Abstract
Description
Technical Field
[0001] This utility model relates to an eaves drainage component, specifically an eaves drainage component based on architectural design, and belongs to the technical field of eaves drainage components. Background Technology
[0002] Roof drainage components are a series of devices for collecting and discharging rainwater from roofs, including gutters, downpipes, and rain hoppers. They are used to prevent rainwater from damaging the building structure. When a building adopts an organized drainage system (which requires rainwater to be directed to the ground or drainage system in an orderly manner), especially when the roof area is large, the rainfall is heavy, or there are high requirements for the protection of walls and foundations and the cleanliness of the appearance, the building design will involve this component.
[0003] The existing utility model with authorization announcement number CN217924478U discloses an eaves drainage component based on building design. The entire eaves board is installed at the edge of the roof top through the installation component. The tension of the return spring pulls two clamping rods to hold the filter cover. At the same time, the horizontal plate of the connecting crossbar is rotated to abut against the filter cover and stabilize the filter cover. When rainwater flows along the eaves board and enters the connecting pipe and the drain pipe through the filter cover, the filter cover can filter large debris and prevent the drain pipe from being blocked.
[0004] While the aforementioned technical solutions can filter large debris and prevent blockages in the drain pipes, the drain pipe structures are generally quite long and prone to deformation or damage during use. This makes quick assembly and disassembly of the drain pipes inconvenient, hindering subsequent maintenance and replacement. Therefore, this paper proposes a roof drainage component based on architectural design. Utility Model Content
[0005] This utility model proposes an eaves drainage component based on architectural design to solve the problem that the lack of a quick-assembly and disassembly structure for drainage pipes in the prior art leads to inconvenience in quickly assembling drainage pipes and subsequent maintenance and replacement of drainage pipes.
[0006] This utility model is achieved through the following technical solution: an eaves drainage component based on architectural design, including an arc-shaped water collection shell, and a quick disassembly and assembly mechanism is provided below the arc-shaped water collection shell;
[0007] The quick-assembly and disassembly mechanism includes a main drain pipe, a lower connecting shell fixedly connected to the outer surface of the main drain pipe, a water guide pipe fixedly connected to the inner wall of the arc-shaped water collection shell, an upper connecting shell fixedly connected to the outer surface of the water guide pipe, the inner wall of the upper connecting shell contacting the outer surface of the lower connecting shell, two threaded rods being threadedly connected to the inner walls of the upper and lower connecting shells, and a hand-tightening block fixedly connected to the ends of the two threaded rods that are far apart from each other, and a first sealing ring fixedly connected to the outer surface of the lower connecting shell, the upper surface of the first sealing ring contacting the bottom surface of the upper connecting shell.
[0008] Specifically, an assembly plate is fixedly connected to the upper surface of the arc-shaped water collection shell, and the upper surface of the assembly plate has several identical assembly holes.
[0009] Furthermore, a second sealing ring is fixedly connected to the upper surface of the lower connecting shell and the top of the drainage main pipe. The upper surface of the second sealing ring contacts the bottom end of the water pipe and the inner top wall of the upper connecting shell, respectively.
[0010] Each of the threaded rods has an arc-shaped washer fitted on its outer surface, the inner wall of each arc-shaped washer is in contact with the outer surface of the upper mating shell, and the outer surface of each arc-shaped washer is in contact with the outer surface of the hand-tightening block.
[0011] Preferably, each of the hand-tightening blocks has an anti-slip sleeve fixedly connected to its outer surface, and each of the anti-slip sleeves has several identical anti-slip protrusions fixedly connected to its outer surface.
[0012] Furthermore, the inner bottom wall of the lower mating shell is fixedly connected with two positioning pins, and the outer surface of each positioning pin is in contact with the inner wall of the first sealing ring and the inner wall of the upper mating shell, respectively.
[0013] This utility model provides a roof drainage component based on architectural design, which has the following beneficial effects:
[0014] This roof drainage component, based on architectural design, utilizes the interplay of an arc-shaped water collection shell, a main drainage pipe, a lower connecting shell, a water guide pipe, an upper connecting shell, a first sealing ring, a threaded rod, and a hand-tightening block. The arc-shaped water collection shell can be installed under the eaves to easily collect rainwater. The lower connecting shell can be quickly inserted into the upper connecting shell, and turning the hand-tightening block allows the threaded rod to quickly penetrate and lock or remove the upper and lower connecting shells. Thus, connecting or removing the main drainage pipe and the water guide pipe can be quickly completed by simply turning the two hand-tightening blocks and inserting or removing the main drainage pipe. This improves the assembly efficiency of the main drainage pipe and the subsequent replacement efficiency, avoiding the problems of inconvenient assembly and subsequent maintenance and replacement of the drainage pipe structure due to the lack of a quick-disassembly and assembly structure.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0024] Please see Figures 1-4 This utility model provides a roof drainage component based on architectural design, including an arc-shaped water collection shell 1. A quick-release mechanism 2 is provided below the arc-shaped water collection shell 1. The quick-release mechanism 2 includes a drainage main pipe 201. A lower connecting shell 202 is fixedly connected to the outer surface of the drainage main pipe 201. An assembly plate 3 is fixedly connected to the upper surface of the arc-shaped water collection shell 1. Several identical assembly holes 4 are provided on the upper surface of the assembly plate 3. By providing the assembly holes 4, the assembly plate 3 can be fixed near the eaves with the help of external bolts or positioning column structures, so that the arc-shaped water collection shell 1 can catch the water flowing from the eaves.
