a safety window

Abstract

The invention relates to a safety protection window which comprises a window frame, as well as a first window sash and a second window sash which are arranged in the window frame, wherein one side, which is far away from the second window sash, of the first window sash is hinged to the window frame; at least one connecting rod is hinged to each of the upper side and the lower side of the second window sash; the other end of each connecting rod is hinged to the upper side or the lower side of the corresponding window frame; a push rod capable of pulling the second window sash to move laterally when the first window sash rotates is connected between the first window sash and the second window sash; the first end of the push rod is hinged to the upper side or the lower side of the first window sash, and the second end of the push rod is hinged to the upper side or the lower side of the corresponding second window sash; the safety protection window is characterized in that when the first window sash and the second window sash are closed, the two hinge points of the push rod generate a height difference in the direction perpendicular to the front end face of the window frame. The safety protection window has the advantages that the window sashes can be opened in a power-saving manner, and the structure is reasonable.

Description

technical field [0001] The invention relates to a safety protection window. Background technique [0002] Chinese patent CN201220365996.2 discloses a safety protection window. The structure of this window can achieve better safety performance. It relies on the translation of the second sash 3 to fill the gap formed after the first sash 2 is opened. The gap is too large, and the purpose of sealing is good in the closed state, but at least some technical problems have not been solved well, and the specific expressions are as follows: [0003] First, from attached figure 1 It can be seen from the figure that when the sash is close to or closed, that is, when the connecting rod is in a fully retracted state, the pull rod 5 is parallel to the front end of the sash, so that the direction of the force is almost perpendicular to the pull rod when the sash is opened. It takes a lot of thrust to push the sash open, which also causes the hinged position of the pull rod 5 to be easily...

Problems solved by technology

[0002] Chinese patent CN201220365996.2 discloses a safety protection window. The structure of this window can achieve better safety performance, relying on the translation of the second sash 3 to fill the second sash A part of the gap is formed after the sash 2 is opened, and no excessive gap will be left in the open state, and the purpose of good sealing performance in the closed state, but at least there are technical problems that have not been well resolved, and the specific expressions are as follows:

[0003] First, from attached figure 1 It can be seen from the figure that when the sash is close to or closed, that is, when the connecting rod is in a fully retracted state, the pull rod 5 is parallel to the front end of the sash, so that the direction of the force is almost perpendicular to the pull rod when the sash is opened. It takes a lot of thrust to push the sash open, which also causes the hinged position of the pull rod 5 to be easily damaged

[0004] Second, from figure 1 And attached figure 2 It can be seen from the figure that in order to facilitate the movement of the second sash 3 by the pull rod, the connecting rod 4 is arranged obliquely relative to the window frame. The rotation angles of the sash 2 and the connecting rod 4 are consistent. When the connecting rod 4 rotates to be perpendicular to the window frame, the rotation angle of the first sash 2 is also less than 90 degrees, which leads to an unsatisfactory movement range of the second sash 3

[0005] Third, because the second sash 3 is opened in translation, the opening range of the entire window depends on the size of the first sash 2 at first, because the two ends of the pull rod 5 are respectively Pivoted on the frames of the first sash 2 and the second sash 3, when the first sash 2 with a larger size is selected, the pull rod 5 also becomes longer. Cannot be set at a slant, exacerbating the problem described in the first point, in addition, pulling the lever 5 when opening the sash is also more prone to deformation, twisting
