Description

Technical Field

[0001] This invention relates to the field of roller shutter technology, specifically to a roller shutter door cover. Background Technology

[0002] A roller shutter door is a door with multiple articulated door panels linked together, which rotate up and down within a fixed track, centered on a roller at the top of the door.

[0003] Existing roller shutter doors have special shields on the outside of the retraction area to provide some protection for the internal roller shutter. However, roller shutter door shields are generally one-piece structures that need to be customized according to the size of the user's store. When replacing them, the entire unit needs to be replaced, which is not only cumbersome to disassemble and install, but also results in some economic losses when replacing the entire unit. Summary of the Invention

[0004] The purpose of this invention is to provide a roller shutter door cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a roller shutter door cover, comprising an outer baffle and two bottom baffles. An extension base plate extending to the left is installed at the lower end of the outer baffle. An extension assembly is installed at the left end of the extension base plate. A roller shutter conveying groove is formed at the upper end of the extension assembly. A second connecting hook plate is provided at the upper end of the outer baffle. A first connecting hook plate is provided at the lower right end of the bottom baffle. The two first connecting hook plates and the second connecting hook plate are connected by bolts. The left end of the bottom baffle is connected to the wall by fixing bolts. The outer baffle and the bottom baffle are detachably connected by the first connecting hook plate and the second connecting hook plate. Visually, it is a one-piece molding, which is aesthetically pleasing. Furthermore, the outer baffle and the bottom baffle can be disassembled and separated, making disassembly easier.

[0006] Preferably, the extension component includes an extension plate, a mounting block, and a slot. A slot is installed at the upper end of the left edge of the extension base plate, and a mounting block is installed at the right edge of the extension plate. A slot adapted to the slot is provided at the lower end of the mounting block. The extension component and the extension base plate can be connected together by engaging the slot and the slot together.

[0007] Preferably, the upper ends of both bottom baffles are provided with grooves, and an extension component is installed inside the two grooves. The extension component can enhance the connection strength between the two bottom baffles, and can be expanded or contracted according to the user's needs, thereby changing the distance between the two bottom baffles. While enhancing the connection strength, the two bottom baffles can still be used with outer baffles of different sizes.

[0008] Preferably, the extension assembly includes a fixed rod, a telescopic plate, a partition, a sleeve, and a sliding groove. The fixed rod is fixedly installed inside the groove. A telescopic plate is installed at one end of each of the two fixed rods facing each other. A partition is installed at one end of each of the two telescopic plates facing each other. A sleeve is fitted over the two telescopic plates. A sliding groove is formed inside the sleeve. The opening size of the two ends of the sliding groove is smaller than the size of the partition.

[0009] Preferably, each of the two telescopic plates has an installation groove inside, and the openings of the two installation grooves are opposite to each other.

[0010] Preferably, the right-side mounting groove has limit grooves on both the left and right sidewalls. A slider is slidably connected inside the limit groove. A first sliding plate is installed inside the two sliders. An upward upper limit plate is installed on the left edge of the upper end of the first sliding plate.

[0011] Preferably, a second sliding plate is slidably connected inside the mounting groove on the left side. A downward limiting plate is installed at the upper right edge of the second sliding plate. The connection structure and connection relationship between the left mounting groove and the second sliding plate are consistent with the connection structure between the right mounting groove and the first sliding plate. Similarly, the second sliding plate can slide inside the left mounting groove and cannot be completely detached from the left mounting groove.

[0012] Preferably, the upper limit plate and the lower limit plate on the left are snapped together. The upper limit plate and the lower limit plate are the same size and both are smaller than the opening size of the mounting groove. By snapping together the upper limit plate and the lower limit plate, the connection strength of the two telescopic plates can be enhanced, and the two telescopic plates can be prevented from completely separating.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This roller shutter door cover features an outer baffle with two bottom baffles installed on its upper end. The two bottom baffles are threaded to the wall. An extension base plate is installed at the lower end of the outer baffle, and an extension assembly is connected to the left end of the extension base plate. The upper end of the extension assembly has a roller shutter conveying groove. A roller shutter door is installed inside the outer baffle, and the roller shutter door can be rolled up or extended through the roller shutter conveying groove. The outer baffle and the bottom baffles are detachably connected by a first connecting hook plate and a second connecting hook plate. From the appearance, it is a one-piece molding, which is more aesthetically pleasing. The outer baffle and the bottom baffles can be disassembled and separated, making disassembly easier and replacement unnecessary, thus saving economic costs.

