[0039] Embodiment 1

[0040] Reference Figure 1-11 As shown, this embodiment provides a folding cabinet, which includes a folding support structure 1 and a folding enclosure structure 2 surrounding the outer periphery of the folding support structure 1. Different from the traditional folding cabinet body that uses scattered parts for combined assembly, the folding support structure 1 and the folding enclosure structure 2 of the present utility model are both pre-folded integral connection structures, and the internal skeleton can be quickly supported and the external cabinet panel can be conveniently closed by the opening and closing of the overall structure. Specifically, the folding support structure 1 includes a first folding frame 11 that rotates and opens and closes around its own center line, and second folding frames 12 rotatably connected to both sides of the first folding frame 11. The mutual rotation of the first folding frame 11 and the second folding frames 12 can realize the switching of the folding support structure 1 between the storage state and the unfolded state.

[0041] The first folding frame 11 includes three longitudinal rods arranged at intervals in the height direction of the cabinet body and four cross rods 113 arranged horizontally. The four cross rods 113 are parallel up and down and are distributed between the three longitudinal rods. The longitudinal rods include the first longitudinal rods 111 at both sides and the second longitudinal rod 112 at the middle position. One end of the cross rod 113 is fixedly connected to the first longitudinal rod 111, and the other end is detachably connected to the second longitudinal rod 112 through a folding connector 115. The first folding frame 11 realizes the rotational opening and closing of the body through the folding connectors 115 symmetrically connected at the position of its own central axis. From the perspective of structural characteristics, in the unfolded state, the folding connector 115 is provided with a third interface 115-3 connecting the second longitudinal rod 112 in the height direction and two radial interfaces connecting the cross rods 113 on both sides in the horizontal direction. The openings of the two radial interfaces are arranged in reverse and are butted by rotating and fitting through a connecting shaft. The second folding frame 12 is rotatably connected to the upper and lower sides of the first folding frame 11 through the support rods 114 on the first folding frame 11. Since one end of the support rod 114 is rotatably connected to the first folding frame 11 and the other end is inserted and connected to the insertion interface 124-1 on the connecting component 124, and the connecting component 124 abuts against the long rod 122 on the second folding frame 12 to form the second folding frame 12. In view of the fact that the connecting component 124 plays a role of right-angle bending in the connection of the rods, that is, the two rod connection ports on the connecting component 124 are in a butting right angle. The connecting components 124 arranged on both sides of the first folding frame 11 are connected through the long rod 122, and the long rod 122 is propped between the opening and closing angles of the opening and closing of the first folding frame 11, playing a limiting and matching role against the opening and closing direction of the first folding frame 11. Since the connection fulcrum between the second folding frame 12 and the first folding frame 11 is the support rod, one end of the support rod is rotatably connected to one side of the first longitudinal rod 111 and the other end is inserted and connected to the insertion interface 124-1 on the connecting component 124. The rotational connection method enables a certain degree of opening and closing freedom between the second folding frame 12 and the first folding frame 11. However, as the skeleton support structure of the cabinet body, the connection between the first folding frame 11 and the second folding frame 12 needs to have a rigid flexibility. Obviously, when the frame body is supported, the relative positions of the first folding frame 11 and the second folding frame 12 need to be fixed. Therefore, in the present utility model, a socket for inserting the limiting rod 123 is provided on the side of the long rod 122. One end of the limiting rod 123 is inserted into the socket, and the other end is in a tight fit with the plug block 115-0 on the folding connector 115 to realize the relative fixation between the first folding frame 11 and the second folding frame 12.

