[0002] Metal materials refer to materials with properties such as gloss, ductility, easy conductivity and heat transfer. Metal materials need to be tested for corrosion performance during use to evaluate their corrosion resistance.

The box body 100 is provided with a driving member for driving the rotating roller 202 to rotate, and the driving member includes a driving motor 200 fixed to the back of the box body 100 and two sets of tooth plates 215. The front and back of the track frame 208 are provided with T-shaped slide grooves. When the tooth plate 215 moves, it drives the sliding frame 217 below to slide in the T-shaped slide groove. The internal sliding of the T-shaped slide groove is provided with multiple sets of sliding frames 217, and the bottom of the tooth plate 215 is fixed on the sliding frame 217. A first gear ring 218 is fixedly disposed at the working end of the driving motor 200, an upper rotating rod 209 is rotatably disposed inside the box body 100, and an upper outer ring 216 is fixedly disposed at one end of the upper rotating rod 209; The first gear ring 218 is internally connected with a first screw rod 228 by a thread. The first screw rod 228 is tightened, and the first screw rod 228 is fixed to the upper outer ring 216. The roller 202 can be driven to rotate by the driving motor 200. The working end of the first screw rod 228 extends to the surface of the upper outer ring 216. The outer sides of both ends of the rotating roller 202 are sleeved with upper gears 212, which mesh with the toothed plates 215. A recessed frame 211 is fixedly arranged between the bottoms of the two sets of toothed plates 215. A return-shaped body 226 is fixedly arranged at the bottom of the recessed frame 211. When the recessed frame 211 descends or ascends, the return-shaped body 226 is driven to move up and down on the vertical plate 210.

The other end of the upper rotating rod 209 is fixedly arranged with Connecting rope 223, an L-shaped frame 220 is fixedly provided on the inner wall of the box body 100, the bottom of the vertical plate 210 passes through the inside of the L-shaped frame 220, two sets of limit plates 227 are fixedly provided on the outer side of the bottom of the vertical plate 210, and a connecting spring is fixedly provided between the vertical plate 210 and the L-shaped frame 220. When the upper rotating rod 209 is reversed, the connecting rope 223 wound on the upper rotating rod 209 will be loosened, and then the vertical plate 210 will be reset to drive the connecting spring to reset to the original position.

[0021] During use, the metal material sample is placed on the multiple groups of rollers 202 in the box body 100, and then the box cover 101 is closed to perform a salt spray corrosion test, and then the drive motor 200 is turned on.

The upper rotating rod 209 rotates to tighten and wind up the connecting rope 223 at the other end of the upper rotating rod 209, driving the vertical plate 210 to move in the direction close to the upper rotating rod 209. The vertical plate 210 drives the upper circular body 226 and the recessed frame 211 to move. At this time, the bottom of the vertical plate 210 will slide inside the L-shaped frame 220. The L-shaped frame 220 can limit the movement of the vertical plate 210 to increase stability. When the plate 210 moves, the connecting spring is stretched. When the recessed frame 211 moves, the two sets of toothed plates 215 above are driven to move. The sliding frame 217 at the bottom of the toothed plate 215 slides in the T-shaped groove in the track frame 208. Then, through the meshing action of the toothed plate 215 and the upper gear 212 above, the lower gear 212 starts to rotate, driving the roller 202 to rotate. At this time, the metal material sample located on the roller 202 moves with the rotation of the roller 202. When it moves to a suitable position, it operates according to the opposite principle mentioned above. The drive motor 200 is reversed, indirectly driving the roller 202 to rotate in the opposite direction, and so on and so forth, so that the salt mist sprayed by the spray head 103 contacts the bottom of the metal material sample, thereby also performing corrosion testing on the bottom.

