Liquid pressure calibration device and its main body

Abstract

1. The name of the product of this design: Liquid pressure calibration device and its main body. 2. Purpose of the product of this design: Both the overall and local uses are used to verify, calibrate and check pressure instruments using liquid media. 3. The key points of the design of this design product are: the key points of design 1 to design 3 are the local shapes for which protection is sought, and the key points of design 4 to design 6 are the shapes. 4. The picture or photo that best illustrates the key points of the design: Design 1 Stereoscopic drawing 1. 5. Designate Design 1 as the base design. 6. Other situations that need to be explained: The change state diagram of design 3 represents the schematic diagram of the instrument joint after rotation; the change state diagram of design 6 represents the schematic diagram of the instrument joint after rotation. 7. Other notes: Designs 1 to 3 request protection for partial appearance designs, where the solid line represents the part for which protection is requested, the dotted line represents the other parts, and the dot-dash line represents the dividing line between the part for which protection is requested and the other parts.
