Description

Technical Field

[0001] This utility model relates to the field of roof drainage, and more specifically, it relates to a roof drainage structure. Background Technology

[0002] Roof drainage structures are groove systems installed along the edges of roofs, commonly known as roof gutters. They are primarily used to collect and guide rainwater, preventing it from flowing directly down the walls or accumulating on the roof.

[0003] The drainage gutter at the edge of the roof is usually quite long, making it inconvenient to install it directly on the edge. Currently, the drainage gutter is typically divided into multiple sections, which are then spliced ​​together at the edge of the house to form a complete drainage gutter. The drainage gutter components have a U-shaped cross-section, and the gutter is spliced ​​from top to bottom. During splicing, sealant needs to be applied to the inside of the drainage gutter components to ensure a tight seal between them. However, existing drainage gutters are installed too close to the eaves, which can easily interfere with the assembly process.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roof drainage structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a roof drainage structure, comprising several drainage ditch components with a U-shaped cross section, the drainage ditch components comprising a fixed section and a splicing section, the two ends of the splicing section being fixed to two fixed sections respectively, an installation rod being provided on one side of the fixed section, the end of the installation rod facing away from the fixed section being fixedly connected to the outer wall of the building, the length of the installation rod being retractable, the splicing section comprising a flexible part and two rigid parts, the two rigid parts being located at both ends of the flexible part respectively.

[0007] The present invention is further configured such that: the mounting rod includes a fixed rod and a sliding rod, one end of the fixed rod is fixedly connected to the outer wall of the house, a sliding groove is provided on the fixed rod, the sliding rod is slidably connected in the sliding groove, a hanging block is provided on the end of the sliding rod facing away from the fixed rod, and the fixed section is snapped onto the hanging block.

[0008] The present invention is further configured such that: a groove is provided on one side of the sliding rod, a limiting block is slidably connected in the groove, a compression spring is provided in the groove, the compression spring provides a force to the limiting block to slide away from the bottom of the groove, and a groove communicating with the sliding groove is provided on the outer wall of the fixed rod, and the limiting block restricts the sliding rod from sliding away from the mounting rod by being inserted into the groove.

[0009] The present invention is further configured such that the cross-section of the limiting block is a right-angled triangle, and when the sliding rod slides inward to the limiting position, the limiting block is embedded in the groove.

[0010] The present invention is further configured such that: a through hole is provided on the side wall of the mounting rod, a limit hole is provided on the sliding rod, and a limit pin for inserting into the limit hole is provided in the through hole; when the sliding rod slides outward to the limit position, the through hole is aligned with the limit hole.

[0011] The present invention is further configured such that a glue-dropping groove is provided on the inner peripheral wall of the fixed section.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The fixed sections are secured to the mounting rods, and then the splicing sections are installed between the two fixed sections. Because the mounting rods are relatively long, the end of the mounting rod facing away from the house is not located under the eaves, so that the installation of the fixed sections and splicing sections is not interfered with by the eaves. After all the splicing sections are spliced ​​with the fixed sections, the mounting rods are retracted, causing the entire drainage ditch to move towards the underside of the eaves, ensuring the drainage ditch's water collection effect. The mounting rods are retracted one by one. During the retraction process, the flexible parts can deform and bend with the movement of the fixed sections, thereby reducing the impact on the retraction of the mounting rods.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Roof drainage structure, such as Figure 1 and Figure 2As shown, the system includes several U-shaped drainage ditch components. Each component comprises a fixed section 1 and a connecting section, which are alternately arranged. The two ends of the connecting section are fixed to two fixed sections 1 respectively. A mounting rod is provided on one side of each fixed section 1. The end of the mounting rod facing away from the fixed section 1 is fixedly connected to the exterior wall of the building. The length of the mounting rod is retractable. The connecting section includes a flexible part 2 and two rigid parts 3, located at opposite ends of the flexible part 2. During installation, the mounting rod is first fixed to the exterior wall of the building using expansion bolts, at its longest length. The fixed section 1 is then fixed to the mounting rod, and the connecting section is installed between the two fixed sections 1. Because the mounting rod is relatively long at this point, the end of the mounting rod facing away from the building is not located below the eaves. This design ensures that the installation of the fixed section 1 and the splicing section is not interfered with by the eaves. The inner circumferential wall of the fixed section 1 has a glue-feeding groove 11. By squeezing sealant into the glue-feeding groove 11, the sealant is prevented from flowing and provides feedback, facilitating the application of the sealant. After all the splicing sections are spliced ​​with the fixed section 1, the installation rods are retracted, causing the entire drainage ditch to move towards the eaves, ensuring the drainage ditch's water-receiving effect. The number of fixed sections 1 equals the number of installation rods, and each installation rod corresponds to one fixed section 1. The installation rods are retracted one by one. During the retraction process, the flexible part 2 can deform and bend along with the movement of the fixed section 1, thereby reducing the impact on the retraction of the installation rods. In this embodiment, the flexible part 2 is made of flexible plastic.

