Examples

[0019] Referring to FIGS. 1 to 3, FIG. 1 is a cross-sectional view of the connection structure of the removable storage shelf, FIG. 2 is an exploded view of the connection structure of the removable storage shelf, and FIG. 3 is a schematic view of the first pipe body and the second pipe body. This embodiment provides a connection structure for a removable storage shelf, which includes a first pipe body 1, a second pipe body 2, a fastening module 3, and a sleeve 4. Among them, the first pipe body 1 includes a converging pipe 11 and a connecting pipe 12, and the converging pipe 11 is connected to one end of the connecting pipe 12. When connecting, the converging pipe 11 is inserted into the second pipe body 2 to removably connect the first pipe body 1 and the second pipe body 2. Further, at least one fastening hole 10 is provided in both the pipe wall of the converging pipe 11 and the pipe wall of the second pipe body 2. Note that the number of the fastening holes 10 may be one or more. When the number of the fastening holes 10 is two, the two fastening holes 10 may be installed at intervals or opposite to each other. When the number of the fastening holes 10 is more than two, each fastening hole 10 is installed at intervals. In this embodiment, two fastening holes 10 are provided in the pipe wall of the converging pipe 11, and the two fastening holes 10 are installed opposite to each other. Two corresponding fastening holes 10 are respectively provided in the pipe wall of one end of the second pipe body 2. When the converging pipe 11 is connected to the second pipe body 2, one end of the second pipe body 2 is fitted outside the converging pipe 11, and the two fastening holes 10 of the second pipe body 2 correspond to the two fastening holes 10 of the converging pipe 11. When the fastening module 3 is connected to the second pipe body 2 and the converging pipe 11, the fastening holes 10 of the converging pipe 11 and the second pipe body 2 are drilled. Installed in this way, through the cooperation of the fastening holes 10 and the fastening module 3, the connection between the converging pipe 11 and the second pipe body 2 is further strengthened, the detachment of the converging pipe 11 and the second pipe body 2 is avoided, thereby realizing a stable connection between the first pipe body 1 and the second pipe body 2. The sleeve 4 is fitted outside the fastening module 3. The sleeve 4 is fastened to the first pipe body 1 and the second pipe body 2 by the fastening module 3, and the sleeve 4 maintains the fixation with respect to the first pipe body 1 and the second pipe body 2. Further, the sleeve 4 is fitted outside the connection portion between the first pipe body 1 and the second pipe body 2 to increase the support for the connection portion between the first pipe body 1 and the second pipe body 2. When the first pipe body 1 and the second pipe body 2 are shaken under the action of an external force, the sleeve 4 plays a role in strengthening the connection between the first pipe body 1 and the second pipe body 2, and further improves the stability of the connection between the first pipe body 1 and the second pipe body 2.

[0020] When it is necessary to remove the connection structure, move the sleeve 4 in a direction away from the fastening module 3 to disconnect the sleeve 4 from the connection with the fastening module 3. Then remove the fastening module 3 and disengage the fastening end 30 of the fastening module 3 from the fastening hole 10. Finally, remove the converging pipe 11 of the first pipe body 1 from the second pipe body 2 to complete the removal of the connection structure. Installed in this way, the connection structure realizes a detachable connection, thereby facilitating the storage and transportation of the storage shelf in the actual application scenario.

[0021] Furthermore, the outer diameter of the converging pipe 11 is less than or equal to the inner diameter of the second pipe body 2. When the first pipe body 1 is connected to the second pipe body 2, the converging pipe 11 can enter the second pipe body 2. In this example, the outer diameter of the converging pipe 11 is equal to the inner diameter of the second pipe body 2, and the outer wall of the converging pipe 11 is in close contact with the inner wall of the second pipe body 2 to stably connect the first pipe body 1 and the second pipe body 2.

[0022] Furthermore, the outer diameter of the connecting pipe 12 is equal to the outer diameter of the second pipe body 2. When the first pipe body 1 is connected to the second pipe body 2, the converging pipe 11 of the first pipe body 1 enters the second pipe body 2, and the connecting pipe 12 is joined to the end of the second pipe body 2. Since the connecting pipe 12 is equal to the outer diameter of the second pipe body 2, when the first pipe body 1 is connected to the second pipe body 2, the surface of the connection part of both is flat, facilitating the connection between the fastening module 3 and the first pipe body 1 and the second pipe body 2.

[0023] Referring to FIGS. 4 and 5, FIG. 4 is an exploded view of the fastening module, and FIG. 5 is a cross-sectional view of the fastening module. The fastening module 3 includes a first fastening member 31 and a second fastening member 32. Among them, the first fastening member 31 includes a first surrounding wall 311 and a first fastening part 312, and the first fastening part 312 is installed inside the first surrounding wall 311. The second fastening member 32 includes a second surrounding wall 321 and a second fastening part 322, and the second fastening part 322 is installed inside the second surrounding wall 321. In use, the first surrounding wall 311 and the second surrounding wall 321 are engaged with each other, and the first fastening part 312 and the second fastening part 322 sequentially penetrate the fastening holes 10 of the second pipe body 2 and the converging pipe 11.