[0025] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3A water guide pipe 203 is fixedly connected to the inner wall of the arc-shaped water collection shell 1. An upper connecting shell 204 is fixedly connected to the outer surface of the water guide pipe 203. A second sealing ring 5 is fixedly connected to the upper surface of the lower connecting shell 202 and the top of the drainage main pipe 201. The upper surface of the second sealing ring 5 contacts the bottom end of the water guide pipe 203 and the inner top wall of the upper connecting shell 204 respectively. By setting the second sealing ring 5, it can be placed between the drainage main pipe 201 and the water guide pipe 203, so that the water sealing at the joint of the two is good.
[0026] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 The inner wall of the upper mating shell 204 is in contact with the outer surface of the lower mating shell 202. The inner walls of the upper mating shell 204 and the lower mating shell 202 are connected by two threaded rods 206. A hand-tightening block 207 is fixedly connected to the two threaded rods 206 at their far ends. An arc-shaped washer 9 is fitted on the outer surface of each threaded rod 206. The inner wall of each arc-shaped washer 9 is in contact with the outer surface of the upper mating shell 204, and the outer surface of each arc-shaped washer 9 is in contact with the outer surface of the hand-tightening block 207. By setting the arc-shaped washer 9, it can be placed between the upper mating shell 204 and the hand-tightening block 207 to increase the contact area between the two, thereby increasing the tightening effect of the threaded rod 206.
[0027] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 A first sealing ring 205 is fixedly connected to the outer surface of the lower connecting shell 202. An anti-slip sleeve 7 is fixedly connected to the outer surface of each hand-tightening block 207. Several identical anti-slip protrusions 8 are fixedly connected to the outer surface of each anti-slip sleeve 7. By setting the anti-slip protrusions 8, the anti-slip property of the outer surface of the anti-slip sleeve 7 can be increased. By setting the anti-slip sleeve 7 and the anti-slip protrusions 8, the anti-slip property of the outer surface of the hand-tightening block 207 can be increased together.
[0028] Please refer to this carefully. Figure 2 and Figure 3 The upper surface of the first sealing ring 205 contacts the bottom surface of the upper mating shell 204. Two positioning pins 6 are fixedly connected to the inner bottom wall of the lower mating shell 202. The outer surface of each positioning pin 6 contacts the inner wall of the first sealing ring 205 and the inner wall of the upper mating shell 204 respectively. By setting the positioning pins 6, the positioning effect of the lower mating shell 202 and the upper mating shell 204 can be increased when they are spliced together, thereby increasing the accuracy of the subsequent threaded rod 206 penetrating the upper mating shell 204 and the lower mating shell 202.
[0029] When this utility model is in use: First, the arc-shaped water collection shell 1 is fixed under the eaves through the mounting hole 4 of the mounting plate 3. The rainwater collected flows into the water guide pipe 203 along the inner wall of the arc-shaped water collection shell 1. The water guide pipe 203 and the main drainage pipe 201 are connected through the upper connecting shell 204 and the lower connecting shell 202. The first sealing ring 205 on the outer surface of the lower connecting shell 202 contacts the bottom surface of the upper connecting shell 204. The second sealing rings 5 at the top of the lower connecting shell 202 and the main drainage pipe 201 respectively contact the bottom end of the water guide pipe 203 and the inner top wall of the upper connecting shell 204. The double seal ensures that the connection does not leak.
[0030] When installing the main drainage pipe 201, the lower connecting shell 202 is inserted into the upper connecting shell 204. The positioning pin 6 on the inner bottom wall of the lower connecting shell 202 is embedded in the inner wall of the upper connecting shell 204 to achieve precise alignment. Then, the threaded rod 206 is passed through the corresponding threaded holes of the upper connecting shell 204 and the lower connecting shell 202. The hand-tightening block 207 is rotated to complete the fixation. The arc-shaped washer 9 on the outer surface of the threaded rod 206 increases the contact area between the hand-tightening block 207 and the upper connecting shell 204, improving the connection stability.
[0031] When disassembling or replacing the main drainage pipe 201, rotate the hand-tightening block 207 in the reverse direction to disengage the threaded rod 206 from the threaded hole. The anti-slip sleeve 7 and anti-slip protrusion 8 on the outer surface of the hand-tightening block 207 increase the friction and facilitate operation. After removing the threaded rod 206, directly pull the lower connecting shell 202 out of the upper connecting shell 204 to separate the main drainage pipe 201 from the water guide pipe 203. The entire process does not require complicated tools, achieving quick disassembly and assembly, and facilitating later maintenance. The design of the entire roof drainage component based on the building design effectively solves the problem of inconvenience in quickly assembling the drainage pipe structure and subsequent maintenance and replacement of the drainage pipe structure due to the lack of a quick disassembly and assembly structure for the drainage pipe structure.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
