Abstract
The invention provides a lower opening-closing mechanism for a casement and sliding door and window to solve the following problems: when the window is opened, the sashes move out of the window frames and the weight of the whole sashes are independently borne by rockers; and the rockers will be deformed due to long-time bearing, thus affecting the reliability of the opening-closing mechanism. The lower opening-closing mechanism is characterized in that the lower opening-closing mechanism comprises a sash shaft, a rocker and a support shaft, wherein a raised support point is arranged between the middle point of the rocker and the support shaft; and the support point pushes against a lower frame of the sash. The lower opening-closing mechanism has the following beneficial effects: the weight borne by the rocker is greatly lightened, thus avoiding deformation of the rocker due to weight bearing and greatly improving the service life and reliability of the opening-closing mechanism.
Description
Technical field
The present invention relates to a kind of flat lower open-and-close mechanism of slide door or window of opening.
Background technology
CN201443272U discloses a kind of flat slide door or window open-and-close mechanism and flat slide door or window of opening opened.This door and window (hereinafter referred to as window) has been concentrated the advantage of casement window and sliding sash, and while having realized pass window, sealing effectiveness is equal to casement window, is equal to sliding sash, does not account for the effect of the interior space while windowing.It is because used open-and-close mechanism that this window is realized above-mentioned effect.Open-and-close mechanism mainly comprises base plate 30, sash axle 31, rocking bar 34, back shaft 32 etc.At two open-and-close mechanisms of upper and lower each installation of sash, back shaft slides in the slideway of window frame.In the time closing window, whole sash enters window frame, and the weight of sash is mainly carried by window frame lower frame; In the time windowing, whole sash capable of parallel moving goes out window frame lower frame, and the weight of whole sash is mainly carried by the rocking bar in lower open-and-close mechanism.Long-time bearing, rocking bar can deform, and affects the reliability of open-and-close mechanism, and particularly, in the time that sash is double-layer glass or even triplex glass, situation is more so.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of flat lower open-and-close mechanism of slide door or window of opening.
The object of the present invention is achieved like this: it comprises sash axle, rocking bar and back shaft, it is characterized in that: between the mid point (referring to the mid point between back shaft and sash axle) of rocking bar and back shaft, establish the strong point (stress point) of a projection, this strong point withstands on the lower frame of sash.At this moment rocking bar is as lever, and back shaft is as the fulcrum of this lever, and the present invention utilizes lever principle, and most of weight of sash is passed through to strong point off-load to back shaft.
Compared with prior art, the invention has the beneficial effects as follows: greatly alleviated the weight of rocking bar carrying, avoided being out of shape because of rocking bar load-bearing, greatly improved application life and the reliability of open-and-close mechanism.
Accompanying drawing explanation
Further illustrate the present invention below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram that the present invention is applied in sash lower frame and window frame down sliding sash.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Lower open-and-close mechanism 3 is arranged on 2 li of the lower frame 1 of sash and window frame down sliding sashs.On the rocking bar 34 of lower open-and-close mechanism, establish pulley 39 as the protruding strong point, pulley is positioned between the mid point (referring to the mid point between back shaft 32 and sash axle 31) and back shaft 32 of rocking bar 34, and pulley withstands on the lower frame 1 of sash.At this moment rocking bar is as lever, and back shaft is as the fulcrum of this lever, and sash axle and pulley are as two stress points.The present invention utilizes lever principle, and most of weight of sash is passed through to pulley off-load to back shaft.Adopt pulley can reduce the frictional force between fulcrum and sash lower frame.
Claims (1)
1. flat open the lower open-and-close mechanism of slide door or window, it comprises sash axle, rocking bar and back shaft, it is characterized in that: between the mid point of rocking bar and back shaft, establish the strong point of a projection, this strong point withstands on the lower frame of sash; The strong point of said projection is pulley.
