[0035] See Figure 1-16 As shown in the figure, as an embodiment of the present invention, a footrest stool is provided, including two left-right cross-hinged support members 2, and a pad post 15 is installed between the hinge axes of the two left-right cross-hinged support members 2 to ensure a cushioning effect. The support member 2 includes a front leg tube 21, a rear leg tube 22, and a connecting tube 23 located between the front leg tube 21 and the rear leg tube 22. A seat cushion 1 is installed between the connecting tubes 23 of the two support members 2. The front leg tubes 21 of the two support members 2 are left-right cross-hinged, and the rear leg tubes 22 of the two support members 2 are left-right cross-hinged. The front leg tubes 21 on the two support members 2 are telescopic tubes with adjustable height, and the rear leg tubes 22 on the two support members 2 are fixed tubes with fixed height, thereby realizing the adjustment of the footrest angle of the footrest stool, that is, realizing the adjustment of the tilt angle of the seat cushion 1, thus adapting to different types of chairs. At the same time, the footrest stool can also be used as an independent stool for users to sit on, with better versatility and meeting the user's needs in different scenarios. Furthermore, the footstool can be folded left and right, taking up little space, and is easy to assemble, disassemble, and use, making it convenient for storage or carrying.

[0036] Of course, in other cases, it is also possible for both the front leg tubes 21 and the rear leg tubes 22 on the two support members 2 to be telescopic tubes with adjustable height. This not only allows for adjustment of the footrest angle (i.e., the tilt angle of the seat cushion 1), but also allows for adjustment of the height of the seat cushion 1, resulting in better versatility and greater adaptability to different types of chairs, further meeting the user's needs in different scenarios. Similarly, it is also possible for the rear leg tubes 22 on the two support members 2 to be telescopic tubes with adjustable height, while the front leg tubes 21 on the two support members 2 are fixed-height tubes.

[0037] In this embodiment, the front leg tube 21, the rear leg tube 22 and the connecting tube 23 are integrally formed, and the connecting tube 23 is located between the top end of the front leg tube 21 and the top end of the rear leg tube 22. Of course, in other cases, the front leg tube 21, the rear leg tube 22 and the connecting tube 23 can also be separately formed.

[0038] In this embodiment, the front leg tube 21 includes an outer tube 211 and an inner tube 212 that is slidably telescopically disposed below the inner part of the outer tube 211. A positioning seat 4 is fixedly sleeved on the bottom end of the outer tube 211. Specifically, two sides of the bottom end of the outer tube 211 are respectively provided with a locking structure, so that the positioning seat 4 can stably fix the bottom end of the outer tube 211. A lever 5 is swayingly disposed on the positioning seat 4. The two ends of the lever 5 are respectively provided with an unlocking pressing part 6 and a locking positioning part 7. An elastic element 8 is installed between the unlocking pressing part 6 and the positioning seat 4. The elastic element 8 is specifically a spring. The locking positioning part 7 and the inner tube 212 are tightly fitted together to fix the inner tube 212 on the outer tube 211. Specifically, the locking and positioning part 7 is provided with an arc-shaped locking tooth 71 on the side near the inner tube 212, and a limiting groove 9 is provided on the outer wall of the inner tube 212 near the locking and positioning part 7. The extending direction of the limiting groove 9 is the same as the axial direction of the inner tube 212. The arc-shaped locking tooth 71 and the limiting groove 9 are tightly engaged to fix the inner tube 212 on the outer tube 211. In the initial state, under the elastic force of the spring, the top end of lever 5 moves outward and the bottom end moves inward, causing the arc-shaped locking tooth 71 to abut against the limiting groove 9, thereby fixing the inner tube 212 onto the outer tube 211. When it is necessary to adjust the footrest angle, press the unlocking press 6, causing the top end of lever 5 to move inward and the bottom end to move outward, compressing the spring and releasing the abutment between the arc-shaped locking tooth 71 and the limiting groove 9. This allows the inner tube 212 to slide and extend relative to the outer tube 211 to adjust its height. After the adjusted height is determined, release the unlocking press 6, the spring elastically returns to its original state, and all components return to their initial state. The arc-shaped locking tooth 71 and the limiting groove 9 then abut against each other again, thus fixing the inner tube 212 onto the outer tube 211. The arc-shaped locking tooth 71 makes the fixing and limiting effect of the inner tube 212 on the outer tube 211 more stable and reliable.

