Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, for the utility model discloses a steel construction airtight door, including door leaf 1 and the door frame 11 of installing on wall body 14, door frame 11 includes two horizontal frames 13 and two munitions 12, and munition 12 and horizontal frame 13 welding are in the same place, and door leaf 1 is articulated with one of them munition 12, and door frame 11 and door leaf 1 pass through hinge connection, and door frame 11 is equipped with sealing strip 2 towards one side of door leaf 1.

As shown in fig. 2 and 3, in order to protect the sealing strip 2 and reduce the damage to the sealing strip 2, the side of the sealing strip 2 facing the door leaf 1 does not protrude from the side of the door frame 11 facing the door leaf 1. In this embodiment, 2 integrative settings of sealing strip, 2 sealing strips of sealing strip flush towards the side of door leaf 1 with door frame 11 towards the side of door leaf 1, reduce the collision of personnel to sealing strip 2 when passing through the airtight door, play the effect of protection sealing strip 2. One side that sealing strip 2 is close to wall 14 and the one side that deviates from wall 14 are equipped with recess 21, and one side that door leaf 1 is towards door frame 11 is equipped with the sand grip 22 that corresponds with recess 21, and in this embodiment, sand grip 22 sets up integratively. When the sealed door is closed, the convex strip 22 enters the groove 21, and the door leaf 1 is tightly propped against the sealing strip 2 on the door frame 11.

As shown in fig. 2 and 3, in order to further reduce the gap between the protrusion 22 and the groove 21 and improve the protection effect of the weather strip 2, the groove 21 of the mullion 12 is formed in an arc shape having a position where the door 1 and the door frame 11 are hinged as an axis and a horizontal distance between the groove 21 and the position where the door 1 and the door frame 11 are hinged as a radius, and the protrusion 22 corresponding to the mullion 12 is formed in an arc shape that is fitted to the inner wall of the groove 21 of the mullion 12. The groove 21 of the horizontal frame 13 is parallel to the radial direction of the rotation of the door 1, so that the groove can be arranged in a straight shape to be normally attached to the convex strip 22. The rib 22 is arranged away from a side fillet of the door leaf 1.

As shown in fig. 3, in order to further improve the sealing effect of the airtight door, the bottom of the groove 21 is provided with a rubber strip 3. When the sealing door is closed, the door leaf 1 is abutted to the sealing strip 2 on the door frame 11, and after the convex strip 22 enters the groove 21, the rubber strip 3 is abutted to the convex strip 22 to form triple sealing, so that the sealing effect is improved.

As shown in fig. 4, in order to further facilitate replacing the rubber strip 3, the rubber strip 3 abuts against the side wall of the groove 21, and a pull ring 31 is disposed on the rubber strip 3, in this embodiment, the pull ring 31 and the rubber strip 3 are integrally disposed. A tab 31 is provided at the junction of the transom 13 and the mullion 12. After the pull ring 31 is pulled out, the rubber strips 3 in the grooves 21 on the transverse frame 13 and the vertical frame 12 can be pulled at the same time, and the efficiency of replacing the rubber strips 3 is improved. The distance between one end of the pull ring 31 far away from the rubber strip 3 and the rubber strip 3 is larger than the distance between one side of the rubber strip 3 facing the door leaf 1 and one side of the door frame 11 facing the door leaf 1. A side face of the rubber strip 3 facing the pull ring 31 is provided with a caulking groove 32 for accommodating the pull ring 31, and the caulking groove 32 ensures the smoothness of the surface of the rubber strip 3 and reduces the gap between the convex strip 22 and the rubber strip 3.

The implementation principle of the embodiment is as follows: when the sealing door is closed, the door 1 is abutted with the doorframe 11, the convex strips 22 enter the grooves 21, the convex strips 22 are abutted with the rubber points, the door 1 between the convex strips 22 is abutted with the sealing gasket, and a gap between the doorframe 11 and the door 1 is sealed. When the rubber strip 3 needs to be replaced, the pull ring 31 is pulled, and the pull ring 31 drives the rubber strip 3 to slide out of the groove 21 along the side wall of the groove 21.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
