Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an air gun, and more particularly, to an air gun with an improved air duct.

[0002]

[Prior art]

 As shown in FIG. 5, a conventional air gun is usually attached to and detached from the main body 1 for controlling the introduction and delivery of air while grasping the air, and for guiding and supplying the air to a predetermined location. And an air supply pipe 2 or 3 which is connected as possible. That is, the air supply pipes 2 and 3 having different lengths can be exchanged according to the distance of the place where air injection is required. However, the air gun has problems such as inconvenience due to attachment / detachment at the time of conversion of the air supply pipe, and preservation of something other than the mounted air supply pipe.

[0003]

[Problems to be solved by the invention]

 In view of the above, the present invention seeks to provide an air gun whose length can be changed according to the distance of a place requiring air injection even if there is only one air supply pipe for replacement. With the goal.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention includes a main body that controls the introduction and delivery of air, and an air supply pipe that is connected and fixed to the main body so as to guide and supply the air to a predetermined location. An air gun is provided, wherein the air supply pipe is formed of a telescopic pipe. When the air gun is used, the air supply pipe can be expanded and contracted, so that the length of the air supply pipe can be changed according to the distance from the area requiring air injection without replacing the air supply pipe. Very convenient.

[0005]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the air gun of the present invention will be described in detail. FIG. 1 shows a preferred embodiment of the air gun of the present invention, and FIG. 2 shows a partial cross-sectional view thereof. As shown in FIGS. 1 and 2, the air gun of the present embodiment mainly has a grasping unit, and can control the introduction and delivery of air by a trigger 20, and can guide and supply the air to a predetermined location. And an air supply pipe 40 connected and fixed to the main body 10 as described above.

More specifically, the air supply pipe 40 includes an outer pipe 41 and an inner pipe 42. The outer pipe 41 has a straight pipe shape, one end 411 of which is connected and fixed to the main body 10, and the other end of which is a waveform contraction port 413. The inner tube 42 has a curved shape, and includes a first portion 422 having a jet-shaped injection port 421 at a tip thereof, and a second portion 424 inserted into the outer tube.

The second part 424 is a straight pipe body whose end 423 is enlarged like a mouth, and a valley 416 of a corrugated contraction port 413 of the outer pipe 41 is connected to the inner pipe 42. An O-ring 43 is provided, which is in constant contact with the outer tube 41 and the inner tube 42 to make the space between the outer tube 41 and the inner tube 42 airtight. Thereby, as shown in FIG. 2, the lip-shaped end 423 is slidably and rotatably fitted with the inner wall of the outer tube 41.

That is, as shown in FIG. 3 and FIG. 4, the air supply pipe 40 connects the inner pipe 42 until the rasp-shaped end 423 is blocked by the corrugated contraction port 413 as necessary. The outer tube 41 is rotated after being extended along the axis of the outer tube 41, and air can be ejected from the ejection port 421 to a target location under the control of the trigger 20.

In this embodiment, the air supply pipe 40 is of a telescope type having two pipes, an outer pipe 41 and an inner pipe 42, but may be a pipe having three to three or more pipes.

[0010]

[Effect of the invention]

 As described above, the air gun of the present invention sends the air by rotating the inner pipe 42 while expanding and contracting it along the axis of the outer pipe 41 in accordance with the distance and position of the point where air injection is required. The length of the entire trachea and the position of the injection port or the injection direction can be changed.

While the present invention has been fully described above with reference to the preferred embodiments and with reference to the accompanying drawings, various modifications and alterations will be apparent to those skilled in the art. is there. It is to be understood that such variations and modifications are included therein without departing from the scope of the invention as set forth in the appended claims.
