Door and window sliding support

Abstract

The invention discloses a door and window sliding support. The door and window sliding support comprises a sliding groove (1) and a first connection rod (2). The door and window sliding support is characterized in that the interior of the sliding groove (1) is fixedly connected with a second connection rod (3) and a third connection rod (4), the interior of the sliding groove (1) is movably connected with a fourth connection rod (5), the tail end of the second connection rod (3) and the tail end of the fourth connection rod (5) are connected with the first connection rod (2) respectively, the starting end of the fourth connection rod (5) is connected with a sliding piece (7), and the tail end of the third connection rod (4) is connected with the fourth connection rod (5). The door and window sliding support is capable of enabling a window sash to be opened and closed flexibly, and has no potential safety hazard.

Description

technical field [0001] The invention relates to a spare part of a door and window, in particular to a sliding brace of a door and window. Background technique [0002] At present, building energy saving and consumption reduction work has become an important part of my country's sustainable development strategy. Building doors, windows and curtain walls, as the weak links of building envelope structure energy saving, have become the most concerned focus of building energy saving. According to relevant statistics: more than 50% of the heating and cooling energy consumption of the building envelope is caused by the loss of doors, windows and curtain walls. Therefore, how doors and windows meet the requirements of building energy conservation has become the key. This requires that the external doors and windows have better airtight and watertight performance, but when subjected to negative wind pressure, the wind load will be mainly borne by the hardware. Become the key factor ...

AI Technical Summary

Problems solved by technology

In the case of strong wind, the window sash is often blown off under the action of negative wind pressure, which has the hidden danger of accidental injury. Only sliding braces can be used for the load-bearing parts of outward-opening doors and windows, and hinges (hinges) cannot be used. However, the traditional sliding Due to structural reasons and the difference in the transmission principle of the crank-link mechanism, the window sash is easy to sag, and the opening is not flexible, and even causes the window sash to fall, causing huge losses.
