DETAILED DESCRIPTION

[0043] The present subject matter pertains to improved approaches for a screw-free and highly stable coupling structure between adjacent boards. Embodiments of the present subject matter are discussed below with reference to FIGS. 1-19.

[0044] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present subject matter. It will be apparent, however, to one skilled in the art that the present subject matter may be practiced without some of these specific details. In addition, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. Moreover, these examples should not be construed in a limiting sense as they are merely intended to provide examples of embodiments of the subject matter rather than to provide an exhaustive list of all possible implementations. In other instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the details of the disclosed features of various described embodiments.

Embodiment I

[0045] As shown in FIGS. 1 to 5, the board coupling structure of this embodiment can comprise a first board 1 and a second board 2 that can be inserted and interlocked into each other. The first board 1 and the second board 2 can be rectangle or square boards. When they are coupled, the first board 1 and the second board 2 can be perpendicular to each other. According to some embodiments, the first board 1 and the second board 2 can be respectively formed with at least one strip-shaped rib 11 and at least one strip-shaped groove 21 that can be inserted or plug-in into each other, so that the first board 1 and the second board 2 can only move in the insertion direction.

[0046] The strip-shaped rib 11 of this embodiment can be disposed on one of the circumferential side surfaces 12 of the first board 1, whereas the strip-shaped groove 21 can be disposed on the inner side wall of the second board 2 and near an edge of the second board 2 along the length direction of the edge. According to some embodiments, the shape of the strip-shaped groove 21 can be adapted to the strip rib 11, with one end of the strip groove 21 forming an opening, and the other end being closed. As such, it can facilitate the insertion of the first board 1 and the second board 2 to form the coupling structure.

[0047] According to some embodiments, the circumferential side 12 of the first board 1 can extend outwardly to form a longitudinally extending arm 111 that is perpendicular to the circumferential side 12. In this embodiment, an inclined arm 112 can obliquely extend from the two sides of the longitudinally extending arm 111, which can jointly form the stripe-shaped rib 11. According to some embodiments, the inclined arm 112 is X-shaped, and the outer end of the longitudinally extending arm 111 meets the center of the X-shaped inclined arm 112. With the X-shaped shaped cross-section, the contact area between the strip-shaped rib 11 and the stripe-shaped groove 12 is larger. On the one hand, the board coupling structure can improve the bite and make the structure more stable and reliable. On the other hand, it can also facilitate the waterproofing of the connection between the two boards.

[0048] In this embodiment, the first board 1 can be the bottom board of the cabinet, and the second board 2 can be the side board of the cabinet. When interlocking with each other, the first board 1 can be horizontally placed, and then the second board 2 can be placed in a vertical position. A user can backwardly insert the stripe-shaped rib 11 from the open end of the stripe-shaped groove 21 until the rear end of the stripe-shaped rib 11 and the closed end of the stripe-shaped groove 21 abut, thereby completing the coupling of the first board 1 and the second board 2.

[0049] According to some embodiments, the board coupling structure can also be applied to the connection or joint between other adjacent boards of the cabinet. For example, the first board 1 can be the right side board of the cabinet and the second board 2 can be the front side board of the cabinet, which can be interlocked with each other. By eliminating the need of any connection accessories, the present coupling structure can be convenient and quick. Correspondingly, the disassembly can be convenient as the coupling structure is screw-free. In addition, the coupling structure can be adopted between other boards or panels, such as the left side board and the front side board, the left side board and the rear side board.

Embodiment II

[0050] As shown in FIGS. 6 and 8, in this embodiment, the inclined arm can be V-shaped inclined arm 113. The outer end of the longitudinally extending arm 111 can meet the tip of the V-shaped inclined arm 113. As such, the V-shaped inclined arm 113 and the longitudinally extending arm 111 can jointly form a Y-shaped strip-shaped rib 11. Even with less contact area, the Y-shaped strip-shaped rib can still provide sufficient structural stability for the board coupling structure.

Embodiment III

[0051] As shown in FIGS. 9 to 13, the board coupling structure of this embodiment can comprise a first board 1 and a second board 2 that can be inserted and interlocked into each other. The first board 1 and the second board 2 can be rectangle or square boards. When they are coupled, the first board 1 and the second board 2 can be perpendicular to each other. According to some embodiments, the first board 1 and the second board 2 can be respectively formed with at least one strip-shaped rib 11 and at least one strip-shaped groove 21 that can be inserted or plug-in into each other, so that the first board 1 and the second board 2 can only move in the insertion direction.

