The fixed plate that one group and rotating shaft are adapted is provided with, fixed front edge of board is provided with the resigning being adapted with liquid level sensor pivoted arm and lacks
Mouthful, fixed plate leading section is additionally provided with one group of screw hole.
In order to realize that the liquid level sensor in three fixed plates is non-interference when pivoted arm long duration test is done, rotating shaft is three sections
Formula rotating shaft, connects including left rotary shaft, right spindle and intermediate rotary shaft, the side wall of intermediate rotary shaft and left rotary shaft, the side wall of right spindle；Left
Rotating shaft and right spindle are coaxially disposed；Fixed plate corresponding left rotary shaft, right spindle and intermediate rotary shaft are provided with three pieces altogether.
For the ease of controlling the rotating speed and revolution of rotating shaft, on cabinet, be provided with counter and speed-regulating switch, speed-regulating switch and
Motor is connected, and is provided with the proximity switch being connected with counter on motor.
The beneficial effects of the utility model：Liquid level sensor pivoted arm to be detected is fixed in fixed plate, by driving electricity
The rotation of machine drives the rotation of rotating shaft, so as to drive the float movement on pivoted arm, and then realizes the durable test of rotating shaft, whole fills
Simple structure is put, dependable performance is easy to operate, it is easy to accomplish.
Below with reference to drawings and Examples, the utility model is described in detail.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Structural representations of the Fig. 2 for liquid level sensor.
Specific embodiment
Embodiment, the basic structure of existing liquid level sensor as described in Figure 2, including mounting bracket 31, are arranged on installation
Wire resistor board mount 32 on support 31, the wire resistor plate 33 being arranged on wire resistor board mount 32, is arranged on coiling
The brushing piece 34 being adapted with wire resistor plate 33 on resistor plate support 32, is additionally provided with pivoted arm 35 on wire resistor board mount 32,
The end of pivoted arm 35 arranges float 36；Protective cover 37 is enclosed with wire resistor board mount 32,37 back side front and back end of protective cover
Raised 38 are each side arranged.
A kind of the technical solution of the utility model liquid level sensor pivoted arm durability test apparatus as shown in Figure 1, including cabinet 1
With the test flume 2 being arranged on the right side of cabinet 1, motor is provided with cabinet 1, is provided with and liquid level sensor in test flume 2
The rotating shaft that float on pivoted arm is adapted, and connects with motor by one section of rotating shaft, is provided with one in 2 rear side sidewall of test flume
The fixed plate 6 that group and rotating shaft are adapted, 6 front end of fixed plate are provided with the resigning breach 7 being adapted with liquid level sensor pivoted arm 35,
6 leading section of fixed plate is additionally provided with one group of screw hole 8.Counter 9 and speed-regulating switch 10, speed-regulating switch 10 is provided with cabinet 1
It is connected with motor, on motor, is provided with the proximity switch being connected with counter 9.Rotating shaft and the float of liquid level sensor
36 are adapted.
Rotating shaft is three-segment type rotating shaft, including left rotary shaft 3, right spindle 4 and intermediate rotary shaft 5, the side wall of intermediate rotary shaft 5 and left-hand rotation
Axle 3, the side wall of right spindle 4 connect；Left rotary shaft 3 and right spindle 4 are coaxially disposed；The corresponding left rotary shaft 3 of fixed plate 6, right spindle 4 and in
Between rotating shaft 5 be provided with three pieces altogether.
Principle explanation：In work, the housing of liquid level sensor is fixed by screws on screw hole, resigning breach is played
To the effect that pivoted arm is stepped down, rotating shaft is used for fixed adaptation float.The rotation of rotating shaft drives the rotation of pivoted arm, and then realizes that pivoted arm is resistance to
The test of performance long.Three-segment type rotating shaft, the pivoted arm and float of the two neighboring liquid level sensor that effectively can stagger so that test
When, will not interact, and then improve the preparatory and testing efficiency of test.
The utility model is exemplarily described above in association with accompanying drawing.Obviously, the utility model is implemented not
Limited by aforesaid way.As long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or not improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasions, at this
Within the protection domain of utility model.
