Description
Technical field
The utility model relates to a kind of pipe fitting with plug type quick coupler, the groove of Sealing in particularly a kind of joint middle joint nut, lock tube pipe and the joint inner chamber of the pipe fitting with plug type quick coupler.
Background technique
Root tool purposes difference, pipe fitting have elbow, straight-through, threeway, four-way, valve etc.Pipe fitting has pipe fitting, the useful joint that links to each other with pipeline on the pipe fitting, and different pipe fittings has different pipe fittings.Plug type quick coupler easily is used for being connected of pipe fitting and plastic tube, and plug type quick coupler should guarantee sealing and the join strength that pipe fitting is connected with pipeline.In the prior art, Chinese patent ZL00 251191.6 discloses a kind of pipe fitting with plug type quick coupler, this pipe fitting with plug type quick coupler has pipe fitting, the useful joint that links to each other with plastic tube of pipe fitting, connection port has outside thread, be rotary with collar nut on the outside thread of connection port, the collar nut inwall has the hoop inclined-plane coaxial with collar nut, be with the lock tube pipe coaxial in the collar nut with collar nut, the inner of lock tube pipe is evenly equipped with axially cracks, make this end of lock tube pipe be evenly equipped with the elasticity fork, the mouth of pipe outside, two ends of lock tube pipe has fin respectively, in the inner fin of the lock tube pipe outside hoop inclined-plane coaxial with the lock tube pipe is arranged, in the inner fin of lock tube pipe inboard, along hoop radially steel tenon is arranged, at the joint inner chamber circumferential step is arranged, y-shaped ring is arranged in the circumferential step.This pipe fitting with plug type quick coupler has following deficiency:
1, the outside fin of lock tube pipe the inner does not contact with annular slope on the inwall of collar nut, when the joint of this pipe fitting is connected with plastic tube, the inner inboard radially steel tenon of lock tube pipe can not be subjected to being stuck in the radial force on the plastic tube wall, thereby join strength is low, perhaps can allow the outside diameter of plastic tube interference be arranged than inner inboard radially place, the tip circular diameter of steel tenon of lock tube pipe, make radially that the steel tenon clamps plastic tube because of above-mentioned size interference is subjected to radial force, but can make plastic tube plug difficulty like this;
2, in the ring-shaped step of y-shaped ring in joint, its lip does not have the lip seal groove, and sealing reliability is poor;
3, accompany jump ring between the lug, nib of collar nut and the lock tube pipe outer end outside,, make plastic tube and pipe fitting joint very inconvenient when plug in order to keep the relative position between collar nut and lock tube pipe.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of joint when being connected with plastic tube, the pipe fitting that plug is convenient, join strength is high, reliable sealing has plug type quick coupler.
The utility model is realized with the following method.
Pipe fitting with plug type quick coupler can be an elbow, straight-through, threeway, four-way, valve etc., pipe fitting with plug type quick coupler has pipe fitting, the useful joint that links to each other with pipeline on the pipe fitting, connection port has outside thread, be rotary with collar nut on the outside thread of connection port, the internal thread that matches with the connection port outside thread is arranged in the collar nut, on the collar nut inwall, the inside hoop inclined-plane coaxial with collar nut, inclined-plane arranged, the joint inner chamber has the circumferential step coaxial with joint, the outer lip seal groove coaxial with circumferential step arranged at the circumferential step bottom, y-shaped ring and back-up ring are arranged on the circumferential step, the outer lip of y-shaped ring is inserted in the outer lip seal groove, the lock tube pipe coaxial with collar nut arranged in the collar nut, the inner of lock tube pipe is evenly equipped with isometric axially cracking, make the inner of lock tube pipe be evenly equipped with the elasticity fork, there is fin in the outside in the inside and outside port of lock tube pipe, the fin outside at lock tube pipe inner port place, the outside hoop inclined-plane coaxial with the lock tube pipe, inclined-plane that matches with hoop inclined-plane on the collar nut inwall arranged, fin inboard, lock tube pipe inner port place, along hoop radially steel tenon is arranged, radially the external diameter of the plastic tube that cooperated of place, the tip diameter of a circle of steel tenon and pipe fitting joint equates.
During use, one end of the plastic tube that will link to each other with this pipe fitting is inserted in the lock tube pipe of this pipe fitting joint, allow plastic tube be inserted in y-shaped ring and radially in the steel tenon place circle, inside swivel joint nut, hoop inclined-plane in the collar nut can inwardly slide along the hoop inclined-plane in the lock tube pipe fin outside, when inwardly sliding, produce radial component, act on the lock tube pipe fin, the radially steel tenon of fin inboard is pressed on the plastic tube outer wall, when from pipe fitting joint, extracting plastic tube as need, outside swivel joint nut, hoop inclined-plane in the collar nut outwards slides, the radially steel tenon of lock tube pipe fin inboard loses external force, unclamps the pressure to plastic tube, and plastic tube is extracted in the lock tube pipe.
Place, the steel tenon tip diameter of a circle of the utility model lock tube pipe fin inboard equates with the external diameter of the plastic tube that pipe fitting will be connected, so plug easily; This pipe fitting is with after plastic tube is connected, and lock tube pipe fin inboard radially steel tenon is subjected to radial force to be pressed on the plastic tube outer wall even can punctures the outer wall of plastic tube, inserts in the tube wall a little, and institute is so that the join strength height of this pipe fitting and plastic tube; The outer lip of y-shaped ring mouth has seal groove, and it is more reliable to make pipe fitting be connected the back sealing with plastic tube; Pipe fitting is to rotatably compress with collar nut with after plastic tube is connected, without the jump ring location, so plug is convenient.
Below in conjunction with accompanying drawing, the utility model is further described.
