Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipe technology, specifically to an easy-to-install automotive air conditioning pipe. Background Technology

[0002] With the development of the automotive industry, driving comfort has become a crucial factor for consumers when choosing a vehicle. As a key component for enhancing comfort, the automotive air conditioning system significantly improves the driving experience by precisely regulating the cabin temperature and has now become a standard feature in modern cars. In the automotive air conditioning system, the piping serves as a critical channel for refrigerant delivery, and its ease of installation directly affects the overall vehicle assembly efficiency and the convenience of subsequent maintenance. Existing technology discloses an automotive air conditioning piping system using a connecting sleeve structure, where piping is connected via bolts. While this is an improvement over traditional welding methods, it still has significant shortcomings. This structure requires tightening or loosening multiple bolts individually during installation and disassembly, a cumbersome and time-consuming process, especially when working in the confined space of a car, where limited tool space further increases assembly difficulty. Furthermore, frequent bolt removal and installation can lead to thread wear, affecting connection sealing and structural stability. In vehicle maintenance scenarios, this connection method not only increases the workload of maintenance personnel but also prolongs maintenance time and increases maintenance costs. More importantly, traditional bolt connections are difficult to implement for rapid emergency handling, potentially delaying appropriate action in special situations requiring urgent pipe disassembly. In response to the aforementioned technical shortcomings, the industry urgently needs to develop a solution for connecting automotive air conditioning pipes that can both ensure connection reliability and enable quick assembly and disassembly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a convenient automotive air conditioning pipe, comprising: a pipe body and a disassembly and assembly mechanism; A throttle valve is fixedly installed at one end of the pipeline body, and a connecting pipe is connected to the end of the throttle valve away from the pipeline body.

The disassembly and assembly mechanism includes an annular support block fixedly mounted on the connecting pipe and a connecting block fixedly connected to the outside of the connector. A plug-in rod is fixedly connected to the side of the annular support block near the connector. A through groove for inserting the plug-in rod is provided inside the connecting block. A groove is provided inside the plug-in rod. A limit spring is fixedly connected to the inner wall of the groove. A movable clamping block is fixedly connected to one end of the limit spring. The movable clamping block is movably connected inside the groove.

[0005] By adopting the above technical solution, after the connecting pipe is inserted into the connecting hole of the connector, the gas generated by the air conditioner at the connector can enter the pipeline body through the connecting pipe and the throttle valve, so that the pipeline body can input the gas into the interior of the carriage for temperature regulation; in addition, when the connecting pipe is inserted into the connecting hole, it can drive the annular support block to fit against one side of the connector, so that the insertion rod can pass through the through groove of the connecting block, and the movable clamping block can be squeezed into the groove by the inner wall of the through groove. When the movable clamping block loses the squeezing force of the inner wall of the through groove, it can be moved out of the groove again under the tension force of the limit spring, so that the movable clamping block after being moved out can press the connecting block against the annular support block, thereby completing the stable connection between the connecting pipe and the connector.

[0006] Preferably, a rubber pad is fixedly connected to the side of the movable clamp block away from the limiting spring.

[0008] Preferably, a sealing gasket is fixedly connected to the side of the annular support block near the connector, and the sealing gasket is fixedly fitted onto the outer wall of the connecting pipe.

[0009] By adopting the above technical solution, gas can be prevented from flowing out from the gap between the connecting hole and the connecting pipe, thereby improving the sealing performance after the connecting pipe is inserted into the connector.

[0010] Preferably, there are two connecting blocks and two plug-in rods. The two connecting blocks are symmetrically arranged on the outer side of the connector, and the two plug-in rods are symmetrically arranged on one side of the annular support block.

[0011] By adopting the above technical solutions, the stability of the connecting pipe and connector after installation can be improved.

[0012] Preferably, the inner wall of the groove is provided with a sliding groove, and a slider is slidably connected to the inner wall of the sliding groove.

[0013] By adopting the above technical solution, it is possible to maintain stability when the movable clamping block moves.

[0014] Preferably, one side of the slider is fixedly connected to the movable clamping block.

