Description
- 1. Field of the Invention
- The present invention relates to a tube member, and more particularly to a gun barrel.
- 2. Description of the Prior Art
- Usually, a conventional gun barrel structure as disclosed in TWM480667 at least includes a barrel body, and two sides of the barrel body have an opening respectively. One of the openings is a conic opening tapered inward, and the other end of the openings is formed with two protruding ribs. A gun barrel can be put into the barrel body and push a bullet member through high pressure air. The bullet member is pressed by the two protruding ribs to produce a great tangential force so as to make the bullet member spin.
- However, the gun barrel structure mentioned above does not have a structure for guiding and positioning the bullet member, so the preciseness and stability need to be improved. For example, when the bullet member enters the gun barrel and is pressed by the two protruding ribs, the position and direction of the bullet member may deviate so that the bullet member is unable to move smoothly in the gun barrel. Furthermore, the kinetic energy of the bullet member may decrease due to friction and collision with an inner wall of the gun barrel, so a shot range of the bullet member may decrease, and a user may mishit a target. In addition, an inner air pressure a conventional gun barrel is too great; therefore, when the bullet member is fired, the bullet member is influenced by the air pressure and becomes unstable.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The major object of the present invention is to provide a gun barrel for guiding an air flow inside the gun barrel to make a bullet member fly stably. In addition, a number, a distance and an arrangement of vent holes may be adjusted for cooperating with various gun barrel structures to produce preferable effect. Furthermore, the gun barrel has a plurality of ramps for supporting a surface of the bullet member evenly to stabilize and balance the bullet member and for guiding and positioning the bullet member to elevate a shot range effectively and to prevent errors.
- To achieve the above and other objects, a gun barrel of the present invention is provided, including: a barrel body, having a passage therethrough, the passage being provided for a bullet member to be received and pass therethrough, two opposite ends of the passage of the barrel body being respectively formed with a bullet inlet and a bullet outlet formed by an inner wall of the barrel body surroundingly and continuously arranged, a circumferential face of the barrel body being formed with an opening, the opening being near the bullet inlet; a tangential portion, disposed at the opening restrictedly and partially movably protrusive into the passage, the tangential portion for providing friction with a surface of the bullet member tangentially; and at least one vent hole, disposed through the barrel body and being near the bullet outlet.

barrel body 10 has apassage 11 therethrough, and thebarrel body 10 may be, for example, round tubular. Thepassage 11 is provided for thebullet member 40 to be received and pass therethrough, and thebullet member 40 may be, for example, a ball-shaped bullet. Furthermore, an end of thepassage 11 of thebarrel body 10 is formed with abullet inlet 12, and the other end of thepassage 11 of thebarrel body 10 opposite to thebullet inlet 12 may be formed with abullet outlet 13 formed by an inner wall of thebarrel body 10 surroundingly and continuously arranged. Thebullet outlet 13 is annularly formed with aconic opening 131 gradually tapered inward. Thebullet member 40 can be shot and move through thebullet inlet 12 and thepassage 11 and toward thebullet outlet 13. Anopening 14 is disposed through a circumferential face of thebarrel body 10, and the opening 14 is near thebullet inlet 12. - An inner wall of the
barrel body 10 is further formed with at least oneramp 50. For example, in this embodiment, thebarrel body 10 is formed with two theramps 50, and the tworamps 50 are disposed on two opposite sides of theopening 14. Furthermore, the tworamps 50 are symmetrically arranged relative to theopening 14, and the tworamps 50 are arranged symmetrically in intervals. The tworamps 50 may be formed with an includedangle 51 therebetween. In this embodiment, the includedangle 51 may be, for example, 60 degrees, but in other embodiments, the includedangle 51 may be 90 degrees, 180 degrees or other degrees in accordance with various requirements. Theramps 50 are disposed at the bullet inlet and gradually ascend from thebullet inlet 12 toward an interior of thepassage 11. Specifically, theramps 50 are integrally recessed on the inner wall of thebarrel body 10 and disposed substantially along an axial direction of thebarrel body 10. Eachramp 50 has twoopposite slant sides 52, and an end of eachramp 50 extends to thebullet inlet 12. - The
gun barrel 1 further includes asleeve tube 60 sleeved around thebarrel body 10, and thetangential portion 20 is protrudingly disposed on an inner circumferential wall of thesleeve tube 60. Thetangential portion 20 is restrictedly disposed at theopening 14 corresponding to theopening 14 and partially movably protrusive into thepassage 11. Thetangential portion 20 is for tangentially providing friction with a surface of thebullet member 40. Furthermore, thetangential portion 20 and thesleeve tube 60 may be integrally formed, and thetangential portion 20 may be made of flexible materials, for example, rubber. - In this embodiment, a plurality of the
vent holes 30 are disposed through thebarrel body 10 and near thebullet outlet 13, and thevent holes 30 are arranged in intervals. For example, thevent holes 30 may be arranged along the axial direction of thebarrel body 10 in intervals (for example, thevent holes 30 may be arranged in equal or unequal intervals), and thevent holes 30 may be disposed through thebarrel body 10 directly and formed on two sides of thebarrel body 10. In this embodiment, thevent hole 30 may be round. Please further refer toFIGS. 6 and 7 . In other embodiments, avent hole 30 a may be oval, and avent hole 30 b may be elongate or other shapes. It is to be noted that thevent hole 30 and thebullet outlet 13 have a predetermined distance therebetween axially, and the predetermined distance extends from thebullet outlet 13 inward to a predetermined position. - In actual practice, when the
bullet member 40 passes through thebullet inlet 12 and enters thepassage 11, thetangential portion 20 abuts against and provide friction with thebullet member 40 to make thebullet member 40 move toward and abut against theramps 50. Theslant sides 52 of theramps 50 are provided for thebullet member 40 to abut thereagainst, and a ramp face of eachramp 50 and a surface of thebullet member 40 form avent gap 53 therebetween. Specifically, in this embodiment, the surface of thebullet member 40 abuts against the twoslant sides 52 of the tworamps 50 so that the surface of thebullet member 40 supports the twoslant sides 52 of the tworamps 50 evenly to stabilize and balance thebullet member 40. In addition, when thebullet member 40 is pressed and shot out toward thebullet outlet 13, thebullet member 40 spins toward a direction due to friction (as shown inFIG. 5 ). Furthermore, thevent gap 53 may be provided for an air flow to flow therethrough and further actuating thebullet member 40 to spin. - The
tangential portion 20 is pushably movable into thepassage 11. For example, thetangential portion 20 may be pushed from outside to make thetangential portion 20 further abut against thebullet member 40 and produce greater friction with thebullet member 40. It is to be noted that a pushing force that thetangential portion 20 pushes thebullet member 40 distributes to the twoslant sides 52 of the tworamps 50 evenly. Furthermore, a supporting effect of thebullet member 40 against the tworamps 50 may vary in accordance with the degree of the includedangle 51 between the tworamps 50 so that thebullet member 40 can be stably guided and supported in thebarrel body 10 and spin stably to elevate the shot range and prevent errors. The vent holes 30 allow the air flow in thebarrel body 10 to flow therethrough so as to stabilize and balance a pressure of thebarrel body 10 near thebullet outlet 13. In addition, the predetermined distance between thevent hole 30 and thebullet outlet 13 as well as the number and the arrangement of the vent holes 30 may be adjusted in accordance with different requirement to make thebullet member 40 fly stably when thebullet member 40 is shot. - Please refer to
