[0025] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0026] An embodiment of the present application provides a collapsible support leg, as Figure 1 , Figure 2 shown, mainly including a support leg 1, a first support rod 2, a second support rod 3, a third support rod 4, a fourth support rod 5 and a lock 6. In practical applications, two sets of collapsible support legs can be symmetrically installed. In the subsequent examples of the embodiments of the present application, one set is taken as an example for illustration. Specifically, the collapsible support leg of the embodiment of the present application includes:

[0027] The support leg 1 is connected to the target device through a first pin shaft 7. The support leg 1 can rotate around the first pin shaft 7 and has a deformed "U" - shaped structure. A first support rod 2 is provided on the side opposite to its connection with the target device, and the first support rod 2 can rotate.

[0028] The first support rod 2 has a deformed "U" - shaped structure. The other side of its rotating shaft is connected to the second support rod 3 through a second pin shaft 9, and the other side of its rotating shaft is connected to the second support rod 3 and the third support rod 4 through a third pin shaft 10. The second pin shaft 9 and the third pin shaft 10 are coaxial. The third support rod 4 has a "one" - shaped straight rod structure, and one end of it is connected to the first support rod 2 and the second support rod 3 through the third pin shaft 10, so that the third support rod 4, the first support rod 2 and the second support rod 3 can rotate relative to each other.

[0029] As Figure 3As shown, in some examples, the support leg 1 is a deformed "U" - shaped structure. The top of the support leg 1 is fixed to the pin seat 8 at the bottom of the target device by two first pins 7, and the support leg 1 can rotate freely around the first pin 7. The bottom of the support leg 1 is connected to the first support rod 2 by a pin, and the support leg 1 and the first support rod 2 can rotate freely between each other.

[0030] As Figure 4 shown, the first support rod 2 is a deformed "U" - shaped structure. One side of the top of the first support rod 2 is connected to the second support rod 3 by a second pin 9, and at the same time, the other side of the top of the first support rod 2 is connected to the second support rod 3 and the third support rod 4 by a third pin 10. The second pin 9 and the third pin 10 are coaxial, so the three support rods can rotate freely with each other. The bottom of the first support rod 2 is connected to the support leg 1, and the first support rod 2 and the support leg 1 can rotate freely between each other.

[0031] As Figure 5 shown, the second support rod 3 is a deformed "U" - shaped structure. The top of the second support rod 3 is connected to the pin seat installed on the bottom surface of the target device by a fourth pin 11, and the second support rod 3 can rotate freely around the fourth pin 11. One side of the bottom of the second support rod 3 is connected to the first support rod 2 by a second pin 9, and at the same time, the other side of the bottom of the second support rod 3 is connected to the first support rod 2 and the third support rod 4 by a third pin 10. The second pin 9 and the third pin 10 are coaxial, so the three support rods can rotate freely with each other.

[0032] As Figure 6 shown, the third support rod 4 is a "one" - shaped straight rod structure. The top of the third support rod 4 is connected to the first support rod 2 and the second support rod 3 by a third pin 10, and the three support rods can rotate freely with each other. The middle position of the third support rod 4 is connected to the fourth support rod 5 by a fifth pin 12, and the third support rod 4 and the fourth support rod 5 can rotate freely between each other.

[0033] The fourth support rod 5 is a deformed "L" - shaped straight rod structure. One end of it is connected to the target device by a fourth pin 13. The fourth support rod 5 is connected to the third support rod 4 by a fifth pin 12. The third support rod 4 and the fourth support rod 5 are rotatable. A lock 6 is arranged on the fourth support rod 5, and the lock 6 can slide along the fourth support rod 5.

[0034] As Figure 7 shown, the top of the fourth support rod 5 is connected to the pin seat on the bottom surface of the target device by a fourth pin 13, and the fourth support rod 5 can rotate freely around the pin 13. The bottom of the support rod 5 is connected to the support rod 4 by a fifth pin 12, and the third support rod 4 and the fourth support rod 5 can rotate freely between each other. A lock 6 is installed on the fourth support rod 5, and the lock 6 can slide along the fourth support rod 5.

[0035] The embodiment of the present application proposes a support leg that is attached to the surface of a target device, occupies a small volume when folded, and can stably support the target device when unfolded.

[0036] In some embodiments, as Figure 8 As shown, the lock 6 is a rectangular sleeve-shaped structure. In some embodiments, the lock 6 is sleeved on the fourth support rod 5 and moves with the fourth support rod 5, and can slide along the fourth support rod 5. When the fourth support rod 5 and the third support rod 4 rotate to a straight line, the lock 6 slides along the fourth support rod 5 to a locked position to lock the relative rotation of the fourth support rod 5 and the third support rod 4. The fourth support rod 5 and the third support rod 4 are locked.

[0037] In some embodiments, as Figure 3 As shown, the rotatable edge of the first support rod 2 is connected to the edge of the support leg 1 on the side opposite to the target device, and the connected edge is conformal to the edge of the support leg 1 on the side opposite to the target device.

[0038] The foldable support leg of the embodiment of the present application can be completely folded and stored within the bottom plane of the target device before use. When in use, the support leg 1 is pulled downward. When the support leg 1 rotates about its axis, it drives the first support rod 2 and the second support rod 3 to move together. When the first support rod 2 and the second support rod 3 move, the third pin 10 drives the third support rod 4 and the fourth support rod 5 to move. As the support leg 1 moves downward to a vertical position, the first support rod 2 and the second support rod 3 gradually move into the same plane, at which point the third support rod 4 and the fourth support rod 5 also move into a straight line. When the support leg 1 moves to the vertical position, the first support rod 2 and the second support rod 3 are in the same plane, and the third support rod 4 and the fourth support rod 5 are in the same straight line. At this time, the lock 6 is slid from the fourth support rod 5 along the straight line formed by the third support rod 4 and the fourth support rod 5, so that the lock 6 covers the positions of the third support rod 4 and the fourth support rod 5 at the same time. At this point, the relative rotation between the third support rod 4 and the fourth support rod 5 is locked, forming a stable structure. The third support rod 4, the fourth support rod 5 and the lock 6 form a stable structure, the bottom surface of the device and the second support rod 3 to form a triangular support structure with stable shape, and the movement of the second support rod 3 is locked. At this time, the structure formed by the first support rod 2 and the second support rod 3 is locked at the same time, forming a stable plane. At this time, the structure formed by the first support rod 2 and the second support rod 3, the bottom surface of the device, and the support leg 1 form another triangular support structure, such as Figure 9 As shown, the movement of the support leg 1 is locked, thereby forming a stable support leg structure.

[0039] The embodiment of the present application utilizes a five-link mechanism to achieve a foldable support leg. When folded, it occupies only a limited amount of space at the bottom of the device. Furthermore, by using five links, the locking force required to lock the link structure is reduced, the strength of the locking mechanism can be easily met, and the mechanism is more rigid.

[0040] The embodiment of the present application further provides a platform device, to which two foldable support legs as described above are connected.
