Abstract:
A waterproof housing for an oscilloscope, comprising an upper cover (1), a base (8), and an annular plastic sealing ring (3). A hollow screw thread sleeve (6) extends integrally upwards on an upper end surface of the base (8). The upper cover (1) is covered on the upper end surface of the base (8), and is rotatably and insertedly connected to the outer wall of the hollow screw thread sleeve (6) by means of an internal screw thread. An annular limiting panel (9) extends integrally downwards on an edge side wall of a bottom end surface of the upper cover (1), and an annular limiting groove (10) positioned to an inner side of the annular limiting panel (9) is opened in an edge position of the bottom end surface of the upper cover (1). The annular plastic sealing ring (3) is positioned between the upper cover (1) and the base (8), and is matched with the inner cavity of the annular limiting groove (10) of the upper cover (1). A matching groove (7) is recessed integrally downwards on an edge side wall of a top end surface of the base (8), and the annular limiting panel (9) is matched with and insertedly connected to the inner cavity of the matching groove (7). The waterproof housing for an oscilloscope is able to improve the waterproof performance of the oscilloscope, and also does not impact use of the oscilloscope with externally connected cables.
