Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy roller shutter technology, specifically to an aluminum alloy roller shutter with high impact resistance. Background Technology

[0002] A roller shutter door is a door with multiple articulated door panels linked together. It moves up and down within a fixed track, rotating around a central roller at the top. Roller shutter doors are commonly used in shops. Like walls, roller shutter doors serve as horizontal partitions. They consist of multiple parts, including curtain panels, base plates, guide rails, supports, rollers, housing, control box, roller door motor, limit switches, lintel, manual quick-release switch, push-button switch, and safety devices. They are generally installed in locations where walls are inconvenient to use for partitioning.

[0003] According to a search, Chinese patent document, publication number CN213683864U, discloses a multi-layer aluminum alloy roller shutter door. This door utilizes a composite aluminum alloy, with double layers offering better strength and sound insulation. The reinforcing ribs further enhance the overall impact resistance of the roller shutter. However, while the reinforcing ribs improve the overall strength, gaps between them result in poor impact resistance in the middle section. When concentrated external force impacts areas without reinforcing ribs, these areas are easily damaged, leading to a shorter lifespan. Furthermore, when the roller shutter is pulled down and locked, the lower end of the shutter impacts the lock, potentially damaging both the lock and the lower part of the shutter, or causing deformation that affects its usability.

It has high efficiency in impact resistance, is durable and sturdy as a whole, and has a cushioning effect, which improves the service life of the roller shutter door and avoids damage to the door body and lock, thus solving the above-mentioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-impact-resistant aluminum alloy roller shutter door, comprising a door frame, a winding box provided on the top side of the door frame, a roller shutter door body movably installed on the inner side of the door frame, the roller shutter door body comprising an aluminum alloy surface layer and reinforcing composite ribs, reinforcing composite ribs provided on the inner side of the aluminum alloy surface layer, a fixing plate fixedly installed at the lower end of the aluminum alloy surface layer, a slider provided on the right side of the fixing plate, and a positioning rod fixedly installed on the bottom side of the slider.

[0008] Preferably, a winding motor is provided on the right side of the winding box, a winding shaft is fixedly installed on the left end of the winding motor, and sliding grooves are respectively opened on opposite sides of the door frame. A positioning hole is opened on the bottom side of the inner side of the sliding groove, and a rubber seat is fixedly installed on the bottom side of the inner side of the positioning hole.

[0009] The above technical solution facilitates the winding of the roller shutter door body by driving the winding shaft to rotate under the action of the winding motor. Moreover, the positioning hole facilitates the positioning and locking of the positioning rod during the locking process of the roller shutter door body, which facilitates buffering and improves the locking fit.

[0010] Preferably, there are two aluminum alloy surface layers in total, and slots and plates are respectively opened on opposite sides of the aluminum alloy surface layers. The plates are arranged in groups of two, and several groups of slots and plates are installed at equal intervals.

[0011] The above technical solution, with the use of two aluminum alloy layers, helps to improve the robustness and protection of the roller shutter door body. At the same time, the slots and plates help to limit the first and second reinforcing ribs respectively, improving stability during use and facilitating positioning and installation during production.

[0012] Preferably, the reinforcing ribs include a first reinforcing rib and a second reinforcing rib. The size and shape of the first reinforcing rib match the slot, and the size and shape of the second reinforcing rib match the gap between the two plates. Several sets of equally spaced steel wires are arranged between the first and second reinforcing ribs.

[0015] Through the above technical solution, during the process of the roller shutter door body moving down and locking, the positioning rod engages with the positioning hole, and the buffer spring contacts the rubber seat to provide buffering. The rubber seat and rubber sleeve are squeezed and deformed to improve the buffering effect. This is beneficial for buffering and protecting the roller shutter door body when it is locked, thereby avoiding damage caused by excessive impact force leading to excessive vibration force between the lower end of the roller shutter door body or components, and improving service life and protection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figure 1-6 As shown, the present invention provides an aluminum alloy roller shutter door with strong impact resistance, including a door frame 1, a winding box 2 provided on the top side of the door frame 1, a roller shutter door body 3 movably installed on the inner side of the door frame 1, the roller shutter door body 3 including an aluminum alloy surface layer 4 and reinforcing composite ribs 5, the inner side of the aluminum alloy surface layer 4 is provided with reinforcing composite ribs 5, a fixing plate 6 is fixedly installed at the lower end of the aluminum alloy surface layer 4, a slider 7 is provided on the right side of the fixing plate 6, and a positioning rod 8 is fixedly installed on the bottom side of the slider 7.

