Description

Air tool air inlet rapid pipe joint
Technical field
The utility model relates to a kind of air tool air inlet rapid pipe joint.
Background technique
Existing pneumatic tool all is that high-pressure air pipe directly is connected on the inlet hole of instrument, and the dismounting tracheae is inconvenience very.In the time will moving instrument, the tracheae of need ining succession is moved together, and when especially moving the pneumatic tool as wind big gun and so on, because the weight of pneumatic tool own is bigger, the tracheae of in addition ining succession is moved together, and labor intensity is bigger, moves especially inconvenience.In addition, using air tool occasion, often need multiple pneumatic tool to be used together, each instrument all needs to connect a tracheae, not only operates, manages all inconveniences, and cause waste.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of simple in structure, highly versatile, the air tool fast and easily air inlet rapid pipe joint of dismounting are provided.
The purpose of this utility model realizes as follows: a kind of air tool air inlet rapid pipe joint, be characterized in forming by middle joint, Female connector fittings, air input joint, wherein the middle joint front end can cooperate with the pneumatic tool inlet hole, screw-thread fit is passed through in Female connector fittings and middle joint rear end, the air input joint front end is a cutting graftage part, this cutting graftage part places in the Female connector fittings and with the attachment hole of middle joint rear end and cooperates, and the connector portions that the air input joint rear portion is connected with high-pressure air pipe passes from the Female connector fittings rear end.
The cutting graftage part of air input joint of the present utility model is provided with seal ring.
Because middle joint can directly be contained on the air tool inlet hole, when using pneumatic tool, as long as the air input joint that will be connected on the high-pressure air pipe is connected with middle joint and pressurized gas can be inserted pneumatic tool by Female connector fittings, pass through Female connector fittings, make the dismounting of high-pressure air pipe and install all very efficient and convenient, the tracheae of ining succession in the time of can avoiding moving instrument is moved the trouble of being brought together, reduces operator's labor intensity.In addition, because this joint dismounting is efficient and convenient, in the occasion that multiple pneumatic tool is used, only needs to be equipped with a tracheae that has this joint and just can be used with multiple instrument, highly versatile and be convenient to operation and manage is avoided unnecessary waste.Compared with prior art, have simple in structure, advantages such as dismounting is efficient and convenient, highly versatile.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 expression middle joint; 2 expression Female connector fittingss; 3 expression seal rings; 4 expression air input joints.
Embodiment
The utility model will be further described below with reference to accompanying drawing and by embodiment.
With reference to Fig. 1, this air tool air inlet rapid pipe joint is made up of middle joint 1, Female connector fittings 2, air input joint 4, wherein middle joint 1 front end can cooperate with the pneumatic tool inlet hole, Female connector fittings 2 passes through screw-thread fit with middle joint 1 rear end, air input joint 4 front ends are a cutting graftage part, this cutting graftage part cooperates with the attachment hole of middle joint 1 rear end and places in the Female connector fittings 2, and the connector portions at air input joint 4 rear portions passes with tracheae from Female connector fittings 2 rear ends and is connected.In order to prevent that pressurized gas from leaking from middle joint 1 and air input joint 4 joints, is with seal ring 3 on the cutting graftage part of air input joint 4.When this rapid pipe joint is used for pneumatic tool, middle joint 1 front end is directly installed on the air tool inlet hole, the connector portions at air input joint 4 rear portions is connected with high-pressure air pipe, by Female connector fittings 2 dismounting high-pressure air pipe efficiently and easily, provide convenience for air tool use, alleviate operator's labor intensity.
