Description

Technical Field

[0001] This utility model relates to the field of hump pipe installation technology, and in particular to a tool-free connection clip for hump pipe installation. Background Technology

[0002] Hump ​​hoses are corrugated flexible hoses commonly used in automotive engine intake or exhaust systems. Their walls have a hump-shaped convex structure, providing good flexibility and extensibility while ensuring pipe strength and sealing. Hump hoses typically require frequent disassembly and assembly for maintenance and repair. Traditional fasteners require additional tools and are cumbersome to install; therefore, a tool-free connection clip is needed.

[0003] Tool-free installation connectors for hump pipes are structural components used for the quick assembly and fixing of hump pipes. In existing technologies, hump pipes are usually fixed by clamps or flanges, which requires the use of screwdrivers, wrenches or other tools, involves many steps and is time-consuming, affecting the use of hump pipes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tool-free connection clip for hump pipe installation, which aims to improve the problem that hump pipes are usually fixed by clamps or flanges, requiring additional tools for disassembly and assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tool-free connection buckle for hump pipe installation includes a pipe body with a sealing ring inside. The outer wall of the pipe body has two arc-shaped blocks: a first arc-shaped block and a second arc-shaped block. A toothed plate is fixedly connected to the outer wall of the first arc-shaped block, and the outer wall of the toothed plate is slidably connected to the interior of the second arc-shaped block. A worm gear is rotatably connected to the interior of the second arc-shaped block, and a fixing rod is fixedly connected to the outer wall of the worm gear. A worm wheel is meshed with the toothed end of the worm gear, and a connecting shaft is fixedly connected to the interior of the worm wheel. Both ends of the connecting shaft are rotatably connected to the interior of the second arc-shaped block. A gear is fixedly connected to the outer wall of the connecting shaft, and the toothed end of the gear meshes with the toothed end of the toothed plate. A positioning component is provided on the outer wall of the pipe body.

[0007] The above technical solution involves installing sealing rings, arc-shaped blocks, and toothed plates and their connecting structures on both the upper and lower sides of the pipe body. This facilitates the installation of the hump pipe in the upper and lower directions inside the pipe body. The diameter of the installed hump pipe must be smaller than the diameter of the pipe body to ensure a proper fit between the outer wall of the hump pipe and the inner wall of the pipe body. Simultaneously, the pipe body can be installed at the pipelines of other equipment. The sealing rings, combined with the pressure exerted by arc-shaped blocks one and two towards the center of the pipe body, maintain the airtight connection between the pipe body and other equipment pipelines. This operation eliminates the need for tools, thus achieving tool-free operation of the pipe body.

[0008] Preferably, the positioning component includes a positioning rod, the outer wall of which is fixedly connected to the outer wall of the tube body. The positioning rods are located on both sides of the tube body, and the outer walls of the positioning rods on both sides are disposed inside the arc-shaped block one and the arc-shaped block two.

[0009] Preferably, a hollow block is fixedly connected to the outer wall of the tube, and an L-shaped block is slidably connected inside the hollow block.

[0010] Preferably, a connecting block is fixedly connected to the upper surface of the L-shaped block, and the connecting block is connected to the hump pipe to be installed.

[0011] Preferably, a T-shaped rod is slidably connected inside the hollow block, and a U-shaped block is fixedly connected to the outer wall of the T-shaped rod.

[0012] Preferably, the outer wall of the U-shaped block is slidably connected to the interior of the hollow block, and the interior of the U-shaped block is disposed on the outer wall of the L-shaped block.

[0013] Preferably, a spring is fixedly connected to the outer wall of the U-shaped block, and the outer wall of the spring is fixedly connected to the inside of the hollow block.

