Embodiment 1
[0046] Such as Figure 1 to Figure 3 As shown, an electrostatic decay tester provided by an embodiment of the present invention includes a detection device 30 and a corona discharge device, and also includes a housing 20, a clamping device 40 and a protection device 10; wherein,
[0047] The detection device 30 is arranged in the casing 20, and the casing 20 has two operation holes for accommodating the insertion of hands. operate;
[0048] The detection device 30 includes a clamping device 40 and a sensor. The sensor is used to detect changes in charge, etc., and the clamping device 40 is used to clamp the sample to be detected to fix the sample to be detected. A clamp in the prior art can be used. Tightening device, in the present embodiment, clamping device comprises an L-shaped clamping plate 41, clamping block and bolt, and L-shaped clamping plate 41 and clamping block are all provided with through holes, and when clamping, put the sample to be tested into the L-shaped ...
Embodiment 2
[0054] On the basis of Example 1, as Figure 8 to Figure 17 As shown, the opener includes an upper sliding plate 11, a lower plate 14, several sliding blocks 12 and a block 13 corresponding to the sliding blocks 12 one by one;
[0055] Such as Figure 11 to Figure 13 As shown, the upper sliding plate 11 is circular, and its center is provided with a first central hole 111 to form a ring structure. The upper sliding plate 11 is evenly provided with a first chute 112 along the center circumference. The track of the groove 112 is arc-shaped and generally inclined to one side, and the outer circumference of the upper sliding plate 11 is provided with a wrapping 113 extending to one side;
[0056] Such as Figure 16 and Figure 17 As shown, the lower disc 14 is circular, and its center is provided with a second central hole 141, and the lower disc 14 is evenly provided with a second chute 142 along the center circumference, and the track of the second chute 142 is linear and Th...
Embodiment 3
[0062] Such as Figure 5 to Figure 7 As shown, because in the experiment, even if the high-voltage power supply is cut off, a large amount of static electricity will still remain on the sample. After the test is completed, when the sample is replaced, the residual static electricity will cause accidental injury to the operator. Therefore, this embodiment also includes electrostatic discharge. Device and electrostatic discharge switch 22, it comprises base 50, electromagnet 51, spring 52 and electrostatic discharge rod 53, base 50 is fixedly arranged on housing 20, offers guide hole on base 50, and electromagnet 51 is fixedly arranged In the guide hole, one end of the spring 52 is connected in the guide hole, and the other end is connected to the electrostatic discharge rod 53, the electrostatic discharge switch 22 is electrically connected with the electromagnet 51, the base 50 is grounded, and the electrostatic discharge rod 53 is formed by the conductive magnetic attraction. ...
