Description
Technical field
The invention belongs to extinguisher, more specifically to a kind of descending lifeline.
Background technology
Locate high building personnel, it is inevitable to be down to ground from delaying outside window with both hands and biped along rope-lowering when fire occurs
Or safe level and seek survival, this process, both hands epidermis can not continue slow drop often because by rope wear or heat, therefore, carry
For a kind of descending lifeline, have a very important significance.
Invention content
The object of the present invention is to provide a kind of descending lifelines.
A kind of descending lifeline of the present invention, including rope, upward and downward be mutually spirally connected on comfort hand and under comfort hand, the rope upper end
Be provided with band gate stop, the rope lower end there are one the knot with dog hole, it is described on comfort hand and under comfort and hand-tight close be set on the rope
Sub outer, end on hand is comforted under described a turriform external screw thread containing several upward and downward jags, it is described on comfort subordinate end and then have internal thread, institute
State comfort hand and it is described under comfort be equipped between hand it is anti-divide decylization, hand is comforted under described and also borrows that belt is downward the branch for being coated at the rope
Toe ring, the branch toe ring internal diameter be more than the band gate stop and it is described on comfort hand and it is described under comfort the outer diameter of hand.
The present invention has the advantages that compared with prior art：
Ask survivor's both hands hold respectively comforted on described hand and it is described under comfort hand, biped steps on the branch toe ring, along the rope
During downslide, can borrow rotate comforted on described hand and it is described under comfort hand, with adjust it is described under to comfort being spirally connected for hand and the rope tight
Looseness controls gliding speed, bites the rope to comforting hand under described as adjusted, then on-slip, tense-lax, guarantee are asked in multiple times in this way
Survivor's both hands epidermis smoothly delays without abrasively and is down to ground or safe level.And can contact use between several descending lifelines.
Description of the drawings
Fig. 1 is the structure diagram of descending lifeline of the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1, a kind of descending lifeline of the present invention, including rope 1, upward and downward be mutually spirally connected on comfort hand 2 and under comfort hand 3,
1 upper end of rope is provided with band gate stop 4,1 lower end of rope there are one the knot 5 with dog hole, it is described on comfort hand 2 and under comfort hand
3 are closely set on outside the rope 1, and 3 upper end of hand is comforted under described a turriform external screw thread containing several upward and downward jags, it is described on comfort
Then there is an internal thread in 2 lower end of hand, it is described on comfort hand 2 and it is described under comfort be equipped between hand 3 it is anti-divide decylization 6, hand 3 is comforted under described and also borrows belt
7 it is downward have a branch toe ring 8 for being coated at the rope 1,8 internal diameter of branch toe ring be more than the band gate stop 4 and it is described on comfort hand 2
And it is described under comfort the outer diameter of hand 3.
The branch toe ring 8 with it is described under comfort 3 spacing of hand and be advisable with 1.2-1.6 meters, asked using adapting to height as 1.0-1.8 meters
Survivor.Comforted on described hand 2 and it is described under comfort hand 3 preferably with the high plastic production of engineering strength.Descending lifeline of the present invention locates spare state
When, hand 3 is comforted under described and is fastened with the rope 1, after asking survivor in place, as long as both hands, which are slightly unscrewed, comforts hand 2 on described
And it is described under comfort thread mechanism between hand 3, then can borrow its own gravity along the slow drop of the rope 1.Several descending lifelines series winding in use,
The next its described 5 hook of the knot with gate stop 4 Yu upper a descending lifeline of a descending lifeline, the stempoda of upper a descending lifeline
Ring 8 be down to the next descending lifeline it is described under when comforting under hand 3, both hands are transferred to the next descending lifeline from upper a descending lifeline.
