Description

Technical Field

[0001] This utility model relates to the field of fluid transport technology, and more specifically, to a connector assembly. Background Technology

[0002] With the widespread application of fluid transport technology in the catering industry, the demand for using pipelines to realize fluid transmission / distribution is increasing, and connectors, as key components for pipeline connection, are becoming more and more important.

[0003] Traditionally, a connector includes a housing, a spring, and a lock cylinder. The housing has a connection port, and the spring is located inside the housing. One end of the spring abuts against the lock cylinder so that the lock cylinder closes the connection port when the spring is in its natural state. The lock cylinder can move to open the connection port when the connector is connected to other connectors, thereby enabling pipeline connection. However, the spring inside the housing comes into contact with the liquid flowing through the housing, and fibers and particles in the liquid can easily remain on the spring. Even after disassembling the housing and lock cylinder, it is still difficult to thoroughly clean them. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a connector assembly is provided, the technical solution of which is as follows.

[0005] The connector assembly includes a mounting connector, a lock cylinder, a lock core, and a first elastic element. The mounting connector has a first cavity; the lock cylinder is connected to one end of the mounting connector; the lock core has a second cavity, and the lock core passes through the lock cylinder and surrounds the lock cylinder to form an isolation cavity that is isolated from the second cavity; the first elastic element is located within the isolation cavity; wherein, the lock cylinder is configured such that: when the first elastic element is in a first state, it is in a first mating state with the lock cylinder, and the second cavity is isolated from the first cavity in the first mating state; when the first elastic element is in a second state, it is in a second mating state with the lock cylinder, and the second cavity is connected to the first cavity in the second mating state.

[0006] The connector assembly of this utility model has a lock cylinder that passes through the lock head and surrounds the lock head to form an isolation cavity that is isolated from the second cavity. A first elastic element is located in the isolation cavity. The lock cylinder is configured such that: when the first elastic element is in a first state, it is in a first engagement state with the lock head, and the second cavity is isolated from the first cavity in the first engagement state; when the first elastic element is in a second state, it is in a second engagement state with the lock head, and the second cavity is connected to the first cavity in the second engagement state. Thus, when applied to fluid transportation, liquid flows through the first cavity and the second cavity. The first elastic element is located in the isolation cavity to separate itself from the liquid, thereby effectively preventing the first elastic element from contacting the liquid and preventing fibers and particles in the liquid from remaining on the first elastic element, thus facilitating cleaning.

[0007] For example, the lock cylinder has a first mating section that slides with the lock head. The first mating section has a connecting hole. When the lock cylinder and lock head are in the first mating state, the first mating section is in a first position, and the connecting hole is sealed inside the lock head, isolating the second cavity from the first cavity. When the lock cylinder and lock head are in the second mating state, the first mating section is in a second position, and the second cavity communicates with the first cavity through the connecting hole. This configuration allows for control of the connection between the first and second cavities with only axial thrust or pull, facilitating operation, simplifying the structure, and saving costs.

[0008] For example, the lock head has a cavity, a first mating section passes through the cavity, and a first sealing element is fitted on the side of the first mating section near the first cavity. When the lock cylinder and the lock head are in the first mating state, the first sealing element blocks the cavity to seal the connecting hole inside the lock head. With this configuration, sealing the cavity with the first sealing element not only effectively ensures the isolation between the first cavity and the second cavity, but also prevents liquid from entering the isolation cavity.

[0009] For example, the cavity protrudes inward with an abutment portion, and the lock cylinder has a second mating section connected to the first mating section. When the lock cylinder and lock head are in the first mating state, the first seal abuts against the abutment portion; when the lock cylinder and lock head are in the second mating state, the second mating section at least partially abuts against the abutment portion. This configuration serves two purposes: firstly, when the lock cylinder and lock head are in the first mating state, the abutment portion between the first seal and the abutment portion prevents the lock cylinder from dislodging from the lock head, and the sealing of the cavity effectively isolates the first and second cavities, while also preventing liquid from entering the isolation cavity; secondly, when the lock cylinder and lock head are in the second mating state, the abutment portion between the second mating section at least partially prevents the lock cylinder from dislodging from the lock head, and the second mating section also prevents liquid from entering the isolation cavity.

