For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figures 1-7 The utility model discloses a hidden transmission shutter door, including a door frame 1 and a plurality of blade structures 2 arranged in the door frame 1, wherein both ends of each blade structure 2 along the length direction are rotatably connected to the inner side opposite to the door frame 1, and one end of each blade structure 2 is connected to the same transmission rod 4 through a connecting component 3, so that when one of the blade structures 2 rotates, the other blade structures 2 rotate synchronously; wherein the transmission rod 4 is hidden in the door frame 1.

[0031] The hidden transmission shutter door of this embodiment connects one end of multiple blade structures 2 to the same transmission rod 4 through a connecting assembly 3, so that when one of the blade structures 2 rotates, the other blade structures 2 rotate synchronously; specifically, when one of the blade structures 2 is manually moved, the other blade structures 2 rotate synchronously under the transmission of the transmission rod 4, so that the shutter blades are opened, and the synchronous rotation of all the blades in the shutter door can be achieved without an electric drive mechanism; at the same time, the linkage components in the utility model, such as the transmission rod 4, the connecting assembly 3, etc., are all hidden in the door frame 1, which is not only simple and beautiful in structure, but also not easy to be damaged.

[0032] Specifically, Figure 2 and Figure 3As shown, the connecting component 3 includes a first connecting member 301, a second connecting member 302 and a short rod 303, the first connecting member 301 is fixedly arranged in the door frame 1; the second connecting member 302 includes a first end 3021 and a second end 3022, the first end 3021 is fixedly connected to the blade structure 2, the second end 3022 passes through the first connecting member 301 and is fixedly connected to one end of the short rod 303, the other end of the short rod 303 is hingedly connected to the transmission rod 4, and the second connecting member 302 can rotate relative to the first connecting member 301. In this embodiment, the first connecting member 301 can play a role similar to that of a bearing, thereby not affecting the rotation of the second connecting member 302; and the second connecting member 302 plays a role of rotation. When the blade structure 2 rotates, since the second connecting member 302 is fixedly connected to the blade structure 2, the second connecting member 302 will also rotate along with the blade structure 2; similarly, the short rod 303 will also rotate along with the second connecting member 302. At this time, since the other end of the short rod 303 is hinged to the transmission rod 4, during the process of the short rod 303 rotating around the second connecting member 302, the transmission rod 4 will be pushed to move upward or downward at the same time; and during the process of the transmission rod 4 moving upward or downward, since the transmission rod 4 is connected to the short rod 303, the short rod 303 will also rotate along with the movement of the transmission rod 4, thereby driving the second connecting member 302 connected to the short rod 303 and the blade structure 2 to rotate, thereby realizing the synchronous rotation of all blades in the shutter door, and then opening or closing the shutter door.

[0033] The short rod 303 and the transmission rod 4 are connected by a screw 306. When one of the blade structures 2 is manually moved to open the shutter door, the short rod 303 rotates around the second connecting member 302, and at the same time, the transmission rod 4 will be pushed to move upward. At this time, the transmission rod 4 will rotate relative to the screw 306, so that the transmission rod 4 and the screw 306 are gradually tightened. When the transmission rod 4 and the screw 306 are tightened, the shutter door can be in an open state; and when one of the blade structures 2 is manually moved to close the shutter door, the transmission rod 4 and the screw 306 rotate in the opposite direction under the force of the rotation of the short rod, so that the transmission rod 4 and the screw 306 are loosened, and under the transmission action of the transmission rod 4, the second connecting member 302 and the blade structure 2 connected to the other short rod 303 are driven to rotate, so that the shutter door is in a closed state. The state diagram when closed can be shown as follows: Figure 1 As shown, the state diagram when opening can be as follows Figure 8 shown.

[0034] In addition, Figure 8 As shown, the shape of the blade structure 2 can be approximately an elliptical structure or an arc structure, so as to enhance the overall shape of the shutter door and window and provide a decorative effect.

[0035] Further, such as Figures 4-6As shown, the blade structure 2 is a hollow structure. A first limiting groove 201 matching the shape of the first end 3021 is provided in the hollow structure. The first end 3021 is limited and fixed in the first limiting groove 201. By limiting the first end 3021 through the first limiting groove 201, the fixed connection between the first end 3021 and the blade structure 2 is realized. In this embodiment, the shape of the first end 3021 is preferably a square structure. Then, it is only necessary to provide the first limiting grooves 201 matching the size of the square structure on the upper and lower blades of the blade structure 2 respectively. Since the two ends of the blade structure 2 are already limited in the door frame 1 at this time, only the first limiting groove 201 needs to be a long strip and the size matches the square structure of the first end 3021, so as to realize the fixed connection between the first end 3021 and the blade structure 2. At this time, when the blade structure 2 rotates, the first end 3021 will also rotate synchronously.

