Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection structure with adjustable length. Background Art

[0002] Hydraulic machinery is equipment and tools that work through fluid energy. It is commonly seen in heavy equipment. Hydraulic oil is transmitted to the actuator in the equipment at a very high pressure through a hydraulic pump. The pipe connections at special positions in the hydraulic system will use elbow head components that can adapt to the steering installation of the oil pipeline. In order to improve the adaptability of the elbow head components, an extension pipe is usually installed in the elbow head to increase the length of the elbow head joint, so that the elbow head with adjustable joint length can be connected to the pipe joint ends of different lengths.

[0003] When the actual elbow head component is connected to the pipe joint end through an extension pipe with adjustable length, the length of the extension pipe can be freely adjusted, which makes the sealing effect of the connection between the extension pipe and the pipe elbow poor, thereby causing the problem of oil leakage from the connection between the extension pipe and the pipe elbow, resulting in oil waste. Therefore, to address the above problem, we propose a pipe connection structure with adjustable length. Utility Model Content

[0004] The utility model aims to provide a pipe connection structure with adjustable length, so as to solve the problem that the length of the extension pipe can be freely adjusted, resulting in poor sealing effect at the connection between the extension pipe and the pipe elbow, which in turn causes oil leakage from the connection between the extension pipe and the pipe elbow, resulting in oil waste.

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