Description

Technical Field

[0001] This utility model relates to the field of high-heeled shoe technology, and in particular to a high-heeled shoe with a protective structure and a replaceable heel. Background Technology

[0002] Currently, with the continuous advancement of technology and the constant changes in consumer demand, the design and functions of interchangeable high heels will become more diverse. In the future, these shoes are expected to become one of the mainstream products in the high heel market, bringing users more choices and a better wearing experience.

[0003] Chinese Patent Application No. 201721329109.5 discloses an improved interchangeable-heel high heel shoe, comprising an upper, a fork heel, and a heel. The lower part of the upper has a midsole injection-molded from PP material, and the fork heel has a large sole plate integrally formed with the fork heel. The upper and midsole are set on the fork heel, and the upper part of the heel has a groove, through which the heel is engaged with a protrusion at the lower part of the fork heel. It also includes a first heel release button, a second heel release button, a heel pin, and a spring. The first and second heel release buttons are respectively provided with a first shaft hole and a second shaft hole with the same structure. The first shaft hole and the second shaft hole are respectively installed with a first shaft and a second shaft with the same structure. The heel pin is set inside the fork heel, which reduces the manufacturing process of the heel and lowers the cost. The right end of the heel release button extends to the outside, making it easier to remove the heel and change the heel without taking off the shoe, making it convenient to use.

[0004] The aforementioned patent describes a method for removing the heel by pressing the second heel release button at the rear. The front of the second heel release button presses down on the rear of the first heel release button, overcoming the spring force. The front of the first heel release button then causes the heel pin to disengage from the pin groove in the heel. At this point, the heel can be moved to the left to remove it. However, in actual use, these high heels may encounter various road conditions, such as when walking on stairs or when sharp objects come into contact with the second heel release button. This could cause the heel to loosen and fall off, which is very dangerous. A loose or detached heel can cause the shoe to lose stability while walking, increasing the risk of falling. To address these issues, a high heel with a protective structure and a replaceable heel is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a replaceable heel with a protective structure. By providing a protective structure, the heel effectively prevents the second heel release button from being triggered by sharp objects, thereby making the shoe more stable when walking and effectively avoiding the risk of falling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high heel with a protective structure and a replaceable heel, including a fork heel and a heel. The fork heel is provided with a protrusion, and the heel is provided with a slot for inserting into the protrusion. The fork heel is provided with a heel pin hole that penetrates the fork heel. The slot is provided with a heel pin groove corresponding to the heel pin hole. The heel pin hole is provided with a heel pin extending into the heel pin groove. The system also includes a control structure for controlling the heel pin to reciprocate in and out of the heel pin groove. The control structure includes a second heel release button that is rotatably provided. The bottom of the fork heel is provided with an exposed hole communicating with the outside. The system also includes a protective structure that restricts the rotation of the second heel release button. When the control structure controls the protrusion to be inserted into the slot, the protective structure restricts the rotation of the second heel release button.

[0007] By adopting the above technical solution and through the setting of the protective structure, the second heel release button is effectively prevented from being triggered by sharp objects, thereby making the shoe more stable when walking and effectively avoiding the risk of falling.

[0008] The second heel release button is further configured such that: the second heel release button includes a rear end corresponding to the exposed hole; the protective structure includes a knob located outside the exposed hole, a rotating shaft fixedly disposed on one side of the knob, and a rotating hole opened at the rear end of the second heel release button; the rotating shaft is rotatably disposed in the rotating hole; when the knob rotates to match its shape and size with the shape and size of the exposed hole, the second heel release button is rotated; otherwise, the rotation of the second heel release button is restricted; and there is an installation structure between the knob and the second heel release button.

