Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a quick-release air intake pipe. Background Technology
[0002] The intake manifold is a key component of the engine's intake system. Its core function is to distribute clean air filtered by the air filter, or the mixture of fuel and air, evenly and stably to each cylinder of the engine, providing sufficient and adequate intake air for combustion in the cylinders, which directly affects the engine's power output, fuel economy, and emissions performance.
[0003] Due to the dense internal components of the engine compartment, the intake pipe connector is often surrounded by the cylinder block, wiring harness and other components, resulting in a small space available for disassembly. This not only makes it difficult to accommodate the complete movement trajectory of tools such as wrenches and sockets, but also requires special irregular tools to reach some deep cavities or corner connectors. Conventional tools cannot exert force efficiently. At the same time, the limited space also hinders the pre-treatment of components before disassembly, making it impossible to fully prepare for disassembly, which further increases the difficulty of disassembly.
[0004] Therefore, it is necessary to invent a quick-release intake pipe to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a quick-release intake pipe to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release air intake pipe, comprising an air intake pipe body, both ends of which are fixedly installed with sleeves having slits on their sides, a mounting plate fixedly connected to one side of the sleeves, a cover plate inserted into the mounting plate, the mounting plate and the cover plate combined to form a joint, the ends of the sleeves and the cover plate are provided with sealing strips for improving sealing performance, a plug block that is hinged to one side of the cover plate and inserted into the mounting plate, the inner side of the end of the plug block having symmetrically opened second insertion holes, a side plate fixedly installed on the other side of the cover plate, the inner side of the end of the side plate having symmetrically opened first insertion holes.
[0007] Preferably, the inner circumferential surfaces of the sleeve and the cover plate are provided with arc-shaped grooves adapted to the sealing strip and cavities communicating with the arc-shaped grooves, and the outer circumferential sides of the sealing strip are symmetrically fixedly connected with extrusion blocks that slide with the inner cavities of the sleeve and the cover plate.
[0008] Preferably, a limiting rod is fixedly connected to the middle of the end of the extrusion block, which movably passes through the sleeve and the cover plate. A first compression spring with one end abutting against the extrusion block is sleeved on the outer peripheral surface of the limiting rod, and the other ends of the two first compression springs abut against the sleeve and the cover plate respectively.
[0009] Preferably, the end of the sleeve is provided with an arc-shaped protrusion, and one end of the cover plate is provided with an arc-shaped groove that matches the arc-shaped protrusion.
[0010] Preferably, the sleeve is provided with fixing components on both sides near the sealing strip. The fixing components include a fixing frame fixedly connected to the sleeve, a crossbar fixedly installed inside the fixing frame, a limit plate symmetrically slidably installed inside the fixing frame, and a limit hole opened on the side of the limit plate.
[0011] Preferably, a crossbar that movably passes through the limiting hole is fixedly installed inside the fixed frame, and a second compression spring is sleeved on the outer peripheral surface of the crossbar, with its two ends respectively abutting against the inner sides of the two limiting plates.
[0012] Preferably, the outer peripheral sides of the two limiting plates are fixed with inserts, the inserts being located on the sealing strip and connected to the second insertion hole, and the inserts being located on the other side of the sealing strip and connected to the first insertion hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The crossbar, second compression spring, limiting plate, and insert post in the fixing assembly work together to provide a stable sliding track for the limiting plate, allowing it to slide flexibly inward along the crossbar without the need for tools such as wrenches or sockets. At the same time, the elasticity of the second compression spring allows the limiting plate to have the functions of pressing to unlock and spring-lock. During disassembly, simply pressing the limiting plate inward manually will cause the insert post to disengage from the first and second insertion holes. The fixing and release operation can be completed without special tools, and unlocking can be achieved with only limited hand movements. This effectively solves the problem of difficulty in positioning and applying force with tools in confined spaces, thereby reducing the difficulty of disassembling the air intake pipe interface.