[0022] Embodiment 2 Based on Example 1, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 and Fig.12The lifting assembly includes a lower rotating rod 206 rotatably arranged inside the box body 100, and one end of the lower rotating rod 206 is respectively sleeved with a lower bearing 224 and a lower outer ring 225. When the first gear ring 218 rotates, it will drive the second gear ring 219 below to rotate. When the working end of the second screw rod 229 does not contact the lower bearing 224, the second gear ring 219 rotates under the action of the lower bearing 224 between the second gear ring 219 and the upper rotating rod 209, and the lower rotating rod 206 will not rotate accordingly. The outer wall of the lower bearing 224 is fixedly provided with a second gear ring 224. 19, the first gear ring 218 is meshed with the second gear ring 219, the interior of the lower outer ring 225 is connected with the second screw 229 by thread, and the working end of the second screw 229 extends to the surface of the lower bearing 224, the working end of the first screw 228 is no longer in contact with the upper outer ring 216, after the working end of the second screw 229 is in contact with the lower bearing 224, the screw 204 can be driven to rotate by the driving motor 200, and the screw 204 can be driven to rotate forward or reverse by the forward or reverse rotation of the driving motor 200, thereby driving the roller 202 to rise or fall; The other end of the lower rotating rod 206 is sleeved with a second bevel gear 222, and the bottom of the inner wall of the box body 100 is rotatably provided with a T-shaped rotating column 207, and the top of the T-shaped rotating column 207 is fixedly provided with a first bevel gear 221, and the second bevel gear 222 is meshed with the first bevel gear 221; Nut seats 203 are fixedly set at the four corners of the track frame 208. When the screw rod 204 rotates forward or reversely, the nut seat 203 can move up and down. The screw rod 204 is rotatably set inside the nut seat 203. The bottom of the screw rod 204 is rotatably set at the bottom of the inner wall of the box body 100. A rotating wheel 213 is fixedly set on the outer side of the bottom of the screw rod 204. The outer part of the rotating wheel 213 is sleeved with a transmission belt 205, and the outer part of the T-shaped rotating column 207 is in contact with the transmission belt 205.

[0023] The present invention is designed with a moving mechanism. After placing the metal material sample on the multiple groups of rollers 202 during use, the tooth plate 215 is driven by the driving motor 200 to move back and forth in both directions during the subsequent corrosion test, thereby driving the rollers 202 to rotate, so that the metal material sample placed on the rollers 202 is moved. At this time, the bottom of the metal material sample can be in contact with the sprayed salt mist. Moreover, when a larger volume of metal material sample is placed on the rollers 202, the nut seat 203 on the track frame 208 is driven by the driving motor 200 to descend again, thereby driving the metal material sample placed on the rollers 202 to descend. The larger volume of metal material sample can be accommodated. When the larger volume of metal material sample is tested, the bottom of the metal material sample can also be fully in contact with the salt mist, thereby increasing the test effect of the metal material sample and the accuracy of the test structure.

[0024] When the volume of the metal material sample to be tested is large, the first screw 228 is rotated outward to make the working end of the first screw 228 disengage from the surface of the upper outer ring 216, and then the second screw 229 below is rotated in the direction close to the lower bearing 224, and then the working end of the second screw 229 contacts the surface of the lower bearing 224, so that the second screw 229 is connected and fixed to the lower bearing 224, and then the driving motor 200 is turned on, and the working end of the driving motor 200 drives the first gear ring 218 to rotate, driving the second gear ring 219 meshing therewith to rotate, thereby driving the lower bearing 224, the lower rotating rod 206 and the second bevel gear 222 to rotate, and the second bevel gear 222 drives the first bevel gear 221 meshing therewith to rotate. , thereby driving the T-shaped rotating column 207 to rotate, and then the transmission belt 205 is driven to rotate through the T-shaped rotating column 207, and the transmission belt 205 drives the rotating wheel 213 at the bottom of the screw rod 204 to rotate, and then the rotating wheel 213 can drive the screw rod 204 to rotate, and then the nut seat 203 located on the track frame 208 moves downward, driving the track frame 208, the roller 202 and the large volume of metal material samples placed on the roller 202 and other structures to move downward, and stop when moving to the appropriate position, and then rotate the second screw rod 229 outward to make the working end separate from the surface of the lower bearing 224, and then rotate the first screw rod 228 toward the upper outer ring 216 and lock it, and then the salt spray test operation can be carried out.

