DETAILED DESCRIPTION

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0019] Reference Figs. 1-3An acid and alkali resistant tape includes a tape shaft 2 made of corrosion-resistant plastic. A tape body 1 is wound around the outside of the tape shaft 2. An acid and alkali resistant protective film 6 is provided on the tape body 1. The acid and alkali resistant protective film 6 is a high-temperature resistant polyester film with a fluorinated surface to enhance its chemical corrosion resistance. A tape substrate 7 is provided at the bottom of the acid and alkali resistant protective film 6. An adhesive layer 8 is provided at the bottom of the tape substrate 7. A first insertion hole 4 is provided on one side wall of the tape shaft 2. A second insertion hole 16 is provided at the bottom inside the first insertion hole 4. A pull rod 5 is provided on one side of the tape shaft 2. A plug 3 is fixedly installed at one end of the pull rod 5. A blade 9 is fixedly installed on the side wall of the plug 3 away from the pull rod 5. The plug 3 is adapted to the first insertion hole 4, and the blade 9 is adapted to the second insertion hole 16. An acid and alkali resistant layer is provided on the outside of the blade 9. The acid and alkali resistant layer is a polytetrafluoroethylene (PTFE) coating.

[0020] The first insertion hole 4 is rectangular. Mounting grooves 10 are provided on both inner walls of the first insertion hole 4. Limiting grooves 12 are provided on both outer walls of the insertion block 3. One end of a spring 11 is fixedly connected to the inner wall of the end of the two mounting grooves 10 away from the first insertion hole 4. The other end of the two springs 11 is fixedly connected to a limiting block 13 that slides with the inner wall of the mounting groove 10. Two first magnetic blocks 14 are embedded on the side wall of the insertion block 3 away from the pull rod 5. Two second magnetic blocks 15 are embedded in the bottom of the first insertion hole 4. Both limiting blocks 13 are hemispherical. Both limiting blocks 13 are compatible with the two limiting grooves 12. The first magnetic blocks 14 and the second magnetic blocks 15 have opposite magnetic properties. The opposite magnetic configuration makes the insertion block 3 produce a noticeable attraction when it is inserted into place. The double locking mechanism significantly improves the stability of the blade 9 in the storage state.

[0021] In use, the acid and alkali resistant protective film 6 is made of high-temperature resistant polyester film, which has good toughness, oil resistance, and insulation. The tape substrate 7 is made of synthetic rubber film, which has good acid and alkali resistance, so it can be used in acidic and alkaline environments. When the tape body 1 needs to be cut, because the limiting block 13 is hemispherical, the user can pull out the insert block 3 and the blade 9 through the pull rod 5, thus eliminating the need for additional cutting tools and making it convenient to use. After use, the blade 9 is engaged with the second insertion hole 16, and the insert block 3 is engaged with the first insertion hole 4. After the insert block 3 is inserted into the first insertion hole 4, as shown in the attached... Fig. 3 As shown, by setting a hemispherical limiting block 13 to cooperate with the limiting groove 12 again, and by setting a spring 11, the insert block 3 and the blade 9 can be limited. When there is no external force, the insert block 3 will not move away from the first insertion hole 4. At the same time, by setting the magnetic attraction of the first magnetic block 14 and the second magnetic block 15, it can be further ensured that the blade 9 will not easily fall out when not in use.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
