Front inner between lower handle 2, unclamps upper handle 1, and tensioning torsion spring 4 can promote upper handle 1 to rotate up, pass through tensioning torsion spring
4 can give upper handle 1 and lower handle 2 to provide tension force.
The afterbody of upper handle 1 is provided with the second rotary shaft 7 by installing plate 6, and the tight torsion spring of the back of the body is arranged with the second rotary shaft 7
8, back of the body tightening position can be provided to upper handle 1 and lower handle 2 by carrying on the back tight torsion spring 8, baffle plate is fixed with the side of installing plate 6
9, the windup-degree for carrying on the back tight torsion spring 8 can be both limited by baffle plate 9, the anglec of rotation of upper handle 1, namely linkage can also be limited
The stroke of bar 10.Upper handle 1 is unclamped, the tight end of the back of the body for carrying on the back tight torsion spring 8 is reversed forward, is stuck in the detent 17 on lower handle 2,
Prevent upper handle 1, gangbar 10 and dead bolt 14 from moving again, that is, ensure that shank 5 stops that suspension ring do not eject elevator.
Be fixed with shank 5 in the bottom of lower handle 2, i.e. the bottom of shank 5 and lower handle 2 is welded, in shank 5 activity set
There is the gangbar 10 moved up and down in shank 5, the front end of upper handle 1 is provided with upper handle groove 11, and the top of gangbar 10 is set
Have with upper handle groove 11 be engaged by clamping symmetrical grooves 12, by the grafting of two grooves can make upper handle 1 move when band
Dynamic gangbar 10 moves up and down in shank 5, release handle, and upper handle 1 drives gangbar 10 in the presence of tensioning torsion spring 4
Descending, gangbar 10 promotes dead bolt 14 to stretch out shank 5, and thus dead bolt 14 and lower handle 2 block the upper hanger of elevator jointly.
Linkage groove 13 is provided with the bottom of gangbar 10, is provided with what is be rotatablely connected with gangbar 10 in the groove 13 that links
Dead bolt 14, offers elongated slot 15 on shank 5 positioned at the position of dead bolt 14, and the elongated slot 15 that dead bolt 14 can pass through shank 5 stretches out shank
5.Shank 5 is inserted in the pin-and-hole of elevator and is inserted into bottom, release handle, upper handle 1 drives connection in the presence of tensioning torsion spring 4
Lever 10 is descending, and gangbar 10 promotes dead bolt 14 to stretch out shank 5, and thus dead bolt 14 and lower handle 2 block hanging oneself for elevator jointly
Ear.
3rd rotary shaft 16 is installed in the linkage groove 13 of the bottom of gangbar 10, dead bolt 14 is arranged on the 3rd rotary shaft
On 16, and rotated around the 3rd rotary shaft 16.
The one end for carrying on the back tight torsion spring 8 is in contact with the afterbody of upper handle 1, and the other end for carrying on the back tight torsion spring 8 is arranged on lower handle 2
In detent 17.When carrying on the back tight torsion spring 8 and reversing, the other end can be stuck in the detent 17 on lower handle 2, make upper handle 1,
Gangbar 10 and dead bolt 14 can not move again, that is, ensure that shank 5 stops that suspension ring do not eject elevator.
Job Operations personnel hold upper handle 1 of the present utility model and lower handle 2 when in use, outwards push the tight torsion spring of the back of the body aside
8, upper handle 1 and lower handle 2 are compressed, drives the gangbar 10 of front portion up using lever principle upper handle 1, by under gangbar 10
Dead bolt 14 in portion's linkage groove 13 is taken in shank 5.Shank 5 is inserted in the pin-and-hole of elevator and is inserted into bottom, unclamps upper handle 1
With lower handle 2, upper handle 1 drives gangbar 10 descending, gangbar 10 promotes dead bolt 14 to stretch out in the presence of tensioning torsion spring 4
Shank 5, thus dead bolt 14 and lower handle 2 block the upper hanger of elevator jointly.The tight end of the back of the body for carrying on the back tight torsion spring 8 simultaneously is reversed forward,
It is stuck in the detent 17 on lower handle 2, prevents upper handle 1, gangbar 10 and dead bolt 14 from moving again, that is, ensures that shank 5 hinders
Gear suspension ring do not eject elevator.
As long as shank 5 is inserted elevator pin-and-hole by the utility model, dead bolt 14 not in place does not flick, and can remind operating personnel must
It must insert in place.After insertion in place, upper handle 1 and lower handle 2 are unclamped, dead bolt 14 stretches out shank 5 from elongated slot 15 and flicked, safety
Pin can pin suspension ring hanger.The coupling mechanism force of dead bolt 14 is supported by the positioning of the elastic force and the tight torsion spring 8 of the back of the body of tensioning torsion spring 4,
Two torsion springs are mounted in the inside of upper handle 1 and lower handle 2, as long as safety pin is inserted into position, even if elevator is pacified when playing lower tubular column
Full pin, which touches, to be suspended to elsewhere, and safety pin will not be also pulled out, and " single-ring " or the bilateral ejection elevator thing of suspension ring would not occur
Part, so as to prevent the generation of suspension ring ejection elevator event.This kind of tongue locking-type elevator pin dependable performance, has considerably increased down tube
Post construction safety reliability.
The utility model is not limited to above-mentioned embodiment, in those skilled in the art's possessed knowledge,
It can also be made a variety of changes on the premise of the utility model aims are not departed from, the content after change still falls within the utility model
Protection domain.