[0014] The sealing function of the arc-shaped groove sealing strip is automatically achieved through the elastic contact between the extrusion block and the first compression spring. There is no need to manually adjust the position of the sealing strip in a confined space or perform additional sealing pretreatment. Furthermore, the first compression spring can dynamically compensate for the wear gap of the sealing strip, ensuring long-term sealing stability and thus improving the connection sealing performance of the interface.

[0020] 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.
[0021] This utility model provides, for example Figures 1-4 The quick-release air intake pipe shown includes an air intake pipe body 1. Both ends of the air intake pipe body 1 are fixedly installed with sleeves 2 with slits on the sides. A mounting plate 201 is fixedly connected to one side of the sleeve 2. A cover plate 7 is inserted into the mounting plate 201. The mounting plate 201 and the cover plate 7 are combined to form a joint. Both the ends of the sleeve 2 and the cover plate 7 are provided with sealing strips 3 to improve sealing. A plug block 10 that is inserted into the mounting plate 201 is hinged to one side of the cover plate 7. A second insertion hole 1001 is symmetrically opened on the inner side of the end of the plug block 10. A side plate 8 is fixedly installed on the other side of the cover plate 7. A first insertion hole 9 is symmetrically opened on the inner side of the end of the side plate 8.
[0022] The intake manifold body 1, as the core load-bearing component, provides a basic intake channel for the engine cylinders. The cut-out design on the side of the sleeve 2 facilitates precise docking and fixation with both ends of the intake manifold body 1, while reserving space for the subsequent assembly of the mounting plate 201. The mounting plate 201 and the cover plate 7 are inserted to form a joint, realizing the connection between the intake manifold and other intake components of the engine. The insertion structure facilitates later disassembly and maintenance. The sealing strip 3 can fill the gap between the sleeve 2 and the end of the cover plate 7 to prevent air leakage during intake, ensure stable intake volume, and avoid affecting engine power output and fuel economy. The insert block 10 is inserted into the mounting plate 201, and with the second insertion hole 1001, it realizes quick positioning and fixation of one side of the cover plate 7 and the mounting plate 201, reducing assembly deviation. The side plate 8 cooperates with the first insertion hole 9 to provide a fixed support point for the other side of the cover plate 7, ensuring the stability of the joint structure after the cover plate 7 and the mounting plate 201 are combined.
[0023] The inner circumferential surfaces of the sleeve 2 and the cover plate 7 are provided with arc-shaped grooves that fit the sealing strip 3, and cavities that communicate with the arc-shaped grooves. The outer circumferential sides of the sealing strip 3 are symmetrically fixedly connected with extrusion blocks 4 that slide with the inner cavities of the sleeve 2 and the cover plate 7. The arc-shaped grooves are used to accurately accommodate the sealing strip 3, preventing the sealing strip 3 from shifting due to airflow impact during air intake, and ensuring a stable sealing position. The cavity provides sliding space for the extrusion blocks 4, allowing the extrusion blocks 4 to move with the deformation of the sealing strip 3 or during assembly operations. The extrusion blocks 4 slide with the cavity, which on the one hand can push the sealing strip 3 to fit against the inner wall of the arc-shaped groove during assembly, enhancing the sealing effect, and on the other hand can limit the excessive deformation of the sealing strip 3, avoiding damage to the sealing strip 3 due to long-term use and extending its service life.
[0024] A limiting rod 5 is fixedly connected to the middle of the end of the extrusion block 4, which movably passes through the sleeve 2 and the cover plate 7. A first compression spring 6 with one end abutting against the extrusion block 4 is sleeved on the outer circumferential surface of the limiting rod 5. The other ends of the two first compression springs 6 abut against the sleeve 2 and the cover plate 7 respectively. The limiting rod 5 movably passes through the sleeve 2 and the cover plate 7, which can limit the sliding direction of the extrusion block 4, prevent the extrusion block 4 from shifting in the cavity, and ensure that it always applies pressure to the sealing strip 3 along the sealing direction. The first compression spring 6 continuously applies a resisting force to the extrusion block 4 through its own elastic deformation, so that the extrusion block 4 always sticks tightly to the sealing strip 3. Even if the sealing strip 3 is slightly worn after long-term use, the elastic force of the spring can push the extrusion block 4 to compensate for the wear gap and maintain a stable sealing effect. The limiting rod 5 and the first compression spring 6 cooperate to form an elastic limiting structure, which avoids the extrusion block 4 from applying too much pressure to the sealing strip 3, causing the sealing strip 3 to deform and be damaged. At the same time, it prevents the pressure from being too low, which affects the sealing performance, and achieves a dynamic balance of sealing pressure.