[0009] By adopting the above technical solution, a knob is set and located outside the exposed hole for easy user operation; the knob is rotatably set inside the rotating hole via a rotating shaft, providing a rotation axis; the knob is operated by rotating, which is simple. When its shape and size match the shape and size of the exposed hole, the knob is driven in and out of the exposed hole by the second heel release knob. Then, through the linkage control of the control structure, which is existing technology, the specific structure and principle of the control structure are explained in detail in the specific implementation, and will not be elaborated on here. The control structure enables the second heel release knob to rotate and drive the heel pin to reciprocate in and out of the heel pin groove for heel replacement.

[0010] The knob and the exposed hole are further configured such that their cross-sections are both elliptical.

[0011] By adopting the above technical solution, and by setting both the knob and the exposed hole to have an elliptical cross-section, the processing is simple and the manufacturing cost is low.

[0012] Further configured as follows: the mounting structure includes a storage groove opened at the rear end of the second unmount button and passing through the rotating hole; a connecting ball is fixedly provided at one end of the rotating shaft that enters the storage groove; a snap-fit ​​sleeve is snapped onto the connecting ball; and an installation port communicating with the outside is provided on the side of the snap-fit ​​sleeve opposite to the connecting ball. The maximum diameter of the snap-fit ​​sleeve is greater than the maximum diameter of the rotating hole.

[0013] By adopting the above technical solution, through the setting of the snap-fit ​​sleeve and the connecting ball, and with the maximum diameter of the snap-fit ​​sleeve being larger than the maximum diameter of the rotating hole, the snap-fit ​​sleeve snaps the connecting ball into the storage groove, ensuring that the knob will not fall off; the snap-fit ​​sleeve snapping onto the connecting ball makes assembly simple and quick, reducing labor costs during assembly; the setting of the installation port provides operating space for the snap-fit ​​sleeve to snap onto the connecting ball, facilitating the assembly of the two; the setting of the storage groove facilitates the storage of the snap-fit ​​sleeve, reducing the space occupied.

[0014] The device is further configured such that: a first spring is fitted on the rotating shaft, and the two ends of the first spring abut against the inner wall of the storage groove and the snap-fit ​​sleeve respectively; anti-slip textures are provided on the side of the knob and the fork facing each other; when the knob is rotated so that its shape and size do not match the shape and size of the exposed hole, the first spring drives the two anti-slip textures to press against each other.

[0015] By adopting the above technical solution, and through the setting of the first spring and anti-slip texture, when the knob rotates and its shape and size do not match the shape and size of the exposed hole, the knob is located outside the exposed hole. The first spring will be compressed by the squeezing between the snap sleeve and the storage groove, thereby generating a restoring force. Under the action of the restoring force, the two anti-slip textures will be driven to press against each other, increasing the friction when the knob rotates, and more effectively preventing the knob from being accidentally triggered by rotation, making the protection more effective. Its structure is simple and the manufacturing cost is low. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] refer to Figures 1 to 5 A high heel with a replaceable heel and a protective structure includes a fork heel 1 and a heel 2. A protrusion 11 is fixedly provided at the lower end of the fork heel 1. A slot 21 is provided at the top of the heel 2, which is inserted into the protrusion 11. A heel pin hole 12 is provided inside the fork heel 1, and a heel pin groove 22 corresponding to the heel pin hole 12 is provided in the slot 21. A heel pin 3 extending into the heel pin groove 22 is provided in the heel pin hole 12. The shoe also includes a control structure for controlling the reciprocating movement of the heel pin 3 in and out of the heel pin groove 22. The control structure includes a second heel release button 4 and a first heel release button 8 rotatably mounted on the fork heel 1. A second shaft 44 is rotatably mounted on the second heel release button 4. The first heel release button 8... The button 8 is rotatably provided with a first shaft 84. The fork heel 1 is also provided with a fixing groove 92 for fixing the first shaft 84 and the second shaft 44. Each fixing groove 92 is provided with a fixing block 9 that restricts the first shaft 84 and the second shaft 44. Each fixing block 9 corresponds to the two ends of the second shaft 44 and the first shaft 84. Each fixing block 9 is provided with a screw 91 that fixes the shaft in the fixing groove 92. The bottom of the fork heel 1 is provided with an exposed hole 13 that communicates with the outside. It includes a protective structure that restricts the rotation of the second heel release button 4. When the control structure controls the protrusion 11 to be inserted into the slot 21, the protective structure restricts the rotation of the second heel release button 4.

