Technical Field
[0001] This utility model relates to the field of tensile testing equipment technology, and in particular to a universal material tensile testing machine with protective functions. Background Technology
[0002] A universal tensile testing machine is a mechanically applied testing machine used to test the mechanical properties of various materials. To determine the tensile strength of a material, it is slowly pulled under an axial force until it breaks. Traditional universal tensile testing machines often lack protective structures, and when the tested material accidentally breaks, fragments may fly out, potentially injuring workers. This paper proposes a universal tensile testing machine with protective features. An openable protective cover structure protects the outside of the machine, preventing fragments from flying out. Simultaneously, a protective net is installed inside the cover to cushion and absorb any flying fragments, eliminating the impact force. Utility Model Content

[0028] Reference Figure 4 and Figure 5The tensile testing mechanism includes a housing 9, which is mounted on top of a base 1. Lifting screws 10 are connected through both sides of the housing 9, and a movable crossbeam 11 is threaded onto the outer side of the lifting screws 10. The movable crossbeam 11 moves up and down by rotating the lifting screws 10. A tensile sensor 12 is installed at the bottom of the movable crossbeam 11, and an upper clamp 13 is installed at the bottom of the tensile sensor 12. The tensile sensor 12 is used to record data during material measurement. A lower clamp 14 is installed at the bottom of the housing 9, and right-angle steering boxes 15 are installed on both sides of the top of the housing 9. Between the right-angle steering box 15 is a lifting transmission motor 16, which is used to drive the right-angle steering box 15, so that the right-angle steering box 15 drives the lifting screw 10, so that the lifting screw 10 rotates synchronously and smoothly controls the lifting and lowering of the moving crossbeam 11. The upper clamp 13 and the lower clamp 14 are positioned correspondingly and are used to clamp the material to be tested. The housing 9 is provided with a "U" shaped structure. The upper clamp 13 moves up and down along the lifting screw 10, and the lower clamp 14 is fixedly installed at the bottom of the housing 9.
[0029] Reference Figure 3 , Figure 6 and Figure 7 The rotating plate 5 is made of transparent material, and the rotating grooves 4 are symmetrically arranged in a linear array inside the protective cover 2. The rotating blocks 6 are linearly arranged on one side of the rotating plate 5.

One end of the material to be tested is fixed to the lower clamp 14, and the other end is fixed to the upper clamp 13. Next, the moving plate 18 is moved upward to fix the multiple hooks 17 installed at the bottom of the top cover 3, allowing the protective net 19 to cover the outside of the casing 9. Then, the fixing plate 8 is pulled to close the rotating plates 5, and the bolts are installed corresponding to the fixing plate 8 to fix the rotating plates 5. Then, the lifting drive motor 16 is started to move the moving crossbeam 11 upward, applying tension to the test material. The tension sensor 12 at the bottom of the moving crossbeam 11 records the tension data. When the test material breaks accidentally, the broken fragments fly out and are blocked by the protective net 19 covering the outside of the casing 9, buffering the impact force of the fragments. Then, the protective cover 2 and the rotating plates 5 further block the fragments, effectively protecting them.
