Description

Technical Field

[0001] The utility model relates to the field of door and window locking, and more specifically, to a door and window locking structure with high sealing performance. Background Art

[0002] Doors and windows are divided into enclosure components or partition components according to their location. They have different design requirements and must have functions such as heat preservation, thermal insulation, sound insulation, waterproofing, and fire prevention. New requirements are energy saving. In cold areas, the heat lost through the gaps in doors and windows accounts for about 25% of the total heating heat consumption. Doors and windows usually have movable frames and fixed frames that are movably connected by hinges. Then sealing strips are installed on the fixed frames and movable frames, or components with effects such as thermal insulation and waterproofing are provided to improve the high sealing of the overall door leaf, making the door leaf more practical. However, the fixed frames and movable frames are generally locked by locking structures. After the processing plant processes the fixed frames and movable frames, the fixed frames and movable frames produce slight errors, which results in the locking structure being unable to completely lock the door leaf after the fixed frames and movable frames are installed, resulting in a reduction in the high sealing of the door leaf.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present utility model is to provide a door and window locking structure with high sealing performance. By arranging slidably adjustable clamping plates on two C-shaped locking plates, the C-shaped locking plates can be adjusted according to the errors between the fixed frame and the movable frame of the door leaf after installation, thereby achieving the effect of locking the door leaf and increasing the sealing performance of the door leaf.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a highly sealed door and window locking structure, comprising a mounting plate arranged on a movable frame of a door and window, two locking rods being slidably arranged on the mounting plate, the sliding trajectories of the two locking rods being parallel to each other, C-shaped locking plates corresponding to the locking rods being arranged at both ends of the mounting plate, and pressure plates being slidably arranged on the two C-shaped locking plates, and the sliding direction of the pressure plates being perpendicular to the sliding direction of the locking rods.

[0006] Preferably, an inclined limiting surface is provided at the end of the locking rod close to the C-shaped locking plate.

[0007] Preferably, a rotating handle is provided on the mounting plate, a driving gear is provided on the handle, and the two locking rods are provided with driven racks meshing with the driving gear, and the two locking rods are respectively provided on both sides of the driving gear.
