Description

Technical Field

[0001] This utility model relates to the field of greenhouse installation technology, specifically a connection structure between a greenhouse longitudinal pipe and an arch pipe. Background Technology

[0002] Early agricultural production was mostly carried out in the open air, and the growth of crops depended entirely on natural environmental conditions. With the advancement of agricultural technology, people began to use simple protective measures, usually ropes or simple wires for binding.

[0003] A search of Chinese utility model patent (publication number CN219679339U) reveals a connection and installation structure for longitudinal pipes and arch pipes in greenhouses, including longitudinal pipes, arch pipes, connecting frames, clamping rods, baffles, handles, slots, connecting pieces, U-shaped clamps, and nuts. This technical solution improves the connection strength between the greenhouse longitudinal pipes and arch pipes; increases the distance between the longitudinal pipes and the film, avoids friction between the film and the longitudinal pipes, and effectively extends the service life of the film.

[0004] However, through exploration, the inventors have discovered that this technical solution still has at least the following defects:

[0005] The existing connection structure cannot adjust the spacing between the longitudinal pipe and the arch pipe. When dealing with pipes of different specifications, installation difficulties may occur, affecting the overall structural stability of the greenhouse. Utility Model Content

[0006] The present invention aims to provide a connection structure between the longitudinal pipe and the arch pipe of a greenhouse to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A connection structure for a greenhouse longitudinal pipe and an arched pipe, characterized in that: it includes a longitudinal pipe and an arched pipe, the arched pipe is fitted with a connecting frame, the connecting frame is connected to a fixing plate, the fixing plate is slidably connected to a sliding plate, the sliding plate is connected to a connecting piece, the longitudinal pipe is fitted with a U-bolt, the U-bolt is movably connected to the connecting piece, the U-bolt is threaded with a nut, the sliding plate has a groove, the inner wall of the groove is connected to a spring, the spring is connected to a fixing button, the fixing button is slidably connected to the groove, the fixing plate has a fixing hole, and the fixing button cooperates with the fixing hole;

[0009] The connecting frame is connected to a support structure, which is used to support the lower part of the arch tube.

[0010] Preferably, the support structure includes a snap-fit ​​rod, the connecting frame has a slot, the snap-fit ​​rod passes through the slot, the snap-fit ​​rod is connected to a baffle, and the baffle cooperates with the slot.

[0011] Preferably, the locking rod is connected to a handle.

[0012] Preferably, the upper part of the connecting frame has a U-shaped structure and is wrapped around the arched tube.

[0013] Preferably, the connecting frame is connected to a rubber pad.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0015] (1) This solution, through the use of sliding grooves, springs, fixing buttons, and fixing holes, makes the distance between the longitudinal pipe and the arch pipe adjustable, easily adapting to different specifications of longitudinal and arch pipes, greatly improving the convenience of installation and the overall structural stability of the greenhouse. Furthermore, this adjustable structure allows construction workers to quickly change the distance between the longitudinal pipe and the arch pipe according to actual conditions, avoiding the hassle of re-cutting pipes or replacing connecting parts due to unsuitable spacing, effectively improving construction efficiency. Simultaneously, it increases the distance between the longitudinal pipe and the film, preventing friction between the film and the longitudinal pipe and effectively extending the service life of the film.

[0016] (2) By setting up a support structure to support the lower part of the arch pipe, the overall structural shape of the greenhouse can be kept stable. In windy weather, it is not easy to shift or sway, thus greatly improving the wind resistance of the greenhouse and reducing the risk of the greenhouse collapsing or being damaged by wind disasters. This creates a more favorable growing environment for crops, which is conducive to improving crop yield and quality.

[0017] (3) By setting handles, it is easier for staff to operate, enabling them to more accurately control the position and angle of the parts, quickly complete the installation steps, significantly reduce installation time, and improve the efficiency of the entire greenhouse construction work.

[0018] (4) By setting up a U-shaped connecting frame, the arch pipe is covered and the contact area for stress is increased. The force can be evenly distributed to the arch pipe and longitudinal pipe through the connecting frame, giving full play to the load-bearing potential of the entire structure. This makes it less likely for the connecting frame and the arch pipe to loosen or separate, effectively ensuring the stability of the overall greenhouse structure. It can also prevent large-scale torsion between the arch pipe and the longitudinal pipe, avoiding damage to the connecting structure or overall deformation of the greenhouse due to excessive torsion, thereby maintaining the integrity and stability of the greenhouse structure, reducing the frequency of maintenance and replacement of parts, and lowering agricultural production costs.

