[0003] For the sliding door buffers on the market, if the sliding door needs to be closed in place when the door is closed, more force is required to open the buffer when the door is opened, which is laborious
At the same time, the inertial force when closing the door plus the tension of the extension spring will make the damping device go straight to the bottom, affecting the user experience

The invention relates to a door sliding buffer by inertial force, which includes a buffer shell, a rotating block, a damping device and a tension spring. Both the damping device and the tension spring are installed in the buffer shell, and one end of the damping device is Connected with the rotary block, the inner wall of the buffer shell is provided with an upper chute and a lower chute in parallel, the rotary block slides along the lower chute, and one end of the tension spring is connected with a puller that slides along the upper chute. A spring connector, both sides of the bottom surface of the tension spring connector are arranged with a wave groove along the length direction, a boss matching the wave groove is provided on the rotating block, and a card interface is provided at the bottom of the rotating block. There is a pressure jacking device at the card interface. The greater the inertial force of the sliding door when the door is closed, the shorter the working distance of the extension spring, and the smaller the work required to reset the extension spring when the door is opened, thereby achieving the purpose of labor saving.
Description
technical field [0001] The invention relates to the technical field of sliding door buffering, in particular to a door sliding buffer by means of inertial force. Background technique [0002] Sliding door is a common door that can be pushed and pulled left and right, especially for some occasions where the space is relatively narrow, people usually use sliding door. The sliding door buffer is often used on the sliding door to buffer the sliding door to avoid collision between the sliding door and the door frame. [0003] For the sliding door buffers on the market, if the sliding door needs to be closed in place when the door is closed, more force is required to open the buffer when the door is opened, which is laborious. At the same time, the inertial force when closing the door plus the tension of the extension spring will make the damping device go straight to the bottom, affecting the use experience. Contents of the invention [0004] The technical problem to be solve...
