Pipe fittings are a kind of accessories widely used in the connection between pipelines. Traditional pipe joints usually use threaded connections. However, threaded connections have problems such as difficult installation, hard to find installation tools, and unreliable sealing. In particular, it takes a lot of time to tighten each installation.

目前也出现有很多种结构各异的快速接头，其可快速地连接两个管路，但是现有快速接头很多都只能做到或安装、或拆卸是快速操作，无法实现安装及拆卸双向快速操作，仍然给安装和维修带来较大的麻烦；甚至此类接头体积大，对于装配空间有限的管件无法实现快拆装；还有，一些快接接头在水压变化的作用下会出现上下窜动现象，因此会出现因水道压力变动大而影响管道接头疲劳寿命的问题。At present, there are also many kinds of quick connectors with different structures, which can quickly connect two pipelines, but many of the existing quick connectors can only be installed or disassembled quickly, and cannot realize two-way quick installation and disassembly. Operation still brings great troubles to installation and maintenance; even such joints are bulky, and cannot be quickly disassembled for pipe fittings with limited assembly space; in addition, some quick-connect joints will appear up and down under the action of water pressure changes. Therefore, there will be a problem that the fatigue life of the pipe joint will be affected due to the large change of the waterway pressure.

如图1至图4所示，本发明揭示了一种管件的快接快拆接头，其包括分别与管件密封连接的一内插头1、一外接座2，以及与内插头1与外接座2同时配合的滑套3。其中：As shown in Figures 1 to 4, the present invention discloses a quick-connect quick-disconnect joint for pipe fittings, which includes an inner plug 1, anouter socket 2, and an inner plug 1 and anouter socket 2 that are sealed and connected to the pipe fittings, respectively.

所述外接座2的后部与管件密封固接，而近中部形成与内插头1前部密封配合的嵌座21，此嵌座21前部为外扩套座22；此套座22的侧壁上设有至少两个对称的卡孔221，此卡孔221是供后述滑套3的卡勾321配合，该卡孔221的高度需满足滑套3的活动距离；另在套座2各卡孔221之间的侧壁上形成有悬臂222，此悬臂222自上而下向套座2中内缩，并且各悬臂222下端围成的内径是小于内插头1环形凸台12的外径，在悬臂222的下端面便形成内插头1环形凸台12的卡制面，在形成悬臂22的套座2侧壁上亦形成有开口223，悬臂222的下端面与开口223底端之间的距离略大于内插头1环形凸台12的高度；在外接座2的套座22中，对应各卡孔221的位置在套座22的内壁上形成由套座22上端向下接通卡孔221的导槽224，而对应各悬臂22的位置在套座22的内壁上形成由套座22上端向下延伸的导向缺口225。The rear part of theouter connection seat 2 is sealed and fixed to the pipe fitting, and the near middle part forms anest 21 that is sealingly matched with the front part of the inner plug 1. The front part of thenest 21 is an outerexpansion sleeve seat 22; the side of thesleeve seat 22 There are at least twosymmetrical clamping holes 221 on the wall. Theseclamping holes 221 are used for the cooperation of theclamping hook 321 of the slidingsleeve 3 described later. The height of theclamping holes 221 needs to meet the movable distance of thesliding sleeve 3; Acantilever 222 is formed on the side wall between eachclamping hole 221, and thecantilever 222 shrinks inwardly toward thesleeve 2 from top to bottom, and the inner diameter enclosed by the lower end of eachcantilever 222 is smaller than the outer diameter of theannular boss 12 of the inner plug 1. diameter, the clamping surface of the inner plug 1annular boss 12 is formed on the lower end surface of thecantilever 222, and anopening 223 is also formed on the side wall of thesleeve 2 forming thecantilever 22, between the lower end surface of thecantilever 222 and the bottom end of theopening 223 The distance between them is slightly greater than the height of theannular boss 12 of the inner plug 1; in thesleeve 22 of theouter socket 2, the position corresponding to eachcard hole 221 is formed on the inner wall of thesleeve 22, and the upper end of thesleeve 22 is downwardly connected to the card. Theguide groove 224 of thehole 221, and the position corresponding to eachcantilever 22 is formed on the inner wall of thesleeve seat 22 with aguide notch 225 extending downward from the upper end of thesleeve seat 22.