[0014] Preferably, a short block is fixedly connected inside the U-shaped block, and the outer wall of the short block is disposed inside the L-shaped block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the cooperation between arc-shaped block one, toothed plate, arc-shaped block two, worm, fixed rod, worm wheel, connecting shaft and gear, the pipe body can be installed and disassembled without tools, simply by rotating the fixed rod, which improves the ease of operation of the pipe body. At the same time, the tool-free operation reduces the dependence on professional skills and tools, allowing ordinary personnel to complete the replacement and maintenance of the pipe body.

[0017] 2. In this utility model, the L-shaped block and the connecting block are limited or released by the cooperation between the hollow block, the T-shaped rod, the U-shaped block and the spring. Since the L-shaped block and the connecting block are fixed on the hump pipe to be installed, the position of the pipe body is locked after installation, so as to avoid the hump pipe from axial or radial displacement due to external force, and at the same time, the connection stability is enhanced.

[0026] 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.

[0027] Example 1:

[0028] Reference Figure 1, Figure 2 and Figure 3 This utility model provides an embodiment of a tool-free connection buckle for hump pipe installation, comprising a pipe body 1, a sealing ring 2 inside the pipe body 1, an arc-shaped block 3 and an arc-shaped block 5 on the outer wall of the pipe body 1, a toothed plate 4 fixedly connected to the outer wall of the arc-shaped block 3, the outer wall of the toothed plate 4 slidably connected to the inside of the arc-shaped block 5, a worm gear 6 rotatably connected to the inside of the arc-shaped block 5, a fixing rod 7 fixedly connected to the outer wall of the worm gear 6, a worm wheel 8 meshing with the tooth end of the worm gear 6, a connecting shaft 9 fixedly connected to the inside of the worm wheel 8, both ends of the connecting shaft 9 rotatably connected to the inside of the arc-shaped block 5, a gear 10 fixedly connected to the outer wall of the connecting shaft 9, the tooth end of the gear 10 meshing with the tooth end of the toothed plate 4, and a positioning component on the outer wall of the pipe body 1.

[0029] Specifically, the inner edges of both the upper and lower sides of the pipe body 1 are curved, which facilitates the sliding of pipes with diameters matching the inner diameter of the pipe body 1 into the interior of the pipe body 1. The sealing ring 2 reduces the gap between the equipment pipe and the pipe body 1. The sealing ring 2 is aligned with the arc-shaped block 3 and arc-shaped block 5 on the same transverse axis, which helps maintain the seal between the pipe body 1 and the equipment pipe when the arc-shaped block 3 and arc-shaped block 5 compress the pipe body 1. The rotation of the worm gear 6 is supported by the interior of the arc-shaped block 5, and the fixed rod 7 facilitates the operation of the worm gear 6. The rotation of the connecting shaft 9 is supported and limited by the interior of the arc-shaped block 5, thereby supporting and limiting the rotation of the worm wheel 8 and the connecting shaft 9. The characteristics between the worm gear 6 and the worm wheel 8 facilitate the self-locking of the pipe body 1 during installation.

[0030] Reference Figure 2 The positioning component includes a positioning rod 11. The outer wall of the positioning rod 11 is fixedly connected to the outer wall of the tube body 1. The positioning rod 11 is located on both sides of the tube body 1. The outer walls of the positioning rods 11 on both sides are set inside the arc-shaped block 3 and the arc-shaped block 5.

[0031] Specifically, positioning rods 11 are distributed on both sides of the tube body 1 to facilitate the positioning of the arc-shaped block 3 and the arc-shaped block 5, while preventing accidental rotation of the arc-shaped block 3 and the arc-shaped block 5. By setting multiple arc-shaped blocks 3, it is easy to adjust the different positions of the arc-shaped block 3 and the arc-shaped block 5 on the outer wall of the tube body 1.

