[0043] The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples:

[0044] Reference Figure 17This is a schematic diagram of the unfolded structure of this embodiment. This embodiment mainly consists of a base frame, a ring beam, and an inclined beam. The ring beam is located at the top of the base frame, and the two are connected by the inclined beam. Both ends of the inclined beam are hinged to the ring beam and one section of the base frame via rotary joints. In summary and referring to... Figure 17 As can be seen, most of the space occupied by this storage structure needs to be allocated to the base frame. Therefore, in order to reduce the storage size, the base frame has been redesigned in this embodiment. Figures 1 to 9 The chassis in this embodiment is a U-shaped structure, including a front beam and two side beams; and the front beam and the two side beams are divided into segments, with each of the front beam and the side beams being divided into two segments.

[0045] The two sections of the front beam are named front beam a and front beam b, respectively; the two sections of the side beam are named side beam a and side beam b, respectively; because the underframe is a completely symmetrical structure, only some parts are described: including the connection between front beam a and front beam b, the connection between front beam a and side beam a, and the connection between side beam a and side beam b.

[0046] The structures at both ends of the front beam a are shown below. Figure 6 and Figure 7 ,in Figure 7 The insertion holes and pin holes of the front beam a correspond to each other. Figure 3 The elastic pin and the insertion end of the middle side beam a; the insertion end is inserted into the insertion hole. Since the elastic pin has a bevel, and the insertion hole also has a bevel, during the insertion process, due to the elasticity of the elastic pin, when the two bevels abut and slide relative to each other, the elastic pin retracts. After the insertion is in place, the elastic pin rebounds into the pin hole to achieve locking.

[0047] Figure 8 The elastic insert plate c and positioning post of the middle front beam a correspond to the front beam b respectively (see Figure 7 The slot c and positioning hole; the specific structure of the flexible insert c is shown in [reference needed]. Figure 9 The device includes a protrusion c. The elastic insert plate c of the front beam a is inserted downward from above the slot c of the front beam b. Due to the presence of the protrusion c (mainly its inclined surface), it will be subjected to a force towards the front beam a during the insertion process. When the insertion is in place, the elastic insert plate c rebounds, and the other side of the protrusion c abuts against the edge of the slot c to achieve locking. During the insertion of the elastic insert plate c, the positioning pin and the positioning hole cooperate to insert.

[0048] Both ends of the side beam a in this embodiment are Figure 3 The structure, specifically the connection end of side beam b, is shown in the following figure. Figure 5 The fitting method and connection process are the same as the insertion method of side beam a and front beam a. After insertion, it is locked by elastic pin and pin hole, which will not be described in detail here.

[0049] To further strengthen the connection structure between front beam a and front beam b, reinforcement holes and reinforcement plates are used. Reinforcement holes are provided at the connection between front beam a and front beam b, and on both front beam a and front beam b. The reinforcement plate spans across front beam a and front beam b, and a reinforcement post is provided on its back. The reinforcement post is inserted into the reinforcement hole and can be locked by a quick-lock screw that passes through both beams.

[0050] To maintain the stability of the two side beams b, the two ends of the crossbeam are respectively inserted into the two side beams b. In this embodiment, the crossbeam also consists of two parts, crossbeam a and crossbeam b. The assembly method and installation process of crossbeam a and crossbeam b are the same as those of front beam a and front beam b, and will not be repeated here. Some structural details can be found in [reference needed]. Figure 4 : Elastic insert plate and positioning post installed on front beam a.

[0051] The base frame in this embodiment provides support, and its bottom is equipped with four hinged legs and four insertion holes, four of which can be used to install casters. The distribution of the hinged supports and insertion holes is detailed in [reference needed]. Figure 2 .

[0052] To further achieve a smaller storage volume, upper and lower rotary joints are used, allowing the ring beam and inclined beam to lie in the same plane after folding. (Refer to...) Figures 10 to 16 The specific structure of the rotary joint is as follows:

[0053] Both the upper and lower rotary joints include a locking wheel, a support member, and a hinge member. The inner side of the support member and the inner side of the hinge member are provided with a locking groove. The locking grooves of the support member and the hinge member are interlocked to form a locking cavity. The locking wheel is located in the locking cavity. A rotating shaft is provided at the center of the locking groove of the support member, and the locking wheel is fitted on the rotating shaft. Both the locking wheel and the hinge member have the degree of freedom to rotate relative to each other along the rotating shaft. The annular wall of the locking groove is provided with a tooth groove, and the locking wheel is provided with locking teeth extending along its diameter direction, with the locking teeth located in the corresponding tooth grooves.

[0054] The hinge has a button on its outer side that passes through a through hole into its locking groove; the inner end of the button abuts against one surface of the locking wheel; a spring is installed in the locking groove of the support, with one end of the spring abutting against the other surface of the locking wheel. When the upper or lower rotary joint needs to rotate, the button is pressed, the inner end of the button presses against the locking wheel, the spring is compressed, the locking wheel is pressed into the locking groove of the support, and the locking teeth on the locking wheel disengage from the tooth groove of the hinge. At this time, a rotational force is applied to the support and the hinge, bringing them to the appropriate relative rotational position. When the button is released, the spring rebounds, the locking wheel spans across the support and the hinge, and the locking teeth are engaged in the tooth grooves of both to prevent rotation; in the locked state, part of the locking teeth of the locking wheel is located in the tooth groove of the support, and the other part is located in the tooth groove of the hinge.

[0055] The upper rotary joint is installed at the top of the inclined beam to connect the inclined beam to the ring beam, while the lower rotary joint is installed at the bottom of the inclined beam to connect the inclined beam to the base frame. The hinge of the upper rotary joint is an integral part of the inclined beam, and the support is connected to the ring beam via a quick-release plug-in structure a. The support of the lower rotary joint is an integral part of the inclined beam, and the hinge is an integral part of the base frame. Therefore, when the rotary joint is in the unlocked state, multi-angle rotation can be achieved by applying a rotational force to the inclined beam or ring beam. The rotation angle is related to the number of tooth grooves, and the rotation position locking is related to the tooth groove positions.

[0056] For details on the plug-in structure a, please refer to [link / reference]. Figure 10 and Figure 16 , Figure 16 This is a schematic diagram of the bottom structure of the ring beam. The outer side of the support member has a slot a, and one side of the slot a has an opening a; the bottom of the ring beam has an elastic insert plate a, and the elastic insert plate a has a protrusion a; the elastic insert plate a is inserted into the slot a, and the protrusion a abuts against the edge of the opening a; a vertical positioning structure is provided on the side of the insertion structure, the specific structure of which is described in detail. Figure 16 The corresponding prism ( Figure 16 Both sides of the flexible insert plate a) and the prism hole ( Figure 13 (Both sides of slot a), the prisms are inserted into the prism holes.

[0057] In summary, the ring beam in this embodiment can be kept in close contact with the base frame or stored within the area enclosed by the base frame via a rotating joint. Furthermore, the base frame can be disassembled into a segmented structure for further storage; the inclined beam and ring beam are separated via a plug-in structure a, making storage easier and reducing the overall storage volume.

[0058] The parts of this utility model not described in detail are techniques that belong to those skilled in the art.

[0059] The above description is merely a preferred embodiment of this utility model, intended to further illustrate the utility model, and not to limit it. Any simple substitutions made based on the content disclosed in the above text and drawings are within the scope of protection of this patent.
