[0042] The thrust ring 801 is sleeved between the front cylinder tube 401 and the rear cylinder tube 402 in the cylinder part 4, and can rotate relative to the cylinder shell and reciprocate with the cylinder shell.

[0043] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 6

[0044] See also Figure 1-8 The oil cylinder part 4 includes an oil cylinder front tube 401, an oil cylinder rear tube 402, a guide rod 403, a fixing block 404, a piston 405, a pipe joint 406 and a nut 407; One end of the piston 405 is fastened to the hole of the fixed block 404 by a nut 407, and the fixed block 404 is welded to the base plate 2; two pipe joints 406 are provided, which are fixedly installed on the fixed block 404 and are respectively connected to the high-pressure oil hole and the low-pressure oil hole inside the piston 405; the front tube 401 of the cylinder and the rear tube 402 of the cylinder are respectively inserted into the piston 405 and fixed with threads to form a cylinder shell, and the cylinder shell reciprocates and rotates relative to the piston 405, wherein the front tube 401 of the cylinder and the piston 405 are sealed with a sealing ring; the guide control rod 403 is fixedly installed on the side wall of one end of the rear tube 402 of the cylinder, and one end of the guide control rod is inserted into the circular frame plate 103 below the control pedal 101, and the guide control rod 403 controls the rotation of the cylinder shell as the control pedal 101 moves up and down.

[0045] Furthermore, in the present embodiment, a first circulation groove 408 and a second circulation groove 412 are provided at one end of the piston 405, and a piston low-pressure groove 409 and a piston high-pressure groove 410 are also provided at the other end, and a communication groove 411 corresponding to the position of the piston low-pressure groove 409 and the piston high-pressure groove 410 is provided on the cylinder front tube 401; through the setting of the above-mentioned grooves, different circulation circuits of high-pressure oil can be formed, and at the same time, the piston low-pressure groove 409 or the piston high-pressure groove 410 and the communication groove 411 can be interconnected or closed in coordination with the rotation of the cylinder shell, thereby realizing the telescopic movement of the cylinder shell.

[0046] Specifically, when using Figure 7-8 As shown, when the oil cylinder housing moves toward the fixed block 404, the communication groove 411 on the oil cylinder rear pipe 402 is connected with the piston low-pressure groove 409 and the second flow groove 412 on the piston 405; At this time, the high-pressure oil in the system enters the oil chamber A9 through the pipe joint 406 at the high-pressure end and the first flow groove 408 opened inside the piston 405, so that the high-pressure oil squeezes the annular walls on both sides of the oil chamber 1. Since the left annular wall belongs to the side wall of the fixed piston 405, the high-pressure oil can only squeeze the annular wall belonging to the front tube 401 of the oil cylinder, pushing the oil cylinder to move to the right; When the oil cylinder moves to the right, the oil in the oil chamber C11 is squeezed into the oil chamber B10 through the piston low-pressure groove 409 and the communication groove 411, and then returns to the inside of the piston 405 through the second flow groove 412, and then returns to the pipe joint 406 at the low-pressure end, and then returns to the oil tank connected to the pipe joint 406; That is, the oil cylinder housing will keep moving to the right until the left side of the oil cylinder housing hits the right side of the piston and the volume of the oil chamber C11 becomes 0. At this time, the guide rod 403 is in the original position.

[0047] When the control rod 403 is rotated by pressure, the cylinder housing is fixedly connected to the control rod 403, so the cylinder housing also rotates. Due to the rotation of the cylinder housing, the communication groove 411 on the cylinder rear tube 402 rotates and communicates with the piston high-pressure groove 410, and the piston low-pressure groove 409 is closed. At this time, the high-pressure oil of the system enters not only the oil chamber A9 but also the oil chamber C11. Due to the volume of the piston in the oil chamber A9, the force-bearing area of ​​the oil chamber A9 is smaller than that of the oil chamber C11. The thrust to the right of the cylinder caused by the high-pressure oil in the oil chamber A9 is smaller than the thrust to the left of the cylinder caused by the high-pressure oil in the oil chamber C11. The cylinder moves to the right, and the high-pressure oil enters the oil chamber C11, while the high-pressure oil in the oil chamber 1 is squeezed out. Since the volume of the oil chamber B10 remains unchanged, there is neither oil flowing in nor out of the oil chamber B10.

[0048] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.

[0049] The working principle and specific use process of the hydraulic power-assist shoes: The hydraulic power shoe is initially in a horizontal state and in a balanced position. When the forefoot of a person steps on the control pedal 101, the guide rod 403 is inserted into the return frame 103 below the control pedal 101, and the guide rod 403 moves downward with the control pedal 101. The downward movement of the guide rod 403 will drive the cylinder shell of the cylinder part 4 to rotate. At this time, the cylinder begins to move to the left. The thrust ring 801 is installed between the cylinder front tube 401 and the cylinder rear tube 402, and can rotate relative to the cylinder shell, that is, it remains stationary, so the thrust ring 801 will move to the left with the cylinder shell but will not rotate with it.

[0050] Therefore, when the control pedal 101 is under force, the thrust ring 801 moves to the left driven by the cylinder housing, and the bearing 803 on the fixed shaft 802 of the thrust ring 801 pushes the bent hinge 6 as the thrust ring 801 moves to the left. The rotational movement of the bent hinge 6 is converted into the rotational movement of the rotating plate 301 and the side plate 302 through cooperation with the short hinge 5. As the cylinder housing moves to the leftmost side, the rotating plate 301 rotates to the highest point.

[0051] When a person's heel steps on the rotating plate 301, the control pedal 101 is no longer subjected to downward force and moves upward under the action of the four return springs 102, driving the guide rod 403 to move upward, causing the cylinder housing to rotate in the opposite direction and start to move back until it returns to its original position. The rotating plate 301 then rotates in the opposite direction and returns to its original horizontal position.

[0052] It should be noted that although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures, equivalent processes or equivalent functional transformations made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
