Description

Technical Field

[0001] This utility model belongs to the field of elbow technology and relates to a downpipe elbow. Background Technology

[0002] An elbow is a pipe fitting used in a piping system to change the direction of the pipeline. The bending angle of an elbow is generally 45°, 90° or 135°. The inlet end of the elbow is connected to the inlet pipe, and the outlet end of the elbow is connected to the outlet pipe.

[0003] Existing elbows, such as the novel water pipe elbow disclosed in Chinese patent literature [Patent No.: 202222917048.1; Application Publication No.: CN218719610U], include a straight pipe I, a straight pipe II, and a bend. The straight pipe I, straight pipe II, and bend are hollow pipe bodies. The two ends of the bend are connected to the straight pipe I and straight pipe II respectively. It also includes an insert and a threaded pipe. The insert is embedded in the free ends of the straight pipe I and straight pipe II. The threaded pipe is threaded to the inner wall of the insert. The outer walls of the straight pipe I and straight pipe II are tangent to the outer wall of the bend. The threaded pipe includes a threaded section I, an operating section, and a threaded section II. Threaded section I is threaded to the insert. Threaded section I is connected to the operating section. The operating section is connected to threaded section II. The free end of threaded section I is provided with a receiving ring. The receiving ring is integrally connected to threaded section I. It also includes a sealing ring, which is fixed between the receiving ring and the insert.

[0004] In this type of water pipe elbow, one end of the elbow is connected to a straight pipe, and the other end is connected to a straight pipe. Water flows along the straight pipe, the elbow, and the straight pipe. The water flow changes direction in the elbow, meaning the elbow needs to withstand the impact of the water flow. The impact of the water flow on the elbow can cause it to wobble, leading to the elbow becoming loose or even falling off from the straight pipe. At the same time, the impact of the water flow on the elbow can also cause the water flow to break through the elbow, resulting in damage to the elbow. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a downpipe elbow. The technical problem solved is how to improve the strength of the elbow so that it will not be damaged.

[0006] The purpose of this utility model can be achieved through the following technical solution: a downpipe elbow, comprising an elbow with an inlet end and an outlet end, characterized in that it further comprises a base, the top of the base being fixedly connected to the outer wall of the elbow which is arc-shaped and convex, the two sides of the bottom of the base protruding outwards and disposed outside the elbow, each side of the bottom of the base having a fixing hole for fasteners to pass through, and the base having a plurality of filling grooves.

[0007] In use, place the base on the ground and then secure it to the ground using fasteners such as bolts or expansion screws inserted into the fixing holes. If necessary, concrete can be poured onto the base, embedding it into the filling groove to increase the stability of the base and prevent it from wobbling. This enhances the base's support and reinforcement of the bend, thereby increasing the strength of the bend and preventing damage. The top of the base is fixed to the outward-convex, arc-shaped outer wall of the bend, supporting the section of the bend exposed to rainwater impact, thus increasing the strength of that section and consequently the strength of the bend. The two outward-protruding sides of the base's bottom facilitate installation and fixation to the ground. The filling groove reduces the material required for base manufacturing, saving costs, and allows for better bonding between the base and concrete, improving the stability of the bend installation.

[0008] In the aforementioned downpipe elbow, the base includes several spaced-apart transverse support plates and several spaced-apart longitudinal support plates. The transverse and longitudinal support plates are perpendicular to each other, and the tops of both plates are fixedly connected to the outwardly convex outer wall of the elbow. This structure allows the base to be fixedly connected to the elbow in a crisscross pattern, ensuring the elbow's strength while reducing material usage.

[0009] In the aforementioned downpipe elbow, the width of the top of the transverse support plate is smaller than the outer diameter of the elbow, and the width of the bottom of the transverse support plate is equal to the outer diameter of the elbow. The transverse support plate, located at the front end of the base, is directly below the elbow. This structure makes the elbow compact, and the width of the bottom of the transverse support plate is equal to the outer diameter of the elbow, with an error tolerance of ±10mm.

[0010] In the aforementioned downpipe elbow, the rear end of the base has several connecting holes. These connecting holes are located between two adjacent transverse support plates, and the filling grooves on both sides of the rear end of the base are connected through these connecting holes. This structure allows the concrete embedded in the filling grooves to be joined together through the connecting holes, improving the stability of the base installation and thus increasing the strength of the elbow, preventing damage to the elbow.

[0011] In the aforementioned downpipe elbow, the longitudinal support plate is located at the front end of the base and directly below the elbow. The longitudinal support plate is positioned where the elbow is most subjected to the most intense rainwater impact, making that area less prone to damage, thereby increasing the elbow's strength and preventing damage.

[0012] In the aforementioned downpipe elbow, the elbow and the base are integrally molded by injection molding. This one-piece processing is convenient.

[0013] In the aforementioned downpipe elbow, the bottom of the base has several filling grooves that extend through the bottom of the base. This structure allows the concrete above and below the base to be integrated, improving the stability of the base installation and thus increasing the strength of the elbow, preventing damage to the elbow.

[0014] In the aforementioned drain pipe elbow, the bottom of the base is circular or a regular polygon.

[0015] Compared with the prior art, the downpipe elbow provided by this utility model has the following advantages:

[0016] 1. This downpipe elbow is equipped with a base to support the part of the elbow that is subjected to rainwater impact, thereby increasing the strength of that part of the elbow and preventing it from being damaged.

[0017] 2. This downpipe elbow is equipped with a filling groove, which serves two purposes: firstly, it reduces the material required for manufacturing the base, saving costs; secondly, it allows concrete to be embedded, enabling the base to better bond with the concrete, improving the elbow's installation firmness and thus enhancing its stability.

The base 2 is placed on the ground, and then expansion screws are inserted into the fixing hole 21 to fix the base 2 to the ground. Then, concrete is poured to embed the concrete into the filling groove 22. After the concrete solidifies, the installation of the elbow is completed.
