Description

Technical Field

[0001] This utility model relates to the field of shelving, and more specifically, to a household shelving unit with easily removable crossbeams. Background Technology

[0002] Household shelves are used to store items, improve space utilization, and keep the home tidy. Household shelves are usually composed of three main parts: a support frame, shelves (or wire mesh), and connectors. The support frame includes uprights and beams. Uprights and beams are usually connected and fixed with bolts. Shelves are laid on the beams for placing items.

[0003] The utility model patent with application number 202222686266.9 discloses a beam-type shelf that is easy to disassemble. Through support columns, counterweights, beams and quick disassembly and installation components, the beams can be easily and quickly disassembled or positioned for installation. Moreover, the structure is simple, requires very little material, reduces cost expenditure, can accommodate more beams at the same time, and the more beams there are, the more stable the whole structure becomes, thus improving the overall practicality.

[0004] According to the above technical solution, the crossbeam is a rod-shaped structure. In use, two crossbeams need to be set parallel and horizontally, and the two ends of the shelf are then installed and fixed on the two crossbeams to make the shelf horizontal for placing items. However, there is no structure between the two crossbeams to support the shelf, which makes the shelf installed on the crossbeam prone to deformation when bearing weight. Although the existing technology designs the crossbeam as a ladder to support the shelf and prevent it from deforming or collapsing under load, the assembly of the crossbeam using bolts is time-consuming and laborious. When the crossbeam needs to be disassembled for packaging and transportation, the disassembly operation is also cumbersome and time-consuming. If the crossbeam of this structure is fixed, the overall volume of the crossbeam is too large, which wastes packaging materials and makes transportation inconvenient, increasing packaging costs. While it cannot guarantee the supporting effect of the crossbeams on the shelves to prevent deformation and collapse under load, the crossbeams are assembled using a boltless structure, which allows for quick assembly, saving time and effort. Furthermore, when it is necessary to reduce the volume of the crossbeams to save packaging materials, the crossbeams can be quickly disassembled, facilitating packaging and transportation and reducing packaging costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a household shelf with a removable crossbeam.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A household shelving unit with easily detachable crossbeams includes a support frame and shelves. The support frame includes uprights and crossbeams. Shelves are laid on the crossbeams. There are four uprights. Each crossbeam includes two parallel crossbars and several support rods placed between the two crossbars. The two ends of the two crossbars are detachably connected to the four uprights. The several support rods are evenly distributed along the length of the crossbars. The crossbars have a C-shaped cross-section. The openings of the two crossbars are positioned opposite each other. The two ends of the support rods extend into the C-shaped spaces of the two crossbars. The crossbars have snap-fit ​​holes that correspond one-to-one with the several support rods. Two snap-fit ​​blocks corresponding to the two crossbars are fixed on the support rods. The snap-fit ​​blocks engage with the snap-fit ​​holes on the corresponding crossbars.

[0008] Further configured, the column is C-shaped, and includes a plurality of reserved holes evenly arranged along the height direction of the column. The reserved holes are in the shape of right trapezoids. Mounting plates are fixed at both ends of the crossbar. The mounting plates are L-shaped, and hook blocks that cooperate with the reserved holes are fixed on the mounting plates. The hook blocks are movably connected to the upper part of the reserved holes and engaged with the lower part of the reserved holes. The length of the hook blocks is less than the diameter of the upper part of the reserved holes and greater than the diameter of the lower part of the reserved holes.

[0009] Further configured, the support rod includes two opposing support surfaces, one support surface contacts the bottom of the shelf, and the other support surface contacts the inner wall of the crossbar, and the support rod includes two grooves that respectively engage with the two crossbars.

[0010] A further configuration is provided, wherein a positioning hole corresponding to the shelf is opened on one of the support surfaces, and a positioning protrusion that is inserted into the positioning hole is fixed on the shelf.

