DETAILED DESCRIPTION

[0030] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] like Figure 1-4 As shown, a hinge mechanism for a belly plate includes: a first hinge plate 1, a second hinge plate 11 arranged on one side of the first hinge plate 1, and a plurality of fan-shaped movable grooves 2 opened on the top of the first hinge plate 1 and the second hinge plate 11; a cylindrical groove 21 is opened on the inner side of the first hinge plate 1 and the second hinge plate 11, and connecting grooves 22 are opened at both ends of the cylindrical groove 21, and the plurality of fan-shaped movable grooves 2 and the connecting grooves 22 are connected with the inside of the cylindrical groove 21.

[0032] A plurality of hinge blocks 3 are clamped on the inner sides of the fan-shaped movable grooves 2, a rotating rod 4 is arranged inside the cylindrical groove 21, the side of the rotating rod 4 is fixed to the inner sides of the plurality of hinge blocks 3, and a clockwork spring 5 is arranged on the side of the rotating rod 4 located inside the connecting groove 22.

[0033] It should be noted that the two ends of the rotating rod 4 are rotatably connected to the inner side of the connecting groove 22 through bearings; the two ends of the hinge block 3 are respectively located on the inner side of the fan-shaped movable groove 2 on the first hinge plate 1 and the fan-shaped movable groove 2 on the second hinge plate 11; one end of the clockwork spring 5 is fixed to the side of the rotating rod 4, and the other end is fixed to the inner side of the connecting groove 22; the cylindrical groove 21 and the connecting groove 22 are both coaxially arranged with the fan-shaped movable groove 2; a plurality of the fan-shaped movable grooves 2 are evenly distributed on the top of the first hinge plate 1 and the second hinge plate 11 in a linear array; when the first hinge plate 1 and the second hinge plate 11 are in a folded state, the clockwork spring 5 is in an initial state; through the cooperation of a plurality of hinge blocks 3, since the two ends are respectively located on the inner side of the fan-shaped movable groove 2 on the first hinge plate 1 and the fan-shaped movable groove 2 on the second hinge plate 11, when in contact with a plurality of fan-shaped movable grooves 2 With the cooperation of the rotating rod 4 in the cylindrical groove 21 connected to the movable groove 2, the position of the hinge block 3 can be fixed on the inner side of the fan-shaped movable groove 2, so that it can complete the hinge effect at both ends, and it is a hidden design without protrusions to avoid affecting the use effect of the belly plate. When switching from the unfolded state to the folded state, with the rotating rod 4 as the center of the circle, the second hinge plate 11 is flipped to drive a plurality of hinge blocks 3, and flipped from the top of the first hinge plate 1 to one side in a plurality of fan-shaped grooves. While flipping, the rotating rod 4 will rotate in the connecting groove 22 and the cylindrical groove 21, and the spring 5 will reset to the initial state, thereby flipping the first hinge plate 1 and the second hinge plate 11 to fold. With the cooperation of the spring 5 in the connecting groove 22 connected to the cylindrical groove 21, the rotation limit of the posture of the rotating rod 4 at this time can be realized, so that the folded state is self-locked, and then under the influence of external forces and other factors, it is not easy to cause folding failure.

[0034] The corresponding sides of the top of the first hinge plate 1 and the top of the second hinge plate 11 are both arc-shaped; through this design, the switching from the unfolded state to the folded state, or the switching from the folded state to the unfolded state, can be smoother.

[0035] like Figure 5 As shown, the top of the first hinge plate 1 is provided with a plurality of clamping components for limiting the posture when the top of the first hinge plate 1 and the top of the second hinge plate 11 are in contact. The clamping components include: a moving groove 6 provided on one side of the first hinge plate 1, a shifting block 61 provided on the inner side of the moving groove 6, and a clamping groove 62 provided on the inner side of the second hinge plate 11; one end of the shifting block 61 is located on one side of the first hinge plate 1, a clamping block 63 is fixed on one side of the shifting block 61 located inside the moving groove 6, and a return spring 64 is fixed on the other side, and one end of the return spring 64 is fixed to the inner side of the moving groove 6.

[0036] It should be noted that the slot 62 corresponds to the position of the movable slot 6 and is connected to the inside of the movable slot 6. The shape and size of the slot 62 are the same as the shape and size of the block 63. When the first hinge plate 1 and the second hinge plate 11 are switched from the folded state to the unfolded state, due to the influence of the restoring force of the spring 5, the first hinge plate 1 and the second hinge plate 11 will have a rebound folding force. Before the top of the first hinge plate 1 is aligned with the top of the second hinge plate 11, the block 61 is moved to drive The block 63 moves toward the inner side of the movable groove 6, and then squeezes the return spring 64. When the top of the first hinge plate 1 is aligned with the top of the second hinge plate 11, the slot 62 and one end of the movable groove 6 are also synchronously aligned, canceling the force on the shift block 61. The return spring 64 will reset and squeeze the shift block 61, driving the block 63 on one side of the shift block 61 to be connected to the inner side of the slot 62, which can play a connection limit effect, thereby avoiding the rebound force causing it to fold again. When applied to the abdominal plate, the reliability and stability are improved.

[0037] A belly plate device includes a hinge mechanism and two belly plates; the two belly plates are fixed to one side of a first hinge plate 1 and a second hinge plate 11, respectively, so that the belly plates at both ends can be flipped open and closed by the hinge mechanism, so as to achieve the effect of unfolding and using a foldable storage box. The hinge mechanism is the hinge mechanism disclosed in the above embodiment, so the belly plate device with the hinge mechanism also has all the above technical effects, which will not be described one by one here.

[0038] When the utility model is used, when switching from the unfolded state to the folded state, the second hinge plate 11 is flipped with the rotating rod 4 as the center of the circle to drive the plurality of hinge blocks 3 to flip from the top of the first hinge plate 1 to one side in the plurality of fan-shaped grooves. While flipping, the rotating rod 4 will rotate in the connecting groove 22 and the cylindrical groove 21, and the spring 5 will reset to the initial state, thereby flipping the first hinge plate 1 and the second hinge plate 11 to fold. With the cooperation of the spring 5 in the connecting groove 22 connected to the cylindrical groove 21, the rotation limit of the rotating rod 4 at this time can be realized, so that the folded state is self-locked. When the first hinge plate 1 and the second hinge plate 11 are switched from the folded state to the unfolded state, due to the reset force of the spring 5 Under the influence, the first hinge plate 1 and the second hinge plate 11 will have a rebound folding force. Before the top of the first hinge plate 1 is aligned with the top of the second hinge plate 11, the shift block 61 is pushed to drive the card block 63 to move to the inner side of the movable groove 6, and then the return spring 64 will be squeezed. When the top of the first hinge plate 1 is aligned with the top of the second hinge plate 11, the card slot 62 and one end of the movable groove 6 will also be synchronously aligned, and the force on the shift block 61 will be cancelled. The return spring 64 will reset and squeeze the shift block 61, and drive the card block 63 on one side of the shift block 61 to be clamped on the inner side of the card slot 62, which can play a connection limit effect, thereby avoiding the rebound force to cause it to fold again. When applied to the abdominal plate, the reliability and stability are improved.
