[0038] The working principle of the first embodiment of the present invention is as follows:

[0039] The flip fixing plate 200 of the utility model is fixed on the door panel. When the door is closed, the hinged main board 100 and the sealing strip 600 touch the stop module and compress the spring 500, so that the spring 500 fits with the hinged main board 100. The hinged main board 100 and the flip fixing plate 200 are parallel to the door panel, and the sealing strip 600 seals the gap between the door bottom and the ground, thereby preventing insects, reducing noise, and saving energy.

[0040] When the door is opened, the hinged main board 100 and the sealing strip 600 are separated from the parking module and the spring 500 is no longer compressed, the spring 500 abuts against the hinged main board 100, the hinged main board 100 tilts up, and the sealing strip 600 no longer seals the gap between the door bottom and the ground.

[0041] Embodiment 2:

[0042] See also Figures 2 to 5 As shown, in the second embodiment, based on the first embodiment, a long handle portion 410 is further provided at the arched end of the right side plate 400 , and a rotating wheel 420 is provided on the long handle portion 410 of the right side plate 400 .

[0043] The working principle of the second embodiment of the present invention is as follows:

[0044] The flip fixing plate 200 of the utility model is fixed on the door panel. When the door is closed, the hinged main board 100 and the sealing strip 600 touch the stop module and compress the spring 500, so that the spring 500 fits with the hinged main board 100. During the compression of the spring 500, the rotating wheel 420 rolls upward along the door panel. The hinged main board 100 and the flip fixing plate 200 are parallel to the door panel, and the sealing strip 600 seals the gap between the bottom of the door and the ground, thereby preventing insects, reducing noise, and saving energy.

[0045] When the door is opened, the hinged main board 100 and the sealing strip 600 are separated from the parking module and the spring 500 is no longer compressed, and the spring 500 abuts against the hinged main board 100. During the gradual recovery of the spring 500, the rotating wheel 420 rolls downward along the door panel, the hinged main board 100 tilts up, and the sealing strip 600 no longer seals the gap between the bottom of the door and the ground.

[0046] The rolling wheel on the right side plate 400 mitigates the impact when the spring 500 is released from compression.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
