Description

Technical Field

[0001] This utility model relates to the field of acidic salt spray testing, specifically an acidic salt spray test chamber. Background Technology

[0002] Acidic salt spray testing is a standardized testing method that simulates the acidic corrosion environment of the ocean or industry. It is mainly used to evaluate the corrosion resistance of materials, coatings, metal components and electronic components. Its core principle is to simulate acidic salt spray corrosion conditions through artificial climate environment to accelerate the material corrosion process, thereby predicting the durability of products in actual use in a short period of time.

[0003] In existing technologies, acidic salt spray testing is a common procedure for testing the corrosion resistance of industrial objects. It primarily involves acidifying a sodium chloride solution to form an acidic liquid, then placing the sample inside an acidic salt spray test chamber. The acidic salt spray is then sprayed through nozzles for an extended period, and the corrosion status of the sample is observed afterward. Typically, to obtain more experimental data at once, multiple samples are placed inside the test chamber. By conducting a unified test on multiple samples, the corrosion resistance of that type of sample can be effectively assessed. Generally, when testing multiple samples… When conducting a unified test on multiple samples, the samples are placed on a test rack and slightly tilted to ensure that each sample surface is exposed to salt spray corrosion while minimizing liquid accumulation. However, when staff place multiple samples on the test rack and adjust the tilt angle, various factors such as hand shaking or trembling may cause the tilt angles of the multiple test samples to differ. Even without any unexpected events, there may still be some angular error when tilting the samples, resulting in different tilt angles for multiple samples and thus affecting the accuracy of the data obtained during the acid salt spray test. Utility Model Content

[0004] To address the shortcomings of existing technologies, when staff place multiple samples on the test rack and adjust the tilt angle, various factors such as hand shaking or trembling may cause the tilt angles of the multiple test samples to be different. Even without any accidents, there may still be some angular errors when tilting the samples, resulting in different tilt angles for multiple samples, which in turn affects the accuracy of the data obtained during acidic salt spray testing. This utility model proposes an acidic salt spray test chamber.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an acidic salt spray test chamber, including a test chamber body, a connecting pipe fixedly connected to the inner cavity of the test chamber body, an atomizing pump body fixedly connected to the surface of the connecting pipe, an atomizing nozzle fixedly connected to one end of the connecting pipe, an installation plate provided in the inner cavity of the test chamber body, an installation frame fixedly connected to the top of the installation plate, and an tilting mechanism provided on the top of the installation plate. The tilting mechanism includes multiple rotating rods, each with its surface rotatably connected to the inner cavity of the mounting frame. A connecting block is fixedly connected to one end of each rotating rod, and a placement plate is fixedly connected to one side of each connecting block. A moving rod is fixedly connected to the other side of each connecting block. A connecting plate is rotatably connected to the surface of each moving rod. An adjustment component is provided on one side of the connecting plate, and a driving component and a convenient component are provided at the bottom of the placement plate.

[0006] Preferably, the adjustment assembly includes a fixed rod, one side of which is fixedly connected to one side of a connecting plate. A movable plate is rotatably connected to the surface of the fixed rod. An installation rod is rotatably connected to the inner cavity of the movable plate. An installation block is fixedly connected to the surface of the installation rod. A rotating block is fixedly connected to one side of the installation block. A rotating shaft is rotatably connected to one side of the mounting frame. The inner cavity of the rotating block is fixedly connected to the surface of the rotating shaft.

[0007] Preferably, the drive assembly includes a fixed frame, one side of which is fixedly connected to one side of the mounting frame. A rotating shaft is fixedly connected to one side of the fixed frame, a worm is fixedly connected to the surface of the rotating shaft, and a worm wheel is fixedly connected to the surface of the rotating block. The surface of the worm wheel meshes with the surface of the worm.

[0008] Preferably, the convenient component includes a rotating grip, the surface of which is rotatably connected to the inner cavity of the fixed frame, a driving bevel gear fixedly connected to the surface of the rotating grip, and a driven bevel gear fixedly connected to the surface of the rotating shaft, wherein the teeth of the driven bevel gear mesh with the teeth of the driving bevel gear.

[0009] Preferably, each of the multiple placement plates is fixedly connected to a limiting frame on its top, and each of the multiple limiting frames has hollow holes on both sides.

