Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a three-way connector for the construction of agricultural greenhouses. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through, retains or heats the soil, and is used for plant cultivation or animal breeding. Current greenhouse technology typically consists of a frame or support structure made of several pipes, along with a plastic film fixed to the outside of the frame or support. Connectors are crucial structural components that connect the various pipes during the construction of the frame or support.

[0003] Based on the above, the inventors have discovered the following problems: Current three-way connectors are generally integrally molded, and the positions of their three connection ends are not adjustable. Greenhouse construction has various requirements for frame angles and pipe connection positions due to terrain, crops, lighting, etc. The connection end positions of integrally molded three-way connectors are fixed and cannot be adjusted, making it difficult to adapt to pipes with different directions and angles. When building irregularly shaped greenhouses such as arched roofs or sloping side walls, it is impossible to adjust the angle and position of the connector connection end relative to the pipe, thereby reducing the practicality of the three-way connector.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a three-way joint for the construction of agricultural greenhouses, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a three-way connector for the construction of agricultural greenhouses, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A three-way connector for constructing agricultural greenhouses includes a first steering assembly and a pair of second steering assemblies. The pair of second steering assemblies are respectively disposed on opposite sides of the outside of the first steering assembly. The first steering assembly is used to adjust the angle of a first connecting pipe, and the second steering assemblies are used to adjust the angle of a second connecting pipe. The first steering assembly includes a base with an installation groove on its upper surface. A rotating sleeve is rotatably connected within the installation groove. The outer wall of the rotating sleeve is fitted with a first connecting pipe. Each pair of second steering assemblies includes a first stud and a second universal joint fork. The first universal joint fork is fitted with a first universal joint fork at its end away from the base. The inner cavity of the first universal joint fork is connected to the inner cavity of the second universal joint fork via a universal cross shaft. The second universal joint fork has a connecting seat on its side away from the first universal joint fork, and a second connecting pipe is fitted on one side of the connecting seat.

[0008] Furthermore, each end of the base has a first screw hole, a pair of first studs are respectively disposed inside the first screw hole, and the pair of first studs are threadedly connected to the pair of first screw holes. The cross-section of the base is I-shaped, and the inner wall of the rotating sleeve is rotatably engaged with the outer wall of the mounting groove.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the use of the first screw hole and the first stud facilitates the quick assembly and disassembly of the first steering component and the second steering component. At the greenhouse construction site, workers do not need complicated tools and can complete the assembly by simply screwing the threads together, which greatly shortens the construction time. If maintenance or replacement of parts is required later, it can also be quickly disassembled, reducing the difficulty and time cost of maintenance. At the same time, the use of the first universal joint fork, the universal cross shaft and the second universal joint fork can flexibly adapt to the pipe connection of different spatial angles of the greenhouse, meet the frame construction requirements of the greenhouse with irregular structure and different orientation. Since the cross-section of the base is I-shaped, it prevents the rotating sleeve from falling off the base or from being displaced. At the same time, since the outer wall of the mounting groove and the inner wall of the rotating sleeve rotate and engage, it is convenient to rotate the rotating sleeve to adjust the position of the first connecting pipe.

[0010] Furthermore, the connecting seat has a second screw hole inside, and a second stud is threaded into the second screw hole. One end of the second stud is fixedly connected to the side of the second universal joint fork near the connecting seat.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation between the second screw hole and the second stud, it is easy to quickly disassemble and assemble the second connecting pipe and the second universal joint fork. On the greenhouse construction site, it is easy to replace the second connecting pipe according to the different diameters of the greenhouse connecting pipe fittings, so that the second connecting pipe matches the greenhouse connecting pipe fittings.

[0012] Furthermore, a second connector is installed at the end of the second connecting pipe away from the second universal joint fork. The inner and outer walls of the second connecting pipe are provided with several threads. A second locking nut is threaded onto the outer wall of the second connecting pipe. The outer wall of the second connector is provided with several threads, and the second connector is a cylindrical structure with an elastic closing function.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since the inner wall of the second connecting pipe is threaded, when the threaded end of the greenhouse body connecting pipe enters the second connecting pipe through the second connector, the greenhouse body connecting pipe is tightened under the action of thread engagement, so that the greenhouse body connecting pipe and the second connecting pipe are connected first. Then, the second locking nut is tightened, and the second locking nut is used to squeeze the second connector end, causing it to elastically contract and tightly hold the greenhouse body connecting pipe for secondary connection. The elastic closing clamping force combined with the mechanical locking of the thread can provide stable and reliable axial and radial constraint forces, ensuring that the connection is firm and maintaining the integrity of the greenhouse frame.

