Abstract
The utility model discloses a kind of anti-falling overhead buffer units, including transparent cavity, fixed rope and air inlet are provided at the top of transparent cavity, transparent cavity bottom is provided with venthole, transparent inside cavity is provided with diameter sliding ball identical with housing width, sliding ball bottom is connected with fall prevention rope, fall prevention rope passes through the venthole, when human body falls, the fall prevention rope being fixed on human body pulls sliding ball to glide, due to the air inlet bore dia very little at the top of transparent cavity, in sliding ball dropping process, it is seldom that the intracorporal air of transparent chamber is entered by air inlet, to which the intracorporal pressure of transparent chamber on sliding ball top is lower, and the intracorporal pressure of transparent chamber of sliding ball lower part is much larger than the pressure on top, effectively sliding ball can be prevented to hurtle down, it avoids as hurtling down to damage caused by human body, with good Antisitic defect buffering effect.
Description
Technical field
The utility model relates to high-altitude safe protection and emergency management and rescue field more particularly to a kind of anti-falling overhead buffering dresses
It sets.
Background technique
Currently, being required to use of seat belts, safety rope, delaying when carrying out high altitude operation and certain outdoor extreme sports
The devices such as punching band and measure ensure that personnel fall, and ensure personal safety, buffer is a kind of acceptor of energy, is preventing eminence from making
Industry personnel in fall injury by playing an important role, and fall prevention rope is only bent and rolls over by fall arrest buffer used at present
It is stacked in plastic button bag, human body once falls, and the fixing buckle in plastic button bag is beaten one by one under the pulling force effect of human body fall
It opens, prevents human body fall, this traditional buffer buffering effect is undesirable, although being avoided that personnel fall to fall falls death,
But it often will cause the damage of human body, it is therefore desirable to propose a kind of high altitude anti-falling buffer unit, there is good buffering effect, energy
Effectively avoid the damage of human body in drop event.
Summary of the invention
The technical problem solved by the utility model is:to provide a kind of anti-falling overhead buffer units, to solve traditional delay
The problem of rushing that device buffering effect is undesirable, the damage of human body be easy to cause in personnel's drop event.
The technical solution of the utility model includes:
A kind of anti-falling overhead buffer unit, including transparent cavity, be provided at the top of the transparent cavity fixed rope and
Air inlet, the transparent cavity bottom are provided with the venthole of adjustable section, and the transparent inside cavity is provided with directly
Diameter sliding ball identical with housing width, the sliding ball bottom are connected with fall prevention rope, and the fall prevention rope passes through described
Venthole.
The air inlet bore dia is 0.5-1cm.
The outlet bore dia is bigger than air inlet bore dia.
The fixed rope and fall prevention rope is insulating cord.
The transparent cavity is made of insulating materials.
The utility model has the beneficial effects that a kind of anti-falling overhead buffer unit is provided, by being arranged in transparent chamber body
There is diameter sliding ball identical with housing width, sliding ball bottom is connected with fall prevention rope, when human body falls, is fixed on people
Fall prevention rope on body pulls sliding ball to glide, due to the air inlet bore dia very little at the top of transparent cavity, in sliding ball dropping process
In, it is seldom that the intracorporal air of transparent chamber is entered by air inlet, so that the intracorporal pressure of the transparent chamber on sliding ball top is lower,
And the intracorporal pressure of transparent chamber of sliding ball lower part is much larger than the pressure on top, can effectively prevent sliding ball from hurtling down, keep away
Exempt from that there is good antisitic defect buffering effect as hurtling down to damage caused by human body.
Detailed description of the invention
Fig. 1 is the utility model surface structure schematic diagram；
It is identified in figure: 1, transparent cavity, 2, fixed rope, 3, sliding ball, 4, fall prevention rope, 5, air inlet, 6, venthole.
Specific embodiment
The utility model is described further with reference to the accompanying drawing, a kind of anti-falling overhead described in the utility model is slow
Flushing device, including transparent cavity 1 made of pvc material are provided with fixed rope 2 at the top of the transparent cavity 1 and diameter are
The air inlet 5 of 0.5-1cm, adjustable section, 2 top of fixed rope are provided with hook, hang in height in fixed structure, institute
1 bottom of transparent cavity stated is provided with venthole 6, and it is identical with housing width that the transparent cavity 1 is internally provided with diameter
Sliding ball 3,3 bottom of sliding ball are connected with fall prevention rope 4, and the fall prevention rope 4 passes through the venthole 6 and human body and connects
It connects.
6 diameter of venthole is bigger than 5 bore dia of air inlet, can be effectively ensured in the transparent cavity 1 on 3 top of sliding ball
Air than few in the transparent cavity 1 of 3 lower part of sliding ball, thus under being lower than the pressure of the transparent cavity 1 on 3 top of sliding ball
The pressure in portion.
The fixed rope 2 and fall prevention rope 4 is insulating cord, such as polyester fiber, polyester fiber, spandex fibre or nylon
Insulating cord made of the materials such as fibre.
In field of power system in application, can effectively prevent electric shock, ensure personal safety.
When human body falls, the fall prevention rope 4 being fixed on human body pulls sliding ball 3 to glide, since transparent cavity 1 pushes up
The 5 diameter very little of air inlet in portion enters the air in transparent cavity 1 very by air inlet 5 in 3 dropping process of sliding ball
Few, so that the pressure in the transparent cavity 1 on 3 top of sliding ball is lower, and the pressure in the transparent cavity 1 of 3 lower part of sliding ball is remote
It greater than the pressure on top, can effectively prevent sliding ball 3 from hurtling down, and slowly fall, avoid due to hurtling down to people
It is damaged caused by body, there is good antisitic defect buffering effect.
