Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a connecting piece for a fluid pipeline. Background Art

[0002] A pipeline is a channel for transporting liquids. According to the arrangement of its pipes, it can be divided into simple pipelines, parallel pipelines and branch pipelines. Parallel pipelines and branch pipelines are collectively called complex pipelines. Their concepts and characteristics are introduced as follows. A simple pipeline is a pipeline without branches, which can be divided into simple pipelines of equal diameter and series pipelines of variable diameter.

[0003] However, the connectors for fluid pipelines in the prior art still have the disadvantage that it is difficult to improve the tightness of the connectors during operation. When in use, after the connectors connect the pipelines, water tends to flow out from the side gaps when passing through, resulting in poor tightness of the connectors, which is not conducive to normal use. Moreover, the connectors for fluid pipelines in the prior art still have the disadvantage that it is difficult to effectively buffer the operation of the connectors. When in use, the connectors shake during operation, which makes the connectors easily damaged, resulting in a reduced service life. Utility Model Content

[0004] The purpose of the utility model is to provide a connector for a fluid pipeline to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The outer surface of the first connecting pipe is clamped with a pipeline connector, and the outer surface of the pipeline connector is clamped with a buffer assembly, and the buffer assembly includes a buffer plate, a spring and a limit ring. One side of the buffer plate is clamped with the outer surface of the pipeline connector, and the other side of the buffer plate is fixedly connected with the spring, and one side of the spring is fixedly connected with the limit ring;

[0010] Preferably, the buffer assembly further comprises a limiting screw, a threaded hole is provided inside the limiting ring, and the internal thread of the threaded hole is connected to the limiting screw.

[0011] Preferably, the first anti-slip assembly includes a first support rod, a first clamping block and a first column, the bottom of the first support rod is fixedly connected to the outer surface of the first connecting tube, one side of the first support rod is fixedly connected to the first clamping block, and the outer surface of the first clamping block is clamped with the first column.

[0012] Preferably, the connecting assembly includes a second extension tube and a second sealing ring, one side of the second extension tube is fixedly connected to one side of the second connecting tube, and the other side of the second extension tube is fixedly connected to the second sealing ring.

[0013] Preferably, the second anti-slip assembly includes a second support rod, a second clamping block and a second column, the bottom of the second support rod is fixedly connected to the outer surface of the second connecting tube, one side of the second support rod is fixedly connected to the second clamping block, and the outer surface of the second clamping block is clamped with the second column.

[0014] Preferably, a rectangular slot is formed on the outer surface of the pipe connector, and a handle is fixedly connected to the inside of the rectangular slot.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. This kind of fluid pipeline connector is provided with a first extension tube, a first sealing ring and a slot. When in use, the first extension tube is inserted into the connector. The area of ​​the first extension tube is smaller than that of the connecting tube, so the connecting tube and the connector can be smoothly aligned. After insertion, the first sealing ring will be stuck in the slot to prevent water from flowing out from the side. Then, the first connecting tube, the pipeline connector, the first extension tube, the first sealing ring and the slot are used in coordination, so as to achieve the effect of improving the tightness of the connector, and avoid the situation that after the connector connects the pipeline, water flows out from the side gap when passing through, which leads to poor tightness of the connector and is not conducive to normal use.

[0017] 2. This kind of fluid pipeline connector is provided with a buffer plate, a spring and a limit ring. When in use, the limit ring is placed around the outer surface of the connector. If the connector shakes during operation, it will collide with the buffer plate, and the buffer plate moves toward the side of the limit ring, driving the spring to contract inward, and then the spring rebounds and resets, which can reduce the vibration force. The pipeline connector, buffer plate, spring, limit ring and limit screw are used in coordination to achieve the effect of effective buffering during operation of the connector, thereby avoiding shaking of the connector during operation, which in turn makes the connector susceptible to damage and reduces its service life.