[0014] Furthermore, the first connecting pipe has a first connector installed at the end away from the rotating sleeve. The inner and outer walls of the first connecting pipe are provided with several threads. The outer wall of the first connecting pipe is threaded with a first locking nut. The outer wall of the first connector is provided with several threads, and the first connector is a cylindrical structure with an elastic closing function.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since the inner wall of the first connecting pipe is threaded, when the threaded end of the greenhouse body connecting pipe enters the first connecting pipe through the first connector, the greenhouse body connecting pipe is tightened under the action of thread engagement, so that the greenhouse body connecting pipe is connected to the first connecting pipe first. Then, the first locking nut is tightened, and the first locking nut squeezes the first connector end to make it elastically contract, tightly holding the greenhouse body connecting pipe for secondary connection. The elastic contraction clamping force combined with the mechanical locking of the thread can provide stable and reliable axial and radial constraint forces, ensuring that the connection is firm and maintaining the integrity of the greenhouse frame.

[0016] Furthermore, the exterior of the first universal joint fork, the universal cross shaft, and the second universal joint fork are all provided with an anti-corrosion coating, which is made of epoxy resin.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by providing an anti-corrosion coating on the exterior of the first universal joint fork, the universal cross shaft, and the second universal joint fork, and the anti-corrosion coating being made of epoxy resin, the epoxy resin coating has good chemical stability and can form a dense protective film on the metal surface of the first universal joint fork, the universal cross shaft, and the second universal joint fork, blocking water vapor, moisture, and slight chemical substances in the agricultural greenhouse environment from contacting the metal, extending the service life of the universal joint components, and ensuring the structural stability of the first universal joint fork, the universal cross shaft, and the second universal joint fork.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the three-way joint used in the construction of agricultural greenhouse greenhouses, by setting the first steering component, the position of the rotating sleeve outside the base is adjusted, and then the position of the first connecting pipe is adjusted. By setting the second steering component, the second connecting pipe is adjusted in position under the combined use of the first universal joint fork, the universal cross shaft and the second universal joint fork, so as to be able to flexibly adapt to the connection of pipe fittings at different spatial angles in the greenhouse and meet the requirements for building frames with special-shaped structures and different orientations of the shed body.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4This utility model provides a technical solution: a three-way connector for constructing agricultural greenhouses, comprising a first steering assembly 1 and a pair of second steering assemblies 2. The pair of second steering assemblies 2 are respectively disposed on opposite sides of the outside of the first steering assembly 1. The first steering assembly 1 is used to adjust the angle of the first connecting pipe 14, and the second steering assemblies 2 are used to adjust the angle of the second connecting pipe 27. The first steering assembly 1 includes a base 11, on which an installation groove 12 is provided. A rotating sleeve 13 is rotatably connected in the installation groove 12. The first connecting pipe 14 is installed on the outer wall of the rotating sleeve 13. Each pair of second steering assemblies 2 includes a first stud 21 and a second universal joint fork 24. The first stud 21 is equipped with a first universal joint fork at the end away from the base 11. The inner cavity of the first universal joint fork 22 is connected to the inner cavity of the second universal joint fork 24 via the universal cross shaft 23. The second universal joint fork 24 has a connecting seat 26 on the side away from the first universal joint fork 22. A second connecting pipe 27 is installed on one side of the connecting seat 26. By setting the first steering component 1, the position of the outer rotating sleeve 13 of the base 11 is adjusted, thereby realizing the position adjustment of the first connecting pipe 14. By setting the second steering component 2, the position of the second connecting pipe 27 is adjusted under the cooperation of the first universal joint fork 22, the universal cross shaft 23 and the second universal joint fork 24, so as to flexibly adapt to the pipe connection of different spatial angles of the greenhouse and meet the frame construction requirements of the greenhouse with irregular structure and different orientation.

[0026] 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.

[0027] Please see Figures 1-4This utility model provides a technical solution: First screw holes 17 are provided inside both ends of the base 11. A pair of first studs 21 are respectively disposed inside the first screw holes 17, and the pair of first studs 21 are threadedly connected to the pair of first screw holes 17. The cross-section of the base 11 is I-shaped, and the inner wall of the rotating sleeve 13 is rotatably engaged with the outer wall of the mounting groove 12. A second screw hole is provided inside the connecting seat 26, and a second stud 25 is threadedly connected inside the second screw hole. One end of the second stud 25 is fixedly connected to the side of the second universal joint fork 24 near the connecting seat 26, through the first screw hole. The use of 17 and the first stud 21 facilitates the quick assembly and disassembly of the first steering assembly 1 and the second steering assembly 2. At the greenhouse construction site, workers can complete the assembly by simply screwing the threads together without complicated tools, which greatly shortens the construction time. If maintenance or replacement of parts is required later, it can also be quickly disassembled, reducing the difficulty and time cost of maintenance. Since the cross-section of the base 11 is I-shaped, it prevents the rotating sleeve 13 from falling off the base 11 or from being displaced. At the same time, since the outer wall of the mounting groove 12 and the inner wall of the rotating sleeve 13 rotate and engage, it is easy to rotate the rotating sleeve 13 to adjust the position of the first connecting pipe 14.

