Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example
[0017] See attached Figure 1-3As shown, a dustproof structure of a fire door comprises a fire door body 1, wherein perlite 2 is arranged inside the fire door body 1, an empty groove 3 is opened at the bottom end of the fire door body 1, a first fixing block 4 is fixedly connected inside the empty groove 3, a first spring 5 is fixedly connected to the top of the first fixing block 4, a connecting plate 6 is fixedly connected to the end of the first spring 5 away from the first fixing block 4, a fixing column 7 is fixedly connected to the bottom end of the connecting plate 6, a push plate 8 is fixedly connected to the end of the fixing column 7 away from the connecting plate 6, and a fireproof dustproof structure of a fire door comprises a fire door body 1, wherein the fire door body 1 ... Dust strip 9, the interior of the empty groove 3 is fixedly connected with a second fixed block 11, the right side of the second fixed block 11 is fixedly connected with a damping rod 12, the end of the damping rod 12 away from the second fixed block 11 is fixedly connected with an insertion rod 14, and the insertion rod 14 movably penetrates and extends to the right side of the fire door body 1, the second fixed block 11 and the opposite surface of the insertion rod 14 are fixedly connected with a second spring 13, and the second spring 13 is movably sleeved on the surface of the damping rod 12, the bottom end of the connecting plate 6 is fixedly connected with an insertion block 15, and the surface of the insertion rod 14 is provided with a groove 16.
[0018] An end of the insertion rod 14 away from the damping rod 12 is fixedly connected with an arc-shaped protrusion.
[0019] Two slide bars 10 are fixedly connected inside the empty slot 3 , and the slide bars 10 movably penetrate the connecting plate 6 .
[0020] Working principle: When in use, the fire door body 1 is installed with the door frame. When the fire door body 1 is closed, the arc-shaped protrusion at one end of the plug rod 14 contacts the door frame and is squeezed to drive the plug rod 14 to move. When the plug block 15 at the bottom end of the connecting plate 6 corresponds to the groove 16 on the surface of the plug rod 14, the first spring 5 rebounds and drives the connecting plate 6 to move downward and drive the plug block 15 into the interior of the groove 16. The connecting plate 6 drives the fixed column 7 to move, and the fixed column 7 drives the push plate 8 to move. The push plate 8 drives the dust strip 9 to move, so that the dust strip 9 is close to the ground. The dust strip 9 is used to block the gap between the fire door body 1 and the ground, thereby playing a dust-proof role. Through the setting of the sliding rod 10, it plays a role of stable support when the connecting plate 6 moves.
