Abstract
The utility model relates to a sunshade blind for a telescopic-boom sling cart. The sunshade blind comprises a shell, a reel and a roller blind, wherein the reel is rotationally installed in the shell, and the roller blind is wound on the reel. The shell is provided with a blind outlet, the roller blind comprises a fixed end and a stretching end, a central spindle is fixedly installed in the reel, a return torsional spring is installed on the outside of the central spindle, one torsional arm of the return torsional spring is fixedly connected with the central spindle, and the other torsional arm of the return torsional spring is fixedly connected with the reel. A gear is fixedly installed at one end portion of the reel, the shell is provided with a clamping hook used for blocking and limiting rotation of the gear, the middle portion of the clamping hook is hinged to the shell, the shell is further provided with a limiting block and a return spring, the limiting block can limit rotation of the clamping hook, and the return spring can enable the clamping hook to return to block and limit the gear. When the roller blind of the sunshade blind is pulled downwards, the effect that stopping is achieved once pulling is conducted can be achieved. When the roller blind needs to be folded, only a pull rope needs to be pulled, and namely the roller blind is automatically folded under the action of torsional force of the return torsional spring. The folding speed of the roller blind is high, operation is simple, and using is very convenient.
Description
Technical field
The utility model relates to a kind of abat vent, refers to a kind of abat vent for the telescopic arm sling cart especially.
Background technology
The telescopic arm sling cart is used for outdoor work more, is the eyes of protection human pilot and the temperature in the reduction driver's cabin, and regular meeting arranges abat vent in the driver's cabin.The abat vent of existing sling cart is to make roller shutter launch by the external part that pulls moving roller shutter, and will pack up roller shutter the time, then needs to spur stay cord roller shutter is packed up slowly, and the speed that roller shutter is packed up is slow, uses comparatively trouble; When human pilot is badly in need of seeing the scenery of roller shutter shield portions, use existing abat vent then possible because can not pack up and the situation of causing danger fast.
Summary of the invention
The utility model provides a kind of abat vent for the telescopic arm sling cart, and it is slow that the roller shutter that the abat vent of existing telescopic arm sling cart assembling exists is packed up speed, awkward problem.
The utility model adopts following technical scheme:
A kind of abat vent for the telescopic arm sling cart, comprise housing, be located at the spool in the housing and be wound in roller shutter on this spool rotationally, this housing is provided with curtain outlet, and this roller shutter comprises the fixed end of this spool that is fixedly connected and runs through this curtain outlet and extends to this hull outside external part; The said reel internal fixation is provided with mandrel, and this mandrel outer cover is provided be used to the reduction torsion spring of packing up above-mentioned roller shutter, and of this reduction torsion spring turns round arm this mandrel that is fixedly connected, and another turns round arm this spool that is fixedly connected; This spool one end is fixed with gear, this housing is provided with the trip that rotates for this gear of card limit, this trip one end is sticked between adjacent two double wedges of this gear, the other end is provided with stay cord, this trip middle part is articulated in this housing, and this housing also is provided with the limited block that limits this trip rotation and can makes this trip be reset to the back-moving spring of this gear of card limit.
Further with improvement, above-mentioned roller shutter is fixed with and can prevents that above-mentioned external part from entering the cross bar of above-mentioned enclosure interior.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: can realize drawing the effect of ending when the roller shutter of abat vent of the present utility model pulls down, and only need spur this stay cord when packing up this roller shutter, this roller shutter is namely packed up under the twisting force of reduction torsion spring automatically, the speed that roller shutter is packed up is fast, and is simple to operate, uses convenience very.

The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of abat vent for the telescopic arm sling cart, comprise housing 1, be located at the spool 11 in the housing 1 and be wound in roller shutter 12 on this spool 11 rotationally, this housing 1 is provided with curtain outlet 10, and this roller shutter 12 comprises the fixed end 121 of this spool 11 that is fixedly connected and runs through this curtain outlet 10 and extends to this housing 1 outside external part 122; Said reel 11 internal fixation are provided with mandrel 13, and these mandrel 13 outer cover are provided be used to the reduction torsion spring 14 of packing up above-mentioned roller shutter 12, and of this reduction torsion spring 14 turns round arm this mandrel 13 that is fixedly connected, and another turns round arm this spool 11 that is fixedly connected; These spool 11 1 ends are fixed with gear 111, this housing 1 is provided with the trip 15 that rotates for this gear 111 of card limit, these trip 15 1 ends are sticked between adjacent two double wedges of this gear 111, the other end is provided with stay cord 16, these trip 15 middle parts are articulated in this housing 1, and this housing 1 also is provided with the limited block 17 that limits these trip 15 rotations and can makes this trip 15 be reset to the back-moving spring 151 of this gear 111 of card limit.
In addition, above-mentioned roller shutter 12 is fixed with and can prevents that above-mentioned external part 122 from entering the cross bar 18 of above-mentioned housing 1 inside.Can also be provided with by guiding mechanism in the driver's cabin of sling cart, the downward operation that launches or upwards pack up can be done along this guiding mechanism in the two ends of this cross bar 18.
Spur the cross bar 18 of abat vent of the present utility model downwards, roller shutter 12 namely moves downward and launches along with cross bar 18, when stopping drag cross bar 18, trip 15 is under the effect of back-moving spring 151, one end end namely is sticked between adjacent two double wedges of this gear 111, and trip 15 blocks gear 111, makes that gear 111 can be under the torsion of reduction torsion spring 14 and rotate, spool 11 also stops operating immediately, thereby realizes namely drawing the effect of namely ending; Pulling connects the stay cord 16 of trip 15, one end end of trip 15 is namely left gear 111 and gear 111 is not produced restriction, twisting force lower winding shaft 11 at reduction torsion spring 14 namely rotates, and then makes coiling be wound in spool 11, thereby realizes the effect that roller shutter 12 brakings are packed up; The speed that this roller shutter 12 is packed up is fast, simple to operate, uses convenience very.