[0019] (5) By setting rubber pads, a buffering effect can be achieved, reducing the impact force caused by violent shaking, lowering the risk of structural damage, and extending the service life of the greenhouse structure. In addition, a soft isolation layer is formed between the arch pipe and the connecting frame, avoiding direct friction between the two, protecting the surface of the arch pipe, maintaining its good anti-corrosion and other properties, and thus ensuring the structural strength and service life of the arch pipe.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0025] A connection structure for a greenhouse longitudinal pipe and an arched pipe includes a longitudinal pipe 8 and an arched pipe 1. The longitudinal pipe 8 is positioned below the arched pipe 1, and the arched pipe 1 intersects the longitudinal pipe 8 perpendicularly in the plane. A connecting frame 2 is fitted onto the outer wall of the arched pipe 1. Two fixing plates 4 are symmetrically connected to the lower part of the connecting frame 2. The two fixing plates 4 extend obliquely towards the longitudinal pipe 8 to increase the load-bearing strength and area of ​​the lower part of the connecting frame 2. The lower parts of the two connecting plates expand and open towards the longitudinal pipe 8, forming a triangle. The triangular structure has higher load-bearing reliability than existing installation structures and also higher than rectangular structures. Sliding plates 6 are slidably connected to the inner walls of the two fixing plates 4, and connecting pieces 7 are connected to the bottom of the two sliding plates 6. U-bolts 10 are fitted onto the outer wall of the longitudinal pipe 8, and the U-bolts 10 connect to the connecting pieces... 7. Movable connection: U-bolt 10 is threaded with nut 9, which is used to fix it to connecting piece 7. Sliding plate 6 has two grooves 16, and springs 15 are connected to the inner walls of the two grooves 16 respectively. Springs 15 provide support and reset. The other end of spring 15 is connected to a fixing button 5, which is slidably connected to the groove 16. Fixing plate 4 has several fixing holes 14, and fixing buttons 5 cooperate with fixing holes 14. By pressing two fixing buttons 5 simultaneously, springs 15 are compressed, pulling sliding plate 6 for adjustment. Finally, springs 15 drive fixing buttons 5 into fixing holes 14, thus completing the adjustment. This allows workers to quickly change the distance between longitudinal tube 8 and arch tube 1. Connecting frame 2 is connected to a support structure, which supports the lower part of arch tube 1. The supporting structure includes a snap-fit ​​rod 12. A connecting frame 2 has a slot 13 through which the snap-fit ​​rod 12 passes. A baffle 11 is connected to the snap-fit ​​rod 12; the baffle 11 is smaller than the slot 13 and can pass through it. The baffle 11 and the slot 13 cooperate to align and insert the baffle 11 until it extends out of the connecting frame 2, then rotate 90 degrees to fix the snap-fit ​​rod 12. A handle 3 is connected to the other end of the snap-fit ​​rod 12 away from the baffle 11. The upper part of the connecting frame 2 has a U-shaped structure and is fitted over the arch tube 1. The upper part of the connecting frame 2 has a certain width along the axial direction of the arch tube 1, which allows for better coverage of the arch tube 1 and increases the contact area between the connecting frame 2 and the arch tube 1, improving the connection strength. When the arch tube 1 and the longitudinal tube 8 are subjected to external forces and twist, the relative displacement can be reduced. A rubber pad is connected to one end of the connecting frame 2 near the arch tube 1, forming a soft isolation layer between the connecting frame 2 and the arch tube 1, thus avoiding direct friction between the two.

[0026] The specific implementation process is as follows:

[0027] By pressing the two fixed buttons 5 simultaneously, the spring 15 is compressed, and the sliding plate 6 is pulled for adjustment. Finally, the spring 15 drives the fixed button 5 to lock into the fixed hole 14, thus completing the adjustment and quickly changing the distance between the longitudinal tube 8 and the arch tube 1 to accommodate different specifications of longitudinal tube 8 and arch tube 1.

[0028] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
