[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1-11 As shown, a multifunctional crutch stool includes a limit block 2, on which a first support leg 1 and two second support legs 3 are movably connected and can form a tripod structure as a whole after being unfolded. In this example, the limit block 2 has a triangular structure, but is not limited to a triangular structure in practice. A square, disc or other block structure can be used. The limit block 2 is provided with a mounting hole 201 for mounting the first support leg 1 and the second support leg 3, wherein the structure of the mounting hole 201 is as shown in FIG. Figure 4-6 As shown, it can meet the requirement of vertical connection of the supporting feet relative to the limit block 2, and can also meet the requirement of tilting the supporting feet relative to the limit block 2, so that when the supporting feet are in a vertical state, the three supporting feet are in a closed state, and in an inclined state, the three supporting feet are in a triangular unfolded shape. The three supporting feet are connected to the limit block 2 by pins, which will not be elaborated here.

[0036] The first supporting foot 1 is slidably and rotatably connected to a main board 9. Specifically, a transmission block 8 is sleeved on the first supporting foot 1, and the transmission block 8 is rotatably connected to the main board 9. More specifically, a connecting pin 15 with limited extension is installed on the side of the transmission block 8, and pins 16 are provided on both sides of the connecting pin 15. The two pins 16 are rotatably installed on the back side of the main board 9, so that the main board 9 and the transmission block 8 can be rotatably matched.

[0037] Sub-plates 10 are rotatably connected to both sides of the main plate 9, and the two sub-plates 10 are respectively hinged to the main plate 9 by connecting shafts, so that the sub-plates 10 have the freedom to rotate relative to the main plate 9. An elastic traction rope 7 with the upper end fixed on the sub-plate 10 is provided inside the two second supporting feet 3, wherein the upper ends of the two second supporting feet 3 are hemispherical structures, and a supporting groove 11 matching the hemispherical structure is provided on the back of the sub-plate 10, so that the ends of the two second supporting feet 3 can rotate relative to the sub-plate 10, and the upper end of the elastic traction rope 7 is fixed at the position of the supporting groove 11. In this example, the elastic traction rope 7 passes through the small hole opened inside the supporting groove 11 and is connected to the end cover outside the supporting groove 11. With such a configuration, when the second supporting feet 3 are closed or unfolded, the traction rope 7 can be used to drive the two sub-plates 10 to move, so as to achieve the effect of unfolding or folding.

[0038] When the tripod structure is unfolded, the two second supporting legs 3 unfold the two sub-plates 10 relative to the main plate 9, so that the crutch stool forms a stool structure. When the tripod structure is folded, the elastic traction rope 7 can drive the two sub-plates 10 to fold relative to the main plate 9.

[0039] Specifically, a positioning block 5 for limiting the position of the transmission block 8 is fixedly provided in the middle of the first supporting foot 1. When in use, the transmission block 8 is located above the positioning block 5. When the transmission block 8 contacts the positioning block 5, the transmission block 8 moves to the lower limit position. At this time, the main board 9 is in a horizontal state, and the user can sit on the stool and limit the position through the positioning block 5.

[0040] Specifically, it also includes a short supporting foot 6 connected to the middle part of the limit block 2, an elastic traction rope 7 is arranged inside the short supporting foot 6, and the upper end of the elastic traction rope 7 is connected to the side of the main board 9 away from the transmission block 8. Since the main board 9 and the transmission block 8 are rotatably matched, after the two second supporting feet 3 support the two sub-boards 10, the end of the main board 9 away from the first supporting foot 1 is not supported. Therefore, the short supporting foot 6 is used as a supporting member at the far end of the main board 9 to ensure the structural stability of the main board 9, wherein both ends of the short supporting foot 6 are The hemispherical structure has a lower end that cooperates with the hemispherical hole 202 opened in the middle of the limit block 2, so that the short support foot 6 can be rotated relative to the limit block 2. The upper end of the short support foot 6 is also a hemispherical structure, which cooperates with the hemispherical support groove 11 on the back of the main board 9. Furthermore, the elastic traction rope 7 is used to pass through the upper and lower hemispherical holes 202 and the support groove 11 and then fix them respectively, so that after the two second support feet 3 are unfolded or merged, the short support foot 6 can also be unfolded or merged under the linkage action of the elastic traction rope 7.

[0041] Specifically, anti-skid pads 4 are provided at the lower ends of the first supporting leg 1 and the second supporting leg 3 to achieve an anti-skid effect during use.

[0042] Specifically, a retractable handle 19 is installed at the upper end of the first supporting leg 1, wherein a retractable tube 17 capable of extending into the interior of the first supporting leg 1 is installed at the lower end of the handle 19, and an in-tube spring buckle 18 is installed inside the retractable tube 17. The positioning pins on the side of the in-tube spring buckle 18 can match with the through holes evenly arranged on the upper part of the first supporting leg 1, thereby satisfying the height adjustment of the handle 19 to expand the range of use by the public.

[0043] Specifically, a locking block 14 is provided at the edge of one of the sub-plates 10, and a locking buckle 12 is provided at the edge of the other sub-plate 10. After the two sub-plates 10 are closed, the locking block 14 and the locking buckle 12 are engaged with each other to lock the two sub-plates 10. When the crutch is used, the locking block 14 and the locking buckle 12 cooperate to prevent the two sub-plates 10 from unfolding, which is safer and more reliable.

[0044] Specifically, the end of the main board 9 has a 90° bent handle 13, a through hole is opened in the middle of the handle 13, and the first support leg 1 passes through the through hole. This arrangement is to make the structure between the main board 9 and the first support leg 1 more stable when in use.

[0045] Preferably, the handle 19 is provided with a flexible webbing 20 which can be adjusted and provided for grasping by hand.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
