[0002] Doors and windows are components of buildings. They are divided into enclosing components or partition components according to their location. They have different design requirements and have functions such as thermal insulation, heat insulation, sound insulation, waterproofing and fire prevention. Most of them are made of aluminum alloy and are widely used in the field of construction engineering. In home decoration, aluminum alloy doors and windows are often used to enclose balconies.
[0003] In real life, the existing doors and windows have poor sealing performance when in use. Most of them are fixed with sealing strips at the contact points between the upper and lower window bodies and the inner side of the window frame to isolate the slide from the outside world and achieve a sealing effect. However, there are many gaps in the sealing strips, and the sealing effect is relatively general. Frequent pushing and pulling of doors and windows can easily cause friction and wear of the sealing strips at the upper and lower ends of the window body, thereby affecting the sealing effect of the doors and windows.

[0009] As a preferred embodiment, a lock is provided between the two windows, and glass sheets are embedded in the inner walls of the two windows.
[0010] As a preferred embodiment, a spring is sleeved on the outer wall of the connecting rod, one end of the spring is fixedly connected to one side of the rod seat, and the other end of the spring is fixedly connected to one side of the pull block.
[0011] As a preferred embodiment, two sides of the outer wall of the connecting rod respectively penetrate one side of the rod seat and one side of the window body.
[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:
[0013] The door and window with good sealing performance benefits from the design of the twisting wheel, the bidirectional screw rod, the first sealing strip and the sealing gasket. The twisting wheel drives the two first sealing strips to move in opposite directions through the bidirectional screw rod so that the two first sealing strips are stored in the window frame. In this way, friction and wear of the first sealing strips can be avoided, thereby not affecting the sealing effect of the door and window. At the same time, when the door and window are closed, the first sealing strip cooperates with the sealing gasket to increase the sealing performance between the window body and the window frame, thereby improving the overall sealing effect of the door and window.
[0014] By providing an elastic block, a spring, a pull block and a second sealing strip, after the door and window are closed, the elastic block is pressed downward, and the pull block is driven to move inward under the elastic action of the spring, and then the second sealing strip is driven to move outward through the connecting rod so that it is engaged with one side of the other window. This can increase the sealing between the two windows, thereby further increasing the sealing effect of the door and window. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] How it works
[0034] When the sliding window 2 is opened, the knob 4 is rotated, and the knob 4 drives the two first connecting blocks 5 to move in opposite directions through the bidirectional screw rod 3, thereby driving the two first sealing strips 6 to move in opposite directions until the first sealing strips 6 are stored in the window frame 1. This can avoid friction and wear on the first sealing strips 6 and affect the sealing effect of the door and window. When the window 2 is closed, the knob 4 is rotated in the opposite direction. At this time, the knob 4 rotates and drives the two first sealing strips 6 to move toward each other until the first sealing strips 6 are in contact with the inner wall of the window 1. Under the action of the sealing gasket 7, the sealing between the window 2 and the window frame 1 can be increased. At the same time, when the window 2 is closed, the elastic block 11 is pressed downward. At this time, the pull block 14 is driven to move inward under the elastic action of the spring 13. The pull block 14 drives the second sealing strip 15 to move through the connecting rod 12, so that it is engaged with the other window 2. This can increase the sealing between the two windows 2, thereby further increasing the sealing effect of the door and window.
