[0002] Water-based paint is an environmentally friendly paint, mainly composed of water-based resins, pigments, additives, etc. In the working environment of metal equipment, it is very susceptible to corrosion caused by the surrounding environment, especially for equipment exposed to outdoor environments, the rate of corrosion is even more serious. In order to decorate and prevent such equipment from being corroded, the water-based paint system is applied, and the performance of the coating system must be tested. Therefore, in order to simulate the external corrosive environment, it is necessary to test the corrosion resistance of water-based paint through a salt spray tester.

[0043] Specifically, Figure 1 , Figure 5 , Figure 6 , Figure 7 and Fig.12 As shown, the right end of the connecting shaft 204 is fixedly connected with a rotating rod 207, the end of the rotating rod 207 is threadedly connected with a knob 208, the left end of the knob 208 is rotatably connected with a connecting ring 209, the left side of the connecting ring 209 is fixedly connected with a rubber pad 210, and the rubber pad 210 is in conflict with the transparent cover 203. When the internal situation of the salt spray machine body 1 needs to be observed through the transparent cover 203 during the test, the rotating rod 207 can be rotated. When the rotating rod 207 rotates, it will drive the connecting shaft 204 to rotate, and when the connecting shaft 204 rotates, it will drive the connecting rod 205 to rotate. The connecting rod 205 will drive the scraper 206 to scrape the water droplets on the inner wall of the transparent cover 203. The scraper 206 scrapes the water droplets on the inner wall of the transparent cover 203. When the metal parts inside the salt spray machine body 1 need to be observed during the test, the observation is clearer. At the same time, when the scraper 206 finishes scraping, by rotating the knob 208 on the rotating rod 207, the knob 208 will drive the connecting ring 209 to move close to the transparent cover 203, so that the connecting ring 209 drives the rubber pad 210 to press against the transparent cover 203, thereby fixing the rotating rod 207 to prevent the rotating rod 207 from rotating.

[0044] Specifically, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Fig.12 and Fig.13As shown, the driving structure 3 includes a gear 301 fixedly connected to the left end of the mounting shaft 202 and a rack 302 meshed with the rear of the gear 301, a mounting rod 303 is slidably connected to the salt spray machine body 1, a guide rod 305 is fixedly connected above the mounting rod 303, a guide plate 306 is fixedly connected to the left side of the salt spray machine body 1, the guide rod 305 is slidably connected to the guide plate 306, the rack 302 is fixedly connected to the mounting rod 303, a first tension spring 307 is fixedly connected between the mounting rod 303 and the guide plate 306, a connecting plate 304 is fixedly connected to the bottom of the mounting rod 303, the connecting plate 304 is slidably connected to the salt spray machine body 1, the mounting rod 303 is in an "L"-shaped structure, the The limiting structure 5 includes a limiting plate 501 slidably connected to the top of the connecting plate 304 and two limiting grooves 502 opened in front of the salt spray machine body 1. The limiting plate 501 is engaged with the limiting groove 502 below. A pull plate 503 is fixedly connected to the front of the limiting plate 501. A guide column 504 is fixedly connected to the front of the connecting plate 304. The pull plate 503 is slidably connected to the guide column 504. A second tension spring 505 is fixedly connected between the pull plate 503 and the connecting plate 304. When the placement rack 401 is installed inside the salt spray machine body 1, water can be added to the sealing groove 7. When a certain amount of water is added to the sealing groove 7, by pulling the pull plate 503 forward, the pull plate 503 moves more smoothly through the guide column 504, and the second The tension spring 505 stretches, and at the same time, the pulling plate 503 drives the limiting plate 501 to move forward, so that the limiting plate 501 is no longer engaged with the limiting groove 502 below. At this time, the connecting plate 304 and the mounting rod 303 will move upward under the action of the first tension spring 307, and the mounting rod 303 will drive the guide rod 305 to slide and cooperate with the guide plate 306. The setting of the guide rod 305 and the guide plate 306 makes the movement of the mounting rod 303 more stable. At the same time, the mounting rod 303 drives the rack 302 to move upward, and the rack 302 drives the gear 301 to rotate clockwise. When the gear 301 rotates, it drives the mounting shaft 202 to rotate, and the mounting shaft 202 rotates with the mounting seat 201. The mounting shaft 202 drives the transparent cover 203 to rotate clockwise. When the gear 301 rotates After rotating 90 degrees, the transparent cover 203 will be located in the sealing groove 7, and the limiting plate 501 will move upward to be aligned with the upper limiting groove 502. The pull plate 503 will drive the limiting plate 501 to engage with the upper limiting groove 502 under the action of the second tension spring 505. The limiting plate 501 cooperates with the two limiting grooves 502 on the salt spray machine body 1 to facilitate the fixing of the rotated transparent cover 203, thereby improving the stability of the transparent cover 203. At this time, the purified water is introduced into the brine tank, and an appropriate amount of salt powder or salt solution is added. The compressed air generated by the compressor is then sent to the spray tower 8 at the bottom of the brine tank. The spray tower 8 will atomize the brine into fine particles. The compressed air passes through the spray tower 8 to form a high-speed airflow in the brine tank.The salt water particles are brought into a suspended state. With the impact of the airflow, the salt water particles evaporate in the air to form salt mist. The salt mist is sprayed onto the surface of the test sample by the spray tower 8 to form a corrosive environment to test the corrosion resistance of the water-based coating.

