Description

Technical Field

[0001] The utility model relates to the field of bonding strength testing equipment, in particular to a finishing layer bonding strength testing instrument. Background Art

[0002] A finishing bond strength tester is a device used to assess the bond strength between a building material surface or coating and its substrate. This instrument is commonly used to test the adhesion of wall coatings, tiles, stone, and other materials to ensure their durability and safety during use. The tester measures the bond strength by applying a certain amount of force to determine whether the material meets relevant standards or specifications.

[0003] Chinese patent application number CN211122483U discloses a bond strength tester comprising a base and two sets of legs. The tops of the two sets of legs are hinged to the base, and the legs are provided with a plurality of positioning holes arranged equiangularly around the hinge point between the legs and the base. The base is slidably connected to a positioning member that engages with the positioning holes. When engaged, the positioning member restricts the rotation of the legs. By employing this technical solution, the two sets of legs can be moved away from each other, increasing the spacing between them. Furthermore, when performing pullout tests on larger tiles, the rotation angle of the two sets of legs can be adjusted so that the ends of the legs away from the base do not contact the tiles, allowing for tile extraction. The positioning member secures and supports the legs, thereby improving the bond strength tester's adaptability to tiles of varying sizes and expanding its use. Furthermore, when the bond strength tester needs to be stored, the two sets of legs can be restored, reducing space requirements.

[0004] However, this device still has some shortcomings: when using this device, it is not convenient to install and disassemble the standard parts, which may cause the disassembly and assembly process to be cumbersome and increase the operation time. Utility Model Content

[0042] Example 2

[0043] The present invention proposes a surface layer bonding strength tester. Compared with the first embodiment, this embodiment describes the structure of the easily disassembled component in detail.

[0044] like Figure 3 As shown, the positioning mechanism includes a second threaded column 16, a second guide column 18 and a positioning plate 19; the second threaded column 16 is rotatably set on the mounting portion 7, and the outer circumference of the second threaded column 16 is symmetrically provided with two groups of threads with opposite rotation directions; the second guide column 18 is set in the mounting portion 7; one end of the positioning plate 19 is threadedly connected to the second threaded column 16, and the other end is slidingly connected to the second guide column 18, and the positioning plate 19 is clamped with the plug column 20; the transmission mechanism includes a worm 15 and a worm wheel 17; the worm 15 is rotatably set on the mounting portion 7, and a rotating block 14 is provided on the top of the worm 15, and the rotating block 14 is located above the mounting portion 7; the worm wheel 17 is set on the second threaded column 16 and engages with the worm 15, and the disassembly assembly can quickly replace the standard part 8, reduce preparation time, and improve test efficiency.
