Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so as to more clearly understand the technical idea claimed in the present invention.

As shown in fig. 1-3 the utility model relates to a take buffering fire prevention window closer for normally open flat-open fire window, including window closer body 1, cylinder body 2, first rocking arm 3, second rocking arm 4 and elastic component 5, window closer body 1 installs on the windowsill, cylinder body 2 installs on the lower rail of window, 3 one end of first rocking arm with window closer body 1 connects, window closer body 1 drive thereby 3 motions of first rocking arm drive window are opened closedly, first rocking arm 3 with 4 sliding connection of second rocking arm, 5 one end of elastic component is hugged closely first rocking arm 3, the 5 other ends of elastic component are hugged closely second rocking arm 4, second rocking arm 4 with cylinder body 2 is articulated.

It should be noted that window closer body 1 is the slider formula normally that uses always and normally opens fire prevention window closer, it includes mount pad, slide rail, slider, locking lever, locating piece, torsional spring, temperature sensing glass ball etc. belongs to known technology commonly used, first rocking arm 3 is installed on the slider of window closer body 1, first rocking arm 3 rotates with the slider to be connected.

When the window needs to be closed quickly, the window closer body 1 pulls the first rocker arm 3, so that the elastic part 5 is pulled, the second rocker arm 4 is pulled, the window is pulled to be closed, the second rocker arm 4 receives the pulling force from the elastic part 5, the elastic part 5 receives the pulling force of the first rocker arm 3, part of the pulling force is converted into the acting force required by the elastic variable of the elastic part 5, and therefore the window completes the closing action under the condition of less pulling force, and the buffering effect on the window is realized; the window closer body 1 pulls the first rocker arm 3 to move backwards continuously, so that the elastic part 5 is always in a stretching state, the elastic part 5 always generates a pulling force on the second rocker arm 4, the pulling force is always applied after the window closer body is closed, and the window is closed tightly.

The utility model has the advantages that: 1. the first rocker arm 3, the second rocker arm 4 and the elastic piece 5 are arranged, so that the tensile force applied to the window is partially converted into the deformation force of the elastic piece 5, and the buffer effect on the window is realized; 2. through the elastic piece 5, the pulling force given to the second rocker arm 4 by the elastic piece 5 is always received after the window is closed, so that the window is tightly closed.

Further, the swing arm device further comprises a limiting plate 6, and the first swing arm 3 and the second swing arm 4 are respectively and fixedly provided with the limiting plate 6 used for limiting the relative sliding range of the first swing arm 3 and the second swing arm 4.

More specifically, by providing the limiting plates 6, the relative sliding distance between the first rocker arm 3 and the second rocker arm 4 is between the two limiting plates 6, so that the first rocker arm 3 and the second rocker arm 4 are prevented from being disengaged due to excessive sliding of the first rocker arm 3 and the second rocker arm 4.

Further, a guide groove 31 is formed in the first rocker arm 3, a sliding groove 41 is formed in the second rocker arm 4, the outer wall of the sliding groove is matched with the inner wall of the guide groove 31, and the guide groove 31 is matched with the sliding groove 41 to enable the first rocker arm 3 to be connected with the second rocker arm 4 in a sliding mode.

More specifically, by providing the guide groove 31 and the slide groove 41, the sliding direction accuracy of the first rocker arm 3 and the second rocker arm 4 is ensured.

Further, the elastic member 5 includes an end plate 51, a spring 52 and a screw 53, the end plate 51 is fixedly arranged at both ends of the spring 52, the end plate 51 is provided with a tooth hole, and the two end plates 51 are respectively fixedly arranged on the first rocker arm 3 and the second rocker arm 4 through the screw 53.
