Description
Technical Field
[0001] This utility model relates to the field of automotive piping technology, and in particular to a fastener structure for fixing automotive piping. Background Technology
[0002] Automotive piping refers to the tubular channel system used in automobiles to transport various media. It plays a crucial role in connecting various functional components and ensuring the normal operation of the vehicle. Pipeline connections are divided into flexible hose-to-flexible hose connections, flexible hose-to-rigid hose connections, and rigid hose-to-rigid hose connections.
[0003] When connecting a flexible hose and a rigid pipe, the flexible hose needs to be placed over the rigid pipe and then secured with cable ties or a small-diameter steel ring. To ensure service life, a small-diameter steel ring is often used for fixing and sealing. During installation, the steel ring is placed inside the rigid pipe, and a tool is used to prop it up. Then the flexible hose is placed inside, and the propped steel ring is released. The steel ring will then be placed over the flexible hose, thus sealing the connection between the flexible hose and the rigid pipe.
[0004] However, with long-term use, the liquid flowing through the pipe will repeatedly impact the position of the hose clamped by the steel ring, which will cause slight displacement of the steel ring. Therefore, the steel ring needs to be inspected and adjusted regularly. Therefore, this application proposes a fastener structure for fixing automotive pipelines. Utility Model Content
[0005] The purpose of this invention is to address the problem in the prior art where, under long-term use, the liquid flowing through the pipe repeatedly impacts the hose clamped by the steel ring, causing slight displacement of the steel ring. Therefore, it is necessary to periodically inspect and adjust the steel ring. This invention proposes a fastener structure for fixing automotive pipelines.
[0006] The technical solution of this utility model is: a fastener structure for fixing automotive pipelines, including a sealing ring, an adjustment groove is provided inside the sealing ring, a first adjustment slot is provided on one side of the sealing ring, the first adjustment slot is connected to the adjustment groove, and a second adjustment slot is provided on the sealing ring away from the first adjustment slot, the second adjustment slot is connected to the adjustment groove.
[0007] A spring is fixedly connected inside the sealing band. There are three sets of springs arranged in a circumferential array. A positioning plate is fixedly connected to the end of the spring away from the sealing band. The positioning plate is inclined. An anti-detachment block is fixedly connected to the side of the positioning plate away from the spring.
[0008] Optionally, the anti-detachment block is arranged in an anti-tilt position relative to the positioning plate, and there are multiple sets of anti-detachment blocks arranged in a linear array on the side of the positioning plate away from the spring.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1-3 As shown, the present invention proposes a fastener structure for fixing automotive pipelines, including a sealing clamp 1. An adjustment groove 2 is provided inside the sealing clamp 1. A first adjustment slot 16 is provided on one side of the sealing clamp 1, communicating with the adjustment groove 2. A second adjustment slot 17 is provided on the sealing clamp 1 away from the first adjustment slot 16. Through the cooperation of the second adjustment slot 17 and the first adjustment slot 16, the inner diameter of the sealing clamp 1 can be expanded by relying on the adjustment groove 2. A spring 12 is fixedly connected inside the sealing clamp 1. Three sets of springs 12 are arranged in a circumferential array. A positioning plate 11 is fixedly connected to the end of the spring 12 away from the sealing clamp 1. The spring 12 can push the positioning plate 11 to tilt, thus making one end of the positioning plate 11 higher than the other, resulting in an inclined positioning plate 11. An anti-detachment block 14 is fixedly connected to the side of the positioning plate 11 away from the spring 12. The anti-detachment block 14 can tightly engage with the outside of the hose, thereby sealing the connection between the hose and the rigid pipe and increasing friction.
[0024] like Figure 1 and Figure 5 As shown, the anti-detachment block 14 and the positioning plate 11 are arranged in an anti-tilt shape. There are multiple sets of anti-detachment blocks 14 arranged in a linear array on the side of the positioning plate 11 away from the spring 12. The anti-tilt structure of the positioning plate 11 can increase the friction. The positioning plate 11 is rotatably connected to the inside of the positioning plate 11. The two ends of the support shaft 13 are fixedly connected to the support plates 15. The support shaft 13 can be supported by the support plates 15, allowing the positioning plate 11 to rotate outside the support shaft 13. The support plates 15 are fixedly connected inside the sealing ring 1. The outside of the sealing ring 1 is fixedly connected to the adjustment plate 3 near the first adjustment seam 16. The outside of the sealing ring 1 is fixedly connected to the compression plate 10 near the second adjustment seam 17. Through the cooperation of the adjustment plate 3 and the compression plate 10, the inner diameter of the sealing ring 1 can be expanded.