[0032] Reference Figure 4 and Figure 5A hollow block 12 is fixedly connected to the outer wall of the tube body 1, and an L-shaped block 13 is slidably connected inside the hollow block 12; a connecting block 14 is fixedly connected to the upper surface of the L-shaped block 13, and the connecting block 14 is connected to the hump tube to be installed; a T-shaped rod 15 is slidably connected inside the hollow block 12, and a U-shaped block 16 is fixedly connected to the outer wall of the T-shaped rod 15; the outer wall of the U-shaped block 16 is slidably connected to the inside of the hollow block 12, and the inside of the U-shaped block 16 is set on the outer wall of the L-shaped block 13; a spring 17 is fixedly connected to the outer wall of the U-shaped block 16, and the outer wall of the spring 17 is fixedly connected to the inside of the hollow block 12;

[0033] Specifically, hollow blocks 12 are provided on both the upper and lower sides of the pipe body 1 to facilitate locking the installation of the upper and lower sides of the pipe body 1. The pipe body 1 is fixed to the hump pipe to be installed or to the equipment pipeline by the connecting block 14 and the L-shaped block 13. The movement of the L-shaped block 13 is limited by the inside of the hollow block 12. The movement of the U-shaped block 16 and the T-shaped rod 15 is offset by the inside of the hollow block 12. The elastic force of the spring 17 provides support for the U-shaped block 16 to limit the L-shaped block 13. The U-shaped block 16 is provided with an inclined surface on the side near the L end of the L-shaped block 13, so that the L-shaped block 13 can slide into the inside of the hollow block 12 and push the U-shaped block 16 to move. After moving to the appropriate position, the elastic force of the spring 17 makes the U-shaped block 16 limit the L-shaped block 13.

[0034] Example 2:

[0035] Reference Figure 6 A short block 18 is fixedly connected inside the U-shaped block 16, and the outer wall of the short block 18 is set inside the L-shaped block 13;

[0036] Specifically, since the U-shaped block 16 here does not have a bevel, the L-shaped block 13 cannot push the U-shaped block 16. However, a short block 18 is fixed inside the U-shaped block 16. Through the transmission of the short block 18 by the U-shaped block 16, the short block 18 slides in and out inside the L-shaped block 13, thereby limiting or releasing the L-shaped block 13.

[0037] Working principle: When using this buckle, the inner edge of the tube body 1 is set as a curved surface, which makes it easy to slide the tube body 1 into the equipment pipeline, or to slide other hump tubes into the inside of the tube body 1. When other pipelines are inside the tube body 1, the arc block 3 and the arc block 5 move towards the center of the tube body 1. The positioning rod 11 positions the arc block 3 and the arc block 5. After the toothed plate 4 slides into the inside of the arc block 5, it meshes with the gear 10. At the same time, the hand-held fixing rod 7 rotates the worm gear 6, which drives the worm wheel 8 to rotate. Through the connecting shaft 9, the gear 10 rotates, thereby pushing the toothed plate 4 to slide into the inside of the arc block 5, so that the arc block 3 and the arc block 5 are squeezed towards the center of the tube body 1, thus making it easier to install the tube body 1 on the equipment pipeline.

[0038] When installing the pipe body 1, it is fixed to the pipeline by the L-shaped block 13 and the connecting block 14. When the pipe body 1 moves towards the pipeline, the L-shaped block 13 slides into the interior of the hollow block 12. At the same time, the T-shaped rod 15 is pulled to the right, which drives the U-shaped block 16 to move to the right as well, compressing the spring 17. Through the movement of the U-shaped block 16, the L-shaped block 13 smoothly passes through the interior of the hollow block 12. When the L-shaped block 13 moves to the appropriate position, the T-shaped rod 15 is released. Under the elastic force of the spring 17, the outer wall of the U-shaped block 16 limits the L-shaped block 13. In addition, the short block 18 set in the U-shaped block 16 can slide into the interior of the L-shaped block 13 under the elastic force of the spring 17 for limiting, thereby achieving the locking of the pipe body 1 after installation. During use, the buckle can not only install and disassemble the pipe body 1 without tools, but also lock the position of the pipe body 1 after installation, preventing the pipe body 1 from moving accidentally.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
