As shown in fig. 1 to 3, an embodiment of the present application provides a folding structure, including: the foldable device comprises a base 1 and two folding assemblies 2, wherein the number of the base 1 is two, and the folding assemblies 2 are arranged in two groups and are respectively arranged on the two bases 1;

each group of folding assemblies 2 comprises four folding arms 21, the four folding arms 21 are uniformly distributed along the circumferential direction of the base 1, and each folding arm 21 comprises two parallel support arms, a top rod 22, a locking structure and a connecting seat 3;

the first ends of the two support arms are hinged with the base 1, the second ends of the two support arms are hinged with the connecting seat 3, the first end of the ejector rod 22 is hinged with one support arm, the other support arm is provided with a sliding groove 27, the second end of the ejector rod 22 is provided with an ejector rod pin shaft 29, and the ejector rod pin shaft 29 is slidably arranged in the sliding groove 27;

the locking structure is used for limiting the rotation of the mandril 22 when the two support arms are unfolded relative to the base 1;

two connecting seats 3 adjacent to one side in the folding assembly 2 of the first group are fixedly connected with two connecting seats 3 adjacent to one side in the folding assembly 2 of the second group.

In the present embodiment, the folding structure mainly comprises two parts, namely a base 1 and two folding assemblies 2, wherein the base 1 is used as a mounting base of the folding assemblies 2 and is provided in two, each base 1 is provided with a group of folding assemblies 2, and each group of folding assemblies 2 comprises at least two folding arms 21.

The folding arm 21 consists of two support arms, a top rod 22, a locking structure and a connecting seat. In this embodiment, the two arms are an upper arm 24 and a lower arm 25, the upper arm 24 and the lower arm 23 are parallel, and the first ends of the upper arm 24 and the top bar 22 are hinged to the base 1 through a first pin, so that the upper arm 24 can rotate clockwise or counterclockwise. The lower arm 23 is hinged to the base 1 below the upper arm 24 by a second pin so that the lower arm 23 can also rotate clockwise or counterclockwise. In order to enable the upper arm 24 and the lower arm 23 to rotate synchronously and to support after rotating and unfolding, in this embodiment, a sliding slot 27 is formed in the lower arm 23, the opening direction of the sliding slot 27 is the length direction of the lower arm 23, a top rod pin 29 is fixedly arranged at the second end of the top rod 22, and the top rod pin 29 is inserted into the sliding slot 27 and is connected with the sliding slot 27 in a sliding manner. The first end of the sliding slot 27 is close to the hinge point of the lower arm 23 and the base 1, and the second end is far away from the hinge point of the lower arm 23 and the base 1.

When the base 1 is in the folded state, taking the base 1 in the horizontal state as an example, as shown in fig. 3, the upper support arm 24 and the lower support arm 23 rotate counterclockwise to the vertical state, and at the same time, the base 1 rises vertically, and at this time, the push rod pin 29 slides to the first end of the sliding groove 27; when the foldable table is in the unfolded state, the upper support arm 24 and the lower support arm 23 rotate clockwise to the horizontal state, and simultaneously the base 1 descends vertically, at this time, the ejector pin shaft 29 slides to the second end of the sliding groove 27, and is limited by the second end of the sliding groove 27, so that the ejector pin shaft 29 cannot move further, and the upper support arm 24 and the lower support arm 23 cannot rotate clockwise further. Because the embodiment has two bases 1, and the two bases 1 form an integrated structure through the corresponding folding arms 21 and the connecting seat 3, the two bases 1 can be synchronously lifted or lowered in the unfolding and folding processes.

Similarly, as shown in fig. 4, a sliding slot 27 may be formed on the upper arm 24, and when this mode is selected, a first end of the top rod 22 needs to be hinged to the lower arm 23, and a top rod pin 29 is disposed at a second end thereof, so that the top rod pin 229 is slidably disposed in the sliding slot 27 of the upper arm.

In order to stabilize the folding structure in this embodiment when the folding structure is pressed upward or downward after being unfolded, a locking structure is additionally provided in this embodiment, and the locking structure functions to limit the rotation of the push rod 22 in the counterclockwise direction when the upper arm 24 and the lower arm 23 are in the unfolded state. When the top bar 22 cannot rotate counterclockwise, the upper arm 24 and the lower arm 23 connected thereto cannot rotate counterclockwise. The form of the locking structure can be varied, for example, by holding the push rod pin 29 in the slide slot 27, or by passing a latch through the upper arm 24 and the push rod 22, or by passing a latch through the lower arm 23 and the push rod 22.

Since the upper arm 24 and the lower arm 23 as the folding structure in this embodiment are rotated from the horizontal state to the vertical state when folded, when the upper arm 24 and the lower arm 23 are mounted on the base 1 in a plurality of directions, the upper arm 24 and the lower arm 23 in each direction can be rotated from the horizontal state to the vertical state, and therefore the lateral occupied space after folding and storage can be greatly reduced. Meanwhile, the upper support arm 24 and the lower support arm 23 can be locked after being unfolded through the locking structure in the embodiment, and the use stability is improved.

