Instead, they are only for the purpose of distinguishing modules or operations described with the same technical terms, and it cannot be understood that they indicate or imply the relative importance or imply the number of technical features indicated. Thus, the features limited by "first" and "second" can explicitly or implicitly include at least one of such features. Also, the technical solutions between each embodiment can be combined with each other, but those skilled in the art must be based on what can be realized. If the combination of technical solutions conflicts with each other or cannot be realized, such a combination of technical solutions should be considered non-existent and not within the scope of protection required by the present invention.

[0020] Referring to FIGS. 2 and 3, FIG. 2 is a schematic view of the connection structure of a storage shelf, and FIG. 3 is a fitting schematic view of the connection structure of the storage shelf. This embodiment provides a connection structure for a storage shelf, which includes a support column 1, a fastening cylinder 2, a connection cylinder body 3, and a connection member 4. The fastening cylinder 2 is fitted outside the support column 1, the connection cylinder body 3 is fitted outside the fastening cylinder 2, the fastening cylinder 2 is fastened between the support column 1 and the connection cylinder body 3, and the connection cylinder body 3 is held so as to be fixed to the support column 1.

[0021] The connection cylinder body 3 includes a main body 30 and a mounting table 31, and the mounting table 31 is annularly provided at one end of the main body 30. When the connection cylinder body 3 is fitted into the fastening cylinder 2, the main body 30 is attached to the outer wall of the fastening cylinder 2.

[0022] Furthermore, the main body 30 presents a straight cylindrical shape. The connecting member 4 is also straight cylindrical. When the connecting member 4 is fitted and connected to the connecting cylinder body 3, the connecting member 4 is fitted outside the main body 30, and one end of the connecting member 4 abuts against the mounting table 31 of the connecting cylinder body 3. Thereby, the connecting cylinder body 3 provides support to the connecting member 4 and holds the connecting member 4 fixed to the support column 1.

[0023] Since the connecting cylinder body 3 is straight cylindrical, when the connecting member 4 is fitted to the connecting cylinder body 3, the connecting member 4 is fitted to the connecting cylinder body 3 from the opening at either one end. In actual application, the connecting member 4 can be fixed to the net frame, and the net frame can be attached to the support column 1 via the connecting member 4. In this way, the net frame can be attached to the support column 1 in either the forward or reverse direction. Thereby, the user can adjust the attachment direction of the net frame according to the usage needs, effectively improving the usability of the storage shelf.

[0024] Referring to FIG. 4, FIG. 4 is a cross-sectional view of the connecting cylinder body. Furthermore, the inner diameter of the main body 30 gradually increases along the direction approaching the mounting table 31, and the minimum inner diameter of the main body 30 is larger than the outer diameter of the support column 1. When the connecting cylinder body 3 is fitted to the support column 1, since the minimum inner diameter of the connecting cylinder body 3 is larger than the outer diameter of the support column 1, the connecting cylinder body 3 can be moved relative to the support column 1, making it easy to adjust the position of the connecting cylinder body 3 relative to the support column 1.

[0025] Furthermore, an adjustment groove 32 is opened on the side wall of the connecting cylinder body 3, and the adjustment groove 32 is installed along the longitudinal direction of the connecting cylinder body 3. By opening the adjustment groove 32, the inside of the connecting cylinder body 3 communicates with the outside air, keeping the internal and external pressures of the connecting cylinder body 3 consistent and making it easy to remove the connecting cylinder body 3 from the engaging cylinder 2.

[0026] In this embodiment, two adjustment grooves 32 are both opened on the side wall of the connecting cylinder body 3, and the two adjustment grooves 32 are installed opposite to each other.

[0027] Also, at one end of the main body 30 away from the mounting table 31, an inclined guide surface 33 for guiding the connection between the connecting member 4 and the connecting cylinder body 3 is annularly provided.

[0028] In order to facilitate the connection between the connecting member 4 and the connecting cylinder body 3, the inner diameter of the connecting member 4 is not less than the outer diameter of the connecting cylinder body 3. In this embodiment, the inner diameter of the connecting member 4 is equal to the outer diameter of the connecting cylinder body 3. When the connecting member 4 is fitted into the connecting cylinder body 3, a tight connection is maintained between the two to avoid loosening and dropping of the connecting member 4.

