[0027] As an implementation, the frame main body 10 includes an upper frame 11 , a lower frame 12 , a left frame 13 and a right frame 14 . The upper attachment frame 11, the left attachment frame 13, the lower attachment frame 12 and the right attachment frame 14 are sequentially connected end to end by the connector 20 to form a rectangular attachment frame main body 10, and the upper attachment frame 11, the lower attachment frame 12, The space defined by the left auxiliary frame 13 and the right auxiliary frame 14 forms the installation space of the door and window, and the installation surface is set towards the installation space of the door and window.
[0028] Wherein, the connecting piece 20 is used to realize the connection of adjacent subframes. Specifically, both ends of the connector 20 have insertion ends, and the insertion ends at both ends are arranged vertically, and are respectively inserted into two adjacent sub-frames. In order to realize the plug-in instal...

The invention provides a door and window installation self-locking device. The door and window installation self-locking device comprises an attachment frame body, a locking plate and a sliding block. The attachment frame body is installed in a wall and provided with an installation face and a wall attachment face back on to the installation face, and an installation sliding groove is formed in the installation face. The locking plate is installed at the edge of a door and window and can be fixedly installed on a frame of the door and window, the locking plate is provided with a U-shaped locking groove located in the sliding locus of the sliding block, and the U-shaped locking groove is opened towards the sliding block. The sliding block is arranged in the installation sliding groove in a sliding mode, the section of the sliding block is in an I shape, the sliding block can slide relative to the locking plate, and when sliding to the U-shaped locking groove along the sliding locus, the sliding block can be locked with the locking plate in cooperation of the U-shaped locking groove. By means of the door and window installation self-locking device, the door and window can be rapidly installed, and efficiency is high; besides, the door and window installation self-locking device is low in cost, and thus wide application is facilitated.
Description
technical field [0001] The invention relates to a door and window installation device, in particular to a self-locking device for door and window installation. Background technique [0002] At present, in the installation of building doors and windows, it is necessary to install the doors and windows into the wall by using the attached frame frame, and then install the form. In this way, the cycle is longer and the workload is heavy. In addition, in the installation of doors and windows, the attached frame can also be installed on the wall first, and then the attached frame can be nailed to fix and connect the window frame. However, this method is not suitable for the attached frame made of plastic, which is prone to breakage, has potential safety hazards, and is costly. Moreover, if an aluminum alloy is used, the cost is high and the installation strength is high. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution.
