Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, specifically to a flood-proof roller shutter door. Background Technology

[0002] A roller shutter door is a type of door consisting of multiple movable door panels connected together and limited by fixed tracks. It rotates up and down around a central roller at the top. Common roller shutter doors have a large gap between the door panel and the track, requiring the use of sandbags to prevent flooding.

[0003] According to Chinese Patent Publication No. CN222595903U, "A Flood-Proof Roller Shutter Door," the main feature described is an anti-fall mechanism installed on a vertical track. This anti-fall mechanism includes a stop bar that can move between a stop position and a raised position. After the roller shutter mechanism drives the roller shutter assembly to retract, the stop bar is in the stop position to prevent the roller shutter assembly from passing. Before the roller shutter mechanism drives the roller shutter assembly to extend, the stop bar is in the raised position to allow the roller shutter assembly to pass. Therefore, the flood-proof roller shutter door provided in this application can prevent the roller shutter assembly from falling due to malfunction, further increasing the safety of the flood-proof roller shutter door. It can effectively reduce the risk of the roller shutter assembly falling, reducing the probability of pedestrian injuries, and the anti-fall mechanism is also easy to control.

[0004] Most roller shutters close by manually pulling or using a motor to move the door panels downwards. The panels are then pressed against the track or bottom support surface to seal them and prevent flooding. However, the door panels are connected by shafts, and to reduce wear, gaps are left between them. This allows water to seep in through these gaps, affecting the roller shutter's flood prevention performance. Utility Model Content

[0005] In view of the deficiencies in the prior art, this utility model provides a flood-proof roller shutter door to improve the flood-proof effect of the roller shutter door and reduce the water from penetrating into the other side of the door through the gap between the door panels.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a flood-proof roller shutter door, including a support frame, a reduction motor, a rotating roller, a roller shutter body and a counterweight. L-shaped plates are sleeved on both sides of the roller shutter body. A T-shaped plate is bolted to the side of the L-shaped plate closest to the roller shutter body. A first clamping plate contacts the side of the T-shaped plate closest to the L-shaped plate. The first clamping plate is fixedly connected to one side of the L-shaped plate. A second clamping plate is fixedly connected to one side of the L-shaped plate, and the second clamping plate contacts the T-shaped plate. A connecting sleeve is fixedly connected to one side of the L-shaped plate. A spring rod is inserted into the connecting sleeve. A movable plate is fixedly connected to the end of the spring rod. A first pad made of rubber is glued to the side of the movable plate away from the L-shaped plate. The first pad corresponds to the roller shutter body. A water-blocking plate contacts the side of the roller shutter body closest to the support frame. One side of the water-blocking plate contacts one side of the T-shaped plate.

[0007] As a preferred technical solution of this utility model, a protrusion is fixedly connected to one side of the L-shaped plate. The protrusion contacts the movable plate. By setting the protrusion, it is easy to limit the movable plate and the first pad, thereby promoting the linear movement of the movable plate.

[0008] As a preferred technical solution of this utility model, the T-shaped plate has a first groove on the side away from the first card plate. The first groove has an eight-shaped structure. By setting the first groove, the water baffle can be manually placed to provide a flood prevention effect.

[0009] As a preferred technical solution of this utility model, a second groove is provided at the upper end of the water baffle, and a water blocking strip is fixedly connected to the end of the water baffle away from the second groove. The water blocking strip has an isosceles trapezoidal structure. By providing the second groove and the water blocking strip on the upper and lower sides of the water baffle respectively, the movement path of water during seepage can be increased, thereby improving the waterproof effect.

[0010] As a preferred technical solution of this utility model, the bottom end of the water-blocking strip is glued to a second pad, which is made of rubber. By setting the second pad, the sealing effect can be improved under the gravity of the water-blocking plate.

[0011] As a preferred technical solution of this utility model, a pull ring is fixedly connected to one side of the water baffle away from the roller shutter body. The pull ring is located between the two T-shaped plates, which facilitates manual pulling.

