Description

Technical Field

[0001] This invention relates to the field of automotive parts positioning and installation technology, specifically an environmentally friendly positioning lock to prevent automotive water pump hoses from falling off. Background Technology

[0002] The car water pump is a core component of the automotive cooling system. Its outlet pipe serves as a crucial channel for coolant delivery, and its installation accuracy directly affects the sealing performance and operating efficiency of the cooling system. Car water pump outlet pipes are mostly made of rubber or plastic, possessing a certain degree of elastic deformation. On the vehicle assembly line, traditional positioning methods often employ simple clips, cable ties, or manual hand-held positioning, which have numerous technical drawbacks.

[0003] In the prior art, for example, patent CN219519451U discloses a pipe positioning device. Although it can achieve basic clamping and positioning, it has poor adaptability to automotive water pump outlet pipes. Its clamping structure is a rigid design, which is prone to squeezing damage to flexible outlet pipes. Moreover, the angle adjustment flexibility after positioning is insufficient, and it cannot adapt to the complex installation space requirements in the engine compartment. At the same time, the connection structure of traditional positioning devices has low strength, and it is easy to loosen or shift during assembly operations, resulting in a decrease in the docking accuracy between the outlet pipe and the water pump interface, which can easily lead to coolant leakage problems. The disassembly and assembly steps of some positioning devices are cumbersome and require the use of special tools, which increases the labor cost of assembly and maintenance and reduces production efficiency.

[0004] Furthermore, existing automotive water pump outlet pipe positioning devices generally lack anti-detachment and anti-slip structures. During vehicle operation, engine vibrations are transmitted to the outlet pipe, easily causing relative slippage between the positioning device and the outlet pipe. Long-term vibration can also lead to fatigue damage at the connection points of the positioning structure, further reducing positioning stability. Additionally, traditional devices have poor component interchangeability; different positioning parts are required for water pump outlet pipes of different diameters and bending angles, increasing production and warehousing costs. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly positioning lock for preventing the water pump hose from falling off a car, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly anti-detachment positioning lock for car water pump pipes, comprising an arc-shaped outer shell, a locking ring buckle one, a locking ring buckle two, a rotating column, and an extension rod. The locking ring buckle one and the locking ring buckle two are respectively installed on both sides of the arc-shaped outer shell. The rotating column is rotatably installed inside the locking ring buckle one. One end of the extension rod passes through the interior of the locking ring buckle two, and one end of the extension rod is fixed to the surface of the rotating column. The inner cavity of the arc-shaped outer shell is configured as a pipe positioning, tightening, and locking assembly.

[0007] The pipe positioning, tightening, and locking assembly includes a locking shell, which is configured as several groups. The several groups of locking shells are arranged in a ring array inside the arc-shaped outer shell. Arc-shaped lifting shells I are extended on both sides of the locking shell, and arc-shaped lifting shells II are extended on both sides of the arc-shaped lifting shells I.

[0008] The locking shell surface is provided with an arc-shaped cavity, and the arc-shaped cavity, the first arc-shaped lifting shell, and the second arc-shaped lifting shell form an anti-slip band. The surfaces of the first arc-shaped lifting shell and the second arc-shaped lifting shell are provided with anti-slip pads.

[0009] The extension rod has an external thread on its surface, and an anti-disengagement ring is provided at one end of the extension rod; a locking nut is threaded onto the external thread surface, and a magnetic ring is installed on one side of the locking nut, and the magnetic ring is magnetically fixed to one side of the locking ring.

[0010] A reinforcing ring is provided in the area where the locking ring one connects with the arc-shaped outer shell, and an opening groove is also provided on the locking ring one. A reinforcing ring is provided in the area where the locking ring two connects with the arc-shaped outer shell.

[0011] The anti-slip pad is made of elastic rubber, and the surface of the anti-slip pad away from the arc-shaped lifting shell one and arc-shaped lifting shell two is provided with anti-slip texture; the anti-disengagement ring and the extension connecting rod are an integral structure, and the outer diameter of the anti-disengagement ring is larger than the inner diameter of the locking nut, thus forming an axial limit on the locking nut.

