A top plate 87 is installed on the other side of the sliding frame 86. The top plate 87 consists of an inclined surface and a horizontal surface. Two bottom springs 88 are connected between the sliding frame 86 and one side in the shell 1.

[0037] The operator first connects the interface end of one of the detection devices to the lower part of two of the conductive strips 82, and then pushes one of the sliding plates 51 to move upward, and the two reset springs 52 are stretched accordingly, so that one of the placement slots 31 is completely leaked, and then the detection device is placed in the placement slot 31, and then the sliding plate 51 is released. Under the action of the two reset springs 52, the sliding plate 51 will move downward and reset, and this is repeated, so that six different detection devices can be placed in the six placement slots 31. The six placement slots 31 and the six sliding plates 51 can be used to Different detection devices are limited and fixed, and then the operator connects the clamp 64 to the output port on the charging pile, and then the operator controls the electric slider 72 to drive the main rack 73 to move along the slide rail 71. The main rack 73 will separate after being engaged with the main gear 75. During the engagement process of the main rack 73, the main gear 75 is driven to rotate sixty degrees and then stop. The main gear 75 drives the rotating drum 2, the hexagonal drum 3, the twelve sliding strips 81, the twelve conductive strips 82 and the six T-shaped frames 83 and the six detection devices placed in the six placement slots 31 through the overrunning clutch 74. The device stops after rotating sixty degrees, and the six T-shaped frames 83 rotate along the lifting ring 84. When the main rack 73 separates from the main gear 75, the main rack 73 just contacts one side of the sliding frame 86, and the main rack 73 continues to drive the sliding frame 86 and the top plate 87 to move. The two bottom springs 88 are stretched accordingly. When the inclined surface on the top plate 87 contacts the two contact rods 85, under the action of the inclined surface on the top plate 87, the two contact rods 85 drive the lifting ring 84, the six T-shaped frames 83, the twelve sliding bars 81, and the twelve conductive bars 82 to move upward, and two of them are moved upward. After the conductive strips 82 are inserted into the two slots on the two fixed strips 61 and contact the two elastic conductive sheets 62, and after the horizontal plane on the top sheet 87 moves to below the two contact rods 85, the two contact rods 85, the lifting ring 84, the six T-shaped frames 83, the twelve sliding strips 81, and the twelve conductive strips 82 no longer move upward, the electrical signal from the output port of the charging pile can be transmitted to one of the detection devices through the clip 64, the wire 63, the elastic conductive sheet 62 and the conductive strip 82 in sequence, and the data measured on the detection device is read and recorded by the device;After detecting and recording a set of data, the operator controls the electric slider 72 to drive the main rack 73 to move in the opposite direction and reset along the slide rail 71. As the main rack 73 moves in the opposite direction, under the action of the two bottom springs 88, the sliding frame 86 and the top plate 87 will move in the opposite direction and reset. The horizontal surface and the inclined surface on the top plate 87 will be separated from the two contact rods 85 in turn. Under the action of the two vertical springs 841, the lifting ring 84, the six T-shaped frames 83, the twelve sliding bars 81, and the twelve conductive bars 82 will move downward and reset. Two conductive bars 82 will be pulled out of the two slots on the two fixed bars 61 and disengaged from the two elastic conductive sheets 62. Then the main rack 73 will separate after meshing with the main gear 75. During the meshing process of the main rack 73, the main gear 75 is driven to rotate sixty degrees in the opposite direction and then stops. Under the action of the overrunning clutch 74, the main gear 75 will not drive the rotating drum 2, the hexagonal drum 3, the twelve sliding bars 81, the twelve conductive bars 82, the six T-shaped frames 83 and the six detection devices placed in the six placement slots 31 to rotate. This can be repeated to quickly switch six different devices to detect the charging pile, thereby improving the detection efficiency; after the charging pile detection is completed, the operator removes the clip 64 from the output port on the charging pile, and then clips the clip 64 on the output port of another charging pile to be detected, so that different charging piles can be continuously and quickly and accurately detected. ;

[0038] Embodiment 2: Based on embodiment 1, Figure 6-Figure 9 As shown, it also includes a correction mechanism arranged on the rotating drum 2 and the sliding frame 86, the correction mechanism is used to correct the position of the conductive strips 82, the correction mechanism enables two of the conductive strips 82 to be more accurately located directly below the two elastic conductive sheets 62, the correction mechanism includes a hexagonal block 91, a hexagonal block 91 is fixedly mounted on the rotating drum 2, a correction frame 92 is mounted on the sliding frame 86, both ends of the correction frame 92 are provided with a guide roller 93 rotatably via a bearing, and the opening width of the correction frame 92 is exactly the distance between the two opposite surfaces of the hexagonal block 91.

