Description
Technical field
This utility model relates to a kind of aid installing building template drag-line, and more specifically it relates to a kind of mould
Plate drag-line pre-tensioning device.
Background technology
At present, in prior art, Authorization Notice No. is that the Chinese patent document of CN 202467198 U discloses a kind of template
Drag-line pre-tensioning device, including outer sleeve, inner sleeve, crescent moon rule, handle block；Described inner sleeve and outer sleeve are hollow
Cylinder, the internal diameter of described outer sleeve, more than the external diameter of inner sleeve, is provided with bar shape trench hole in the middle part of outer sleeve, the top of inner sleeve is provided with
External screw thread, the bottom of inner sleeve opens bar shape trench hole, and inner sleeve is enclosed in outer sleeve, and inner sleeve top is stretched from the upper end of outer sleeve
Go out；Described handle block is provided with female thread and the external part with inner sleeve is threaded connection, and handle block is provided with handle socket；
Described crescent moon rule are for L shape, and hinged at the corner of crescent moon rule and the notch of inner sleeve bar shape trench hole lower end, crescent moon advises back
While being semicircle, semicircular edge is provided with ratchet, and the another side at crescent moon rule back is flat side.
In prior art, commonly used above-mentioned tensioner carries out stretch-draw to drag-line, but it needs at handle during using
Plug handle in block, then by rotatable handle handle block, inner sleeve is displaced outwardly, thus drag-line is carried out tensioning；On
Stating by the way of rotary handle block makes inner sleeve for linear motion, operate relatively complicated, work efficiency is relatively low.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of easy and simple to handle, work efficiency
High pretensioner for form cable.
For achieving the above object, this utility model provides following technical scheme: a kind of pretensioner for form cable, bag
Including outer sleeve, inner sleeve, described inner sleeve is slidably connected to outer sleeve, and described inner sleeve is the tooth bar with threading chamber, described
Outer sleeve one end has been rotatably connected and tooth bar meshed gears, and described gear is fixedly connected with rotary handle, described inner sleeve
Be arranged over the bar shaped elongated hole communicated with threading chamber, at bar shaped elongated hole connect have crescent moon advise, described outer sleeve be arranged over confession
Crescent moon advises the gathering hole exposed.
By using technique scheme, drag-line is penetrated from one end of outer sleeve and passes from the threading chamber of tooth bar,
And with crescent moon rule, drag-line is blocked so that drag-line cannot retreat；Then directly by the rotary handle rotation being connected on gear
Gear, gear can move along the inwall of outer sleeve by band carry-over bar, and owing to drag-line is fixed in tooth bar by crescent moon rule, tooth bar occurs
Move thus drag-line is strained.Using such scheme, operate easier, work efficiency is higher.
This utility model is further arranged to: described gear includes gear shaft, and described rotary handle includes two mutually
Connecting into the clamping plate of U-shaped, two clamping plate are individually fixed in the two ends of gear shaft, and one end that two clamping plate are connected is fixed with operation
Bar.
By using technique scheme, it is individually fixed in the two ends of gear shaft by two clamping plate, is passing through action bars
Turning gear wheel shaft, gear shaft two ends stress is more uniform, and pinion rotation is more smooth and easy.
This utility model is further arranged to: the sidewall of described gear and the junction of gear shaft are provided with and boss, boss
Conflict with the inwall of outer sleeve.
By using technique scheme, by the conflict of boss and the inwall of outer sleeve thus to avoid gear sidewall direct
Patch touches the inwall in outer sleeve so that there is certain interval between gear sidewall and outer sleeve, the frictional force of generation is less so that
Pinion rotation is more laborsaving.
This utility model is further arranged to: described tooth bar upper end is provided with two and protrudes gathering hole and the connection being parallel to each other
Ear, crescent moon rule are articulated with between two engaging lugs.
By using technique scheme, engaging lug protrudes gathering hole and arranges, and is possible not only to, for connecting crescent moon rule, also may be used
To play the restriction effect of tooth bar displacement, it is to avoid tooth bar is fully removed outer sleeve and causes installation difficulty once again, uses more square
Just.
This utility model is further arranged to: described crescent moon rule include ratchet part and swing part, and swing part connects fork.
By using technique scheme, rotate crescent moon rule by arranging the more convenient operator of fork.
This utility model is further arranged to: the length of described fork is more than the length of gathering hole.
By using technique scheme, it is ensured that fork is in outside gathering hole all the time, without there is swing link end part
Fall into the situation in outer sleeve, it is not necessary to artificially taken out by fork, use more convenient.
In sum, this utility model provides a kind of easy and simple to handle, pretensioner for form cable that work efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Present embodiment discloses a kind of pretensioner for form cable, as it is shown in figure 1, include in outer sleeve 1, outer sleeve 1
Being provided with the chute 15 of rectangular configuration, slidably connect tooth bar 2 in chute 15, tooth bar 2 is provided through wearing along its length direction
Line chamber 3, outer sleeve 1 has gathering hole 5 in chute 15 is opened above, and tooth bar 2 opened above has long with the bar shaped that threading chamber 3 communicates
Hole 4, the edge of bar shaped elongated hole 4 protrudes to gathering hole 5 and is provided with two engaging lugs being parallel to each other 6, logical between two engaging lugs 6
Crossing pin and be rotatably connected to crescent moon rule 7, crescent moon rule 7 include ratchet part 17 and swing part 16, and swing part 16 connects fork 8,
Swinging crescent moon rule 7 by fork 8 can make ratchet part 17 proceed in threading chamber 3；Wherein the length of fork 8 is greater than gathering hole 5
Length, this makes fork 8 fall within all the time outside gathering hole 5.
As in figure 2 it is shown, outer sleeve 1 is positioned at below one end of chute 15 is provided with gear 9, gear 9 engages with tooth bar 2, tooth
Wheel 9 includes gear shaft 10, and the two ends of gear shaft 10 pass outer sleeve 1 and connect in outer sleeve 1 extenal fixation and have clamping plate 13, two
Clamping plate 13 are joined together to form U-shaped structure, the fixing company in one end that two clamping plate 13 are connected towards the other end of gear shaft 10
It is connected to action bars 14；Action bars 14 and clamping plate 13 together constitute the rotary handle 12 of gear 9.
As it is shown on figure 3, the junction of the sidewall of gear 9 and gear shaft 10 is provided with and boss 11, boss 11 is used for and overcoat
The inwall of cylinder 1 is conflicted so that retention gap 18 between the inwall of gear 9 sidewall and outer sleeve 1.
During use, drag-line penetrated from one end of outer sleeve 1 and passes from the threading chamber 3 of tooth bar 2, and advising 7 with crescent moon
Drag-line is blocked so that drag-line cannot retreat；Then directly gear 9, tooth are rotated by the rotary handle 12 being connected on gear 9
Wheel 9 can move along chute 15 by band carry-over bars 2, owing to drag-line 7 is fixed in tooth bar 2 by crescent moon rule, tooth bar 2 be moved thus
Drag-line is strained.Using the present embodiment tension drag-line, operate easier, work efficiency is higher.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, all in this practicality
Within novel design concept, any modification, equivalent substitution and improvement etc. made, should be included in protection of the present utility model
Within the scope of.