[0010] For example, a second sealing element is sandwiched between the second mating section and the lock head. This arrangement, through the sealing effect of the second sealing element, further prevents liquid from entering the isolation chamber, thereby effectively preventing the first elastic element inside the isolation chamber from contacting the liquid, and preventing fibrous and particulate matter in the liquid from remaining on the first elastic element, thus facilitating cleaning.

[0011] For example, the lock head is detachably connected to one end of the mounting connector, and a third seal is sandwiched between the lock head and the mounting connector. This arrangement ensures a tight seal, effectively preventing liquid from leaking out from the connection gap between the lock head and the mounting connector.

[0012] For example, the mounting connector and the lock cylinder are switchable between a locked state and an unlocked state via an anti-rotation structure. In the locked state, the mounting connector and the lock cylinder are locked together; in the unlocked state, the mounting connector and the lock cylinder can be separated. This design prevents the mounting connector from becoming loose due to accidental operation, thereby preventing liquid from leaking between the lock cylinder and the mounting connector.

[0013] For example, the anti-rotation structure includes an anti-rotation ring, a limiting member disposed on the mounting joint, and a locking portion disposed on the lock head. The limiting member has an axial limiting portion and a circumferential limiting portion connected together. The anti-rotation ring is sleeved on the mounting joint and locks against the circumferential limiting portion. The anti-rotation ring is provided with a locking groove. In the locked state, the anti-rotation ring abuts against the axial limiting portion, and the locking portion locks against the locking groove. In the unlocked state, the anti-rotation ring separates from the axial limiting portion, and the locking portion separates from the locking groove. With this configuration, the mounting joint and the lock head can be locked or unlocked by pushing or pulling the anti-rotation ring. This not only facilitates operation but also prevents liquid leakage between the lock head and the mounting joint due to accidental operation causing the mounting joint and the lock head to loosen. Furthermore, the structure is simple and cost-effective.

[0014] For example, the lock head is provided with a sliding blocking part, a second elastic element, and a guide groove. The guide groove has a guide section and a fixed section. The sliding blocking part is movable between a third position and a fourth position via the second elastic element. In the third position, the sliding blocking part covers at least part of the guide section; in the fourth position, the sliding blocking part opens the guide section. This configuration, on the one hand, allows the connector assembly to lock with the components of the docking assembly via the sliding blocking part, the second elastic element, and the guide groove during docking, preventing the connector assembly from detaching from the docking assembly and affecting the stable flow of liquid. On the other hand, by using pushing or pulling force to cover or open the guide section, it prevents the components of the docking assembly from detaching from the guide groove due to misoperation. Furthermore, the structure is simple and cost-effective.

[0015] For example, the lock head is provided with a fixing part. With this configuration, when the connector assembly is mated, the fixing part can lock the components of the mating assembly, preventing the connector assembly from detaching from the mating assembly on its own and affecting the stable flow of liquid.

[0034] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0035] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0036] This invention provides a connector assembly. The connector assembly of this invention can be used in fluid transport. A detailed description of a connector assembly according to an embodiment of this invention will be provided below with reference to the accompanying drawings.

[0037] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 12 and Figure 13 When used in fluid transport, the connector assembly 1 can be connected to a docking assembly, which can be the connector assembly 1 or a pipeline, etc. The connector assembly 1 may include a mounting connector 110, a locking head 120, a locking cylinder 130, and a first elastic member 140. The mounting connector 110 may have a first cavity 111. The locking head 120 may be connected to one end of the mounting connector 110. The locking cylinder 130 may have a second cavity 131, and the locking cylinder 130 may pass through the locking head 120 and enclose it to form an isolation cavity 150 isolated from the second cavity 131. The locking head 120 may have a third cavity 121, and the locking cylinder 130 is at least partially located within the third cavity 121. The first elastic member 140 may be located within the isolation cavity 150. The locking cylinder 130 may be configured as follows: Figure 2 and Figure 7 When the first elastic element 140 is in the first state, it is in a first engaging state with the lock head 120, and the second cavity 131 is isolated from the first cavity 111 in the first engaging state; as Figure 13 When the first elastic element 140 is in the second state, it is in the second engagement state with the lock head 120, and the second cavity 131 is connected to the first cavity 111 in the second engagement state.

