Description

TECHNICAL FIELD

[0001] This utility model relates to the technical field of lacing buckles, specifically to a pressing and rotating lacing buckle.BACKGROUND

[0002] Lacing buckles are mainly used in shoes, clothing, backpacks, and rehabilitation products to tighten or loosen laces. Lacing buckles are widely used, and products with such lacing buckles provide users with conveniences. However, existing manual tensioning buttons still have some problems in use.

[0003] For example, the Chinese invention application with publication No. CN108791997A provides a lacing device, including a rotor and a stator. The stator includes a sleeve, and the rotor includes an upper cover and a winding groove arranged sequentially from top to bottom. The sleeve is provided with a pawl, and the upper cover is correspondingly provided with teeth. Both the rotor and the stator are provided with a gear structure, through which the pawl and teeth are engaged or disengaged. With the gear structure, when the upper cover is pressed, the upper cover coordinate with the winding groove, and the teeth of the upper cover engage with the pawl of the sleeve, at which point the lace-tying system is in the first gear. When the rotor is rotated forward, the lace will wind onto the winding groove in the tightening direction. In this gear, the rotor cannot reverse, thus achieving the function of tightening the lace. When the upper cover is pulled up, the pawl disengages from the teeth, the rotor is no longer subject to unidirectional constraint, and the upper cover disengages from the winding groove. At this time, both the upper cover and the winding groove can rotate freely in both directions, thus achieving automatic loosening of the laces. For example, CN218635442U provides a lacing buckle. To loosen the shoelaces, the cover is first pulled upwards, then rotated, allowing the shoelaces to loosen. When the cover is pressed down, the ratchet engages with the one-way teeth. As the user rotates the cover, the cover can only rotate in one direction, allowing the shoelaces to wind around the reel surface, thereby tightening the shoelace.

[0004] The aforementioned lacing buckles typically use radially actuated covers to switch between loosening and retracting the laces. This means that both loosening and retracting require manual operation by the user bending over. Furthermore, due to the use of a clutch structure, the structure is usually quite complex, and repeated pulling can easily cause damage.SUMMARY

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.Embodiment 1

[0022] As shown in FIGS. 1-5, which provide a pressing and rotating lacing buckle, including a fastening seat 10 disposed on a shoe upper, tongue, heel, clothing, hat, or bag. A take-up seat 20 is disposed on the fastening seat 10, and a take-up wheel 30 is disposed within a take-up cavity 21 in the take-up seat 20. A reset spring 40, a transmission wheel 50, and a cap 60 are sequentially disposed on the take-up wheel 30. The cap 60 drives the take-up wheel 30 to rotate within the take-up seat 20 via the transmission wheel 50. A button 70 is disposed on the cap 60. When the button 70 is pressed, it acts on the transmission wheel 50 and compresses the reset spring 40, thereby separating and resetting the force-transmission connection between the cap 60 and the take-up wheel 30.

[0023] As shown in FIGS. 3-5, a one-way brake 80 is disposed between the cap 60 and the take-up seat 20. The one-way brake 80 causes the cap 60 to drive the take-up wheel 30 to rotate unidirectionally along the take-up direction and lock against reverse rotation.

[0024] As shown in FIGS. 4 and 5, the fastening seat 10 includes a connecting piece 11, and a mounting groove 12 is provided on the upper surface of the connecting piece 11. The take-up seat 20 is disposed in the mounting groove 12, and a winding space for laces is formed between the mounting groove 12 and the winding cavity 21. Specifically, the bottom of the take-up seat 20 cooperates with the slot holes 16 and positioning holes 17 in the mounting groove 12 by several snap fasteners 25 and several positioning guide posts 26.

[0025] Optionally, the connecting piece 11 can be installed on the shoe upper, shoe tongue, shoe heel, clothing, hat, or bag through the fixing holes 18 at the edge position, or the connecting piece 11 can be fixed by means of adhesive bonding or other methods.

[0026] As shown in FIGS. 3-5, a central post 13 is provided in the middle of the mounting groove 12. The central post 13 passes through the winding center hole 33 of the take-up wheel 30 and the transmission center hole 51 of the transmission wheel 50 in sequence, and its upper end corresponds to the mating center hole 71 of the button 70. The reset spring 40 is sleeved on the central post 13 between the take-up wheel 30 and the transmission wheel 50.

[0027] Specifically, the take-up wheel 30 is arranged in the take-up cavity 21 due to a rotating ring portion 31. A winding post 32 is provided at the lower part of the rotating ring portion 31. The winding post 32 is rotatably sleeved on the central post 13 through the winding center hole 33. The rotating ring portion 31 cooperates with the take-up rotation limit block 22 in the take-up cavity 21 to form a lace take-up space between the mounting groove 12, the rotating ring portion 31, and the winding post 32. Compared to existing take-up wheels that have an I-shaped structure as the compartment for laces, this design uses the mounting groove, the rotating ring portion of the take-up wheel, and a winding post to form the lace compartment. This allows for a smaller thickness of the pressing and rotating lacing buckle, resulting in a thinner design.

