[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] To address the technical problem in existing technologies where multiple tests require cleaning the self-flowing cup after each test to avoid contamination of gypsum-based mortar affecting test results, thus reducing continuous testing efficiency, this invention provides a gypsum-based self-leveling flowability testing device. When multiple tests are required, simply unlock the previous replacement membrane using a fixing structure, replace it with a new replacement membrane, and lock it in place. This avoids frequent cleaning of the self-flowing cup and improves continuous testing efficiency.

[0040] Please see Figures 1 to 4 , Figures 1 to 4 This is a schematic diagram of the structure of a gypsum-based self-leveling flowability testing device in one embodiment of the present invention. The gypsum-based self-leveling flowability testing device includes a testing platform 1, a testing structure 2, a fixing structure 3, and a membrane-piercing needle 4. The testing structure 2 includes a dial 21, a self-flowing cup 22, and a replacement membrane 23. The dial 21 and the self-flowing cup 22 are disposed on the testing platform 1, with the self-flowing cup 22 spaced above the dial 21. The replacement membrane 23 is laid inside the self-flowing cup 22. The fixing structure 3 is installed on the self-flowing cup 22 and can lock the replacement membrane 23 in the self-flowing cup 22 and can unlock the replacement membrane 23 from the self-flowing cup 22. The membrane-piercing needle 4 is movably disposed on the testing platform 1 and can extend into and detach from the self-flowing cup 22. When it extends into the self-flowing cup 22, it can pierce the replacement membrane 23.

[0041] In the gypsum-based self-leveling flowability testing device provided by this utility model, a replacement membrane 23 is laid inside the self-flowing cup 22, and the replacement membrane 23 is locked onto the self-flowing cup 22 by a fixing structure 3 to prevent the replacement membrane 23 from moving relative to the self-flowing cup 22. Then, gypsum-based mortar is poured into the self-flowing cup 22, and the replacement membrane 23 isolates the gypsum-based mortar from the cup wall of the self-flowing cup 22, preventing the gypsum-based mortar from directly contacting the self-flowing cup 22. During the test, the bottom of the replacement membrane 23 is pierced by a membrane-breaking needle 4, allowing the gypsum-based mortar to flow out from the lower port of the self-flowing cup 22 and fall onto the scale 21, completing the test. Thus, when multiple tests are required, it is only necessary to unlock the previous replacement membrane 23 through the fixing structure 3, replace it with a new replacement membrane 23, and lock it, avoiding frequent cleaning of the self-flowing cup 22 and improving the efficiency of continuous testing.

[0042] It should be noted that the replacement film 23 can be made of the same material as a food storage bag or plastic wrap. In this design, both the replacement film 23 and the self-flowing cup 22 are conical, with openings at the top and bottom of the cup 22. Furthermore, the specific configuration of the fixing structure 3 is not limited, as long as it enables the locking and unlocking of the replacement film 23 on the self-flowing cup 22. In one embodiment, the fixing structure 3 is configured as a fixing bolt, with a screw hole at the upper end of the self-flowing cup 22, and the end edge of the replacement film 23 is pressed into the screw hole by the fixing bolt. In another embodiment, the fixing structure 3 is configured as a pin, with a slot at the end of the self-flowing cup 22, so that the end edge of the replacement film 23 is inserted into the slot by the pin.

[0043] In another embodiment, please refer to Figure 5 The fixing structure 3 includes a fixing cover 31, which is arranged in a ring shape and has a slot 31a. The slot 31a is engaged with the upper edge of the self-flowing cup 22. The edge of the replacement membrane 23 is engaged between the fixing cover 31 and the upper edge of the self-flowing cup 22.

[0044] In this embodiment, the fixing structure 3 is set on the fixing cover 31, and a slot 31a is provided on the fixing cover 31 corresponding to the upper port of the self-flowing cup 22. This allows the edge of the replacement membrane 23 to be locked between the fixing cover 31 and the self-flowing cup 22, ensuring the stability of the replacement membrane 23 when locked. When it is necessary to unlock the replacement membrane 23, it is only necessary to remove the fixing cover 31 from the self-flowing cup 22. The operation is convenient, the structure is simple, and the cost is saved.

