door

Abstract

The invention discloses a house door, which belongs to the field of building supplies, and can eliminate the resistance of opening and closing the door, and eliminate the vibration sound caused by the opening and closing of the door to other doors and windows. The technical scheme of the present invention is achieved in that it comprises a door, a square valve door is processed on the door, and a valve with a counterweight is installed on the valve door.

Description

Technical field: [0001] The invention belongs to the field of building supplies, and specifically refers to a house door. Background technique: [0002] The door is an indispensable device in various buildings such as classrooms. Its main function is to play the role of opening and closing, which is convenient for people to enter and exit and can separate the building space. The requirements are very high, and the separation space inside and outside the room is closed and independent. In this way, every time the door is opened and closed, it often encounters the problem of excessive resistance caused by the air not flowing quickly in the relatively closed space, which makes the opening and closing of the door relatively difficult. At the same time, this kind of door opening and closing activities will also disturb the air pressure in the room to cause an instantaneous increase or decrease, that is, positive or negative pressure, which will not have any effect on the wall of ...

[0002] The door is an indispensable device in various buildings such as classrooms. Its main function is to play the role of opening and closing, which is convenient for people to enter and exit and can separate the building space. The requirements are very high, and the separation space inside and outside the room is closed and independent. In this way, every time the door is opened and closed, it often encounters the problem of excessive resistance caused by the air not flowing quickly in the relatively closed space, which makes the opening and closing of the door relatively difficult. At the same time, this kind of door opening and closing activities will also disturb the air pressure in the room to cause an instantaneous increase or decrease, that is, positive or negative pressure, which will not have any effect on the wall of the fixed object. , and acting on other doors and windows will produce a lot of vibration sound due to the inevitable joint gap. In some occasions, these sounds should not be produced, such as hospitals that require quietness, student classrooms that require quietness, etc., the above All kinds of problems need to be eliminated, but there is no product design plan to eliminate the above phenomena in the widely seen door products
