[0036] Example 1

[0037] See also Figure 1-Figure 3 In this embodiment, the quick-connect nozzle includes a nozzle body 10, which has a connecting end 11 connected to the pipe fitting, a connecting tube 20 is inserted into the interior of the connecting end 11, a sealing ring 30 is provided at the inner end of the connecting tube 20, a stop ring 21 is provided inside the connecting tube 20, and the inner periphery of the stop ring 21 has a plurality of elastic blocking sheets 211 whose outer ends are inclined toward the sealing ring 30, an adjusting tube 40 is slidably clamped in the connecting tube 20 outside the stop ring 21, and the inward movement of the adjusting tube 40 can push down the blocking sheet 211.

[0038] This embodiment utilizes a sealing ring 30 to improve the sealing effect between the pipe fitting and the connecting end 11, and utilizes a stop ring 21 to prevent the pipe fitting and the connecting end 11 that are plugged into each other from unexpectedly disengaging during operation. The blocking sheet 211 can be pushed down by pushing the adjusting cylinder 40 inward, thereby releasing the restriction on the pipe fitting, allowing the pipe fitting to be disengaged from the connecting end 11, thereby achieving the purpose of completing the rapid sealing connection between the nozzle and the pipe fitting by plugging in, and has the advantage of easy operation.

[0039] It should be noted that a step for blocking the sealing ring 30 is provided inside the connection end 11; the sealing ring 30 is entirely restricted inside the connection end 11 by the connection tube 20, and the sealing ring 30 and the connection end 11 are arranged coaxially. As an example, the sealing ring 30 is made of rubber. Along the axial direction of the connection end 11, the inner diameter of the sealing ring 30 decreases from the outside to the inside, and the inner diameter of the smaller end of the sealing ring 30 is smaller than the outer diameter of the corresponding pipe fitting. When the pipe fitting passes through the sealing ring 30 and is inserted into the connection end 11, the sealing ring 30 will be deformed due to the extrusion of the pipe fitting, so that it is tightly wrapped around the outside of the pipe fitting to achieve sealing of the pipe fitting; an annular second clamping ring 31 is integrally formed on the outer wall of the sealing ring 30, and the second clamping ring 31 is arranged coaxially with the sealing ring 30, and the second clamping ring 31 is sealedly clamped inside the second clamping groove 112 on the inner wall of the connection end 11, so that a sealed connection is formed between the sealing ring 30 as a whole and the connection end 11.

[0040] In addition, the connecting tube 20 is arranged coaxially with the connecting end 11 as a whole, and the inner end surface of the connecting tube 20 abuts against the outer end surface of the sealing ring 30, and the inner end surface of the sealing ring 30 abuts against the aforementioned step, thereby limiting the sealing ring 30 inside the connecting end 11, and a first clamping ring 23 is provided on the outer peripheral surface of the connecting tube 20 to be clamped with the first clamping groove 111 on the inner wall of the connecting end 11, and the first clamping ring 23 is constructed into a ring shape coaxially arranged with the connecting tube 20. By utilizing the clamping cooperation between the first clamping ring 23 and the first clamping groove 111, the connecting tube 20 can be locked on the connecting end 11 as a whole, and a limiting groove 22 for clamping the stop ring 21 is provided on the inner wall of the connecting tube 20, and the limiting groove 22 is It is constructed in a ring shape coaxially arranged with the connecting tube 20, and the backstop ring 21 is constructed as a ring sheet as a whole. The blocking sheet 211 and the backstop ring 21 are an integrally formed structure, and the blocking sheet 211 is evenly distributed along the inner circumference of the backstop ring 21, and a groove 212 is opened on the blocking sheet 211. The outer end of the blocking sheet 211 is tilted toward the side where the sealing ring 30 is located. As an example, the backstop ring 21 is made of metal as a whole and has elasticity, that is, the blocking sheet 211 can swing toward the side where the sealing ring 30 is located after being squeezed by the inner end of the adjusting tube 40, and when the blocking sheet 211 loses the squeezing of the inner end of the adjusting tube 40, the blocking sheet 211 can automatically return to its initial state.

[0041] In addition, the adjusting cylinder 40 is coaxially inserted into the connecting cylinder 20 as a whole, and a third clamping ring 41 is provided on the outer periphery of the adjusting cylinder 40 to be clamped with the clamping platform 24 on the inner wall of the connecting cylinder 20, and the third clamping ring 41 is constructed into a ring shape coaxially arranged with the connecting cylinder 20, and the clamping platform 24 is arranged on the outer side of the thrust ring 21. By utilizing the blocking effect of the clamping platform 24, the adjusting cylinder 40 can be prevented from unexpectedly detaching from the connecting cylinder 20 during operation, and the third clamping ring 41 can follow the adjusting cylinder 40 to move in the space inside the clamping platform 24, that is, by pushing the adjusting cylinder 40 inward, the blocking sheet 211 can be pushed toward the side where the sealing ring 30 is located.

[0042] During use, when connecting pipes, the corresponding pipes can be directly inserted into the connecting end 11 through the adjusting cylinder 40. During the insertion process, the blocking piece 211 will be tilted toward the sealing ring 30 side under the squeezing of the pipe until the pipe passes through the blocking piece 211 smoothly and achieves a sealed connection with the sealing ring 30. When the pipe is inserted into place, the outer end of the blocking piece 211 will be clamped on the pipe groove on the outer wall of the pipe, which can prevent the pipe from being unexpectedly separated from the connecting end 11 during operation. When disassembling the pipe, push the adjusting cylinder 40 inward until the blocking piece 211 is separated from the pipe under the drag of the adjusting cylinder 40. After losing the restriction of the blocking piece 211, the pipe can be directly pulled out from the inside of the connecting end 11.

[0043] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
