[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the utility model, and this embodiment provides an opening and closing mechanism, which includes a movable part 100, a fixed part 200 and a driving part 300. The movable part 100 includes a fixed frame 101, and a movable frame 102 hingedly arranged with the fixed frame 101; the fixed part 200 includes a greenhouse skeleton vertical beam 201, and a transmission component 202 arranged on the greenhouse skeleton vertical beam 201, the fixed frame 101 is arranged on the greenhouse skeleton vertical beam 201, and the transmission component 202 is connected to the movable frame 102; the driving part 300 includes a protective component 301 connected to the transmission component 202, and an energy supply component 302 arranged in the protective component 301, the energy supply component 302 can drive the movable frame 102 to rotate through the transmission component 202, so that the top of the movable frame 102 can be opened or closed.

[0028] Specifically, the fixing frame 101 is connected to the greenhouse frame vertical beam 201 through the window frame fixing fixture 101a, and the number of greenhouse frame vertical beams 201 is set to two.

[0029] Furthermore, the transmission assembly 202 includes a transmission pipe 202 a disposed between two greenhouse frame vertical beams 201 , and a transmission member 202 b disposed between the transmission pipe 202 a and the movable frame 102 .

[0030] The transmission member 202b includes a ring gear 202b-1 sleeved on the transmission tube 202a, a rack 202b-2 disposed on the movable frame 102, and a limiting hoop 202b-3 disposed outside the ring gear 202b-1 and the rack 202b-2;

[0031] The ring gear 202b-1 and the rack 202b-2 are meshed and connected, wherein the end of the rack 202b-2 passes through a bolt and is fixed with a nut to prevent it from falling off, thereby limiting the maximum stroke and preventing it from falling off directly.

[0032] Preferably, the rack 202b-2 is arranged in an arc shape, and its arc is consistent with the rotation trajectory of the movable frame 102. The transmission member 202b is arranged in two groups, and the two groups are arranged to make the operation of the device more stable.

[0033] It should be noted that the protection assembly 301 includes a shaft changer 301a disposed on the transmission tube 202a, and a protection shell 301b disposed on the outer side wall of the shaft changer 301a.

[0034] Furthermore, the energy supply component 302 includes a winch 302a disposed in the protective shell 301b, and a chain 302b meshingly connected to the winch 302a, wherein a rain barrel can be manually hung on the chain 302b, so that in the case of heavy rain, when the staff does not have time to manually close the ventilation windows, the device can automatically close the ventilation windows to prevent bad weather such as wind and rain from having adverse effects on the plants in the greenhouse.

[0035] Particularly, the input end and the output end of the shaft changer 301a are connected to the reel 302a and the transmission tube 202a respectively, and when the reel 302a rotates, the transmission tube 202a can be driven to rotate.

[0036] When in use, the transmission tube 202a is driven to rotate by operating the chain 302b, thereby driving the movable frame 102 to flip, so as to realize the opening and closing of the ventilation window, avoiding the situation that the traditional ventilation window is not easy to close well.

[0037] Example 2, reference Figures 2 to 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a greenhouse ventilation window, which includes an opening and closing mechanism, and a main body 400, including a plurality of greenhouse bottom supports 401, and a greenhouse frame 402 arranged on the greenhouse bottom supports 401.

[0038] Specifically, the movable part 100 is installed on the side elevation of the greenhouse frame 402. The selection of the window position makes the air exchange effect in the greenhouse higher. Among them, the length of this ventilation window is not fixed, and it can be extended to the required length according to the length of the greenhouse. Multiple groups of support beams can be added in the middle of the ventilation window.

[0039] like Figure 4 The ventilation windows in the second window opening position are also installed on the side facades around the greenhouse, but the openings are opened from the bottom, and the effect of discharging the hot air inside the greenhouse is poor, and the air exchange efficiency in the greenhouse is lower. In the first window opening position, the ventilation windows are installed on the top of the greenhouse. Similarly, it is convenient for the hot air inside the greenhouse to be discharged, speeds up the discharge of hot air inside the greenhouse, and is beneficial to the air exchange in the greenhouse. However, since the top of the greenhouse is arched, the installation of such ventilation windows is more complicated and not easy to be well closed. Therefore, in summary, our device can be easily installed and well closed.

[0040] The rest of the structure is the same as that of Example 1.

[0041] When in use, the ventilation windows are installed on the side facades around the greenhouse, and the openings are opened from the top to facilitate the discharge of hot air inside the greenhouse, speed up the discharge of hot air inside the greenhouse, and facilitate air exchange in the greenhouse.

[0042] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0043] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0044] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.
