DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0023] The utility model provides a farm shutter air inlet, the structure of which is as follows Figure 1 - Figure 2 As shown, it includes a shutter mechanism 1 and an opening and closing mechanism 2.
[0024] The shutter mechanism 1 includes a window frame 11 and a plurality of blades 12 rotatably connected to the window frame 11 along the height direction of the window frame 11 .
[0025] The opening and closing mechanism 2 includes a main rope 21 and a secondary rope 22. The main rope 21 is slidably passed through the top of the window frame 11. The window frame 11 is provided with a driving component 3 for driving the main rope 21 to move. One end of the secondary rope 22 is connected to the main rope 21. One side of the multiple fan blades 12 is connected together through a connector 4, and the other end of the secondary rope 22 is connected to the connector 4.
[0026] During use, when the Venetian blinds need to be opened or closed, the drive assembly 3 on the window frame 11 is activated. The operation of the drive assembly 3 drives the main rope 21 to move. Since the main rope 21 slides through the top of the window frame 11, the movement of the main rope 21 pulls or pushes the secondary rope 22 connected to it. One end of the secondary rope 22 is connected to the main rope 21, and the other end is connected to the connector 4 on one side of the multiple blades 12. When the secondary rope 22 moves, it drives the multiple blades 12 to move together through the connector 4. When the main rope 21 moves in one direction under the action of the drive assembly 3, the secondary rope 22 pulls the connector 4, causing the blades 12 to rotate along the height direction of the window frame 11, thereby opening or closing the Venetian blinds.
[0027] In the present invention, under the driving action of the driving component 3, under the transmission action of the main rope 21, the auxiliary rope 22 and the connector 4, the opening and closing of multiple blades 12 on multiple blinds can be controlled at the same time, the operation is simple, the operation is reliable, and the work efficiency is improved.
[0028] To open and close the fan blades 12, please refer to Figure 1 In a preferred embodiment, the driving assembly 3 includes a winch 31 provided on one side of the window frame 11 , one end of the main rope 21 is wound around the winch 31 , and a counterweight 32 is provided at the other end of the main rope 21 .
[0029] During use, when the blinds need to be opened or closed, the winch 31 on one side of the window frame 11 is rotated. When the winch 31 rotates forward, the main rope 21 is wound around the winch 31, and one end of the main rope 21 is gradually shortened. Since the other end of the main rope 21 is provided with a counterweight 32, when the winch 31 reels the main rope 21, the gravity of the counterweight 32 helps the main rope 21 to maintain a taut state and ensures that the main rope 21 moves more smoothly. As the main rope 21 is wound around the winch 31, the main rope 21 pulls the auxiliary rope 22, which drives the fan blades 12 to rotate through the auxiliary rope 22 and the connector 4, thereby achieving the closing action of the blinds. When the winch 31 rotates in the reverse direction, the main rope 21 wound around it is gradually released. Under the gravity of the counterweight 32, the main rope 21 is pulled downward, achieving the opening action of the blinds.
[0030] In order to make the main rope 21 slide more smoothly along the top of the window frame 11, please refer to Figure 2 In a preferred embodiment, the top of the window frame 11 is rotatably connected to a roller 23, and the main rope 21 is overlapped on the top of the roller 23.
[0031] During operation, the main rope 21 moves along the top of the window frame 11 to open and close the Venetian blinds. Because the top of the window frame 11 is rotatably connected to a roller 23, the main rope 21 laps over the top of roller 23. When the drive assembly 3 moves the main rope 21, roller 23 rotates accordingly. The rotation of roller 23 significantly reduces the friction between the main rope 21 and the top of the window frame 11, allowing the main rope 21 to move more smoothly and reducing wear on the main rope 21. It also reduces the power required by the drive assembly 3, making the opening and closing of the Venetian blinds easier, more flexible, and more efficient.
[0032] In order to achieve the synchronous opening and closing of multiple fan blades 12, please refer to Figure 2 In a preferred embodiment, the connector 4 includes a connecting plate 41 provided on one side of the fan blade 12, and a rotating rod 42 is rotatably connected to the connecting plate 41. Multiple rotating rods 42 are commonly connected to a connecting rod 47, and a pull ring 43 is provided at the end of the connecting rod 47. The end of the auxiliary rope 22 is connected to the pull ring 43.