[0028] Specifically, the take-up cavity 21 has a first hole 23 and a second hole 24 on the radial side of the take-up seat 20. Corresponding to the first hole 23 and the second 24, a first groove 14 and a second groove 15 are provided on the fastening seat 10. Meanwhile, the winding post 32 is provided with a first receiving hole 34 and a second receiving hole 35 surrounding the winding center hole 33. The first receiving hole 34 and the second receiving hole 35 correspond to the first hole 23 and the second hole 24.

[0029] Optionally, the first hole 23 and the second hole 24 correspond to the entrances of the first receiving hole 34 and the second receiving hole 35, and the take-up seat 20 is provided with outlet holes 27 corresponding to the outlets of the first hole 23 and the second hole 24.

[0030] As shown in FIGS. 4 and 5, the one-way brake 80 includes a plurality of pawl arms 81. Each pawl arm 81 is provided with a pawl portion 82 at one end and a brake connection seat 83 at the other end. The brake connection seats 83 are sequentially mounted in the brake connection holes 28 on the upper edge of the take-up seat 20. The pawl arms 81 are distributed along the take-up direction and cooperate with the one-way ratchet portions 65 on the inner wall of the cap 60. Based on the above structure, stable nesting assembly is achieved during use, forming a limiting engagement to prevent rotation and facilitate the winding of the laces.

[0031] As shown in FIGS. 3-5, the transmission wheel 50 is sleeved on the central post 13 through the transmission center hole 51. The upper part of the transmission wheel 50 is provided with a first driving tooth portion 53, and a second driving tooth portion 62 corresponding to the first driving tooth portion 53 is provided around the pressing hole 61 on the cap 60. The reset spring 40 causes the first driving tooth portion 53 and the second driving tooth portion 62 to engage tightly. As shown in FIGS. 3-5, the lower part of the transmission wheel 50 is provided with a second transmission tooth portion 52a, and a corresponding first transmission tooth portion 36a is provided on the upper part of the winding wheel 30. Based on the above structure, it is easy to use for elastic lifting, and the engagement structure allows a linkage rotation.

[0032] Specifically, a plurality of pressing limiting grooves 63 are evenly provided on the side wall of the pressing hole 61, and limiting blocks 72 corresponding to the pressing limiting grooves 63 are provided on the outer peripheral wall of the button 70. The button 70 is secured within the pressing hole 61 by the limiting blocks 72, preventing it from falling off. Optionally, a pressing guide slot 64 is also provided on the side wall of the pressing hole 61, and a guide block 73 corresponding to the pressing guide slot 64 is provided on the outer peripheral wall of the button 70.

[0033] Specifically, the one-way ratchet portion 65 is arranged around the second driving tooth portion 62, and a cap retaining ring 66 is provided at the lower end of the cap 60, which corresponds to the retaining ring mating portion 210 on the outer peripheral wall of the take-up seat 20. In the pressing and rotating lacing buckle of this embodiment, the reset spring, the transmission wheel, the cap, and the button form a structure similar to a push-to-turn ballpoint pen. The button actuates the transmission wheel, converting linear motion into rotation, thereby changing the engagement state between the cap and the transmission wheel. This causes the first and second transmission teeth between the transmission wheel and the take-up wheel to engage and disengage, allowing the take-up locking state of the lacing buckle to be switched simply by pressing the button. The specific operation of the reset spring, transmission wheel, cap, and button is described in Embodiment 2.Embodiment 2

[0034] As shown in FIGS. 6-10, the pressing and rotating lacing buckle in Embodiment 2 differs from Embodiment 1 in that the cap 60 has a different shape, eliminating the threaded structure of Embodiment 1 and employing a polyhedron structure to achieve anti-slip functionality.

[0035] Additionally, as shown in FIGS. 9 and 10, the one-way brake 80 also includes a brake connection ring 84. Each brake connection seat 83 is fixed to the brake connection ring 84, and the brake connection ring 84 cooperates with the brake receiving platform 29 within the take-up seat 20. The integrated design of the one-way brake 80 is more conducive to production and assembly.

[0036] Secondly, in Embodiment 2, it eliminates the guide block of the button and the corresponding pressing guide slot on the cap 60. The limiting blocks 72 are located at the bottom of the button 70 and protrudes therefrom, which makes it fit better with the pressing limiting grooves 63 of the cap 60. This eliminates the need for a pressing guide slot on the button, allows the limiting blocks to be hidden, and makes the button thinner, resulting in a lower limiting position and a thinner overall design.

