Abstract
The utility model discloses a kind of fire-extinguishing and lifesaving and fly pawl, including mobile jib, buckle and claw hook, described in buckle the one end being arranged at mobile jib, it is used for connecting rope；Described claw hook is installed on the other end of mobile jib, and for hook fixture when claw hook is in deployed condition, claw hook is in convergence state for reclaiming；It is characterized in that: be provided with back-moving spring and locking device in the junction of described mobile jib and claw hook, described back-moving spring for being maintained at convergence state by claw hook, and described locking device is for being maintained at deployed condition by claw hook.This utility model can be used for upwards climbing during fire-fighting is speedily carried out rescue work, and overcome tradition and fly pawl and reclaim not convenient problem.
Description
Technical field
This utility model relates to fire-fighting equipment field, specifically, being related specifically to a kind of fire-extinguishing and lifesaving and flying pawl.
Background technology
Fire-fighting and rescue rope end with fireman at present, general employing carbine or D type are buckled, and need and can hook during use
Hang fixing object, or can by cable loop around rear carbine or D type buckle from hang fixing object can use.Needs to
During upper climbing, then cannot directly use.
Fly pawl to be also flying tiger pawl, climb pawl, be widely used in during outdoor mountain-climbing wilderness movable, outdoor seeks survival, fixture is wanted
Ask the highest.Fly pawl and have three-jaw, four paws, structure typically has fixed claw hook and collapsible claw hook.Collapsible claw hook mainly side
Just receiving portable, launch claw hook and lock during use, usage is consistent with fixed claw hook.Both flies pawl present in the fire-fighting
Problem is, hangs after fixture declines according to flying claw hook, will regain and fly pawl and decline further, is now in and opens shape owing to flying pawl
State, easy hooking fixture or other object, it is relatively difficult to take off, needs to shake rope through the skilful strength of specialized training, allow and fly
Pawl soars and flies up and avoiding obstacles is taken off and is continuing with, otherwise can only be with the most just taking off, and this is for fire-fighting emergent
It is unfavorable to rescue.
Utility model content
The purpose of this utility model is for deficiency of the prior art, it is provided that a kind of fire-extinguishing and lifesaving flies pawl, to solve
The problems referred to above.
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of fire-extinguishing and lifesaving flies pawl, including mobile jib, buckles and claw hook, described in buckle the one end being arranged at mobile jib, it is used for
Connect rope；Described claw hook is installed on the other end of mobile jib, and claw hook is in for hook fixture, claw hook when being in deployed condition
Convergence state is used for reclaiming；Back-moving spring and locking device, described back-moving spring it is provided with in the junction of described mobile jib and claw hook
For claw hook is maintained at convergence state, described locking device is for being maintained at deployed condition by claw hook.
Further, described locking device is nut, and the medial wall of described nut offers female thread, at mobile jib and pawl
The end that connects of hook offers and the external screw thread of described screw-internal thread fit；When described claw hook is positioned at deployed condition, nut upwards revolves
Tightly downward to offset back-moving spring reset force.
Compared with prior art, the beneficial effects of the utility model are as follows:
1) when for upwards climbing, deployable claw hook also locks, it is simple to upthrow claw hook hook fixture.
2) when being used for declining, can open claw hook and not lock, the holding being hooked in fixture relief continues stress, this
Time can along connect fly pawl rope decline；After decline, payout, grapple, due to non-locking, recovers under action of reset spring
To folded state, now it is difficult to other object of hooking, rope only need to be pulled to take off and fly pawl and be continuing with, it is adaptable to high level is built
Build decline escape.
Accompanying drawing explanation
Fig. 1 is the structural representation that fire-extinguishing and lifesaving described in the utility model flies pawl.
Label declaration in figure: mobile jib 1, buckle 2, claw hook 3, back-moving spring 4, locking device 5.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below
In conjunction with detailed description of the invention, this utility model is expanded on further.
Seeing Fig. 1, a kind of fire-extinguishing and lifesaving described in the utility model flies pawl, including mobile jib 1, buckles 2 and claw hook 3, described
Buckling 2 one end being arranged at mobile jib 1, it is used for connecting rope；Described claw hook 3 is installed on the other end of mobile jib 1, and claw hook 3 is in
For hook fixture during deployed condition, claw hook 3 is in convergence state for reclaiming；In described mobile jib 1 and the junction of claw hook 3
Being provided with back-moving spring 4 and locking device 5, described back-moving spring 4 for being maintained at convergence state, described locking device 5 by claw hook 3
For claw hook 3 is maintained at deployed condition.
Described locking device 5 is nut, and the medial wall of described nut offers female thread, in mobile jib 1 and the company of claw hook 3
Connect end to offer and the external screw thread of described screw-internal thread fit；When described claw hook 3 is positioned at deployed condition, nut upwards screw to
The reset force that the back-moving spring 4 that disappears is downward.
Use principle of the present utility model is as follows:
When for upwards climbing, being opened by claw hook 3 and be at deployed condition, then nut upwards screws and makes it keep
In deployed condition, throwing claw hook 3 then up and make on its hook fixture, fireman climbs to fixture position, the most desirable
Under fly pawl further up throw extension climb.
When being used for declining, not passing through nut locking after can opening claw hook 3, the holding being hooked in fixture relief is persistently subject to
Power state, now can decline along connecting the rope flying pawl；After decline, payout, grapple is due to non-locking, at back-moving spring 4
Return to folded state under effect, be now difficult to other object of hooking, rope only need to be pulled to take off and fly pawl and be continuing with, suitable
Escape is declined for skyscraper.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model
Claimed scope is defined by appending claims and equivalent thereof.