[0036] As Figure 3 shown, a through hole 3031 matching the shape of the second end 3022 is provided at one end of the short rod 303. The second end 3022 is sleeved in the through hole 3031 and fixedly connected through a fastener 304. Specifically, after the second end 3022 is sleeved in the through hole 3031, a gasket 305 is provided on the outer sides of the second end 3022 and the short rod 303, and the outer diameter of the gasket 305 is larger than the inner diameter of the through hole 3031. Finally, the fastener 304 penetrates through the gasket 305 and the second end 3022 to realize the fixed connection between the second end 3022 and the short rod 303. When the second end 3022 rotates, the short rod 303 will also rotate synchronously at this time.

[0037] Preferably, as Figure 3 shown, the second end 3022 is a polygonal structure or an irregular shape structure, so that when the second end 3022 rotates, the short rod 303 also rotates synchronously.

[0038] In this embodiment, through the structural design of the above connection component 3, while enabling all blade structures 2 to rotate synchronously, the structure of the louver door is also greatly simplified. The linkage structure design in this embodiment of the louver door is simple and easy to install, greatly reducing the production cost of the louver door.

[0039] Furthermore, as Figure 7As shown in the figure, on the side of the door frame 1 facing away from the blade structure 2, there is a placement groove 101, and in the placement groove 101, there is a decorative cover 102 for covering the connection component 3 and / or the transmission rod 4. In this embodiment, by setting the placement groove 101, the connection component 3 and the transmission rod 4 can be arranged in the placement groove 101 to achieve the hidden installation of the linkage components, making the overall structure appearance of the shutter door simple and generous, and not easily damaged. In addition, when the shutter door fails, it can also be repaired by disassembling the decorative cover 102, which is beneficial for both repair and installation.

[0040] Preferably, as Figure 5 and Figure 6 shown in the figure, on one side of the blade structure 2, a first extension 202 extends outward. Along the length direction of the blade structure 2 on the first extension 202, there is a second limiting groove 203, and a rubber strip 5 is arranged in the second limiting groove 203; on the side of the blade structure 2 opposite to the first extension 202, a second extension 204 extends outward; the end of the second extension 204 can be hermetically connected to the rubber strip 5 installed on the adjacent blade structure 2. In this embodiment, by respectively arranging the first extension 202 and the second extension 204 on the opposite sides of the blade structure 2 and on different planes (for example, the first extension 202 is close to or on the side of the bottom surface of the blade structure 2, while the second extension 204 is close to or on the side of the top surface of the blade structure 2), when the blade structure 2 is closed, the second extensions 204 and the first extensions 202 on two adjacent blade structures 2 are arranged in parallel. At this time, the rubber strip 5 just abuts against the second extensions 204 and the first extensions 202 of the two adjacent blade structures 2. And, due to the function of the rubber strip 5, when it rains, rainwater is not easily introduced into the room from the gap between the two blade structures 2.

[0041] Furthermore, as Figure 5 and Figure 6 shown in the figure, the outer surface of the rubber strip 5 is a vertical surface structure, and preferably a circular arc shape specifically, so that when the blade structure 2 is closed, when the second extension 204 presses against the vertical surface of the rubber strip 5, a better waterproof effect can be achieved.

[0042] In addition, as Figure 7 shown in the figure, along the length direction at the connection between the door frame 1 and the blade structure 2, there is a third limiting groove 103, and a first felt strip 6 is arranged in the third limiting groove 103, which can effectively prevent rainwater from entering the room from the connection between the door frame 1 and the blade structure 2, thereby achieving a better sealing and waterproof effect.

[0043] Furthermore, as Figure 1 and Figure 7As shown, on the outer side of the door frame 1, fourth limiting grooves 104 are respectively provided along the length direction, and second wool strips 7 are arranged in the fourth limiting grooves 104. In this embodiment, by arranging the second wool strips 7 on the outer side of the door frame 1, rainwater is prevented from entering the room through the gaps between the door frame 1 and other door frames 1 or the wall, and the waterproof effect is better.

[0044] The foregoing are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
