Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof roller shutter technology, and in particular to a waterproof structure at the bottom of a roller shutter and a roller shutter device. Background Technology
[0002] In rainy areas, the bottom of roller shutters at factory installation openings is crucial. Because these openings are used for loading and unloading goods, the bottom of the shutter generally needs to be flat. The recessed bottom groove of the shutter often accumulates water during rain, and combined with wind pressure, this water can flow back into the building. Existing waterproofing structures at the bottom of roller shutters typically use simple edge sealing or foot pedals, which have drawbacks such as insufficient waterproofing performance, short lifespan, and easy aging of waterproofing materials. On the one hand, simple edge sealing is prone to peeling or deformation due to repeated movement of the shutter, leading to leaks. On the other hand, while foot pedals can effectively isolate ground moisture, they cannot completely prevent rainwater and accumulated water from seeping into the interior of the shutter from the bottom, causing dampness inside and affecting the user experience. Utility Model Content

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0036] Example 1
[0037] Please refer to Figure 1 and Figure 2 A waterproof structure for a roller shutter section, which cooperates with a roller shutter door 100, includes: a ground groove 200, which is disposed on the ground structure directly below the roller shutter door 100;
[0038] A steel channel structural component 300 is installed in the ground trench 200, and an opening 310 is provided on the side facing the roller shutter door 100. The roller shutter door 100 is adapted to the opening 310. The steel channel structural component 300 extends out of the ground trench 200 and has a drain hole 320 on the side wall facing the outside.
[0039] The inclined surface structural component 400 is installed in the steel channel structural component 300, and the downward inclined direction of the inclined surface of the inclined surface structural component 400 faces the drain hole 320.
[0040] Through the above structural design, the trench 200 is used to embed the steel trough structural member 300. The height of the trench wall facing outdoors is lower than the height of the trench wall facing indoors, forming a height difference. The trench wall facing outdoors of the steel trough structural member 300 is higher than the trench wall facing outdoors of the trench 200. The drain hole 320 is set on the trench wall facing outdoors of the steel trough structural member 300. The inclined structural member 400 is embedded in the steel trough structural member 300. Since the inclined surface of the inclined structural member 400 faces outdoors, when the wind pressure is high during rainy days, the trench 200 can be used to reduce the water pressure. 00. The steel channel structure 300 and the inclined structure 400 can effectively block the overflowing water through the steel channel structure 300. The inclined structure 400 is embedded in the bottom of the steel channel structure 300. The inclined structure 400 is higher inside and lower outside, which can guide the water to the drain hole 320 and discharge the water out of the steel channel structure 300. This design is low cost and simple in structure, which helps to prevent rainwater backflow. The roller shutter door 100 is inserted into the steel channel structure 300 through the opening 310, but does not come into contact with the inclined structure 400.
[0041] Specifically, waterproof sealant 500 is provided between the side wall of the steel channel structural component 300 and the ground channel 200.
[0042] Through the above structural design, the steel channel structural component 300 is sealed with waterproof sealant 500 between it and the ground decorative surface on both sides, which plays a role in preventing water seepage.
[0043] Specifically, in a side view, the drain hole 320 is located above the inclined structural member 400.
[0044] With the above structural design, the drain hole 320 is located slightly above the inclined structural member 400, which is conducive to the outflow of rainwater.
[0045] Example 2
[0046] The waterproof structure of the roller shutter provided in Example 1 is further optimized, specifically, as follows: Figure 1 and Figure 2 As shown, the cross-sectional width of opening 310 is greater than or equal to the width of the bottom surface of roller shutter door 100.
[0047] Through the above structural design, in this embodiment, the cross-sectional width of the opening 310 is slightly larger than the width of the bottom surface of the roller shutter door 100, which is conducive to the insertion of the roller shutter door 100 and at the same time prevents rainwater from seeping downward.
[0048] Example 3
[0049] The waterproof structure of the roller shutter provided in Embodiment 1 or 2 is further optimized, such as... Figure 1 and Figure 2 As shown, a groove 600 is provided on the side wall of the roller shutter door 100 facing the interior, and the groove 600 is connected to the top of the steel channel structure 300.
[0050] Through the above structural design, a groove 600 is provided at the bottom of the roller shutter door 100 facing the interior side wall. The groove 600 is engaged with the steel channel structural member 300, which helps to further fix the roller shutter door 100 and prevent the roller shutter door 100 from shaking even in stormy weather.
[0051] Specifically, a water-blocking structure 700 is installed on the top surface of the steel channel structure 300 on one side of the interior.
[0052] Through the above structural design, the water-blocking structural component 700 is a metal component with several small holes. While providing ventilation, it can limit the seepage caused by rainwater impact, which helps prevent rainwater from flowing back into the room.
[0053] Specifically, the inclined structural component 400 is a rubber strip.
[0054] Through the above structural design, in this embodiment, the inclined structural component 400 is a rubber strip. Under different requirements, other materials can also be considered according to the ambient temperature.
[0055] Specifically, it also includes an elastic seal, which is disposed in the groove 600 and abuts against the top of the steel channel structure 300.
[0056] Specifically, the steel channel structural component 300 and the water-blocking structural component 700 are integrally formed.
[0057] This utility model also provides a roller shutter device, including the waterproof structure of the roller shutter part described above, which is located directly below the roller shutter door 100 and cooperates with the roller shutter door 100.
[0058] The waterproof structure at the bottom of the roller blind and the roller blind device provided by this utility model are used as follows:
[0059] When the wind pressure is high during rainy days, by setting up the ground trench 200, the steel trough structure 300 and the inclined structure 400, the overflowing water can be effectively blocked by the steel trough structure 300. The inclined structure 400 is embedded in the bottom of the steel trough structure 300. The inclined structure 400 is higher on the inside and lower on the outside, which can guide the water to the drain hole 320 and discharge the water out of the steel trough structure 300. This design is low in cost and simple in structure, which helps to prevent rainwater backflow.
