DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0032] In order to better understand the specific application and implementation of the box support structure proposed in this application, the specific scheme of the folding box table is first described in detail: Figure 1-7 As shown, the folding box table mainly includes an upper frame 1 and a lower frame 2, the lower frame 2 is provided with a surrounding support panel 3, and a foldable side panel 4 is provided between the support panel 3 and the upper frame 1. The foldable side panel 4 can be unfolded into a roughly flat surface to support the upper frame 1 to form an unfolded state, or folded into the inside of the folding box table so that the upper frame 1 is close to the support panel 3 to form a folded state.

[0033] Specifically, the foldable side panel 4 includes an upper side panel 41, a lower side panel 42, and a support column 43. The upper side panel 41 and the lower side panel 42 may be an integral piece or may be formed by splicing a plurality of profiles.

[0034] Among them, the support column 43 is arranged at the four ends of the folding box table, the lower end of the lower side panel 42 is hinged to the lower frame 2, one side of the upper end is hinged to the lower end of the support column 43, the upper end of the support column 43 is hinged to the upper frame 1, and the upper side panel 41 is placed between the two support columns 43 and hinged to the upper frame 1.

[0035] The folding box table can also be used as a table, which is achieved through the following solution: A support rod 411 that can be rotated to be folded or unfolded is provided on the inner wall of the upper side plate 41. A limit hole 421 for inserting the end of the support rod 411 is provided at the upper end of the lower side plate 42. The upper side plate 41 can be unfolded to be substantially flush with the plane formed by the upper frame 1, and the unfolded upper side plate 41 is supported by inserting the unfolded support rod 411 into the limit hole 421.

[0036] In this regard, it further includes an upper support plate 5. The upper support plate 5 includes at least two pieces, which are symmetrically hinged inside the upper frame 1 to form a split arrangement. When used as a table, at least three side edges of the upper support plate 5 are built on the upper frame 1 to be used as a tabletop. When used as a box, the upper support plate 5 can be opened outward relatively to facilitate taking and placing items.

[0037] To improve the support reliability, the lower frame 2 includes a plurality of support pieces 21. Some of the support pieces 21 are used for hinging with the lower side plate 42, and the remaining support pieces 21 are used for supporting the unfolded lower side plate 42. At the same time, these support pieces 21 also play the role of reinforcing ribs. Specifically, the lower frame 2 is generally in a U-shape, and the support pieces 21 are arranged in this groove of the lower frame 2, for example, fastened by screws.

[0038] For the folding box table as described above, the rotatable side plates form two of the sides of the box. For the remaining two sides and the bottom surface, it is achieved through the following solution: It further includes at least three seat units 6. The seat unit 6 includes a seat surface 61 and chair legs 62 that can be folded or unfolded. When the folding box table is in the unfolded state, the seat unit 6 is combined inside the folding box table to form the sides and the bottom surface of the folding box table, or separated from the folding box table. When the folding box table is in the folded state, the seat unit 6 is stacked and stored inside the folding box table. In this way, the seat unit 6 plays two functional effects, greatly improving the structural utilization rate.

[0039] When the folding box table is in the folded state, two layers of seat units 6, the lower side plate 42, and the upper side plate 41 are stacked inside the folding box table from bottom to top in sequence.

[0040] Furthermore, there are four seat units 6. When the folding box table is in the unfolded state, two of them can be selectively arranged between two symmetrically foldable side plates 4 as side plates, and the remaining two can be selectively arranged on the lower frame 2 as a bottom plate.

[0041] A support frame 7 for supporting and limiting the lower part of the seat unit 6 is provided on the lower frame 2, and a locking member 8 for locking the upper part of the seat unit 6 is provided on the upper frame 1.

[0042] Specifically, the seat surface 61 of the seat unit 6 includes a side wall 611, and the support frame 7 includes a first limiting groove 71 and a second limiting groove 72, wherein the first limiting groove 71 is strip-shaped and the second limiting groove 72 is arc-shaped, wherein the side wall 611 of the seat surface 61 is inserted into the first limiting groove 71, and the rotating rod 621 is placed on the second limiting groove 72; the locking member 8 is used to lock the side wall 611 at the upper end of the seat surface 61. A spacing is also formed between the support frame 7 and the lower frame 2 to facilitate the insertion of the seat unit 6 and provide a limiting function for it.

[0043] A locking structure 9 is provided between the upper frame 1 and the supporting panel 3 for locking the folding table when it is in a folded state. The locking structure 9 can be various, for example, fasteners are respectively installed between the upper frame 1 and the supporting panel 3, and the two can be locked or unlocked.

[0044] Reference Figure 8-9 As shown, a box board support structure of a folding box table will be further explained below, and the box board support structure serves as the side and bottom surfaces of the folding box table.

[0045] Specifically, the seat unit 6 is combined in a folding box table and used as a box board supporting structure of the folding box table, or is separated from the folding box table and used independently.

[0046] Secondly, the chair leg 62 includes a rotating rod 621 and a supporting leg 622, the rotating rod 621 is hingedly arranged on the chair seat 61, and a rotatable and self-resetting locking structure 63 is arranged on one side close to the rotating rod 621, and the locking structure 63 is used to lock the relative angle of the chair leg 62 with respect to the chair seat 61, so as to realize the unfolding or folding.

[0047] Furthermore, a support member 64 is provided on the back of the seat surface 61, the two ends of the support member 64 form a first connection part 641, the middle end of the support member 64 forms a second connection part 642, the rotating rod 621 is rotatably set on the two first connection parts 641, and the locking structure 63 is rotatably set on the second connection part 642.

[0048] Regarding the specific setting of the locking structure 63: the locking structure 63 includes a rotating shaft 631, a torsion spring 632, and a locking piece 633. The locking piece 633 includes a pressing portion 6331 and an inserting portion 6332. The rotating rod 621 is provided with locking holes 6211 located at different positions on the circumference. The locking piece 633 is installed on the second connecting portion 642 through the rotating shaft 631 and can rotate. The torsion spring 632 is sleeved on the rotating shaft 631 to keep the inserting portion 6332 of the locking piece 633 close to the rotating rod 621 and to insert the inserting portion 6332 into the locking holes 6211 at different positions, so that the chair leg 62 is in a folded or unfolded state. The pressing portion 6331 is used to release the locking of the rotating rod 621 by the inserting portion 6332.

[0049] For some other improved embodiments, a groove 612 is formed on the front of the seat surface 61, and a rotatable handle 613 is arranged in the groove 612. In this way, the folding box table can be conveniently carried.
