[0044] like Figure 5 As shown, a dustproof component 8 located outside the heat dissipation hole 3 is provided on the outside of the temperature calibrator body 1, and the dustproof component 8 includes a dustproof plate 801 and a limiting sliding plate 802;

[0045] The dustproof plate 801 is movably installed on the outside of the heat dissipation hole 3, and the limiting sliding plate 802 is fixedly installed on the bottom of the dustproof plate 801, and the inner end is slidably connected to the outside of the temperature calibrator body 1.

[0046] By adopting the above solution, the overall up and down movement of the dustproof plate 801 can be limited by the design of the limiting sliding plate 802.

[0047] like Figure 1 and 8 As shown, a linkage assembly 9 located below the limit sliding plate 802 is disposed on the outer side of the temperature calibrator body 1, and the linkage assembly 9 includes a first piston cylinder 901, a triangular plate 902, a second piston cylinder 903, a second connecting pipe 904 and a first spring 905;

[0048] The first piston cylinder 901 is fixedly installed on the outside of the temperature calibrator body 1 and below the front end of the limiting sliding plate 802, the second piston cylinder 903 is fixedly installed on the outside of the temperature calibrator body 1 and below the rear end of the first piston cylinder 901, the rear end of the first piston cylinder 901 and the top of the rear end of the second piston cylinder 903 are fixedly installed with a triangular plate 902, the second connecting pipe 904 is fixedly connected between the middle of the front ends of the first piston cylinder 901 and the second piston cylinder 903, the first spring 905 is fixedly installed at the front end of the inner cavity of the first piston cylinder 901, and the rear end of the top of the first piston cylinder 901 is fixedly connected to the other end of the first connecting pipe 603.

[0049] By adopting the above scheme: through the elastic force of the first spring 905, the output end of the first piston cylinder 901 and the front end triangular plate 902 can be pushed backward as a whole, so that the gas in the inner cavity of the first piston cylinder 901 is introduced into the inner cavity of the second piston cylinder 903 through the second connecting pipe 904, so that the output end of the second piston cylinder 903 drives the rear end triangular plate 902 forward, and finally the two triangular plates 902 move away from each other.

[0050] like Figures 1 to 3 As shown, a handle 10 located above the rear end of the display screen 2 is fixedly mounted on the top of the temperature calibrator body 1 , and a rubber sleeve 11 is provided on the bottom surface of the top of the handle 10 .

[0051] With the above solution, by providing the handle 10 , the user can grab the handle 10 to lift the entire temperature calibrator body 1 for mobile transportation.

[0052] like Figure 6 As shown, a clamping assembly 12 is disposed on the inner side of the bottom of the handle 10, and the clamping assembly 12 includes a clamping plate 1201 and a sliding block 1202;

[0053] The clamping plate 1201 is movably mounted on the bottom of the inner side of the handle 10 , and the sliding blocks 1202 are fixedly mounted on both sides of the clamping plate 1201 and the inner wall of the handle 10 .

[0054] By adopting the above solution, by providing the sliding block 1202, when the clamping plate 1201 moves up and down, the sliding block 1202 can slide vertically along the inside of the handle 10 to limit it.

[0055] like Figure 7 As shown, a lifting assembly 13 is disposed inside the temperature calibrator body 1 and is located outside and below the clamping plate 1201. The lifting assembly 13 includes a first air groove 1301, a moving rod 1302, a second spring 1303 and a connecting arm 1304.

[0056] The first air groove 1301 is opened inside the temperature calibrator body 1 and on both sides of the bottom of the clamping plate 1201, the moving rod 1302 is movably installed in the inner cavity of the first air groove 1301, the second spring 1303 is fixedly installed between the inner side of the outer end of the moving rod 1302 and the inner wall of the first air groove 1301, and the connecting arm 1304 is hinged between the inner end of the moving rod 1302 and the two sides of the middle of the bottom end of the clamping plate 1201.

[0057] The above solution is adopted: by providing a second spring 1303, due to the elastic force of the second spring 1303, the two moving rods 1302 can be pushed to move in opposite directions, so that the connecting arm 1304 pulls the clamping plate 1201 to move downward as a whole.

