Description

Technical Field

[0001] The utility model relates to the technical field of household articles, in particular to a rotating connection structure and a storage rack having the structure. Background Art

[0002] A shelf is a place to store miscellaneous items. In the kitchen or bathroom, people often need to install shelves on the wall to store seasonings or toiletries. Depending on the installation location, shelves can be divided into rectangular shelves installed on the wall and fan-shaped shelves or triangular shelves installed in the corner. Traditional shelves are mostly fixed structures that cannot be adjusted and have poor adaptability. Rectangular shelves cannot be installed in the corner of the wall. Fan-shaped shelves or triangular shelves have fixed sizes and angles, making it difficult for consumers to purchase shelves with the right angle and size for their actual needs. Usually, they need to be customized.

[0003] Currently, there are also racks on the market that can be rotated and adjusted to fit corners. These racks have two rotating mating bases, and the angle between the two bases can be adjusted accordingly to achieve corner installation. CN213664272U discloses a rack whose rotating portion uses elastic retaining walls to achieve engagement. The elastic retaining walls are subjected to force at the lower end surface, resulting in poor rotational stability. The elastic retaining walls are easily unhooked, causing the components to separate. Furthermore, the connection part is a double-layer structure with a distinct interface, which makes it aesthetically pleasing. Utility Model Content

DETAILED DESCRIPTION

[0052] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0053] A shelf is a place to store miscellaneous items. In kitchens and bathrooms, people often install shelfs on the wall to store condiments and toiletries. CN213664272U discloses a shelf whose rotating portion relies on an elastic retaining wall for engagement. The elastic retaining wall bears force at the lower end, resulting in poor rotational stability and the retaining wall being easily disengaged, causing the components to separate. Furthermore, the connection is a double-layer structure with a distinct interface, resulting in poor aesthetics.

[0054] Example 1

[0055] In response to the above problems, Example 1 provides a rotating connection knot with good rotation structure stability and more beautiful appearance, which is suitable for a storage rack.

[0056] like Figure 1-3 As shown, a rotating connection structure:

[0057] It includes an inner set 100, an outer set 200, a supporting portion 300 and a trustee portion 400;

[0058] The outer kit 200 is mounted on the inner kit 100;

[0059] One of the supporting portion 300 and the entrusted portion 400 is provided on the inner sleeve 100 , and the other is provided on the outer sleeve 200 ;

[0060] The supporting portion 300 can support the receiving portion 400 to form a revolving pair;

[0061] When in use, the supporting portion 300 and the receiving portion 400 cooperate to realize relative rotation of the two components, and the angle can be adjusted according to the actual installation position. When used as a shelf, the shelf can be adapted to be installed in corners of walls at different angles.

[0062] The outer sleeve 200 is sleeved on the inner sleeve 100, so that the rotating structure is shielded by the outer sleeve 200 and the rotating structure does not leak out. The sleeve-shielded design does not form an obvious rotating interface in the overall visual effect when viewed from the outside, thereby improving the aesthetics.

[0063] The rotating part is located between the outer kit 200 and the inner kit 100, and the rotating force-bearing part is located inside rather than on the lower end surface. The overall structural strength is better, and the supporting part 300 has both supporting and limiting functions, and the rotating structure is more stable.

[0064] In this embodiment, the rotation connection structure further includes a limiting portion 500, which is provided on the inner sleeve 100. The entrusted portion 400 is located between the supporting portion 300 and the limiting portion 500, and the entrusted portion 400 rests on the supporting portion 300.

[0065] The supporting part 300 and the limiting part 500 cooperate together to limit the trusted part 400 axially in the inner sleeve 100, so that the supporting part 300 and the trusted part 400 are not easy to loosen, and a tight combination between the supporting part 300 and the limiting part 500 is achieved, making it difficult to disassemble and having better rotation stability.

[0066] Preferably, the limiting portion 500 is used to limit the top surface or bottom surface of the outer sleeve. When the supporting portion 300 is arranged on the inner sleeve 100, the limiting portion 500 is arranged on the top surface of the inner sleeve 100 to limit the top surface of the outer sleeve 200 to prevent the outer sleeve 200 from falling off upward; when the supporting portion 300 is arranged on the outer sleeve 200, the limiting portion 500 is arranged on the bottom surface of the inner sleeve 100 to limit the bottom surface of the outer sleeve 200 to prevent the outer sleeve 200 from falling off downward.

[0067] Example 2

[0068] Based on Example 1, Example 2 further designs the specific matching structure of the supporting portion 300 and the entrusted portion 400 of the hook portion 120.

[0069] like Figure 4 As shown, the features of embodiment 2 are basically the same as those of embodiment 1, except that the outer wall of the inner sleeve 100 and the inner wall of the outer sleeve 200 are both provided with a step surface 410;

[0070] The step surfaces 410 on the inner and outer kits 100 and 200 are set in opposite directions. The reverse setting here specifically refers to the two step surfaces 410 facing in opposite directions in the rotation axis, so as to facilitate the overlap of the two after assembly, wherein one step surface 410 serves as a supporting part and the other step surface 410 serves as a trusted part.

