Dust-proof device for instruments

Abstract

The invention discloses a dust-proof device for instruments, and belongs to the technical field of transport. The dust-proof device comprises a dust-proof bottom plate, mounting plates and a dust-proof cover, wherein the mounting plates are integrally molded at the two ends of the dust-proof bottom plate, and the dust-proof cover is located above the dust-proof bottom plate; a rotating rod penetrates through one side of the dust-proof bottom plate, and is arranged in the dust-proof bottom plate through a bearing; one end, away from the dust-proof bottom plate, of the rotating rod is provided with a first connecting piece through the bearing; a mounting hole is formed in the first connecting piece; a connecting pillar is fixedly connected with the interior of the mounting hole; a second connecting piece is arranged at one end of the connecting pillar in an integrally molded manner; and one end, away from the first connecting piece, of the second connecting piece is connected onto the dust-proof cover. According to the dust-proof device, with the snap cooperation of snap frames and snap hooks, the dust-proof cover is opened and closed, and thereby, later maintenance of the instruments is facilitated.

Description

technical field [0001] The invention relates to the field of dust-proof technology, in particular to a dust-proof device for instruments and meters. Background technique [0002] In the current industrial development, instruments and meters have become an indispensable part of industrial production, and are also an important reminder of the safety of the production process. With the development of modern technology, instruments and meters are becoming more and more sophisticated. During use, dust particles in the air enter its interior, and a sealed dust-proof device is installed outside the general instrument to protect it. [0003] In the prior art, a sealed protective cover is generally used, and it is fixedly installed on the outside of the instrument to prevent dust. However, the sealed cover is generally fixed and installed, which makes it inconvenient to take the instrument. When a fault needs to be repaired, the sealing cover needs to be opened from the outside of t...

[0003] In the prior art, a sealed protective cover is generally used, and it is fixedly installed on the outside of the instrument to prevent dust. However, the sealed cover is generally fixed and installed, which makes it inconvenient to take the instrument. When a fault needs to be repaired, it is necessary to open the sealing cover from the outside of the instrument to maintain the instrument. Therefore, the present invention proposes a dust-proof device for the instrument
