For achieving the above object, the technical solution adopted in the utility model is:

A kind of novel roller shutter type automatic window screen, comprise the vertical slide rail that is respectively in the window frame left and right sides and be positioned at the retracting device that the slide rail top cross is provided with, two slide rails offer the notch that is used to snap in the gauze edge on the relative side, offer on the housing of retracting device with the corresponding roll of gauze of slide rail notch and close up, be provided with roll shaft in the housing, torsion spring, back shaft and bearing, the housing two ends are provided with end cap, roll of gauze is on roll shaft, one end and roll shaft fix, straining beam is outwards drawn and be provided with to the other end from the mouth that furls of housing, and the slide rail bottom is provided with and the corresponding bindiny mechanism of straining beam.

Described straining beam comprises hand buckle and the location-plate that is connected together mutually, the curved concave shape in the middle part of hand buckle, the top is the U-shaped bayonet socket that opening is used for clamping gauze lower edge up, the bottom is used for the U-shaped bayonet socket of clamping location-plate down for opening, the opening part of U-shaped bayonet socket has relative grab, the rectangular bending-like of location-plate, the external surface of an one right angle walls are provided with and the suitable T shape Ka Dao of hand buckle bottom U-shaped bayonet socket, and the end of another right angle walls has the grab of inside bending.

The middle part of described hand buckle is the semicircle that radian from top to bottom increases gradually on the cross section.

The two ends of described hand buckle are connected with anti-collision block.

Described anti-collision block has a riser, riser one side is provided with and the suitable plate of hand buckle middle profile, anti-collision block also has and the suitable external surface of hand buckle middle profile, form arc clamping seam between the curved surfaces of plate and anti-collision block, the opposite side of riser is provided with the perpendicular side plate that stretches into the slide rail notch.

Offer on the riser of described anti-collision block and the corresponding U-shaped bayonet socket of hand buckle

Described hand buckle and location-plate are integral structure.

Described bindiny mechanism is perpendicular to forms and the corresponding clamp of location-plate grab.

Described straining beam length and slide rail spacing are suitable.

Be fixed with the knob that protrudes in end cap on the back shaft of described roll shaft one end, offer the axis hole that matches with knob on the end cap.

Described gauze one end is connected with roll shaft is bonding.

The both sides heat seal that described gauze stretches into the slide rail notch has the plastics stiffened edge, and the compartment of terrain is provided with a plurality of Sash fasteners on this stiffened edge.

The utility model has been done further improvement to existing straining beam structure, its arc-shaped concave not only had been convenient to finger and is pulled drop-down but also be convenient to the anti-collision block of clamping, and good looking appearance, can be harmonious with the forms profile well, in drop-down and coiling process, straining beam steadily slides between slide rail under the position-limiting action of anti-collision block all the time, skew can not appear, stuck and slide problems such as not smooth, stationarity is good, unique chucking structure has guaranteed that then screen window can precisely firm location after drop-down, when needs are rolled screen window, only need gently one by, roll the ten minutes that operates easy thereby grab just can break away from automatically mutually with clamp.

The utility model is provided with in the rotating shaft of roller shutter type automatic window screen is convenient to the manually external knob of control, need not can adjust by special tool(s) like this in assembling and use, time saving and energy saving, convenient and swift.In addition, handsome in appearance, of a tightly knit structure, sealing performance advantages of higher that the utility model also has, use the attractive in appearance and good sealing effect of safety, the four seasons need not dismounting, not only be convenient to screen window preservation, prolonged application life but also can save memory space, solved the difficult problem that traditional screen window daylighting is bad and deposit.
