Description

流体管连接装置内齿卡环 技术领域 本发明涉及流体管连接装置处用于卡紧管壁的内齿卡环。 背景技术 授权公告号为 CN1324258C的第 200310101202. 7号中国专利（下称对比文件） 记载了用于引导水或气体等流体流动的流体管连接装置 （对比文件称之为 "水或 汽管连接装置")， 包括一个管接头和一个可固紧安装在管接头上的塞套， 塞套被 管道穿过后套在管壁外。 有内齿卡环 （对比文件称之为 "内齿锁紧圈 3 ") 和推齿 环 （对比文件称之为 "启闭环 2 ") 装在管接头和塞套之间。 驳接时管道穿过塞套 和推齿环后向外挤开内齿穿过内齿卡环， 接在管接头上； 若为质地较软的塑料管， 则驳接完成后内齿前端略微嵌入管壁； 若为铁管或不锈钢管， 则可以在管壁上开 槽， 让内齿前端卡入管槽内； 若为铜管， 则无需幵槽。 退出时， 需要由推齿环顺 着管道***方向推开内齿后部使内齿前端松开管壁才能取出管子。  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal toothed snap ring for clamping a pipe wall at a fluid pipe connection device. BACKGROUND OF THE INVENTION Chinese Patent No. 200310101202. 7 (hereinafter referred to as "Comparative Document") for the publication of CN1324258C describes a fluid pipe connection device for guiding the flow of a fluid such as water or gas (refer to the document as "water or steam pipe connection device" "), including a pipe joint and a plug sleeve that can be fastened to the pipe joint, the plug sleeve being passed through the pipe and then placed outside the pipe wall. There is an internal toothed snap ring (referred to as "internal locking ring 3" in the comparison file) and a push ring (referred to as "opening closed loop 2" in the comparison file) between the fitting and the plug. When the pipe is connected, the pipe passes through the plug sleeve and pushes the ring gear and then the inner tooth is pushed out through the inner toothed snap ring and connected to the pipe joint; if it is a soft plastic pipe, the front end of the inner tooth is slightly after the docking is completed. Embedding into the pipe wall; if it is iron pipe or stainless steel pipe, it can be grooved in the pipe wall to let the front end of the internal tooth snap into the pipe groove; if it is a copper pipe, no groove is needed. When exiting, it is necessary to push the toothed ring away from the rear of the pipe in the direction of pipe insertion so that the front end of the internal tooth loosens the pipe wall to take out the pipe.
现有的内齿卡环的缺陷是：  The drawbacks of existing internal toothed snap rings are:
一、 驳接时管道向外挤开内齿穿过内齿卡环， 如果内齿被挤开至接***行于 管壁， 则内齿前端难以嵌入管壁或卡入管槽， 即使勉强嵌入或卡入也达不到足够 的深度。 '而且因为内齿基本成一直线顶住管壁， 所以拆管时推齿环难以把内齿推 开， 若要强行拆除， 则须推齿环把内齿的后部推至严重变形才能使内齿松幵管壁， 但此时已损坏的内齿己经无法再卡紧管壁， 导致内齿卡环不能重复使用。  1. When the pipe is connected, the pipe is pushed outwardly through the internal toothed snap ring. If the internal tooth is squeezed to be nearly parallel to the pipe wall, the front end of the internal tooth is difficult to be inserted into the pipe wall or snapped into the pipe groove, even if it is barely embedded or stuck. Into the depth can not reach enough. 'And because the internal teeth are basically in a straight line against the pipe wall, it is difficult to push the internal teeth away when pushing the pipe. To forcefully remove, the ring gear must be pushed to push the rear part of the internal teeth to severe deformation. The tooth looses the tube wall, but the damaged internal tooth can no longer clamp the tube wall, resulting in the internal toothed ring not being reused.
二、 对质地较软的塑料管， 内齿嵌入管壁的深度无法控制， 内齿嵌入管壁太 深会伤害管壁， 甚至导致管子不能继续使用， 多次装拆后伤害更甚。 发明内容 本发明首先解决管道驳接时， 被挤开至接***行于管壁的内齿的前端难以嵌 入管壁或卡入管槽的问题， 同时解决内齿嵌入管壁的深度无法控制的问题。， . 本发明的流体管连接装置内齿卡环， 包括当管道***时被挤开的内齿， 在驳 接状态下内齿前端卡紧管壁， 其特征是， 内齿前端向管道退出方向弯折。 2. For plastic pipes with soft texture, the depth of the inner teeth embedded in the pipe wall cannot be controlled. If the inner teeth are embedded in the pipe wall too deeply, the pipe wall will be damaged, and even the pipe can not be used continuously. SUMMARY OF THE INVENTION The present invention first solves the problem that the front end of the internal tooth that is squeezed to be nearly parallel to the pipe wall is difficult to be inserted into the pipe wall or snapped into the pipe groove when the pipe is docked, and at the same time solves the problem that the depth of the inner tooth embedded pipe wall cannot be controlled. The internal toothed ring of the fluid pipe connecting device of the present invention includes internal teeth that are squeezed when the pipe is inserted, in the barge In the connected state, the front end of the internal tooth clamps the pipe wall, and the front end of the internal tooth is bent toward the pipe exiting direction.
