DETAILED DESCRIPTION

[0029] The utility model will be further explained in detail below in combination with the drawings.

[0030] As shown in Figure 1 , Figure 2 , a concrete permeability tester comprises a workbench 1, a mold base 2, a test mold 3, a mounting ring 4, a mounting rod 5, a pressing plate 6 and a locking mechanism 7.

[0031] As shown in Figure 1 , Figure 2 , the workbench 1 is horizontally arranged on the ground, and the mold base 2 is disc-shaped and arranged in two rows on the workbench 1. The test mold 3 is vertically arranged on the mold base 2 in a cylindrical shape, and the upper end of the test mold 3 is provided with a pair of handles 31 for facilitating the disassembly and assembly of the test mold 3.

[0032] As shown in Figure 2 , Figure 3 , the upper end surface of the mold base 2 is provided with a sealing ring 21, and the lower end surface of the test mold 3 is provided with a sealing groove 32 for embedding the sealing ring 21, and a rubber pad 33 is embedded in the sealing groove 32 for increasing the sealing property between the mold base 2 and the test mold 3 and improving the test accuracy.

[0033] As shown in Figure 2 , Figure 3 , the mounting ring 4 is arranged at the lower end outer wall of the test mold 3, and the mounting rod 5 is vertically arranged at the outer edge position of the mold base 2, and the mounting ring 4 is provided with an arc-shaped mounting hole 41 for slidingly embedding the mounting rod 5.

[0034] As shown in Figure 2 , Figure 3 , the pressing plate 6 is arranged at the upper end of the mounting rod 5 and used for pressing the upper end surface of the mounting ring 4, and the side of the pressing plate 6 facing the mounting hole 41 is arranged in an inclined surface, and the end position of the mounting hole 41 is provided with a round hole 42 for passing the pressing plate 6.

[0035] As shown in Figure 2 , Figure 4As shown, the locking mechanism 7 is disposed on the workbench 1 and is used to fix the mounting ring 4. The locking mechanism 7 includes a locking rod 71, a screw 72, a gear 73 and a rack 74.

[0036] like Figure 4 As shown, the locking rod 71 is horizontally slidably connected to the worktable 1, and the screw 72 is threadedly connected to the worktable 1 and rotatably connected to the locking rod 71. The gear 73 is disposed on the outer wall of the mounting ring 4, and the rack 74 is disposed on the side wall of the locking rod 71 and meshes with the gear 73.

[0037] When it is necessary to install the test mold 3, place the test mold 3 on the mold base 2, and make the mounting rod 5 and the pressure plate 6 vertically pass through the round hole 42 on the mounting ring 4. At the same time, the gear 73 on the outer wall of the mounting ring 4 meshes with the rack 74. Then, control the screw 72 to rotate. The screw 72 drives the locking rod 71 and the rack 74 to slide horizontally. Under the cooperation of the gear 73 and the rack 74, control the rotation of the mounting ring 4 and the test mold 3.

[0038] At this point, the locking rod 71 slides within the locking hole, and the pressure plate 6 gradually presses against the upper surface of the mounting ring 4, thus securing the test mold 3 and completing its installation. The disassembly process of the test mold 3 is the reverse, and therefore will not be described in detail.

[0039] Therefore, by setting a rotating snap-fit ​​fixing method, the test mold 3 can be quickly installed and disassembled, making the testing process more convenient and improving testing efficiency. At the same time, by setting a locking mechanism 7 that can control the synchronous locking and unlocking of the entire row of test molds 3, the entire row of test molds 3 can be quickly fixed and disassembled, improving testing efficiency.

[0040] like Figure 3 As shown, a recording card 8 is provided on the upper outer wall of the mold 3. The recording card 8 includes a mounting box 81 and a cardboard 82. The mounting box 81 is transparent and has an opening at the top. The cardboard 82 is placed inside the mounting box 81. Therefore, by setting a recording card 8 on the mold 3 to record data, data can be recorded in a timely manner, making the experimental process more convenient.
