Abstract
The utility model relates to an auxiliary electrode reinforced platinum-wire joint three-electrode electrolytic base, the auxiliary electrode is composed of a screw head, a screw cap, and a screw stem joint, and is characterized in that the screw head is screwed to the screw cap, the auxiliary electrode platinum wire is inserted in the center of the screw head and in the center of the screw cap the screw stem joint is arranged, the screw cap is screwed to the screw stem joint, and an electric circuit is formed by contacting the auxiliary electrode platinum wire with the screw cap which is screwed along the screw head. The device is characterized in that the circuit is formed by clipping the screw stem joint with an alligator clip attached to a wire, hence protecting three-electrode electrolytic bases from being damaged when an alligator clip is used to directly clip the exposed joint of the auxiliary electrode platinum wire, which easily be broken. The design is reliable, robust, and easy to operate, and prevents fluid leakage caused by alligator clip loosening and in turn failed sealing devices.
Description
1. technical field the utility model belongs to galvanochemistry polarogram and volt-ampere analysis experiment three-electrode cell modifying device.This utility model is particularly related to a kind of being applicable to when doing polarogram and volt-ampere analysis experiment, prevents the three-electrode cell that auxiliary electrode (also claiming electrode) platinum filament joint is fractureed.
2. when polarogram or volt-ampere analysis experiment are done in the background technology laboratory; a kind of like this phenomenon takes place in regular meeting; just used three-electrode cell soon; its auxiliary electrode platinum filament exposes the crocodile clip clamping that joint do not had lead and has just been fractureed several times; therefore a three-electrode cell that is worth costliness has been scrapped, and experiment is forced to end.
3. utility model technology contents the purpose of this utility model just is to solve an above-mentioned difficult problem, be the experimental study person, Faculty and Students provide a kind of novel structure, technology reliable, durable in use, easy to operate, when doing polarogram and volt-ampere analysis experiment, the three-electrode cell of auxiliary electrode platinum filament joint reinforced.
The technical solution of the utility model is achieved in that this three-electrode cell comprises that the auxiliary electrical that is made of thread head and thread cap is extreme.Thread head and thread cap are by being threaded.Thread head central authorities are interspersed with the auxiliary electrode platinum filament.Thread cap central authorities have the screw rod joint, and thread cap and screw rod joint are by being threaded.During thread cap precession thread head, the auxiliary electrode platinum filament contacts with thread cap, forms circuit loop.This three-electrode cell auxiliary electrode platinum filament material is a metal platinum; Thread cap and screw rod joint are metal material.
Obviously, the utility model not only can protect the platinum filament joint to fracture because of being held when forming circuit loop with having the crocodile clip clamping screw rod joint of lead, also can avoid it loosening therefrom, causes sepage.
4. description of drawings is described further this usefulness is novel below in conjunction with accompanying drawing.Accompanying drawing is the structure cut-open view of the utility model auxiliary electrode one end.
Among the figure: 1, thread head 2, auxiliary electrode platinum filament 3, thread cap 4, screw rod joint
Embodiment as shown in the figure, the utility model auxiliary electrical extremely is to be made of thread head 1 and thread cap 3.Thread head 1 and thread cap 3 are by being threaded.Thread head central authorities are interspersed with auxiliary electrode platinum filament 2.Thread cap 3 central authorities have screw rod joint 4, and thread cap 3 and screw rod joint 4 are by being threaded.During thread cap 3 precession thread heads 1, auxiliary electrode platinum filament 2 contacts with thread cap 3, forms circuit.These three-electrode cell auxiliary electrode platinum filament 2 materials are metal platinum, and thread cap 3 and screw rod joint 4 are metal material.
After adding liquid to be measured in the utility model, insert hanging mercury electrode, contrast electrode, behind each joint and polarograph with the lead connection hanging mercury electrode that has crocodile clip, contrast electrode, auxiliary electrode, can drop into and analyze experiment.Electric current passes through liquid to be measured, auxiliary electrode platinum filament 2, and thread cap 3, screw rod joint 4 forms the loop with having the lead of crocodile clip, enters test mode.
One of peculiar technology of the present utility model is, the crocodile clip that has lead is clamped the screw rod joint and is formed circuit, this just avoided fully having lead the direct de-clamping auxiliary electrode of crocodile clip platinum filament expose joint the time, it is fractureed, cause three-electrode cell to scrap true generation.
Two of peculiar technology of the present utility model is, can avoid the auxiliary electrode platinum filament because of become flexible with the clamping of the crocodile clip that has lead, makes seal failure, causes liquid to be measured along between loosening auxiliary electrode platinum filament and thread head slit and the generation of the fact that outflows.
Claims (2)
1, a kind of auxiliary electrode platinum filament joint reinforced three-electrode cell, comprise that the auxiliary electrical that is made of thread head and thread cap is extreme, it is characterized in that thread head and thread cap are by being threaded, thread head central authorities are interspersed with the auxiliary electrode platinum filament, thread cap central authorities have the screw rod joint, and thread cap and screw rod joint are by being threaded, during thread cap precession thread head, the auxiliary electrode platinum filament contacts with thread cap, forms circuit loop.
2, auxiliary electrode platinum filament joint reinforced three-electrode cell according to claim 1 is characterized in that auxiliary electrode platinum filament material is a metal platinum, and thread cap and screw rod joint are metal material.
