Description

Technical Field

[0001] This application relates to the field of automotive piping, and in particular to a connection structure for piping and connectors. Background Technology

[0002] With the rapid development of the automotive industry, the complexity and diversity of automotive piping systems are constantly increasing. Inside a car, piping needs to be laid out and connected in a complex manner within a limited space, which places higher demands on the connection structure of piping and connectors.

[0003] When connecting automotive pipelines, the pipelines and connectors are often connected using traditional threaded connections or welding. Welded connections are difficult to replace when the pipeline is damaged, while threaded connections meet the maintenance needs of replacing pipelines or connectors.

[0004] In practical applications, threaded connections for pipes and fittings require tightening, which can be problematic in confined spaces, such as insufficient tool access or limited tool movement, leading to inconvenience during installation and disassembly. Furthermore, in repair scenarios requiring rapid assembly and disassembly, the tightening of threaded connections is time-consuming, failing to meet the demands of efficient repair. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that the use of threaded connections for pipes and joints requires tightening operations, which may lead to problems such as tools not being able to reach the operating space or the limited space for tool movement, resulting in inconvenience in installation and disassembly operations. This application provides a connection structure for pipes and joints.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A connection structure for a pipeline and a connector includes an automotive pipeline, one end of which is provided with a connector, a plug is fixed on the connector, a limit ring is fixed on the connector, the limit ring corresponds to the automotive pipeline, and a connection and fixing mechanism is provided between the automotive pipeline and the limit ring.

[0007] By adopting the above technical solution, the plug on the connector can be directly inserted into the connecting pipe, and the automotive pipeline abuts against the limiting ring of the connector. When the plug on the connector is inserted into the automotive pipeline, the connecting and fixing mechanism connects the automotive pipeline with the limiting ring, thereby making it easy to connect the automotive pipeline with the connector and reducing the possibility of difficulty in operation due to limited space when replacing internal automotive pipelines.

[0008] Furthermore, the connection and fixing mechanism includes a support ring fixed on the vehicle pipeline, three circumferentially distributed connecting plates fixed on the support ring, a connecting pipe fixed on the limiting ring, a plane corresponding to the connecting plate on the connecting pipe, and a snap-fit ​​assembly between the connecting pipe and the connecting plate.

[0009] By adopting the above technical solution, the connecting plate on the support ring is inserted into the connecting pipe, and the connecting pipe and the connecting plate are fixed together by the snap-fit ​​assembly. This makes it easy to connect the car pipes and the connecting joints, reducing the possibility of difficulty in operation due to limited space when replacing the internal pipes of the car.

[0010] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​plate slidably connected to the connecting plate, and both the snap-fit ​​plate and the connecting plate are provided with snap-fit ​​teeth facing opposite directions.

[0011] By adopting the above technical solution, when the connecting plate is inserted into the connecting pipe, the locking teeth on the locking plate and the locking teeth on the connecting pipe are locked together, thereby making it easy to fix the connecting plate and the connecting pipe together.

[0012] Furthermore, a snap-fit ​​spring is provided between the snap-fit ​​plate and the connecting plate, and both ends of the snap-fit ​​spring are fixedly connected to the snap-fit ​​plate and the connecting plate.

[0013] By adopting the above technical solution, the snap-fit ​​plate is supported by the snap-fit ​​spring, so that the snap-fit ​​teeth on the snap-fit ​​plate can stably engage with the snap-fit ​​teeth on the connecting pipe.

[0014] Furthermore, a lever is fixed to one end of the snap-fit ​​plate, and the lever is slidably connected to the connecting plate.

[0015] By adopting the above technical solution, the lever drives the snap-fit ​​plate, causing the snap-fit ​​plate to move away from the connecting pipe, thereby facilitating the separation of the snap-fit ​​plate from the connecting pipe.

[0016] Furthermore, a latching block is rotatably connected to the side of the lever away from the latching plate, and the latching block is L-shaped.

[0017] By adopting the above technical solution, the locking block is rotated and locked onto the connecting plate, thus facilitating the limiting of the locking plate and reducing the possibility of it falling back and affecting the separation of the automotive pipeline and the connecting joint. Furthermore, a sealing ring one is fixed to the side of the limiting ring facing the connecting pipe, and a sealing ring two is fixed to the end of the automotive pipeline facing the sealing ring one. Both the sealing ring one and the sealing ring two are provided with sealing grooves.

[0018] By adopting the above technical solution, the sealing ring one on the automotive pipeline abuts against the sealing ring two on the limiting ring, thereby improving the sealing performance of the connection between the automotive pipeline and the connecting joint.