[0045] Specifically, Figure 1 , Figure 3 , Figure 7 , Fig.10 , Fig.12 , Fig.14 , Fig.15 , Fig.16 , Fig.17 and Fig.18As shown, the placement structure 4 includes a placement rack 401 slidably connected to the inside of the salt spray machine body 1 and a cross bar 402 fixedly connected to the placement rack 401, two placement racks 401 are slidably connected in the salt spray machine body 1, four cross bars 402 are fixedly connected between the two placement racks 401, an anti-slip rod 403 is fixedly connected in the salt spray machine body 1, the placement rack 401 is slidably connected to the anti-slip rod 403, and the anti-slip rod 403 is in a "T" shape. A plurality of round rods 9 and a placement plate 10 are placed on the placement rack 401, a plurality of baffle rods 404 are slidably connected in the placement rack 401 on the right, two slide rods 405 are slidably connected in the placement rack 401 on the right, and a plurality of the baffle rods 404 are The rod 404 is fixedly connected to two sliding rods 405 respectively, and a pull rod 406 is fixedly connected above the sliding rod 405, and the pull rod 406 is slidably connected to the placement rack 401, and a slider 407 is slidably connected inside the pull rod 406, and the slider 407 contacts the placement rack 401 on the right, and a first screw rod 408 is rotatably connected above the pull rod 406, and the slider 407 is threadedly connected to the first screw rod 408, and a fixed plate 409 is fixedly connected to the left end of the first screw rod 408. When testing the water-based paint, first place the metal parts coated with the water-based paint on the placement plate 10, or hang them on the round rod 9, and then place the round rod 9 and the placement plate 10 in the placement grooves on the two placement racks 401, and then pass By pulling the pull rod 406 forward, the pull rod 406 slides forward and drives the sliding rod 405 to slide forward, and the sliding rod 405 drives multiple blocking rods 404 to slide forward. When the blocking rod 404 slides forward to a certain position, the blocking rod 404 can resist the top of the round rod 9 and the placement plate 10, and can improve the stability of the round rod 9 and the placement plate 10 when the placement rack 401 is transported, and prevent the round rod 9 and the placement plate 10 from falling. When the pull rod 406 slides forward to a certain distance, by rotating the fixing plate 409, the fixing plate 409 drives the first screw rod 408 to rotate. When the first screw rod 408 rotates, the threaded driving slider 407 is pressed against the placement rack 401, and the slider 407 is driven by the first screw rod 408 to press against the placement rack 401 , it is convenient to fix the sliding baffle 404, at this time, slide the placement rack 401 with the salt spray machine body 1, and at the same time, the placement rack 401 is plugged with the anti-dropping rod 403 in the salt spray machine body 1, so that the placement rack 401 slides downward along the anti-dropping rod 403, and when it slides to a certain position, the installation of the placement rack 401 is completed. The placement rack 401 is detachably connected to the salt spray machine body 1, and when one group of metal parts is tested, another group of metal parts can be placed on the round rod 9 and the placement plate 10 on another placement rack 401. After the metal part test is completed, it is only necessary to take out the placement rack 401 in the salt spray machine body 1, and install the placement rack 401 with another group of metal parts in the salt spray machine body 1 for testing, thereby improving the test efficiency.

