[0007] Further, the sample positioning units on the bottom plate are arranged in matrix.
[0008] Further, the first through hole is arranged at the center position in the front-rear direction of the sample groove, the number of the second through holes in any one positioning groove is two, and the second through holes are arranged at the corner positions of the positioning groove.
[0009] Further, the bottom plate is composed of 304 stainless steel material.
[0010] Further, the positioning center is extended above the first through hole.
[0011] Compared with the prior art, the effect of the utility model is positive and obvious. In the single sample positioning structure, the positioning block and the positioning center are added according to the sample notch shape, so that various shape size samples can be positioned according to the center, and the accuracy of the test is ensured; the anti-reverse structure is added to the first mounting hole, the second mounting hole, the third mounting hole and the fourth mounting hole, manual placing operation is simplified, and errors are not easy to occur. Residual alcohol can flow away through the first through hole and the second through hole, so as to prevent the test result from being affected, and the first through hole and the second through hole can also play a weight reduction role.

[0012] Figure 1 It is a top view schematic diagram of a sample placing box for an automatic pendulum impact testing machine.
[0013] Figure 2 It is a partial enlarged schematic diagram. Figure 1
[0014] Figure 3 It is a three-dimensional schematic diagram of a sample placing box for an automatic pendulum impact testing machine. DETAILED DESCRIPTION
[0015] The utility model is further described below in combination with embodiments, but the utility model is not limited to the embodiments, and any similar changes of the utility model should be included in the protection scope of the utility model. The use of the directions such as up, down, front, back, left, right, middle, inside and outside in the utility model is only for the convenience of clear description, and is not a limitation on the technical scheme of the utility model.
[0016] As Figures 1-3 The utility model discloses a sample placing material box for automatic pendulum impact testing machine, including bottom plate 1, the left front side, right front side, left rear side, right rear side of bottom plate 1 are provided with first mounting hole 2, second mounting hole 3, third mounting hole 4 and fourth mounting hole 5 respectively, the center distance of first mounting hole 2 and second mounting hole 3 is equal to the center distance of third mounting hole 4 and fourth mounting hole 5, and the center distance of first mounting hole 2 and third mounting hole 4 is greater than or less than the center distance of second mounting hole 3 and fourth mounting hole 5.
[0017] Further, the sample positioning units 6 on the bottom plate 1 are arranged in a matrix.
[0018] Further, the first through hole 11 is arranged at the center position in the front-back direction of the sample groove 8, and the number of the second through holes 12 in any one positioning groove 9 is two, which are arranged at the corner positions of the positioning groove 9.
[0019] Further, the bottom plate 1 is composed of 304 stainless steel material, which has good corrosion resistance to alcohol.
[0020] Specifically, the sample groove 8 can be composed of multiple small grooves arranged at intervals or a large groove.
[0021] The working principle of the embodiment is as follows:
[0022] The residual alcohol can flow away through the first through hole 11 and the second through hole 12 when the material box is taken out from the low-temperature alcohol, preventing the influence on the test results. The first through hole 11 and the second through hole 12 also play a role in weight reduction. The material box is placed and installed into the testing machine through the first mounting hole 2, the second mounting hole 3, the third mounting hole 4, and the fourth mounting hole 5.