[0052] The strip-shaped rib 11 of this embodiment can be disposed on one of the circumferential side surfaces 12 of the first board 1, whereas the strip-shaped groove 21 can be disposed on the inner side wall of the second board 2 and near an edge of the second board 2 along the length direction of the edge. According to some embodiments, the shape of the strip-shaped groove 21 can be adapted to the strip rib 11, with one end of the strip groove 21 forming an opening and the other end being closed. As such, it can facilitate the insertion of the first board 1 and the second board 2 to form the coupling structure.

[0053] According to some embodiments, the circumferential side 12 of the first board 1 can extend outwardly to form a longitudinally extending arm 111 that is perpendicular to the circumferential side 12. In this embodiment, a curved arm 115 can extend from the longitudinally extending arm 111, which can jointly form the stripe-shaped rib 11. According to some embodiments, the curved arm 115 is a S-shaped arm. As shown in FIG. 13, the curved arm 115 can be curved toward both sides of the extension direction of the longitudinally extending arm 111. With the S-shaped shaped cross-section, the contact area between the strip-shaped rib 11 and the stripe-shaped groove 12 is larger. On the one hand, the board coupling structure can improve the bite and make the structure more stable and reliable. On the other hand, it can also facilitate the waterproofing of the connection between the two boards.

[0054] In this embodiment, the first board 1 can be the bottom board of the cabinet, and the second board 2 can be the side board of the cabinet. When interlocking with each other, the first board 1 can be horizontally placed, and then the second board 2 can be placed in a vertical position. A user can backwardly insert the stripe-shaped rib 11 from the open end of the stripe-shaped groove 21 until the rear end of the stripe-shaped rib 11 and the closed end of the stripe-shaped groove 21 abut, thereby completing the coupling of the first board 1 and the second board 2.

[0055] According to some embodiments, the board coupling structure can also be applied to the connection or joint between other adjacent boards of the cabinet. For example, the first board 1 can be the right side board of the cabinet and the second board 2 can be the front side board of the cabinet, which can be interlocked with each other. By eliminating the need of any connection accessories, the present coupling structure can be convenient and quick. Correspondingly, the disassembly can be convenient as the coupling structure is screw-free. In addition, the coupling structure can be adopted between other boards or panels, such as the left side board and the front side board, the left side board and the rear side board.

Embodiment IV

[0056] As shown in FIGS. 14 and 15, in this embodiment, the strip-shaped rib 11 can have a Z-shaped curved arm 113. As the remaining structure can be substantially the same as that of Embodiment III, Embodiment IV is not further described in detail.

Embodiment V

[0057] As shown in FIG. 16, in this embodiment, the strip-shaped rib 11 can have a U-shaped curved arm 114. The U-shaped curved arm 114 can curve toward one side of the extending direction of the longitudinally extending arm 111. It can also increase the contact area between the first board 1 and the second board 2, thereby improving the stability and reliability of the board coupling structure. Furthermore, it can improve the waterproof performance of the board joint.

Embodiment VI

[0058] As shown in FIG. 17, in this embodiment, the strip-shaped rib 11 can have a C-shaped curved arm 115. The C-shaped curved arm 115 can curve toward one side of the extending direction of the longitudinally extending arm 111. As the remaining structure can be substantially the same as that of other Embodiments, Embodiment VI is not further described in detail.

Embodiment VII

[0059] As shown in FIG. 18, in this embodiment, the strip-shaped rib 11 can have a V-shaped curved arm 116. The V-shaped curved arm 116 can curve toward one side of the extending direction of the longitudinally extending arm 111. As the remaining structure can be substantially the same as that of other Embodiments, Embodiment VII is not further described in detail.

Embodiment VIII

[0060] As shown in FIG. 19, in this embodiment, the strip-shaped rib 11 can have a W-shaped curved arm 117. The W-shaped curved arm 117 can curve toward one side of the extending direction of the longitudinally extending arm 111. The W-shaped curved arm 117 can be equivalent to adding another bend to the V-shaped curved arm of Embodiment VII, thereby further increasing the contact area, improving the stability and reliability of the board coupling structure.

[0061] The above are only the preferred embodiments of the present subject matter. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present subject matter, various modifications or improvements can be made to the present subject matter, such as in other applications.
