DETAILED DESCRIPTION
[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Refer to 1 to Figure 7As shown, a micro-water measuring joint for GIS equipment includes a test head 1 and a connecting head 2, a fixing plate 3 is arranged above the test head 1 and the connecting head 2, a first clamping plate 4 and a second clamping plate 5 that can be moved are arranged on the fixing plate 3, the first clamping plate 4 and the second clamping plate 5 can be respectively abutted against the test head 1 and the connecting head 2, a moving mechanism 6 that can be used to drive the first clamping plate 4 and the second clamping plate 5 to move is arranged on the fixing plate 3, and an abutting component 7 that can abut against the test head 1 and the connecting head 2 is also arranged on the fixing plate 3.
[0025] When the device needs to be used to measure trace water or gas, the test head 1 and the connecting head 2 are first docked, and then the moving mechanism 6 is driven to work, thereby driving the first clamping plate 4 and the second clamping plate 5 to move closer to each other on the fixed plate 3, and making the first clamping plate 4 and the second clamping plate 5 respectively abut against the test head 1 and the connecting head 2, thereby fixing them, and then driving the abutment component 7 to abut against the abutting area of the test head 1 and the connecting head 2 again, thereby limiting the position of the test head 1 and the connecting head 2 again. The moving mechanism 6 can drive the first clamping plate 4 and the second clamping plate 5 to move synchronously toward or away from each other, thereby limiting and fixing the test head 1 and the connecting head 2 of different thicknesses, which is more practical, and through the abutment component 7, the test head 1 and the connecting head 2 can be limited again, so that the connection between the test head 1 and the connecting head 2 is more reliable, thereby making the test result more accurate.
[0026] Reference Figure 2 and Figure 3 As shown, the moving mechanism 6 includes a connecting block 61 and a rotating screw 64; there are two connecting blocks 61, and the two connecting blocks 61 are respectively arranged on the first clamping plate 4 and the second clamping plate 5, and the fixed plate 3 is provided with a limiting groove 62 for the connection block 61 to move; the rotating screw 64 is arranged on the fixed plate 3 through a bearing seat 63, and the rotating screw 64 is threadedly connected to the two connecting blocks 61.
[0027] By driving the rotating screw rod 64 to rotate, when the rotating screw rod 64 rotates, it will directly drive the two connecting blocks 61 to move synchronously towards or away from each other, and then directly drive the first clamping plate 4 and the second clamping plate 5 to move synchronously towards or away from each other, so that the convenience during operation can be improved, and the connecting block 61 can move in the limiting groove 62 of the fixed plate 3, so that the first clamping plate 4 and the second clamping plate 5 can be limited, preventing the first clamping plate 4 and the second clamping plate 5 from falling off the fixed plate 3.
[0028] Reference Figure 4 As shown, a rotating assembly 65 is provided on the fixed plate 3, and the rotating assembly 65 includes a mounting frame 651 and a second gear 654; the mounting frame 651 is provided on the fixed plate 3, and a rotatable rotating shaft 653 is provided on the mounting frame 651, and a first gear 652 is provided on the rotating shaft 653; the second gear 654 is provided on the rotating screw 64, and the second gear 654 is meshed and connected with the first gear 652.
[0029] By driving the rotating shaft 653 to rotate, the first gear 652 will be driven to rotate synchronously, and then the second gear 654 will directly drive the rotating screw 64 to rotate. Since the diameter of the first gear 652 is larger than the diameter of the second gear 654, when operating the rotating screw 64, it is only necessary to rotate the rotating shaft 653, thereby saving effort when operating the rotating shaft 653 and further improving the convenience of operation.
[0030] Reference Figure 6 As shown, a fixing assembly 66 is arranged on the mounting frame 651, and the fixing assembly 66 includes a fixing frame 662, abutting column 661, a limiting ring 663 and a spring 664; the fixing frame 662 is arranged on the mounting frame 651; the abutting column 661 is movably arranged on the fixing frame 662, and the side of the abutting column 661 away from the fixing frame 662 can penetrate the fixing frame 662 and be clamped with the first gear 652; the limiting ring 663 is arranged on the abutting column 661; the spring 664 is sleeved on the abutting column 661, and one end of the spring 664 is abutted against the fixing frame 662, and the other end is abutted against the limiting ring 663.
[0031] When it is necessary to drive the rotating shaft 653 to rotate, first pull the abutment column 661 to move toward the side away from the first gear 652, so that the abutment column 661 is away from the first gear 652, and the abutment column 661 will synchronously drive the limiting ring 663 to move when moving, and then the limiting ring 663 will squeeze the spring 664, so that the spring 664 is compressed and has an elastic restoring force. In this way, after the first clamping plate 4 and the second clamping plate 5 fix the test head 1 and the connecting head 2, the abutment column 661 is directly released, so that the abutment column 661 will be reset by the action of the spring 664 to abut the first gear 652 again, thereby limiting the first gear 652 to prevent the rotating screw 64 from rotating due to the action of external force, thereby making the first clamping plate 4 and the second clamping plate 5 unable to fix the test head 1 and the connecting head 2.
[0032] Reference Figure 2 As shown, the abutment assembly 7 includes a limiting plate 71 and an abutment plate 72; the limiting plate 71 has two and is symmetrically arranged on the fixed plate 3; the abutment plate 72 is movably arranged on the limiting plate 71, and the abutment plate 72 can be abutted with the connecting head 2 and the test head 1.
[0033] When the first clamping plate 4 and the second clamping plate 5 fix the test head 1 and the connecting head 2, and then move on the limiting plate 71 through the abutment plate 72, so that the abutment plate 72 abuts against the test head 1 and the connecting head 2 again, and then the test head 1 and the connecting head 2 can be limited again, so that the connection between the test head 1 and the connecting head 2 is more firmly, and it is more stable when measuring trace water or gas, so as to improve the accuracy of the test.
[0034] Reference Figure 3 and Figure 5 As shown, a moving component 73 is arranged on the limiting plate 71, and the moving component 73 includes a moving block 732, a screw rod 731 and a fixed nut 734; the moving block 732 is movably arranged on the limiting plate 71, and an arc groove 733 for the moving block 732 to move is arranged on the limiting plate 71; the screw rod 731 is arranged on the abutment plate 72, and the side of the screw rod 731 away from the abutment plate 72 can pass through the moving block 732; the fixed nut 734 is arranged on the moving block 732, and the fixed nut 734 is threadedly connected to the screw rod 731.
[0035] The movable block 732 moves in the arc groove 733 of the limiting plate 71. Therefore, when the test heads 1 and the connecting heads 2 are of different sizes, it is only necessary to move the movable block 732 in the arc groove 733 first, and then rotate the fixing nut 734. The abutment block is driven by the screw rod 731 to still abut and fix with the test head 1 and the connecting head 2, which can further improve the practicality.
[0036] Reference Figure 7 As shown, the rotating shaft 653 is provided with a rotating handle 6531 that can be used for holding.
[0037] By holding the rotating handle 6531 and then rotating the rotating handle 6531 to drive the rotating shaft 653 to rotate, it can save more effort during operation and can also further improve the convenience during operation.
[0038] Reference Figure 3 and Figure 5 As shown, the first clamping plate 4 , the second clamping plate 5 and the abutting plate 72 are all provided with flexible abutting blocks 8 .
[0039] By setting the flexible abutment block 8, when the first clamping plate 4, the second clamping plate 5 and the abutment plate 72 abut against the test head 1 and the connection head 2, damage to the test head 1 and the connection head 2 caused by large force can be prevented.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