[0015] By adopting the above technical solution, the movable clamping block can move along a straight trajectory, thereby improving the stability of the movable clamping block when it is pressed against the connecting block.

[0016] Preferably, the side of the connector away from the connecting pipe is fixedly connected to the car air conditioning duct, and the side of the connecting hole is connected to the car air conditioning duct.

[0018] In summary, this application includes at least one of the following beneficial technical effects: This easy-to-install automotive air conditioning pipe features a disassembly and assembly mechanism between the pipe body and the connector. After the connector is inserted into the connection hole, the annular support block fits against the connector, allowing the insertion rod to pass through the slot.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address these issues, researchers noticed the efficiency limitations of traditional bolt-fastening methods and began exploring the possibility of rapid assembly and disassembly. By analyzing the stress characteristics at pipe connections, they discovered that axial insertion combined with an elastic snap-fit ​​structure could replace threaded fastening. After multiple tests, they determined that a solution using a pre-compressed spring and a movable locking block could automatically lock during insertion, eliminating the need for rotation. Therefore, as Figures 1 to 4 As shown, this application proposes a convenient automotive air conditioning pipe system, comprising a pipe body 1 and a disassembly / assembly mechanism 2. A throttle valve 10 is installed at the end of the pipe body 1, and the throttle valve 10 is connected to a connecting pipe 12 with a connector 11. A connection hole 13 is formed inside the connector 11. The disassembly / assembly mechanism 2 includes an annular support block 20 fitted onto the connecting pipe 12 and a connecting block 21 fixed to the connector 11. The support block has a plug-in rod body 23 with a groove 24. A movable clamping block 26 driven by a limiting spring 25 is installed inside the groove 24. The connecting block 21 has a through groove 22 for the plug-in rod to pass through. The annular support block 20 is an annular structure fitted onto the outer wall of the connecting pipe 12. It can be made of cast aluminum alloy and is used to provide axial support and support the insertion rod 23. The insertion rod 23 is a columnar component extending from the support block. It can be made of stainless steel tubing, and its internal groove 24 is used to accommodate the movable clamping block 26 assembly. The movable clamping block 26 is a spring-driven wedge-shaped block. It can be injection molded from nylon material and achieves a self-locking function through elastic deformation during insertion. The limiting spring 25 is a pre-compressed helical spring. It can be made of spring steel and is used to provide continuous clamping force to the movable clamping block 26. Specifically, during installation, the connecting pipe 12 is inserted into the connecting hole 13, causing the annular support block 20 to press against the end face of the connector 11. Simultaneously, the insertion rod 23 is inserted into the through groove 22 of the connecting block 21, and the movable clamping block 26 is compressed back into the groove 24 by the inner wall of the through groove 22. After the insertion rod has completely passed through the through groove 22, the movable clamping block 26 pops out under the action of the limiting spring 25, forming mechanical interference with the outer surface of the connecting block 21. At this time, the connecting block 21 is clamped between the movable clamping block 26 and the annular support block 20, achieving axial fixation. During disassembly, pressing the movable clamping block 26 retracts it, allowing the connecting pipe 12 to be pulled out in the reverse direction. Compared to existing technologies, this solution eliminates the bolt-fastening structure, automatically locking the connection through elastic deformation during the insertion process. Traditional installation requires tightening four bolts sequentially; this solution requires only a single insertion action, reducing operation time from ten minutes to three seconds. It also eliminates the risk of seal failure due to thread wear, significantly improving connection stability. Through the above technical solution, this application enables rapid disassembly and assembly of air conditioning pipes, allowing operators to complete the installation without carrying wrenches or other tools. The self-locking mechanism during the insertion process effectively prevents loosening of the connection, and the annular support block 20 and the end face of the connector 11 form a double seal, preventing gas leakage. This structure is particularly suitable for the space-constrained environment of an engine compartment, significantly improving maintenance efficiency and reducing labor intensity.

