Description

a roller blind

technical field

The invention relates to a rolling shutter structure, in particular to a rolling shutter applied to a rolling door or a rolling window.

Background technique

The rolling shutter door is a kind of door that is connected in series with multi-joint movable doors, and in a fixed slideway, the door is rotated up and down centered on the scroll above the door. Rolling shutter doors are suitable for commercial facades, garages, shopping malls, hospitals, factories and mines and other public places or residences. It is especially suitable for some occasions where the door opening is large and it is inconvenient to install the ground door body, such as garage doors, fireproof shutter doors of shopping malls, hangar doors, etc. The shutter door can be opened conveniently and quickly.

The main part of the door body or form of a rolling door or a rolling window is a rolling shutter sheet. The following defects generally exist in the structure of the traditional rolling shutter sheet: (1), the rolling shutter sheet is not fully modularized, It brings a lot of inconvenience to production, construction, installation and maintenance; (2), when rolling or unwinding the roller blind, the friction between the curtains is large, which makes the noise loud; (3), rolling The main structure of the curtain sheet is made of metal material, which has poor thermal insulation performance when ensuring the high strength of the roller blind sheet; (4), the sides of the roller blind sheet are smooth and flat, and the curtain itself The bending resistance is poor, and the wind resistance performance cannot be guaranteed during use, and the blinds are prone to mutual extrusion and deformation; It is easy to get stuck in the guide rail when rolling or unwinding, and the side buckle is made of plastic, which has a short service life.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a rolling shutter with an ingenious and reasonable structure, which has low friction when winding or unwinding, low noise, and smooth rolling and unwinding operation , The connection is safe and reliable, and it has good compressive strength, bending resistance and torsional strength, and has excellent thermal insulation performance.

According to the technical solution provided by the present invention, the rolling shutter comprises a curtain body, the curtain body protrudes upwards with an upper hook, and the lower part is recessed to form a lower hook, and the upper hook can be buckled with the lower hook of the adjacent curtain. One end of the upper hook on the curtain body is provided with a notch, and the lower hook is provided with a slot corresponding to the notch, and the notch and the slot are arranged at the same end of the same curtain body. When the upper hook on the sheet is fastened and connected with the lower hook on the other curtain sheet, the end of the upper hook that is provided with a gap is blocked by the slot.

As a further improvement of the present invention, the upper hook and the lower hook are large arc structures that cooperate with each other. The concave arc surface design of the upper hook, the lower hook and the curtain body is located on the same arc surface. The arc end of the upper hook is provided with an upper protrusion, and the end of the lower hook is provided with a lower protrusion, and the upper protrusion and the lower protrusion can be locked and fixed with each other. At least one bead is provided on the convex arc surface of the curtain body, and the number of bead is preferably 2-3. The interior of the curtain body is provided with a cavity, and the cavity is filled with heat-insulating material, and the heat-insulating material preferably adopts an environmentally friendly polyurethane heat-insulating foam material not containing hydrocarbon fluoride.

The advantages of the knot of the present invention are: (1), through the design of the upper hook and the lower hook provided on the curtain body, the curtains are hooked to form the whole door body or window structure, so that the curtains can realize industrialization Production, production, installation, construction and transportation are more convenient. (2) The notch and the card groove structure cooperate with each other, so that the two curtains will not slide relative to each other, replacing the traditional side buckle at the end of the curtain, improving the service life of the curtain and avoiding the gap between adjacent curtains. The slippage of the connection. (3) The upper hook and the lower hook of the adjacent curtain are large circular arc structures that cooperate with each other, which increases the contact area of the connection between the curtains, so that when the curtains are rolled or unrolled, the gap between the curtains The friction between them is small and the noise is low. (4) The upper hook, the lower hook and the concave arc surface of the curtain body are located on the same arc surface, which makes the roller blind retractable and unwinding run smoothly, and the rolling is more compact, avoiding mutual extrusion and deformation of the curtains, and smooth operation shock. (5) The upper protrusion at the end of the arc of the upper hook and the lower protrusion at the end of the lower hook can be locked and fixed, further avoiding the falling off of the connection between adjacent curtains when rolling or unwinding. (6) The convex arc surface of the curtain body is provided with pressure ribs, which enhances the bending resistance of the curtain, improves the wind resistance of rolling shutter doors and windows, and also improves the compressive strength, bending resistance and torsional strength of the curtain . (7) The foam material is accommodated in the cavity of the curtain sheet, which fully utilizes the rigidity of the metal curtain sheet and the thermal insulation performance of the foam material.

Detailed ways

As shown in the figure, the present invention includes a curtain body 1, the curtain body 1 protrudes upwards with an upper hook 2, and the lower part is recessed to form a lower hook 6, and the upper hook 2 can be buckled with the lower hook 6 of the adjacent curtain The upper hook 2 and the lower hook 6 are a large circular arc structure that cooperates with each other. The large circular arc structure can increase the contact area of the connection between the curtains, so that when rolling or unwinding, the distance between the curtains Small friction and low noise; in order to make the curtain more compact when rolling up, run smoothly, reduce friction, avoid extrusion and deformation between the curtains, and run without impact, the upper hook 2, the lower hook 6 and the curtain body 1 The concave arc surface 4 is located on the same arc surface.

As shown in Figure 3, a notch 10 is provided at one end of the upper hook 2 on the curtain body 1, and a notch 11 corresponding to the notch 10 is provided on the lower hook 6, and the notch 10 and the notch 11 are arranged on the same curtain At the same end of the body 1, when the upper hook 2 on one curtain is fastened and connected with the lower hook 6 on the other curtain, the end of the upper hook 2 with the notch 10 is blocked by the slot 11, so that the two connected curtains The sheet bodies 1 will not slide relative to each other. This structure replaces the traditional side buckle at the end of the sheet, improves the service life of the sheet and avoids the slipping of the connection between adjacent sheets.

As shown in Figure 1, an upper protrusion 3 is provided at the arc end of the upper hook 2, and a lower protrusion 7 is provided at the end of the lower hook 6. When the adjacent curtains rotate to a certain angle, the upper protrusion 3 and the lower protrusion 7 are locked and fixed to each other, further preventing the connection between adjacent curtains from coming off.

As shown in Figures 1 and 3, a certain number of ribs 9 are provided on the convex arc surface 8 of the curtain body 1, and the ribs 9 can be used to enhance the bending resistance and wind resistance of the curtain, and at the same time effectively avoid The curtains are extruded and deformed by each other. The interior of the curtain body 1 is provided with a cavity, and the cavity is filled with an insulating material 5. The insulating material 5 is preferably an environmentally friendly polyurethane heat-insulating foam material that does not contain hydrocarbons at all, so as to ensure that the curtain has good heat preservation. performance and safety and environmental performance.
