Description

Technical Field

[0001] The utility model relates to the technical field of vernier calipers, in particular to a combined vernier caliper. Background Art

[0002] The combination vernier caliper addresses the limitations of traditional vernier calipers when measuring specific objects. Traditional vernier calipers primarily consist of a main scale and a sliding vernier attached to it, used to measure length, inner and outer diameters, and depth. While this design is simple and easy to use, its application is limited when working with complex or irregularly shaped objects. Existing vernier calipers have shortcomings when measuring wall thickness, particularly when working with bottles or cans, where narrow openings or obstructions make direct measurement difficult. This limits the application and practicality of vernier calipers. To overcome these limitations, a new combination vernier caliper is needed that not only retains the basic functions of a traditional vernier caliper but also adds a mounting mechanism to accommodate diverse measurement needs. This new caliper is designed to improve measurement accuracy and operational flexibility while simplifying the user experience. By incorporating an adjustable hinged lever and clamping block, this combination vernier caliper can measure over obstructions, such as the mouth of a bottle or can. In addition, by setting positioning rods and other fixed structures, the stability and accuracy of the measurement are ensured, enabling the device to meet a wider range of application requirements.

[0003] Traditional vernier calipers are widely used in machining, manufacturing, and scientific research to measure dimensions such as the outer diameter, inner diameter, and depth of objects. However, traditional vernier calipers have certain limitations when measuring complex shapes or irregular surfaces, especially when high precision is required. They are difficult to meet the needs of modern industry and scientific research. Therefore, we propose a combined vernier caliper to solve this problem. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0012] In the utility model, the combined vernier caliper is configured to start a small motor fixedly installed in a fixed block at the top of a connecting block, so that the small motor drives a threaded rod fixedly installed at its output end to rotate.

By using multiple components in coordination, the measuring angle and position can be flexibly adjusted to achieve better measurement results.
