[0008] In one embodiment, when in the limiting position, the limiting member is located at the bottom of the first connecting rod and the second connecting rod and abuts against the first connecting rod and the second connecting rod at the same time;

[0009] The transmission mechanism drives the limiting member to move along an extending direction perpendicular to the first connecting rod to leave the limiting position.

[0010] In one embodiment, the first connecting rod is rotatably mounted on the mounting seat via a first rotating shaft, and the second connecting rod is rotatably mounted on the mounting seat via a second rotating shaft; a portion of the first connecting rod extends to the other side of the first rotating shaft to form a first extension portion, and a portion of the second connecting rod extends to the other side of the second rotating shaft to form a second extension portion, and the first extension portion and the second extension portion are arranged side by side in a direction perpendicular to the extension direction of the first connecting rod;

[0011] When in the limiting position, the limiting member abuts against at least the first extending portion and the second extending portion simultaneously.

[0012] In one embodiment, a first avoidance space adapted to the second extension portion is provided on the first connecting rod, and a second avoidance space adapted to the first extension portion is provided on the second connecting rod; the first connecting rod and the second connecting rod are offset from each other in the extension direction of the first connecting rod.

[0013] In one embodiment, the limiting member is rotatably mounted on the mounting seat, and the rotation axis of the limiting member is arranged parallel to the extension direction of the first connecting rod;

[0014] The transmission mechanism comprises a first transmission rod movable on the column, the first transmission rod being movably arranged on the mounting seat, and one end of the first transmission rod away from the column is opposite to the position of the limiter so as to push the limiter to rotate in a first direction to the avoidance position when the transmission rod approaches the limiter;

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement.

[0036] At present, as indoor products for babies, children's beds can be unfolded and folded for use, but the folding method of general children's beds is relatively complicated, requiring the separate unlocking and active folding of various parts, resulting in complex overall operation, which is not conducive to the user's quick storage. In summary, the folding operation method of existing children's beds is relatively complicated.

[0037] See also Figure 1 to Figure 2 The present invention provides a folding frame 100, comprising a frame, a mounting seat 2, a stopper 3 and a transmission mechanism; the frame comprises a plurality of columns 11 and an upper enclosure rod assembly supported between adjacent columns 11; the upper enclosure rod assembly comprises a first link 121 and a second link 122 that can be rotatably folded, and a mounting seat 2 disposed between the first link 121 and the second link 122, the first link 121 and the second link 122 can respectively rotate toward the corresponding column 11 and bring the two columns 11 closer to each other to fold the frame; the stopper 3 The member 3 is movably arranged on the mounting seat 2, and has a limit position and an avoidance position in its movable range. When in the limit position, the limit member 3 limits the first link 121 and the second link 122 from rotating in the folding direction, and when in the avoidance position, the limit member 3 avoids the folding path of the first link 121 and the second link 122; the transmission mechanism is transmission-connected between the limit member 3 and the column 11, so as to drive the limit member 3 to move from the limit position to the avoidance position when the bottom of the column 11 swings inward.

[0038] The folding frame is folded by rotating the first link 121 and the second link 122, so that the two columns 11 can approach and move away from each other. When the frame is in the supporting state, the first link 121 and the second link 122 are limited in rotation by the mounting seat 2 and the limiting member 3, so that the multiple columns 11 cannot approach each other, ensuring that the frame can be in the supporting state. During the folding process of the folding frame 100, the bottom of the column 11 is swung inward, and the swing is transmitted to the limiting member 3 through the transmission mechanism, and the limiting member 3 is driven to move toward the avoidance position, so that the first link 121 and the second link 122 can rotate with each other, thereby allowing the two columns 11 to approach each other. During the folding process, it is only necessary to drive the column 11 to move, so that the restriction of the limiting member 3 on the first link 121 and the second link 122 can be released, and there is no need to unlock multiple components separately, thereby simplifying the folding process and facilitating the rapid folding of the folding frame 100.

[0039] It should be noted that the limiting member 3 is movably provided on the mounting seat 2 to limit or avoid the rotation of the first connecting rod 121 and the second connecting rod 122. When in the limiting position, the limiting member 3 can limit the first connecting rod 121 and the second connecting rod 122 in a variety of ways. The limiting member 3 can be sleeved on the first connecting rod 121 and the second connecting rod 122 to limit the rotation, or can be simultaneously passed through the first connecting rod 121 and the second connecting rod 122 to achieve the limitation of the rotation.

[0040] When the frame is in the supporting state, the plurality of columns 11 are away from each other, and the first connecting rod 121 and the second connecting rod 122 between two adjacent columns 11 are also in an extended and unfolded state. When the frame is driven to be converted to the folded state, the plurality of columns 11 are close to each other, and the first connecting rod and the second connecting rod are rotated to be folded together, so that the entire frame is finally contracted and folded as a whole.

