Simple and easy friction-type descending lifeline
Technical field
The utility model relates to a kind of escape device.
Background technology
Because many factors, tragedies such as fire happen occasionally, and bring on a disaster and lose to the country and people, and we must enhance your vigilance, and prevent trouble before it happens.For unexpected dangerous situation, particularly be in the people of eminence, no matter be at high building or steamer, how smoothly life is protected at the escape unharmed scene, is vital.On the current market, many escape devices are arranged, what wherein have is heavier or huge, be unfavorable for carrying and installing,, be sought after a walk away safety for building resident or steamer personnel, and convenient practical escape device, based on this demand, we have designed a simple and easy friction-type descending lifeline.
The utility model content
The utility model purpose provides a kind of simple in structure, simple and easy friction-type descending lifeline that cost is low.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of simple and easy friction-type descending lifeline comprises lacing hole, framework, mill sassafras post, it is characterized in that: described mill sassafras post is connected with frame fixation, and framework is provided with two lacing holes, and the lower end of framework is provided with fixedly manhole.
Described mill sassafras post is two.
Described lacing hole is provided with the abrasionproof packing ring.
The beneficial effects of the utility model are: this simple and easy friction-type descending lifeline is simple in structure, and cost is low, can control the speed that the people descends, and successfully arrives safely, can certainly control top personnel by pulling cord by following personnel and descend; Can be widely used in emergency escapes such as high building, steamer, can be used for also that personal security on the helicopter descends and aspect such as rescue and relief work; Can come by following people decrease speed is regulated.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 schematic diagram of the present utility model;
Fig. 2 front view of the present utility model;
Fig. 3 side view of the present utility model.
The specific embodiment
As Figure 1-3, a kind of simple and easy friction-type descending lifeline comprises lacing hole 1, framework 2, mill sassafras post 5, and described mill sassafras post 5 is fixedlyed connected with framework 2, and framework 2 is provided with two lacing holes 1, and the lower end of framework 2 is provided with fixedly manhole 3; Mill sassafras post 5 is two; Lacing hole 1 is provided with abrasionproof packing ring 4.The people can control the size of pulling force T, the speed that control descends; Can regulate the speed of decline very easily to the size of the rope application of force according to the people; can effectively avoid like this owing to quicken to cause the too fast accident that causes of decrease speed for a long time; equally also reduce in the decline process because fricative heat the better protection rope.
Friction is one of shortcoming of this device to the damage that rope produces, so the life-span that the friction between rope and device can reduce rope puts abrasionproof packing ring 4 in contact position up and down, abrasionproof packing ring 4 can be for materials plastics or other damages of reducing friction, to increase the service life of rope.
A lot of people in accident, can occur and need withdraw on-the-spot situation, can be designed to two symmetry, after a personal security lands, only need rope is dragged back upstairs, the other end be put down just can significantly reduce withdraw the on-the-spot time.
During use, at first hook is fixed on suitable positions such as iron, and fasten seat belts, hand catches the rope of descending lifeline below to glide along rope then, because there are the effect of flexible friction in rope and axle, the speed of decline is slowed down, as long as the control hand pulls down the pulling force of rope, just can control the speed of decline, successfully arrive safely.