[0039] When the rotating drum 2 drives the hexagonal block 91 to rotate, the hexagonal block 91 will not contact the correction frame 92. When the rotating drum 2 rotates sixty degrees and stops, the sliding frame 86 drives the correction frame 92 and the two guide rollers 93 to move towards the direction close to the hexagonal block 91. Since the opening width of the correction frame 92 is exactly the distance between the two opposite surfaces on the hexagonal block 91, the hexagonal block 91 can be slightly corrected under the action of the correction frame 92. After the two guide rollers 93 contact the hexagonal block 91, the two guide rollers 93 will rotate, thereby reducing the wear of the hexagonal block 91 by the correction frame 92. The correction frame 92 can correct the hexagonal block 91, the rotating drum 2, the sliding bar 81 and the conductive bar 82, so that two of the conductive bars 82 are more accurately located directly below the two elastic conductive sheets 62, thereby improving the efficiency of charging pile detection.

[0040] Embodiment 3: Based on embodiment 2, Figure 9-13 As shown, it also includes a clamping mechanism arranged on the rotating drum 2, the fixed strip 61 and the sliding frame 86, the clamping mechanism is used to push the two elastic conductive sheets 62 to deform and swing, and the clamping mechanism enables the elastic conductive sheets 62 to contact the conductive strip 82 more closely, the clamping mechanism includes a trapezoidal block 101, a trapezoidal block 101 is installed on the horizontal surface of the top sheet 87, a guide ring 102 is fixedly installed in the rotating drum 2, a hexagonal top rod 103 is slidably arranged on the guide ring 102, and the lower end of the hexagonal top rod 103 slides through the lifting ring 84, and the two fixed strips 61 and 86 are connected to each other.

A threaded rod 106 is threadedly connected to the side of the two fixing bars 61 that are close to each other. A secondary gear 107 is installed at the end of the two threaded rods 106 that are close to each other. The two secondary gears 107 are meshed with the plurality of tooth blocks on the secondary rack 104. The ends of the two threaded rods 106 that are away from each other are respectively located on the side of the two elastic conductive sheets 62 that are close to each other.

[0041] It also includes a gasket 11. One end of the two threaded rods 106 that is away from each other is rotatably mounted with a gasket 11 through a bearing.

[0042] The gasket 11 is made of insulating material, and the two gaskets 11 are respectively in contact with the sides of the two elastic conductive sheets 62 that are close to each other.

[0043] After the sliding frame 86 drives the horizontal surface on the top plate 87 to move below the two contact rods 85, the two contact rods 85, the lifting ring 84, the six T-shaped frames 83, the twelve sliding bars 81, and the twelve conductive bars 82 no longer move upward. At this time, the sliding frame 86 drives the top plate 87 and the trapezoidal block 101 to continue moving. Since the trapezoidal block 101 is installed on the horizontal surface of the top plate 87, after the lower end of the hexagonal top rod 103 contacts the trapezoidal block 101, the hexagonal top rod 103 is driven to move upward under the action of the trapezoidal block 101, and the guide ring 102 guides the hexagonal top rod 103. The upper end of the hexagonal top rod 103 will drive the auxiliary rack 104 to move upward, and the two tooth springs 105 will stretch accordingly. Under the action of the tooth block on the auxiliary rack 104, the two auxiliary gears 107 will rotate, and the rotation of the two auxiliary gears 107 drives the two threaded rods 106 to rotate, and the two The threaded rods 106 rotate and move away from each other, and the two threaded rods 106 drive the two sub-gears 107 to rotate and move away from each other. The two sub-gears 107 will rotate and move away from each other on the tooth blocks of the sub-rack 104. The two threaded rods 106 drive the two gaskets 11 to move away from each other. The two gaskets 11 drive the two elastic conductive sheets 62 to deform and swing and press two conductive strips 82 inserted into the two slots on the two fixed strips 61, so that the elastic conductive sheets 62 are in closer contact with the conductive strips 82. The two gaskets 11 are in contact with the two elastic conductive sheets 62, so the two threaded rods 106 will not drive the two gaskets 11 to rotate, thereby reducing the wear of the two elastic conductive sheets 62, and the two gaskets 11 are made of insulating material, which can effectively avoid signal interference.