[0025] Embodiment 3 Based on Example 2, please refer to Figure 3 , Figure 4 , Figure 5 , Fig. 9 and Fig.13 A spray component is provided at the bottom of the track frame 208, and the spray component includes a circular tube 302 fixed on the inner wall of the recessed frame 211 and a concave plate 301 fixed between two groups of nut seats 203. A plurality of rotary joints 303 are provided on the top of the circular tube 302. The rotary joints 303 are used between the spray head 304 and the circular tube 302 to enable the spray head 304 to rotate under the drive of an external force. The rotary joint 303 is provided with a spray head 304, and a mounting ring 305 is fixedly sleeved on the outside of the spray head 304. The outer wall of the mounting ring 305 contacts the concave plate 301. A telescopic soft water pipe 300 is fixedly provided at the bottom of the circular tube 302, and the end of the telescopic soft water pipe 300 extends to the outside of the box body 100.

[0026] The present invention uses a designed spray component. After the corrosion test is completed, the spray head 304 on the spray component is turned on to spray and clean the metal material sample placed on the roller 202. During the cleaning process, the spray head 304 moves along with the movement of the tooth plate 215. At the same time, the spray head 304 rotates, thereby increasing the spray cleaning effect on the upper metal material sample. There is no need to take it out for cleaning again later, which saves operation time and operation steps and improves the efficiency of the test.

[0027] During use, the end of the telescopic soft water pipe 300 is connected to an external water supply device. When the test is completed, the water supply device is turned on to supply water to the telescopic soft water pipe 300. Then the water enters the spray head 304 through the loop pipe 302 and the rotating joint 303, and is sprayed toward the metal material sample above through the spray head 304 to clean and spray the salt mist attached to the surface of the sample. At the same time, since the loop pipe 302 is fixed on the recessed frame 211, when the recessed frame 211 follows the reciprocating movement of the toothed plate 215, it will also drive the loop pipe 302 to move, and the loop pipe 302 drives the spray head 304 to move. Moreover, when the spray head 304 moves, the mounting ring 305 located outside the spray head 304 contacts and rotates with the recessed plate 301, driving the spray head 304 to rotate, so that the spray head 304 can be rotated while reciprocating and spraying, thereby increasing the spray cleaning effect on the metal material sample.

[0028] Embodiment 4 Based on Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig.14 A pipeline 401 is fixedly arranged on the nut seat 203, and a plurality of nozzles 402 are arranged on the top of the pipeline 401.

A telescopic soft air tube 400 is fixedly arranged at the bottom of the pipeline 401, and the bottom of the telescopic soft air tube 400 extends to the outside of the box 100.

[0029] The present invention combines the designed pipeline 401, the nozzle 402 and the telescopic soft air tube 400. After the metal material sample is sprayed and cleaned, the nozzle 402 is turned on to blow air on the surface of the metal material sample to dry the wet surface of the metal material sample that is covered with liquid, so as to facilitate subsequent operators to take out the metal material sample from the box 100, reduce the situation where the liquid on the surface of the metal material sample wets the operator's hands when taking it out, and facilitate the operator to operate.

[0030] During use, an air supply device is connected to the end of the telescopic soft air tube 400. When spraying is completed, the air supply device is turned on to provide gas to the pipeline 401. Then the gas is blown toward the surface of the metal material sample through the nozzle 402 to dry the liquid attached to the surface of the metal material sample, thereby reducing the situation where the liquid on the surface of the metal material sample wets the hands of people when taking it.

[0031] In this embodiment, the back of the box cover 101 is rotatably connected to the box body 100 through two sets of hinges, a controller 102 is provided on the side of the box body 100, and a spray head 103 is provided on the inner wall of the box cover 101, through which salt mist is sprayed.
