Description

Self-locking flies pawl

Technical field

The utility model relates to a kind of auxiliary equipment technical field, especially self-locking of climbing and crossing over gully and fliesPawl.

Background technology

Field exploration, geologic prospect, disaster area rescue etc. are all advanced in region with a varied topography, have a lot of gullies to needDegree of flying, also has some hillside to need to climb, and when gully degree of flying or hillside are climbed, generally rope need be hung over to gullyOpposite or top, hillside, defensive position is grabbed rope and is moved, and when lanyard rope, afterbody is hung to rope and is flying pawl class design workTool is got, and fly pawl and pierce trunk and fix, but the conventional anti-receding device that flies pawl is that head is established little fallingThorn, retaining grip point is little, retaining effect is limited, if hangnail is too large, can affect fly pawl pierce trunk deeplyDegree, affects fastening strength.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides self-locking to fly pawl, comprises and flyingPawl body, the lock banking stop that falls, flexure strip, flies pawl body centre for flying claw bar, and tail ring is established in lower end, and cone is established in upper endShape pawl head, pawl point is established in taper pawl head upper end, and inner plane is established in left side, inside establishes pit, and pit bottom is established screw,Indent straight trough is established in upper end, in indent straight trough, establishes down lock banking stop, and upper end right-hand member is established axis hole, and left end is established screw two,In axis hole, screw two, establish axle screw and be connected with the upper end of falling lock banking stop, the flexure strip of arc is established in the inner side of falling lock banking stop,The bottom of flexure strip is spirally connected with the screw of screw and pit bottom, injects after trunk, locks card in automatically insideShrink, be beneficial to self-locking and fly pawl and inject trunk and deepen, self-locking flies that pawl is reverse to be pulled when stressed, and locking card in can be fromMove out, retaining self-locking, improves retaining intensity and fastening strength greatly, and hand is grabbed when tail ring lanyard swashes to be increasedSecurity.

For achieving the above object, the technical solution of the utility model is: self-locking flies pawl, comprise fly pawl body,Fall lock banking stop, flexure strip, described in fly in the middle of pawl body as flying claw bar, tail ring is established in lower end, taper pawl is established in upper endHead, pawl point is established in described taper pawl head upper end, and inner plane is established in left side, inside establishes pit, and described pit bottom is established spiral shellHole, indent straight trough is established in upper end, in described indent straight trough, establishes down lock banking stop, and upper end right-hand member is established axis hole, and left end is establishedScrew two, establishes axle screw in described axis hole, screw two and is connected with the upper end of falling lock banking stop, in described lock banking stopSide is established the flexure strip of arc, and the bottom of described flexure strip is spirally connected with the screw of screw and described pit bottom.

Further arrange, in described tail ring, establish annular distance.

The beneficial effects of the utility model are: inject after trunk, lock card in and automatically inwardly shrink, be beneficial to certainlyLock flies pawl and injects trunk and deepen, and self-locking flies that pawl is reverse to be pulled when stressed, and locking card in can automatically spring open, retainingSelf-locking, improves retaining intensity and fastening strength greatly, and hand is grabbed increases security when tail ring lanyard swashes.

Detailed description of the invention

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is done further concreteExplanation.

As shown in Figure 1 to 4, self-locking flies pawl, comprise fly pawl body 1, fall lock banking stop 2, flexure strip 3,Described pawl body 1 centre that flies is for flying claw bar 101, and tail ring 103 is established in lower end, and taper pawl head 102, institute are established in upper endState taper pawl head 102 upper ends and establish pawl point 104, inner plane 105 is established in left side, inside establishes pit 106, described pitScrew 1061 is established in 106 bottoms, and indent straight trough 1023 is established in upper end, in described indent straight trough 1023, establishes down lock banking stop2, upper end right-hand member is established axis hole 1021, and left end is established screw 2 1022, in described axis hole 1021, screw 2 1022If axle screw 201 with fall lock banking stop 2 upper ends and be connected, the flexure strip 3 of arc is established in described lock banking stop 2 inner sides,The bottom of described flexure strip 3 is spirally connected with screw 1062 and the screw 1061 of described pit 106 bottoms, this realityInject after trunk with novel, lock card 2 in and automatically inwardly shrink, be beneficial to self-locking and fly pawl and inject trunk and deepen,Self-locking flies that pawl is reverse to be pulled when stressed, and locking card 2 in can automatically spring open, and retaining self-locking improves retaining greatlyIntensity and fastening strength, hand is grabbed increases security when tail ring 103 lanyards swash.

In described tail ring 103, establish annular distance 1031.

More than show and described general principle of the present utility model and principal character, and of the present utility modelAdvantage. The technical staff of the industry also understands, and the utility model is not subject to the restriction of above-mentioned case study on implementation, above-mentionedThat in case study on implementation and description, describes just illustrates principle of the present utility model, is not departing from the utility modelUnder design category prerequisite, the utility model also has various changes and modifications, and these changes and improvements all fall intoWithin the scope of claimed the utility model, the claimed scope of the utility model is by appended claimsAnd equivalent defines.
