BACKGROUND OF THE INVENTION

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

A shelf is a type of furniture commonly used in the home to hold kitchen items, books, various decorations, and other items. Existing common shelves on the market generally include support rods, support frames and storage boards. The support frames are fixed to the support rods, and then each storage board is fixed between every two support frames, thereby forming a shelf.

However, in order to improve the flexibility and portability of the shelves, manufacturers generally set the connection between upright columns and the support frames, and between the support frames and the storage boards as a detachable connection, which is convenient for transportation, and these components are taken out and assembled on site for use. Since it is needed to assemble the shelves on site, ease of assembling and stability after assembling are issues that designers need to consider. At present, some shelves on the market do not have ideal connection and stability between the various components.

Therefore, providing a shelf that is easy to assemble, stable and not easy to shake is a technical problem that the designer must consider.

SUMMARY OF THE INVENTION

The present invention provides a shelf, aiming at solving the technical problem that connecting structures between support rods and support frames of the shelf in related technology are not stable enough.

The present invention provides a shelf, including:

• • support rods of which the back surfaces are provided with at one neck; and
  • support frames which are used for mounting storage boards, each support frame including a horizontal portion and a vertical portion which are fixedly interconnected, in which, the vertical portion is bent backwards from one end of the horizontal portion to form a vertical accommodating groove. The accommodating grooves partially surround the support rods and are provided with at least one clamping portion at a position facing the necks in the back surfaces of corresponding support rods; and the clamping portions are inserted into the necks and abut against the inner walls of the support rods.

Further, a plurality of necks spaced by the same distance are formed in the back surfaces of the support rods in the length direction; and a plurality of clamping portions matched with the necks are arranged on the parts, extending to the back surfaces of the support rods, of the support frames.

In one embodiment, the clamping portions are inserting pieces bent inwards from the side surfaces of the accommodating grooves, and the inserting pieces can be obliquely inserted into the necks and abut against the inner walls of the support rods.

In another embodiment, the clamping portions are hooks formed by bending inwards from the side surfaces of the accommodating grooves and then bending downwards, and the hooks can be obliquely inserted into the necks and abut against the inner walls of the support rods.

Preferably, two clamping portions can be inserted into the necks side by side.

Further, when assembling the shelf, adjacent storage boards share one support rod, the accommodating grooves in adjacent support frames surround the support rod from the left side and right side respectively, and the clamping portions on the adjacent support frames are inserted into the same neck.

In one embodiment, the support rods are rectangular hollow pipes, and the necks are rectangular grooves.

Further, a fixing rod is arranged at the bottom between every two support rods.

Further, a base support is arranged at the bottom of each support rod.

In one embodiment, telescopic ejector rods and adjusting screws are arranged at the top ends of the support rods and used for fixing the shelf between the ground and a ceiling.

Compared with the prior art, the present invention has the following advantages:

• • the clamping portions of the support frames are obliquely inserted into the corresponding necks in the support rods, then the support frames are placed upright, thus the clamping portions can tightly abut against the inner walls of the support rods below the necks through the gravity of the support frames, and then it is guaranteed that the support rods and the support frames are stably connected and cannot shake.

DETAILED DESCRIPTION OF SOME EMBODIMENTS

The principle and structure of the present invention are described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment 1

With reference to FIG. 1 to FIG. 3, the present invention provides a shelf; and connecting structures between support rods and support frames of the shelf are stable and not prone to shaking. The shelf includes: support rods 10, support frames 20 and storage boards 30. Every two support frames 20 support one storage board 30. A plurality of necks 101 are formed in the back surfaces of the support rods 10. Each support frame 20 includes a horizontal portion 203 and a vertical portion 204 which are fixedly interconnected. Each vertical portion is bent backwards from one end of the corresponding horizontal portion to form a vertical accommodating groove 202 with a leftward or rightward opening; the accommodating grooves partially surround the support rods 10 and are provided with at least one clamping portion 201 at the position facing the necks 101 in the back surfaces of the support rods; and the clamping portions are inserted into the necks 101 and abut against the inner walls of the support rods.