[0038] The connector assembly 1 of this utility model has a lock cylinder 130 passing through a lock head 120 and forming an isolation cavity 150 that is isolated from the second cavity 131. A first elastic member 140 is located within the isolation cavity 150. The lock cylinder 130 is configured such that: when the first elastic member 140 is in a first state, it is in a first engagement state with the lock head 120, and the second cavity 131 is isolated from the first cavity 111 in the first engagement state; when the first elastic member 140 is in a second state, it is in a second engagement state with the lock head 120, and the second cavity 131 is connected to the first cavity 111 in the second engagement state. Thus, when applied to fluid transportation, liquid flows through the first cavity 111 and the second cavity 131. The first elastic member 140 is located within the isolation cavity 150 to separate it from the liquid, thereby effectively preventing the first elastic member 140 from contacting the liquid and preventing fibrous and particulate matter in the liquid from remaining on the first elastic member 140, thus facilitating cleaning.

[0039] For example, the first elastic element 140 can be a spring or the like. The first state of the first elastic element 140 can be a relaxed state, and the second state can be a compressed state. Thus, after the connector assembly 1 disconnects from the docking assembly, the first cavity 111 and the second cavity 131 can be automatically isolated by the restoring force of the first elastic element 140, requiring no additional operation and preventing liquid from flowing out of the second cavity 131 due to failure to isolate in time. Of course, the first state of the first elastic element 140 can also be a compressed state, and the second state can also be a relaxed state, to suit various scenarios.

[0040] See also Figure 2 , Figure 7 and Figure 10 The lock cylinder 130 may have a first mating section 132 that slides with the lock head 120. A through hole 1321 may be provided on the first mating section 132. It should be noted that the end of the lock cylinder 130 near the first cavity 111 may be closed. Figure 2 and Figure 7 When the lock cylinder 130 and the lock head 120 are in the first mating state, the first mating section 132 can be in the first position, and the connecting hole 1321 can be sealed inside the lock head 120 to isolate the second cavity 131 from the first cavity 111. That is, the first mating section 132 slides into the third cavity 121 until the connecting hole 1321 is sealed inside the third cavity 121, thereby isolating the second cavity 131 from the first cavity 111. Figure 13 When the lock cylinder 130 and lock head 120 are in the second mating state, the first mating section 132 is in the second position, and the second cavity 131 is connected to the first cavity 111 through the connecting hole 1321. That is, the first mating section 132 slides into the first cavity 111 until the connecting hole 1321 is located within the first cavity 111, thereby connecting the second cavity 131 with the first cavity 111. Thus, only axial pushing or pulling force is needed to control the connection and disconnection between the first cavity 111 and the second cavity 131, which is convenient to operate, has a simple structure, and saves costs.

[0041] See also Figure 2 , Figure 4 , Figure 7 and Figure 10The lock cylinder 120 may have a cavity 122, which is located close to the first cavity 111. A first mating section 132 may pass through the cavity 122, and a first sealing element 134 may be fitted onto the side of the first mating section 132 near the first cavity 111. Specifically, a groove may be provided on the side of the first mating section 132 near the first cavity 111, and the first sealing element 134 may be a sealing ring, which may be fitted onto the lock cylinder 120 within the groove. The sealing ring may be made of rubber or silicone, etc. When the lock cylinder 130 and the lock cylinder 120 are in the first mating state, the first sealing element 134 may seal the cavity 122 to seal the connecting hole 1321 within the lock cylinder 120. Thus, by sealing the cavity 122 with the first sealing element 134, not only can the isolation between the first cavity 111 and the second cavity 131 be effectively ensured, but liquid can also be prevented from entering the isolation cavity 150.