[0037] As shown in FIGS. 9-11, the first driving tooth portion 53 includes a horizontal clutch tooth surface 53a inclined around the central post 13, and a limiting clutch tooth root 53b at the lower part of the horizontal clutch tooth surface 53a. Corresponding to the horizontal clutch tooth surface 53a, a clutch tooth portion 62a that matches with the horizontal clutch tooth surface 53a is provided in the second driving tooth portion 62. A plurality of pressing limiting grooves 63 are evenly provided on the sidewall of the pressing hole 61. The limiting clutch tooth root 53b and the pressing limiting grooves 63 are evenly engaged radially around the central post 13. An inclined transition surface 62b is provided between the clutch tooth portion 62a and the pressing limit groove 63. A sawtooth portion 74 corresponding to the horizontal clutch tooth surface 53a is provided at the lower end of the button 70. The top of the sawtooth portion 74 acts on the surface of the horizontal clutch tooth surface 53a, causing the transmission wheel 50 to rotate around the central post 13 with the teeth of the sawtooth portion 74. The transmission wheel 50 switches between the engagement state of the clutch tooth portion 62a with the horizontal clutch tooth surface 53a and the engagement state of the limiting clutch tooth root 53b with the pressing limiting grooves 63.

[0038] As shown in FIGS. 12 and 15, the pressing and rotating lacing buckle is in its initial state, where the reset spring 40 is in the extended state. The reset spring 40 presses the transmission wheel 50, and the first driving tooth portion 53 on the transmission wheel 50 engages with the second driving tooth portion 62 on the cap 60. Specifically, the horizontal clutch tooth surface 53a engages with the clutch tooth portion 62a, and the second transmission tooth portion 52a on the lower side of the transmission wheel 50 engages with the first transmission tooth portion 36a on the take-up wheel 30. At this time, the cap 60 is rotated along the ratchet-defined direction, and the transmission wheel 50 rotates the take-up wheel 30 in the take-up seat 20. The laces are wound from the first hole 23 and the second hole 24 of the take-up seat 20 into the winding post 32 of the take-up wheel 30 and received, effectively tightening the gloves, shoes, etc. used.

[0039] As shown in FIGS. 13 and 16, after the button 70 is pressed for the first time, the button 70 moves axially downward along the central post 13 within the pressing hole 61 under the restriction of the pressing limiting grooves 63 of the cap 60 by the limiting blocks 72. This acts on the transmission wheel 50 and compresses the reset spring 40. The sawtooth portion 74 at the lower end of the button 70 acts on the surface of the horizontal clutch tooth surface 53a of the first driving tooth portion 53, causing the transmission wheel 50 to move axially downward while rotating around the central post 13 with the teeth of the sawtooth portion 74, until the first transmission tooth portion 36a and the second transmission tooth portion 52a reach the engagement limit.

[0040] As shown in FIGS. 14 and 17, after the button 70 is released, the reset spring 40 pushes the transmission wheel 50 to move axially upward for return. Since the transmission wheel 50 rotated when the button 70 was pressed for the first time, the first driving tooth portion 53 on the returned transmission wheel 50 no longer engages with the second driving tooth portion 62 on the cap 60. Specifically, the horizontal clutch tooth surface 53a interacts with the inclined transition surface 62b. Under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide upward along the inclined transition surface 62b.

[0041] As shown in FIGS. 15 and 18, under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide upward along the inclined transition surface 62b, causing the transmission wheel 50 to rotate upward. This causes the limiting clutch tooth root 53b of the first driving tooth portion 53 to enter the pressing limiting grooves 63, so that the limiting clutch tooth root 53b and the limiting blocks 72 of the button 70 are both in the pressing limiting grooves 63. At this time, the transmission wheel 50 is pressed by the reset spring 40 at the highest point of the central post 13, causing the first transmission tooth portion 36a and the second transmission tooth portion 52a to separate from each other. This allows the take-up wheel 30 to disengage from the locking limit, enabling the unfolding and use of gloves, shoes, etc. It also frees the user's hands during use. For example, when applied to shoes, if the user wants to take off their shoes, they only need to press the button of the lacing buckle on the right shoe with their left foot to take off their right shoe, effectively freeing their hands and eliminating the need to bend over. This also solves the contradiction between the pull-out force and the product firmness in the current industry and improves the stability of use.

