[0009] The utility model patent (CN 202325149 U) discloses a door with a door closing device, which includes a door body and a door seam closing device. The door seam closing device includes a manual transmission mechanism, a baffle plate, and the bottom end of the door body There is a concave cavity for placing the baffle and matching with the baffle, and the baffle is placed in the concave cavity. The transmission mechanism includes a worm, a worm wheel and a rotating handle. The rotation of the worm wheel and the worm is driven by the rotation of the rotating handle, so that the baffle The board moves up and down. The baffle of this technical scheme adopts polyolefin foam board, which has poor plasticity and flame retardancy, and needs to make a special door body suitable for the baffle. The scope of application is narrow, and it is not suitable for the bathroom as a residential fireproof room. The required dual-purpose (normal and fire) fire door problem, and the installation is troublesome

Embodiment 1

[0040] like figure 1 As shown, a door bottom gap sealing device, which is located at the bottom of the door body 6, includes a U-shaped guide sleeve 1, a foam glass block 2, a fixing piece, a reinforcement block 4 and an opening and closing bolt 5, and the fixing piece is a notched elastic Ring rubber sleeve 3.

[0041] The width of the U-shaped guide sleeve 1 and the foam glass block 2 is consistent with the width of the door body 6. The U-shaped open end of the U-shaped guide sleeve 1 is downward and fixed on the bottom of the door body 6. The two ends of the U-shaped guide sleeve 1 both sides All are provided with elongated chute 11.

[0042] like Figure 2~3 As shown, the height of the foam glass block 2 is greater than the height of the gap at the bottom of the door, and it is embedded in the opening end of the U-shaped guide sleeve 1. The two ends of the foam glass block 2 are provided with pin holes 21, and the elastic ring rubber sleeve 3 is located in the U-shaped g...

Embodiment 2

[0054] The door bottom gap sealing device of this embodiment is basically the same as that of Embodiment 1, the difference lies in that the fixing parts are two arc-shaped latches 7 .

[0055] like Image 6 As shown, the arc lock 7 includes an arc lock arm 71, a rotating shaft 72 and a magnet-absorbing piece 73. The arc-shaped lock arm 71 is fixed on the U-shaped guide sleeve 1 through the rotating shaft 72, and the magnet-absorbing piece 73 is fixed on the arc-shaped The bottom of the locking arm 71 is in contact with the outer edge, and a pressing portion 74 is provided above the arc-shaped locking arm 71 .

[0056] The installation process of this embodiment is as follows:

[0057] 1. Install and fix the reinforcing block 4 above the foam glass block 2, so that the outer pin hole 41 of the reinforcing block 4 is coaxial with the pin hole 21 of the foam glass block 2.

[0058] 2. Install the two arc locks 7 above the elongated chute 11 of the U-shaped guide sleeve 1 throug...
