[0030] The base plate 1 has two base blocks 2, one of which is fixedly connected to the base plate 1 and the other base block 2 is in sliding contact with the base plate 1.

[0031] Two L-shaped plates 3 are provided, and the two L-shaped plates 3 are fixedly connected to the top of the two base blocks 2 respectively.

Each threaded rod 4 is fitted with a threaded block 5. The threaded block 5 is connected to the threaded rod 4 by threads. Each threaded block 5 is fixedly fitted with a pressure block 6. The bottom of the two pressure blocks 6 and the top of the two base blocks 2 are fixedly connected with a protruding strip 7.

[0032] Two connecting blocks 8 are provided, and the two connecting blocks 8 are fixedly connected to the top of the two L-shaped plates 3 respectively. A rotating shaft 9 is embedded in each of the two connecting blocks 8. A prism 10 is slidably embedded in one of the rotating shafts 9 and one end of the prism 10 is fixedly connected to the end of the other rotating shaft 9. A bevel gear 11 is fixedly sleeved on the outside of the two rotating shafts 9. A bevel gear 12 is provided on one side of the two bevel gears 11 and meshes with it. The two bevel gears 12 are fixedly connected to the top of the two threaded rods 4 respectively.

[0033] A knob 13 is fixedly connected to one of the rotating shafts 9;

[0034] In this embodiment, two rotating shafts 9 and a prism 10 that can slide in the right rotating shaft 9 are designed. When in use, the rotation of the two rotating shafts 9 and the prism 10 can cause the two threaded rods 4 to rotate at the same time, thereby causing the two threaded blocks 5 and the two pressure blocks 6 to move downward at the same time. In this way, the two pressure blocks 6 can clamp and fix the two ends of the rubber strip at the same time.

[0035] In order to achieve the purpose of stable movement of threaded block 5, the device adopts the following technical solution: guide rods 14 are fixedly connected to both L-shaped plates 3. The two guide rods 14 pass through the two threaded blocks 5 respectively and slide in contact with them. The cross section of the two guide rods 14 is set as T-shaped. The guide rods 14 can make the threaded block 5 move stably.

[0036] In order to achieve the purpose of stable movement of base block 2, the device adopts the following technical solution: a limiting rod 15 is fixedly connected to the top of the base plate 1, the limiting rod 15 passes through another base block 2 and slides in contact with it, the cross section of the limiting rod 15 is set to T-shaped, and the limiting rod 15 can make the base block 2 move stably.

[0037] In order to support the prism 10, the device adopts the following technical solution: a support plate 16 is fixedly connected to the top of the base plate 1, a second rotating shaft 17 is embedded in the support plate 16, the second rotating shaft 17 is fixedly connected to the prism 10, and the second rotating shaft 17 is connected to the support plate 16 through a bearing.

[0038] To achieve the purpose of pulling, the device adopts the following technical solution: a motor 18 is fixedly connected to the top of the base plate 1, a threaded rod 19 is fixedly connected to the output shaft of the motor 18, the end of the threaded rod 19 passes through the support plate 16 and is connected to one of the base blocks 2, a threaded block 20 is sleeved on the outside of the threaded rod 19, the threaded block 20 is fixedly embedded on another base block 2, a scale 21 is fixedly provided on the top of the base plate 1, and a pointer 22 is fixedly connected to the front side of the other base block 2;

[0039] In order to reduce wear, the device adopts the following technical solution: threaded rod 4 is connected to base block 2 and L-shaped plate 3 through bearings, rotating shaft 9 is connected to connecting block 8 through bearings, and threaded rod 19 is connected to support plate 16 and base block 2 through bearings. The bearing connection can reduce wear.

[0040] The usage process of this utility model is as follows: When it is necessary to test the elasticity of the rubber strip, hold the rubber strip and place both ends of the rubber strip on the two base blocks 2. Then, turn the knob 13 to make the left rotating shaft 9 rotate, which in turn drives the prism 10 and the right rotating shaft 9 to rotate. This allows the two rotating shafts 9 to rotate simultaneously. The rotation of the two rotating shafts 9 drives the two bevel gears 11 to rotate, which in turn drives the two bevel gears 12 to rotate, which in turn drives the two threaded rods 4 to rotate. The rotation of the two threaded rods 4 drives the two threaded blocks 20 to move downward, which allows the two pressure blocks 6 to move downward simultaneously. In this way, the two pressure blocks 6 can clamp and fix the two ends of the rubber strip at the same time. Thus, this device can fix the two ends of the rubber strip at the same time, which can reduce the time spent on fixing before testing.

[0041] After fixing, control motor 18 to work and make threaded rod 19 rotate. The rotation of threaded rod 19 drives threaded block 20 to move to the right, thereby pulling the base block 2, L-shaped plate 3, connecting block 8, pressure block 6, threaded rod 4 and other components on the right to move to the right, so that the rubber strip can be pulled, and the elasticity test of the rubber strip can be performed.

[0042] Before the elasticity test, you can first look at what mark the pointer 22 on the right base block 2 points to on the scale 21. Then, when you pull the rubber strip, you can see what mark the pointer 22 points to on the scale 21 after the rubber strip is pulled. Then, you can subtract the previous mark from the next mark to know how long the rubber strip is pulled. Based on the length of the pull, you can determine whether the rubber strip is qualified.

[0043] After the test is completed, control motor 18 to reverse so that the base block 2 and other components on the right side move to the left to reset. Then, turn knob 13 in the opposite direction to move the two pressure blocks 6 upward, thereby releasing the fixation of the rubber strip. Then the rubber strip can be removed, and the test can continue on the same principle.

[0044] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