[0042] As shown in FIGS. 16 and 19, when button 70 is pressed again, as the transmission wheel 50 moves axially downward, the limiting clutch tooth root 53b of the first driving tooth portion 53 leaves the pressing limiting grooves 63. The top of the sawtooth portion 74 acts again on the surface of the horizontal clutch tooth surface 53a of the first driving tooth portion 53, causing the transmission wheel 50 to move axially downward while rotating around the central post 13 with the teeth of the sawtooth portion 74, until the first transmission tooth portion 36a and the second transmission tooth portion 52a reach the engagement limit again. After releasing the button 70, the reset spring 40 pushes the transmission wheel 50 upward to return. Since the transmission wheel 50 rotates when the button 70 is pressed for the second time, the limiting clutch tooth root 53b of the first driving tooth portion 53 on the returned transmission wheel 50 is no longer in the corresponding pressing limiting groove 63. Specifically, the horizontal clutch tooth surface 53a interacts with the clutch tooth portion 62a. Under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide upward along the clutch tooth portion 62a until they engage with each other. At this time, the pressing and rotating lacing buckle is in the initial state again.Embodiment 3

[0043] As shown in FIGS. 20-25, compared with Embodiments 1 and 2, the lower part of the transmission wheel 50 of the pressing and rotating lacing buckle in Embodiment 3 is provided with several transmission pin holes 52b, and several transmission pins 36b are provided on the upper part of the take-up wheel 30. The transmission pin holes 52b and the transmission pins 36b are used for force-transmission connections.

[0044] As shown in FIGS. 23-25, the first driving tooth portion 53 is implemented as axially oriented triangular teeth 53c distributed radially, and the second driving tooth portion 62 is implemented as radially oriented triangular gears 62c distributed axially. The axially oriented triangular teeth 53c are pressed into the radially oriented triangular gears 62c by the reset spring 40. The axially oriented triangular teeth 53c and the radially oriented triangular gears 62c are switched between disengagement and reset by the transmission wheel 50 acting on the button 70. Optionally, the upper end of the axially oriented triangular teeth 53c is provided with first axial guide bevel teeth 53d, and the lower part of the radially oriented triangular gear portion 62c is provided with second axial guide bevel teeth 62d. The first axial guide bevel teeth 53d and the second axial guide bevel teeth 62d are axially guided by the reset spring 40 so that the axially oriented triangular teeth 53c and the radially oriented triangular gears 62c engage together. Under the action of the reset spring 40, the first axial guide bevel teeth 53d and the second axial guide bevel teeth 62d can achieve quick engagement of the axially oriented triangular teeth 53c and the radially oriented triangular gears 62c.

[0045] In use, the pressing and rotating lacing buckle is in its initial state, with the reset spring extended. The reset spring presses against the transmission wheel, and the transmission pin holes at the lower part of the transmission wheel engage with the transmission pins on the upper part of the take-up wheel. The first driving tooth portion and the second driving tooth portion engages with each other. Specifically, the axially oriented triangular teeth are pressed against the radially oriented triangular gears by the reset spring. At this time, rotating the cap along the ratchet-defined direction causes the take-up wheel to rotate within the take-up seat, winding the laces from the first and second holes of the take-up seat into the winding post of the take-up wheel to receive them, effectively tightening gloves, shoes, etc.

[0046] Subsequently, after pressing the button, the button moves downward axially along the central post within the pressing hole under the restriction of the pressing limiting grooves of the cap by the limiting blocks. This acts on the transmission wheel and compresses the reset spring, causing the first and second drive tooth portions to disengage from each other. This allows the take-up wheel to disengage from the locking limit, enabling the unfolding of gloves, shoes, etc., and freeing the user's hands during use. For example, when using it on shoes, if the user wants to take off their shoes, they only need to press the button of the lacing buckle on the right shoe with their left foot to remove their right shoe, effectively freeing their hands and eliminating the need to bend over. After releasing the button, the reset spring pushes the transmission wheel to move upward axially to return. The axially oriented triangular teeth engage with the radially oriented triangular gears through the reset spring, and thus the pressing and rotating lacing buckle returns to its initial state.

[0047] The pressing and rotating lacing buckle provided in the embodiments of the utility model is provided with a reset spring, a transmission wheel, a cap, and a button. The cap drives the take-up wheel to rotate within the take-up seat via the transmission wheel. When the button is pressed, it acts on the transmission wheel and compresses the reset spring, separating and resetting the transmission connection between the cap and the take-up wheel. This allows for switching or releasing the winding lock state of the lacing buckle simply by pressing the button, even with the feet or other ground objects, freeing up the hands and eliminating the need for bending over, thus improving the user experience.

[0048] Furthermore, the use of a one-way brake with an elastic structure ensures that the cap rotates unidirectionally under a certain force, preventing free rotation. The ratchet engagement, tooth engagement, and pin engagement results in a simple structure and a stable locking state.

[0049] Content not described in detail in this specification is related art known to those skilled in the art.

[0050] Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility model, the scope of which is defined by the appended claims and their equivalents.

