Description

Technical Field

[0001] This utility model relates to the field of pipe elbow technology, and in particular to a pipe elbow that is easy to install. Background Technology

[0002] Pipe elbows are key fittings in piping systems used to change the direction of fluid transport. Like a hub in a pipeline, their curved shape allows the pipeline to flexibly change its direction during installation to adapt to different layout requirements. For example, in scenarios such as building water supply and drainage and industrial pipeline transportation, elbows connect straight pipes, allowing the pipeline to bypass obstacles or extend along the designed path.

[0003] In existing technologies, once one end of a pipe elbow is fixed, it is difficult to adjust the angle independently. When an angle deviation occurs during on-site installation, personnel have to loosen the fixed end of the elbow for adjustment, or forcibly overtighten it due to the angle deviation. Whether it is repeated loosening or overtightening, it may damage the sealing structure at the connection, which may lead to water leakage problems in the pipeline system during operation. This not only wastes water resources but also makes it inconvenient for personnel to install the elbow and reduces the flexibility of the bend. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pipe elbow that is easy to install.

[0005] This utility model is achieved by the following technical solution: a pipe elbow that is easy to install, comprising a pipe, wherein an adjustment component is provided on the outer wall of the pipe, and a sealing component is provided inside the pipe;

[0006] The adjusting assembly includes a sealing plate groove, a sealing plate rotatably connected to the outer wall of the sealing plate groove, a hollow sealing column fixedly connected to the inner wall of the sealing plate, a first sealing plate fixedly connected to the outer wall of the end of the hollow sealing column away from the hollow sealing column, a bent tube contacting the outer wall of the first sealing plate, a first sealing plate groove being formed on the inner wall of the bent tube, a sealing ring fixedly connected to the end of the bent tube near the first sealing plate, a fixed column fixedly connected to the outer wall of the bent tube, a threaded rod slidably connected to the inner wall of the fixed column, a nut threadedly connected to the threaded rod, a first fixed column slidably connected to the outer wall of the threaded rod, and an adjusting groove being formed inside the first fixed column.

[0007] As a further improvement to the above solution, the sealing plate groove is formed on the inner wall of the pipe, the sealing plate is rotatably connected to the outer wall of the sealing plate groove, and the fixing column is fixedly connected to the outer wall of the pipe.

[0008] As a further improvement to the above solution, several adjustment slots are provided, and these adjustment slots are evenly distributed inside the fixed column.

[0009] The above technical solution involves creating a sealing groove on the inner wall of the pipe and another sealing groove on the inner wall of the bend. A sealing strip contacts the outer wall of the sealing groove, and the outer wall of the first sealing groove contacts the first sealing strip. A hollow sealing column connects the sealing strip and the first sealing strip, preventing the bend from detaching from the pipe and preventing water leakage. A sealing ring is fixed at the outer end of the bend, providing a secondary seal at the connection between the pipe and the bend. After the bend is adjusted, a threaded rod slides back onto the outer wall of the adjustment groove, and a nut compresses the pipe and bend, increasing the waterproof performance of the sealing ring. This allows for arbitrary angle adjustment of the bend without adjusting the pipe itself, ensuring the pipe's sealing performance, improving the flexibility of bend installation, reducing water waste, and facilitating installation.

[0010] As a further improvement to the above solution, the sealing assembly includes an inner groove, which is formed inside the pipe, and a limiting piece is slidably connected to the outer wall of the inner groove.

[0011] As a further improvement to the above solution, a sliding rod is fixedly connected to the outer wall of the limiting plate, the sliding rod is slidably connected inside the pipe, and a spring is sleeved on the outer wall of the sliding rod.

[0012] As a further improvement to the above solution, a sealing sheet 2 is fixedly connected to the end of the sliding rod away from the limiting sheet.

[0013] With the above technical solution, the limiting plate is fixed to the sliding rod, and a spring is sleeved on the outer wall of the sliding rod. The elasticity of the spring pushes the limiting plate, causing the limiting plate to slide on the outer wall of the inner groove. The sliding rod is fixed to the second sealing plate, so that the second sealing plate is always in contact with the inner wall of the pipe, avoiding rework and disassembly caused by forgetting to install the second sealing plate, and greatly improving installation efficiency and sealing reliability.

[0014] As a further improvement to the above solution, a limiting piece is fixedly connected to the outer wall of the pipe, and an inner nut is sleeved on the outer wall of the pipe.

[0015] The above technical solution involves fixing a limiting piece to the outer wall of the pipe, which limits the inner nut and prevents it from detaching from the pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention involves creating a sealing groove on the inner wall of the pipe and another sealing groove on the inner wall of the bend.

