DETAILED DESCRIPTION OF THE INVENTION

(9) To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

Embodiment 1

(10) The technical solution of this embodiment mainly solves the problem that a storage basket is inconvenient to transport and difficult to assemble due to its larger volume. Referring to FIG. 1 and FIG. 2, the present disclosure provides a foldable shelf convenient to transport and assemble, including at least two storage members 1 arranged in a vertical direction and vertical rods 2 installed on two sides of the storage members 1. The storage members 1 each may be a storage basket shown in FIG. 1, or may be a storage laminate board. As shown in FIG. 1, in this embodiment, the storage members 1 are preferably storage baskets, and three storage baskets are provided preferably. In addition, two sides of the storage members 1 each may be provided with one vertical rod 2 as shown in FIG. 1, or two sides of the storage members 1 each may be provided with two vertical rods 2. The number of the vertical rods 2 is related to shapes and sizes of the storage members 1.

(11) Specifically, referring to FIG. 1 to FIG. 3, in this embodiment, the vertical rods 2 each includes a fixed rod 21 and at least one folding rod 22. The fixed rod 21 is fixed to one side of the bottom storage member 1, and a lower end of one folding rod 22 adjacent to the fixed rod 21 is hinged to an upper end of the fixed rod 21. It should be noted herein that if the length of the vertical rod 2 is excessively large, two or more folding rods 22 may be provided. Every two adjacent folding rods 22 are hinged to each other to achieve the purpose of folding for many times and reduce the transportation volume. In addition, one end of the folding rod 22 hinged to the fixed rod 21 is provided with an avoidance notch 221. The avoidance notch 221 can solve the problem that the folding rod 22 interferes with the fixed rod 21 during folding.

(12) More specifically, referring to FIG. 1 and FIG. 2, the storage member 1 at the bottom is fixed to an inner side of the fixed rod 21, two sides of each of all the storage members 1 except the bottom storage member 1 are fixedly connected to sliding blocks 3, and the sliding blocks 3 each sleeve the vertical rod 2 and are capable of sliding along the fixed rod 21 on the vertical rod 2 and the folding rod 22. In addition, a fastening device 4 is disposed between the sliding block 3 and the folding rod 22, so that the sliding block 3 is fixed to the folding rod 22, and therefore each storage member 1 can be fixed to the vertical rod 2. The fastening device 4 may be a conventional screw locking device or a buckle connection device.

(13) Specifically, referring to FIG. 1 to FIG. 3, before delivery and transportation, fastening devices 4 are loosened first, so that sliding blocks 3 on two sides of each storage member 1 (that is, all storage members 1 except the bottom storage member 1) can slide down along the folding rods 22. After the sliding blocks 3 on two sides of the storage members 1 slide from folding rods 22 into fixed rods 21, because a lower end of each of the folding rods 22 is hinged to an upper end of one fixed rod 21, the folding rods 22 can be folded. After folding, the structural volume of the shelf is greatly reduced (as shown in FIG. 2), thereby facilitating subsequent transportation and reducing transportation costs.

(14) Referring to FIG. 1 to FIG. 3, when a user assembles the shelf of this technical solution, the folding rods 22 can be folded upward first to make the folding rods 22 and the fixed rods 21 in a vertical state. In this case, all storage members 1 except the bottom storage member 1 are separately lifted upward. In this case, the sliding blocks 3 on two sides of the lifted storage members 1 also slide from the fixed rods 21 to the folding rods 22, and then the sliding blocks 3 are fixed to the folding rods 22 by the fastening devices 4, so that all storage members 1 are in a relatively fixed state on the vertical rods 2 respectively, and in this case, the assembly of the shelf is completed (as shown in FIG. 1).

(15) The top of the shelf of this technical solution may be further provided with an armrest which facilitates pushing of the shelf, one end of the armrest is connected to the upper end of the vertical rod 2 on one side of the storage member 1, and the other end of the armrest is connected to the upper end of the vertical rod 2 on the other side of the storage member 1.

(16) In conclusion, the shelf of this technical solution can not only greatly reduce the transportation volume and transportation costs, but also facilitate assembly by the user. During assembly, the user only needs to first unfold the folding rods 22, then lift the storage members 1 upward, and finally uses the fastening devices 4 to fix the storage members 1, so that the installation operation can be completed. No professional person is required in the installation process. The shelf has the advantages of simple structure and low assembly difficulty.

