[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1-4 The present invention provides the following technical solution: a soft-seal flap door hinge, comprising a base 1, a flap body 3 at the upper end of the base 1, a reinforcing plate 5 at the lower end of the flap body 3, a sealing ring 7 at the lower edge of the reinforcing plate 5, a connector 6 at the center of the lower end of the reinforcing plate 5, a circular groove 8 at the lower end of the connector 6, one side of the flap body 3 being connected to the base 1 via a flap door hinge 2, and the other side of the flap body 3 being connected to the base 1 via a flap positioning mechanism 4.

[0021] Specifically, the flap door hinge 2 includes a connecting plate 21, a pin 22, a hinge seat 23, a hinge plate 25, and screws 26. The connecting plate 21 is fixedly installed on one side of the upper end of the base 1. The hinge seat 23 is installed on the upper end of the connecting plate 21. The hinge plate 25 is installed inside the hinge seat 23. The hinge plate 25 and the hinge seat 23 are rotatably connected by the pin 22. The other side of the hinge plate 25 is fixedly connected to the flap body 3 by screws 26.

[0022] By adopting the above technical solution, when flipping the main body 3, the hinge plate 25 is fixed to the main body 3 by screws 26. When the main body 3 rotates, it will drive the hinge plate 25 to rotate. The rotation of the hinge plate 25 will drive the pin 22 to rotate inside the hinge seat 23, thereby facilitating the flipping of the main body 3.

[0023] Specifically, the hinge seat 23 has an oblong hole 24 on its side corresponding to the pin 22, and the pin 22 can move up and down inside the oblong hole 24.

[0024] By adopting the above technical solution, the setting of the waist-shaped hole 24 allows the pin 22 to move up and down in the waist-shaped hole 24, which can reduce the wear on the pin 22 and allow the flap body 3 to adapt to it for subsequent closing work.

[0025] In this embodiment, when flipping the main body 3, the hinge plate 25 is fixed to the main body 3 with screws 26. When the main body 3 rotates, it will drive the hinge plate 25 to rotate. The rotation of the hinge plate 25 will drive the pin 22 to rotate inside the hinge seat 23, thereby facilitating the flipping of the main body 3. The setting of the oblong hole 24 allows the pin 22 to move up and down in the oblong hole 24, which can reduce the wear of the pin 22 and allow the main body 3 to adapt to it for subsequent closing work. Example 2

[0026] The difference between this embodiment and Embodiment 1 is that the flip-plate positioning mechanism 4 includes a positioning plate 43, a sliding plate 44, a reset component 45, and a mounting groove 46. A mounting groove 46 is provided inside one side of the upper end of the base 1. A sliding plate 44 is disposed inside the mounting groove 46. A positioning plate 43 is disposed on the side of the sliding plate 44. A reset component 45 is disposed through the inside of the side of the sliding plate 44.

[0027] By adopting the above technical solution, before positioning and fixing the flip panel body 3, the positioning plate 43 is pressed first. The positioning plate 43 drives the sliding plate 44 to extend into the interior of the mounting groove 46 and drives the reset component 45 to compress. After the flip panel body 3 is fixed, the positioning plate 43 is released, and the reset component 45 drives the positioning plate 43 to be locked at the upper end of the flip panel body 3, so as to achieve the positioning of the flip panel body 3.

[0028] Specifically, the reset assembly 45 includes a spring 451 and a center rod 452. The center rod 452 is disposed through the inside of the side of the slide plate 44, and the spring 451 is sleeved on the surface of the center rod 452 on the side of the slide plate 44.

[0029] By adopting the above technical solution, when the slide plate 44 slides inward, it will cause the spring 451 on the surface of the center rod 452 to compress. After the flip plate body 3 is fixed, the positioning plate 43 is released. At this time, the spring 451 rebounds, thereby causing the positioning plate 43 to be locked at the upper end of the flip plate body 3.

[0030] Specifically, the flip-plate positioning mechanism 4 also includes a slide groove 41 and a slider 42. The upper end of the slide plate 44 is provided with a slider 42, and the upper end of the base 1 is provided with a slide groove 41 corresponding to the slider 42.

[0031] By adopting the above technical solution, the slider 42 inside the sliding groove 41 can easily drive the slide plate 44 to slide.

[0032] In this embodiment, before positioning and fixing the flip panel body 3, the positioning plate 43 is pressed first. The positioning plate 43 causes the sliding plate 44 to retract into the mounting groove 46. When the sliding plate 44 slides inward, it will cause the spring 451 on the surface of the center rod 452 to compress. After the flip panel body 3 is fixed, the positioning plate 43 is released. At this time, the spring 451 rebounds, thereby causing the positioning plate 43 to be locked at the upper end of the flip panel body 3. By sliding the slider 42 inside the sliding groove 41, the slider 42 can easily drive the sliding plate 44 to slide.

[0033] The working principle and usage process of this utility model are as follows: When using this utility model, the hinge plate 25 is fixed to the flip plate body 3 by screws 26 when flipping the flip plate body 3. When the flip plate body 3 rotates, it will drive the hinge plate 25 to rotate. The rotation of the hinge plate 25 will drive the pin 22 to rotate inside the hinge seat 23, thereby facilitating the flipping of the flip plate body 3. The setting of the oblong hole 24 allows the pin 22 to move up and down in the oblong hole 24, which can reduce the wear of the pin 22 and allow the flip plate body to move up and down. 3. It can adapt to the subsequent sealing work; before positioning and fixing the flip plate body 3, first press the positioning plate 43. The positioning plate 43 drives the slide plate 44 to retract into the installation groove 46. When the slide plate 44 slides inward, it will drive the spring 451 on the surface of the center rod 452 to compress. After the flip plate body 3 is fixed, release the positioning plate 43. At this time, the spring 451 rebounds, thereby driving the positioning plate 43 to be stuck at the upper end of the flip plate body 3. By sliding the slider 42 inside the sliding groove 41, the slider 42 can easily drive the slide plate 44 to slide.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