[0011] Further configured, each of the two sides of the column is provided with a plurality of gourd holes evenly arranged along the height direction of the column, the plurality of gourd holes corresponding one to one with a plurality of reserved holes, the mounting plate is provided with a connecting block that mates with the gourd holes, the connecting block is inserted into the upper part of the gourd hole, the connecting block is snapped into the lower part of the gourd hole, the cross-section of the connecting block is T-shaped, and the diameter of one end of the connecting block is larger than the lower hole diameter of the gourd hole.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: it can ensure the supporting role of the crossbeam on the shelf and prevent the shelf from deforming or collapsing when bearing weight, while the crossbeam can be assembled in a boltless structure, which can quickly assemble the crossbeam, saving time and effort. In order to save packaging materials and reduce the volume of the crossbeam, the crossbeam can be quickly disassembled for easy packing and transportation, reducing packaging costs.

Detailed Implementation

[0019] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0020] A household shelving unit with easily detachable crossbeams includes a support frame 100 and shelves 200. The support frame 100 includes uprights 101 and crossbeams 102. The shelves 200 are laid on the crossbeams 102. There are four uprights 101. The crossbeams 102 include two parallel crossbars 1 and several support rods 2 placed between the two crossbars 1. The two ends of the two crossbars 1 are detachably connected to the four uprights 101 respectively. The several support rods 2 are evenly distributed along the length of the crossbars 1. The crossbars 1 have a C-shaped cross section. The opening of the two crossbars 1... The support rods 2 are arranged opposite each other at the opening, with both ends extending into the C-shaped spaces of the two crossbars 1. The crossbars 1 have snap-fit ​​holes 3 that correspond one-to-one with the support rods 2. The support rods 2 are fixed with two snap-fit ​​blocks 4 that correspond to the two crossbars 1 respectively. The snap-fit ​​blocks 4 snap into the snap-fit ​​holes 3 on the corresponding crossbars 1. The support rods 2 include two oppositely arranged support surfaces 21. One support surface 21 contacts the bottom of the shelf 200, and the other support surface 21 contacts the inner wall of the crossbars 1. The support rods 2 include two grooves 22 that snap into the two crossbars 1 respectively.

[0021] Working principle: The two ends of the support rod 2 extend into the C-shaped spaces of the two crossbars 1 respectively. The crossbars 1 and support rods 2 are quickly fixed by engaging the locking blocks 4 on the support rods 2 with the locking holes 3 on the crossbars 1. This allows the assembly of the crossbeam 102 to be completed without tools; simply insert several support rods 2 one by one into the C-shaped spaces of the crossbars 1 and engage the locking blocks 4 with the locking holes 3. This boltless assembly of the crossbeam 102 is convenient, time-saving, and labor-saving, improving assembly efficiency. Simultaneously, the support rods 2 are evenly distributed along the length of the crossbars 1. The two support surfaces 21 of the support rods 2 contact the bottom of the shelf 200 and the inner wall of the crossbars 1 respectively, ensuring that the crossbeam 102 evenly distributes the weight of the shelf 200 during use. This ensures stable support of the shelf 200 by the crossbeam 102 and prevents deformation or collapse of the shelf 200 under load.

[0022] When it is necessary to disassemble the crossbeam 102 in order to save packaging materials, simply lift the support rod 2 to disengage the clip 4 from the snap-fit ​​hole 3, and then tilt the support rod 2 to facilitate its removal from the C-shaped space of the crossbar 1. This allows the support rod 2 and the crossbar 1 to be easily separated, disassembling the crossbeam 102 into independent components, reducing the volume of the crossbeam 102, facilitating packaging and transportation, and thus reducing packaging costs.

[0023] The column 101 is C-shaped and includes several reserved holes 5 evenly arranged along the height direction of the column 101. The reserved holes 5 are in the shape of right trapezoids. The two ends of the crossbar 1 are fixed with mounting plates 6. The mounting plates 6 are L-shaped and have hooks 7 that cooperate with the reserved holes 5. The hooks 7 are movably connected to the upper part of the reserved holes 5 and are engaged with the lower part of the reserved holes 5. The length of the hooks 7 is less than the diameter of the upper part of the reserved holes 5 and greater than the diameter of the lower part of the reserved holes 5.