In an Embodiment 1, the clamping portions 201 are inserting pieces which are punched inwards and bent from the side walls of the accommodating grooves 202 corresponding to the necks 101, and the inserting pieces can be obliquely inserted into the necks 101 and abut against the inner walls of the support rods below the necks 101.

As shown in FIG. 6, when mounting the support frames 20 on the support rods 10, the support frames are inclined to obliquely insert the clamping portions 201 inserted into the corresponding necks 101, then the support frames 20 are placed right, thus the clamping portions 201 can tightly abut against the inner walls of the support rods in the lower portions of the necks 101 through the gravity of the support frames, and meanwhile, the inner side walls of the accommodating grooves 202 can be tightly attached to the corresponding side walls of the support rods 10, and therefore it is guaranteed that the connecting structures between the support rods and the support frames are stable and not prone to shaking.

The clamping portions are obliquely inserted into the corresponding necks, so that the operation of mounting the support frames on the support rods is very convenient and labor-saving; and the clamping positions of the clamping portions and the necks are all on the back surfaces of the support rods, which improve the attractiveness of the shelf.

With reference to FIG. 1, a plurality of necks 101 spaced by the same distance are vertically formed in the back surfaces of the support rods 10 in the length direction, and can be used for adjusting the placement height of the storage boards or placing a plurality of layers of storage boards.

It is to be noted that a group of necks 101 with different heights can be arranged for each storage board 30, thus the position of the storage board can be conveniently adjusted. Because the flexibility of connection between the support rods 10 and the support frames 20 is improved, the use experience of a user can be increased.

In order to further improve the stability of the connecting structures between the support rods 10 and the support frames 20, with reference to FIG. 1, for one support frame 20, a part extending from one end to the back surface of the corresponding support rod 10 can also be provided with two clamping portions 201.

In the present invention, according to the actual requirements, the part extending from one end of each support frame 20 to the back surface of the corresponding support rod 10 is vertically provided with three or more clamping portions 201, which is not limited herein.

In order to improve the convenience of inserting the clamping portions 201 into the corresponding necks 101, with reference to FIG. 1, the bottom ends of the clamping portions 201 are arc-shaped.

When mounting, a part of each support rod 10 is placed in the corresponding accommodating groove 202. The outward side walls of the accommodating grooves are provided with at least one inwards-bent inserting piece, and the inserting pieces are used as the clamping portions 201 to be matched with the necks 101 so as to connect the support frames 20 to the corresponding support rods 10.

In order to facilitate clamping of the clamping portions 201 and the necks 101, the support rods 10 are preferably rectangular hollow rods, and the necks 101 in the support rods 10 are square grooves. If circular hollow rods are used, the necks 101 and connecting members 201 can be made into corresponding arc-shaped structures.

FIG. 4 is a schematic diagram of a mounting mode of a shelf. In the schematic diagram, the shelf includes two support rods 10, two storage boards 30, and four support frames 20; and one storage board 30 is fixed to the tops of the two support frames 20 at the same horizontal position on the two support rods 10.

The storage boards 30 can provide an article placement platform, and the two support frames 20 can also achieve a firm supporting effect. The connection relationship between the support frames 20 and the storage boards 30 includes but is not limited to bolt connection or clamping connection. The storage boards 30 can further make the clamping portions 201 tightly abut against the inner walls of the support rods 10 on the lower portions of necks 101 according to the weight of the storage boards 30 and in combination with the weight of the corresponding support frames 20, thereby further enhancing the stability of the connection structures between the support rods 10 and the support frames 20.

In order to ensure the stability of the shelf, a fixing rod 40 is horizontally connected to the bottom between the two support rods 10, as shown in FIG. 4.

The materials of the support rods and the support frames can be any one of carbon steel, stainless steel and aluminum alloy.

