Regression buffer structure

This creation is about a regression buffer structure, especially a regression buffer structure that can prolong the buffer damping effect, thereby effectively improving buffering and reducing noise.

A general regression buffer device, such as the "semi-automatic door closing buffer device" of the Republic of China Patent Gazette No. M378270, which is shown in the first figure, includes a hydraulic damping device 10, a casing 11 and a sliding fastener device 12. The hydraulic damper device 10 has a hydraulic pressure tank 101 and a piston rod 102. One end of the piston rod 102 is slidably disposed in the oil pressure tank 101. The outer casing 11 covers the oil pressure damping device 10 and The oil pressure damping device 10 is fixed in the outer casing 11. The outer casing 11 is formed with a rail 111, and the outer casing 11 is fixed to the door body. The sliding buckle device 12 is opposite to the other end of the piston rod 102. The latching device 12 is provided with a latching member 121, and the latching member 122 is formed with a latching slot 122 for engaging with the latching block of the door frame; When the door body is closed, the sliding buckle device 122 of the sliding buckle device 12 is combined with the latching block of the door frame, so that the sliding buckle device 12 can be stopped. At the block of the door frame, the door can still continue to move and drive the door The shell 11 and the oil pressure tank 101 continue to move toward the door frame, so that the piston rod 102 can be retracted into the oil pressure tank 101, and a resistance can be generated to slow down the impact force when the door body contacts the door frame, thereby achieving Reduce the noise caused by noise when closing the door.

The conventional regression buffer device can achieve the purpose of reducing the noise generated when the door is closed, but only has a single hydraulic damper device 10, so that the stroke of the piston rod 102 in the oil pressure tank 101 is usually short, resulting in a short stroke. When the piston rod 102 is retracted into the hydraulic pressure tank 101, it may quickly collide with the inner raft of the hydraulic pressure tank 101, thereby causing the buffering effect and the noise reduction effect of the conventional regression buffer device to be limited. The above-mentioned deficiencies are improved, that is, the technical difficulties that the creators of this case want to solve.

In view of the existing regression buffer device, since only a single hydraulic damping device is provided, the buffer stroke is short, and the buffering effect and the noise reduction effect are relatively limited. Therefore, the purpose of the present invention is to provide a regression buffer structure by using the present invention. The buffer mechanism is composed of a hollow outer tube and two tie rods, and can provide a longer buffer stroke than the oil pressure damping device of the conventional regression buffer device, and can prolong the buffer damping effect, thereby making the creation effective. Improve buffering and reduce noise.

In order to achieve the above object, the present invention provides a regression buffer structure comprising: a housing mechanism; a sliding mechanism slidably disposed in the housing mechanism; a paddle, the paddle setting a slidable portion is detachably engaged with the sliding mechanism; an elastic member is disposed in the housing mechanism; and a buffering mechanism is disposed on the housing In the mechanism, the buffer mechanism includes a hollow outer tube, a first push rod and a second push rod, and the first push rod is slidably received by the first end in the hollow outer tube. One end of the second push rod is slidably sleeved in the hollow outer tube from the second end.

The buffer mechanism of the present invention is composed of a hollow outer tube and two tie rods, and can provide a longer cushioning stroke than the oil pressure damping device of the conventional regression buffer device, and can be extended. The time of the damping effect, which in turn enables the creation to effectively improve buffering and reduce noise.
