Description

Technical Field

[0001] This utility model relates to the field of conductive rubber testing technology, and more specifically, to a conductive rubber endurance strength testing device. Background Technology

[0002] The conductive rubber tensile strength testing device is an instrument used to test the tensile strength of conductive rubber. It uses a structure consisting of a telescopic tube, a fixed tube, and elastic elements to stretch the conductive rubber, thereby evaluating its tensile strength. This device plays a crucial role in the production and quality control of conductive rubber, ensuring that product performance meets standards.

[0003] In existing technologies, such as the document with publication number CN214472286U, a device for testing the resistance strength of aging-resistant conductive rubber is specifically disclosed. In this device, the conductive rubber placed in the fixed tube is fixed by rotating the locking ring and squeezing the fixed tube towards the middle. However, the contact area between the end of the fixed tube and the conductive rubber is limited after bending, which can easily lead to unstable fixation. Therefore, we propose a device for testing the resistance strength of conductive rubber. Utility Model Content

[0004] This invention proposes a conductive rubber endurance strength testing device, which solves the technical problem in the prior art where the contact area between the end of the fixing tube and the conductive rubber is limited after bending, which easily leads to unstable fixing.

[0005] To address the aforementioned technical problems, this utility model proposes a conductive rubber endurance strength testing device, comprising two support plates. Each support plate has a mounting plate fixedly connected to its outer wall. Each mounting plate has an adjusting screw threaded to its top. The bottom of each adjusting screw penetrates the mounting plate and extends below it. A rubber block is rotatably connected to the bottom of each adjusting screw. Each support plate has a support groove on its top and sliding grooves on both sides. Two support rods are fixedly connected to the outer wall of each support plate. A pressure plate is located above each support plate. Two mounting grooves are formed on the side walls of each pressure plate. The tops of each support rod penetrate the mounting grooves and extend above them. A sliding sleeve is slidably connected to the outer wall of each support rod. A spring is fitted onto the outer wall of each support rod. A limit ring is fixedly connected to the outer wall of each support rod. The outer wall of the sliding sleeve is connected to the pressure plate.

[0006] Preferably, one end of the spring is fixedly connected to the sliding sleeve, and the other end of the spring is fixedly connected to the support plate.

[0007] Preferably, the outer wall of the sliding sleeve is rotatably connected to two rotating shafts, and the ends of the rotating shafts pass through the pressure plate and are fixedly connected to it.

[0008] Preferably, each of the rotating shafts has an extension plate fixedly connected to its outer wall, and the pressure plate has two limiting blocks fixedly connected to its outer wall, the limiting blocks being used to limit the extension plates.

[0009] Preferably, both the pressure plate and the inner wall of the bracket are fixedly connected with multiple anti-slip blocks, and the anti-slip blocks are all arc-shaped structures.

[0010] Preferably, the device further includes a mounting base, on the top of which two protective glass panes are fixedly connected, a motor is fixedly connected to the top of which two support plates are fixedly connected, a sliding rod is fixedly connected between the two support plates, a scale is embedded in the outer wall of the sliding rod, a bidirectional threaded rod is rotatably connected between the two support plates, the end of the bidirectional threaded rod passes through the support plate and extends to its outer side, and the output end of the motor is fixedly connected to the bidirectional threaded rod.

[0011] Preferably, two slide blocks are provided between the two support plates. Each slide block has a threaded hole on its outer wall and a sliding hole on its outer wall. The ends of the slide rods pass through the sliding holes and are slidably connected thereto. The ends of the bidirectional threaded rods pass through the threaded holes and are threadedly connected thereto. Each slide block has a support block fixedly connected to its top, and the top of each support block is fixedly connected to the corresponding support plate.

[0012] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0013] 1. In this utility model, the end of the conductive rubber is wrapped around the pressure plate. By rotating the adjusting screw, the rubber block is pushed downward to squeeze the top of the pressure plate. The pressure plate drives the sliding sleeve to slide downward along the outer wall of the support rod through the rotating shaft, so that the spring is compressed. The outer wall of the conductive rubber is clamped and fixed by the anti-sliding block inside the pressure plate and the support plate, which can increase the contact area between the structure and the conductive rubber, thereby improving the stability of the conductive rubber installation.

