Abstract

This application discloses a securely mating connector assembly for mating with at least one pair of connectors. The mating connectors include a tube portion and a locking portion. The securely mating connector assembly includes a main body, at least one connector, and at least one reinforcement member. The main body includes a tube body and at least one connector seat. Each connector seat has a mating groove and a socket. The reinforcement member includes a snap-fit ​​body with a snap-fit ​​space and forming two opposing snap-fit ​​portions. The sidewall of the snap-fit ​​portion in the direction extending from the mating groove to the socket is defined as an abutment wall. The two snap-fit ​​portions are pressed apart by the locking portion to allow the locking portion to move to the portion of the snap-fit ​​space away from the socket. The two snap-fit ​​portions of the snap-fit ​​body move closer to each other under their own elasticity so that the abutment wall corresponds to the locking portion, thereby preventing the mating connector from being pulled out of the mating groove from the socket.

Description

Technical Field

[0001] This application relates to the field of pipe connection technology, and in particular to pipe assemblies that can be securely connected. Background Technology

[0002] During pipeline installation, in order to achieve multi-directional fluid flow, the connector installed in the radial direction of the main body is usually connected to the connecting pipe so that the fluid flowing through the main body can flow into the connecting pipe through the connector.

[0003] Typically, the assembly of the connector and the joint is achieved by utilizing the cooperation between cantilever latches and ring locks on the main body, as well as the interaction between the ring locks and the connecting pipe. The cantilever latch includes an arm extending axially from the outer peripheral wall of the main body along the joint, and a claw formed at the end of the arm away from the main body. Two cantilever latches are positioned on either side of a joint with their claws facing away from each other. During assembly, the ring lock moves along the direction of the claws towards the arm, simultaneously pressing against the claws of both cantilever latches. The arms of the two cantilever latches elastically deform, causing their claws to move closer together until the ring lock is engaged with the arms of both cantilever latches. At this point, the arms of the two cantilever latches return to their original position, maintaining the assembly with the ring lock. Subsequently, during the installation of the connecting pipe, the connecting pipe moves along the direction of the hook extending towards the arm, so that the locked part of the connecting pipe applies pressure to the part of the annular lock placed between the two cantilever locks. The annular lock undergoes elastic deformation in such a way that the parts abutting against the two arms each apply pressure to the arms and move closer to each other, while the parts placed between the two cantilever locks move further apart, until the locked part of the connecting pipe passes through the annular lock and its pipe part is inserted into the connector. At this time, the annular lock returns to its original position under the action of the two arms and remains abutting against the locked part of the connecting pipe, thereby realizing the assembly of the connecting pipe.

[0004] It can be seen that the cantilever buckle is prone to elastic deformation. This makes it easy for the ring buckle to fall off and separate from the cantilever buckle when the connecting pipe is subjected to a pull-out force, resulting in easy loosening of the connecting pipe and relatively low overall connection strength. Summary of the Invention

[0005] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a securely mating connecting pipe assembly for mating with at least one pair of connecting pipes, the connecting pipes comprising a pipe portion and a locking portion formed by radial expansion of one end of the pipe portion, characterized in that the securely mating connecting pipe assembly comprises:

[0006] The main body includes a tube body and at least one connector. The tube body has a flow channel and at least one radial hole located in the radial direction of the flow channel and communicating with the flow channel. Each connector is disposed outside the portion of the tube body that forms one of the radial holes. Each connector has a mating groove and a socket communicating with the mating groove.

[0007] At least one connector has a connector channel, and the connector is installed on the connector seat such that the connector channel communicates with the radial hole and is partially placed in the mating groove and extends toward the socket, and the mating tube extends from the socket into the mating groove to seal and mate with the portion of the connector placed in the mating groove.

