[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0036] The utility model provides a machine status monitoring and diagnostic instrument, see Figure 1 The diagnostic apparatus comprises a diagnostic apparatus body 1 and a protective inner cover 2 sleeved on the outer side of the diagnostic apparatus body 1, wherein the protective inner cover 2 is connected to a protective outer cover 4 via a telescopic assembly 3. The protective inner cover 2 and the protective outer cover 4 are used to protect the diagnostic apparatus body 1.

[0037] In one embodiment, the front of the protective shell 4 is connected to the box door 5 through two sets of leaves, and the outer sides of the protective shell 4 and the box door 5 are provided with a limiting component 6. The left and right sides of the protective shell 4 and behind the limiting component 6 are fixedly connected with a heat dissipation box 7.

[0038] Exemplarily, the limit of the box door 5 by the limit assembly 6 is canceled. After the box door 5 is opened, the protective inner cover 2 is slid out of the protective outer shell 4 through the telescopic assembly 3. The protective inner cover 2 is connected to the protective outer shell 4 through the telescopic assembly 3. The diagnostic instrument body 1 is installed inside the protective inner cover 2, and then the mechanical state is monitored by the diagnostic instrument body 1. After the monitoring is completed, the protective inner cover 2 is retracted into the protective outer shell 4 through the telescopic assembly 3. When the box door 5 is closed, the box door 5 is limited by the limit assembly 6. At this time, the residual heat of the diagnostic instrument body 1 is discharged from the protective outer shell 4 through the heat dissipation box 7.

[0039] In one embodiment, see Figure 3 , Figure 4 as well as Figure 5 The telescopic component 3 is used for a stable connection between the protective inner cover 2 and the protective outer cover 4 , and the telescopic component 3 can also enable the protective inner cover 2 to be telescoped in the protective outer cover 4 .

[0040] The protective inner cover 2 is connected to the protective outer cover 4 through a telescopic assembly 3. The telescopic assembly 3 includes three groups of first telescopic columns 301, rotating shafts 302, second telescopic columns 303 and sliding blocks 304. The first telescopic column 301 is arranged between the protective inner cover 2 and the protective outer cover 4. The first telescopic column 301 is rotatably connected to the second telescopic column 303 through the rotating shaft 302. The first telescopic column 301 and the second telescopic column 303 are respectively slidably connected to the protective inner cover 2 and the protective outer cover 4 through a number of sliding blocks 304. The first telescopic column 301 and the second telescopic column 303 are designed in a cross structure.

[0041] After placing the diagnostic instrument body 1 inside the protective inner cover 2, slide the protective inner cover 2 into the protective outer shell 4 through the telescopic assembly 3, and push the protective inner cover 2 toward the position of the protective outer shell 4. The first telescopic column 301 and the second telescopic column 303 are designed in a cross structure, and the upper and lower sides of the first telescopic column 301 and the second telescopic column 303 are driven to move by a plurality of sliding blocks 304. The first telescopic column 301 and the second telescopic column 303 are rotated through the rotating shaft 302 to slide the protective inner cover 2 into the protective outer shell 4. At the same time, the first telescopic column 301 and the second telescopic column 303 can prevent the protective inner cover 2 from falling from the protective outer shell 4, and firmly fix the protective inner cover 2 in the protective outer shell 4.

[0042] In one embodiment, see Figure 1-Figure 4 A limiting assembly 6 is provided on the outer sides of the protective shell 4 and the box door 5 .

[0043] The limiting assembly 6 includes two groups of connecting frames 601, a rotating frame 602, a connecting spring 603, a connecting frame 604 and a limiting column 605. The two groups of connecting frames 601 are respectively fixedly connected to the outer sides of the protective shell 4 and the box door 5. The upper and lower sides of the connecting frame 601 are rotatably connected to the rotating frame 602. The two groups of rotating frames 602 are connected to the connecting frame 604 through the connecting spring 603. The limiting column 605 is fixedly connected between the two groups of connecting frames 604.

[0044] The box door 5 is limited by the limiting assembly 6. When the box door 5 is closed, the limiting column 605 is pulled toward the position of the box door 5. The limiting column 605 is rotated on the connecting frame 601 on the outside of the protective shell 4 through the rotating frame 602. The limiting column 605 is rotated to the connecting frame 601 on the outside of the box door 5. At this time, the connecting spring 603 is pulled by the connecting frame 604 to extend the connecting spring 603, and then the limiting column 605 is clamped to the connecting frame 601 on the outside of the box door 5. The box door 5 is limited by the clamping of the limiting column 605 and the connecting frame 601.

[0045] In one embodiment, see Figure 1-Figure 3 A heat dissipation box 7 is fixedly connected to the left and right sides of the protective shell 4 and behind the limiting component 6.

[0046] A layer of filter 701 is fixedly connected to the surface of the heat sink 7, two sets of cooling fans 702 are installed inside the heat sink 7 and on the inner side of the filter 701, and a number of cooling fins 703 are fixedly connected inside the heat sink 7 and on the upper and lower sides of the cooling fans 702. The several cooling fins 703 all penetrate the protective shell 4 and extend to the inside of the protective shell 4.

[0047] After using the diagnostic instrument, the diagnostic instrument body 1 is put into the protective shell 4. At this time, the residual heat of the diagnostic instrument body 1 can be conducted to the heat sink 7 through the heat dissipation fins 703, and the heat is discharged from the heat sink 7 by the blowing of the heat dissipation fan 702. At the same time, during daily use, the outside air can be filtered through the filter net 701 to prevent dust in the air from entering the heat sink 7.

[0048] The working process of the utility model is as follows: when using the diagnostic instrument, first cancel the limit of the box door 5 by the limit assembly 6. After opening the box door 5, slide the protective inner cover 2 out of the protective outer shell 4 through the telescopic assembly 3. The protective inner cover 2 is connected to the protective outer shell 4 through the telescopic assembly 3. The diagnostic instrument body 1 is installed inside the protective inner cover 2. Then, the mechanical state is monitored through the diagnostic instrument body 1. After the monitoring is completed, the protective inner cover 2 is retracted into the protective outer shell 4 through the telescopic assembly 3. When the box door 5 is closed, the box door 5 is limited by the limit assembly 6. At this time, the residual heat of the diagnostic instrument body 1 is discharged from the protective outer shell 4 through the heat dissipation box 7. Compared with the existing diagnostic instrument, the utility model improves the overall practicality of the diagnostic instrument through design.
