Description
Technical Field
The utility model relates to the technical field of doors and windows, in particular to a door and window underslung connecting device.
Background
Currently, in order to achieve the effect of safe ventilation, a window sash of a household door or window generally has the functions of inward opening and downward suspension, and the window sash of the door or window needs to achieve the downward suspension function, so that a downward suspension hardware is required to be installed between the upper part of the window sash and a window frame. As shown in fig. 1 and 2, a transmission rod capable of controlling movement by a handle is arranged at the outer edge of the window sash, and drives the diagonal draw bar of the lower suspension hardware to work so as to drive the upper part of the window sash to move inwards, thereby realizing the lower suspension of the window sash.
The existing inward-opening down-hung window can be opened inwards by pulling the handle inwards after the handle is rotated upwards to be in a vertical state, but can be opened by two independent steps, so that vibration and noise of the window sash are increased in the process of opening and closing the window sash, and the sealing strip between the window sash and the window frame deforms due to frequent collision after long-time use, so that shaking can occur between the window sash and the window frame when the window frame is closed, and the tightness of the window sash is affected.
Disclosure of utility model
In order to solve the technical problems in the background technology, the utility model provides a door and window underslung connecting device.
The technical scheme of the utility model is as follows:
The door and window underslung connecting device is arranged on a door and window, the door and window comprises a window frame and a window sash, the window sash can be opened and underslung in the window frame through a handle and a right-angle transmission mechanism, the right-angle transmission mechanism comprises a corner device positioned at the corner of the window sash, the corner device is provided with an elastic pull piece in transmission connection with the handle, the elastic pull piece is connected with a underslung connecting piece, the underslung connecting piece comprises a first connecting rod and a second connecting rod which are sequentially hinged, one end of the first connecting rod is close to the corner of the window sash and is hinged with the upper edge of the window sash, the other end of the first connecting rod is hinged with the middle part of the second connecting rod, one end of the second connecting rod is hinged with the window frame through a roller, the other end of the second connecting rod is movably connected with the upper edge of the window sash through a connecting piece, and one end of the first connecting rod and the connecting piece are arranged along the length direction of the window frame;
The first connecting rod is located the second connecting rod below, has offered on the first connecting rod and has rolled over shape guide way, is equipped with the slider of sliding connection in rolling over shape guide way on the elasticity pulling-on piece, and the second connecting rod below can be dismantled and be connected with the latch segment, and the lower terminal surface of latch segment is located first connecting rod up end top, and the latch segment can be in the casement for closed state top tight to slider one side.
When the handle is rotated upwards by the level, the slider slides in the guide way of book shape, and the contained angle of second connecting rod and head rod grow, and the head rod drives the upper portion of casement and inwards moves, and the casement changes into down to hang by the inwardly opened, and the angle of casement upper portion inwards slope becomes big along with the contained angle grow of second connecting rod and head rod, need not the manual upper portion of casement inwards to pull just can realize down hanging, reduces the problem of collision, wearing and tearing between casement and the window frame that the maloperation produced.
The concrete structure of the folded guide groove is that the folded guide groove comprises a first guide groove and a second guide groove which are communicated, the first guide groove is arranged along the length direction of the first connecting rod and is inclined, the inclined direction is inclined towards the outer side face of the window sash, when the sliding block moves from the locking end to the other end in the first guide groove, the sliding block can drive the upper portion of the window frame to be opened in an inward inclined manner, one end of the first guide groove, which is far away from the second guide groove, is the locking end, one end, which is far away from the locking end, of the second guide groove extends along the opening direction of the window sash, the opening direction of the second guide groove is matched with the opening direction of the window sash, and when the sliding block moves to the second guide groove, the upper portion of the window sash can be gradually opened in an inward inclined manner to be in a downward suspension.
In order to realize that the sliding block moves to the second guide slot from the first guide slot, the upper part of the window sash can be simultaneously inclined and opened to be downwards suspended, the included angle between the first guide slot and the second guide slot is arranged between 90 degrees and 180 degrees, the included angle between the first guide slot and the second guide slot is larger, the stroke of the sliding block is longer, the stroke of downwards suspended window sash is longer, otherwise, the included angle between the first guide slot and the second guide slot is smaller, the stroke of the sliding block is shorter, the same angle is downwards suspended and opened, the stroke is shorter, and the opening speed is faster.
The setting position of the locking block is that the length direction of the locking block is consistent with the length direction of the second connecting rod, one side far away from the outer side face of the window sash is an inclined surface, and the inclined surface can move to the locking end at the sliding block and is in interference with the locking end.