[0023] This application further proposes that a rubber pad 29 is fixedly connected to the side of the movable clamping block 26 away from the limiting spring 25. The rubber pad 29 is a cushioning component made of elastic polymer material, specifically vulcanized rubber or silicone. Its surface can be designed as a flat surface or have an anti-slip texture. This component is fixed to the contact surface of the movable clamping block 26 by vulcanization bonding or mechanical snap-fit, and is used to absorb the impact energy generated by rigid contact. Specifically, when the connector rod 23 is inserted into the through groove 22 of the connecting block 21, the movable clamping block 26 is squeezed into the groove 24 by the inner wall of the through groove 22. At this time, the rubber pad 29 forms surface contact with the inner wall of the through groove 22. The elastic deformation characteristics of the rubber pad 29 ensure that the contact pressure is evenly distributed, avoiding local stress concentration that could cause scratches on the surface of the metal parts. The high coefficient of friction of the rubber material creates a stable static friction force between the movable clamping block 26 and the inner wall of the through groove 22, preventing the connector rod 23 from undergoing axial displacement under vibration. This solution adds a rubber pad 29 to transform rigid contact into elastic contact while maintaining clamping force. This reduces the wear rate of components and utilizes the self-healing properties of rubber materials to maintain a long-term sealing effect. Through the above technical solution, this application effectively alleviates the rigid collision between metal parts during the insertion process, reduces the risk of wear on the contact surface, and at the same time utilizes the high friction characteristics of rubber material to enhance the axial fixation effect of the insertion rod 23 in the connecting block 21, avoiding the loosening of the connection caused by vibration.

[0024] This application further proposes that a sealing gasket 201 is fixedly connected to the side of the annular support block 20 near the connector 11, and the sealing gasket 201 is fixedly fitted on the outer wall of the connecting pipe 12. Among them, the sealing gasket 201 is an annular sealing component made of elastic material, specifically rubber or silicone, whose inner diameter is tightly fitted with the outer wall of the connecting pipe 12 to form a sealing interface. The annular support block 20 is a rigid structural component sleeved on the outside of the connecting pipe 12, specifically made of metal or high-strength plastic, used to provide axial support force for the sealing gasket 201. Specifically, during the insertion of the connecting pipe 12 into the connector 11, the sealing gasket 201 undergoes elastic deformation due to the compression of the inner wall of the connecting hole 13, forming a continuous circumferential sealing contact surface. Since the sealing gasket 201 is pre-installed between the outer wall of the connecting pipe 12 and the annular support block 20, when the connecting pipe 12 is fully inserted into the connector 11, the compression of the sealing gasket 201 is controlled within the elastic deformation range, which avoids excessive compression leading to material fatigue and ensures that the sealing interface can maintain an effective seal even when the internal pressure of the pipeline fluctuates. This solution uses a pre-installed fixed sealing gasket 201 to automatically and evenly press the sealing surface together during the insertion of the connecting pipe 12, achieving a stable sealing effect without additional operation. Through the above technical solution, this application effectively solves the problem of gas leakage caused by the gap between the contact surfaces when the connecting pipe 12 and the connector 11 are installed. The pre-compression deformation of the elastic sealing gasket 201 fills the assembly tolerance, ensuring that the medium inside the air conditioning pipeline can still maintain a sealed state when the pressure changes, while reducing the reliance on manual adjustment of the sealing during the installation process.

[0025] This application further proposes that there are two connecting blocks 21 and two plug-in rods 23. The two connecting blocks 21 are symmetrically arranged on the outer side of the connector 11, and the two plug-in rods 23 are symmetrically arranged on one side of the annular support block 20.

[0026] The connecting block 21 is a block-shaped structure fixed to the outside of the connector 11, which can be achieved by welding or bolting, and provides an insertion channel for the plug-in rod 23. The plug-in rod 23 is a rod-shaped component extending from the annular support block 20, which can be made of metal or high-strength plastic material, and is used to form a plug-in fit with the through groove 22 in the connecting block 21. Symmetrical arrangement means that the two connecting blocks 21 are mirror-distributed on the outside of the connector 11, and the two plug-in rods 23 are mirror-distributed on one side of the annular support block 20. This can be achieved by symmetry along the central axis or by angular symmetry, and is used to balance the force distribution during installation.

