Description

Technical Field

[0001] The utility model relates to the technical field of rolling curtain devices, and more specifically to a temperature-insulating rolling curtain device. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. In a fixed slideway, the doors rotate up and down with the reel above the door as the center. Rolling shutter doors are commonly used in shops. Like walls, rolling shutter doors play the role of horizontal partitions. They are composed of curtain plates, seat plates, guide rails, supports, reels, boxes, control boxes, rolling shutter machines, limiters, door lintels, manual quick-release switch devices, push button switches and safety devices. They are usually installed in places where it is inconvenient to use walls for partitions.

[0003] The existing thermal insulation rolling shutter device cannot automatically seal the opening of the guide rail after the rolling shutter door body is fully raised and opened, which makes it easy for foreign matter to enter the inside of the guide rail. When the rolling shutter door body descends again, the foreign matter will hinder the complete closing of the rolling shutter door body, resulting in a large gap between the rolling shutter door body and the ground. The gap will affect the overall thermal insulation effect of the rolling shutter device, and the foreign matter may also be stuck between the rolling shutter door body and the guide rail, causing wear of the rolling shutter door body and the guide rail.

DETAILED DESCRIPTION Example 1

[0022] The existing thermal insulation rolling shutter device cannot automatically seal the opening of the guide rail 3 after the rolling shutter door body 2 is fully raised and opened, which makes it easy for foreign matter to enter the inside of the guide rail 3. When the rolling shutter door body 2 drops again, the foreign matter will hinder the complete closing of the rolling shutter door body 2, resulting in a large gap between the rolling shutter door body 2 and the ground. The formation of the gap will affect the overall thermal insulation effect of the rolling shutter device, and the foreign matter may also be stuck between the rolling shutter door body 2 and the guide rail 3, causing wear of the rolling shutter door body 2 and the guide rail 3. This problem is solved by the following solution.

[0023] See also Figures 1 to 5 , a temperature-insulating rolling shutter device comprises a driving box 1, a rolling shutter door body 2 and a guide rail 3. A rolling shutter machine and a roller are arranged inside the driving box 1. When the rolling shutter machine is started, the roller drives the roller to retract and release the rolling shutter door body 2. The structure is a prior art and will not be described in detail. The bottom of the rolling shutter door body 2 is fixedly connected to a base 4, and a rack 5 is slidably connected to the inside of the guide rail 3. A push plate 6 is fixedly connected to the top of the rack 5. The rolling shutter door body 2 is rolled up until the upper surface of the base 4 is in contact with the lower surface of the push plate 6. When the rolling shutter door body 2 is continued to be rolled up, the base 4 will pull the rack 5 upward through the push plate 6, and the rack 5 drives the support rod 9 to rotate toward the outside of the guide rail 3 through the gear 8, thereby bringing The movable baffle 10 slides out from the inner side of the guide rail 3 to block the guide rail 3 to prevent foreign matter from entering the inner side of the guide rail 3, so as to prevent the rolling door body 2 from being blocked by foreign matter when closing. The rolling door body 2 cannot be closed normally because of the obstruction of foreign matter inside the guide rail 3 and on the corresponding two side edges of the rack 5. A gear 8 is rotatably connected between the two support plates 7. The gear 8 is meshed with the rack 5. A support rod 9 is fixedly connected to the outside of the gear 8. A baffle 10 is rotatably connected to the outside of the support rod 9 away from the gear 8. After the rolling door body 2 is fully opened, the baffle 10 originally stored on the inner side of the guide rail 3 slides out to block the opening of the guide rail 3 to prevent foreign matter from entering.

[0024] A through slot 11 is provided inside the rack 5, and a first spring 12 is fixedly connected to the outside of the baffle 10 on one side close to the rack 5. The first spring 12 passes through the through slot 11 and extends to the other side of the rack 5. The first spring 12 is fixedly connected to the guide rail 3. Through the tension of the first spring 12, when the rolling door body 2 is closed, the first spring 12 will drive the baffle 10 to be retracted to the inner side of the guide rail 3, thereby not affecting the descent of the rolling door body 2.

