Description
Technical field
It the utility model is related to a kind of teaching mode for being used to measure resistance sizes.
Background technology
At present in teaching mode, be mostly to solid matter as measured object, due to the more difficult measurement of liquid,
So few resistance values to liquid measure, also lack the teaching mould of corresponding measurement liquid resistance size
Type so that teaching efficiency is made a discount.
Utility model content
The utility model provides a kind of teaching mode for being used to measure liquid resistance size, it is intended to solves existing teaching
The problem of model measurement liquid resistance is relatively difficult.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions：
A kind of teaching mode for being used to measure liquid resistance size, including testing resistance, resistance mounting seat, ammeter, guarantor
Protect resistance, power supply and wire；Resistance mounting seat, ammeter, protective resistance and the power supply pass sequentially through wired in series；It is described to treat
Measuring resistance is arranged in resistance mounting seat；The testing resistance is by insulation outer tube, sealing-plug, conductive plate and is filled in insulation outer tube
Interior testing liquid is formed, and the one end for the outer tube that insulate is closed by conductive plate and the other end is closed by sealing-plug, and sealing-plug is provided with
Conducting block inside and outside connection insulation outer tube.
Further, an insulating inner tube is plugged with the insulation outer tube, insulating inner tube one end is sealingly fixed to conduction
On plate and the insulating inner tube other end is sealed by sealing-plug.Liquid filling body in inner tube can be intended to, with outer tube fill when area
Difference, measured by changing the liquid of testing resistance.
Further, sealing-plug is tightly connected by screw thread and insulation outer tube.
Further, the sealing-plug is tightly connected by taper thread and insulation outer tube.Good sealing effect.
Further, the resistance mounting seat is separately positioned on pedestal both ends by the pedestal and two for installing testing resistance
Conducting strip form.
Compared with prior art the utility model has the advantages that：
By the way that testing liquid is placed in insulation tube in the utility model, carry out shape and fix, then measure electricity
Resistance, measurement liquid resistance is more convenient, can be put into different liquid as needed.In addition, set conductive plate and conducting block can
To ensure that liquid accesses whole circuit system.

Refering to Fig. 1 and Fig. 2, a kind of teaching mode for being used to measure liquid resistance size, including the installation of testing resistance, resistance
Seat 1, ammeter 2, protective resistance 4, power supply 5 and wire 6；Resistance mounting seat, ammeter, protective resistance and the power supply lead to successively
Cross wired in series；The testing resistance is arranged in resistance mounting seat；The testing resistance by insulation outer tube 7, sealing-plug 8, lead
Electroplax 9 and the testing liquid being filled in insulation outer tube are formed, and the one end for the outer tube that insulate is closed by conductive plate and the other end is close
Blocking is closed, the conducting block 10 being communicated with sealing-plug inside and outside insulation outer tube.
An insulating inner tube 3 is plugged with insulation outer tube, insulating inner tube one end is sealingly fixed on conductive plate and insulated
The inner tube other end is sealed by sealing-plug.
Sealing-plug is tightly connected by screw thread and insulation outer tube.The sealing-plug is connected by taper thread and the outer seal of tube that insulate
Connect.
The conducting strip structure that resistance mounting seat is separately positioned on pedestal both ends by the pedestal and two for installing testing resistance
Into.
By filling and treating to insulating inner tube, insulation outer tube or simultaneously into insulating inner tube and insulation outer tube in the utility model
Liquid is surveyed, is then sealed with sealing-plug, to be measured to the resistance of testing liquid.
Specific embodiment of the utility model is the foregoing is only, but the technical characteristics of the utility model is not limited to
This, any those skilled in the art in field of the present utility model, all cover in this practicality newly by the change or modification made
Among the scope of the claims of type.
