Description

magnetic conduction dart

The present invention relates to the technical field of darts, in particular to a magnetic conduction dart applied to a magnetic induction dart board.

Darts is a common leisure and entertainment game. It shoots darts towards a dart board, makes the dart jab positioned on the dart board, and calculates the score according to the position. With various scoring methods, many ways to play can be derived, and Players who do not know each other can compete 1-on-1, or compete in teams, so it is very popular.

The early dart shooting system used manual scoring methods, such as one-dart scoring or three-dart scoring. It is convenient, so manual recording is time-consuming and error-prone.

In recent years, due to the advancement of electronic technology, in order to improve the shortcomings of manual scoring, many manufacturers have developed the technology of generating magnetic lines of force from the dart body to cooperate with plastic dart needles. The dart needle, which is coated with a conductive layer or a conductive sleeve on the plastic dart needle, but the following problems still occur after this technology is put into practice:

First, the conventional plastic dart needle is plated with a conductive layer or a conductive sleeve. Although this method can reduce the false induction caused by the magnification of magnetic lines of force, the conductive layer and the conductive sleeve on the outside of the plastic dart needle can be used at high speed. After impact and wear, it is very easy to fall off or fall off, and it will cause irreparable damage after falling off (the dart needle loses its magnetic induction function).

Second, the conductive layer or conductive sleeve wrapped around the dart needle will still generate divergent magnetic lines of force larger than the outer diameter of the dart needle (the outer diameter of the conductive layer and the conductive sleeve itself is already larger than the outer diameter of the dart needle). It is still not possible to precisely prevent false inductions from occurring.

Thirdly, the material of the conductive layer or the conductive sleeve is usually hard and expensive, which not only increases the cost of the product, but also accelerates the wear of the soft dart target under long-term use.

In view of this, in order to effectively solve the above-mentioned shortcomings, the creator of the present invention, based on the research and development technology and experience accumulated in the field of darts in the past, after continuous efforts, finally introduced a stable magnetic, long-lasting magnetic conduction effect, and more magnetic induction. Accurate, to ensure the quality of the dart and to score the correct magnetic conduction dart, it has become the idea and research topic of the creator of the present invention.

The purpose of the present invention is to provide a magnetic conduction dart with stable magnetic properties, lasting magnetic conduction effect, and more accurate magnetic induction, so as to ensure the quality of the dart and score the correct magnetic conduction.
