Description

Technical Field

[0001] This utility model relates to the field of conductive foam testing technology, and in particular to a conductive foam conductivity testing device. Background Technology

[0002] Conductive foam refers to a product in which conductive cloth is wrapped around flame-retardant sponge and subjected to a series of treatments to give it good surface conductivity. It can be easily fixed to the device that needs to be shielded with adhesive tape. During the production process of conductive foam, it is usually necessary to test its conductivity.

[0003] The prior art patent CN220568706U discloses a conductive foam conductivity testing device. This device uses the rebound force of a spring and the torsional force of a torsion spring to drive a rotating plate downwards and an arc-shaped retaining strip to rotate, thus fixing the conductive foam to both sides for testing. This setup facilitates the fixing and testing of the conductive foam. However, during use, the operator needs to adjust the positions of the conductive and test contacts separately, and simultaneously pull the rotating plate upwards and rotate the arc-shaped retaining strip upwards to remove and place the conductive foam. This operation is cumbersome and inconvenient, and its practicality needs further improvement. Therefore, this utility model discloses a conductive foam conductivity testing device to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a conductive foam conductivity testing device to solve the problem mentioned in the background art, which requires not only adjusting the positions of the conductive contacts and the test contacts separately, but also requires the tester to simultaneously pull the rotating plate upward and rotate the arc-shaped clip upward to pick up and put down the conductive foam, making the operation cumbersome and inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conductive foam conductivity testing device, comprising a test platform, a power tester, and two conductive blocks. A U-shaped frame is fixedly installed on the top of the test platform, and the power tester is fixedly mounted on the top of the U-shaped frame. A bidirectional lead screw is rotatably installed on the inner side wall of the U-shaped frame. Two moving blocks are threaded onto the bidirectional lead screw, and inclined rotating rods are rotatably connected to the bottom of each of the two moving blocks. A strip box is rotatably connected to the bottom ends of the two inclined rotating rods. One end of the bidirectional lead screw extends outside the U-shaped frame and is fixedly installed with an operating device. The control knob has rectangular sliding holes on both sides of the strip box that are far apart from each other. Horizontal sliding rods are slidably installed in both rectangular sliding holes. An adjustment unit is installed on the strip box to allow the two horizontal sliding rods to move simultaneously towards each other or simultaneously away from each other. Connecting sleeves are fixedly installed at the far ends of the two horizontal sliding rods. Vertical sliding rods are slidably installed in both connecting sleeves. Insulating seats are fixedly installed at the bottom ends of the two vertical sliding rods. Two conductive blocks are respectively fixed on the bottom of the two insulating seats. Elastic clamping elements that press down on the insulating seats are installed on the connecting sleeves.

[0006] Preferably, the elastic clamping element includes a clamping spring, with its two ends fixedly mounted on the top of the insulating base and the bottom of the connecting sleeve, respectively.

[0007] Preferably, the adjustment unit includes a control shaft rotatably mounted on the inner wall of the bottom of the strip box, a central gear fixedly sleeved on the control shaft, L-shaped racks fixedly mounted at the close ends of the two horizontal slide rods, both L-shaped racks meshing with the central gear, the top end of the control shaft extending outside the strip box and having a hexagonal sliding hole, a hexagonal slide rod slidably mounted in the hexagonal sliding hole, and an adjustment knob fixedly mounted at the top end of the hexagonal slide rod.

[0008] Preferably, multiple insert rods are evenly fixedly installed at the bottom of the adjustment knob, and multiple insertion holes are evenly opened at the top of the strip box, with the bottom end of the insert rod extending into the insertion hole.

[0009] Preferably, a horizontal guide rod is fixedly installed on the inner side wall of the U-shaped frame, and both moving blocks are slidably sleeved on the horizontal guide rod.

[0010] Preferably, an insulating pad is fixed on the top of the test bench.

