Description

Technical Field

[0001] This utility model relates to the technical field of storage racks, and more specifically to an expandable storage rack. Background Technology

[0002] Shelves are becoming increasingly popular in homes, serving as storage for a wide variety of small items. However, some existing shelves require wall mounting and occupy a large area, yet offer limited storage space. Furthermore, the overall frame and number of shelves cannot be flexibly expanded, and the height of each shelf cannot be adjusted as needed, resulting in wasted storage space. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an expandable storage rack that does not need to be installed against a wall, has a small overall footprint, and whose overall frame width, number of storage layers and height of each layer can be flexibly adjusted to maximize storage space.

[0004] The technical solution of this utility model is to provide an expandable shelf, including at least two spaced uprights, each upright having at least two sliding grooves extending along its length on its side; at least one shelf is provided between two adjacent uprights, each shelf having a rear connection hole and a front connection hole on its left and right sides; a connecting assembly is provided between the uprights and the shelf, the connecting assembly including a rear connecting slider, a front connecting slider, a pull rod, and a front connector, both the rear and front connecting sliders being slidably connected to the sliding grooves, the rear connecting slider having a rear insert rod inserted into the rear connection hole and locked with a nut, the two ends of the pull rod being connected to the front connecting slider and the front connector respectively, the front connector having a front insert rod inserted into the front connection hole and locked with a nut.

[0005] Compared with existing technologies, the expandable shelving unit of this utility model has the following advantages: it uses uprights as a frame, and only requires fixing the uprights for installation, eliminating the need for wall mounting. It has a small overall footprint, and the width of the overall frame can be adjusted by increasing or decreasing the number of uprights and adjusting the spacing between them. The number of storage layers can be increased or decreased by increasing or decreasing the number of shelving units. Furthermore, since the rear and front connecting sliders of the shelving units can slide along the grooves on the uprights to adjust the height, the height of each shelf can also be flexibly adjusted to accommodate the height of the stored items and maximize the storage space.

[0006] Preferably, the position of the front connecting slider on the column is higher than the position of the shelf on the column, the length of the pull rod is greater than the width of the shelf, and the pull rod is diagonally connected between the front connecting slider and the front connecting head. With this structure, the pull rod, the width of the shelf, and the part of the column located between the front connecting slider and the shelf form a right-angled triangle, which can keep the shelf stable on the column; the main force direction of the pull rod is the tensile force along the length of the pull rod, reducing the shear force applied to the pull rod and avoiding deformation of the pull rod.

[0007] Preferably, the front connecting slider is equipped with a rotating head seat, and one end of the pull rod is equipped with a connector, which is spherical and rotatably connected inside the rotating head seat. This structure allows the pull rod to easily rotate up and down to accommodate the width of the shelf.

[0008] Preferably, the connecting assembly includes a first connecting assembly and a second connecting assembly. The first connecting assembly has only one front connecting rod on its front connector and only one rear connecting slider, and is used to connect a single shelf. The second connecting assembly has two front connecting rods on its front connector and two rear connecting sliders, and is used to connect to two adjacent shelves simultaneously. With this structure, the first connecting assembly has only one front connecting rod on its front connector for connecting a single shelf, avoiding redundant structure; the second connecting assembly has two front connecting rods on its front connector, allowing simultaneous connection to two adjacent shelves. That is, two adjacent shelves can be connected to the column using a single second connecting assembly, resulting in a compact structure and cost savings.

[0009] Preferably, the front connector also includes a connector extension. The first connecting assembly has only one connector extension on its front connector, while the second connecting assembly has two. Each connector extension has a insertion hole and a insertion rod at both ends. The connector extension also has a threaded hole perpendicular to and communicating with the insertion hole. The front insertion rod is inserted into the insertion hole and locked by a screw screwed into the threaded hole. The insertion rod is inserted into the front connecting hole and locked by a nut. This structure allows for the use of a uniform front connector specification, avoiding increased production costs and reduced production efficiency due to inconsistencies in the specifications of the front connectors of the first and second connecting assemblies.

[0010] Preferably, the pull rod and the front connector are detachably connected. The front connector has a pull rod insertion hole and a connector threaded hole perpendicular to and communicating with the pull rod insertion hole. One end of the pull rod is inserted into the pull rod insertion hole and locked by screwing a screw into the connector threaded hole. This structure facilitates the assembly and disassembly of the pull rod and the front connector.

[0011] Preferably, a column base is provided at both the top and bottom ends of the column, and the column base is used to abut against the floor and ceiling of the space where the column is located. With this structure, only column bases need to be provided at the top and bottom ends of the column, and then the column bases are used to abut against the floor and ceiling of the space where the column is located to fix the column, eliminating the limitation of the installation site of the column, making it convenient to install the expandable shelf of this utility model anytime and anywhere, and easy to disassemble later.

[0012] Preferably, the column base is equipped with a screw rod. One end of the screw rod is threaded to the column base and locked in place by a nut. The other end is inserted into the end of the column, and the length of the screw rod inserted into the column is adjusted by the nut. With this structure, the length of the screw rod inserted into the column can be adjusted by rotating the nut, making the column highly adaptable to the spatial height of the installation site.

