Abstract
The utility model relates to a shutter upper rail. The main body of the utility model is a long slot body at the upper part; wherein the slot body bottom and back side wall are in flat shapes, while the front side wall is a bent plate with a bent angle protruding forward; and two sides of the top opening are provided with a horizontal top plate for connecting the front side wall and the back side wall; and the top plate edge is provided with a hem extending into the slot; the slot bottom is provided with a plurality of reinforcing ribs positioned in the slot, generally two in number; the reinforcing ribs take the bar shapes extending vertically; a hole used for providing a shutter pull rope and a rotational rod is arranged at the half lower part of the bent plate on the front side wall of the slot body. The utility model has beautiful outer form and high bending resistant intensity and is not easy to be damaged; and the obstruction and collision to the shutter leaves by the pull rope and rotationally rob are avoided.
Description
Technical field
The utility model relates to rail on a kind of shutter.
Background technology
The main body of rail is the elongated slot body of upper opening on the existing shutter, and cell body bottom and both sides, front and back sidewall are tabular, the horizontal edge of sidewall before and after the open top both sides are provided with and connect, and the defective of this structure is that flexural strength is not high, is easy to damage.
The utility model content
For overcoming the above-mentioned defective of prior art, the utility model provides rail on a kind of shutter, and the flexural strength height of rail is not fragile on this shutter.
The technical scheme that the utility model overcomes the above-mentioned defective of prior art is: the main body of rail is the elongated slot body of upper opening on the shutter, the cell body bottom is tabular, be provided with some reinforcing ribs that are positioned at groove, the quantity of described reinforcing rib can be two generally, is the strip of longitudinal extension.
Because the utility model is provided with reinforcing rib in the cell body bottom, has improved whole flexural strength, has prolonged application life.
Description of drawings
Fig. 1 is the schematic perspective view of rail main body on the shutter that provides of the utility model;
Fig. 2 is a rail body cross-section structural representation on the shutter corresponding with Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the main body of rail is the elongated slot body of upper opening on the shutter that the utility model provides, and cell body bottom 4 is tabular, is provided with some reinforcing ribs 5 that are positioned at groove.
The quantity of described reinforcing rib 5 can be two generally, is the strip of longitudinal extension.
The rear wall 3 of described cell body can be tabular, the horizontal top plate 2 of sidewall 6,3 before and after open top 7 both sides can be provided with and connect, and front side wall 6 can be the flap that has a knuckle to front protrusion, this contour structures is more attractive in appearance, also is more convenient for using.
The edge of the horizontal top plate 2 of described cell body opening 7 both sides can be provided with the vertical flanging 1 that extends in groove, these vertical flangings 1 can play booster action equally.
The Lower Half of described front side wall 6 flaps can be provided with the hole that is used to install drawing cord for louver window and bull stick, because front side wall 6 is to front protrusion, make between stay cord and bull stick the blade and maintain certain distance, avoided stay cord and bull stick when operation to the obstruction of blade with break with shutter.