[0008] At least one reinforcing member, the reinforcing member including a snap-fit ​​body having a snap-fit ​​space and the portion forming the snap-fit ​​space forming two opposing snap-fit ​​portions, the snap-fit ​​body being capable of elastic deformation to bring the two snap-fit ​​portions closer together or further apart, the snap-fit ​​body being at least partially placed within the mating groove and sleeved on the portion of the connector member placed within the mating groove, the portion of the snap-fit ​​body placed within the mating groove having a size larger than the size of the socket when not elastically deformed, thus preventing it from being pulled out of the mating groove from the socket, the snap-fit ​​portion being located where the mating groove extends towards the socket. The sidewall in the direction is defined as the abutment wall. During the docking process of the connecting tube and the connector, the snap-fit ​​body undergoes elastic deformation in such a way that the two snap-fit ​​parts are squeezed apart by the snapped part to allow the snapped part to move to the snap-fit ​​space located at the part of the snap-fit ​​part away from the socket, and the connecting tube is snapped into the snap-fit ​​space with the tube part placed between the two snap-fit ​​parts. The two snap-fit ​​parts of the snap-fit ​​body move closer to each other under their own elastic action so that the abutment wall corresponds to the snapped part, thereby preventing the connecting tube from being pulled out of the docking groove from the socket.

[0009] According to one embodiment of this application, the connector further has at least one unlocking port, which communicates with the mating groove. The snap-fit ​​body is snapped into the mating groove by the portion located between the two snap-fit ​​parts snapping into the unlocking port. The portion of the snap-fit ​​body located at the unlocking port is pressed to cause the snap-fit ​​body to elastically deform in such a way that the two snap-fit ​​parts move away from each other, so that the abutment wall is misaligned with the snapped portion of the connecting tube assembled on the connector. At this time, the connecting tube is unlocked, and the connecting tube can be pulled out of the socket from the mating groove to separate from the connector.

[0010] According to one embodiment of this application, the connector is detachably connected to the connector base.

[0011] According to one embodiment of this application, the connector has a set of slots and an opening located in a direction parallel to the axial direction of the corresponding radial hole. An unlocking port is provided and faces the opening. The set of slots includes a first slot and a second slot. Each radial hole has a first slot, a second slot, a mating groove, and a insertion port sequentially distributed on the side away from the flow channel. The radial hole communicates with the second slot through the first slot, and the first slot communicates with the mating groove through the second slot. The opening communicates with the first slot, the second slot, and the mating groove. The connector slides corresponding to the opening so that one end slides into the first slot and the other end slides into the second slot and partially extends from the second slot into the mating groove. The connector is sealed to the portion of the tube body that forms the corresponding radial hole in such a way that the connector channel communicates with the radial hole.

[0012] According to one embodiment of this application, the reinforcement further includes a blocking body connected to the snap-fit ​​body and installed on one end of the connector where the opening is formed to cover at least a portion of the opening to prevent the connector from sliding out.

[0013] According to one embodiment of this application, the floating, securely dockable connecting pipe assembly further includes at least one locking member, and the blocking body covering at least part of the opening is locked to the connecting seat through the locking member to prevent the connector from sliding out of the opening.

[0014] According to one embodiment of this application, the blocking body has at least one insertion hole, and the end of the connecting seat forming the opening forms at least one mounting hole. The locking member is threadedly engaged with the mounting hole, and the locking member passes through the insertion hole and is threadedly connected to the mounting hole to lock the blocking body to the connecting seat.

[0015] According to one embodiment of this application, the reinforcement further includes an abutment formed on the blocking body and disposed on the same side as the snap-fit ​​body. When the reinforcement is installed on the connector, the abutment extends into the second slot through the opening to remain corresponding to a portion of the peripheral wall of the connector, thereby limiting the degree of translation or deflection of the connector.

