Technical Field

[0001] This utility model relates to the field of environmental testing technology, specifically to an environmental testing chamber. Background Technology

[0002] An environmental test chamber is used to create a specific environmental atmosphere, and testers place the test object to be tested inside the environmental test chamber to determine the degree to which the test object can withstand the specific environmental atmosphere.

[0003] After the steel plate is produced, its corrosion resistance needs to be tested. This can be done by placing the steel plate in an environmental test chamber and then injecting an acidic solution into the chamber to immerse the steel plate in the acidic solution. However, existing environmental test chambers cannot conveniently and quickly clamp and fix the steel plate while simultaneously immersing it in an acidic solution for corrosion resistance testing. Therefore, corresponding improvements are needed to address these issues. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] according to Figures 1-4As shown, the test chamber includes a test chamber 1. An inlet pipe 11 is connected to one side of the test chamber 1 near the bottom, and a discharge pipe 12 is connected to the other side of the test chamber 1 near the bottom. Control valves are installed on the outer surfaces of both the inlet pipe 11 and the discharge pipe 12. A drain plate 13 is installed inside the test chamber 1 near one side, with several sets of evenly distributed drain holes arranged in an array. A motor 2 is installed on one side of the test chamber 1 near the top, and a rotating rod 21 is connected to the output end of the motor 2. A through hole is formed on the inner wall of one side of the test chamber 1 near the rotating rod 21. One end of the rotating rod 21 passes through a through hole and extends into the inner wall of one side of the test chamber 1. A mounting shaft 22 is installed on one end of the rotating rod 21, and a placement plate 23 is installed on both ends of the side surface of the mounting shaft 22. One end of the mounting shaft 22 is installed with a bearing and is mounted on the inner wall of one side of the test chamber 1. A placement groove 24 is opened on one side of the placement plate 23, and a fixing hole 25 is opened on both sides of the placement groove 24 inside the placement plate 23. The inner wall of the bottom end of the fixing hole 25 is tapered, and a magnet block 26 is installed on the inner wall of the bottom end of the fixing hole 25.

[0021] The placement groove 24 is equipped with a fixing mechanism 3 that clamps and fixes the steel plate. The fixing mechanism 3 includes a limiting plate 31, which is located inside the placement groove 24. The limiting plate 31 is installed on both sides of the limiting plate 31 near the top. The bottom of the mounting block 32 is equipped with a fixing rod 33. The outer diameter of the fixing rod 33 is matched with the inner diameter of the fixing hole 25. The bottom end of the fixing rod 33 extends into the inside of the fixing hole 25 and is locked in place. The bottom end of the fixing rod 33 is equipped with a tapered rod 34. The bottom end of the tapered rod 34 is attached to the top surface of the magnet block 26 and the tapered rod 34 and the magnet block 26 are attracted and fixed to each other.

[0022] In use, the user can place both ends of the steel plate into the corresponding placement groove 24, so that the bottom ends of the steel plate can overlap the inner wall of the bottom of the corresponding placement groove 24. Then, the user can place the two sets of limiting plates 31 into the corresponding placement groove 24, so that the bottom ends of the two sets of limiting plates 31 are in contact with the top of the steel plate. Simultaneously, the bottom surfaces of the two sets of mounting blocks 32 are in contact with the top surface of the corresponding placement plate 23, allowing the bottom end of the corresponding fixing rod 33 to extend into the corresponding fixing hole 25, and the corresponding tapered rod 34 to extend into the corresponding fixing hole 25 and be attracted and fixed to the corresponding magnet block 26. This fixes the corresponding limiting plate 31 and the corresponding placement plate 23, thereby clamping and securing the steel plate.

[0023] At this time, the user can open the control valve on the side surface of the feed pipe 11 to inject acidic solution into the test chamber 1. When half of the test chamber 1 is filled, the control valve on the side surface of the feed pipe 11 can be closed to stop the injection of acidic solution. After that, the motor 2 can be started. Under the operation of the motor 2, the rotating rod 21 and the mounting shaft 22 can rotate accordingly, thereby causing the two sets of placement plates 23 to rotate, which in turn drives the steel plate to rotate. When the steel plate rotates counterclockwise to 270°, it can be rotated into the interior of the acidic solution and immersed in it. At this time, the operation of the motor 2 can be stopped, so that the steel plate is in a static state. After soaking for one day, the steel plate can be rotated to its initial position by motor 2, which is directly above the drain plate 13. At this time, the acidic solution on the surface of the steel plate can be drained through the drain plate 13 and several sets of drainage holes inside the drain plate 13. At this time, the user can observe the surface of the steel plate to see if the steel plate is corroded by the acidic solution, thus enabling the steel plate to be tested for corrosion resistance. After that, the user can wipe off all the acidic solution on the surface of the steel plate and then perform the above operation in reverse order to remove the fixing mechanism 3 from the inside of the placement groove 24. Then the steel plate can be taken out from the inside of the test chamber 1. Finally, the user can open the control valve on the side surface of the discharge pipe 12 to discharge the acidic solution inside the test chamber 1.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