It is to be noted that in this embodiment, the materials for manufacturing the support rods and the support frames are preferably carbon steel, thus the manufactured shelf has good the bearing performance and can bear large loads and pressure, and is not prone to deformation or damage in the using process; the shelf has good abrasion resistance, keeps good performance in long-time use, and has long service life; and the carbon steel is relatively low in cost, has high cost performance, and is suitable for large-scale production and application.

The support rods 10 are preferably square pipes of hollow structures, therefore, the weight of the support rods 10 can be reduced, the used materials for the shelf are reduced, and the cost of the shelf is reduced.

In this embodiment, the shelf is mounted by the following steps:

• • arranging the two support rods 10 side by side, then sequentially inclining the clamping portions 201 of a plurality of support frames 20 and inserting into the corresponding necks 101, then placing upright the support frames 20 to make the clamping portions 201 tightly abut against the inner walls of the support rods in the lower portions of the necks 101 through the gravity, and meanwhile to make the inner side walls of accommodating grooves 202 tightly attach to the corresponding side walls of the support rods 10.

It is to be ensured that the support frames 20 on the two support rods 10 are at the same horizontal position, and then the storage boards 30 are mounted on the two support frames 20 at the same horizontal position.

According to the present invention, the shelf can be assembled to lengthen the storage space. As shown in FIG. 5, the assembled shelf includes three support rods 10, six support frames 20 and three storage boards 30. When splicing the shelf, adjacent storage boards 30 share one support rod 10, and meanwhile, one support frame in which the corresponding accommodating groove 202 is leftwards opened and one support frame in which the corresponding accommodating groove 202 is rightwards opened are selected, as shown in FIG. 7, FIG. 8 and FIG. 9. The clamping portions 201 on the adjacent support frames 20 are inserted into the same neck 101 in the corresponding support rod.

Specifically, two transversely-arranged clamping portions 201 are inserted into one neck 101 in the support rod 10 in the middle, that is, two support frames 20 are mounted on the support rod 10 in the middle. One clamping portion 201 is inserted into each of the necks 101 at the same horizontal position in support rods 10 on two sides, that is, each of the support rods on the two sides is equipped with one support frame 20. Then, one storage board 30 is mounted between the support frame 20 on the support rod in the middle and the support frame 20 on the corresponding support rods on the two sides, and thus the splicing mounting of the shelf is completed. FIG. 9 is a schematic diagram of adjacent storage boards sharing one support rod in splicing of a shelf.

In order to guarantee the modular design of the shelf, the size of the shelf can be flexibly expanded according to actual needs, and two transversely-arranged clamping portions 201 can be matched and inserted into each neck 101.

In this embodiment, a fixing rod 40 is horizontally connected between the bottoms of any two adjacent support rods 10, and therefore the shelf is more stable.

Embodiment 2

As shown in FIG. 6, the shelf in the Embodiment 2 of the present invention includes: support rods 10, support frames 20 and storage boards 30. The Embodiment 2 is different from the Embodiment 1 in that the clamping portions 201 are not the structure of inserting pieces but hooks. Specifically, each vertical portion 204 is bent backwards from one end of the corresponding horizontal portion 203 to form a vertical accommodating groove 202, the accommodating groove 202 partially surrounds the corresponding support rod 10, the end of the side edge of the accommodating groove 202 is bent inwards to form a hook at the position facing the corresponding neck 101 in the back surface of the corresponding support rod 10, and the hook can be inserted into the corresponding neck 101 and abuts against the inner wall of the corresponding support rod 10.

Except the clamping portions 201, the structures and mounting modes of the support rods 10, the support frames 20 and the storage boards 30 in the Embodiment 2 are the same as those in the Embodiment 1 and are not listed herein.

As shown in FIG. 10, telescopic ejector rods 60 and adjusting screws 70 can be arranged at the top ends of the support rods and used for fixing the shelf between the ground and a ceiling.

Obviously, the embodiments described above are only partial embodiments of the present invention, not all embodiments. It is to be understood that, for those skilled in the art, changes may be made to the technical solutions recorded in the aforesaid specific embodiments, or to replace some of the technical features equivalently, and these changes and substitutions shall be covered by the scope of protection of the claims of the present invention.
