Description

Technical Field

[0001] The present invention relates to the field of leather shoes, and particularly to a composite women's leather shoe. Background Art

[0002] Currently, the women's high-heel leather shoes provided on the market generally include a sole, a heel, and a vamp. The height of such women's high-heel leather shoes is fixed and cannot effectively adapt to and adjust different road conditions.

[0003] Existing women's leather shoes often design the heel to be relatively tall in order to highlight the charm of women, while ignoring that when a woman needs to walk a long distance due to environmental needs, she will often feel discomfort in her feet due to the relatively high heel. Nowadays, there are some women's leather shoes that can adjust the heel height, but they often use the plug-and-play method to change the heel height of the leather shoes, which is inconvenient to use and the adjustable height is not adjustable.

[0004] In view of this, the present invention provides a composite women's leather shoe to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a composite women's leather shoe. The specific problem to be solved by the present invention is that existing women's leather shoes often design the heel to be relatively tall in order to highlight the charm of women, while ignoring that when a woman needs to walk a long distance due to environmental needs, she will often feel discomfort in her feet due to the relatively high heel. And the existing height adjustment often uses the method of inserting and pulling out the height adjustment block, resulting in inconvenient use and non-adjustable height adjustment.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A composite women's leather shoe includes a first-stage heel. A sole is fixedly connected above the first-stage heel. A first inner groove is formed inside the first-stage heel. A second-stage heel is slidably connected to the inner surface of the lower end of the first-stage heel. A lifting mechanism is arranged inside the first inner groove;

[0008] The lifting mechanism includes an upper pressing cover, a first fixed shaft, a second fixed shaft, a third fixed shaft, a fourth fixed shaft, a fifth fixed shaft, a sixth fixed shaft, a first upper pressure rod, a second upper pressure rod, a first lower pressure rod, a second lower pressure rod, a lead screw, a left end hexagonal nut, a right end hexagonal nut, a left end cylindrical hollow ring, a right end cylindrical hollow ring, a left end I-shaped sleeve, a right end I-shaped sleeve, and a lower pressing cover. A groove is provided at the upper end of the second-stage heel. The lower surface of the lower pressing cover is fixedly connected to the inner surface of the groove. The upper end of the lower pressing cover is hinged to the lower end of the second lower pressure rod through the sixth fixed shaft. The sixth fixed shaft sequentially passes through the second lower pressure rod and the lower pressing cover and is fixedly connected to the inner wall of the second-stage heel. The upper end of the second lower pressure rod is hinged to the lower end of the second upper pressure rod through the fourth fixed shaft. The fourth fixed shaft sequentially passes through the second lower pressure rod and the second upper pressure rod and is slidably connected to the inner wall of the first-stage heel. The upper end of the second upper pressure rod is hinged to the inner side wall of the upper pressing cover through the second fixed shaft. The second fixed shaft sequentially passes through the second upper pressure rod and the upper pressing cover and is fixedly connected to the inner wall of the first-stage heel. The upper surface of the upper pressing cover is fixedly connected to the top of the inner wall of the first inner groove. Symmetrically fixed connections with the fourth fixed shaft are provided at both ends of the outer surface of the right end cylindrical hollow ring. The inner wall and the side wall of the right end cylindrical hollow ring are rotationally connected to the outer wall of the right end I-shaped sleeve. On the side of the outer wall of the right end I-shaped sleeve close to the first-stage heel, a right end hexagonal nut is fixedly connected. The right end hexagonal nut is threadedly connected to the lead screw. The lead screw sequentially passes through the left end I-shaped sleeve, the left end hexagonal nut, and the first-stage heel and is rotationally connected to the inner wall of the left end cap. The outer surface of the left end I-shaped sleeve is rotationally connected to the inner wall of the left end cylindrical hollow ring. The left outer wall of the left end I-shaped sleeve is fixedly connected to the right surface of the left end hexagonal nut. The outer wall of the left end cylindrical hollow ring is hinged to the first upper pressure rod and the first lower pressure rod through the third fixed shaft. The first upper pressure rod is hinged to the upper pressing cover through the first fixed shaft. The first lower pressure rod is hinged to the lower pressing cover through the fifth fixed shaft. The right outer wall of the left end cap is fixedly connected to the outer wall of the first-stage heel and the part penetrated by the lead screw. A knob is fixedly connected to the penetrated part at the right end of the lead screw. The lead screw is connected to the first-stage heel bearing through a bearing.

