Description

A kind of electric clearance and creepage distance test device of audio frequency apparatus
Technical field
The utility model is related to measure articles for use field, electric clearance and the creepage distance test of especially a kind of audio frequency apparatus Device.
Background technology
To all electric products, associated safety examination criteria IEC60335, IEC62115, GB4706 of international and national and GB19865 etc., which has in stringent electric clearance and creepage distance safety requirements, such as GB19865 electricity Toy Safety Standards, to be required " electric clearance of functional insulation and creepage distance are no less than 0.5mm in electronic game tool ".Currently, with most widely measure electricity The utensil of gas gap and creepage distance is gauge, is a kind of sheet type measurer for examining gap, also known as clearance ruler or thickness gage Deng the curvature and thickness that, the key technical indexes is gauge.Traditional gauge is all a straight thin slice or L-type thin slice pair Electric product carries out direct observational measurement.When in use, a data will once be recorded to this gauge by often measuring, then again The measurement of next size is carried out, efficiency is relatively low, if recorded again after measuring multiple sizes, often occurs forgeing data The case where.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of electric clearances of audio frequency apparatus and creepage distance to survey Trial assembly is set, and has a markd function, when use can measure multiple data after data are recorded again, can avoid data and lose Forget, improves measurement efficiency.
Technical solution adopted by the utility model to solve its technical problems is:It a kind of electric clearance of audio frequency apparatus and climbs Electrical distance test device, including handle and measurement piece,
Further include slide bar, one end of the slide bar is fixedly connected with handle, and the other end is connected by connecting rod with piece is measured, Multiple sliding blocks with sliding bar cooperation are provided on the slide bar, each sliding block is connected with mounting plate by link block, The both ends of the mounting plate are respectively arranged with positioning plate and marking plate, and the positioning plate is non magnetic plate, and marking plate is magnetic sheet, Described a side for measuring piece is provided with magnetic conductive board, and the magnetic conductive board is located at magnetic conductive board with the positioning plate and marking plate Two sides are simultaneously slidably matched with magnetic conductive board, and attract each other between magnetic conductive board and marking plate;Label is provided on the marking plate Needle.
Further, the handle is cylinder, and the measurement piece is installed on handle by screw.
Further, the slide bar is cylindrical bar.
Further, the thickness for measuring piece is 1mm.
The utility model has the beneficial effects that:When often measuring a size, sliding slider, sliding block drives positioning plate, label Plate and label needle movement, make label needle be moved at the corresponding scale of the size, then carry out the measurement of next size, and profit Corresponding scale is marked with other label needle, after measuring multiple sizes, reads the reading and record of each scale.Using this Device carries out test to the electric clearance and creepage distance of audio frequency apparatus and testing efficiency can be improved, while will not forget data.
Description of the drawings
Fig. 1 is the schematic front view of the utility model.
Fig. 2 is the schematic cross-sectional view of A-A in Fig. 1.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the electric clearance and creepage distance test device of a kind of audio frequency apparatus of the utility model, packet Include handle 1 and measure piece 2, handle 1 is measured piece 2 and is used stainless steel substrates using plastics, the materials such as metal, thickness 1mm, 2mm or Person 1.5mm etc. is carved with scale and reading in its side.Further include slide bar 3, slide bar 3 can be circular in cross-section or rectangle Plastic bar, metal rod etc., one end of slide bar 3 is fixedly connected with handle 1, and the other end passes through connecting rod 4 and measures 2 phase of piece Even, multiple sliding blocks 5 being slidably matched with slide bar 3 are provided on the slide bar 3, sliding block 5 can be cylindrical shape, can also be rectangular The bodily form, plastics, metal etc., which may be used, has the material of some strength.Each sliding block 5 is connected with installation by link block 6 Plate 7, sliding block 5, link block 6 and mounting plate 7 can ensure enough intensity by being integrally formed.The both ends of the mounting plate 7 It is respectively arranged with positioning plate 8 and marking plate 9, the positioning plate 8 is non magnetic plate, and marking plate 9 is magnetic sheet, the measurement piece 2 A side be provided with magnetic conductive board 10, the magnetic conductive board 10 is located at the two of magnetic conductive board 10 with the positioning plate 8 and marking plate 9 Side is simultaneously slidably matched with magnetic conductive board 10, and attracts each other between magnetic conductive board 10 and marking plate 9, by magnetic force to marking plate 9 into Row positioning, can prevent marking plate 9 from sliding automatically.Label needle 11 is provided on the marking plate 9.
When measurement, using 2 detected size of piece, such as the size of 20mm is measured, then sliding slider 5, sliding block 5 drive link block 6, mounting plate 7, positioning plate 8, marking plate 9 and label 11 synchronizing moving of needle, until label needle 11 is located at the scale that reading is 20mm Place, then measures next size, if the size of 30mm, needle 11 will be marked to slide at the scale that reading is 20mm. After measuring several times, each data are re-recorded, measurement efficiency can be improved.
Preferably, the handle 1 is cylinder, and the measurement piece 2 is installed on handle 1 by screw.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
