Title
(EN) DART HAVING REINFORCING RIB
(FR) FLÉCHETTE À NERVURE DE RENFORT
(ZH) 一种设有加强骨的飞镖
Abstract
(EN)
A dart having a reinforcing rib (5), comprising a dart body (1), a dart rod (2) connected with the dart body (1), a tail wing (3) provided on the dart rod (2), and a dart head (4) provided on the dart body (1), wherein the dart body (1) is provided with a threaded groove (11); the dart rod (2) is provided with a threaded post (21); the threaded groove (11) matches the threaded post (21); the interior of the dart rod (2) is provided with a reinforcing rib (5); one segment of the reinforcing rib (5) is located in the dart rod (2), and the other segment of the reinforcing rib is located in the threaded post (21). The dart having the reinforcing rib (5) has the following advantages: the dart is simple in structure and convenient to machine; by providing the reinforcing rib (5) in the dart rod (2), the mechanical strength between the dart rod (2) and the threaded post (21) is greatly improved, the threaded post (21) and the dart rod (2) are prevented from breaking in the process of using the dart, and the service life of the dart is prolonged.
(FR)
L’invention concerne une fléchette ayant une nervure de renfort (5), comprenant un corps de fléchette (1), une tige de fléchette (2) reliée au corps de fléchette (1), une aile de queue (3) disposée sur la tige de fléchette (2), et une tête de fléchette (4) disposée sur le corps de fléchette (1), le corps de fléchette (1) étant muni d'une rainure filetée (11) ; la tige de fléchette (2) étant munie d'un tenon fileté (21) ; la rainure filetée (11) correspondant au tenon fileté (21) ; l'intérieur de la tige de fléchette (2) étant muni d'une nervure de renfort (5) ; un segment de la nervure de renfort (5) étant situé dans la tige de fléchette (2), et l'autre segment de la nervure de renfort étant situé dans le tenon fileté (21). La fléchette dotée de la nervure de renfort (5) présente les avantages suivants : la fléchette est de structure simple et pratique à usiner ; par la présence de la nervure de renfort (5) dans la tige de fléchette (2), la résistance mécanique entre la tige de fléchette (2) et le tenon fileté (21) est considérablement améliorée, la rupture du tenon fileté (21) et de la tige de fléchette (2) est empêchée au cours de l'utilisation de la fléchette, et la durée de vie de la fléchette est prolongée.
