Description

Technical Field

[0001] This utility model relates to the field of engineering plastics testing technology, and in particular to a hanger for testing corrosion of engineering plastics. Background Technology

[0002] Corrosion testing of engineering plastics is used to evaluate their corrosion resistance in specific chemical environments, ensuring their reliability and safety in practical applications. During testing, a sample plate is placed in a corrosion testing tank and completely immersed in the corrosive solution. After testing, the sample plate is removed, weighed, and its corrosion condition observed. Currently, corrosion testing involves directly placing the sample plate in the corrosion tank, using pressure bars or other components to prevent it from floating and thus avoiding contact between the corrosive solution and the upper part of the sample plate. However, this method has drawbacks: the large contact area between the pressure bar and the sample plate affects the test results, and it also presents the problem of inconvenient sample removal. Utility Model Content

[0003] This utility model provides a hanging rack for corrosion detection of engineering plastics to overcome the shortcomings of the prior art. It facilitates the placement of sample plates so that the sample plates are immersed in the corrosion solution and is easy to remove, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A bracket for corrosion detection of engineering plastics includes a rectangular frame, with lower plates welded to the four corners of the rectangular frame, vertical rods welded to the lower plates, a lower support plate welded to the lower end of the vertical rods, a rotating pressure plate fitted onto the upper end of the vertical rods, a spring fitted onto the upper end of the vertical rods, and a limit nut connected to the upper end of the vertical rods via a thread, with the spring located between the limit nut and the rotating pressure plate.

[0006] Furthermore, a support rod is welded to the upper inner wall of the lower support plate, and the upper end of the support rod has a hemispherical structure.

[0007] Furthermore, a pressure rod is welded to the lower inner wall of the rotating pressure plate, and the lower end of the pressure rod has a hemispherical structure.

[0008] Furthermore, a lever is welded onto the rotating pressure plate.

[0009] Furthermore, a partition plate is welded onto the vertical rod, and a rotating top plate is provided on the lower side of the partition plate. A rotating vertical rod is welded to the outer end of the rotating top plate. The rotating top plate is rotatably mounted on the vertical rod, and a lower nut is provided on the lower side of the rotating top plate. The lower nut is threadedly connected to the vertical rod, and the lower nut and the partition plate are located between the rotating pressure plate and the lower support plate.

[0010] Furthermore, a sleeve is welded to the lower wall of the rectangular frame, a locking nut is threaded onto the sleeve, an L-shaped plate is fitted onto the sleeve, an inner rod is welded to the inner wall of the vertical section of the L-shaped plate, an insertion hole is opened at the lower end of the sleeve, the inner rod passes through the insertion hole, and a connection hole is opened at the upper end of the vertical rod.

[0011] When two hangers are connected, the inner rod at the upper end is inserted into the connecting hole at the lower end, and the upper end of the vertical rod passes through the sleeve.

[0012] Furthermore, an L-shaped hanging rod is inserted through the connecting hole, and a crossbar is formed at the upper end of the L-shaped hanging rod on the same side.

[0013] The advantages of the above technical solution are:

[0014] This invention uses support rods and pressure rods to fix the sample plate, and the gravity provided by the bracket prevents the sample plate from floating due to buoyancy, thus immersing it in the corrosive solution. Furthermore, since the sample plate is fixed to the bracket, it is easy to remove after testing. In addition, rotating the top plate acts on the side wall of the sample plate to further limit its position. Simultaneously, the bracket can be stacked and connected for easy corrosion testing of multiple sample plates. Finally, the L-shaped hanging rod and crossbar facilitate the removal of the sample plate. Attached Figure Description

[0018] Figure 3 A three-dimensional structure of one embodiment is shown. Figure 2 .

