Document Type and Number:
WIPO Patent Application WO/2023/284175
Kind Code:
A1
Abstract:
The present invention relates to the waveform recorder-related technical field. Disclosed are a waveform recorder having a dustproof function and a use method therefor. The waveform recorder comprises a recorder housing; keys are provided on one side of the recorder housing; heat dissipation holes are formed on each side wall of the recorder housing; a recess is formed on each outer side wall of the recorder housing; the heat dissipation holes are located on the inner wall of the recess; a dustproof plate matching the recess is rotatably provided on each outer side wall of the recorder housing; a supporting device capable of supporting the dustproof plate is provided on the inner wall of the dustproof plate; the supporting device comprises a supporting rod; the supporting rod is rotatably mounted on the inner wall of the dustproof plate; a sliding groove is formed on the inner wall of the recess; a sliding block matching the sliding groove is rotatably provided on one end of the supporting rod; a snap-fit plate matching the sliding block is provided at the bottom end of the recess; a protection device is provided on the outer side wall of the recorder housing at a position above the keys; the protection device comprises a rotating shaft; and a dustproof film is wound on the outer side wall of the rotating shaft. The dustproof plate can perform dustproof protection on the heat dissipation holes without hindering the heat dissipation of the heat dissipation holes, thereby improving the service life of the waveform recorder.
