Referring to fig. 1, fig. 1 shows a structure of a folding fan-shaped door in an embodiment of the present invention. The present embodiment provides a folding fan-shaped door 100, and the folding fan-shaped door 100 is used for being connected with a door frame 210 to close or open an opening on the door frame 210. And the opening and closing of the door referred to hereinafter means that the opening of the door frame 210 is opened and closed, respectively.
Specifically, the folding sector door 100 includes a handle structure 110, a rack 120, a door bin 130, and a sector door group 140.
Wherein, a part of the rack 120 extends into the door bin 130, and the sector door group 140 is rotatably connected with the rack 120 positioned in the door bin 130. It should be noted that the purpose of extending the portion of the rack 120, which is used for being rotatably connected with the door segment group 140, into the door bin 130 is to enable the door segment group 140 to be fully rotated into the door bin 130 during the rotation of the door segment group 140.
Referring to fig. 2 and 3, fig. 2 and 3 show a structure of a handle structure in an embodiment of the present invention. The handle structure 110 includes a door handle 111 and a connecting rod 112, the door handle 111 and the rack 120 are slidably connected to the rack 120, one end of the connecting rod 112 is connected to the door handle 111, and the other end of the connecting rod 112 is rotatably connected to the sector door group 140; in such a setting mode, the purpose is to drive the sector door group 140 to rotate through the linear movement of the door handle 111, so as to further realize the storage and the expansion of the sector door group 140, thereby playing a role in simplifying the operation mode.
The door handle 111 slides relative to the frame 120 under the action of an external force, and drives the fan-shaped door group 140 to move relative to the door bin 130 through the connecting rod 112, so that the folding fan-shaped door 100 has an unfolded state in which the fan-shaped door group 140 is unfolded outside the door bin 130, and a stored state in which the fan-shaped door group 140 is stored in the door bin 130.
Referring to fig. 1 to 3, the operation principle of the folding fan-shaped door 100 is as follows:
the folding fan-shaped door 100 controls the portion of the fan-shaped door extending out of or into the door bin 130 through the movement of the fan-shaped door group 140 relative to the door bin 130 under the action of external force, thereby controlling the size of the opening of the door frame 210 connected with the folding fan-shaped door 100 and further realizing the actions of opening and closing the door. In the process, the door opening and closing are realized by rotating the folding fan-shaped door 100 around the rotating connection part with the rack 120 relative to the door bin 130, so that the rotating space and the rotating radius can be effectively reduced, and the use is convenient. In addition, in the rotating process of the sector door group 140, the part of the sector door group 140 rotating into the door bin 130 can be controlled through external force, and then the size of the part outside the door bin 130 can be controlled, so that the size of the closed door frame 210 of the folding sector door 100 can be controlled, and the degree of opening the door can be controlled, and the use is facilitated.
Specifically, the sector door set 140 of the folding sector door 100 is rotatably connected to the frame 120, and the sector door set 140 is connected to the handle structure 110, so that it can rotate relative to the frame 120 under the driving action of the handle structure 110. And during rotation of the door sector 140 relative to the frame 120, it may rotate relative to the door bin 130.
When the door needs to be closed, the handle structure 110 is driven by external force to move, so that the fan-shaped door group 140 is driven by the handle structure 110 to expand towards the outside of the door bin 130 relative to the door bin 130, and at the moment, the fan-shaped door group 140 is in an expanded state, so that the door frame 210 can be closed to close the door;
when the door needs to be opened, the handle structure 110 is driven to move by external force so as to drive the fan-shaped door group 140 to rotate towards the door bin 130 relative to the door bin 130, and at the moment, the fan-shaped door group 140 is in a storage state, so that the door frame 210 can be opened to open the door;
in the process of opening and closing the door, the handle structure 110 can be used to adjust the portion of the fan-shaped door set 140 rotating into the door bin 130, so as to control the opening and closing degree of the fan-shaped door set 140, and adjust the size of the opening of the door.
In summary, the folding fan-shaped door 100 can control and adjust the unfolding and storage states of the fan-shaped door group 140 relative to the door bin 130 by means of the fan-shaped door group 140 under the driving action of the handle structure 110, so that the door body arrangement mode can effectively reduce the space requirement and the door opening radius required by the door body to open the door, and meanwhile, the opening and closing degree of the door body is controlled, so that the door body is convenient to use.
Further, referring to fig. 1-3, in order to facilitate the handle structure 110 to move the door segment 140, the handle structure 110 further includes a sliding slot 113 disposed on the frame 120, the door handle 111 is partially slidably disposed in the sliding slot 113, and in order to facilitate the sliding slot 113 to cooperate with the door handle 111, the sliding slot 113 is disposed on a portion of the frame 120 located outside the door bin 130. Therefore, the sliding groove 113 can guide the movement of the handle, and the door can be opened and closed conveniently. In addition, when the sliding slot 113 is disposed, it is required to satisfy that the linear motion of the door handle 111 in the sliding slot 113 can drive the motion of the sector door set 140 within the door opening and closing range, that is, the motion range of the door handle 111 in the sliding slot 113 is enough to drive the sector door to switch between the unfolding state and the storage state, so as to complete the door opening and closing actions.
