[0003] For example, the LWIN-BC302 multifunctional vibration and bearing condition detector on the market needs to connect the cable to the interface and sensor of the detector before use;

[0004] However, when not in use, the three need to be disassembled and stored. During this process, a single piece may be lost, or the open interface may be accidentally worn or blocked, which is inconvenient to take out. Utility Model Content

[0005] In view of the above defects, the utility model provides a flow vibration meter, including an instrument body, a cable and an interface installed at the instrument body, wherein the outer ring at the top of the interface is provided with a thread layer I, the threaded sleeve of the thread layer I is provided with a protective sleeve, and the top of the protective sleeve is fixed with a bolt;

[0006] A threaded groove for bolt threaded connection is provided at the bottom end of the instrument body, and a card slot is provided on the front and rear sides of the bottom end of the instrument body. A sliding bottom plate is carded in the card slot, and an open groove matching the protective cover is provided on the sliding bottom plate. A sliding block is fixed in the middle of the upper surface of the sliding bottom plate, and a sliding groove movably connected to the sliding block is provided at the bottom end of the instrument body.

[0007] Furthermore, a gap value between the thread layer II opened at the bolt and the protective sleeve is equal to a thickness value of the open groove.

[0008] Furthermore, a retention groove is provided on the right side of the instrument body, and the right side of the sliding bottom plate is an arc surface and is adapted to the size of the retention groove.

[0009] Furthermore, the retention groove and the arc surface on the right side of the sliding bottom plate are adsorbed and fixed by magnets embedded in them.

[0010] Furthermore, the sliding block and the sliding groove are both T-shaped.

[0011] Furthermore, the sliding bottom plate is engaged with the two card slots via a set of fixed card strips.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When not in use, it can be movably connected to the interface through the protective cover to keep the interface sealed and achieve the protective effect. When picking up and moving, the cable can be connected to the instrument body bracket through the interface and the protective cover to form the form of a handbag, which is more convenient when picking up and moving.

[0019] To facilitate the understanding of the present utility model, the device of the present utility model will be described more comprehensively below with reference to the relevant drawings. Embodiments of the device are shown in the drawings. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "arranged" should be understood in a broad sense. For example, it can be fixedly connected and arranged, or detachably connected and arranged, or integrally connected and arranged. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] Embodiment

[0022] As Figures 1-4 shown, this embodiment provides a mobile vibration measuring instrument, including an instrument body 1, a cable 2, and an interface 4 installed at the instrument body 1. A thread layer I 8 is provided on the outer circle at the top of the interface 4, and a protective cover 3 is threadedly sleeved on the thread layer I 8. A bolt 7 is fixed at the top of the protective cover 3, and the clearance value between the thread layer II provided at the bolt 7 and the protective cover 3 is equal to the thickness value of the opening groove 13.
