Abstract
The utility model relates to a quick joint, which comprises a main body, a sleeve and a plug; wherein, the rear end of the main body is a gas inlet; the front end of the main body is a gas outlet; the sleeve is sleeved on the rear part, which is provided with a convex shoulder, of the main body; a convex ring is arranged on the inner wall of the sleeve; the convex ring is shaped like a taper which is gradually reduced forwards; a pressure spring is arranged between the convex shoulder and the convex ring; a stopping ring is arranged on the rear ring of the sidewall of the sleeve; the rear end of the convex ring of the sleeve abuts against the stopping ring; the rear part of the sleeve is also provided with a through hole which is tapered inwards; a steel ball is filled in the through hole and pressed by the convex ring of the sleeve; and the plug, which is plugged into the main body from the gas inlet, is provided with a concave ring, in which the steel ball is clamped. The structure of the quick joint is simple, and the plug can be plugged into the main body only by pushing the sleeve, so the operation is simple.
Description
(1) technical field
The utility model relates to a kind of rapid pipe joint.
(2) background technique
Rapid pipe joint is used for realizing being connected between pipeline and the pipeline, existing quick coupling structure complexity, operation trouble very when connecting.
(3) summary of the invention
For overcome existing quick coupling structure complexity, the deficiency of troublesome poeration when carrying out attended operation, the utility model provides a kind of simple in structure, rapid pipe joint simple to operate when carrying out attended operation.
The technical scheme in the invention for solving the technical problem is: a kind of rapid pipe joint, comprise main body, the rear end of described main body is a suction port, front end is the air outlet, also comprise a sleeve, described jacket casing is located at the rear portion of described main body, the rear portion of described main body is provided with convex shoulder, the inwall of described sleeve is provided with bulge loop, this bulge loop presents the taper of shrinking gradually forward, be provided with stage clip between described convex shoulder and the bulge loop, the rear end circle of described sleeve lateral wall is provided with the retaining ring, and the rear end of the bulge loop of described sleeve is resisted against on the described retaining ring; The rear portion of described sleeve also offers the little through hole of outer imperial palace, fills out in the described through hole and is provided with steel ball, and the bulge loop of described sleeve is pressed on the described steel ball; Also comprise plug, described plug inserts in the described main body from described suction port, and this plug is provided with recessed circle, and described steel ball card is located in the described recessed circle.
When carrying out being connected of main body and plug, at first sleeve is pushed away forward, because the bulge loop that is pressed on the steel ball is the taper of shrinking gradually forward, when therefore sleeve being pushed away forward, steel ball is no longer received compacting, can smoothly plug be inserted in the main body, unclamp sleeve then, sleeve is resetted under the effect of stage clip, bulge loop is suppressed steel ball once more, steel ball is snapped onto in the recessed circle of plug, thereby plug is located.
The beneficial effects of the utility model are: simple in structure, and when carrying out the grafting of main body and plug, only need promote sleeve and get final product, operate very simple.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of rapid pipe joint, comprise main body 1, the rear end of described main body 1 is a suction port, and front end is the air outlet, also comprise a sleeve 2, described sleeve 2 is sheathed on the rear portion of described main body 1, and the rear portion of described main body 1 is provided with convex shoulder 3, and the inwall of described sleeve 2 is provided with bulge loop 4, this bulge loop 4 presents the taper of shrinking gradually forward, be provided with stage clip 5 between described convex shoulder 3 and the bulge loop 4, the rear end circle of described sleeve 2 sidewalls is provided with retaining ring 6, and the rear end of the bulge loop 4 of described sleeve 2 is resisted against on the described retaining ring 6.
The rear portion of described sleeve also offers the little through hole of outer imperial palace, fills out in the described through hole to be provided with steel ball 7, and the bulge loop 4 of described sleeve 2 is pressed on the described steel ball 7.
Also comprise plug 8, described plug 8 inserts in the described main body 1 from described suction port, and this plug is provided with recessed circle, and described steel ball 7 is fastened in the described recessed circle.
When carrying out being connected of main body 1 and plug 8, at first sleeve 2 is pushed away forward, because the bulge loop 4 that is pressed on the steel ball 7 is the taper of shrinking gradually forward, when therefore sleeve 2 being pushed away forward, steel ball 7 is no longer received compacting, can smoothly plug 8 be inserted in the main body 1, unclamp sleeve 2 then, sleeve 2 is resetted under the effect of stage clip 5, bulge loop 4 is suppressed steel ball 7 once more, steel ball 7 is snapped onto in the recessed circle of plug 8, thereby with plug 8 location.
