TECHNICAL FIELD

[0001] The present application relates to the technical field of doors and windows, in particular to a door and window structure with sealing performance. BACKGROUND

[0002] Doors and windows are important components of buildings and are key components for heat preservation and insulation. They also lose the most heat compared to other building envelope structures such as walls and roofs. Doors and windows are generally composed of glass and a door and window frame. Indoor heat, outdoor cold air, and outdoor dust and water vapor can easily pass through the gaps between the glass and the door and window frame, thereby weakening the heat preservation, insulation, and waterproofing effects. Therefore, the sealing performance of existing doors and windows is not good, which affects the user experience and needs to be improved. SUMMARY

[0003] In order to improve the sealing performance of doors and windows, the present application provides a door and window structure with sealing performance.

[0007] Preferably, the pressing assembly includes a rotating rod, a first protrusion arranged on the rotating rod, and a driving member for driving the rotating rod to rotate. The rotating rod is rotationally connected to the inner wall of the door and window frame. When the sealing strip is not deformed, the sealing strip is located on the rotation path of the first protrusion. When the first protrusion rotates with the rotating rod to face the sealing strip, the sealing strip abuts against the side wall of the glass.

[0008] By adopting the above technical solution, the driving member drives the rotating rod to rotate, so that the first protrusion rotates with the rotating rod to face the sealing strip and press the sealing strip against the side wall of the glass.

[0009] As preferred, the driving member comprises driving rods, locking components, connecting ropes and reset torsional springs; each side of the glass corresponds to a driving rod, the connecting ropes are arranged one by one corresponding to the rotating rods, one end of the connecting rope is connected to the rotating rod, the other end of the connecting rope of all rotating rods on the same side of the glass is wound on the same driving rod, the driving rod is rotationally connected to the side wall of the door and window frame, and the locking component is used for fixing the rotating position of the driving rod; the reset torsional spring is arranged one by one corresponding to the rotating rod, and the reset torsional spring is sleeved on the corresponding rotating rod, one end of the reset torsional spring is connected to the rotating rod, the other end is connected to the side wall of the door and window frame, and when the reset torsional spring is not deformed, the first protrusion is located on one side of the rotating rod away from the sealing strip.

[0010] By adopting the above technical scheme, rotating the driving rod can make all the rotating rods on one side of the glass rotate, so that all the first protrusions on one side of the glass can rotate and abut against the side wall of the glass, and after the first protrusion rotates and abuts against the side wall of the glass, the rotating position of the rotating rod can be fixed by the locking component to maintain the abutting state of the first protrusion, the sealing strip and the glass.

[0011] As preferred, the side wall of the door and window frame is provided with an insertion slot for inserting the end of the glass, the side wall of the insertion slot is provided with a through hole, the abutting assembly further comprises a second protrusion, the second protrusion is slidingly connected to the side wall of the door and window frame, and the sealing strip close to the through hole is located on the sliding path of the second protrusion; the driving member is used for driving the second protrusion to slide, so that when the second protrusion slides towards the direction close to the through hole, the sealing strip close to the through hole is pushed into the through hole.

[0012] By adopting the above technical scheme, the driving member drives the second protrusion to slide towards the direction close to the sealing strip, so that the second protrusion pushes the sealing strip located at the through hole into the through hole and makes it abut against the side wall of the glass, further optimizing the sealing performance of the sealing strip on the joint between the glass and the door and window frame.

[0013] As preferred, the driving member further comprises driving blocks and reset springs; the driving blocks, connecting ropes, reset springs and second protrusions are arranged one by one, the driving block is connected to the corresponding connecting rope, the driving block slides and connects to the side wall of the door and window frame with the winding of the connecting rope; the reset spring is connected between the corresponding second protrusion and the door and window frame, the extension direction of the reset spring is parallel to the sliding direction of the second protrusion, and when the reset spring is not deformed, the second protrusion is located on the sliding path of the driving block, and one end of the driving block and the second protrusion close to each other is provided with a relief surface for pushing the second protrusion by the driving block, so that the second protrusion slides towards the direction close to the through hole and pushes the sealing strip into the through hole.

[0014] When the driving rod is rotated, the connecting rope is gradually separated from the rotating rod and wound on the driving rod, at this time, the rotating rod is rotated to make the first protrusion turn to the position facing the sealing strip and press the sealing strip against the glass side wall; at the same time, the driving block slides relative to the door and window frame under the pulling of the connecting rope and pushes the second protrusion in the sliding process to make the second protrusion move towards the direction close to the through hole and push the sealing strip into the through hole.

[0021] Preferably, the transition piece is elastically deformable, the door and window frame side wall is provided with a limiting groove for the insertion of the transition piece, and the part of the transition piece for contacting the first protrusion is located in the middle of the transition piece.

[0022] By adopting the above technical scheme, the limiting groove is arranged and the material of the elastically deformable transition piece is limited, so that the transition piece can support the rotation of the rotating rod and extrude the sealing strip, and the fixed connection between the transition piece and the door and window frame is realized.