[0019] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0020] like Figures 1-4As shown, a bracket for corrosion detection of engineering plastics includes a rectangular frame 1. Lower plates 2 are welded to the four corners of the rectangular frame 1. Vertical rods 20 are welded to the lower plates 2. Lower support plates 21 are welded to the lower ends of the vertical rods 20. A rotating pressure plate 23 is fitted onto the upper end of the vertical rods 20. A lever 25 is welded onto the rotating pressure plate 23. A spring 27 is fitted onto the upper end of the vertical rods 20. A limit nut 26 is threadedly connected to the upper end of the vertical rods 20. The spring 27 is located between the limit nut 26 and the rotating pressure plate 23.

[0021] This embodiment uses the corrosion detection of a single sample plate as an example. During the test, the operator places the sample plate on the lower support plate 21, then pulls and rotates the rotating pressure plate 23 upwards so that the rotating pressure plate 23 is positioned above the sample plate. The rotating pressure plate 23 then fixes the sample plate under the elastic force of the spring 27. The hanger and the sample plate on it are then placed in the corrosion tank for corrosion detection. During the test, the sample plate is immersed in the corrosion solution due to the hanger and its own weight, ensuring the accuracy of the corrosion detection. After the test is completed, the sample plate is removed from the corrosion tank.

[0022] In some embodiments, a support rod 22 is welded to the upper inner wall of the lower support plate 21. The upper end of the support rod 22 has a hemispherical structure. The design of the support rod 22 and the hemispherical structure reduces the contact area between the support rod 22 and the sample plate, thereby improving the accuracy of corrosion detection.

[0023] In some embodiments, a pressure rod 24 is welded to the lower inner wall of the rotating pressure plate 23. The lower end of the pressure rod 24 has a hemispherical structure and acts on the upper wall of the sample plate to reduce the contact area between the pressure rod and the upper wall of the sample plate.

[0024] In some embodiments, a partition plate 28 is welded onto the vertical rod 20, a rotating top plate 29 is provided on the lower side of the partition plate 28, a rotating vertical rod 31 is welded to the outer end of the rotating top plate 29, the rotating top plate 29 is rotatably mounted on the vertical rod 20, a lower nut 30 is provided on the lower side of the rotating top plate 29, the lower nut 30 is threadedly connected to the vertical rod 20, and the lower nut 30 and the partition plate 28 are located between the rotating pressure plate 23 and the lower support plate 21.

[0025] After the sample plate is placed, to prevent it from moving, the rotating top plate 29 can be rotated so that the inner end of the rotating top plate 29 acts on the side wall of the sample plate to fix the sample plate.

[0026] In some embodiments, a sleeve 34 is welded to the lower wall of the rectangular frame 1, and a locking nut 35 is threaded onto the sleeve 34. An L-shaped plate 36 is fitted onto the sleeve 34, and an inner insert rod 38 is welded to the inner wall of the vertical section of the L-shaped plate 36. An insertion hole 39 is opened at the lower end of the sleeve 34, and the inner insert rod 38 passes through the insertion hole 39. A connecting hole is opened at the upper end of the vertical rod 20. When two hangers are connected, the inner insert rod 38 at the upper end is inserted into the connecting hole at the lower end, and the upper end of the vertical rod 20 passes through the sleeve 34.

[0027] When performing corrosion testing on multiple sample plates, the operator fixes and clamps each sample plate separately, and then places one sample plate and the rectangular frame 1 in a stacked manner. During placement, the sleeve 34 on the upper rectangular frame 1 is placed on the upper end of the vertical rod 20 on the lower layer, and then the inner insertion rod 38 is moved inward and inserted into the insertion hole 39 and the connection hole, and then the corrosion testing operation on multiple sample plates is performed.

[0028] In some embodiments, an L-shaped hanging rod 32 is inserted through the connecting hole, and a crossbar 33 is formed at the upper end of the L-shaped hanging rod 32 located on the same side.

[0029] When removing the sample plate, the L-shaped hanging rod 32 can be inserted into the connecting hole, and then the crossbar 33 can be held upwards to remove the sample plate from the etching solution.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
