Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-2 As shown:

[0026] Example 1:

[0027] A support leg structure with an automatic return mechanism includes a sleeve 101;

[0028] Support legs 102, which are provided in multiple groups and are welded to the surface of the sleeve 101 at equal intervals;

[0029] Automatic return mechanism 2, which is installed inside the sleeve 101;

[0030] Mounting sleeve 103, the mounting sleeve 103 is arranged on the automatic return mechanism 2;

[0031] Elastic support portion 3, the elastic support portion 3 is arranged on the mounting sleeve 103;

[0032] The mounting sleeve 103 rotates to a certain angle relative to the sleeve 101. When the external force potential energy of the mounting sleeve 103 disappears, the mounting sleeve 103 can be driven to automatically return to its original position through the automatic return mechanism 2.

[0033] The automatic return mechanism 2 includes a rotating drum 202 disposed inside the sleeve 101 and a bearing member 201 installed and fixed between the rotating drum 202 and the sleeve 101;

[0034] The bottom of the inner wall of the sleeve 101 is fixed with a base 204, and the upper surface of the base 204 is designed with an inclined surface. A fixed disk 209 is fixed inside the rotating drum 202. The fixed disk 209 slides with a square rod 210 through the sliding hole. The bottom end of the square rod 210 is fixed with a connecting column 205. The outer surface of the square rod 210 is wound with a spring 203. The two ends of the spring 203 are fixedly connected to the fixed disk 209 and the connecting column 205 respectively. The edge surface of the connecting column 205 is fixed. There is a connecting shaft 206, one end of which is rotatably connected to a roller 207 via a bearing. The surface of the roller 207 contacts the inclined surface of the base 204. A sliding groove 208 is provided on the surface of the rotating drum 202 to match the connecting shaft 206. The connecting shaft 206 can slide up and down in the sliding groove 208 provided on the rotating drum 202. A reserved groove is reserved at the top of the base 204 for the rotating drum 202 to rotate, and the mounting sleeve 103 is fixedly mounted on the outer side of the rotating drum 202.

[0035] The elastic support part 3 is composed of a frame plate 301, a mounting hole 302 and a crossbeam 303. The crossbeam 303 is fixed to the surface of the mounting sleeve 103 through a circular hole. The frame plate 301 is fixed on the crossbeam 303. The four corners of the frame plate 301 are provided with mounting holes 302.

[0036] The frame plate 301 is designed to have a concave structure.

[0037] In this embodiment, when using the support leg structure with an automatic return mechanism, first, the seat plate (not shown) is bolted through the mounting hole 1 302 to be mounted on the frame plate 301. Since the frame plate 301 is fixedly connected to the mounting sleeve 103 via the crossbeam plate 1 303,

[0038] Supported by legs 102, which can be four groups of legs 102 and arranged equidistantly. Four groups of legs 102 equidistantly arranged can provide a more stable support base. This symmetrical design helps to evenly distribute the weight of the seat and the user on it, reducing any single point of excessive pressure, thereby reducing the risk of the seat tipping over.

[0039] When a person sits on the seat plate and rotates, the seat plate drives the mounting sleeve 103 to rotate, and the mounting sleeve 103 drives the rotating drum 202 to rotate. By setting the bearing member 201, the stability of the rotating drum 202 during rotation can be achieved, and the rotation effect is smoother. When the rotating drum 202 rotates, it drives the roller 207 to rotate, and the upper surface of the base 204 is designed with an inclined structure, so that when the roller 207 moves on the inclined surface of the base 204, the roller 207 drives the connecting shaft 206 to move upward in the slide groove 208, and the connecting shaft 206 drives the connecting column 205 to move upward, and the connecting column 205 drives the square rod 210 to slide on the fixed plate 209, and at the same time compresses the spring 203. When the person sits on the seat plate and rotates, the seat plate 103 drives the mounting sleeve 103 to rotate, and the mounting sleeve 103 drives the rotating drum 202 to rotate. When leaving, the mounting sleeve 103 on the seat plate drives the rotating drum 202 to disappear when the torsional force, at this time the spring 203 rebounds, and the elastic potential energy stored in the spring 203 is converted into kinetic energy, driving the connecting column 205 to move downward, and the connecting column 205 drives the roller 207 on the connecting shaft 206 to move on the inclined slope of the base 204. When the roller 207 is moved to the bottom of the inclined surface of the base 204, the rotating drum 202 is automatically reset at this time, and then the rotating drum 202 drives the mounting sleeve 103 and the seat plate to reset. Through this operation, after the user gets up and leaves the seat, the automatic return mechanism 2 can automatically drive the elastic support part 3 to drive the seat plate to reset, without manual position adjustment, thereby improving the user's overall experience, and achieving better use effect, meeting actual use needs.

