Description

Technical Field

[0001] This utility model belongs to the field of pipeline technology and relates to an adjustable marine elbow with lugs. Background Technology

[0002] An elbow is a pipe fitting used in a piping system to connect two pipes of the same or different nominal diameters, allowing the pipeline to bend at a certain angle. Piping systems have diverse applications, and are very common not only in buildings but also in large water transport vehicles such as ships. For the latter, due to their more complex internal structure, their installation is more complicated than that of buildings.

[0003] Specifically, since ships travel on water and are not as stable as buildings, reinforcement measures are needed for all connections in the pipeline system (especially at bends and wall penetrations). In response to the above situation, the current measures generally involve injecting sealant into the gaps at the wall penetrations, and then bonding the inner wall of the opening and the outer wall of the bend together after it has solidified.

[0004] However, due to the continuous swaying of the hull over a long period of time, the solidified sealant is constantly subjected to compression and stretching, which can easily cause cracks at the joint, resulting in connection failure at the elbow. In response to this situation, the existing technology further improves the elbow structure. Specifically, during the manufacturing of the elbow, an ear plate is integrally formed on the outside of the elbow, and one or more through holes are opened on the ear plate to penetrate its two sides. During assembly, the ear plate is abutted against the wall and fixed to the wall with screws, thereby ensuring the reliability of the elbow connection.

[0005] However, the use of this type of elbow is quite limited. For example, when installing this elbow on a ship's cabin wall with pre-drilled threaded holes, the twisted arrangement of the piping system causes the installation orientation of the elbow to be reversed, which makes it impossible for the through hole on the ear plate and the threaded hole on the cabin wall to be aligned, thus making it impossible to install the screw and fix the elbow. Its applicability is poor. Summary of the Invention

[0006] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an adjustable marine elbow with lugs. The technical problem to be solved by this utility model is: how to improve the applicability of the elbow.

[0007] The purpose of this utility model can be achieved through the following technical solution: an adjustable marine elbow with lugs, comprising a body and a lug plate with at least two positioning holes on its surface, characterized in that the lug plate is detachably connected to the body and the lug plate can rotate circumferentially along the body, and the two positioning holes are both strip-shaped holes and the length directions of the two positioning holes intersect.

[0008] Compared to existing technologies, the common feature is that they all include a two-part structure: a body and an ear plate. Based on this technology, this application connects the ear plate to the body in a detachable manner. The advantage of this is that during the installation of the elbow, the user can determine whether to install the elbow on the wall first and then install the ear plate, or to assemble the ear plate and the elbow first and then install the elbow on the wall. That is, the installation position of the ear plate can be assembled on the front or back of the wall as needed. Secondly, during the subsequent assembly process, the ear plate can rotate relative to the body around its circumference. Through this structure and this method, even if the elbow is twisted, the installer can rotate the ear plate to align the positioning holes on the ear plate with the threaded holes on the wall. Furthermore, this application further reduces the possibility of hole misalignment during the installation process by setting all the threaded holes on the ear plate as strip holes with intersecting length directions, effectively improving the installation applicability of this elbow.

[0009] In the aforementioned adjustable marine elbow with lugs, the lug plate is elliptical in shape. The body includes a socket section and a threaded section formed at one end of the socket section. An installation opening is provided at the center of the lug plate, and the inner diameter of the installation opening is larger than the outer diameter of the socket section. The lug plate is fitted onto the socket section through the installation opening. The threaded section of the body has an internal threaded connector made of stainless steel or copper, enabling precise threaded connections with other pipe fittings, ensuring a tight and secure connection. The socket section is designed for socket-fitting connections with pipe fittings, ensuring flexibility. Specifically, the lug plate is fitted onto the body through the installation opening on its surface, and its inner diameter is limited to be larger than the outer diameter of the socket section, ensuring that the lug plate can rotate after being fitted onto the socket section. It is worth noting that because the threaded section has a built-in internal threaded connector, its outer diameter is necessarily larger than that of the socket section.

[0010] In the aforementioned adjustable marine elbow with lugs, two strip-shaped holes are respectively opened at both ends of the lug plate. The lug plate itself is elliptical, and with the two strip-shaped holes at both ends of its surface, the length that each positioning hole can be opened is longer, thereby further reducing the installation limitations of the lug plate on the wall-mounted hole fixing.