[0042] See also Figure 2 , Figure 4 , Figure 7 , Figure 10 and Figure 13 The cavity 122 may have an inwardly protruding abutment portion 1221. The lock cylinder 130 may have a second mating section 133. The second mating section 133 may be connected to the first mating section 132. When the lock cylinder 130 and the lock head 120 are in the first mating state, the first seal 134 may abut against the abutment portion 1221. When the lock cylinder 130 and the lock head 120 are in the second mating state, the second mating section 133 may at least partially abut against the abutment portion 1221. Thus, on the one hand, when the lock cylinder 130 and the lock head 120 are in the first mating state, the first sealing member 134 abuts against the abutment portion 1221, preventing the lock cylinder 130 from coming out of the lock head 120. Furthermore, by sealing the cavity hole 122 with the first sealing member 134, the first cavity 111 and the second cavity 131 can be effectively isolated, while also preventing liquid from entering the isolation cavity 150. On the other hand, when the lock cylinder 130 and the lock head 120 are in the second mating state, the second mating section 133 at least partially abuts against the abutment portion 1221, preventing the lock cylinder 130 from coming out of the lock head 120. Moreover, the second mating section 133 can prevent liquid from entering the isolation cavity 150.

[0043] See also Figure 2 and Figure 7A second sealing element 161 can be sandwiched between the second mating section 133 and the lock head 120. Specifically, a groove can be provided on the second mating section 133, and the second sealing element 161 can be a sealing ring, which can be fitted into the groove. Of course, the sealing ring can also have other settings, such as being set in a groove on the lock head 120. The sealing ring can be made of rubber or silicone, etc. In this way, through the sealing effect of the second sealing element 161, liquid is further prevented from entering the isolation chamber 150, thereby effectively preventing the first elastic element 140 in the isolation chamber 150 from contacting the liquid, and preventing fibers and particles in the liquid from remaining on the first elastic element 140, thus facilitating cleaning.

[0044] See again Figure 2 and Figure 7 The lock head 120 may have a connecting wall 123, an inner ring wall 124, and an outer ring wall 125. The connecting wall 123 connects the inner ring wall 124 and the outer ring wall 125. The outer wall surface of the second mating section 133 may have a boss 1331 protruding from it in the direction away from the second cavity 131. The outer wall surface of the second mating section 133 may slide against the inner ring wall 124. The outer ring wall 125 may have a first wall segment 1251 and a second wall segment 1252 arranged sequentially along its length. The first wall segment 1251 may be arranged opposite to the inner ring wall 124, and the second wall segment 1252 may slide with the boss 1331 so that the boss 1331 is closer to or further away from the connecting wall 123. The boss 1331, part of the outer wall surface of the second mating section 133, the inner ring wall 124, the connecting wall 123, and the outer ring wall 125 may surround and form an isolation cavity 150, thereby ensuring the sealing of the isolation cavity 150. The first elastic element 140 transitions between a first state and a second state through the pushing or pulling force between the boss 1331 and the connecting wall 123. The first elastic element 140 is radially limited by the inner ring wall 124, the outer ring wall 125, and a portion of the outer wall surface of the second mating section 133. When the lock cylinder 130 and the lock head 120 are in the first mating state, the boss 1331 moves away from the inner ring wall 124. When the lock cylinder 130 and the lock head 120 are in the second mating state, the boss 1331 abuts against the inner ring wall 124. Thus, on the one hand, only axial thrust or pull is needed to control the opening and closing of the first cavity 111 and the second cavity 131, which is convenient to operate and has a simple structure, saving costs; on the other hand, it ensures the sealing of the isolation cavity 150. The first elastic element 140 is located inside the isolation cavity 150 to separate it from the liquid, thereby effectively preventing the first elastic element 140 from contacting the liquid and preventing fiber and particulate matter in the liquid from remaining on the first elastic element 140, thus facilitating cleaning.