[0016] According to one embodiment of this application, the connector includes a connector body and a sealing assembly. The connector body includes a head and a rod. The head is formed by radially expanding one end of the rod. The head and the rod together form the connector channel. The sealing assembly includes a first seal, which is installed at the end of the head away from the rod. The connector body slides corresponding to the opening so that the head slides into the first slot and the rod slides into the second slot and partially extends into the mating groove. The connector body installed on the connector seat communicates with the radial hole in such a way that the first seal seals against the side wall of the first slot near the corresponding radial hole and the connector channel at least partially corresponds to the radial hole.

[0017] According to one embodiment of this application, when the snap-fit ​​body is assembled to the connector seat, the distance between the abutting wall and the side wall of the mating groove near the second snap-fit ​​groove is greater than the size of the snapped part in the axial direction of the tube. When the snap-fit ​​body does not undergo elastic deformation, the size of the snap-fit ​​space located on the side of the snap-fit ​​part away from the socket in a plane perpendicular to the axial direction of the radial hole is greater than the size of the snapped part in a plane parallel to the axial direction of the tube. The side walls of the first snap-fit ​​groove, the second snap-fit ​​groove, and the mating groove corresponding to the peripheral wall of the connector body each have at least a partial gap with the connector body. The first seal can undergo elastic deformation to allow the connector body to be deflected so that the axis of the connector body forms an angle with the axis of the corresponding radial hole.

[0024] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0025] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 6 A preferred embodiment of the present application of a securely mating connector assembly will be described in detail below. The securely mating connector assembly is used to mate with at least one pair of connectors 90, each connector 90 including a tube portion 91 and a locking portion 92 formed by radially expanding one end of the tube portion 91.

[0028] The securely mating connecting pipe assembly includes a main body 10, which includes a pipe body 11 and at least one connecting seat 12. The pipe body 11 has a flow channel 1101 and at least one radial hole 1102 located radially on and communicating with the flow channel 1101. Each connecting seat 12 is disposed outside the portion of the pipe body 11 where the radial hole 1102 is formed. Each connecting seat 12 has a mating groove 1201 and a socket 1202 communicating with the mating groove 1201.

[0029] Preferably, the connecting seat 12 and the tube body 11 are integrally injection molded.

[0030] The securely mating connecting pipe assembly includes at least one connector 20, which has a connector channel 201. The connector 20 is mounted to the connector base 12 such that the connector channel 201 communicates with the radial hole 1102 and is partially positioned in the mating groove 1201 and extends toward the socket 1202. The mating pipe 90 extends from the socket 1202 into the mating groove 1201 to seal and mate with the portion of the connector 20 positioned in the mating groove 1201.

[0031] Furthermore, the securely mating connecting pipe assembly further includes at least one reinforcing member 30, which includes a snap-fit ​​body 31. The snap-fit ​​body 31 has a snap-fit ​​space 3101, and the portion forming the snap-fit ​​space 3101 forms two opposing snap-fit ​​portions 311. The snap-fit ​​body 31 is capable of elastic deformation to bring the two snap-fit ​​portions 311 closer together or further apart. The snap-fit ​​body 31 is at least partially placed within the mating groove 1201 and sleeved on the portion of the connector 20 placed within the mating groove 1201.

[0032] When the snap-fit ​​body 31 does not undergo elastic deformation, the portion of the snap-fit ​​body 31 that is located within the mating groove 1201 is larger than the size of the insertion port 1202, thus preventing it from being pulled out of the mating groove 1201 from the insertion port 1202. The side wall of the snap-fit ​​portion 311 located in the direction extending from the mating groove 1201 toward the insertion port 1202 is defined as the abutment wall 3111. During the docking process between the connector 90 and the connector 20, the snap-fit ​​body 31 elastically deforms such that the two snap-fit ​​portions 311 are squeezed apart by the snapped portion 92, allowing the snapped portion 92 to move to the snap-fit ​​space 3101 located at the portion of the snap-fit ​​portion 311 away from the socket 1202, and the connector 90 is snapped into the snap-fit ​​space 3101 with the tube portion 91 placed between the two snap-fit ​​portions 311. Subsequently, the two snap-fit ​​portions 311 of the snap-fit ​​body 31 move closer to each other under their own elastic action, so that the abutment wall 3111 corresponds to the snapped portion 92, thereby preventing the connector 90 from being pulled out of the docking groove 1201 from the socket 1202.