所述滑套3是在一环面31下方对应上述的导槽224设有卡脚32，卡脚32外侧形成卡勾321以与卡孔221配合，另在环面31的下方对应上述导向缺口225延伸有凸脚33；此滑套3的内径与内插头1配合柱身14的外径相适配。Thesliding sleeve 3 is provided with aclamping foot 32 corresponding to the above-mentionedguide groove 224 under anannulus 31, and ahook 321 is formed on the outside of theclamping foot 32 to cooperate with theclamping hole 221, and the lower part of theannulus 31 corresponds to the above-mentioned guidinggap 225 is extended with a protrudingfoot 33; the inner diameter of thesliding sleeve 3 is compatible with the outer diameter of thecolumn body 14 of the inner plug 1.

所述滑套3上卡勾亦可为卡孔，则外接座2侧壁上的卡孔则为卡勾，同样可以实现二者的配合。当然，二者之间还可以凸台、凸点或其它形状等结构实现二者的配合。The hook on thesliding sleeve 3 can also be a hole, and the hole on the side wall of theouter connection seat 2 is a hook, and the cooperation of the two can also be realized. Of course, the cooperation between the two can also be realized by structures such as bosses, bumps or other shapes.

常态时，此滑套3是利用其卡脚32的卡勾321卡扣于卡孔221中，实现滑套3与外接座2的活动配合。In normal state, thesliding sleeve 3 is locked in thelocking hole 221 by thehook 321 of thelocking foot 32 to realize the movable cooperation between the slidingsleeve 3 and theexternal seat 2 .

如图3并配合图2所示，当本发明实施管件连接的安装动作时：握持内插头1将其向外接座2方向施力，则其前端是穿过滑套3而伸置于外接座2中，待内插头1的环形凸台12经过外接座2的悬臂222时，会挤压悬臂222向外形变，待此环形凸台12跨过悬臂222的下端面时，悬臂222形变恢复，悬臂222的下端面恰顶靠在环形凸台12上，环形凸台12恰位于悬臂222下端面与开口223下端之间，而悬臂222恰位于内插头1的让位缩颈13处；与此同时内插头1的前端亦与外接座2的嵌座21密封连接在一起，而滑套3下部的凸脚33受悬臂222的作用，使滑套3上部是凸伸于外接座2的上端，如此便完成了管件的快速连接。As shown in Figure 3 and in conjunction with Figure 2, when the present invention implements the installation action of the pipe connection: hold the inner plug 1 and apply force to the direction of theouter socket 2, then its front end will pass through thesliding sleeve 3 and extend to theouter socket 2. In theseat 2, when theannular boss 12 of the inner plug 1 passes thecantilever 222 of theouter seat 2, it will squeeze thecantilever 222 to deform outwardly, and when theannular boss 12 crosses the lower end surface of thecantilever 222, the deformation of thecantilever 222 will recover , the lower end surface of thecantilever 222 just leans against theannular boss 12, theannular boss 12 is just located between the lower end surface of thecantilever 222 and the lower end of theopening 223, and thecantilever 222 is just located at theconstriction 13 of the inner plug 1; and At the same time, the front end of the inner plug 1 is also sealingly connected with thenest 21 of theouter socket 2, and the protrudingfoot 33 at the lower part of thesliding sleeve 3 is affected by thecantilever 222, so that the upper part of thesliding sleeve 3 protrudes from the upper end of theouter socket 2 , so that the quick connection of the pipe fittings is completed.

此连接好的管件接头，其中内插头1是利用环形凸台12卡制在外接座2悬臂222的下端面上，当水管中的水压发生变化，环形凸台12施力悬臂222下端面时，悬臂222被限位于外接座2与内插头1让位缩颈13之间，令悬臂222没有再向外接座2中部变形的空间，因此会对环形凸台12具有一个较稳固的反作用力，从而防止内插头1在外接座2中上下窜动，保证了接头的疲劳寿命。In this connected pipe joint, the inner plug 1 is clamped on the lower end surface of thecantilever 222 of theouter socket 2 by using theannular boss 12. When the water pressure in the water pipe changes, theannular boss 12 exerts force on the lower end surface of thecantilever 222 , thecantilever 222 is limited between theouter socket 2 and the inner plug 1 to give way to the narrowingneck 13, so that thecantilever 222 has no space for deformation to the middle of theouter socket 2, so it will have a relatively stable reaction force on theannular boss 12, Therefore, the inner plug 1 is prevented from moving up and down in theouter socket 2, and the fatigue life of the joint is ensured.

