[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] First embodiment:

[0025] Referring to Figures 1-3, this utility model provides a concrete test block hardness testing device, including a base box 1, a receiving cylinder 102 on the surface of the base box 1, and a movable drawer 101 inside the base box 1, the drawer 101 being correspondingly arranged with the receiving cylinder 102. A sliding plate 6 is slidably connected to the base box 1, the sliding plate 6 being located between the receiving cylinder 102 and the drawer 101; a support frame 2 is connected to the top surface of the base box 1, the support frame 2 is equipped with an electric telescopic cylinder 3 corresponding to the receiving cylinder 102, a pressure testing head 4 is provided on the side wall of the support frame 2, and a connector 301 detachably connected to the pressure testing head 4 is provided on the electric telescopic cylinder 3. When using the device, the concrete test sample is placed inside the receiving cylinder 102, and the sliding plate 6 is used to... The concrete test sample is supported, and the pressure testing head 4 is aligned with the concrete test sample, causing it to extend. The bottom end of the electric telescopic cylinder 3 is connected to the upper end of the pressure testing head 4. As the electric telescopic cylinder 3 extends, the pressure testing head 4 moves downward, allowing pressure to be applied to the concrete test sample. After pressure, cracks or collapses will appear in the concrete test sample. The depth change of the concrete test sample is measured, and the corresponding value is detected by the pressure sensor inside the pressure testing head 4, thereby determining the hardness of the concrete test sample. After use, the sliding plate 6 can be slid out, and the concrete sample will fall into the receiving cylinder 102 for storage.

[0026] Preferably, the sliding plate 6 is made of rubber, which makes it easier to clean and set. Both ends of the sliding plate 6 slide in conjunction with the bottom box 1, which can provide good support for the concrete sample. In a preferred embodiment, a metal frame is provided inside the sliding plate 6 to improve the support effect of the sliding plate 6.

[0027] The second embodiment differs from the first embodiment in that:

[0028] The sliding frame 701 is U-shaped. The open end of the upright plate 7 is slidably connected to the upright plate 7. The sealed end of the sliding frame 701 is provided with a support bolt 8 that is threadedly connected to the upright plate 7. In use, rotating the support bolt 8 can adjust the distance between the sliding frame 701 and the upright plate 7 by means of the threaded connection. Furthermore, scale markings are provided on the outside of the sliding frame 701 to facilitate observation of distance changes. The telescopic end of the electric telescopic cylinder 3 is provided with a beam sensor 901. The support frame 2 is provided with an upright plate 7 corresponding to the electric telescopic cylinder 3. The bottom of the upright plate 7 is connected to the sliding frame 701. Each of the 01 components is connected to an upper photoelectric gate 9 and a lower photoelectric gate 902 corresponding to the beam sensor 901. By changing the distance between the sliding frame 701 and the upright plate 7, the distance between the upper photoelectric gate 9 and the lower photoelectric gate 902 can be changed. When the electric telescopic cylinder 3 extends, the beam sensor 901 passes through the upper photoelectric gate 9 and the lower photoelectric gate 902 in sequence, which can determine the descent distance of the electric telescopic rod 3. When the beam sensor 901 corresponds to the lower photoelectric gate 902, it indicates that the pressure detection head 4 has reached the preset height. The hardness of the concrete sample is detected by the pressure detection of the pressure detection head 4.

[0029] In a preferred embodiment, the device also includes a controller. The electric telescopic cylinder 3, pressure detection head 4, beam sensor 901, lower photoelectric gate 902, and upper photoelectric gate 9 are all electrically connected to the controller. The controller controls the electrical components on the device, thereby improving the ease of operation.

[0030] Furthermore, the support frame 2 is in an inverted "L" shape, and the upright plate 7 and the electric telescopic cylinder 3 are both installed on the inner top surface of the support frame 2.

[0031] The third embodiment differs from the first embodiment in that:

[0032] The support frame 2 has a rotating disk 5 rotatably connected to its side wall. Multiple pressure testing heads 4 are detachable on the rotating disk 5. By rotating the disk 5, different pressure testing heads 4 can be set to correspond with the concrete test samples. When the pressure testing heads 4 are of the same model, there is no need to spend time cleaning the pressure testing heads 4 after the soil test is completed. The pressure testing heads 4 can be replaced directly by rotating the rotating disk 5. During this period, the pressure testing heads 4 can be disassembled for cleaning.

[0033] Furthermore, a magnetic ring is provided on the outer side of the pressure detection head 4, and the rotating disk 5 is made of iron. The magnetic ring is located below the rotating disk 5 and is magnetically attracted to it. Magnetic attraction is used to achieve the magnetic attraction between the magnetic ring and the rotating disk 5. Additionally, a magnetic block is provided on the top surface of the pressure detection head 4, and the connector 301 is made of iron. The inner wall of the connector 301 has a slot corresponding to the high-end magnetic block of the pressure detection head 4. During use, as the electric telescopic cylinder 3 extends, the bottom connector 301 of the electric telescopic cylinder 3 engages with the high-end magnetic block of the pressure detection head 4, and the inner wall of the connector 301 contacts the high-end magnetic block of the pressure detection head 4. The magnetic ring is fixed by adsorption. As the electric telescopic rod 3 continues to extend, the magnetic ring disengages from the rotating disk 5, allowing for pressure testing of the concrete test sample inside the container 102. After pressure is applied, the electric telescopic rod 3 shortens, and the magnetic ring on the outside of the pressure testing head 4 magnetically adsorbs onto the rotating disk 5. As the electric telescopic rod 3 continues to shorten, the inner wall of the connector 301 disengages from the high end of the pressure testing head 4. After the device is used, it can both fix the pressure testing head 4 to the rotating disk 5 and release the separation between the connector 301 and the pressure testing head 4, greatly improving the convenience of installing and disassembling the pressure testing head 4.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
