The end of the rotating shaft is provided with a driven sprocket, and the driven sprocket is connected to the driving device;

The venetian roller blinds are sequentially connected by parallel hollow louver strips through connectors, and the adjacent end surfaces of adjacent hollow louver strips are respectively provided with corresponding connector insertion holes to cooperate with the connectors. Both ends of the connectors are displaceably nested in the hollow louver strips, and at least two sets of equal-length connectors are provided for each adjacent two hollow louver strips;

The side of the window frame is provided with a positioning column, and the positioning column is provided with a positioning pin matched with the hollow slats, and the positioning column is rotatably connected to the window frame.

According to the rolling shutter security window described in the utility model, the recommended connectors are H-shaped nails.

The hollow louver strips are the same profile, and the adjacent upper and lower end surfaces of the hollow louver strips are grooves and protrusions that cooperate with each other.

Further, when the hollow louver slats are tensioned, the length of the H-shaped nails exposed on the hollow slats is the same as the height of the hollow slats.

Furthermore, the adjacent upper and lower end surfaces of the hollow louver strips of the same profile form mutually matching grooves and the sum of the heights of the protrusions is exactly half of the height of the hollow louver strips.

Still further, the distance between adjacent positioning pins on the positioning column is the same as the height of the hollow louver strip.

Preferably, the hollow louver strips are provided with positioning holes that cooperate with positioning pins.

The driving device described in the utility model is a motor capable of forward rotation and reverse rotation, and the driven sprocket is connected with the output shaft of the motor.

The driving device described in the utility model can also be a handle, and the handle is fixed with the driving sprocket, and the driving sprocket is connected with the passive sprocket through a steel chain.

The technical effect of the utility model is embodied in that: the hollow louver slats can be completely closed, and the positioning pin can also be used to fix the position to keep the security window ventilated and light-transmitting; the operation is convenient, and it is convenient to open and escape.

(5) Specific implementation methods

The utility model will be further described below in conjunction with the accompanying drawings, but the technical parameters involved in the scheme cannot be interpreted as limitations to the utility model.

Example 1

A rolling shutter-type security window, comprising a window frame, a shutter, and a rotating shaft (3), the upper end of the shutter is fixedly connected to the shaft, and the two sides of the window frame are respectively provided with U-shaped grooves that cooperate with the shutter (1). The end of the rotating shaft is provided with a driven sprocket (4), and the driven sprocket is connected with the driving device; the driving device is: a handle (7), the handle is fixed with the driving sprocket, and the driving sprocket (8 ) is connected with the passive sprocket wheel by a steel chain (5).

The venetian roller blinds are connected by parallel hollow louver strips (2) sequentially through H-shaped nails (9), and the adjacent end faces of adjacent hollow louver strips are respectively provided with corresponding connectors extending into holes (6 ) cooperate with the H-shaped nails, and the two ends of the H-shaped nails are displaceably nested in the hollow louver strips, and at least two sets of equal-length connectors are provided for every two adjacent hollow louver strips. The hollow louver strips are the same profiles, the adjacent upper and lower end surfaces of the hollow louver strips are grooves and protrusions that cooperate with each other, and the H-shaped nails are exposed in the hollow when the hollow louver strips are tensioned. The length of the louver strips is the same as the height of the hollow louver strips; the adjacent upper and lower end surfaces of the hollow louver strips of the same profile form mutually matching grooves and the sum of the height of the protrusions is exactly half the height of the hollow louver strips.

The side of the window frame is provided with a positioning post (10), and the positioning post is provided with a positioning pin (11) matched with the hollow slats, and the positioning post is rotatably connected to the window frame. The distance between the adjacent positioning pins on the positioning column is the same as the height of the hollow louver strip, and the hollow louver strip is provided with a positioning hole (12) matched with the positioning pin.

When closing the security window, turn the handle to lower the roller blind; if you want to completely close the security window and make it opaque, put it down completely, and when the bottom hollow slat touches the bottom frame of the window frame, the upper hollow slat continues Moving down, the grooves and protrusions of the adjacent hollow louver strips are matched, and one after another are sequentially superimposed to form a closed window, and the positioning column is rotated so that the positioning pins and the positioning holes on the hollow slats of the louver. If you want to leave a gap and transmit light in the security window, when the bottommost hollow slat plate touches the bottom frame, turn the positioning column to make the positioning pin and the positioning hole on the hollow slat plate. Function, the hollow slats on the H-nail roller blinds leave gaps between the adjacent hollow slats.

When the security window is to be put away, the handle is reversely turned, and the roller blind is rolled up with the rotation of the rotating shaft.
