For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] The present invention provides the following technical solutions:

[0026] Embodiment 1

[0027] Combined with Figures 1 to 5 , a metal tensile testing machine with a protection function includes a test machine body 1, a protection mechanism 2 is arranged outside the test machine body 1, and a driving mechanism 3 is arranged on one side of the protection mechanism 2;

[0028] The protection mechanism 2 includes a support plate 21, the support plate 21 is fixedly connected to the outside of the test machine body 1, a threaded cylinder 22 is rotatably connected inside the support plate 21, the threaded cylinder 22 is threadedly connected to a threaded rod 23, one end of the threaded rod 23 away from the threaded cylinder 22 is fixedly connected to a fixed seat 27, a protective cover 29 is fixedly connected to one side of the fixed seat 27, a worm gear 24 is fixedly connected to the outer wall of the threaded cylinder 22, a worm 25 is engaged with the outer ring of the worm gear 24, a connecting plate 26 is fixedly connected to the side of the support plate 21 away from the test machine body 1, and a limit long plate 28 is fixedly connected to the side of the support plate 21 close to the test machine body 1.

[0029] Further, a sliding opening is formed inside the fixed seat 27. The fixed seat 27 is slidably connected to the outer side of the limit long plate 28 through the formed sliding opening, enabling the fixed seat 27 to move stably.

[0030] Further, a rotating hole is formed inside the connecting plate 26. The worm 25 passes through the formed rotating hole and rotates, serving the purpose of supporting the worm 25.

[0031] Further, there are four protective covers 29. Two of the four protective covers 29 form a group, facilitating the simultaneous protection of the front and the back of the test machine body 1.

[0032] Embodiment 2

[0033] Refer to Figures 1 to 5 and, on the basis of Embodiment 1, it is further obtained that the driving mechanism 3 includes a support frame 31. The support frame 31 is fixedly connected to the outer side of the test machine body 1. A motor 32 is fixedly connected to the inner side of the support frame 31. A bevel gear A33 is arranged on one side of the motor 32. The outer ring of the bevel gear A33 is meshed with a bevel gear B34, facilitating the achievement of the purpose of stable driving.

[0034] Further, the output end of the motor 32 is fixedly connected with an output shaft. The bevel gear A33 is fixedly connected to the outer wall of the output shaft. Under the action of the output shaft, the bevel gear A33 can be driven to rotate.

[0035] Further, the bevel gear B34 is fixedly connected to the outer wall of the worm 25, enabling the bevel gear B34 to drive the worm 25 to rotate.

[0036] During the actual operation process, when this device is used, first, the staff can start the motor 32 to work, so that the output shaft of the motor 32 can drive the bevel gear A33 to rotate. The bevel gear A33 drives the worm 25 to rotate through the transmission of the bevel gear B34, and thus the purpose of driving can be achieved, facilitating the further achievement of the driving purpose. At the same time, the protective cover 29 can move synchronously, facilitating the staff to operate and use, and enhancing the practicability of the device.

[0037] When the worm 25 rotates, it drives the meshing worm wheel 24 to rotate. The worm wheel 24 drives the threaded barrel 22 to rotate. Since the threaded barrel 22 and the threaded rod 23 are in threaded connection, the rotational motion of the threaded barrel 22 is converted into the linear motion of the threaded rod 23, enabling the threaded rod 23 to drive the protective cover 29 to move through the fixed seat 27. At the same time, the fixed seat 27 can slide and be limited outside the limit long plate 28, allowing the protective cover 29 to move stably. As a result, the left protective cover 29 and the right protective cover 29 approach each other. Thus, during the test, the protective cover 29 can perform a protective function, reducing the risks faced by the operator. When the clamping device suddenly loosens or breaks, causing the sample to fly out or the fixture to shift, it will not cause harm to the operator, enhancing the safety performance. Meanwhile, the test situation of the testing machine body 1 can be observed through the protective cover 29.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Without more limitations, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
