Abstract

【課題】ナットを専用工具で締める際の掛動力が強力に伝達せず、またナットから専用工具が外れる事により生じる凸部の破損が頻発することにより、この改良が切実に要望されていることを課題とする。
【解決手段】従来ナット頭部の凹部２を多少深く削り、凹部２に対応する凸部４を持つ専用工具底面６がナット上面５において密着することにより、摩擦を生じさせて外れ防止をしたナットである。
【選択図】図２[PROBLEMS] This improvement is urgently demanded because the applied power when a nut is tightened by a special tool is not transmitted strongly, and the convex part frequently breaks when the special tool comes off from the nut. As an issue.
Conventionally, a concave portion 2 of a conventional nut head is shaved somewhat deeply, and a dedicated tool bottom surface 6 having a convex portion 4 corresponding to the concave portion 2 is brought into close contact with a nut upper surface 5, thereby causing friction to prevent the nut from coming off. It is.

Description

ナットを専用工具で締め緩めする際の勘合部密着改良に関するものである。The present invention relates to improvement in fitting of a fitting portion when a nut is tightened and loosened with a special tool.

従来ナット凹部２は浅いために、これから専用工具３が外れやすい状態にある。Since the conventional nut recess 2 is shallow, the special tool 3 is in a state where it is easy to come off.

本考案はナット１を専用工具３で締める際の掛動力が強力に伝達せず、またナット１から専用工具３が外れる事により生じる凸部４の破損が頻発することにより、この改良が切実に要望されていることを課題とする。According to the present invention, since the power applied when the nut 1 is tightened by the special tool 3 is not transmitted strongly, and the special part 3 is detached from the nut 1, the convex portion 4 is frequently damaged, so that the improvement is earnestly achieved. The task is to be requested.

従来ナット頭部の凹部２を多少深く削り、凹部２に対応する凸部４を持つ専用工具底面６がナット上面５において密着することにより、摩擦を生じさせて外れ防止をしたナットである。In the conventional nut, the concave portion 2 of the nut head is cut somewhat deeply, and the dedicated tool bottom surface 6 having the convex portion 4 corresponding to the concave portion 2 is brought into close contact with the nut upper surface 5 to cause friction to prevent detachment.

請求項１のナット１によれば専用工具３の回転力が強力に伝達される。さらにナット１から専用工具３の離脱防止により、専用工具凸部４が容易に破損しないためにナット１に対してトルクを掛けられる効果がある。According to the nut 1 of the first aspect, the rotational force of the special tool 3 is transmitted strongly. Further, the prevention of the detachment of the special tool 3 from the nut 1 has an effect of applying a torque to the nut 1 because the special tool convex portion 4 is not easily damaged.

図１における専用工具凸部４を図３・図４・図５にみられる頭部に凹部２のあるナット１へ図２のように完全に刺し込むことにより、図２における専用工具底面６と図２におけるナット上面５が密着するナット・専用工具。By completely inserting the special tool convex portion 4 in FIG. 1 into the nut 1 having the concave portion 2 in the head portion shown in FIGS. 3, 4, and 5, as shown in FIG. A nut and a dedicated tool to which the nut upper surface 5 in FIG.

本考案は従来ナット１凹部２の形態を改良し、専用工具３での回転力がもっと強力に伝達される。また使用中における専用工具３の離脱における凸部４の破損が生じないように改良したものである。本考案は、また、同様のナット・専用工具にも関する。The present invention improves the form of the conventional nut 1 and the recess 2 so that the rotational force of the special tool 3 is transmitted more strongly. Also, the projection 4 is improved so that the projection 4 is not damaged when the special tool 3 is detached during use. The invention also relates to similar nuts and special tools.