[0033] During use, when the shutters need to be opened and closed, the main rope 21 moves under the action of the drive assembly 3, thereby pulling the auxiliary rope 22. The end of the auxiliary rope 22 is connected to the pull ring 43 at the end of the connecting rod 47. When the auxiliary rope 22 moves, the force will be transferred to the pull ring 43, and then to the connecting rod 47. Since multiple rotating rods 42 are connected to the connecting rod 47, and the rotating rod 42 is rotatably connected to the connecting plate 41 on one side of the fan blade 12, the movement of the connecting rod 47 will drive the rotating rod 42 to rotate. The rotation of the rotating rod 42 will drive the connecting plate 41, and then drive the fan blade 12 to rotate along the height direction of the window frame 11, thereby realizing the opening or closing action of the shutters. Through the structural design of this connector 4, the pulling force or thrust of the auxiliary rope 22 can be evenly transferred to each fan blade 12, so that multiple fan blades 12 rotate synchronously, ensuring the consistency and stability of the opening and closing of the shutters.
[0034] In order to firmly fix the rotating rod 42 and the connecting rod 47 together, please refer to Figure 2 In a preferred embodiment, the rotating rod 42 is provided with a through hole 44 for the connecting rod 47 to pass through, the rotating rod 42 is provided with a threaded hole 45, the threaded hole 45 is internally threaded with a bolt 46, and the connecting rod 47 is provided with a receiving groove for accommodating the bolt 46.
[0035] During use, during the opening and closing operation of the Venetian blinds, when the auxiliary rope 22 pulls or pushes the connecting rod 47, the connecting rod 47 moves in the through hole 44 of the rotating rod 42. A bolt 46 is threadedly connected to the threaded hole 45 on the rotating rod 42, and the end of the bolt 46 is located in the receiving groove on the connecting rod 47. The cooperation between the bolt 46 and the receiving groove enables the rotating rod 42 and the connecting rod 47 to be firmly connected together. When the connecting rod 47 moves, due to the limiting effect of the bolt 46, the rotating rod 42 will rotate with the movement of the connecting rod 47. At the same time, the cooperation of the bolt 46 in the receiving groove also ensures that the rotating rod 42 will not be separated from the connecting rod 47 during the rotation process, thereby ensuring that the force can be stably transmitted from the connecting rod 47 to the rotating rod 42, and then the fan blades 12 are driven to rotate through the connecting plate 41, thereby realizing the accurate opening and closing of the Venetian blinds.
[0036] In order to make the auxiliary rope 22 slide along the window frame 11 more smoothly, please refer to Figure 2 In a preferred embodiment, the top of the window frame 11 is rotatably connected to a guide wheel 24 , and the auxiliary rope 22 is overlapped on the top of the guide wheel 24 .
[0037] During use, when the Venetian blinds are opened and closed, as the main rope 21 moves, driving the auxiliary rope 22, the auxiliary rope 22 needs to change direction or move a certain distance within the window frame 11. Because the top of the window frame 11 is rotatably connected to a guide wheel 24, the auxiliary rope 22 overlaps the top of the guide wheel 24. When the auxiliary rope 22 is moved by a pulling or pushing force, the guide wheel 24 rotates accordingly. The function of the guide wheel 24 is to change the direction of the pulling force on the auxiliary rope 22, reducing the friction between the auxiliary rope 22 and the window frame 11, allowing the auxiliary rope 22 to move more smoothly, thereby more effectively transmitting the pulling or pushing force, driving the connector 4 and the fan blades 12 to move, and achieving smooth opening or closing of the Venetian blinds.
[0038] In order to make the disassembly and assembly of the roller 23 and the guide wheel 24 more convenient, please refer to Figure 2 In a preferred embodiment, a C-shaped ring is provided on the top of the window frame 11, the roller 23 is sleeved on the top of the C-shaped ring, and the guide wheel 24 is sleeved on the bottom of the C-shaped ring.
[0039] During use, the C-shaped ring is fixed to the top of the window frame 11, providing a mounting location for the roller 23 and guide wheel 24. The roller 23 is mounted on top of the C-shaped ring. When the main rope 21 is attached to the top of the roller 23 and moves, the roller 23 can rotate freely on the top of the C-shaped ring, reducing the resistance to the main rope 21's movement. The C-shaped ring also supports and limits the roller 23, ensuring that the roller 23 rotates stably in a fixed position and preventing it from shifting or falling off.