TECHNICAL FIELD

[0001] This utility model relates to the technical field of lacing buckles, specifically to a pressing and rotating lacing buckle.BACKGROUND

[0002] Lacing buckles are mainly used in shoes, clothing, backpacks, and rehabilitation products to tighten or loosen laces. Lacing buckles are widely used, and products with such lacing buckles provide users with conveniences. However, existing manual tensioning buttons still have some problems in use.

[0003] For example, the Chinese invention application with publication No. CN108791997A provides a lacing device, including a rotor and a stator. The stator includes a sleeve, and the rotor includes an upper cover and a winding groove arranged sequentially from top to bottom. The sleeve is provided with a pawl, and the upper cover is correspondingly provided with teeth. Both the rotor and the stator are provided with a gear structure, through which the pawl and teeth are engaged or disengaged. With the gear structure, when the upper cover is pressed, the upper cover coordinate with the winding groove, and the teeth of the upper cover engage with the pawl of the sleeve, at which point the lace-tying system is in the first gear. When the rotor is rotated forward, the lace will wind onto the winding groove in the tightening direction. In this gear, the rotor cannot reverse, thus achieving the function of tightening the lace. When the upper cover is pulled up, the pawl disengages from the teeth, the rotor is no longer subject to unidirectional constraint, and the upper cover disengages from the winding groove. At this time, both the upper cover and the winding groove can rotate freely in both directions, thus achieving automatic loosening of the laces. For example, CN218635442U provides a lacing buckle. To loosen the shoelaces, the cover is first pulled upwards, then rotated, allowing the shoelaces to loosen. When the cover is pressed down, the ratchet engages with the one-way teeth. As the user rotates the cover, the cover can only rotate in one direction, allowing the shoelaces to wind around the reel surface, thereby tightening the shoelace.

[0004] The aforementioned lacing buckles typically use radially actuated covers to switch between loosening and retracting the laces. This means that both loosening and retracting require manual operation by the user bending over. Furthermore, due to the use of a clutch structure, the structure is usually quite complex, and repeated pulling can easily cause damage.SUMMARY

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.Embodiment 1

[0022] As shown in FIGS. 1-5, which provide a pressing and rotating lacing buckle, including a fastening seat 10 disposed on a shoe upper, tongue, heel, clothing, hat, or bag. A take-up seat 20 is disposed on the fastening seat 10, and a take-up wheel 30 is disposed within a take-up cavity 21 in the take-up seat 20. A reset spring 40, a transmission wheel 50, and a cap 60 are sequentially disposed on the take-up wheel 30. The cap 60 drives the take-up wheel 30 to rotate within the take-up seat 20 via the transmission wheel 50. A button 70 is disposed on the cap 60. When the button 70 is pressed, it acts on the transmission wheel 50 and compresses the reset spring 40, thereby separating and resetting the force-transmission connection between the cap 60 and the take-up wheel 30.

[0023] As shown in FIGS. 3-5, a one-way brake 80 is disposed between the cap 60 and the take-up seat 20. The one-way brake 80 causes the cap 60 to drive the take-up wheel 30 to rotate unidirectionally along the take-up direction and lock against reverse rotation.

[0024] As shown in FIGS. 4 and 5, the fastening seat 10 includes a connecting piece 11, and a mounting groove 12 is provided on the upper surface of the connecting piece 11. The take-up seat 20 is disposed in the mounting groove 12, and a winding space for laces is formed between the mounting groove 12 and the winding cavity 21. Specifically, the bottom of the take-up seat 20 cooperates with the slot holes 16 and positioning holes 17 in the mounting groove 12 by several snap fasteners 25 and several positioning guide posts 26.

[0025] Optionally, the connecting piece 11 can be installed on the shoe upper, shoe tongue, shoe heel, clothing, hat, or bag through the fixing holes 18 at the edge position, or the connecting piece 11 can be fixed by means of adhesive bonding or other methods.

[0026] As shown in FIGS. 3-5, a central post 13 is provided in the middle of the mounting groove 12. The central post 13 passes through the winding center hole 33 of the take-up wheel 30 and the transmission center hole 51 of the transmission wheel 50 in sequence, and its upper end corresponds to the mating center hole 71 of the button 70. The reset spring 40 is sleeved on the central post 13 between the take-up wheel 30 and the transmission wheel 50.

[0027] Specifically, the take-up wheel 30 is arranged in the take-up cavity 21 due to a rotating ring portion 31. A winding post 32 is provided at the lower part of the rotating ring portion 31. The winding post 32 is rotatably sleeved on the central post 13 through the winding center hole 33. The rotating ring portion 31 cooperates with the take-up rotation limit block 22 in the take-up cavity 21 to form a lace take-up space between the mounting groove 12, the rotating ring portion 31, and the winding post 32. Compared to existing take-up wheels that have an I-shaped structure as the compartment for laces, this design uses the mounting groove, the rotating ring portion of the take-up wheel, and a winding post to form the lace compartment. This allows for a smaller thickness of the pressing and rotating lacing buckle, resulting in a thinner design.

