Description

Technical Field

[0001] This utility model relates to the field of greenhouse window opening technology, specifically a greenhouse ventilation window opening structure. Background Technology

[0002] Greenhouses break the limitations of natural seasons on planting, allowing crops that could only be grown in specific seasons to be produced in other seasons. Greenhouses effectively insulate against the effects of low external temperatures, creating suitable growing temperatures for crops during cold seasons. However, long-term sealing of greenhouses can lead to an imbalance in the internal environment, severely affecting crop growth. Therefore, greenhouses must be ventilated by opening windows.

[0003] In existing technologies, the automatic opening structure of greenhouse side windows often adopts a "curtain motor drive + gear and rack transmission" technical solution: the output shaft of the curtain motor is fixedly connected to the rotating shaft, and multiple gears are fixedly mounted on the outer circumference of the rotating shaft. Each gear meshes with a set of racks for transmission. The other end of the rack is fixed to the side window through a connector. When the motor drives the rotating shaft to rotate, the gear drives the rack to move linearly, thereby pulling the side window to rotate and open for greenhouse ventilation. However, in actual use, since the gears and racks are usually pre-installed and meshed, and each set of racks needs to be connected to the corresponding side window, it is necessary to coordinate the positional accuracy and synchronization of multiple sets of gears and racks at the same time. During installation, problems such as misalignment of the rack and gear meshing and deviation of the connection between the side window and the rack are prone to occur. It is also inconvenient to replace damaged racks. Summary of the Invention

[0004] The purpose of this invention is to provide a greenhouse ventilation window structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A greenhouse ventilation window structure includes an upright and a support rod. An extension plate is fixedly installed on the front of the support rod, and a curtain-pulling motor is fixedly installed on the front of the upright. A rotating shaft is fixedly installed at the output end of the curtain-pulling motor. The rotating shaft and the extension plate are rotatably mounted. A window opening mechanism is provided outside the rotating shaft, and a positioning mechanism is provided outside the window opening mechanism.

[0007] Preferably, the window opening mechanism includes a connecting cylinder, which is fixedly installed outside the rotating shaft. A gear is fixedly installed outside the connecting cylinder, and a side plate is rotatably installed outside the connecting cylinder. A rack meshes with the gear, and the rack is slidably installed inside the side plate. A connector is rotatably installed at one end of the rack. An arc-shaped cover is slidably installed outside the side plate, and a connecting plate is fixedly installed on the inner wall of the arc-shaped cover. The connecting plate is slidably installed on the outer side of the side plate, and a first extension block is fixedly installed on the outer side of the connecting plate to facilitate the opening and closing of the greenhouse window.

[0008] Preferably, two side plates are provided, and the two side plates are rotatably mounted on the outside of the connecting cylinder to facilitate the surrounding of the gear and rack.

[0009] Preferably, the positioning mechanism includes a support plate, which is movably mounted on the bottom of the side plate. A vertical plate is fixedly mounted on the top of the support plate, and a support column is rotatably mounted inside the vertical plate. The support column contacts the bottom of the rack. A second extension block is fixedly mounted on the outside of the support plate, and a vertical column is fixedly mounted on the top of the second extension block. A stud is fixedly mounted on the top of the vertical column, and a nut is installed on the external thread of the stud, which facilitates the support and limiting of the rack and allows for quick assembly and disassembly of the rack.

[0010] Preferably, a through hole is provided inside the first extension block at the position corresponding to the column, and the column is slidably installed in the through hole to facilitate the positioning of the column and the support plate.

[0011] Compared with the prior art, the present invention provides a greenhouse ventilation window structure, which has the following beneficial effects:

[0012] This utility model features a window opening mechanism. During use, the connecting cylinder allows the side plate to rotate with the shaft, facilitating the movement of the rack. With the cooperation of the connecting parts, the side window of the greenhouse can be rotated and opened for ventilation. The arc-shaped cover and connecting plate cover the connecting cylinder and shield the gears, ensuring their cleanliness. The first extension block facilitates the subsequent positioning of the arc-shaped cover.

