Abstract

The invention relates to a buffer device, which includes a cylinder body, a cover assembly, a piston rod and an elastic member. The cylinder includes an inner wall defining a chamber and an opening communicating with the chamber, the chamber is filled with a buffer fluid; the covering component is disposed adjacent to the opening of the cylinder; the piston rod is movable relative to the cylinder, The piston rod includes a rod portion, an extension portion, and an expansion portion located between the rod portion and the extension portion, the rod portion passes through the cover assembly, and the width of the expansion portion is greater than the width of the rod portion; the elastic A component is disposed in the chamber of the cylinder, and the elastic component is used to provide elastic force to the piston rod.

Description

technical field [0001] The invention relates to a buffer device, in particular to a buffer device applied to furniture objects. Background technique [0002] Generally speaking, some specific furniture, such as doors or cabinets, will be equipped with cushioning devices. The buffer device can be used to provide a buffering function when the first member is relative to the second member from opening to closing, so as to slow down the force when the first member is closing relative to the second member. For example, US Patent No. US9,021,656B2 discloses a cushioning device for furniture comprising a slide seat (13), a piston (22) and a piston rod (17). Among them, by the case Figure 4 It can be seen from a, 4b that one end of the piston rod (17) is connected to the piston (22), and the piston (22) is located in a chamber (21) of the slide seat (13). [0003] Specifically, according to the related technology of the current buffer device, the piston rod is generally a slender...
