[0023] like Figure 1 Shown to Figure 2As shown, the tongue depressor compression test device is used in conjunction with a tensile testing machine and includes a base 100, a placement piece 200 and a limit block 300; the base 100 is a structure with a certain length, and the base 100 is arranged at the bottom of the tensile testing machine; the placement piece 200 is a structure with a certain height, and the placement piece 200 is slidably arranged on the top of the base 100, and there are two placement pieces 200, and the tops of the two placement pieces 200 are both provided with a groove, and the groove is located on the side of the placement piece 200 close to the other placement piece 200, which is suitable for placing the tongue depressor; the limit block 300 is slidably arranged on the top of the base 100, and there are two limit blocks 300, and the limit block 300 is located on the side of the placement piece close to one end of the base 100, so that the two placement pieces 200 and the two limit blocks 300 become symmetrical, and a latch 310 is provided on the limit block 300, and the limit block 300 is fixed by the latch 310.
[0024] Specifically, a base 100 is provided to connect the tensile machine. The base 100 is provided at the bottom of the tensile machine and is connected to the bottom of the tensile machine. In order to place the tongue depressor, a placement piece 200 is provided on the base 100. The placement piece 200 is slidably provided on the top of the base 100. Because the tongue depressor has a certain length, two placement pieces 200 are required. The tops of the two placement pieces 200 are both provided with grooves. The grooves are located on one side of the placement piece 200 close to the other placement piece 200, so that the two ends of the tongue depressor are placed on the two placement pieces 20. 0, such a setting is placed in the groove of 0, and the tongue depressor moves during the pressure application process. There is a preset distance between the two placement pieces 200, so that the middle part of the tongue depressor is suspended in the air and can be subjected to pressure to test the pressure resistance of the tongue depressor. In order to avoid the two placement pieces 200 sliding when the tensile machine applies pressure, a limit block 300 is set on the opposite side of the two placement pieces, and a bolt 310 is set on the limit block 300. The limit block 300 is fixed by the bolt 310. When the tensile machine applies pressure, the placement piece 200 moves, resulting in inaccurate experiments.
[0025] In a possible implementation, the two placement pieces 200 are disposed along the length direction of the base 100 , and the two placement pieces 200 are equal in length.
[0026] Specifically, such as Figure 1 As shown, since the tongue depressor is placed along the length direction of the base 100, the two placement pieces 200 are also set along the length direction of the base 100. Moreover, in order to ensure that the force points of the tongue depressor can be evenly stressed when pressure is applied to the tongue depressor, it is necessary to ensure that the tongue depressors are on the same horizontal plane, because the two placement pieces need to be at the same height.
[0027] In a possible implementation, a through hole is provided on the limit block 300 , and the through hole is arranged perpendicular to the base 100 ; a latch 310 is provided on the limit block 300 , and the latch 310 passes through the through hole and is latched with the base 100 .
[0028] Specifically, such as Figure 2 As shown, because the limit block 300 can also slide back and forth on the top of the base 100, in order to enable the limit block 300 to play a limiting role, a latch 310 is set on the limit block 300, and a through hole is opened on the limit block 300. The latch 310 passes through the through hole and is connected to the base 100 to achieve limiting.
[0029] In a possible implementation, a measuring piece 400 is further included. The measuring piece 400 is arranged along the length direction of the base 100 , and the measuring piece 400 is arranged on the front wall of the base 100 .
[0030] Specifically, in order to determine the required distance between the two placement pieces and the test center point of the tongue depressor, the limit block 300 is adjusted to fix the distance, and then the experiment is started. The measuring piece 400 is set. Because the tongue depressor is set along the length direction of the base 100, the measuring piece 400 is also set along the length direction of the base 100. For the convenience of the experimenters, the measuring piece 400 is set on the front wall of the base 100.
[0031] In a possible implementation, a fixing member 500 is further included, and the fixing member 500 is disposed in the middle portion of the bottom of the base 100 .
[0032] Specifically, in order to fix the base 100 on the tensile testing machine, a fixing member 500 is provided at the middle position of the bottom of the base 100 , and the fixing member 500 cooperates with the connector 600 at the bottom of the tensile testing machine to fix the base 100 on the tensile testing machine.
[0033] In one possible implementation, the fixing member 500 includes a support block 510 and a connecting rod 520; the support block 510 is arranged in the middle part of the bottom of the base 100; the connecting rod 520 is arranged at the bottom of the support block 510, and a through hole is opened on the connecting rod 520, and the through hole is arranged perpendicular to the connecting rod 520.
[0034] Specifically, such as Figure 1As shown, the specific structure of the fixing member 500 includes a support block 510 and a connecting rod 520. The support block 510 is used to support the base 100 to the top of the connector 600 at the bottom of the tensile machine. The connecting rod 520 is provided because the connector 600 is an internally hollow structure. The diameter of the provided connecting rod 520 is smaller than the diameter of the connector 600, so that the connecting rod 520 can enter the connector 600. In order to better achieve fixation, a through hole is opened on the connecting rod 520. The position of the through hole ensures that after the connecting rod 520 is inserted into the connector 600, it is at the same position as the national control position on the connector 600. Then, a fixing rod is used to pass through the through hole to play a fixing role.
[0035] In one possible implementation, a groove 110 is provided in the length direction of the base 100, and an inner slide rail is provided inside the groove 110; the bottoms of the two placement pieces 200 and the bottoms of the two limit blocks 300 are both provided with outer slide rails, and the inner slide rails are adapted to the outer slide rails.
[0036] Specifically, in order to enable the placement piece 200 and the limit block 300 to slide along the base 100 and adjust the distance, a groove 110 is opened on the base 100, an inner slide rail is set in the groove 110, the placement piece 200 and the limit block 300 are set above the groove 110, and an outer slide rail is set at the bottom of the placement piece 200 and the limit block 300. The inner slide rail is combined with the outer slide rail to enable the placement piece 200 and the limit block 300 to slide on the base 100.
[0037] In a possible implementation, the length of the inner slide rail is smaller than the length of the base 100 .
[0038] Specifically, in order to prevent the limiting block 300 from being separated from both ends of the base 100 , the length of the inner slide rail is made shorter than the length of the base 100 , so that both ends of the base 100 are closed.
[0039] In a possible implementation, the base 100 and the limiting block 300 are both cuboids, and the placement piece 200 is a cylinder.
[0040] Specifically, for overall aesthetics, the base 100 and the limiting block 300 are both rectangular parallelepipeds, and the placement piece 200 is a cylinder.
[0041] When using this application, the base 100 is connected to the bottom of the tensile testing machine through a fixing part, the tongue depressor is placed on the placement part 200, the distance between the two placement parts is adjusted, and the two placement parts 200 are limited by the limit block 300. Then, pressure is applied to the tongue depressor through the tensile testing machine to start the test. The tensile testing machine is connected to a computer, and the computer automatically records the measured experimental results and force value curve to complete the experiment.
[0042] The present application is provided with a base 100, a placement piece 200, a limit block 300, a measuring piece 400 and a fixing piece 500. The placement piece 200, the limit block 300 and the measuring piece 400 are all provided on the base 100. The base 100 plays a supporting role, and the fixing piece 500 plays a role of connecting with the tensile testing machine. By placing the tongue depressor on the placement piece 200, the tensile testing machine applies pressure on the tongue depressor to obtain experimental data and complete the experiment. The present application can test the compression resistance value of the tongue depressor through the above settings, which solves the problem that there is no good solution in real life and the compression resistance value of the tongue depressor cannot be obtained. Further, the quality of the tongue depressor cannot be guaranteed.
