Described limited ring 3 is that external diameter is less than the ring body of above-mentioned joint body 22 internal diameters, its internal diameter external diameter that each tenon 61 surrounds on less than guide sub 1 greater than the external diameter of guide sub 1, corresponding above-mentioned guiding convex tendon 227 is provided with guiding groove 31 on the outer wall of limited ring 3, can only vertically move in joint body 22 to make limited ring 3; High teeth 224 at corresponding each spacing block set 221 of the front end of limited ring 3 also are formed with highly different large teeth 32 and small tooths 33 from low teeth 225, and the side faced directly of the relatively high teeth 224 of these large teeth 32 is also for facing directly equally, and opposite side is the inclined-plane; And the side that this small tooth 33 is faced directly with respect to low teeth 225 is for facing directly, and opposite side is the inclined-plane; Between two teeth just with becoming draw-in groove 34.
Described spring 4 places joint body 22 by connection block 21 pushing tows, and limited ring 3 utilizes its guiding groove 31 to cooperate with the guiding convex tendon 227 of joint body 22 and place joint body 22, this limited ring 3 is subjected to the pushing tow of spring 4 and is resisted against the rear end of each spacing block set 221, and the top of the large teeth 32 of this limited ring 3 is guide groove 222 places between two spacing block sets 221 just, and the top of small tooth 33 just is positioned at this short slot 226 places of 221 liang of teeth of spacing block set, be subjected to the different setting of each teeth height, limited ring 3 is when being subjected to the normality of spring 4 pushing tows, the inclined-plane of limited ring 3 large teeth 32 is the tops that lean in the high teeth 224 of spacing block set 221, and have the gap between the low teeth 225 of small tooth 33 and spacing block set 221, and this gap is less than the maximum outside diameter size of tenon 61.
Extremely shown in Figure 6 such as Fig. 3 a, when the utility model is implemented the quick installation action that connects of pipe fitting: grip guide sub 1 insertion that is connected with pipe fitting A and be connected with in the joint 2 of pipe fitting A, each tenon 61 of guide sub 1 is subjected to the guiding on joint body 22 each spacing block set 221 front end inclined-plane and slips in the guide groove 222, each tenon 61 just can withstand on the inclined-plane of limited ring 3 large teeth 32, continuing application of force guide sub 1 makes it to move in joint 2, limited ring 3 is subjected to the compressing of tenon 61 and moves backward and then Compress Spring 4 at this moment, make spring 4 be in the compress energy storage state, then the high teeth 224 of each spacing block set 221 are thrown off leaning limited ring 3 large teeth 32 inclined-planes, then tenon 61 just can slip in the draw-in groove 34 along large teeth 32 inclined-planes, and the front end of guide sub 1 just is sealedly attached in the connection block 21.The action that connects so fast is: the tenon 61 on the collar 6 is crossed guide groove 222, because the elastic force of spring 4 and the ramp effect of limited ring 3, the collar 6 rotates voluntarily, cancel the application of force to guide sub this moment, because spring 4 reposition force effects make the collar 6 rotate 60 degree, tenon 61 is stuck in the draw-in groove 34 of limited ring 3, finishes fast tipping and join.
Extremely shown in Figure 10 such as Fig. 7 a, quick-detachment process of the present utility model is: application of force guide sub 1, make tenon 61 place short slot 226 places, grip guide sub 1 application of force in the joint 2 this moment, each tenon 61 of guide sub 1 just can pushing tow on limited ring 3 small tooths 33 inclined-planes, limited ring 3 is subjected to the compressing of tenon 61 and moves backward and then Compress Spring 4, make spring 4 be in the compress energy storage state, when the gap between limited ring 3 small tooths 33 and the spacing block set 221 low teeth 225 during greater than the external diameter of tenon 61, be subjected to the effect on elastic force and the inclined-plane of spring 4, tenon 61 just can skid off draw-in groove 34 along small tooth 33 inclined-planes, and has aimed at the position of guide groove 222; This moment, application of force guide sub 1 was to the joint 2 outer application of forces again, and then the tenon 61 of guide sub 1 just can be deviate from joint 2 along guide groove 222, finished the quick detach operation.
Certainly, the tenon 61 in the said structure can be molded directly within on the guide sub 1, and just when assembling or dismounting, guide sub 1 needs opposing tabs 2 to be rotated can the complete operation action, can reach equally the functional requirement of quick detach fast-assembling.
In sum, pipe fitting quick detach quick fixation structure of the present utility model has following advantage:
1, connect and dismantle quick and convenient, and dismounting that can be repeatedly;
2, simple to operate, can realize automatic dismantling;
3, profile is small and exquisite, can be used in the restricted place of assembly space;
4, can use in the quick connection of PEX pipe and flexible pipe.
The above record, only for utilizing the embodiment of the utility model technology contents, modification, variation that any those skilled in the art use the utility model to do all belong to the claim that the utility model is advocated, and are not limited to those disclosed embodiments.
