Embodiment Construction

[0016] like figure 1 and figure 2 As shown, a lifting threshold device for a soundproof door includes a base 1 and a threshold support device above the base 1; it also includes a lifting threshold 3 above the threshold supporting device, and the lifting threshold 3 and the A lifting drive device and a lifting control device are arranged between the bases. When the door is opened, the lifting threshold is kept level with the ground. When the door is closed, the threshold is pushed upwards, which improves the sealing performance between the door frame and the door leaf, and ensures the sound insulation effect of the soundproof door.

[0017] The base 1 is installed in the groove 4 of the floor, the threshold support device includes a threshold support plate 2, the threshold support plate 2 is fixed at the edge of the groove 4, and the threshold support plate 2 is supported on the lifting platform. During the lower surface of threshold 3, the upper surface of lifting threshold...

Abstract

The invention relates to a lifting doorsill device for a soundproof door. The lifting doorsill device comprises a base and a doorsill supporting device located on the base. The lifting doorsill device further comprises a lifting doorsill located on the doorsill supporting device. A lifting driving device and a lifting control device are arranged between the lifting doorsill and the base. When the door is opened, the lifting doorsill is kept horizontal relative to the ground. When the door is closed, the doorsill is pushed to move upwards. The sealing performance between a door frame and a door plank is improved, and the soundproof effect of the soundproof door is guaranteed.

Description

technical field [0001] The invention relates to a lifting threshold for a sound insulation door. Background technique [0002] With the development of society, the offices, conference rooms, and lecture halls of some state-secret units with high requirements and standards, the operating room, nursing room, psychological consultation room of the hospital, the multimedia classroom of the school, the professional audition room, and the broadcasting room all require isolation. Sound insulation measures with relatively high sound performance, and the sound insulation performance of the door directly affects the sound insulation effect of the entire room, and is also the short board of sound insulation for the entire room. The requirements for the doors in the places mentioned above are particularly strict. No threshold can be left on the door, and there are higher requirements for sound insulation performance. This has caused many manufacturers to say that it cannot be realized,...
