[0034] Embodiment 1

[0035] An embodiment of the present application discloses a quick connector, which is characterized by comprising a connector body 100; at least one end inside the connector body 100 is provided with a quick connection assembly 200; wherein, the quick connection assembly 200 includes a circlip assembly 210 and a pressing ring 220 arranged in sequence from the inner side to the outer side of the connector body 100 (which can be understood as from inside the pipe to outside the pipe); the circlip assembly 210 includes a spring piece 211, and the spring piece 211 extends towards the axis of the pressing ring 220 and extends out of the inner ring of the pressing ring 220; the pressing ring 220 is adapted to move along the axis direction of the connector body 100 to push against the spring piece 211 for expansion and contraction.

[0036] In this embodiment, the connector 100 serves as the installation main body and is used to connect and communicate multiple pipes to ensure the flow of liquid inside it; at least one end of the connector 100 is provided with a quick-connect component 200, and the quick-connect component 200 is used for quick installation and quick disassembly of pipes; it should be understood that at least one end can be one end, two ends, three ends or even more; for example, when the connector 100 is a single tubular shape, the connector 100 has two ends, and at this time, one end or both ends of the connector 100 can be provided with the quick-connect component 200 for accessing pipes; when the connector 100 is a three-way pipe, one end, two ends or three ends of the connector 100 can be provided with the quick-connect component 200 according to actual needs for connecting the pipes to be used; and so on, the number of ends of the connector 100 and the number of corresponding quick-connect components 200 are not limited; further, the quick-connect component 200 includes a snap ring component 210 and a pressing ring 220 arranged in sequence from the inside to the outside of the connector 100 (which can be understood as from inside the pipe to outside the pipe); the snap ring component 210 is used to clamp the water pipe to be connected; the pressing ring 220 can be used to unlock the clamping state of the snap ring component 210 on the water pipe; specifically, the snap ring component 210 includes a spring piece 211, and the spring piece 211 extends towards the axis of the pressing ring 220 and extends out of the inner ring of the pressing ring 220. The spring piece 211 is arranged to extend out of the inner ring of the pressing ring 220 so as to facilitate clamping the water pipe to be connected by the spring piece 211, and it will not cause the spring piece 211 to be unable to clamp the water pipe to be connected because the pressing ring 220 blocks the spring piece 211; further, the pressing ring 220 is adapted to move along the axis direction of the connector 100 to push the spring piece 211 to expand and contract; for easy understanding, the following is an example: when a water pipe needs to be accessed, the pressing ring 220 does not push the spring piece 211, and at this time, the spring piece 211 is in an extended state. The water pipe is passed through the pressing ring 220 and the snap ring component 210; the spring piece 211 in the snap ring component 210 is compressed by the water pipe to generate displacement. Since the spring piece 211 has elasticity, the spring piece 211 will clamp the water pipe tightly under its own reset force, thereby realizing the quick connection of the water pipe and the embodiment of the present application; when the water pipe needs to be pulled out from the connector 100, the pressing ring 220 is pressed to push the spring piece 211 to compress it again, so that the spring piece 211 is separated from the water pipe, that is, the clamping state of the spring piece 211 on the water pipe is released, and at this time, the water pipe can be freely pulled out, thereby realizing the quick disassembly of the water pipe; thus, through the simple structure of the embodiment of the present application, stable connection and quick plugging and unplugging of the water pipe can be realized, with low manufacturing cost, simple operation and high practicability, and it is suitable for popularization and use.

[0037] In an alternative embodiment, the spring piece 211 has a first inclined surface 2111 extending towards the end away from the pressing ring 220; one end of the pressing ring 220 facing the spring piece 211 is provided with a second inclined surface to move to push the spring piece 211 to expand and contract.

[0038] In this embodiment, by providing a first inclined surface 2111 on the elastic piece 211 (it can also be understood that the entire elastic piece 211 is in an inclined state), and providing a second inclined surface on the pressing ring 220, when it is necessary to pull out the water pipe for use, for example, by pushing the pressing ring 220 to drive the second inclined surface to abut against the first inclined surface 2111, the elastic piece 211 can be contracted, making the entire pushing process more labor-saving and smooth. And by setting the elastic piece 211 in an inclined state, it is more conducive to the reset of the elastic piece 211 itself after contraction, can extend the service life of the elastic piece 211, and is not easily damaged.

