Problems solved by technology

[0002] Nuts on the existing market are all tightened by hand tools such as wrenches when tightening, and then disassembled by hand tools; shape, store medicines with health functions inside, and the formulas of these medicines with health functions are kept secret. In order not to leak these formulas, people want to store medicines in their carry-on items. After tightening them with nuts , the nut cannot be disassembled to ensure that the formula of the medicine will not leak out, but the nuts currently on the market can be easily disassembled, which cannot meet people's requirements

Embodiment Construction

[0010] A fool-proof nut, comprising a steel sleeve shell 9, a spring ring 8 is installed in the steel sleeve shell 9, when using the present invention, it is only necessary to tighten the steel sleeve shell 9 of the present invention by rotating, Set on the corresponding threaded interface that needs a nut, the spring ring 8 will be clamped on the thread. The structure of the spring ring 8 can prevent the present invention from being disassembled by ordinary hand tools, and can be disassembled by the special tool corresponding to the present invention. At the same time, the structure of the spring ring 8 in the steel sleeve shell 9 will also be destroyed, so that the present invention becomes an ordinary nut; the bottom of the steel sleeve shell 9 is inlaid with a silicone ring 7, and the sealing performance is better ; The steel sleeve shell 9 and the spring ring 8 are all made of stainless steel, and the quality is better, so as to achieve the purpose of the present invention...

Abstract

The invention discloses a poka-yoke screw cap which comprises a steel sleeve shell, wherein the steel sleeve shell is internally provided with a spring ring; and a silica gel ring is inlaid at the inner bottom of the steel sleeve shell, and the steel sleeve shell and the spring ring are made of stainless steel. The poka-yoke screw cap provided by the invention has the beneficial effects that the poka-yoke screw cap is practical, the production cost is low, and when the screw cap is screwed down, the screw cap can be demounted with a custom-made tool; and the demounted screw cap can not be reused, the use is convenient, and people is prevented from viciously opening the screw cap, thus the use is safe.

Description

technical field [0001] The invention relates to a nut, in particular to a foolproof nut. Background technique [0002] Nuts on the existing market are all tightened by hand tools such as wrenches when tightening, and then disassembled by hand tools; shape, store medicines with health functions inside, and the formulas of these medicines with health functions are kept secret. In order not to leak these formulas, people want to store medicines in their carry-on items. After tightening them with nuts , the screw cap is not detachable to ensure that the formula of the medicine will not leak out, but the screw caps on the market can be easily disassembled and cannot meet these requirements of people. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of fool-proof nut aiming at the deficiencies of the existing technology. [0004] In order to achieve the above object, the measures taken by the present invent...
