DETAILED DESCRIPTION

[0022] The technical scheme of the utility model will be described clearly and completely below in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Reference Figures 1 to 6 The utility model provides a kind of technical scheme: a kind of electric rolling shutter door, including rolling shutter door plate 5, rolling shutter door plate 5 is connected by rotating by multiple strip-shaped plates, strip-shaped plate is aluminum alloy plate, color steel plate or stainless steel plate etc., plate is connected by hinge or pivot between plate, both sides of rolling shutter door plate 5 are movably placed in guide groove 4, in the process of actual use, guide groove 4 is installed on the both sides of door frame, so that the both sides of rolling shutter door plate 5 can be slidably installed in guide groove 4.

[0024] As Figure 2 Shown, two guide grooves 4 top side are respectively equipped with support arm 11, support arm 11 is vertically arranged on strip-shaped seat 3 close to one end of rolling shutter door plate 5, strip-shaped seat 3 bottom is connected with support arm 11 by reinforcing frame 12, support arm 11, strip-shaped seat 3 and support arm 11 are triangularly distributed, the strip-shaped seat 3 set is fixed on wall body by expansion bolt, so that support arm 11 can be stably fixed.

[0025] Further, the ends of the two support arms 11 are provided with a winding device, and the top of the rolling shutter door plate 5 is connected to the winding device. Figure 2 And Figure 4As shown, the winding device includes a drive rod 8 located between two support arms 11, with both ends of the drive rod 8 rotatably connected to the support arms 11. During installation, one end of the drive rod 8 is connected to the gearbox 2, which is connected to the fixed plate 7 mounted on the support arm 11. A motor 14 is installed on the input end of the gearbox 2. During use, the motor 14 drives the drive rod 8 to rotate, thereby causing the drive rod 8 to drive the roller shutter door panel 5 to wind.

[0026] like Figure 3 As shown, to facilitate the winding of the roller shutter door panel 5 onto the drive rod 8, multiple winding support wheels 15 are installed on the drive rod 8. These multiple winding support wheels 15 are connected by a strip support plate 6, and the top of the roller shutter door panel 5 is rotatably connected to the strip support plate 6. It should be noted that the strip support plate 6 strengthens the top of the roller shutter door panel 5, preventing deformation. During winding, all the force applied by each winding support wheel 15 acts on the strip support plate 6.

[0027] Furthermore, such as Figure 2 As shown, the winding device is located slightly above the top of the guide groove 4. When winding the roller shutter door panel 5, the roller shutter door panel 5 will inevitably bend. Therefore, a support shaft 13 is provided between the two support arms 11. The two ends of the support shaft 13 are respectively rotatably set in the mounting base 18. The two mounting bases 18 are respectively located at the support arms 11, and the mounting bases 18 are detachably connected to the support arms 11. Multiple guide wheels 17 are installed on the support arms 11.

[0028] like Figure 3 As shown, the top of the roller shutter door panel 5 actually passes over the guide wheel 17 and connects to the winding device. Supported by the guide wheel 17, it moves as follows: Figure 6 As shown, the roller shutter door panel 5, located below the support shaft 13, is always vertically downward and approximately in the middle of the guide groove 4. This ensures that the top sides of the guide groove 4 maintain a certain distance from the roller shutter door panel 5, preventing direct contact between the top of the guide groove 4 and the roller shutter door panel 5, thus avoiding wear between them. Furthermore, multiple guide wheels 17 simultaneously support the roller shutter door panel 5, preventing direct contact between the roller shutter door panel 5 and the guide groove 4, and ensuring even support during winding, preventing uneven force distribution when pulling the roller shutter door panel 5.

[0029] Moreover, such as Figure 5 As shown, the top of each mounting base 18 is connected to the mounting plate 19. At least two adjustment grooves 10 are provided at the support arm 11 corresponding to the mounting base 18. The adjustment grooves 10 are located on the side of the mounting plate 19. Fasteners, which are bolts, are placed in the adjustment grooves 10 at the four corners of the mounting plate 19. After the bolts are placed in the adjustment grooves 10, they are tightened by nuts.

[0030] Since the adjusting groove 10 is horizontally arranged, when the nut is loosened, the supporting shaft 13 can be horizontally advanced towards the guide groove 4 or moved away from the guide groove 4, so as to adjust the position between the guide wheel 17 on the supporting shaft 13 and the guide groove 4, and thus the guide wheel 17 can reach a more suitable position to support the door panel 5 of the rolling shutter door.

[0031] In actual application, as shown in the figure, guide wheels can be installed on both sides of the top of the guide groove 4 or the top of the guide groove 4 can be designed as an arc structure outward, so as to avoid scratching the door panel 5 of the rolling shutter door when the door panel 5 of the rolling shutter door contacts the guide groove 4. Figure 6

[0032] Further, the bottom of the door panel 5 of the rolling shutter door is provided with a reinforcing plate 9, both ends of the reinforcing plate 9 are respectively provided with sliding blocks 16, the sliding blocks 16 are matched with the guide groove 4, the sliding blocks 16 are movably arranged in the guide groove 4, and the reinforcing plate 9 can strengthen the strength and stability of the bottom of the door panel 5 of the rolling shutter door, so that the bottom of the door panel 5 of the rolling shutter door is prevented from being deformed and bent when the door panel 5 of the rolling shutter door is impacted.

[0033] Based on the above embodiment, further optimization can be made, and the application further comprises a protective cover 1, the protective cover 1 covers the two supporting arms 11, the bottom of the protective cover 1 is provided with an opening 20 corresponding to the supporting shaft 13, the protective cover 1 can protect the winding device and avoid foreign matters from entering the door panel 5 of the rolling shutter door during winding, and the door panel 5 of the rolling shutter door enters and exits from the opening 20 during winding, and the edge of the opening 20 of the protective cover 1 is fastened on the wall body through bolts.

[0034] Based on the above embodiment, further optimization can be made, the motor 14 is connected with a controller through wires, and the controller is arranged on a cavity near the guide groove 4, so as to be convenient for an operator to control.

[0035] The above only describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
