Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural greenhouse technology, specifically a greenhouse with adjustable functions. Background Technology
[0002] Greenhouses, as a modern agricultural infrastructure, effectively overcome the limitations of natural climate on crop growth by artificially controlling the internal environment, enabling off-season cultivation and increased yields. Traditional greenhouses typically use a fixed structure with metal or plastic frames and covering materials. Their adjustment capabilities largely rely on additional independent components such as ventilation and shading, resulting in limited adjustment dimensions and insufficient overall coordination.
[0003] The drawback of existing technologies is that their supporting structures are mostly fixed and assembled using bolt connections. Once assembled, their overall length and dimensions are fixed, making it impossible to conveniently and reliably adjust the length according to changes in actual planting needs, size limitations of different plots, or to match specific specifications of greenhouse fabric. This inherent rigid structure results in a severe lack of flexibility in the application of greenhouses, making it difficult to adapt to diverse agricultural production needs. Therefore, we propose a greenhouse with adjustable functions. Summary of the Invention
[0004] The purpose of this invention is to provide a greenhouse with adjustable functions to address the aforementioned shortcomings of the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse with adjustable function, comprising a greenhouse cloth, and further comprising: The inner support frame is installed inside the canopy. The transmission assembly is located on one side of the inner bracket; The fastening assembly is located on both sides of the top of the canopy and the inner support. The inner support includes multiple sets of U-shaped rods. A hinge is connected between every two sets of adjacent U-shaped rods, and adjacent hinges are fixed by connecting rods. When the transmission assembly drives the hinges at the end of the inner support to extend laterally, the U-shaped rods extend synchronously under the drive of the hinges. The canopy is fastened to the inner support through the fastening assembly, and the canopy gradually unfolds under the extension of the inner support and resists the fastening assembly.
[0006] As a further description of the above technical solution: the hinge includes a grooved rod fixed to the side wall of the U-shaped rod, and a lifting rod is slidably installed between adjacent grooved rods. The lifting rod has a T-shaped slider integrally formed on the side facing the grooved rod, and the grooved rod is provided with a T-shaped groove for the T-shaped slider to slide up and down.
[0007] As a further description of the above technical solution: the hinge also includes a base block fixed to the side wall of the U-shaped rod, and a scissor bar is rotatably connected between the lifting rod and the base block.
[0008] As a further description of the above technical solution: the transmission assembly includes a first ring fixed to one side of the inner support, and a second ring is also slidably installed on one side of the inner support, the second ring being fixed to the adjacent lifting rod.
[0009] As a further description of the above technical solution: a drive rod is rotatably mounted on the first ring sleeve, the drive rod is threadedly connected to the second ring sleeve, and a screw tightening hole is provided at the top of the drive rod.
[0010] As a further description of the above technical solution: the fastening assembly includes a C-shaped plug bonded to the inner surface of the top of the tarpaulin, and insert rings are fixed on both sides of the top of the inner support. A spring is connected inside the insert ring, and a stop piece is fixed to one end of the spring and slidably installed inside the insert ring. When the C-shaped plug is inserted into the insert ring, the stop piece abuts against the C-shaped plug.
[0011] In the above technical solution, the greenhouse with adjustable function provided by this utility model has the following beneficial effects: This invention allows the operator to rotate a drive rod to drive the ring sleeve to slide linearly, thereby pushing the hinge at the end of the inner support to extend laterally. Then, a connecting rod drives all the hinges and U-shaped rods to extend synchronously, thus increasing the length of the inner support. During this process, the grooved rod moves with the U-shaped rod, allowing the lifting rod to slide within the grooved rod via a T-shaped slider to adapt to length changes. Simultaneously, the scissor rod rotates to maintain structural height and stability. As the inner support extends, the greenhouse fabric is tightened, and the spring force in the fastening assembly automatically presses the abutment against the insert, achieving reliable locking. The entire adjustment process can be achieved by rotating the drive rod in the opposite direction to retract the support. This design allows the greenhouse support structure to be adjusted in length according to actual needs, making its application more flexible. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0016] Please see Figures 1-6 This utility model provides a greenhouse technology solution with adjustable function: it includes a greenhouse cloth 1, and further includes: an inner support 2, disposed inside the greenhouse cloth 1; a transmission component 3, disposed on one side of the inner support 2; and a fastening component 4, disposed on both sides of the top of the greenhouse cloth 1 and the inner support 2. The inner support 2 includes multiple sets of U-shaped rods 21, and a hinge 22 is connected between every two sets of adjacent U-shaped rods 21. Adjacent hinges 22 are fixed together by connecting rods 23. When the transmission component 3 drives the hinges 22 at the end of the inner support 2 to extend laterally, the U-shaped rods 21 are connected to the hinges 22. Driven by the synchronous extension, the canopy 1 is fastened to the inner support 2 through the fastening assembly 4, and the canopy 1 gradually unfolds under the extension of the inner support 2 and generates a resistance to the fastening assembly 4; the inner support 2 is driven to extend laterally through the transmission assembly 3, and the inner support 2 achieves synchronous expansion through the linkage of its internal hinge 22 and U-shaped rod 21, thereby opening the canopy 1. The radial tension generated by the canopy 1 during the extension process finally acts on the fastening assembly 4, and the dynamic fastening of the connection part is achieved by using this resistance, ensuring the stability and reliability of the covering structure during the adjustment process.
