Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and in particular to an easy-to-install flame-retardant and heat-insulating curtain. Background Technology

[0002] With the advent of high-molecular polymers such as polyvinyl chloride (PVC) and polyethylene (PE), plastic films have been widely used in agriculture, primarily for greenhouse construction to achieve early maturity and increased yields. The main materials used for covering greenhouse beds include ordinary polyethylene film, multi-functional long-life film with added anti-aging additives, straw mats, plastic sheets, non-woven fabrics, and shading curtains. Among these, shading curtains are composite plastic mesh fabrics available in several densities with varying shading rates. They are mainly used for sun and rain protection in summer and for insulation in winter. In modern agriculture and horticulture, shading curtains typically only provide shading or insulation, have a relatively simple structure, and are installed directly over the greenhouse, relying on weights for fixation. This results in poor insulation and susceptibility to punctures, affecting the overall insulation effect. To improve installation stability, additional supports and connecting components are needed. For example, Chinese patent document CN202021693353.1 discloses a solar greenhouse insulation curtain, including a curtain panel, a base frame, an energy converter, solar panels, sensors, a thermal camera, a top frame, electric heating tubes, a control box, a signal transmitter, a temperature detector, and an alarm. The base frame is located at the very bottom of the entire structure, electric heating tubes are evenly distributed inside the curtain panel, an alarm is located below the temperature detector, solar panels are installed on both sides of the top frame, and a sensor is located at the upper front of the thermal camera. This patent uses a base frame to support the entire structure and fixes the insulation curtain to the base frame from the edge. It is low-cost, sturdy, and durable. However, the curtain is usually installed on a greenhouse with a certain curvature, and the connection between the curtain and the center of the greenhouse is also very important.

[0003] Therefore, it is necessary for those skilled in the art to provide an easy-to-install flame-retardant and heat-insulating curtain and improve the stability of the connection between the curtain and the greenhouse. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-install flame-retardant and heat-insulating curtain to solve the technical problems of existing curtains having too many layers, making them difficult to fix, requiring heavy objects for fixation, resulting in poor heat insulation and easy puncture, which affects the heat insulation effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an easy-to-install flame-retardant heat-insulating curtain for installation on the top of a greenhouse, including a curtain body and multiple connectors detachably mounted on the curtain body. One end of the connector is fixedly mounted on the curtain body, and the other end of the connector is detachably connected to the top of the greenhouse. The curtain body includes, from the outside to the inside, an outer heat-insulating layer, a mixed fiber layer, a woven mesh, a fleece layer, and an inner heat-insulating layer. The outer heat-insulating layer, the mixed fiber layer, the woven mesh, the fleece layer, and the inner heat-insulating layer are stacked on top of each other in sequence. The inner heat-insulating layer abuts against the top of the greenhouse. The connector includes a fixed shaft, a rotating piece rotatably mounted on the fixed shaft, and a locking member detachably connected to the fixed shaft. The rotating piece abuts against the inner heat-insulating layer on the curtain body. One end of the locking member passes through the curtain body and is threaded into the fixed shaft, and the other end of the locking member abuts against the outer heat-insulating layer on the curtain body.

[0006] Furthermore, the rotating plate has two rotating plates that are rotatably disposed at both ends of the fixed shaft. The rotating plate has an abutment portion in the circumferential direction. The abutment portion can abut against the inner heat insulation layer on the curtain body. The abutment portion has an adhesive hole. The adhesive hole has a piercing member. Part of the piercing member is connected to the adhesive hole, and the other part of the piercing member extends into the curtain body.

[0007] Furthermore, the contact portion of the rotating plate is made of plastic.

[0008] Furthermore, the fixed shaft is provided with a connector and a mating hole on its circumferential side. The connector protrudes outward from the circumferential side of the fixed shaft and faces the greenhouse.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figure 1 , Figure 2This utility model provides an easy-to-install flame-retardant and heat-insulating curtain for installation on the top of a greenhouse, which is a common steel structure greenhouse with a crisscrossing steel structure. The easy-to-install flame-retardant and heat-insulating curtain includes a curtain body 10 and connectors 20 detachably mounted on the curtain body 10. One end of the connector 20 is fixed to the curtain body 10, and the other end is detachably connected to the top of the greenhouse. Multiple connectors 20 are provided and evenly distributed on the curtain body 10. The connectors 20 are connected to the steel structure of the greenhouse top using fasteners such as bolts and screws, thereby achieving stable installation of the curtain body 10.

[0023] Further, please refer to Figure 3 , Figure 4 The curtain body 10 has a composite structure. From the outside to the inside, the curtain body 10 includes an outer insulation layer 11, a mixed fiber layer 13, a woven mesh 14, a pile layer 15, and an inner insulation layer 12. The outer insulation layer 11, the mixed fiber layer 13, the woven mesh 14, the pile layer 15, and the inner insulation layer 12 are stacked on top of each other in sequence. The outer insulation layer 11 faces the outside atmosphere, and the inner insulation layer 12 abuts against the top of the greenhouse.

[0024] Specifically, the outer insulation layer 11 is woven from glass fiber, providing excellent waterproof and anti-aging properties. The mixed fiber layer 13 is made of nanofiber cotton. The unique three-dimensional structure of nanofibers gives them micropores, porous texture, and high air filtration capabilities, allowing them to store large amounts of air, providing high insulation, shortening the crop growth cycle, increasing crop yield, and improving economic benefits. Simultaneously, the small diameter of nanofibers effectively prevents moisture penetration, ensuring the material remains dry and fluffy even in humid areas and rainy / snowy weather conditions, significantly reducing the material's weight and achieving a soft, thin, and lightweight profile. This enhances ease of use and safety.

