Description

Technical Field

[0001] This utility model relates to the technical field of window opening mechanisms, specifically a greenhouse facade lifting window opening mechanism. Background Technology

[0002] In greenhouse agriculture and horticulture, ventilation is a crucial element in regulating the temperature, humidity, and air quality inside greenhouses. Traditional greenhouse window opening methods often employ manual or simple mechanical structures, resulting in inconvenient operation, low automation, and poor sealing. For example, some greenhouses use top-opening or sliding side windows, but these methods often require complex mechanical structures and are easily affected by the external environment during opening and closing, leading to unstable ventilation.

[0003] Furthermore, existing window opening mechanisms are typically complex in structure, occupying space and increasing maintenance costs. Especially when frequent adjustments to ventilation volume are required, the response speed and flexibility of traditional mechanisms are insufficient to meet practical needs. Therefore, developing a simple, easy-to-operate, and highly automated greenhouse facade lifting window opening mechanism is of great significance for improving greenhouse ventilation efficiency and environmental control capabilities.

Two support rods are symmetrically arranged on the left and right. The fixed window frame is fixedly installed between the two support rods and located in the upper region. The movable window frame is connected to the support rods through the sliding guide assembly and is located in front of them. The lifting and displacement driving mechanism is connected to the movable window frame and is used to drive it to move up and down.

[0007] Based on the above scheme and as a preferred embodiment: the lifting displacement drive mechanism includes a rack, an integrated servo drive motor, vertical rods, horizontal rods, gears, and a transmission shaft. Two sets of racks are symmetrically arranged on both sides of the movable window frame, with the tooth surfaces of the racks facing forward.

Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0018] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a greenhouse facade lifting and opening window mechanism, including a fixed window frame 1, a movable window frame 2, a lifting and displacement driving mechanism 3, support rods 4, and a sliding guide assembly. The two support rods 4 are symmetrically arranged on the left and right. The fixed window frame 1 is fixedly installed between the two support rods 4 and located in the upper area. The movable window frame 2 is connected to the support rods 4 through the sliding guide assembly and is located in front of them. The lifting and displacement driving mechanism 3 is connected to the movable window frame 2 and is used to drive it to move up and down. When the movable window frame 2 is raised, the ventilation opening below the fixed window frame 1 can be exposed. The movable window frame 2 directly exposes the ventilation opening below the fixed window frame 1 through the lifting and lowering action. The ventilation area can be flexibly adjusted, and the ventilation volume can be quickly adjusted according to the environmental conditions inside and outside the greenhouse to meet the needs of different seasons and climate conditions.

[0019] In this embodiment, it is further preferred that the sliding guide assembly includes a slider 5 and a guide rail 6. Slider 5 is provided on the left and right sides of the movable window frame 2, and guide rail 6 is provided on the front side of the support rod 4. The guide rail 6 is perpendicular to the horizontal plane. The movable window frame 2 slides with the slider 5 and guide rail 6, making the lifting and lowering movement of the movable window frame 2 more stable. This avoids the jamming or offset problems caused by the complex structure of traditional window opening mechanisms. At the same time, the setting of the vertical guide rail 6 ensures the straightness of the window frame during the lifting and lowering process, improving the reliability of the mechanism.

[0020] In this embodiment, it is further preferred that the lifting displacement driving mechanism 3 includes a rack 31, an integrated servo drive motor 32, vertical rods 33, horizontal rods 34, a bearing 35, a gear 36, and a transmission shaft 37. Two sets of racks 31 are symmetrically arranged on both sides of the movable window frame 2, with the tooth surfaces of the racks 31 facing forward. The two vertical rods 33 are symmetrically arranged on both sides and located in front of the support rod 4. The two ends of the horizontal rod 34 are respectively connected to the vertical rods 33. The housing of the integrated servo drive motor 32 is fixedly connected to the horizontal rod 34. The output end of 32 is connected to the transmission shaft 37, which is arranged horizontally and has gears 36 connected to both ends. The gears 36 are coaxial with the transmission shaft 37 and mesh with the rack 31. When the gears 36 rotate, the rack 31 can move in the up and down direction. The meshing transmission between the rack 31 and the gears 36, combined with the integrated servo drive motor 32, realizes the precise lifting control of the movable window frame 2. The automated drive of the servo motor reduces the need for manual operation and improves the response speed and flexibility of greenhouse ventilation.

[0021] In this embodiment, it is further preferred that a bearing seat 35 is provided on the rear side of the vertical rod 33. The two side plates of the bearing seat 35 are located on the left and right sides of the gear 36. The end of the transmission shaft 37 passes through the through hole of the side plate of the bearing seat 35 and cooperates with the bearing therein. The design of the bearing seat 35 provides reliable support for the transmission shaft 37, ensuring that the gear 36 remains stable during rotation and avoiding the problem of poor meshing between the gear 36 and the rack 31 caused by the offset or shaking of the transmission shaft 37, thereby improving the overall stability of the mechanism.

[0022] In this embodiment, it is further preferred to include a limiting profile 7 and a side strip 8. The limiting profile 7 is installed on the top of the movable window frame 2 by bolts. The rear bent part of the limiting profile 7 is provided with a groove. The side strip 8 is provided with a hook 81 that cooperates with the groove at one end near the movable window frame 2, and a hemispherical protrusion 82 at the other end of the side strip 8. A small gap is left between the side strip 8 and the fixed window frame 1. The side strip 8 is preferably made of rubber. The limiting profile 7 is installed on the top of the movable window frame 2 by bolts. The installation process is simple and quick. The side strip 8 has good flexibility and plasticity. It is installed and adjusted by snap-fit, which is quick and convenient. It is also easy to replace and repair during maintenance. The installation of the side strip 8 reduces the gap between the movable window frame 2 and the fixed window frame 1 when the movable window frame 2 is in the lowered state, which improves the sealing of the greenhouse.

[0023] In this embodiment, it is further preferred that a plurality of reinforcing ribs 83 are provided below the edge strip 8. The reinforcing ribs can effectively increase the overall strength of the edge strip 8 and prevent it from being deformed or damaged by external forces such as wind and vibration during long-term use, thereby extending the service life of the edge strip 8.

[0024] It is worth noting that the integrated servo drive motor, gear rack and pinion and other technical features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent.