[0041] Further, in this embodiment, please refer to Figure 3 to Figure 4, when in the limit position, the limit member 3 is located at the bottom of the first link 121 and the second link 122 and is in contact with the first link 121 and the second link 122 at the same time; the transmission mechanism drives the limit member to move along the extension direction perpendicular to the first link 121 to leave the limit position. The limit member 3 moves along the extension direction perpendicular to the first link 121, so that the limit member 3 moves to the bottom of the first link 121 and the second link 122. The first link 121 and the second link 122 are limited by the limit member 3 in the process of rotating so that the ends move toward the bottom. The limit member 3 moves along the extension direction perpendicular to the first link 121 to achieve avoidance. It is only necessary to ensure the thickness of the mounting seat in the extension direction perpendicular to the first link 121. The length and width space occupied is small, and it will not affect the closeness between the two columns 11 after folding.

[0042] It should be noted that the mounting seat 2 is arranged at the connection between the first connecting rod 121 and the second connecting rod 122. There are various ways to set the mounting seat 2. It can be installed on one of the first connecting rod 121 or the second connecting rod 122, or it can be directly mounted at the connection between the first connecting rod 121 and the second connecting rod 122.

[0043] One end of the first connecting rod 121 and one end of the second connecting rod 122 can generate relative rotation, and the ends of the first connecting rod 121 and the second connecting rod 122 can be directly rotatably connected or installed through other parts.

[0044] Furthermore, in the present embodiment, the first connecting rod 121 is rotatably mounted on the mounting base 2 via the first rotating shaft 13, and the second connecting rod 122 is rotatably mounted on the mounting base 2 via the 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 portion 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 portion 122a, and the first extension portion 121a and the second extension portion 122a are arranged side by side in a direction perpendicular to the extension direction of the first connecting rod 121; when in the limiting position, the limiting member 3 is in contact with at least the first extension portion 121a and the second extension portion 122a at the same time. In this embodiment, the first connecting rod 121 and the second connecting rod 122 are both rotatably mounted 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, and prevents the mounting base 2 from falling off. At the same time, it facilitates the relative rotation of the first connecting rod 121 and the second connecting rod 122, and the first extension portion 121a and the second extension portion 122a are abutted against the limiting member 3 to facilitate the synchronous limiting and synchronous unlocking of the first connecting rod 121 and the second connecting rod 122, which is simple to operate and facilitates the stable operation of the frame.

[0045] Furthermore, the first connecting rod 121 is provided with a first avoidance space adapted to the second extension portion 122a, and the second connecting rod 122 is provided with a second avoidance space adapted to the first extension portion 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. In this embodiment, the second extension portion 122a is provided corresponding to the first avoidance space, and the first extension portion 121a is provided corresponding to the second avoidance space, so that the ends of the first connecting rod 121 and the second connecting rod 122 are staggered, so that the ends of the first connecting rod 121 and the second connecting rod 122 can be more closely fitted, so that the length space occupied by the first connecting rod 121 and the second connecting rod 122 is shorter.

[0046] It should be noted that, in order to enable the limit member 3 to move between the limit position and the avoidance position, the limit member 3 has a variety of movement modes. For example, the limit member 3 is arranged on the mounting seat 2 and moves along a straight line, and reciprocates between the limit position and the avoidance position to achieve the limitation or avoidance of the first connecting rod 121 and the second connecting rod 122.

[0047] On the other hand, the limit member 3 is rotatably mounted on the mounting seat 2, wherein the rotation axis of the limit member 3 can be along a direction perpendicular to the extension direction of the first connecting rod. The limit member 3 only needs to be rotatably mounted on the mounting seat 2, and its rotation direction can be multiple.

[0048] In this embodiment, the stopper 3 is rotatably mounted on the mounting seat, the rotation axis of the stopper 3 is arranged along a direction parallel to the extension direction of the first connecting rod, the transmission mechanism includes a first transmission rod 42 movable on the column 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 column 11 is opposite to the stopper 3 so that when the first transmission rod 42 approaches the stopper 3, the stopper 3 is pushed to rotate in the first direction to the avoidance position; the first transmission rod 42 is provided with an oblique guide surface 411 at one end facing the stopper 3, and the oblique guide surface 411 is arranged obliquely in the first direction as a whole; or the stopper 3 is provided with an oblique guide surface 411, and the oblique guide surface 411 is arranged obliquely in a direction away from the first direction as a whole. In this embodiment, the stopper 3 is rotatably mounted on the mounting seat, so that the vertical space or thickness space occupied by the stopper 3 is smaller, which is convenient for miniaturization of the stopper 3.