[0020] like Figure 2 and Figure 3As shown, the mounting rod includes a fixed rod 4 and a sliding rod 5. One end of the fixed rod 4 is fixedly connected to the outer wall of the house by an expansion bolt. A sliding groove 6 is opened on the side of the fixed rod 4 facing away from the house, and the sliding rod 5 is slidably connected in the sliding groove 6. A hanging block 7 is provided on the end of the sliding rod 5 facing away from the fixed rod 4. The fixed section 1 is snapped onto the hanging block 7. A fixing ring is fixedly connected to one side of the fixed section 1. By snapping the hanging block 7 into the fixing ring, the fixed section 1 and the mounting rod are snapped together, which fixes the fixed section 1 and facilitates its installation. The sliding rod 5 slides in the fixed rod 4, which allows the entire mounting rod to retract. A groove is opened on one side of the sliding rod 5, and a limit block 8 is slidably connected in the groove. A compression spring is provided in the groove, and the compression spring provides a force to the limit block 8 to slide away from the bottom of the groove. The two ends of the compression spring are respectively connected to the groove. The bottom of the trough and the limiting block 8 are fixed. The outer wall of the fixing rod 4 is provided with a groove 9 that communicates with the sliding groove 6. The limiting block 8 restricts the sliding rod 5 from sliding away from the installation rod by engaging with the groove 9. After the entire drainage ditch is fixed, the sliding rod 5 is slid into the groove 9. The limiting block 8 will restrict the sliding rod 5 from sliding back, thus keeping the installation rod in a short length state. The cross-section of the limiting block 8 is set in a right-angled triangle. When the sliding rod 5 slides inward to the limiting position, the limiting block 8 is engaged in the groove 9. The side of the limiting block 8 facing the house is inclined. After the inclined surface abuts against the fixing rod 4, the entire limiting block 8 will retract into the groove, and the compression spring will be compressed until the limiting block 8 slides below the groove 9. At this time, the sliding rod 5 slides inward to the limiting position, and the limiting block 8 restricts the sliding rod 5 from sliding outward, thus ensuring the overall stability of the installation rod.

[0021] like Figure 2 and Figure 3 As shown, a through hole is also provided on the side wall of the mounting rod, and a limit hole is provided on the sliding rod 5. A limit pin 10 for insertion into the limit hole is provided in the through hole. When the sliding rod 5 slides outward to the limit position, the through hole and the limit hole are aligned. When the mounting rod is installed, the sliding rod 5 slides outward to the limit position. At this time, the limit pin 10 is located in the through hole and the limit hole. The limit pin 10 limits the mounting rod, so that the mounting rod can maintain the longest length. During the process of installing the fixed section 1 on the mounting rod, the length of the mounting rod will not change, ensuring the stability of the mounting rod. When people need to retract the mounting rod, they can simply pull out the limit pin 10.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
