[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1 As shown, a concrete rebound tester for concrete testing includes a rebound tester body 2, an inner cavity of the rebound tester body 2 is installed with a rebound rod 3, the outer surface of the rebound tester body 2 is provided with a threaded groove 4, the top of the threaded groove 4 is threadedly connected with a shockproof sleeve 1, and the provision of the shockproof sleeve 1 can have excellent shock resistance and buffering performance, and can reduce the vibration felt by the human hand, thereby improving the stability during the measurement process, the outer surface of the shockproof sleeve 1 is provided with a cleaning component 5, the inner wall of the shockproof sleeve 1 is provided with a shockproof component 6, and the top outer surface of the shockproof sleeve 1 is fixedly installed with a display 7, and the front and rear sides of the display 7 are provided with LED lights 8. The provision of the LED lights 8 can enable the rebound tester to perform detection in a darker area, can accurately align with the concrete detection surface, make the detection data clear to read, and ensure that the rebound tester can be used normally.
[0024] like Figure 2 、 3 As shown, the cleaning assembly 5 includes a circular frame 51, and the circular frame 51 is slidably connected to the shockproof sleeve 1. Sliders 52 are fixedly installed at the four ends of the inner wall of the circular frame 51, and grooves 57 are provided at the four corners of the outer surface of the shockproof sleeve 1.
[0025] like Figure 2 、 3 As shown, the slider 52 is slidably connected to the groove 57, and the four corners of the left end of the circular frame 1 51 are fixedly installed with connecting rods 53, and the left ends of the connecting rods 53 are commonly installed with the circular frame 2 54.
[0026] As can be seen from the above, by pushing the circular frame 51 by hand, the slider 52 can be pushed to move, and the slider 52 slides in the groove 57 to move the cleaning device.
[0027] like Figure 2 、 3 As shown, electric cylinders 55 are provided on both the front and rear sides of the circular frame 2 54 , and arc-shaped brushes 56 are fixedly connected to the output ends of the two electric cylinders 55 .
[0028] As can be seen from the above, the electric cylinder 55 is started and can push the two curved brushes 56 to move relative to each other. When the two curved brushes 56 are in contact, the inside of the two curved brushes 56 just fits with the outside of the impact rod of the concrete rebound test hammer body 2, so that the impact rod 3 of the concrete rebound test hammer body 2 and the two curved brushes 56 move relative to each other, and the impact rod 3 of the concrete rebound test hammer body 2 can be cleaned without using tools such as rags, saving time in finding tools and improving maintenance efficiency.
[0029] like Figure 4 As shown, the shockproof assembly 6 includes four springs 61, which are fixedly connected to the shockproof sleeve 1. A rubber damping pad 1 62 is fixedly installed inside the four springs 61. A rubber damping pad 2 is provided on the outer surface of the rebound tester body 2. The springs 61 can reduce the vibration and have a buffering effect. Then, an anti-slip pad is fixedly installed on the surface of the shockproof sleeve 1. The anti-slip pad can avoid the deviation of the data caused by slipping of the hand during measurement.
[0030] The working principle of the present invention is as follows: when in use, after the concrete inspection is completed, the circular frame 51 is pushed by hand, and the slider 52 can be pushed to move. The slider 52 slides in the groove 57, and the cleaning equipment can be moved. When it moves to a certain position, the electric cylinder 55 is started, and the two arc-shaped brushes 56 can be pushed to move relative to each other. When the two arc-shaped brushes 56 are in contact, the inside of the two arc-shaped brushes 56 just fits with the outside of the impact rod of the concrete rebound test hammer body 2, so that the impact rod 3 of the concrete rebound test hammer body 2 and the two arc-shaped brushes 56 move relative to each other, and the impact rod 3 of the concrete rebound test hammer body 2 can be cleaned. There is no need to use tools such as rags, which saves time in finding tools and improves maintenance efficiency. The spring 61 can reduce the vibration and has a buffering effect. Then, an anti-slip pad is fixedly installed on the surface of the anti-vibration sleeve 1. The anti-slip pad can avoid the deviation of data caused by hand slipping during measurement.