[0040] The design of the frame plate 301 provides good structural strength and can withstand the weight of the user and various forces in daily use. The mounting holes 302 at the four corners are used to fix the seat plate, which can ensure that the seat plate is firmly installed on the frame plate 301. The arc-shaped concave design of the frame plate 301 can provide better support and comfort, because this design can better adapt to the human body curve, thereby reducing fatigue from sitting for a long time. The frame plate 301 is made of elastic steel, so the seat can deform appropriately when under pressure, provide a cushioning effect, reduce the impact on the user's body, and increase comfort.

[0041] Going further;

[0042] In an optional embodiment, the bottom of the support leg 102 is provided with a cross section flush with the ground.

[0043] In this embodiment: the bottom of the support leg 102 is set to have a cross-section flush with the ground, which can increase the contact area between the foot and the ground, thereby improving the overall stability of the seat. Especially on uneven ground or when subjected to lateral force, ensuring that the bottom of the support leg 102 is parallel to the ground helps to maintain the balance of the seat and avoid the seat tilting due to the imbalance of the support leg 102.

[0044] Further,

[0045] like Figure 3 As shown;

[0046] Example 2:

[0047] The elastic support part 3 can also be composed of a bracket 304, a second crossbeam plate 305 and a second mounting hole 306. The bracket 304 has an M-shaped structure and is welded to the surface of the mounting sleeve 103. The surface of the bracket 304 is welded with a second crossbeam plate 305. Two sides of the second crossbeam plate 305 are provided with second mounting holes 306. The bracket 304 is made of elastic steel.

[0048] In this embodiment: the seat plate is bolted through the second mounting hole 306, and the seat plate can be installed on the second crossbeam plate 305, and the M-tubular structure bracket 304 provides good mechanical properties and stability, and can withstand large loads, ensuring that the seat will not be easily deformed or damaged when bearing the weight of the human body and other external forces. The design of the two sets of crossbeam plates 305 can disperse the load and provide additional support points, making the seat as a whole more solid and reducing the deformation of the seat when under force. The bracket 304 is made of elastic steel, so that the seat can be slightly deformed when under pressure, thereby providing buffering, and is suitable for support structures that require elasticity.

[0049] The working principle and use process of the present invention are as follows: when using the support foot structure with an automatic return mechanism, first, the seat plate (not shown in the figure) is passed through the mounting hole 1 302 by bolts and is used to install it on the frame plate 301. Since the frame plate 301 is fixedly connected by the crossbeam plate 1 303 and the mounting sleeve 103; it is supported by the support legs 102. The support legs 102 can be four groups and are arranged equidistantly. The four groups of equidistantly arranged support legs 102 can provide a more stable support base. This symmetrical design helps to evenly distribute the weight of the seat and the user on it, reducing any single point of excessive pressure, thereby reducing the risk of the seat tipping over; when a person sits on the seat plate and rotates, the seat plate drives the mounting sleeve 103 to rotate, and the mounting sleeve 103 drives the rotating drum 202 to rotate. The arrangement of the bearing member 201 can achieve stability during the rotation of the rotating drum 202, and the rotation effect is smoother. When the rotating drum 202 rotates, it drives the roller 207 to rotate, and the upper surface of the base 204 is designed with an inclined structure, so that the roller When the wheel 207 moves on the inclined surface of the base 204, the roller 207 drives the connecting shaft 206 to move upward in the slide groove 208. At the same time, the connecting shaft 206 drives the connecting column 205 to move upward, and the connecting column 205 drives the square rod 210 to slide on the fixed plate 209, and at the same time compresses the spring 203. When the person leaves, the mounting sleeve 103 on the seat plate drives the rotating drum 202 to disappear. At this time, the spring 203 rebounds, and the elastic potential energy stored in the spring 203 is converted into kinetic energy, driving the connecting column 205 to move downward, and the connecting column 205 is compressed. The column 205 drives the roller 207 on the connecting shaft 206 to move on the inclined slope of the base 204. When the roller 207 is moved to the bottom of the inclined surface of the base 204, the rotating drum 202 is automatically reset, and then the rotating drum 202 drives the mounting sleeve 103 and the seat plate to reset. Through this operation, after the user gets up and leaves the seat, the automatic return mechanism 2 can automatically drive the elastic support part 3 to drive the seat plate to reset, without the need for manual position adjustment, thereby improving the user's overall experience, achieving better use effects, and meeting actual use needs.
