Benefits of technology

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the door body is composed of multiple door panels, and adjacent door panels are assembled by hanging plates and hanging rods. However, the hanging plates and hanging rods need to be assembled and disassembled at a certain angle. However, when the roller shutter door is rolled up, the rolling angle makes it difficult for adjacent door panels to separate. Second, adjacent door panels are connected by a pin on the mating plate inserted into a pin hole, which improves the assembly firmness between adjacent door panels. Third, the top plate is rotated by a rotating rod and inserted into the pin hole, which lifts the top plate against the pin. At this time, most of the pin extends outside the mating plate, and the top plate does not contact the pin. The pin is then released by the contraction of the tension spring, which releases the relationship between the pin and the pin hole, thus facilitating the replacement of some door panels later.

[0025] Example 1

[0026] Please see Figure 1-6An embodiment of this utility model provides: a splicing fireproof roller shutter door, comprising: a storage box 1, one end of which is provided with an installation plate 8, the installation plate 8 having a through hole 7, the storage box 1 being installed on the door frame through the through hole 7 with the aid of screws; a door frame 2, the door frame 2 being provided on one side of the door frame, and a door frame 3 being provided on the side of the door frame away from the door frame 2; a door body 4 being provided inside the storage box 1, and the door body 4 extending to the outside of the storage box 1; the door body 4 including a door panel 41, a hanging plate 10 being provided at the middle of the top of the door panel 41, and a hanging rod 11 being provided below the door body 4 at the position corresponding to the hanging plate 10 and being hooked to the hanging plate 10. When assembling adjacent door panels 41, the lower door panel 41 is tilted, at which point the hanging plate 10 and hanging rod 11 are hooked together. After hooking, the door panel 41 is in a vertical state, thus completing the assembly of adjacent door panels 41. The angle between adjacent door panels 41 needs to be properly controlled before they can be disassembled. Fire-retardant materials are applied to the surfaces of the storage box 1, door frame 2, door frame 3, and door body 4. Handles 9 are fixed to both sides of one of the door panels 41. Holding the handles 9 will push or pull the door body 4. The fire-retardant materials on the surfaces of the storage box 1, door frame 2, door frame 3, and door body 4 provide a degree of fire protection.

[0027] Example 2

[0028] Please see Figure 1-6 A type of fireproof rolling shutter door with interlocking panels has recessed grooves 5 located near the top of door frame 2 and door frame 3, with the height of the grooves 5 being greater than the height of the door panel 41. Through holes 6 are horizontally spaced at equal intervals inside door frame 2 and door frame 3, and door frame 2 are fixed to the building via expansion screws through the through holes 6. A mating plate 13 is located on the upper surface of the door panel 41 near the top, with an inner cavity 20 within the mating plate 13. Pins 14 are inserted into both ends of the mating plate 13, and pin holes 12 are located on both sides of the door panel 41 below the mating plate 13, corresponding to the positions of the mating plates 13, for inserting the pins 14. A vertical plate 15 is located within the inner cavity 20, and a tension spring 16 is located between the vertical plate 15 and the pins 14, the tension spring 16 being in a retracted state. A rotating rod 17 is located on the surface of the door 4 and inside the inner cavity 20, with one end of the rotating rod 17 extending to the outside of the door panel 41. When the rotating rod 17 rotates, it releases the relationship between the top plate 18 and the latch rod 14. At this time, the latch rod 14 retracts into the interior of the mating plate 13 under the tension of the vertical plate 15, thus releasing the relationship between the two ends of the adjacent door panels 41. Then, one of the latch rods 14 is tilted to a certain extent to separate the relationship between the adjacent door panels 41, which facilitates the replacement of the damaged door panel 41.

[0029] A top plate 18 is provided on the surface of the rotating rod 17 inside the inner cavity 20, and the top plate 18 is arc-shaped at the position away from the rotating rod 17. A right-angle notch is opened on the surface of the pin rod 14, and the right-angle notch corresponds to the position of the top plate 18. After the upper and lower door panels 41 are assembled, the rotating rod 17 is rotated so that the top plate 18 is inserted into the insertion hole 19 at one end of the pin rod 14. At this time, the tension spring 16 is in the fully extended state, and one end of the pin rod 14 extends outward relative to the connecting plate 13. The pin rod 14 is inserted into the pin hole 12, fixing the adjacent door panels 41 together and making them less likely to detach later.

[0030] Working principle: When in use, the storage box 1 is first assembled onto the building through the expansion screw through the through hole 7. Similarly, the door frame 2 and the door frame 3 are assembled onto the building through the expansion screw through the through hole 6. When in use, the door 4 is rolled up by the existing motor drive, chain drive, limit switch control and control system in the storage box 1. The two sides of the door 4 are located inside the door frame 2 and the door frame 3.

[0031] Secondly, when the door panel 41 on part of the door body 4 is damaged, it can be controlled in a position parallel to the concave groove 5. At this time, rotate the rotating rod 17, and the top plate 18 will disengage from the pin rod 14. Then, under the action of the tension spring 16, the pin rod 14 will release the relationship between the pin rod 14 and the pin hole 12. After rotating the door panel 41 to a suitable angle, push to release the relationship between the hanging plate 10 and the hanging rod 11. This makes it easy to replace the door panel 41 in part, and finally complete the use of the spliced ​​fireproof roller shutter door.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