[0014] 2. In this utility model, by flipping the pressure plate upward, the pressure plate rotates around the pivot. This design makes it easy to wrap the conductive rubber end around the pressure plate. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0022] like Figures 2-4 As shown, a conductive rubber endurance strength testing device includes two support plates 12. Mounting plates 17 are fixedly connected to the outer walls of each support plate 12. Adjusting screws 18 are threadedly connected to the top of each mounting plate 17. The bottoms of the adjusting screws 18 penetrate the mounting plates 17 and extend below them. Rubber blocks 19 are rotatably connected to the bottoms of the adjusting screws 18. A support groove 13 is formed on the top of each support plate 12, and sliding grooves 16 are formed on both sides of each support plate 12. Two support rods 21 are fixedly connected to the outer walls of each support plate 12. A pressure plate 14 is provided above each support plate 12. Two mounting grooves 20 are formed on the side walls of each pressure plate 14. The tops of the support rods 21 penetrate the mounting grooves 20 and extend above them. The outer walls of the support rods 21 are slidable. A sliding sleeve 22 is connected to the outer wall of the support rod 21, and a spring 24 is fitted on each of the two outer walls. One end of the spring 24 is fixedly connected to the sliding sleeve 22, and the other end of the spring 24 is fixedly connected to the support plate 12. A limit ring 23 is fixedly connected to the outer wall of the support rod 21. The outer wall of the sliding sleeve 22 is connected to the pressure plate 14. By adjusting the screw 18, the rubber block 19 is pushed downward to squeeze the top of the pressure plate 14. The pressure plate 14 drives the sliding sleeve 22 to slide downward along the outer wall of the support rod 21 through the rotating shaft 25, so that the spring 24 is compressed. The outer wall of the conductive rubber is clamped and fixed by the anti-slip block 15 inside the pressure plate 14 and the support plate 12, which can increase the contact area between the structure and the conductive rubber, thereby improving the stability of the conductive rubber installation.

[0023] like Figure 4As shown, the outer wall of the sliding sleeve 22 is rotatably connected to two rotating shafts 25, and the ends of the rotating shafts 25 pass through the pressure plate 14 and are fixedly connected to it.

[0024] like Figure 4 As shown, extension plates 27 are fixedly connected to the outer wall of the rotating shaft 25, and two limiting blocks 26 are fixedly connected to the outer wall of the pressure plate 14. The limiting blocks 26 are used to limit the extension plates 27. By setting the limiting blocks 26, the angle of the flipped pressure plate 14 can be limited, so that the pressure plate 14 and the support plate 12 remain parallel, ensuring that the end faces of the pressure plate 14 and the support plate 12 can fully contact each other, thereby stably clamping the conductive rubber.

[0025] like Figure 3 As shown, multiple anti-slip blocks 15 are fixedly connected to the inner walls of the pressure plate 14 and the bracket 13, and the anti-slip blocks 15 are all arc-shaped structures.

[0026] like Figure 1 As shown, it also includes a mounting base 1. Two protective glass panes 2 are fixedly connected to the top of the mounting base 1. The protective glass panes 2 can prevent the ends of the conductive rubber from swinging and causing injury to the observer when it breaks. A motor 3 is fixedly connected to the top of the mounting base 1. Two support plates 4 are fixedly connected to the top of the mounting base 1. A sliding rod 6 is fixedly connected between the two support plates 4. A scale 7 is embedded in the outer wall of the sliding rod 6. A bidirectional threaded rod 5 is rotatably connected between the two support plates 4. The end of the bidirectional threaded rod 5 passes through the support plate 4 and extends to its outer side. The output end of the motor 3 is fixedly connected to the bidirectional threaded rod 5. The motor 3 drives the bidirectional threaded rod 5 to rotate, so that the two sliding blocks 8 slide along the sliding rod 6 in opposite directions, so that the conductive rubber is stretched. By observing the scale 7, the tensile strength of the conductive rubber can be understood, thereby testing its endurance strength.

[0027] like Figure 1 and Figure 2 As shown, two slides 8 are provided between the two support plates 4. The outer wall of each slide 8 is provided with threaded holes 9 and sliding holes 10. The ends of the slide rods 6 pass through the sliding holes 10 and are slidably connected to them. The ends of the bidirectional threaded rods 5 pass through the threaded holes 9 and are threadedly connected to them. The top of each slide 8 is fixedly connected with a support block 11, and the top of the support block 11 is fixedly connected to the corresponding support plate 12.

[0028] Working principle: By flipping the pressure plate 14 upward, the pressure plate 14 rotates around the pivot 25, and the conductive rubber end is wrapped around the pressure plate 14. By rotating the adjusting screw 18, the rubber block 19 is pushed downward to squeeze the top of the pressure plate 14. The pressure plate 14 drives the sliding sleeve 22 to slide downward along the outer wall of the support rod 21 through the pivot 25, so that the spring 24 is compressed. The outer wall of the conductive rubber is clamped and fixed by the anti-sliding block 15 inside the pressure plate 14 and the support plate 12.

[0029] By rotating the adjusting screw 18 in the opposite direction, the sliding sleeve 22 slides upward along the support rod 21 under the elastic force of the spring 24. The sliding sleeve 22 drives the pressure plate 14 to move upward, thereby quickly disengaging from the clamping of the conductive rubber.
