[0002] Interior doors are the doors leading to bedrooms or studies, used to divide interior spaces, enhance security, and beautify the interior. For example... Figure 1 As shown, the existing interior door frame includes a side frame and a top frame. There are two side frames, which are located on the left and right sides of the top frame. The top frame includes a main frame and face frames located on both sides of the main frame. The main frame is provided with a slot, and the face frames are provided with a block. The block is inserted into the slot and then glued to the wall with adhesive to fix the face frame to the main frame. When the adhesive fails, the face frame is subjected to the force generated by the door opening and closing during use. The direction of this force is the same as the insertion direction of the block, which can easily cause the block to come out of the slot, causing the face frame to fall off. This results in frequent maintenance and also poses a safety hazard. Utility Model Content

[0003] Therefore, it is necessary to provide an interior door that prevents the connector from falling off when the glue fails, as the frame is subjected to the force of the door opening and closing.
