Quick joint structure of pipe fittings

This creation is about a "quick joint structure of pipe fittings", especially a quick joint structure of pipe fittings that is easier to press.

According to the fact that in view of the shortcomings of the traditional quick fittings of pipe fittings, the creator has developed a quick joint structure of the pipe fittings which is modularized first and is easy to assemble. The structural form is as shown in the eleventh to the first The fourteenth figure, or the national patent certificate number No. M485335, mainly includes: a joint body (10), an O-ring (20) and a positioning component (30), and the positioning component (30) Is composed of a combination of a cover (31), a control member (32), a snap ring (33) and a cover (34), wherein the joint body (10) is formed with an opening (11) at one end thereof, and is open (11) a first ring protrusion (12) and a second ring protrusion (13) are provided, and the first ring protrusion (12) and the second ring protrusion (13) are arranged in a stepped manner. A ring protrusion (12) and a second ring protrusion (13) respectively provide an O-ring seal ring (20) and a positioning assembly (30) to be placed on the bearing, and an inner axially through receiving space is formed inside the outer casing (31) ( 311) The first rib (312) and the second rim (313) are arranged in the accommodating space (311), and one end is provided with a reduced diameter section at the first rim (312). 314), the other end of the inner wall is limited Rib (315), the control member (32) having a sleeve (321), the sleeve (321) protrudes from an end of an outer periphery of a shoulder (322) of the outer inclined guide surface, The control member (32) is inserted into the accommodating space (311) of the outer casing (31) with the sleeve (321), and the end of the sleeve (321) different from the shoulder (322) can be reduced from the diameter reducing section. (314) extending, using the shoulder (322) and the first retaining edge (312), can also be used to limit the control member (32) does not detach from the diameter reducing section (314), the snap ring (33 ) having an annular base (331) against the second retaining edge (313) of the outer casing (31), the inner edge of the annular base (331) extending obliquely toward the joint body (10) A plurality of inverted inserts (332) are provided with a limit groove (341) on the outer periphery of the cover (34), and the limit groove (315) is provided by the limit groove (341) to enable the cover (34) to be closed. It is fixed to the bottom of the outer casing (31), and is used for stopping the control member (32) and the snap ring (33) from falling out. On the inner end of the cover (34), a slope (342) is provided on the inclined surface ( 342) Providing a dodge, so that the inverted insert piece (332) of the snap ring (33) can be smoothly pushed by the shoulder (322) of the control member (32); when combined, the O-ring (20) and positioning The assembly (30) is sequentially placed into the opening (11) of the joint body (10), and the outer casing (31) is pressed and fixed by the formation of the beam edge (14) of the joint body (10).

However, after the developer created the creation case, he was not complacent, and continued to think about R&D in the spirit of excellence, striving to make this structural feature more vivid and easy to use; During the process, it is found that the sleeve (321) protruding from the outer diameter reducing section (314) provides a pressing force in the above-mentioned prior structure, and the crucible is used to sway the tubular member (60) to be disengaged (as shown in Fig. 15). There is a problem that the contact area of the side end of the sleeve (321) is too small and the pressing is relatively difficult, so it is necessary to improve the breakthrough.

Therefore, the person who wants to reveal this creation is a new type of structural designer who has made improvements and breakthroughs in the shortcomings of the creator's related previous case structure.

It is mainly to improve the breakthrough point of the problem that the sleeve pressing of the conventional pipe fitting quick joint developed by the creator is not easy.