因为本发明的内齿前端向管道退出方向弯折， 所以即使内齿后部被挤开至接 ***行于會壁， 弯折的内齿前端也可以轻易地嵌入管壁或卡入管槽。  Since the leading end of the internal tooth of the present invention is bent toward the direction in which the pipe is withdrawn, even if the rear portion of the internal tooth is squeezed to be adjacent to the meeting wall, the bent front end of the internal tooth can be easily inserted into the pipe wall or snapped into the pipe groove.
因为本发明的内齿前端向管道退出方向弯折， 使得内齿后部与前端方向不一 致， 内齿后部不能再嵌入管壁。  Since the front end of the internal tooth of the present invention is bent toward the direction in which the pipe is withdrawn, the rear portion of the internal tooth does not coincide with the direction of the front end, and the rear portion of the internal tooth can no longer be embedded in the pipe wall.
可见， -嵌入或卡入管壁的深度取决于弯折的内齿前端的长度， 所以通过设计 弯折的内齿前端的长度， 就可以让其既达到足够的深度， 又不会嵌入太深， 从而 对塑料管等质地较软的流体管起到较好的保护作用。 在此基础上， 本发明再解决内齿卡环难以被推齿环推幵， 或被强行推开后内 齿严重变形导致不能重复使用的问题。  It can be seen that - the depth of the wall embedded or snapped into the tube depends on the length of the front end of the bent internal tooth, so by designing the length of the bent front end of the tooth, it can be made to a sufficient depth without being embedded too deep Therefore, it can better protect the soft tube of the plastic tube and the like. On the basis of this, the present invention solves the problem that the inner tooth clasp is difficult to be pushed by the push ring, or the internal teeth are severely deformed after being forcibly pushed out, resulting in the inability to be reused.
所述的流体管连接装置内齿卡环， 内齿后部往靠近管壁的方向突起。  The fluid tube is connected to the inner toothed ring of the device, and the rear portion of the inner tooth protrudes toward the wall of the tube.
驳接状态下， 管壁向内齿前端施以往管道退出方向的力， 该力通过内齿前端 传到内齿后部， 使内齿后部受压迫而扭曲。 因为本发明的内齿后部往靠近管壁的 方向突起， 所以其受压迫而扭曲时突起部分会更靠近管壁 （此时内齿后部的前半 部分往往会贴住管壁）， 使内齿后部的后半部分往垂直于管轴的方向倾斜， 便于被 推齿环推开。 附图说明' 图 1是流体管连接装置的分解图。  In the docked state, the pipe wall applies a force to the front end of the inner tooth in the direction in which the pipe exits, and the force is transmitted to the rear of the inner tooth through the front end of the inner tooth, so that the rear portion of the inner tooth is pressed and twisted. Since the rear portion of the internal tooth of the present invention protrudes toward the wall of the tube, the protrusion portion is closer to the tube wall when it is pressed and twisted (the front half portion of the rear portion of the internal tooth tends to stick to the tube wall). The rear half of the rear portion of the tooth is inclined in a direction perpendicular to the tube axis to facilitate pushing away by the push ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS Embodiment 1 The fluid tube connection device of Figure 1 includes an internal toothed snap ring 1. After the fluid pipe connection is completed, as shown in FIG. 2, the inner tooth front end 3 is embedded in the pipe wall 4, wherein the inner tooth snap ring 1 is as shown in FIGS. The inner tooth front end 3 is bent toward the pipe exiting direction, and the bent inner tooth front end 3 is about 2 mm long, and the depth of the inner tooth embedded in the pipe wall 4 depends on the length of the bent inner tooth front end 3. The inner tooth rear portion 2 projects in a direction close to the tube wall 4.
驳接状态下， 管道内的流体流动使管壁 4受到管道退出方向的力， 该力通过 内齿前端 3传到内齿后部 2，使内齿后部 2受压迫而扭曲，此时内齿后部 2向靠近 管壁. 4的方向突起， 内齿后部的前半部分 5贴住管壁 4， 内齿后部的后半部分 6 往垂直于管轴的方向倾斜， 便于被推齿环 7推开。  In the docked state, the fluid flow in the pipe causes the pipe wall 4 to be subjected to the force of the pipe exiting direction, and the force is transmitted to the rear end portion 2 of the internal tooth through the front end 3 of the internal tooth, so that the rear portion 2 of the internal tooth is pressed and twisted. The rear portion 2 of the tooth protrudes toward the wall of the tube wall 4. The front half portion 5 of the rear portion of the inner tooth is attached to the tube wall 4, and the rear half portion 6 of the rear portion of the inner tooth is inclined in a direction perpendicular to the tube axis to facilitate the pushing of the tooth. The ring 7 is pushed away.
实施例二 Embodiment 2
如图 6焉本发明内齿卡环的另一种内齿结构， 内齿前端 3向管道退出方向弯 折。 本实施例的内齿后部 2基本成一直线， 造成拆管时推齿环难以推开内齿。  As shown in Fig. 6 is another internal tooth structure of the internal tooth clasp of the present invention, the inner tooth front end 3 is bent toward the pipe withdrawal direction. The inner tooth rear portion 2 of this embodiment is substantially in a straight line, which makes it difficult for the push tooth ring to push open the inner teeth when the pipe is removed.
