in more detail:
with reference to figures 1 to 5 of the drawings,
the working principle of the primary sealing assembly is as follows:
the present embodiment is installed by conventional means, and it needs to be noted that: exposing a valve (which can comprise a motor) reserved outside the sealing box out of the wall; in the using process, when the door body is closed, the door body can be used for unreeling the sealing modules (namely, the first sealing film, the first inflatable body, the second sealing film and the third inflatable body) on the rolling and rotating shaft through the driving motor, specifically referring to fig. 2, when the gravity block fixedly connected with the bottom of the second inflatable body enters the sealing groove, the motor is controlled to stop, at the moment, each valve is opened, each gas pipe is inflated through each valve through the gas pump, the inflated gas enters the first inflatable body, the second inflatable body and each third inflatable body until each inflatable body is filled, and when each inflatable body is filled, the valve is closed; when people need to be opened for passing, the steps are operated in the direction;
the advantages are that: when the door body is closed, the sealing module is arranged in the access passage to seal the access passage, so that the sealing performance is improved, and the door body is specifically as follows:
when the sealing module is unreeled, each third inflation body is positioned in a sliding groove arranged on the cavity wall on the two sides of the access passage, the first inflation body is positioned at the connecting opening, the second inflation body is positioned at the notch of the sealing groove, when the three inflation bodies are inflated by an air pump, each inflation body respectively fills the connecting opening, the sliding groove and the notch of the sealing groove, the three inflation bodies are further sealed, the sealing effect on the sealing cavity is further achieved, the sealing cavity is matched with the re-sealing of the door body, the double sealing effect can be achieved, and compared with the single sealing effect, the sealing effect of the first inflation body is far higher than that of the second inflation body;
it should be noted that:
one, in order to guarantee at the smooth and easy nature and the compactness of sealed module rolling or unreeling, it has aerifyd the bottom fixed connection of body at the second and has had the gravity piece, promptly: the self weight of the re-standing block can ensure the smooth unwinding of the sealing module; when the sealing module is rolled, the rolling tightness of the sealing module can be ensured by the weight of the sealing module;
secondly, in order to ensure the positioning effect of the gravity block during lifting and the sealing effect of the third inflatable body on the sealing cavity, the wall of the sealing cavity is provided with a chute for the gravity block to move, and on the other hand, each third inflatable body can be filled in each chute during inflation, so that the sealing performance of the sealing cavity is improved;
thirdly, the cross section of the gravity block is arranged to be an isosceles triangle, and the sealing groove is arranged at the bottom of the access passage for the purpose that: referring to fig. 2, when the gravity block descends, the gravity block can enter the sealing groove, which can be more convenient, that is: the tip of the isosceles triangle is used for guiding the isosceles triangle, so that the isosceles triangle and the isosceles triangle are matched more smoothly;
fourthly, referring to fig. 3, the gas pipe in the seal box may be a "spiral" gas pipe, for the purpose of: an air pipe with enough length is reserved in the sealing box, and when the sealing module is wound by the rotating shaft, the air pipe can be wound and adjusted along with the air pipe to be normally wound and unwound by the sealing module;
fifthly, referring to fig. 2, the cross-sectional shapes of the connection port, the first inflation body and the second inflation body are all set to be isosceles trapezoid, so that: the sealing performance of the connecting port is improved by increasing the contact area between the first inflation body and the connecting port, and due to the size change of the first inflation body and the connecting port (namely: the upper bottom L1 is equal, and the lower bottom L2 is equal), when the sealing module is rolled up, the second inflation body can partially enter the connecting port, namely: when the sealing module is not used, the sealing performance of the sealing cavity can be further improved, and further, various rotations are provided for the use method of the embodiment, in detail: in the above means, the gas in each inflation body can be partially pumped away, a part of gas is reserved in each inflation body, when the sealing module is rolled, the gas in the first inflation body and the third inflation body can gradually flow into the second inflation body, when the sealing module is rolled to a proper state, the reserved gas can partially fill the second inflation body, and then the connecting port is sealed by the second inflation body in the state;
in order to improve the sealing performance of the door body and the entrance of the access passage, a secondary sealing component is arranged on the matching surface of the door body and the door frame to improve the sealing effect of the door body and the entrance of the access passage;
the principle of the secondary seal assembly is as follows:
referring to fig. 1, fig. 4 to fig. 5, after the door body is closed, the first sealing rubber body and the second sealing rubber body arranged on the door body enter the closed cavity arranged on the door frame, and the first sealing rubber body is in contact with the outer side cavity wall of the closed cavity, and the second sealing rubber body is in contact with the inner side cavity wall of the closed cavity, so that the sealing effect between the door body and the door frame is improved by arranging the double-layer sealing rubber bodies;
moreover, in order to enable the first sealing rubber body and the second sealing rubber body to be respectively in close contact with the outer side cavity wall and the inner side cavity wall of the sealed cavity, the pressing module arranged between the first sealing rubber body and the second sealing rubber body (namely in the mounting groove) is used for: after the door body was closed, through opening the control valve who locates the external side of a body, and utilize external air pump to inflate the inside first gasbag body and the second gasbag body of mounting groove through this control valve and charging connector, after first gasbag body and second gasbag body were full of gas, the second gasbag body propped up each pressure plate (first gasbag body propped up each connecting rod), and make each articulated shaft rotate, finally make each pressure plate exert pressure respectively to first sealing rubber body and second sealing rubber body, and then make first sealing rubber body and second sealing rubber body inseparabler with the chamber wall complex of airtight chamber, and then improve its sealed effect.
Example 2 is different from example 1 in that
As shown in fig. 6, in the embodiment of the present invention, a third sealing rubber body 7 having a sealing installation groove 423 is fixedly connected between one side of the first sealing rubber body 421 away from the door body 10 and one side of the second sealing rubber body 422 away from the door body 10.
By adopting the technical scheme: in order to ensure that the first sealing rubber body and the second sealing rubber body can smoothly enter the closed cavity when the door is closed, a third sealing rubber body is arranged between the first sealing rubber body and the second sealing rubber body; further, seal the mounting groove through the third sealing rubber body, after the mounting groove is sealed, it also can protect first gasbag body and second gasbag body, guarantees the stability of its use.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
