The limiting piece 3 moves along the direction perpendicular to the extension direction of the first connecting rod 121, so that the limiting piece 3 moves to the bottom of the first connecting rod 121 and the second connecting rod 122, and the first connecting rod 121 and the second connecting rod 122 are limited in position by the limiting piece 3 during the rotation of the end portion to the bottom. The movement of the limiting piece 3 along the direction perpendicular to the extension direction of the first connecting rod 121 achieves avoidance, and only the thickness of the mounting seat in the direction perpendicular to the extension direction of the first connecting rod 121 needs to be ensured, so that the occupied length and width space is small and does not affect the close-up between the two standing columns 11 after folding.

[0042] It should be noted that the mounting seat 2 is arranged at the connection of the first connecting rod 121 and the second connecting rod 122, and the mounting seat 2 can be arranged in various ways, for example, it can be mounted on one of the first connecting rod 121 or the second connecting rod 122, or it can be directly mounted at the connection of the first connecting rod 121 and the second connecting rod 122.

[0043] Among them, one end of the first connecting rod 121 and the second connecting rod 122 can rotate relatively, and the end portion of the first connecting rod 121 and the second connecting rod 122 can be directly connected or connected through other pieces.

[0044] Further, in the embodiment, the first connecting rod 121 is rotatably installed on the mounting base 2 through a first rotating shaft 13, and the second connecting rod 122 is rotatably installed on the mounting base 2 through a second rotating shaft 14; part of the first connecting rod 121 extends to the other side of the first rotating shaft 13 to form a first extension 121a, and part of the second connecting rod 122 extends to the other side of the second rotating shaft 14 to form a second extension 122a, the first extension 121a and the second extension 122a are arranged side by side in a direction perpendicular to the extension direction of the first connecting rod 121; in the limiting position, the limiting piece 3 at least simultaneously abuts against the first extension 121a and the second extension 122a. In the embodiment, the first connecting rod 121 and the second connecting rod 122 are both rotatably installed on the mounting base 2, which facilitates the fixation between the mounting base 2 and the first connecting rod 121 and the second connecting rod 122, avoids the mounting base 2 from falling off, and at the same time, facilitates the relative rotation of the first connecting rod 121 and the second connecting rod 122, and through the abutment between the first extension 121a, the second extension 122a and the limiting piece 3, the synchronous limiting and unlocking of the first connecting rod 121 and the second connecting rod 122 is facilitated, which is simple to operate and facilitates the stable operation of the frame.

[0045] Further, the first connecting rod 121 is provided with a first avoiding space matched with the second extension 122a, and the second connecting rod 122 is provided with a second avoiding space matched with the first extension 121a; the first connecting rod 121 and the second connecting rod 122 are mutually staggered in the extension direction of the first connecting rod 121.

[0046] It should be noted that, in order to make the limiting piece 3 move between the limiting position and the avoiding position, the limiting piece 3 has various movement modes, for example, the limiting piece 3 is linearly movably arranged on the mounting base 2 and reciprocally moves between the limiting position and the avoiding position, thereby limiting or avoiding the first connecting rod 121 and the second connecting rod 122.

[0047] In another aspect, the limiting piece 3 is rotationally mounted on the mounting seat 2, wherein the rotation axis of the limiting piece 3 is arranged along a direction perpendicular to the extending direction of the first connecting rod. The limiting piece 3 can rotate in multiple directions as long as it is rotationally mounted on the mounting seat 2.

[0048] In the embodiment, the limiting piece 3 is rotationally mounted on the mounting seat, and the rotation axis of the limiting piece 3 is arranged along a direction parallel to the extending direction of the first connecting rod. The transmission mechanism includes a first transmission rod 42 movably arranged on the stand 11. The first transmission rod 42 is movably arranged on the mounting seat 2, and the end of the first transmission rod 42 away from the stand 11 is opposite to the position of the limiting piece 3 to push the limiting piece 3 to rotate in a first direction when the first transmission rod 42 approaches the limiting piece 3, so as to rotate to the avoiding position. The end of the first transmission rod 42 toward the limiting piece 3 is provided with a slant guide surface 411, which is arranged to be inclined in the first direction as a whole. Alternatively, the limiting piece 3 is provided with a slant guide surface 411, which is arranged to be inclined in a direction away from the first direction as a whole. In the embodiment, the limiting piece 3 is rotationally mounted on the mounting seat, so that the limiting piece 3 occupies less space in the up-down direction or thickness direction, facilitating the miniaturization of the limiting piece 3.

