" 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.
