[0028] Example 2:

[0029] Based on Embodiment 1, a preferred embodiment of the door flapping anti-tipping device provided by this utility model is as follows: Figures 1-4 As shown: The limiting assembly 4 includes: a rotating rod 411, disposed on the outer wall of the pipe 1, the rotating rod 411 being rotatably connected to the pipe 1 via a bearing seat, and a pin groove being provided on the upper surface of the rotating rod 411; a support plate 412, disposed at the bottom of the rotating rod 411, and fixedly connected to the outer wall of the pipe 1; and a connecting rod 413, disposed on the other side of the flap gate 312, the connecting rod 413 being fixedly connected to the other side of the flap gate 312, and a sliding groove 414 being provided on the upper surface of the connecting rod 413, the other end of the rotating rod 411 being slidably connected to... On the inner wall of the sliding groove 414, a fixing plate 415 is provided at one end of the connecting rod 413. The fixing plate 415 is fixedly connected to one end of the connecting rod 413. A sliding frame 416 is provided on the outer wall of the connecting rod 413. The sliding frame 416 is slidably connected to the outer wall of the connecting rod 413. The sliding frame 416 is slidably connected to the outer wall of the rotating rod 411. A pin hole is opened on the upper surface of the sliding frame 416. A pin 417 is provided on the inner wall of the pin hole. The pin 417 is inserted into the inner wall of the pin hole. One end of the pin 417 is slidably connected to the inner wall of the pin groove.

[0030] Furthermore, in this embodiment, when it is not necessary to control the flap 312 to open the gap, the pin 417 can be slid upwards, and the pin 417 slides out from the inner wall of the pin slot and the inner wall of the pin hole. At this time, the sliding frame 416 can be slid, sliding on the outer wall of the connecting rod 413 and the outer wall of the rotating rod 411. The sliding frame 416 contacts the fixing plate 415, causing the sliding frame 416 to release the rotating rod 411. Rotating the rotating rod 411, the rotating rod 411... One end slides out from the inner wall of the sliding groove 414, and the rotating rod 411 falls on the support plate 412 to ensure that water can flow out normally in the pipe 1. When it is necessary to control the opening gap of the flap 312, the flap 312 can be opened after the other end of the rotating rod 411 slides out from the inner wall of the sliding groove 414. When it reaches the appropriate position, the rotating rod 411 is rotated back so that the other end of the rotating rod 411 slides into the inner wall of the sliding groove 414. Then the sliding frame 416 is slid back and the pin 417 is inserted into the pin hole and the inner wall of the pin groove.

[0031] In use, when it is not necessary to control the opening gap of the flap gate 312, the pin 417 can be slid upwards. The pin 417 slides out from the inner wall of the pin groove and the inner wall of the pin hole. At this time, the sliding frame 416 can be slid. The sliding frame 416 slides on the outer wall of the connecting rod 413 and the outer wall of the rotating rod 411. The sliding frame 416 contacts the fixing plate 415, causing the sliding frame 416 to release the rotating rod 411. The rotating rod 411 is rotated, and the other end of the rotating rod 411 slides out from the inner wall of the sliding groove 414. The rotating rod 411 falls on the support plate 412, ensuring that water can flow normally out of the pipe 1. Then, when the water flow in the pipe 1 is strong, it will impact the flap gate 312 open. The flap gate 312 drives the fixing block 311 to rotate on one side of the fixing plate 2. At the same time, the flap gate 312 drives the fixing frame 311 to rotate. 3. When sliding on the outer wall of connecting rod 1 314, flap 312 will collide with rotating plate 2 318. Rotating plate 2 318 drives connecting frame 319 to slide on the outer wall of connecting rod 1 314. Rotating plate 2 318 rotates on the outer wall of connecting frame 319. At the same time, rotating plate 2 318 will squeeze shock absorber 317. Shock absorber 317 buffers rotating plate 2 318. Shock absorber 317 will also drive rotating plate 1 316 to rotate, preventing flap 312 from flipping. When it is necessary to control the opening gap of flap 312, flap 312 can be opened after the other end of rotating rod 411 slides out from the inner wall of sliding groove 414. After reaching the appropriate position, rotating rod 411 is turned back so that the other end of rotating rod 411 slides into the inner wall of sliding groove 414. Then sliding frame 416 is slid back and pin 417 is inserted into the pin hole and the inner wall of pin groove.