[0025] When in use, when cold air from the outside comes into contact with the curtain body 10, the outer insulation layer 11 can block or reflect the cold air. At the same time, the three-dimensional mesh structure composed of the outer insulation layer 11 and the mixed fiber layer 13 can form a relatively sealed space with still air filling the gaps, further preventing air exchange between the upper and lower surfaces of the curtain body 10, thus achieving preliminary heat insulation.

[0026] The woven mesh 14 is made of polyethylene, and the fleece layer 15 includes, but is not limited to, duck down. The fleece layer 15 is wound around the woven mesh 14, which ensures the stability and uniformity of the fleece layer 15 filling. The inner insulation layer 12 is made of non-woven fabric, which is used to enhance the strength of the fabric and give the inner insulation layer 12 excellent wear resistance. At the same time, the inner insulation layer 12 and the fleece layer 15 form a thick insulation structure, which effectively isolates the internal and external temperatures, preventing the internal temperature of the greenhouse from escaping. This ensures the effectiveness and stability of the greenhouse and achieves further insulation.

[0027] The curtain body 10 of this utility model is also provided with a stitching line (not shown in the figure). The stitching line is used to sew the curtain body 10, which has a composite structure, into a whole to ensure stability in use.

[0028] Further, please refer to Figure 4 , Figure 5 The connector 20 includes a fixed shaft 21, a rotating piece 22 rotatably mounted on the fixed shaft 21, and a locking member 23 detachably connected to the fixed shaft 21. The fixed shaft 21 has a cylindrical structure. Two rotating pieces 22 are rotatably mounted at both ends of the fixed shaft 21. Each rotating piece 22 has a contact portion 221 on its circumference, which abuts against the inner insulation layer 12 on the screen body 10. The contact portion 221 has an adhesive hole 222, and a piercing element (not shown) is provided within the adhesive hole 222. The piercing element includes, but is not limited to, a screw. Part of the piercing element is fitted into the adhesive hole 222, and the other part extends into the screen body 10. This securely connects the screen body 10 to the rotating piece 22.

[0029] In use, the abutment portion 221 is fixedly connected to the curtain body 10 via the piercing member, ensuring the stability of the connection and facilitating the subsequent installation of the curtain body 10 onto the top of the greenhouse. This invention provides a rotating plate 22 below the curtain body 10 to provide extensive support for it. The rotatable rotating plate 22 can adaptively adjust the contact angle according to the curvature of the curtain body 10 during installation, thereby ensuring stability during use.

[0030] In this embodiment, the contact portion 221 of the rotating plate 22 is made of plastic and has a certain elastic deformation to increase the contact area between the contact portion 221 and the curtain body 10.

[0031] In other embodiments, the abutment portion 221 is bonded to the curtain body 10 by adhesive, thereby reducing structural damage to the curtain body 10, ensuring the integrity of the curtain body 10, and improving installation efficiency.

[0032] Furthermore, the fixed shaft 21 is provided with a connector 25 and a mating hole 26 on its circumferential side. The connector 25 protrudes outward from the circumferential side of the fixed shaft 21 and faces the greenhouse. The connector 25 is provided with a threaded hole (not shown in the figure). In use, the connector 25 is fixedly connected to the steel structure of the greenhouse by fasteners such as bolts or screws to achieve a stable connection.

[0033] The mating hole 26 extends inward from the outer circumference of the fixed shaft 21 through the wall of the fixed shaft 21. One end of the locking member 23 can pass through the curtain body 10 and be threaded into the mating hole 26, while the other end of the locking member 23 abuts against the outer insulation layer 11 of the curtain body 10. The locking member 23 includes, but is not limited to, screws. In use, the locking member 23 is manually inserted into the curtain body 10 and connected to the fixed shaft 21, thereby stably connecting the curtain body 10 to the top of the greenhouse and ensuring installation stability. Compared with the prior art that relies on heavy objects for pressure, this utility model can effectively ensure the fit between the curtain body 10 and the top of the greenhouse, prevent the curtain body 10 from bulging or being pulled, improve the stability of use, and is suitable for various harsh weather conditions.

[0034] A sealing gasket 24 is fitted onto the locking member 23, and the sealing gasket 24 abuts against the outer insulation layer 11 of the curtain body 10. The sealing gasket 24 is made of PET high-temperature tape. In use, one end of the locking member 23 pierces the outer surface of the curtain body 10, and the sealing gasket 24 is used to bond to the outer insulation layer 11 to seal the piercing opening, thereby preventing rainwater from entering and improving the stability of the present invention.

[0035] The specific operation method of this utility model is as follows: the connector 20 is evenly distributed on the inner insulation layer 12 of the curtain body 10, and then the curtain body 10 is installed on the top of the greenhouse. The locking member 23 is manually inserted into the curtain body 10 and connected to the fixed shaft 21, thereby realizing the stable connection of the curtain body 10 to the top of the greenhouse.

[0036] This invention features multiple connectors 20 on the curtain body 10 to connect the curtain body 10 to the steel structure of the greenhouse roof. This effectively ensures a close fit between the curtain body 10 and the greenhouse roof, preventing localized bulging or stretching of the curtain body 10, improving stability, and making it suitable for various harsh weather conditions. Simultaneously, this invention includes rotatable flaps 22 on the connectors 20 to provide extensive support for the curtain body 10. The rotatable flaps 22 can adaptively adjust the contact angle according to the curvature of the curtain body 10 during installation, ensuring a closer fit between the curtain body 10 and the greenhouse roof, thus guaranteeing stability.
