[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0036] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a silver plating corrosion resistance testing device.

[0038] Example 1:

[0039] Combination Figures 1-6 As shown, the present invention provides a silver plating corrosion resistance testing device, including a testing mechanism 100, a sealing mechanism 200 disposed on the testing mechanism 100, two sets of mimicry pressurization mechanisms 300 disposed within the sealing mechanism 200, and a silver plating sample 400 disposed horizontally within the testing mechanism 100. The testing mechanism 100 is used to provide a suspended testing platform for the silver plating sample 400. The sealing mechanism 200 is used to seal the two partitions of the testing mechanism 100 and provide an effective carrier for the two sets of mimicry pressurization mechanisms 300. The mimicry pressurization mechanism 300 is used to apply a gradual testing pressure and allow liquid overflow to one end of the silver plating sample 400 in the partition.

[0040] The testing mechanism 100 includes a first base 110, a housing 120 disposed on the first base 110, two sets of pressure measuring components 180 disposed inside the first base 110, a second base 160 installed in the middle of the first base 110, a sealing block 170 movably installed directly above the second base 160, and four observation windows 130 disposed on four slots in the housing 120.

[0041] Two pads 150 are provided inside the first base 110;

[0042] The outer wall of the housing 120 is provided with a pad, and a pressure boosting screw 140 is provided inside the pad;

[0043] The top end of the pressure boosting screw 140 is movably installed inside the end plate at the outer end of the top plate 210;

[0044] The sealing mechanism 200 includes a top plate 210 disposed at the top of the housing 120, two sliding covers 220 mounted on the top of the top plate 210, a vertical plate 270 movably mounted inside the sliding covers 220, and a cover 230 mounted at the bottom of the vertical plate 270.

[0045] The mimicry pressurization mechanism 300 includes a sheath 310 disposed inside the cover 230, a vertical tube 330 installed inside the sheath 310, a pressurization end 350 disposed at the bottom of the vertical tube 330, a rubber pad 380 disposed outside the pressurization end 350, an inlet tube 320 disposed at the top of the sheath 310, a plug 340 disposed on the vertical tube 330, a top cover 370 disposed outside the plug 340, and a spring 360 disposed outside the vertical tube 330.

[0046] The booster end 350 has a hemispherical structure, and the surface of the booster end 350 is provided with evenly distributed slots.

[0047] The bottom of the rubber pad 380 has evenly distributed overflow holes, and the top of the rubber pad 380 is installed in the annular groove on the inner wall of the top cover 370.

[0048] After the pressure boosting screw 140 rotates counterclockwise, the sealing mechanism 200 can be removed as a whole. Then, the sealing block 170 and the two pads 150 are pulled outward. Then, the selected size of the electroplated silver sample 400 is placed along the inner cavity of the outer shell 120 until the electroplated silver sample 400 is effectively supported by the second base 160. Then, the pressure boosting screw 140 is controlled to rotate clockwise until the sealing mechanism 200, together with the sealing block 170, fixes and presses the electroplated silver sample 400. At this time, both ends of the electroplated silver sample 400 will be exposed in the two partitioned cavities inside the outer shell 120.

[0049] As the two inlet pipes 320 selectively inject sweat at different temperatures, the solution is transferred along the vertical pipe 330 to the inside of the pressurizing end 350. After the outer end of the jump plate 240 is pressed and flipped upward, the pressurized vertical plate 270 controls the cap 230 to descend. At this time, the suspended mimicry pressurizing mechanism 300 can pressurize the exposed end of the electroplated silver sample 400, and the sweat solution that is squeezed out can be used to perform top-down inspection on the pressurized surface of the electroplated silver sample 400, thereby effectively simulating the corrosion resistance of the electroplated silver sample 400 to sweat in natural environment.

[0050] Example 2:

[0051] Combination Figure 1 , Figure 5 as well as Figure 6 As shown, based on Embodiment 1, the pressure measuring assembly 180 includes a column 181 installed inside the first base 110, a sealing tube 182 installed in the bottom vertical groove of the column 181, a flow transfer element 183 disposed in the column 181 and the sealing tube 182, and a drain pipe 184 installed at the outer end of the flow transfer element 183.

