Description

Technical Field

[0001] The present application relates to the technical field of water supply and drainage, and more specifically, to a water conservancy pipeline that is easy to connect and install. Background Art

[0002] The current construction of sewage pipes is to transfer the pipes produced in the factory one by one to the construction site and bury them in the corresponding positions. In order to ensure the stability and smoothness of long-distance pipelines, each section of the pipeline needs to be docked with each other to stabilize it so that it will not leak or come off. At present, there is a Chinese patent on the market (Announcement No. CN202301328U discloses a plastic pipe with a seamless joint), which includes a pipe body, and bell mouths are provided at both ends of the pipe body. Flanges are provided on the outside of the bell mouth, and the pipe bodies that are docked with each other can be connected by flanges. However, under this structure, the structure of the pipe body needs to be double-layered, and the structure is relatively complex, and the contact surface is prone to deformation.

[0003] The document with the prior art publication number CN208417868U provides a pipe that is easy to dock. The device applies the holding force directly to the flared part with a larger thickness. The flared part structure provided in one piece ensures that the clamping force of the flange can be directly transmitted to the end face. At the same time, the force application surface is also an inclined surface structure. In this way, the force application part structure of the flange is relatively thick and can maintain high stability. It can ensure that the force in the flared part is evenly dispersed and reduce abnormal deformation on the flared part. The entire structure can be directly processed and formed, with high processing efficiency and low cost.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the pipeline is butt-jointed, multiple bolt and nut groups need to be rotated and matched one by one to complete the butt-jointing of the pipeline, which is inconvenient to disassemble and assemble.

[0005] With respect to the above-mentioned related technologies, the inventor believes that when the pipes are butt-jointed, multiple bolt and nut groups need to be rotated and matched one by one to complete the butt-jointing of the pipes, which makes disassembly and assembly inconvenient.

[0006] In view of this, we propose a water conservancy pipeline which is easy to connect and install. Utility Model Content

[0009] 2. Technical solution

[0010] The technical solution of the present application provides a water conservancy pipeline that is easy to connect and install, including: a pipe body, a first flange is integrally formed at one end of the pipe body, and a second flange is integrally formed at the other end, a plurality of annularly distributed clips are fixedly installed on the first flange, and the clips can be clipped on the second flange, and a fixing sleeve is detachably connected to the pipe body, the fixing sleeve is close to the first flange to seal the gap, and the fixing sleeve is close to the second flange to push the plurality of clips to expand outward.

[0011] By adopting the above technical solution, the first flange and the second flange of the two tube bodies are brought close to each other, and the multiple buckle claws on the first flange are buckled on the second flange, so that the installation between the two tube bodies can be completed. Then, the fixing sleeve is rotated so that the fixing sleeve is arranged on the first flange and the second flange. First, the buckle is prevented from being separated from the second flange, and second, the gap between the first flange and the second flange is sealed. When disassembling, the fixing sleeve is removed, and then the fixing sleeve on the front tube body is moved in the direction of the buckle, and the multiple buckles are squeezed to expand outward at the same time to be separated from the second flange. At this time, the two tube bodies can be separated.

[0012] As an optional solution to the technical solution of the present application document, a plurality of annularly distributed grooves adapted to the buckle are provided on the second flange.

[0013] By adopting the above technical solution, each buckle is matched with the corresponding buckle slot so as to position the buckle and avoid reverse rotation between two interconnected tube bodies.

[0014] As an optional solution of the technical solution of the present application document, the first flange is radially provided with an annular groove, and the second flange is integrally formed with an annular tube adapted to the annular groove.

[0015] By adopting the above technical solution, the annular tube at the second flange end is inserted into the annular groove at the rear, so that the cooperation between the annular tube and the annular groove can improve the sealing between the two tube bodies and the connection strength between the two tube bodies.

[0016] As an optional solution of the technical solution of the present application document, the fixing sleeve includes a ring and an internally threaded tube integrally formed with the ring, the inner diameter of the ring is adapted to the outer diameters of the first flange and the second flange, the side of the internally threaded tube close to the second flange is a slope structure, the side of the buckle close to the internally threaded tube is a slope structure, and the two ends of the tube body are respectively provided with a first thread and a second thread adapted to the internally threaded tube.

[0017] By adopting the above technical solution, the first thread is close to the first flange, and the second thread is close to the second flange. After the two tube bodies are connected, the internal threaded tube on the rear tube body is rotated so that the internal threaded tube is connected to the first threaded thread, and the first flange and the second flange are sleeved in the ring. At this time, the ring is used to avoid the buckle from turning outward, and the connection between the first flange and the second flange can be sealed. When disassembling, the rear internal threaded tube is adjusted to the right, and then the front internal threaded tube is moved to the right and connected to the front second threaded thread. At this time, the slope on the right side of the internal threaded tube contacts the slope of the buckle, causing the buckle to expand outward, so that multiple buckles are detached from the second flange at the same time.

[0018] As an optional solution of the technical solution of this application document, a plurality of sealing rings are embedded in the ring.

[0019] By adopting the above technical solution, after the collar is sleeved around the first flange and the second flange, the sealing performance of the collar after being connected to the pipe body can be improved under the action of multiple sealing rings.
