Description

Quick coupler
Technical field
The utility model relates to pipe fitting interconnection technique field, refers in particular to a kind of quick coupler that is applicable in liquid or the gas delivery tube road.
Background technology
In various pipelines (as water route, gas circuit etc.) transmission system, layout and installation for the ease of pipeline, often use joint to realize turning to and being connected, its form is a lot, as curved logical (as 45 °, 90 ° etc.), straight-through, threeway etc., it is isometrical that each passage can be made into, and also can be made into reducing, what application at present was wider from manufactured materials is copper pipe joint, and the connected mode of existing copper pipe joint has welded type, clamp-press type, screw-type etc.But welded type, the manufacturing of clamp-press type and screw-type joint and installation are all inconvenient, so someone has invented plug type quick coupler, the patent No. is ZL200720112409.8, its concrete structure is: joint body is arranged, the joint body two ends have joint enlarging position, put into Y shape rubber seal in the joint enlarging position successively, locating ring, the chucking circle of making by the corrosion resistant plate punching press, guide collar, locating ring will tighten circle and Y shape rubber seal is separated, in joint enlarging position, form a special sealing ring cavity, the chucking circle is V-shaped, and V-ring inwardly has barb.When installation pipeline, as long as hard tube (port need be removed burr) or flexible pipe are directly inserted in the copper pipe snap joint, the chucking circle can hook pipe, prevents that pipe is drawn out, and raises the efficiency greatly.But it still exists defective: the first, in the time will dismantling pipe,, pull out more outward that hook must be tight more on the contrary because the pipe direction of extracting is opposite with barb, and the back just can't be dismantled so in a single day pipe is in place, and maintenance, replacing bother; The second, Y type rubber seal, locating ring, chucking circle and guide collar are directly installed in the enlarging position, and are plane contact between locating ring and chucking circle and chucking circle and the guide collar, be unfavorable for installation, location, and volume are big; All channel exits of the three, one joint body all adopt spigot-and-socket to connect fast, and the scope of application is restricted.
Summary of the invention
The purpose of this utility model provides a kind of flexible pipe (as PEX pipe) or hard tube (as copper pipe etc.) and inserts behind the joint detachably, help maintenance, change, and install, the location is convenient, applied range uses snap joint flexibly.
The purpose of this utility model is achieved in that quick coupler, comprise joint body, each channel exit of joint body is shaped on the enlarging that communicates respectively, rubber seal is installed in the enlarging successively, locating ring, chucking circle and guide collar, be shaped on barb in the interior ring of chucking circle, barb contacts with pipe, guide collar extends to outside the enlarging, it is characterized in that: described chucking circle is tapered, one of guide collar is shaped on starting taper, the outer wall of starting taper contacts with the barb of ring in the taper chucking circle, at described locating ring, between chucking circle and guide collar and the enlarging lining is housed.
Guide collar is installed in the chucking circle, compact conformation, and of guide collar is shaped on starting taper, the barb cone match of the outer wall of starting taper and taper chucking circle, be easy to guiding, because guide collar extends to outside the enlarging, so as long as guide collar is pressed inwards, the starting taper of guide collar will strut the barb of chucking circle, make barb break away from pipe, at this moment pipe just can have been extracted easily, realizes detachable function, helps changing joint or maintenance.
One at described locating ring is shaped on inner conical surface, and inner conical surface contacts with the outer wall of chucking circle, and during dismounting, the starting taper of guide collar makes barb strut along the conical surface of locating ring, overexerts when preventing to extract pipe to cause the barb fracture.
Described rubber seal is an O-ring seals, meeting crush seal circle behind the pipe insertion joint, thus the sealing of assurance pipe and joints body selects for use O-ring seals more economical, practical.
Part channel outlet on the described joint body also can adopt the connected mode that is threaded or is welded to connect or blocks pressure connection or plug, and applied range uses flexibly.Described joint body is made by metal material or plastic material, in the metal material performance preferable as copper material etc., preferably engineering plastics of performance in the plastic material.
Description of drawings
Fig. 1 is a cross-sectional schematic of the present utility model;
Fig. 2 is a decomposing schematic representation of the present utility model;
Fig. 3 is the utility model and assembling schematic diagram after pipe is connected.
The specific embodiment
With specific embodiment the utility model is described further below: referring to Fig. 11:
Quick coupler, comprise joint body 10, each channel exit of joint body is shaped on the enlarging 11 that communicates respectively, rubber seal 1 is installed in the enlarging successively, locating ring 2, chucking circle 3 and guide collar 4, be shaped on barb 5 in the interior ring of chucking circle, barb 5 contacts with pipe 6, guide collar 4 extends to outside the enlarging 11, it is characterized in that: described chucking encloses 3 tapered, one of guide collar 4 is shaped on starting taper 7, the outer wall of starting taper 7 contacts with the barb 5 of ring in the taper chucking circle, at above-mentioned locating ring 2, between chucking circle 3 and guide collar 4 and the enlarging 11 lining 9 is housed.The technical program compared with the prior art, mainly be that guide collar 4 is installed in the chucking circle 3, make compact conformation, and one of guide collar 4 is shaped on starting taper 7, barb 5 cone match of the outer wall of starting taper and taper chucking circle, be easy to guiding, because guide collar 4 extends to outside the enlarging 11, so as long as guide collar 4 is pressed inwards, the starting taper 7 of guide collar will strut the barb 5 of chucking circle, makes barb break away from pipe 6, and at this moment pipe just can be pulled out easily, promptly realize detachable function, help changing joint or maintenance.One of described locating ring 2 is shaped on inner conical surface 8, and inner conical surface 8 contacts with the outer wall of chucking circle 3, and during dismounting, the starting taper 7 of guide collar makes barb strut along the inner conical surface 8 of locating ring 2, prevents to cause barb 5 to rupture because of overexerting when extracting pipe.Described rubber seal 1 is an O-ring seals, meeting crush seal circle 1 after pipe 6 inserts in the joint, thereby the sealing of assurance pipe and joints body.
Another embodiment of the present utility model is: the part channel outlet on the described joint body also can adopt the connected mode that is threaded or is welded to connect or blocks pressure connection or plug, promptly on above-mentioned joint body 10, be provided with a channel outlet at least and adopt above-mentioned connected mode (being the enlarging bayonet joint), each channel outlet of other joint body can adopt different connected modes to combine, applied range uses flexible, convenient.Described joint body is made by metal material or plastic material, in the metal material performance preferable as copper material etc., preferably engineering plastics of performance in the plastic material.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
