Specific embodiment 1

[0029] In order to solve the problems in the prior art of being inconvenient to carry and shield the concrete strength tester, and being inconvenient to fix and prevent the concrete strength tester body 5 from falling off, this embodiment adopts the following technical solutions, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 First, the rear box cover 3 connected to the damping inside the rear end of the box body 1 can be rotated to disconnect the closed connection between the rear box cover 3 and the box body 1. Then the box body 1 can be laid flat so that the handrail 2 fixed on the box body 1 is parallel to the ground. Then the concrete strength tester body 5 can be placed in the middle of the screw-fixed mounting plate 4 in the box body 1 so that the concrete strength tester body 5 is located on the inner side of the symmetrically arranged clamping plates 6 in the mounting plate 4. Then the worm 9 arranged on the right side of the mounting plate 4 can be rotated so that the worm 9 rotates under the engagement limit of the fixed block 10 arranged outside it. An adjusting rod 7 threadedly connected to the clamping plate 6 is passed through the clamping plate 6. The adjusting rod 7 is non-detachably connected to the mounting plate 4 in a snap-fitting manner. A worm gear 8 is fixedly connected to the right side of the adjusting rod 7. The worm gear 8 is externally meshed with a worm 9. Therefore, by rotating the worm 9, the worm gear 8 drives the adjusting rod 7 to rotate under the snap-fitting limit of the mounting plate 4, so that the adjusting rod 7 drives the clamping plate 6 to move in the mounting plate 4 until the clamping plate 6 is tightly fitted to the outside of the concrete strength tester body 5, thereby achieving the purpose of fixing and preventing the concrete strength tester body 5 from falling off.

[0030] Then the rear box cover 3 can be rotated again to make it fit and connect with the box body 1, so that the concrete strength tester can be shielded and protected by the box body 1, the rear box cover 3, the symmetrically fixed filter screen 13 on the inner side of the outer upper end of the box body 1, and the damping rotation connection side box cover 14 on the inner side of the outer lower end of the box body 1. The concrete strength tester can be carried to the position to be used through the handrail 2 fixed to the box body 1, and then the rear box cover 3 and the worm 9 can be rotated in sequence to disconnect the fixation of the concrete strength tester body 5, take it out, and test the concrete strength. Specific embodiment 2

[0032] In order to solve the problem in the prior art that it is inconvenient to blow and clean the concrete strength tester body 5, this embodiment adopts the following technical solutions, such as Figure 1 and Figure 2 After the concrete strength tester body 5 is used up, it can be restored to its original position, and the side box cover 14 connected to the damping on the inner side of the outer lower end of the box body 1 can be rotated outward to disconnect the fitting connection between the side box cover 14 and the box body 1, and then the rear box cover 3 can be rotated to close the connection with the box body 1. Then, the controller 11 embedded in the inner side of the rear upper end of the box body 1 can be used to control the exhaust fan 12 symmetrically installed on the inner side of the outer upper end of the box body 1 to operate. Since the exhaust fan 12 is tilted toward the concrete strength tester body 5, a filter 13 fixedly connected to the box body 1 is provided on the outer side of the exhaust fan 12. Therefore, through the operation of the exhaust fan 12, the outside air is filtered through the filter 13, drawn into the box body 1 and then blown toward the concrete strength tester body 5, and discharged from the inner side of the outer lower end of the box body 1, so as to achieve the purpose of blowing and cleaning the concrete strength tester body 5. The above electrical components are all prior art and will not be described in detail here.
