Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a handheld pipeline diameter measuring device. Background Art

[0002] Pipe diameter measurement is an important part of pipeline installation and maintenance. In the pipeline design stage, correct measurement of pipeline diameter can ensure that the pipeline system can meet the required flow and pressure requirements and reduce energy loss. In the pipeline installation and maintenance process, accurate diameter measurement can help select appropriate pipe fittings and connection methods to ensure the tightness and stability of the pipeline.

[0003] In the process of measuring the diameter of a pipeline, a handheld pipeline diameter measuring device is usually used to measure the diameter of the pipeline. In the process of using the handheld pipeline diameter measuring device, the operator needs to push the measuring plate upward to increase the distance between the measuring plate and the mounting seat, and then the mounting seat contacts the lower side of the outer arc surface of the tested pipeline. After that, the operator presses the measuring plate to reduce the distance between the measuring plate and the mounting seat, so that the measuring plate contacts the upper side of the outer arc surface of the tested pipeline. At this time, the value indicated by the measuring plate on the measuring ruler is the diameter of the tested pipeline, thereby realizing the diameter measurement of the pipeline;

[0004] Although the existing handheld pipeline diameter measuring device can measure the diameter of the pipeline, due to the fixed structure of the handheld pipeline diameter measuring device itself, it occupies a large area when not in use and is not convenient for storage. Some handheld pipeline diameter measuring devices use electronic devices such as laser measuring instruments to measure their diameters. Although this type of equipment occupies a small area and is easy to store and carry, the cost is relatively high. For this reason, we propose a handheld pipeline diameter measuring device.