[0028] Specifically, the take-up cavity 21 has a first hole 23 and a second hole 24 on the radial side of the take-up seat 20. Corresponding to the first hole 23 and the second 24, a first groove 14 and a second groove 15 are provided on the fastening seat 10. Meanwhile, the winding post 32 is provided with a first receiving hole 34 and a second receiving hole 35 surrounding the winding center hole 33. The first receiving hole 34 and the second receiving hole 35 correspond to the first hole 23 and the second hole 24.

[0029] Optionally, the first hole 23 and the second hole 24 correspond to the entrances of the first receiving hole 34 and the second receiving hole 35, and the take-up seat 20 is provided with outlet holes 27 corresponding to the outlets of the first hole 23 and the second hole 24.

[0030] As shown in FIGS. 4 and 5, the one-way brake 80 includes a plurality of pawl arms 81. Each pawl arm 81 is provided with a pawl portion 82 at one end and a brake connection seat 83 at the other end. The brake connection seats 83 are sequentially mounted in the brake connection holes 28 on the upper edge of the take-up seat 20. The pawl arms 81 are distributed along the take-up direction and cooperate with the one-way ratchet portions 65 on the inner wall of the cap 60. Based on the above structure, stable nesting assembly is achieved during use, forming a limiting engagement to prevent rotation and facilitate the winding of the laces.

[0031] As shown in FIGS. 3-5, the transmission wheel 50 is sleeved on the central post 13 through the transmission center hole 51. The upper part of the transmission wheel 50 is provided with a first driving tooth portion 53, and a second driving tooth portion 62 corresponding to the first driving tooth portion 53 is provided around the pressing hole 61 on the cap 60. The reset spring 40 causes the first driving tooth portion 53 and the second driving tooth portion 62 to engage tightly. As shown in FIGS. 3-5, the lower part of the transmission wheel 50 is provided with a second transmission tooth portion 52a, and a corresponding first transmission tooth portion 36a is provided on the upper part of the winding wheel 30. Based on the above structure, it is easy to use for elastic lifting, and the engagement structure allows a linkage rotation.

[0032] Specifically, a plurality of pressing limiting grooves 63 are evenly provided on the side wall of the pressing hole 61, and limiting blocks 72 corresponding to the pressing limiting grooves 63 are provided on the outer peripheral wall of the button 70. The button 70 is secured within the pressing hole 61 by the limiting blocks 72, preventing it from falling off. Optionally, a pressing guide slot 64 is also provided on the side wall of the pressing hole 61, and a guide block 73 corresponding to the pressing guide slot 64 is provided on the outer peripheral wall of the button 70.

[0033] Specifically, the one-way ratchet portion 65 is arranged around the second driving tooth portion 62, and a cap retaining ring 66 is provided at the lower end of the cap 60, which corresponds to the retaining ring mating portion 210 on the outer peripheral wall of the take-up seat 20. In the pressing and rotating lacing buckle of this embodiment, the reset spring, the transmission wheel, the cap, and the button form a structure similar to a push-to-turn ballpoint pen. The button actuates the transmission wheel, converting linear motion into rotation, thereby changing the engagement state between the cap and the transmission wheel. This causes the first and second transmission teeth between the transmission wheel and the take-up wheel to engage and disengage, allowing the take-up locking state of the lacing buckle to be switched simply by pressing the button. The specific operation of the reset spring, transmission wheel, cap, and button is described in Embodiment 2.Embodiment 2

[0034] As shown in FIGS. 6-10, the pressing and rotating lacing buckle in Embodiment 2 differs from Embodiment 1 in that the cap 60 has a different shape, eliminating the threaded structure of Embodiment 1 and employing a polyhedron structure to achieve anti-slip functionality.

[0035] Additionally, as shown in FIGS. 9 and 10, the one-way brake 80 also includes a brake connection ring 84. Each brake connection seat 83 is fixed to the brake connection ring 84, and the brake connection ring 84 cooperates with the brake receiving platform 29 within the take-up seat 20. The integrated design of the one-way brake 80 is more conducive to production and assembly.

[0036] Secondly, in Embodiment 2, it eliminates the guide block of the button and the corresponding pressing guide slot on the cap 60. The limiting blocks 72 are located at the bottom of the button 70 and protrudes therefrom, which makes it fit better with the pressing limiting grooves 63 of the cap 60. This eliminates the need for a pressing guide slot on the button, allows the limiting blocks to be hidden, and makes the button thinner, resulting in a lower limiting position and a thinner overall design.