[0009] When the height of the high heels needs to be adjusted, the lifting mechanism works through a lead screw. The right half of the lead screw has a right-handed thread, and the left half of the lead screw has a left-handed thread. By using the left-end hexagonal nut and the right-end hexagonal nut in combination, the lifting work is carried out by rotating the right-side knob. When the knob rotates clockwise, it drives the lead screw to rotate. The right-end hexagonal nut drives the right-end I-shaped collar to move to the left. The right-end I-shaped collar drives the right-end cylindrical hollow ring. The right-end cylindrical hollow ring drives the second upper pressure rod and the second lower pressure rod through the fourth fixed shaft. The left-end hexagonal nut drives the left-end I-shaped collar to move to the right. The left-end I-shaped collar drives the left-end cylindrical hollow ring. The left-end cylindrical hollow ring drives the first upper pressure rod and the first lower pressure rod through the third fixed shaft. As a result, the angle between the first upper pressure rod and the second upper pressure rod becomes smaller, and the angle between the first lower pressure rod and the second lower pressure rod also becomes smaller, and the vertical height increases, so that the distance between the upper pressing cover and the lower pressing cover increases, and the second-level heel is pushed out from inside the first-level heel. When the knob rotates counterclockwise, the right-end hexagonal nut drives the right-end I-shaped collar to move to the right. The right-end I-shaped collar drives the right-end cylindrical hollow ring. The right-end cylindrical hollow ring drives the second upper pressure rod and the second lower pressure rod through the fourth fixed shaft. The left-end hexagonal nut drives the left-end I-shaped collar to move to the left. The left-end I-shaped collar drives the left-end cylindrical hollow ring. The left-end cylindrical hollow ring drives the first upper pressure rod and the first lower pressure rod through the third fixed shaft. As a result, the angle between the first upper pressure rod and the second upper pressure rod becomes larger, and the angle between the first lower pressure rod and the second lower pressure rod also becomes larger, and the vertical height decreases, so that the distance between the upper pressing cover and the lower pressing cover decreases, and the second-level heel is retracted from the outside of the first-level heel. Thus, the height of the leather shoes can be adjusted;

[0010] By adopting the first-level heel and the second-level heel and adding a lifting mechanism inside the first inner groove, the height of the leather shoes can be adjusted arbitrarily. On the one hand, it can reduce the discomfort of the feet caused by the relatively high heels when walking a long distance due to environmental requirements. On the other hand, it can be suitable for ladies with different leg heights. For example, for some women with defective legs resulting in inconsistent heights, the height can be adjusted through the present invention, thus facilitating walking. Due to the hinged connection between the first upper pressure rod and the second upper pressure rod and the upper pressing cover, and the hinged connection between the first lower pressure rod and the second lower pressure rod and the lower pressing cover, when the lady walks, each time she steps down, the hinged part has a buffering effect, which protects the mechanism and also has a buffering effect on the lady's sole, reducing the damage to the sole caused by walking in high heels;

[0011] Moreover, by using this lifting mechanism, it has a two-way supporting effect on the sole and the second-level heel, and the structure is more stable.

[0012] Preferably, the edge of the knob is provided with patterns.

[0013] When adjusting the height of the high heels, by providing patterns on the edge of the knob, the frictional force on the outer surface of the knob is increased, making it easier and more convenient to control the lifting mechanism.

[0014] Preferably, the material of the contact part between the sole and the first - stage heel is a flexible material.

