Description

一种锁紧式快速接头Locking quick connector 技术领域Technical field
本发明涉及机械技术领域,更具体而言,特别涉及一种锁紧式快速接头。The present invention relates to the field of mechanical technology, and more particularly to a locking quick connector.
背景技术Background technique
在日常生活中,流体的传输均需要通过管道系统进行。而在整个管道系统中,由于受到长度的限制,都是由多段管道构成,多段管道之间的连接需要通过接头等管件进行。为了达到管道安装方便的目的,人们设计了各种快速接头。已有快速接头的结构大多由接头本体,以及安装在本体内的呈环状分布倾斜向内的倒齿片和在倒齿片位于接头本体口部一侧设置的卸套构成。安装水管时,水管插入接头,水管外壁推挤倒齿片张开,到位后倒齿片卡住水管外壁,使之不能拔出,达到快速链接的目的。若要拔出水管,则利用管径大于水管的卸套挤压倒齿片,使之失去卡紧力,从而将水管拔出。但这种快速接头也存在着缺陷。倒齿片仅能卡住硬度较低材料所制成的管材,如不锈钢、铜管等硬度高的管材则不能可靠连接,并且倒齿片容易划伤水管表面,影响密封性。In daily life, the transfer of fluids needs to be carried out through a piping system. In the whole pipeline system, due to the limitation of length, it is composed of a plurality of sections of pipelines, and the connection between the sections of pipelines needs to be carried out through pipes such as joints. In order to achieve convenient pipe installation, various quick connectors have been designed. Most of the structures of the quick joints are composed of a joint body, and an inverted tooth piece which is disposed in the body and which is inclined inwardly and inwardly disposed, and a unloading sleeve which is disposed on the side of the mouth of the joint body. When the water pipe is installed, the water pipe is inserted into the joint, and the outer wall of the water pipe pushes the inverted tooth piece to open. When the position is reached, the inverted tooth piece catches the outer wall of the water pipe, so that it cannot be pulled out, and the purpose of quick link is achieved. To pull out the water pipe, use the unloading sleeve with a pipe diameter larger than the water pipe to squeeze the inverted tooth piece to lose the clamping force, thereby pulling out the water pipe. However, such quick connectors also have drawbacks. The inverted tooth piece can only catch the pipe made of the material with lower hardness. The high hardness pipe such as stainless steel and copper pipe cannot be reliably connected, and the inverted tooth piece is easy to scratch the water pipe surface and affect the sealing property.
为了提高管材与接头的连接牢固性,传统方法是通过在接头端部外围轴向锁定位置加工环型凹槽的工艺,当管材插入接头内时,齿形卡圈切入凹槽来提高连接的牢固性。其承口由衬套、卡圈、靠垫、O型圈、卸套等组成,结构复杂,制造工艺要求高。虽然适用范围广,但连接可靠性差。In order to improve the connection stability of the pipe and the joint, the conventional method is a process of processing the ring-shaped groove by axially locking the position at the outer end of the joint. When the pipe is inserted into the joint, the toothed ring is cut into the groove to improve the connection. Sex. The socket is composed of a bushing, a snap ring, a cushion, an O-ring, a unloading sleeve, etc., and has a complicated structure and high manufacturing process requirements. Although the scope of application is wide, the connection reliability is poor.
