Although the existing civil air defense doors can achieve auxiliary sealing through sealing gaskets, there is still room for improvement in the sealing effect, and multiple sealing cannot be achieved through structural improvements. Utility Model Content

[0003] In view of this, the utility model provides a civil air defense door with good sealing effect, which solves the problem that although the existing civil air defense door can achieve auxiliary sealing through sealing gaskets, there is still room for improvement in the sealing effect, and multiple sealing cannot be achieved through structural improvements.

[0005] The utility model provides a human air defense door with good sealing effect, specifically comprising: a door frame;

[0006] A sealing part is installed on the door frame.

[0007] Furthermore, the sealing part is composed of a connecting plate and a door plate. There are two connecting plates in total. Both connecting plates are rectangular plate structures. Both connecting plates are fixed on the door frame.

[0008] Furthermore, the two door panels are both stepped structures, and the steps of the two door panels are in contact with the inner wall of the door frame.

[0009] Furthermore, an auxiliary block is fixed to the rear end face of the door frame. The auxiliary block is a U-shaped structure. The front end face of the auxiliary block is in contact with the door panel. The auxiliary block is a sealing structure between the door frame and the door panel. When the door panel is closed, the door panel is in contact with the auxiliary block. The door panel can be sealed again through the contact between the door panel and the auxiliary block, thereby improving the sealing effect.

[0010] Furthermore, the rear end face of the door panel is welded with reinforcement blocks in a linear array, and the reinforcement blocks are rectangular block structures. The reinforcement blocks welded in a linear array together constitute the reinforcement structure of the door panel. During use, the door panel can be strengthened by the reinforcement blocks welded in a linear array, reducing the difficulty of the door panel being damaged.

[0011] Furthermore, a locking part is installed on the door frame, and the locking part is composed of a first locking block, a first connecting block, a mounting block, an electric cylinder, a first locking rod, a second connecting block, a second locking block, a second locking rod and a force block. The first locking block is fixed to the rear end face of the door frame, and the first locking block is a rectangular block structure, and a circular hole is opened on the first locking block.

[0012] Furthermore, the first connecting block is fixed on the rear end face of the door panel, and the first connecting block is a rectangular block structure; a mounting block is welded on the rear end face of the door panel, and the mounting block is a rectangular block structure. An electric cylinder is fixed on the top surface of the mounting block, and a first locking rod is fixed at one end above the electric cylinder. The first locking rod is slidably connected to the mounting block, and the first locking rod is aligned with the first locking block. When the electric cylinder is extended, the first locking rod and the first locking block are in a plug-in state.

[0013] Furthermore, a second connecting block is welded on the rear end surface of the door panel, and a second locking block is welded on the other door panel; a second locking rod is slidably connected to the second connecting block, and the second locking rod is a cylindrical rod-shaped structure.

[0014] Furthermore, a force block is welded to one end of the left side of the second locking rod, and the force block is a right-angled triangle structure;

[0015] The first locking rod is a T-shaped structure. When the first locking rod moves upward, the first locking rod contacts the inclined surface of the force-bearing block.

[0016] Beneficial Effects

[0017] A locking part is provided. Through the setting of the locking part, on the one hand, when locking, it can be driven by the electric cylinder, and electric locking can be realized, and the locking is convenient and fast; on the other hand, when the first locking block moves upward, it can push the force-bearing block to move laterally. When the force-bearing block moves laterally, the second locking rod and the second locking block can be plugged in, and double locking is completed. Compared with the existing device, the locking effect of the present device is better, and the locking of the two locking structures can be realized synchronously. When the locking of the two locking structures is realized, only one electric element is needed.

[0018] An auxiliary block is provided. Through the provision of the auxiliary block, when the door panel is closed, it contacts the auxiliary block, which can improve the sealing performance between the door handle and the door frame, thereby improving the sound insulation effect.