[0024] In this embodiment, two engaging holes 10 are provided in both the tube wall of the converging tube 11 and the tube wall of the second tube body 2. The two engaging holes 10 in the tube wall of the converging tube 11 are arranged oppositely, and the two engaging holes 10 in the tube wall of the second tube body 2 are arranged oppositely. When the first tube body 1 is connected to the second tube body 2, the engaging holes 10 of the converging tube 11 and the engaging holes 10 of the second tube body 2 correspond to each other. In the actual use scenario, the first engaging portion 312 of the first engaging member 31 gradually enters the engaging hole 10 on one side of the second tube body 2 and the converging tube 11, and the inner side of the first surrounding wall 311 abuts against the outer wall of the second tube body 2. Then, the second engaging portion 322 of the second engaging member 32 is inserted into the engaging hole 10 on the other side of the second tube body 2 and the converging tube 11 to reinforce the stable connection between the second tube body 2 and the converging tube 11. The first surrounding wall 311 and the second surrounding wall 321 are engaged with each other, are provided around the connection portion between the first tube body 1 and the second tube body 2, and provide support for the connection portion between the first tube body 1 and the second tube body 2.

[0025] Furthermore, a first engaging structure 3110 is provided at the edge of the first surrounding wall 311, a second engaging structure 3210 is provided at the edge of the second surrounding wall 321, and the first engaging structure 3110 and the second engaging structure 3210 match each other. When the first engaging member 31 abuts against the second engaging member 32, the first engaging structure 3110 is fitted into the second engaging structure 3210 to realize the accurate connection between the first engaging member 31 and the second engaging member 32.

[0026] Moreover, the inner diameter of the engaging module 3 is equal to the outer diameter of the second tube body 2. When the engaging module 3 is connected to the first tube body 1 and the second tube body 2, the inner wall of the engaging module 3 is in close contact with the connecting tube 12 of the first tube body 1 and the outer wall of the second tube body 2 to avoid the detachment of the engaging module 3.

[0027] In addition, the fastening module 3 has a first end 33 and a second end 34, and along the direction approaching the second end 34 from the first end 33, the outer diameter of the fastening module 3 gradually increases. The sleeve 4 has a third end 41 and a fourth end 42, and along the direction approaching the fourth end 42 from the third end 41, the inner diameter of the sleeve 4 gradually increases. And the minimum inner diameter of the sleeve 4 is less than or equal to the minimum outer diameter of the fastening module 3, and the maximum inner diameter of the sleeve 4 is smaller than or equal to the maximum outer diameter of the fastening module 3. In this example, the minimum inner diameter of the sleeve 4 is smaller than the minimum outer diameter of the fastening module 3, and the maximum inner diameter of the sleeve 4 is smaller than the maximum outer diameter of the fastening module 3. When the sleeve 4 is connected to the fastening module 3, the fourth end 42 of the sleeve 4 is fitted outside the fastening module 3 along the direction towards the second end 34 of the first end 33 of the fastening module 3, the first end 33 of the fastening module 3 is fastened to the inner wall of the sleeve 4, and the outer wall of the fastening module 3 is attached to the inner wall of the sleeve 4, thereby generating a frictional force between the sleeve 4 and the fastening module 3 and tightly connecting the sleeve 4 to the fastening module 3. When an external force is applied to the sleeve 4, an interaction force is generated between the sleeve 4 and the fastening module 3. The greater the force applied to the sleeve 4, the tighter the connection between the sleeve 4 and the fastening module 3. In this way, the force-bearing capacity of the connection structure of the storage shelf is improved, and in the actual application scenario, the load-bearing strength of the storage shelf is effectively improved.

[0028] In one embodiment, at least one engaging hole 10 is formed at one end of the connecting pipe 12 away from the converging pipe 11. In this example, two engaging holes 10 are formed at one end of the connecting pipe 12 away from the converging pipe 11, and the number of engaging holes 10 in the connecting pipe 12 is made to match the number of engaging holes 10 in the converging pipe 11. The mutual connection of the two first pipe bodies 1 is achieved by inserting the converging pipe 11 of one first pipe body 1 into the connecting pipe 12 of the other first pipe body 1. By forming the first pipe body 1 as a standard member, the processing and production of the connection structure of the storage shelf are facilitated, the production efficiency is improved, and it is also easy to install. In an actual application scenario, by increasing the corresponding number of first pipe bodies 1, engaging modules 3 and sleeves 4, the stacking of the number of layers of the storage shelf can be realized. In this way, it is easy for the user to perform DIY settings on the storage shelf according to different needs, diversify the usage forms of the storage shelf, and the storage shelf can be applied to more scenarios.