[0012] The locking ring buckle one has a rotating cavity inside that is adapted to the rotating column. The rotating column is embedded in the rotating cavity and rotates in cooperation with the locking ring buckle one. The locking ring buckle two has a through hole at the position corresponding to the extension connecting rod. The extension connecting rod is fitted with the through hole with a clearance to ensure the smoothness of the extension connecting rod when rotating with the rotating column.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. During use, the arc-shaped outer shell cooperates with the pipe positioning and locking components in the inner cavity to achieve full-wrap positioning of the car water pump outlet pipe. The anti-slip band composed of the arc-shaped concave cavity, arc-shaped lifting shell one, and arc-shaped lifting shell two, in conjunction with the anti-slip rubber pad, greatly increases the friction with the outer wall of the outlet pipe, effectively preventing axial and circumferential sliding between the positioning device and the outlet pipe. This solves the positioning offset problem in the existing technology, and the positioning accuracy can reach ±0.5mm, ensuring the precise connection between the outlet pipe and the water pump interface and avoiding coolant leakage. 2. When in use, the anti-slip pads are made of elastic rubber, which has good cushioning performance. During the positioning and fixing process, they will not cause squeezing damage to the flexible water pump outlet pipe. At the same time, they can buffer the impact force brought by engine vibration, reduce fatigue damage to the outlet pipe, and extend the service life of the outlet pipe. The ends of the arc-shaped shell one and arc-shaped shell two are rounded to further prevent scratching the pipe fittings and improve the protection effect on the water pump outlet pipe. 3. During use, the rotating engagement structure of the rotating column and the extension connecting rod, the rotating engagement of the rotating column with the rotating cavity of the locking ring buckle one, and the clearance engagement of the extension connecting rod with the through hole of the locking ring buckle two, allow the arc-shaped outer shell to rotate 360° around the rotating column. This allows for flexible adjustment of the positioning angle of the water outlet pipe according to the complex installation space in the engine compartment, adapting to different assembly conditions. This solves the problem of insufficient flexibility in positioning angle adjustment in the existing technology and improves the adaptability of the device. 4. When in use, the positioning device can be tightened and loosened by rotating the locking nut. The magnetic attraction between the magnetic ring and the second locking ring further improves the ease of assembly and disassembly, while ensuring the stability after locking. The opening groove on the first locking ring gives it a certain elastic deformation capability, which facilitates the installation and disassembly of the rotating column, greatly reducing the time and cost of assembly and maintenance, and improving production efficiency. 5. During use, the connection areas of locking ring one and locking ring two with the arc-shaped outer shell are respectively equipped with reinforcing ring one and reinforcing ring, which effectively improves the structural strength of the connection parts and prevents the area from breaking due to stress concentration; the rotating column is made of high-hardness bearing steel and is chrome-plated; the extension connecting rod and the anti-loosening retaining ring are integral forged structures; the locking nut adopts a hexagonal flange anti-loosening design; the overall structure has high strength and good vibration resistance, and can adapt to the vibration conditions in the engine compartment. It solves the problems of easy loosening and fatigue damage of the positioning device in the existing technology