Abstract
The utility model discloses a precious metal identifying device which comprises reference metal (1), an electrolyte holding layer (2), a display terminal (3), a wire (4) and a probe (5). The electrolyte holding layer (2) is fixed on one side of the reference metal (1), the other side of the reference metal (1) is connected with the display terminal (3) through the wire (4), and the other side of the display terminal (3) is connected with the probe (5). During usage, an object to be tested is placed between the electrolyte holding layer (2) and the probe (5), and the category of the precious metal is determined by use of the data of the display terminal (3). The precious metal identifying device has the characteristics of simple structure, convenience for carrying and use, and no limitation and impact by ambient conditions.
Description
Technical field:
The utility model relates to metal and differentiates field, a kind of specifically precious metal identification device.
Background technology:
Precious metal is differentiated more in sector applications such as commemorative coin collections.Currently used precious metal discrimination method adopts draining weight method and chemical method more.These two kinds of methods exist inherent defects such as complicated operation, cause differentiating that noble metal is convenient inadequately.
Summary of the invention:
The utility model provides a kind of easy device of differentiating precious metal, can identify precious metals such as gold, silver easily.
The technical solution adopted in the utility model is:
A kind of precious metal identification device is characterized in that: include norm metal (1), electrolyte sustaining layer (2), display terminal (3), lead (4) and probe (5) five parts and constitute; Described electrolyte sustaining layer (2) places norm metal (1) upper surface, and electrolyte sustaining layer (2) surface is used to place tested metal; Described norm metal (1) is connected with display terminal (3) by lead, two probes of the different metal material that described probe (5) includes copper billet (7), be coated on the outer insulation course of copper billet (7), copper billet (7) front end is electrically connected are formed, and copper billet (7) is connected with display terminal by lead.
Described two probes are high and low position and are arranged into step-like.
Described norm metal (1) is solid metallic simple substance or solid metallic alloy.
Described electrolyte sustaining layer is kept contained structure by electrolytic solution and electrolytic solution and is formed.
Described electrolyte sustaining layer (2) is the cotton that soaked in saturated aqueous common salt, and display terminal (3) is that a range is the voltage table of 0-2 volt.
Described probe is selected all kinds of solid-state precious metal simple substance or solid-state noble metal alloy or is used in combination.
Described probe is selected golden contact probe and silver contact probe respectively.
The beneficial effects of the utility model are:
A kind of precious metal identification device that the utility model provides is made of norm metal, electrolyte sustaining layer, display terminal, connection lead and five parts of popping one's head in.It is simple in structure, is easy to carry, and is convenient to use, can identify precious metal in a short period of time.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of probe.
Embodiment:
Referring to Fig. 1-2;
A kind of precious metal identification device is made of norm metal zinc 1, electrolyte sustaining layer 2, display terminal 3, lead 4 and 5 five parts of popping one's head in.Electrolyte sustaining layer 2 is the cotton that soaked in saturated aqueous common salt; Display terminal 3 is that a range is the voltage table of 0-2 volt.This electrolyte sustaining layer 2 is fixed on a side of norm metal zinc 1, and the opposite side of norm metal zinc 1 is connected to display terminal 3 by lead 4, and display terminal 3 opposite sides connect probe 5 by connecting lead 4.Display terminal 3 can show the voltage signal or the current signal of input as required.
Structure such as Fig. 2 of probe 5, it is made up of probe copper material 7, probe insulation layer 8, connection lead 5, probe silver point 10, probe gold point 11.Probe copper material 7 front ends are done step fixedly connected probe silver point 10, probe gold point 11 respectively.Probe copper material 7 rear ends connect lead 5.Probe copper material 7 wraps probe insulation layer 8 near connecting lead 5 one sides.
During use, the silver point 10 of will popping one's head in earlier, probe gold point 11 place respectively on the electrolyte sustaining layer 2, and write down display terminal 3 data.Then, tested article 6 placed electrolyte sustaining layer 2 and pop one's head between 5, data by display terminal 3 and front write down two groups of data to recently distinguishing the precious metal kind.