[0025] The outer wall of the baffle 10 fits with the inner wall of the guide rail 3, and the baffle 10 is slidably connected to the guide rail 3 to limit the position of the baffle 10 and ensure that there is no gap between the baffle 10 and the guide rail 3, thereby preventing foreign matter from entering.

[0026] There are two support rods 9, which are symmetrically distributed. The rack 5, support plate 7, gear 8, support rod 9, through groove 11 and first spring 12 are arranged in two groups and distributed up and down. The two support rods 9 and the baffle 10 form a parallelogram with the guide rail 3, so that when the baffle 10 slides in or out of the guide rail 3, the outer side of the baffle 10 can be in the same plane with the outer side of the guide rail 3 without any depression.

[0027] The width of the through slot 11 is greater than the outer diameter of the first spring 12. When the rolling shutter door body 2 is rolled up, the baffle 10 slides out. During the process, the baffle 10 pulls the first spring 12. The width of the through slot 11 is greater than the outer diameter of the first spring 12, which can prevent the first spring 12 from colliding or getting stuck with the through slot 11.

[0028] The use steps of the utility model are as follows: when the thermal insulation rolling shutter device is in use, the rolling shutter door body 2 is rolled up, and the base 4 pushes against the push plate 6 to drive the rack 5 to move upward, and the rack 5 drives the support rod 9 to rotate in the direction away from the rack 5 through the gear 8 meshing with itself, thereby driving the baffle 10 to slide out of the guide rail 3 and block the guide rail 3. At the same time, the baffle 10 pulls the first spring 12 to prevent foreign objects from entering the guide rail 3 through the baffle 10. When the rolling shutter door body 2 descends, the pulling force of the first spring 12 drives the baffle 10 to automatically retract to the inner side of the guide rail 3. Since the baffle 10 blocks the opening of the guide rail 3, foreign objects cannot enter, thereby avoiding the rolling shutter door body 2 from being unable to fully descend due to foreign objects entering the guide rail 3, resulting in a gap between the base 4 and the ground that affects the thermal insulation effect. Example 2

[0029] The existing rolling shutter device will set a cleaning roller 20 on the outside of the rolling shutter door body 2 to clean it, but the cleaning roller 20 needs to be disassembled and replaced or cleaned after long-term use. The existing rolling shutter device is not convenient for replacing the cleaning roller 20. This problem is solved by the following solution.

[0030] See also Figure 5The difference in the basis of the combined implementation is that a fixed plate 13 is fixedly connected to the outside of the guide rail 3, a rotating rod 14 is rotatably connected to the inside of the fixed plate 13, a rotating plate 15 is fixedly connected to the outside of the rotating rod 14, a fixed rod 16 is fixedly connected to the outside of the guide rail 3 and located above the rotating plate 15, a second spring 17 is fixedly connected between the fixed rod 16 and the rotating plate 15, a mounting groove 18 is provided on the inside of the rotating plate 15 near the guide rail 3, a mounting rod 19 is movably connected to the inside of the mounting groove 18, a cleaning roller 20 is fixedly connected to the outside of the mounting rod 19, the pulling force of the second spring 17 drives the rotating plate 15 to rotate in the direction close to the rolling door body 2, so that the cleaning roller 20 is always pressed against the rolling door body 2, to ensure the cleaning effect of the cleaning roller 20 on the rolling door body 2.

[0031] Usage steps of the utility model: When the thermal insulation rolling shutter device is in use, the rolling shutter door body 2 can be automatically cleaned by the cleaning roller 20 when the rolling shutter door body 2 is rolled up or dropped, and the cleaning roller 20 is installed on the rotating plate 15 through the mounting rod 19 and the mounting groove 18. The user only needs to pull the rotating plate 15 away from the rolling shutter door body 2 to remove the mounting rod 19 from the mounting groove 18 on the rotating plate 15, thereby completing the disassembly of the cleaning roller 20, and facilitating the replacement and cleaning of the cleaning roller 20.