[0029] Furthermore, at least one engaging hole 10 is formed at one end of the second pipe body 2 away from the first pipe body 1. In this example, two engaging holes 10 are formed at one end of the second pipe body 2 away from the first pipe body 1, and the number of engaging holes 10 at one end of the second pipe body 2 away from the first pipe body 1 is made to match the number of engaging holes 10 at the other end of the second pipe body 2. By installing the engaging hole 10 at one end of the second pipe body 2 away from the first pipe body 1, one end of the second pipe body 2 away from the first pipe body 1 can also be connected to the engaging member 3 and the sleeve 4.

Embodiment

[0030] This embodiment provides a storage shelf, which includes at least three sets of detachable connection structures of the storage shelf and further includes at least one storage frame 5. Each set of detachable connection structures of the storage shelf includes a first pipe body 1, a second pipe body 2, a fastening module 3 and a sleeve 4. The connection methods of the first pipe body 1, the second pipe body 2, the fastening module 3 and the sleeve 4 are the same as those in Embodiment 1, and will not be described one by one here. The difference between this embodiment and Embodiment 1 is that at least three sleeves 4 are further connected to the storage frame 5, each storage frame 5 is fastened to three fastening modules 3 by three sleeves 4, and the storage frame 5 holds the fixation for three sets of connected first pipe bodies 1 and second pipe bodies 2.

[0031] Referring to FIG. 6, FIG. 6 is a schematic diagram of the storage shelf in this embodiment. In this embodiment, taking four sets of connection structures of the storage shelf as an example, the four sets of connection structures of the storage shelf are respectively installed at the four corners of the storage frame 5, and the sleeves 4 of each set of connection structures of the storage shelf are connected to the four corners of the storage shelf 5. Each sleeve 4 is fastened to a fastening module 3 connected to the first pipe body 1 and the second pipe body 2, so that the storage frame 5 is connected to the four sets of connection structures of the storage shelf.

[0032] Furthermore, in order to increase the number of layers of the storage shelf, the storage shelf in this example includes four sets of connection structures of the storage shelf and further includes eight fastening modules 3, eight sleeves 4 and two storage frames 5. One fastening module 3 is connected to one end of the connection pipe 12 of the first pipe body 1 of each set of connection structures of the storage frame away from the converging pipe 11, and a fastening module 3 is similarly connected to one end of the second pipe body 2 away from the first pipe body 1. Sleeves 4 are respectively connected to the four corners of each storage frame 5. The sleeve 4 is used to connect the storage frame 5 to the fastening module 3 on the support column 6. Through the fastening of the sleeve 4 and the fastening module 3, the fixed connection between the storage frame 5 and the support column 6 is realized.

[0033] During connection, each storage frame 5 is respectively fitted outside four sets of attachment modules 3 at the same height on the support column 6 by four sleeves 4. Each sleeve 4 is attached corresponding to one attachment module 3, realizing a stable connection between the storage frame 5 and the support column 6. When placing articles in the storage frame 5, an interaction force is generated between the sleeve 4 and the attachment module 3, and the greater the weight of the placed articles, the greater the interaction force generated between the sleeve 4 and the attachment module 3. In this way, the load-bearing capacity of the storage shelf is effectively improved. In this way, by sequentially connecting three storage frames to the attachment modules installed on the support column, the assembly of the storage shelf is completed.

[0034] When transporting the storage shelf, remove the connection structure and separate the first pipe body 1 and the second pipe body 2 from each other. Since the length of the support column 6 becomes shorter, the first pipe body 1 and the second pipe body 2 can be accommodated inside the storage frame 5, protecting the first pipe body 1 and the second pipe body 2 and avoiding the first pipe body 1 and the second pipe body 2 from being damaged by colliding with external forces during transportation.

[0035] As described above, the converging pipe 11 of the first pipe body 1 is inserted into one end of the second pipe body 2 to connect the first pipe body 1 and the second pipe body 2. By respectively opening the attachment holes 10 on the pipe wall of the converging pipe 11 and the pipe wall of the second pipe body 2, when the converging pipe 11 is connected to the second pipe body 2, the attachment holes 10 provided on the converging pipe 11 and the attachment holes 10 provided on the second pipe body 2 correspond to each other. The attachment module 3 is attached to the attachment holes 10 of the second pipe body 2 and the converging pipe 11 to avoid the separation of the first pipe body 1 and the second pipe body 2. Moreover, the sleeve 4 is fitted outside the attachment module 3, and the sleeve 4 is attached to the attachment module 3, holding the sleeve 4 relatively fixed to the first pipe body 1 and the second pipe body 2, and moreover increasing the support for the connection location between the first pipe body 1 and the second pipe body 2.

[0036] 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 substitutions, 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.
