Description

Technical Field

[0001] The utility model relates to the technical field of height adjustment, in particular to a height adjustment device and a footwear article. Background Art

[0002] At present, height adjustment devices are required in many fields. For example, in the case of stools, tables or racks with multiple legs, especially for footwear articles that need to increase the height of the insole relative to the ground, that is, have a height increasing function. Taking current shoes as an example, their height increasing function is only achieved by relying on the insole or the hidden thickening of the sole. Users cannot independently adjust the height increase, let alone conveniently adjust the specific height value according to actual needs and maintain the corresponding height value during use. Therefore, the existing height adjustment devices cannot meet the requirements of dynamic height adjustment, especially the requirement of the footwear article with a height increasing function to adjust the height according to the occasion and the real-time needs of the user, and the requirement of being able to adjust quickly and reliably maintain the height value unchanged.

[0003] Therefore, there is an urgent need for a height adjustment device and a footwear article that can quickly and reliably achieve height adjustment. Summary of the Utility Model

[0081] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, where the same or similar reference numerals represent the same or similar components or components with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation on the present utility model.

[0082] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "length", "width", "horizontal", "vertical", "top", "bottom", "inner", "outer", etc., which indicate the orientation or positional relationship used in the description of the present utility model, are all based on the orientation or positional relationship shown in the accompanying drawings. They are intended to facilitate the description of the present utility model and simplify the description, and should not be construed as a limitation on the device or component that must have a specific orientation or specific positional relationship.

[0083] In addition, the terms "first" and "second" are only used for the purpose of distinguishing descriptions, without the connotation of relative importance, and are not intended to indicate or imply the number of technical features. Therefore, the features defined by "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise clearly defined.

[0084] Unless otherwise clearly specified, terms such as "connection" and "fixation" in the present utility model should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral molding; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0085] The height adjustment device of the present utility model and the footwear article including the same will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0086] Reference Figures 1 to 24, as an object of the present utility model, a height adjustment device 10 is provided, which includes a main driving member 1, a driven member 2, a lifting member 3, a housing 4, and a non-return disk 5. The main driving member 1 is rotatably disposed on the housing 4. The driven member 2 is supported by the housing 4 and can rotate relative to the housing 4. The main driving member 1 and the driven member 2 are operatively connected and separated. When the driven member 2 is configured to rotate in the first direction, the lifting member 3 moves upward, and when the lifting member 3 moves downward, the driven member 2 rotates in the second direction, where the first direction and the second direction are opposite. In the present utility model, the first direction is the clockwise direction, and the second direction is the counterclockwise direction. The main driving member 1 is connected to the non-return disk 5. The non-return disk 5 includes one or more first non-return members, and the housing 4 is provided with one or more second non-return members. The second non-return members cooperate with the first non-return members to form a non-return assembly. When the main driving member 1 and the driven member 2 are in a connected state, when the main driving member 1 receives a driving force in the first direction, the non-return assembly allows the main driving member 1 to drive the driven member 2 to rotate in the first direction and then drive the lifting member 3 to rise; and when the lifting member 3 is subjected to pressure, the non-return assembly prevents the driven member 2 from rotating in the second direction, and the position of the lifting member 3 is maintained; when the main driving member 1 and the driven member 2 are in a separated state, the resistance to the rotation of the driven member 2 in the second direction is released. When the lifting member 3 is subjected to pressure, the pressure causes the lifting member 3 to move downward while driving the driven member 2 to rotate in the second direction.

[0087] Therefore, for the height adjustment device provided by the present utility model, the main driving member 1 is operatively connected and separated from the driven member 2. Thus, when the main driving member 1 and the driven member 2 are in a connected state, the upward movement of the lifting member 3 can be realized by driving the driven member 2, and the non-return assembly formed by the cooperation of the non-return disk 5 connected to the main driving member 1 and the non-return members of the housing 4 is used to prevent the driven member 2 from rotating in the second direction to maintain the upward position of the lifting member 3. Therefore, the height of the lifting member 3 can be conveniently adjusted; and when the main driving member 1 and the driven member 2 are in a separated state, since the driven member 2 is no longer blocked by the non-return assembly, the lifting member that moves downward under pressure can drive the driven member 2 to rotate in the second direction at the same time, in preparation for the next upward movement of the lifting member.

