Description

Technical Field

[0001] This patent relates to the technical field of water conservancy pipelines, specifically a water conservancy pipeline that is easy to connect. Background Art

[0002] Some water conservancy pipes for transporting sewage are used to transport sewage containing debris. The pipes need to be disassembled in sections regularly to clean the blockage inside. The existing pipe connection is to screw the threaded sleeve on the outside of the pipe to the outer wall of another pipe, but the rotation of the threaded pipe will also drive the pipe to rotate, causing the rubber ring at the end of the pipe to rotate and tighten the seal, which can easily cause wrinkles on the rubber ring, affecting the sealing effect and causing serious wear on the rubber ring. In addition, when the rubber ring rotates and the pipe contacts the connection, the friction of the rubber is also large, making it inconvenient to connect. For this reason, we propose a water conservancy pipe that is easy to connect. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0018] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present patent provides a technical solution: a water conservancy pipeline that is easy to connect, comprising a first pipeline 1 and a second pipeline 4, a circular groove 2 is provided at the right end of the inner wall of the first pipeline 1, an external threaded ring 3 is integrally formed on the right side of the outer wall of the first pipeline 1, a pressure ring 5 is integrally formed at the left end of the second pipeline 4, a rubber ring is bonded to the left side of the pressure ring 5, the pressure ring 5 is located on the right side of the circular groove 2, the outer diameter of the pressure ring 5 matches the inner diameter of the circular groove 2, a mounting ring 6 is integrally formed on the outer wall of the second pipeline 4, an annular groove 7 is provided on the outer wall of the mounting ring 6, a circular ring 8 is rotatably connected in the circular groove 7, the shape and size of the circular ring 8 match the internal shape and size of the circular groove 7, a connecting ring 9 is fixedly installed on the outer wall of the circular ring 8, an internal threaded ring 10 is fixedly installed on the left end of the connecting ring 9, the inner wall of the internal threaded ring 10 is screwed on the outer wall of the external threaded ring 3, and limit members are provided on both the upper and lower ends of the left side of the mounting ring 6.

[0019] Specifically, the limiting part includes a sliding rod 11, the right end of which is integrally formed on the left side of the mounting ring 6, and limiting grooves 12 are provided at the upper and lower ends of the right side of the external threaded ring 3. The left end of the sliding rod 11 is inserted into the limiting groove 12, and the side wall of the sliding rod 11 and the inner wall of the limiting groove 12 slide relatively together.

[0020] The side wall of the slide rod 11 and the inner wall of the limiting slide groove 12 slide relative to each other to limit the movement trajectory of the mounting ring 6, the second pipe 4 and the pressing ring 5 so that they can only move left and right, so that the rubber ring on the left side of the pressing ring 5 is stably pressed in the circular groove 2.

[0021] Specifically, the left end of the slide rod 11 exceeds the left end surface of the internal thread ring 10 .

[0022] like Figure 2 As shown, by the left end of the slide rod 11 exceeding the left end surface of the internal thread ring 10, when the internal thread ring 10 is not screwed onto the external thread ring 3, the slide rod 11 will first be inserted into the limiting slide groove 12 to play a limiting role.

[0023] Specifically, the sliding rod 11 may be a cross rod.

[0024] For example, if the slide bar 11 is cylindrical, the side walls of the slide bar 11 will all be in contact with the inner walls of the limiting slide groove 12. When the slide bar 11 moves left and right, the friction force is relatively large. If the cross section of the slide bar 11 is set to a cross shape, the contact area can be greatly reduced, thereby reducing the friction resistance.

[0025] Specifically, the circular ring 8 includes a first half ring 13 and a second half ring 14 , the two ends of the first half ring 13 and the second half ring 14 are relatively close to each other, and an arc plate 15 is fixedly installed in the middle of the outer side walls of the first half ring 13 and the second half ring 14 , and the outer side wall of the arc plate 15 is attached to the inner side wall of the connecting ring 9 .

[0026] By dividing the circular ring 8 into the first half ring 13 and the second half ring 14, it is convenient to install the circular ring 8 in the annular groove 7 in the early stage, which facilitates the early assembly.

[0027] Specifically, a thread groove 16 is provided in the middle of the outer wall of the first half ring 13 and the second half ring 14, a first circular hole 17 is provided in the middle of the arc plate 15, and second circular holes 18 are provided at both ends of the connecting ring 9. Bolts 19 are provided in the second circular holes 18, and the inner ends of the bolts 19 pass through the first circular holes 17 and are screwed in the thread groove 16.

[0028] like Figure 3 As shown, by arranging the arc plate 15 between the first half ring 13, the second half ring 14 and the connecting ring 9, a gap can be created between the circular ring 8 and the connecting ring 9, thereby preventing the connecting ring 9 from contacting the outer wall of the mounting ring 6 and causing contact friction during rotation.

[0029] Specifically, a concave surface 20 is provided on the inner side of the end of the bolt 19 , and spherical surfaces 21 are integrally formed on both ends of the outer wall of the connecting ring 9 , and the concave surface 20 fits tightly on the spherical surface 21 .

[0030] If the spherical surface 21 does not exist, when the bolt 19 is locked, a small portion of the inner side of the end of the bolt 19 will be pressed against the outer wall of the connecting ring 9, and the locking force will be relatively small. If the concave surface 20 is tightly fitted on the spherical surface 21, the locking effect of the end of the bolt 19 on the connecting ring 9 can be greatly increased, indirectly increasing the connectivity between the first half ring 13 and the second half ring 14 and the connecting ring 9.

[0031] Working principle: Figure 1 , 2As shown, the internal threaded ring 10 can be screwed onto the external threaded ring 3 and moved to the left by rotating it. The internal threaded ring 10 drives the mounting ring 6 and the second pipe 4 to move to the left through the connecting ring 9 and the circular ring 8. Since the slide bar 11 slides in the limiting slide groove 12, the second pipe 4 can only move linearly to the left so that the rubber ring on the left side of the pressure ring 5 is pressed tightly in the circular groove 2, avoiding wrinkles and wear on the rubber ring, ensuring the connection sealing effect of the pipeline, and also avoiding the rotation and compression sealing of the rubber ring, which will greatly reduce the connection friction and facilitate the connection.
