Waterproof shell of micro-card self-control instrument

Abstract

The invention discloses a waterproof shell of a micro-card self-control instrument. The shell comprises a waterproof shell body, wherein an accommodating cavity is formed in the waterproof shell body;a clamping groove is formed in the inner surface of the accommodating cavity near the front end; a glass front cover is arranged in the clamping groove in an embedded manner; anti-falling rubber padsare fixedly mounted at four corners of the outer surface of the lower end of the waterproof shell body; an overhaul copper plate is fixedly mounted at the rear end of the waterproof shell body; and No.2 fixing bolts are arranged at four corners of the outer surface of the rear end of the overhaul copper plate. To sum up, the waterproof shell has the advantages that the waterproof cover, the anti-falling rubber pads and the overhaul copper plate are arranged on the waterproof shell of the micro-card self-control instrument, firstly, the blocking water effect can be played, and the waterproof effect is better; secondly, the anti-falling effect can be played, the possibility that the waterproof shell is broken is reduced; in addition, the thermal conductivity of the waterproof shell can be improved, the practicability is better, the structure is simple, and the use is facilitated.

Description

technical field [0001] The invention relates to the field of automatic control instruments, in particular to a waterproof case for micro-card automatic control instruments. Background technique [0002] The micro-card automatic control instrument waterproof case is a waterproof case used on the micro-card automatic control instrument. The self-control instrument is also called an automatic instrument. It is composed of several automatic components and has relatively complete functions. It generally has Several functions, such as measurement, display, recording or measurement, control, alarm, etc., the casing needs to have a certain waterproof performance; the current waterproof casing of the micro-card automatic control instrument has certain disadvantages in use. First, the existing waterproof casing adopts Separate sealing and waterproofing does not have the function of water shielding.

Problems solved by technology

[0002] The micro-card automatic control instrument waterproof case is a waterproof case used on the micro-card automatic control instrument. The self-control instrument is also called an automatic instrument. It is composed of several automatic components and has relatively complete functions. It generally has Several functions, such as measurement, display, recording or measurement, control, alarm, etc., the casing needs to have a certain waterproof performance; the current waterproof casing of the micro-card automatic control instrument has certain disadvantages in use. First, the existing waterproof casing adopts Separate sealing and waterproofing does not have the function of water shielding. Separate sealing and waterproofing will lead to water leakage and poor waterproof performance. Secondly, there is no anti-drop measure. Dropping measures can easily damage the internal components, easily cause the entire automatic control instrument to fail, resulting in unusability, low safety, and secondly, there are no good heat conduction measures. The access panel of the traditional waterproof shell back cover is made of plastic material, which does not have heat conduction Performance, can not reduce the temperature inside the waterproof case, the practicability is not good, for this reason, we design a micro-card automatic control instrument waterproof case