[0088] Please refer to Figure 1 , Figure 2 , Figures 15 to 18, preferably, the height adjusting device further includes a transmission clutch member 6, and the main driving member 1 and the driven member 2 are operably connected and separated through the transmission clutch member 6, so that the operable connection and separation of the main driving member 1 and the driven member 2 can be conveniently realized. Preferably, the transmission clutch member 6 is configured to be able to move up and down axially relative to the main driving member, the anti-reverse disk or the driven member, so as to realize the operable connection and separation of the main driving member 1 and the driven member 2. For example, when the transmission clutch member 6 rises, the main driving member 1 and the driven member 2 are separated; when the transmission clutch member 6 descends, the main driving member 1 and the driven member 2 are connected. Specifically, engaging teeth and driven teeth can be respectively provided on the transmission clutch member 6 and the driven member 2, and the engagement and separation of the two are used to realize the connection and separation of the main driving member 1 and the driven member 2. The control of the lifting of the transmission clutch member can also be directly realized by applying a pulling force, or can be realized by the conversion of the motion form, such as the conversion of the rotational motion into the form of the lifting motion.

[0089] Further preferably, please refer to Figures 15 to 18 , the transmission clutch member 6 is connected to the main driving member 1 through a spiral structure, and the spiral transmission uses the engagement of the screw rod and the nut to realize the conversion of the rotational motion into the linear motion. In the spiral transmission, the thread surfaces of the screw rod and the nut are screwed together, so that the rotational motion is converted into the axial motion, that is, the linear motion, through the interaction of the screw pair. This conversion mechanism enables the spiral transmission to effectively convert the rotational energy into the linear motion, so as to realize functions such as lifting and propulsion in various mechanical devices. By restricting the rotational motion of the transmission clutch member 6, the rotational motion of the rotating column 14 is converted into the lifting motion of the transmission clutch member 6.

[0090] In order to restrict the rotational motion of the transmission clutch member 6, the transmission clutch member 6 is fixedly connected to the anti-reverse disk 5 in the circumferential direction, so that the transmission clutch member 6 cannot rotate independently relative to the anti-reverse disk 5, and the synchronous rotation or synchronous stillness of the transmission clutch member 6 and the anti-reverse disk 5 can be used to restrict the independent rotational motion of the transmission clutch member 6, so as to realize the spiral transmission between the main driving member 1 and the transmission clutch member 6.

[0091] Please refer to Figures 19 to 24 , preferably, the main driving member 1 and the anti-reverse disk 5 are rotatably connected within a limited range. Specifically, the rotatable connection within a limited range means that the main driving member 1 is linked with the anti-reverse disk 5 after rotating a certain angle relative to the anti-reverse disk 5. In this way, during the rotation of the main driving member 1 relative to the anti-reverse disk 5 within a limited range, that is, when the driving block 13 moves from Figure 19 the position to Figure 22At the shown position, the main driving member 1 drives the rotating column 14 to rotate clockwise. At this time, the anti-reverse disk 5 remains stationary. Since the transmission clutch member 6 is fixedly connected to the anti-reverse disk 5 in the circumferential direction, the transmission clutch member 6 cannot rotate in the circumferential direction either. According to the principle of screw transmission, the screw structure converts the clockwise rotational movement of the rotating column 14 into a downward movement of the transmission clutch member 6, so that the transmission clutch member 6 is connected to the driven member 2, and thus the connection between the main driving member 1 and the driven member 2 is realized. Similarly, if the main driving member 1 rotates counterclockwise by a certain angle relative to the anti-reverse disk 5, that is, the driving block 13 rotates from Figure 22 to the position of Figure 19 shown position, then the main driving member 1 drives the rotating column 14 to rotate counterclockwise. According to the principle of screw transmission, the screw structure converts the counterclockwise rotational movement of the rotating column 14 into an upward movement of the transmission clutch member 6, so that the transmission clutch member 6 is separated from the driven member 2, and thus the separation between the main driving member 1 and the driven member 2 is realized. Therefore, the rotation of the main driving member 1 relative to the anti-reverse disk 5 within a limited range causes the lifting and lowering movement of the transmission clutch member, and further realizes the connection and separation of the main driving member 1 and the driven member 2. In other preferred embodiments, the rotation angle range, as well as the corresponding form of the rotation direction and the lifting and lowering movement, can be adjusted according to actual needs. Among them, the corresponding form of the rotation direction and the lifting and lowering movement is related to the anti-reverse direction of the anti-reverse assembly in the height adjustment device. The rotation direction for realizing the separation of the transmission clutch member and the driven member is the anti-reverse direction. The connection structure between the transmission clutch member 6 and the driven member 2 can be a tooth engagement structure.