[0040] The guide wheel 24 is mounted on the bottom of the C-shaped ring. When the auxiliary rope 22 is attached to the top of the guide wheel 24 and moves, the guide wheel 24 can rotate freely on the bottom of the C-shaped ring. The C-shaped ring provides a stable support and a clear mounting position for the guide wheel 24, restricting its left and right movement and vertical movement. This ensures that the guide wheel 24 can accurately redirect the tension of the auxiliary rope 22, allowing the auxiliary rope 22 to smoothly transmit the tension and drive the blades 12 to open and close the blinds.
[0041] To limit the movement direction of the auxiliary rope 22, please refer to Figure 2 In a preferred embodiment, a guide ring 25 is provided at the top of the window frame 11 below the guide wheel 24 , and the auxiliary rope 22 is slidably inserted into the guide ring 25 .
[0042] During use, when the Venetian blinds are opened and closed, the auxiliary rope 22 slides through the guide ring 25 as it is pulled or pushed by the main rope 21. The guide ring 25 is fixed below the guide wheel 24 at the top of the window frame 11, restraining and guiding the auxiliary rope 22. As the auxiliary rope 22 moves, the guide ring 25 limits its swing range, forcing it to follow a specific path, preventing it from shifting, becoming entangled, or interfering with other components. This ensures that the auxiliary rope 22 can accurately and stably transmit the pulling or pushing force to the connector 4, thereby driving the blades 12 to rotate and achieving smooth and reliable opening and closing of the Venetian blinds.
[0043] To limit the rotation range of the fan blade 12, please refer to Figure 2 In a preferred embodiment, a limiting rod 13 is provided in the window frame 11 for limiting the rotation range of the fan blade 12.
[0044] During use, as the shutter's blades 12 rotate, a limiting rod 13 is fixedly mounted within the window frame 11. As the blades 12 rotate along the height of the window frame 11, they gradually approach the limiting rod 13. When the blades 12 come into contact with the limiting rod 13, the limiting rod 13 prevents further rotation, thereby limiting the range of rotation. This limiting action prevents the blades 12 from excessively rotating during opening and closing, ensuring the shutter can achieve the desired opening and closing angles. It also prevents damage or abnormal operation of the blades 12 due to excessive rotation.
[0045] To adjust the angle of the guide ring 25, refer to Figure 2 In a preferred embodiment, the guide ring 25 is rotatably connected to the top of the window frame 11 , and a nut 26 is rotatably connected to the guide ring 25 , and the nut 26 is used to tighten against the window frame 11 .
[0046] When in use, the guide ring 25 is rotatably connected to the top of the window frame 11, which enables the guide ring 25 to be rotated and adjusted to a certain angle relative to the window frame 11. During installation or use, if it is necessary to change the angle at which the auxiliary rope 22 passes through the guide ring 25 to obtain a more suitable tension transmission direction or a smoother movement path of the auxiliary rope 22, the guide ring 25 can be rotated to achieve this. The nut 26 rotatably connected to the guide ring 25 is used to tighten against the window frame 11. After adjusting the angle of the guide ring 25, rotate the nut 26 to bring it closer to the window frame 11 and tighten it. The friction generated between the nut 26 and the window frame 11 can fix the position of the guide ring 25 and prevent it from accidentally rotating during the movement of the auxiliary rope 22, thereby ensuring that the auxiliary rope 22 always slides stably in the set direction and angle, ensuring the accuracy and stability of the opening and closing action of the blinds.
[0047] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the air inlet of the blinds for farms of the utility model is described in detail: when the blinds need to be opened or closed, the driving assembly 3 on the window frame 11 is activated. The operation of the driving assembly 3 will drive the main rope 21 to move. Since the main rope 21 is slidably passed through the top of the window frame 11, the movement of the main rope 21 will pull or push the secondary rope 22 connected thereto. One end of the secondary rope 22 is connected to the main rope 21, and the other end is connected to the connector 4 that connects one side of the multiple blades 12. When the secondary rope 22 moves, it will drive the multiple blades 12 to move together through the connector 4. When the main rope 21 moves in one direction under the action of the driving assembly 3, the secondary rope 22 will pull the connector 4, causing the blades 12 to rotate along the height direction of the window frame 11, thereby realizing the opening or closing of the blinds.
[0048] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention.