[0033] In this way, by engaging the snap-fit ​​body 31 with the docking groove 1201, the difficulty of the snap-fit ​​body 31 being pulled out of the docking groove 1201 from the insertion port 1202 and separated from the connecting seat 12 is increased. Compared with using a cantilever buckle for snap-fit, this increases the difficulty of disassembly, makes the assembly more secure, and meets the usage requirements.

[0034] Preferably, multiple radial holes 1102 are provided, and the number of connecting seats 12, connectors 20 and snap-fit ​​bodies 31 is the same as the number of radial holes 1102, so as to realize the simultaneous docking of multiple connecting pipes 90.

[0035] Furthermore, the connector 12 also has at least one unlocking port 1203, which communicates with the mating groove 1201. The snap-fit ​​body 31 engages with the mating groove 1201 with the portion between the two snap-fit ​​parts 311 engaging with the unlocking port 1203. When the portion of the snap-fit ​​body 31 located at the unlocking port 1203 is pressed, the snap-fit ​​body 31 elastically deforms so that the two snap-fit ​​parts 311 move away from each other, causing the abutment wall 3111 to be misaligned with the locked portion 92 of the connecting tube 90 assembled on the connector 20. At this time, the connecting tube 90 is unlocked, and the connecting tube 90 can be pulled out of the socket 1202 from the mating groove 1201 to separate from the connector 20.

[0036] Preferably, the connector 20 is detachably connected to the connector 12.

[0037] Further, the connecting seat 12 has a set of slots 1204 and an opening 1205 located in a direction parallel to the axial direction of the corresponding radial hole 1102. An unlocking port 1203 is provided and faces the opening 1205. The set of slots 1204 includes a first slot 12041 and a second slot 12042. On the side of each radial hole 1102 away from the flow channel 1101, a first slot 12041, a second slot 12042, a mating groove 1201, and a insertion port 1202 are sequentially distributed. The radial hole 1102 communicates with the second slot 12042 through the first slot 12041, and the first slot 12041 communicates with the mating groove 1201 through the second slot 12042. The opening 1205 communicates with the first slot 12041, the second slot 12042, and the mating groove 1201. The connector 20 slides in relation to the opening 1205 such that one end slides into the first slot 12041 and the other end slides into the second slot 12042 and partially extends from the second slot 12042 into the mating groove 1201. The connector 20 is sealed to the portion of the tube body 11 that forms the radial hole 1102 in such a way that the connector channel 201 communicates with the radial hole 1102.

[0038] In this way, based on the plug-in engagement between the connector 20 and the connecting seat 12, compared with fixing the connector 20 by welding, the assembly efficiency is improved, the operating cost is reduced, and the problem of welding overflow is avoided, thus ensuring the assembly quality.

[0039] Preferably, since the docking groove 1201 is connected to the opening 1205, the snap-fit ​​body 31 slides into the docking groove 1201 from the opening 1205 when it is sleeved on the connector 20, so as to complete the assembly of the snap-fit ​​body 31 with the connecting seat 12 and the connector 20. Compared with the snap-fit ​​using a cantilever buckle, the assembly difficulty is greatly reduced and the required assembly force is smaller.

[0040] Furthermore, the reinforcement member 30 also includes a blocking body 32, which is connected to the snap-fit ​​body 31 and installed at one end of the connector 12 where the opening 1205 is formed to cover at least part of the opening 1205, thereby preventing the connector 20 from sliding out. This further improves the firmness of the connector 20's assembly with the connector 12 based on the plug-in engagement between the connector 20 and the connector 12. Simultaneously, because the snap-fit ​​body 31 is connected to the blocking body 32, the snap-fit ​​body 31 is locked together to prevent it from shifting and affecting the assembly of the connecting tube 90.

