CN2720390Y - Front cover of boomerang frame - Google Patents

Abstract

The utility model relates to a front cover of a dart target frame with clean appearance and long service life, comprising a cylinder shape cover frame. The bottom edge of the cylinder shape cover frame is provided with a flange used for connection injected with the cylinder shape cover frame into integration by a metal cover net surface whose cross section is reversed V-shaped. The inner portion of the reversed V-shaped groove on the back surface of the metal cover net is injected with filling material to form a flat back surface. The utility model adopts a metal triangle net cover surface pressed by stamping process, a cylinder shape cover frame of ABS material, a fitting connection nails and a flange to form the front cover of the dart target frame by injection molding. The utility model has clean appearance and in particular suitable to be used for metal dart throwing and the game enjoyment is improved.

Description

The dart target frame front shroud

Technical field

The utility model relates to the improvement project of dart target frame front cover structure, and it can be used for various electronic flying-dartlike-weapon targets.

Background technology

Target netted cover of the prior art is with plastic material mostly, and by mould molding, this product lacks necessary texture, and in use easily because of in boomerang make the outer surface damage, cause outward appearance not beautiful, also influenced the interest of playing.

Technology contents

The utility model provides the dart target frame front mesh enclosure of a kind of flat appearance, long service life.

For achieving the above object, the utility model has adopted following technical scheme: the dart target frame front shroud, it comprises the cylindrical cover frame, there is the flange that connects usefulness at the bottom margin place of cylindrical cover frame, it is characterized in that: by the cross section is that the metal cap net and the cylindrical cover frame of inverted V-shaped is injected into one, has the injection moulding inserts to constitute the smooth back side in the inverted V-shaped groove at the metal cap net back side.

By above technical scheme as can be known, the utility model is the cylindrical cover frame that adopts metal triangular guard face that the Sheet Metal Forming Technology compacting forms and ABS material, assembles connected nail and flange, make the target body front shroud by injection moulding, the utility model not only outward appearance neat, be specially adapted to the throwing of metal boomerang pin, thereby improved the interest of recreation greatly.
