Abstract
The utility model belongs to the field of roller shutters and particularly relates to an abat vent. The abat vent comprises a roll barrel shell, slide rails, cord fabric and a bottom beam, wherein the slide rails are arranged on the left side and the right side of the lower portion of the roll barrel shell, the number of the slide rails is two, the abat vent is collected in the roll barrel shell in a rolling mode, the tail end of the abat vent is connected with the bottom beam, and two ends of the bottom beam are located in the slide rails. The abat vent is characterized by further comprising a tension device. The tension device comprises constant force plate springs and constant force plate spring outer shells, wherein the constant force plate spring outer shells are fixed on the lower portion of the slide rails, the constant force plate springs are fixed in the constant force plate spring outer shells, and the tail end of each of the constant force plate springs extends out from each of the constant force plate spring outer shells and is fixedly connected with the bottom beam. The abat vent is simple in structure and strong in practicability.
Description
Technical field
The utility model belongs to the roller shutter field, relates in particular to a kind of abat vent.
Background technology
Abat vent has the effect that keeps the sun off, and it provides a comfortable environment of having a rest to people.Abat vent comprises reel shell, slideway, cord, bottom girder, fixedly connected with bottom girder in the lower end of cord, cord both can rolling in the reel shell, also can pull out from the reel shell, cord relies on bottom girder gravity and conducts oneself with dignity and hangs on the bottom of reel shell, though the two ends of bottom girder are positioned at slideway, but do not fix with slideway, when cord is subjected to time spent of doing of wind-force, cord and bottom girder are swung easily, influence attractive in appearance and use.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of abat vent, comprise the reel shell, slideway, cord, bottom girder, the left and right sides of described reel shell bottom is respectively arranged with described slideway, the quantity of described slideway is two, described cord furls in described reel shell and its end joins with described bottom girder, the two ends of described bottom girder lay respectively in the described slideway, it is characterized in that: also comprise tensioning apparatus, described tensioning apparatus comprises constant force flat spring and constant force flat spring shell, described constant force flat spring shell is fixed in the bottom of described slideway, described constant force flat spring is positioned at described constant force flat spring shell, and the end of described constant force flat spring stretches out described constant force flat spring shell and fixedlys connected with described bottom girder.
Be provided with axle in the described constant force flat spring.
The beneficial effects of the utility model are: set up tensioning apparatus in the utility model, constant force flat spring in the tensioning apparatus applies more constant pulling force to bottom girder, thereby makes bottom girder be fixed on constant position, and cord and bottom girder are difficult for swing, remain at flattened state, both artistic and practical; The outside of constant force flat spring is provided with constant force flat spring shell, and constant force flat spring shell can play the effect of protection constant force flat spring, the long service life of constant force flat spring; Be provided with axle in the constant force flat spring, constant force flat spring telescopic action is strong; The utility model provides abat vent a kind of simple in structure, practical.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic side view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure, 1-reel shell, 2-slideway, 3-cord, 4-bottom girder, 5-tensioning apparatus, 6-constant force flat spring, 7-constant force flat spring shell, 8-axle.
Embodiment 1
Shown in Fig. 1-2, the left and right sides of reel shell 1 bottom is respectively arranged with slideway 2, the quantity of slideway 2 is two, cord 3 furls in reel shell 1 and it terminally joins with bottom girder 4, the two ends of bottom girder 4 lay respectively in the slideway 2, tensioning apparatus 5 comprises constant force flat spring 6 and constant force flat spring shell 7, constant force flat spring shell 7 is fixed in the bottom of slideway 2, constant force flat spring 6 is positioned at constant force flat spring shell 7, the end of constant force flat spring 6 stretches out constant force flat spring shell 7 and fixedlys connected with bottom girder 4, is provided with axle 8 in the constant force flat spring 6.
Make use-case
Abat vent is the time spent not, and cord 3 is furled in reel shell 1, and constant force flat spring 6 is in extended state; When using abat vent, cord 3 to be pulled out from reel shell 1, constant force flat spring 6 is in contraction state.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