[0045] For example, when the first elastic member 140 is in a natural state in the first state and a compressed state in the second state: when the connector assembly 1 docks with the docking assembly, the lock cylinder 130 is pushed by the docking assembly, causing the first elastic member 140 to be in a compressed state. The lock cylinder 130 and the lock head 120 are in a second mating state. The boss 1331 moves close to the connecting wall 123 until it abuts against the inner ring wall 124. The second mating section 133 abuts against the abutting part 1221. The first sealing member 134 moves away from the abutting part 1221. The connecting hole 1321 is located in the first cavity 111, so that the first cavity 111 and the second cavity 131 are connected through the connecting hole 1321. The second sealing member 161 is always located between the inner ring wall 124 and the outer wall surface of the second mating section 133. When the connector assembly 1 is disconnected from the docking assembly, the thrust applied to the lock cylinder 130 is released, the first elastic element 140 returns to its natural state, and the first elastic element 140 drives the lock cylinder 130 and the lock head 120 to be in the first mating state. The boss 1331 moves away from the connecting wall 123, the second mating section 133 moves away from the abutment part 1221, the first sealing element 134 abuts against the abutment part 1221, the connecting hole 1321 is located in the third cavity 121, the first sealing element 134 blocks the cavity hole 122 to isolate the first cavity 111 from the second cavity 131, and the second sealing element 161 is always located between the inner ring wall 124 and the outer wall surface of the second mating section 133. Thus, on the one hand, only axial thrust is needed to control the connection between the first cavity 111 and the second cavity 131. After the connector assembly 1 is disconnected from the docking assembly, the restoring force of the first elastic element 140 can automatically drive the first sealing element 134 to seal the cavity hole 122, thereby isolating the first cavity 111 from the second cavity 131. No additional operation is required, and the phenomenon of liquid flowing out of the second cavity 131 due to failure to isolate in time is avoided. On the other hand, the second sealing element 161 ensures the sealing of the isolation cavity 150. The first elastic element 140 is located inside the isolation cavity 150 to separate it from the liquid, thereby effectively preventing the first elastic element 140 from contacting the liquid and preventing fiber and particulate matter in the liquid from remaining on the first elastic element 140, thus facilitating cleaning.

[0046] For example, the isolation cavity 150 can be formed in various forms besides being enclosed by the structure described above. For instance, taking the lock cylinder 130 and the same structure as described above, the lock head 120 can have a first cavity 111 segment for closing the connecting hole 1321 and a second cavity 131 segment for closing the first elastic member 140. Two sealing rings are spaced apart between the second cavity 131 segment and the second mating segment 133. The second mating segment 133, the second cavity 131 segment, and the two sealing rings enclose the isolation cavity 150, and the first elastic member 140 switches between a first state and a second state depending on the pushing or pulling force of the sealing rings on the second mating segment 133. Thus, while ensuring the sealing performance of the isolation cavity 150, it can be applied to various scenarios.

[0047] See also Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The lock head 120 is detachably connected to one end of the mounting connector 110, and a third sealing element 162 can be sandwiched between the lock head 120 and the mounting connector 110. Specifically, the end of the lock head 120 connected to the mounting connector 110 can be provided with a groove, and the third sealing element 162 can be a sealing ring, which can be fitted into the groove. Of course, the sealing ring can also have other settings, such as being set in a groove provided on the mounting connector 110. The sealing ring can be made of rubber or silicone, etc. Specifically, the lock head 120 and the mounting connector 110 can have various connection methods, such as internal and external thread screw connection, screw connection, or snap connection, which facilitates the maintenance, replacement, or cleaning of the lock head 120 or the mounting connector 110. In this way, the sealing performance is ensured, effectively preventing liquid from flowing out from the connection gap between the lock head 120 and the mounting connector 110.

[0048] The installation process is described with the installation connector 110 and the lock head 120 rotated together via internal and external threads: The first elastic element 140 can be sleeved on the outside of the lock cylinder 130. When the lock cylinder 130 passes through the third cavity 121, the first elastic element 140 can enter the third cavity 121 along with the lock cylinder 130 until the first elastic element 140 is located in the isolation cavity 150. The lock cylinder 130 is pushed so that the first mating section 132 at least partially passes through the cavity hole 122, so that the first seal 134 is installed into the groove on the first mating section 132. After the external force is removed, the first seal 134 abuts against the abutment part 1221, and then the installation connector 110 and the lock head 120 are rotated together via internal and external threads, thereby completing the installation of the connector assembly 1.

