Description

Technical Field

[0001] This utility model belongs to the field of polyethylene pipe diameter reduction connection technology, and particularly relates to an adjustable sealing joint for polyethylene pipe diameter reduction connection. Background Technology

[0002] Polyethylene pipes are plastic pipes made from polyethylene resin. They have core advantages such as being lightweight, corrosion-resistant, and easy to install, and are widely used in water supply, gas supply, drainage and other fields.

[0003] Because conventional polyethylene pipe reducing coupling devices have a customized angle and cannot be flexibly adjusted as needed, their practicality is relatively low.

[0004] To address this issue, we propose an adjustable sealing joint for reducing the diameter of polyethylene pipes. Utility Model Content

[0005] The purpose of this invention is to address the problem of low practicality of conventional polyethylene pipe diameter reducing and connecting devices, and to propose an adjustable sealing joint for polyethylene pipe diameter reducing connections.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable sealing joint for reducing the diameter of polyethylene pipes includes an arc-shaped hose, one end of which is fitted with a first flange, and the other end of which is fitted with an elastic clamp. A screw is installed on the side of the elastic clamp, and an arc-shaped steel pipe is inserted inside the arc-shaped hose. Loosening the screw releases the elastic clamp, which in turn releases the arc-shaped hose, causing the arc-shaped hose to release the arc-shaped steel pipe. Adjusting the extension of the arc-shaped steel pipe changes the connection angle. Tightening the screw tightens the elastic clamp, which in turn tightens the arc-shaped hose, thus sealing and fixing the arc-shaped hose and arc-shaped steel pipe, facilitating adjustment of the connection angle.

[0007] Preferably, the arc-shaped hose includes a hose body, one end of which has a limiting groove, and the other end of which is fixedly connected to a retaining ring. The first flange is fitted onto the hose body, and the retaining ring blocks the outside of the first flange. The retaining ring blocks the first flange from detaching from the arc-shaped hose, and the limiting groove constrains the elastic clamp, preventing the elastic clamp from detaching from the arc-shaped hose.

[0008] Preferably, the arc-shaped steel pipe includes a steel pipe body, one end of which is fixedly connected to a second flange, and the steel pipe body is inserted into the hose body. When the elastic clamp loosens the hose body, the hose body loosens from the steel pipe body; when the hose body is tightened, the hose body acts on the steel pipe body, sealing and fixing the steel pipe body and the hose body together, facilitating the locking or unlocking of the arc-shaped hose and arc-shaped steel pipe.

[0009] Preferably, the elastic band includes a band body, with mounting rings fixedly connected to both ends of the band body, and the screw is installed inside the mounting rings. When the screw is loosened from the mounting rings, the mounting rings loosen the band body. When the screw is tightened, the mounting rings act on the band body, causing the band body to tighten the arc-shaped tubing.

[0010] Preferably, the elastic hoop further includes a shovel block, which is fixedly connected to one end of the hoop body. When the hoop body is tightened, the shovel block digs into the inner wall of the other end of the hoop body, reducing the pressure loss gap in the arc-shaped hose.

[0011] Preferably, the elastic hoop further includes a pressure block, which is in movable contact with the shovel block and is fixedly connected to the hoop body. During tightening, the pressure block is used to squeeze the shovel block inward, increasing the uniformity of the inward squeezing force.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Loosen the screws to release the spring clamp, which in turn releases the curved hose, which then releases the curved steel pipe. Adjust the extension of the curved steel pipe to change the docking angle. Tighten the screws to tighten the spring clamp, which in turn tightens the curved hose, thus sealing and fixing the curved hose and steel pipe for easy adjustment of the docking angle.

[0013] 2. When the elastic clamp loosens the hose body, it loosens the steel pipe body. When the hose body is tightened, it acts on the steel pipe body to seal and fix the steel pipe body to the hose body, making it easy to lock or unlock the arc-shaped hose and arc-shaped steel pipe.

[0016] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0017] like Figure 1 As shown, an adjustable sealing joint for reducing the diameter of a polyethylene pipe includes an arc-shaped hose 2, one end of which is fitted with a first flange 5, and the other end of which is fitted with an elastic clamp 4. A screw 1 is installed on the side of the elastic clamp 4, and an arc-shaped steel pipe 3 is inserted inside the arc-shaped hose 2. Loosening the screw 1 releases the elastic clamp 4, which in turn releases the arc-shaped hose 2, causing the arc-shaped hose 2 to release the arc-shaped steel pipe 3. Adjusting the extension of the arc-shaped steel pipe 3 changes the mating angle. Tightening the screw 1 tightens the elastic clamp 4, which in turn tightens the arc-shaped hose 2, thus sealing and fixing the arc-shaped hose 2 and the arc-shaped steel pipe 3.

[0018] like Figure 1 and 2 As shown, the arc-shaped hose 2 includes a hose body 21. A limiting groove 22 is formed on the outside of one end of the hose body 21, and a retaining ring 23 is fixedly connected to the other end of the hose body 21. A first flange 5 is sleeved on the hose body 21, and the retaining ring 23 is positioned outside the first flange 5. The retaining ring 23 prevents the first flange 5 from detaching from the arc-shaped hose 2, and the limiting groove 22 constrains the elastic clamp 4, preventing the elastic clamp 4 from detaching from the arc-shaped hose 2.

[0019] like Figure 1 , 2 As shown in Figure 3, the arc-shaped steel pipe 3 includes a steel pipe body 31, one end of which is fixedly connected to a second flange 32. The steel pipe body 31 is inserted inside the hose body 21. When the elastic clamp 4 loosens the hose body 21, the hose body 21 loosens the steel pipe body 31. When the hose body 21 is tightened, it acts on the steel pipe body 31 through the hose body 21, so that the steel pipe body 31 and the hose body 21 are sealed and fixed.

[0020] like Figure 1 and 4As shown, the elastic clamp 4 includes a clamp body 41, with mounting rings 42 fixedly connected to both ends of the clamp body 41. Screws 1 are installed inside the mounting rings 42. When screws 1 loosen the mounting rings 42, the mounting rings 42 loosen the clamp body 41. After screws 1 are tightened, the mounting rings 42 act on the clamp body 41, causing the clamp body 41 to tighten the arc-shaped tubing 2.

[0021] like Figure 1 and 4 As shown, the elastic hoop 4 also includes a shovel block 43, which is fixedly connected to one end of the hoop body 41. When the hoop body 41 is tightened, the shovel block 43 shovels into the inner wall of the other end of the hoop body 41, reducing the pressure loss gap of the arc-shaped hose 2.

[0022] like Figure 1 and 4 As shown, the elastic hoop 4 also includes a pressure block 44, which is in movable contact with the shovel block 43 and is fixedly connected to the hoop body 41. During the tightening process, the pressure block 44 is used to press the shovel block 43 inward, increasing the uniformity of the inward pressing force.

[0023] Working principle: Loosen screw 1 to release the elastic clamp 4, which in turn releases the arc-shaped hose 2, which in turn releases the arc-shaped steel pipe 3. Adjust the extension of the arc-shaped steel pipe 3 to change the docking angle. Tighten screw 1 to tighten the elastic clamp 4, which in turn tightens the arc-shaped hose 2, thus sealing and fixing the arc-shaped hose 2 and the arc-shaped steel pipe 3.

[0024] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0025] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
