Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fastener technology, specifically relating to a nail-free fastener for a window screen frame. Background Technology
[0002] The screen frame is the main supporting structure of the screen window, used to fix the screen and ensure the stability and durability of the screen window. The current installation method of screen window frames requires drilling holes in the screen frame in advance, aligning the screen frame with the window frame, and screwing the screen frame and window frame together. This results in a complicated installation process that wastes labor and time. Utility Model Content
[0003] Solve the technical problem of inconvenient installation of existing screen window frames.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a nail-free fixing component for a screen frame, comprising an inner shell and an outer shell. The outer shell is fitted around one end of the inner shell, and the mounting portion at the other end of the inner shell is located outside the outer shell. The outer shell contains an adjustment portion, a buckle, a hook, and a bolt. The bottom wall of the adjustment portion has a locking groove, and the buckle is located in the locking groove. One end of the hook is located on the upper surface of the buckle, and the other end extends to the outside of the fixing component. One end of the bolt passes through the outer shell and the hook and connects to the buckle. By rotating the bolt, the hook can be moved up and down in the adjustment portion, thereby adjusting the installation distance between the hook and the screen frame.
[0005] Furthermore, the inner shell has mounting grooves on both sides of its sidewalls, and each mounting groove has a flap.
[0006] Furthermore, the flaps are made of metal.
[0007] Furthermore, the bolt is a Phillips head bolt.
[0008] The present invention has the following advantages: the mounting part of the inner shell is fixedly connected to the window frame by fasteners, and the hook on the side of the inner shell is fastened to the screen frame, so that the screen frame can be installed without nails, making the operation simpler and more convenient. Before the factory ships the goods, the inner shell and the screen frame are nailed and fixed before packaging and shipping. Individual buyers who want to install screens can directly adjust the bolts to tighten them and easily install screens. Attached Figure Description

[0011] like Figures 1 to 5 As shown, a nail-free fixing component for a screen frame includes an inner shell 10 and an outer shell 20. The outer shell 20 is fitted onto the outer side of one end of the inner shell 10, and the mounting part 11 at the other end of the inner shell 10 is located outside the outer shell 20. The outer shell 20 is provided with an adjustment part 30, a buckle 40, a hook 50, and a cross bolt 60. The bottom wall of the adjustment part 30 is provided with a locking groove 31, and the buckle 40 is located in the locking groove 31. One end of the hook 50 is located on the upper surface of the buckle 40, and the other end extends to the outside of the fixing component. One end of the bolt 60 passes through the outer shell 20 and the hook 50 and is connected to the buckle 40. By rotating the bolt 60, the hook 50 can be moved up and down in the adjustment part 30, thereby adjusting the installation distance between the hook 50 and the screen frame.
[0012] In use, the mounting part 11 of the inner shell 10 is fixedly installed to the window frame by fasteners. The inner shell 10 and the hook 50 on the side form a snap-fit space 12 for the screen window frame. The screen window frame is placed in the snap-fit space 12 to complete the fixed installation of the screen window frame. By rotating the bolt 60, the distance between the hook 50 and the inner shell 10 can be adjusted, so that the position of the hook can be adjusted according to the installation position of the screen window frame.
[0013] The inner shell 10 has mounting grooves on both sides of its side walls. Each mounting groove has a metal flap 13. When in use, the metal flap 13 in the inner shell 10 can increase the strength and make the structure more stable and less prone to deformation.
[0014] In summary, the nail-free fixing component for the screen window frame of this utility model has an inner shell 10 with a mounting part 11 fixedly connected to the window frame by fasteners, and a hook 50 on the side of the inner shell fastening to the screen window frame, which enables nail-free installation of the screen window frame and makes the operation simpler and more convenient.
