[0002] With the development of society, people are more and more demanding about the storage of daily necessities, and the convenience and practicality of the storage structure has always been pursued at the beginning of the design. For example, a rotating chair is provided on the legs of the existing table, and the storage and deployment of the chair is realized through the rotating structure. However, the existing rotating chairs generally include two types: the first type adopts a rotation method of thread adjustment, which requires higher precision in design and is prone to the problem of misadjustment when deployed; the second type is to fix a positioning shaft with a screw, and set a sleeve outside the positioning shaft to rotate the chair. This method is prone to the problem of screw loosening during use, which may cause damage to the equipment.

[0003] In summary, the existing technologies all have some problems and need to be improved. Utility Model Content

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0022] Example:

[0023] like Figure 1-Figure 5 As shown, this embodiment provides a storage structure, including a positioning column 1 (such as the legs of a table), an upper mounting seat 2 and a lower mounting seat 3 are installed on the positioning column 1 (the upper mounting seat 2 and the lower mounting seat 3 are both installed on the inner side of the table, which does not affect the use experience of the table), a positioning shaft 4 is detachably connected between the upper mounting seat 2 and the lower mounting seat 3 to ensure the stability of the positioning shaft 4, a rotating sleeve 5 is rotatably connected to the positioning shaft 4, and a connecting rod 6 connected to the stored object (such as a stool) is fixed on the rotating sleeve 5, so that the rotating sleeve 5 can be rotated around the positioning shaft 4, thereby realizing the storage object (such as a stool) being moved. The rotating sleeve 5 can be adjusted in height during rotation, so as to realize the height adjustment of the stored objects (such as stools), and the stored objects (such as stools) can be easily unfolded for use, or stored, which can also save a lot of space; the upper end of the lower mounting seat 3 is provided with an arc-shaped supporting surface, and the lower end of the rotating sleeve 5 is provided with an arc-shaped supporting portion 501, and the arc-shaped supporting portion 501 surface is in contact with the arc-shaped supporting surface. By setting the height of the arc-shaped supporting surface, the height adjustment of the rotating sleeve 5 during rotation can be realized, and then the height adjustment of the stored objects (such as stools) can be realized, so that the stored objects (such as stools) can be easily realized when unfolded and just fall to the ground.

[0024] The present invention makes the structure easy to load and unload by detachably connecting the positioning shaft 4 between the upper mounting seat 2 and the lower mounting seat 3, and thus facilitates later maintenance. Among them, the rotation adjustment of the stored object (such as a stool) directly modifies the original thread adjustment method into a natural rotation adjustment, and only provides a high and low support position by setting an arc-shaped supporting surface at the upper end of the lower mounting seat 3. This makes it more convenient to control the height of the stored object (such as a stool) in the use state and the storage state, making the design of the overall structure simpler and making it easier to meet the requirements of precision.

[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that a lower positioning groove is provided at the upper end of the lower mounting seat 3, and a first through hole is provided in the middle of the upper mounting seat 2. The first through hole is coaxially arranged with the lower positioning groove, and the positioning shaft 4 passes through the first through hole and is matched and inserted into the lower positioning groove. Therefore, when installing the positioning shaft 4, it only needs to be inserted between the upper mounting seat 2 and the lower mounting seat 3 from top to bottom, which is simple and convenient to operate.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that at least one positioning hole 301 is provided on the inner bottom surface of the lower positioning groove, and a positioning protrusion is provided on the lower part of the positioning shaft 4, which is matched and inserted into the positioning hole 301. Then, the positioning protrusion is limited by the positioning hole 301, so that the positioning shaft 4 can be prevented from rotating, thereby ensuring the stability of the positioning shaft 4.

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that an annular limit groove is provided on the inner wall of the lower part of the first through hole, and a spring piece 401 is cut on the outer wall of the upper part of the positioning shaft 4. The lower end of the positioning shaft 4 is integrally connected to the positioning shaft 4, and the upper part of the positioning shaft 4 protrudes toward the outside of the positioning shaft 4 and is clamped on the inner top surface of the annular limit groove. In this way, when the positioning shaft 4 is plugged in, the spring piece 401 on the positioning shaft 4 can just be clamped in the annular limit groove to ensure the stability of the positioning shaft 4; an adjustment hole 201 is provided on the upper mounting seat 2 corresponding to the spring piece 401, which is convenient for passing a screwdriver or the like through the adjustment hole 201 to support the spring piece 401, so that the spring piece 401 contracts, and then the positioning shaft 4 is taken out, thereby realizing rapid disassembly of the equipment.

[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower end of the rotating sleeve 5 is provided with two arc-shaped support parts 501 symmetrically distributed on both sides of the rotating sleeve 5, and the arc-shaped support surface at the upper end of the lower mounting seat 3 includes a first arc-shaped trough support surface, a second arc-shaped trough support surface, a first arc-shaped trough support surface and a second arc-shaped trough support surface sequentially opened on the same circumferential surface, wherein the two first arc-shaped trough support surfaces are symmetrically arranged, and the two second arc-shaped trough support surfaces are symmetrically arranged, and the adjacent first arc-shaped trough support surfaces and the second arc-shaped trough support surfaces are connected by the arc-shaped trough support surface; the curvature of the first arc-shaped trough support surface is the same as the curvature of the second arc-shaped trough support surface, and the depth of the first arc-shaped trough support surface is greater than the depth of the second arc-shaped trough support surface. If the arc-shaped support surface is fully unfolded on a plane, then as shown Figure 5 As shown, when the arc-shaped support portion 501 is supported on the first arc-shaped trough support surface, the stored object (such as a stool) is in an unfolded state, which is convenient for using the stored object (such as sitting on the stool); when the arc-shaped support portion 501 is supported on the second arc-shaped trough support surface, the stored object (such as a stool) is in a stored state.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that the positioning shaft 4 is a hollow sleeve structure, which saves more materials and makes the production of the spring piece 401 simpler.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower end of the positioning shaft 4 is provided with a threaded hole connected to the lower mounting seat 3 through a locking bolt, and the middle part of the lower mounting seat 3 is provided with a bolt mounting hole. The screw section of the locking bolt passes through the bolt mounting hole and is threadedly connected to the threaded hole. In this way, the positioning shaft 4 can be made more stable.

[0031] As a preferred implementation scheme in this embodiment, it should be further explained that the upper end of the positioning shaft 4 is a tapered head with a diameter that gradually decreases from bottom to top, and the diameter of the tapered head at the lowest end is larger than the inner diameter of the first through hole of the upper mounting seat 2. This allows the positioning shaft 4 to be clamped between the upper mounting seat 2 and the lower mounting seat 3, thereby ensuring the stability of the positioning shaft 4. It should be noted that during the actual installation process, the positioning shaft 4 can be installed first and then the upper mounting seat 2, or the positioning shaft 4 can be installed between the upper mounting seat 2 and the lower mounting seat 3 and then expanded. This embodiment does not impose any specific restrictions.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