[0049] Among them, the first transmission rod 42 moves to make it abut against the side wall surface of the limit member 3. By setting the inclined guide surface 411, the first transmission rod 42 can drive the limit member 3 to rotate during the linear movement, so that the first transmission rod 42 can move to one side of the limit member 3 to avoid the two from getting stuck, so that the first transmission rod 42 can gradually drive the limit member 3 to rotate.

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

[0051] Specifically, in order to facilitate the cooperation between the first transmission rod 42 and the limiting member 3, a cooperation groove 412 is formed on the limiting member 3, the end of the first transmission rod 42 is placed in the cooperation groove 412, and the inclined guide surface 411 is arranged between the cooperation groove and the first transmission rod 42 to save space.

[0052] The limiting member 3 includes a mounting section and a limiting section. The mounting section is rotatably mounted on the mounting seat 2 . The limiting section rotates between the limiting position and the avoidance position. The first transmission rod 42 abuts against the mounting section.

[0053] The limiting member 3 is rotatably mounted on the mounting seat 2, wherein there are multiple ways to rotatably mount the limiting member 3, for example, a mounting hole is formed on the limiting member 3, a rotating hole is formed on the mounting seat 2, a rotating shaft is passed through the rotating hole, and is mounted in the mounting hole, so that the limiting member 3 is rotatably mounted on the mounting seat 2, and no specific restrictions are made here.

[0054] Also, see Figures 5 and 6 , the first transmission rod 42 is arranged parallel to the first connecting rod 121 and is rotatably mounted on the column 11, the first transmission rod 42 is slidably arranged on the mounting seat 2 along the extension direction of the first connecting rod 121, and drives the first transmission rod 42 to slide along the mounting seat 2 toward the direction close to the stopper 3 when the column 11 swings inward. In this embodiment, the first transmission rod 42 is arranged along the extension direction parallel to the first connecting rod, so that the first transmission rod 42 and the first connecting rod 121 are arranged along the length direction on the column 11. At this time, when the column 11 tilts, it drives the first transmission rod 42 to produce relative displacement relative to the first connecting rod 121, and drives the first transmission rod 42 to slide along the mounting seat 2 toward the direction close to the stopper 3 when the column 11 swings inward, so as to facilitate the transmission between the column 11 and the stopper 3.

[0055] It should be noted that, in the present embodiment, the first transmission rod 42 is installed on the mounting seat 2 via a mounting shaft, wherein a waist hole 23 is formed on the mounting seat, and the mounting shaft is slidably and rotatably installed in the waist hole 23, so that the first transmission rod 42 slides and is rotatably installed in the mounting seat 2.

[0056] Specifically, in this embodiment, the transmission mechanism further includes a second transmission rod 43, which is arranged on both sides of the mounting seat 2 opposite to the first transmission rod 42, and the second transmission rod 43 and the first transmission rod 42 are respectively movable on two adjacent vertical rods 11, and when the two vertical rods 11 swing inward, the first transmission rod 42 and the second transmission rod 43 cooperate with the limiter 3 at the same time to drive the limiter 3 to move toward the avoidance position. In this embodiment, the same limiter 3 is driven from both sides at the same time by two sets of transmission rods (the second transmission rod 43 and the first transmission rod 42), which facilitates the stable driving of the limiter 3 and avoids the inability to drive the limiter 3 to produce displacement when one of the transmission rods fails.

[0057] On the other hand, the folding frame 100 further includes a reset member 5, which is disposed between the limit member 3 and the mounting seat 2. When the limit member 3 is in the avoidance position, the reset member 5 generates an elastic force that drives the limit member 3 to rotate toward the limit position. In this embodiment, the limit member 3 can be automatically reset by the reset member, which facilitates the automatic limit of the frame after unfolding.

[0058] It should be noted that the reset member may have various implementations, such as a spring. In the present embodiment, the reset member 5 is a torsion spring, and the torsion spring is sleeved on the rotation axis of the limiting member 3 .

[0059] On the other hand, in this embodiment, the mounting seat 2 includes a fixing plate 21 and a fixing seat 22; two fixing plates 21 are provided, and the two fixing plates 21 are arranged at intervals; the fixing seat 22 is arranged between the two fixing plates 21, and together with the two fixing plates 21, a containing cavity is defined, and the connection between 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.

[0060] Based on the above-mentioned folding frame 100, the present invention further provides a children's tool, including all the technical features of the above-mentioned folding frame, and therefore, also has the technical effects brought by all the above-mentioned technical features, which will not be described one by one here.

[0061] Wherein, the children's appliance is a children's bed for children to lie down.

[0062] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
