Abstract

The utility model relates to an electric meter, comprising a casing (12), a dial plate (13) and a circular winding repulsion type measuring mechanism. A supporting frame (3) is fixed on the upper end of the supporting column (9) arranged on seat of a casing (16), and the supporting frame (3) is extended upwards at both sides of a rotating shaft to form two upper supporting frame vertical columns (17). The utility model is characterized in that the two upper supporting vertical columns (17) are transversely extended to form the rotating shaft upper supporting frame (4). The utility model can reduce assembling procedure, and the production cost of the utility model can be reduced.

Description

Ammeter

The utility model relates to a kind of reometer or voltage table that is used to measure alternating current.

In the prior art, the reometer of measurement alternating current or voltage table are shown in accompanying drawing 2 and accompanying drawing 3, it comprises shell, is located at the interior set circular coil repulsion type measuring mechanism of dial plate, shell on the shell, described circular coil repulsion type measuring mechanism is to be provided with coil on fixing coil former, the inwall of described coil former is provided with secured core, the axle center of described coil former is provided with rotating shaft, fixing the inside that movable core and this movable core are positioned at coil in this rotating shaft, described rotating shaft top is fixed with pointer; Be fixed with pillar on the base of described shell, the upper end of this pillar is fixed with support with screw, this support extends to form the rotating shaft lower carriage in coil, described rotating shaft bottom and rotating shaft lower carriage flexibly connect, described support extends upward in the both sides of rotating shaft and forms two upper bracket columns, be fixed with horizontal rotating shaft upper bracket [4] with screw [14] on described two upper bracket columns, described support, upper bracket column are the integrative-structures that plastics are made, but rotating shaft upper bracket [4] is an independently part of metal making.This is because the rotating shaft upper bracket will be adjusted button with zero-bit and be connected, and the rotating shaft upper bracket that general plastics are made has static, easily influences the zero potential indication of pointer.To influence assembling speed with two screw fixed rotating shaft upper brackets [4] and upper bracket column when but this kind structure makes assembling, improve production cost.

The purpose of this utility model is to provide a kind of ammeter simple in structure.

The technical solution of the utility model is: the ammeter of this patent indication is reometer or a voltage table of measuring alternating current, it comprises shell, is located at the interior set circular coil repulsion type measuring mechanism of dial plate, shell on the shell, described circular coil repulsion type measuring mechanism is to be provided with coil on fixing coil former, the inwall of described coil former is provided with secured core, the axle center of described coil former is provided with rotating shaft, fixing the inside that movable core and this movable core are positioned at coil in this rotating shaft, described rotating shaft top is fixed with pointer; Be fixed with pillar on the base of described shell, the upper end of this pillar is fixed with support, this support extends to form the rotating shaft lower carriage in coil, described rotating shaft bottom and rotating shaft lower carriage flexibly connect, and described support extends upward in the both sides of rotating shaft and forms two upper bracket columns; Described two upper bracket columns horizontal expansion again form rotating shaft upper bracket, described support, upper bracket column, the as a whole structure of rotating shaft upper bracket; The upper end of described rotating shaft upper bracket and rotating shaft flexibly connects, and described rotating shaft is connected with an end of hairspring, and the zero-bit adjustment button that is provided with on the other end of described hairspring and the rotating shaft upper bracket is connected.

The utility model compared with prior art has following advantage:

Because rotating shaft upper bracket and support are structure as a whole,, can reduce production costs so can omit operation one during assembling with screw connection rotating shaft upper bracket and support.Rotating shaft upper bracket and support are all soaked with antistatic liquid, so can not influence the zero potential of meter pointer because of static.

The utility model will be further described below in conjunction with drawings and Examples:
