They have excellent elasticity and attenuation characteristics. They can withstand loads, isolate, attenuate vibrations, reduce noise, and ensure ride comfort. They have an important impact on automobile suspension design.

[0029] The tension measuring instrument is an instrument that uses the elasticity of metal to make a scaled instrument for measuring the size of the tension. The tension measuring instrument is easy to operate and can be used in combination with a back panel to install various test racks and furniture. The tension measuring instrument is widely used in tension and compression load tests in industries such as electronics, wires and cables, light industry and textiles, hardware products, building doors and windows, power machinery, scientific research institutions, etc. With the advancement of science and technology, there are also tension measuring instruments with digital display control systems on the market, which can be used for multiple mechanical tests such as stretching, compression, bending, peeling, tearing, shearing, puncturing, low-profile fatigue, etc. of different materials. This type of tension measuring instrument uses the Windows operating system to dynamically display the test data curve, and the test data can be deleted and added at will. The curve operation is simpler and easier, and the curve traversal, superposition, separation, scaling, printing and other full electronic display monitoring can be performed anytime and anywhere. The tension measuring instrument 12 and the rubber part 14 are both prior art and will not be repeated here.

[0030] During specific use, the pulling device can test the pulling force of the rubber piece by pulling it, and the detection device can detect the rubber piece when the pulling device pulls it.

[0031] In summary, by setting up a pulling device and a detection device, the pulling device can be used to pull the rubber part to test its tension, and the detection device can be used to detect the rubber part when the pulling device pulls it. Compared with the prior art, it has the characteristics of mutual cooperation between structures, easy use and simple structure.

[0032] As shown in the figure, a base 30 is fixedly installed on the top wall of the test bench 10, a limit column 13 is fixedly installed on the top wall of the base 30, a rubber part 14 passes through the limit column 13 and its cavity is placed on the top wall of the base 30, and a limit top plate 15 is provided on the side wall of the limit column 13.

[0033] The pulling plate 11 is arranged on the left and right side walls of the limiting column 13. A motor limiting plate 21 is fixedly installed on the rear wall of the right pulling plate 11, and the motor limiting plate 21 is also fixedly connected to the top wall of the test bench 10. A limiting block 17 is fixedly installed on the rear wall of the left pulling plate 11, and the limiting block 17 is also fixedly connected to the top wall of the test bench 10.

[0034] A displacement block 18 is fixedly installed on one end of the rear side wall of the two pulling plates 11 that are close to each other, a driving motor 20 is fixedly installed on the left side wall of the motor limit plate 21, and a threaded rod 19 is fixedly installed on the output end of the driving motor 20. The threaded rod 19 passes through the two displacement blocks 18 and is threadedly connected to the two displacement blocks 18, and the leftmost end of the threaded rod 19 is fixedly connected to the right side wall of the limit block 17.

[0035] A plurality of limit grooves 22 are provided on the top wall of the two pulling plates 11 at equal intervals and in an alternating manner, a tension rod 25 is movably installed in the cavity of each of the limit grooves 22, and a connecting block 26 is fixedly installed on the side wall of the two sets of limit top plates 15 away from each other.

[0036] A limit bar 23 is fixedly installed on the ends of the two groups of limit slots 22 on the top wall of the two pulling plates 11 that are away from each other, and a plurality of springs 24 are fixedly installed on the wall of the side where the two limit slots 23 are close to each other, and the plurality of springs 24 are fixedly connected to the corresponding left and right connecting blocks 26. The driving motor 20 is connected to the power supply and the switch by electrical signals. The threads on the left and right sides of the limit slot 22 are in opposite states.

[0037] During specific use, when the staff inserts the rubber part 14 into the side wall of the limiting column 13, the base 30 can block a part of the bottom wall surface of the cavity of the rubber part 14, and use the pulling device for work. Then the staff can install the limiting top plate 15 so that the limiting top plate 15 is located above the rubber part 14 and fits with the rubber part 14 to limit the rubber part 14. In the process of installing the rubber part 14, the staff needs to manually position multiple tension rods 25 in the lower cavity of the rubber part 14. The spring 24 has the force to pull the tension rod 25 toward the limiting strip 23 through the connecting block 26, and can also limit the tension rod 25 through the limiting groove 22, so that the tension rod 25 is fit with the cavity wall surface of the rubber part 14. There is no specification limit, and the motor limiting plate 21 can limit the drive motor 20 The driving motor 20 and the limit block 17 can limit the threaded rod 19. When the output end of the driving motor 20 rotates, the threaded rod 19 can be driven to rotate. The rotation of the threaded rod 19 can drive the two displacement blocks 18 to move to positions away from each other through its threads. The movement of the two displacement blocks 18 can drive the two pulling plates 11 to move. The movement of the two pulling plates 11 can drive the two groups of tension rods 25 away from each other. When the two groups of tension rods 25 are away from each other, the side of the rubber part 14 can be pulled for tension testing. The driving force of the driving motor 20 is small, and it is difficult to rotate after encountering a certain resistance. The driving force of the driving motor 20 can just test the qualified range of the rubber part 14, so as to cooperate with the pulling device and the detection device to perform tension testing.

[0038] In summary, by setting the base 30, the test bench 10, the pulling plate 11, the limiting column 13, the rubber part 14, the limiting top plate 15, the limiting block 17, the displacement block 18, the threaded rod 19, the drive motor 20, the motor limiting plate 21, the limiting groove 22, the limiting strip 23, the spring 24, the tension rod 25 and the connecting block 26, the tension of the rubber part 14 can be tested by rotating the output end of the drive motor 20, and the driving force of the drive motor 20 is set so that the drive motor 20 can just test the qualified range of the rubber part 14, and multiple tension rods 25 can be fitted with the inner side wall of the cavity of rubber parts 14 of different specifications so that this structure is not limited by the specifications of the rubber part 14, and it is easy to use and has a simple structure.

[0039] like Figure 5 As shown, the tension measuring instrument 12 is fixedly installed at the front side position of the top wall of the test bench 10 , and a tension block 28 is fixedly installed on the front side wall surface of each of the two pulling plates 11 .

[0040] A pull ring 27 is also fixedly mounted on the front side wall of the two tension blocks 28 . A threaded rod 19 is arranged on the top wall of the test bench 10 . The threaded rod 19 passes through the three pull rings 27 and is in a taut state.

[0041] During actual use, when the two pulling plates 11 move away from each other, the two pulling blocks 28 can be driven to move away from each other. The moving away of the two pulling blocks 28 can pull the pulling rope 29 through the pull ring 27, so that the tension measuring instrument 12 can detect the tension of the rubber part 14 through the force of the pulling rope 29.

[0042] In summary, by setting up the tension measuring instrument 12, the pull ring 27, the tension block 28 and the tension rope 29, the tension measuring instrument 12 can detect the tension of the rubber part 14 by pulling the tension rope 29 by the two tension blocks 28. It is easy to use and has a simple structure.
