[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0019] Please refer to Figures 1-2 The utility model embodiment includes:
[0020] As Figure 1 The gypsum self-leveling mortar setting time testing device shown in the figure, including: insulating container 5, timer 3, ohmmeter 4, positive lead 6, negative lead 7 and base 1, the insulating container 5 is injected with gypsum self-leveling mortar 9, the gypsum self-leveling mortar 9 can be first stirred by the stirrer, then immediately inject into the insulating container 5, the gypsum self-leveling mortar 9 at this time has certain conductivity.
[0021] The gypsum self-leveling mortar setting hardens and no longer conducts electricity, and the setting time test can be carried out by using this principle. In the embodiment, the insulating container 5 adopts insulating glass cup, insulating plastic cup or insulating ceramic cup, which has good insulating effect and avoids adverse effects on the test.
[0022] The gypsum self-leveling mortar 9 is provided with first test point A and second test point B, in the embodiment, the distance between the first test point A and the second test point B is not less than 2cm, avoiding the short circuit problem in the test process. The vertical distance between the first test point A and the second test point B and the bottom surface of the gypsum self-leveling mortar 9 is not less than one third of the height of the gypsum self-leveling mortar, the first test point A and the second test point B are away from the bottom surface of the gypsum self-leveling mortar 9, which ensures the accuracy of the test.
[0023] The insulating container 5 is placed on the base 1, the base 1 is provided with lead support 2 on both sides of the insulating container 5 and corresponding to the positive lead 6 and the negative lead 7, as Figure 2 The positive lead 6 and the negative lead 7 are supported by the lead support 2. In the embodiment, the timer 3 and the ohmmeter 4 are placed on the base 1, which is convenient to carry and compact in structure.
[0024] As Figure 1As shown, the head end of the positive electrode lead 6 is connected to the positive electrode of the ohmmeter 4, the tail end of the positive electrode lead 6 is directly or indirectly electrically connected to the first test point A, the head end of the negative electrode lead 7 is connected to the negative electrode of the ohmmeter 4, and the tail end of the negative electrode lead 7 is directly or indirectly electrically connected to the second test point B. Before the gypsum self-leveling mortar 9 is hardened, the gypsum self-leveling mortar between the first test point A and the second test point B can conduct electricity. The ohmmeter 4 is used to test whether there is current between the first test point A and the second test point B, which can reflect the setting process of the gypsum self-leveling mortar.
[0025] The timer 3 starts timing from the time when the gypsum self-leveling mortar 9 is injected into the insulating container 5, and the timing of the timer 3 ends when the ohmmeter 4 reading is zero. The setting time of the gypsum self-leveling mortar 9 can be obtained through the timer 3.
[0026] In order to improve the operation simplicity, as shown, Figure 1 The lead support 2 includes a column 12, a cantilever 11, an insulating tube 14 and a conductive probe 8. The column 12 is vertically arranged on the base 1 and can be fixed by bolts or welding. The structure is stable.
[0027] The cantilever 11 is arranged on the column 12 in a lifting manner and extends horizontally above the insulating container 5. In this embodiment, a first nut 13 is arranged below the cantilever 11 on the column 12. The first nut 13 cooperates with the external threads on the column 12 to limit the downward movement of the cantilever 11 and adjust the height of the position.

The insulating tube 14 can be injection molded with insulating plastic and wrapped around part of the conductive probe 8, improving the structural stability. In this embodiment, the cantilever 11 is provided with a sliding groove 10 extending along the length thereof and corresponding to the insulating tube 14. The insulating tube 14 vertically penetrates the sliding groove 10, facilitating the lateral adjustment of the insulating tube 14 and changing the distance between the conductive probes 8 on both sides to adapt to the position changes of the first test point A and the second test point B.
[0030] A second nut 15 is arranged on the insulating tube 14 above and below the cantilever 11. The second nut 15 cooperates with the external threads on the insulating tube 14 to fix the insulating tube 14 after adjustment, and the structure is firm. As shown, Figure 1 The top of the conductive probe on the right side is connected to the tail end of the positive electrode lead 6, and the top of the conductive probe on the left side is connected to the tail end of the negative electrode lead 7.Figure 2 The conductive probes on both sides are inserted into the corresponding first test point A and second test point B after moving down with the cantilever 11, the current between the first test point A and the second test point B is detected, the setting process of the gypsum self-leveling mortar is reflected, and the first nut 13 is used for limiting, so that the continuous downward movement of the conductive probe is avoided, and the setting of the gypsum self-leveling mortar is not affected.