[0092] Please refer to Figure 1 , Figure 2 , Figure 8 and Figure 17 . Preferably, the housing 4 includes a sleeve 41 and a chassis 42. The main driving member 1 is rotatably arranged on the sleeve 41, so that the sleeve 41 can provide support for the rotation of the main driving member 1. The second anti-reverse member is arranged in the sleeve 41 and can cooperate with the first anti-reverse member of the anti-reverse disk 5 to prevent the anti-reverse disk from reversing in the second direction, thereby preventing the transmission clutch member 6 and the driven member 2 from reversing in the second direction.

[0093] Refer to Figure 13 . The height adjustment device further includes a rotation prevention member 7 for preventing the lifting member 3 from rotating and allowing the lifting member 3 to perform lifting and lowering movements. Preferably, the rotation prevention member 7 is fixedly arranged on the chassis 42.

[0094] Embodiment 1

[0095] Please refer to Figures 3 to 24 . For the above description, the following provides a more specific and detailed description of the present invention with a specific embodiment to more clearly understand the inventive concept of the present invention. In this embodiment, the main driving member 1 can be configured as a main rotating disk, such asFigure 3 and Figure 4 As shown in Figure 4 , the main rotating disk includes a disk portion 11 and an annular disk portion 12 vertically extending along the edge of the disk portion 11. The annular disk portion 12 is provided with an operable portion 121 for applying an external force to the main rotating disk. A plurality of driving blocks 13 and a rotating column 14 are provided on the inner surface of the disk portion 11. A first thread 15 is provided on the outer circumference of the rotating column 14, which is equivalent to a screw; correspondingly, as Figure 11 and 12 shown, the transmission clutch member 6 can be configured as a lifting engagement gear disk. The lifting engagement gear disk includes a gear disk main body 61 and a gear disk through hole 62 opened inside the gear disk main body 61. A second thread 63 helically connected to the first thread 15 is provided on the hole surface of the gear disk through hole 62, which is equivalent to a nut. Thus, as Figures 19 to 24 shown, during the process of rotating the main rotating disk in the first direction (clockwise direction) so that it rotates by a certain angle relative to the anti-reverse disk, the main rotating disk can drive the lifting engagement gear disk connected by screw to descend. Thus, the main rotating disk is operably connected to the driven member by means of the lifting engagement gear disk, and further drives the main rotating disk to rotate in the first direction. The main rotating disk drives the driven member to rotate and then drives the lifting member 3 to move upward; during the process of rotating the main rotating disk in the second direction (counterclockwise direction) so that it rotates by a certain angle relative to the anti-reverse disk, the main rotating disk can drive the lifting engagement gear disk connected by screw to ascend. Thus, the main rotating disk is operably separated from the driven member by means of the lifting engagement gear disk. At this time, when the lifting member 3 moves downward under pressure, since the driven member and the lifting member 3 are also screw-driven, the downward movement of the lifting member drives the driven member to rotate in the second direction (counterclockwise direction). Therefore, by setting the lifting engagement gear disk, the purpose of indirectly operably connecting and separating the main rotating disk and the driven member is achieved. It can not only drive the driven member to drive the lifting member 3 to move upward when the two are in a connected state, and the driven member is subject to the resistance of the anti-reverse disk to maintain the height of the lifting member 3, but also when the two are in a separated state and the driven member is released from the restraint of the resistance of the anti-reverse disk, the lifting member 3 can drive the driven member to rotate in the second direction while descending under the action of pressure, so that the lifting member 3 descends to a certain height or returns to the initial low position for being driven to move upward again and rise again.