[0015] During the use of this leather shoe, when the material of the contact part between the sole and the first - stage heel is a flexible material, on the one hand, during each walking process, it can reduce the direct force of the foot on the lifting mechanism when stepping on the ground each time, further enhancing the buffering effect; on the other hand, it also improves the flexibility of the sole and reduces the damage caused to the overall structure of the shoe by the lifting of the lifting mechanism.

[0016] Preferably, a groove is provided inside the front end of the sole, and a first airbag is provided on the inner wall of the groove. A groove is provided inside the rear end of the sole and above the first inner groove, and a second airbag is provided on the inner wall of the groove.

[0017] During the walking process, by providing the first airbag and the second airbag on the sole, the comfort of the sole of the leather shoe is improved.

[0018] Preferably, a ventilation hole is provided inside the sole above the first airbag, and a ventilation hole is provided on the sole. The ventilation hole is fixedly connected to the first airbag, and the upper end of the ventilation hole penetrates through the sole.

[0019] By providing the first airbag and the ventilation hole, when the foot steps down, the foot presses the first airbag, and the gas is discharged from the ventilation hole. The first airbag contracts, providing buffering to the foot and relieving the discomfort of the foot. When the foot is lifted, due to atmospheric pressure, the gas is transported from the air through the ventilation hole into the first airbag. Repeating this process can simultaneously achieve the comfort of the shoe and the ventilation condition inside the shoe.

[0020] Preferably, the material of the lead screw is an anti - deformation material.

[0021] When the lifting mechanism is in use, by setting the material of the lead screw to be an anti - deformation material, the deformation of the lead screw is avoided, enabling the lifting mechanism to work for a long time, preventing maintenance caused by the damage of the lead screw, and saving manpower and material resources.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By adopting a first-level heel and a second-level heel and adding a lifting mechanism inside the first inner groove, the height of leather shoes can be adjusted arbitrarily. On the one hand, when it is necessary to walk a relatively long distance due to environmental requirements, the discomfort of the feet caused by the relatively high heels can be reduced. On the other hand, it can be applied to ladies with different leg heights. For example, for some women with defective legs resulting in inconsistent heights, the height can be adjusted through the present invention, thus facilitating walking. Due to the hinged connection between the first upper pressure rod and the second upper pressure rod and the upper cover, and the hinged connection between the first lower pressure rod and the second lower pressure rod and the lower cover, when a lady walks, each time she steps down, the hinge has a buffering effect, protecting the mechanism, and also having a buffering effect on the lady's sole, reducing the harm to the sole when walking in high heels.

[0024] 2. By setting a first airbag and a ventilation hole, when the foot steps down, the foot presses the first airbag, and the gas is discharged from the ventilation hole. The first airbag contracts, buffering the foot and relieving the discomfort of the foot. When the foot is lifted, due to atmospheric pressure, the gas is transported from the air through the ventilation hole into the first airbag. Repeating this process can simultaneously achieve the comfort of the shoes and the ventilation condition inside the shoes. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a composite women's leather shoe, including a first-level heel 1, the upper part of the first-level heel 1 is fixedly connected with a sole 3, a first inner groove 4 is opened inside the first-level heel 1, the lower inner surface of the first-level heel 1 is slidably connected with a second-level heel 2, and a lifting mechanism 7 is arranged inside the first inner groove 4;

