Background
The instruments and meters are instruments or devices for detecting, measuring, observing and calculating various physical quantities, substance components, physical parameters and the like, such as vacuum leak detectors, pressure gauges, length meters, microscopes, multipliers, flow meters and the like, and belong to the instruments and meters.
The instrument part is a key structure for displaying detection parameters, the instrument is generally composed of a shell structure and an inner core structure, the inner core structure covers a display unit for displaying detection data and other units required for detection, the units are integrally installed inside the shell structure, and in order to facilitate the installation of the inner core, the shell is generally assembled by two or more structures, such as a metal lower shell for installing the inner core and a metal upper cover structure installed at the end part of the metal lower shell, so that a sealed shell structure is formed together to effectively protect the inner core.
In the production process of the instrument, the inner core is required to be assembled into the metal lower shell, then the metal upper cover is assembled onto the metal lower shell to complete the assembly processing of the shell, and in order to facilitate the installation of the metal upper cover and the later disassembly and maintenance, the metal upper cover and the metal lower shell are required to be assembled in a sleeving manner, namely, in the processing process, after the metal upper cover is aligned with the metal lower shell, the metal upper cover is pushed to the metal lower shell by utilizing the pushing structure, so that the metal upper cover is sleeved outside the metal lower shell, and the metal upper cover and the metal lower shell can be in transition fit or interference fit, so that the metal upper cover is stably installed on the metal lower shell.