[0096] Furthermore, please refer to Figure 11 and Figure 12 , a mating tooth 64 is provided on the first tooth disk end surface of the gear disk main body 61 of the lifting engagement gear disk; correspondingly, referring to Figure 5, the driven member 2 is configured as a rotating wheel, and the rotating wheel is disposed in the sleeve 41. The rotating wheel includes a hub 21, and a driven tooth 22 is provided at the top of the hub 21. The engaging tooth 64 is detachably engaged with the driven tooth 22. Therefore, when the engaging tooth 64 is engaged with the driven tooth 22, the engaging tooth 64 can drive the driven tooth 22 to rotate and the main driving member 1 is connected to the driven member 2, so that the main driving member 1 rotating in the first direction can drive the driven member 2 to rotate in the first direction, thereby driving the lifting member 3 to move upward; when the engaging tooth 64 is separated from the driven tooth 22, the engaging tooth 64 cannot drive the driven tooth 22 to rotate and the transmission clutch member 6 is separated from the driven member 2, so that the driven member 2 no longer blocked by the anti-reverse disk 5 can rotate in the second direction as the lifting member 3 descends.

[0097] Please refer to Figures 5 to 7 , specifically, the hub 21 is provided with a threaded through hole 23 having a third thread 24. The lifting member 3 includes a lifting rod 31, and a fourth thread 311 screwed with the third thread 24 is provided on the lifting rod 31. The fourth thread 311 is preferably provided at the bottom of the lifting rod 31, and can also be provided at other parts of the lifting rod 31. In this way, through the screw drive between the third thread 24 and the fourth thread 311, the lifting height of the lifting rod 31 can be accurately driven by the rotating wheel, and the rotating wheel can be synchronously rotated while the lifting rod 31 descends to a certain height or even resets, avoiding interference between the two.

[0098] Please refer to Figure 7 and Figure 13 , further preferably, the lifting rod 31 is provided with a rotation stopping hole 312 penetrating along the central axis of the rod, and the rotation stopping hole 312 is set as a multi-faceted column hole; the rotation stopping member 7 includes a rotation stopping rod 71, and the rotation stopping rod 71 is disposed on the chassis 42. In this embodiment, the rotation stopping rod 71 and the chassis 42 are integrally formed. The rotation stopping rod 71 is configured as a multi-faceted prism, and the multi-faceted prism-shaped rotation stopping rod 71 is inserted into the multi-faceted column hole 312. More preferably, in this embodiment, the rotation stopping rod 71 is set as a four-straight-face prism, and the rotation stopping hole 312 is set as a four-straight-face column hole. In addition, in other preferred embodiments, the surfaces of the rotation stopping rod 71 and the rotation stopping hole 312 can also be arc surfaces or curved surfaces, as long as the overall outer surface of the rotation stopping rod 71 and the shape of the rotation stopping hole 312 are matched, and the overall inner surface is non-cylindrical, and the two will be linked in the circumferential rotation direction. This design enables the rotation stopping rod 71 and the rotation stopping hole 312 to be in surface-to-surface contact and cooperation to prevent the lifting rod 31 from rotating and allow it to perform lifting motion. Therefore, the limiting effect of the rotation stopping rod 71 on the rotation stopping hole 312 in the circumferential direction enables the relative rotational motion between the rotating wheel and the lifting rod 31 to generate the axial motion of the lifting rod 31 under the action of the axial component force, thereby achieving the purpose of adjusting the lifting height of the lifting rod 31.