[0011] Preferably, the bottom of the test platform is uniformly provided with multiple support legs, and each of the multiple support legs is provided with a caster wheel at its bottom end.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model has a reasonable structure. When the adjustment knob is rotated, the hexagonal slide bar, control shaft, central gear and L-shaped rack will drive the two horizontal slide bars to move towards each other or away from each other at the same time. Then, the connecting sleeve, vertical slide bar and insulating seat will drive the two conductive blocks to move towards each other or away from each other together. This allows for quick adjustment of the distance between the two conductive blocks to adapt to conductivity testing of conductive foam of different lengths. When the control knob is rotated, the bidirectional lead screw, moving block and tilting rod will drive the strip box to move up and down, which will drive the two conductive blocks to move up and down together. This allows the tester to quickly pick up and put away the conductive foam for conductivity testing. It is simple to operate, convenient to use and has good practicality.

[0014] 2. In this utility model, through the coordinated arrangement of the connecting sleeve, vertical slide rod, insulating seat, and compression spring, when the control strip box moves downward to make the conductive block contact the conductive foam, and the strip box continues to move downward, the compression spring will be compressed by the horizontal slide rod and connecting sleeve to undergo elastic deformation. At this time, under the elastic force of the compression spring, the insulating seat can be pressed downward so that the conductive block will always be in close contact with the conductive foam. Thus, during the test, the poor contact between the conductive block and the conductive foam can be effectively avoided, ensuring the normal progress of the test.

[0015] 3. In this utility model, when the adjustment knob is pulled upwards until the plug rod moves out of the socket, the adjustment knob can be directly rotated for adjustment. When the adjustment knob is released, under the action of gravity, the adjustment knob will automatically move downwards, thereby driving the plug rod to automatically insert into the socket and fix the adjustment knob so that it cannot be rotated. Thus, during use, it can effectively prevent the distance between the two conductive blocks from changing automatically, making it stable and reliable during use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figures 1-4The conductive foam conductivity testing device shown includes a test platform 1, a power tester 2, and two conductive blocks 3. Both conductive blocks 3 are electrically connected to the power tester 2 via wires. A U-shaped frame 4 is fixedly mounted on the top of the test platform 1, and the power tester 2 is fixedly mounted on the top of the U-shaped frame 4. A bidirectional lead screw 5 is rotatably mounted on the inner side wall of the U-shaped frame 4. Two moving blocks 6 are threaded onto the bidirectional lead screw 5. An inclined rotating rod 7 is rotatably connected to the bottom of each of the two moving blocks 6. A strip box 8 is rotatably connected to the bottom of both inclined rotating rods 7. The two inclined rotating rods 7 are symmetrically arranged in an inverted "V" shape. One end of the bidirectional lead screw 5 extends outside the U-shaped frame 4 and is fixedly mounted with a control knob 9. Rectangular sliding holes are opened on the two far apart sides of the strip box 8. Horizontal sliding rods 10 are slidably mounted in each of the two rectangular sliding holes. An adjustment unit is installed on the strip box 8 to allow the two horizontal sliding rods 10 to move simultaneously towards or away from each other. The section unit includes a control shaft 15 rotatably mounted on the inner wall of the bottom of the strip box 8. A central gear 16 is fixedly sleeved on the control shaft 15. L-shaped racks 17 are fixedly mounted on the ends of two horizontal slide rods 10 that are close to each other. Both L-shaped racks 17 mesh with the central gear 16. The two L-shaped racks 17 are centrally symmetrical about the central gear 16. The top of the control shaft 15 extends to the outside of the strip box 8 and has a hexagonal sliding hole. A hexagonal slide rod 18 is slidably mounted in the hexagonal sliding hole. An adjustment knob 19 is fixedly mounted on the top of the hexagonal slide rod 18. A connecting sleeve 11 is fixedly mounted on the ends of the two horizontal slide rods 10 that are far from each other. A vertical slide rod 12 is slidably mounted in both connecting sleeves 11. An insulating seat 13 is fixedly mounted on the bottom of both vertical slide rods 12. Two conductive blocks 3 are fixedly mounted on the bottom of the two insulating seats 13 respectively. An elastic pressing element that presses down on the insulating seat 13 is mounted on the connecting sleeve 11.

