a wind brace

Abstract

The invention discloses a positioning wind brace which comprises a wind brace positioning assembly and a connection rod assembly, wherein the connection rod assembly comprises a connection rod and a sliding piece; the wind brace positioning assembly comprises a sliding rail on which the sliding piece slides, a handheld transmission piece matched with the sliding rail in a sliding manner and an extrusion piece; when the handheld transmission piece forwards slides along the sliding rail, the extrusion piece upwards moves, so that the sliding piece and the sliding rail are closely extruded; at the moment, the sliding piece stops sliding, and a window sash angle is fixed; when the handheld transmission piece backwards slides along the sliding rail, the extrusion piece downwards moves, and the sliding piece and the sliding rail are separated; at the moment, the sliding piece can continuously slide, and the window sash angle can be adjusted. Due to the structural design, by transmission of the handheld transmission piece, the extrusion piece extrudes the sliding piece tightly; therefore, positioning of a window sash is realized; furthermore, the phenomenon that the positioning wind brace is broken because the window sash is locked after being positioned can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of wind braces, in particular to a positioning wind brace. Background technique [0002] In the prior art, the positioning of wind braces generally adopts the positioning method of racks meshing with each other, such as Figure 8 As shown, that is, when the transmission plate 121 slides back and forth, the protrusion arranged on the transmission plate 121 interferes with the circular convex point at the bottom of the lower rack 10, so that the lower rack 10 moves upward and connects with the upper rack at one end of the connecting rod 21. 9 are engaged with each other, and then the window sash connected with the other end of the connecting rod 21 is positioned; as Figure 9 As shown, when the protrusion on the transmission plate 121 is separated from the circular convex point at the bottom of the lower rack 10, the lower rack 10 moves downward and separates from the upper rack 9 at one end of the connecting ...

[0002] In the prior art, the positioning of wind braces generally adopts the positioning method of racks meshing with each other, such as Figure 8 As shown, that is, when the transmission plate 121 slides back and forth, the protrusion arranged on the transmission plate 121 interferes with the circular convex point at the bottom of the lower rack 10, so that the lower rack 10 moves upward and connects with the upper rack at one end of the connecting rod 21. 9 are engaged with each other, thereby making the window sash connected with the other end of the connecting rod 21 positioned; as Figure 9 As shown, when the protrusion on the transmission plate 121 is separated from the circular convex point at the bottom of the lower rack 10, the lower rack 10 moves downward and separates from the upper rack 9 at one end of the connecting rod 21, thereby making the connection with the connecting rod 21 The window sash connected at the other end can be adjusted freely. The positioning wind bracing of the above structural design has a relatively thick positioning wind bracing after assembly, such as Figure 10 As shown, when matching with the standard window sash C slot 71, it is necessary to destroy the bottom surface of the C slot before assembling. The positioning wind brace installed in this way greatly reduces the overall strength of the window sash; The positioning method of meshing with each other makes the window sash in a locked state after positioning, that is, when the window sash is blown by strong wind, it is difficult to be automatically closed by strong wind, so it is easy to cause damage to the positioning wind brace