[0025] The end of the sleeve 2 is provided with an arc-shaped protrusion 202, and one end of the cover plate 7 is provided with an arc-shaped groove 701 that matches the arc-shaped protrusion 202. The arc-shaped protrusion 202 and the arc-shaped groove 701 work together to reduce the size of the gap at the interface when the sleeve 2 and the cover plate 7 are connected to improve the sealing performance.
[0026] Fixing components 11 are provided on both sides of the sleeve 2 near the sealing strip 3. The fixing components 11 include a fixing frame 1101 fixedly connected to the sleeve 2. A crossbar 1102 is fixedly installed inside the fixing frame 1101. A limit plate 1104 is symmetrically slidably installed inside the fixing frame 1101. Limiting holes 1105 are opened on the side of the limit plate 1104. The fixing components 11 are used to connect and fix the sleeve 2 and the cover plate 7. The fixing frame 1101 serves as the basic frame of the fixing components 11, providing installation support for the crossbar 1102 and the limit plate 1104, ensuring that the components are assembled in an orderly manner. The crossbar 1102 is fixedly installed on the sleeve 2. Inside the fixed frame 1101, on the one hand, a sliding track is provided for the limiting plate 1104 to restrict the movement direction of the limiting plate 1104. On the other hand, the rigidity of the fixed frame 1101 is used to enhance the structural strength of the fixed frame 1101 and prevent the fixed frame 1101 from deforming under force. The limiting plate 1104 is symmetrically slidably installed and its position can be adjusted by sliding in opposite directions to adapt to the fixing requirements of different assembly states. The limiting hole 1105 cooperates with the crossbar 1102 to ensure that the limiting plate 1104 slides stably along the crossbar 1102, avoids the limiting plate 1104 tilting or getting stuck during the sliding process, and ensures the smooth operation of the fixing component 11.
[0027] A crossbar 1102, which movably passes through the limiting hole 1105, is fixedly installed inside the fixed frame 1101. A second compression spring 1103, with its two ends respectively abutting against the inner surfaces of the two limiting plates 1104, is sleeved on the outer circumferential surface of the crossbar 1102. The crossbar 1102 movably passes through the limiting hole 1105, further enhancing the guiding effect on the limiting plates 1104, ensuring the precise sliding trajectory of the limiting plates 1104 and preventing deviation. The two ends of the second compression spring 1103 abut against the two limiting plates 1104, and through elasticity... The force pushes the two limiting plates 1104 to maintain an outward expansion trend. When the cover plate 7 and the sleeve 2 are assembled in place, the limiting plate 1104 can automatically lock the corresponding structure of the cover plate 7 under the action of the spring force to achieve quick fixation. The elastic characteristics of the spring can compensate for slight dimensional deviations during the assembly process. Even if there is a slight error in the assembly position of the cover plate 7 and the sleeve 2, the second compression spring 1103 can adjust the position of the limiting plate 1104 by deformation to ensure the fixing effect and avoid damage to the components caused by rigid fixation.
[0028] Two limiting plates 1104 are fixed with inserts 1106 on their outer sides. The inserts 1106 are located on the sealing strip 3 and are inserted into the second insertion hole 1001. The inserts 1106 are located on the other side of the sealing strip 3 and are inserted into the first insertion hole 9. The inserts 1106 are inserted into the second insertion hole 1001 and the first insertion hole 9 respectively, which directly realizes the mechanical fixation of the limiting plates 1104 and the cover plate 7, and firmly locks the cover plate 7 on the mounting plate 201 to prevent relative loosening at the joint. The insertion structure is easy to disassemble. During later maintenance, the limiting plates 1104 can be pushed inward to disengage the inserts 1106 from the insertion holes and the cover plate 7 can be removed, which solves the problem of difficult disassembly in a narrow space.
