Description

Technical Field

[0001] The utility model belongs to the technical field of balanced doors, and in particular relates to a balanced door with an exposed torsion axis. Background Art

[0002] Balanced doors are primarily used on the exteriors of buildings. When strong winds are blowing outside, ordinary doors must resist the force of the wind, requiring considerable force to open. However, balanced doors utilize the pressure differential created by wind, using a hidden sliding balancing arm between the door and the doorframe. This allows the door to be opened with minimal force, even in windy conditions.

[0003] Existing balanced doors usually use an exposed torsion shaft to drive the support arm to rotate. However, for taller balanced doors, a longer torsion shaft is usually required. After long-term use, the torsion shaft is easily deformed and bent, thereby affecting the pressure balance of the balanced door and affecting normal use. Utility Model Content

[0005] An embodiment of the present utility model is implemented as follows: a balanced door with an exposed torsion axis comprises a door frame, a door panel and a torsion axis, the door frame comprising a plurality of mounting tubes mounted on one side of the door frame and a plurality of mounting plates fixedly arranged between the door frame and the mounting tubes, the inner top and bottom surfaces of the door frame are provided with card slots and movable slots, the door panel comprises a plurality of movement slots and two movable columns, handles are fixedly mounted on both sides of the door panel, the movement slot is fixedly opened in the door panel, a mounting slot is fixedly opened in the movement slot, the two movable columns are fixedly mounted on the top and bottom ends of the door panel and movably located in the movable slot, the torsion axis is movably mounted in the mounting tube, two support arms are fixedly mounted on the outside of the torsion axis, a fixed block is fixedly provided at one end of the support arm, and the fixed block is movably engaged in the mounting slot.

[0010] The beneficial effects of the present invention are:

[0011] 1. The embodiment of the present invention provides a torsion shaft balancing door, which supports the torsion shaft through the multiple mounting tubes to prevent the torsion shaft from bending and deformation. The cooperating fixed blocks are engaged in the mounting grooves, which facilitates the support and fixation of the door panels through the multiple supporting arms to prevent the door panels from bending and deformation. At the same time, it can also further support the torsion shaft. The movable columns are movable in the movable grooves and cooperate with the supporting arms to balance the forces, thereby reducing the force required for opening and closing the door.

[0012] 2. An embodiment of the present invention provides a balanced door with an exposed torsion shaft, which facilitates the clamping and fixing of the two ends of the torsion shaft through the provided card slots. The torsion spring installed on the outside of the sleeve is matched with the first card block and the second card block. When the balanced door is opened, the torsion spring is squeezed to accumulate elastic potential energy, which facilitates the automatic closing of the balanced door.

[0013] 3. An embodiment of the present invention provides a balanced door with an open torsion axis. The ball bearing cooperates with the limiting groove on the outer side of the movable column to play an auxiliary role when the movable column moves, thereby reducing friction resistance and thus reducing the force when opening the door. The limiting block used to limit the ball bearing can prevent the ball bearing from moving freely, thereby reducing the occurrence of malfunctions. BRIEF DESCRIPTION OF THE DRAWINGS
