Abstract

The present subject matter discloses an integrated hinge structure for plastic boards. The integrated hinge structure has a simplified design that is screw-free and convenient to assemble. It also has a relatively lower manufacturing cost. The integrated hinge structure can comprise a first board and a second board that can be coupled to each other. Furthermore, the first board is divided into a first turning portion and a second turning portion by an embedded groove hinge. The second turning portion is further detachably connected to the second board. The integrated hinge structure further comprises fixation features to render the constructed assembly stable and durable.

Claims (23)

1 . An integrated hinge structure for plastic boards, comprising:

a first board ( 1 ) and a second board ( 2 ) configured to be coupled to each other, wherein the first board ( 1 ) is divided into a first turning portion ( 11 ) and a second turning portion ( 12 ) by an embedded groove hinge ( 13 ),

wherein the embedded groove hinge ( 13 ) is in an inner side of the first board ( 1 ); and

wherein the second turning portion ( 12 ) is detachably connected to the second board ( 2 ) via the coupling of first pins ( 123 ) on a receiving side of the second turning portion ( 12 ) and first sockets ( 21 ) on a receiving side of the second board ( 2 ) and the coupling of ribs ( 125 ) on the second turning portion ( 12 ) and corresponding grooves ( 23 ) on the second board ( 2 ).

2 . The integrated hinge structure of claim 1 , wherein the inner side of the first turning portion ( 11 ) has a first inclined surface ( 111 ) connected with one side of the embedded groove hinge ( 13 ), and wherein the inner side of the second turning portion ( 12 ) has a second inclined surface ( 121 ) connected with the other side of the embedded groove hinge ( 13 ).

3 . The integrated hinge structure of claim 2 , wherein the first inclined surface ( 111 ) is configured to abut against the second inclined surface ( 121 ) to prevent the first turning portion ( 11 ) and the second turning portion ( 12 ) from collapsing into each other when the first turning portion ( 11 ) and the second turning portion ( 12 ) are perpendicular to each other.

4 . The integrated hinge structure of claim 1 , wherein the left and right sides of the inner surface of the first turning portion ( 11 ) further comprise inwardly extending stopper stripes ( 112 ), and wherein the left and right sides of the inner surface of the second turning portion ( 12 ) further comprise stopper bars ( 122 ).

5 . The integrated hinge structure of claim 4 , wherein the inwardly extending stopper stripes ( 112 ) are configured to abut against the stopper bars ( 112 ) to prevent the first turning portion ( 11 ) and the second turning portion ( 12 ) from collapsing into each other when the first turning portion ( 11 ) and the second turning portion ( 12 ) are perpendicular to each other.

6 . The integrated hinge structure of claim 1 , wherein each of the first board ( 1 ) and the second board ( 2 ) is a one-piece plastic board.

7 . The integrated hinge structure of claim 1 , wherein the embedded groove hinge ( 13 ) is adjacent to a lower edge of the first board ( 1 ) and disposed along the length direction of the edge.

8 . The integrated hinge structure of claim 1 , wherein the second turning portion ( 12 ) is detachably connected to the second board ( 2 ) via their respective receiving sides.

9 . The integrated hinge structure of claim 8 , wherein the first pins ( 123 ) are disposed along the length direction on the receiving side of the second turning portion ( 12 ) and the first sockets ( 21 ) are disposed along the length direction on the receiving side of the second board ( 2 ), wherein the first pins ( 123 ) are configured to be plugged into the corresponding first sockets ( 21 ).

10 . The integrated hinge structure of claim 9 , wherein the second turning portion ( 12 ) is further detachably connected to the second board ( 2 ) via the coupling of second sockets ( 124 ) disposed along the length direction on the receiving side of the second turning portion ( 12 ) and second pins ( 22 ) disposed along the length direction on the receiving side of the second board ( 2 ), wherein the second pins ( 22 ) are configured to be plugged into the corresponding second sockets ( 124 ).

11 . The integrated hinge structure of claim 10 , wherein the first pins ( 123 ) and the second sockets ( 124 ) are evenly disposed at intervals along the length direction on the receiving side of the second turning portion ( 12 ), and wherein the first sockets ( 21 ) and the second pins ( 22 ) are evenly disposed at intervals along the length direction on the receiving side of the second board ( 2 ).

12 . The integrated hinge structure of claim 11 , wherein the inner wall of the first sockets ( 21 ) and the second sockets ( 124 ) are provided with ribs, and the first pins ( 123 ) and the second pins ( 22 ) are provided with grooves, and wherein the ribs are configured to be snapped into the corresponding grooves when the second turning portion ( 12 ) is connected to the second board ( 2 ).

13 . An integrated hinge structure for plastic boards, comprising:

a first board ( 1 ) and a second board ( 2 ) configured to be coupled to each other, wherein the first board ( 1 ) is divided into a first turning portion ( 11 ) and a second turning portion ( 12 ) by an embedded groove hinge ( 13 ),

wherein the embedded groove hinge ( 13 ) is in an inner side of the first board ( 1 ); and

wherein the second turning portion ( 12 ) is detachably connected to the second board ( 2 ) via their respective receiving sides via the coupling of first pins ( 123 ) on the receiving side of the second turning portion ( 12 ) and first sockets ( 21 ) on the receiving side of the second board ( 2 ) and the coupling of ribs ( 125 ) on the second turning portion ( 12 ) and corresponding grooves ( 23 ) on the second board ( 2 ).

14 . The integrated hinge structure of claim 13 , wherein the second turning portion ( 12 ) is detachably connected to the second board ( 2 ) via the coupling of first pins ( 123 ) disposed along the length direction on the receiving side of the second turning portion ( 12 ) and first sockets ( 21 ) disposed along the length direction on the receiving side of the second board ( 2 ), wherein the first pins ( 123 ) are configured to be plugged into the corresponding first sockets ( 21 ).

15 . The integrated hinge structure of claim 14 , wherein the second turning portion ( 12 ) is further detachably connected to the second board ( 2 ) via the coupling of second sockets ( 124 ) disposed along the length direction on the receiving side of the second turning portion ( 12 ) and second pins ( 22 ) disposed along the length direction on the receiving side of the second board ( 2 ), wherein the second pins ( 22 ) are configured to be plugged into the corresponding second sockets ( 124 ).

16 . The integrated hinge structure of claim 15 , wherein the first pins ( 123 ) and the second sockets ( 24 ) are evenly disposed at intervals along the length direction on the receiving side of the second turning portion ( 12 ), and wherein the first sockets ( 21 ) and the second pins ( 22 ) are evenly disposed at intervals along the length direction on the receiving side of the second board ( 2 ).

17 . The integrated hinge structure of claim 16 , wherein the inner wall of the first sockets ( 21 ) and the sockets ( 124 ) are provided with ribs, and the first pins ( 123 ) and the second pins ( 22 ) are provided with grooves, and wherein the ribs are configured to be snapped into the corresponding grooves when the second turning portion ( 12 ) is connected to the second board ( 2 ).
