[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] This utility model embodiment provides an omnidirectional shoe expander, such as Figures 1-11 As shown, the omnidirectional shoe expander includes:

[0035] The base component and the outer expansion component include the ankle housing 3, the main adjustment rod fixing housing 7 and the housing fixing cover 13. The outer expansion component includes the heel elongated half-shell 20, the enlarged left housing 9 and the enlarged right housing 10 respectively disposed on both sides of the main adjustment rod fixing housing 7, and the lifting piece 4 disposed on the top of the main adjustment rod fixing housing 7.

[0036] The adjusting component includes a nested first grip 1 and a second grip 2 for deflecting the heel elongated half shell 20, a main adjusting rod 12 and a pusher wedge 11 connected to the main adjusting rod 12. The first grip 1 rotates and pushes the main adjusting rod 12. The main adjusting rod 12 is provided with a lifting plate top plate 121 that is raised by the pusher lifting plate 4. The pusher wedge 11 acts to enlarge the left shell position 9 and the right shell position 10 when the main adjusting rod 12 pushes forward.

[0037] The ankle housing 3 and the heel elongated half-shell 20 are connected to form a first operating cavity. The second grip 2 is nested outside the first grip 1. The first grip 1 and the second grip 2 are provided with an operating hole extending from the top of the first operating cavity to the first operating cavity. The ankle housing 3 is provided with a positioning member 21 for assembling the first grip 1. The positioning member 21 is provided with a screw hole for accommodating the first grip 1. The second grip 2 is also provided with a limiting ring. The end of the second grip 2 abuts against the positioning member 21. The limiting ring abuts against the inside of the operating hole. Under the limiting action, the second grip 2 can only rotate outside the first grip 1.

[0038] The heel extension half-shell 20 and the ankle housing 3 are connected by a shaft hole and a shaft seat. The shaft hole and shaft seat are positioned on the side of the ankle housing 3 away from the main adjusting rod fixing housing 7. The outer wall of the second grip 2 between the limiting ring and the positioning member 21 is threaded. The second grip 2 is also provided with an extension slider 22 for supporting the heel extension half-shell 20. The extension slider 22 is engaged with the thread on the outer wall of the second grip 2. When the second grip 2 rotates under the limiting action, the... The elongated slider 22 moves along the rotation axis of the second grip 2. The elongated slider 22 adopts an inclined structure. When the elongated slider 22 moves away from the axle seat, it will push the heel elongated half shell 20 to deflect around the axle seat on the ankle position 3 and make the elongated half shell 20 move away from the ankle position 3. Specifically, the heel elongated half shell 20 and the ankle position 3 are also provided with an elongated return spring 18 for connecting the elongated half shell 20 and the ankle position 3 on the side away from the axle seat.

[0039] The main adjusting rod fixing shell 7 and the shell fixing cover 13 are connected internally to form a second operating cavity. The push wedge 11 and the main adjusting rod 12 slide in the second operating cavity. The main adjusting rod fixing shell 7 has a support 74 on the side away from the push wedge 11. The support 74 extends through the ankle position shell 3 to the first operating cavity. The first operating cavity has a push plate rotating shaft 17, which is inserted into the support 74. The side wall of the main adjusting rod fixing shell 7 between the support 74 also has a deflection port 704. The push plate rotating shaft 17 has a crescent-shaped push plate 16. The propulsion plate 16 extends through the support 74 and through the deflection port 704 to the second operating cavity. The part of the propulsion plate 16 extending into the second operating cavity abuts against the end of the main adjusting rod 12 away from the propulsion wedge 11. The end of the first grip 1 is provided with a propulsion bearing disk 19. The propulsion bearing disk 19 is in contact with the part of the propulsion plate 16 located in the first operating cavity. The propulsion plate rotation shaft 17 is nested with the propulsion plate 16. When the propulsion bearing disk 19 rotates and presses down on the first grip 1, the propulsion plate 16 will move downward and deflect, thereby producing a forward pushing effect on the main adjusting rod 12.

