Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, and more specifically, to a connection structure and a door and window. Background Art

[0002] In the door and window manufacturing industry, especially when making French doors, it is often necessary to make double doors. When making double doors, a false mullion must be used. Since the false mullion is fixed to one side of the door leaf, when the door leaf is opened, the false mullion will move with the door leaf. When both door leaves are opened simultaneously, the middle of the doorway is empty without a conventional mullion, which is convenient for people to enter. However, with the progress of technology and the continuous expansion of application scenarios, the traditional fixed-size false mullion gradually reveals its limitations.

[0003] When the size of the door leaf changes, if the size of the conventional false mullion is fixed and non-adjustable, then there will indeed be a problem of re-opening the mold for production. This situation is not only time-consuming and laborious but also increases additional economic costs, which may not be ideal for customers. Summary of the Utility Model

[0004] Based on this, in order to solve the problem that the existing false mullion has a fixed size and is non-adjustable, the utility model provides a connection structure and a door and window, and its specific technical solutions are as follows:

[0005] A connection structure for a door and window, comprising:

[0008] A fixing member for fixing the position where the inserting portion is inserted into the plugging portion.

[0009] For the above connection structure, by adjusting the position where the inserting portion is inserted into the plugging portion, the entire connection structure can be adapted to the change in the size of the door leaf, and it can be easily matched with the door leaf without re-opening the mold for production, thereby saving time, labor, and cost and improving production efficiency.

[0010] Furthermore, the first connecting member is a profile member provided with a plugging groove; the second connecting member is a profile member provided with inserting flanges, the inserting flanges being two flanges arranged in parallel, and the distance between the two flanges being adapted to the groove width of the plugging groove.

[0011] Further, the fixing member is a self-tapping screw, which sequentially passes through the insertion slot, the insertion flange, and the second door leaf.

[0012] On the other hand, a door and window includes a first door leaf, a second door leaf, and a connection structure.

[0013] Further, the first connection portion includes a clamping flange that clamps with the second door leaf; the second connecting member is integrally in a T-shaped structure, and the second connection portion is a limiting flange provided at the top of the T-shaped structure; the second door leaf is provided with a clamping groove adapted to the clamping flange and a limiting groove adapted to the limiting flange.

[0014] Further, the fixing member is a self-tapping screw, and the second door leaf is provided with a mounting wall adapted to the self-tapping screw.

[0015] Further, a window lock unit is further included; the window lock unit includes a lock body provided on the first door leaf and a lock seat provided on the first connecting member; the first connecting member is provided with a mounting groove for mounting the lock seat.

[0016] Further, a sealing strip is provided at the other end of the top surface of the T-shaped structure relative to the limiting flange; the first door leaf is provided with a sealing groove adapted to the sealing strip and a contact strip adapted to the mounting groove.

[0017] Further, the window lock unit further includes a square shaft connected to the lock body and a handle rotatably connected to the square shaft; the handle is provided on the first door leaf.

[0018] Further, the top surface of the T-shaped structure is coplanar with the fan surfaces of the first door leaf and the second door leaf. Description of the Drawings
