Be hinged, the opening of skidding group hook is blocked in one end of the locking tongue, and the other end is fixedly connected with one end of connecting rod, the connecting rod
The other end is connected with active pull rod；
The both ends activity of the active pull rod is enclosed on the terraced column, and the top at the active pull rod both ends is also distinguished
One end of elastomeric element is connected, the other end of the elastomeric element is fixed on the terraced column；
The active pull rod is provided with movable drawstring；
The gag lever post that an end movement is connected for limiting locking tongue with connecting rod is additionally provided with the inside of the terraced column.
Also include guard bar, the guard bar is fixed between two terraced columns, and the connecting rod passes through the guard bar.Protect
Guard bar can be used for the displacement for limiting connecting rod, it can in addition contain protect connecting rod not cause to damage due to arbitrary rock.
The top of the elastomeric element is fixedly connected with spacing ring, and the spacing ring is fixed on the terraced column.It is spacing
The upper end of environmental protection card elastomeric element is fixed, and lower end can drive active pull rod up and down.
The movable drawstring is provided with one, positioned at the centre position of the active pull rod.
The movable drawstring is provided with two, respectively positioned at the both ends of the active pull rod.
The movable drawstring is insulating cord.
The bottom of the movable drawstring is provided with draw ring.Draw ring one is to facilitate pulling activity drawstring, it can in addition contain ensure to live
Dynamic drawstring is sagging.
The beneficial effects of the utility model are：
The utility model does not change rope ladder head and normally mounts work, does not need extra work can just to take turns in mounting
The opening locking of sliding group hook, does not increase extra burden.
Due to the position-limiting action of gag lever post, locking tongue will not be caused unexpectedly to open the opening of skidding group hook.
Movable drawstring can need to be only pulled easily to take rope ladder head from wire when removing rope ladder head from wire
Under, blocking device does not interfere with the normal use of rope ladder head.
Brief description of the drawings
Fig. 1 is this structural representation of the present utility model；
Wherein, 1. skidding groups are linked up with, 2. gag lever posts, 3. connecting rods, 4. guard bars, 5. active pull rods, 6. movable drawstrings, and 7. is horizontal
Bar, 8. terraced columns, 9. springs, 10. spacing rings, 11. locking tongues.
Embodiment：
The utility model is described further with embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of insulating flexible ladder head with blocking device, including two terraced columns 8, the top of terraced column 8
Be respectively provided with skidding group hook 1, multiple cross bars 7 be fixed between two terraced columns 8, the inner side of each terraced column 8 with
The middle part of locking tongue 11 is hinged, and the opening of skidding group hook 1 is blocked in one end of the locking tongue 11, and the other end is fixedly connected
One end of connecting rod 3, the other end of the connecting rod 3 are connected with active pull rod 5；
The both ends activity of the active pull rod 5 is enclosed on the terraced column 8, and the top at the both ends of active pull rod 5 is also
One end of elastomeric element is connected respectively, and the other end of the elastomeric element is fixed on the terraced column 8；It is elastic in the present embodiment
Part selects spring 9, is in former long under spring normal condition, and when needing to open locking tongue 11, spring needs downward elongate.
The active pull rod 5 is provided with movable drawstring 6；
The inner side of the terraced column 8 is additionally provided with the gag lever post 2 that an end movement is connected for limiting locking tongue 11 with connecting rod 3, limits
Determine locking tongue 11 and be connected one end with connecting rod 3 not will be shifted up.
Also include guard bar 4, the guard bar 4 is fixed between two terraced columns 8, and the connecting rod 3 passes through the protection
Bar 4.Guard bar 4 can be used for the displacement for limiting connecting rod 3, it can in addition contain protect connecting rod 3 not caused due to arbitrary rock
Damage.
The top of the elastomeric element is fixedly connected with spacing ring 10, and the spacing ring 10 is fixed on the terraced column 8.
Spacing ring 10 ensures that the upper end of elastomeric element is fixed, and lower end can drive active pull rod 5 up and down.
The movable drawstring is provided with two, respectively positioned at the both ends of the active pull rod 5.Three can also be provided with, such as Fig. 1
Shown in, one positioned at centre, two both ends for being located at active pull rod 5.It is user-friendly.
The movable drawstring is insulating cord.
The bottom of the movable drawstring is provided with draw ring.
The opening locking that locking tongue always links up with skidding group under normal circumstances, when needing that rope ladder head is articulated on wire
When, one end that locking tongue is connected with connecting rod declines, and the other end rises, and the opening of skidding group hook is opened, and wire can passes through
The opening of skidding group hook, skidding group hook can is articulated in wire, and in the presence of elastomeric element, wire is through after linking up with
Locking tongue can automatically reset, the opening locking for again linking up with skidding group.Do not influence normally to work when being articulated on wire,
Or it is articulated in by original method on wire, locking tongue can automatic blocking after having mounted.Convenient use, rope ladder will not be taken off
From wire.
