Description

Technical Field

[0001] The invention mainly relates to the technical field of civil air defense doors, and in particular to a civil air defense door with good sealing effect. Background Art

[0002] Civil defense doors are the entrances and exits of people's defense projects. They are the activities of the government to mobilize and organize the masses, take anti-air raid and disaster relief measures, implement rescue operations, and prevent and reduce disaster hazards. Civil defense doors are civil defense protection equipment. Civil defense doors are generally made of hard steel materials, which have a certain effect of preventing shock waves and effectively ensure the safety and stability of the interior of the civil defense space. However, during combat, due to the strong shock wave, the door body of the rigid structure often undergoes deformation of different shapes, thus affecting the sealing effect of the civil defense door itself.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: Existing civil air defense doors usually adopt a one-way bolt or a two-way bolt set inside the door to lock the door frame. However, when subjected to a strong impact, the transmission rod connected to the bolt is offset, causing the bolt to loosen, thereby affecting the sealing effect of the civil air defense door.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0024] See attached Figure 1-4 A civil air defense door with good sealing effect comprises a leaf door 1 and a sealing structure, a fireproof layer is provided between the sealing structure and the leaf door 1, a plurality of locking grooves 2 are provided on both sides of the leaf door 1, the sealing structure comprises a positioning drive module 3 and a linkage sealing module 4, the positioning drive module 3 is used to lock both sides of the leaf door 1, the linkage sealing module 4 is used to push the positioning drive module 3 for locking and fixing, the positioning drive module 3 comprises two sets of mirror-image active rods 31, the upper and lower ends of the active rod 31 are provided with rotating lock heads 32, one side of the active rod 31 is connected with a positioning shaft 34 through a pressure rod 33, the linkage sealing module 4 comprises a two-way linkage rod 41, pushing seats 42 are provided at both ends of the two-way linkage rod 41, and a turntable 44 is connected to the two-way linkage rod 41 through a swing rod 43.

[0025] The rotary lock 32 is located inside the door, and includes a rotating shaft 321, to which a sleeve 322 is connected. A lock 323 and a telescopic spring 324 are arranged in the sleeve 322. The sleeve 322 has a step hole, in which the lock 323 is placed. The telescopic spring 324 is installed at the tail of the lock 323. The lock 323 is pushed out of the sleeve through the pushing seat 42, and the lock 323 is extended out of the locking groove 2 until the sealing plate 325 presses the inner side of the door 1. When released, the lock 323 is automatically reset by the telescopic spring 324.

[0026] The active rod 31, the pressure rod 33, the positioning shaft 34 and the rocker 35 are all arranged outside the leaf door and are respectively located at the front and rear ends of the leaf door 1. The two ends of the active rod 31 are connected through the rocker 35 and the rotating shaft 321 on the rotary lock 32. After pushing the pressure rod 33 up and down, the pressure rod 33 rotates along the positioning shaft 34, driving the active rod 31 to move up and down, thereby rotating the rotary lock 32. When the active rod 31 moves up and down, the rotary lock 32 can achieve a 90-degree rotation.

[0027] The push seat 42 is kept moving in the horizontal direction up and down by the guide rod 45, and the two-way linkage rod 41 is telescopically movable through the swing rod 43. When extended, the push seat 42 is pushed out toward the rotating lock head 32, and when retracted, it is reset. One end of the swing rod 43 is connected to the turntable 44, and rotating the turntable 44 pulls the swing rod 43.

[0028] The rotating wheel 5 is located in the middle of the door 1 , and the rotating disk 44 is connected to the rotating wheel 5 through a driving shaft 46 , and the rotating disk rotates when the rotating wheel 5 is rotated.

[0029] In this embodiment, the leaf door 1 is connected to the door frame of the civil air defense door by a hinge; the implementation principle of a sealed civil air defense door in the embodiment of the present application is: when in use, after the leaf door 1 coincides with the door frame, the pressure rod 33 is pushed downward, and one end of the pressure rod 33 rotates with the positioning shaft 34 as a fulcrum, driving the active rod 31 to move downward. After the active rod 31 drives the rocker 35 and the rotating shaft 321 to rotate, the rotary lock 32 is driven to rotate, so that the rotary lock 32 rotates from a vertical state to a horizontal state, and one end of the lock 323 faces the locking groove 2; the rotating wheel 5 is rotated, and the rotating wheel 5 and the rotating disk 44 rotate at the same time, driving the swing rod 43 connected to the rotating disk 44 to move upward, extending the two-way linkage rod 41 to both sides, and pushing out the pushing seat 42 until the pushing seat 42 extends the lock 323 from the sleeve 322 into the locking groove 2 and inserts it into the door frame, thereby realizing the connection between the leaf door 1 and the door frame, and at this time, the sealing plate 325 presses the inner side of the leaf door 1 to achieve a compression seal on the locking groove 2.

[0030] In summary, when the lock head 323 in the positioning drive module 3 rotates 90 degrees, it docks with the locking groove 2, and then the lock head 323 is pushed out through the linkage sealing module 4, thereby locking the leaf door and the door frame, and then achieving the sealing effect of the rotating lock head 32 on the leaf door.

[0031] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