[0012] The advantages of this utility model are: This invention utilizes a rotating handle to smoothly drive a drive assembly through the meshing of an active and driven bevel gear. The drive assembly then rotates a rotating shaft, allowing the moving rod to pull or push the connecting plate, thus enabling multiple connecting blocks to rotate multiple placement plates around the center of the rotating handle. This allows operators to uniformly tilt multiple samples at once when adjusting their angles, reducing accidental tilting when tilting samples individually. By minimizing angle errors between samples, the accuracy of acid salt spray testing is increased. This invention solves the problem that when adjusting the tilt angle of multiple samples on the test rack, hand movements or tremors can cause inconsistencies, even without unexpected events, leading to angular errors and affecting the accuracy of data obtained from acid salt spray testing.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an acidic salt spray test chamber. (Refer to...) Figure 1 and Figure 5 An acidic salt spray test chamber includes a test chamber body 1, a connecting pipe 2 fixedly connected to the inner cavity of the test chamber body 1, an atomizing pump body 3 fixedly connected to the surface of the connecting pipe 2, an atomizing nozzle 4 fixedly connected to one end of the connecting pipe 2, an installation plate 5 provided in the inner cavity of the test chamber body 1, an installation bracket 6 fixedly connected to the top of the installation plate 5, and an tilting mechanism 7 provided on the top of the installation plate 5. The tilting mechanism 7 includes multiple rotating rods 701. The surfaces of the multiple rotating rods 701 are rotatably connected to the inner cavity of the mounting frame 6. One end of each of the multiple rotating rods 701 is fixedly connected to a connecting block 702. One side of each of the multiple connecting blocks 702 is fixedly connected to a placement plate 703. The other side of each of the multiple connecting blocks 702 is fixedly connected to a moving rod 704. The surfaces of the multiple moving rods 704 are rotatably connected to a connecting plate 705. One side of the connecting plate 705 is provided with an adjustment component 706. The bottom of the placement plate 703 is provided with a drive component 707 and a convenient component 708.

[0018] The test chamber 1 can be used to install and fix the atomizing pump body 3 and the atomizing nozzle 4 through the connecting pipe 2. One end of the connecting pipe 2 is used to connect and install the atomizing nozzle 4, and the other end is connected to an external storage box for storing acidic salt spray. The atomizing pump body 3, through its own operation, pumps the acidic salt spray through the connecting pipe 2 into the atomizing nozzle 4, and then sprays the acidic salt spray out through the atomizing nozzle 4 to test the sample. The test chamber 1, connecting pipe 2, atomizing pump body 3, atomizing nozzle 4, and external storage box for storing acidic salt spray are all existing technologies in this field, and therefore will not be described in detail here. The mounting plate 5 can be connected to the rotating rod 701 via the mounting bracket 6, and the rotating rod 701 can be used to install and fix the placement plate 703 via the connecting block 702. The top of the placement plate 703 can be used to place the sample to be tested. At the same time, multiple connecting blocks 702 can be connected to the connecting plate 705 via the moving rod 704. This allows the driving component 707 to smoothly drive multiple placement plates 703 to rotate and tilt in the same direction synchronously via the adjusting component 706 when it is operating, thereby achieving uniformity in the adjustment of the sample angle and increasing the accuracy when conducting unified tests on multiple samples.

[0019] Reference Figure 5 The adjusting assembly 706 includes a fixed rod 7061, one side of which is fixedly connected to one side of a connecting plate 705. A movable plate 7062 is rotatably connected to the surface of the fixed rod 7061. A mounting rod 7063 is rotatably connected to the inner cavity of the movable plate 7062. A mounting block 7064 is fixedly connected to the surface of the mounting rod 7063. A rotating block 7065 is fixedly connected to one side of the mounting block 7064. A rotating shaft 7066 is rotatably connected to one side of the mounting bracket 6. The inner cavity of the rotating block 7065 is fixedly connected to the surface of the rotating shaft 7066. The rotating shaft 7066 can connect to the mounting block 7064 via the rotating block 7065. The movable plate 706... 2. Through its connection with the fixed rod 7061 and the mounting rod 7063, the rotating block 7065 can smoothly pull the moving plate 7062 to tilt and move when it rotates. By utilizing the connection between the fixed rod 7061 and the connecting plate 705, the connecting plate 705 can be smoothly pulled or pushed, allowing the connecting plate 705 to push or pull the moving rod 704, thereby pushing or pulling the connecting block 702. This allows multiple connecting blocks 702 to smoothly rotate and tilt around the center of the rotating rod 701, thereby tilting the placement plate 703 and the sample on top of the placement plate 703.

[0020] Reference Figure 5The drive assembly 707 includes a fixing frame 7072, one side of which is fixedly connected to one side of the mounting frame 6. A rotating shaft 7074 is fixedly connected to one side of the fixing frame 7072. A worm gear 7073 is fixedly connected to the surface of the rotating shaft 7074. A worm wheel 7071 is fixedly connected to the surface of the rotating block 7065. The surface of the worm wheel 7071 meshes with the surface of the worm gear 7073. The mounting frame 6 can connect the rotating shaft 7074 through the fixing frame 7072, and the rotating shaft 7074 can be used for mounting and fixing. The worm gear 7073 and the worm wheel 7071 mounted on the surface of the rotating shaft 7066 can mesh with the worm gear 7073, so that when the worm gear 7073 rotates, it can smoothly drive the rotating block 7065 and the rotating shaft 7066 to rotate, thereby realizing the rotation of the connecting block 702. It can not only realize the rotation drive of the rotating shaft 7066, but also increase the stability of the connecting block 702 and the placement plate 703 after rotating to a certain angle through the self-locking between the worm gear 7073 and the worm wheel 7071.