A hollow sealing column connects the sealing plate and the first sealing plate, preventing the bend from detaching from the pipe and preventing water leakage. A sealing ring is fixed at the outer end of the bend, providing a secondary seal at the connection between the pipe and the bend. After the bend is adjusted, a threaded rod slides back onto the outer wall of the adjustment groove, and a nut compresses the pipe and the bend, increasing the waterproof performance of the sealing ring. This allows for arbitrary angle adjustment of the bend without adjusting the pipe itself, ensuring the pipe's sealing performance, improving the flexibility of bend installation, reducing water waste, and facilitating installation.

[0018] This utility model uses a limiting plate to fix a sliding rod, and a spring is sleeved on the outer wall of the sliding rod. The elasticity of the spring pushes the limiting plate, causing the limiting plate to slide on the outer wall of the inner groove. The sliding rod is fixed to the second sealing plate, so that the second sealing plate is always in contact with the inner wall of the pipe, avoiding rework and disassembly caused by forgetting to install the second sealing plate, and greatly improving installation efficiency and sealing reliability.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment provides an easy-to-install pipe elbow, including a pipe 1, an adjustment component 2 on the outer wall of the pipe 1, and a sealing component 3 inside the pipe 1.

[0029] The adjusting assembly 2 includes a sealing plate groove 201, a sealing plate 202 rotatably connected to the outer wall of the sealing plate groove 201, a hollow sealing column 203 fixedly connected to the inner wall of the sealing plate 202, a sealing plate 204 fixedly connected to the outer wall of the end of the hollow sealing column 203 away from the hollow sealing column 203, a bent tube 205 contacting the outer wall of the sealing plate 204, a sealing plate groove 206 opened on the inner wall of the bent tube 205, a sealing ring 207 fixedly connected to the end of the bent tube 205 near the sealing plate 204, a fixing column 208 fixedly connected to the outer wall of the bent tube 205, a threaded rod 209 slidably connected to the inner wall of the fixing column 208, a nut 210 threadedly connected to the threaded rod 209, a fixing column 211 slidably connected to the outer wall of the threaded rod 209, and an adjusting groove 212 opened inside the fixing column 211.

[0030] The sealing groove 201 is formed on the inner wall of the pipe 1, the sealing plate 204 is rotatably connected to the outer wall of the sealing groove 206, and the fixing column 211 is fixedly connected to the outer wall of the pipe 1.

[0031] Several adjustment slots 212 are provided, and the several adjustment slots 212 are evenly distributed inside the fixed column 211.

[0032] The sealing assembly 3 includes an inner groove 301, which is opened inside the pipe 1, and a limiting piece 302 is slidably connected to the outer wall of the inner groove 301.

[0033] A sliding rod 303 is fixedly connected to the outer wall of the limiting plate 302. The sliding rod 303 is slidably connected inside the pipe 1. A spring 304 is sleeved on the outer wall of the sliding rod 303.

[0034] A sealing sheet 305 is fixedly connected to the end of the sliding rod 303 away from the limiting piece 302.

[0035] A limiting piece 4 is fixedly connected to the outer wall of pipe 1, and an inner nut 5 is sleeved on the outer wall of pipe 1.

[0036] The implementation principle of an easy-to-install pipe elbow in this embodiment is as follows: When the inner nut 5 is connected to the conveying pipeline, a limiting piece 4 is fixed on the outer wall of the pipeline 1. The limiting piece 4 limits the inner nut 5 to prevent it from detaching from the pipeline 1. At this time, the personnel detach the nut 210 from the threaded rod 209, and slide the threaded rod 209 on the inner wall of the adjusting groove 212 and the fixing column 208. At this time, the fixing column 208 is released, and the elbow 205 can be rotated at any angle by the fixing column 208. At the same time, a sealing plate groove 201 is opened on the inner wall of the pipeline 1, and a sealing plate groove 206 is opened on the inner wall of the elbow 205. The outer wall of the sealing plate groove 201 contacts the sealing plate 202, and the outer wall of the sealing plate groove 206 contacts the sealing plate 204. The sealing plate 202 and the sealing plate 204 are connected by the hollow sealing column 203, thereby preventing the elbow 205 from detaching from the pipeline 1 and preventing water leakage.

[0037] The hollow sealing column 203 is made of rubber, and a sealing ring 207 is fixed to the outer end of the bend 205. The sealing ring 207 can provide a secondary seal at the connection between the pipe 1 and the bend 205. After the bend 205 is adjusted, it slides back onto the outer wall of the adjusting groove 212 through the threaded rod 209. At this time, the nut 210 compresses the pipe 1 and the bend 205, increasing the waterproof performance of the sealing ring 207. This allows the bend 205 to be adjusted at any angle without adjusting the pipe 1, ensuring the sealing of the pipe 1 and improving the installation flexibility of the bend 205. This reduces water waste and facilitates installation.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
