The quick connector includes a tubular joint body 3 for connecting the two tubular members to the two ends thereof, a set of spring claws 4 positioned outside the joint body 3, and a sleeve axially displaceable The sleeve 5 is limited to the outside of the joint body 3 and is sleeved outside the spring claw 4 . The joint body 3 has a first end portion 31 and a second portion 4432 which are vertically opposite to each other, and an inner portion thereof defines an axially extending communication duct 3〇, and the first end portion 31 is symmetrically pierced with three radial passages. The perforations are 31 turns and have an upwardly facing positioning surface 311. The spring claw 4 has a coaxial sleeve disposed outside the first end portion 31 and abuts against the annular ring portion 41 located on the positioning surface 311, and three symmetrically distributed from the positioning ring portion 41. The elastic clamping jaws 42 disposed in the perforations 310 and the elastically-retaining elastic arms extending in a pair of symmetrically spaced upwardly from the positioning ring portion 41 are disposed. The female-claw portion 42 has a self-positioning ring portion 4" a main protruding portion and a radially elastic yaw portion 421' and a fixed portion of the swing arm portion 421 and a diameter 201125234 embedded in the through hole 310 A block segment 422, and the block segment 422 can be partially inserted into the communication pipe 3〇. The pair of reset spring arms 43 are respectively disposed between the two adjacent jaw portions 42 and each of the pair of complex arm portions 43 can be pushed up by the outer sleeve 5, respectively, and the opposing elastic yaws are close to each other, in pairs The two reset spring arm portions 43 respectively have abutting slopes which are inclined away from the upper side of the positioning ring portion 41. The outer sleeve 5 has an axially displaceable sleeve at the first end portion 31. The tube body 51 which is externally sleeved against the spring claws 4, three symmetrical protrusions protruding from the inner circumferential surface of the tube body 51 and which are difficult to face (4) against the pinch claw portion 42 and three symmetrical protrusions The inner peripheral surface of the tube body 51 and the bottom portion thereof respectively abut against the abutting unit 53 of the pair of reset spring arms 43 , and the outer sleeve 5 can be in the loose position and the buckle position relative to the elastic claw 4 The axial displacement changes up and down. The ejector blocks 52 are spaced radially outward of the swing arm segments 42 ι of the jaw portions 42 and respectively press radially inwardly against the outer side of the block segments 422 of the jaw portions 42 to force the block segments 422. The inward displacement through the perforations 31 局部 partially penetrates into the communication duct 30 'to enable the card segments 仏 to be used to position the snaps to the tubular members that have been inserted in the joint body 3, while at the same time the swing arm segments The 421 will be interlocked by the radially inwardly moving block segments 422, and will be radially deflected inwardly and accumulate a return spring force. Each of the push-up sheets 7L 53 has two ribs 53 extending from the upper and lower sides and extending in parallel at intervals on the inner circumferential surface of the pipe body 51, and the bottom ends of the urging ribs 531 are respectively downwardly elastically pressed against the pair of reset materials. The phase of the portion 43 (4) the slanting surface 201125234 430 〇 Referring to Figures 3, 4, 5, when the outer sleeve 5 is in the snap position, the pushing blocks 52 are respectively pressed against the block segments of the jaw portions 42 422, so the card segments 422 are partially inserted into the communication pipe 3, and the opposite clamps can be used to fix the correspondingly inserted pipe members. Further, the thrust ribs 53 are biased downward to abut the same. Paired against the top end of the ramp 430. When the pipe fitting inserted in the joint body 3 is to be pulled out, or the pipe fitting is to be inserted and fixed in the joint body 3, the outer casing 5' can be pushed down relative to the joint body 3 to make the outer casing 5 The pusher block 52 is moved downwardly away from the clip segment 422 of the clamping portion 42 such that the swing arm segment 421 of the clamping jaw portion 42 is controlled to elastically swing back outward, respectively, and the card segment is respectively moved out of the communication pipe 30. At the same time, the urging ribs 531 of the urging units 53 respectively corresponding to the slanting slopes and downward movements of the resetting arm portions 43, respectively, and forcing the pair of returning elastic arm portions 43 to gradually become elastically biased (four), respectively, so that The pair of reset spring arms 43 accumulate the reset spring force of the pendulum reset, and at this time, the outer sleeve 5 has been moved downward relative to the spring claws 4 to the release position. When the pipe member has been pulled out or has been inserted, the outer casing 5 can be loosened. At this time, the pair of complex (four) arms 43 will be reset by the elastic spring, forcing the thrust ribs 53 to gradually follow the The abutting surface is moved up, and the pipe body is oscillated to move the pushing blocks 52 upwardly to the latching position, so that the pushing claws 52 are forced to abut the card segments of the claw portions 42. The outer side surface 'forces the card segments 422 to penetrate again into the communication conduit % _ and is snap-fitted onto the tubular member. The resetting elastic arm portion 43 passing through the spring claws 4 has a structural design for the inclined abutting inclined surface 43G against which the urging ribs 201125234 531 abut, so that when the outer sleeve 5 is displaced to the loose position, The elastic force of the outer sleeve is generated, and the 43 is a long rod shape, and the structure is relatively simple, and the outer diameter of the restored elastic arm portion 43 can be adjusted to achieve the adjustment by simple mold construction: The purpose of the resetting elastics 43 is to be elastic. Referring to Figure 6, the second preferred embodiment and the first embodiment of the quick coupler of the present invention consist only in the design of the opposing thrust members 53 and the pair of reset spring arms. For convenience of explanation, only the differences between the present embodiment and the first embodiment will be described below. In the present embodiment, the slanting inclined surfaces 430 of the two reset spring arms 43 are in the shape of a gap, and are gradually extended upward from the positioning ring portion 51. The abutting ribs 531 of the thrust pushing units 53 are opposed to the opposite opposing inclined faces 430 of the pair of resetting elastic arm portions 43, respectively. When the outer sleeve 5 is displaced downward to the loose position, the resisting ribs 531 force the pair of reset spring arms 43 to be elastically biased outwardly, and the reset elastic force is accumulated to make the reset arms The portion 43 can be used to reset the outer sleeve 5 to the buckle position after the user releases the outer sleeve 5. In the present embodiment, each of the urging units 53 has two urging ribs 531. However, in the embodiment, only a single urging rib 531 may be provided, and the urging ribs 53 may be simultaneously pressed down to the pair. Resetting the slanting weight of the spring arm portion 43 can also achieve the purpose of forcing the resilient spring arms 43 to be elastically yawed. - In summary, the straight 201125234 rod-like structure design of the elastic arm portion 43 of the elastic claw 4 is such that when the spring claw 4 is manufactured, the mold structure to be opened is relatively simple, and the mold is easily modified. The structure size method corresponds to the size of the modified rod-shaped complex (four) arm portion 43, so that it is convenient to adjust the elasticity of the reset elastic arm portion 43 of the manufactured elastic claw 4 according to different use requirements, so that the manufacture of the quick joint can be further improved. It is quite convenient and practical for convenience. In addition, by designing the design of the reset spring arm portion 43 in a straight rod shape, it is possible to overcome the problem that the turning point of the top of the inverted V-shaped projectile is easy to stress the set of rubles, and it is easy to cause elastic fatigue. Can increase the service life of the quick connector relatively. Therefore, the object of the present invention can be achieved.