[0039] In this embodiment, the bottom end of the lever 5 is provided with a receiving groove 51, and the arc-shaped locking tooth 71 is fixedly installed in the receiving groove 51 by a pin, thereby ensuring the installation stability of the arc-shaped locking tooth 71.

[0040] In this embodiment, the positioning seat 4 has a through hole 41 through which the inner tube 212 passes. The inner tube 212 is blocked and confined within the through hole 41 of the positioning seat 4 by a pop rivet to prevent the inner tube 212 from slipping out of the positioning seat 4 and the outer tube 211. The rear leg tube 22 is equipped with an inner liner tube 10, thereby improving the structural strength and support stability of the rear leg tube 22.

[0041] In this embodiment, the width of the limiting groove 9 corresponds to the width of the arc-shaped locking tooth 71 to prevent the inner tube 212 from rotating and to ensure the stability of the limiting position.

[0042] In this embodiment, a pressing plate 11 is formed on the outer side of the unlocking pressing part 6 extending upward. A pressing concave surface 111 is formed on the upper surface of the pressing plate 11. The pressing concave surface 111 is elliptical, which fits the finger better to ensure comfort. Multiple V-shaped ridges 112 are provided in the pressing concave surface 111 to achieve a better anti-slip effect, making the pressing operation more comfortable and stable and reliable.

[0043] In this embodiment, foot pads are installed at the bottom ends of the front leg tube 21 and the rear leg tube 22. Specifically, the foot pad includes a foot pad body 13 and a foot pad plug 14. The foot pad plug 14 is fixedly installed at the bottom ends of the front leg tube 21 and the rear leg tube 22. The foot pad plug 14 has a ball part 141. A spherical groove 131 is provided in the foot pad body 13. The ball part 141 is rotatably installed in the spherical groove 131 by a rivet to realize the angle adjustment of the foot pad body 13, so as to make corresponding adjustments according to different ground conditions.

[0044] In this embodiment, two support rods 3 are also included. One end of one support rod 3 is bent to form a blocking part 31, which is used to block and limit the other support rod 3. The opposite ends of the two support rods 3 are hinged together, and the back ends of the two support rods 3 are respectively hinged to two rear leg tubes 22. When the footrest is unfolded, the two support rods 3 unfold to the left and right sides to be in a horizontal support state, ensuring the stability of the unfolded support. When the footrest is folded, the two support rods 3 fold relative to each other, reducing the space occupied. In this embodiment, the seat cushion 1 is a cloth seat cushion. The front and rear ends of the cloth seat cushion are provided with sleeve holes for the connecting tube 23 to pass through. After the cloth seat cushion is inserted into the connecting tube 23 of the two support members 2 through the sleeve holes, it is fixed by a pop rivet.

[0045] The footrest of this utility model can be unfolded to achieve two states: high angle and low angle for use. like Figure 3-5 As shown, the footrest is unfolded to a high angle: Press down the unlocking press 6 to release the arc-shaped locking tooth 71 from the limiting groove 9, pull the inner tube 212 out from the outer tube 211 to the corresponding position, and then release the unlocking press 6. The arc-shaped locking tooth 71 will then be tightly engaged with the limiting groove 9. At this time, the footrest can be adjusted to a high angle. like Figure 6-8 As shown, the footrest is in a low-angle state when unfolded: Press down the unlocking press 6 to release the arc-shaped locking tooth 71 from the limiting groove 9, push the inner tube 212 into the outer tube 211 to the corresponding position, and then release the unlocking press 6. The arc-shaped locking tooth 71 will then be in a tight fit with the limiting groove 9. At this time, the footrest can be adjusted to a low-angle state.

[0046] Compared with existing footrests, this utility model footrest is foldable and adjustable in angle. It occupies a small volume and is lightweight when folded, making it easy to store and carry. It can be adapted to different types of chairs. At the same time, this footrest can also be used as an independent stool for users to sit on, making it more versatile and meeting the needs of users in different scenarios.
