The body is a cylinder having a cavity inside, and has one end being a step-type through hole. The bottom of the step-type through hole has a fixing insertion hole (11) for insertion of an external pipe (6). The diameter of the fixing insertion hole (11) is smaller than that of the cavity, so as to form a step (12). The seal ring (2) is placed on the step (12). An upper portion inside the step-type through hole is sequentially provided with the cap (4), the clip (5), and the snap (7) as required. An upper end of the seal ring (2) is further additionally provided with a fixing structure (3) through which the pipe (6) can run. When the quick connector is in use, if the pipe outside the quick connector is bent due to an external force, the pipe inside the body of the quick connector is firmly fixed and gripped by the fixing structure and the fixing insertion hole, so that the seal ring is not deformed by the exerted force, and the problem of water leakage incurred by deformation of the seal ring is avoided. The connector is simple in structure, and convenient for machining and installation.

Description

一种防止水渗漏的快速接头 技术领域  Quick joint for preventing water leakage
本发明涉及一种应用于涉水环境的快速接头， 尤其是指一种水家电净 水器 （机） 设备中的防止水渗漏的快速接头， 属于涉水配件技术领域。 背景技术  The invention relates to a quick joint applied to a wading environment, in particular to a quick joint for preventing water leakage in a water appliance water purifier (machine) equipment, and belongs to the technical field of water-related accessories. Background technique
快速接头， 又称为推入式管件， 因其操作便捷、 连接完美紧凑且可反 复使用等优势被应用于很多领域。  Quick couplings, also known as push-in fittings, are used in many applications due to their ease of operation, perfect connection and reusable use.
在涉水环境中， 很多水家电净水机 （器） 中， 管路之间的连接也是应 用快速接头来实现的， 尤其是近年来广为消费者所青睐的各种净水机器， 如； 家用逆渗透 （反渗透） 净水机， 逆渗透技术： 逆渗透原文是 REVERSE OSMOSIS (简称 R0)， 原理是在原水一方施加比自然渗透压力更大的压力， 使水分子由浓度高的一方逆渗透到浓度低的一方 。 通常， 逆渗透净水机 是通过 1个 PPF溶喷滤芯 2个活性炭滤芯 （1个颗粒活性炭、 1个烧结活 性炭） 等， 对原水进行预过滤， 再对预过滤水施加压力 （通过增压泵） 令 其通过孔径大小为万分之一微米的反渗透膜， 即 R0膜。 各个滤芯之间、 滤芯与 R0膜之间、滤芯与入水口以及 OR膜与出水口之间等等管路的连接 均是使用快速接头。 然而， 受整个净水机体积所限， 滤芯的排列很紧凑， 因此各个管路常常处于被强力弯曲的状态， 加上管路中水流的压力较大， 久而久之， 致使快速连接头内的密封圈因单边受力而变形， 如图 1所示， 密封圈受管子的长期弯曲压迫密封圈加上又受季节性温差变化及热胀冷 縮后的老化影响， 导致密封圈变形， 渐渐失去密封作用而造成渗漏现象。 而导致产品漏水之后不仅给使用者造成不便， 更为严重的是有可能水会渗 入增压泵及其它的电路接线中， 导致烧毁电机， 或造成整机设备漏水而无 法使用。 In the wading environment, in many water appliance water purifiers, the connection between the pipelines is also realized by the application of quick joints, especially the various water purifying machines that are widely favored by consumers in recent years, such as; Household reverse osmosis (reverse osmosis) water purifier, reverse osmosis technology: reverse osmosis text is REVERSE OSMOSIS (referred to as R0), the principle is to apply a greater pressure than the natural osmotic pressure on the raw water side, so that the water molecules are reversed by the higher concentration Penetrate to the lower concentration side. Usually, the reverse osmosis water purifier is pre-filtered with raw water through two activated carbon filter elements (one granular activated carbon and one sintered activated carbon) of one PPF spray filter, and then applies pressure to the pre-filtered water (via a booster pump). It is passed through a reverse osmosis membrane having a pore size of one ten thousandth of a micron, that is, an R0 membrane. The quick connection is used for the connection between the various filter elements, between the filter element and the R0 membrane, between the filter element and the water inlet, and between the OR membrane and the water outlet. However, due to the volume of the entire water purifier, the arrangement of the filter elements is very compact, so each pipe is often in a state of being strongly bent, and the pressure of the water flow in the pipe is large, and over time, the seal ring in the quick connector is caused. Deformed due to unilateral stress, as shown in Figure 1, the seal is compressed by the long-term bending of the tube and is affected by the seasonal temperature difference and the aging after thermal expansion and contraction, resulting in deformation of the seal and loss of sealing. Leakage caused by action. After the product leaks, it not only causes inconvenience to the user, but more seriously, the water may penetrate into the booster pump and other circuit wiring, causing the motor to be burnt, or the whole device may be leaky and cannot be used.
因此， 解决上述快速接头渗漏水的问题， 具有重要的现实意义。  Therefore, solving the above problem of leakage of the quick joint has important practical significance.