[0029] Specifically, a winding motor 201 is installed on the right side of the winding box 2, and a winding shaft is fixedly installed on the left end of the winding motor 201. Slide grooves 101 are respectively opened on opposite sides of the door frame 1. A positioning hole 102 is opened on the bottom side of the inner side of the slide groove 101, and a rubber seat 103 is fixedly installed on the bottom side of the inner side of the positioning hole 102. The advantages are that the winding motor 201 drives the winding shaft to rotate, facilitating the winding and unfolding of the roller shutter door body 3. Furthermore, the positioning hole 102 facilitates positioning and engagement with the positioning rod 8 during the locking process of the roller shutter door body 3, providing cushioning and improving the engagement tightness.

[0030] Specifically, there are two aluminum alloy surface layers 4, and slots 401 and plates 402 are respectively provided on opposite sides of the aluminum alloy surface layers 4. The plates 402 are arranged in pairs, and several sets of slots 401 and plates 402 are installed at equal intervals. The advantage is that the use of two aluminum alloy surface layers 4 improves the robustness and protective properties of the roller shutter door body 3. At the same time, the slots 401 and plates 402 help to limit the movement of the first reinforcing rib 501 and the second reinforcing rib 502 respectively, improving stability during use and facilitating positioning and installation during production.

[0031] Example 2:

[0032] like Figure 1-6 As shown, this is an improvement on the previous embodiment. Specifically, the reinforcing composite rib 5 includes a first reinforcing rib 501 and a second reinforcing rib 502. The size and shape of the first reinforcing rib 501 match the slot 401, and the size and shape of the second reinforcing rib 502 match the gap between the two slot plates 402. Several sets of equally spaced steel wires 503 are arranged between the first reinforcing rib 501 and the second reinforcing rib 502. The gap between the first reinforcing rib 501 and the second reinforcing rib 502 is filled with polystyrene foam, and the steel wires 503 are installed in a cross-shaped structure. The advantages are that the No. 1 reinforcing rib 501 and No. 2 reinforcing rib 502 set between the two aluminum alloy surface layers 4 can increase the overall strength of the roller shutter body 3. At the same time, the steel wire 503 and polystyrene foam filling between the No. 1 reinforcing rib 501 and No. 2 reinforcing rib 502 can help to buffer the impact and ensure the uniformity between the aluminum alloy surface layers 4, avoid damage caused by local impact concentration, and improve the overall impact resistance and safety of the roller shutter body 3.

[0033] Specifically, handles 601 are respectively provided on the front and rear sides of the fixed plate 6. The slider 7 is movably installed inside the slide groove 101.

A buffer spring 702 is fixedly installed on the bottom side of the rubber sleeve 701, and the buffer spring 702 is located outside the positioning rod 8. The advantage is that when the positioning rod 8 engages with the positioning hole 102 and the buffer spring 702 contacts the rubber seat 103, it provides buffering. The compression deformation of the rubber seat 103 and the rubber sleeve 701 further improves the buffering effect. This is beneficial for buffering protection when the roller shutter door body 3 is locked, thereby avoiding damage caused by excessive vibration at the lower end of the roller shutter door body 3 or between components due to large impact force, thus improving service life and protection.

[0034] During use, when the roller shutter body 3 moves downward to lock, the positioning rod 8 engages with the positioning hole 102, and the buffer spring 702 contacts the rubber seat 103 for cushioning. The rubber seat 103 and rubber sleeve 701 deform under pressure, further enhancing the cushioning effect. This provides cushioning protection when the roller shutter body 3 is locked, preventing damage caused by excessive impact force leading to excessive vibration at the lower end of the roller shutter body 3 or between components. This improves service life and protection. Furthermore, the use of two aluminum alloy surface layers 4 during use provides additional protection. This design improves the robustness and protective properties of the roller shutter door body 3. Furthermore, the No. 1 reinforcing rib 501 and No. 2 reinforcing rib 502 set between the two aluminum alloy surface layers 4 enhance the overall strength of the roller shutter door body 3. Additionally, the presence of steel wire 503 and polystyrene foam between the No. 1 reinforcing rib 501 and No. 2 reinforcing rib 502 helps to buffer impacts and ensure the uniformity of the aluminum alloy surface layers 4, preventing damage caused by concentrated local impact forces and improving the overall impact resistance and safety of the roller shutter door body 3.