[0029] Also, the outer diameter of the connecting member 4 is not greater than the outer diameter of the mounting table 31. In this embodiment, the outer diameter of the connecting member 4 is equal to the outer diameter of the mounting table 31. When one end of the connecting member 4 abuts against the mounting table 31, the outer wall of the connecting member 4 is flush with the outer wall of the mounting table 31.

[0030] Furthermore, in order to achieve the fitting connection between the engaging cylinder 2 and the support column 1, the inner diameter of the engaging cylinder 2 is equal to the outer diameter of the support column 1, so that the engaging cylinder 2 can be slidably connected to the support column 1 and it is difficult for the engaging cylinder 2 to fall off.

[0031] Referring to FIG. 5, FIG. 5 is a cross-sectional view of the engaging cylinder. Furthermore, the engaging cylinder 2 has a first end 21 and a second end 22 which are oppositely arranged. The outer diameter of the engaging cylinder 2 gradually increases along the direction from the first end 21 to the second end 22. And the minimum outer diameter of the engaging cylinder 2 is greater than the minimum inner diameter of the connecting cylinder body 3, and the maximum outer diameter of the engaging cylinder 2 is greater than the maximum inner diameter of the connecting cylinder body 3. During installation, the engaging cylinder 2 is attached to the support column 1, and the engaging cylinder 2 is urged along the direction approaching the connecting cylinder body 3. Until the engaging cylinder 2 cannot be urged any further, its first end 21 is inserted into the connecting cylinder body 3, and the engaging cylinder 2 is locked between the connecting cylinder body 3 and the support column 1. Thereby, the connecting cylinder body 3 is firmly connected to the support column 1 via the engaging cylinder 2.

[0032] Furthermore, a vertical opening 200 is formed in the side wall of the engaging cylinder 2. When a force is applied to the engaging cylinder 2, the vertical opening 200 is pressed. When the force is removed, the vertical opening 200 returns to its original state, providing the engaging cylinder 2 with adjustability. In the actual use process, when no force is applied, the engaging cylinder 2 can freely adjust its position relative to the support column 1. When the engaging cylinder 2 is pressed by the connecting cylinder 3, the vertical opening 200 of the engaging cylinder 2 is tightened. This clamps the engaging cylinder 2 to the support column 1, realizing a firm connection among the engaging cylinder 2, the connecting cylinder body 3, and the support column 1.

[0033] Also, to achieve a firm connection between the engaging cylinder 2 and the support column 1, a plurality of annular grooves 11 are installed at intervals on the outer wall of the support column 1, and an engaging ring 23 is protruded on the inner wall of the second end 22 of the engaging cylinder 2, and the engaging ring 23 is fitted with the annular groove 11.

[0034] During installation, the engaging cylinder 2 is urged in the direction of the connecting cylinder body 3, and the engaging cylinder 2 is inserted into the connecting cylinder body 3. The engaging cylinder 2 is pressed by the connecting cylinder body 3, and the second end 22 of the engaging cylinder 2 is converged. At this time, the engaging ring 23 engages with the annular groove 11, fixing the engaging cylinder 2 to the support column 1.

[0035] This embodiment further provides a storage shelf including the above connection structure of the storage shelf.

[0036] In the actual application scenario, one connecting cylinder body 3 is respectively attached to the four support columns 1 of the storage shelf. Each connecting cylinder body 3 is fixed to the support column 1 via the engaging cylinder 2, and one connecting member 4 is respectively attached to the four corners of the net frame. When attaching the net frame to the support column 1, by fitting the four connecting members 4 on the net frame respectively corresponding to the connecting cylinder bodies 3 on the four support columns 1, the connection between the net frame and the support column 1 is realized. Also, the net frame can be selected to be attached in the positive direction or the reverse direction according to the user's needs. Compared with the conventional storage shelf using a tapered cylinder, the connection structure of the storage shelf of the present invention facilitates the installation of the storage shelf and can arbitrarily change the attachment direction of the net frame according to the use scenario, greatly varying the usage forms of the storage shelf.

[0037] The above are only embodiments of the present invention and do not limit the present invention. Those skilled in the art can make various changes and modifications to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should all be included within the scope of the claims of the present invention.
