Abstract
A multifunctional test pencil comprises a test pencil body, wherein a finger contact and a voltage display screen are arranged on the test pencil body; one end of the test pencil body is connected with a probe which is connected with the voltage display screen; the voltage display screen is connected with the finger contact; the multifunctional test pencil is characterized in that the test pencil body is internally provided with a temperature measurement circuit; a digital temperature display screen is arranged on the front type face of the test pencil body; a clamp ring hoop is arranged on the back type face of the test pencil body; the clamp ring hoop is internally provided with a writing pencil; the probe is of a hollow cylindrical structure and is internally provided with a temperature sensor; and the temperature sensor is connected with the digital temperature display screen through the temperature measurement circuit. Compared with the prior art, the multifunctional test pencil has the advantages that the multifunctional test pencil has simple structure and low cost, is safe and convenient to use and operate, and can test temperature while measuring whether an electrical appliance is electrified or has electric leakage.
Description
Technical field
The utility model relates to a kind of test pencil, is specifically related to a kind of multifunction test pencil.
Background technology
The well staff is patrolled in electrician or oil field, all needs the electrical equipment in the work-yard is checked, the project of inspection mostly is the temperature of electric leakage situation and electrical work equipment.At present, existing product only is test pencil or thermometer and so on, and the staff need carry two kinds of instruments and enter work on the spot.Defective or deficiencies such as that this working method remains is many at the instrument that carries, operation inconvenience.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of multifunction test pencil simple in structure is provided.
Its technical scheme is: comprise the test pencil body, the test pencil body is provided with and refers to contact and voltage display screen, and the one end is connected with detecting head, and detecting head is connected with the voltage display screen, and the voltage display screen connects and refers to the contact.Described test pencil body interior is equipped with temperature measuring circuit, and its front space of a whole page is provided with the temperature digital display screen, and the back side space of a whole page is provided with the snap ring hoop, is placed with writing pen in this snap ring hoop; Described detecting head is the hollow cylindrical structure, and its inside is provided with temperature sensor, and described temperature sensor is connected with the temperature digital display screen by temperature measuring circuit.
Wherein, described temperature measuring circuit is the single-chip microcomputer temperature measurement circuit.
The utility model compared with prior art, have simple in structure, use easy-to-operate, with low cost and have when measuring the whether charged or electric leakage of electrical equipment again an advantage of probe temperature simultaneously.
Description of drawings
Fig. 1 is the Facad structure synoptic diagram of a kind of embodiment of the utility model;
Fig. 2 is the structure synoptic diagram of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1-Fig. 2, a kind of multifunction test pencil comprises test pencil body 1, and test pencil body 1 is provided with and refers to contact 3 and voltage display screen 4, and the one end is connected with detecting head 2, and detecting head 2 is connected with voltage display screen 4, and voltage display screen 4 connects and refers to contact 3.Described test pencil body 1 inside is equipped with temperature measuring circuit 6, and its front space of a whole page is provided with temperature digital display screen 5, and the back side space of a whole page is provided with snap ring hoop 9, is placed with writing pen 8 in this snap ring hoop 9; Described detecting head 2 is the hollow cylindrical structure, and its inside is provided with temperature sensor 7, and described temperature sensor 7 is connected with temperature digital display screen 5 by temperature measuring circuit 6.Wherein, described temperature measuring circuit 6 is the single-chip microcomputer temperature measurement circuit, and this circuit is the circuit that technician of the same trade knows altogether, and its principle is no longer narrated.
Whether charged when using or the electric leakage of certain equipment of this measurement device, the temperature signal that the temperature sensor 7 in the detecting head 2 is about to this equipment passes to temperature measuring circuit 6, is shown by temperature digital display screen 5 after treatment.The roughly the same common test pencil of demonstration of the whether charged or electric leakage of equipment.The writing pen of placing in the snap ring hoop 9 on test pencil body 1 back side space of a whole page 8 can make things convenient for record.