[0041] Preferably, the blocking body 32 is installed on the connecting seat 12 in such a way that it covers the portion of the opening 1205 that corresponds to the slot group 1204.

[0042] Preferably, the floating, securely dockable connecting pipe assembly further includes at least one locking element 40, and the blocking body 32 that covers at least part of the opening 1205 is locked to the connecting seat 12 by the locking element 40 to prevent the connector 20 from sliding out of the opening 1205.

[0043] Preferably, the blocking body 32 has at least one insertion hole 3201, and the end of the connecting seat 12 forming the opening 1205 forms at least one mounting hole 1206, and the locking member 40 is threadedly engaged with the mounting hole 1206. The locking member 40 passes through the insertion hole 3201 and is threadedly connected to the mounting hole 1206 to lock the blocking body 32 to the connecting seat 12.

[0044] Preferably, the locking member 40 is implemented as a self-tapping screw.

[0045] Furthermore, the blocking body 32 has two spaced-apart limiting portions 321, which are disposed on the same side as the snap-fit ​​body 31. The blocking body 32 blocks at least part of the opening 1205 by placing the two limiting portions 321 on both sides of the portion of the connecting seat 12 that forms the opening 1205, so as to achieve the positioning and installation of the reinforcement 30 by utilizing the cooperation between the blocking body 32 and the connecting seat 12.

[0046] Further, the connector 20 includes a connector body 21 and a sealing assembly 22. The connector body 21 includes a head 211 and a rod 212. The head 211 is formed by radially expanding one end of the rod 212, and the head 211 and the rod 212 together form the connector channel 201. The sealing assembly 22 includes a first seal 221, which is installed at the end of the head 211 away from the rod 212. The connector body 21 slides corresponding to the opening 1205 so that the head 211 slides into the first slot 12041 and the rod 212 slides into the second slot 12042 and partially extends into the mating groove 1201. The connector body 21, installed on the connector seat 12, connects to the radial hole 1102 by sealing the first seal 221 against the side wall of the first slot 12041 near the corresponding radial hole 1102, and by at least partially corresponding the connector channel 201 to the radial hole 1102. In this way, based on the integral injection molding of the main body 10, the axial dimension of the first slot 12041 relative to the radial hole 1102 remains constant, ensuring that the compressive force of the first seal 221 remains within a predetermined range, thus guaranteeing a sealing effect and extending service life.

[0047] Preferably, when the snap-fit ​​body 31 is assembled to the connector seat 12, the distance between the abutment wall 3111 and the side wall of the mating groove 1201 near the second snap-fit ​​groove 12042 is greater than the dimension of the snapped portion 92 in the axial direction of the tube portion 91. When the snap-fit ​​body 31 does not undergo elastic deformation, the dimension of the snap-fit ​​space 3101 located on the side of the snap-fit ​​portion 311 away from the insertion port 1202 in a plane perpendicular to the axial direction of the radial hole 1102 is greater than the dimension of the snapped portion 92 in a plane perpendicular to the axial direction of the tube portion 91. In addition, the side walls of the first snap-fit ​​groove 12041, the second snap-fit ​​groove 12042, and the mating groove 1201 corresponding to the peripheral wall of the connector body 21 are at least partially gapped from the connector body 21. In this way, there is sufficient space to allow the connector body 21 to move in a direction perpendicular to the axial direction of the radial hole 1102, so that the connector channel 201 is parallel or coaxial with the axial direction of the radial hole 1102. Furthermore, the first sealing element 221 can undergo elastic deformation to allow the connector body 21 to be deflected, causing the axis of the connector body 21 to form an angle with the axis of the corresponding radial hole 1102. In summary, the connector body 21 of this application can translate or deflect to allow the main body 10 to be floatingly connected to the connecting pipe 90 via the connector body 21, meaning the connecting pipe 90 can be oriented off-axis to the radial hole 1102, increasing assembly convenience and reducing assembly difficulty. Additionally, based on the snap-fit ​​engagement between the connector 20 and the connecting seat 12, compared to fixing the connector 20 by welding, welding overflow that could affect the movement of the connector 20 is avoided.

