[0037] Bolts 15 are symmetrically provided on the outer surface of the upper end of the slide 13, and a clamping plate 14 is threadedly connected to the outer surface of the bolt 15. The lower end of the clamping plate 14 is arc-shaped. The clamping plate 14 is threadedly connected to the slide 13 through the bolts 15, and a steel bar 16 is provided between the clamping plate 14 and the slide 13.

[0038] By adopting the above technical solution, the box body 11 is supported by the legs 10. When the tensile strength of the steel bar 16 is tested by the tensile component 1, the two ends of the steel bar 16 are placed on the slide 13, and then the clamping plate 14 is threadedly connected to the slide 13 through the bolts 15 to clamp and fix the steel bar 16. At this time, the hydraulic rod 18 is started, and the hydraulic rod 18 drives the slide 13 to slide to both sides along the slide 12. The partition 17 supports the hydraulic rod 18. During the sliding process of the slide 13, the tension of the slide 13 is applied through the pressure valve 19.

[0039] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a slide groove three 25 is embedded on the inner side of the slide 13, and a connecting block 28 is slidably connected to the inner surface of the slide groove three 25. The upper end of the connecting block 28 is fixedly connected to the measuring rod 21. The measuring rods 21 are in two groups and are symmetrically distributed on both sides of the steel bar 16. A scale line 29 is provided on the outer surface of the slide 13 at the lower side of the slide groove two 20.

[0040] An air bag 22 is fixedly connected to the inner surface of the box body 11 above the pressure valve 19, and an outer surface of the air bag 22 is fixedly connected to the slide 13. An air pipe 26 is fixedly connected to one end of the air bag 22 close to the slide 13, and the air pipe 26 is embedded in the inner side of the slide 13.

[0041] An airbag 2 24 is provided on the inner side of the slide groove 3 25 , one end of the airbag 24 is fixedly connected to the inner surface of the slide groove 3 25 and the other end is fixedly connected to the connecting block 28 .

[0042] By adopting the above technical solution, during the operation of the stretching component 1, as the slide 13 slides toward the two sides of the box body 11, the airbag 1 22 will be compressed. At this time, the gas in the airbag 1 22 passes through the trachea 1 26 and the trachea 2 27 in turn under the action of pressure and enters the interior of the airbag 2 24. As the airbag 2 24 is inflated, the connecting block 28 is pushed to move toward each other along the slide groove 3 25. The connecting block 28 drives the measuring rod 21 to move synchronously along the slide groove 2 20 until the measuring rod 21 is in contact with the outer surface of the steel bar 16. The diameter of the steel bar 16 is measured by observing the position of the scale line 29 corresponding to the measuring rod 21. At the same time, the diameters of the two ends of the steel bar 16 are measured synchronously. By combining the two sets of data, the diameter of the steel bar 16 can be quickly measured while greatly improving the measurement accuracy.

[0043] like Figure 1 、 Figure 3 and Figure 7 As shown, the lower end of the output shaft of the motor 31 passes through the lower side of the bracket 37 and is fixedly connected to the sleeve 34. The inner surface of the sleeve 34 is spirally connected to the rotating shaft 35. The outer surface of the upper end of the box body 11 is fixedly connected to the support plate 32, and the upper end of the support plate 32 is fixedly connected to the bracket 37.

[0044] The front outer surface of the support plate 32 is fixedly connected to the fixing plate 33 , the rotating shaft 35 passes through the upper and lower ends of the fixing plate 33 and is slidably connected to the fixing plate 33 , and the lower end of the rotating shaft 35 is fixedly connected to the rebound hammer 36 .

[0045] By adopting the above technical solution, when testing the strength of concrete or bricks, the driving component 3 is first operated to make the motor 31 conductive. The output shaft of the motor 31 drives the sleeve 34 to rotate synchronously. The rotating shaft 35 is connected to the sleeve 34 through a spiral transmission and gradually moves downward as the sleeve 34 rotates. The support plate 32 supports the rotating shaft 35 through the fixed plate 33. The rotating shaft 35 drives the rebound tester 36 to quickly test the strength of the concrete, thereby monitoring the quality of the building construction.

[0046] like Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9 As shown, an adjustment component 4 is provided on the outer surface of the upper end of the box body 11, and the adjustment component 4 includes a connecting plate 43 fixedly connected to the outer surface of the upper end of the box body 11, and a screw rod 44 passes through the middle of the connecting plate 43.

The front end of the connecting shaft 47 passes through the outside of the box body 11 and is fixedly connected to a handle 45.

[0048] By adopting the above technical solution, when conducting strength testing on concrete blocks, it is usually necessary to test different positions on the surface of the concrete blocks. At this time, the operator is often required to frequently move with the concrete, which greatly increases the labor intensity of the operator. Therefore, an adjustment mechanism is provided. The user can rotate the handle 1 45, and the handle 1 45 drives the gear 48 to rotate synchronously through the connecting shaft 47. The teeth 49 rotate with the gear 48 through the engagement with the gear 48, driving the slide 1 40 to slide left and right along the surface of the box body 11, and then drive the box body 42 to move through the slide 1 40. At the same time, the user can rotate the handle 2 46, and the handle 2 46 drives the screw rod 44 to rotate synchronously. The screw rod 44 is connected to the connecting plate 43 through the spiral transmission. It pushes the slide 2 41 to move back and forth with the screw rod 44. The slide 2 41 pushes the box body 42 to move longitudinally along the surface of the slide 1 40, thereby realizing accurate adjustment of the position of the box body 42, which greatly reduces the labor intensity of the user.

[0049] Instructions for use: When the testing device is used, firstly, the tensile strength of the steel bar 16 is tested through the stretching component 1. At this time, the splint 14 is threadedly connected to the slide 13 through the bolt 15 to clamp and fix the steel bar 16. The hydraulic rod 18 drives the slide 13 to slide to both sides along the slide 12. During the process of the slide 13 stretching the steel bar 16, the tension of the slide 13 is tested through the pressure valve 19. During the operation of the stretching component 1, the slide 13 will compress the airbag 1 22 during the movement. The gas in the airbag 1 22 enters the inside of the airbag 2 24 through the air pipe 1 26 and the air pipe 2 27, so that the airbag 2 24 is inflated and drives the measuring rod 21 to fit in contact with the outer surface of the steel bar 16. The diameter of the steel bar 16 is measured by observing the position of the scale line 29 corresponding to the measuring rod 21, and the strength of the concrete or brick is measured. During strength testing, the output shaft of the motor 31 drives the sleeve 34 to rotate, and the rotating shaft 35 is connected to the sleeve 34 through a spiral transmission, and gradually moves downward as the sleeve 34 rotates. The rotating shaft 35 drives the rebound tester 36 to quickly test the strength of the concrete. When testing the strength of concrete blocks, it is usually necessary to test different positions on the surface of the concrete blocks. At this time, the handle 45 drives the gear 48 to rotate synchronously through the connecting shaft 47, and the teeth 49 rotate with the gear 48 through the engagement with the gear 48, driving the slide 1 40 to slide horizontally along the surface of the box body 11. The handle 2 46 drives the screw rod 44 to rotate synchronously. The screw rod 44 is connected to the connecting plate 43 through a spiral transmission, and drives the slide 2 41 to move longitudinally as it rotates. The slide 2 41 pushes the box body 42 to move longitudinally along the surface of the slide 1 40, thereby achieving the adjustment of the position of the box body 42.
