.

[0066] Embodiment 1 of the present invention provides a shoe product with a heel that can be opened and closed by pressing, and the shoe product comprises a body 1, a rotating assembly 5, a ratchet 20 pressing assembly 8, and a heel upper 9. The rotating assembly 5 is mounted on the body 1, and the rotating member 7 of the rotating assembly 5 can rotate relative to the body 1; the heel upper 9 is fixed to the rotating member 7, and can rotate relative to the body 1 with the rotating member 7, so that the shoe opening of the shoe cavity can be opened to a position where the shoe can be put on and taken off, and can also be closed to a position where the user's ankle is bound. Among them, the ratchet 20 pressing component 8 is used to realize the pressing and rotating opening and closing of the heel upper 9, that is, by pressing the heel upper 9 along a preset direction, the heel upper 9 can be docked between a preset first position and a second position, wherein the first position is the open position and the second position is the closed position; the ratchet 20 pressing component 8 adopts a pressing switching mechanism coordinated with the ratchet wheel and ratchet teeth 20. This component is similar to the pressing structure of a ballpoint pen. By pressing, its output end can switch between different positions and dock at this position; the difficulty in combining the ratchet 20 pressing component 8 with the rotating component 5 is that when the user operates the heel upper 9, the force will be transmitted to the rotating part 7, and then transmitted to the ratchet 20 pressing component 8 through the rotating part 7. The output end of the ratchet 20 pressing component 8 needs to be able to push the rotating part 7 to open and pull the rotating part 7 so that it will not separate from the ratchet 20 pressing component when its position is fixed. The output end of the component 8 is connected; for this purpose, in the technical scheme, a connecting portion 12 is provided at the output end of the ratchet 20 pressing assembly 8, and a limiting flange 13 is provided on the connecting portion 12, and a connecting arm 10 is provided on the rotating member 7, and a through groove 11 is provided on the connecting arm 10; the connecting portion 12 can penetrate the through groove 11 on the connecting arm 10, and the two limiting flanges 13 provided thereon are respectively located on the upper and lower sides of the connecting arm 10, and because the size of the limiting flange 13 is larger than the groove width of the through groove 11, the connecting portion 12 will not be separated from the through groove 11, and the rotating member 7 can be pushed and pulled by the limiting flange 13, and the heel upper 9 is pulled when the heel upper 9 is in the first position so that it will not fall backwards, and the heel upper 9 is also pulled when the heel upper 9 is in the second position, so that the heel upper 9 and the forefoot upper 3 cooperate to restrain the user's ankle, thereby preventing the footwear product from loosening. Therefore, when using the footwear product, the user can conveniently press the heel upper 9 to switch the heel upper 9 between the first position and the second position, making the putting on and taking off process easier.

[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 body 24 and the second seat body 25 are fixed on both sides of the width direction of the rear part of the sole 2; the rotating member 7 is a bent rod, whose two ends are located on the outside of the first seat body 24 and the second seat body 25, and its bending direction is inward and extends to both sides of the width direction of the rear part of the sole 2.

[0070] Specifically, refer to Figure 7 The rotating member 7 is a curved rod. After the rotating member 7 is installed on the base 6 and the entire rotating assembly 5 is installed on the sole 2, the bending direction of the rotating member 7 is toward the inner side of the shoe, which can also be regarded as toward the front side of the shoe. The bending direction referred to here refers to the direction in which the inner side of the rotating member 7 points when it is bent. After the rotating member 7 is set as a curved rod, the first seat body 24 and the second seat body 25 can be set on the left and right sides of the rear part 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 body 24 and the second seat body 25 is more convenient. The inner side surfaces of the first seat body 24 and the second seat body 25 in the left and right directions can be directly bonded to the sole 2. The outer side surfaces of the first seat body 24 and the second seat body 25 in the left and right directions are provided with a rotating shaft extending in the left and right directions. At the same time, an axial hole is provided on the inner side surface of the end of the rotating member 7. The rotating shaft and the axial hole are plugged and matched to enable the rotating member 7 to rotate relative to the base 6.

[0071] The connecting piece 26 on the rotating member 7 is arranged along the extension direction of the rotating member 7, that is, the connecting piece 26 is also bent. The connecting piece 26 of this shape can not only be connected to the heel portion 22 of the heel upper 9, but also be connected to the side wings 23 of the heel upper 9. More connecting parts 12 improve the connection stability between the heel upper 9 and the rotating member 7, and the heel upper 9 is less likely to be deformed. At the same time, during normal wear, the rotating member 7 will fix the position of the side wings 23 of the heel upper 9 to prevent the side wings 23 from opening outward, thereby improving the wrapping of the heel upper 9 on the user's foot.

[0072] It should be noted that due to the bent rod structure of the rotating member 7, the rotation range of the rotating member 7 is not only limited by the connecting plate 26, but also by the shape of the rotating member 7 itself. Therefore, compared with the first embodiment, the rotation range of the heel upper 9 of the shoe provided in the second embodiment is smaller. However, in order to achieve the purpose of the present invention, the rotation of the heel upper 9 can still play a role in allowing the user's foot to extend into the shoe cavity.

[0073] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
