Description
Technical field
The utility model belongs to field of electrical equipment, particularly relates to a kind of instrument transformer being convenient to install.
Background technology
Now, instrument transformer on the market is normally provided with installation portion on angle, four, bottom, in order to fixedly mount instrument transformer.When but installation occasion varies, installation portion on four angles, bottom goes for most installation occasion, but when some mounting parts are just not competent when instrument transformer top, and some installing space is too narrow and small, the installation portion of evagination affects the fixing of instrument transformer.
Summary of the invention
A kind of instrument transformer being convenient to install that the purpose of this utility model is to overcome deficiency of the prior art and invents.
The utility model is achieved in that a kind of instrument transformer, comprise housing, iron core and secondary terminals, described housing is rectangle, iron core is arranged in housing, housing is provided with secondary terminals, it is characterized in that: eight drift angle places of described housing are provided with groove, the upper top surface being parallel of the upper end face of groove and bottom surface and housing, the upper end face of groove is provided with shaft hole and screw hole, the rotating shaft moved towards up and down is provided with in shaft hole, screw is provided with in screw hole, described rotating shaft two ends are cylindric, the centre of rotating shaft is rectangle, rotating shaft in groove is provided with installation portion, an installation portion part is in groove, a part reaches outside housing, described installation portion is provided with the guide rail hole of strip, two sides of guide rail hole and two sides of rotating shaft intermediate rectangular fit, rotating shaft linearly can be slided in the horizontal direction in guide rail hole, the end face of guide rail hole is provided with pilot hole, spring is provided with in pilot hole, the other end of spring and rotating shaft joint, groove outside housing is provided with fixing hole and location hole.
Further, described installation portion outer surface is provided with rubber layer.
The utility model has the following advantages:
Housing is provided with altogether eight installation portions, installation portion is arranged in the groove on housing, installation portion can rotate around rotating shaft, be provided with spring between rotating shaft and installation portion in groove, spring firmly outwards extrudes installation portion, to the power that installation portion is outside once, the strip guide rail hole that installation portion is arranged contacts with the rectangle in rotating shaft, thus limit multiple degree of freedom, make installation portion can only slide anteroposterior, ensure to install, be connected firmly by above-mentioned measure; When certain installation portion is not used time, firmly can press this installation portion in groove, spring between groove and installation portion is compressed, when the screw hole on housing and location hole are just right up and down time, by in the location hole on housing inner bolt precession installation portion, thus this installation portion is stuck in groove, thus when ensureing that instrument transformer is installed, does not have unnecessary installation portion and interfere installation.
