As shown in fig. 1 to 3, an embodiment of the present invention discloses a quick coupling, which includes a first coupling body 10 and a second coupling body 20, wherein the first coupling body 10 and the second coupling body 20 are connected by plugging.
The first joint body 10 includes a first main body part 11 and a first pipe part 12 which are integrally formed, the first main body part 11 being coaxial with the first pipe part 12; a plurality of annular inverted teeth are formed on the periphery of the first pipe part 12, the air pipe is sleeved on the first pipe part 12, and the air pipe is prevented from being separated from the first pipe part 12 through the annular inverted teeth.
The outer diameter of the first body portion 11 is larger than the first tube portion 12, so that the first body portion 11 has a radially expanded structural feature, a circular slot 111 is formed in the first body portion 11, and the insertion tube 13 extends axially outward from the bottom of the circular slot 111.
The second joint body 20 includes a second main body portion 21 and a second pipe portion 22 which are integrally formed, the second main body portion 21 being coaxial with the second pipe portion 22; a plurality of annular inverted teeth are formed on the periphery of the second pipe part 22, the air pipe is sleeved on the second pipe part 22, and the air pipe is prevented from being separated from the second pipe part 22 through the annular inverted teeth.
The outer diameter of the second body portion 21 is larger than that of the second pipe portion 22, so that the second body portion 21 has a structural feature of radial expansion, and a stepped portion 211 is formed in a region between the second body portion 21 and the second pipe portion 22; further, an insertion hole 23 that engages with the insert tube 13 of the first joint body 10 is formed extending axially inward from the end surface of the second body portion 21, and a seal ring 231 is further installed in the insertion hole 23.
In use, the second connector body 20 is coaxially aligned with the first connector body 10 such that the second body portion 21 faces and approaches the first body portion 11, the insertion tube 13 on the first body portion 11 is then inserted into the insertion hole 23 of the second body portion 21, and then the second body portion 21 is extended into the circular insertion groove 111 of the first body portion 11.
In the present invention, at least one anti-slip bayonet pin 30 is further pivoted on the outer circumferential surface of the first main body 11, and specifically, the anti-slip bayonet pin 30 includes a rod 31 and a hook 32 which are integrally formed, the hook 32 is located at the front end of the rod 31 and forms an L-shaped structure with the rod 31, a notch 112 having two vertical walls is formed on the outer circumference of the first main body 11, the middle of the rod 31 is located between the two vertical walls, the tail of the rod 31 extends out of the notch 112, and a pin 33 is disposed in the notch 112, the pin 33 is transversely disposed between the two vertical walls to pass through the rod 31, so that the anti-slip bayonet pin 30 can pivot, and the end of the hook 32 of the anti-slip bayonet pin 30 abuts against the step 211 of the second main body 21 by counterclockwise pivoting, and the hook 32 of the anti-slip bayonet pin 30 can escape from the step 211 of the second main body 21 by clockwise pivoting. An annular groove 113 is formed on the outer periphery of the first main body 11, the annular groove 113 passes through the front portion of the rod 31 of the anti-falling bayonet pin 30, and is sleeved on the annular groove 113 by an elastic rubber band 40, the elastic rubber band 40 applies elasticity to the front portion of the rod 31 to enable the hook portion 32 of the anti-falling bayonet pin 30 to abut against the step portion 211 of the second main body 21, as shown in fig. 1, so as to prevent the second joint body 20 from being separated from the first joint body 10, and enable the second joint body 20 to be kept in a butt joint state with the first joint body 10. When the second connector body 20 and the first connector body 10 need to be disassembled, a finger applies a radially inward pressure to the tail of the rod 31 of the anti-falling bayonet pin 30 to warp the head of the rod 31, so as to drive the hook portion 32 to be separated from the step portion 211 of the second main body portion 21, and thus, the second connector body 20 can be separated from the first connector body 10 by applying a small axial force to the second connector body 20.
The quick connector provided by the invention has the advantages that:
the anti-falling bayonet lock 30 arranged outside the connector body and the elastic part are matched to control the butt joint and separation of the two connector bodies, the operation is convenient, and if the elastic part fails and is convenient to replace, the situation that the two connector bodies are difficult to plug or separate due to the failure of the internal clamp spring can be avoided.