[0032] The lifting mechanism 7 includes an upper pressure cover 701, a first fixed shaft 702, a second fixed shaft 703, a third fixed shaft 704, a fourth fixed shaft 705, a fifth fixed shaft 706, a sixth fixed shaft 707, a first upper pressure rod 708, a second upper pressure rod 709, a first lower pressure rod 710, a second lower pressure rod 711, a lead screw 712, a left end hexagonal nut 713, a right end hexagonal nut 714, a left end cylindrical hollow ring 715, a right end cylindrical hollow ring 716, a left end I-shaped collar 717, a right end I-shaped collar 718, and a lower pressure cover 719. A groove is provided at the upper end of the second-stage heel 2, and the lower surface of the lower pressure cover 719 is fixedly connected to the inner surface of the groove. The upper end of the lower pressure cover 719 is hinged to the lower end of the second lower pressure rod 711 through the sixth fixed shaft 707. The sixth fixed shaft 707 sequentially passes through the second lower pressure rod 711 and the lower pressure cover 719 and is fixedly connected to the inner wall of the second-stage heel 2. The upper end of the second lower pressure rod 711 is hinged to the lower end of the second upper pressure rod 709 through the fourth fixed shaft 705. The fourth fixed shaft 705 sequentially passes through the second lower pressure rod 711 and the second upper pressure rod 709 and is slidably connected to the inner wall of the first-stage heel 1. The upper end of the second upper pressure rod 709 is hinged to the inner side wall of the upper pressure cover 701 through the second fixed shaft 703. The second fixed shaft 703 sequentially passes through the second upper pressure rod 709 and the upper pressure cover 701 and is fixedly connected to the inner wall of the first-stage heel 1. The upper surface of the upper pressure cover 701 is fixedly connected to the top of the inner wall of the first inner groove 4. Symmetrically fixed to both ends of the outer surface of the right end cylindrical hollow ring 716 are fourth fixed shafts 705. The inner wall and side wall of the right end cylindrical hollow ring 716 are rotationally connected to the outer wall of the right end I-shaped collar 718. Fixedly connected to the side of the outer wall of the right end I-shaped collar 718 close to the first-stage heel 1 is a right end hexagonal nut 714. The right end hexagonal nut 714 is threadedly connected to the lead screw 712. The lead screw 712 sequentially passes through the left end I-shaped collar 717, the left end hexagonal nut 713, and the first-stage heel 1 and is rotationally connected to the inner wall of the left end cap 8. The outer surface of the left end I-shaped collar 717 is rotationally connected to the inner wall of the left end cylindrical hollow ring 715. The left side outer wall of the left end I-shaped collar 717 is fixedly connected to the right surface of the left end hexagonal nut 713. The outer wall of the left end cylindrical hollow ring 715 is hinged to the first upper pressure rod 708 and the first lower pressure rod 710 through the third fixed shaft 704. The first upper pressure rod 708 is hinged to the upper pressure cover 701 through the first fixed shaft 702. The first lower pressure rod 710 is hinged to the lower pressure cover 719 through the fifth fixed shaft 706. The right side outer wall of the left end cap 8 is fixedly connected to the outer wall of the first-stage heel 1 and the part penetrated by the lead screw 712. A knob 9 is fixedly connected to the penetrated part at the right end of the lead screw 712. The lead screw 712 is connected to the first-stage heel 1 through a bearing 10 by the bearing 10.

[0033] When the height of the high heels needs to be adjusted, the lifting mechanism 7 works through the lead screw 712. The right half of the lead screw 712 has a right-handed thread, and the left half of the lead screw 712 has a left-handed thread. By using the matching of the left-end hexagon nut 713 and the right-end hexagon nut 714, the lifting work is carried out by rotating the right-side knob 9. When the knob 9 rotates clockwise, it drives the lead screw 712 to rotate. The right-end hexagon nut 714 drives the right-end I-shaped collar 718 to move leftward. The right-end I-shaped collar 718 drives the right-end cylindrical hollow ring 716. The right-end cylindrical hollow ring 716 drives the second upper pressure rod 709 and the second lower pressure rod 711 through the fourth fixed shaft 705. The left-end hexagon nut 713 drives the left-end I-shaped collar 717 to move rightward. The left-end I-shaped collar 717 drives the left-end cylindrical hollow ring 715. The left-end cylindrical hollow ring 715 drives the first upper pressure rod 708 and the first lower pressure rod 710 through the third fixed shaft 704. As a result, the angle between the first upper pressure rod 708 and the second upper pressure rod 709 becomes smaller, and the angle between the first lower pressure rod 710 and the second lower pressure rod 711 also becomes smaller. The vertical height increases, making the distance between the upper pressure cover 701 and the lower pressure cover 719 increase, and pushing the second-level heel 2 out of the first-level heel 1. When the knob 9 rotates counterclockwise, the right-end hexagon nut 714 drives the right-end I-shaped collar 718 to move rightward. The right-end I-shaped collar 718 drives the right-end cylindrical hollow ring 716. The right-end cylindrical hollow ring 716 drives the second upper pressure rod 709 and the second lower pressure rod 711 through the fourth fixed shaft 705. The left-end hexagon nut 713 drives the left-end I-shaped collar 717 to move leftward. The left-end I-shaped collar 717 drives the left-end cylindrical hollow ring 715. The left-end cylindrical hollow ring 715 drives the first upper pressure rod 708 and the first lower pressure rod 710 through the third fixed shaft 704. As a result, the angle between the first upper pressure rod 708 and the second upper pressure rod 709 becomes larger, and the angle between the first lower pressure rod 710 and the second lower pressure rod 711 also becomes larger. The vertical height decreases, making the distance between the upper pressure cover 701 and the lower pressure cover 719 decrease, and retracting the second-level heel 2 from the outside of the first-level heel 1. Thus, the adjustable height of the leather shoes is achieved;

