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

A kind of piston type damping mechanism

Technical field

The present invention relates to a kind of piston type damping mechanism, this mechanism can be widely used in equipment or the device that needs deceleration, such as fields such as tall building lifesaving escape, high-lift operation, outdoor mountain-climbings.

Background technique

Quickening along with the urban construction paces, urban land day is becoming tight, force the mankind to be developed to the high-altitude, high-rise building is more and more, but along with people's high-rise ratio of living is increasing, in case uncertain urgency occurs such as fire, earthquake and so on, traditional fire personnel's safety apparatus can't make high residential building, and the people of office building are withdrawing of safety rapidly.Simultaneously now people's outdoor exercises increase gradually, and the demand of high-altitude protective equipment is also stronger effectively to some dexterities.Under this background, release this kind and use the damping mechanism of piston principle, wish to promote to design and produce some delicate structure, safe and reliable life-escaping slow-landing or outdoor safety installation.

Summary of the invention

The present invention seeks to propose a kind of equipment or device that the piston damping principle can be widely used in needs deceleration that utilize, such as the protection safeguarding mechanism in the fields such as life-saving slow descending and outdoor exercises, it is rational in infrastructure, and is sturdy and durable, reliable and secure, easy to maintenance.But utilize the slow equipment that falls of this mechanism's deft design.

It is reciprocating in porose piston cylinder in the bottom that the deceleration principle of this mechanism is piston, rotate screwed plug in the movement process, make air outlet hole big or small adjustable of piston, thereby the damping size of regulating piston in cylinder, when adjusting to the appropriate location, piston will be done the to-and-fro motion of certain damping in cylinder, human body descends and can pass through the rotations such as rope belt moving gear or rotating shaft when high-lift operation, then rotation is delivered on the rotating disk, rotation is converted to the to-and-fro motion of piston by the eccentric shaft on the rotating disk, thereby realize having the adjustable slow function of falling of resistance, under specific circumstances with the whole precessions of screwed plug, with the whole shutoff of air outlet hole, can realize the braking of this mechanism, namely can realize by the method the braking of decline process.This mechanism has also designed and has been used for reducing because the piston/cylinder that connecting rod swing causes is subjected to radial force simultaneously, causes the cylinder body swing mechanism of cylinder body and piston wear.Be that this mechanism is operated in the optimum state, life-saving reduces wearing and tearing.

The advantage of life-saving slow descending of the present invention mechanism is:

1, rational in infrastructure, simple to operate, stable, safe and reliable.

2, be not subjected to the external environment variable effect, sturdy and durable, be easy to safeguard, can be repeatedly used.

3, energy saving mustn't ABAP Adapter.

Description of drawings

Embodiment

The below is described further structure and the mode of execution of piston type slow descending mechanism of the present invention with reference to the accompanying drawings in conjunction with specific embodiments.

Embodiment

The structural drawing of piston type slow descending mechanism as shown in Figure 1, one tapped hole is arranged at piston cylinder 1 bottom, screwed plug 3 precession tapped holes, screwed plug 3 has vent as shown in Figure 2, when rotating disk 5 rotates, eccentric shaft drivening rod 4 on it moves together, 4 on connecting rod drives together together to-and-fro motion in piston cylinder of piston, if the opening amount that this moment, screwed plug was regulated vent moves reciprocatingly piston under certain damping, then realize the function to the deceleration of rotating disk, thereby realized slow function of falling.Figure 1 shows that the pattern of two pistons of a driven by rotary disc, increased like this Security of mechanism, make its damping function more even, the slow effect of falling is more obvious.Figure 3 shows that the sectional view of this mechanism, cylinder body can swing at base support 7 by cover sleeve 6 thereon and the bearing pin 8 that welds thereon among this figure, piston is owing to be subjected to the pulling of connecting rod, understand the axial force that produces our needs and unwanted meeting causes wearing and tearing to cylinder body radial force, by this mechanism, when connecting rod produces radial component to piston, to drive cylinder body swings together, thereby offset radial component, make piston and cylinder body only deposit in the axial direction component, guaranteed piston at the Shi Buhui that moves reciprocatingly because unbalance stress produces wearing and tearing to cylinder body.Principle can be designed to this device the descent control installation of exquisite a plurality of piston cylinders according to this.

Drawn by above-mentioned discussion, the life saving device in the present embodiment is rational in infrastructure, and is simple, simple to operation, do not need ABAP Adapter, energy saving, and environmental protection, maintenance maintenance is convenient, can be applicable to various environment, is fit to extensively promote.

Above-described embodiment is illustrating of design proposal of the present invention, and protection domain is as the criterion with claim.

Claims

1. piston type damping mechanism that can be used for high-altitude safety flow-landing, the principle of this mechanism's Main Basis piston has the piston cylinder of tapped hole by the bottom, opens foraminate screwed plug, piston, connecting rod, with the rotating disk of eccentric shaft, base, bearing pin and sleeve form; Wherein piston cylinder and piston material are stainless steel, and piston installs O type circle seal ring and two way sealed rubber seal additional, thereby have guaranteed that sealing is good; But be with UNICOM in foraminate screwed plug precession cylinder end aperture and the cylinder, by the Throughput that how much comes regulating piston of screwed plug precession, the size of the resistance that produces during to-and-fro motion changes thereupon; After regulating, screwed plug is fixed, then this mechanism can be by the wirerope-winding of rotating disk and decline, when wire rope drives dial rotation, thereby driving one or more pistons by one or more connecting rods again, the eccentric shaft on the rotating disk in piston cylinder, does resistant to-and-fro motion realization deceleration.
