Waterproof sealing structure of liquid level transmitter

Abstract

The invention relates to the technical field of liquid level transmitters and discloses a waterproof sealing structure of a liquid level transmitter. The waterproof sealing structure includes a housing, wherein the inner wall of the upper end of the shell is provided with a first thread and a second thread. The inner wall of the first thread is screwed with a glue-pouring pressing ring; the innerwall of the second thread is screwed with a pressing sleeve; a liquid level cable is inserted into the inner wall of the pressing sleeve; the sealing gasket is attached to the lower surface of the pressing sleeve, the baffle is attached to the lower surface of the sealing gasket, the upper surface of the glue pouring pressing ring is attached to the lower surface of the baffle, and glue pouring isattached to the inner wall of the glue pouring pressing ring. According to the invention, the problems that a liquid level cable and a transmitter are assembled and fixed and internal gaps of the cable cannot resist water are solved, and long-term extrusion deformation of cores and air ducts is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid level transmitters, in particular to a waterproof sealing structure of a liquid level transmitter. Background technique [0002] The current transmitter housing is assembled with the liquid level cable by extruding the gasket to deform. The advantage of this method is that it is easy to operate and the process is simple, but the deformation of the gasket cannot completely solve the problem of the filler and wire core inside the cable. There is a gap between them. In addition, the long-term extrusion and deformation of the cable will also cause the deformation of the inner core of the cable and the air guide tube. Therefore, a waterproof sealing structure of the liquid level transmitter is proposed to solve the above-mentioned problems. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof sealing structure of a liquid level transmitter to solve the pro...