[0029] The working principle of this utility model is as follows: During assembly, the sleeve 2 is first placed at the interface of the air intake pipe. The arc groove 701 at one end of the cover plate 7 is aligned with the arc protrusion 202 at the end of the sleeve 2. The arc structure plays a guiding role, quickly correcting the relative position of the cover plate 7 and the sleeve 2, and reducing assembly deviation. At the same time, the insert block 10 on one side of the cover plate 7 is inserted into the corresponding slot of the mounting plate 201, and the side plate 8 on the other side is attached to the side of the mounting plate 201 to complete the initial splicing of the joint and form a closed air intake joint fixed at the interface.
[0030] The crossbar 1102 inside the fixed frame 1101 provides a stable sliding track for the limiting plate 1104. In the initial state, the second compression spring 1103 generates an outward elastic force due to natural deformation, pushing the two limiting plates 1104 to expand outward along the crossbar 1102. When the cover plate 7 and the mounting plate 201 are in place, the insert post 1106 on the outer periphery of the limiting plate 1104 automatically inserts into the second insertion hole 1001 of the insert block 10 and the first insertion hole 9 of the side plate 8 under the action of the spring force, realizing the mechanical locking of the limiting plate 1104 and the cover plate 7. At this time, the cover plate 7 is firmly fixed on the mounting plate 201, and the elastic characteristics of the second compression spring 1103 can compensate for slight dimensional errors in the assembly, avoid rigid fixation that could damage the components, and ensure the stability of the joint structure.
[0031] The sleeve 2 and cover plate 7 are fitted together by the arc-shaped protrusion 202 and arc-shaped groove 701, which increases the contact area between the two and significantly reduces the gap size at the interface, forming the first line of sealing defense and reducing the risk of air leakage from the interface gap. This lays the foundation for subsequent precision sealing. The arc-shaped groove on the inner circumference of the sleeve 2 and cover plate 7 accurately accommodates the sealing strip 3. The extrusion block 4 on the outer circumference of the sealing strip 3 is continuously subjected to force under the action of the first compression spring 6. One end of the first compression spring 6 abuts against the sleeve 2 or cover plate 7, and the other end applies a stable abutment force to the extrusion block 4, pushing the extrusion block 4 to press tightly against the sealing strip 3, so that the sealing strip 3 fits tightly against the inner wall of the arc-shaped groove and fills the tiny gaps. If the sealing strip 3 is slightly worn after long-term use, the first compression spring 6 can push the extrusion block 4 forward through elastic deformation to compensate for the wear gap and maintain stable sealing pressure. The limit rod 5 restricts the sliding direction of the extrusion block 4 to prevent it from deviating and causing sealing failure, thus achieving dynamic balance of sealing performance, ensuring stable delivery of intake air to the engine cylinder, and guaranteeing engine power output and fuel economy.
[0032] When disassembly and maintenance are required, simply press the limiting plates 1104 of the two fixing components 11 inward. The limiting plates 1104 slide along the crossbar 1102 towards the middle, compressing the second compression spring 1103, causing the insert 1106 to disengage from the first insertion hole 9, releasing the fixing constraint of the cover plate 7. The cover plate 7 is then flipped over, making it easy to remove the sleeve 2 from the connector. When space is still limited, press the other limiting plate 1104 to cause the insert 1106 to disengage from the second insertion hole 1001, causing the insert block 10 hinged on one side of the cover plate 7 to disengage from the slot of the mounting plate 201. This allows the cover plate 7 to be separated from the mounting plate 201, completing the disassembly of the intake pipe connector. The entire process does not require complex tools and can be quickly disassembled by manual operation, effectively solving the problem of difficult disassembly in the confined space of the engine compartment and improving maintenance efficiency.
