[0020] As Figures 1-4The greenhouse ventilation pipeline shown comprises an outer shell 1, an inner shell 2 and a plurality of screw rods 5, the outer shell 1 and the inner shell 2 are consistent in structure and are both arranged in annular structures, a plurality of through holes 3 are formed in the outer shell 1 in annular equidistant arrangement, a plurality of inner threaded pipes 4 are fixedly connected to the inner shell 2 in annular equidistant arrangement, the plurality of through holes 3 and the plurality of inner threaded pipes 4 are in one-to-one correspondence, the through holes 3 and the inner threaded pipes 4 are matched with the screw rods 5, the end of the outer shell 1 and the inner shell 2 that are close to each other is both provided with an inner sealing ring 6, and the outer shell 1 and the inner shell 2 are coaxially arranged with the inner sealing ring 6.

[0021] The ventilation pipeline of the greenhouse is usually arranged on the side of the greenhouse to facilitate air circulation and temperature and humidity adjustment. In the existing mode, the user usually directly forms a ventilation hole on the plastic film and covers the hole with a cover cloth that can be opened to realize the opening and closing of the hole. In actual conditions, since the plastic film is flexible, the area after the hole is formed cannot be tightened, the hole cannot be protected, and the hole is easily torn or deformed under the action of wind, rain and other external forces, so that the hole cannot be closed when needed, thereby damaging the sealing of the greenhouse.

[0022] In the scheme, the user can place the outer shell 1 and the inner shell 2 on the outer side and the inner side of the plastic film respectively and make them abut against each other, so that the plastic film is clamped between the outer shell 1 and the inner shell 2. After aligning the positions of the outer shell 1 and the inner shell 2, the user passes the plurality of screw rods 5 through the plurality of through holes 3 respectively and threadedly connects them with the inner threaded pipes 4. After tightening the screw rods 5, the outer shell 1 and the inner shell 2 are firmly fixed together, and a pair of inner sealing rings 6 are tightly abutted against each other. At this time, the user can cut the plastic bottle on the inner side of the outer shell 1 and the inner shell 2 to form a ventilation hole. The outer shell 1 and the inner shell 2 can protect the plastic film around the hole. A pair of inner sealing rings 6 are extruded on the plastic film around the hole to limit the size of the hole, thereby avoiding deformation and expansion of the hole. Meanwhile, the outer shell 1 and the inner shell 2 can both be made of plastic light material to avoid that the overall device is too heavy to pull down the plastic film.

[0023] The end of the outer shell 1 away from the inner shell 2 is fixedly connected with a threaded ring 10, the threaded ring 10 is coaxially arranged with the outer shell 1, and a cover plate 11 is threadedly connected to the threaded ring 10.

[0024] In the scheme, when it is needed to close the hole, the user can threadedly connect the cover plate 11 to cover the opening of the outer shell 1, so as to quickly close the ventilation hole. The closing speed is fast, the fixation is firm, the cover plate 11 can be effectively prevented from falling off, and the good sealing of the hole is ensured.

[0025] The outer shell 1 and the inner shell 2 are provided with outer sealing rings 7 at one end close to each other, the outer shell 1 and the inner shell 2 are coaxially provided with the outer sealing rings 7, a pair of inner sealing rings 6 and a pair of outer sealing rings 7 are symmetrically arranged, the pair of inner sealing rings 6 are arranged at the inner side of the plurality of through holes 3 and the plurality of inner threaded pipes 4 respectively, and the pair of outer sealing rings 7 are arranged at the outer side of the plurality of through holes 3 and the plurality of inner threaded pipes 4 respectively.

[0026] In the scheme, when the outer shell 1 and the through hole 3 are fixed, the pair of inner sealing rings 6 are extruded, the plastic film around the hole can be fixed, and the pair of outer sealing rings 7 are also extruded together, the pair of outer sealing rings 7 can fix the plastic film outside the screw rod 5, because the installation of the screw rod 5 will pierce the plastic film, the outer sealing ring 7 can fix the plastic film outside the screw rod 5, which can prevent air from entering the greenhouse through the gap between the screw rod 5 and the plastic film.

[0027] The outer shell 1 is fixedly connected with a pair of magnets 8 at one end close to the inner shell 2, the inner shell 2 is fixedly connected with a pair of metal sheets 9 at one end close to the outer shell 1, and the positions of the pair of magnets 8 and the pair of metal sheets 9 correspond one by one.

[0028] In the scheme, when the user fixes the outer shell 1 and the inner shell 2, the user can first temporarily position the outer shell 1 and the inner shell 2 through the adsorption of the magnets 8 and the metal sheets 9, when the magnets 8 and the metal sheets 9 are adsorbed, the outer shell 1 and the inner shell 2 will be correctly fitted, and the positions of the plurality of through holes 3 and the plurality of inner threaded pipes 4 are also aligned one by one, so that the user can install the screw rod 5.

[0029] The outer shell 1 and the inner shell 2 are rotatably connected with a pair of supporting legs 12 at one end away from each other, the plurality of supporting legs 12 are inclinedly arranged, and the bottom end of the supporting leg 12 is provided in a sharp structure.

[0030] In the scheme, when the user completes the installation of the outer shell 1 and the inner shell 2, the user can support the outer shell 1 and the inner shell 2 on the ground through the plurality of supporting legs 12, construct a stable triangular structure, and further improve the stability of the placement of the outer shell 1 and the inner shell 2, the sharp design of the bottom end of the supporting leg 12 facilitates the insertion of the supporting leg 12 into the land, and improves the firmness of the fixation.

[0031] The specific implementation process is as follows:

[0032] In use, the user places the outer shell 1 and the inner shell 2 on the outer side and the inner side of the plastic film respectively, and makes them adhere to each other, the position of the outer shell 1 and the inner shell 2 is aligned through the adsorption of the magnet 8 and the metal sheet 9, the plastic film is clamped between the outer shell 1 and the inner shell 2, then the user makes the plurality of threaded rods 5 pass through the plurality of through holes 3 respectively and be screwed with the inner threaded pipes 4, the outer shell 1 and the inner shell 2 are firmly fixed together after the threaded rods 5 are tightened, and a pair of inner sealing rings 6 and a pair of outer sealing rings 7 are tightly abutted to each other, then the user cuts open the plastic bottle inside the outer shell 1 and the inner shell 2, the ventilation opening is realized, the closure of the opening can be realized by screwing the threaded ring 10 on the cover plate 11, finally the user props up the plurality of supporting legs 12 on the ground, which can support the outer shell 1 and the inner shell 2.