[0040] The main adjusting rod 12 is equipped with a lifting plate 121 and a wedge push rod 122. The push wedge 11 has a receiving hole for inserting the main adjusting rod 12. When the main adjusting rod 12 rotates, the wedge push rod 122 abuts against the end face of the push wedge 11 to prevent the main adjusting rod 12 from going deep into the receiving hole, thereby synchronously pushing the push wedge 11 to move synchronously. During the forward movement of the push wedge 11, the enlarged left shell position 9 and the enlarged right shell position 10 are deflected away from the main adjusting rod fixed shell. 7; When the wedge push rod 122 no longer abuts against the end face of the push wedge 11 after rotation, but is inserted into the push wedge 11 synchronously with the main adjusting rod 12, the forward movement of the main adjusting rod 12 will no longer cause the push wedge 11 to move. After rotation, the main adjusting rod 12 is provided with a lifting plate top plate 121 that contacts and connects with the height adjustment plate 23. As the main adjusting rod 12 pushes forward, the lifting plate top plate 121 pushes the height adjustment plate 23 and the lifting plate 4 away from the lifting plate receiving groove 70.

[0041] In this embodiment, the lifting plate 4, the enlarged left shell position 9, and the enlarged right shell position 10 can respectively achieve the lifting and widening effects under the action of the main adjusting rod 12, meet different support needs, and thus expand the functionality of the omnidirectional shoe expander.

[0042] As a preferred embodiment of this example, the main adjusting rod fixing shell 7 is provided with two sets of side mounting slots. The enlarged left shell position 9 and the enlarged right shell position 10 are respectively assembled in different side mounting slots. The side mounting slots include a receiving port 701 and a rotating shaft port 702. The rotating shaft port 702 is provided with an enlarged rotating shaft 72.

[0043] In this embodiment, taking the left shell position 9 as an example, the end of the enlarged left shell position 9 is provided with a shaft plate with a rotating shaft hole. The shaft plate is nested on the widening rotating shaft 72 through the rotating shaft hole. A coil spring 8 is also provided between the shaft plate and the widening rotating shaft 72 to help the enlarged left shell position 9 reset. The end of the enlarged left shell position 9 away from the widening rotating shaft 72 is provided with a push plate. The push plate extends into the second operating cavity through the receiving port 701. The inclined structure of the side wall of the push wedge 11 is in contact with the push plate. The end face of the push plate is provided with a sliding groove. The sliding guide groove helps to limit the push wedge 11 and ensure the linearity of the sliding process. The two contact surfaces are inclined to the direction of movement of the push wedge 11, which can generate thrust when the push wedge 11 moves forward, causing the enlarged left shell position 9 to deflect away from the receiving port 701 around the widening rotating shaft 72. The enlarged right shell position 10 adopts the same design.

[0044] In a preferred embodiment of this invention, the second operating cavity is provided with a pressure plate 71 for limiting the propulsion wedge 11. The pressure plate 71 is located on the side of the main adjusting rod fixing shell 7 away from the ankle position shell 3. Near the pressure plate 71, there is also a lifting plate rotating shaft 5. Below the lifting plate 4, there is a lifting shaft seat that is nested and rotatably connected to the lifting plate rotating shaft 5. On the side of the lifting plate 4 where the lifting shaft seat is located, there is also a lifting plate return spring 6 that is elastically connected to the shell fixing cover 13. When the lifting plate... When there is no force on the side away from the rotating shaft 5 of the lifting plate, the lifting plate 4 is supported by the lifting plate return spring 6 and fits against the inner side of the lifting plate receiving groove 703. When the lifting plate 23 provided on the side away from the rotating shaft 5 of the lifting plate 4 comes into contact with the top plate 121 of the lifting plate, as the main adjusting rod 12 pushes in, the lifting plate 4 will deflect around the rotating shaft 5 and move away from the lifting plate receiving groove 703 due to the action of the inclined lifting plate 23 and the top plate 121.

[0045] In this embodiment, a partition 73 is also provided in the second operating cavity. The main adjusting rod 12 passes through the partition 73. A return spring 14 is provided on the main adjusting rod 12. The return spring 14 abuts against the end face of the partition 73 away from the push wedge 11. After the push plate 16 loses the pressure of the push bearing disk 19, the return spring 14 pushes the main adjusting rod 12 back away from the push wedge 11. A spring limiting ring is provided on the end face of the main adjusting rod 12 away from the push wedge 11. The restoring force of the return spring 14 acts on the spring limiting ring.

[0046] In a preferred embodiment of this invention, the bottom of the housing fixing cover 13 is provided with a toggle port 705, which is connected to the second operating cavity. The main adjusting rod 12 is provided with a toggle piece 123 extending from the toggle port 705 into the second operating cavity.

[0047] In this embodiment, the raised top plate 121, the wedge push rod 122, and the paddle 123 need to be arranged in a staggered manner.
