[0073] Furthermore, the centralizer 43 can be arranged in the middle of the sleeve 41 and the anti-pressure cylinder 42 in the vertical direction, and the sleeve assembly 4 is arranged as a cylindrical structure extending in the vertical direction. The centralizer 43 is arranged in the middle of the sleeve 41 and the anti-pressure cylinder 42 in the vertical direction, and the centralizer 43 is pressed between the anti-pressure cylinder 42 and the sleeve 41 along the radial direction of the sleeve 41, which can ensure that the distance between the anti-pressure cylinder 42 and the sleeve 41 at all points along the circumferential direction is equal, thereby ensuring that the vibration force exerted on each point of the probe is the same, thereby ensuring measurement accuracy.

[0076] When the vibration testing device 100 simulates vibration, the vibration table can transmit the vibration to the mounting base plate 1, so that the support plate 6 and the first step sleeve 2 can transmit the vibration to the sleeve assembly 4, ensuring the consistency of the vibration force at various parts of the sleeve assembly 4, thereby ensuring the accuracy of the test.

[0079] In other embodiments, there are multiple support plates 6 , and the multiple support plates 6 are distributed sequentially in the circumferential direction of the sleeve assembly 4 .

[0080] Specifically, the support plate 6 can also be set to multiple, that is, the support plate 6 can be set to two, three or four, etc., to ensure the support reliability of the sleeve assembly 4. The multiple support plates 6 can be distributed in sequence in the circumferential direction of the sleeve assembly 4, and the multiple support plates 6 are equally spaced in the circumferential direction of the sleeve assembly 4, so that the supporting forces provided by the multiple support plates 6 to the sleeve assembly 4 are equal, and the vibration forces transmitted by the multiple support plates 6 to the sleeve assembly 4 are also equal, thereby ensuring that the vibration forces received by various parts of the probe in the sleeve assembly 4 are equal, so as to ensure the accuracy of the test.

[0081] In some embodiments, the support plate 6 includes a main board portion 61 and a connecting plate portion 62, the upper end of the main board portion 61 is connected to the outer peripheral wall of the middle part of the sleeve assembly 4 through a first fastener 611, the connecting plate portion 62 is connected to the lower end of the main board portion 61, and the connecting plate portion 62 is connected to the mounting base plate 1 through a second fastener 621.

The first fastener 611 can be set to a screw, etc., with a simple structure and low setting cost. The upper end of the main board portion 61 is connected to the outer peripheral wall of the middle part of the sleeve assembly 4 by the first fastener 611, so that the upper end of the main board portion 61 and the outer peripheral wall of the middle part of the sleeve assembly 4 are detachable, which is convenient for installation and later maintenance.

[0083] Furthermore, the lower end of the main board portion 61 is connected to the connecting plate portion 62, and the connecting plate portion 62 is connected to the mounting base plate 1 through a second fastener 621.

[0084] And the width of the connecting plate portion 62 in the horizontal direction is greater than the width of the main board portion 61 in the horizontal direction, that is, the width of the connecting plate portion 62 in the horizontal direction is set to be larger, and the width of the main board portion 61 in the horizontal direction is smaller. The connecting plate portion 62 is connected to the mounting base plate 1, and the width of the connecting plate portion 62 in the horizontal direction is set to be larger, so that the contact area between the connecting plate portion 62 and the mounting base plate 1 is larger, ensuring the support reliability, and the main board portion 61 is connected to the sleeve assembly 4, and the width of the main board portion 61 in the horizontal direction is set to be smaller, so that the main board portion 61 can match the size of the sleeve assembly 4, ensuring the connection reliability between the main board portion 61 and the sleeve assembly 4.
