[0037] The following will further describe the present application in detail with reference to FIGS. Figure 1 -6.

[0038] An embodiment of the present application discloses a bearing fault diagnostic instrument.

[0039] Embodiment 1

[0040] Referring to Figure 1 、 2 、3, and 4, a bearing fault diagnostic instrument includes an instrument body 1 for fault diagnosis. Two anti-slip grips 2 are fixedly arranged on both sides of the instrument body 1 through screws. The structures and installation methods of the two anti-slip grips 2 are the same. Both sides of the two anti-slip grips 2 are fixedly connected to rubber supports 3, and the rubber supports 3 are sleeved on the four corners of the instrument body 1. The upper part of the surface of one side of the two anti-slip grips 2 away from the instrument body 1 is fixedly connected to two hanging hooks 5, and the two hanging hooks 5 are symmetrically arranged and can both be used to tie ropes.

[0041] On one side of the upper part of the instrument body 1, a dust-proof cover 4 is arranged. The outer surface of one side of the dust-proof cover 4 is fixedly connected to the inner surface of a rubber protection cover 10. A storage cavity 11 is provided on one side surface of the rubber protection cover 10. The inner surface of the storage cavity 11 is in contact with and slidably arranged with the outer surface of a rubber sliding rod 9. The opening of the storage cavity 11 is provided with an inwardly converging opening. On both sides of the inner end of the rubber sliding rod 9 located inside the storage cavity 11, outward protrusions are provided, which can limit the rubber sliding rod 9 and the storage cavity 11. The surface of the rubber sliding rod 9 away from the storage cavity 11 is fixedly connected to the surface of one side of the rubber support 3.

[0042] On both sides of the middle part of the back surface of the instrument body 1, two anti-slip patterns 8 for preventing hand slipping are fixedly arranged. A horizontal bar 7 is fixedly arranged at the lower part of the instrument body 1, and both ends of the horizontal bar 7 are fixedly connected to the opposite side surfaces of the rubber supports 3 located at the two lower corners of the instrument body 1.

[0043] The fixed arrangement of the anti-slip grips 2, the rubber supports 3, and the horizontal bar 7 can firmly fix the instrument body 1 and effectively protect and prevent the instrument body 1 from falling. The anti-slip grip 2 is the handheld part, which takes into account both anti-slip and anti-fall functions. The dust-proof cover 4 can protect the interface of the external transmission device and prevent the entry of dust, water stains, etc., which may cause damage to the device. The rubber sliding rod 9 is made of rubber material and has a certain degree of bendability. Therefore, the dust-proof cover 4 can be flipped open and closed through the cooperation of the rubber sliding rod 9 and the storage cavity 11.

[0044] Referring to Figure 2 、 5, 6. Two supporting mechanisms 6 are arranged on the upper back surface of the instrument body 1, and the structures and installation methods of the two supporting mechanisms 6 are the same. The supporting mechanism 6 includes a transverse fixing rod 61 fixedly connected to the upper back surface of the instrument body 1 by screws, and an inner groove 62 is opened on the upper part of the transverse fixing rod 61, and one side of the inner groove 62 is rotatably connected to one side of the outer supporting rod 63, and a torsion spring 612 is arranged in the middle part of the side where the outer supporting rod 63 and the inner groove 62 are connected, and one end of the torsion spring 612 is fixedly connected to the outer supporting rod 63, and the other end is fixedly connected to the bottom surface of the inner groove 62, and the middle part of the torsion spring 612 is movably penetrated by the first rotating shaft 68, and the two ends of the first rotating shaft 68 movably penetrate the two sides of the outer supporting rod 63, and are fixedly connected to the two side walls of the inner groove 62.

[0045] A through support rod groove 64 is provided in the middle of the outer support rod 63, and the support rod groove 64 is located on the side of the torsion spring 612 and is rotatably connected to the side of the inner support rod 65 away from the circular slide rod 66, and the end of the support rod groove 64 away from the semicircular arc opening 611 is fixedly penetrated by the second rotating shaft 69, and the middle part of the second rotating shaft 69 movably penetrates the junction between the inner support rod 65 and the support rod groove 64, and a circular slide rod 66 is fixedly penetrated on the side of the inner support rod 65 away from the second rotating shaft 69, and both sides of the circular slide rod 66 are slidably arranged with slide grooves 67, and the slide grooves 67 are provided in the middle of the inner walls on both sides of the inner groove 62, and the bottom surface of the slide groove 67 is flush with the bottom surface of the inner groove 62.

