Description

A boomerang for outdoor sports

technical field

The invention belongs to the technical field of outdoor sports equipment, and relates to a boomerang for outdoor sports.

Background technique

The boomerang, also known as the boomerang, is one of the ancient hunting tools. The Australian aborigines were the first to use hardwood to make boomerangs. They used this tool to capture small animals; the boomerang flies in an arc after it is thrown, and if it does not hit The target will change direction again and return to the hands of the original holder.

Chinese Patent (Announcement No.: CN201658804U; Announcement Date: 2010-12-01) discloses a boomerang, which includes a solid keel made of a hard material and a covering body made of a soft material. Covered on the outside of the keel; the shape of the keel matches the shape of the boomerang; the material of the covering body adopts foamed polyurethane, and the material of the keel adopts polyethylene plastic.

The functions of the boomerangs disclosed in the above patent documents are relatively simple, which makes people feel that the sport of throwing boomerangs is not very interesting.

SUMMARY OF THE INVENTION

Aiming at the above problems existing in the prior art, the present invention provides a boomerang for outdoor sports. The technical problem to be solved by the present invention is: how to increase the fun of the sport of throwing boomerangs.

The object of the present invention can be realized through the following technical solutions:

A boomerang for outdoor sports, comprising a boomerang main body, characterized in that the boomerang main body comprises a left wing and a right wing, the ends of the left wing and the right wing are butted to form a V shape, and the upper sides of the left wing and the right wing are in a V shape. Both are planes, the lower sides of the left and right wings are inclined surfaces, and the thicknesses of the left and right wings gradually increase from the outer end to the butt end; Block 1, the width of the slider 1 is smaller than the width of the left wing, the slider 1 can slide back and forth on the upper side of the left wing; the upper side of the right wing is provided with a slider 2 along the length direction of the right wing , the width of the slider 2 is smaller than the width of the right wing, the slider 2 can slide back and forth on the upper side of the right wing; the opposite end surfaces of the slider 1 and the slider 2 are respectively fixed with racks 1 and rack 2, the rack 1 and rack 2 are arranged in parallel and spaced apart, and there is a rotating gear between them that meshes with the rack 1 and rack 2 at the same time, and the center of the rotating gear is fixed There is a gear shaft, the lower end of the gear shaft extends through the boomerang body to the bottom of the boomerang body, and the gear shaft can move up and down in the boomerang body; The rotating gear is fixed to the fastener on the boomerang body.

Its working principle is as follows: the boomerang used for outdoor sports in this technical solution, when the rotating gear is located between the first rack and the second rack and meshes with the first rack and the second rack, the gear shaft is rotated clockwise, and the rotating gear is clockwise. Rotation will make slider one slide forward on the left wing, and slider two slide backward on the right wing. When the front side of slider one is flush with the front side of the left wing, the rear side of slider two is flush with the rear side of the right wing. Flat, tighten the fasteners; or turn the gear shaft counterclockwise, the rotating gear counterclockwise will make the slider 1 slide backward on the left wing, the slider 2 slides forward on the right wing, and the rear side of the slider 1 is connected to the left wing.