[0048] Furthermore, the sealing assembly 22 includes at least one second sealing element 222, which is sleeved on the rod portion 212. The rod portion 212 of the connector body 21 is inserted into the tube portion 91 and sealed to the tube portion 91 through the second sealing element 222.

[0049] Preferably, the second seal 222 is implemented as a sealing ring.

[0050] Preferably, each of the sealing groups 22 has a plurality of second seals 222, and the plurality of second seals 222 are distributed at intervals along the axial direction of the rod portion 212, so as to improve the sealing performance of the mating of the connecting pipe 90 and the rod portion 212 by the cooperation of the plurality of second seals 222.

[0051] Preferably, the peripheral wall of the rod portion 212 forms at least one groove 21201, and each of the second seals 222 is fitted to the rod portion 212 by snapping into one of the grooves 21201.

[0052] Furthermore, the reinforcing member 30 also includes an abutment 33, which is disposed on the same side as the snap-fit ​​member 31. The abutment 33 is formed on the blocking member 32 and located between the two limiting portions 321. When the reinforcing member 30 is installed on the connecting seat 12, the abutment 33 extends through the opening 1205 into the second slot 12042 to maintain a position corresponding to a portion of the peripheral wall of the connector 20, thereby limiting the degree of translation or deflection of the connector 20.

[0053] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.

The reliably mating connecting pipe assembly according to claim 6, characterized in that, The blocking body has at least one insertion hole, and the end of the connecting seat that forms the opening forms at least one mounting hole. The locking member is threadedly engaged with the mounting hole, and the locking member passes through the insertion hole and is threadedly connected to the mounting hole to lock the blocking body to the connecting seat.

8. The reliably mating connecting pipe assembly according to claim 7, characterized in that, The reinforcement also includes an abutment formed on the blocking body and disposed on the same side as the snap-fit ​​body. When the reinforcement is installed on the connector, the abutment extends into the second slot through the opening to remain in correspondence with a portion of the peripheral wall of the connector, thereby limiting the degree of translation or deflection of the connector.

9. The reliably mating connecting pipe assembly according to claim 8, characterized in that, The connector includes a connector body and a sealing assembly. The connector body includes a head and a rod. The head is formed by radially expanding one end of the rod. The head and the rod together form the connector channel. The sealing assembly includes a first seal, which is installed at the end of the head away from the rod. The connector body slides corresponding to the opening so that the head slides into the first slot and the rod slides into the second slot and partially extends into the mating groove. The connector body, installed on the connector seat, communicates with the radial hole in such a way that the first seal seals against the side wall of the first slot near the corresponding radial hole and the connector channel at least partially corresponds to the radial hole.

10. The reliably mating connecting pipe assembly according to claim 9, characterized in that, When the snap-fit ​​body is assembled with the connector seat, the distance between the abutting wall and the side wall of the mating groove near the second snap-fit ​​groove is greater than the size of the snapped part in the axial direction of the pipe. When the snap-fit ​​body does not undergo elastic deformation, the size of the snap-fit ​​space located on the side of the snap-fit ​​part away from the socket in a plane perpendicular to the axial direction of the radial hole is greater than the size of the snapped part in a plane parallel to the axial direction of the pipe. The side walls of the first snap-fit ​​groove, the second snap-fit ​​groove, and the mating groove corresponding to the peripheral wall of the connector body each have at least a gap with the connector body. The first seal can undergo elastic deformation to allow the connector body to be deflected so that the axis of the connector body and the axis of the corresponding radial hole form an angle.
