[0023] It should be noted that the pipe connector can be unlocked by pressing down the unlocking piece 6, so that the unlocking piece 6 can move in the axial direction of the pipe connector. When the unlocking piece 6 slides to the side of the claw ring 7, the end of the unlocking piece 6 will press the claws in the claw ring 7, so that the claws in the claw ring 7 are opened outward. After the claws in the claw ring 7 are opened outward, the pipe at the middle of the claw ring 7 is not fixedly connected with the pipe connector, and the operator can pull out the pipe in the pipe connector. When installing the pipe into the pipe connector, the unlocking piece 6 can also be pressed down to the claws in the claw ring 7. When the claws in the claw ring 7 are opened outward, it will not affect the insertion of the pipe into the quick connection port 11. After the pipe is inserted into the quick connection port 11, the unlocking piece 6 is moved in the opposite direction, so that the unlocking piece 6 no longer presses the claws in the claw ring 7. The claws in the claw ring 7 are gathered to the center of the claw ring 7 and tightly bite on the outer wall of the pipe, so as to fix the pipe inserted into the pipe connector, realize the quick assembly and disassembly of the pipe in the pipe connector, and the operation is convenient. Moreover, the inner ring cover 4 and the outer ring cover 5 at the side of the quick connection port 11 are wrapped by the connecting cylinder 3. The connecting cylinder 3 enhances the connection tightness between the components at the quick connection port 11, so that the pipe connector has excellent high-pressure resistance. In addition, when the claw ring 7 is not under pressure or under low pressure, the end of the unlocking piece 6 is not in contact with the claw ring 7 without human operation, so as not to affect the flexible rotation of the claw ring 7. The end of the unlocking piece 6 abuts on the claws in the claw ring 7 to affect the rotation of the claw ring 7, and avoids the damage of the claws in the claw ring 7 to the surface of the pipe. When the claw ring 7 is under high pressure, the claws of the claw ring 7 will approach the end of the unlocking ring 6 until they contact. At this time, the end of the unlocking piece 6 supports the claws of the claw ring 7, which can improve the pipe locking capacity of the claw ring 7 under high pressure.

[0024] It should be further pointed out that, as shown in Figure 2 , Figure 5 and Figure 6 Combination and shown, the end of the unlocking piece 6 close to the end wall of the quick connection port 11 side is a slope 61, the angle between the slope 61 and the center axis of the outer shell 1 is ∠1, the angle between the claws in the claw ring 7 in the initial state and the center axis of the outer shell 1 is ∠2, the angle of ∠1 is smaller than the angle of ∠2, and the middle of the outer ring cover 5 is provided with a first limiting end face 51. The end wall surface of the unlocking piece 6 outside the slope 61 is a second limiting end face 62.

[0025] The angle of ∠1 is smaller than the angle of ∠2, so that when the end of the unlocking piece 6 is extruded into the pawl in the pawl ring 7, the inclined surface 61 and the inner surface of the pawl in the pawl ring 7 are in tangential relative movement, so as to avoid damage to the surface of the pawl in the pawl ring 7 caused by the end of the unlocking piece 6, thereby affecting the fixing effect of the pawl in the pawl ring 7 on the pipeline; when the unlocking piece 6 moves away from the pawl ring 7, the second limiting end surface 62 and the first limiting end surface 51 abut to limit the unlocking piece 6, so as to avoid overstroke of the unlocking piece 6 when moving away from the pawl ring 7, thereby preventing the unlocking piece 6 from being separated from the pipeline connector.

[0026] Specifically, as Figure 6 As shown in combination, the unlocking piece 6 is provided with a plurality of strip-shaped openings 63 on the side wall close to the inclined surface 61.

[0028] It should be further pointed out that, as Figure 4 and Figure 5 As shown in combination, the unlocking piece 6 is provided with a plurality of strip-shaped openings 63 on the side wall close to the inclined surface 61.

[0029] The unlocking piece 6 is limited by the abutment of the convex edge 64 and the end surface of the outer ring cover 5 away from the quick connection port 11 when moving towards the pawl ring 7, so as to avoid overstroke of the unlocking piece 6 when moving towards the pawl ring 7, thereby preventing the unlocking piece 6 from being excessively inserted into the pipeline connector and being unable to be removed from the pipeline connector.

