[0001] This utility model relates to the field of mortar impermeability testing technology, and in particular to a mortar impermeability testing device. Background Technology

[0002] Durability is one of the two basic properties of mortar, while mortar impermeability is the ability of mortar to resist the penetration of various harmful media into the interior of cement mortar. Therefore, the quality of cement mortar impermeability directly affects its durability. Thus, improving impermeability is an effective way to improve the durability of cement mortar. Due to the importance of mortar impermeability to civil engineering and its close relationship with durability, research on mortar impermeability has attracted increasing attention. A mortar impermeability testing device is a device specifically designed to test the impermeability of mortar. It simulates the seepage pressure in the actual environment to test the impermeability of mortar samples in order to evaluate the durability and waterproof performance of the mortar.

[0003] Existing mortar impermeability testing devices typically consist of the following main components: a test mold, a water pump, a pressure control system, and a data acquisition system. This device applies pressure to the mortar test block by simulating a water pressure environment to test its ability to resist water penetration.

[0004] However, the installation of this mortar permeability testing device requires the use of tools such as pry bars to firmly fix the mold to the test table, which is very inconvenient. During installation, operators need to expend considerable effort and time to ensure the mold is securely placed on the test table, undoubtedly increasing their workload and difficulty. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mortar impermeability testing device, which aims to improve the problem that traditional mortar impermeability testing devices require a lot of effort and time to install and disassemble the test mold.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mortar impermeability testing device, comprising a housing, an adjusting valve rotatably connected to the outer wall of the housing, a quick-release assembly provided on the outer wall of the housing, and a demolding assembly provided inside the housing; The quick-release assembly includes a base, a first limiting block fixedly connected to the outer wall of the base, a second limiting block fixedly connected to the outer wall of the base, a first spring provided on the outer wall of the base, an unlocking block slidably connected to the outer wall of the base, a fixing ball groove provided on the outer wall of the base, a fixing ball rotatably connected inside the fixing ball groove, a mold slidably connected to the inner wall of the base, and a groove provided on the outer wall of the mold.

[0007] Furthermore, the demolding assembly includes a demolding button, one end of which is slidably connected to a trapezoidal block. A slide rail is provided on the upper surface of the trapezoidal block, and a slider is slidably connected to the inner wall of the slide rail. A top post is fixedly connected to the outer wall of the slider, and a spring seat is fixedly connected to the outer wall of the top post. A second spring is provided on the upper surface of the spring seat.

[0008] Furthermore, one end of the first spring is fixedly connected to the outer wall of the first limiting block, and the other end of the first spring is fixedly connected to the inner wall of the unlocking block.

[0009] Furthermore, the upper surface of the outer shell is provided with holes.

[0010] Furthermore, one end of the second spring is fixed to the outer wall of the spring seat, and the other end of the second spring is fixedly connected to the inner wall of the outer casing.

[0011] Furthermore, the outer wall of the demolding button is slidably connected to the inner wall of the outer shell, and the outer wall of the trapezoidal block is slidably connected to the inner wall of the outer shell.

[0012] Furthermore, the outer wall of the spring seat is slidably connected to the inner wall of the hole, and the outer wall of the top column is slidably connected to the inner wall of the hole.

[0013] Furthermore, one end of the base is fixedly connected to the outer wall of the outer casing, and the outer wall of the outer casing is provided with a buckle.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a modular installation and disassembly assembly is constructed by two parts: a fixed ball and an unlocking block.

This modular installation and disassembly assembly simplifies the installation and disassembly process and improves the convenience of operation.

[0015] 2. In this utility model, by setting the demolding component, when demolding is required, pressing the demolding button will cause the trapezoidal block to move. The movement of the trapezoidal block will cause the slider to slide within the slide rail. The sliding of the trapezoidal block will cause the top column to move. The movement of the top column will compress the second spring, and the second spring will contract to generate elastic force. At the same time, the top column will push the formed test block out, achieving the effect of easy demolding, avoiding damage to the test block caused by manual knocking during demolding, and improving the integrity of the test block.

