Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air gun used for the purpose of removing dust and the like by injecting compressed air to the outside, and more particularly to an air gun having a main body of an air gun, A connection pipe having one end inserted into the fixing pipe and provided in one or more than one of the connection pipes, and an air discharge pipe inserted into the end of the connection pipe to inject the compressed air, Wherein the air discharge pipe and the connection pipe are inserted into the fixing pipe so that the air discharge pipe and the connection pipe can be drawn out and inserted in multiple stages.
BACKGROUND ART [0002] Generally, an air gun is used for the purpose of removing dust and the like by injecting compressed air to the outside. The air gun has a compressed air circulation path formed therein, Respectively.
Further, a valve is provided at a rear end of the lever and is switched according to the close contact of the lever, and is provided with a lever coupled to the front portion of the body for injecting compressed air of the air gun. And a coupling end to which the nozzle is coupled while injecting the compressed air circulated through the body to the outside.
At this time, nozzles of various lengths can be coupled to the joining end of the air gun according to the application, and now, a single nozzle and an elongated nozzle have been introduced. A short nozzle is a nozzle having a short length, a body having a small outer diameter at the front and a large outer diameter at the rear, a body having a through hole formed therein, a nut at the rear outer periphery of the body, A male screw is provided with an engaging portion formed on the outer periphery.
On the other hand, the elongated nozzle is a nozzle having a long length, and a protruding tube having a length of about 20 cm is integrally formed on the front end of the nut-shaped body, and the rear end of the nut- .
Therefore, in the conventional air gun, when the long nozzle and the short nozzle are combined with each other as required, the long nozzle may be effective for jetting the compressed air in a narrow place or a narrow and long place.
However, since the elongated nozzles are fixed only by a certain length, there is a problem in that, if necessary, a nozzle having a short length or a slightly long distance is not required. There is a problem that the nozzles can not be appropriately selected in accordance with the required use because the short nozzles are too short.
Also, the conventional long nozzle and the short nozzle coupled to the air gun are not coupled to each other, and the nozzle must be stored separately.
In addition, since the compressed air is temporarily released and foreign substances such as the surrounding particles are blown out in the process of removing the foreign substances, when the air is introduced into the user's body, especially the eyes or respiratory tract, there is a possibility of causing respiratory diseases. There is a need to protect the human body from foreign matter by attaching protective equipment to one side of the air gun.
Korean Patent Publication No. 1420835 (Apr. 11, 2014) discloses a " air gun assembly having a protective film ", which is composed of an injection nozzle for ejecting high-pressure air to the outside, a main body for supporting the injection nozzle, An air supply pipe for supplying air, and a protective film detachably coupled to the spray nozzle to prevent foreign matter from being supplied to the user when air is sprayed, wherein the protective film has a coupling shaft into which the injection nozzle is inserted, And a coupling bracket coupled to the support frame and surrounding the radially outer side of the injection nozzle, and a coupling bracket for constraining the position of the injection nozzle inserted into the coupling shaft.
However, the invention disclosed in the above-mentioned prior art documents has a problem in that it can not be easily installed and disassembled due to complicated components although there is a supporting force by supporting a plurality of frames
SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide an air bag which can be suitably changed in length, And the like.
Another object of the present invention is to provide an air gun capable of minimizing the foreign matter emitted by the air pressure toward the operator during the air gun injection.
In order to achieve the above object, the present invention provides an air gun comprising: a main body of an air gun; A fixed pipe having one end attached to the main body and having a flow path for injecting compressed air to the outside; A connection pipe having one end inserted into the fixing pipe and provided in one or more than two; An air gun capable of being adjusted in length to be able to be drawn out and inserted into multiple stages by inserting the air discharge pipe and the connecting pipe into the inside of a fixing pipe, including an air discharge pipe inserted into an end portion of a connecting pipe to inject compressed air, The air discharge pipe is provided with a coating portion formed to spread in the form of a funnel so that foreign matter does not scatter to the operator and a fountain portion provided in the radial direction on the inner peripheral surface of the coating portion. And a lid extending in a funnel shape by compressed air injected from an air discharge pipe when the lid is folded side by side. The outer peripheral surface of the end of the air discharge pipe is formed with an insertion hole into which the front end of the lid is inserted, The front end of the fuselage portion is drawn into the air discharge pipe, When compressed air is being introduced into me while the compressed air is conducted to push the front end of the loan to buy incoming through the insertion hole into the interior of the air discharge pipe, characterized in that to be deployed in the form of a film an addition funnel.
Further, in order to prevent the rear end of the fixing pipe, the connecting pipe, and the air discharge pipe from completely separating from the front end of the fixing pipe, the end stop inner peripheral surface of the front end is provided with a separation preventing jaw, and the outer end surface of the rear end is provided with a fixing jaw, When the rear end is drawn out to the maximum length from the front end, one side of the fixing jaw is fixed to the side portion of the separation preventing jaw so as to be tightly fixed. In order to prevent the compressed air from being discharged to the front and rear ends, It is preferable that an O-ring is provided.
Further, the present invention is characterized in that the coated portion is made of synthetic resin or rubber material having an elastic force.
In addition, the present invention is characterized in that the coating portion is formed in a net-like shape so that the compressed air escapes to the outside of the lid opening, but foreign substances of a predetermined size or more are left inside the lid opening.
delete
According to the present invention, the length can be suitably varied as needed, and the stages are combined and stored at the time of storage, so that the convenience of use is very high and there is no fear of loss.
In addition, there is an effect that foreign matter emitted by the air pressure at the time of spraying the air gun can be minimized toward the operator.
