DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example:

[0021] Reference Figure 1-3A one-button-startable excavator cab skylight structure comprises a frame 1, a groove 2 is provided at the top of the frame 1, and a through hole is opened at the center of the groove 2, a hinge seat 3 is installed at one end of the top outer wall of the frame 1, and a fixed frame 4 is installed at the other end of the hinge seat 3, opening components 6 are provided at both sides of the outer wall of the groove 2, and a glass 5 is installed at the center of the fixed frame 4;

[0022] A connecting rod 14 is welded to the inner wall of the top of the frame 1, and the outer wall of one side of the connecting rod 14 is rotatably connected to the limit strip 15. A limit plate 17 is welded to one end of the bottom outer wall of the fixed frame 4, and the outer walls of the limit plate 17 and the limit strip 15 are provided with pin holes distributed at equal distances, and pin shafts are inserted into the pin holes. Pull out the pin shafts on the limit strip 15 and the limit plate 17, start the electric push rod 8 to lift up one end of the fixed frame 4, so as to facilitate one-key opening of the glass 5 on the top of the frame 1, and facilitate small-angle fixing and large-angle opening.

[0023] The opening assembly 6 includes an embedded groove 7 provided on the top outer wall of the groove 2, an electric push rod 8 hinged at one end of the embedded groove 7, a fixing block 12 welded to the bottom outer wall of one end of the fixing frame 4, and a fixing groove 13 provided on the outer wall of one side of the fixing block 12;

[0024] The outer wall at the bottom of the top of the frame 1 is rotatably connected to a fixed handle 16 at one side of the fixed block 12, and a protrusion is welded on the outer wall of one side of the fixed handle 16, and the protrusion is slidably connected in the fixed groove 13;

[0025] One end of the electric push rod 8 is rotatably mounted on the bottom outer wall of the fixed frame 4, and a fitting adhesive strip 10 is fixed on the bottom outer wall of the fixed frame 4 at the edge of the glass 5, and a blocking strip 9 is welded on the top outer wall of the frame 1 located at the groove 2. The fitting adhesive strip 10 on the bottom outer wall of the fixed frame 4 cooperates with the blocking strips 11 on the four sides of the fixed frame 4 to seal and block the edge of the groove 2 on the frame 1 and the contact edge of the glass 5 and the groove 2, respectively, and cooperates with the blocking strip 9 to prevent rainwater from entering the interior;

[0026] The frame 1 is provided with a rain sensor 18 at the bottom of the glass 5, and the rain sensor 18 is connected to the excavator control terminal through a signal line. Blocking bars 11 are fixed to the four sides of the top outer wall of the fixed frame 4. When the rain sensor 18 detects rain on the fixed frame 4, it uploads a signal and starts the electric push rod 8 to retract the fixed frame 4. After the fixed frame 4 is closed, it is manually pulled back into the frame 1, and the fixed frame 4 is closed by entering the fixed groove 13 through the protrusion on the fixed handle 16, so that it is easy to close;

[0027] The electric push rod 8 is connected to the excavator control end through a wire, and the excavator controller is connected to the power supply through a wire.

[0028] Working principle: Install the whole in the frame 1 of the excavator cab. When in use, rotate the fixing handle 16 to make the protrusion leave the fixing groove 13 in the fixing block 12. At this time, since the electric push rod 8 is placed flat in the embedded groove 7, the fixing frame 4 cannot be lifted up. Manually push the fixing frame 4 upward to a certain angle, and use the limit bar 15 to cooperate with the pin hole in the limit plate 17 to insert the pin shaft to support the limit bar 15 and limit the opening angle of the fixing frame 4. When the fixing frame 4 needs to be fully opened, pull out the limit bar 15 and the pin shaft on the limit plate 17, start the electric push rod 8 to lift one end of the fixing frame 4, so as to open the glass 5 on the top of the frame 1 with one click.
