Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and in particular to a steel waterproof roller shutter with good bottom sealing effect. Background Technology

[0002] A roller shutter door is a door with multiple articulated door panels linked together, rotating up and down around a central roller within fixed tracks. It consists of multiple parts, including curtain panels, base plate, guide rails, supports, roller, housing, control box, roller motor, limit switch, lintel, manual quick-release switch, push-button switch, and safety devices. It is generally installed in locations where walls are inconvenient to use for partitions. Most roller shutter doors are made of steel, and when fully lowered, gaps of varying sizes remain between the door and the ground. In rainy weather or other special circumstances, water can easily enter, hindering moisture control in the room. Therefore, we propose a waterproof steel roller shutter with a good bottom sealing effect.

[0003] An existing patent (publication number: CN221322240U) discloses a steel waterproof roller shutter with good bottom sealing effect, including a roller shutter body and a sealing mechanism. The sealing mechanism includes a sealing base pad body and two sealing base pad side bodies, all located at the bottom end face of the roller shutter body. This sealing mechanism allows the relatively soft sealing base pad body to replace the roller shutter body in contact with the ground, thereby filling the gap between the roller shutter body and the ground and preventing liquid from entering. Simultaneously, the sealing base pad body, sealing base pad side bodies, and roller shutter body all have a relatively tight and easy-to-disassemble structure, facilitating replacement or maintenance after component aging. However, in implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved: The above device seals the ground through the sealing base pad, but after the sealing base pad comes into contact with water and dries, thermal expansion and contraction cause the sealing base pad to easily deform, resulting in poor water protection effectiveness. Utility Model Content

[0004] To address the issue mentioned above where sealing the ground with a sealing pad results in deformation due to thermal expansion and contraction after the water dries, leading to poor water protection, this invention provides a steel waterproof roller shutter with a good bottom sealing effect.

[0005] This utility model provides a steel waterproof roller shutter with good bottom sealing effect, using the following technical solution:

[0006] A steel waterproof roller shutter with good bottom sealing effect includes a storage frame, in which a roller shutter body is fixedly installed, and a sealing gasket is fixedly installed on the lower side of the roller shutter body.

[0007] The outer side of the sealing gasket is movably fitted with a fixed frame, and the top left and right sides and the front and back sides of the fixed frame are provided with movable grooves, and a sealing element is slidably arranged inside the movable groove.

[0008] The above technical solution facilitates quick sealing of the roller shutter body and the fixed frame, provides good waterproofing at the bottom of the roller shutter body, and allows for quick removal and replacement of the sealing gasket, except for the removal of the silicone strip from the roller shutter body.

[0009] Optionally, in the above-mentioned steel waterproof roller shutter with good bottom sealing effect, the lower side of the sealing gasket is rounded, and the sealing gasket is a hard rubber strip. Four internal hex bolts are rotatably provided on the front side of the sealing gasket, and the rear end of the internal hex bolts extends to the rear side of the roller shutter body and extends to the rear side of the sealing gasket.

[0010] The above technical solution facilitates the connection and fixation of the sealing gasket and the roller shutter body using hexagonal bolts.

[0011] Optionally, in the above-mentioned steel waterproof roller shutter with good bottom sealing effect, the sealing element includes movable strips, the number of movable strips is four, the four movable strips are respectively slidably disposed inside the four movable grooves, and C-shaped sealing strips are fixedly disposed on the opposite side of the four movable strips in pairs.

[0012] The above technical solution facilitates the use of C-shaped sealing strips to enhance the sealing effect at the bottom of the roller shutter door body.

[0013] Optionally, in the above-mentioned steel waterproof roller shutter with good bottom sealing effect, the shape of the moving strip and the shape of the inside of the moving groove are both T-shaped, and a compression spring is fixedly provided on the side of the moving strip, with one end of the compression spring fixedly connected to the side of the moving groove.

[0014] The above technical solution facilitates the T-shaped moving strip to slide vertically and stably inside the moving groove.

[0015] Optionally, in the above-mentioned steel waterproof roller shutter with good bottom sealing effect, there are two C-shaped sealing strips, and the two vertical strips of the front C-shaped sealing strip are fixedly provided with inserts on the sides, and the two vertical strips of the rear C-shaped sealing strip are provided with slots on the sides, and the slots cooperate with the inserts.

[0016] The above technical solution facilitates the use of slots and inserts to enhance the sealing effect between the vertical strips of the two C-shaped sealing strips.

[0017] Optionally, in the above-mentioned steel waterproof roller shutter with good bottom sealing effect, the upper side of the horizontal bar of the C-shaped sealing strip is provided with a 20° bevel angle, and silicone strips are fixedly provided on the opposite side of the two horizontal bars of the two C-shaped sealing strips.

[0018] The above technical solution facilitates the drainage of water from the upper side of the horizontal bar of the C-shaped sealing strip with a sloping top, and the silicone strip can contact the inside of the groove, so that the roller shutter door body is sealed with the fixed frame.

[0019] Optionally, in the above-mentioned steel waterproof roller shutter with good bottom sealing effect, several grooves are provided on both the front and rear sides of the roller shutter body, and the interior of two of the grooves respectively contacts the side of the silicone strip.

[0020] The above technical solution improves the sealing between the roller shutter body and the fixed frame when the two grooves on the lower side come into contact with the inside of the silicone strip.

