Description

Technical Field

[0001] This utility model relates to the field of post-processing technology for engineering plastics testing, and in particular to a support frame for cleaning engineering plastics. Background Technology

[0002] Corrosion testing of engineering plastics is an important part of engineering plastic testing. After corrosion testing, in order to facilitate the observation of the corrosion status of the engineering plastics and to avoid contamination of the tester and other components or safety accidents caused by the corrosive liquid, cleaning is required after corrosion testing. Currently, the samples are placed directly in the cleaning tank for cleaning. If multiple samples need to be cleaned, they are prone to collisions, which can damage the corrosion morphology of the samples. At the same time, if water is used for cleaning, the cleaning effect is poor, and subsequent cleaning is required, thus wasting water resources. Utility Model Content

[0003] This utility model provides a support frame for cleaning engineering plastics, which overcomes the shortcomings of the prior art and solves the problem that the corrosion morphology of the sample is easily damaged during cleaning, and has strong practicality.

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

[0005] A support frame for cleaning engineering plastics includes a rectangular base frame. Multiple pairs of backing plates are welded to the upper wall of the rectangular base frame along its length. Each backing plate has an inner shaft rotatably mounted on one side, and the inner shaft is rotatably mounted on the rectangular base frame. A clamping wheel is eccentrically mounted at the upper end of the inner shaft, and a swing arm is mounted at the lower end of the inner shaft. A slotted hole is opened at the outer end of the swing arm, and a moving rod passes through the slotted hole. The upper end of the moving rod on the same side is threadedly connected to a moving arm. One side of each pair of backing plates contacts one side of the sample, while the other side of the sample is in close contact with the clamping wheel. Thus, when the clamping wheel rotates, its circumference acts on the sample, thereby achieving the requirement of fixing the sample. Furthermore, gaps exist between the fixed samples to prevent damage to the sample's corrosion morphology due to collisions or other reasons. When using this support frame for sample cleaning, the support frame with the sample is placed in a cleaning tank, and then cleaned by rinsing. Rinsing avoids damage to the corrosion morphology and facilitates a quick cleaning operation.

[0006] Furthermore, in order to enable the clamping wheels to rotate synchronously to fix the lower end of the sample, a horizontal plate is welded to the outer end of the moving arm, a convex plate is welded to the horizontal plate, a pair of guide rods are inserted through the convex plate, the outer end of the guide rods is provided with an end cap, and the inner end of the guide rods is connected to an inner plate by threads. The inner plate is welded to one end of the rectangular base frame, and an outer top spring is sleeved on the guide rod. The outer top spring is located between the inner plate and the convex plate. The outer top spring can push the convex plate to move outward, thereby facilitating the removal of the fixation of the sample.

[0007] Furthermore, in order to ensure the stability of the sample after fixation, it is necessary to lock the rotation state of the clamping wheel. Therefore, a clamping plate is provided on the inner and outer sides of the convex plate. A T-shaped plate is welded to the upper end of the clamping plate, and a pair of pull-down pins are welded to the inner end of the T-shaped plate. The pull-down pins pass through one end of the rectangular bottom frame.

[0008] Furthermore, during the cleaning process, in order to prevent the pull pin from moving upward due to external force, a limiting plate is provided at the lower end of the pull pin, and a lower top spring is sleeved on the pull pin, with the lower top spring located between the rectangular bottom frame and the limiting plate.

[0009] Furthermore, in order to facilitate the limiting of the upper end of the sample and to place the upper end of the support frame on the upper end of the cleaning tank so that the lower end of the support frame is separated from the lower end of the cleaning tank to prevent the cleaning liquid from corroding the lower end of the sample again and to facilitate the discharge of the cleaning liquid, upper extension rods are welded at the four corners of the rectangular base frame. A concave head is welded to the upper end of the upper extension rod. The upper end of the concave head is connected to a rotating rod through a hinge shaft. The upper end of the rotating rod is provided with an upper cap. A lower pressure strip is sleeved on the upper end of the rotating rod on the same side. A lower pressure spring is sleeved on the upper end of the rotating rod. The lower pressure spring is located between the upper cap and the lower pressure strip.

[0010] Furthermore, to facilitate the transfer of the support frame, a lifting handle is welded onto the lower pressure bar.

