A traditional dart normally comprises a dart body, a dart shaft, a dart tip connected to the front end of the dart shaft and a dart flight at the tail end of the dart shaft. According to different materials of the dart tip at the front end of the dart, darts currently consist of: a hard tip dart (dart tip materials being hard metals) and a soft tip dart (dart tip materials being plastics). In each separated component of a traditional dart (a hard dart=a dart body with a metal tip+a tail shaft+a dart wing, a soft dart=a soft dart tip+a dart body+a tail shaft+a dart wing), a connection only with shorter travel of the dart body and male and female threads of the tail shaft leads to a larger concentricity deviation; moreover, a structural design integrally formed with a dart body and a dart tip leads to a fixed appearance of the dart body, and an appearance of an original dart body cannot be changed by replacing a housing.

SUMMARY OF THE INVENTION

The present invention overcomes the above-mentioned defects, and provides a dart with novel configuration which has strong stability, the color and appearance design thereof being able to be changed in various ways.

In order to solve the above-mentioned problems, the technical solutions adopted by the present invention are:

A dart with novel configuration comprises 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, the dart body and the dart shaft are 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.

Further, a piston structure is disposed on a core body of the tungsten steel inner core.

Further, the dart flight is designed to be in two types: an insertable dart flight and a nestable dart flight.

Further, 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.

Further, a dart tip body is a steel tip for a hard dart or a plastic tip for a soft tip.

Further, the dart body housing can be designed to be in any shape and color.

As can be seen from the foregoing technical solution, the advantageous effects of the present invention are:

1. The present invention combines a dart tip with a sleeve-type dart body housing integrally formed with a dart body and a dart shaft, wherein a dart structure is designed by matching a tungsten steel inner core with a steel tip for a hard dart or a plastic tip for a soft dart, and a piston-like secure connection between the sleeve-type dart housing and the tungsten steel inner core is more than 1 cm, which better ensures the concentricity of the entire dart and enhances the flight stability of the dart.

2. In the present invention, the design of multi-direction gas vents disposed on the dart body housing facilitates convection ventilation of the dart body, while reducing the probability of dart sliding caused by hand perspiration of the player.

3. The appearance and color of the dart body housing both can be designed variously, the player can vary the color and appearance of the dart just by replacing the integral-type dart body housing (dart body and dart shaft) without buying the whole set of dart again, which saves the cost of replacement of the whole set of dart.

4. The dart flight of the present invention can be designed with an insertable dart flight and a nestable dart flight, wherein the structural design of inserting the insertable dart flight into the cross slots can reduce the phenomenon of dart drop and dart shaft damage caused when the dart hits the tail shaft of the previous dart. In addition, in the present invention, multiple circular grooves are lathed at the tail end of the dart shaft from outside to inside, and such dart tail shaft with an integrated housing has multi-function compatibility. That is, in addition to using the above-mentioned insertable dart flight, the nestable dart flight can also be used. A plurality of protrusions engaged with the circular grooves at the tail end of the dart shaft are disposed on the inner ring of the sleeve, and a dart flight position can be adjusted and an overall length of the dart can be changed according to user preferences during the use; therefore, the centre of gravity and flight path of the dart can be changed.

Meanwhile, the present invention is further described below with reference to the accompanying drawings and detailed description of the invention.