[0037] As shown in FIGS. 9-11, the first driving tooth portion 53 includes a horizontal clutch tooth surface 53a inclined around the central post 13, and a limiting clutch tooth root 53b at the lower part of the horizontal clutch tooth surface 53a. Corresponding to the horizontal clutch tooth surface 53a, a clutch tooth portion 62a that matches with the horizontal clutch tooth surface 53a is provided in the second driving tooth portion 62. A plurality of pressing limiting grooves 63 are evenly provided on the sidewall of the pressing hole 61. The limiting clutch tooth root 53b and the pressing limiting grooves 63 are evenly engaged radially around the central post 13. An inclined transition surface 62b is provided between the clutch tooth portion 62a and the pressing limit groove 63. A sawtooth portion 74 corresponding to the horizontal clutch tooth surface 53a is provided at the lower end of the button 70. The top of the sawtooth portion 74 acts on the surface of the horizontal clutch tooth surface 53a, causing the transmission wheel 50 to rotate around the central post 13 with the teeth of the sawtooth portion 74. The transmission wheel 50 switches between the engagement state of the clutch tooth portion 62a with the horizontal clutch tooth surface 53a and the engagement state of the limiting clutch tooth root 53b with the pressing limiting grooves 63.

[0038] As shown in FIGS. 12 and 15, the pressing and rotating lacing buckle is in its initial state, where the reset spring 40 is in the extended state. The reset spring 40 presses the transmission wheel 50, and the first driving tooth portion 53 on the transmission wheel 50 engages with the second driving tooth portion 62 on the cap 60. Specifically, the horizontal clutch tooth surface 53a engages with the clutch tooth portion 62a, and the second transmission tooth portion 52a on the lower side of the transmission wheel 50 engages with the first transmission tooth portion 36a on the take-up wheel 30. At this time, the cap 60 is rotated along the ratchet-defined direction, and the transmission wheel 50 rotates the take-up wheel 30 in the take-up seat 20. The laces are wound from the first hole 23 and the second hole 24 of the take-up seat 20 into the winding post 32 of the take-up wheel 30 and received, effectively tightening the gloves, shoes, etc. used.

[0039] As shown in FIGS. 13 and 16, after the button 70 is pressed for the first time, the button 70 moves axially downward along the central post 13 within the pressing hole 61 under the restriction of the pressing limiting grooves 63 of the cap 60 by the limiting blocks 72. This acts on the transmission wheel 50 and compresses the reset spring 40. The sawtooth portion 74 at the lower end of the button 70 acts on the surface of the horizontal clutch tooth surface 53a of the first driving tooth portion 53, causing the transmission wheel 50 to move axially downward while rotating around the central post 13 with the teeth of the sawtooth portion 74, until the first transmission tooth portion 36a and the second transmission tooth portion 52a reach the engagement limit.

[0040] As shown in FIGS. 14 and 17, after the button 70 is released, the reset spring 40 pushes the transmission wheel 50 to move axially upward for return. Since the transmission wheel 50 rotated when the button 70 was pressed for the first time, the first driving tooth portion 53 on the returned transmission wheel 50 no longer engages with the second driving tooth portion 62 on the cap 60. Specifically, the horizontal clutch tooth surface 53a interacts with the inclined transition surface 62b. Under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide upward along the inclined transition surface 62b.

[0041] As shown in FIGS. 15 and 18, under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide upward along the inclined transition surface 62b, causing the transmission wheel 50 to rotate upward. This causes the limiting clutch tooth root 53b of the first driving tooth portion 53 to enter the pressing limiting grooves 63, so that the limiting clutch tooth root 53b and the limiting blocks 72 of the button 70 are both in the pressing limiting grooves 63. At this time, the transmission wheel 50 is pressed by the reset spring 40 at the highest point of the central post 13, causing the first transmission tooth portion 36a and the second transmission tooth portion 52a to separate from each other. This allows the take-up wheel 30 to disengage from the locking limit, enabling the unfolding and use of gloves, shoes, etc. It also frees the user's hands during use. For example, when applied to shoes, if the user wants to take off their shoes, they only need to press the button of the lacing buckle on the right shoe with their left foot to take off their right shoe, effectively freeing their hands and eliminating the need to bend over. This also solves the contradiction between the pull-out force and the product firmness in the current industry and improves the stability of use.