and improves the service life of the device; 6. When in use, the curvature of the inner cavity of the arc-shaped outer shell can be adapted to the water outlet pipe of the car water pump with different pipe diameters. The length of the extension rod can be flexibly adjusted. The magnetic strength of the magnetic ring is moderate. The elasticity of the anti-slip rubber pad is adapted to pipes with different wall thicknesses. The device is highly versatile. For water pump outlet pipes of different specifications, there is no need to replace a large number of parts. Only the inner cavity specifications of the arc-shaped outer shell need to be adjusted, which reduces production and storage costs. 7. During use, all parts are made of rust-proof, corrosion-resistant and oil-resistant materials. For example, locking ring one and locking ring two are made of stainless steel, the locking nut is hot-dip galvanized, the anti-slip pad is made of nitrile rubber, and the magnetic ring is wrapped with a plastic protective layer. It is suitable for the harsh working environment of high temperature, high humidity and lots of oil in the engine compartment, which improves the environmental adaptability of the device.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Please refer to [link to relevant documentation]. Figure 1-5 The present invention provides a technical solution: An environmentally friendly anti-detachment positioning lock for car water pump pipes includes an arc-shaped outer shell 1, a locking ring buckle 2, a locking ring buckle 3, a rotating column 4, and an extension rod 5. Locking ring buckle 2 and locking ring buckle 3 are respectively installed on both sides of the arc-shaped outer shell 1. The rotating column 4 is rotatably installed inside locking ring buckle 2. One end of the extension rod 5 passes through the interior of locking ring buckle 3, and the other end is fixed to the surface of the rotating column 4. The inner cavity of the arc-shaped outer shell 1 is configured as a pipe positioning and tightening locking assembly. The pipe positioning and tightening locking assembly includes a locking shell 6, which is configured as several groups arranged in a ring array within the inner cavity of the arc-shaped outer shell 1. Arc-shaped prying shells 61 extend from both sides of the locking shell 6, and arc-shaped prying shells 63 extend from both sides of the arc-shaped prying shells 61. The locking shell 6 has an arc-shaped cavity 64 on its surface. The arc-shaped cavity 64, arc-shaped prying shell 1 61, and arc-shaped prying shell 2 63 form an anti-slip band. The surfaces of arc-shaped prying shell 1 61 and arc-shaped prying shell 2 63 are provided with anti-slip pads 62. The extension rod 5 has an external thread 51 on its surface. One end of the extension rod 5 is provided with an anti-disengagement ring 54. A locking nut 53 is threaded onto the surface of the external thread 51. A magnetic ring 52 is installed on one side of the locking nut 53. The magnetic ring 52 is magnetically fixed to one side of the locking ring buckle 2 3. A reinforcing ring block 21 is provided in the connection area between the locking ring buckle 1 2 and the arc-shaped shell 1. A reinforcing ring 31 is provided in the connection area between the locking ring buckle 2 3 and the arc-shaped shell 1. The anti-slip pad 62 is made of elastic rubber, and the surface of the anti-slip pad 62 away from the arc-shaped prying shell 1 61 and arc-shaped prying shell 2 63 is provided with anti-slip texture. The anti-disengagement ring 54 and the extension connecting rod 5 are an integral structure, and the outer diameter of the anti-disengagement ring 54 is larger than the inner diameter of the locking nut 53, thus providing axial restraint for the locking nut 53. The locking ring buckle 2 has a rotating cavity inside that is adapted to the rotating column 4, and the rotating column 4 is embedded in the rotating cavity and rotates in cooperation with the locking ring buckle 2.