[0028] 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.

[0029] Please see Figures 1-4This utility model provides a technical solution: a second connector 28 is installed on the end of the second connecting pipe 27 away from the second universal joint fork 24. The inner and outer walls of the second connecting pipe 27 are provided with several threads. A second locking nut 29 is threaded onto the outer wall of the second connecting pipe 27. The outer wall of the second connector 28 is provided with several threads, and the second connector 28 is a cylindrical structure with an elastic closing function. A first connector 15 is installed on the end of the first connecting pipe 14 away from the rotating sleeve 13. The inner and outer walls of the first connecting pipe 14 are provided with several threads. The outer wall of the first connecting pipe 14 is threaded... The first connector 15 is connected to a first locking nut 16. The outer wall of the first connector 15 has several threads, and the first connector 15 is a cylindrical structure with an elastic closing function. The outer surfaces of the first universal joint fork 22, the universal cross shaft 23, and the second universal joint fork 24 are all coated with an anti-corrosion coating made of epoxy resin. Because the inner wall of the second connecting pipe 27 is threaded, when the threaded end of the canopy connecting pipe passes through the second connector 28 and enters the second connecting pipe 27, the canopy connecting pipe is tightened through the thread engagement, thus connecting the canopy connecting pipe to the second connecting pipe 27. Then, tighten the second locking nut 29. The second locking nut 29 compresses the second connector 28, causing it to elastically contract and tightly grip the shed body connecting pipe, thus performing a secondary connection. Since the inner wall of the first connecting pipe 14 is threaded, when the threaded end of the shed body connecting pipe passes through the first connector 15 and enters the first connecting pipe 14, the threaded engagement tightens the shed body connecting pipe, connecting it to the first connecting pipe 14. Then, tighten the first locking nut 16, using the first locking nut 16 to compress the first connector 15, causing it to elastically contract. The elastic contraction tightly grips the connecting pipes of the greenhouse body for secondary connection. The clamping force of the elastic contraction, combined with the mechanical locking of the threads, provides stable and reliable axial and radial restraint forces, ensuring a firm connection and maintaining the integrity of the greenhouse frame. The first universal joint fork 22, universal cross shaft 23, and second universal joint fork 24 are all equipped with anti-corrosion coatings made of epoxy resin. The epoxy resin coating has good chemical stability and can form a dense protective film on the metal surfaces of the first universal joint fork 22, universal cross shaft 23, and second universal joint fork 24, extending the service life of the universal joint components.

[0030] Specifically, the working principle of this three-way joint used for agricultural greenhouse construction is as follows: During use, at the greenhouse construction site, workers do not need complex tools; they can assemble the first steering component 1 and the second steering component 2 simply by screwing in the threads. Adjusting the position of the outer rotating sleeve 13 of the base 11 allows for the adjustment of the position of the first connecting pipe 14. When the threaded end of the greenhouse body connecting pipe passes through the first connector 15 and enters the first connecting pipe 14, the connecting pipe is tightened through the thread engagement, connecting it to the first connecting pipe 14. Then, the first locking nut 16 is tightened, causing the first connector 15 to elastically contract and tightly grip the greenhouse body connecting pipe for a secondary connection. This is achieved at the first universal joint fork 22 and the universal joint... The use of the cross shaft 23 and the second universal joint fork 24 allows the second connecting pipe 27 to be adjusted according to the needs of pipe connection at different spatial angles of the greenhouse, the irregular structure of the greenhouse body, and the frame construction of different orientations. When the threaded end of the greenhouse body connecting pipe passes through the second connector 28 and enters the second connecting pipe 27, the greenhouse body connecting pipe is tightened by the thread engagement, so that the greenhouse body connecting pipe and the second connecting pipe 27 are connected first. Then, the second locking nut 29 is tightened. The second locking nut 29 squeezes the second connector 28 port to make it elastically contract, tightly holding the greenhouse body connecting pipe for secondary connection. Due to the clamping force of the elastic contraction combined with the mechanical locking of the thread, stable and reliable axial and radial constraint forces can be provided to ensure the connection is firm and maintain the integrity of the greenhouse frame.

Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
