Abstract
The utility model relates to a test pencil for magnetism, comprising a pencil cap, a pencil body, a bulb, a battery, a pressing spring, a probe and a magnetic loop. The probe, the pressing spring, the battery and the bulb are successively arranged in the pencil body. The utility model is used for the work which detects that whether a magnetic field exists or not, and in particular, the utility model is a simple and convenient test tool for the work of the maintenance of various devices using electromagnetic valves.
Description
The utility model is a kind of instrument of testing the solenoid valve on off operating mode.
Generally detect the solenoid valve on off operating mode, the electric wire of solenoid valve be disconnected, no-voltage be arranged, measure electromagnetic valve coil again and whether open circuit, thereby judge the on off operating mode of solenoid valve indirectly with the multimeter measurement.Measuring method trouble, equipment not directly perceived, that have do not allow to cut off electric wire, and the instantaneous working condition to solenoid valve is difficult for catching opportunity by the forelock.
Test pencil for magnetism of the present utility model is at above-mentioned shortcoming and needs, so that a kind of Test pencil for magnetism that simply, intuitively, fast, need not cut off electric wire to be provided.
The basic structure of the utility model Test pencil for magnetism is made up of the cap for brush (1), a body (2), bulb (3), battery (4), stage clip (5), probe (6), magnet ring (7) seven parts, it is characterized in that, pen is as cylindrical shape, and there is a clamp side, and the lower end nib partly is infundibulate; Cap for brush upper body is the boss cap that has cylindrical shape cap point; Lower body is a cylindrical shape, along cylinder outer surface the little fin of several circles is arranged, and by little fin a body and the cap for brush is closely cooperated; Probe is copper or aluminium matter cylinder, in adorn a highly sensitive dry-reed relay; Stage clip is a metal spring that has copper stage clip cap, and a contact of dry-reed relay is welded in the stage clip cap, and another contact of dry-reed relay is connected with bulb with an electric wire; Probe, stage clip, battery.Bulb is arranged in order from bottom to top in a body and is connected and forming circuit, compresses the cap for brush.Magnet ring is enclosed within on the boss of cap for brush upper body, between the magnet ring endoporus and the cap for brush, closely cooperates by cap for brush upper body cylindrical portions may one little fin.
Probe (6) can be made into all size according to designing requirement, and the specification of various probes is corresponding with magnetic field to be tested, and controls the circuit of back according to magnitude of field intensity.
Magnet ring (7) has and the corresponding field intensity of probe (6) test specification, is enclosed within when not using Test pencil for magnetism on the boss of cap for brush upper body, takes off before test, is placed on Test pencil for magnetism nib position, and whether verification once Test pencil for magnetism is effectively sensitive.
The cap for brush (1) is to be made by insulating material with a body (2), particularly forms with plastic injection-moulded.
When using this Test pencil for magnetism, as long as with the approaching tested solenoid valve of Test pencil for magnetism nib part, observe from the cylinder hole of cap for brush upper body then, as obstructed, bulb (3) does not work, and as switching on, bulb (3) is shinny, thereby reaches the purpose of measuring the solenoid valve on off operating mode.
Use this Test pencil for magnetism and carry out the test of solenoid valve on off operating mode,, also do not need to use the multimeter measuring voltage owing to do not need to cut off the electric wire of solenoid valve, method simply, directly perceived again rapidly.
The utility model can be widely used in the testing whether arbitrary magnetic field exists, and particularly in the maintenance of equipment work of various use solenoid valves, becomes simply again testing tool easily.
Accompanying drawing 1:
(1)-cap for brush; (2)-body; (3)-bulb; (4)-battery; (5)-stage clip; (6) probe; (7)-magnet ring.
Claims (2)
1, a kind of Test pencil for magnetism, its basic structure is made up of the cap for brush, a body, bulb, battery, stage clip, probe, magnet ring seven parts, it is characterized in that, and pen has a clamp as cylindrical shape, side, and the lower end nib partly is infundibulate; Cap for brush upper body is the boss cap that has cylindrical shape cap point, and lower body is a cylindrical shape, along cylinder outer surface the little fin of several circles is arranged, and by little fin a body and the cap for brush is closely cooperated; Probe is copper or aluminium matter cylinder, in adorn a highly sensitive dry-reed relay; Stage clip is a metal spring that has copper stage clip cap, and a contact of dry-reed relay is welded in the stage clip cap, and another contact of dry-reed relay is connected with bulb with an electric wire; Probe, stage clip, battery, bulb are arranged in order from bottom to top in a body and are connected and forming circuit, compress the cap for brush.Magnet ring is enclosed within on the boss of cap for brush upper body, and the magnet ring endoporus and the cap for brush closely cooperate by cap for brush upper body cylindrical portions may one little fin.
2,, it is characterized in that a body, the cap for brush make with insulating material according to the described Test pencil for magnetism of claim 1.
