[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0034] Please refer to Figure 1 , the cement mortar impermeability test device in this embodiment includes a control box main body 1. A workbench 2 is fixed on the upper surface of the control box main body 1. A plurality of chassis 3 are fixed on the upper surface of the workbench 2. A test mold main body 4 is attached to the inner side of the chassis 3. A support plate 5 is fixed on the upper surface of the workbench 2. A fixing mechanism 6 is provided on the support plate 5.

[0035] It should be noted that through the fixing mechanism 6, the fixing of a plurality of test mold main bodies 4 filled with mortar specimens can be conveniently and quickly realized, effectively avoiding errors caused by negligence due to operator fatigue, reducing manual operations, effectively improving the test accuracy and continuity, and improving the test efficiency and accuracy.

[0036] Please refer to Figure 1-6, To improve the testing efficiency and accuracy of the device, the fixing mechanism 6 in this embodiment includes a starting component, a fixing component, and a guiding component. The starting component includes a double-shaft motor 601 fixed to the middle of the inner top wall of the support plate 5, two worm gears 602, two worm wheels 603, two bidirectional screws 604, two groups of moving sliders 605, and two groups of articulated rods 606. A threaded bar is fixed to the outer surface of the worm gear 602. The end of the worm gear 602 away from the double-shaft motor 601 is rotatably connected to the inner side wall of the support plate 5 through a bearing, which increases the stability and reliability of the worm gear 602 during rotation and ensures the stability of the device during long-term operation. The output shaft of the double-shaft motor 601 is fixed to one end of the worm gear 602. The worm gear 602 is engaged with the worm wheel 603. The inner wall of the center of the worm wheel 603 is fixed to the middle of the outer surface of the bidirectional screw 604 whose two ends are rotatably connected to the left and right sides of the inner cavity of the support plate 5 through bearings respectively. Two moving sliders 605 are threadedly connected to the left and right sides of the outer surface of the bidirectional screw 604. The top of the articulated rod 606 is articulated to the bottom of the moving slider 605. By driving the worm wheel 603 and the bidirectional screw 604 to rotate through the double-shaft motor 601, it is convenient to adjust the fixing component subsequently.

[0037] Among them, the fixing component includes an adjusting plate 607 articulated to the bottoms of the four articulated rods 606, a plurality of fixing blocks 608, and a connecting block 609 fixed to the outer surface of the test die body 4. A plurality of communication holes slidably connected to the chassis 3 are formed on the adjusting plate 607. A fixing groove 610 is formed on the upper surface of the connecting block 609. The fixing groove 610 is slidably connected to the connecting block 609. A sealing ring is fixed to the lower surface of the connecting block 609. The sealing ring is attached to the upper surface of the chassis 3. The sealing ring ensures the sealing performance of the device during operation and further prevents the intrusion of moisture and impurities. By driving the fixing block 608 to move and fit with the inner wall of the fixing groove 610 through the adjusting plate 607, the stable fixation of the test die body 4 is realized, which is beneficial to the subsequent detection of the device.

[0038] At the same time, the guiding component includes guiding slide rails 611 fixed to the left and right sides of the inner cavity of the support plate 5. A guiding slider 612 is slidably connected to the inner wall of the guiding slide rail 611. A T-shaped chute adapted to the guiding slider 612 is formed on the inner wall of the guiding slide rail 611. The opposite sides of the two guiding sliders 612 are respectively fixed to the left and right sides of the adjusting plate 607, which facilitates the guiding slider 612 to move along the guiding slide rail 611 during movement, makes the movement of the guiding slider 612 more stable, ensures the accuracy of the movement path of the adjusting plate 607, and improves the overall precision of the device.

[0039] In this embodiment, by using the fixing mechanism 6, the test mold bodies 4 filled with mortar specimens can be fixed efficiently and quickly, thus effectively avoiding errors caused by negligence due to personnel fatigue, reducing the manual operation links, not only improving the accuracy and continuity of the test, but also enhancing the overall test efficiency and precision.

[0040] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0041] The working principle of the above embodiment is as follows:

[0042] When it is necessary to test the mortar specimen to be detected in the test mold body 4, first move the test mold body 4 and the mortar specimen to be detected in the test mold body 4 so that the test mold body 4 fits with the chassis 3. At this time, the sealing ring on the lower surface of the connecting block 609 fits with the upper surface of the chassis 3. Then start the double-shaft motor 601 to drive the worm 602 and the worm gear 603 to rotate, so that the bidirectional screw 604 can be rotated to drive the two moving sliders 605 to move, and the articulated rod 606 and the adjusting plate 607 can be moved. When the adjusting plate 607 moves, the guiding slider 612 moves along the guiding slide rail 611 as the adjusting plate 607 moves, so that the movement of the adjusting plate 607 is more supported and the movement is more stable. The movement of the adjusting plate 607 can drive the fixing block 608 to move, and as the adjusting plate 607 moves, the fixing block 608 moves into the fixing groove 610 and fits with the inner wall of the fixing groove 610. At this time, multiple test mold bodies 4 and multiple chassis 3 can be correspondingly fixed, which is convenient for subsequent impermeability tests on the mortar specimens to be detected, without repeated manual operations, improving the flexibility of the operation, and effectively avoiding incomplete thread connection caused by the negligence of the operator due to fatigue during continuous multiple tests, reducing the possibility of human error affecting the accuracy and repeatability of the test, further realizing the rapid, accurate and continuous impermeability test of the mortar specimens, and effectively improving the test efficiency and accuracy.
