Figure 2 、 Figure 4 and Figure 7 As shown, the pivot structure further comprises a second connecting piece 4, which is rotatably connected to the rotating shaft 1, and the second connecting piece 4 is provided with a second elastic part 5, and the second connecting piece 4 can be connected to the second door body 7 through the second elastic part 5; the second elastic part 5 is used for at least applying a buffering force to the first door body 6 in the process that the second connecting piece 4 drives the second door body 7; the first connecting piece 2 and the first elastic part 3 are located on the left side of the rotating shaft 1, and the second connecting piece 4 and the second elastic part 5 are located on the right side of the rotating shaft 1. In this technical solution, the second door body 7 acted on by the second connecting piece 4 is a fixed door body, and the first door body 6 acted on by the first connecting piece 2 is a movable door body; the first connecting piece 2 and the second connecting piece 4 are symmetrically arranged, and in this embodiment, the first connecting piece 2 is connected to one end of the rotating shaft 1 and the second connecting piece 4 is connected to one end of the rotating shaft 1, which are arranged in a staggered manner, and both can rotate around the rotating shaft; the second connecting piece 4 connected to the second door body 7 is fixed relative to the first connecting piece 2.

[0033] The second connecting piece 4 has a first position and a second position relative to the first connecting piece 2. When in the first position, the first connecting piece 2 rotates around the rotating shaft 1 until the second connecting piece 4 is clamped with the first connecting piece 2, and the hinge is in a folded state. At this time, the first connecting piece 2 is clamped in the second connecting piece 4, and no matter how the user acts on the first door body 6 connected with the first connecting piece 2, the first door body 6 will not collide with the second door body 7, avoiding the defects that the first door body 6 and the second door body 7 are unstable when in the folded state, the first door body 6 is easily bounced away, the user needs to act on the first door body 6, and the first door body 6 and the second door body 7 will be continuously collided to affect the use. When in the second position, the first connecting piece 2 rotates in the opposite direction around the rotating shaft 1, and the second connecting piece 4 is separated from the first connecting piece 2. The hinge naturally unfolds until the first connecting piece 2 and the second connecting piece 4 of the hinge abut each other and reset to the same horizontal line. At this time, the first door body 6 and the second door body 7 are in a closed state, which is simple and convenient, and gives the user a good product experience.

[0034] Specifically, as shown in the drawings, Figure 2 The first connecting piece 2 has a first clamping part 201, and the second connecting piece 4 has a second clamping part 401. The first clamping part 201 is oppositely arranged, and the first clamping part 201 or the second clamping part 401 has a guide groove 8 that can be matched and installed with the outer edge of the first clamping part 201 or the second clamping part 401. When the first connecting piece 2 or the second connecting piece 4 rotates around the rotating shaft 1, the outer edge of the second clamping part 401 or the first clamping part 201 can be adaptively clamped in the guide groove 8 to achieve folding.

[0035] When the outer edge of the first clamping part 201 or the second clamping part 401 is away from the guide groove 8, the second elastic part 5 drives the second connecting piece 4 to rotate, and the second connecting piece 4 drives the first connecting piece 2 to a natural state, assisting the first elastic part 3 to restore the natural state. At this time, the first door body 6 slowly and automatically reaches the same horizontal line with the second door body 7, restoring the closed door state, reducing the mutual collision of the first door body 6 and the second door body 7, and reducing the generation of noise.

[0036] The assembly relationship between the second connecting piece 4 and the rotating shaft 1 is shown in Figure 3 and Figure 4As shown, the second connecting piece 4 comprises a second mounting edge 41 and a second hinge shaft 42, the second mounting edge 41 is provided with a second mounting hole 411, the rotating shaft 1 is arranged in the second mounting hole 411; the end of the second mounting edge 41 away from the second mounting hole 411 is provided with a second hinge hole 412, and the second hinge shaft 42 is arranged in the second hinge hole 412. In this embodiment, the second mounting edge 41 of the second connecting piece 4 is provided with the second mounting hole 411, the rotating shaft 1 is arranged in the second mounting hole 411, the second mounting edge 411 can rotate around the rotating shaft 1 to drive the second hinge shaft 42 to rotate.

[0037] It should be noted that the second elastic part 5 in this embodiment has the same structure as the first elastic part 3, and the specific embodiment is shown in Figure 6

[0038] The second elastic part 5 also comprises a first abutting plate, a second abutting plate and a spring, the second abutting plate is fixedly covered on the first abutting plate to form a containing cavity capable of containing the spring, one end of the spring is fixedly connected with the upper wall surface (i.e. the first abutting plate) of the containing cavity, and the other end of the spring is fixedly connected with the lower wall surface (i.e. the second abutting plate) of the containing cavity, and the second abutting plate is vertically arranged on the second hinge shaft 42, and the second abutting plate is fixedly sleeved on the abutting hinge shaft 42; the pivot structure in this embodiment further comprises a second acting plate 103 and a second cover plate 104, and the specific embodiment is shown in Figure 2 The second cover plate 104 is fixedly covered on the second acting plate 103; the second mounting edge 41 is welded on the second acting plate 103, one side of the second elastic part 5 is suspended on the second acting plate 103; the other side of the second elastic part 5 is fixedly installed on the second cover plate 104, thereby limiting the moving position of the second elastic part 5.

[0039] As shown in Figure 2 In this embodiment, the second door body 7 is a fixed door body, the first door body 6 is a movable door body, the second connecting piece 4 constitutes part of the first clamping part 201, and the first connecting piece 2 constitutes part of the second clamping part 401; the first connecting piece 2 can drive the first clamping part 201 to rotate, the second clamping part 401 can limit the rotation angle of the first clamping part 201, so that the second elastic part 5 can drive the first door body 6 to close the second door body 7.

[0040] ​When the first door 6, which is operated by the first connector 2, is opened, the first mounting edge 21 of the first connector 2 rotates around the pivot 1, the hinge shaft 21 rotates together, and the second abutment plate 32, which is fixedly connected to the hinge shaft 21, also rotates together. The end of the first connector 2 away from the hinge shaft 22 is the first locking part 201, which also rotates along with it, pulling the end of the second connector 4 away from the second hinge shaft 42 to move in the opposite direction. The end of the second connector 4 away from the second hinge shaft 42 is the second locking part 401. At this time, the spring in the second elastic part 5 connected to the second connector 4 stretches, pulling the second locking part 401 in turn. Since the second connector 4 is part of the first locking part 201, it indirectly drives the first elastic part 5 to compress, giving resistance to the second door 7. The first elastic part 5 pulls the second connector 4, thereby pulling the first connector 2 to return to its original state, helping the first elastic part 3 to pull the first door 6 back to its natural state, automatically placing it on the same horizontal line as the second door 7 (i.e., both doors are in the closed state).

[0041] Preferably, by Figure 3 As shown, the second mounting edge 41 of the second connector 2 has a C-shaped structure, which facilitates easy installation. The second mounting edge 41 does not get stuck during the makeup application process, and the structure is stable, providing users with a good product experience.
