Door-bottom protection soundproof bar and protection door

Abstract

The invention discloses a door-bottom protection soundproof bar. The door-bottom protection soundproof bar includes a fixing frame, a movable bracket, a sound isolation sealing strip and a driving mechanism. The driving mechanism includes a sliding rod, a connection plate, a compression spring and a thimble; the connection plate is bent, a sliding way is arranged in the fixing frame, the compression spring and a sliding rod are arranged in the sliding way, the connection plate is connected with the sliding rod and the movable bracket respectively to form a four-connection-rod mechanism, when adoor is closed and in a completely closed state, the thimble at one end of the sliding rod is squeezed by the side of a door frame so that the sliding rod can transversely move in the sliding way, meanwhile the compression spring is in a compression state, the connection plate drives the movable bracket to move downward, the sound isolation sealing strip arranged in the movable bracket stretchesout downward, a gap at the bottom of a door is closed, when the door is opened, the sound isolation sealing strip is away from the ground when the movable bracket is automatically retracted, opening and closing of the door is not affected, no damage is caused to the ground, outside dust, peculiar smell, insects, cold and hot air flow and the like can be effectively prevented from entering the doorthrough the gap of the bottom of the door, and the indoor environment is protected.

Description

technical field

[0001] The invention belongs to the field of medical protective equipment, and in particular relates to a door bottom protective sound insulation strip and a protective door. Background technique

[0002] The protective door must have the three conditions of easy and reliable door opening and closing action, good protective sealing, and non-magnetic materials. There are two main closing forms for the existing medical protective door. One is the ordinary protective door, which uses manual closing of the door leaf, reed It is installed around the side of the door leaf, and the gap is fixed by the door gap, so that the reed is sealed and protected; the other is a pneumatic protective door, which uses manual closing of the door leaf, and the reed is installed on the inside of the door frame, and the air source of the air pump is used to hit the reed through the cylinder piston. Make the reed sealed and protected.

[0003] However, the existing magnetic resonance...