[0099] Preferably, the check disk 5 is an outer ratchet ring and an internal ratchet 413 is provided on the sleeve 41. Refer to Figures 9 to 10 , the check disk 5 is configured as an outer ratchet ring. The outer ratchet ring includes a ring body 51 and a ring hole 52 surrounded by the ring body 51. A plurality of pawls 54 are provided on the outer ring surface of the ring body 51. Preferably, each pawl 54 is integrally formed with the ring body 51. Among them, the pawl 54 is the first check member. The pawl 54 includes a pawl arm 541 and at least one pawl tooth 542 provided at the free end of the pawl arm 541. The pawl tooth 542 can be engaged with the internal ratchet 413 on the sleeve 41. The second check member is the ratchet tooth 4131 of the internal ratchet 413. Please refer to Figure 8 , the sleeve 41 includes a cylindrical peripheral shell 411 and a partition 412. The cylindrical peripheral shell 411 encloses to form an inner cavity 4121. The partition 412 is horizontally arranged in the inner cavity 4121 and divides it into an upper chamber and a lower chamber. An internal ratchet 413 is provided on the inner peripheral wall of the upper chamber above the partition 412, and the outer ratchet ring is also located above the partition 412; the rotating wheel 2 is arranged in the lower chamber. The partition 412 spatially isolates the check assembly from the rotating wheel to avoid mutual interference between the two. Preferably, the ratchet tooth 4131 is configured such that its first tooth surface slidably cooperates with the pawl tooth 542, so that the pawl tooth 542 can relatively pass through the first tooth surface of each ratchet tooth 4131. Furthermore, when the main rotating disk rotates in the first direction, its driving pawl 54 rotates in the first direction. Then, the check disk 5 drives the lifting engagement tooth disk and the rotating wheel to rotate in the first direction together so that the lifting rod 31 moves upward. And, the second tooth surface of the ratchet tooth 4131 opposite to each first tooth surface is configured to abut against the pawl tooth 542 and prevent the pawl tooth 542 from moving away from the second tooth surface, thereby preventing the pawl 54 from rotating in the second direction. Then, the check disk 5 prevents the connected lifting engagement tooth disk and the rotating wheel from rotating in the second direction, thus ensuring that the lifting rod 31 connected to the rotating wheel can rise to a certain position and remain unchanged. Regarding the specific setting manner of the pawl tooth 542 and the ratchet tooth 4131, it is known to those skilled in the art and can refer to CN116509108A and CN108791997A, which will not be elaborated here. In other preferred embodiments, the check disk 5 can be configured as an outer ratchet and an internal pawl ring is provided on the sleeve 41. The above-described check assembly has a compact and reliable structure.

[0100] Furthermore, refer to Figures 9 to 12 , a plurality of guide blocks 65 protruding radially away from the tooth disk through hole 62 are provided on the outer peripheral surface of the tooth disk body 61; correspondingly, a plurality of guide grooves 53 corresponding to the guide blocks 65 respectively are opened on the inner ring surface of the ring body 51, and the guide blocks 65 can move up and down relatively in the corresponding guide grooves 53. The plurality of guide grooves 53 can limit and guide the up and down movement of the corresponding guide blocks 65 installed therein, so that the up and down movement of the lifting engagement tooth disk relative to the check disk is stable and does not generate deflection.

[0101] Further, the inner ring surface of the ring body 51 of the outer ratchet ring includes a plurality of first anti-rotation surfaces 511 connected in sequence, and the outer peripheral surface of the disk body 61 of the lifting and meshing gear disk includes a plurality of second anti-rotation surfaces 611 connected in sequence. Each of the first anti-rotation surfaces 511 and each of the second anti-rotation surfaces 611 together form an integral surface, and the integral surface is non-cylindrical, that is, the integral surface is not continuous in the first direction and the second direction. More preferably, both the first anti-rotation surface 511 and the second anti-rotation surface 611 are provided as planes and are in surface contact with each other. The number of the first anti-rotation surfaces 511 is equal to the number of the second anti-rotation surfaces 611 and they are in contact and cooperate in pairs to prevent the relative rotation of the outer ratchet ring 5 and the lifting and meshing gear disk; alternatively, the plurality of first anti-rotation surfaces 511 can be the same or different, and the plurality of second anti-rotation surfaces 611 can be the same or different, as long as the corresponding first anti-rotation surface and the second anti-rotation surface are in shape cooperation, and the anti-rotation surfaces as a whole can prevent the relative rotation of the ratchet ring and the lifting and meshing gear disk in the circumferential direction. Even more preferably, a guide block 65 is arranged on each of the plurality of second anti-rotation surfaces 611 with equal adjacent radial angles. In this way, through the contact and cooperation between the first anti-rotation surface 511 and the second anti-rotation surface 611, the lifting and meshing gear disk can only move up and down relative to the ratchet ring and cannot rotate relatively, so that the main rotating disk can realize the engagement and separation of the meshing teeth 64 and the driven teeth 22 by driving the lifting of the lifting and meshing gear disk, and further achieve the purpose of operably connecting and separating the main rotating disk and the rotating wheel. On the other hand, if the guide block 65 and the guide groove 53 are closely matched in the circumferential direction, it can also play a role in promoting the circumferential linkage of the lifting and meshing gear disk and the ratchet ring.

