Abstract

The utility model provides a high protection grade guyed displacement sensor. A steel wire is winded on a first winding axle and is connected with a hook. A winding wheel assembly cover is fixed on the left side of a winding wheel assembly housing. A nest spring is disposed in a nest spring cover, and is sleeved on a second winding axle. The second winding axle is fixed on the winding wheel assembly cover, and enters the nest spring cover and a potentiometer housing. Two deep groove ball bearings are used to realize rotation among the second winding axle, the winding wheel assembly housing, and the nest spring cover. The input shaft of a potentiometer is connected with the second winding axle, and is fixed by a locking screw. The potentiometer is connected with a switching circuit board through a wire. The displacement sensor is advantaged in that the nest spring housing and the potentiometer housing are on a same side of the winding wheel assembly housing, and rubber washers are disposed among the winding wheel assembly housing, the nest spring housing, and the potentiometer housing, so leakproofness of the sensor is effectively enhanced, protection grade is improved. Under an extremely severe environment, the sensor can realize accurate measurement of displacement.

Embodiment
Provide preferred embodiment of the present utility model below, these embodiment unrestricted content of the present utility model.
Embodiment
The present embodiment is a kind of stay-supported type displacement sensor, as shown in Figure 1.Steel wire 15 is wrapped on the first winding wheel shaft 16, also the guide through hole 13 by reel assembly housing 22 upper ends is connected with hook 12, and reel assembly cover 19 is fixed on reel assembly housing 22 left sides.Nest spring cover 21 is arranged on reel assembly housing 22 right sides, between the two with rubber washer 14 sealings, and fixing with hexagon socket head cap screw 10.Nest spring 20 is positioned at nest spring cover 21, and is sleeved on the second winding wheel shaft 17, and its median fovea spring 20 one end are stuck in the draw-in groove 2 of the second winding wheel shaft 17.The second winding wheel shaft 17 is fixed on reel assembly housing 22, and be passed in nest spring cover 21 and potentiometer housing 4, use the first deep groove ball bearing 8 and the second deep groove ball bearing 18, realize the rotation between the second winding wheel shaft 17 and reel assembly housing 22, nest spring cover 21.Potentiometer 5 is positioned at potentiometer housing 4, and the input shaft of potentiometer 5 is connected with the second winding wheel shaft 17, and fixing with lock screw 7.Potentiometer 5 is connected with change-over circuit plate 3 by wire, and change-over circuit plate 3 is fixed on change-over circuit plate fixed mount 9, and the other end of change-over circuit plate fixed mount 9 is fixed on nest spring cover 21.Potentiometer housing 4 is fixed on the right side of nest spring cover 21, between the two with rubber washer 1 sealing, and fixing with cross flat head screw 11.Water joint 6 is fixed on potentiometer housing 4, and is connected with change-over circuit plate 3 by wire.
During use, first sensor is fixed, again hook 12 is connected with testee, along with the moving displacement of testee produces thereupon, hook 12 drives steel wire 15 to pull out from guide through hole 13, and steel wire 15 drives the first winding wheel shaft 16, the second winding wheel shaft 17 to rotate simultaneously, and two coiling arbor wheels pass to rotation input shaft and the nest spring 20 of potentiometer 5, potentiometer 5 input shafts rotate and cause that potentiometer 5 outputs signal to change-over circuit plate 3, and signal is exported by water joint 6 after treatment.After measurement completes, when measuring, the energy of laying in of nest spring 20 drives the second winding wheel shaft 17 reversions, thereby steel wire 15 is retracted and is again wrapped on the first winding wheel shaft 16, and hook 12 is got back to reference position.