[0034] By adopting the first-level heel 1 and the second-level heel 2 and adding a lifting mechanism 7 inside the first inner groove 4, the height of the leather shoes can be adjusted arbitrarily. On the one hand, it can reduce the discomfort of the feet caused by the relatively high heels when walking a long distance due to environmental requirements. On the other hand, it can be applicable to ladies with different leg heights. For example, for some women with defective legs resulting in inconsistent heights, the height adjustment can be achieved through the present invention, thus facilitating walking. Due to the hinged connection between the first upper pressure rod 708 and the second upper pressure rod 709 and the upper cover 701, and the hinged connection between the first lower pressure rod 710 and the second lower pressure rod 711 and the lower cover 719, when a lady walks, each time she steps down, the hinged part has a buffering effect, protecting the mechanism and also having a buffering effect on the lady's sole, reducing the harm to the sole when walking in high heels. Moreover, when using this lifting mechanism 7, it has a two-way supporting effect on the sole 3 and the second-level heel 2, making the structure more stable.

[0035] Preferably, the edge of the knob 9 is provided with patterns.

[0036] When adjusting the height of the high heels, by providing patterns on the edge of the knob 9, the frictional force on the outer surface of the knob 9 is increased, making the control of the lifting mechanism 7 easier and more convenient.

[0037] Preferably, the material of the contact part between the sole 3 and the first-level heel 1 is a flexible material.

[0038] During the use of this leather shoe, when the material of the contact part between the sole 3 and the first-level heel 1 is a flexible material, on the one hand, it can reduce the direct acting force of the foot on the lifting mechanism 7 each time when stepping on the ground, further enhancing the buffering effect. On the other hand, it also improves the flexibility of the sole 3 and reduces the harm caused by the lifting of the lifting mechanism 7 to the overall structure of the shoes.

[0039] Preferably, a groove is provided inside the front end of the sole 3, and a first airbag 5 is provided on the inner wall of the groove. A groove is provided inside the rear end of the sole 3 and above the first inner groove 4, and a second airbag 6 is provided on the inner wall of the groove. During walking, by providing the first airbag 5 and the second airbag 6 on the sole 3, the comfort of the sole 3 of the leather shoes is improved.

[0040] Preferably, a ventilation hole 11 is provided inside the sole 3 above the first airbag 5. The sole 3 is provided with the ventilation hole 11, the ventilation hole 11 is fixedly connected to the first airbag 5, and the upper end of the ventilation hole 11 penetrates through the sole 3.

[0041] By setting the first airbag 5 and the ventilation holes 11, when the foot steps down, the foot presses the first airbag 5, and the gas is discharged from the ventilation holes 11. The first airbag 5 contracts, providing cushioning for the foot and relieving discomfort in the foot. When the foot is lifted, due to atmospheric pressure, the gas is transported from the air through the ventilation holes 11 into the first airbag 5. Repeating this process can simultaneously achieve the comfort of the shoes and the ventilation condition inside the shoes.

[0042] Preferably, the material of the lead screw 712 is made of anti-deformation material.