[0011] The advantages of the above technical solution are:

[0012] This invention can prevent the impact of mutual collision between samples on the corrosion morphology during sample cleaning after corrosion, and also facilitates sample cleaning operations. Attached Figure Description

[0018] Figure 5 A magnified view of point C is shown. Detailed Implementation

[0019] like Figures 1-5 As shown, a support frame for cleaning engineering plastics includes a rectangular base frame 1. Multiple pairs of backing plates 2 are welded to the upper wall of the rectangular base frame 1 along its length. Each backing plate 2 has an inner shaft rotatably mounted on one side. The inner shaft is rotatably mounted on the rectangular base frame 1. A pressure wheel 20 is eccentrically mounted at the upper end of the inner shaft, and a swing arm 21 is mounted at the lower end of the inner shaft. A strip-shaped hole 22 is opened at the outer end of the swing arm 21, and a moving rod 23 passes through the strip-shaped hole 22. A moving arm 24 is threadedly connected to the upper end of the moving rod 23 on the same side. A horizontal plate 25 is welded to the outer end of the moving arm 24, and a protruding plate 26 is welded to the horizontal plate 25. A pair of guide rods 27 pass through the protruding plate 26, and an end cap 28 is provided at the outer end of the guide rods 27. An inner plate 29 is threadedly connected to the inner end of the guide rods 27, and the inner plate 29 is welded to one end of the rectangular base frame 1.

[0020] In this embodiment, when cleaning the corroded sample, the operator places multiple samples between each pair of clamping rollers 20 and the backing plate 2. After the samples are placed, the operator pushes the horizontal plate 25 inward, so that the horizontal plate 25 drives the moving arm 24 to move. As the moving arm moves, the moving rod 23 on it acts on the slot 22, thereby causing the swing arm 21 to rotate. The rotation of the swing arm 21 will drive the clamping rollers 20 to rotate. In this way, the peripheral side of the far end of the clamping roller 20 is pressed against one side of the sample. Then the support frame is placed in the cleaning tank, and the sample is cleaned by spraying. After cleaning, the sample is taken out.

[0021] In some embodiments, an outer top spring 30 is sleeved on the guide rod 27 of an engineering plastic cleaning support frame. The outer top spring 30 is located between the inner plate 29 and the convex plate 26. A clamping plate 33 is provided on the inner and outer sides of the convex plate 26. A T-shaped plate 32 is welded to the upper end of the clamping plate 33. A pair of pull-down pins 31 are welded to the inner end of the T-shaped plate 32. The pull-down pins 31 pass through one end of the rectangular bottom frame 1. A limiting plate 35 is provided at the lower end of the pull-down pins 31. A lower top spring 34 is sleeved on the pull-down pins 31. The lower top spring 34 is located between the rectangular bottom frame 1 and the limiting plate 35.

[0022] In this embodiment, when the lower end of the sample is fixed, the operator moves the horizontal plate 25 inward to the clamping plate 33, first pulls the clamping plate 33 upward, and compresses the lower top spring 34 until the convex plate 26 moves between the clamping plates 33. Then, the clamping plate 33 limits the convex plate 26 under the action of the lower top spring 34, thus ensuring the stability of the sample fixation.

[0023] In some embodiments, an upper extension rod 36 is welded to the four corners of a rectangular base frame 1 on an engineering plastic cleaning support frame. A concave head 37 is welded to the upper end of the upper extension rod 36. A rotating rod 38 is connected to the upper end of the concave head 37 via a hinge shaft. An upper cap 40 is provided at the upper end of the rotating rod 38. A lower pressure strip 39 is sleeved on the upper end of the rotating rod 38 on the same side. A lower pressure spring 41 is sleeved on the upper end of the rotating rod 38. The lower pressure spring 41 is located between the upper cap 40 and the lower pressure strip 39. A lifting handle is welded to the lower pressure strip 39.

[0024] In this embodiment, after the sample is placed, the lower pressure bar 39 is pulled upward, and the lower pressure spring 41 is compressed. Then, the lower pressure bar 39 is rotated upward so that it is located at the upper end of the sample. Then, the pulling force on the lower pressure bar 39 is released. Subsequently, the lower pressure bar 39 will act on the upper end of the sample under the action of the lower pressure spring 41. Then, the two ends of the lower pressure bar 39 are placed on the upper end of the cleaning tank, and the sample cleaning operation is performed.

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.
