In a first aspect, a buffer according to some embodiments of the present invention, as shown in fig. 1 and 4, includes: a frame 100, a moveable member 200, and a resilient member 300. The movable piece 200 is movably arranged on the frame 100; the elastic member 300 is connected to the frame 100 at one end and to the movable member 200 at the other end. The elastic member 300 is connected to the frame 100 and the movable member 200, and the elastic member 300 springs the movable member 200 away from the frame 100.

When the external force applied to the movable element 200 is greater than the elastic force of the elastic element 300, the movable element 200 moves toward the frame 100, and when the external force applied to the movable element 200 is less than the elastic force of the elastic element 300, the movable element 200 moves away from the frame 100. In the installation process of the buffer, when a gap exists between the buffer and the door rail, the external force applied to the movable member 200 is smaller than the elastic force of the elastic member 300, and the movable member 200 moves to the direction away from the rack 100 to contact with the door rail, thereby realizing the function of automatically adjusting the height of the buffer relative to the door rail. The movable piece 200 can be moved towards the direction close to the machine frame 100 by pressing the movable piece 200 to compress the buffer, so that the volume of the buffer is reduced, and the buffer can be installed in spaces with different sizes in the installation process. When the movable member 200 contacts the door rail, the elastic force of the elastic member 300 acts on the movable member 200 to press the movable member 200 against the door rail, thereby ensuring the stability of the contact between the movable member 200 and the door rail.

According to some embodiments of the present invention, as shown in fig. 2, the elastic member 300 includes a connection member 310 and an elastic member 320, wherein the connection member 310 is hinged to the frame 100 at one end and to the movable member 200 at the other end, and the elastic member 320 is connected to the frame 100 at one end and to the connection member 310 at the other end. The elastic member 320 acts on the connecting member 310, the connecting member 310 is hinged to the movable member 200, the connecting member 310 can drive the movable member 200 to move, and the elastic member 320 indirectly acts on the connecting member 310.

It will be readily understood by those skilled in the art that the elastic member 320 may also be connected to the frame 100 at one end and the movable member 200 at the other end, and the elastic member 320 directly applies elastic force to the movable member 200. The elastic member 320 may be an elastic member such as a spring, a torsion spring, or the like.

According to some embodiments of the present invention, the damper further includes an adjustment assembly 400, the adjustment assembly 400 is disposed on the frame 100, and the adjustment assembly 400 is used to adjust the maximum distance of the movable member 200 from the frame 100.

Under the condition that the buffer is not affected by external force, the movable element 200 is away from the machine frame 100 under the action of the elastic element 320, the movable element 200 is located at the limit position where the movable element 200 can be away from the machine frame 100, at the moment, the size of the buffer is large, in the actual installation process, the installation space of the buffer is relatively small, the size between the movable element 200 and the machine frame 100 is overlarge, and in order to install the buffer, the movable element 200 needs to generate large displacement, which is not beneficial to installation. To address this problem, some embodiments of the present invention provide an adjustment assembly 400, the adjustment assembly 400 being used to adjust the maximum distance of the moveable member 200 from the frame 100. The limit distance between the adjusted movable member 200 and the frame 100 is reduced, the size of the buffer is reduced, and the displacement of the movable member 200 required to be generated in the actual installation process is reduced, so that the movable member is convenient to install in a smaller space. In actual installation, the limit distance between the movable member 200 and the frame 100 may be adjusted according to the installation space.
