[0028] As Figures 1-8 The ramp inner opening double-leaf protective sealed door shown in the drawing includes a slope door frame 5 fixedly connected to a side wall body 2, the bottom of the side wall body 2 has a ramp body 1, and the ramp body 1 and the side wall body 2 are both made of building materials such as reinforced concrete. Since the slope door frame 5 is also located above the ramp body 1, the slope door frame 5 is only inclined at the bottom, the two sides are still vertical, and the top is still horizontal. The slope door frame 5 includes an integrated embedded frame 505 and a configuration frame 506, the configuration frame 506 is located at the end face of the embedded frame 505, the shapes of the two are similar, and the centers of gravity are close, but the inner wall size of the embedded frame 505 is smaller than the inner wall size of the configuration frame 506, the outer wall size of the configuration frame 506 is smaller than the outer wall size of the embedded frame 505, the bottom edge upper surface of the configuration frame 506 is parallel to the upper surface of the ramp body 1, and the bottom edge upper surface of the configuration frame 506 is obviously higher than the upper surface of the ramp body 1.

[0029] The configuration frame 506 is rotatably connected with the main door body 3 through the first longitudinal shaft 503. In fact, in order to avoid the rotation of the main door body 3 from being hindered, the lowest part of the upper surface of the bottom edge of the configuration frame 506 is a plane 501, and the first longitudinal shaft 503 is inserted between the plane 501 and the inner top surface of the configuration frame 506. Correspondingly, the main door body 3 is provided with a first shaft hole 303 penetrating through the upper and lower surfaces near the edge, which is used for the first longitudinal shaft 503 to pass through to form a rotating pair. The configuration frame 506 is also rotatably connected with the secondary door body 4 through the second longitudinal shaft 504. Similarly, in order to ensure that the secondary door body 4 can rotate normally, the highest part of the upper surface of the bottom surface of the configuration frame 506 has a platform 502. Under normal circumstances, the upper surface of the platform 502 and the plane 501 are parallel to each other and are both horizontal, but the upper surface of the platform 502 is obviously higher than the plane 501. The configuration frame 506 is inserted between the platform 502 and the inner top surface. The secondary door body 4 is provided with a second shaft hole 403 penetrating through the upper and lower surfaces near the edge, which is used for the second longitudinal shaft 504 to pass through to form a rotating pair. Since the top edge of the configuration frame 506 is horizontal, the upper ends of the first longitudinal shaft 503 and the second longitudinal shaft 504 are flush. When the main door body 3 and the secondary door body 4 are parallel, the bottom surfaces of the main door body 3 and the secondary door body 4 are just fitted with the upper surface of the bottom edge of the configuration frame 506. That is to say, the bottom surfaces of the main door body 3 and the secondary door body 4 each have a small part of horizontal part and a large part of inclined part.

[0030] The main door body 3 and the secondary door body 4 are provided with a sealing structure between them and the inclined door frame 5 to ensure the airtightness between the main door body 3 and the secondary door body 4 and the inclined door frame 5 after being closed. Specifically, the end surface of the embedded frame 505 is provided with a sealing ring 507, which surrounds the inner wall of the embedded frame 505 and is located in the configuration frame 506. In addition, the side surface of the main door body 3 is provided with a first pressing groove 302, which is fitted with the sealing ring 507 when the main door body 3 rotates to the inside of the configuration frame 506. The side surface of the secondary door body 4 is provided with a second pressing groove 402, which is also used to fit with the sealing ring 507. In fact, the upper and lower ends of the second pressing groove 402 are aligned with the upper and lower ends of the first pressing groove 302, thereby forming a complete pressing groove structure that completely wraps the sealing ring 507. The side surface of the main door body 3 is also provided with a first fitting plate 301 located in the first pressing groove 302, which is used to fit with the inner wall of the embedded frame 505. The side surface of the secondary door body 4 is also provided with a second fitting plate 401 located in the second pressing groove 402, which is used to fit with the inner wall of the embedded frame 505. The first fitting plate 301 and the second fitting plate 401 located in the embedded frame 505 also fit with each other, which can effectively improve the structural strength of the protective airtight door after being closed. The first fitting plate 301 is provided with a lock body mounting groove 304 on the upper surface, which is used to mount the shell structure of the lock pin. The lock body mounting groove 304 is provided with a lock cylinder mounting hole 305 penetrating through the outer side surface of the main door body 3, which is used to mount the unlocking structure matched with the lock pin shell. The second fitting plate 401 is provided with a lock plate mounting groove 404 on the upper surface, which is used to mount the fixed plate structure of the intercepted lock pin.

[0031] The sealing structure is arranged between the main door body 3 and the auxiliary door body 4, and is used for improving the sealing property between the cooperation surface of the main door body 3 and the auxiliary door body 4. Specifically, the main door body 3 is provided with a clamping groove 307 on the side surface away from the first cooperation plate 301, the clamping groove 307 is located on the side edge of the main door body 3 which can be attached to the auxiliary door body 4, the main door body 3 is provided with a sealing groove 306 on the inner wall of the clamping groove 307, the auxiliary door body 4 is provided with a pressing plate 406 on the side surface away from the second cooperation plate 401, the pressing plate 406 is located on the side edge of the auxiliary door body 4 which can be attached to the main door body 3, and the side surface of the pressing plate 406 is provided with a sealing strip 405 which is just attached to the sealing groove 306 to form a sealing surface between the main door body 3 and the auxiliary door body 4.

[0032] Working principle: when closing, first rotate the main door body 3 into the configuration frame 506 until it is attached to the embedded frame 505, at this time, the first pressing groove 302 of the main door body 3 forms a C-shaped sealing surface with the sealing ring 507, then rotate the auxiliary door body 4 into the configuration frame 506 until it is attached to the embedded frame 505, at this time, the second pressing groove 402 of the auxiliary door body 4 forms a C-shaped sealing surface with the remaining part of the sealing ring 507, at the same time, the pressing plate 406 of the auxiliary door body 4 is attached to the clamping groove 307 of the main door body 3, and the sealing strip 405 forms a long strip-shaped sealing surface with the sealing groove 306, insert the key into the lock core and turn it, the lock pin will be inserted into the lock plate to limit the movement of the main door body 3 and the auxiliary door body 4, and the protective sealing door is in a locked state; when opening, turn the key in the lock core, the lock pin is separated from the lock plate, and then the auxiliary door body 4 and the main door body 3 can be opened in turn. Usually, in order to facilitate the quick opening of the protective sealing door, the key is not usually arranged, but a handle structure is arranged on the main door body 3 and is connected with the unlocking mechanism in the lock core, and it should be noted that the safety passage in the side wall 2 will slowly change from the inclined state aligned with the bottom edge of the configuration frame 506 to the horizontal state, and the old and the young will pass through more smoothly.