本发明所述的快速接头， 具体为一种 " L"型的快速接头， 如图 2、 3 所示， 它具有 A、 B两个端口。 本实施例以端口 A来说明本发明的快速接 头的形状构造。 本发明一种防止水渗漏的快速接头， 其包括本体 1、 密封 圈 2、 固定结构 3、 盖帽 4、 夹扣 5、 卡扣 7。  The quick connector of the present invention is specifically an "L" type quick connector, as shown in Figures 2 and 3, which has two ports A and B. This embodiment illustrates the shape configuration of the quick connector of the present invention by port A. The invention relates to a quick joint for preventing water leakage, which comprises a body 1, a sealing ring 2, a fixing structure 3, a cap 4, a clip 5, and a buckle 7.
本体 1是一个内部带有通水空腔的筒体， 在其一端 （即 A端） 为台阶 型通孔，在该台阶型通孔的底部具有由本体外部插入管子 6的固定插孔 11， 该固定插孔 11的深度为 6 mm, 其直径较通水空腔的直径小， 进而形成一 台阶 12， 密封圈 2放置于该台阶 12处； 再往上的台阶型通孔内按要求依 次设置固定结构 3、 盖帽 4、 夹扣 5和卡扣 7; 在盖帽 4与固定结构 3之间 预留一夹扣活动空间 8。 The body 1 is a cylinder having a water-passing cavity inside, and has a stepped through hole at one end thereof (ie, the A end), and a fixing insertion hole 11 for inserting the tube 6 from the outside of the body at the bottom of the stepped through hole, The fixing socket 11 has a depth of 6 mm and a diameter smaller than that of the water-passing cavity, thereby forming a step 12, and the sealing ring 2 is placed at the step 12; The fixing structure 3, the cap 4, the clip 5 and the buckle 7 are provided in a secondary manner; a clip movable space 8 is reserved between the cap 4 and the fixed structure 3.
使用所述的快速接头与管子连接时， 外部的管子 6依次穿过夹扣 5、 盖帽 4、 固定结构 3和密封圈 2后， 最终被插置进入固定插孔 11内， 然后 在盖帽 4和夹扣 5之间置入卡扣 7， 致使夹扣 5内径上的金属爪会卡住管 子 6， 实现快速连接。位于本体空腔内部的管子 6被固定插孔 11和固定结 构 3这两处将管子固定抱住， 当快速接头外部的管子受外力而弯曲时， 位 于快速接头内部 （即空腔内） 的管子由于有该两处固定而被牢牢抱住， 使 得位于固定插孔 11和固定结构 3之间的密封圈 2不会受力变形， 这样就 避免了密封圈因变形产生缝隙从而导致水的渗漏等问题， 如图 5所示。  When the quick connector is used to connect the tube, the outer tube 6 passes through the clip 5, the cap 4, the fixing structure 3 and the sealing ring 2 in sequence, and is finally inserted into the fixing socket 11, and then in the cap 4 and A snap 7 is placed between the clips 5 so that the metal claws on the inner diameter of the clip 5 catch the tube 6 for quick connection. The tube 6 located inside the cavity of the body is fixedly held by the fixing socket 11 and the fixing structure 3, and the tube located inside the quick connector (i.e., inside the cavity) when the tube outside the quick connector is bent by an external force. Because the two places are fixed and tightly held, the sealing ring 2 located between the fixing socket 11 and the fixing structure 3 is not deformed by force, thus avoiding the gap of the sealing ring due to deformation and causing water seepage. Leakage and other issues, as shown in Figure 5.