[0024] With the above structure, when the adjustment knob 19 is rotated, the control shaft 15 will rotate via the hexagonal slide bar 18. The rotation of the control shaft 15 will, through the central gear 16 and two L-shaped racks 17, cause the two horizontal slide bars 10 to move simultaneously towards or away from each other. This, in turn, will cause the two conductive blocks 3 to move simultaneously towards or away from each other via the connecting sleeve 11, the vertical slide bar 12, and the insulating seat 13. This allows for rapid adjustment of the distance between the two conductive blocks 3, suitable for conducting conductivity tests on conductive foams of different lengths. After adjustment, the control knob 9 can be rotated. Rotating the control knob 9 will... The two-way lead screw 5 and two moving blocks 6 drive the two tilting rods 7 to tilt and rotate up and down simultaneously. The simultaneous tilting and rotation of the two tilting rods 7 will drive the strip box 8 to move up and down. In turn, the horizontal slide rod 10, connecting sleeve 11, vertical slide rod 12 and insulating seat 13 will drive the two conductive blocks 3 to move up and down together. When the two conductive blocks 3 move down to fit with the conductive foam, the power tester 2 can be turned on to conduct a conductivity test. After the test is completed, the two conductive blocks 3 can be moved up to detach from the conductive foam. At this time, the tester can directly remove the conductive foam. The operation is simple, convenient and practical.

[0025] like Figure 3 As shown, the elastic clamping element includes a clamping spring 14, with its two ends fixedly mounted on the top of the insulating base 13 and the bottom of the connecting sleeve 11, respectively. The advantage of this arrangement is that when the strip box 8 moves downwards, causing the conductive block 3 to come into contact with the conductive foam, further downward movement of the strip box 8 will compress the clamping spring 14 via the horizontal slide rod 10 and the connecting sleeve 11, causing elastic deformation. At this time, under the elastic force of the clamping spring 14, the insulating base 13 can be pressed downwards, ensuring that the conductive block 3 remains firmly attached to the conductive foam. This effectively prevents poor contact between the conductive block 3 and the conductive foam during testing, ensuring the normal progress of the test.

[0026] like Figure 4 As shown, multiple insertion rods 20 are evenly fixedly installed at the bottom of the adjustment knob 19, and multiple insertion holes 21 are evenly opened at the top of the strip box 8. The bottom end of the insertion rod 20 extends into the insertion hole 21. The advantage of this design is that when the adjustment knob 19 is pulled upward, it will cause the insertion rod 20 to move out of the insertion hole 21. At this time, the adjustment knob 19 is in the unlocked state, and the tester can directly rotate the adjustment knob 19 to perform adjustment operations. When the adjustment knob 19 is released, under the action of gravity, the adjustment knob 19 will automatically move downward, which will cause the insertion rod 20 to automatically insert into the insertion hole 21, fixing the adjustment knob 19 so that it cannot be rotated. Thus, during use, it can effectively prevent the distance between the two conductive blocks 3 from changing automatically, making it stable and reliable during use.

[0027] like Figure 1and Figure 2 As shown, a horizontal guide rod 22 is fixedly installed on the inner side wall of the U-shaped frame 4, and the two moving blocks 6 are slidably sleeved on the horizontal guide rod 22. Through the cooperation of the horizontal guide rod 22, the two moving blocks 6 can only move horizontally and will not rotate with the bidirectional lead screw 5, thus playing a horizontal guiding role and providing good stability during use.

[0028] like Figure 1 As shown, an insulating pad 23 is fixed to the top of the test bench 1. The use of the insulating pad 23 further improves the safety of the device.

[0029] like Figure 1 As shown, multiple support legs are evenly fixed to the bottom of the test platform 1, and each support leg has a caster wheel 24 fixed to its bottom end. The caster wheel 24 allows the tester to easily move and adjust the position of the device by pushing it directly.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