[0046] Specifically, Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.11 As shown, the sealing structure 6 includes two sealing blocks 601 engaged in front of the salt spray machine body 1 and a connecting column 602 fixedly connected to the bottom of the sealing block 601, the bottom of the connecting column 602 is fixedly connected with a driving block 603, the driving block 603 is slidably connected to the salt spray machine body 1, and a driving groove 604 is provided on the driving block 603. A connecting block 606 is slidably connected in the salt spray machine body 1, and a driving shaft 605 is rotatably connected to the rear of the connecting block 606. The driving shaft 605 rolls with the driving groove 604, and the driving groove 604 is inclined. A second screw rod 607 is rotatably connected in the salt spray machine body 1, and the connecting block 606 is threadedly connected to the second screw rod 607. The front end of the second screw rod 607 is fixedly connected to A hand wheel 608 is connected. When the water in the sealing groove 7 needs to be discharged, the second screw rod 607 is rotated by the hand wheel 608. When the second screw rod 607 rotates, the thread drives the connecting block 606 to move backward. When the connecting block 606 moves backward, it drives the driving shaft 605 to roll and cooperate in the driving groove 604. Since the driving groove 604 is inclined, the driving block 603 drives the sealing block 601 to move upward through the connecting column 602, so that the sealing block 601 no longer seals the hole. At this time, the water in the sealing groove 7 will flow from the hole to the through hole 12, and then flow from the through hole 12 to the inside of the salt spray machine body 1. The sealing block 601 is driven by the second screw rod 607 to engage with the salt spray machine body 1 to seal the hole, so as to prevent the water source in the sealing groove 7 from flowing from the through hole 12 to the salt spray machine body 1.

[0047] When the present invention is in use and the water-based paint is tested, the metal parts coated with the water-based paint are first placed on the placement plate 10 or hung on the round rod 9, and then the round rod 9 and the placement plate 10 are placed in the placement grooves on the two placement racks 401. Then, the pull rod 406 is pulled forward, and the pull rod 406 drives the sliding rod 405 to slide forward when sliding forward, and the sliding rod 405 drives multiple blocking rods 404 to slide forward. When the blocking rod 404 slides forward to a certain position, the blocking rod 404 can resist the top of the round rod 9 and the placement plate 10, and can improve the stability of the round rod 9 and the placement plate 10 when the placement rack 401 is transported, and prevent the round rod 9 and the placement plate 10 from falling. When the pull rod 406 slides forward to a certain distance, by rotating the fixing plate 409, the fixing plate 409 drives the first screw rod 408 to rotate, and when the first screw rod 408 rotates, the thread The driving slide block 407 is pressed against the placement rack 401, and the sliding block 407 is pressed against the placement rack 401 by the first screw rod 408, so as to fix the sliding blocking rod 404. At this time, the placement rack 401 is slid with the salt spray machine body 1, and the placement rack 401 is plugged with the anti-dropping rod 403 in the salt spray machine body 1, so that the placement rack 401 slides downward along the anti-dropping rod 403. When sliding to a certain position, the installation of the placement rack 401 is completed. The placement rack 401 is detachably connected to the salt spray machine body 1, and when one group of metal parts is tested, another group of metal parts can be placed in the round rod 9 and the placement plate 10 on another placement rack 401. After the metal parts test is completed, it is only necessary to take out the placement rack 401 in the salt spray machine body 1, and install the placement rack 401 with another group of metal parts in the salt spray machine body 1 for testing, thereby improving the test efficiency.

