[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4 A heat-insulating roller shutter door includes a frame 1 and a curtain 2. The top of the curtain 2 is fixed to the top of the frame 1, and a rubber pad 9 is installed at the bottom of the curtain 2. A groove 8 is formed on the inner wall of the bottom of the frame 1, and the rubber pad 9 can be located in the groove 8. Two fixing plates 14 are fixed to the bottom of the frame 1 by bolts. Both fixing plates 14 are threaded with screw rods 11. One end of the screw rod 11 is rotatably connected to a push block 13. Two connecting blocks 12 are fixed to the bottom side of the curtain 2 by bolts, and the inclined surface on the connecting block 12 contacts the inclined surface on the corresponding push block 13. A shielding assembly is provided on one side of the slide 8. The shielding assembly includes a shielding plate 15. When the curtain 2 is closed, the rubber pad 9 at the bottom of the curtain 2 enters the slide 8, and the bottom of the rubber pad 9 contacts the bottom of the slide 8. The rubber pad 9 also contacts the side of the shielding plate 15. The shielding plate 15 is slidably connected in the slide 8. Two first fixing blocks 5 are fixed on one side of the shielding plate 15 by bolts. Rotating the screw 11 causes the push block 13 to move, so that the inclined surface of the push block 13 contacts the inclined surface of the connecting block 12 and presses the inclined surface of the connecting block 12, thereby causing the bottom of the curtain 2 to... The position of the part is restricted and fixed, so that the rubber pad 9 is tightly inserted into the slide groove 8 to achieve further sealing, avoiding a large gap between the bottom of the curtain 2 and the ground, which would result in poor heat preservation of the roller shutter door. Two second fixing blocks 7 are fixed to one side of the frame 1 by bolts. Insertion holes 4 are opened on both the two first fixing blocks 5 and the two second fixing blocks 7. Two connecting holes are opened on the baffle plate 15, and a plug rod 6 is inserted between the connecting hole and the corresponding insertion hole 4 on the second fixing block 7 at the bottom. The top of the plug rod 6 passes through the insertion hole 4 on the first fixing block 5 and is fixed with a magnet by bolts. When the curtain 2 is opened, the rubber pad 9 separates from the slide 8. The worker pulls the magnetic block 3 upward, and the insert rod 6 moves out of the insertion hole 4 and connection hole on the second fixing block 7. Then, the baffle plate 15 is pushed to move inward along the slide 8 until the baffle plate 15 completely covers the slide 8. At this time, the insertion hole 4 on the first fixing block 5 corresponds to the insertion hole 4 on the second fixing block 7. Then, the insert rod 6 moves out of the insertion hole 4 on the first fixing block 5 and the insertion hole 4 on the second fixing block 7, and the magnetic block 3 contacts the upper surface of the first fixing block 5, thereby protecting the slide 8 when it is not in use.

[0024] It should be noted that the magnetic block 3 and the baffle plate 15 are attracted to each other, and the magnetic block 3 can be used to fix the position of the rod 6. The outer side of the lead screw 11 is threaded with a locking nut 10, and the locking nut 10 is in contact with the fixing plate 14. The locking nut 10 can further restrict the position of the lead screw 11 and prevent the lead screw 11 from rotating in the opposite direction and affecting the squeezing effect of the push block 13. The baffle plate 15 can cover the slide groove 8. The bottom of the push block 13 is in contact with the frame 1. The bottom of the outer side of the curtain 2 is fixed with a handle by bolts. The side of the baffle plate 15 can be in contact with the rubber pad 9.

[0025] Working principle: When the curtain 2 is closed, the rubber pad 9 at the bottom of the curtain 2 enters the slide groove 8, and the bottom of the rubber pad 9 contacts the bottom of the slide groove 8, while the rubber pad 9 contacts the side of the baffle plate 15. Then, the screw 11 is rotated, which moves the push block 13, causing the inclined surface of the push block 13 to contact the inclined surface of the connecting block 12 and press against the inclined surface of the connecting block 12. Then, the locking nut 10 is rotated, causing it to press against the fixing plate 14, thereby restricting and fixing the position of the bottom of the curtain 2, and making the rubber pad 9 tightly inserted into the slide groove 8 to achieve further sealing, thus allowing the curtain to be installed with a roller. The curtain door has a better heat preservation effect. When the curtain 2 is opened, the rubber pad 9 separates from the slide 8. The staff pulls the magnetic block 3 upward, and the plug rod 6 moves out of the plug hole 4 and the connection hole on the second fixing block 7. Then push the cover plate 15 to move it inward along the slide 8 until the cover plate 15 completely covers the slide 8. At this time, the plug hole 4 on the first fixing block 5 corresponds to the plug hole 4 on the second fixing block 7. Then the plug rod 6 moves out of the plug hole 4 on the first fixing block 5 and the plug hole 4 on the second fixing block 7, and makes the magnetic block 3 contact the upper surface of the first fixing block 5, so that the slide 8 is protected when not in use.