[0024] The snap-fit ​​structure between the pre-drilled hole 5 and the hook block 7 enables the disassembly and connection of the crossbar 1 and the column 101. By inserting the hook block 7 into the pre-drilled hole 5 from the upper part of the larger diameter hole, and then pressing the crossbar 1 downwards to snap the hook block 7 into the lower part of the pre-drilled hole 5 with the smaller diameter hole, the crossbar 1 can be fixed to the column 101 without bolts. The boltless connection between the crossbar 1 and the column 101 simplifies the assembly and disassembly process of the crossbar 1 and the column 101, making the assembly and disassembly of the crossbar 1 and the column 101 more convenient, greatly reducing assembly time and labor intensity, and improving the operational flexibility of the crossbeam 102 during assembly and disassembly.

[0025] The length of the hook block 7 is greater than the diameter of the lower part of the reserved hole 5, so that the hook block 7 will not detach from the reserved hole 5 when there is no external force interference, preventing the crossbar 1 from loosening on the upright 101, ensuring the connection stability between the crossbar 1 and the upright 101, and improving the overall stability of the shelf.

[0026] The pre-drilled holes 5 are evenly arranged along the height of the uprights 101. Users can adjust the installation height of the crossbars 1 as needed, thereby changing the shelf height to meet different usage requirements and improve the versatility and practicality of the shelf.

[0027] A positioning hole 23 corresponding to the shelf 200 is opened on a support surface 21, and a positioning protrusion 8 that is inserted into the positioning hole 23 is fixed on the shelf 200.

[0028] The insertion and engagement of the positioning hole 23 and the positioning protrusion 8 ensures that the shelf 200 can be quickly and accurately installed on the beam 102, improving the efficiency and quality of shelf assembly. At the same time, the insertion structure of the positioning protrusion 8 and the positioning hole 23 can effectively prevent the shelf 200 from shaking or shifting on the beam 102, which helps to improve the support stability of the beam 102 on the shelf 200. When the shelf 200 is under load, the beam 102 can best distribute the weight of the shelf 200, and better prevent the shelf 200 from deforming or collapsing.

[0029] On both sides of the column 101, there are several gourd-shaped holes 9 evenly arranged along the height direction of the column 101. The gourd-shaped holes 9 correspond one-to-one with several reserved holes 5. The mounting plate 6 is provided with connecting blocks 10 that cooperate with the gourd-shaped holes 9. The connecting blocks 10 are inserted into the upper part of the gourd-shaped holes 9 and snapped into the lower part of the gourd-shaped holes 9. The cross-section of the connecting blocks 10 is T-shaped, and the diameter of one end of the connecting blocks 10 is larger than the lower diameter of the gourd-shaped hole 9 and smaller than the upper diameter of the gourd-shaped hole 9.

[0030] When the hook block 7 extends into the pre-drilled hole 5 from the top, the connecting block 10 extends into the hoist hole 9 from the top. When the crossbar 1 is pressed down to make the hook block 7 engage with the lower part of the pre-drilled hole 5, the connecting block 10 engages with the lower part of the hoist hole 9. Through the engaging structure of the hoist hole 9 and the connecting block 10, an additional fixing point is provided between the crossbar 1 and the upright 101, further enhancing the connection strength between the crossbar 1 and the upright 101, ensuring the structural stability of the support frame 100, improving the load-bearing capacity of the support frame 100, and preventing deformation or collapse of the shelf during use. At the same time, it does not increase the operation steps of fixing the crossbeam 102 and the upright 101. The cross-section of the connecting block 10 is T-shaped, and the diameter of one end of the connecting block 10 is larger than the lower diameter of the hoist hole 9, preventing the connecting block 10 from accidentally detaching from the hoist hole 9 when there is no external force, thus affecting the connection stability between the crossbeam 102 and the upright 101.