[0019] Furthermore, a sealing sleeve is fixed to the end of the connector facing the vehicle pipeline, and the sealing sleeve has evenly distributed sealing teeth.

[0020] By adopting the above technical solution, the sealing sleeve on the connector is squeezed and inserted into the vehicle pipeline, thereby further improving the sealing performance between the vehicle pipeline and the connector.

[0021] In summary, this application includes at least one of the following beneficial effects: 1. In this application, when connecting the automotive pipeline to the connector, the plug on the connector is first inserted into the automotive pipeline, allowing the automotive pipeline to abut against the limiting ring. Simultaneously, the connecting tube on the limiting ring and the connecting plate fixed on the support ring move closer together, aligning the plane of the connecting plate with the plane of the connecting tube. At the same time, the snapping teeth on the snapping plate align with the inclined surfaces of the snapping teeth on the connecting tube. Then, the snapping plate slides on the connecting tube. When the automotive pipeline is fully abutting against the limiting ring, the snapping spring pushes the snapping plate, causing the snapping teeth on the snapping plate to engage with the snapping teeth on the connecting tube, keeping the automotive pipeline in contact and fixed against the limiting ring. Simultaneously, the connecting tube abuts against the support ring, completing the connection between the automotive pipeline and the connector. When it is necessary to separate the automotive piping from the connector, move the lever to move the clamping plate away from the connector. Then rotate the clamping lever to lock it onto the connector, preventing the clamping plate from falling back. Without the clamping plate's limiting function, the automotive piping can be directly separated from the connector, making it easy to connect the automotive piping to the connector and reducing the possibility of difficulty in operation due to limited space when replacing internal automotive piping.

[0022] 2. In this application, when the automotive pipeline comes into contact with the limiting ring, the sealing ring one on the automotive pipeline comes into contact with the sealing ring two on the limiting ring, and the sealing grooves opened on the sealing ring one and the sealing ring two are misaligned and come into contact with each other. When the plug on the connector is inserted into the automotive pipeline, the sealing sleeve on the plug is squeezed and inserted into the automotive pipeline, thereby achieving the purpose of improving the sealing performance of the connection between the automotive pipeline and the connector.

[0025] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0026] This application discloses a connection structure for pipes and connectors.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A connection structure for a pipeline and a connector includes a vehicle pipeline 1, a connector 2 at one end of the vehicle pipeline 1, a plug connector 3 fixed on the connector 2, a limit ring 4 fixed on the connector 2, the limit ring 4 corresponding to the vehicle pipeline 1, and a connection fixing mechanism 5 between the vehicle pipeline 1 and the limit ring 4.

[0028] When connecting the vehicle pipe 1 to the connector 2, the plug 3 on the connector 2 is directly inserted into the connecting pipe 52, with the vehicle pipe 1 abutting against the limiting ring 4 of the connector 2. As the plug 3 on the connector 2 is inserted into the vehicle pipe 1, the connecting and fixing mechanism 5 connects the vehicle pipe 1 to the limiting ring 4, completing the connection between the vehicle pipe 1 and the connector 2. By inserting the plug 3 on the connector 2 into the vehicle pipe 1 and then using the connecting and fixing mechanism 5 to connect the limiting ring 4 to the vehicle pipe 1, the vehicle pipe 1 and the connector 2 can be easily connected, reducing the possibility of difficulty in operation due to limited space when replacing internal vehicle pipes.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The connecting and fixing mechanism 5 includes a support ring 51 fixed on the vehicle pipeline 1, three circumferentially distributed connecting plates 54 fixed on the support ring 51, a connecting pipe 52 fixed on the limiting ring 4, a plane corresponding to the connecting plate 54 on the connecting pipe 52, and a snap-fit ​​component 53 between the connecting pipe 52 and the connecting plate 54.

[0030] In addition, the snap-fit ​​assembly 53 includes a snap-fit ​​plate 531 that is slidably connected to the connecting plate 54, and both the snap-fit ​​plate 531 and the connecting plate 54 are provided with snap-fit ​​teeth 532 facing opposite directions.

[0031] Furthermore, a snap-fit ​​spring 533 is provided between the snap-fit ​​plate 531 and the connecting plate 54, and both ends of the snap-fit ​​spring 533 are fixedly connected to the snap-fit ​​plate 531 and the connecting plate 54.

[0032] Furthermore, a lever 534 is fixed to one end of the snap-fit ​​plate 531, and the lever 534 is slidably connected to the connecting plate 54.

[0033] Furthermore, a latching block 6 is rotatably connected to the side of the lever block 534 away from the latching plate 531, and the latching block 6 is L-shaped.