[0021] In summary, this utility model has at least one of the following beneficial effects:

[0022] By applying waterproof sealant to the bottom of the fixed frame and fixing the fixed frame, the rolling shutter door body moves the sealing pad down into the fixed frame, so that the two C-shaped sealing strips are limited by the compression spring, and the two silicone strips are put together. At the same time, the two inserts move into the slots, which can quickly seal the rolling shutter door body and the fixed frame, and has a good waterproof effect on the bottom of the rolling shutter door body.

[0023] The sealing gasket moves down into the fixed frame by the roller shutter body. When the sealing gasket moves, its side presses against the C-shaped sealing strip, causing the two C-shaped sealing strips to open to the front and back sides. Then, the C-shaped sealing strips are reset by the compression spring, sealing the roller shutter body and the fixed frame. By moving the two C-shaped sealing strips to the front and back sides, the upper side of the inner wall of the fixed frame can be opened, releasing the silicone strip from the roller shutter body and allowing for quick removal and replacement of the sealing gasket.

[0029] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a steel waterproof roller shutter with good bottom sealing effect, including a storage frame 1, a roller shutter body 2 is fixedly installed inside the storage frame 1, and a sealing gasket 3 is fixedly installed on the lower side of the roller shutter body 2.

[0031] A fixed frame 6 is movably sleeved on the outer side of the sealing gasket 3. Movable grooves 4 are provided on the front and back sides of the top left and right sides of the fixed frame 6. A sealing element 5 is slidably arranged inside the movable groove 4.

[0032] Working principle: When using this steel waterproof roller shutter with good bottom sealing effect, first apply waterproof sealant to the bottom of the fixed frame 6 and fix the fixed frame 6. When sealing the roller shutter body 2, pull the roller shutter body 2 downward to move the sealing pad 3 downward into the inside of the fixed frame 6, and limit the two C-shaped sealing strips 502 through the compression spring 506, so that the two silicone strips 505 stick together. At the same time, the two inserts 503 move into the inside of the slot 504, which can quickly seal the roller shutter body 2 and the fixed frame 6, and the waterproof effect on the bottom of the roller shutter body 2 is good.

[0033] The sealing gasket 3 moves downward into the fixed frame 6 via the roller shutter body 2. When the sealing gasket 3 moves, its side presses against the C-shaped sealing strip 502, causing the two C-shaped sealing strips 502 to open to the front and rear sides respectively. After the sealing gasket 3 moves into the fixed frame 6, the C-shaped sealing strips 502 are reset by the rebound force of the compression spring 506, sealing the roller shutter body 2 and the fixed frame 6. By moving the two C-shaped sealing strips 502 to the front and rear sides, the upper side of the inner wall of the fixed frame 6 can be opened, releasing the silicone strip 505 from the roller shutter body 2, and thus quickly disassembling and replacing the sealing gasket 3.

[0034] It should be noted that the lower side of the sealing gasket 3 is rounded, and the sealing gasket 3 is a hard rubber strip. The front side of the sealing gasket 3 is rotatably equipped with four hexagonal bolts 301. The rear end of the hexagonal bolts 301 extends to the rear side of the roller shutter body 2 and extends to the rear side of the sealing gasket 3.

[0035] Using the above technical solution, the sealing gasket 3 and the roller shutter body 2 can be easily connected and fixed by the internal hex bolt 301.

[0036] It should be noted that the sealing element 5 includes four movable strips 501. The four movable strips 501 are slidably disposed inside the four movable grooves 4. Each of the four movable strips 501 is fixedly provided with a C-shaped sealing strip 502 on one side of each pair of opposite sides.

[0037] By adopting the above technical solution, the sealing effect at the bottom of the roller shutter body 2 can be increased by the C-shaped sealing strip 502.

[0038] It should be noted that the shape of the moving bar 501 and the shape of the inside of the moving groove 4 are both T-shaped, and a compression spring 506 is fixedly provided on the side of the moving bar 501, with one end of the compression spring 506 fixedly connected to the side of the moving groove 4.

[0039] Using the above technical solution, the T-shaped moving bar 501 can slide vertically and stably inside the moving groove 4.

[0040] It should be noted that there are two C-shaped sealing strips 502, and the two vertical strips of the front C-shaped sealing strip 502 are fixedly provided with inserts 503 on their sides, and the two vertical strips of the rear C-shaped sealing strip 502 are provided with slots 504 on their sides, and the slots 504 cooperate with the inserts 503.

[0041] By adopting the above technical solution, the sealing effect between the vertical strips of the two C-shaped sealing strips 502 can be increased by the cooperation of the slot 504 and the insert block 503.

[0042] It should be noted that the upper side of the horizontal bar of the C-shaped sealing strip 502 is provided with a 20° bevel angle, and a silicone strip 505 is fixedly installed on the opposite side of the two horizontal bars of the two C-shaped sealing strips 502.

[0043] Using the above technical solution, the horizontal bar of the C-shaped sealing strip 502 with a sloping top facilitates the drainage of water on its upper side, and the silicone strip 505 can contact the inside of the groove 201, so that the roller shutter body 2 and the fixed frame 6 are sealed.

[0044] It should be noted that several grooves 201 are provided on both the front and rear sides of the roller shutter door body 2, and the interior of two of the grooves 201 respectively contacts the side of the silicone strip 505.

[0045] By adopting the above technical solution, the sealing between the roller shutter body 2 and the fixed frame 6 can be increased when the two grooves 201 on the lower side come into contact with the inside of the silicone strip 505.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