[0049] When the mounting connector 110 and the lock head 120 are rotatably connected via internal and external threads, although the mounting connector 110 and the lock head 120 are easy to install or remove, it is easy to accidentally rotate the mounting connector 110 or the lock head 120 when disassembling other parts, causing the mounting connector 110 and the lock head 120 to loosen. To solve this problem, combined with... Figures 1 to 5 The mounting connector 110 and the lock cylinder 120 are switchable between a locked state and an unlocked state via an anti-rotation structure 170. In the locked state, the mounting connector 110 and the lock cylinder 120 are locked together; in the unlocked state, the mounting connector 110 and the lock cylinder 120 can be separated. This prevents the mounting connector 110 from becoming loose due to accidental operation, thereby preventing liquid from flowing out between the lock cylinder 120 and the mounting connector 110.

[0050] Combined again Figures 1 to 5 The anti-rotation structure 170 may include an anti-rotation ring 171, a limiting member 172 disposed on the mounting joint 110, and a snap-fit ​​portion 173 disposed on the lock head 120. The limiting member 172 may have an axial limiting portion 1721 and a circumferential limiting portion 1722 connected to each other. The anti-rotation ring 171 may be sleeved on the mounting joint 110 and snap-fitted with the circumferential limiting portion 1722. The anti-rotation ring 171 may be provided with a groove (not shown in the figure), which may be disposed at one end of the anti-rotation ring 171 near the lock head 120. In the locked state, the anti-rotation ring 171 abuts against the axial limiting portion 1721, and the snap-fit ​​portion 173 snaps into the groove; in the unlocked state, the anti-rotation ring 171 is separated from the axial limiting portion 1721, and the snap-fit ​​portion 173 is separated from the groove. Specifically, the inner wall of the anti-rotation ring 171 is recessed to form a sliding groove 1711 that engages with the circumferential limiting portion 1722. The circumferential limiting portion 1722 can be a sliding rib provided on the mounting joint 110. The sliding rib can be located within the sliding groove 1711, thereby restricting the circumferential rotation of the anti-rotation ring 171 relative to the mounting joint 110. The sliding groove 1711 can move axially relative to the sliding rib. A first latch 1712 can be provided within the sliding groove 1711, located at the end of the sliding groove 1711 away from the slot. The axial limiting portion 1721 is configured as a second latch protruding from the sliding rib, located at the end of the sliding rib near the locking head 120. When the slot engages with the engaging portion 173, the first latch 1712 engages with the second latch, thereby restricting the axial movement of the anti-rotation ring 171 relative to the mounting joint 110. A contact platform 112 is provided at the end of the sliding rib away from the second latch to prevent the anti-rotation ring 171 from disengaging from the end of the sliding rib away from the latch. The latching part 173 may have a latching platform 1731 and a latching rib 1732, with the latching rib 1732 disposed on the latching platform 1731. A positioning groove 1713 is formed by a recess on the inner wall of the anti-rotation ring 171 near the latching groove. In the locked state, the latching platform 1731 enters the anti-rotation ring 171 and abuts against the positioning groove 1713, while the latching rib 1732 abuts against the latching groove. Thus, the mounting connector 110 and the lock head 120 can be locked or unlocked by pushing or pulling the anti-rotation ring 171. This not only facilitates operation but also prevents liquid from leaking between the lock head 120 and the mounting connector 110 due to misoperation, while also simplifying the structure and saving costs.

[0051] For example, there can be multiple sliding ribs. Since the second clips are disposed on the sliding ribs, the number of second clips can correspond to the number of sliding ribs. Multiple sliding ribs can be circumferentially spaced on the mounting joint 110, with the second clips disposed on the corresponding sliding ribs. Since the sliding grooves 1711 are used to mate with the sliding ribs, the number of sliding grooves 1711 can correspond to the number of sliding ribs, and they are correspondingly spaced on the anti-rotation ring 171. Since the first clips 1712 are disposed within the sliding grooves 1711, the number of first clips 1712 can correspond to the number of sliding grooves 1711. This ensures uniform circumferential limiting stress distribution, preventing excessive local stress distribution that could damage the sliding ribs, and also ensures uniform axial limiting stress distribution, preventing excessive local stress distribution that could damage the first clips 1712 and / or the second clips. Specifically, there can be four sliding ribs and four sliding grooves 1711. This ensures uniform distribution of circumferential limiting stress, avoids excessive local stress distribution which could damage the sliding ribs, and the fewer ribs make them easier to manufacture. There are also four first clips 1712 and four second clips. This ensures uniform distribution of axial limiting stress, avoids excessive local stress distribution which could damage the first clips 1712 and / or the second clips, and the fewer clips make them easier to manufacture.

