[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] According to an embodiment of the present invention, a testing machine is provided. Figures 1 to 6, including: a base 1, a fixed frame 2 is arranged on the base 1, a movable plate 3 is movably connected in the fixed frame 2, a force-applying structure 4 for impacting the sample material is arranged on the movable plate 3, and a clamping structure 5 for clamping the sample material is arranged on the base 1 corresponding to the force-applying structure 4; a shielding structure 6 for blocking the splashing of debris, one end of the shielding structure 6 is connected to the movable plate 3, and the other end of the shielding structure 6 is connected to the base 1; when the movable plate 3 moves, the shielding structure 6 is telescopically arranged along the moving direction of the movable plate 3; a protective door 7 is arranged on the base 1, and the base 1, the fixed frame 2, the movable plate 3, the shielding structure 6 and the protective door 7 together enclose a test space 8 for testing the sample material; the protective door 7 is used to open or close the test space 8. At the beginning of the test, the protective door 7 is opened, the sample material is placed on the clamping structure 5, and the protective door 7 is closed after the sample material is fixed. The movable plate 3 is controlled to drive the force structure 4 to move in the direction of the clamping structure 5, and the shielding structure 6 is compressed along the moving direction of the movable plate 3. The movable plate 3 moves to the force structure 4 to contact the sample material, and the force structure 4 applies pressure to the sample material to break the sample material, and the fragments are splashed into the test space 8. The test is completed. After the test is completed, the movable plate 3 moves back to its original position, and the shielding structure 6 is also stretched in the direction of the movable plate 3 moving back to its original position. Through the setting of the shielding structure 6, even when the movable plate 3 is moving, the shielding structure 6 can be stretched and retracted in the moving direction of the movable plate 3, and a closed test space 8 can always be formed, and the fragments splashed during the test are collected in the test space 8, thereby ensuring the safety of the test personnel and preventing damage to the instrument.

[0029] Specifically, see Figures 1 to 3 The fixed frame 2 of this embodiment includes a first fixed frame 21 and a second fixed frame 22. The first fixed frame 21 is provided with a first slide rail 23, and the second fixed frame 22 is provided with a second slide rail. The two ends of the movable plate 3 are slidably connected with the first slide rail 23 and the second slide rail respectively. The base 1, the movable plate 3, the first fixed frame 21, the second fixed frame 22, the shielding structure 6 and the protective door 7 together enclose the test space 8. The movable plate 3 moves along the direction of the clamping structure 5 on the first slide rail 23 and the second slide rail until the force structure 4 impacts the sample material, so that the sample fragments are scattered in the test space 8. In this way, the test space 8 changes continuously with the sliding of the movable plate 3, but it does not affect the airtightness of the test space 8. The structure is simple and the safety is high.

[0030] Specifically, the first fixed frame 21 of the present embodiment is provided with a third slide rail 24, the second fixed frame 22 is provided with a fourth slide rail, and the two ends of the shielding structure 6 are slidably connected to the third slide rail 24 and the fourth slide rail respectively. When the movable plate 3 slides on the first slide rail 23 and the second slide rail, the shielding structure 6 also slides on the third slide rail 24 and the fourth slide rail along the sliding direction of the movable plate 3, and the shielding structure 6 stretches or contracts. In this way, the shielding structure 6 can always stretch or contract along with the sliding of the movable plate 3, and the test space 8 is always closed, which effectively blocks the splashing of fragments generated when the sample breaks, thereby ensuring safety during the test.

[0031] Specifically, see Figure 4 In this embodiment, a receiving groove 11 for receiving the shielding structure 6 is provided on the base 1 corresponding to the shielding structure 6, and the receiving groove 11 is recessed in the base 1. At the beginning of the test, the movable plate 3 slides toward the clamping structure 5, the shielding structure 6 moves along the moving direction of the movable plate 3, and the receiving groove 11 receives part of the shielding structure 6. After the test is completed, the movable plate 3 moves back to its original position, and the shielding structure 6 in the receiving groove 11 also moves back to its original position along the moving direction of the movable plate 3. In this way, the shielding structure 6 will not block the moving stroke of the movable plate 3, so that the test is completed smoothly, and the test space 8 is always closed, which enhances the safety of the test.

[0032] Specifically, the movable plate 3 of the present embodiment is further provided with a first driving module for driving the movable plate 3, and the protective door 7 is further provided with a second driving module for driving the protective door 7 to open and close. The test machine also includes a control module, and the control module is connected to the first driving module and the second driving module by signal. At the beginning of the test, the control module operates the second driving module to open the protective door 7, and the sample material is placed on the clamping structure 5. After the sample material is fixed, the control module operates the second driving module to close the protective door 7, and then the control module operates the first driving module. The first driving module drives the movable plate 3 to drive the force structure 4 to move toward the clamping structure 5. After the force structure 4 impacts and breaks the sample material, the control module operates the first driving module, and the first driving module drives the movable plate 3 to return to its position. The control module operates the second driving module to open the protective door 7, collect the sample material fragments, and the test is completed. In this way, there is no need to manually control the sliding position of the movable plate during the test, and the operation is convenient. It prevents the protective door from opening during the test to cause the fragments to splash out of the test space 8, avoids injuries to the test personnel, and reduces safety hazards.

[0033] Specifically, see Figure 5In this embodiment, the end of the force-applying structure 4 that contacts the sample material is an arc-shaped structure, and the end of the clamping structure 5 that contacts the sample material is an arc-shaped structure. In this way, when the sample material is placed on the arc-shaped structure of the clamping structure 5 and the force-applying structure 4 impacts the sample material, the force-bearing area of ​​the sample material is large due to the setting of the arc-shaped structure, and various test requirements such as bending resistance and folding resistance can be met.

[0034] Specifically, a dustproof structure is provided on the fixed frame 2 of this embodiment. The dustproof structure has a smooth surface, is not easy to be attached with flying debris, and is convenient for observing and collecting the debris.

[0035] Specifically, the protective door 7 of this embodiment is a transparent structure. The protective door 7 of this embodiment can be set as a tempered glass door, which can prevent the protective door 7 from being damaged by flying debris and does not affect the test personnel's observation of the test process.

[0036] Specifically, see Figure 6 The shielding structure 6 of this embodiment includes a plurality of shielding parts 61, and the plurality of shielding parts 61 are connected in sequence, and two adjacent shielding parts 61 are relatively rotatably connected. When the shielding structure 6 moves toward the clamping structure 5 along with the movable plate 3, the two adjacent shielding parts 61 rotate toward each other to achieve compression of the shielding structure 6; when the shielding structure 6 moves in the returning direction along with the movable plate 3, the two adjacent shielding parts 61 rotate toward each other to achieve stretching of the shielding structure 6. With this arrangement, the extension and retraction of the shielding structure 6 is more convenient, and the test space 8 can be well sealed, and debris will not splash out of the test space 8 to cause personal injury. Specifically, the shielding structure 6 of this embodiment can be set to a soft material, such as cloth.

[0037] Many other changes and modifications can be made without departing from the concept and scope of the utility model. It should be understood that the utility model is not limited to a specific embodiment, and the scope of the utility model is defined by the appended claims.
