Protection device of electronic element measuring instrument

Abstract

The invention discloses a protection device of an electronic element measuring instrument. The protection device comprises a casing, wherein an installing plate is arranged at the bottom of the casing; first springs positioned on the casing are symmetrically arranged at the bottom end of the installing plate; installing strips are symmetrically arranged at the top end of the installing plate; symmetrical position limiting posts are arranged at the two ends of the installing plate in a penetrating way; the position limiting posts are fixed with the bottom end of the casing; connecting plates positioned at the two sides of the casing are arranged at the top end of the position limiting posts; an opening is formed in the middle part of the casing; the middle part of the opening is respectively provided with a wire inlet and a wire outlet; a first sealing strip is arranged at the top end of the opening; a second sealing strip is arranged at the bottom end of the opening; a rotating shaft connected with the casing is arranged at one end of the opening; an upper threaded half shaft is arranged at the top of one side, far away from the rotating shaft, of the opening; a lower threaded halfshaft is arranged at the bottom end of the upper threaded half shaft. The protection device has the beneficial effects that a protection device installing instrument is convenient; dust and moisturecan be effectively prevented from entering the instrument; the collision received in the use process can be buffered; the service life of the instrument is prolonged.

Description

technical field [0001] The invention relates to the field of electronic component measuring instruments, in particular to a protection device for electronic component measuring instruments. Background technique [0002] Electronic instruments refer to devices that detect, analyze, and test the performance, quality, and safety of electronic products. They can be roughly summarized into three major parts: electronic measuring instruments, electronic analysis instruments, and application instruments. There are optical electronic instruments, electronic component measuring instruments, and dynamic analysis instruments. And so on 24 subdivisions. With the continuous development of science and technology, the application range of electronic component measuring instruments is becoming wider and wider. The application environments of electronic component measuring instruments are different. Since electronic component measuring instruments are precision and sensitive parts, they ar...

Problems solved by technology

With the continuous development of science and technology, the application range of electronic component measuring instruments is becoming wider and wider. The application environments of electronic component measuring instruments are different. Since electronic component measuring instruments are precision and sensitive parts, they are easy to be used in poor environments. Moisture and various dusts enter the electronic instrument, which makes the electronic component measuring instrument unable to measure more accurate data, and the electronic component measuring instrument is vulnerable to collisions during use, resulting in damage to the electronic component measuring instrument, which reduces the use of the electronic component measuring instrument life