[0015] 2. This roller shutter door cover enhances the connection strength between the two bottom baffles by setting an extension component between them. The extension component can be expanded or contracted according to the user's needs, thereby changing the distance between the two bottom baffles. While enhancing the connection strength, the two bottom baffles can still be used with outer baffles of different sizes.

[0016] 3. This roller shutter door cover has a first sliding plate and a second sliding plate inside the telescopic assembly. An upper limit plate is installed at the upper end of the first sliding plate, and a lower limit plate is installed at the lower end of the second sliding plate. The connection between the upper limit plate and the lower limit plate can enhance the connection strength of the two telescopic plates and prevent the two telescopic plates from completely separating.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] like Figures 1 to 5 As shown, the roller shutter door cover in this embodiment includes an outer baffle 1 and two bottom baffles 2. The outer baffle 1 faces outward, one end of the bottom baffle 2 is connected to the outer baffle 1, and the other end of the bottom baffle 2 is connected to the wall. An extension base plate 17 extending to the left is installed at the lower end of the outer baffle 1, and an extension component 5 is installed at the left end of the extension base plate 17. The length of the extension base plate 17 plus the extension component 5 is the same as the length of the bottom baffle 2. The extension base plate 17 and the extension component 5 can divide the external environment below. A roller shutter conveying groove 7 is provided at the upper end of the extension component 5. A roller shutter door is installed inside the outer baffle 1. The roller shutter door can be rolled up or extended through the roller shutter conveying groove 7. When needed, the roller shutter door is lowered from the roller shutter conveying groove 7 by a rolling device. When not needed, it is rolled up by a rolling device. The rolling device retracts the roller shutter door. The roller shutter door needs to pass through the roller shutter conveyor trough 7 during the retraction process. It should be noted that a limiting structure needs to be set at the lowest end of the roller shutter door to prevent the roller shutter door from completely passing through the roller shutter conveyor trough 7. The upper end of the outer baffle 1 is provided with a second connecting hook plate 16, and the lower right end of the bottom baffle 2 is provided with a first connecting hook plate 15. The second connecting hook plate 16 and the first connecting hook plate 15 are in a snap-fit ​​connection relationship. From the appearance, it is a one-piece molding, which is more aesthetically pleasing. The internal connection needs to be reinforced with bolts to strengthen the connection. The two first connecting hook plates 15 and the second connecting hook plate 16 are connected by bolts. The left end of the bottom baffle 2 is connected to the wall by fixing bolts 4. The fixing bolts 4 connect the bottom baffle 2 to the wall together to enhance the connection strength.

[0027] Specifically, the extension component 5 includes an extension plate 501, a mounting block 502, and a slot 503. A slot 6 is installed at the upper end of the left edge of the extension base plate 17, and a mounting block 502 is installed at the right edge of the extension plate 501. A slot 503 adapted to the slot 6 is provided at the lower end of the mounting block 502. By engaging the slot 503 with the slot 6, the extension plate 501 and the extension base plate 17 are connected together. It should be noted that after the slot 6 and the slot 503 are engaged, bolts need to be used to pass through the mounting block 502 and the slot 6 to enhance the connection strength.

[0028] Furthermore, the upper ends of both bottom baffles 2 are provided with grooves 8, and extension components 3 are installed in the interior of both grooves 8. By setting extension components 3 between the two bottom baffles 2, the connection strength of the two bottom baffles 2 is enhanced, and the extension components 3 can be expanded or contracted according to the user's needs, thereby changing the distance between the two bottom baffles 2. While enhancing the connection strength, the two bottom baffles 2 can still be used for outer baffles 1 of different sizes.

