Both ends of the retractable frame body are provided with connecting fasteners and end fixing plates. An insert block is integrally formed below the connecting fastener and inserted into the side fastening frame of the retractable screen window. An elastic fastening head is integrally formed on the insert block, and a limiting protrusion is integrally formed on the elastic fastening head to elastically engage with the fastening slot on the side fastening frame of the retractable screen window. Horizontal and vertical reinforcing ribs are formed on one side of both the end fixing plate and the connecting fastener. An inlet clearance groove is formed on one side of the reinforcing rib on both the end fixing plate and the connecting fastener. A pressing limiting groove is formed on the end fixing plate, and a limiting protrusion is integrally formed on the connecting fastener to press against the pressing limiting groove.
[0006] As a further embodiment of this utility model: a wheel axle mounting groove is provided on one side of the reinforcing rib on the connecting fastener, a gear shaft is movably arranged inside the wheel axle mounting groove, and a fastening gear is fixedly connected to the gear shaft.
[0007] As a further embodiment of this utility model: an elastic fastener is fixedly installed on the connecting fastener on one side of the fastening gear, and a fastening tooth that mates with the groove of the fastening gear is integrally formed below the elastic fastener.
[0008] As a further embodiment of this utility model: the bottom fastening frame and the side fastening frame of the rolling screen window are connected by a bottom connecting fastener. The bottom connecting fastener includes an extended support portion integrally formed on the top of the bottom connecting fastener that cooperates with the side fastening frame of the rolling screen window. An elastic buckle head integrally formed on the extended support portion that cooperates with the fastening slot on the side fastening frame of the rolling screen window. A bottom insertion portion integrally formed on one side wall of the bottom connecting fastener that inserts into the bottom fastening frame. Expansion portions integrally formed on both sides of the bottom insertion portion.
[0009] As a further embodiment of this utility model: the bottom of the limiting protrusion of the connecting fastener is integrally formed with a guide angle.
[0010] As a further embodiment of this utility model: a handle frame for fixing the rolled-up screen is movably provided between the side fastening frames of the screen window.
[0011] This utility model allows the elastic fastening head of the connecting fastener to be inserted into the side fastening frame of the roll-up screen window. The connection between the side fastening frame and the roll-up screen window frame is achieved through the engagement with the fastening slot. Disassembly is simple; just press the elastic fastening head to remove it, facilitating cleaning. Furthermore, the horizontal and vertical reinforcing ribs formed on the end fixing plate and connecting fastener significantly enhance the connection strength of this fastener. The guide opening allows the screen box to be guided into the correct position for fastening even without precise alignment during assembly. The pressing and limiting grooves and protrusions work together to securely fasten the end fixing plate and connecting fastener, preventing improper disassembly or drop during use.
[0012] This utility model can achieve elastic limiting of the engaging gear by cooperating with the elastic fastener, and optimize the cable adjustment structure by changing the original turbine with worm gear structure to an engaging gear and elastic fastener structure. The optimized structure is more convenient to adjust and assemble, and the traction line is led out from the cable outlet to prevent the gear rod from being pulled off during assembly.
[0013] This utility model allows for the insertion of the extended support portion on the bottom connecting fastener into the side fastening frame of the roller screen window. The elastic buckle head engages with the fastening slot to achieve locking. The bottom plug portion is then inserted into the bottom fastening frame, and the tightening portion achieves a tightening connection. This makes installation and disassembly extremely efficient and easy to clean. Attached Figure Description
