Abstract
The utility model discloses an adjustable stay wire resistance-type displacement sensor which is composed of a stay wire, a wire winding box, a turning wheel, a spring, a rotating shaft, a cover plate, a stay wire end, a large gear, a potentiometer, a small gear and a potentiometer support. When the displacement sensor is used, movement of the a point under test drives the stay wire to move, and further drives the turning wheel to rotate; the turning wheel is connected with the potentiometer through the large gear and the small gear, transfers rotation quantity according to a certain proportion, and further converts the displacement of the point under test into electric signals; and when the displaying numerical value of the displacement of the point under test needs to be adjusted without changing the current length position of the stay wire, the required numerical value can be adjusted by rotating the large gear alone, thereby improving the controllability and the precision of the sensor.
Description
Technical field
The utility model belongs to the surveying instrument field, relates in particular to a kind of backguy resistance-type displacement transducer that is used for straight-line displacement or angle displacement measurement.
Background technology
Present backguy resistance sensor both domestic and external in use; When needs make the displacement data of its measurement show that numerical value changes; Can only change demonstration numerical value through regulating backguy length stroke, can not under the situation that does not change the existing travel position of backguy, regulate demonstration numerical value.When ship helm angular position is measured, after in a single day this type backguy sensor installs, show output not in needed position if find rudder angle, like the zero-bit adjustment, lean on when regulating the backguy stroke separately to meta, just can obtain zero-bit output, regulate quite bothering.
The utility model content
Above-mentioned deficiency to existing backguy resistance sensor; The applicant improves through research; A kind of adjustable type backguy resistance-type displacement transducer is provided; Can in use not change the existing length stroke of backguy and change displacement demonstration numerical value, improve the handling and accuracy of sensor through the resistance that changes potentiometer.
The technical scheme of the utility model is following:
A kind of adjustable type backguy resistance-type displacement transducer comprises backguy, winding box, runner, clockwork spring, rotation axis, cover plate, backguy termination, gear wheel, potentiometer, pinion wheel and potentiometer support; Rotation axis is fixed in the winding box, and on rotation axis, the bottom of runner is connected with cover plate to runner through Bearing Installation; Form cavity between cover plate, runner and the rotation axis; Clockwork spring is installed in the cavity, and an end of clockwork spring is fixed on the rotation axis, and the other end is fixed on the runner; One end of backguy is the backguy termination, and the backguy termination is fixed on the runner, and pull wire coil is on runner, and the other end of backguy stretches out winding box and links to each other with the measured point; Gear wheel passes through Bearing Installation on rotation axis, and contacts with runner through rubber band; The potentiometer support is fixed in the winding box, and potentiometer is installed on the potentiometer support, on the axle of potentiometer pinion wheel is installed, and gear wheel and pinion wheel are meshing with each other.
The useful technique effect of the utility model is:
The utlity model has characteristics such as degree of accuracy height, life-span length, handiness, when not changing the backguy extension position, can regulate, improved the handling and accuracy of sensor through rotating gear wheel when needs change measurement data demonstration numerical value.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1, the utility model comprises a winding box 2, and the center fixation of winding box 2 is equipped with rotation axis 5; Runner 3 passes through Bearing Installation on rotation axis 5; The bottom of runner 3 connects cover plate 6, between cover plate 6, runner 3 and rotation axis 5, forms cavity, and clockwork spring 4 is installed in this cavity; One end of this clockwork spring 4 is fixed on the rotation axis 5, and the other end is fixed on the runner 3 through screw rod.The backguy termination 7 of backguy 1 one ends is fixed on the runner 3, and the other end of backguy 1 after reeling on the runner 3 stretches out winding box 2 and link to each other with the measured point.Gear wheel 8 passes through another Bearing Installation on rotation axis 5, and is pressed on the runner 3 through the rubber band of its below.Also be installed with potentiometer support 11 in the winding box 2, on the potentiometer support 11 potentiometer be installed, on the axle of potentiometer 9 pinion wheel 10 is installed.Pinion wheel 10, gear wheel 8 are meshing with each other.
The principle of work of the utility model is following:
When the displacement of sensor measurement measured point, the measured point is moved drive backguy 1 and is moved, and then drives runner 3 rotations, and tightens up clockwork spring 4.Gear wheel 8 rotates with runner 3 through friction force synchronously, drives pinion wheel 10 rotations and potentiometer 9 rotations simultaneously.Potentiometer 9 is connected with runner 3 with gear wheel 8 through pinion wheel 10, and the transmission of the amount of being rotated by a certain percentage converts the displacement of measured point (being the displacement of backguy 1) into electric signal.Electric signal demonstrates measured point displacement numerical value through display device.
When not changing the existing extension position of backguy when in measuring process, need regulating the measured point displacement to show numerical value; Can rotate gear wheel 8 separately and be adjusted to needed setting numerical value; Rotation through gear wheel 8 changes the resistance value in the potentiometer 9, changes the purpose that shows numerical value thereby reach.Here, gear wheel 8 both can rotate with runner 3 synchronously, also can rotate separately.
When measuring end, only need take off the backguy 1 that is connected with the measured point, backguy 1 can automatically reset to reference position through the preset elastic force of clockwork spring 4, measures thereby carry out next time.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection domain of the utility model.
