Locking plate type pull cord tightness adjustment device for honeycomb blinds

Abstract

The invention discloses a locking plate type pull cord tightness adjustment device for honeycomb blinds. The locking plate type pull cord tightness adjustment device is provided with a lower rail of the honeycomb blinds. A left guiding rib and a right guiding rib is arranged on the inner wall of the lower rail. An opening is formed between the left guiding rib and the right guiding rib. Locking plates are arranged between the left guiding rib and the right guiding rib, wherein the locking plates are made of metal. The width S1 of each locking plate is greater than the width S2 of the opening.The thickness T1 of each locking plate is greater than 1mm. Clamping grooves are formed in the two sides of each locking plate. The clamping grooves are matched with the left guiding rib and the rightguiding rib. A cord hole is formed above the middle of each locking plate. The locking plate type pull cord tightness adjustment device has the beneficial effects that the locking plates are simple in structure and convenient to produce, and the product cost is low; the thickness of each locking plate is greater than 1mm, then, the thickness of each clamping groove can be greater than 1mm, and when the clamping grooves are inclined, it can be guaranteed that the clamping grooves can be tightly clamped with the left guiding rib and the right guiding rib; and the locking plates are made of themetal material, on one hand, the structural strength is high, on the other hand, when the locking plates are matched with the left guiding rib and the right guiding rib, the metal material is clampedmore reliably, sliding cannot be caused, and the locking plate type pull cord tightness adjustment device is not prone to abrasion and long in service life.

Description

Technical field [0001] The invention relates to a guide wire of a honeycomb curtain, in particular to a lock piece type wire tension adjusting device of the honeycomb curtain. Background technique [0002] The honeycomb curtain is mainly composed of side rails, upper and lower rails, moving rails and curtain bodies. The side rails and the upper and lower rails are fixedly connected by connecting pieces. One end of the curtain body is fixed with the upper rail or the lower rail, and the other end of the curtain body Connect the moving rail, the moving rail slides up and down along the side rail. A pull wire is usually set in the side rail. The pull wire passes through the moving rail and the curtain body to guide and position the moving rail and the curtain body to move up and down to prevent movement. When the track and the curtain body move, they are offset. The wire in the prior art honeycomb curtain is usually tightened by a stud. By making a screw hole in the box cover, the ...

AI Technical Summary

Problems solved by technology

The backguys in the prior art honeycomb curtains are usually tightened by studs. Screw holes are formed in the box cover, and the studs are screwed into the screw holes. The head of the backguy is manually wound on the outer wall of the stud to make the backguy Tighten the stud, then tighten the stud down with tools such as a screwdriver, and the ring at the upper end of the stud will press and fix the stay wire. Pull wires and studs are easy to loose, and the tensioning reliability is poor

Therefore, someone has applied for the Chinese utility model patent 201820934979.3, the patent name is "a sunshade sunroof with convenient adjustment of the pull cord", which includes a window frame and a mesh cloth. The window frame is composed of an upper rail, a lower rail, a left rail, a right rail The connecting parts of the above-mentioned rails are composed of a middle rail connected to each of the upper rail and the lower rail by a sliding connection, and a middle rail is connected between the two middle rails, and a wire buckle is provided on the middle rail. A rack is plugged in, and a wire buckle is provided on the rack, the mesh is connected between the middle rail and the rack, a rack is provided on the left rail, and a dial is movably connected to the rack. Tightening rod, one end of an adjusting rope is fixed on the wire buckle, and the other end of the adjusting rope passes through the mesh cloth, the wire buckle, the mid-range, the connecting piece and is fixed with the said tightening rod in turn. This structure is mainly composed of teeth The rod is matched with the tightening lever to adjust the pull cord. On the one hand, the patent does not introduce the specific structure of the rack and the tightening lever. After pulling the force, the tension lever will act on the rack, which will easily pull the rack upwards, causing the rack to arch in an arc, causing the rack to deform or even break, and the service life is short