[0045] In one embodiment, the fixing structure 3 includes a magnetic suction part 32, which is disposed on the fixing cover 31; the detection structure 2 also includes an adsorption part 24, which is disposed on the self-flowing cup 22 and is magnetically attracted to the magnetic suction part 32.

[0046] In this embodiment, a magnetic structure is provided between the fixed cover 31 and the self-flowing cup 22 to improve the stability of the fixed cover 31 when installed on the self-flowing cup 22, and further improve the stability when the replacement membrane 23 is locked. It should be noted that the specific arrangement of the magnetic suction part 32 and the adsorption part 24 is not limited, as long as magnetic adsorption between the fixed cover 31 and the self-flowing cup 22 can be achieved. In one embodiment, the magnetic suction part 32 and the adsorption part 24 are set as magnets with two different magnetic poles; while in another embodiment, one of the magnetic suction part 32 and the adsorption part 24 is set as a magnet, and the other is set as a base made of iron, cobalt, or nickel.

[0047] In another embodiment, the fixing cover 31 is a flexible fixing cover, the magnetic suction part 32 is a magnetic ring 321, the magnetic ring 321 is covered at the bottom of the slot 31a, the self-flowing cup 22 is a steel self-flowing cup, and its upper edge forms an adsorption part 24.

[0048] In this embodiment, the fixing cover 31 is made of a flexible material such as rubber or silicone, so that the fixing cover 31 can be snapped onto the upper end of the self-flowing cup 22. At the same time, the magnetic suction part 32 is set as a magnetic ring 321 covering the fixing cover 31, and the self-flowing cup 22 is made of steel. This improves the ease of installation and removal of the fixing cover 31, and also ensures the connection stability between the fixing cover 31 and the self-flowing cup 22 through the magnetic ring 321.

[0049] In one embodiment, please refer to Figure 5 and Figure 6 The upper edge of the self-flowing cup 22 is provided with a locking hole 22a. The fixing structure 3 includes a locking pin 33, which is located on the bottom wall of the slot 31a. The locking pin 33 can press the replacement membrane 23 into the locking hole 22a.

[0050] In this embodiment, a locking pin 33 is also provided at the bottom of the slot 31a of the fixed cover 31, and a corresponding locking hole 22a is provided at the upper end of the self-flowing cup 22, so that the replacement membrane 23 can be pressed into the locking hole 22a through the locking pin 33, thereby improving the stability of the replacement membrane 23 when locked.

[0051] In one embodiment, multiple locking pins 33 are provided, and the multiple locking pins 33 are arranged at intervals along the circumference of the fixed cover 31. Multiple locking holes 22a are provided corresponding to the locking pins 33, and the multiple locking pins 33 are respectively inserted into the multiple locking holes 22a.

[0052] In this embodiment, by correspondingly providing multiple locking pins 33 and multiple locking holes 22a, the stability of locking the replacement membrane 23 is further improved, preventing the replacement membrane from moving relative to the self-flowing cup 22 under the gravity of the gypsum-based mortar. It should be noted that in the example in the attached drawings, there are four locking pins 33 and four locking holes 22a.

[0053] In one embodiment, the testing station 1 includes a station body 11 and a support frame 12, with the support frame 12 mounted on the station body 11; a dial 21 is mounted on the station body 11 and located at the bottom of the support frame 12; a free-flowing cup 22 is mounted on the upper end of the support frame 12; and a membrane-breaking needle 4 is movably mounted on the support frame 12 and located above the free-flowing cup 22.

[0054] In this embodiment, the membrane-breaking needle 4 is placed above the free-flowing cup 22 so that the membrane-breaking needle 4 can be inserted into the free-flowing cup 22 and accurately pierce the bottom of the replacement membrane 23, thereby improving the testing efficiency.