[0034] When connecting the vehicle pipeline 1 to the connector 2, first insert the plug 3 on the connector 2 into the vehicle pipeline 1, so that the vehicle pipeline 1 rests against the limiting ring 4. At the same time, the connecting tube 52 on the limiting ring 4 and the connecting plate 54 fixed on the support ring 51 move closer to each other, so that the plane on the connecting plate 54 corresponds to the plane on the connecting tube 52. At the same time, the locking teeth 532 on the locking plate 531 on the connecting plate 54 correspond to the inclined surfaces of the locking teeth 532 on the connecting tube 52. Then, the locking plate 531 slides on the connecting tube 52. When the vehicle pipeline 1 is fully against the limiting ring 4, the locking spring 533 pushes the locking plate 531, so that the locking teeth 532 on the locking plate 531 and the locking teeth 532 on the connecting tube 52 are locked together, so that the vehicle pipeline 1 and the limiting ring 4 remain against each other and fixed. At the same time, the connecting tube 52 rests against the support ring 51, completing the connection between the vehicle pipeline 1 and the connector 2. When it is necessary to separate the automotive pipe 1 from the connector 2, move the lever 534 to move the locking plate 531 away from the connecting pipe 52. Then rotate the locking block 6 to lock it onto the connecting plate 54, preventing the locking plate 531 from falling back. If the locking plate 531 is not in place, simply separate the automotive pipe 1 from the connector 2. When the connector 3 on the connector 2 is inserted into the automotive pipe 1, the locking plate 531 on the connecting plate 54 engages with the connecting pipe 52, ensuring that the automotive pipe 1 and the connector 2 can only approach each other. This facilitates connection between the automotive pipe 1 and the connector 2 and reduces the possibility of difficulty in operation due to limited space when replacing internal automotive pipes.

[0035] Reference Figure 3 and Figure 4A sealing ring 7 is fixed to the side of the limiting ring 4 facing the connecting pipe 52, and a sealing ring 8 is fixed to the end of the vehicle pipeline 1 facing the sealing ring 7. Both the sealing ring 7 and the sealing ring 8 have sealing grooves. When the vehicle pipeline 1 abuts against the limiting ring 4, the sealing ring 7 on the vehicle pipeline 1 abuts against the sealing ring 8 on the limiting ring 4, and the sealing grooves on the sealing rings 7 and 8 are offset and abut together. When the vehicle pipeline 1 abuts against the limiting ring 4, the sealing rings 7 and 8 are located between the vehicle pipeline 1 and the limiting ring 4, thereby improving the sealing performance of the connection between the vehicle pipeline 1 and the connecting joint 2.

[0036] Reference Figure 3 and Figure 4 A sealing sleeve 9 is fixed to the end of the connector 2 facing the vehicle pipeline 1. The sealing sleeve 9 has evenly distributed sealing teeth. When the connector 3 on the connector 2 is inserted into the vehicle pipeline 1, the sealing sleeve 9 on the connector 3 is forced into the vehicle pipeline 1. By fixing the sealing sleeve 9 to the connector 3 and then allowing the sealing sleeve 9 to abut against the inner wall of the vehicle pipeline 1, the sealing performance between the vehicle pipeline 1 and the connector 2 can be further improved.

[0037] Working principle: When connecting the vehicle pipeline 1 to the connector 2, the plug 3 on the connector 2 is directly inserted into the connecting pipe 52, and the sealing sleeve 9 on the plug 3 is squeezed into the vehicle pipeline 1. When the vehicle pipeline 1 abuts against the limiting ring 4 of the connector 2 and the plug 3 is inserted into the vehicle pipeline 1, the connecting pipe 52 on the limiting ring 4 and the connecting plate 54 fixed on the support ring 51 move closer to each other, so that the connecting plate 54 corresponds to the plane on the connecting pipe 52. At the same time, the locking teeth 532 on the locking plate 531 on the connecting plate 54 correspond to the inclined surfaces of the locking teeth 532 on the connecting pipe 52, and then the locking plate 531 slides on the connecting pipe 52. When the vehicle pipeline 1 is fully against the limiting ring 4, the snap-fit ​​spring 533 pushes the snap-fit ​​plate 531, causing the snap-fit ​​teeth 532 on the snap-fit ​​plate 531 to snap together with the snap-fit ​​teeth 532 on the connecting pipe 52, keeping the vehicle pipeline 1 against the limiting ring 4. At the same time, the sealing ring 7 on the vehicle pipeline 1 abuts against the sealing ring 8 on the limiting ring 4, and the sealing grooves on the sealing ring 7 and the sealing ring 8 are offset and abut together. Meanwhile, the connecting pipe 52 abuts against the support ring 51, completing the connection between the vehicle pipeline 1 and the connecting connector 2.