[0043] When the lifting mechanism 7 is in use, by setting the material of the lead screw 712 to be made of anti-deformation material, deformation of the lead screw 712 is avoided, enabling the lifting mechanism 7 to work for a long time and preventing repairs caused by damage to the lead screw 712, saving manpower and material resources.

[0044] Working principle: When the height of the high heels needs to be adjusted, the lifting mechanism 7 works through the lead screw 712. The right half of the lead screw 712 has a right-handed thread, and the left half of the lead screw 712 has a left-handed thread. By using the left-end hexagonal nut 713 and the right-end hexagonal nut 714 in combination, the lifting work is carried out by rotating the right-side knob 9. When the knob 9 rotates clockwise, it drives the lead screw 712 to rotate. The right-end hexagonal nut 714 drives the right-end I-shaped collar 718 to move to the left. The right-end I-shaped collar 718 drives the right-end cylindrical hollow ring 716. The right-end cylindrical hollow ring 716 drives the second upper pressure rod 709 and the second lower pressure rod 711 through the fourth fixed shaft 705. The left-end hexagonal nut 713 drives the left-end I-shaped collar 717 to move to the right. The left-end I-shaped collar 717 drives the left-end cylindrical hollow ring 715. The left-end cylindrical hollow ring 715 drives the first upper pressure rod 708 and the first lower pressure rod 710 through the third fixed shaft 704. As a result, the angle between the first upper pressure rod 708 and the second upper pressure rod 709 becomes smaller, and the angle between the first lower pressure rod 710 and the second lower pressure rod 711 also becomes smaller. The vertical height increases, making the distance between the upper pressure cover 701 and the lower pressure cover 719 increase, and pushing the second-level heel 2 out of the first-level heel 1. When the knob 9 rotates counterclockwise, the right-end hexagonal nut 714 drives the right-end I-shaped collar 718 to move to the right. The right-end I-shaped collar 718 drives the right-end cylindrical hollow ring 716. The right-end cylindrical hollow ring 716 drives the second upper pressure rod 709 and the second lower pressure rod 711 through the fourth fixed shaft 705. The left-end hexagonal nut 713 drives the left-end I-shaped collar 717 to move to the left. The left-end I-shaped collar 717 drives the left-end cylindrical hollow ring 715. The left-end cylindrical hollow ring 715 drives the first upper pressure rod 708 and the first lower pressure rod 710 through the third fixed shaft 704. As a result, the angle between the first upper pressure rod 708 and the second upper pressure rod 709 becomes larger, and the angle between the first lower pressure rod 710 and the second lower pressure rod 711 also becomes larger. The vertical height decreases, making the distance between the upper pressure cover 701 and the lower pressure cover 719 decrease, and retracting the second-level heel 2 from the outside of the first-level heel 1. Thus, the adjustable height of the leather shoes is realized;

[0045] By adopting the first-level heel 1 and the second-level heel 2 and adding a lifting mechanism 7 inside the first inner groove 4, the height of leather shoes can be adjusted arbitrarily. On the one hand, when it is necessary to walk a relatively long distance due to environmental requirements, the discomfort of the feet caused by the relatively high heels can be reduced. On the other hand, it can be applied to ladies with different leg heights. For example, for some women with defective legs resulting in inconsistent heights, the height adjustment can be achieved through the present invention, thus facilitating walking. Due to the hinge connection between the first upper pressure rod 708 and the second upper pressure rod 709 and the upper cover 701, and the hinge connection between the first lower pressure rod 710 and the second lower pressure rod 711 and the lower cover 719, when a lady walks, each time she steps down, the hinge has a buffering effect, protecting the mechanism and also having a buffering effect on the lady's sole, reducing the harm to the sole when walking in high heels.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.

