[0028] Example 1

[0029] See attached Figure 1-2A large mechanical portable front window opening and closing device of this embodiment includes a first mounting member 100, a second mounting member 200 and a third mounting member 300. The first mounting member 100 is mounted on the front window, the second mounting member 200 is mounted on the mounting frame of the front window, and the third mounting member 300 is mounted vertically on the second mounting member 200. A slide groove 110 is provided on the first mounting member 100, and a rotating rod 210 is provided on the second mounting member 200. The middle part of the rotating rod 210 is rotatably connected to the second mounting member 200. A sliding shaft is provided at one end of the rotating rod 210, and the sliding shaft is located in the slide groove 110. The other end of the rotating rod 210 is connected to a connecting rod 220, and the connecting rod 220 is connected to an electric push rod 230. The electric push rod 230 is mounted on the third mounting member 300. The structure of this design , used for opening and closing the front window of construction machinery. When the front window needs to be opened, the output shaft of the electric push rod 230 is retracted, and the rotating rod 210 is driven to rotate through the connecting rod 220, so that the end of the rotating rod 210 connected to the slide groove 110 is tilted upward, pushing the front window to rotate upward and present an open state, wherein the slide shaft slides accordingly in the slide groove 110, and vice versa to close the front window. This structural design is fully automated. By changing the position where the middle part of the rotating rod 210 is connected to the second mounting member 200 or changing the length of the force arm at both ends of the rotating rod 210, the opening and closing angle of the entire window and the relative force of the window can be adjusted, so that the design of the opening and closing angle can be realized, and the electric push rod 230 can be realized to achieve large-force opening and closing. Even if the front window is a little stuck due to long-term use, it can be opened and closed correctly.

[0030] The middle part of the rotating rod 210 of the present embodiment is mounted on the second mounting member 200 through a rotating shaft, and the central axis of the output shaft of the electric push rod 230 passes through the center of the rotating shaft. With this design structure, when the output shaft of the electric push rod 230 is fully retracted, the opening and closing angle of the front window can be adjusted by changing the length of the connecting rod 220, that is, if the connecting rod 220 is also in a horizontal state, the rotating rod 210 is also in a horizontal state, and this is the maximum opening and closing of the front window. Therefore, the opening and closing angle can be changed by changing the position where the middle part of the rotating rod 210 is connected to the second mounting member 200 as mentioned above. Since the design of the front window is fixed, when the position where the middle part of the rotating rod 210 is connected to the second mounting member 200 is relatively high, the rotating rod 210 is horizontal and the opening and closing angle is large. When the position where the middle part of the rotating rod 210 is connected to the second mounting member 200 is relatively low, the rotating rod 210 is horizontal and the opening and closing angle is small.

[0031] In this embodiment, a positioning groove 310 is provided on the third mounting member 300 , and a positioning shaft is provided on the connecting rod 220 . The positioning shaft is located in the positioning groove 310 to maintain the stable operation of the connecting rod 220 .

[0032] In this embodiment, the central axis of the positioning groove 310 and the central axis of the output shaft of the electric push rod 230 are located in the same horizontal plane.

[0033] In this embodiment, both ends of the connecting rod 220 are provided with connecting pieces 221 , and the connecting rod 220 is connected to the rotating rod 210 and the electric push rod 230 respectively through the connecting pieces 221 .

[0034] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