[0012] This utility model has the following advantages: by setting up an L-shaped plate with a split structure and fixing it to a T-shaped plate with bolts, a spring rod causes the moving plate and the first pad to contact the roller shutter body. Then, multiple water baffles are set on the other side and inserted between the L-shaped plate and the T-shaped plate from the first groove, and contact the roller shutter body, thereby providing a barrier to the gaps on the roller shutter body, thereby improving the flood prevention effect and reducing water seepage from the gaps between the door panels.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-4The illustrated flood-resistant roller shutter door includes a support frame 1, a reduction motor, a rotating roller 2, a roller shutter body 3, and a counterweight 4. The roller shutter body 3 is composed of door panels. L-shaped plates 5 are fitted onto both sides of the roller shutter body 3. A T-shaped plate 6 is bolted to the side of the L-shaped plate 5 closest to the roller shutter body 3. A first clamping plate 7 is fixedly connected to the side of the T-shaped plate 6 closest to the L-shaped plate 5. The first clamping plate 7 is fixedly connected to one side of the L-shaped plate 5. Both the first clamping plate 7 and the second clamping plate 8 contact the T-shaped plate 6, increasing the contact area and improving the stability of the connection after the L-shaped plate 5 and T-shaped plate 6 are connected by bolts. A bolt structure is also provided on the contact surface between the first clamping plate 7 and the T-shaped plate 6. A second clamping plate 8 is fixedly connected to one side of the L-shaped plate 5, contacting the T-shaped plate 6. A connecting sleeve 9 is fixedly connected to one side of the L-shaped plate 5, and a spring rod 10 is inserted into the connecting sleeve 9. Pulling the spring rod 10... The spring rod 10 can move the movable plate 11 and remove the bolts to separate the L-shaped plate 5 from the T-shaped plate 6, thereby replacing the first pad 12. The end of the spring rod 10 is fixedly connected to the movable plate 11. The movable plate 11 is glued to the side away from the L-shaped plate 5. The first pad 12 corresponds to the roller shutter body 3. The side of the roller shutter body 3 near the support frame 1 is in contact with the water baffle 13. One side of the water baffle 13 is in contact with the side of the T-shaped plate 6. By setting the water baffles 13 to overlap, when the counterweight 4 is pressed against the ground slot, the water baffle 13 can press the roller shutter body 3 (a rubber plate can be added to the side of the water baffle 13 near the L-shaped plate 5 to adapt to the gap between the door panels and increase the anti-seepage effect), thereby causing one side of the roller shutter body 3 to contact the first pad 12, thereby reducing the water seepage from both sides of the roller shutter body 3 to the side of the roller shutter body 3 near the water baffle 13.

[0020] Among them, a protrusion 14 is fixedly connected to one side of the L-shaped plate 5. The protrusion 14 contacts the moving plate 11. By setting the protrusion 14 in conjunction with the second clamping plate 8, the moving plate 11 can be limited, thereby facilitating the stable movement of the moving plate 11 and the first pad 12.

[0021] The T-shaped plate 6 has a first groove 15 on the side away from the first card plate 7. The first groove 15 has an eight-shaped structure. By setting the first groove 15, the water baffle 13 can be manually placed between the T-shaped plate 6 and the L-shaped plate 5.

[0022] The water baffle 13 has a second groove 16 at its upper end, and a water blocking strip 17 is fixedly connected to the end of the water baffle 13 away from the second groove 16. The water blocking strip 17 has an isosceles trapezoidal structure. By setting the water blocking strip 17 with an isosceles trapezoidal structure, it is easy for the upper water baffle 13 to connect with the lower water baffle 13, and it is easy for the water baffle 13 to be inserted into the first groove 15.

[0023] The bottom end of the water-blocking strip 17 is glued to a second gasket 18, which is made of rubber. By setting the water-blocking strip 17, the sealing effect between the second groove 16 and the water-blocking strip 17 can be increased.

[0024] Among them, a pull ring 19 is fixedly connected to one side of the water baffle 13 away from the roller shutter body 3. The pull ring 19 is located between the two T-shaped plates 6. By setting the pull ring 19, the water baffle 13 can be easily disassembled and installed by manually pulling it.

[0025] Working principle: When the flood season occurs, the bolts can be removed to detach the L-shaped plate 5 from the T-shaped plate 6. The first pad strip 12 is removed and a new first pad strip 12 is installed. Then, the installation is restored. The drive motor rotates, causing the counterweight 4 to move down to the slot inserted into the ground (a slot can be made in the ground corresponding to the counterweight 4 during installation). The roller shutter body 3 unfolds. At this time, the spring rod 10 extends, causing the first pad strip 12 to contact the roller shutter body 3. At the same time, the water baffle 13 is manually inserted into the first groove 15. Then, the multiple water baffles 13 are connected. The water-blocking strip 17 on the bottom side of the upper water baffle 13 corresponds to the second groove 16 on the upper side of the bottom water baffle 13. At this time, the first pad strip 12, the roller shutter body 3, and the water baffle 13 are in contact, which can provide a sealing and water-blocking effect at the gap between the door panels.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
