Description

Technical Field

[0001] The invention relates to the technical field of mounting and connecting structures, and in particular to a mounting and connecting structure of a depth sounder. Background Art

[0002] The depth sounder is a new generation of fully digital and computerized product with dustproof, waterproof and earthquake-resistant functions. It is a measuring device that integrates water depth measurement, software graphic navigation, positioning data, and water depth data collection functions. It is an ideal equipment for ocean, river, lake, land depth measurement and mining, port, and waterway dredging engineering measurement. The depth sounder usually needs to be installed and used with a bracket. When the depth sounder needs to be installed on the bracket for assembly, it needs to be realized with the help of a connecting installation structure.

At this time, since the operating end surface of the depth sounder is covered, when someone wants to turn it over for use, it is first necessary to move the lifting plate to the lower end. However, since the control rod is locked by the lifting block, which is not known to outsiders, the lifting plate cannot be moved to the lower end, and thus the depth sounder cannot be stolen or data stolen.
