Connecting rod device for multifunctional security window

Abstract

The invention discloses a connecting rod device for a multifunctional security window. The technical scheme adopted by the invention has the main points that the connecting rod device for the multifunctional security window comprises a connecting rod and hinges. Two opposite faces on a rectangular square tube of the connecting rod respectively extend outwards along the same direction and are respectively bent inwards for 90 degrees to form bayonets; each hinge respectively comprises a right-angle side A and a right-angle side B; the cross-section shape of each right-angle side A is matched with the inner hole of each bayonet of the connecting rod; the tail end of each right-angle side B is connected with a pin hole; two grooves are respectively arranged at joint of each right-angle side B and each right-angle side A; the depth of each groove is consistent with the height of the boss of the corresponding bayonet of the connecting rod; and the respective right-angle sides A of the hinges are respectively inserted into the bayonets of the connecting rod and are respectively and in sliding fit with the bayonets of the connecting rod. According to the connecting rod device for the multifunctional security window, gaps of multiple sashes are consistent and are in tight and reasonable fit, so that the multifunctional security window not only is attractive but also is capable of better resisting wind and water.

Description

technical field [0001] The invention relates to a connecting rod device of a blind, in particular to a multifunctional anti-theft window connecting rod device in which the relative positions of connecting rod holes of a plurality of sashes can be adjusted at will.