[0021] Reference Figure 5 The convenient component 708 includes a rotating grip 7081, the surface of which is rotatably connected to the inner cavity of a fixed frame 7072. A driving bevel gear 7082 is fixedly connected to the surface of the rotating grip 7081, and a driven bevel gear 7083 is fixedly connected to the surface of a rotating shaft 7074. The teeth of the driven bevel gear 7083 mesh with the teeth of the driving bevel gear 7082. The fixed frame 7072 can be connected to the driving bevel gear 7082 by rotating the grip 7081, while the rotating shaft 7084... 74 can install and fix the driven bevel gear 7083, which allows the operator to rotate the worm 7073 by rotating the rotating handle 7081, thereby driving the driving bevel gear 7082 to rotate. The meshing between the driving bevel gear 7082 and the driven bevel gear 7083 changes the direction of the force when the operator rotates the rotating handle 7081, thus achieving the rotation of the worm 7073. This makes it more convenient for the operator to rotate the rotating shaft 7066.

[0022] Reference Figure 2 and Figure 3Each of the multiple placement plates 703 has a limiting frame 8 fixedly connected to its top. Hollow holes 9 are provided on both sides of the multiple limiting frames 8. A collection box 10 is provided on the top of the mounting plate 5. A fixing plate 16 is fixedly connected to the top of the limiting frame 8. An elastic gripper 17 is fixedly connected to one side of the fixing plate 16. The limiting frame 8 can be installed and fixed by the fixing plate 16. The elastic gripper 17 can hold the sample that needs to be tested for acidic salt spray, so that the sample can be suspended in the air, thereby improving the effect of the sample during the test and increasing the contact area between the sample and the acidic salt spray. At the same time, the opening of the hollow holes 9 makes it difficult for liquid to accumulate in the limiting frame 8 during use. The collection box 10 can collect some of the acidic salt liquid that drips through the hollow holes 9, so that the staff can handle the acidic salt liquid later.

[0023] Reference Figure 1 and Figure 2 An alarm 11 and a PLC controller 12 are fixedly connected to the top of the test chamber 1. A temperature monitor 13 is also fixedly connected to the top of the test chamber 1, and a temperature monitoring probe 14 is fixedly connected to the bottom of the temperature monitor 13. One end of the temperature monitoring probe 14 penetrates through the top of the test chamber 1. The temperature monitor 13 can monitor the internal temperature of the test chamber 1 through the temperature monitoring probe 14, thereby ensuring that the internal temperature of the test chamber 1 does not deviate significantly. If the internal temperature of the test chamber 1 is abnormal, the temperature monitor 13 can activate the alarm 11 through the PLC controller 12, causing the alarm 11 to sound an alarm, thus alerting the personnel. Simultaneously, the temperature monitoring probe 14 collects the temperature inside the test chamber 1 in real time and transmits it to the temperature monitor 13. The temperature monitor 13 transmits the data to the PLC controller 12. When the temperature exceeds the set range, the PLC controller 12 triggers the alarm 11 to issue an audible and visual alarm. Furthermore, the alarm 11, PLC controller 12, temperature monitor 13, and temperature monitoring probe 14 can all be selected from different models according to the actual situation. For example, the alarm 11 can be an ABB-PA80, the PLC controller 12 can be a Siemens S7-1200, the temperature monitor 13 can be a Yokogawa YT-2000, and the temperature monitoring probe 14 can be an OMEGA-PT100.

[0024] Reference Figure 4 Each of the multiple rotating rods 701 has a reinforcing ring 15 fixedly connected to its surface. One side of each reinforcing ring 15 is rotatably connected to one side of the mounting frame 6. The reinforcing ring 15 can strengthen and limit the rotating rod 701 through its connection with the rotating rod 701 and the mounting frame 6, so that the rotating rod 701 has sufficient stability when rotating and is not prone to shaking, tilting or swinging. This increases the stability of the placement plate 703 when it tilts the sample.

[0025] Working Principle: When using this device, the operator first places multiple samples to be tested on top of multiple placement plates 703 and inside the limiting frame 8. Then, the operator manually rotates the rotating handle 7081. Rotating the handle 7081 drives the driving bevel gear 7082 to rotate. The meshing of the driving bevel gear 7082 and the driven bevel gear 7083 drives the rotating shaft 7074 and the worm gear 7073 on its surface to rotate. The rotation of the worm gear 7073 drives the worm wheel 7071 to rotate, thereby synchronously rotating the rotating shaft 7066, rotating block 7065, mounting block 7064, and mounting rod 7063 around the center of the rotating shaft 7066. When the mounting rod 7063 rotates, it can pull or push the moving plate 7062, which in turn allows the moving plate 7062 to tilt and move the connecting plate 705 via the fixed rod 7061. In turn, the moving rod 704 pulls or pushes the connecting block 702, so that multiple connecting blocks 702 can drive the placement plate 703 to rotate and tilt around the center of the rotating rod 701. This achieves uniform tilting and angle adjustment for multiple samples. Afterward, the staff can close the test chamber 1 and pump the corrosive medium in the external acidic salt spray storage box into the atomizing nozzle 4 through the connecting pipe 2 via the operation of the atomizing pump 3. The medium is then sprayed through the atomizing nozzle 4 to test the corrosion resistance of the samples.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
