Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, specifically to a turbine-insulated roller shutter with double sealing edges. Background Technology

[0002] In modern society, roller shutters have been widely used in commercial, industrial, and residential buildings due to their unique advantages. With continuous technological advancements, the functions of roller shutters are constantly expanding, with various types emerging such as fire-resistant roller shutters, burglarproof roller shutters, and insulated roller shutters to meet the specific needs of different scenarios. With the rapid development of industries such as cold chain logistics, food processing, and precision manufacturing, the requirements for the sealing and insulation properties of roller shutters have reached unprecedented levels.

[0003] When traditional roller shutters are closed, there are often obvious gaps between the door and the frame. These gaps become channels for cold or hot air to escape, thus consuming a lot of electricity.

[0004] Therefore, we propose a turbine-insulated roller shutter door with double sealing edges. Utility Model Content

[0005] The main purpose of this utility model is to provide a turbine-insulated roller shutter door with double sealing edges. By setting a first sealing strip at the bottom of the bottom beam and a sealing system consisting of fasteners, positioning parts and a second sealing strip on the side of the guide rail, a double effective seal is formed at the bottom and the side, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A turbine-style insulated roller shutter door with double sealing edges includes a first guide rail, a second guide rail, roller shutter slats, a bottom beam, and a cover. The first and second guide rails are arranged parallel to each other, and the top ends of the first and second guide rails are connected to the bottom end of the cover. An installation channel for installing the roller shutter slats is provided between the first and second guide rails. Multiple roller shutter slats are arranged parallel to each other, and the multiple roller shutter slats are connected sequentially to form the roller shutter door body. The top end of the bottom beam is fixedly connected to the roller shutter slats at the bottom end of the roller shutter door body, and a first sealing strip is fixedly glued to the bottom end of the bottom beam. Both the first guide rail and the second guide rail have an installation cavity for assembling the roller shutter slat at one end near the installation channel. Both the first guide rail and the second guide rail have a fastening groove on one side for installing fasteners. Two sets of fasteners are arranged in parallel. The end of the fastener near the roller shutter slat is located in the installation cavity. The fastener has an L-shaped structure. A second sealing strip and a positioning element for limiting the end position are respectively installed on the end of the fastener located in the installation cavity.

[0007] By adopting the above technical solutions and using the above sealing structures in combination, the gaps in the roller shutter door when it is closed are greatly reduced, the overall airtightness is significantly improved, and the exchange of hot and cold air between indoors and outdoors is effectively prevented. The heat preservation effect is outstanding, and it is especially suitable for places with strict temperature control requirements, such as cold chain logistics and food processing workshops, which helps to significantly reduce energy consumption.

[0008] Specifically, one side of the positioning component is embedded in the inner wall of one end of the fastener, and a positioning groove is provided between the positioning component and the fastener to match the side of the first guide rail and the second guide rail.

[0009] Specifically, the end of the fastener away from the positioning member is embedded in the fastener groove, and the fastener is fixedly connected to one side of the first guide rail and the second guide rail by the first bolt.

[0010] Specifically, the positioning member has a groove for installing a second sealing strip at the end away from the positioning groove, and the second sealing strip is located between the roller shutter slat and the fastener.

[0011] Specifically, both ends of the roller shutter slat are provided with mounting grooves for installing end heads, which are snapped into the two ends of the roller shutter slat, and the end heads are fixedly connected to the two ends of the roller shutter slat by a second bolt.

[0012] Specifically, both the first and second guide rails have a limiting groove on the lower part of the side near the installation channel to limit the position of the bottom beam, and the limiting groove is connected to the installation cavity.

[0013] The beneficial effects of this utility model are as follows: The turbine-style insulated roller shutter door with double sealing edges described in this utility model forms a double effective seal on the bottom and sides through a first sealing strip set at the bottom of the bottom beam and a sealing system composed of fasteners, positioning parts, and a second sealing strip set on the side of the guide rail. The combined use of the above sealing structures greatly reduces gaps in the closed state of the roller shutter door, significantly improving the overall airtightness, thereby effectively preventing the exchange of hot and cold air between indoors and outdoors. The insulation effect is outstanding, making it particularly suitable for places with strict temperature control requirements, such as cold chain logistics. In applications such as food processing workshops, this design helps significantly reduce energy consumption. The L-shaped fasteners, combined with the grooves on the guide rail and secured with bolts, ensure a secure and reliable installation of the entire side sealing assembly, facilitating easy disassembly and maintenance. The positioning grooves formed by the positioning components and fasteners, along with their engagement with the end caps, ensure smooth operation of the roller shutter, reducing shaking and noise. The limiting groove design at the bottom of the guide rail ensures the accuracy of the bottom beam's closing position, allowing for uniform compression of the bottom first sealing strip and preventing sealing issues caused by bottom beam misalignment, further guaranteeing the bottom sealing effect.

The first guide rail 1 and the second guide rail 2 are arranged in parallel relative to each other, and the top ends of the first guide rail 1 and the second guide rail 2 are connected to the bottom end of the cover 17. An installation channel 3 for installing the roller shutter 4 is provided between the first guide rail 1 and the second guide rail 2. Multiple roller shutter 4s are arranged in parallel relative to each other, and the multiple roller shutter 4s are connected in sequence to form the roller shutter door body. The top end of the bottom beam 8 is fixedly connected to the roller shutter 4 at the bottom end of the roller shutter door body, and a first sealing strip 9 is fixedly glued to the bottom end of the bottom beam 8. The first guide rail 1 and the second guide rail 2 are each provided with an installation cavity 10 for assembling the roller shutter slat 4 at one end near the installation channel 3. The first guide rail 1 and the second guide rail 2 are each provided with a fastening groove 5 for installing fasteners 6 on one side. Two sets of fasteners 6 are arranged in parallel.

The end of the fastener 6 located in the installation cavity 10 is respectively equipped with a second sealing strip 15 and a positioning element 14 for limiting the position of the end 12.

[0018] When in use, when the roller shutter door is closed, the roller shutter 4 retracts and drives the end 12 into position, the end 12 will tightly press the second sealing strip 15; the fastener 6 itself also constitutes part of the sealing system; in this way, on both sides of the roller shutter door, a second side sealing barrier is formed by the fastener 6, the positioning element 14 and the second sealing strip 15. On the lower part of the first guide rail 1 and the second guide rail 2 near the installation channel 3, there is a limiting groove 13. The limiting groove 13 is connected to the installation cavity 10. When the roller shutter door is completely closed, the two ends of the bottom beam 8 are just embedded in the limiting groove 13, which restricts the position of the bottom beam 8 and ensures the centering of the door.

[0019] The present invention also includes that one side of the positioning member 14 is embedded in the inner wall of one end of the fastener 6, and a positioning groove 16 adapted to the side of the first guide rail 1 and the second guide rail 2 is provided between the positioning member 14 and the fastener 6.
