Abstract

The present invention provides an arrow structure of a blower. The arrow is mainly composed of an arrow, a body and a tail. The arrow is set according to the type and form of the target, the arrow is hollow, and the arrow has a plurality of plates. The plate has elasticity; the elasticity of the plate enables proper contact with the inner wall of the pipe of the blower of the blower, so that the arrow can move stably in the blow pipe.

Description

Arrow structure

This case is related to an arrow structure of a blower, especially a stable structure at the tail of the arrow, which can stabilize the arrow in the blower.

Today, most of the general blow arrows are used in games, sports and fitness.

Such as the domestic patent 178256, 252365 and other patents related to the blow arrows, is the improvement of the blower device, including multi-section blower (or arrow) and blow arrows or blow arrows (this case is called the arrow, the following It is called an arrow; it is expected to make the arrow stable and unbiased.

As shown in Fig. 1, a conventional arrow has a long needle bar A and a tail B called a conical head; wherein the inner portion of the tail portion B is a middle groove B1 and a circular end surface B2.

The above-mentioned conventional arrow is not easy to make the arrow achieve stable flight; it is mainly difficult to make the inner diameter of the so-called end face B2 and the arrow of the blower (or the blow pipe, not shown) (this case is called If the end face B2 and the blow pipe are too tight with each other, the flight is not smooth, especially at the outlet of the blow pipe; if the distance between them is too loose or the diameter of the end face B2 is smaller than the inner diameter of the blow pipe, the arrow is easily in the blow pipe. Causes jitter and is more likely to cause bias.

The manufacture of the blowpipe may cause changes or deformations of the inner diameter due to factors such as materials, molds, or temperature, and may cause deformation of the pipe body or the like due to repeated use or external force; and the arrow, especially the round shape of the tail thereof. The so-called end face B2 is more likely to be due to materials, molds or temperatures, or even in the game. Deformation caused by various factors; therefore, the blowpipe and the arrow are not easy to cooperate well, which makes the flight of the arrow very inaccurate.

The main purpose of this case is to provide an arrow that blows arrows so that the arrow can be stably shot and stabilized.

The purpose of the arrow in this case is to make a good fit with the tube of the blowpipe and to make it flight stable.

The arrow of the present case has an arrow and a hollow tube body, and the end of the tube body forms a tail portion, and a plurality of grooves are formed on the tail portion, so that the periphery of the tail portion is formed with a plurality of plate-like bodies having elasticity, and the periphery of the tail end is The outer diameter is slightly larger than the inner diameter of the pipe body of the blow pipe; this structural feature enables the tail portion to be immediately adapted to the inner wall of the blow pipe to form a stable state disposed in the blow pipe, and can stably match the pipe diameter at any time during movement and perform stable movement. By.

The grooves in the tail of the above arrow form a flow guiding function after the arrows are blown out of the blow pipe, so that the flight of the arrow is more stable.

Figure 5: The state of the arrow of the blower in this case is in the state of the blowpipe (the blowpipe is a partial cross-sectional view).

As shown in FIGS. 2 to 5, the arrow of the present invention mainly includes an arrow 10 connected to the front of the arrow body 20, and a tail portion 30 is formed at the end of the arrow body 20.

The arrow 10 is the front section of the arrow, and the material and thickness thereof are set according to the type and form of the target (not shown), and are not limited; the arrow 20 is connected to the rear side of the arrow 10.

The front side of the arrow body 20 is connected to the arrow 10, and the rear side is formed with the tail portion 30. The arrow body 20 of the present invention has a hollow structure and has a hollow portion 21, and the shape thereof is mainly a circular tube column shape, but it is not limited thereto. The shape; the connection between the arrow body 20 and the arrow 10 is closed, that is, the front end of the hollow portion 21 is closed. The hollow portion 21 is subjected to a jet of air when blowing, causing a thrust to force the arrow to move forward.

The hollow portion 21 of the above-mentioned arrow body 20 has a plurality of lengths, and the air pressure or the jet flow at the time of blowing is stabilized to move the arrow.

The arrow body 20 starts from the middle and its tube body gradually increases rearward.

The tail portion 30 is formed at the rear end of the arrow body 20. In this case, a plurality of grooves 31 are cut in the outer edge of the columnar shape of the hollow tube, so that the tail portion 30 forms a plurality of sheets 32. These sheets 32 are elastic due to the material. The outer diameter of the tubular tail portion 30 is slightly larger than the inner diameter of the inner tube wall 41 of the blow tube 40. When the arrow is placed in the blow tube 40, the respective sheets 32 are compressed by the inner tube wall 41, and the sheet 32 is as shown in Fig. 4. The orientation is compressed about the center and is applied to the inner tube wall 41, which provides space for the sides when compressed. Since the plate 32 has elasticity, it can accommodate various states of the blow pipe 40, such as different pipe diameters, slight deformation of the pipe body, and the like.

The groove 31 as shown has a shape in which the front side has a narrower front side, and the plate 32 and the plate 32 are not mainly caused when the plate 32 is moved in the center direction by the pressing of the inner tube wall 41 of the blow tube 40. Form an overlap.

The groove 31 and the plate 32 of the tail portion 30 are not limited in shape, and are characterized in that With elasticity, the cymbal can effectively place the arrow in the inner tube wall 41 of the blow tube 40.

When the arrow is in flight, the groove 31 can also provide guiding air to stabilize the flight of the arrow.

The above embodiments of the present invention are only used to exemplify the implementation of the present invention, and to explain the technical features of the present invention, and are not intended to limit the scope of protection of the present creation. Any changes or equivalences that can be easily accomplished by those skilled in the art are within the scope of this creation. The scope of protection of this creation shall be subject to the scope of the patent application.
