Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a security door with a closing mechanism, including a security door body 2, a fixed baffle 6, a rotating baffle 10, and a bending handle 15. A takeout opening 3 is provided on the side surface of the security door body 2. A reinforcing ring 4 is fixed to the inner wall of the takeout opening 3, and a sealing rubber ring 5 is fixed to the inner side of the reinforcing ring 4. The fixed baffle 6 is fixed inside the right side of the reinforcing ring 4. A sealing plate 7 is attached to the left end face of the fixed baffle 6. A damping bearing 8 is embedded between the sealing plate 7 and the left side of the fixed baffle 6. A positioning groove 9 is provided at the lower left end of the sealing plate 7. A rotating shaft 11 is horizontally installed at the left end inside the damping bearing 8. A rotating baffle 10 is fixed outside the rotating shaft 11, and the rotating baffle 10 slides against the upper side of the inner wall of the reinforcing ring 4. A diamond groove 12 is provided at the left end of the rotating shaft 11. A diamond rod 13 is movably inserted into the diamond groove 12. A handle 14 is longitudinally fixed at the left end of the diamond rod 13. A bending handle 15 is longitudinally fixed at the lower end of the handle 14. This design solves the problem that it is more dangerous to install the motor inside the door in the original device.

[0019] As the first embodiment of this utility model: the main body 2 of the anti-theft door is installed in the anti-theft door frame 1 by a hinge, the sealing plate 7 is attached and fixed to the lower right side of the sealing rubber ring 5, and the rotating baffle 10 slides and attaches to the upper left side of the sealing rubber ring 5. By adding the sealing rubber ring 5, the sealing plate 7 can be prevented from directly contacting the rotating baffle 10, so that the sealing plate 7 will not be rubbed when the rotating baffle 10 rotates.

[0020] The lower end of the bending handle 15 is inserted into the positioning groove 9. By inserting the lower end of the bending handle 15 into the positioning groove 9, the rotating baffle 10 can be locked by the grip 14, the diamond-shaped rod 13, and the rotating shaft 11, preventing the rotating baffle 10 from rotating on its own. The bending handle 15 is wrapped with a textile sleeve, which improves the user's grip on the bending handle 15.

[0021] As a second embodiment of this utility model: In actual use, the lower end of the bending handle 15 is inserted into the positioning groove 9, thereby locking the rotating baffle 10 through the grip 14, the diamond rod 13, and the rotating shaft 11, so that the rotating baffle 10 will not rotate on its own. When the user does not open the anti-theft door body 2 indoors and takes out takeout through the takeout opening 3, he / she can grasp the bending handle 15 and pull it forward slightly, so that the diamond rod 13 moves forward slightly in the diamond groove 12, and at the same time, the lower end of the bending handle 15 moves from the positioning groove 9. After the food is removed from the slot 9, slowly rotate the bending handle 15. This will cause the rotating baffle 10 to rotate via the grip 14, the diamond-shaped rod 13, and the rotating shaft 11. Once the rotating baffle 10 has rotated 180 degrees, it will overlap with the sealing plate 7 and the fixed baffle 6, and the space at the upper end of the reinforcing ring 4 will be connected. At this point, the user can take the food from outside through the takeout opening 3. After taking the food from outside, the takeout opening 3 can be closed by repeating the reverse steps. This is quick and convenient.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
