[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] The following is a reference appendix. Figures 1-5 The present invention describes a multifunctional magnetic suction fixture 100 for positioning an in-situ indentation testing instrument according to an embodiment of the present invention. The multifunctional magnetic suction fixture 100 can be used to fix a portable in-situ indentation testing instrument to the surface of different types of test materials 300 to achieve indentation testing.

[0031] like Figure 1 As shown, the multifunctional magnetic suction fixture 100 for positioning an in-situ pressing detection instrument according to an embodiment of the present utility model includes a fixed plate assembly, multiple adjusting plates 20, multiple fasteners 23, and multiple magnetic suction components 30.

[0032] The in-situ indentation testing instrument can be mounted on the fixed plate assembly, and the fixed plate assembly has a gap for the in-situ indentation testing instrument to contact the material 300 under test during testing. Connecting parts 111 are provided on opposite sides of the fixed plate assembly, such as... Figure 1 In the middle, the left and right sides of the fixing plate assembly are symmetrically provided with connecting parts 111;

[0033] The adjusting plates 20 are also symmetrically arranged on both sides of the fixed plate assembly, such as... Figure 1 In the middle, the adjusting plate 20 is located on the left and right sides of the fixed plate assembly to ensure that the in-situ pressing detection instrument is subjected to balanced force under its own weight. The adjusting plate 20 is provided with a coupling part 221, which corresponds to the position of the connecting part 111. The fastener 23 is detachably provided at the coupling part 221 and the connecting part 111, so that the adjusting plate 20 can pivot relative to the fixed component assembly. After the working angle between the adjusting plate 20 and the fixed plate assembly is continuously adjusted, the fastener 23 is used to fasten the connection to ensure that the working angle is fixed and to avoid inaccurate detection results due to the unstable working angle of the in-situ pressing detection instrument during operation.

[0034] Magnetic components 30 are respectively disposed at the bottom of the adjustment plate 20 and correspond to the adjustment plate 20, for example, as Figure 1 In the middle, the bottom of the adjustment plate 20 on the left and the adjustment plate 20 on the right are respectively provided with magnetic suction components 30. Each magnetic suction component 30 includes a magnetic suction base connected to the adjustment plate 20 and a magnetic suction element installed on the magnetic suction base. The magnetic suction fixture achieves a tight connection with the material to be tested 300 through the magnetic suction element. Compared with traditional mechanical fixtures, the installation and connection process is simplified.

[0035] Therefore, the multifunctional magnetic fixture 100 for positioning the in-situ pressing test instrument according to the present utility model embodiment, through the setting of the adjusting plate 20 and the fixed plate assembly, allows the included angle between the adjusting plate 20 and the fixed plate 10 assembly to be continuously adjusted, ensuring that the test instrument can be closely adapted to the surface of the test material 300 of different shapes. Compared with traditional fixtures, it increases adaptability and is convenient to install and disassemble with high efficiency.

[0036] According to some embodiments of this utility model, such as Figure 1-5 As shown, the fixing plate assembly includes two spaced-apart and symmetrically arranged fixing plates 10, spaced apart by a preset gap 112. The two fixing plates 10 are pivotally connected to their corresponding adjusting plates 20 via fasteners 23, coupling portions 221, and connecting portions 111, for example, as... Figure 1In the middle, the fixing plate assembly includes a left fixing plate 10 located on the left and a right fixing plate 10 located on the right. The connecting part 111 of the left fixing plate 10 is correspondingly coupled to the coupling part 221 between the left adjusting plate 20 and the right adjusting plate 20. The degree of contact between the in-situ pressing test instrument and the surface of the material to be tested 300 is determined by adjusting the angle between the left fixing plate 10 and the left adjusting plate 20 and the right fixing plate 10 and the right adjusting plate 20. Then, the working angle is fixed by fastening the fasteners 23 set on the coupling part 221 and the connecting part 111, which greatly increases the adaptability to different working curved surfaces.

[0037] In some embodiments, the fixing plate 10 includes a fixing body portion 11 and protrusions 12 extending outwardly along opposite sides of the fixing body portion 11, for example, as shown in the figure. Figure 1 The left fixing plate 10 includes a fixing body 11 located on the left side and a front protrusion 12 extending to the right front side and a rear protrusion 12 extending to the right rear side along the left and right directions of the fixing body 11. Similarly, the right fixing plate 10 includes a fixing body 11 located on the right side and a front protrusion 12 extending to the left front side and a rear protrusion 12 extending to the left rear side along the right and right directions of the fixing body 11. The protrusion 12 is provided with a positioning hole for connecting to the in-situ press-in testing instrument. By setting the protrusion 12, the weight of the overall tooling can be reduced and the positioning of the testing instrument can be facilitated.

[0038] Furthermore, such as Figure 1 To increase the positioning and stability of the testing instrument, there can be multiple positioning holes, which are evenly arranged on the four protrusions 12. The positioning holes can include strip holes 121 and round holes 122. The strip holes 121 are used for initial positioning, and the round holes 122 are used to enhance the fastening. The positioning holes 121 are used to fix the in-situ testing instrument housing, and the positioning holes 122 are used to fix the four load-bearing pillars of the instrument body.

[0039] In some embodiments, such as Figure 1 The side of the fixed body 11 that is opposite to the protrusion 12 (e.g.) Figure 1 In the middle, the left side of the left fixing plate 10 and the right side of the right fixing plate 10 are provided with a connecting part 111. The connecting part 111 can be a first fixing hole, the coupling part 221 can be formed as a second fixing hole, and the fastener 23 can be formed as a fastening bolt. The fastener 23 passes through the first fixing hole and the second fixing hole to realize the fastening connection of the adjusting plate 20 and the fixing plate 10 and the working angle locking.

[0040] In some embodiments, such as Figure 1The adjusting plate 20 includes an adjusting body 21 and an upper extending arm 22 and a lower extending arm 24 extending to opposite sides of the adjusting body 21. A groove 25 is formed between the upper extending arm 22 and the lower extending arm 24. At least a portion of the fixing plate assembly is inserted into the corresponding groove 25 so that the coupling part 221 corresponds to the connecting part 111. Thus, by setting the upper extending arm 22 and the lower extending arm 24, the overall weight of the tooling can be further reduced, and the connection tightness between the fixing plate 10 and the adjusting plate 20 can be increased.

[0041] Furthermore, coupling portions 221 are respectively provided on the upper extension arm 22 and the lower extension arm 24, and the coupling portions 221 of the upper extension arm 22 and the coupling portions 221 of the lower extension arm 24 are symmetrically arranged. The fixing plate 10 is provided with connecting portions 111 at positions corresponding to the upper extension arm 22 and the lower extension arm 24, thereby forming at least two fastening points on one side of the fixing plate 10, further increasing the fastening strength.

[0042] like Figure 1 In some embodiments, the adjustment body 21 of the adjustment plate 20 is provided with a third fixing hole 31. Multiple third fixing holes 31 are provided, and they are located near the edge of the groove 25. This allows the magnetic holder to be installed on the adjustment plate 20 through the cooperation of the third fixing holes 31, effectively eliminating the need for mechanical binding and enabling quick assembly and disassembly, significantly improving operational efficiency. This allows the in-situ pressing-in testing instrument to be adjusted to an appropriate angle via the fixing plate 10 and the adjustment plate 20, and finally attached to the surface of the material to be tested 300 via the magnetic holder.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
