The shell of the polyurethane elastic shell 7 is provided with a hollow interlayer 17, and the density detector 1 is sleeved in the polyurethane elastic shell 7. One end of the polyurethane elastic shell 7 is connected to an inflation tube 9, and the inflation tube 9 is connected to the hollow interlayer 17. A pressure gauge 11 is installed on the inflation tube 9 by screws.

[0025] The other end of the polyurethane elastic sleeve 7 is hot-melt connected to the support plate 3 and the top of the support plate 3 is installed with a limiting sleeve 4 by screws. The top of the limiting sleeve 4 is clamped with a card cover 5 and the bottom of the card cover 5 is installed with a detection probe 13 by screws. A self-limiting temperature electric heating tape 14 is provided on the top of the support plate 3 and located in the limiting sleeve 4.

[0026] When in use, the concrete detection equipment can improve the buffering effect of the polyurethane elastic shell 7, play a role in preventing accidental squeezing and impact, and can dry the surface of the detection probe 13 to preserve it for a long time.

[0027] For example, Figure 1 、 2 As shown, the present invention further includes a rubber embedded sleeve 12 at the bottom of the card cover 5 and located on the outer periphery of the detection probe 13, and the detection probe 13 is connected to the density detector 1 through a detection line 6.

[0028] During use, when the card cover 5 is engaged with the top of the limiting sleeve 4, the rubber embedded sleeve 12 enters into the limiting sleeve 4, thereby improving the sealing effect of the connection.

[0029] For example, Figure 1 As shown, the present invention further includes that the detection end of the pressure gauge 11 is located in the inflation tube 9 , and a control valve 10 is provided on the inflation tube 9 and at one end of the pressure gauge 11 .

[0030] During use, the pressure gauge 11 is used to detect the pressure value of the nitrogen gas introduced into the hollow interlayer 17 so that personnel can know the pressure value.

[0031] For example, Figure 1 As shown, the present invention further includes a handle 8 mounted on the top of the polyurethane elastic shell 7 by screws.

[0032] When in use, a worker holds the handle 8 and moves the detection device to the side of the concrete to be detected.

It can also improve the buffering effect of the polyurethane elastic shell 7 and play a role in preventing accidental extrusion and impact.

[0038] The pressure gauge 11 is used to detect the pressure value of the nitrogen gas introduced into the hollow interlayer 17, so that the personnel can know the pressure value. The personnel hold the handle 8 and move the detection device to the side of the concrete to be tested. The detection probe 13 is taken out and placed on the point to be tested.
