Embodiment 1
[0040] Such as 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, and the two ends of the two sides of the U-shaped guide sleeve 1 All are provided with elongated chute 11.
[0042] Such as 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 i...
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] Such as 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 thr...
