In the specific embodiment of the utility model, the body 1 is the main part of the flap valve, providing structural support and the function of connecting other components. The base 2 is fixedly connected to the lower end of the body 1, and stable installation and adjustment of the height of the flap valve are realized through the thread groove 3. The rubber water stop ring 5 is fixedly connected to the upper end of the body 1 and mainly plays a role in sealing. It prevents liquid or other substances from flowing back into the room from the gap of the door, ensuring the water-proof performance and comfort in the room. The baffle 8 is connected to the upper end of the body 1, matches with the rubber water stop ring 5 and the body 1, further enhances the sealing performance of the door, and prevents the occurrence of backflow. The cooperation of the components can realize the function of preventing the reverse flowing of the flap valve, protect the indoor from being damaged by the reverse flowing of external liquid and ensure the safety and the drying of the indoor environment.

Referring to fig. 3-4, a reinforcing rib 4 is fixedly connected between the body 1 and the base 2, and the reinforcing rib 4 is integrally welded with the body 1 and the base 2.

In this embodiment: the reinforcing rib 4 is a part fixedly connected between the body 1 and the base 2 and is connected with the body 1 and the base 2 through integral welding. The anti-backflow flap valve has the function of enhancing the structural stability and strength of the anti-backflow flap valve. The presence of the reinforcing ribs 4 contributes to the resistance to external pressure and vibration, effectively enhancing the overall rigidity of the anti-backflow flap valve. It can absorb and disperse the force from the opening and closing movement of the door or the external impact force, reducing the stress concentration between the body 1 and the base 2. The reinforcing bars 4 can also provide additional support by means of a welded strong connection, ensuring a stable connection between the body 1 and the base 2.

Referring to fig. 2-4, a connecting seat 7 is fixedly connected to a side end of the body 1, and a connecting shaft 9 is rotatably connected between the baffle 8 and the connecting seat 7.

In this embodiment: the fixed connection of the connection seat 7 is to fix the side end of the body 1 in position stably, so as to ensure the stability of the whole structure. The connecting seat 7 provides a fulcrum enabling the baffle 8 to rotate. And the connecting shaft 9 serves as a rotatably connected member for connecting the baffle plate 8 and the connection seat 7. By the presence of the connecting shaft 9, the baffle 8 can perform a rotary movement under the support of the connecting seat 7, realizing the functions of opening, closing or other lateral movements. The connecting shaft 9 plays a role of supporting and transmitting force, and ensures stable connection and smooth movement between the baffle 8 and the connecting seat 7.

Referring specifically to fig. 5, a handle groove 14 is formed in the upper end of the baffle plate 8.

In this embodiment: the handle slot 14 is a slot or groove in the baffle plate 8, typically in the upper portion thereof. The design of the slot allows the user to grasp the baffle 8 and to achieve the control or adjustment by lifting or pushing the baffle 8. By providing a convenient, easy to grasp area by providing a handle slot 14, a user may obtain better grip and control when operating baffle-panel 8.

In this embodiment: intermittent engagement of ratchet 10 and ratchet 11 enables the connection shaft 9 to rotate in a direction and remain stable in a particular position. When the connecting shaft 9 rotates, the ratchet teeth 11 on the ratchet wheel 10 are alternately engaged with the ratchet teeth 11 on the connecting seat 7, so as to form locking or releasing actions. The torsion spring 12 provides elasticity between the connection seat 7 and the ratchet 11, so that the locking and releasing actions are smoother and controllable. The spring is capable of storing and releasing energy, providing sufficient force to stabilize the connection when the ratchet 11 is engaged, and allowing the ratchet 11 to disengage for rotation when required. The function of the reset block 13 is to assist the ratchet 11 in returning to the original position during locking and release. It is fixed to the side end of the ratchet 11 and when the ratchet 11 is disengaged, the reset block 13 applies force to return the ratchet 11 to the original position and ready for the next locking action.

Referring to fig. 1-3, the height of the body 1 is 15CM, and the upper end of the body 1 is fixedly connected with a shielding block 6.

In this embodiment: the shielding block 6 generally serves to prevent external objects or observers from directly seeing or interfering with the interior of the body 1. It may block vision, protect mechanical structures or sensitive components, or provide an aesthetic appearance. The shutter 6 may also provide privacy protection, limiting direct access to the interior of the body 1, by setting the height of the body 1 to 15CM so that the individual can facilitate their touching or pushing of the flap in order to open and close the door lock.

What needs to be explained is: the specific type of ratchet 10, ratchet 11, torque spring 12 and reset block 13 used is selected by those skilled in the art, and the above related art is not repeated in this scheme.

The working principle and the using flow of the utility model are as follows: first, the base 2 is fixedly connected to the lower end of the body 1, so that the threaded groove 3 at the bottom end of the base is aligned with the installation position. The upper end of the body 1 is fixedly connected with a rubber water stop ring 5. The reinforcing ribs 4 are integrally welded with the body 1 and the base 2, so that the strength and the stability of the structure are improved. A connecting seat 7 is fixedly connected to the side end of the body 1. The baffle 8 is matched with the rubber water stop ring 5 and the body 1, so that stable connection is ensured. The connecting shaft 9 is rotatably connected with the connecting seat 7 to realize the rotatable function of the baffle 8. The upper end of the baffle plate 8 is provided with a handle groove 14 so as to be convenient for a user to take and use. The circumferential surface of the connecting shaft 9 is fixedly connected with a ratchet 10. The side end of the connecting seat 7 is rotationally connected with the ratchet 11 through a rotating shaft. A torque spring 12 is connected between the ratchet 11 and the connection seat 7 to provide a certain elastic resistance. The side ends of the ratchet 11 are fixedly connected with a reset block 13, ensuring a gap between the ratchet and the ratchet in a specific operation. The height of the body 1 is 15 cm, and the shielding block 6 is fixedly connected to the upper end of the body 1, so that the water can be prevented from flowing backwards, and water or other liquid can be effectively prevented from flowing backwards through the design of the rubber water stop ring 5 and the baffle plate 8. This sealing design ensures that the interior of the door remains dry and clean, preventing damage caused by water or irrigation.