[0025] like Figure 1 , Figure 3 and Figure 4As shown, the adjusting plate 3 and the extrusion plate 10 are equipped with screws 4 inside. The rotation of screws 4 can drive the adjusting plate 3 and screws 4 to move closer to each other, thereby expanding the inner diameter of the sealing ring 1. The extrusion plate 10 is equipped with a positioning component near the screws 4. The positioning component includes a slot 5, which is opened on one side of the extrusion plate 10. An insert plate 6 is slidably connected inside the slot 5. Screws 4 can rotate inside the insert plate 6. The insert plate 6 is located outside the screws 4. The insert plate 6 has a threaded groove 7 inside. Screws 4 are rotatably connected to the threaded groove 7. The insert plate 6 rotates outside the screws 4 by relying on the threaded groove 7, thereby bringing the adjusting plate 3 and the extrusion plate 10 closer to each other. The insert plate 6 has a disassembly port 8 near the threaded groove 7. The insert plate 6 can be pulled out from inside the slot 5 through the disassembly port 8. A pull-out plate 9 is fixedly connected to one side of the insert plate 6. The pull-out plate 9 abuts against one side of the extrusion plate 10. The pull-out plate 9 facilitates the movement and control of the insert plate 6.
[0026] In this embodiment, during use, the sealing clamp 1 is first put on the outside of the rigid pipe, and then the flexible tube is put on the end of the rigid pipe. The insert plate 6 is inserted into the slot 5 using the pull plate 9, and then the screw 4 is inserted through the inside of the adjusting plate 3. At this time, the thread position of the screw 4 can be aligned with the thread groove 7. When the screw 4 is rotated, the screw 4 will rotate along the thread groove 7. In this way, the screw 4 will drive the adjusting plate 3 to move closer to the extrusion plate 10, so that the screw 4 and the extrusion plate 10 can expand the inner diameter of the sealing clamp 1.
[0027] After the inner diameter of the sealing clamp 1 is expanded, the sealing clamp 1 is placed at the junction of the hose and the rigid pipe. At this time, the insert plate 6 can be pulled out from the slot 5 by the pull plate 9. The disassembly port 8 of the insert plate 6 will not be blocked by the screw 4. When the insert plate 6 is pulled out, the screw 4 loses the squeezing force on the adjusting plate 3. The elasticity of the sealing clamp 1 will allow the sealing clamp 1 to return to its original inner diameter, so that the sealing clamp 1 is clamped on the outside of the hose, thereby sealing the connection between the hose and the rigid pipe.
[0028] During installation, the positioning plate 11 that fixes the spring 12 needs to face the side where the hose and the rigid pipe are connected. This way, when liquid impacts, even if liquid enters the area between the hose and the rigid pipe, the anti-dislodgement block 14 will be tightly embedded in the outside of the hose, thereby increasing the force at the connection between the hose and the rigid pipe and ensuring the tightness of the connection between the hose and the rigid pipe.
[0029] The positioning plate 11 is conveniently positioned by the support shaft 13 supported by the support plate 15, so that when the positioning plate 11 changes angle, it will rotate along the outside of the support shaft 13, thus ensuring the smooth effect of the positioning plate 11 when changing angle.
[0030] During prolonged use, the sealing clamp 1 may inevitably shift. In this case, the insert plate 6 can be inserted into the slot 5, and the screw 4 can be inserted from the position of the adjusting plate 3. Repeating the above installation operation can adjust the position of the sealing clamp 1.
[0031] It should be noted that this device uses a screw 4 and a insert plate 6 working together, allowing the screw 4 to move within the threaded groove 7 inside the insert plate 6, thereby bringing the adjusting plate 3 and the pressing plate 10 closer together. This expands the inner diameter of the sealing clamp 1. After the insert plate 6 is removed, the inner diameter of the sealing clamp 1 returns to its original position, allowing for quick adjustment of the sealing clamp 1's position. Furthermore, the structure of the positioning plate 11 and the anti-detachment block 14 increases the clamping force at the connection between the hose and the rigid pipe, avoiding the inconvenience of operating a single sealing clamp 1 without specialized tools, and the problem that a single sealing clamp 1 has low friction and requires regular maintenance and adjustment. This improves the convenience of adjusting the sealing clamp 1 and the clamping force of the sealing clamp 1 on the hose and the rigid pipe.
[0032] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
