Embodiment

[0015] The structural diagram of the piston type slow-down mechanism is attached figure 1 As shown, there is a threaded hole at the bottom of the piston cylinder 1, and the threaded plug 3 is screwed into the threaded hole, and the threaded plug 3 is opened like figure 2 As shown in the vent hole, when the turntable 5 rotates, the eccentric shaft on it drives the connecting rod 4 to move together, and the connecting rod 4 drives the piston to reciprocate together in the piston cylinder. At this time, if the screw plug adjusts the opening amount of the vent hole , so that the piston reciprocates under a certain damping, and then realizes the function of decelerating the turntable, thereby realizing the function of slowing down. figure 1 The model shown is a turntable driving two pistons, which increases the safety of the mechanism, makes the damping effect more uniform, and the slow-down effect is more obvious. image 3 Shown is a cross-sectional view of the mechanism, in whi...

Abstract

The invention relates to a piston type damping mechanism which can be widely used for devices or equipment with speed reduction requirement in the fields such as high-rise safe fall, fire control, working at heights, outdoor mountaineering and military airborne landing. When the piston in the mechanism performs reciprocating motion, as small holes are arranged at the bottom of a piston cylinder, air can generate a certain resistance in the exhausting and pumping process, so as to realize the function of resistive movement. The mechanism has the advantages of small volume, light weight and high reliability. A plurality of the mechanisms can be used at the same time, so that the safety and the safe fall effect can be better improved. The mechanism can be used for various descent control devices and personnel protectors for maintaining and landing and has wide application prospect.

Description

technical field [0001] The invention relates to a piston-type damping mechanism, which can be widely used in equipment or devices that need to be decelerated, such as rescue and escape of high-rise buildings, high-altitude operations, outdoor mountain climbing and other fields. Background technique [0002] With the acceleration of urban construction, the urban land is becoming increasingly tense, forcing human beings to develop to high altitudes, and there are more and more high-rise buildings. However, as the proportion of people living in high-rise buildings increases, once unpredictable emergencies such as fires and earthquakes occur And so on, the traditional rescue device for firefighters cannot make high-rise residences, people in office buildings evacuate quickly and safely. At the same time, people's outdoor sports are gradually increasing, and the demand for some smart and effective high-altitude protective equipment is also stronger. In this context, the damping ...
