Description

Technical Field

[0001] The utility model relates to the technical field of material detection, and more specifically to a tensile test detection device. Background Art

[0002] Tensile testing machines, also known as universal material testing machines, are mechanically loaded testing machines used to perform mechanical property tests on various materials, including static load, tension, compression, bending, shear, tearing, and peeling. They are suitable for testing the physical and mechanical properties of materials such as plastic sheets, pipes, profiles, plastic films, rubber, wire and cable, steel, and fiberglass. They are essential testing equipment for material development, physical property testing, teaching research, and quality control.

[0003] During material testing, there may be a phenomenon where the material breaks due to excessive tension. Since existing tensile testing machines lack a blocking mechanism, some hard materials will collapse after breaking, and the fragments that pop out can easily injure workers. Utility Model Content

[0006] A mounting hole is provided on the front of the transparent protective door, a sleeve is fixedly connected to the inner wall of the mounting hole, a T-shaped connecting rod is slidably connected to the inner wall of the sleeve, a transparent shielding plate is detachably installed on the end face of the T-shaped connecting rod, and a first connecting spring is fixedly connected to the opposite surface of the T-shaped connecting rod and the sleeve.

[0007] The solution is further that the positioning mechanism includes a concave box fixedly mounted on the upper surface of the concave seat, the inner wall of the concave box is slidably connected to a sliding block, the lower surface of the sliding block is fixedly connected to a plug rod, the bottom end of the plug rod is fixedly connected to a hemispherical block, the sliding block and the opposite surface of the concave box are fixedly connected to a reset spring, a sliding hole is provided on the upper surface of the concave seat, the surface of the plug rod overlaps with the inner wall of the sliding hole, and two positioning countersunk holes adapted to the hemispherical block are provided on the upper surface of the transparent protective door, and the surface of the hemispherical block overlaps with the inner wall of the positioning countersunk hole.

[0009] Technical effects and advantages of this utility model:

[0010] 1. When conducting a tensile test, the tensile test detection device closes the transparent protective door to block the material, which can prevent the material from splashing when the material breaks. When the material splashes, it will collide with the transparent shielding plate. The transparent shielding plate is forced to push the T-shaped connecting rod to move. At this time, the T-shaped connecting rod pushes the first connecting spring for buffering, thereby preventing the transparent shielding plate from being worn after the impact.

[0011] 2. The tensile test detection device can pull the transparent shielding plate after opening the transparent protective door. At this time, the arc surface of the T-shaped positioning block is forced to be accommodated in the T-shaped groove, and the transparent shielding plate can be directly taken out for replacement. When installing a new transparent shielding plate, the installation sleeve is put on the surface of the T-shaped connecting rod. At this time, the arc surface of the T-shaped positioning block is forced to be accommodated, and the second connecting spring is squeezed. When the position of the T-shaped positioning block is aligned with the position of the positioning port, the elastic force of the second connecting spring pushes the T-shaped positioning block into the positioning port, and the transparent shielding plate can be fixed, thereby facilitating the replacement of the transparent shielding plate.

[0021] The positioning mechanism includes a concave box 9 fixedly mounted on the upper surface of the concave seat 2, the inner wall of the concave box 9 is slidably connected to a sliding block 10, the lower surface of the sliding block 10 is fixedly connected to a plug rod 11, the bottom end of the plug rod 11 is fixedly connected to a hemispherical block 12, the sliding block 10 and the opposite surface of the concave box 9 are fixedly connected with a reset spring 13, a sliding hole is provided on the upper surface of the concave seat 2, the surface of the plug rod 11 overlaps with the inner wall of the sliding hole, and the upper surface of the transparent protective door 4 is provided with two positioning countersunk holes 14 that are compatible with the hemispherical block 12, and the surface of the hemispherical block 12 overlaps with the inner wall of the positioning countersunk hole 14.

[0022] When the transparent protective door 4 is opened, the arc surface of the hemispherical block 12 is subjected to force to push the plug rod 11 upward, and the plug rod 11 pushes the sliding block 10 to squeeze the reset spring 13. When the transparent protective door 4 is fully opened, the hemispherical block 12 is aligned with another positioning countersunk hole 14. The elastic force of the reset spring 13 can push the hemispherical block 12 into the positioning countersunk hole 14, thereby positioning the position of the transparent protective door 4. Similarly, when the transparent protective door 4 is closed, the hemispherical block 12 can position the transparent protective door 4.

[0023] A mounting hole is provided on the front of the transparent protective door 4, and a sleeve 5 is fixedly connected to the inner wall of the mounting hole. A T-shaped connecting rod 6 is slidably connected to the inner wall of the sleeve 5. A transparent baffle 7 is detachably installed on the end face of the T-shaped connecting rod 6. A mounting sleeve 15 is fixedly connected to the side of the transparent baffle 7 facing the T-shaped connecting rod 6, and the surface of the T-shaped connecting rod 6 overlaps with the inner wall of the mounting sleeve 15.

[0024] A T-shaped slot is provided on the surface of the T-shaped connecting rod 6, and a T-shaped positioning block 16 is slidably connected to the inner wall of the T-shaped slot. The T-shaped positioning block 16 and the opposite surface of the T-shaped slot are fixedly connected to a second connecting spring 17. The front and back surfaces of the T-shaped positioning block 16 are both arc-shaped, and a positioning opening is provided on the surface of the mounting sleeve 15. The surface of the T-shaped positioning block 16 overlaps the inner wall of the positioning opening.

When installing a new transparent baffle plate 7, the mounting sleeve 15 is put on the surface of the T-shaped connecting rod 6. At this time, the arc surface of the T-shaped positioning block 16 is force-received, and the second connecting spring 17 is squeezed. When the position of the T-shaped positioning block 16 is aligned with the position of the positioning port, the elastic force of the second connecting spring 17 pushes the T-shaped positioning block 16 to be inserted into the positioning port, so that the transparent baffle plate 7 can be fixed, thereby facilitating the replacement of the transparent baffle plate 7.

[0026] The T-shaped connecting rod 6 is fixedly connected to the opposite surface of the sleeve 5 with a first connecting spring 8. When conducting a tensile test, the transparent protective door 4 is closed to block the material, which can prevent the material from splashing when the material breaks. When the material splashes, it will collide with the transparent shielding plate 7. The transparent shielding plate 7 is pushed by the force to move the T-shaped connecting rod 6. At this time, the T-shaped connecting rod 6 pushes the first connecting spring 8 for buffering, thereby preventing the transparent shielding plate 7 from wear after the impact.
