Description

Technical Field

[0001] The utility model relates to the technical field of hardware doors and windows, and in particular to a double-leaf split door structure. Background Art

[0002] At present, in building doors and windows, when the door opening is wide, it is designed as a double-leaf door for the convenience of opening and aesthetics. The door leaf of the existing double-leaf door is generally composed of a leaf frame and a glass panel. The leaf frame is mainly composed of an upper frame member, a lower frame member, a left frame member and a right frame member with the same profile structure to form a rectangular frame structure. However, due to the large stress on the lower frame member, it is easy to deform, resulting in poor sealing. In the process of opening or closing the door leaf, the trolley, wheelchair, baby carriage used by the user or the objects placed on the ground are easy to collide with the glass panel, resulting in cracks and damage, which has certain limitations. Utility Model Content

[0006] As a further improvement of the above technical solution:

[0007] A first installation notch is provided on the lower side of the first profile, the upper side of the second profile, and the inner side opposite to the third profile, a door pressure line is clamped and connected in the first installation notch, and a first rubber strip is provided on the door pressure line;

[0008] The lower side of the first plate, the upper side of the second plate, and the relatively inner side of the third plate are all provided with extension parts, and the second adhesive strip is arranged on the extension part, and the glass is installed between the first adhesive strip and the second adhesive strip.

[0009] A second installation slot is provided on one side of the third profile away from the first installation slot.

[0010] The door frame comprises an upper door frame, a lower door frame and a vertical door frame. The upper door frame and the vertical door frame have the same structure and both comprise a first door frame profile, a second door frame profile and a first door frame heat insulation strip connected between the first door frame profile and the second door frame profile.

[0011] A third installation slot is extended from the inner side of the first door frame profile.

[0012] The lower door frame includes a third door frame profile, a fourth door frame profile, and a second door frame heat insulation strip connected between the third door frame profile and the fourth door frame profile.
