[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 ,Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution: a tensile testing device after stator welding, including an operating table 1, a tensile testing device body 2 fixedly connected to the top of the operating table 1, movable grooves 3 on both sides of the tensile testing device body 2, a protective plate 4 slidably connected to one end of the tensile testing device body 2, movable blocks 15 fixedly connected to both sides of the protective plate 4, the interior of the movable groove 3 slidably connected to the surface of the movable block 15, connecting rods 5 fixedly connected to both sides of one end of the protective plate 4, a sliding groove 6 inside the sliding groove 6, a transmission block 7 slidably connected inside the sliding groove 6, an installation groove 8 on the surface of the transmission block 7, three first springs 9 fixedly connected inside the installation groove 8, one side of the first spring 9 fixedly connected to a stop button 10, first fixing blocks 11 fixedly connected to the bottom ends of both sides of the tensile testing device body 2, the surface of the transmission block 7 slidably connected to the interior of the first fixing block 11, tensile testing... The top of both sides of the main body 2 of the device is fixedly connected to a second fixing block 20. After the item to be tested is placed inside the main body 2 of the tensile testing device, the abutment button 10 is pressed to return the abutment button 10 to the inside of the mounting slot 8. Then, the transmission block 7 is moved to move the transmission block 7 out of the inside of the second fixing block 20, thereby releasing the limit between the main body 2 of the tensile testing device and the protective plate 4. Then, the protective plate 4 is pulled down to move the transmission block 7 into the inside of the first fixing block 11. The elasticity of the first spring 9 automatically drives the abutment button 10 to lift up, so that the abutment button 10 locks into the second fixing block 20. This can keep the protective plate 4 stable at the top of the operating table 1. When the main body 2 of the tensile testing device performs a tensile test on the item, if the item fails to be tested and the welded part breaks, iron filings will fly out. By setting the protective plate 4, not only can the safety of the testing process be ensured, but the staff can also be effectively protected from the injury of flying iron filings.

[0024] Reference Figure 2 , Figure 5 and Figure 6 As shown in this embodiment: both ends of the moving groove 3 are provided with first sliding grooves 12, and both ends of the moving block 15 are fixedly connected with first sliders 13. The surface of the first slider 13 is slidably connected to the inside of the first sliding groove 12. By making the first sliding groove 12 slide inside the first slider 13, the movement of the protective plate 4 on the surface of the tensile testing device body 2 can be more stable, limiting the movement position of the tensile testing device body 2 and providing guidance for the movement of the tensile testing device body 2.

[0025] Reference Figure 5As shown in this embodiment: three rotating shafts 14 are rotatably connected to the interior of both ends of the first slider 13. The surface of the rotating shaft 14 is rotatably connected to the interior of the first slide groove 12. By installing the rotating shaft 14 inside the first slider 13, the movement of the protective plate 4 can be made smoother, making it easier for the staff to move the protective plate 4.

[0026] Reference Figure 2 As shown in this embodiment: the top end of the moving block 15 is fixedly connected to a second spring 16, and the other end of the second spring 16 is fixedly connected to the top end of the moving groove 3. By setting the second spring 16, after the elasticity of the second spring 16 releases the limit between the transmission block 7 and the first fixed block 11, it will automatically pull the moving block 15, so that the moving block 15 drives the protective plate 4 to move and automatically reset the protective plate 4, providing convenience for the user.

[0027] Reference Figure 4 As shown in this embodiment: the surface of the abutment button 10 is fixedly connected to the limiting block 17, and the surface of the limiting block 17 is slidably connected to the interior of the mounting groove 8. By setting the limiting block 17, the limiting block 17 can restrict the movement position of the abutment button 10, so that the abutment button 10 is stable inside the mounting groove 8, and the abutment button 10 will not come out due to human error or excessive elasticity of the first spring 9.

[0028] Reference Figure 4 As shown in this embodiment: the top and bottom of the sliding groove 6 are provided with second sliding grooves 18, and the top and bottom of the transmission block 7 are fixedly connected with second sliders 19. The surface of the second sliders 19 is slidably connected to the inside of the second sliding grooves 18. By moving the second sliders 19 inside the second sliding grooves 18, the movement position of the transmission block 7 can be restricted, and the movement of the transmission block 7 can be guided, making the movement of the transmission block 7 more stable and preventing shaking.

[0029] Reference Figure 6 As shown in this embodiment, a shock-absorbing pad 21 is installed at the bottom of the protective plate 4. By setting the shock-absorbing pad 21, the protective plate 4 can be effectively damped when it falls. This damping mechanism can significantly reduce the impact force generated when the protective plate 4 contacts the surface of the operating table 1, thereby reducing the noise and vibration that may be generated.

[0030] Working principle: Step 1, place the item to be tested inside the tensile testing device body 2, press the abutment button 10 to return it to the inside of the mounting slot 8, and prepare for the next operation. Move the transmission block 7 to move it out from the inside of the second fixing block 20, thereby releasing the limiting relationship between the tensile testing device body 2 and the protective plate 4, and providing conditions for the opening of the protective plate 4.

[0031] Step 2: Pull down the protective plate 4 so that it covers the top of the tensile testing device body 2. During the pulling down process, move the transmission block 7 into the interior of the first fixed block 11. Use the elasticity of the first spring 9 to automatically drive the abutment button 10 to lift up, so that the abutment button 10 engages with the second fixed block 20, thereby stably fixing the protective plate 4 to the top of the operating table 1.

[0032] Step 3: Activate the tensile testing device body 2 to conduct a tensile test on the item. During the test, if the item fails and the welded part breaks, iron filings will fly out. At this time, the protective plate 4 can effectively prevent iron filings from flying and protect the safety of the staff.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