[0042] The folding enclosure structure 2 is a panel combination unit made of plastic suction materials, which is characterized by being lightweight, high-strength and easy to carry. Its combination includes a back panel 21, side panels 22 rotatably connected to both sides of the back panel 21, and a front panel 23 pivotally connected to the side panels 22 through a rotating shaft 202. The folding enclosure structure 2 encloses and wraps the folding support structure 1 in the unfolded state, and inserts and connects the pin shafts at the upper and lower ends of the rotating shaft 202 into the shaft holes 124-2 on the connecting components 124 at the upper and lower positions, so that the back panel 21 and the side panels 22 can be stably attached to the three sides of the folding support structure 1, and the front panel 23 rotates and opens around the position where the fixed rotating shaft 202 is located. Upper end plates 31 are assembled at the top and bottom of the cabinet body, so that the whole cabinet body is enclosed to form a closed space for storing items. In addition, considering the need to effectively partition the internal space to place items, the present utility model is designed with an inward concave rib 201 along the enclosure direction of the folding enclosure structure 2, and the bottom of the shelf 33 for placing items is placed on the rib 201, which can not only make the installation position of the shelf 33 be flexibly distributed, but also has a lower assembly cost and a significantly improved assembly efficiency compared with the traditional way of fixing the shelf by using a bolt-anchoring assembly structure inside the cabinet.

[0043] Embodiment 2

[0044] Reference Figure 4 With Figure 6 As shown, this embodiment provides a folding connector 115, which includes a first support and a second support that are pivotally connected. The second rotating support rotates relative to the first rotating support to realize the switching of the folding connector 115 between the storage state and the unfolded state. Specifically, plug-in blocks 115-0 for limit cooperation are provided on both the first support and the second support. The plug-in blocks 115-0 are arranged at the overlapping ends of the two supports close to each other and are connected by a connecting shaft. When the folding connector 115 is opened, the two plug-in blocks 115-0 close together and protrude outwards, and are limit-fitted between the two supports against the rotation direction of the supports; when the folding connector 115 is retracted, the two supports rotate towards each other along the pivotal connection position, and drive the plug-in blocks 115-0 to retract inwards against the rotation direction.

[0045] As a rod connection support, from the perspective of structural connection, the first support is provided with a first interface 115-1 along the direction of its rotation plane, and the second support is provided with a second interface 115-2 along the direction of its rotation plane. When the folding connector 115 is opened, the opening directions of the first interface 115-1 and the second interface 115-2 are arranged in a reverse manner. When the second support rotates and drives the second interface 115-2 to approach the first interface 115-1, the folding connector 115 is folded. In addition, a third interface 115-3 perpendicular and fixedly connected to the first interface 115-1 is provided in the height direction of the first support. In the unfolded state, the first interface 115-1, the third interface 115-0, and the outwardly protruding insertion block 115-0 on the first support are pairwise perpendicular. When the second support drives the second interface 115-2 to rotate to the same direction as the first interface 115-1 with the connecting shaft as the axis, the insertion block 115-3 retracts inward against the rotation direction, and at this time, the folding connector 115 is in a folded state.

[0046] Embodiment 3

[0047] Reference Figure 4-8 As shown, a folding support structure 1 provided in this embodiment includes a first folding frame 11 that rotates and opens and closes around a folding component 115, and second folding frames 12 rotatably connected to both sides of the first folding frame 11. The first folding frame 11 and the second folding frames 12 rotate relative to each other to realize the switching of the folding support structure 1 between the storage state and the unfolded state.

[0048] The first folding frame 11 includes three longitudinal rods and four cross rods, and the three longitudinal rods are parallel to each other and connected by the cross rods. The longitudinal rods include first longitudinal rods 111 at both side positions and a second longitudinal rod 112 at the middle position. The end of the second longitudinal rod 112 is connected to the cross rods 113 on both sides through the folding component 115. A support rod 114 rotatably connected to one side of the first longitudinal rod 111 is inserted and connected to an insertion interface 124-1 at the end away from the first longitudinal rod 111, and is connected to the second folding frame 12 through a connection component 124.

[0049] The second folding frame 12 includes a long rod 122 and a limiting rod 123 inserted at one end into the long rod 122. The long rod 122 is limited and cooperated between the support rods 114 against the opening and closing direction of the first folding frame 11, and its two ends are axially connected to the connection component 124. A receiving socket for inserting the limiting rod 123 is provided on the side of the long rod 122. One end of the limiting rod 123 is inserted into the receiving socket, and the other end is in tight fit with the third radial joint 115-3 on the folding component 115 to limit the relative swing of the second folding frame 12 relative to the first folding frame 11.
