Abstract

The invention discloses a coaxial double-pointer electrical instrument comprising a rotating knob, a main instrument body and an index disk. A first electromagnet is mounted at one side of the inner end of the main instrument body; a second electromagnet is connected to one end of the first electromagnet; a coil is arranged at the side of the second electromagnet; and a fastening rack winds aroundthe outer end of the coil. A first linkage rod is connected to one side of the coil in a rotating manner; and a second linkage rod is connected to other side of the coil in a rotating manner. A spring is installed at the center of the second linkage rod. The index disk is installed at the upper end of the center of the main instrument body; and a first pointer and a second pointer are connected to the center of the inner end of the index disk. A protective case sleeves the outer end of the main instrument body; a rotary knob is connected to the lower end of the center of the main instrument body in a rotating manner; a pressing button is installed at the top of the inner end of the rotary knob; and a clamp frame is arranged at the lower end of the pressing button. According to the coaxialdouble-pointer electrical instrument, adjustment is realized by setting the rotary knob.

Description

technical field [0001] The invention relates to the technical field of electrical instrumentation equipment, in particular to a coaxial double-pointer electrical instrument. Background technique [0002] Electrical instruments are the general term for the technical tools required in the process of electromagnetic measurement. Commonly used electrical instruments are classified into: indicating instruments, comparative instruments, digital instruments and itinerant detection devices, recording instruments and oscilloscopes, extended range devices and converters, but currently The coaxial double pointer electrical instrument has the following problems: [0003] One is that it is inconvenient to perform coaxial double measurement, which will cause some inconvenience, and the other is that the adjustment and clamping work cannot be performed, which needs to be improved. Contents of the invention [0004] The object of the present invention is to provide a coaxial double-point...