[0017] In another embodiment of this utility model, preferably, the hinge 22 includes a grooved rod 24 fixed to the side wall of the U-shaped rod 21, and a lifting rod 25 slidably installed between adjacent grooved rods 24. The lifting rod 25 has a T-shaped slider 26 integrally formed on the side facing the grooved rod 24, and the grooved rod 24 is provided with a T-shaped groove for the T-shaped slider 26 to slide up and down. The hinge 22 also includes a base block 27 fixed to the side wall of the U-shaped rod 21, and a scissor rod 28 is rotatably connected between the lifting rod 25 and the base block 27. When the inner support 2 extends or retracts, the grooved rod 24 moves with the U-shaped rod 21, forcing the lifting rod 25 to slide up and down in the T-shaped groove of the grooved rod 24 through its T-shaped slider 26 to adapt to the length change. This process simultaneously drives the scissor rod 28 to rotate. Through the linkage between the lifting rod 25 and the scissor rod 28, the structural height is adjusted in a coordinated manner during the length adjustment process, and the overall stability is enhanced.
[0018] In another embodiment of this utility model, preferably, the transmission component 3 includes a first ring 31 fixed to one side of the inner support 2, and a second ring 32 slidably installed on one side of the inner support 2. The second ring 32 is fixed to the adjacent lifting rod 25. A drive rod 33 is rotatably installed on the first ring 31. The drive rod 33 is threadedly connected to the second ring 32, and a screw tightening hole is provided at the top of the drive rod 33. During operation, the drive rod 33 is rotated by a tool. Since the drive rod 33 is threadedly connected to the slidable second ring 32, and the first ring 31 is fixed, the rotational motion is converted into linear motion of the second ring 32 along the side of the inner support 2. The second ring 32 directly connects to and pushes the end structure of the inner support 2, thereby efficiently transmitting the driving force to the entire inner support 2 and initiating its extension or retraction process.
[0019] In another embodiment of this utility model, preferably, the fastening assembly 4 includes a U-shaped insert 41 bonded to the inner surface of the top of the canopy 1, and two insert rings 42 fixed on both sides of the top of the inner support 2. A spring 43 is connected inside the insert ring 42, and a stop piece 44 is fixed to one end of the spring 43 and slidably installed inside the insert ring 42. When the U-shaped insert 41 is inserted into the insert ring 42, the stop piece 44 abuts against the U-shaped insert 41. When the canopy 1 is installed, the U-shaped insert 41 is inserted into the insert ring 42. When the inner support 2 extends and opens the canopy 1, the tension generated by the canopy 1 causes the U-shaped insert 41 to tend to slide outward in the insert ring 42, thereby pressing the stop piece 44 and further compressing the spring 43. The reverse elastic force generated by the spring 43 makes the stop piece 44 always tightly abut against the U-shaped insert 41, forming an adaptive clamping force, realizing reliable locking of the canopy 1 and the inner support 2 in dynamic adjustment, and preventing loosening.
[0020] During operation, the operator first inserts a screwdriver or other tool into the screw hole at the top of the drive rod 33 and rotates it. The drive rod 33 rotates accordingly. Since the drive rod 33 and the second ring 32 are connected by a thread, while the first ring 31 is fixed, the rotational motion is converted into the second ring 32 sliding linearly along the side of the inner bracket 2. The movement of the ring 2 32 directly acts on the hinge 22 at the end of the inner support 2, pushing it to extend laterally. Since the adjacent hinges 22 are fixedly connected by the connecting rod 23, the lateral movement of a single hinge 22 will be transmitted to the entire array of hinges 22 through the connecting rod 23, causing all hinges 22 to extend laterally synchronously. Under the drive of the hinges 22, the multiple sets of U-shaped rods 21 connected to each hinge 22 also extend outward synchronously, thus increasing the length of the entire inner support 2. During the lateral extension of the inner support 2, the grooved rod 24 fixed to the side wall of the U-shaped rod 21 moves accordingly. The lifting rod 25 connecting the adjacent grooved rod 24 slides in the T-groove of the grooved rod 24 through the T-shaped slider 26 at its end to adapt to the change in the length of the support. At the same time, the scissor rod 28 rotatably connected between the lifting rod 25 and the base block 27 on the side wall of the U-shaped rod 21 changes angle. This linkage structure ensures that the longitudinal height and structural stability of the inner support 2 are maintained in tandem when it extends or retracts in the length direction. As the inner support 2 extends, the canopy 1, which is pre-fixed to both sides of the top of the inner support 2 by the fastening assembly 4, is gradually stretched open. The unfolding process of the canopy 1 generates radial tension on the inner support 2, and this tension is eventually transmitted to the fastening assembly 4. Specifically, by pre-inserting the U-shaped plug 41 into the insert ring 42 at the top of the inner support 2, the canopy 1 generates a resisting force on the insert ring 42 when it unfolds. This force acts on the abutment 44 inside the insert ring 42 and compresses the spring 43 inside it. The reverse elastic force provided by the spring 43 keeps the abutment 44 in close contact with the U-shaped plug 41, thereby achieving reliable locking between the canopy 1 and the inner support 2 during dynamic adjustment and preventing the canopy 1 from loosening or shifting.
[0021] In summary, the transmission component 3 drives the inner support 2 to extend laterally, which in turn causes the canopy cloth 1 to tighten and unfold. Finally, the fastening component 4 achieves a stable fastening under the action of spring force, completing the adjustment of the greenhouse from the closed state to the unfolded covered state. Reverse rotation of the drive rod 33 can make each component move in the opposite order, realizing the closure of the greenhouse.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