[0026] Example 1:

[0027] like Figure 1 As shown, the expandable shelving unit of this utility model includes several spaced-apart uprights 1. Each upright 1 has a support 2 at both its upper and lower ends. The support 2 is used to contact the floor and ceiling of the space where the upright 1 is located. Figure 7 As shown, a screw 2-1 is provided on the column base 2. One end of the screw 2-1 is threaded to the column base 2 and locked in place by a nut 11. The other end is inserted into the end of the column 1 and the length of the screw 2-1 inserted into the column 1 is adjusted by the nut 11.

[0028] Several multi-tiered shelving units 3 are installed between each pair of adjacent columns 1, such as... Figure 2 As shown, the left and right sides of the shelf 3 are provided with a rear connecting hole 3-1 and a front connecting hole 3-2.

[0029] A connecting component 4 is provided between the upright 1 and the shelf 3. The connecting component 4 includes a first connecting component and a second connecting component. The first connecting component is provided on the outermost upright 1 of the expandable shelf of this utility model and is used to connect a single shelf 3. The second connecting component is provided on the inner upright 1 of the expandable shelf of this utility model and is used to connect with two adjacent shelf 3 at the same time.

[0030] like Figure 3 and Figure 4 As shown, the first connecting assembly includes one rear connecting slider 5, one front connecting slider 6, one pull rod 7, and one front connecting head 8. In this embodiment, the cross-section of the column 1 is square, and each of the four sides of the column 1 is provided with a groove 1-1 extending along the length direction; the rear connecting slider 5 is slidably connected to the groove 1-1 located on the left / right side of the column 1, and the rear connecting slider 5 is provided with a rear insertion rod 5-1, which is inserted into the rear connecting hole 3-1 of the shelf 3 and locked by a nut 11; the front connecting slider 6 is slidably connected to the groove 1-1 located on the front side of the column 1, and the front connecting head 8 is slidably connected to the groove 1-1 located on the front side of the column 1. A rotating head seat 6-1 is provided on the connecting slider 6. One end of the pull rod 7 is provided with a connector 7-1, which is spherical and rotatably connected to the rotating head seat 6-1. The front connector 8 is provided with a pull rod insertion hole 8-1 and a connector threaded hole 8-2 perpendicular to and communicating with the pull rod insertion hole 8-1. The other end of the pull rod 7 is inserted into the pull rod insertion hole 8-1 and locked by screwing screw 10 into the connector threaded hole 8-2. A front insertion rod 8-3 is provided on the front connector 8, which is inserted into the front connection hole 3-2 of the shelf 3 and locked by nut 11. The position of the front connecting slider 6 on the column 1 is higher than the position of the shelf 3 on the column 1. The length of the pull rod 7 is greater than the width of the shelf 3. The pull rod 7 is obliquely connected between the front connecting slider 6 and the front connector 8.

[0031] In this embodiment, the front connector 8 of the first connecting component is further provided with a connector extension 9. The connector extension 9 has a insertion hole 9-1 and an insertion rod 9-2 at both ends. The connector extension 9 also has an extension threaded hole 9-3 that is perpendicular to and communicates with the insertion hole 9-1. The front insertion rod 8-3 is inserted into the insertion hole 9-1 and locked by screwing a screw 10 into the extension threaded hole 9-3. The insertion rod 9-2 is inserted into the front connecting hole 3-2 and locked by a nut 11. The front connector 8 and the connector extension 9 can be considered as a single unit. Thus, the insertion rod 9-2 of the connector extension 9 can be considered as the front insertion rod 8-3 of the front connector 8, achieving the aforementioned insertion of the front insertion rod 8-3 into the front connecting hole 3-2 of the shelf 3.

[0032] like Figure 5 and Figure 6As shown, the second connecting component is located between two adjacent shelf panels 3. The difference between the second connecting component and the first connecting component is that there are two rear connecting sliders 5 and two front insertion rods 8-3 are provided on the front connecting head 8. Each front insertion rod 8-3 is provided with a connecting head extension 9. Other connection methods are the same as the first connecting component, so it can be connected to two adjacent shelf panels 3 at the same time.

[0033] Example 2:

[0034] The difference between the expandable shelf in this embodiment and that in Embodiment 1 lies in the structure of the front connector 8 in the connecting assembly. For example... Figure 8 As shown, the length of the front connector 8 of the first connecting component in this embodiment is greater than that of the front connector 8 in embodiment 1. In this embodiment, the front connector 8 of the first connecting component no longer has a connector extension 9; instead, the front insertion rod 8-3 is directly inserted into the front connecting hole 3-2 of the shelf 3. For example... Figure 9 As shown, the length of the front connector 8 of the second connecting component in this embodiment is also greater than that of the front connector 8 in embodiment 1. Furthermore, the front connector 8 of the second connecting component in this embodiment no longer has two connector extensions 9; instead, the front insertion rods 8-3 are directly inserted into the front connecting holes 3-2 of the left and right storage plates 3. In other words, the front connector 8 of the first connecting component in this embodiment is a one-piece structure combining the front connector 8 and connector extensions 9 of embodiment 1, while the front connector 8 of the second connecting component in this embodiment is a one-piece structure combining the front connector 8 of embodiment 1 and the two left and right connector extensions 9.

[0035] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
