Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] First Embodiment

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the first embodiment of the convenient and easy-to-use plastic resistance tester for battery top cover provided by this utility model; Figure 2 for Figure 1 A side view of the upper support shown; Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The diagram shows a front view of the upper support. The user-friendly plastic resistance tester for battery top covers includes: a lower support 1;

[0025] The lower support 1 is fixedly connected to the top of a support column 2. The outer surface of the support column 2 is slidably connected to an upper support 3. A cylinder 4 is installed on the upper support 3. An upper copper block 5 is fixedly connected to the bottom end of the output rod of the cylinder 4. An insulating pad 6 is installed on the top of the lower support 1. A lower copper block 7 is installed on the top of the insulating pad 6. An upper plastic 8 is provided on the top of the lower copper block 7. An electrode block 9 is provided on the upper plastic 8. A resistance tester interface 10 is provided on one side of both the upper copper block 5 and the lower copper block 7.

[0026] A lower pressure block 11 is fixedly connected to the top of the support column 2. A lower pressure screw 12 is threadedly connected to the lower pressure block 11. The bottom end of the lower pressure screw 12 is rotatably connected to the top of the upper bracket 3. An adjustment knob 13 is fixedly connected to the top end of the lower pressure screw 12.

[0027] By manually rotating the adjustment knob 13, the downward screw 12 can be rotated, thereby adjusting the position of the upper bracket 3 and the position of the cylinder 4. However, it is difficult to keep the cylinder 4 from moving after being pressed down by the clamping force of the upper bracket 3 alone, so the downward screw 12 is also needed to help fix the cylinder 4 in the height direction.

[0028] The top end of the output rod of the cylinder 4 is fixedly connected to a limiting block 14. The limiting block 14 can limit the output rod of the cylinder 4 to ensure that it is within the specified stroke.

[0029] A control switch 15 is installed on one side of the upper bracket 3. The control switch 15 is located on one side of the cylinder 4 and is electrically connected to the cylinder to control the opening and closing of the cylinder 4.

[0030] The working principle of the convenient and easy-to-use plastic resistance tester for battery top covers provided by this utility model is as follows:

[0031] During testing, first connect the tester probes to the resistance tester interface 10 on the upper copper block 5 and the lower copper block 7. Then, place an electrode 9 inside the upper plastic block 8 and put it on the lower copper block 7. Press the control switch 15 to press down the cylinder 4. At this time, the upper copper block 5 presses down on the electrode 9 and applies a continuous downward pressure to it, simulating the downward pressure on the upper plastic block 8 after riveting. At this time, the resistance tester can measure the resistance data of the upper plastic block 8.

[0032] Compared with related technologies, the convenient and easy-to-use plastic resistance tester for battery top covers provided by this utility model has the following advantages:

[0033] During testing, the tester probes are first connected to the resistance tester interface 10 on the upper copper block 5 and the lower copper block 7. An electrode 9 is placed inside the upper plastic block 8 and then placed on the lower copper block 7. The switch 15 is pressed to cause the cylinder 4 to press down. At this time, the upper copper block 5 presses down on the electrode 9 and applies a continuous downward pressure to it, simulating the downward pressure on the upper plastic block 8 after riveting. The resistance tester can then measure the resistance data of the upper plastic block 8, which can test the resistance of the upper plastic block 8, avoiding the situation of resistance exceeding the standard. It also achieves the effect of accurate detection position, which is conducive to process improvement. The operation is simple and quick, reducing manpower and material resources.

[0034] Second Embodiment

[0035] Please refer to the following: Figure 4-5 Based on the special tool for aligning the coupling of the desulfurization slurry circulation pump provided in the first embodiment of this application, the second embodiment of this application proposes another special tool for aligning the coupling of the desulfurization slurry circulation pump. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0036] Specifically, the difference in the special tool for aligning the desulfurization slurry circulation pump coupling provided in the second embodiment of this application is that a fixing component 16 is installed on the right side of both the upper copper block 5 and the lower copper block 7. The fixing component 16 includes a mounting sleeve 161, a groove 162 is provided on the mounting sleeve 161, a sliding block 163 is slidably connected in the groove 162, a compression spring 164 is provided between the sliding block 163 and the groove 162, a moving rod 165 is fixedly connected to the sliding block 163, and a fixing block 166 is fixedly connected to one end of the moving rod 165.

[0037] The fixing component 16 is installed at the resistance tester interface 10, and the mounting sleeve 161 is on the same axis as the resistance tester interface 10.

[0038] The outer surface of the mounting sleeve 161 is threadedly connected to a threaded sleeve 167, and a tapered sleeve 168 is rotatably connected to the right side of the threaded sleeve 167. The tapered sleeve 168 is slidably connected to the mounting sleeve 161.

[0039] Compared with related technologies, the convenient and easy-to-use plastic resistance tester for battery top covers provided by this utility model has the following advantages:

[0040] When the tester probes are connected to the resistance tester interface 10 on the upper copper block 5 and the lower copper block 7, the tester probes are first inserted into the mounting sleeve 161, and then inserted into the resistance tester interface 10. Then, by manually rotating the threaded sleeve 167, the threaded sleeve 167 moves to the right, which drives the conical sleeve 168 to move to the right. This causes the inner conical surface of the conical sleeve 168 to press against the moving rod 165, causing the moving rod 165 to move towards the inside of the mounting sleeve 161. The tester probes are then clamped and fixed by the fixing block 166, which improves the stability of the probe connection and prevents them from falling off.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
