Abstract

The invention relates to a buffering device. The buffering device comprises a cylinder body, a covering assembly, a piston rod and an elastic piece, wherein the cylinder body comprises a cavity defined by the inner wall of the cylinder body and an opening communicating with the cavity, and the cavity is filled with a buffering fluid; the covering assembly is arranged at the opening adjacent to the cylinder body; the piston rod can move relative to the cylinder body, the piston rod comprises a rod part, an extension part and an expansion part between the rod part and the extension part, the rod part penetrates through the covering assembly, and the width of the expansion part is larger than the width of the rod part; and the elastic piece is arranged in the cavity of the cylinder body and is used for providing elasticity for 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...
