Abstract
A rotary air inlet structure is characterized by comprising an air inlet connector core and an air inlet connector. The air inlet connector is sleeved at the tail end of the air inlet connector core, and the outer diameter of the tail end of the air inlet connector is matched with that of the air inlet connector core; and an O-shaped ring A is sleeved on the outer surface of a core pin of the upper end of the air inlet connector core, the core pin is inserted into a gun to be in screw joint with the gun, a shaft rail A and grooves are arranged on the outer surface of a core body at the tail end of the air inlet connector core, steel balls can be slidably placed in the shaft rail A, the section of the shaft rail A is matched with the steel balls, the grooves are arranged on two sides of a rail surface of the shaft rail A and are circularly arranged on the outer surface of the core body at the tail end of the air inlet connector core, and O-shaped rings B are sleeved in the grooves. The rotary air inlet structure has the advantages that the O-shaped rings B are placed in the grooves arranged on the two sides of the shaft rail A, so that air flowing into the rotary air inlet structure cannot escape via a gap between the air inlet connector and the air inlet connector core, the air inlet connector can rotate assuredly, and the rotary air inlet structure can be installed conveniently and is high in practicality.
Description
Technical field
The utility model relates to the air intake structure between pneumatic tool gas source pipe and the instrument, the rotary air intake structure of specifically using on a kind of electrostatic gun.
Background technique
At present, air tool air intake structure generally all adopts fixed, namely carries out spiral shell admittedly by screw thread, and following shortcoming is arranged like this: one, in use, easily gas leakage; Two, assemble very inconvenient; Three, the life-span is low.
Summary of the invention
The purpose of this utility model addresses the above problem exactly.
The technological scheme that the utility model will be dealt with problems is as follows:
Rotary air intake structure is characterized in that: comprise the air input joint core, be placed on the air input joint of air input joint core tail end and its outer diameter coupling; The core bar appearance surface cover that described air input joint core upper end insertion rifle body is spirally connected has O type circle A, described air input joint core tail end core outer surface is provided with for the axle rail A that steel ball place to slide and its section and steel ball are complementary and the groove that is located on gas joint core tail end core outer surface in axle rail A rail level both sides, is nested with O type circle B in the described groove.
Described steel ball is 13.
Be made as a section for the air input joint core upper end outer surface ring that is nested with O type circle A and be trapezoidal groove.
So that O type circle A displacement occurs at the Shi Buhui that is spirally connected, and clearance seal better effects if.
Be provided with one at air input joint housing upper end corresponding shaft rail A and run through screw, be used for placing an interior hexagonal flush end Cock screw.
By running through screw, can easily steel ball be put on the axle rail A, will run through screw by interior hexagonal flush end Cock screw again and fill up.
The position ring that the inboard correspondence in described air input joint upper end runs through screw is provided with the axle rail B that mates with steel ball.
Can conveniently place larger steel ball.
The beneficial effects of the utility model are as follows:
Compared with prior art, adopt the rotary air intake structure of the utility model structure, place O type circle B by establish groove in axle rail A both sides, so that the air that enters can not overflowed from the gap of air input joint and air input joint core, and can also guarantee the air input joint rotation, also comparatively convenient during installation, have stronger practicability.
Description of drawings:
Fig. 1 is the generalized section of the rotary air intake structure of the utility model;
Fig. 2 is the section decomposing schematic representation of the rotary air intake structure of the utility model;
Fig. 3 is that the rotary air intake structure of the utility model is installed in the partial cutaway schematic on the rifle body.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further detailed elaboration.
Consult Fig. 1 to Fig. 3.
Mode of execution one, rotary air intake structure comprises air input joint core (1), is placed on the air input joint (2) of air input joint core (1) tail end and its outer diameter coupling; The core bar appearance surface cover that described air input joint core (1) upper end insertion rifle body (3) is spirally connected has O type circle A(4), described air input joint core (1) tail end core outer surface is provided with the axle rail A(6 for steel ball (5) place to slide and its section and steel ball (5) are complementary) and at axle rail A(6) the rail level both sides are located on the groove (7) of gas joint core (1) tail end core outer surface, are nested with O type circle B(8 in the described groove (7)).
By at axle rail A(6) both sides establish groove (7) and place O type circle B(8), so that the air that enters can not overflowed from the gap of air input joint (2) and air input joint core (1), so that in use, namely rotatablely also can play a good sealing effect.
Described steel ball (5) is 13.
Mode of execution two based on mode of execution one, is used for being nested with O type circle A(4) air input joint core (1) upper end outer surface ring be made as a section and be trapezoidal groove (9).The vertical opposite side cell wall with air input joint core (1) axle of described groove (9) one side channel walls slightly tilts to axle, and vertical cell wall is against O type circle A(4) be unlikely to when air input joint (2) revolves insertion air input joint core (1), to break away from.
And O type circle A(4) displacement occurs at the Shi Buhui that is spirally connected, and clearance seal better effects if.
In fact revolve mode three, based on mode of execution one, at air input joint (2) housing upper end corresponding shaft rail A(6) be provided with one and run through screw (10), be used for placing an interior hexagonal flush end Cock screw (11).
By running through screw (10), can easily steel ball (5) be put into axle rail A(6) on, will run through screw (10) by interior hexagonal flush end Cock screw (11) again and fill up.
Mode of execution four, based on mode of execution one, the position ring that the inboard correspondence in described air input joint (2) upper end runs through screw (10) is provided with the axle rail B(12 that mates with steel ball (5)).
Described axle rail B(12) with axle rail A(6) can conveniently place larger steel ball (5) after the amalgamation.
It below only is preferred embodiments of the present utility model; should be understood that; on the basis that does not break away from the utility model basic principle; for those skilled in the art; can also make suitable improvement and moisten and fit, these improvement and profit adaptation drop within the claimed scope of the utility model.