[0027] Specifically, when the connecting pipe 12 needs to be connected to the connector 11, the two plug-in rods 23 are respectively inserted into the through slots 22 of the corresponding two connecting blocks 21. During the insertion process, the movable clamping block 26 inside the plug-in rod 23 is squeezed into the groove 24 by the inner wall of the through slot 22, and the limiting spring 25 is compressed; when the plug-in rod 23 is fully inserted, the movable clamping block 26 pops out under the action of the limiting spring 25, and forms a locking with the inner wall of the through slot 22. Since the two sets of plug-in structures are symmetrically distributed, during installation, it is only necessary to align the positions of the two sets of plug-in rods 23 and the connecting blocks 21 and push them in synchronously to complete the bidirectional locking, without the need to tighten multiple bolts one by one.

[0028] This solution simplifies the installation process to a single alignment and pushing action through a symmetrically arranged double-plug structure. At the same time, the bidirectional locking mechanism ensures that the connecting pipe 12 and the connector 11 are subject to balanced constraint forces in both the axial and radial directions, avoiding the misalignment of the sealing surface that may be caused by unilateral tightening.

[0029] Through the above technical solution, this application solves the problem of cumbersome multi-bolt installation steps, simplifying the original multiple rotation operations into a single insertion action. The symmetrically distributed insertion structure enables the connecting pipe 12 and the connector 11 to form a double fixation in the circumference, which not only improves installation efficiency, but also enhances connection stability through mechanical balance design, avoiding the risk of seal failure caused by unilateral force.

[0030] This application further proposes to open a groove 27 on the inner sidewall of the groove 24, and a slider 28 is slidably connected to the inner sidewall of the groove 27. The groove 27 refers to a linear guide structure set on the inner wall of the groove 24, which can be implemented using a T-groove or dovetail groove structure, and is used to limit the movement trajectory of the slider 28. The slider 28 refers to a sliding component that matches the shape of the groove 27, which can be made of metal or wear-resistant plastic material, and is fixedly connected to the movable clamping block 26 to transmit the movement direction of the movable clamping block 26. Specifically, the slide groove 27 extends along the length of the groove 24, and the sliding direction of the slider 28 is consistent with the moving direction of the movable clamping block 26. When the limiting spring 25 is compressed or released, the movable clamping block 26 drives the slider 28 to slide along the slide groove 27. The side wall of the slide groove 27 constrains the lateral displacement of the slider 28, thereby ensuring that the movable clamping block 26 moves only in a preset straight line direction. This application uses the cooperation between the slide groove 27 and the slider 28 to strictly limit the movement trajectory of the movable clamp 26, thereby avoiding sealing failure or loosening of the connection due to offset. Through the above technical solution, this application solves the problem of offset or jamming caused by the lack of a guide structure during the movement of the movable clamping block 26, ensuring that the movable clamping block 26 always moves along a straight trajectory, thereby improving the stability and connection reliability of the disassembly and assembly mechanism 2, and reducing the risk of wear caused by component misalignment.

