Abstract

The invention discloses an engineering machinery instrument casing which comprises a combined panel, a combined pressing plate and a combined rear casing. The combined pressing plate is arranged between the combined panel and the combined rear casing, and water-proof protruding ridges are arranged on the peripheries of two sides of the combined pressing plate. Water-proof grooves corresponding to the water-proof ridges are formed in a face where the combined panel is in contact with the combined pressing plate and a face where the combined rear casing is in contact with the combined pressing plate. Sealing rubber strips pressed by the water-proof ridges in a butting mode are arranged on the two water-proof grooves, and the combined panel and the combined pressing plate form fixed connection through connection and embedding of nuts through sunk screws. The combined rear casing and the combined panel form fixed connection through a hexagonal bolt arranged on the combined panel through a sunk screw in a connection mode and penetrating the combined pressing plate. The engineering machinery instrument casing is simple in structure, effectively solves the problem that a panel embedded with nuts on the periphery is easy to crack, guarantees protective level, and greatly reduces mold manufacturing difficulty and difficulty of material selection and follow-up process processing.

Description

technical field [0001] The invention relates to a display instrument, in particular to an engineering machinery instrument case applied to a monitoring display instrument. Background technique [0002] Most of the current liquid crystal monitoring and display instrument shells are composed of combined panels, combined pressure plates and combined back shells. In terms of structure, the panel and transparent plate are integrated. Nuts are embedded around the combined panel, and the combined back shell is directly screwed. Fixed way. The shell of this instrument structure, the existence of the transparent plate limits the material selection to be transparent, and the combined panel is processed after painting, which increases the process; and the embedded nuts around the combined panel are easy to crack, resulting in a high rate of waste products directly for the combined panel . Contents of the invention [0003] The technical problem to be solved by the present invention...