[0102] Further, in this embodiment, the number of both the first anti-rotation surfaces 511 and the second anti-rotation surfaces 611 is set to 9, and the number of both the guide blocks 65 and the guide grooves 53 is set to 3. Therefore, not only are the first anti-rotation surfaces 511 evenly distributed relative to the inner ring surface of the ring body 51 and the second anti-rotation surfaces 611 evenly distributed relative to the outer peripheral surface of the disk body 61, but also the guide blocks 65 and the guide grooves 53 are evenly distributed relative to the entire first anti-rotation surfaces 511 and the entire second anti-rotation surfaces 611 respectively. So, the ratchet ring 5 and the lifting and meshing gear disk are in contact and cooperation and receive a plurality of uniform anti-rotation forces, and the anti-rotation effect is good. And each guide block 65 can ensure the stable movement of the lifting and meshing gear disk in the lifting direction under the limiting action of the corresponding guide groove 53.

[0103] Please refer to Figure 4 、 Figure 9 and Figure 10, preferably, an arc-shaped groove 55 corresponding to each driving block 13 is formed between each pawl arm 541 and the outer ring surface. The driving block 13 includes a driving plate 131 and a slider 132 provided at the end of the driving plate 131. The driving plate 131 is inserted into the corresponding arc-shaped groove 55. One end of the ring body 51 facing the partition plate 412 is provided with a plurality of ring grooves 512 that are radially concave with respect to the outer ring surface. The driving plate 131 can slide in the corresponding arc-shaped groove 55 and perform a circumferential movement at a certain angle, and the slider 132 can move along the ring groove 512. The ring grooves 512, the pawl arms 541, and the arc-shaped grooves 55 correspond one by one. In this embodiment, the pawls 54, the arc-shaped grooves 55, and the ring grooves 512 are preferably provided in three. Therefore, each driving plate 131 and the slider 132 are both guided and limited by the corresponding arc-shaped groove 55 and the ring groove 512, so that the rotation of the main rotating disk relative to the outer pawl ring 5 is stable and accurate, and further, it can reliably realize that the main rotating disk drives the lifting engagement gear disk to lift and connect or separate from the rotating wheel 2.

[0104] , further referring to Figure 4 、 Figure 9 and Figure 10 , the driving block 13 further includes a notch 133 provided at the end of the driving plate 131. In this embodiment, the notch 133 is located at the middle position of the slider 132. The ring body 51 is respectively provided with a first stop surface 513 and a second stop surface 514 at both ends of the ring groove 512, and a limit protrusion 515 is provided at a position close to the second stop surface 514 in the ring groove 512. When the main rotating disk is driven so that the slider 132 is adjacent to the second stop surface 514 and the notch 133 moves to be engaged with the limit protrusion 515, the lifting engagement gear disk and the rotating wheel 2 are connected in a manner that the engagement teeth 64 are engaged with the driven teeth 22, as shown in Figures 22 - 24 ; when the main rotating disk is driven so that the notch 133 is separated from the limit protrusion 515 and the notch 133 is adjacent to the first stop surface 513, the lifting engagement gear disk and the rotating wheel 2 are separated in a manner that the engagement teeth 64 are disengaged from the driven teeth 22. In this embodiment, each notch 133 can limit the rotation of the driving plate 131, prevent the accidental rotation of the driving plate 131, and further ensure the reliable maintenance of the rising height of the lifting rod 31.