As shown in fig. 2, taking the sliding groove 27 opened on the lower arm 23 as an example, the locking structure includes a pull rod 28 and an elastic member 25; the pull rod 28 is hinged with the lower support arm 23 through a third pin shaft, the elastic piece 25 is arranged on the lower support arm 23 and is connected with the pull rod 28,

when the upper arm 24 and the lower arm 23 are unfolded relative to the base 1, the pull rod 28 rotates to be pressed against the push rod pin 29 under the elastic force of the elastic piece 25, so as to limit the displacement of the push rod pin 29 in the sliding groove 27;

when the upper arm 24 and the lower arm 23 are folded with respect to the base 1, the pull rod 28 rotates parallel to the slide slot 27 and compresses the elastic member 25.

Specifically, it should be noted that the pull rod 28 is hinged in the lower arm 23 through a pin, and an axis of the pin connecting the pull rod 28 and the lower arm 23 is parallel to an axis of the pin connecting the lower arm 23 and the base 1. When the unlocking is needed, the pull rod 28 is pulled and the elastic piece 25 is compressed, at the moment, one end of the pull rod 28 corresponding to the ejector pin shaft 29 rotates anticlockwise to be staggered with the ejector pin shaft 29, so that the ejector pin shaft 29 can slide in the sliding groove 27 to realize the folding and containing functions. And the push rod pin 29 will contact with the side surface of the pull rod 28 when the storage box is stored, and the pull rod 28 is always in a state of compressing the elastic piece 25.

When the upper arm 24 and the lower arm 23 are in the unfolded state, the top rod 22 rotates along with the top rod and the top rod pin 29 slides to the second end of the sliding groove 27, and further rotation of the top rod 22 and further rotation of the upper arm 24 and the lower arm 23 are limited due to the sliding groove 27. And the ejector pin shaft 29 sliding to the second end of the sliding groove 27 is staggered with the pull rod 28 at this time, and will not be abutted against the side surface of the pull rod 28 any more, the end of the pull rod 28 corresponding to the ejector pin shaft 29 is tilted under the action of the elastic part 25 and is flush with the ejector pin shaft 29, at this time, the ejector pin shaft 29 is abutted against the end surface of the pull rod 28, at this time, the ejector pin shaft 29 cannot freely move in the sliding groove 27, the ejector 22 cannot rotate, and further, the upper support arm 24 and the lower support arm 23 cannot rotate, so that the upper support arm 24 and the lower support arm 23 cannot be accommodated and shaken, and the stability is improved.

Similarly, as shown in fig. 4, taking the sliding slot 27 opened on the upper arm 24 as an example, the locking structure includes a pull rod 28 and an elastic member 25; the pull rod 28 is hinged with the upper support arm 24 through a third pin shaft, the elastic element 25 is arranged on the upper support arm 24 and connected with the pull rod 28,

when the upper arm 24 and the lower arm 23 are unfolded relative to the base 1, the pull rod 28 rotates to abut against the push rod pin 29 under the elastic force of the elastic part 25, so as to limit the displacement of the push rod pin 29 in the sliding groove 27;

when the upper arm 24 and the lower arm 23 are folded with respect to the base 1, the pull rod 28 rotates to be parallel to the slide groove 27 and compresses the elastic member 25.

The working principle and process of the locking structure in this embodiment are the same as those of the locking structure in the previous embodiment, except that when in the locked state, as shown in fig. 4, the push rod pin 29 is located near one end of the slide groove 27 close to the base 1, while in the previous embodiment, as shown in fig. 2, the push rod pin 29 is located at one end of the slide groove 27 far from the base 1.

In order to enable the sliding groove 27 to still limit the displacement of the ejector pin 29 through the pull rod 28 when being opened on the upper arm 24, as shown in fig. 4, in the embodiment, the pull rod 28 has a bent portion 281, and when the upper arm 24 and the lower arm 23 are unfolded relative to the base 1, the pull rod 28 rotates under the elastic force of the elastic member 25 until the bent portion abuts against the ejector pin 29, so as to limit the displacement of the ejector pin 29 in the sliding groove 27.

As shown in fig. 2, when the sliding slot is formed on the lower arm, the elastic element 25 is a spring, one end of the pull rod 28 away from the ejector pin 29 is provided with a column, the spring is sleeved on the column, and two ends of the spring respectively abut against the lower arm 23 and the pull rod 28. The elastic element 25 may also be a torsion spring, which is sleeved on the third pin, and two legs of the torsion spring are fixedly connected with the pull rod 28 and the lower arm 23, respectively.

As shown in fig. 4, when the sliding slot 27 is opened on the upper arm 24, the elastic element 25 is a spring, one end of the pull rod 28 away from the pin 29 of the push rod is provided with a column, the spring is sleeved on the column, and two ends of the spring respectively abut against the upper arm 24 and the pull rod 28. The elastic element 25 may also be a torsion spring, which is sleeved on the third pin, and two legs of the torsion spring are fixedly connected with the pull rod 28 and the upper support arm 24, respectively.

As shown in fig. 2, since it is necessary to pull one end of the pull rod 28 to make the other end of the pull rod rotate to be offset from the push rod pin 29 in the unlocking process, in order to facilitate the pulling of the pull rod 28 to unlock, the locking structure in this embodiment further includes a pull lock rope 26, a first end of the pull lock rope 26 is fixedly connected to one end of the pull rod 28 far away from the push rod pin 29, and a second end of the pull lock rope passes through the side wall of the base 1 and extends. To facilitate the connection between the pull cord 26 and the pull rod 28, the pull rod 28 is formed with a pull hole, and a first end of the zipper cord 26 is fixedly disposed in the pull hole.
