Description

Technical Field

[0001] The utility model relates to the technical field of heels, in particular to a heel capable of improving stability. Background Art

[0002] High heels are an essential accessory for women and are widely loved by young women. Existing high heels primarily have the heel and sole areas as their walking surfaces. However, high heels are typically thin, while the sole area is typically designed as a downwardly convex surface with the palm as its lowest point. This results in a very small contact surface between the front and back of the foot, like two points on a straight line. This can lead to unstable walking, body swaying, and even sprains and falls. While high heels with thick heels offer greater stability, they are also heavy and inconvenient to walk in. Furthermore, thick heels lack a certain aesthetic appeal compared to thinner heels, making them unattractive to young women.

[0003] Patent application number CN219699171U discloses a heel that can improve stability. The heel body includes a heel body with an hourglass shape, a connecting portion and a supporting portion. The supporting portion is conical and the connecting portion is inverted conical. The upper end of the supporting portion is fixedly connected to the lower end of the connecting portion. The bottom of the supporting portion is provided with an inwardly recessed mounting groove. The mounting groove is provided with a plurality of downwardly extending protrusions. The lower surface of the protrusions is flush with the lower surface of the supporting portion. The upper end of the connecting portion is provided with a connector for connecting to the shoe body, and fixing rods are provided on both sides of the connector. The utility model has a simple structure and good stability. It can prevent bending or falling when worn. It also has an attractive appearance and is popular with young women.

[0004] However, the heel of the shoe with improved stability disclosed in the patent is only connected to the shoe body through a connecting rod and a fixing rod, which makes it inconvenient to assemble and disassemble the heel, and it is impossible to replace the heels of different sizes according to usage needs, and the adaptability is general.

[0025] See also Figure 1-4 , a heel that can improve stability includes a shoe body 1 and a heel body 2, the bottom of the shoe body 1 is provided with a plugging groove 11, the top of the heel body 2 is provided with a limited rotation groove 20, and a limited rotation block 19 is rotatably installed in the limited rotation groove 20, and a plugging block 9 in a rectangular shape and adapted to the plugging groove 11 is installed on the top of the limited rotation block 19, two locking blocks 15 are slidably installed in the plugging block 9, and locking grooves 12 adapted to the locking blocks 15 are provided on the inner walls of both sides of the plugging groove 11, and a cavity 10 is provided in the plugging block 9, and a threaded rod 18 extending into the cavity 10 is convexly provided at the center position of the limited rotation groove 20, and a transmission slider 17 is slidably installed in the cavity 10, and the transmission slider 17 is threadedly connected to the threaded rod 18, and two mutually symmetrical T-shaped blocks 14 are arranged on the transmission slider 17, and the inner sides of the two locking blocks 15 are provided with T-shaped slots 13 adapted to the T-shaped blocks 14.

[0026] Through the mutual cooperation of the structures such as the plug-in block 9, the threaded rod 18, the transmission slider 17 and the locking block 15, when the heel body 2 is docked with the shoe body 1, the plug-in block 9 on the top of the heel body 2 can be inserted into the plug-in groove 11 at the bottom of the shoe body 1, and the heel body 2 can be rotated, so that the transmission slider 17 slides in the cavity 10 through the threaded engagement relationship between the threaded rod 18 and the transmission slider 17, and then the transmission slider 17 pushes the two locking blocks 15 to synchronously move away from each other and insert them into the locking groove 12 on the inner wall of the plug-in groove 11, thereby realizing the locking and fixation between the shoe body 1 and the heel body 2, facilitating the disassembly and assembly of the heel body 2, and facilitating the disassembly and replacement of the heel after the heel is worn to a certain extent, thereby greatly improving the service life of the shoe body 1.

[0027] Specifically, in this embodiment, both sides of the transmission slider 17 are inclined surfaces, and the inner sides of the two locking blocks 15 are also inclined surfaces.

[0028] Through the cooperation between the inclined surfaces on the transmission slider 17 and the inclined surfaces on the locking block 15 , when the transmission slider 17 moves along the threaded rod 18 , the two locking blocks 15 can be pushed to move horizontally to both sides.

[0029] Specifically, in this embodiment, four mutually symmetrical horizontal limit slots 16 are formed on the plug-in block 9 , and horizontal limit blocks 21 are slidably installed in the horizontal limit slots 16 . The horizontal limit blocks 21 are installed on the locking block 15 .

[0030] By the cooperation between the horizontal limiting groove 16 and the horizontal limiting block 21 , the moving direction and moving range of the locking block 15 can be limited.

[0031] Specifically, in this embodiment, the T-shaped block 14 and the T-shaped slot 13 are respectively arranged on the inclined surfaces of the transmission slider 17 and the locking block 15 .

[0032] Through the cooperation between the T-shaped block 14 and the T-shaped slot 13 , the transmission slider 17 can facilitate the two locking blocks 15 to move closer to each other.

[0033] Specifically, in this embodiment, two mutually symmetrical sliding cavities 3 are provided at the bottom of the shoe body 1, and a docking block 7 is slidably installed in the sliding cavity 3. Two mutually symmetrical docking grooves 8 that are adapted to the docking block 7 are provided at the top of the heel body 2. A compression spring 5 is arranged in the sliding cavity 3, and one end of the compression spring 5 is installed on the inner wall of the sliding cavity 3, and the other end of the compression spring 5 is installed on the docking block 7.

[0034] By cooperating with the docking block 7 and the docking groove 8, the docking block 7 can be aligned with the docking groove 8 after the heel body 2 is rotated along the shoe body 1 by a certain angle, so that the docking block 7 can be pushed into the docking groove 8 by the elastic potential energy of the compression spring 5, thereby realizing self-locking between the shoe body 1 and the heel body 2. Since the end of the docking block 7 away from the shoe body 1 is in an arc shape, it will not affect the disassembly of the heel body 2. During disassembly, it is only necessary to rotate the heel body 2 along the shoe body 1 so that the arc end of the docking block 7 and the edge of the docking groove 8 are squeezed against each other and the docking block 7 is retracted into the sliding cavity 3.

[0035] Specifically, in this embodiment, vertical limit grooves 4 are provided on both inner walls of the sliding cavity 3 , vertical limit blocks 6 are slidably arranged in the vertical limit grooves 4 , and the vertical limit blocks 6 are mounted on the docking blocks 7 .

[0036] The vertical limiting groove 4 and the vertical limiting block 6 can limit the moving direction and moving range of the docking block 7.
