Improvement of dart lever structure

Abstract

The invention discloses an improvement of a dart rod structure of a dart, which comprises a dart tip, a dart body, a dart rod and a dart wing, wherein the dart tip is connected with the dart body, the dart body is rotationally connected and fixed with the dart rod, the dart rod comprises a main rod body and a rear end body, the main rod body is divided into at least two or more than two partial rod bodies with equal portions from the central line to the outside along the axial direction, the front end portion of the main rod body is provided with an external screw thread structure which can be rotationally connected and fixed with the dart body, the front end portion of each partial rod body is respectively provided with a screw thread which can be combined to form the external screw thread structure, the rear portion of each partial rod body is respectively hinged with the rear portion body, and the dart wing is clipped in the gap between each partial rod body after the partial rod bodies are closure. The dart can be effectively prevented from dropping out of the dart rod of the dart through adopting the structure, thereby the employment of dart can be guaranteed.

Description

technical field [0001] The invention relates to a dart apparatus, in particular to an improvement of a dart shaft structure which can effectively prevent dart wings from falling off. Background technique [0002] Darts is a kind of recreational sports and fitness equipment. Darts is an interesting and competitive leisure sport that is easy to carry out. Because its technology is simple and easy to master, it does not require special venues and facilities, and the amount of exercise is appropriate.

Problems solved by technology

Shaft 3′ as figure 2 As shown, the front end of the dart shaft 3' is provided with a screw joint 31', the screw joint 31' is an external thread structure, the dart shaft 3' is connected with the dart body 2' through the screw joint 31', and the dart body 2' Then there is an internal thread structure that can match the external thread structure of the dart shaft 3', a slit 32' is provided at the tail end of the dart shaft 3', and the dart wing 4' is inserted into the slit of the dart shaft 3'. 32' is connected with the dart shaft 3', since the dart blade 4' is usually three or four pieces, therefore, the slit 32' will be designed according to the number of blades of the dart blade 4', and the slit 32' Looking down from the tail end of the dart shaft 3', it is correspondingly designed to be Y-shaped or cross-shaped, such as image 3 , Figure 4 As shown, after the dart is installed, the dart can be thrown to the dart board. The dart has a certain speed in the process of flying to the dart board. Since the dart wing 4' is inserted into the dart shaft 3' from the tail end of the dart shaft 3' In this way, when the dart moves forward quickly, the dart wing 4' will easily fall off from the dart shaft 3', thus affecting the use of darts
