Description
Technical field
The utility model relates to electronic instrument technology field, particularly relates to a kind of teaching electrical pointer instrument.
Background technology
The electricity pointer instrument that school instruction is conventional comprises reometer, voltage table, and described reometer, voltage table are all converted by magneto-electric small range ammeter " gauge outfit ".Reometer common at present, the structure of voltage table comprise gauge outfit base and base plate, described gauge outfit base is provided with the cavity volume of a barreled, normally exist in described cavity volume, gauge outfit because of depot repair when misoperation is damaged cumbersome, instrument entirety also can be caused time serious to scrap.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, and the utility model provides a kind of teaching electrical pointer instrument and adopts gauge outfit and the split of gauge outfit base to arrange, and not only facilitates depot repair, also contributes to resource rational utilization.
For solving the problem, the teaching electrical pointer instrument that the utility model provides comprises gauge outfit, gauge outfit base, described gauge outfit base is provided with binding post, described binding post comprises metal screws, nut and insulating part, it is characterized in that described gauge outfit comprises the watch core plate of table cover and band watch core, described table cover is fixed on watch core plate, and described watch core plate is removably mounted on gauge outfit base.
The utility model adopts gauge outfit and the activity of gauge outfit base to install, be convenient to the depot repair of described electricity pointer instrument, when the gauge outfit well damage of described electricity pointer instrument and other structures are intact time, can by changing described electricity pointer instrument gauge outfit and retaining other structures recycling, not only reduce maintenance cost like this, also achieve the Appropriate application of table body resource.
The further improvement project of the teaching electrical pointer instrument that the utility model provides: described watch core plate and gauge outfit base through screws are installed or clamping is installed.
The preferred plan that the utility model provides is that watch core plate and the clamping of gauge outfit base are installed, compared with movable mountings described in other, interface arrangment and watch core plate one-body molded, easy for installation and with low cost, described interface arrangment comprises annular clamping, barb clamping etc.
Further improvement of the utility model scheme: the described arbitrary surface of watch core plate is set to front, another surface of watch core plate is set to the back side, the center in described front is provided with circular groove, the bottom surface of described circular groove is provided with tubbiness cavity volume, described tubbiness cavity volume extends to the back side by the front of watch core plate, watch core is provided with in tubbiness cavity volume, the outer rim of described watch core back circular groove is provided with the barb of some positional symmetry, described gauge outfit base is provided with the circular port mated with circular groove, and the outer rim of described circular port is provided with and the hole clipping of form fit corresponding with described barb position.
Adopt technique scheme, the watch core that is set to of circular groove provides installing space, the barb of positional symmetry on watch core plate, and stably can be fixed on gauge outfit base by watch core plate, described overhead structure is easy for installation and removal.
Further improvement of the utility model scheme: described gauge outfit base is provided with the mounting hole of binding post, the shoulder rank of mating with nut are provided with in described mounting hole, the height on described shoulder rank is no more than the thickness of nut, when gauge outfit base installs binding post, put into by nut on the shoulder rank of described mounting hole, the screw rod of described metal screws stretches out and and nut from mounting hole gauge outfit base inner wall.
Adopt technique scheme, the nut for link post plays position-limiting action, solves when binding post repeatedly uses and problem that nut relatively rotates and causes binding post to get loose.
