Regression buffering structure

Abstract

The invention discloses a regression buffering structure which comprises a shell body mechanism, a sliding mechanism, a stirring piece, an elastic piece and a buffering mechanism. The sliding mechanism is arranged in the shell body mechanism in a sliding mode. The stirring piece is provided with a stirring part which abuts against the sliding mechanism in a separable mode in a clamping mode. The elastic piece is arranged in the shell body mechanism. The buffering mechanism is arranged in the shell body mechanism. The buffering mechanism comprises a hollow outer pipe, a first pushing rod and a second pushing rod. One end of the first pushing rod is arranged in the hollow outer pipe in a sliding-sleeved mode from a first end. One end of the second pushing rod is arranged in the hollow outer pipe in a sliding-sleeved mode from a second end. The buffering mechanism comprises the hollow outer pipe and the two pushing rods, compared with a commonly-used oil pressure damping device of a regression buffering device, a longer buffering stroke is provided so that the time of buffering damping effect can be prolonged, and then the effects of effective buffering improving and noise lowering can be achieved.

Description

technical field [0001] The invention relates to a return buffer structure, especially a return buffer structure which can prolong the time of the buffer damping effect, thereby effectively improving the buffer and reducing noise. Background technique [0002] General return buffer device, such as Taiwan Patent Publication No. M378270 "Semi-automatic door closing buffer device", please refer to figure 1 As shown, it includes an oil pressure damping device 10, a housing 11 and a sliding buckle device 12, wherein the oil pressure damping device 10 has an oil pressure barrel 101 and a piston rod 102, and one end of the piston rod 102 is slidable It is set in the oil pressure barrel 101, the casing 11 covers the oil pressure damping device 10 and the oil pressure damping device 10 is fixed in the casing 11, a track 111 is formed on the casing 11, and the casing 11 can be For fixed installation with the door body, the sliding buckle device 12 is fixed with the other end of the pi...

Problems solved by technology

[0003] Although this conventional return buffer device can achieve the purpose of reducing the noise generated when closing the door, it only has a single oil pressure damping device 10, so the stroke that the piston rod 102 can slide in the oil pressure barrel 101 is usually relatively short, resulting in When the piston rod 102 is retracted into the oil pressure barrel 101, it may quickly collide with the inner wall of the oil pressure barrel 101, and the buffering effect and noise reduction effect of the conventional return buffer device are relatively limited. Therefore, how to aim at The above-mentioned deficiencies are improved, which is the technical difficulty that the inventor of this case wants to solve
