Universal chassis for instrumentation

Abstract

The invention relates to a general-purpose case for instruments and meters. The upper and lower ends of the front and rear columns are respectively plugged into the upper and lower wrap angles of the front and rear columns, and the left and right ends of the front and rear transverse ribs are respectively plugged into the left and right sides of the front and rear frames. Inside the wrap angle, the front and rear ends of the left and right ribs are respectively plugged into the left and right wrap angles of the front and rear frames, and the upper and lower side plates are respectively embedded in the grooves on the upper and lower outer sides of the tie bars. All columns and cross bars are profiles of the same specification. All side reinforcements are profiles of the same specification and model. The left and right tie bars are profiles of the same specification and model. The upper and lower corners of the front frame are the same in structure and size as the upper and lower corners of the rear frame. A nut is respectively buried on the two inner walls, and a through hole is arranged at the back. The outer sides of the left and right tie bars are provided with grooves for inserting the side plates, and the upper and lower ends of the inner sides are also provided with grooves for fixing the bottom plate.

Description

technical field [0001] The invention relates to the field of general instrumentation cabinets, in particular to a general instrumentation cabinet with extruded profiles as the main material. Background technique [0002] As a protection device for internal instruments and meters, the chassis plays the role of protecting, supporting, fixing, and anti-interference for instruments and meters. It is an indispensable part of instruments and meters and is widely used in electromechanical and other fields, especially for Convenient case. Commonly used standard cabinets are manufactured by methods such as aluminum alloy extruded profiles, aluminum die-casting, injection molding, aluminum profile enclosures, and composite profiles. The widely used chassis are mostly structures with fixed shapes and sizes, and are installed in the chassis by screw connections after the instrumentation is debugged. Although these solutions solve the technical problems of instrumentation protection, i...

AI Technical Summary

Problems solved by technology

Although these solutions solve the technical problems of instrumentation protection, in actual use, with the development of instrumentation, there are higher requirements for the chassis

Especially when the instrumentation deviates greatly from the shape of the existing chassis, it causes a lot of inconvenience

Most of the chassis varieties are monotonous, and the material structure of the chassis is not reasonable, resulting in high production costs, long trial production cycle, and the overall size and shape are not easy to change.
