Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a testing device for leak-sealing materials. Background Technology

[0002] Leak-stopping compound is an inorganic waterproof and leak-stopping material. It is a powdered leak-stopping material made of cement as the main component and additives through a certain process. It is used for waterproofing, seepage prevention and leak-stopping. It is divided into two types: quick-setting type and slow-setting type. The quick-setting type is mainly used for leak-stopping on the base layer where there is leakage or water seepage.

[0003] While most existing leak-sealing materials can be placed and assembled in a test cylinder before undergoing a water-sealing capacity test, some leak-sealing material testing devices generally cannot perform multi-point simultaneous water-sealing capacity testing. Furthermore, placing the leak-sealing material requires adjusting multiple fixing components to achieve assembly, resulting in a cumbersome and labor-intensive process, thus reducing the efficiency of leak-sealing material testing. Utility Model Content

Detailed Implementation

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a leak-sealing material testing device, including a test chamber 1. The surface of the test chamber 1 is provided with an external groove 2. An internal rectangular frame 3 is slidably installed on the inner side of the test chamber 1. An external collar 4 is rotatably installed on the surface of the internal rectangular frame 3. The surface of the external collar 4 is provided with a positioning screw groove 5. The external collar 4 is threadedly installed on the inner wall of the external groove 2 on the test chamber 1 through the positioning screw groove 5. By adjusting the external collar 4 with the external groove 2 on the test chamber 1 through the thread, the external collar 4 can drive the internal rectangular frame 3 to adjust up and down on the inner side of the test chamber 1.

[0025] Furthermore, an internal recessed frame 6 is slidably installed on the inner side of the test chamber cylinder 1, and an internal guide rod 7 is slidably installed on the inner side of the internal recessed frame 6. The end of the internal guide rod 7 away from the internal recessed frame 6 is fixedly installed on the inner side of the test chamber cylinder 1. An elastic component 8 is slidably sleeved on the surface of the internal guide rod 7. The two ends of the elastic component 8 are respectively fixedly installed on the surface of the internal recessed frame 6 and the inner side of the test chamber cylinder 1. The surface of the internal rectangular frame 3 abuts against the surface of the internal recessed frame 6. An external through groove 9 is opened on the surface of the test chamber cylinder 1. When the internal rectangular frame 3 no longer forms a squeezing obstruction on the internal recessed frame 6, the internal recessed frame 6 is pushed by the elasticity of the compressed internal guide rod 7 to rise inside the test chamber cylinder 1 until the internal recessed frame 6 reaches the external through groove 9 on the test chamber cylinder 1. Then, the relevant sealing materials inside the internal recessed frame 6 can be replaced or other operations can be performed.

[0026] Furthermore, an internal storage plate 10 is slidably installed on the inner side of the internal recess 6, and a sealing material body 11 is bonded to the inner side of the internal storage plate 10. The surface of the internal storage plate 10 is sloped, and a limiting support rod 12 is slidably installed on the inner side of the internal storage plate 10. The end of the limiting support rod 12 away from the internal storage plate 10 is fixedly installed on the inner side of the internal recess 6. A test base 13 is bonded to the surface of the test chamber cylinder 1. The surface of the test base 13 has test slots 14. There are five sets of test slots 14, and the radii of the five sets of test slots 14 gradually decrease. When it is necessary to test the sealing material, the operator only needs to control the external collar 4 to drive the internal rectangular frame 3 to rise inside the test chamber cylinder 1. At this time, the internal recess 6 is pushed up by the elasticity of the compressed elastic component 8. When the internal recess 6 reaches the external through slot 9 on the test chamber cylinder 1, the operator controls the internal storage plate 10 to slide out inside the internal recess 6. Therefore, the internal storage plate 10 gradually slides to the outside of the test chamber cylinder 1.

[0027] Furthermore, the operator controls the replacement or cleaning of the sealing material 11 at the built-in storage plate 10, then resets the built-in storage plate 10 into the built-in recess 6, and the built-in recess 6 into the test chamber cylinder 1. The operator then controls the external collar 4 to lower the built-in rectangular frame 3 to form a positioning assembly with the test chamber cylinder 1. At this time, the built-in storage plate 10 on the built-in recess 6 can form a smoother docking assembly with the test chamber cylinder 1 due to its slope. Then, by passing water through the built-in rectangular frame 3 and applying pressure, the sealing material 11 on the built-in storage plate 10, under pressure, will interact with the test slots 1 of different radii on the test base 13. 4. Conducting tests on the ability to block water inflow. This method ensures that when different sealing materials 11 are tested for their ability to block water inflow inside the test chamber 1, they have the ability to perform simultaneous operation and multi-effect tests. This improves the efficiency of the sealing material 11 in conducting simultaneous tests on test slots 14 of different radii. Furthermore, the adjustment of the built-in rectangular frame 3 and the built-in recessed frame 6 makes it easy to disassemble and replace the sealing material 11. This improves the cumbersome process of disassembling and separating multiple parts when removing the traditional sealing material 11. As a result, the overall ability of different sealing materials 11 to perform multi-effect tests when testing their ability to block water inflow is improved.

[0028] Working Principle: A leak-sealing material testing device. When a leak-sealing material needs to be tested, the operator only needs to control the external collar 4 to drive the internal rectangular frame 3 to rise inside the test chamber cylinder 1. At this time, the internal recess 6 is pushed upward by the elastic force of the compressed elastic component 8. When the internal recess 6 reaches the external through groove 9 on the test chamber cylinder 1, the operator controls the internal storage plate 10 to slide out inside the internal recess 6. Thus, the internal storage plate 10 gradually slides to the outside of the test chamber cylinder 1. At this time, the operator controls the replacement or cleaning of the sealing material body 11 at the internal storage plate 10. The operation is performed, and then the built-in storage plate 10 is reset to the inside of the built-in recess 6, and the built-in recess 6 is reset to the inside of the test chamber cylinder 1. Then the operator controls the external collar 4 to drive the built-in rectangular frame 3 to descend and form a positioning assembly with the test chamber cylinder 1. At this time, the built-in storage plate 10 on the built-in recess 6 can form a smoother docking assembly with the test chamber cylinder 1 through its own slope. Then, after water is passed through the built-in rectangular frame 3 and pressure is applied, the sealing material body 11 on the built-in storage plate 10 will be subjected to pressure and will conduct a sealing water inflow test with the test slots 14 of different radii on the test base 13.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
