Further, the fixing pipe is in threaded fit with the wall plate. Design like this makes fixed pipe more firm with wallboard complex, and then makes holistic installation more firm, is difficult for not hard up.
Further, the sensor body is in threaded fit with the slide tube. Therefore, the structure is simple, and the installation is stable.
Furthermore, a plurality of grooves which are distributed in a central symmetry mode are arranged on the outer sides of the end cover nut and the locking nut. The design is convenient for screwing and fixing operation.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the end cap nut of the present invention.
The sensor comprises a wall plate 1, a fixing pipe 2, a limiting retainer ring 2a, an end cover nut 3, a wire passing hole 3a, a locking nut 4, a sliding pipe 5, a sensor body 6, a connecting cable 6a, a supporting spring 7 and a groove 8.
Detailed Description
Example one
As shown in fig. 1-2, a liquid level sensor on an upper partition plate of a hydraulic bracket for filling paste, the upper partition plate comprises a wall plate 1; the method is characterized in that: the sensor comprises a fixed pipe 2, wherein the fixed pipe 2 is detachably arranged on a wallboard 1, and two ends of the fixed pipe 2 extend out of the wallboard 1; the outer side end of the fixed pipe 2 is provided with a limit retainer ring 2 a; the end cap nut 3, the above-mentioned end cap nut 3 is installed on inboard end of the fixed pipe 2 removably, and cooperate with thread of the fixed pipe 2; the middle part of the end cover nut 3 is provided with a wire passing hole 3 a; a locking nut 4, the locking nut 4 being detachably mounted on the outer end of the fixed pipe 2 and being screw-fitted to the fixed pipe 2; a slide pipe 5, the slide pipe 5 is movably arranged in the fixed pipe 2; a sensor body 6, wherein the sensor body 6 is detachably arranged in the slide pipe 5, and the measuring end of the sensor body 6 extends out of the slide pipe 5; the tail end of the sensor body 6 is provided with a connecting cable 6a, and the connecting cable 6a extends out of the wire passing hole 3; and the supporting spring 7 is arranged in the slide tube 5, one end of the supporting spring 7 abuts against the end cover nut 3, and the other end of the supporting spring abuts against the slide tube 5.