[0052] See also Figure 3 and Figure 5 The outer wall of the anti-rotation ring 171 may be provided with a handle 1714 so that the user can hold the anti-rotation ring 171 to perform locking or unlocking operations. The slot may be at least partially provided in the handle 1714, so as to limit the locking rib 1732 through the handle 1714, ensuring uniform stress distribution and avoiding excessive local stress distribution.

[0053] For example, there can be multiple snap-fit ​​ribs 1732, which can be circumferentially spaced on the snap-fit ​​platform 1731. The number of snap-fit ​​slots corresponds to the number of snap-fit ​​ribs 1732. Specifically, there can be two snap-fit ​​ribs 1732. There can also be two snap-fit ​​slots. This ensures uniform stress distribution, avoids excessive local stress distribution that could damage the snap-fit ​​ribs 1732, and the smaller number makes them easier to manufacture.

[0054] See also Figure 1 and see Figure 3The mounting connector 110 may be provided with an external thread structure 113, forming a through portion 114 between the external thread structure 113 and the abutment platform 112. The mounting body may be provided with a mounting hole, through which the through portion 114 passes, allowing the abutment platform 112 to abut against one side of the mounting body. A nut 115 is connected to the external thread structure 113, allowing the nut 115 to abut against the other side of the mounting body. It should be noted that the mounting body can be a wall, the housing of equipment used for fluid transport, or a mounting plate, etc. This ensures the stability of the connection between the mounting connector 110 and the mounting body and facilitates the installation or removal of the mounting connector 110 from the mounting body.

[0055] See again Figure 1 and Figure 3 The mounting connector 110 may have a first connecting section 116 and a second connecting section 117. The radial length of the first connecting section 116 may be less than the radial length of the second connecting section 117. The first connecting section 116 is used to connect to the pipe body. The second connecting section 117 is used to connect to the locking head 120. This facilitates differentiation during installation and avoids incorrect installation that could lead to increased installation time or leakage.

[0056] See also Figure 6 , Figure 7 , Figure 9 and Figure 11The lock head 120 may be provided with a sliding blocking part 181, a second elastic member 182, and a guide groove 183. The guide groove 183 may have a guide section 1831 and a fixed section 1832. In some embodiments, the guide groove 183 may be configured in an "L" shape. Of course, the guide groove 183 may also have other shapes, such as a shape in which the guide section 1831 and the fixed section 1832 form other angle configurations. The sliding blocking part 181 is movable between a third position and a fourth position by means of the second elastic member 182. In the third position, the sliding blocking part 181 covers at least part of the guide section 1831; in the fourth position, the sliding blocking part 181 opens the guide section 1831. Specifically, the sliding blocking part 181 may have a connecting surface 1811 for connecting with the lock head 120. A sliding latching part 1812 may be provided on the connecting surface 1811, and a sliding latching engagement part 126 may be provided on the lock head 120. The sliding latching part 1812 and the sliding latching engagement part 126 are slidably engaged. The sliding latching part 173 may be a buckle, and the sliding latching engagement part 126 may be a latching groove. The buckle engages into the latching groove and is latched by the groove wall, and can move within the latching groove along its extension direction. Of course, the sliding latching part 173 and the sliding latching engagement part 126 may also be other structures to suit various scenarios. The outer wall surface of the lock head 120 may protrude a limiting platform 127. The connecting surface 1811 may be recessed inward to form a receiving groove 1813. The receiving groove 1813 has a limiting wall 1814 disposed opposite to the limiting platform 127. The limiting wall 1814 can move closer to or further away from the limiting platform 127. The second elastic member 182 is located within the receiving groove 1813 and between the limiting platform 127 and the limiting wall 1814. In some embodiments, a positioning post 1815 may be provided on the limiting wall 1814 to facilitate connection with the second elastic member 182. In some embodiments, the lock head 120 is further provided with guide portions 128 on both sides of the sliding latch engagement portion 126, and the sliding blocking portion 181 is provided with corresponding guide engagement portions (not shown in the figure) on both sides of the sliding latch portion 1812. The guide portions 128 are slidably connected to the guide engagement portions, thereby further guiding the sliding of the sliding blocking portion 181 and ensuring the accuracy of the sliding trajectory. Thus, on the one hand, when the connector assembly 1 is docked, it can be locked with the components of the docking assembly through the sliding blocking part 181, the second elastic element 182 and the guide groove 183, preventing the connector assembly 1 from separating from the docking assembly on its own and affecting the stable flow of liquid; on the other hand, the sliding blocking part 181 can cover or open the guide section 1831 by pushing or pulling, preventing the components of the docking assembly from separating from the guide groove 183 due to misoperation, and the structure is simple and saves costs.