[0105] The following combines Figures 15 to 24 and according to the above description of the height adjustment device embodiment, makes a more detailed description of the rising and falling working modes of the lifting member. As described above, the central angle corresponding to each arc-shaped groove 55 determines the rotation angle of each driving plate 131 therein, and further determines the rotatable angle of the main rotating disk relative to the outer pawl ring. Assume that the initial state of the height adjustment device 10 is that the lifting engagement gear disk is separated from the rotating wheel 2 and the lifting rod 31 is at the initial low position where it has not risen (such as Figures 15 - 16 、 Figures 19 - 21As shown in the figure, when it is necessary to raise the lifting rod 31, that is, when the height adjustment device is in the raising mode, the main rotating disk is rotated by the above rotation angle in the first direction (clockwise direction). For example, Figure 19 is rotated from the position of Figure 22 to the position shown in the figure. At this time, the lifting engagement gear disk descends under the drive of the rotating column 14 so that the engagement teeth 64 of the lifting engagement gear disk mesh with the driven teeth 22 of the rotating wheel 2, as shown in Figure 23 the figure; at this time, the slider 132 is adjacent to the second stop surface 514 and the notch 133 is engaged with the limit protrusion 515, as shown in Figure 22 the figure; further, continue to rotate the main rotating disk in the first direction (clockwise direction), and each driving block 13 abuts against the second stop surface 514 of the corresponding annular groove 512 and transmits the rotational force, so that the main rotating disk drives the anti-reverse disk to rotate synchronously, and then drives the lifting engagement gear disk to rotate while driving the rotating wheel 2 to rotate synchronously. The rotating wheel 2 rotating in the first direction drives the lifting rod 31 to rise. When the lifting rod 31 rises to the desired height or the maximum height (such as Figure 17 , 18 shown in the figure), stop driving the main rotating disk. At this time, the pawl tooth 542 engaged with the ratchet tooth 4131 is blocked by the anti-reverse action of the ratchet tooth 4131 to prevent the lifting engagement gear disk from rotating in the second direction (counterclockwise direction). Therefore, even if pressure is applied to the lifting member 31, the lifting member 31 cannot descend, and the rising height of the lifting rod 31 is thus maintained. When it is necessary to lower the raised lifting rod 31, that is, when the height adjustment device is in the lowering mode, first rotate the main rotating disk in the second direction (counterclockwise direction) and make it rotate the above rotation angle relative to the outer pawl ring (that is, from Figure 22 the position shown in the figure is rotated to Figure 19At the position shown, the lifting and engaging gear disk rises under the drive of the rotating column 14 so that the engaging teeth 64 of the lifting and engaging gear disk are separated from the driven teeth 22 of the rotating wheel 2, and each driving block 13 abuts against the first stop surface 513 of the corresponding annular groove 512. At this time, under the anti-reverse effect formed by the engagement of the pawl teeth 542 and the ratchet teeth 4131, even if the main rotating disk is continuously driven in the second direction, the main rotating disk cannot further rotate in the second direction (counterclockwise direction). That is to say, at this time, the anti-reverse function of the anti-reverse assembly on the pawl ring, the main rotating disk and the lifting and engaging gear disk still exists. However, since the engaging teeth 64 of the lifting and engaging gear disk are separated from the driven teeth 22 of the rotating wheel 2, the anti-reverse function of the anti-reverse assembly on the rotating wheel 2 has been released. At this time, if pressure is applied to the lifting disk 32, the lifting rod 31 will drive the rotating wheel 2 to rotate in the second direction (counterclockwise direction) while descending. When the lifting rod 31 returns or returns to the initial low position, the lifting rod 31 stops descending and waits for the next ascent, and so on. By applying pressure to the lifting disk 32, the lifting rod can be continuously lowered until it returns to the initial low position. At this time, if it is necessary to maintain the lowered height of the lifting rod, the main rotating disk can be rotated in the first direction according to the foregoing method so that the main driving member 1 is connected to the driven member 2. Then, the driven member 2 is locked again by the anti-reverse assembly, so that it cannot rotate in the second direction, thereby maintaining the lowered height of the lifting rod. Therefore, the height adjustment device provided by the present utility model can achieve height retention in both the elevation mode and the descent mode. However, since the drive of the main rotating disk can be more precisely controlled, a better height fine-tuning effect can be achieved.

