Embodiment 1:
As Figure 1-4, a kind of quick connector for fast interface, including push rod 11 and claw 19, claw 19 is at least provided with three, the claw 19 of described at least three can surround a catch jacket with central bore, described catch jacket is sleeved on push rod 11, claw 19 includes two ends, one end is claw end, the other end is provided with draw-in groove and grab, the profile of described push rod 11 is arranged to stairstepping periphery, it is provided with cone periphery as transition periphery between said two stairstepping periphery, relative motion can be carried out between the central bore of described catch jacket and described stairstepping periphery；Described relative motion is arranged to push rod 11 and maintains static, the central bore of described catch jacket moves up and down along the described stairstepping periphery of push rod 11, realize closing up and expansion action of described claw end as required, realize closing up and expansion action of described grab therewith；It is also set with master jaw 17 in the outside of described claw end and top along the described stairstepping periphery of push rod 11, master jaw 17 bottom has shoulder hole, between described shoulder hole and described claw end, claw position limiting structure is installed, described claw position limiting structure includes claw limit base 18 and the second spring 16, the lateral surface of claw limit base 18 is provided with step surface, described step surface is contained on end face and the medial surface of described claw end, the medial surface of claw limit base 18 has the second spring socket, equipped with the second spring 16 on described second spring socket, the other end of the second spring 16 is contained in the shoulder hole of master jaw 17 bottom；Including housing 20, claw installing hole is had on the bottom surface of housing 20 bottom, described claw installing hole is built with the claw 19 of described at least three, described claw installing hole is counterbore, described counterbore is built with the 4th O RunddichtringO 21, pore is had on the sidewall of housing 20 bottom, equipped with acting gas pipe joint 22 outside described pore, housing 20 top is provided with opening, described opening part is equipped with support 7, push-rod hole is had on the baseplane of support 7, described push-rod hole is built with push rod 6, push rod 6 top has the second pin hole, described second pin hole is built with connecting plate 2, push rod 6 top forms chain connection with one end of connecting plate 2 by the second pin 3；nullIncluding handle 5，Support 7 top is equipped with connecting stud 4，The other end of connecting plate 2 has the first pin hole，Described first pin hole is built with the first pin 1，Handle 5 is arranged on support 7 by connecting stud 4 and the first pin 1，It is provided with step surface in the middle part of the inwall of housing 20，Equipped with pad 14 on described step surface，Housing 20 includes the first spring base 10 along the structural detail that inwall is sleeved on push rod 11 from top to bottom successively、First spring 9、Pad 14、Guide collar 12、Master jaw 17、Claw 19，Installation between housing 20 with support 7 coordinates between face equipped with an O RunddichtringO 8，First spring 9 one end is connected with the first spring base 10，The other end is connected with pad 14，Equipped with the 2nd O RunddichtringO 13 between master jaw 17 top and the first spring base 10，Seal groove is had on the side of master jaw 17，Described seal groove is built with the 3rd O RunddichtringO 15，3rd O RunddichtringO 15 ensures the sealing between the side of master jaw 17 and the inwall of housing 20，Between the upper surface of the first spring base 10 and the lower surface of push rod 6 adjacent and there is certain gap when not having downforce，Fix between the end face of push rod 11 with the bottom surface of support 7 and be connected，Second spring 16 and the first spring 9 all use wire material to make，Guide collar 12 is adopted made of plastic，Support 7 and handle 5 use aluminium alloy to make.
nullOperation principle of the present utility model: when air inlet is inflated the interim inflation connection of operation needs realization，As shown in Figure 2，By downward pressing handle 5，Handle 5 is made to be rotated down with connecting stud 4 for pivot and by the first pin 1, downforce is passed to connecting plate 2，Then downforce is passed to push rod 6 by the second pin 3 on connecting plate 2，Downforce is passed to the first spring base 10 by its lower surface by push rod 6，While the first spring base 10 moves down, the first spring 9 is compressed，Meanwhile downforce is passed to again master jaw 17 by the first spring base 10、Downforce is passed to claw 19 by master jaw 17 again，So that master jaw 17 and claw 19 move down with the first spring base 10 synchronization，Push rod 11 remains and maintains static，Claw 19 makes push rod 11 enter among the inside groove of claw 19 after persistently moving down，Claw limit base 18 makes claw 19 form the state automatically closed up under the extruding of the second spring 16 promotes.As shown in Figure 1, this quick connector after closing up claw 19 is put into bottom the endoporus of the fast interface of VOSS, unclamp the aforementioned handle 5 pressed down immediately, the first spring 9 being compressed before now drives claw 19 to move upwardly along the stairstepping periphery of push rod 11 while resilience, owing to claw 19 process of moving up is as that the stairstepping periphery diameter of push rod 11 is ascending to be carried out, thus enable claw 19 also to make the grab of its lower end effectively block the snap ring within the fast interface of VOSS while opening, it is achieved thereby that the interim inflation in air inlet inflation connects.And after inflation completes, only handle 5 again need to be pressed down to make claw 19 be in automatically and extract this quick connector when closing up state, convenient to use.
From the existing quick connecting element structure of Fig. 5, this technical scheme is to pass through shackle after snap ring 24 by the conical nose of quick connection-peg 30 lower end, quick connection-peg 30 just can be made to extract therewith after first can only disassembling hollow bolt 23 when therefore needing to extract after completing inflation work, use inconvenience efficiency low.