(17) In addition, in this embodiment, it needs to be further noted that as shown in FIG. 2 and FIG. 3, when the sliding blocks 3 on two sides are oppositely arranged, there is a certain height difference between hinge points 9 at which the folding rods 22 on two sides are hinged to the fixed rods 21, so as to avoid mutual interference between the two folding rods 22 after folding. Certainly, referring to FIG. 4, the sliding blocks 3 on two sides may alternatively be staggered, which can also avoid mutual interference between the two folding rods 22 after folding.

Embodiment 2

(18) To further lower the installation difficulty, further improve installation efficiency and improve user experience, this embodiment provides another foldable shelf convenient to transport and assemble in which a fastening device 4 is designed as an automatic fastening device while the remaining structure is the same as that of Embodiment 1. Details are not described again.

(19) Specifically, referring to FIG. 1 to FIG. 3, the fastening device 4 is an elastic protruding point disposed on the folding rod 22, and the sliding block 3 is provided with a first positioning hole 31 matching the elastic protruding point. Specifically, during assembly by the user, the user first unfolds each folding rod 22, and then lifts each storage member 1 upward. When the storage member 1 reaches a designated position, the head of the elastic protruding point on the folding rod 22 is automatically embedded into the first positioning hole 31 in the sliding block 3, so as to implement fixed connection between the sliding block 3 and the folding rod 22, thereby completing the assembly process of the storage member 1. The fastening device 4 of this technical solution can further increase the user's assembly speed and improve user experience.

(20) Further, when at least two storage members 1 are provided, in this embodiment, each sliding block 3 is further provided with at least one avoidance hole 32. Through the avoidance hole 32, each sliding block 3 can be quickly lifted to a position of the elastic protruding point that matches and is positioned with the sliding block 3, and each sliding block 3 is not limited by the elastic protruding point below the sliding block 3. Certainly, as shown in FIG. 2, in this case, several elastic protruding points on the folding rod 22 should also be staggered.

Embodiment 3

(21) Referring to FIG. 5 and FIG. 6, the present disclosure provides another foldable shelf convenient to transport and assemble in which a fastening device 4 is designed as another automatic fastening device while the remaining structure is the same as that of Embodiment 1. Details are not described again.

(22) In this embodiment, the fastening device 4 includes a spring fixing seat 41, a top block 42, a spring 43, and a handle 44. The spring fixing seat 41 is fixed to an outer side of the sliding block 3, the top block 42 is installed on a middle portion of the spring fixing seat 41, the spring 43 is installed between the spring fixing seat 41 and the top block 42, one end of the spring 43 abuts against the spring fixing seat 41, the other end thereof abuts against the top block 42, and the handle 44 is fixed to the tail of the top block 42. In addition, the folding rod 22 is provided with a second positioning hole 40, and the tail of the spring fixing seat 41 is provided with a recessed groove 411.

(23) Specifically, before the user lifts each storage member 1, the handle 44 is separated from the groove 411 first, so that the top block 42 is in a retracting state in the spring fixing seat 41. After the storage member 1 is lifted to a proper position, the handle 44 is rotated to embed the handle 44 into the groove 411. In this case, the spring 43 drives the top block 42 to extend outward, and the head of the top block 42 is embedded into the second positioning hole 40 in the folding rod 22. Because the spring fixing seat 41 is relatively fixed to the sliding block 3, the fixed connection between the sliding block 3 and the folding rod 22 can be implemented, and the assembly of the storage member 1 is completed.

(24) The fastening device 4 of this technical solution can further increase the user's assembly speed and improve user experience.

Embodiment 4

(25) Referring to FIG. 1 and FIG. 2, this embodiment provides another foldable shelf convenient to transport and assemble on which each sliding block 3 may be a linear bearing. Certainly, in this case, the vertical rod 2 is round, and the remaining structure is the same as that of Embodiment 1. Details are not described again.

(26) In addition, as shown in FIG. 1 and FIG. 2, in this embodiment, the bottom of the bottom storage member 1 is provided with a base 5, and casters 6 are fixed around the bottom of the base 5. On the one hand, the base 5 functions to lower the center of gravity, and on the other hand, the base 5 also facilitates installation of several casters 6. The casters 6 are arranged to enable the user to easily move the shelf to a designated position, and further improve user experience.

(27) The foregoing embodiments are preferred implementations of the present disclosure, but the implementations of the present disclosure are not limited by the foregoing embodiments. Any other changes, modifications, replacements, combinations and simplifications made without departing from the spirit and principle of the present disclosure shall be equivalent replacement methods, and shall fall within the protection scope of the present disclosure.