[0052] The top of the column 181 is provided with a pressure-bearing groove, and the inside of the column 181 is provided with a main line drainage hole;

[0053] The pad 150 is made of silicone material, and the inner wall of the bottom end of the pad 150 has a slot, into which the end adapter of the electroplated silver sample 400 is snapped.

[0054] Preferably, the top of the first base 110 is provided with two symmetrically distributed vertical holes, and the bottom end of the column 181 is adapted to be installed in the vertical holes. At this time, the sealing tube 182 is installed inside the first base 110, and the horizontally placed sealing tube 182 can provide overflow protection for the pipe of the transfer component 183.

[0055] As the test continues, sweat drips down the surface of the electroplated silver sample 400 and then flows down the outer wall of the column 181. The sweat solution is then transferred from the groove at the bottom of the column 181 into the vertical hole. Finally, the sweat solution flows into the pipe through the groove at the inner end of the transfer component 183 and is drained out through the drain pipe 184.

[0056] Example 3:

[0057] Combination Figure 3 and Figure 5 As shown, based on Embodiment 1, the sealing mechanism 200 further includes a jump plate 240 movably mounted on the outer end clamp of the sliding cover 220, and the bottom end of the jump plate 240 is movably mounted on the top of the vertical plate 270.

[0058] The outer wall of the sliding cover 220 is provided with a sliding track;

[0059] The top of the vertical plate 270 is provided with a horizontally placed positioning screw 250, and the positioning screw 250 is adapted to extend through the outside of the slide rail. A nut 260 is provided on the threaded section of the positioning screw 250 extending through the outside of the slide rail.

[0060] Preferably, the outer side of the cover 230 is provided with an arc-shaped groove, and the inner end of the cover 230 is adapted to fit against the outer wall of the top plate 210. When the outer end of the control jump plate 240 is flipped upward, the pressure applied by the vertical plate 270 will drive the cover 230 to descend stably. Finally, the simulated pressure boosting mechanism 300, which is set in the middle of the cover 230 and suspended, can press down on the exposed ends of the electroplated silver sample 400. Finally, the two sets of simulated pressure boosting mechanisms 300 can be used in conjunction with sweat of different temperatures to conduct corrosion resistance tests on the surface of the electroplated silver sample 400 under pressure.

[0061] The working principle and usage process of this utility model are as follows: Select an electroplated silver sample 400 of appropriate size, then take out the pressure boosting screw 140 counterclockwise, then take out the sealing mechanism 200 as a whole from the inside of the outer shell 120, then remove the sealing block 170 and the two pads 150, then snap the two ends of the electroplated silver sample 400 into the grooves on the inner side of the two pads 150, and then use the sealing block 170 to press the electroplated silver sample 400 onto the second base 160.

[0062] Once the electroplated silver sample 400 is effectively pressed and fixed, both ends of the electroplated silver sample 400 will be exposed in the two cavities of the outer shell 120, and at this time, both ends of the electroplated silver sample 400 will be attached to the tops of the two pillars 181.

[0063] As the pressure boosting screw 140 is tightened clockwise onto the end plate outside the housing 120, the sealing mechanism 200 as a whole will carry the two sets of mimicry pressure boosting mechanisms 300 and press them down toward the exposed ends of the electroplated silver sample 400.

[0064] When the two inlet pipes 320 transfer the sweat solution into the two vertical pipes 330, by changing factors such as the temperature of the input sweat, the two types of sweat solutions can be squeezed out by the two springs 360 and finally overflow through the groove at the bottom of the rubber pad 380 until the two jump plates 240 are selected to flip upward, and finally the two vertical plates 270 will drive the two caps 230 to fall downward.

[0065] At this point, the two sets of simulated pressure boosting mechanisms 300 suspended can selectively apply test pressure to the exposed ends of the electroplated silver sample 400. By comparing the corrosion rate of the electroplated silver sample 400 coating by sweat under different pressure test conditions, the accurate data of electroplated silver corrosion by sweat can be effectively detected.

[0066] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
