Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixing devices, in particular to an epoxy resin composition sample fixing device. Background Art
[0002] Ultrasonic testing is a non-destructive testing method that can detect the internal structure of the sample without destroying it. Therefore, it is suitable for testing composite materials such as epoxy resin to help detect possible defects in epoxy resin compositions, such as bubbles, cracks, inclusions, etc., to ensure that their quality meets the requirements.
[0003] In the prior art, the method of fixing the samples for ultrasonic scanning test is to use double-sided tape, that is, to stick multiple samples on the test substrate by double-sided tape, or to fix multiple samples in a frame plate, and then use double-sided tape to stick the frame plate on the test substrate. However, the service life of double-sided tape in the medium pure water is extremely short, and it needs to be replaced frequently. When replacing, the double-sided tape is easy to fall off into the pure water, causing pollution to the equipment, and reducing the use cycle of pure water and increasing the difficulty of cleaning. In addition, frequent use of double-sided tape will also affect the sample (such as causing glue residue, bending or breaking on the sample surface during the pasting and removal process), affecting the subsequent testing, retention and recovery of samples.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1 , Figure 5 As shown, the utility model provides an epoxy resin composition sample fixing device, which is suitable for a frame plate 3, on which a plurality of samples are fixed, and a plurality of equidistantly distributed positioning holes 31 are provided on the side of the frame plate 3.
[0025] The epoxy resin composition sample fixing device comprises: a substrate 1, a plurality of cells are arranged on the substrate 1, a frame plate 3 is arranged on the cells, a cutting hole is opened on the substrate 1, the substrate 1 is divided into a plurality of cells by the cutting holes, and the area of the frame plate 3 is larger than the area of a single cell.
[0026] Among them, Figure 1-Figure 2 As shown, the cutting hole is a long strip hole that vertically penetrates the substrate 1, and the cutting hole includes a transverse cutting hole 11 and a longitudinal cutting hole 12. The midpoint and end point of the transverse cutting hole 11 do not penetrate the substrate 1, and the end point of the longitudinal cutting hole 12 does not penetrate the substrate 1, so as to improve the overall strength of the substrate 1.
[0027] like Figure 1-Figure 3 As shown, a movable fixing member is arranged between the cells, and the fixing member is used to fix the sample. Preferably, the fixing member is a nail buckle 2, and the sample is fixed by the nail buckle 2.
[0028] Specifically, a plurality of nail buckles 2 are provided, and the nail buckles 2 include a fixing nail 21, which is provided in the cutting hole. The fixing nail 21 is detachably connected with a lock buckle 22, and the lock buckle 22 is provided at the bottom of the base plate 1. The frame plate 3 can be fixed on the base plate 1 by cooperating with the fixing nail 21 and the lock buckle 22.
[0029] In this embodiment, if Figure 4-Figure 5 As shown, several samples to be tested (epoxy resin composition samples) are placed on the frame plate 3, and the position of the nail buckle 2 is adjusted according to the size of the frame plate 3. After the position is adjusted, the fixing nail 21 is passed through the positioning hole 31, and the fixing nail 21 is locked with the lock buckle 22 at the bottom of the substrate 1, so that the frame plate 3 is fixed on the substrate 1. For subsequent ultrasonic scanning tests, when the frame plate 3 needs to be removed, the lock buckle 22 and the fixing nail 21 are removed, and the frame plate 3 carrying the sample is removed. In this process, there is no need to use double-sided tape for fixing, thereby avoiding the debris generated in the tearing process of the double-sided tape from contaminating the pure water and the equipment, preventing the sample from being damaged due to the replacement of the double-sided tape, and avoiding the impact of the test results due to the destruction of the internal structure of the sample.

When the frame plate 3 needs to be removed, remove the lock buckle 22 and the fixing nail 21, and move the frame plate 3 carrying the sample away.