[0031] This application further proposes that the inner sidewall of the groove 24 is provided with a sliding groove 27, and a slider 28 is slidably connected to the inner sidewall of the sliding groove 27. One side of the slider 28 is fixedly connected to the movable clamping block 26. The groove 27 refers to a linear channel structure set on the inner wall of the groove 24. It can be formed by milling the inner wall of the groove 24 using machining methods, and its extension direction is consistent with the movement trajectory of the movable clamping block 26. The function of the groove 27 is to provide a sliding track for the slider 28, limiting the radial displacement of the movable clamping block 26 during movement. The slider 28 refers to a sliding component that matches the shape of the groove 27. It can be made of metal or high-strength plastic and is fixedly connected to the movable clamping block 26 by fasteners or welding. The function of the slider 28 is to constrain the telescopic movement of the movable clamping block 26 within the linear track of the groove 27, ensuring that the movable clamping block 26 moves only axially. Specifically, when the limiting spring 25 drives the movable clamping block 26 to extend outward from the groove 24, the slider 28 slides synchronously along the track of the slide groove 27, thus restricting the movement direction of the movable clamping block 26 to a straight trajectory. When the movable clamping block 26 retracts into the groove 24 under external pressure, the cooperation between the slider 28 and the slide groove 27 further eliminates any lateral swaying that may occur during the compression process. Through the mechanical guidance of the slide groove 27 and the slider 28, the movement of the movable clamping block 26 within the groove 24 always proceeds along a preset axial direction, avoiding clamping position deviations caused by offset. This solution transforms the free motion of the movable clamping block 26 into controlled linear motion through the sliding engagement of the groove 27 and the slider 28, fundamentally solving the problem of unstable clamping. Through the above technical solution, this application effectively prevents the movable clamping block 26 from shifting when it moves inside the groove 24, ensuring the accuracy and consistency of the clamping action and improving the reliability of the disassembly and assembly mechanism 2 in the pipeline connection process.

[0032] This application further proposes that the side of the connector 11 away from the connecting pipe 12 is fixedly connected to the car air conditioning duct, and the side of the connecting hole 13 is connected to the car air conditioning duct. The connection between the connector 11 and the automotive air conditioning duct, located away from the connecting pipe 12, refers to the rigid connection between the connector 11 and the duct through welding, snap-fitting, or integral molding. This can be achieved using metal welding or injection molding processes, eliminating the assembly gap required by traditional bolt fastening methods and ensuring the positioning accuracy of the connector 11 and the duct. The connection between the connecting hole 13 and the automotive air conditioning duct means that the inner cavity of the connecting hole 13 directly aligns with the inner cavity of the duct. This can be achieved through coaxial alignment or flared insertion, establishing an airflow path and preventing air leakage at the connection point. Specifically, the connection between connector 11 and the air outlet duct is fixed by a rigid mating structure instead of traditional bolt fastening. This eliminates the need to adjust the tightness of multiple bolts during installation; simply align connector 11 with the air outlet duct and fix it in place to complete the assembly. The connection between connecting hole 13 and the air outlet duct is designed to form a continuous airflow channel through direct physical mating, ensuring airtightness without the need for additional seals. This solution eliminates the need for bolt tightening by using a rigid fixed connection and a direct interconnected physical structure, and achieves a sealing effect without relying on sealing rings. Through the above technical solution, this application solves the problem of needing to repeatedly adjust the bolts during the installation of the connector 11 and the air outlet pipe, simplifies the installation steps, and improves the connection stability through the rigid connection and direct connection physical structure, avoiding the risk of leakage caused by loose bolts or aging of the sealing ring.

[0033] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, when the connecting pipe 12 is inserted into the connecting hole 13, it can cause the annular support block 20 to fit against one side of the connector 11, thereby allowing the insertion rod 23 to pass through the through groove 22 of the connecting block 21. This allows the movable clamping block 26 to be squeezed into the groove 24 by the inner wall of the through groove 22. When the movable clamping block 26 loses the squeezing force from the inner wall of the through groove 22, it can be removed from the groove 24 again under the tension of the limiting spring 25. This allows the removed movable clamping block 26 to press the connecting block 21 against the annular support block 20, thus… It can achieve a stable connection between the connecting pipe 12 and the connector 11; at this time, the air generated by the air conditioner can be delivered to the connecting hole 13 of the connector 11 through the air conditioner outlet pipe, so that the air generated by the air conditioner can enter the pipeline body 1 through the connecting pipe 12 and the throttle valve 10, so that the pipeline body 1 can input the air into the interior of the vehicle for temperature regulation; in addition, when it is necessary to disassemble the connecting pipe 12 and the connector 11, the annular support block 20 and the connecting block 21 can be released from the fixing force by pressing the movable clamp 26 into the groove 24, so that the connecting pipe 12 can be pulled out from the connecting hole 13.

[0034] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
