[0028] The opening and closing mechanism 3 is disposed between the frame 1 and the movable window 2 , and can drive the movable window 2 to move so as to open or close the vent 100 .

[0029] By setting an opening and closing mechanism 3 between the frame 1 and the movable window 2, the opening and closing mechanism 3 can drive the movable window 2 to move to open the vent 100 for ventilation. It has a reasonable structure, ingenious design, low cost, and strong versatility. It is not only convenient and quick to operate, but also has good ventilation and temperature control effects and high heat dissipation efficiency. It will not cause damage to the film, thereby extending the service life of the film.

[0030] In this embodiment, preferably, the material of the frame 1 and the movable window 2 is aluminum alloy, which has high strength and long service life; of course, the material of the frame 1 and the movable window 2 can also be other metal or alloy materials already existing in the prior art, which is not limited here.

[0031] Furthermore, the opening and closing mechanism 3 includes an opening and closing connecting rod 31 hinged on the frame 1, and a guide groove 32 opened on the movable window 2. One end of the opening and closing connecting rod 31 is slidably connected to the guide groove 32. When the other end of the opening and closing connecting rod 31 is pulled down, the opening and closing connecting rod 31 rotates to drive the movable window 2 to move and open the vent 100.

[0032] In this embodiment, preferably, the material of the opening and closing connecting rod 31 is stainless steel, which has high strength and long service life; of course, the material of the opening and closing connecting rod 31 can also be other metal or alloy materials that already exist in the prior art, which is not limited here.

[0033] A locking mechanism 4 is further provided between the opening and closing connecting rod 31 and the movable window 2 , and the locking mechanism 4 can lock the relative position between the opening and closing connecting rod 31 and the movable window 2 after the movable window 2 moves to open the vent 100 .

[0034] The specific method of use is as follows: when closing the vent 100, push the opening and closing connecting rod 31 upward, and the opening and closing connecting rod 31 rotates to drive the movable window 2 to rotate toward the frame 1 until the movable window 2 covers the frame 1 to achieve sealing;

[0035] When ventilation is needed, the opening and closing connecting rod 31 is pulled down, and the opening and closing connecting rod 31 rotates in the opposite direction to drive the movable window 2 to rotate away from the frame 1, so that the movable window 2 is separated from the frame 1, until the opening and closing connecting rod 31 rotates to the locking mechanism 4 and is locked to achieve ventilation; the movable window 2 is driven by the opening and closing mechanism 3 to rotate to open or close the vent 100, so as to achieve ventilation and cooling of the greenhouse. The above-mentioned one-pull-to-open operation method is easy and convenient, saving time and effort.

[0036] Furthermore, a pull rope can be provided at the lower end of the opening and closing link 31, one end of the pull rope is tied to one end of the opening and closing link 31, and the other end of the pull rope is used for manual pulling by the user, that is, the manual operation end of the pull rope is arranged to hang down. Since the height of the greenhouse is generally three to four meters, in order to facilitate the user to reach the pull rope, the hanging end of the pull rope is generally about one and a half meters from the ground. Of course, the pull rope can also be designed to other lengths according to the specific height and needs of the user.
