Description
Technical field
The present invention relates to electric power tool field, specifically a kind of feeler lever of high voltage testing device.
Background technology
High voltage electroscope be on detection power circuit whether one of powered common tool, high voltage electroscope can be simply
The powered situation of circuit is judged, so in electric operating, it can be ensured that without electricity on the power circuit of operation, it is ensured that operator
The safety of member.
But, in practical work, touched because the general higher or staff of power circuit needs to be used in place farther out
Head goes to contact power circuit, and operating personnel cannot intuitively judge whether contact contacts with power circuit, in general, in order to
Ensure that contact is effectively contacted with power circuit, one end distance typically is moved into power circuit direction finding, but because contact is smaller,
A power circuit left side may be made to shake right rolling, the difficulty of measurement is increased on the contrary, while power circuit is rocked, also easily filled with high voltage testing
Other parts put come in contact, and may bring potential safety hazard.
Such as Chinese invention patent《A kind of high voltage testing device》（Application number 201410081045.6）Disclose a kind of high pressure
Electroscopic device, including handle and feeler lever in control box are connected to, feeler lever includes insulation tube and contact, is provided with insulation tube
The current rectifying and wave filtering circuit and a component piezoresistance electrically connected successively with contact, insulation tube wall are provided with one group of location hole；Control box
Retaining spring is inside provided with, insulation tube with the cooperation of location hole with control box is connected through control box and by retaining spring；Control
The four-operational amplifier that constant voltage dc source is powered is provided with box, four computings are constituted after one end series connection divider resistance of retaining spring
The positive pole input of amplifier, the output driving of four-operational amplifier is located at the light emitting diode of control box；Can by adjusting feeler lever
Change series connection divider resistance in circuit, four-operational amplifier is obtained different output voltages, sentenced by Light-Emitting Diode
Disconnected power circuit it is electric with three-phase equilibrium situation, to judging with the presence or absence of obvious three-phase imbalance on circuit, be beneficial to
Operating personnel's screening test, improves operating efficiency.But how the patent document does not ensure that feeler lever is good with power circuit also
Good contact proposes solution.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of feeler lever of high voltage testing device.Device of the invention leads to
The pressure change of the upper feeler lever of detection is crossed, to determine contact situation of the upper feeler lever with power circuit, is easy to operating personnel to operate, will not
There is the situation of operating process erroneous judgement.
The technical scheme is that：A kind of feeler lever of high voltage testing device, including upper feeler lever, carriage, elasticity dress
Put, pressure sensor, measurement apparatus, lower feeler lever, it is characterised in that：Pressure sensor and measurement are provided with described lower feeler lever
Device, elastic device is arranged between feeler lever and lower feeler lever, and spring is set in elastic device, and elastic device passes through carriage
It is connected with upper feeler lever, the spring of elastic device is connected with the pressure sensor of lower feeler lever, and measurement apparatus are connected with pressure sensor；
Described upper feeler lever is rounded nose or fork head.
According to the feeler lever of high voltage testing device as described above, it is characterised in that：Described pressure sensor should for resistance
Transformation force snesor.
According to the feeler lever of high voltage testing device as described above, it is characterised in that：Described measurement apparatus include power supply, inspection
Slowdown monitoring circuit, LED, detection circuit are connected with pressure sensor, power supply and LED respectively.
The beneficial effects of the invention are as follows：Operating personnel can confirm that whether high voltage testing device contacts with tested circuit,
Erroneous judgement situation will not occur；Make operating process simple and clear；The apparatus structure is simple, is easy to manufacture.

Specific embodiment
Technical scheme is described further below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the feeler lever of high voltage testing device of the invention includes upper feeler lever 1, carriage 2, elasticity dress
Put 3, pressure sensor 4, measurement apparatus 5, lower feeler lever 6.Pressure sensor 4 and measurement apparatus 5 are provided with lower feeler lever 6.Elasticity
Device 3 is arranged between feeler lever 1 and lower feeler lever 6, sets spring in elastic device 3, elastic device 3 by carriage 2 with
Upper feeler lever 1 is connected, and the spring of elastic device 3 is connected with the pressure sensor 4 of lower feeler lever 6, so after upper feeler lever 1 is pressurized, is led to
The slide downward of carriage 2 is crossed, pressure sensor 4 can be made to produce larger pressure, and then pressure is gathered by measurement apparatus 5
Change, and show, operating personnel is intuitively known very much contact feelings of the high voltage testing device with power circuit
Condition, as long as the lamp of measurement apparatus 5 is bright, now as high voltage testing device shows tested circuit without electricity, then operating personnel can be true
Now circuit and not charged is recognized, without being entangled with whether now high voltage testing device contacts with tested circuit.
Pressure sensor of the invention 4 can select resistance-strain pressure sensor, then pressure change can make pressure sensor 4
Resistance variations, so as to when resistance variations to a certain extent when, LED can then be lighted.
As shown in Figure 2 and Figure 4, measurement apparatus of the invention 5 include power supply 51, detection circuit 52, LED 53, detection electricity
Road 52 is connected with pressure sensor 4, power supply 51 and LED 53 respectively, can be using common battery as power supply 51, and pressure is passed
The resistance variations of sensor 4 are so that LED 53 is bright or go out.In Fig. 4, VCC is dc source, and RX is adjustable resistance, and R1 is pressure
The equivalent resistance of sensor 4, Q1 is triode, and D1 is LED.
As shown in Figure 1 and Figure 4, upper feeler lever 1 of the invention can use rounded nose or fork head, be carried out in the present invention using fork
Forming head, so after fork is stuck on tested circuit, then LED 53 is lighted, then be more prone to judge upper feeler lever 1 and be tested
The contact situation of circuit.