It should be noted that, in the present embodiment, the fan-shaped door group 140 is a foldable fan-shaped door structure, which can be stacked together under the action of external force, and because the volume and the surface area after stacking are reduced, the door can be conveniently stored and opened; similarly, it can be unfolded by external force, and its surface area is increased to perform door closing action.
For the above reasons, please refer to fig. 1-3, and fig. 1-3 illustrate the structure of the sectoral door assembly according to the embodiment of the present invention. When the sector door group 140 is provided, the sector door group 140 may include a plurality of sector door bodies 141 and a rotating shaft 142. The fan-shaped door bodies 141 are all connected with the rotating shaft 142, and the rotating shaft 142 is connected with the rack 120 located in the door bin 130. Accordingly, the plurality of fan-shaped door bodies 141 can be stacked or unfolded by the rotation of the plurality of fan-shaped door bodies 141 by the external force, so as to adapt to the door opening and closing process.
Further, when a plurality of fan-shaped door bodies 141 are provided, the connecting rod 112 of the handle structure 110 needs to be rotationally connected with one of the fan-shaped door bodies 141, so that when the connecting rod 112 receives an external force, the plurality of fan-shaped door bodies 141 can be driven to rotate relative to the rotating shaft 142 through the movement of the connecting rod 112, and the plurality of fan-shaped door bodies 141 are stacked or sequentially unfolded.
Therefore, when the folding fan-shaped door 100 is in a storage state, the folding fan-shaped door can drive the fan-shaped door bodies 141 to be sequentially stacked in the door bin 130; and when the folding fan-shaped door 100 is in the unfolding state, the fan-shaped door bodies 141 are driven to be sequentially unfolded outside the door bin 130.
Further, in order to enable the link 112 to drive the fan-shaped door body 141 to rotate relative to the rotating connection between the fan-shaped door body 141 and the rack 120, the link 112 and the rotating shaft 142 are spaced at the rotating connection on the same fan-shaped door body 141.
As can be seen from the above, in this embodiment, the sector door group 140 includes a storage state stacked with each other and an expansion state expanded in sequence under the action of an external force, in order to enable the sector door group 140 to be switched between the two states, it is necessary to enable any one of the sector door bodies 141 to move in two directions under the driving of the adjacent sector door body 141, that is, any one of the sector door bodies 141 can rotate clockwise (or counterclockwise) around the rotational connection between the sector door body 141 and the rack 120 under the driving of the sector door body 141 adjacent thereto, so that the two adjacent sector door bodies 141 can be stacked with each other to move to the storage state; similarly, any one of the sector door bodies 141 can also rotate around the rotation joint of the sector door body 141 and the rack 120 in the counterclockwise direction (or clockwise direction) under the driving action of the adjacent sector door body 141, so that the two adjacent sector door bodies 141 can be unfolded mutually to move to the unfolded state.
Referring to fig. 2 and 4, fig. 2 and 4 show a structure of a limiting structure in an embodiment of the present invention. Along the stacking direction of the fan-shaped door bodies 141, a limiting structure 150 is arranged between two adjacent fan-shaped door bodies 141, and the limiting structure 150 is used for driving one fan-shaped door body 141 adjacent to the one fan-shaped door body 141 to rotate around the rotating shaft 142 when the one fan-shaped door body 141 rotates around the rotating shaft 142, and the rotating direction of the limiting structure can be clockwise or counterclockwise.
Specifically, the limiting structure 150 may include a first limiting block 151 and a second limiting block 152; the first limiting block 151 and the second limiting block 152 are respectively disposed on the opposite side surfaces of the two adjacent fan-shaped door bodies 141, and the first limiting block 151 is used for abutting against the second limiting block 152, so that when the fan-shaped door body 141 provided with the first limiting block 151 rotates along the unfolding direction, the fan-shaped door body 141 provided with the second limiting block 152 adjacent to the first limiting block 151 is driven to rotate along the unfolding direction.
In addition, along the unfolding direction of the fan-shaped door group 140, the first stopper 151 and the second stopper 152 are respectively arranged at two sides of the fan-shaped door body 141; when there is an adjacent sector door 141, the first stopper 151 and the second stopper 152 are respectively disposed on the surfaces of the sector door 141 and the adjacent sector door 141 along the unfolding direction of the sector door group 140. In the unfolding direction of the fan-shaped door group 140, the first stopper 151 and the second stopper 152 are located at two sides of the fan-shaped door body 141 or the fan-shaped door body 141 adjacent to the fan-shaped door body 141.
It should be noted that, based on the above principle, the limiting structure 150 further includes a third limiting block and a fourth limiting block, the third limiting block is used for cooperating with the fourth limiting block to drive the two adjacent fan-shaped door bodies 141 to move in the accommodating direction, and the action principle of the third limiting block and the fourth limiting block is the same as that described above, so that the description is omitted here.
