Dart with configuration

Abstract

A dart with novel configuration, including a dart body housing, dart tip connected to front end of dart body, and dart flight at tail end of dart body, wherein dart body housing is a sleeve-type structure and includes dart body at front end and dart shaft at tail end, dart body and shaft are an integrally formed structure, a plurality of gas vents are on dart body, a plurality of circular grooves are on outer surface at tail end of dart shaft from outside to inside, end at tail end thereof is in camber shape, and cross slot is designed on top end of cambered surface; dart tip includes a tip body and tungsten steel inner core connected to tip body, and is integrally mounted in sleeve of dart body housing via tungsten steel inner core; and dart flight is disposed at tail end of dart shaft.

1 . A dart with novel configuration comprising a dart body housing, a dart tip connected to the front end of the dart body and a dart flight at the tail end of the dart body, wherein, the dart body housing is a sleeve-type structure, and comprises a dart body at the front end and a dart shaft at the tail end, which are of an integrally formed structure; a plurality of gas vents are disposed on the dart body; a plurality of circular grooves are disposed on the outer surface at the tail end of the dart shaft from outside to inside, the end at the tail end thereof is in a camber shape, and a cross slot is designed on the top end of the cambered surface; the dart tip comprises a tip body and a tungsten steel inner core connected to the tip body, and is integrally mounted in the sleeve of the dart body housing via the tungsten steel inner core; and the dart flight is disposed at the tail end of the dart shaft. 
     
     
         2 . The dart with novel configuration of  claim 1 , wherein a piston structure is disposed on a core body of the tungsten steel inner core. 
     
     
         3 . The dart with novel configuration of  claim 1 , wherein the dart flight is designed to be in two types: an insertable dart flight and a nestable dart flight. 
     
     
         4 . The dart with novel configuration of  claim 1 , wherein the nestable dart flight is provided with a sleeve-type structure, and an inner ring of the sleeve is provided with a plurality of protrusions engaged with the circular grooves at the tail end of the dart shaft. 
     
     
         5 . The dart with novel configuration of  claim 1 , wherein a dart tip body is a steel tip for a hard dart or a plastic tip for a soft tip. 
     
     
         6 . The dart with novel configuration of  claim 1 , wherein the dart body housing can be designed to be in any shape and color. 
     
     
         7 . The dart with novel configuration of  claim 3 , wherein the nestable dart flight is provided with a sleeve-type structure, and an inner ring of the sleeve is provided with a plurality of protrusions engaged with the circular grooves at the tail end of the dart shaft.