[0048] After the placement rack 401 is installed inside the salt spray machine body 1, water can be added to the sealing groove 7. When a certain amount of water is added to the sealing groove 7, the pull plate 503 is pulled forward. When the pull plate 503 moves, it moves more smoothly through the guide column 504, and the second tension spring 505 is extended. At the same time, the pull plate 503 will drive the limit plate 501 to move forward, so that the limit plate 501 is no longer engaged with the limit groove 502 below. At this time, the connecting plate 304 and the mounting rod 303 are under the action of the first tension spring 307. When the guide rod 305 and the guide plate 306 move upward, the installation rod 303 will drive the guide rod 305 to slide with the guide plate 306. The installation rod 303 can move more smoothly through the arrangement of the guide rod 305 and the guide plate 306. At the same time, the installation rod 303 drives the rack 302 to move upward, and the rack 302 drives the gear 301 to rotate clockwise. When the gear 301 rotates, it drives the installation shaft 202 to rotate. The installation shaft 202 will rotate with the installation seat 201, and the installation shaft 202 will drive the transparent cover 203 to rotate clockwise. After the gear 301 rotates ninety degrees, the transparent cover 203 will be located in the sealing groove 7, and the limit plate 501 will move upward to align with the upper limit groove 502. The pull plate 503 will drive the limit plate 501 to engage with the upper limit groove 502 under the action of the second tension spring 505. The limit plate 501 cooperates with the two limit grooves 502 on the salt spray machine body 1 to facilitate the fixing of the rotated transparent cover 203, thereby improving the stability of the transparent cover 203. At this time, the purified water is introduced into the salt water tank, and an appropriate amount of salt powder or salt solution is added. The compressed air generated by the compressor is then sent to the spray tower 8 at the bottom of the salt water tank. The spray tower 8 will atomize the salt water into fine particles. The compressed air passes through the spray tower 8 to form a high-speed airflow in the salt water tank, bringing the salt water particles into a suspended state. With the impact of the airflow, the salt water particles evaporate in the air to form salt mist, which is sprayed by the spray tower 8 onto the surface of the test sample to form a corrosive environment, thereby testing the corrosion resistance of the water-based coating.

[0049] When it is necessary to observe the internal situation of the salt spray machine body 1 through the transparent cover 203 during the test, the rotating rod 207 can be rotated. When the rotating rod 207 rotates, the connecting shaft 204 is driven to rotate. When the connecting shaft 204 rotates, the connecting rod 205 is driven to rotate. The connecting rod 205 drives the scraper 206 to scrape off the water droplets on the inner wall of the transparent cover 203. The water droplets on the inner wall of the transparent cover 203 are scraped off by the scraper 206. When it is necessary to observe the metal parts inside the salt spray machine body 1 during the test, the observation is clearer. At the same time, when the scraper 206 finishes scraping, the knob 208 on the rotating rod 207 is rotated. The knob 208 drives the connecting ring 209 to move close to the transparent cover 203, so that the connecting ring 209 drives the rubber pad 210 to press against the transparent cover 203, thereby fixing the rotating rod 207 to prevent the rotating rod 207 from rotating.

[0050] When it is necessary to drain the water in the sealing groove 7, the second screw rod 607 is rotated by the hand wheel 608. When the second screw rod 607 rotates, the thread drives the connecting block 606 to move backward. When the connecting block 606 moves backward, it drives the driving shaft 605 to roll and cooperate in the driving groove 604. Since the driving groove 604 is inclined, the driving block 603 drives the sealing block 601 to move upward through the connecting column 602, so that the sealing block 601 no longer seals the hole. At this time, the water in the sealing groove 7 will flow from the hole to the through hole 12, and then flow from the through hole 12 to the inside of the salt spray machine body 1. The sealing block 601 is driven by the second screw rod 607 to engage with the salt spray machine body 1 to seal the hole, so as to prevent the water source in the sealing groove 7 from flowing from the through hole 12 to the salt spray machine body 1.
