Self-control positioning rewinding screen window

Abstract

A self-control positioning rewinding screen window comprises a housing device, a reel screen window device, a window frame device and a positioning pull rod device, wherein the window frame device comprises side pillars and a bottom rod, and slideways are disposed in the side pillars; the positioning pull rod device comprises a pull rod, and an outer clamping heads are disposed on end parts of the pull rod; the positioning pull rod device also comprises inner clamping heads and a screw rod, the screw rod successively passes through the inner clamping head and the outer clamping heads and reaches inside of the pull rod, the screw rod is equipped with spring stopping blocks on the outer sides of the outer clamping heads, the spring stopping blocks are clamped inside the pull rod, the screw rod is sleeved by springs between the spring stopping blocks and the outer clamping heads, and the screw rod is equipped with bolts embedded in the spring stopping blocks are disposed on outer sides of the spring stopping blocks; and the inner clamping heads are located in the slideways of the window frame device, the outer clamping heads are disposed outside the slideways, and the outer clamping heads and the inner clamping heads generate clamping force to the side pillars. The screen window provided by the invention has the advantages that a screen mesh can be positioned and unfolded at any position in the window frame; rewinding inertia force of the rewinding screen window is small; the structure is simple; and installation and disassembly are convenient, etc.

Description

technical field [0001] The invention relates to a rewinding screen window, in particular to a self-control positioning rewinding screen window, which belongs to the field of screen window and screen door manufacturing. Background technique [0002] In household life, in order to prevent mosquitoes from invading the living room, people often install screens on doors and windows to prevent mosquitoes from invading. Most of the current screen windows in the market use the screen window shaft tube fixed in the casing through the central axis, use the pull rod at the lower end of the screen window to pull out the screen net, and use the elastic parts in the screen window shaft tube to pull back the unfolded screen window After being rolled up, the gauze is fully unfolded through the cooperation of the fixing parts arranged on the pull rods and the corresponding fixing parts arranged on the window sill. The rewinding screen window with this structure can only realize two working ...

AI Technical Summary

Problems solved by technology

However, the structure of the screen window with this structure is complicated, and installation and disassembly are troublesome; the positioning function is realized by the friction force between the pull rope and the pull rod, but the friction force between the pull rope and the pull rod is difficult to control. The wear of the friction parts leads to the loosening of the pull cord, which leads to the inability of the gauze to be positioned well in individual positions in the window frame, and even no longer has the function of positioning
