The protective shell 4 is in the shape of a four-prism table without a bottom, and the edge position of the protective shell 4 is provided with an outwardly extending extension fin, a through hole is formed in the extension fin, and a mounting bolt is inserted and arranged in the through hole. The mounting bolt is screwed with a first screw hole formed on the hanging plate, so as to realize the fixed connection of the protective shell 4 and the hanging plate.

[0041] With reference to Figures 2-3 , the hanging plate comprises a first plate body 21, a second plate body 22 and a third plate body 23; the second plate body 22 is transversely arranged, and the first plate body 21 and the third plate body 23 are vertically arranged; one side edge of the second plate body 22 is fixedly connected with the top edge of the first plate body 21, and the other side edge of the second plate body 22 is fixedly connected with the top edge of the third plate body 23; the first plate body 21, the second plate body 22 and the third plate body 23 are fixedly connected in one piece. A hanging groove 201 is arranged between the top end of the first plate body 21 and the top end of the second plate body 22, and the width of the hanging groove 201 is not less than the thickness of the enclosure plate 11, so that the top of the hanging plate can be hung at the top edge position of the enclosure plate 11.

[0042] With reference to Figures 2-3 , the first plate body 21 is provided with a transversely arranged locking screw hole 211, which is a through hole and communicates with the hanging groove 201; a locking bolt 5 is threadedly connected in the locking screw hole 211. When the locking bolt 5 rotates, it can move along the axial direction of the locking screw hole 211, so as to realize the compression or separation of the end of the locking bolt 5 and the enclosure plate 11.

[0043] The locking screw hole 211 is arranged above the protective shell 4, so as to avoid holes on the protective shell 4 and ensure the sealing property of the protective shell 4, thereby avoiding the contact of the vibration sensor 3 with dust and improving the service life of the utility model.

[0044] With reference to Figure 2 and Figure 4The limiting recess hole 111 is in the form of a blind hole. The limiting recess hole 111 is in the form of a circular truncated cone. The end of the locking screw hole 211 is in the form of a circular truncated cone. The end of the locking screw hole 211 can be fitted into the limiting recess hole 111, thereby limiting the hanging plate.

[0045] In use, the locking screw 5 is unscrewed, the top of the hanging plate is hung at the top edge position of the surrounding plate 11, then the hanging plate is moved transversely to align the locking screw hole 211 and the limiting recess hole 111 (the user can achieve alignment by visual observation), then the locking screw 5 is screwed into the locking screw hole 211 until the end of the locking screw 5 is pressed against the limiting recess hole 111, thereby achieving the fixed installation of the utility model.

[0046] Referring to Figure 5 The hook body 6 is arranged at the bottom of the hanging plate and can be retracted. The hook body 6 is used to buckle and pull the lower edge of the surrounding plate 11, thereby preventing the first plate body 21 from being tilted outward at the bottom, improving the stability of the hanging plate, synchronously vibrating the vibration sensor 3, the surrounding plate 11 and the wheel body 12, avoiding accidental vibration of the vibration sensor 3, thereby improving the accuracy of monitoring and protecting the vibration sensor 3 from impact damage.

In assembly, the top end of the hook body 6 is inserted into the accommodating cavity 2121, then the compression spring 2124 is arranged in the accommodating cavity 2121, and then the first pressing protrusion 2123 is fixed at the opening 2122 by a bolt, thereby achieving the installation of the hook body 6 and avoiding the disengagement of the hook body 6 from the accommodating cavity 2121. The hook body 6 can reciprocally move longitudinally in the accommodating cavity 2121. The compression spring 2124 provides an upward reset force for the hook body 6 and provides a pushing force for the hook body 6 when the hook body 6 buckles the lower edge of the surrounding plate 11.

[0049] Referring to Figure 6 The second pressing protrusion 61 is arranged above the first pressing protrusion 2123, thereby facilitating the installation of the linear compression spring 2124.
