Description

Quick joint structure of pipe fittings

This creation is about a "quick joint structure of pipe fittings", especially one that assembles a simpler and faster pipe joint structure.

According to the conventional pipe fitting quick connector, it is the "pipe quick joint" of the patent certificate No. M423771 approved by the Bureau on March 1, 101, which has the following defects: its cone seat (3) The snap ring (4), the lock cap (5) and the disassembly ring (6) are separated from each other independently, so when assembling, the cone seat (3), the snap ring (4), and the lock cap (5) are required. After inserting the disassembly ring (6) into the joint body (1) one by one, the inner bend of the lock cap stopper (9) is used to stop the member from falling out, if the insertion or the inner bending process is slightly different Be cautious, it is quite easy to cause the cone (3), the snap ring (4), the lock cap (5) and the disassembly ring (6) to be dropped out at random, and the assembly will form a reverse pick and then put it. Trouble, production is quite time consuming and labor intensive.

Moreover, there is currently another type of quick fitting for pipe fittings, which is the "Improvement of the pipe joint fixing ring structure of the quick joint" approved by the Bureau of the Patent Office No. M449221 of March 21, 102, which has the following defects: The sleeve (30), the fixing ring (40) and the fixing piece (50) may be combined into one before being placed in the joint (10), but still need to be additionally combined with the guide sleeve (60) after being placed. Therefore It is also troublesome to install the guide sleeve (60) and then fall out.

Therefore, how to develop and improve the shortcomings of the above two conventional structures is really the goal of the relevant industry to develop and research. The creator has the idea of thinking and creation, and has years of experience. The design, the multi-party discussion and trial sample test, and many corrections and improvements, is the launch of this creation.

It is known that the two types of quick fittings of the pipe fittings have the trouble that the parts are placed in the joints and then fall out. This is the technical problem to be solved.

The present invention provides a quick joint structure for a pipe fitting, comprising: a joint body, an O-ring and a positioning component, and the positioning component is composed of an outer casing, a control member, a snap ring and a cover. The first and second ring protrusions are formed in one end of the joint body, and the first ring protrusion and the second ring protrusion are formed in a step shape, and the first ring is formed. The convex portion and the second annular protrusion respectively provide an O-ring and a positioning assembly to be placed on the bearing, and an inner axially through receiving space is formed in the outer casing, and a first retaining edge and a first step are arranged in the receiving space. The second retaining edge has a reduced diameter section at one end relative to the first retaining edge, and a limiting rib is arranged on the inner wall of the other end. The control member has a sleeve, and a shoulder of one end of the sleeve protrudes from the outer periphery of the sleeve. Department, the control The workpiece is placed in the accommodating space of the casing toward the outer casing, and the end of the sleeve different from the shoulder can protrude from the reduced diameter section, and the shoulder can be used against the first rib, and the workpiece can be used. To limit the control member from disengaging in the direction of the reduced diameter section, the snap ring has an annular base that abuts against the second retaining edge of the outer casing, and the inner edge of the annular base extends obliquely toward the joint body. The insert piece has a limit groove on the outer periphery of the cover, and the limit groove is provided with the limit rib, so that the cover can be fixed at the bottom of the cover shell, and the cover is used to stop the control member and the snap ring from falling out. The inner side of the cover is provided with a sloped surface, and the inclined surface is provided with a dodge, so that the inverted insert piece of the snap ring can be smoothly pushed and extended by the shoulder of the control member, thereby obtaining a quick joint structure of the pipe member. By.

The present invention provides a quick joint structure of the pipe fitting. After the outer casing, the control member, the snap ring and the cover are made, the first assembly is assembled into a positioning component, and then placed together in the opening of the joint body, so that the outer casing can be prevented. The control member, the snap ring, the cover and the like are placed in the opening and then fall out at random, which can save the trouble of being tired and re-inserted, and the assembly is simpler, more convenient, and saves time and effort. .