[0013] This utility model, through its positioning mechanism, facilitates the positioning of the support plate during use. The column, in conjunction with the first extension block, enables the positioning of the support plate and the arc-shaped cover. The stud and nut facilitate the limiting of the support plate and the arc-shaped cover. The support column also facilitates the support and limiting of the rack. This allows for easier connection of the rack to the side window before installation, simplifying the rack installation process and preventing problems such as misalignment of the gear and rack, and deviation in the connection between the side window and the rack. Furthermore, it facilitates quick disassembly and reassembly of damaged racks. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-3 This utility model provides a technical solution: a greenhouse ventilation window structure, including a vertical pole 1 and a support pole 2. Several support poles 2 are provided, and the support poles 2 are equidistantly arranged on both sides of the vertical pole 1. The vertical pole 1 and the support poles 2 are both fixedly installed on the ground outside the greenhouse. An extension plate 3 is fixedly installed on the front of the support pole 2. A curtain-pulling motor 4 is fixedly installed on the front of the vertical pole 1. A rotating shaft 5 is fixedly installed at the output end of the curtain-pulling motor 4. The rotating shaft 5 and the extension plate 3 are rotatably installed. A window opening mechanism 6 is provided outside the rotating shaft 5. Multiple sets of window opening mechanisms 6 are provided. The number of window opening mechanisms 6 corresponds to the number of side windows of the greenhouse. A positioning mechanism 7 is provided outside the window opening mechanism 6.

[0022] Furthermore, the window opening mechanism 6 includes a connecting cylinder 601, which is fixedly installed on the outside of the rotating shaft 5. A gear 602 is fixedly installed on the outside of the connecting cylinder 601, and a side plate 603 is rotatably installed on the outside of the connecting cylinder 601. A rack 604 meshes with the outside of the gear 602, and the rack 604 is slidably installed on the inside of the side plate 603. A connector 605 is rotatably installed at one end of the rack 604. An arc-shaped cover 606 is slidably installed on the outside of the side plate 603, and a connecting plate 607 is fixedly installed on the inner wall of the arc-shaped cover 606. The connecting plate 607 is slidably installed on the outside of the side plate 603. A first extension block 608 is fixedly installed on the outer side of the connecting plate 607. The connecting cylinder 601 facilitates the rotation of the side plate 603 with the rotating shaft 5, thereby facilitating the movement of the rack 604. With the cooperation of the connecting piece 605, the side window of the greenhouse can be rotated and opened for ventilation. The arc-shaped cover 606 and the connecting plate 607 can surround the connecting cylinder 601 and cover the gear 602, ensuring the cleanliness of the gear 602. With the cooperation of the first extension block 608, the arc-shaped cover 606 can be limited in position later.

[0023] Furthermore, two side plates 603 are provided, and the two side plates 603 are rotatably mounted on the outside of the connecting cylinder 601 to facilitate the surrounding of the gear 602 and the rack 604.

[0024] Please see Figure 4Furthermore, in conjunction with the embodiments, the positioning mechanism 7 includes a support plate 701, which is movably mounted on the bottom of the side plate 603. A vertical plate 702 is fixedly mounted on the top of the support plate 701. A support column 703 is rotatably mounted inside the vertical plate 702. Two support columns 703 are provided, symmetrically arranged on the top of the support plate 701 to facilitate stable support of the rack 604. The support column 703 contacts the bottom of the rack 604. A second extension block 704 is fixedly mounted on the outer side of the support plate 701. A column 705 is fixedly mounted on the top of the second extension block 704. A stud 706 is fixedly mounted on the top of the column 705. The diameter of the stud 706 is slightly smaller than the diameter of the column 705. The external thread of the stud 706 is fitted with a nut 707. With the cooperation of the first extension block 608, the support plate 701 is easily positioned by the set column 705. With the cooperation of the stud 706 and the nut 707, the support plate 701 and the arc-shaped cover 606 are easily limited. With the cooperation of the support column 703, the rack 604 is easily supported and limited. This makes it easy to connect the rack 604 to the side window first, and then install the rack 604. This simplifies the installation steps of the rack 604 and avoids problems such as misalignment of gear 602 and rack 604, and connection deviation between the side window and rack 604 during the installation process. It also makes it easy to quickly disassemble and reassemble damaged rack 604.

[0025] Furthermore, the first extension block 608 has a through hole at the position corresponding to the column 705, and the column 705 is slidably installed in the through hole, which facilitates the positioning of the column 705 and the support plate 701.

[0026] Working principle: In actual operation, when this device is used, the connector 605 is connected to the greenhouse side window, and the rack 604 is rotated to make it contact the gear 602. By adjusting the angle of the rotating shaft 5, the gear 602 and the rack 604 are meshed, thereby completing the positioning of the gear 602. This facilitates the subsequent positioning and meshing of multiple gears 602. The arc-shaped cover 606 and the connecting plate 607 are placed over the connecting cylinder 601, and the column 705 passes through... The first extension block 608 threadedly installs the nut 707 onto the outside of the stud 706, thereby limiting the support plate 701 and the arc-shaped cover 606, and causing the support column 703 to contact the rack 604, thus limiting the rack 604. When greenhouse ventilation is required, the curtain-pulling motor 4 is started, causing the rotating shaft 5 to rotate, which in turn causes the gear 602 to rotate, causing the rack 604 to move in the direction of the gear 602, thereby rotating and opening the greenhouse side window to ventilate the greenhouse.