[0042] As shown in FIGS. 16 and 19, when button 70 is pressed again, as the transmission wheel 50 moves axially downward, the limiting clutch tooth root 53b of the first driving tooth portion 53 leaves the pressing limiting grooves 63. The top of the sawtooth portion 74 acts again on the surface of the horizontal clutch tooth surface 53a of the first driving tooth portion 53, causing the transmission wheel 50 to move axially downward while rotating around the central post 13 with the teeth of the sawtooth portion 74, until the first transmission tooth portion 36a and the second transmission tooth portion 52a reach the engagement limit again. After releasing the button 70, the reset spring 40 pushes the transmission wheel 50 upward to return. Since the transmission wheel 50 rotates when the button 70 is pressed for the second time, the limiting clutch tooth root 53b of the first driving tooth portion 53 on the returned transmission wheel 50 is no longer in the corresponding pressing limiting groove 63. Specifically, the horizontal clutch tooth surface 53a interacts with the clutch tooth portion 62a. Under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide upward along the clutch tooth portion 62a until they engage with each other. At this time, the pressing and rotating lacing buckle is in the initial state again.Embodiment 3

[0043] As shown in FIGS. 20-25, compared with Embodiments 1 and 2, the lower part of the transmission wheel 50 of the pressing and rotating lacing buckle in Embodiment 3 is provided with several transmission pin holes 52b, and several transmission pins 36b are provided on the upper part of the take-up wheel 30. The transmission pin holes 52b and the transmission pins 36b are used for force-transmission connections.

[0044] As shown in FIGS. 23-25, the first driving tooth portion 53 is implemented as axially oriented triangular teeth 53c distributed radially, and the second driving tooth portion 62 is implemented as radially oriented triangular gears 62c distributed axially. The axially oriented triangular teeth 53c are pressed into the radially oriented triangular gears 62c by the reset spring 40. The axially oriented triangular teeth 53c and the radially oriented triangular gears 62c are switched between disengagement and reset by the transmission wheel 50 acting on the button 70. Optionally, the upper end of the axially oriented triangular teeth 53c is provided with first axial guide bevel teeth 53d, and the lower part of the radially oriented triangular gear portion 62c is provided with second axial guide bevel teeth 62d. The first axial guide bevel teeth 53d and the second axial guide bevel teeth 62d are axially guided by the reset spring 40 so that the axially oriented triangular teeth 53c and the radially oriented triangular gears 62c engage together. Under the action of the reset spring 40, the first axial guide bevel teeth 53d and the second axial guide bevel teeth 62d can achieve quick engagement of the axially oriented triangular teeth 53c and the radially oriented triangular gears 62c.

[0045] In use, the pressing and rotating lacing buckle is in its initial state, with the reset spring extended. The reset spring presses against the transmission wheel, and the transmission pin holes at the lower part of the transmission wheel engage with the transmission pins on the upper part of the take-up wheel. The first driving tooth portion and the second driving tooth portion engages with each other. Specifically, the axially oriented triangular teeth are pressed against the radially oriented triangular gears by the reset spring. At this time, rotating the cap along the ratchet-defined direction causes the take-up wheel to rotate within the take-up seat, winding the laces from the first and second holes of the take-up seat into the winding post of the take-up wheel to receive them, effectively tightening gloves, shoes, etc.

[0046] Subsequently, after pressing the button, the button moves downward axially along the central post within the pressing hole under the restriction of the pressing limiting grooves of the cap by the limiting blocks. This acts on the transmission wheel and compresses the reset spring, causing the first and second drive tooth portions to disengage from each other. This allows the take-up wheel to disengage from the locking limit, enabling the unfolding of gloves, shoes, etc., and freeing the user's hands during use. For example, when using it on shoes, if the user wants to take off their shoes, they only need to press the button of the lacing buckle on the right shoe with their left foot to remove their right shoe, effectively freeing their hands and eliminating the need to bend over. After releasing the button, the reset spring pushes the transmission wheel to move upward axially to return. The axially oriented triangular teeth engage with the radially oriented triangular gears through the reset spring, and thus the pressing and rotating lacing buckle returns to its initial state.

[0047] The pressing and rotating lacing buckle provided in the embodiments of the utility model is provided with a reset spring, a transmission wheel, a cap, and a button. The cap drives the take-up wheel to rotate within the take-up seat via the transmission wheel. When the button is pressed, it acts on the transmission wheel and compresses the reset spring, separating and resetting the transmission connection between the cap and the take-up wheel. This allows for switching or releasing the winding lock state of the lacing buckle simply by pressing the button, even with the feet or other ground objects, freeing up the hands and eliminating the need for bending over, thus improving the user experience.

[0048] Furthermore, the use of a one-way brake with an elastic structure ensures that the cap rotates unidirectionally under a certain force, preventing free rotation. The ratchet engagement, tooth engagement, and pin engagement results in a simple structure and a stable locking state.

[0049] Content not described in detail in this specification is related art known to those skilled in the art.

[0050] Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility model, the scope of which is defined by the appended claims and their equivalents.