[0071] In practical applications, in order to facilitate the assembly of the two step surfaces 410 on the inner and outer sleeves 100 and 200 , the outer wall of the inner sleeve 100 and / or the inner wall of the outer sleeve 200 are tapered.

[0072] Example 3

[0073] Based on Example 1, Example 3 further designs the specific matching structure of the supporting portion 300 and the entrusted portion 400 of the hook portion 120.

[0074] like Figure 1-3 , 5-6, the features of embodiment 3 are basically the same as those of embodiment 1, except that:

[0075] The supporting portion 300 and the receiving portion 400 are both ribs, also known as reinforcing ribs, which play a role in connecting and strengthening the strength of the plastic product.

[0076] Alternatively, the supporting portion 300 is the annular groove 310 , and the entrusted portion 400 is a bone position.

[0077] In this embodiment, the bone position is an annular rib 210;

[0078] Alternatively, the bone position is formed by a plurality of arc-shaped convex ribs 110 evenly distributed around the circumference of the central axis of the inner sleeve 100.

[0079] In this embodiment, when the supporting portion 300 and the receiving portion 400 both adopt the arc-shaped convex rib 110 structure, gaps 120 are formed between adjacent arc-shaped convex ribs 110 of the supporting portion 300;

[0080] The arc length of the gap 120 is smaller than the arc length of the arc-shaped rib 110 of the trusting part 400. This design prevents the arc-shaped rib 110 of the trusting part 400 from passing through the gap 120, thereby ensuring that the supporting part 300 can stably support and limit the trusting part 400.

[0081] In this embodiment, at least one supporting portion 300 is provided axially spaced apart along the inner sleeve 100, and the receiving portion 400 corresponds to each supporting portion 300. Preferably, one supporting portion 300 is provided, and the supporting portion 300 is centrally located. Specifically, the supporting portion 300 is provided in the middle of the outer wall of the inner sleeve 100 or the middle of the inner wall of the outer sleeve 200. This central location improves the stability of the rotating structure, while also ensuring that the rotating structure does not leak, thereby enhancing the aesthetics.

[0082] Example 4

[0083] Example 4 is based on Example 1, Example 2 or Example 3, and specifically applies the rotating connection structure to the shelf, so that the shelf can adjust the angle to adapt to the installation on the wall or the corner at the same time.

[0093] In this embodiment, top wall posts 820 are provided on the back of each of the first basket body 700 and the second basket body 800. Specifically, the top wall posts 820 are provided at the lower portion of the back of each of the first basket body 700 and the second basket body 800, and are provided on both sides of the vertical slots 810. The top wall posts 820 are used to support the wall after the shelf is installed, thereby improving installation stability.

[0094] In this embodiment, when the supporting portion 300 is disposed on the inner sleeve 100 , a limiting portion 500 is disposed on the top surface of the inner sleeve 100 ;

[0095] When the supporting portion 300 is disposed on the outer sleeve 200 , a limiting portion 500 is disposed on the bottom surface of the inner sleeve 100 ;

[0096] The first basket 700 is connected to the inner sleeve 100 via the limiting portion 500;

[0097] The top surface or the bottom surface of the second basket 800 is correspondingly provided with a recess for evading the limiting portion 500;

[0098] The recessed portion is used to ensure that the upper and lower end surfaces of the first basket 700, the second basket 800, and the inner housing 100 are flush after the rack is assembled, thereby improving the aesthetics. Preferably, the first basket 700, the second basket 800, and the inner housing 100 are of the same height. After the rack is assembled, the top surface of the stopper 500 is flush with the top surface of the recessed portion. One end of the outer housing 200 abuts against the stopper 500 on one end surface of the inner housing 100, while the other end is flush with the other end surface of the inner housing 100.

[0099] In this embodiment, at least the second basket 800 is eccentrically disposed relative to the inner sleeve 100;

[0100] The back of the second basket 800 is tangent to the outer sleeve 200, and the front of the second basket 800 is located between the central axis of the inner sleeve 100 and the outer wall of the outer sleeve 200;

[0101] When the first basket 700 and the second basket 800 are parallel (i.e., the angle between the first basket 700 and the second basket 800 is zero), the back surface of the first basket 700 and the back surface of the second basket 800 are coplanar;

[0102] Preferably, to enhance the overall aesthetics, the first basket body 700 and the second basket body 800 have the same dimensions, and the first basket body 700 is also eccentrically disposed relative to the inner sleeve 100. When the first basket body 700 and the second basket body 800 are parallel, the front surface of the first basket body 700 is also coplanar with the front surface of the second basket body 800.

[0103] Example 5

[0104] Example 5 is based on Example 4, and further expands the function design of the storage rack.

[0105] like Figure 6-8 As shown, the features of Example 5 are basically the same as those of Example 4, except that:
