Description

Technical Field

[0001] The present invention relates to the technical field of automobile pipeline joints, in particular to a double-sealed automobile pipeline connection joint. Background Art

[0002] Automobile pipe joints are parts that connect automobile pipes or install pipes on automobile components. They are the general term for connectors that can be installed and removed in automobile fluid passages. Mechanical engineering has a close relationship with automobile pipe joints. Mechanical engineering plays a vital role in the design, manufacture and maintenance of automobile pipe joints. There are many types of automobile pipe joints, and each type has its specific application scenarios.

[0003] For example, the utility model patent with the authorization announcement number CN220016435U discloses a sealing joint for connecting automobile pipelines, including a connecting body, end caps located at both ends of the connecting body, and a spherical sealing ring located between the end cap and the connecting body; the connecting body, the end cap and the spherical sealing ring are all formed with a channel for the pipeline to pass through; the end cap is detachably connected to the connecting body; both ends of the connecting body are formed with a connecting cavity connected to the end cap, and one end of the end cap is formed with a connecting column that matches the connecting cavity. The entire connection structure is simple, and it is very efficient and convenient when installing the connecting pipeline, and there is no need to pre-treat the pipeline, so that the connection and sealing of pipelines with smaller diameters can be achieved.

[0004] However, the above technical solution still has some shortcomings. Combining the existing solution and the actual production and processing, the sealing of the current joint after connection is general. Poor sealing will lead to poor airtightness, which will affect the overall performance of the car. At the same time, the joint cannot achieve quick-plug connection during the connection process, which will greatly reduce the efficiency of installation and connection. In addition, after the joint is connected, the joint will collide during driving, which will cause poor contact of the joint, affecting the normal operation of the electronic system of the car.

[0005] Therefore, we propose a double-sealed automobile pipeline connection joint to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a double-sealed automobile pipeline connection joint to solve the automobile pipeline connection joint proposed in the above-mentioned background technology, combining the existing scheme and the actual production and processing use, the current speed of joint butt installation, the sealing of the joint after butt connection, and the problem that the joint may be hit during the driving of the car.

[0015] Preferably, second fixing blocks are fixedly installed on the front sides of the upper and lower sides of the middle part of the fixing ring, and a first fixing block is snap-connected to the rear side inside the second fixing block. Moreover, the first fixing block is fixedly installed on the rear sides of the upper and lower sides of the middle part of the fixing ring.

[0016] Preferably, a sealing ring is provided inside the fixing ring, and the sealing ring is closely attached to the outer side of the connection between the first flange and the second flange.

[0017] Preferably, a threaded rod is threadedly connected inside the first fixing block and the second fixing block, and a torsion spring is provided on the outer side of the threaded rod. Moreover, the torsion spring is closely attached to the outer side of the second fixing block.

Moreover, a connection bar is rotatably connected to the left side inside the connector, and the right side inside the connector is fixedly connected to the connection bar through a second bolt.

[0019] Preferably, a bracket is fixedly connected below the connection bar, and a buckle is snap-connected below the bracket. Moreover, the buckles are arranged at equal angles inside a rubber cushion block. Moreover, mounting blocks are fixedly installed on the left and right sides below the rubber cushion block, and mounting holes are opened inside the mounting blocks.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: for this double-sealed automotive pipeline connection joint, by setting a double-sealed mechanism, the sealing performance of the pipeline joint connection is greatly enhanced, ensuring the stable operation of the automotive system. At the same time, a quick-insert mechanism is set, enabling rapid installation and connection during joint docking, greatly improving the installation efficiency. In addition, a collision-proof mechanism is set to fix the position of the joint after docking, effectively ensuring that during the operation of the vehicle, the joint will not be damaged due to vibration and collision;

[0021] 1. A first joint, a second joint, a notch, and a pushing block are provided. By arranging a connecting block inside the first joint and a moving ring outside the first joint, clamping blocks and first springs are symmetrically installed up and down in the middle of the moving ring. The clamping blocks are arranged inside the first springs, and the outer sides of the first springs are fixedly connected to the moving ring. Due to the elasticity of the first springs, the second joint can be inserted into the first joint. Since a notch is opened inside the second joint, and pushing blocks are installed on the upper and lower sides in the middle of the notch, when the second joint enters the first joint, the pushing blocks will come into contact with the clamping blocks, pushing the clamping blocks outward. At this time, the first springs will contract. In addition, clamping grooves are also opened on the upper and lower sides inside the second joint. When the clamping grooves symmetrically arranged up and down inside the second joint slide to the clamping blocks of the first joint, the first springs will rebound, pushing the clamping blocks to move inward to engage with the clamping grooves. At this time, the connecting block and the notch will also be engaged. Moreover, multiple connecting blocks and notches are arranged at equal distances, further strengthening the stability of the insertion of the first joint and the second joint;

[0022] 2. A moving ring, a first bolt, a support block, and a second spring are provided. After the second joint is inserted into the first joint, it cannot be quickly disassembled. That is, since the first bolt is tightened and fixed on the outer side of the moving ring, and a support block is arranged on the outer side of the moving ring, and a second spring is installed inside the support block. The second spring also has elasticity. The fixed first bolt can be unscrewed and pulled out. Then the second spring will rebound, pushing the moving ring to move upward and downward. That is, the moving ring can pull the clamping blocks and the first springs installed inside it to move together, enabling the clamping blocks to disengage from the clamping grooves arranged inside the second joint, and the second joint can be pulled out of the first joint for separation;

[0023] 3. A first flange, a clamping opening, a second flange, and a clamping pin are provided. By providing a first flange on the outer side of the interface of the first joint and a second flange on the outer side of the interface of the second joint, since the clamping pins are installed at equal angles on the outer side of the second flange and the clamping openings are opened at equal angles inside the first flange, that is, when the first joint and the second joint are inserted, the clamping pins will be clamped and connected with the clamping openings, that is, the clamping openings and the second flange will be firmly attached together. By providing a sealing piece inside the first flange, the sealing performance after the connection between the clamping opening and the second flange can be enhanced;

[0024] 4. A fixing ring, a sealing ring, and a first fixing block are provided. After the second flange and the first flange are attached, the fixing ring can be attached to the front and rear sides of the connection between the first flange and the second flange. Since a second fixing block is installed on the front side above the middle of the fixing ring and a first fixing block is installed on the rear side of the middle of the fixing ring, that is, when the fixing ring is closely attached to the outer side of the connection between the first flange and the second flange, the first fixing block and the second fixing block will be closely attached. At this time, the torsion spring can be inserted outside the threaded rod, and then the threaded rod is inserted into the first fixing block and the second fixing block and tightened to fix, so as to limit the position of the fixing ring. At this time, the sealing ring installed inside the fixing ring will be closely attached to the outside of the connection between the first flange and the second flange, which can further enhance the sealing performance of the connection between the first flange and the second flange, that is, a double-sealing mechanism can ensure the stable operation of the automotive system;

[0025] 5. A connecting piece, a connecting bar, a bracket, and a buckle are provided. By installing connecting pieces on the outer sides of both the first flange and the second flange, and rotatably installing a connecting bar inside the connecting piece installed on the outer side of the first flange.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9 , the present invention provides a technical solution:

[0038] Embodiment 1: To solve the problems existing in the prior art, therefore, through the following technical solutions in this embodiment, a double-sealed automotive pipeline connection joint includes:

[0039] The first connector 1, a quick-insert mechanism, is provided at the connection between the first connector 1 and the second connector 2. The second connector 2 is inserted inside the first connector 1, and the second connector 2 can be quickly inserted and set inside the first connector 1; a double-sealing mechanism is provided on the outer side of the interfaces of the first connector 1 and the second connector 2. The first flange 13 is installed on the outer side of the interface of the first connector 1, and the second flange 15 is installed on the outer side of the interface of the second connector 2. The first flange 13 and the second flange 15 can be quickly snap-connected. A sealing piece 17 is provided inside the first flange 13, and fixing rings 18 are symmetrically arranged on the front and back of the outer side after the first flange 13 and the second flange 15 are snap-connected. A sealing ring 19 is provided inside the fixing ring 18; an anti-collision mechanism is provided on the outer side of the first flange 13 and the second flange 15. After the first connector 1 and the second connector 2 are hermetically connected, the positions of the first connector 1 and the second connector 2 can be fixed;

[0040] In the above technical solution, as Figure 3 and Figure 4 shown, by providing push blocks 4 on the upper and lower sides of the outside of the interface of the second connector 2, when the second connector 2 is inserted inside the first connector 1, the push blocks 4 will come into contact with the blocks 7 symmetrically arranged on the upper and lower sides of the middle of the moving ring 9. Since the first spring 8 is fixedly installed on the outer side of the block 7 and the outer side of the first spring 8 is fixedly supported by the moving ring 9, that is, when the push block 4 comes into contact with the block 7, the block 7 will be pushed outward. At this time, the first spring 8 will expand and contract. When the card slots 5 symmetrically opened on the upper and lower sides of the middle of the second connector 2 slide to the position of the block 7, the first spring 8 will rebound and push the block 7 to move inward to engage with the card slots 5, so that the second connector 2 and the first connector 1 can be quickly and firmly snapped together;

[0041] Furthermore, in this technical solution, after the first connector 1 and the second connector 2 are connected, it is difficult to quickly disassemble them. That is, on the outer side of the first connector 1, the outer side of the moving ring 9 is tightened and fixed by setting the first bolt 10, so that the moving ring 9 can be firmly installed on the outer side of the first connector 1. The inner side of the moving ring 9 is closely attached to the outer side of the first spring 8. In addition, a support block 11 is provided on the outer side of the moving ring 9, and a second spring 12 is provided inside the support block 11. When the fixed first bolt 10 is unscrewed and pulled out of the inside of the moving ring 9, that is, the moving ring 9 will be separated up and down. At this time, the second spring 12 will rebound and push the moving ring 9 to move outward, and the first spring 8 installed inside the moving ring 9 will pull the block 7 to move outward, so that the block 7 can be disengaged from the card slot 5, which is convenient for the second connector 2 to be disengaged from the first connector 1.

[0042] At the same time, in this technical solution, as Figures 5-8As shown, a first flange 13 is installed on the outer side of the interface of the first joint 1, and a second flange 15 is installed on the outer interface of the second joint 2. Engagement openings 14 are equiangularly formed inside the first flange 13, and engagement pins 16 are equiangularly installed on the outer side of the second flange 15. After the first joint 1 and the second joint 2 are plugged together, the engagement pins 16 and the engagement openings 14 will be engaged and connected. At this time, the first flange 13 and the second flange 15 will be closely attached together. In addition, a sealing sheet 17 is arranged inside the first flange 13. When the first flange 13 and the second flange 15 are closely attached, the sealing sheet 17 will be arranged between the connections of the first flange 13 and the second flange 15, effectively increasing the sealing performance of the connection between the first flange 13 and the second flange 15;

[0043] After the second flange 15 is connected to the first flange 13, the fixing ring 18 can be closely attached to the outside of the interfaces of the second flange 15 and the first flange 13 from the front and back. Since a sealing ring 19 is arranged inside the fixing ring 18, and second fixing blocks 21 are installed in the front of the upper and lower sides of the middle of the fixing ring 18, and first fixing blocks 20 are installed in the back of the upper and lower sides of the middle of the fixing ring 18. That is, after the fixing ring 18 is attached to the interfaces of the second flange 15 and the first flange 13 from the front and back, the first fixing blocks 20 and the second fixing blocks 21 will be firmly engaged and connected. At this time, the threaded rod 22 can be inserted into the first fixing block 20 and the second fixing block 21 and tightened. At the same time, a torsion spring 23 is arranged on the outer side of the threaded rod 22. When the threaded rod 22 tightens and fixes the first fixing block 20 and the second fixing block 21, the torsion spring 23 will be attached to the outer side of the second fixing block 21, making the fixing ring 18 and the sealing ring 19 firmly installed on the outer side of the connection of the second flange 15 and the first flange 13. The sealing ring 19 will be closely attached to the interfaces of the first flange 13 and the second flange 15, which can further improve the sealing performance of the connection between the second flange 15 and the first flange 13. The setting of the torsion spring 23 can increase the bearing capacity of the connection between the flanges and absorb vibration and impact energy;

[0044] That is, a double sealing performance is set, greatly enhancing the sealing performance of the connection between the automotive pipeline joints and effectively ensuring the stable operation of the automotive system.

[0045] Adopt as Figures 8-9In the technical solution shown, a connecting member 24 is installed outside the first flange 13, and a connecting bar 25 is rotatably arranged inside the connecting member 24. After the second flange 15 is snap-connected to the first flange 13, one end of the connecting bar 25 can be rotated into the connecting member 24 installed outside the second flange 15, and then the second bolt 30 is inserted into the connecting member 24 and the connecting bar 25 and tightened to fix them. In this way, the connecting bar 25 is fixedly connected to the inner side of the connecting member 24. At the same time, a bracket 26 is installed below the connecting bar 25, and the bracket 26 is snap-connected to a buckle 27 below it. At the same time, a rubber cushion block 28 is installed below the buckle 27, that is, mounting blocks 29 are symmetrically installed on the left and right sides below the rubber cushion block 28. That is, the mounting blocks 29 can be fixed to a fixed object by rivets, which effectively fixes the positions of the first joint 1 and the second joint 2 after insertion, effectively ensuring that the joints do not move during the operation of the vehicle, and thus avoiding the occurrence of collisions.

[0046] Embodiment 2: On the basis of Embodiment 1 of the present invention, the Figure 4 technical solution shown further discloses that connecting blocks 6 are installed at equal angles inside the first joint 1, and notches 3 are opened at equal angles on the outer side of the interface of the second joint 2. At the same time, the size of the connecting blocks 6 is the same as that of the notches 3. When the second joint 2 is inserted into the first joint 1, the notches 3 will be snap-connected to the connecting blocks 6, enabling the first joint 1 and the second joint 2 to be quickly and firmly snap-connected together. Since a plurality of notches 3 and connecting blocks 6 are provided at equal angles, the firmness of the snap connection between the first joint 1 and the second joint 2 is increased.

[0047] This is the entire working process of a double-sealed automotive pipeline connection joint. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
