DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Embodiment: please refer to Figures 1 to 6 According to the embodiment of the utility model, an electric roller shutter door convenient for maintaining and replacing curtain pieces is provided, which comprises a cover 1, a guide rail 2 and a curtain piece 3 assembly. A winding shaft (not shown) driven by a motor is arranged in the cover 1. Two guide rails 2 are arranged at the bottom of the cover 1 on both sides. One end of the curtain piece 3 assembly is fixedly connected with the winding shaft in the cover 1, and the other end slides along the guide rail 2. The curtain piece 3 assembly comprises a plurality of curtain pieces 3. The curtain pieces 3 are made of inorganic fireproof fiber material. Adjacent curtain pieces 3 are detachably connected through connecting pieces 4. The two ends of the connecting piece 4 are provided with sliding blocks 19 which are in sliding cooperation with the two guide rails 2 respectively.

[0026] The electric roller shutter door with the above structure is convenient to maintain and replace the curtain piece. The curtain piece 3 assembly is connected by a plurality of curtain pieces 3, and the adjacent curtain pieces 3 are detachably connected by the connecting piece 4. When part of the curtain piece 3 is damaged, the part of the curtain piece 3 can be detached and replaced with a new curtain piece 3. Compared with the whole curtain piece 3 assembly, the electric roller shutter door with the above structure is convenient to replace the damaged part without replacing the whole curtain piece 3 assembly, which reduces the maintenance cost and improves the efficiency of maintenance and replacement.

[0027] In the example embodiment, the connecting piece 4 is provided with a connecting groove 5 at the position connected with the curtain piece 3. Two clamping plates 7 are rotatably connected in the connecting groove 5 by a connecting rod 6, and the two clamping plates 7 are elastically clamped on both sides of the curtain piece 3. Specifically, one end of the connecting rod 6 is rotatably connected with the connecting piece 4 by a first rotating shaft 8, and the other end of the connecting rod 6 is rotatably connected with the clamping plate 7 by a second rotating shaft 9. After the curtain piece 3 is placed in the connecting groove 5, the two clamping plates 7 can be elastically clamped on both sides of the curtain piece 3, so as to fix the curtain piece 3 in the connecting groove 5. When the curtain piece 3 is pulled by an external force, the two clamping plates 7 can exert a pressure on the curtain piece 3 in the thickness direction of the curtain piece 3 under the action of the connecting rod 6, so as to achieve the effect of clamping tighter and tighter. In this way, the firmness of the connection between the curtain piece 3 and the connecting piece 4 can be improved. When the curtain piece 3 is detached, only a force away from the curtain piece 3 needs to be applied to the two elastic plates, so that the curtain piece 3 can be taken out of the connecting groove 5.

[0028] In order to improve the stability of the clamping block during movement, in the example embodiment, the two ends of the clamping plate 7 are rotatably connected with the connecting piece 4 by two mutually parallel connecting rods 6. After the above structure is set, the clamping plate 7 will always be parallel to the curtain piece 3 during movement, which facilitates the clamping plate 7 to exert a clamping force on the curtain piece 3 or release the clamping of the curtain piece 3.

[0029] In the example embodiment, the second rotating shaft 9 of the two clamping plates 7 is connected by a sliding plate 10. The sliding plate 10 is provided with a long strip-shaped sliding hole 11, and the end of the second rotating shaft 9 away from the clamping plate 7 is slidably connected to the sliding hole 11. The sliding plate 10 is fixedly connected with a sliding rod 12, and the end surface of the connecting piece 4 is fixedly provided with a connecting piece 13 slidably inserted with the sliding rod 12. A spring 14 is sleeved on the sliding rod 12 between the connecting piece 13 and the sliding plate 10. After the above structure is set, the two clamping plates 7 are elastically connected with the connecting piece 4 through the cooperation of the sliding plate 10, the second rotating shaft 9, the sliding rod 12, the connecting piece 13 and the spring 14. When it is necessary to release the clamping of the curtain piece 3 by the two clamping plates 7, the sliding plate 10 can be pushed to move towards the connecting piece 13. At this time, the sliding rod 12 slides on the connecting piece 13, the spring 14 is compressed, and the two clamping plates 7 move away from each other to release the clamping of the curtain piece 3. In this way, the disassembly of the curtain piece 3 becomes more simple and efficient.

[0030] In the example embodiment, the two clamping plates 7 are provided with inclined surfaces 15 on the side facing the opening of the connecting groove 5. By providing the inclined surfaces 15 on the clamping plates 7, the gap between the two clamping plates 7 is V-shaped on the side facing the opening of the connecting groove 5, so that the curtain panel 3 is more easily inserted into the gap between the two clamping plates 7 from the side facing the opening of the connecting groove 5, facilitating the installation of the curtain panel 3.

[0031] In the example embodiment, the end surface of the connecting piece 4 is fixedly connected with a connecting base 16 through a screw 17, the connecting base 16 is provided with two protruding portions 18 on the side spaced from the connecting piece 4, and the other side of the connecting base 16 is provided with a sliding block 19 slidingly matched with the guide rail 2. After being thus arranged, when the connecting base 16 is connected to the end surface of the connecting piece 4, the structures such as the connecting rod 6 and the clamping plate 7 can be shielded, so as to reduce the possibility of damage of these structures during the movement of the curtain panel 3. In addition, the two protruding portions 18 of the connecting base 16 can be gaps with openings around the connecting base 16 and the end surface of the connecting piece 4, through which the sliding plate 10 can be conveniently controlled by the user, thereby facilitating the disassembly and assembly of the curtain panel 3.

[0032] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