[0055] In one embodiment, please refer to Figure 7 and Figure 8 The support frame 12 includes a movable frame 121 and a fixed frame 122. The movable frame 121 is installed on the platform 11 and can move relative to the platform 11. The fixed frame 122 is fixed to the platform 11 and has a mounting arm 123 suspended above the movable frame 121. The self-flowing cup 22 is installed on the movable frame 121. The membrane-breaking needle 4 is installed on the mounting arm 123 and can move relative to the mounting arm 123 in the direction of approaching and moving away from the self-flowing cup 22. The gypsum-based self-leveling flowability detection device also includes a compression spring 5. The compression spring 5 connects the membrane-breaking needle 4 and the mounting arm 123 and is used to drive the membrane-breaking needle 4 from the position of extending into the self-flowing cup 22 to the position of disengaging from the self-flowing cup 22.

[0056] In this embodiment, the tester presses the membrane-breaking needle 4, inserts it into the self-flowing cup 22, and punctures the replacement membrane 23. After the replacement membrane 23 is punctured, the membrane-breaking needle 4 is released. The membrane-breaking needle 4 automatically detaches from the self-flowing cup 22 under the reset of the compression spring 5, improving the convenience of testing.

[0057] In one embodiment, the support frame 12 further includes a guide cylinder 124 and a cleaning brush. The guide cylinder 124 is mounted on the mounting arm 123 and extends in a direction close to the self-flowing cup 22. The cleaning brush is located inside the guide cylinder 124. The membrane breaking needle 4 is located inside the guide cylinder 124.

[0058] In this embodiment, the rupture needle 4 is inserted into the guide tube 124, which guides the rupture needle 4 and prevents it from deviating and contaminating the inner wall of the gravity flow cup 22. Simultaneously, a cleaning brush is provided inside the guide tube 124, allowing the brush to clean the surface of the rupture needle 4 during its upward repositioning process. This prevents the rupture needle 4 from re-entering the gravity flow cup 22 and contaminating the gypsum-based mortar, thus improving test accuracy.

[0059] In one embodiment, the platform 11 is provided with a plurality of slots 11a, and the dial 21 is located in the slots 11a; the movable frame 121 includes a support ring 126 and a plurality of support arms 125, the plurality of support arms 125 are respectively connected to the support ring 126 and inserted into the plurality of slots 11a, and are arranged at intervals along the circumference of the support ring 126, and the self-flowing cup 22 is placed in the support ring 126.

[0060] In this embodiment, multiple support arms 125 are inserted into multiple slots 11a and surround the dial 21 to limit its movement, preventing it from shifting and improving testing accuracy. The movable frame 121 and the platform 11 are detachable for easy transport and storage. It should be noted that a replaceable film can also be laid on the dial 21.

[0061] To better understand this utility model, the following is combined with... Figures 1 to 8 The technical solution of this utility model is described in detail below:

[0062] In this design, a replacement membrane 23 is laid inside the self-flowing cup 22, and the edge of the replacement membrane 23 is secured between the fixed cover 31 and the self-flowing cup 22 to prevent the replacement membrane 23 from moving relative to the self-flowing cup 22. Then, gypsum-based mortar is poured into the self-flowing cup 22. The replacement membrane 23 isolates the gypsum-based mortar from the cup wall of the self-flowing cup 22, preventing direct contact between the gypsum-based mortar and the cup. During testing, the membrane-breaking needle 4 is pressed down, causing it to pierce the bottom of the replacement membrane 23. Releasing the needle allows it to return to its original position under the pressure of the compression spring 5, detaching from the self-flowing cup 22. During this return process, the needle is cleaned by a cleaning brush for reuse. Simultaneously with the piercing of the replacement membrane 23, the gypsum-based mortar flows out from the lower end of the self-flowing cup 22 and falls onto the dial 21, completing the test. Thus, when multiple tests are required, simply unlock the previous replacement membrane 23 by fixing the cover 31, replace it with a new replacement membrane 23 and lock it, avoiding frequent cleaning of the self-flowing cup 22 and improving the efficiency of continuous testing.

[0063] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