[0049] The first transmission rod 42 is movably arranged to abut against the side wall surface of the limiting piece 3. By arranging the slant guide surface 411, the first transmission rod 42 can drive the limiting piece 3 to rotate during the linear movement of the first transmission rod 42, facilitating the movement of the first transmission rod 42 to one side of the limiting piece 3, avoiding the top dead center between the first transmission rod 42 and the limiting piece 3, and realizing that the first transmission rod 42 can gradually drive the limiting piece 3 to rotate.

[0050] It should be noted that the slant guide surface 411 can be arranged on the first transmission rod 42, or on the limiting piece 3, or on both the driving part 41 and the limiting piece 3, so as to facilitate the cooperation between the first transmission rod 42 and the limiting piece 3.

[0051] Specifically, in order to facilitate the cooperation between the first transmission rod 42 and the limiting piece 3, the limiting piece 3 is formed with a cooperation groove 412, and the end of the first transmission rod 42 is arranged in the cooperation groove 412.

For example, a mounting hole is formed on the limiting piece 3, a rotating hole is formed on the mounting seat 2, a rotating shaft is arranged in the rotating hole, and the rotating shaft is installed in the mounting hole, so that the limiting piece 3 is rotatably installed on the mounting seat 2. The specific installation mode is not limited herein.

[0054] In addition, referring to Figures 5-6 , the first transmission rod 42 is parallel to the first connecting rod 121 and is rotatably installed on the stand column 11. The first transmission rod 42 is slidingly arranged on the mounting seat 2 along the extension direction of the first connecting rod 121, and when the stand column 11 swings inward, the first transmission rod 42 is driven to slide on the mounting seat 2 towards the limiting piece 3. In this embodiment, the first transmission rod 42 is arranged parallel to the extension direction of the first connecting rod, so that the first transmission rod 42 and the first connecting rod 121 are arranged in the length direction on the stand column 11. When the stand column 11 tilts, the first transmission rod 42 is driven to relatively displace with respect to the first connecting rod 121, and when the stand column 11 swings inward, the first transmission rod 42 is driven to slide on the mounting seat 2 towards the limiting piece 3, facilitating the transmission between the stand column 11 and the limiting piece 3.

[0055] It should be noted that in this embodiment, the first transmission rod 42 is installed on the mounting seat 2 through a mounting shaft. A waist hole 23 is formed on the mounting seat, and the mounting shaft is slidingly and rotatably installed in the waist hole 23, so that the first transmission rod 42 is slidingly and rotatably installed in the mounting seat 2.

[0056] Specifically, in this embodiment, the transmission mechanism further comprises a second transmission rod 43. The second transmission rod 43 is arranged on the two sides of the mounting seat 2 opposite to the first transmission rod 42. The second transmission rod 43 and the first transmission rod 42 are respectively arranged on two adjacent stand columns 11. When the two stand columns 11 swing inward, the first transmission rod 42 and the second transmission rod 43 simultaneously cooperate with the limiting piece 3 to drive the limiting piece 3 to move to the avoiding position. In this embodiment, the same limiting piece 3 is simultaneously driven from two sides by two groups of transmission rods (the second transmission rod 43 and the first transmission rod 42), so as to facilitate the stable driving of the limiting piece 3, and avoid that the limiting piece 3 cannot be driven to displace when one of the transmission rods fails.

[0057] In another aspect, the folding frame 100 further comprises a reset member 5, which is arranged between the limiting member 3 and the mounting base 2, and generates an elastic force to drive the limiting member 3 to rotate to the limiting position when the limiting member 3 is in the avoiding position. In the embodiment, the reset member can realize the automatic reset of the limiting member 3, and facilitate the automatic limiting after the frame is unfolded.

[0058] It should be noted that the reset member can have various embodiments, such as a spring. In the embodiment, the reset member 5 is a torsion spring, which is sleeved on the rotating shaft of the limiting member 3.

[0059] In another aspect, in the embodiment, the mounting base 2 comprises a fixed plate 21 and a fixed seat 22. Two fixed plates 21 are arranged in a spaced manner. The fixed seat 22 is arranged between the two fixed plates 21, and cooperates with the two fixed plates 21 to define a containing cavity. The connecting part of the first connecting rod 121 and the second connecting rod 122 is arranged in the containing cavity, so as to facilitate the installation of the first connecting rod 121 and the second connecting rod 122.