[0011] In the aforementioned adjustable marine elbow with lugs, one of the positioning holes is perpendicular to the long axis of the lug plate, and the other positioning hole is perpendicular to the short axis of the lug plate. This allows the lug plate to have more adjustment space in both the lateral and longitudinal directions, ensuring that the hole positions correspond.

[0012] In the aforementioned adjustable marine elbow with lugs, the lug plate includes a plate body one with a groove one and a plate body two with a groove two. The side wall of the plate body one with the groove one has a snap-fit ​​part located on both sides of the groove one. The side wall of the plate body two with the groove two has a snap-fit ​​groove located on both sides of the groove two. The plate body one and the plate body two are connected by the snap-fit ​​part and the snap-fit ​​groove so that the groove one and the groove two surround to form the mounting opening. As a further solution, the ear plate can adopt a split structure. Specifically, the complete ear plate consists of a snap-fit ​​part on plate one and a snap-fit ​​groove on plate two, which fit together to form a complete mounting opening. With this design, after the main body is installed, the installer can hold plate one and plate two with both hands respectively, and while the main body is embedded in groove one and groove two, apply force to plate one and plate two to make the snap-fit ​​part snap into the snap-fit ​​groove, thereby improving the ease of installation of the ear plate.

[0013] Compared with existing technologies, this adjustable marine elbow with lugs has the following advantages:

[0014] 1. The ear plate is connected to the main body in a detachable manner, allowing the ear plate to rotate relative to the main body. This enables the positioning port on the ear plate to align with the threaded hole pre-drilled on the wall after rotation, resulting in greater installation applicability.

[0015] 2. All positioning holes are strip-shaped, with one along the long axis of the ear plate and the other along the short axis of the ear plate, ensuring more adjustment space and higher fault tolerance when installing the ear plate.

[0016] 3. The two separate plates are combined with a snap-fit ​​part and a snap-fit ​​groove to form an ear plate with an installation port, making assembly more convenient. Attached Figure Description

[0024] like Figure 1 As shown, this adjustable marine elbow with lugs includes a body 1 and lugs 2, combined with... Figure 2 The main body 1 includes an L-shaped socket section 11 and a threaded section 12 formed at one end of the socket section 11. The threaded section 12 has an internally threaded connector with internal threads tapped on its inner wall integrally formed inside, and the outer diameter of the threaded section 12 is larger than the outer diameter of the socket section 11.

[0025] Combination Figure 3 The ear plate 2 is elliptical in shape, and an installation opening 22 is provided at the center of its surface. The inner diameter of the installation opening 22 is larger than the socket section 11 of the body 1. Positioning holes 21 are provided at both ends of the plate surface. Each positioning hole 21 is elongated. One positioning hole 21 is perpendicular to the short axis of the ear plate 2, and the other positioning hole 21 is perpendicular to the long axis of the ear plate 2.

[0026] Combination Figure 4 and Figure 5 The ear plate 2 includes a plate body 23 with a groove 231 on one side and a plate body 24 with a groove 241 on one side. On the side wall of the plate body 23 with the groove 231, there are two snap-fit ​​parts 232 located on both sides of the groove 231 and protruding outward. On the side wall of the plate body 24 with the groove 241, there are snap-fit ​​grooves 242 located on both sides of the groove 241. The plate body 23 and the plate body 24 are engaged with the snap-fit ​​parts 232 and the snap-fit ​​grooves 242, so that the groove 231 and the groove 241 surround each other to form an installation opening 22.

[0027] Installation principle: After the installer inserts the main body 1 into the through hole opened in the wall, the socket section 11 and the threaded section 12 of the main body 1 are connected to other pipe fittings in the piping system. Then, the installer holds plate 1 23 and plate 2 24 and assembles them on the outside of the socket section 11 of the main body 1. The plate 1 23 and plate 2 24 are snapped together by the snap-fit ​​part 232 and snap-fit ​​groove 242, so that plate 1 23 and plate 2 24 are assembled to form ear plate 2. The installation opening 22 formed by the groove 1 231 and groove 2 241 is fitted on the outside of the socket section 11 of the main body 1. Then, the installer rotates the ear plate 2 according to the position of the threaded hole opened in the wall, so that the two positioning holes 21 and the two threaded holes on the ear plate 2 are aligned. Finally, the bolt is screwed in, so that the ear plate 2 and the main body 1 are fixed to the wall.