[0024] The first heel release button 8 includes a rear end 81 and a front end 82. A second spring 83 is provided below the rear end 81. The second heel release button 4 includes a rear end 41 and a front end. The front end 82 is engaged with the upper end of the heel pin 3. The rear end 41 corresponds to the exposed hole 13. The protective structure includes a knob 5 located outside the exposed hole 13, a rotating shaft 51 integrally formed on one side of the knob 5, and a rotating hole 411 opened at the rear end 41 of the second heel release button. The rotating shaft 51 is rotatably disposed in the rotating hole 411. When the knob 5 rotates so that its shape and size match the shape and size of the exposed hole 13, the second heel release button 4 rotates. Conversely, it restricts the rotation of the second heel release button 4. There is an installation structure between the knob 5 and the second heel release button 4. The cross-sections of both the knob 5 and the exposed hole 13 are elliptical.

[0025] The mounting structure includes a storage groove 43 located at the rear end of the second unmount button 4 and passing through the rotating hole 411; a connecting ball 52 integrally formed at one end of the rotating shaft 51 that enters the storage groove 43; a snap-fit ​​sleeve 6 that snaps onto the connecting ball 52; and an installation port 431 located on the side of the snap-fit ​​sleeve 6 opposite to the connecting ball 52 that communicates with the outside. The maximum diameter of the snap-fit ​​sleeve 6 is larger than the maximum diameter of the rotating hole 411, and the maximum diameter of the connecting ball 52 is smaller than the maximum diameter of the rotating hole 411, which facilitates the installation of the rotating button 5. The materials of the heel pin 3, the first unmount button 8, the second unmount button 4, the rotating button 5, the rotating shaft 51, the snap-fit ​​sleeve 6, and the connecting ball 52 are all zinc alloy. Zinc alloy has high strength and hardness, can withstand greater external impact and pressure, and is not easily deformed or damaged.

[0026] A first spring 7 is fitted on the pivot 51. The two ends of the first spring 7 abut against the inner wall of the storage groove 43 and the snap sleeve 6, respectively. The knob 5 and the fork heel 1 are integrally formed with anti-slip textures 53 on the opposite sides. When the knob 5 is rotated so that its shape and size do not match the shape and size of the exposed hole 13, the first spring 7 drives the two anti-slip textures 53 to press against each other, increasing the friction when the knob 5 is rotated, and more effectively preventing the knob 5 from being accidentally rotated and triggered.

[0027] The entire operation process is as follows: When disassembling the heel 2, the operator rotates the knob 5 by hand. When the oval knob 5 is rotated so that its shape and size match the exposed hole 13, the operator pushes the knob 5 into the exposed hole 13 by hand, driving the rotation of the second heel release knob 4. After the front end 42 of the second heel release knob presses down on the first heel release knob, it overcomes the elastic force of the second spring 83. The front end 82 of the first heel release knob drives the heel pin 3 to move upward, causing the heel pin 3 to disengage from the heel pin groove 22 of the heel 2. At this time, the heel 2 is moved to the left. The heel can be removed to facilitate the replacement of the heel 2. When installing the heel 2, the heel 2 moves to the right, and the protrusion 11 is inserted into the slot 21. The operator pulls the knob 5 out of the exposed hole 13 by hand, and then rotates the knob 5 so that the shape and size of the knob 5 and the exposed hole 13 do not match. The second spring 83 is compressed and the restoring force will drive the rear end 81 of the first heel removal knob to rise. The front end 82 of the first heel removal knob drives the heel pin 3 to move downward, so that the heel pin 3 is inserted into the heel pin groove 22 of the heel 2, thereby installing the heel 2.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