[0039] In an alternative embodiment, a plurality of first inclined surfaces 2111 form a conical surface; one end of the pressing ring 220 facing the first inclined surface 2111 is provided as a conical sleeve 221, and the conical sleeve 221 has a second inclined surface.

[0040] In this embodiment, a plurality of first inclined surfaces 2111 form a conical surface, that is, the elastic pieces 211 are provided in a plurality and are annularly distributed, so that a plurality of first inclined surfaces 2111 jointly form a conical surface, and one end of the pressing ring 220 facing the first inclined surface 2111 is provided as a conical sleeve 221, and the outer side surface of the conical sleeve 221 is also a conical surface; through the cooperation of the two conical surfaces, the action of the pressing ring 220 abutting against the snap ring assembly 210 is more stable.

[0041] In an alternative embodiment, the snap ring assembly 210 further includes a spring coil 212 and a snap sleeve 213: the snap sleeve 213 is installed in the connecting body 100; the spring coil 212 is clamped on the snap sleeve 213; a plurality of elastic pieces 211 are evenly distributed on the spring coil 212.

[0042] In this embodiment, the snap sleeve 213 is installed in the connecting body 100 to clamp the spring coil 212; to prevent the snap sleeve 213 from moving during use and causing unstable connection with the water pipe, a limiting structure can be provided in the connecting body 100 to at least limit the displacement of the snap sleeve 213 along the axis direction of the connecting body 100, and the radial movement or rotation of the snap sleeve 213 can also be selectively limited; the setting of the spring coil 212 enables the elastic pieces 211 to be annularly distributed along the spring coil 212, which is beneficial to the uniform force of the snap ring assembly 210 when being abutted, and the annular spring coil 212 is suitable for most pipe body shapes; preferably, the spring coil 212 and the elastic pieces 211 are made of metal material and / or the snap sleeve 213 is made of metal material, which can effectively improve its service life and use stability; further, the metal material can be at least one metal material with certain rust prevention performance such as stainless steel, zinc alloy, titanium alloy, etc.

[0043] In an alternative embodiment, a first hook surface 2211 is formed at the large end of the tapered sleeve 221; the inner wall of the connecting body 100 or the inner wall of the fixing portion of the snap ring assembly 210 (the inner wall of the fixing portion can be the inner wall of the ferrule 213 as described above) has a second hook surface 110; the second hook surface 110 is adapted to abut and limit the first hook surface 2211 along the axial direction of the connecting body 100.

[0044] In this embodiment, since the first hook surface 2211 is formed by the large end of the tapered sleeve 221 itself, there is no need to design an additional hook surface structure. It only needs to make the large end of the tapered sleeve 221 extend beyond the main body of the pressing ring 220 by a certain length, so that the overall structure of the pressing ring 220 is relatively simple and compact; and the inner wall of the connecting body 100 or the inner wall of the fixing portion of the snap ring assembly 210 (the inner wall of the fixing portion can be the inner wall of the ferrule 213 as described above) has a second hook surface 110. As for whether the second hook surface 110 is specifically provided on the inner wall of the connecting body 100 or the inner wall of the ferrule 213, it can be set according to specific circumstances; during use, the pressing ring 220 moves along the axial direction of the connecting body 100. Pushing inwardly into the connecting body 100 compresses the elastic piece 211; pushing outwardly releases the compression of the elastic piece 211; to prevent the pressing ring 220 from directly disengaging from the connecting body 100, the second hook surface 110 can block the first hook surface 2211 when the pressing ring 220 moves outward.

[0045] In an alternative embodiment, the pressing ring 220 further includes an annular flange 222. The annular flange 222 is located at the end of the pressing ring 220 away from the snap ring assembly 210, and there is a gap between the annular flange 222 and the connecting body 100.

[0046] In this embodiment, the setting of the annular flange 222 facilitates the lifting and pushing actions of the pressing ring 220, and ensuring that there is a gap between the annular flange 222 and the connecting body 100 can cooperate with the moving stroke of the pressing ring 220 to avoid interference.

[0047] In an alternative embodiment, the quick-connecting assembly 200 further includes a sealing ring 230; the sealing ring 230 is disposed on the side of the snap ring assembly 210 away from the pressing ring 220; the setting of the sealing ring 230 can seal the connection between the ferrule 213 in the snap ring assembly 210 and the connecting body 100 to ensure the orderly flow of the liquid in the pipeline.
