[0021] See also Figures 1 to 5The utility model provides a technical solution: a mixture performance testing device, including a device body, the device body includes a fixed seat 1, a support plate 2 is fixedly installed at the bottom of the fixed seat 1, a fixed plate 8 is fixedly installed on the support plate 2, a measuring plate 10 is movably installed between the fixed plates 8, a support seat 3 is movably installed on the top of the fixed seat 1, a movable seat 4 is movably installed on the top of the support seat 3, a cavity 7 is opened inside the movable seat 4, the support seat 3 and the fixed seat 1, a positioning hole 22 and a positioning column 23 are respectively installed on the support seat 3 and the movable seat 4, one end of the positioning column 23 is movably installed inside the positioning hole 22, an observation window 5 is fixedly installed on the fixed seat 1, the support seat 3 and the movable seat 4, and a marking line 6 is fixedly installed on the side of the observation window 5, and the height of the internal concrete is viewed and adjusted by matching the observation window 5 and the marking line 6.

[0022] In this embodiment, a slide groove 9 is provided on the inner wall of the fixed plate 8, and a slider 16 is movably installed inside the slide groove 9. The slider 16 is installed inside the slide groove 9 through a supporting mechanism 18. The slider 16 is connected to the measuring plate 10 through a torsion spring shaft 17. The torsion spring shaft 17 includes an outer tube 19 and an inner rod 20. A torsion spring 21 is fixedly installed between the outer tube 19 and the inner rod 20. A limiting groove 12 is provided on the side of the fixed plate 8. A tension mechanism 13 is fixedly installed inside the limiting groove 12. One end of the tension mechanism 13 is fixed with a limiting groove. The fixed plate 8 is provided with a scale line 11, and the scale line 11 cooperates with the measuring plate 10. A fixing rod 15 is fixed on the limit block. The sides of the support seat 3 and the movable seat 4 are provided with a fixing groove 14. One end of the fixing rod 15 is movably installed in the fixing groove 14. The supporting mechanism 18 and the tension mechanism 13 are both spring structures. The tension mechanism 13 pulls the fixing rod 15 to move downward, and the fixing rod 15 moves downward to achieve limited fixation with the fixing groove 14. The supporting mechanism 18 drives the measuring plate 10 to move downward, and one end of the measuring plate 10 contacts the supporting plate 2 for limited fixation.

[0023] When the device is in use, the height of the entire device is selected according to the height of the concrete measurement required. When the support seat 3 and the movable seat 4 are installed, the positioning column 23 is installed inside the positioning hole 22. The support seat 3, the movable seat 4 and the fixed seat 1 are limited to the left and right through the installation of the positioning column 23 and the positioning hole 22. After the movable seat 4 and the support seat 3 are installed, the fixing rod 15 is moved upward, and the fixing rod 15 slides on the limiting block. After the fixing rod 15 slides, the required space is provided for the installation of the movable seat 4 and the support seat 3. When the fixing rod 15 is installed in the fixing groove 14, the fixing rod 15 is moved to a suitable height through the limiting block. The fixing rod 15 is slidably installed in the fixing groove 14 through the limiting block. After the fixing rod 15 is installed in the fixing groove 14, the tension generated by the tension mechanism 13 generates an extrusion torque between the fixing rod 15 and the fixing groove 14, so that the fixing rod 15 is installed in the fixing groove 14. Inside, the fixing rod 15 provides upper and lower limit fixation for the movable seat 4 or the supporting seat 3. When in use, concrete is added to the inside of the fixing seat 1 through the top of the cavity 7, and the height of the concrete is observed through the observation window 5 and the marking line 6. When the concrete is added, the support plate 2 and the fixing seat 1 are moved upwards through one end of the fixing rod 15 as a handle. The fixing seat 1 loses the supporting force for the concrete, and the concrete collapses freely. The supporting plate 2 is placed on one side of the concrete, and the measuring plate 10 is moved upwards. After the measuring plate 10 moves upwards, it is separated from the supporting plate 2, and the elastic force of the torsion spring 21 makes the measuring plate 10 perpendicular to the fixing plate 8. At the same time, the supporting mechanism 18 drives the measuring plate 10 to drop slightly, and the measuring plate 10 moves up and down in a vertical state with the fixing plate 8. The measuring plate 10 cooperates with the top of the concrete to measure the height after the collapse, thereby completing the measurement and recording of the data, and completing the test of the concrete.