[0057] See also Figure 1 and Figure 4The lock head 120 is provided with a fixing part 190. Specifically, the fixing part 190 can be a protrusion integrally formed on the lock head 120. Of course, it is also possible that the fixing part 190 and the lock head 120 are connected separately. In this way, when the connector assembly 1 is mated, the fixing part 190 can lock the components of the mating assembly, preventing the connector assembly 1 from detaching from the mating assembly on its own and affecting the stable flow of liquid.

[0058] For example, connector assembly 1 can be configured as a female connector 3 or a male connector 2. When connector assembly 1 is configured as a male connector 2, a fourth sealing element 20 can be provided at the end of the outer wall of the second mating section 133 away from the first cavity 111. Specifically, a groove can be provided at the end of the outer wall of the second mating section 133 away from the first cavity 111, and the fourth sealing element 20 can be a sealing ring, which can be fitted into the groove. The sealing ring can be made of rubber or silicone, etc. In this way, the sealing performance is ensured after the male connector 2 is mated with the mating assembly. When connector assembly 1 is configured as a female connector 3, a fifth sealing element 30 can be provided at the end of the inner wall of the second mating section 133 away from the first cavity 111. Specifically, a groove can be provided at the end of the outer wall of the second mating section 133 away from the first cavity 111, and the fifth sealing element 30 can be a sealing ring, which can be fitted into the groove. The sealing ring can be made of rubber or silicone, etc. In this way, the sealing performance is ensured after the female connector 3 is mated with the mating assembly.

[0059] See also Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 11 , Figure 12 and Figure 13The following describes the docking and liquid flow process using two connector assemblies 1, configured as a male connector 2 and a female connector 3, as an example. The male connector 2 has a fixing part 190. The female connector 3 has a sliding blocking part 181, a second elastic element 182, and a guide groove 183. During docking, the locking cylinder 130 of the male connector 2 is inserted into the locking cylinder 130 of the female connector 3, and the locking cylinder 130 of the female connector 3 is inserted between the locking cylinder 130 of the male connector 2 and the lock head 120. The fixing part 190 passes through the guide section 1831. A pushing force is applied to move the sliding blocking part 181 to the fourth position. The fixing part 190 moves along the guide section 1831, then rotates and moves into the fixing section 1832. The pushing force is then removed, and the restoring force of the second elastic element 182 causes the sliding blocking part 181 to move to the third position, covering the guide section 1831, thereby limiting the fixing part 190 within the fixing section 1832. The locking cylinder 130 of the male connector 2 and the locking cylinder 130 of the female connector 3 abutting part 1221 are sealed by the fourth sealing element 20 and the fifth sealing element 30, respectively, and the sealing performance is further enhanced by the two seals. After the male connector 2 and the female connector 3 are axially connected, their respective connecting holes 1321 are opened. Liquid can flow from the first cavity 111, connecting hole 1321 and second cavity 131 of the male connector 2, and after reaching the female connector 3, it flows out from the second cavity 131, connecting hole and first cavity 111 of the female connector 3. In this way, when the male connector 2 and the female connector 3 are connected, only an axial thrust is needed to push the sliding blocking part 181 to the fourth position to open the guide groove 183. After the fixed part 190 enters the guide section 1831, the restoring force of the second elastic element 182 can automatically drive the sliding blocking part 181 to move to the third position to limit the fixed part 190 in the fixed section 1832. No additional operation is required, and the phenomenon of the fixed part 190 accidentally coming out of the guide groove 183 is avoided.
