Some instruments that do not meet the waterproof standard will not be penetrated by water or will penetrate slowly when they are stationary in water. Water will penetrate into the interior only when they are in motion, which reduces the accuracy of the instrument test. Moreover, after the test is completed, the instrument will be relatively wet, and the staff needs to wipe it dry, which increases the workload of the staff. Combined with actual use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a swing component 3 and a blowing component 5 are added to the application document.

[0031] According to the above content, in order to be able to quickly and accurately test the instruments and allow the instruments to air dry quickly, the top of the transparent test box 1 is connected to the support frame 2 by bolts, and the left and right sides of the top of the support frame 2 are penetrated by electric telescopic rods 6, and the bottom end of the electric telescopic rod 6 is connected to the sealing plate 4 by bolts, and the bottom of the sealing plate 4 is installed with a swing assembly 3, and the swing assembly 3 includes a supporting mesh plate 301, and the top of the supporting mesh plate 301 is installed with a clamping assembly 8, and the top of the support frame 2 is installed with a blowing assembly 5, and the right side of the transparent test box 1 is connected to a connecting plate 9 by bolts, and the front of the connecting plate 9 is connected to an air pump 7 by bolts, and the air inlet end of the air pump 7 is fixedly connected to the right side of the transparent test box 1.

After the swing component 3 swings the instrument, the transparent test box 1 can be vacuumed by the air pump 7. While pumping air, it can be observed whether bubbles are generated in the water, so as to further test the instrument. The clamping component 8 can be used to fix the instrument when testing it, so that it will not fall when the instrument swings.

[0033] In an optional embodiment: the swing assembly 3 includes an L-shaped plate 303, the top of the L-shaped plate 303 is fixedly connected to the bottom of the sealing plate 4 by bolts, the surface of the left L-shaped plate 303 is connected to the drive motor 304 by bolts, the right end of the rotating shaft of the drive motor 304 passes through the right side of the left L-shaped plate 303, the surface of the L-shaped plate 303 is movably connected to the rotating rod 306 by a bearing, the end of the rotating rod 306 away from the L-shaped plate 303 is connected to the swing rod 302 by bolts, and the top of the supporting mesh plate 301 is fixedly connected to the bottom end of the swing rod 302 by bolts.

[0035] In an optional embodiment: the surface of the rotating shaft of the driving motor 304 and the surface of the left rotating rod 306 are both fixedly sleeved with a driving gear 305, and the two driving gears 305 are meshed with each other.

[0036] In this embodiment, the driving motor 304 drives the upper driving gear 305 to rotate, so that the lower driving gear 305 rotates, and the rotating rod 306 on the left rotates.

[0037] According to the above content, in order to be able to quickly and accurately test the instruments and allow the instruments to air dry quickly, the blowing assembly 5 includes a mounting shell 502, the bottom of the mounting shell 502 is fixedly connected to the top of the support frame 2 by bolts, the top of the inner cavity of the mounting shell 502 is connected to the blowing fan 503 by bolts, the top of the sealing plate 4 is connected to the connecting pipe 501 by bolts, the bottom of the connecting pipe 501 is fixedly connected to the blowing hood 506, the bottom end of the blowing hood 506 passes through the bottom of the sealing plate 4, the inner cavity of the mounting shell 502 is connected to the heating wire 505 by bolts, and the left and right sides of the mounting shell 502 are fixedly connected with the telescopic hose 504, and the end of the telescopic hose 504 away from the mounting shell 502 passes through the inner cavity of the support frame 2 and is fixedly connected to one end of the connecting pipe 501.

[0038] In this embodiment: after the test of the instrument is completed, the air blowing fan 503 blows air into the installation shell 502, and the blown air is heated by the electric heating wire 505. The heated air is transported into the connecting pipe 501 through the telescopic hose 504, and finally the hot air can be blown out through the air blowing hood 506, so that the hot air can be blown to the surface of the instrument, thereby drying the residual water on the instrument.

[0039] In an optional embodiment: the clamping assembly 8 includes a mounting plate 801, the bottom of the mounting plate 801 is fixedly connected to the top of the supporting mesh plate 301 by bolts, a moving rod 804 is provided through the surface of the mounting plate 801, and one end of the moving rod 804 is connected to a U-shaped plate 802 by bolts.

When placing, the moving rod 804 is pulled to squeeze the connecting spring 803 by the U-shaped plate 802 to make it shrink. After the placement is completed, the moving rod 804 is released to reset the connecting spring 803, so that the U-shaped plate 802 can tightly clamp the instruments to prevent the instruments from moving on the supporting mesh plate 301. After the fixing is completed, the electric telescopic rod 6 is extended to push the sealing plate 4 down, so that the supporting mesh plate 301 is lowered, so that the instruments can be immersed in water. At the same time, the sealing plate 4 seals the top of the transparent test box 1, and the driving motor 304 rotates the shaft to drive the driving gear 305 thereon to rotate, so that the lower driving gear 305 rotates to drive the rotating rod 306 on the left to rotate. The swing rod 302 can drive the supporting mesh plate 301 to swing, so that the instrument can move, so that water can penetrate into the unqualified products faster. After the swing test is completed, the air pump 7 is operated to evacuate the transparent test box 1. The staff can observe whether there are bubbles running out of the instrument, so as to determine which part of the instrument will penetrate water, thereby improving the accuracy of the test. After the test is completed, the electric telescopic rod 6 rises, so that the supporting mesh plate 301 moves to the top of the transparent test box 1, and the blowing fan 503 is operated to blow air to the mounting shell 502. The blown air is heated by the electric heating wire 505, and the hot air is allowed to enter the connecting pipe 501 through the telescopic hose 504. Finally, the hot air is blown to the surface of the instrument through the blowing hood 506, so that the instrument can be quickly dried without the need for the staff to wipe it, thereby reducing the workload of the staff.