The upper end of the lower pressure cover (719) is hinged to the lower end of the second lower pressure rod (711) through the sixth fixed shaft (707). The sixth fixed shaft (707) sequentially passes through the second lower pressure rod (711) and the lower pressure cover (719) and is fixedly connected to the inner wall of the second-level heel (2). The upper end of the second lower pressure rod (711) is hinged to the lower end of the second upper pressure rod (709) through the fourth fixed shaft (705). The fourth fixed shaft (705) sequentially passes through the second lower pressure rod (711) and the second upper pressure rod (709) and is slidably connected to the inner wall of the first-level heel (1). The upper end of the second upper pressure rod (709) is hinged to the inner side wall of the upper pressure cover (701) through the second fixed shaft. The second fixed shaft sequentially passes through the second upper pressure rod (709) and the upper pressure cover (701) and is fixedly connected to the inner wall of the first-level heel (1). The upper surface of the upper pressure cover (701) is fixedly connected to the top of the inner wall of the first inner groove (4). Symmetrically fixed to both ends of the outer surface of the right-end cylindrical hollow ring (716) are fourth fixed shafts (705). The inner wall and side wall of the right-end cylindrical hollow ring (716) are rotationally connected to the outer wall of the right-end I-shaped collar (718). Fixedly connected to one side of the outer wall of the right-end I-shaped collar (718) close to the first-level heel (1) is a right-end hexagon nut (714). The right-end hexagon nut (714) is threadedly connected to the lead screw (712). The lead screw (712) sequentially passes through the left-end I-shaped collar (717), the left-end hexagon nut (713), and the first-level heel (1) and is rotationally connected to the inner wall of the left-end cap (8). The outer surface of the left-end I-shaped collar (717) is rotationally connected to the inner wall of the left-end cylindrical hollow ring (715). The left outer wall of the left-end I-shaped collar (717) is fixedly connected to the right surface of the left-end hexagon nut (713). The outer wall of the left-end cylindrical hollow ring (715) is hinged to the first upper pressure rod (708) and the first lower pressure rod (710) through the third fixed shaft. The first upper pressure rod (708) is hinged to the upper pressure cover (701) through the first fixed shaft (702). The first lower pressure rod (710) is hinged to the lower pressure cover (719) through the fifth fixed shaft (706).The outer wall on the right side of the left end cap (8) is fixedly connected to the outer wall of the first-stage heel (1) at the part penetrated by the lead screw (712). A knob (9) is fixedly connected to the penetrated part at the right end of the lead screw (712). The lead screw (712) is connected to the first-stage heel (1) through a bearing (10); the edge of the knob (9) is provided with patterns; the material of the contact part between the sole (3) and the first-stage heel (1) is a flexible material; a groove is formed inside the front end of the sole (3), and a first airbag (5) is arranged on the inner wall of the groove. A groove is formed inside the rear end of the sole (3) and above the first inner groove (4), and a second airbag (6) is arranged on the inner wall of the groove; above the first airbag (5) and inside the sole (3), there is a ventilation hole (11). The sole (3) is provided with the ventilation hole (11), and the ventilation hole (11) is fixedly connected to the first airbag (5). The upper end of the ventilation hole (11) penetrates through the sole (3); By providing the first airbag (5) and the ventilation hole (11), when the foot steps down, the foot presses the first airbag (5), and the gas is discharged from the ventilation hole (11). The first airbag (5) contracts, buffering the foot and relieving the discomfort of the foot. When the foot is lifted, due to the atmospheric pressure, the gas is transported from the air into the first airbag (5) through the ventilation hole (11). Repeating this process can simultaneously achieve the comfort of the shoes and the ventilation condition inside the shoes; the lead screw (712) is made of anti-deformation material; Due to the hinged connections of the first upper pressure rod (708) and the second upper pressure rod (709) with the upper cover (701), and the hinged connections of the first lower pressure rod (710) and the second lower pressure rod (711) with the lower cover (719), when a woman walks, each time she steps down, the hinged joints have a buffering effect, protecting the mechanism and also having a buffering effect on the soles of the woman's feet, reducing the harm to the soles when walking in high heels. Moreover, by using this lifting mechanism (7), there is a two-way supporting effect on the sole (3) and the second-stage heel (2), making the structure more stable.
