Further, with respect to the thickness direction of the slider 2, one end of the slider 2 is provided with a second sliding surface 5 that cooperates with the first sliding surface 4, and the other end is a friction surface 6, and the friction surface 6 is used for forming friction with an external member (such as a window frame), and the slider 2 and the base 1 form sliding contact with the first sliding surface 4 through the second sliding surface 5, that is, the first sliding surface 4 and the second sliding surface 5 are movable contact surfaces of the protruding portion 3 and the slider 2. Further, when the slider 2 moves toward the first end of the first sliding surface 4, that is, when the slider 2 moves along the boss 3 and toward the high position of the inclined surface thereof, the slider 2 is lifted or raised with respect to the base 1.

Specifically, the boss 3 and the slide block 2 are arranged on the base 1, and the first sliding surface 4 and the second sliding surface 5 which are mutually matched are respectively arranged on the boss 3 and the slide block 2, wherein one end of the first sliding surface 4 is higher and the other end is lower (inclined surface or sloping surface); when the buffer is mounted on the window and the sliding direction of the window sash is towards the lowest point of the first sliding surface 4, at this time, as the window sash slides, the friction surface 6 on the sliding block 2 moves reversely along with the friction force of the sliding block with the window frame, so that the sliding block 2 is forced to move towards the high point (the high point of the inclined plane) of the first sliding surface 4, namely, the sliding block 2 is lifted by a distance relative to the base 1 relative to the thickness direction of the base 1, and the friction force of the window sash relative to the window frame is further increased; further, for example, in a window sash sliding up and down, the friction force between the friction surface 6 of the sliding block 2 and the window frame of the window sash which is opened up enables the window sash to be in a hovering state and not to fall freely, when the window sash needs to be closed, a certain force is applied to the window sash by a user so as to overcome the friction force of the window sash relative to the window frame, or the window sash is buffered in the closing process; similarly, when the user operates the window sash to move in the opposite direction (open the window sash), that is, the sliding direction of the window sash faces to the highest point (the high point of the inclined plane) of the first sliding surface 4, under the action of the friction force between the friction surface 6 of the sliding block 2 and the window frame, the sliding block 2 moves to the low point of the self-protruding part 3, so that the friction surface 6 of the sliding block 2 moves to the base 1, thereby effectively reducing the friction force between the sliding block 2 and the window frame, that is, the window sash can be easily opened; that is, the relative movement of the sliding block 2 relative to the protruding portion 3 can realize the adjustment of the friction force when the window sash is opened and closed relative to the window frame, so that the composition structure of the buffer is effectively simplified, the guide rail strips can be omitted compared with the prior art, and the convenience of the buffer in the installation process is improved.

Further, when the friction surface 6 of the slider 2 is in direct contact with an external member (window frame) and moves relatively, the friction formed between the slider 2 and the window frame is sliding friction, that is, relatively great abrasion is caused to the slider 2 and the window frame during long-term use; when the roller 7 is used, the friction formed between the sliding block 2 and the window frame is converted into rolling friction, so that the abrasion generated by the sliding block 2 when moving relative to the window frame is effectively reduced. Further, with respect to the movement resistance of the window sash with respect to the window frame, the resistance generated by the sliding friction is converted into the resistance generated by the rolling friction when the roller rolls. Further, for the length direction of the sliding block 2, the second sliding surface 5 is located between the two rollers 7, and the second sliding surface 5 is arranged between the two rollers 7, so that the phenomenon that the sliding block 2 is warped when being stressed can be avoided.