当然，内插头1环形凸台12与外接座2悬臂222的配合处可为平面、斜面、台阶面或其它形状。Certainly, the matching place between theannular boss 12 of the inner plug 1 and thecantilever 222 of theouter socket 2 can be a plane, an inclined plane, a stepped surface or other shapes.

如图4所示，本发明的拆卸过程为：压下滑套3令其向外接座2中移动，则滑套3的凸脚33挤推悬臂222向外接座2的侧壁移动，令悬臂222的下端面脱离对内插头1环形凸台12的卡制，此时即可拔出内插头1，完成二者的快速拆卸动作。As shown in Figure 4, the dismounting process of the present invention is: press thesliding sleeve 3 to make it move in theouter socket 2, then the protrudingfeet 33 of thesliding sleeve 3 push thecantilever 222 to move to the side wall of theouter socket 2, so that thecantilever 222 The lower end surface breaks away from the clamping of theannular boss 12 of the inner plug 1, and now the inner plug 1 can be pulled out to complete the quick disassembly action of the two.

上述卡孔221及悬臂222并不局限于两个，亦可设置为多个，并呈圆周均匀分布的形态，同样可以实现上述功能与效果。The above-mentionedclamping holes 221 andcantilever 222 are not limited to two, but can also be provided in multiples, which are evenly distributed around the circumference, and the above functions and effects can also be achieved.

当然，滑套3与外接座2的活动配合亦不局限于卡脚32与卡孔221的配合，只要滑套3与外接座2实现防脱落配合即可。Of course, the movable cooperation between the slidingsleeve 3 and theexternal socket 2 is not limited to the cooperation between theclamping feet 32 and theclamping holes 221 , as long as thesliding sleeve 3 and theexternal socket 2 realize anti-falling cooperation.

综上，本发明通过在内插头1上设置环形凸台12，而在外接座2上设置向内伸置的悬臂222，再配合一活动配合于外接座2中的滑套3，令内插头1插于外接座2中时，由悬臂222的下端面卡制环形凸台12，实现分别连接管件的内插头1与外接座2的快速连接；需将内插头1从外接座2中拔出时，按压滑套3使之推挤悬臂222形变脱离对环形凸台12的卡制，即可拔出内插头1，实现二者的快速拆卸动作。因此该环形凸台12与悬臂222的配合，不仅实现了管件连接和拆卸快速方便，可以反复的拆装，而且令接头的结构简单、紧凑，连接可靠，防止内插头1因水压变化而在外接座2中上下窜动，保证接头的疲劳寿命。To sum up, the present invention arranges theannular boss 12 on the inner plug 1, and sets thecantilever 222 extending inward on theouter socket 2, and cooperates with asliding sleeve 3 that is movably fitted in theouter socket 2, so that the inner plug When 1 is inserted into theouter socket 2, the lower end surface of thecantilever 222 clamps theannular boss 12 to realize the quick connection between the inner plug 1 and theouter socket 2 respectively connected to the pipe fittings; the inner plug 1 needs to be pulled out from theouter socket 2 , press thesliding sleeve 3 to push thecantilever 222 to deform and break away from the clamping of theannular boss 12, and then the inner plug 1 can be pulled out to realize the quick disassembly action of the two. Therefore, the cooperation of theannular boss 12 and thecantilever 222 not only realizes the fast and convenient connection and disassembly of the pipe fittings, but also can be disassembled repeatedly, and makes the structure of the joint simple and compact, and the connection is reliable, preventing the inner plug 1 from being damaged due to changes in water pressure. Theouter connection seat 2 moves up and down to ensure the fatigue life of the joint.