[0046] A plurality of array-arranged card slots 610 are provided at the bottom of the inner groove 62 , and the plurality of array-arranged card slots 610 can be set as required, and the plurality of array-arranged card slots 610 can be snap-connected with the inner support rod 65 on one side surface of the circular slide rod 66 .

[0047] The outer support rod 63 is pulled upward. Since one side of the support rod groove 64 on the outer support rod 63 is connected to one side of the inner support rod 65, the outer support rod 63 can pull the inner support rod 65 to move together, and the circular sliding rod 66 fixed at one end of the inner support rod 65 away from the second rotating shaft 69 is slidably connected with the sliding grooves 67 on both sides of the inner groove 62. Therefore, when one side of the inner support rod 65 is pulled upward, the circular sliding rod 66 will be restricted by the sliding groove 67 and slide backward in the sliding groove 67, so that the inner support rod 65 and the outer support rod 63 are supported in a triangle and are positioned at the outer support rod 63. Under the action of the torsion spring 612 arranged on one side of the first rotating shaft 68, there will be a downward pressure on one end of the outer support rod 63 when it is pulled up, so when the pulling force stops, the outer support rod 63 moves downward under the action of the torsion spring 612, and the circular slide bar 66 will also move the inner support rod 65 forward. However, since a number of slots 610 are provided at the bottom of the inner groove 62, and these slots 610 can be engaged with the inner support rod 65, the part of the inner support rod 65 located at the front end of the circular slide bar 66 will be stuck in the slot 610 under the downward pressure of the outer support rod 63 to achieve positioning.

[0048] The end of the inner support rod 65 away from the circular slide rod 66 is movably connected to the second rotating shaft 69 and the outer support rod 63, and due to the lever effect, one end of the inner support rod 65 protrudes out of the plane of the outer support rod 63. Because it is a movably connected, the end of the inner support rod 65 away from the circular slide rod 66 can be pressed. When the end of the inner support rod 65 away from the circular slide rod 66 is pressed, the clamped inner support rod 65 and the clamping groove 610 can be released, and the semicircular diameter of the semicircular arc opening 611 is consistent with the diameter of the circular slide rod 66. In this way, the semicircular arc opening 611 and the circular slide rod 66 can be better clamped and the outer support rod 63 will not be blocked by the circular slide rod 66 and tilted, so that the outer support rod 63, the inner support rod 65, and the transverse fixing rod 61 can maintain a flat surface.

[0049] The second rotating shaft 69 is located at one-third of the entire support rod groove 64 away from the semicircular arc opening 611, and is also located at one-third of the entire inner support rod 65 away from the circular sliding rod 66. When the end of the outer support rod 63 away from the torsion spring 612 is pulled up, one end of the inner support rod 65 can be pulled at the same time, so that the outer support rod 63 and the inner support rod 65 form a triangular support, which is more stable.

[0050] The implementation principle of a bearing fault diagnostic instrument in an embodiment of this application is as follows: When the staff goes out with this instrument, they can hold the anti-slip grips 2 on both sides of the instrument body 1, or they can tie a pulling rope to the hanging buckle 5 to carry this device in their hand or on their wrist. When using it on a tabletop, before placing the instrument body 1 on the tabletop, the outer support rods 63 on both sides of the back of the instrument body 1 can be pulled out, so that the outer support rods 63 drive one end of the inner support rod 65 to move upward, and the other end of the inner support rod 65 slides backward in the chute 67 through the circular slide rod 66 until the end of the inner support rod 65 located on the circular slide rod 66 is stuck with the card slot 610 opened at the bottom of the inner groove 62, so that the inner support rod 65 and the outer support rod 63 form a triangular support, which can provide a better angle for the user when the instrument body 1 is used on the tabletop, and the height can be quickly adjusted according to the clamping position of the 35 and the card slot 610.

[0051] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