[0058] like Figure 6As shown, a trigger assembly 14 located above the rubber sleeve 11 is disposed at the top of the handle 10, and the trigger assembly 14 includes a second air groove 1401, a trigger rod 1402 and a connecting groove 1403;

[0059] The second air groove 1401 is opened in the middle of the top of the handle 10, the trigger rod 1402 is movably installed inside the second air groove 1401, and the bottom end extends to the middle of the handle 10, and the connecting groove 1403 is opened inside the handle 10 and between the top of the outer side of the second air groove 1401 and the middle of the outer side of the first air groove 1301.

[0060] By adopting the above solution, the trigger rod 1402 is provided. When the trigger rod 1402 is pressed upward, the gas at the top of the inner cavity of the second gas groove 1401 will be introduced into the inner cavity of the first gas groove 1301 through the connecting groove 1403, so that the moving rod 1302 is driven to move toward each other.

[0061] like Figure 6 As shown, a partition plate 15 is fixedly mounted at the middle of the top end of the trigger rod 1402 .

[0062] By adopting the above scheme: through the design of the partition plate 15, the inner cavity at the top of the second gas groove 1401 can be smoothly divided into two parts, so that when the trigger rod 1402 is upward, the gas in the cavities on both sides of the top of the second gas groove 1401 is respectively introduced into the first gas groove 1301 through the connecting groove 1403, so that the two moving rods 1302 are driven towards each other.

[0063] The working principle and use process of the present invention:

[0064] First, when the user needs to lift the temperature calibrator body 1 to the designated working position, the user can first grab the handle 10 by hand, and then when lifting the handle 10, the rubber cover 11 will be squeezed flat, and the trigger rod 1402 will be pushed upward in the inner cavity of the second air groove 1401, so that the gas in the inner cavity of the second air groove 1401 can be pushed to the inner cavity of the first air groove 1301 through the connecting groove 1403. The air pressure in the inner cavity of the first air groove 1301 increases, which can smoothly push the two moving rods 1302 to move toward each other, so that the connecting arm 1304 pushes the clamping plate 1201 upward as a whole, so that the bottom of the clamping plate 1201 fits the bottom of the hand for squeezing, and the hand is smoothly clamped between the clamping plate 1201 and the rubber cover 11, and the handle 10 is firmly grasped.

[0065] Afterwards, when the temperature calibrator body 1 is moved to the specified position for use, the fixing bolt 7 can be rotated forward first to make the rear end disengage from the outer side of the protective plate 401, thereby releasing the fixing effect on the protective plate 401 as a whole. Then the user can push the dustproof plate 801 and the limiting sliding plate 802 downward as a whole, so that the outer end parts on both sides of the bottom of the limiting sliding plate 802 extend to the inner wall of the triangular plate 902 and slide downward obliquely, so as to smoothly drive the triangular plate 902 to move away from each other. The negative pressure generated in the inner cavity of the second piston cylinder 903 will draw away the gas in the inner cavity of the first piston cylinder 901 through the second piston cylinder 903, so that the two triangular plates 902 can move away from each other smoothly, and finally the dustproof plate 801 can move downward smoothly, releasing the dust blocking of the heat dissipation hole 3, so that heat dissipation can be performed during the subsequent operation of the temperature calibrator body 1.

[0066] While the triangular plate 902 moves in opposite directions, the output end of the first piston cylinder 901 is retracted into the first piston cylinder 901, so that the inner cavity of the inner end of the first piston cylinder 901 generates negative pressure, and the gas in the inner cavity of the pneumatic cylinder 601 can be extracted through the first connecting pipe 603, so that the pneumatic rod 602 is driven downward, which can drive the drive shaft 502 and the disc 501 to rotate, and at the same time, the rotating fixing bolt 7 is rotated forward as a whole, so that the rear end is separated from the outer inside of the protective plate 401, and the fixing effect on the protective plate 401 as a whole is released, and then the disc 501 can drive the first connecting member 403 to rotate, so that the linkage plate 404 links the second connecting member 405 and the protective plate 401 to smoothly rotate 90 degrees, and finally the two protective plates 401 are flipped open, and the shielding protection of the display screen 2 can be released, and the rotating fixing bolt 7 is rotated backward so that the rear end is inserted into the inner side of the outer end of the protective plate 401, and the protective plate 401 is fixed as a whole, and then the operator can smoothly control the temperature calibration process of the temperature calibrator body 1 as a whole through the display screen 2.
