They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1 to 4 A preferred embodiment of a cyclic lifting pedal is shown, which includes a pedal support assembly 1 and a pedal body assembly 2; the pedal body assembly 2 is slidably mounted on the pedal support assembly 1.

[0028] The foot pedal support assembly 1 includes a support body 11 and a stop block 12 fixedly connected to the support body 11. In this embodiment, the support body 11 has a "U"-shaped structure, with its two arm ends connected to the seat legs. In other embodiments, the support body 11 may have other shapes and may also be connected to the seat rod. In this embodiment, the front part of the support body 11 has a hollow sliding groove 111, in which the foot pedal assembly 2 is slidably installed. The stop block 12 is fixed in the sliding groove 111. The stop block 12 is provided with a limiting structure. Specifically, in this embodiment, the stop block 12 has a recess 122, on which the limiting structure is provided. The limiting structure includes a plurality of stop grooves 121 arranged along the height direction. In this embodiment, the number of stop grooves 121 is three. The stop groove 121 is a "∠"-shaped oblique opening structure, with its upper groove surface being an oblique surface and its lower groove surface being a straight surface. Furthermore, the upper outer surface of the top gear slot and the lower outer surface of the bottom gear slot are both sloped surfaces.

[0029] The pedal body assembly 2 includes a pedal body, a movable adjustment member 23, and an elastic reset member 24. The movable adjustment member 23 can slide cyclically along the limiting structure. Specifically, the pedal body includes a pedal panel 21 and a lifting slider 22. In this embodiment, the pedal panel 21 and the lifting slider 22 are separate structures; more specifically, the pedal panel 21 is a T-shaped structure with a panel portion 211 and a hollow column portion 212, and the lifting slider 22 is fixed in the hollow column portion 212. The movable adjustment member 23 is hidden in the hollow column portion 212 of the pedal body. In this embodiment, the movable adjustment member 23 is a rotating movable member; the movable adjustment member 23 is rotatably connected between the lifting slider 22 and the hollow column portion 212 of the pedal panel 21. The elastic reset member 24 is connected between the movable adjustment member 23 and the lifting slider 22 of the pedal body. The hollow column portion 212 of the foot pedal panel 21 is fitted into the sliding groove portion 111 of the foot pedal support assembly 1. The rear side of the lifting slider 22 has a sliding recess 221, which slides with the stop block 12 in the sliding groove portion 111, so that the foot pedal main assembly 2 can move up and down in the sliding groove portion 111 of the foot pedal support assembly 1.

[0030] In this embodiment, the lifting slider 22, the movable adjustment component 23 and other structures are all hidden in the hollow column part 212 of the foot pedal body, which makes the appearance of the entire foot pedal structure more aesthetically pleasing.

[0031] The foot pedal body has an arc-shaped groove 222 on its lifting slider 22, and a locking head 231 on its movable adjusting member 23. The locking head 231 passes through the arc-shaped groove 222 and engages with the gear position groove 121. During the up-and-down movement of the foot pedal body assembly 2, the movable adjusting member 23 swings left and right relative to the foot pedal body, and the locking head 231 slides cyclically along the gear position groove 121 to achieve height adjustment and locking.

[0032] In other embodiments, the foot pedal panel 21 and the lifting slider 22 can also be designed as an integral structure.

[0033] In this embodiment, both the movable adjusting member 23 and the elastic resetting member 24 are teardrop-shaped structures.

[0034] This circulating height-adjustable footrest can be applied to study chairs; specifically, the footrest support assembly 1 of the circulating height-adjustable footrest can be connected to the chair legs or chair posts. For example... Figure 5 As shown, the foot support assembly 1 is connected to the front part of the seat leg 3.

[0035] In use, when the pedal height needs to be adjusted, the user can apply external force with their foot or hand to push the pedal main body assembly 2 upwards. The locking head 231 of the movable adjusting member 23 rotates under the action of the inclined surface of the gear slot 121. When the desired pedal height is reached, the external force is removed, and the movable adjusting member 23 resets under the action of the elastic reset member 24. After resetting, the locking head 231 of the movable adjusting member 23 is located in the middle position of the arc-shaped groove 222. At this time, the locking head 231 is locked in the gear slot 121, achieving gear locking. Thus, under the action of external force, the movable adjusting member 23 rotates and can slide along the gear slot 121 to achieve adjustment of different height gears. When the movable adjusting member 23 moves to the highest point under the action of external force, the external force is removed. The movable adjusting member 23 can swing and fall down under the action of the upper outer slope of the uppermost gear groove 121, and then slide in the gear groove 121 again under the action of external force.