[0029] Furthermore, the extension assembly 3 includes a fixed rod 301, a telescopic plate 302, a partition 303, a sleeve 304, and a sliding groove 305. The fixed rod 301 is fixedly installed inside the groove 8. A telescopic plate 302 is installed at one end of each of the two fixed rods 301 facing each other. A partition 303 is installed at one end of each of the two telescopic plates 302 facing each other. A sleeve 304 is fitted over the two telescopic plates 302. A sliding groove 305 is formed inside the sleeve 304. The openings at both ends of the sliding groove 305 are smaller than the size of the partition 303. The two fixed rods 301 and the two telescopic plates 302 are all the same size. The two telescopic plates 302 can slide in the sliding groove 305 inside the sleeve 304. Pulling the telescopic plate 302 outward can increase the distance between the two bottom baffles 2, and retracting the telescopic plate 302 inward can decrease the distance between the two bottom baffles 2. Since the size of the partition plate 303 is larger than the opening size of the sliding groove 305, it can prevent the telescopic plate 302 from completely disengaging from the sliding groove 305 and avoid the phenomenon of the telescopic plate 302 falling off.

[0030] Furthermore, each of the two telescopic plates 302 has an installation groove 9 inside. The openings of the two installation grooves 9 are opposite to each other. The two installation grooves 9 are the same size and material, and their opening directions are opposite.

[0031] Furthermore, limit grooves 10 are provided on both the left and right sidewalls inside the right mounting groove 9. A slider is slidably connected inside the limit groove 10. A first sliding plate 11 is installed inside the two sliders. An upward upper limit plate 12 is installed on the upper left edge of the first sliding plate 11. By setting the limit groove 10, the slider can slide laterally inside the limit groove 10, but the slider cannot detach from the inside of the limit groove 10. A first sliding plate 11 is installed inside the two sliders, so that the first sliding plate 11 can slide inside the right mounting groove 9. Similarly, since the first sliding plate 11 is connected to the slider, the first sliding plate 11 cannot be completely detached from the inside of the mounting groove 9. It can only slide laterally inside the mounting groove 9 under the action of external force.

[0032] Furthermore, a second sliding plate 13 is slidably connected inside the left mounting groove 9. A downward limiting plate 14 is installed at the upper right edge of the second sliding plate 13. The connection structure and connection relationship between the left mounting groove 9 and the second sliding plate 13 are consistent with the connection structure between the right mounting groove 9 and the first sliding plate 11. Similarly, the second sliding plate 13 can slide inside the left mounting groove 9 and cannot be completely detached from the left mounting groove 9.

[0033] Furthermore, the upper limit plate 12 and the lower limit plate 14 on the left side are engaged. The upper limit plate 12 and the lower limit plate 14 are the same size and both are smaller than the opening size of the mounting groove 9. A first sliding plate 11 and a second sliding plate 13 are provided inside the telescopic assembly. The upper limit plate 12 is installed at the upper end of the first sliding plate 11, and the lower limit plate 14 is installed at the lower end of the second sliding plate 13. By engaging the upper limit plate 12 and the lower limit plate 14, the connection strength of the two telescopic plates 302 can be enhanced, preventing the two telescopic plates 302 from completely separating. The fact that the upper limit plate 12 and the lower limit plate 14 are the same size and both are smaller than the opening size of the mounting groove 9 allows the upper limit plate 12 and the lower limit plate 14 to slide freely inside the mounting groove 9.

[0034] The usage method of this embodiment is as follows: the outer baffle 1, bottom baffle 2, extension component 3, extension component 5, and extension plate 501 are all made of the same material. Two bottom baffles 2 are installed on the upper end of the outer baffle 1 and are threaded to the wall. An extension base plate 17 is installed on the lower end of the outer baffle 1. An extension component 5 is connected to the left end of the extension base plate 17. A roller shutter conveying groove 7 is opened on the upper end of the extension component 5. A roller shutter door is installed inside the outer baffle 1. The roller shutter door can be rolled up or extended through the roller shutter conveying groove 7. The outer baffle 1 and the bottom baffle 2 are detachably connected by a first connecting hook plate 15 and a second connecting hook plate 16. From the appearance, it is a one-piece molding, which is more beautiful. The two bottom baffles 2 are connected by the extension component 3 to enhance the connection strength of the two bottom baffles 2.

[0035] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