[0106] Please refer to Figure 4 、 Figure 8 , specifically, a plurality of buckling positions 16 are provided on the inner circumferential surface of the annular disk portion 12 of the main rotating disk, and a circle of buckling protrusions 414 are provided on the circumferential shell 411 of the sleeve. The buckling positions 16 are buckled with the buckling protrusions 414. Thus, the main rotating disk can rotate relative to the circumferential shell 411 in the circumferential direction along the first direction and the second direction, and the main rotating disk cannot be axially separated upward relative to the circumferential shell 411. Refer to Figure 2 、 Figure 8 and Figure 13, on the outer peripheral wall of one end of the cylindrical peripheral shell 411 away from the inner ratchet 413, there is a buckle 415 and a clamping block 416. The chassis 42 includes a bottom shell 421 and a peripheral shell 422 vertically extending around the edge of the bottom shell 421. A clamping groove 423 passes through the inner peripheral surface of the peripheral shell 422 and penetrates the bottom shell 421; at the junction of the bottom shell 421 and the peripheral shell 422, there is a clamping hole 424, the clamping hole 424 penetrates the bottom shell 421 and is concave in the peripheral shell 422. The buckle 415 is in clamping fit with the clamping groove 423, and the clamping block 416 is in clamping fit with the clamping hole 424. Further preferably, the buckle 415 and the clamping block 416 are oppositely arranged in the radial direction of the cylindrical peripheral shell 411, and the clamping groove 423 and the clamping hole 424 are oppositely arranged in the radial direction of the peripheral shell 422. Therefore, the sleeve 41 is reliably fixedly connected to the chassis 42, making the structure stable and providing a rotating space for the rotating wheel 2.

[0107] Please refer to Figure 5 , Figure 6 and Figure 8 , preferably, the hub 21 is located between the partition 412 and the chassis 42. On the bottom surface of the hub 21 facing the chassis 42, there are multiple support protrusions 26. By setting the support protrusions 26, the friction between the bottom surface of the hub 21 and the chassis 42 can be reduced. Furthermore, the rotational wear of the hub 21 is small, and the rotational driving force required is relatively reduced. In this embodiment, flanges 25 are provided at the upper and lower ends of the hub 21. However, the setting of the flanges 25 is not necessary. Other preferably, the hub 21 is set in the shape of a rotating body, which is beneficial to the stable rotation of the hub 21 in the inner cavity of the sleeve 41.

[0108] Please refer to Figure 7 and Figure 14 , specifically, the lifting member 3 further includes a lifting disk 32 fixedly connected to the rod end of the lifting rod 31. In this embodiment, on one side of the lifting disk 32 facing the lifting rod 31, there is an insertion post 321, which can be inserted and matched with the anti-rotation hole 312; in this embodiment, the insertion post 321 is configured in the shape of a four-straight-sided column, and after being matched with the four-straight-sided column hole-shaped anti-rotation hole 312, an unrotatable connection relationship is formed between the lifting member 3 and the lifting disk 32. Refer to Figure 3 , Figure 4 and Figure 7 , Figure 18 , the rotating column 14 is provided with a column through hole 141, and the column through hole 141 is communicated with the disk through hole 111 provided on the disk portion 11. The lifting rod 31 passes through the threaded through hole 23, the inner cavity of the sleeve 4121, the ring hole 52, the column through hole 141 and the disk through hole 111. The lifting disk 32 moves relatively above the outside of the disk portion 11. By setting the lifting disk 32, the disk bottom 322 can provide a larger force-bearing surface, facilitating the application of pressure from the outside to the lifting rod 31.

The main driving member 1 partially protrudes from the side wall of the sole 40, and the size of the main driving member 1 can be set according to actual needs. For example, when the height adjustment device 10 is applied to the footwear article 100, the size of the main driving member 1 needs to be set larger to provide a larger torque for the user to rotate the main driving member 1. The lifting member 3 is located under the insole 30 for adjusting the height of the insole 30. As Figure 28 , 29 shown, the height adjustment device 10 is partially disposed in the sole 40. Preferably, the sole 40 is provided with a groove for accommodating the height adjustment device 10.

This solution is mainly applicable to functional shoes and health shoes and is very friendly to people with flat feet. In other preferred embodiments of the present utility model, a height adjustment device 10 can also be respectively disposed at the arch position and the heel position of the insole, as Figure 30 shown. In this way, one of the height adjustment devices can be adjusted separately according to needs, or two height adjustment devices can be adjusted simultaneously. In addition, the two adjustment devices are coordinated, so that the height adjustment of the insole is continuous, increasing the height adjustment range and comfort, and can realize the free switching between comfortable sports shoes and high heels, wedge shoes, etc.

[0112] Therefore, the present utility model can adjust the local height of the insole at any time according to the user's usage requirements at different times and in different situations, realizing the function of one shoe for multiple uses. Of course, the number and the setting position of the height adjustment device 10 can both be set according to the usage requirements of the footwear article. The present utility model does not limit its setting position and number.