[0030] It should be further pointed out that, as Figure 3 and Figure 4As shown, the end of the quick connection port 11 is circumferentially provided with a plurality of first insertion openings 13, the inner ring cover 4 is fitted at the end of the quick connection port 11, one end of the inner ring cover 4 is circumferentially provided with a plurality of first insertion blocks 41, the inner ring cover 4 is connected to the outer shell 1 through the cooperation of the first insertion blocks 41 and the first insertion openings 13, the end of the outer ring cover 5 away from the cooperation side of the unlocking member 6 is circumferentially provided with a plurality of second insertion blocks 52, the other end of the inner ring cover 4 is circumferentially provided with a plurality of second insertion openings 42, the outer ring cover 5 is connected to the end of the inner ring cover 4 through the cooperation of the second insertion blocks 52 and the second insertion openings 42, the end of the outer ring cover 5 close to the inner ring cover 4 is internally provided with a cooperation groove 53, the claw ring 7 is fitted in the cooperation groove 53, and the end of the inner ring cover 4 close to the outer ring cover 5 extends into the cooperation groove 53.

[0031] When the pipe connector is assembled, the inner ring cover 4 is connected to the outer shell 1 through the cooperation of the first insertion blocks 41 and the first insertion openings 13, then the unlocking ring and the claw ring 7 are sequentially installed to the outer ring cover 5, and then the outer ring cover 5 is installed to the end of the inner ring cover 4 in the direction of cooperation of the second insertion blocks 52 and the second insertion openings 42, so that the components in the connecting cylinder 3 form an integral whole, not only the outer shell 1, the inner ring cover 4 and the outer ring cover 5 are tightly connected, but also the positions of the claw ring 7 and the unlocking ring in the outer ring cover 5 are maintained and cannot be loosened, after the outer ring cover 5 is assembled, the connection is tightly maintained, so that when the connecting cylinder 3 is assembled to the end of the pipe connector, the position deviation of the connecting cylinder 3 is avoided, the assembly difficulty of the pipe connector is reduced, the errors of the assembly personnel during the assembly of the pipe connector are reduced, and the assembly efficiency of the pipe connector is improved.

[0032] It needs to be further explained that, as shown in the drawings, Figure 2 , Figure 3 and Figure 7 As shown, the connecting cylinder is made of metal, both ends of the connecting cylinder 3 in the axial direction are the closing portions 31, the outer wall surfaces of both ends of the outer shell 1 in the axial direction are provided with the first connecting portions 14, the outer wall of the outer ring cover 5 is provided with the second connecting portion 54, the cross-sectional shapes of the first connecting portions 14 and the second connecting portion 54 are both corrugated with two wave crests, the closing portions 31 are cooperated with the positions of the first connecting portions 14 and the second connecting portion 54 in the wave crests in the cross section respectively, so as to realize the connection of the connecting cylinder 3, the outer shell 1 and the outer ring cover 5.

[0033] The close end 31 of the connecting cylinder 3 is engaged with the first connecting part 14 in the shell 1 and the second connecting part 54 in the outer ring cover 5 when the pipe connector is installed, and the force direction generated by the pipe inserted into the pipe connector to the components connected at both ends of the shell 1 is the axial direction of the connecting cylinder 3. The connecting cylinder 3 is designed with metal material, which can resist the force in the axial direction of the connecting cylinder 3 by the excellent tensile deformation resistance of the metal material when the connecting cylinder 3 bears the force, thereby maintaining the position of the connecting cylinder 3 and the inner ring cover 4, the claw ring 7 and the outer ring cover 5 at both ends of the shell 1, improving the combination firmness of each component arranged at both ends of the pipe connector in the axial direction, and improving the pressure bearing capacity of the overall structure of the pipe connector and the weather resistance of the pipe connector.

[0034] It should be further noted that, as shown in Figure 8 The claw ring 7 is a closed ring body.

[0035] The claw ring 7 is designed in a closed ring shape, so that after the claw is engaged with the pipe surface, the claw ring 7 can bear the force of the pipe in the whole body by the closed structure, and compared with the non-closed ring structure, the claw ring 7 will not deform and cannot fix the pipe in the pipe connector due to uneven force at a position and the gap in the radial direction.