The first limiting block 5 and the second limiting block 19 are used to limit the displacement of the unlocking block 7. A first spring 6 is provided on the outer wall of the base 4, and the unlocking block 7 is slidably connected to the outer wall of the base 4. The first spring 6 is used to reset the unlocking block 7. A fixing ball groove 11 is opened on the outer wall of the base 4, and a fixing ball 10 is rotatably connected inside the fixing ball groove 11. A mold 8 is slidably connected to the inner wall of the base 4. A groove 9 is opened on the outer wall of the mold 8, and the fixing ball 10 is used to be inserted into the groove 9 to fix the mold 8.

[0020] Specifically, the mortar test block is placed in the mold 8, and then the unlocking block 7 is slid down to place the mold 8 into the base 4. The unlocking block 7 is lifted by the internal first spring 6, causing the fixing ball 10 to roll into the groove 9 to fix the mold 8, thus achieving quick installation. After recording, the unlocking block 7 is slid down to disengage the fixing ball 10 from the preset groove 9, thereby releasing the fixation of the mold 8 and achieving quick disassembly. This modular installation and disassembly component simplifies the installation and disassembly process and improves the convenience of operation.

[0021] Reference Figure 1 - Figure 5 The demolding assembly includes a demolding button 2, one end of which is slidably connected to a trapezoidal block 17. A slide rail 16 is provided on the upper surface of the trapezoidal block 17, and a slider 15 is slidably connected to the inner wall of the slide rail 16. The slide rail 16 is used to convert the oblique upward movement of the slider 15 into vertical movement. A top post 12 is fixedly connected to the outer wall of the slider 15, and the top post 12 is used to demold the mold 8. A spring seat 14 is fixedly connected to the outer wall of the top post 12, and a second spring 13 is provided on the upper surface of the spring seat 14. The second spring 13 is used to reset the top post 12. One end of a first spring 6 is fixedly connected to the outer side of the first limiting block 5. The outer wall, the other end of the first spring 6 is fixedly connected to the inner wall of the unlocking block 7, the upper surface of the outer shell 1 is provided with a hole 18, one end of the second spring 13 is fixed to the outer wall of the spring seat 14, the other end of the second spring 13 is fixedly connected to the inner wall of the outer shell 1, the outer wall of the demolding button 2 is slidably connected to the inner wall of the outer shell 1, the outer wall of the trapezoidal block 17 is slidably connected to the inner wall of the outer shell 1, the outer wall of the spring seat 14 is slidably connected to the inner wall of the hole 18, the outer wall of the top pillar 12 is slidably connected to the inner wall of the hole 18, one end of the base 4 is fixedly connected to the outer wall of the outer shell 1, and the outer wall of the outer shell 1 is provided with a buckle 20, which is used to fix the mold 8.

[0022] Specifically, by pressing the demolding button 2, the demolding button 2 drives the trapezoidal block 17 to move. The movement of the trapezoidal block 17 causes the slider 15 to slide within the slide rail 16. The sliding of the trapezoidal block 17 causes the top post 12 to move. The movement of the top post 12 compresses the second spring 13. The second spring 13 contracts to generate elastic force. At the same time, the top post 12 ejects the formed test block. After the test block is ejected, the second spring 13 rebounds and causes the top post 12 to reset, thereby achieving rapid demolding of the mold 8.

[0023] Working principle: First, the mixed mortar is poured into mold 8, and then placed in a drying machine to dry. After drying, mold 8 is removed and installed inside clip 20. Then, the demolding button 2 is pressed. Demolding button 2 moves trapezoidal block 17, which in turn moves slider 15 within slide rail 16. The sliding of trapezoidal block 17 moves top column 12, which in turn compresses second spring 13. Second spring 13 contracts to generate elastic force, and at the same time, top column 12 ejects the formed test block. After demolding, the mortar test block is polished and waxed, and then placed in... In mold 8, slide the unlocking block 7 down to place mold 8 into base 4. Then, the first spring 6 inside will lift the unlocking block 7, causing the fixing ball 10 to roll into the groove 9 to fix mold 8. Then, start the water pump to apply pressure to the test block. As the pressure gradually increases, observe whether the test block shows water seepage. When the test block shows water seepage, record the pressure value at this time. This pressure value is the anti-seepage pressure of the mortar. After recording, slide the unlocking block 7 down to make the fixing ball 10 disengage from the preset groove 9. Then, take out mold 8 and install mold 8 inside buckle 20. Perform demolding operation again.