[0020] Furthermore, the arc-shaped outer shell 1 is integrally injection molded from engineering plastic material. Its inner cavity curvature matches the outer wall curvature of the car water pump outlet pipe. The wall thickness of the arc-shaped outer shell 1 is 3-5mm, ensuring structural strength while also possessing a certain degree of lightweight characteristics. The two ends of the arc-shaped outer shell 1 are connected to the locking ring buckle 1 2 and locking ring buckle 2 3 by hot-melt welding or bolt fixing. Sealing rings are provided on the connection surfaces to improve connection sealing and structural stability. Furthermore, both locking ring buckle 1 2 and locking ring buckle 2 3 are semi-circular ring structures made of stainless steel, possessing rust-proof and corrosion-resistant properties, suitable for the harsh working environment inside the engine compartment. The opening groove 22 on locking ring buckle 1 2 is radially opened, with a groove width of 2-4mm. The opening groove 22 provides locking ring buckle 1 2 with a certain degree of elastic deformation capability, facilitating the installation and removal of the rotating column 4, while also buffering the stress caused by engine vibration. Furthermore, the reinforcing ring 21 and the locking ring buckle 2 are integrally forged structures. The thickness of the reinforcing ring 21 is 1.5-2 times the thickness of the locking ring buckle 2 body, and its outer diameter is 5-8mm larger than that of the locking ring buckle 2 body. This effectively improves the structural strength of the connection between the locking ring buckle 2 and the arc-shaped outer shell 1, preventing breakage due to stress concentration in this area. The structure of the reinforcing ring 31 is consistent with that of the reinforcing ring 21, and it is symmetrically arranged in the connection area between the locking ring buckle 3 and the arc-shaped outer shell 1 to achieve a balance of connection strength on both sides. Furthermore, the rotating column 4 is made of high-hardness bearing steel with a chrome-plated surface and a roughness Ra≤0.8μm, reducing the coefficient of friction during rotation. Both ends of the rotating column 4 are provided with annular limiting flanges, the outer diameter of which is larger than the inner diameter of the rotating cavity, to prevent axial displacement of the rotating column 4 during rotation and ensure rotational stability. Furthermore, the extension link 5 is a cylindrical metal rod with a length of 100-200mm, which can be flexibly adjusted according to the installation space in the engine compartment. The extension link 5 is fixed to the rotating column 4 by welding or key connection to ensure the reliability of torque transmission. The external thread 51 has a pitch of 1.5-2mm and adopts a fine thread design to improve the locking accuracy and anti-loosening performance of the locking nut 53. Furthermore, the magnetic ring 52 is a ring structure made of permanent magnet ferrite material. Its inner diameter is adapted to the outer diameter of the extension link 5. The magnetic strength of the magnetic ring 52 is 800-1200 Gauss, which can achieve reliable magnetic fixation with the locking ring buckle 3 without causing difficulty in disassembly and assembly due to excessive magnetic force. The surface of the magnetic ring 52 is covered with a plastic protective layer to prevent the magnetic ring 52 from rusting and scratching the surface of the locking ring buckle 3.Furthermore, the locking nut 53 is a hexagonal flange nut with anti-slip teeth on the flange surface. A rubber gasket is provided on the side that contacts the magnetic ring 52 to improve the anti-loosening performance after locking. The locking nut 53 is made of carbon steel and hot-dip galvanized, providing good rust resistance. Furthermore, the anti-slip ring 54 is 8-12mm thick, with chamfered edges to prevent scratching operators and surrounding parts. The anti-slip ring 54 and the extension rod 5 are integrally formed using forging technology, with no connecting gaps, improving the overall structural strength and effectively preventing the locking nut 53 from slipping off the extension rod 5. Furthermore, the locking shell 6 and the arc-shaped outer shell 1 are integrally injection molded. The annular array of several sets of locking shells 6 is spaced 5-8mm apart to ensure uniform wrapping and positioning of the water pump outlet pipe. The arc of the arc-shaped cavity 64 of the locking shell 6 is perfectly matched with the arc of the outer wall of the water pump outlet pipe, so that the anti-slip strip fits tightly with the outer wall of the outlet pipe, improving the anti-slip effect. Furthermore, both the arc-shaped prying shell 1 61 and the arc-shaped prying shell 2 63 are raised towards the inner cavity of the arc-shaped outer shell 1 at an angle of 15-30°, forming a concave-convex anti-slip structure with the arc-shaped cavity 64, effectively preventing axial sliding between the outlet pipe and the positioning device. The ends of the arc-shaped prying shell 1 61 and the arc-shaped prying shell 2 63 are rounded to prevent scratching the outer wall of the water pump outlet pipe. Furthermore, the anti-slip pad 62 is made of nitrile rubber, which has good elasticity, wear resistance and oil resistance, making it suitable for the oil environment in the engine compartment. The anti-slip pad 62 is 2-4mm thick, and the anti-slip texture on the surface is a diamond mesh structure with a depth of 0.5-1mm, which further enhances the friction with the outer wall of the water pump outlet pipe and prevents relative slippage.

It is fixed to the surface of the arc-shaped tilt shell 1 61 and the arc-shaped tilt shell 2 63 by adhesive bonding.

[0022] Example 2 This embodiment provides an environmentally friendly anti-detachment positioning lock for automotive water pump hoses, compatible with 40mm diameter plastic water outlet hoses of automotive water pumps. Based on Embodiment 1, the following structural adjustments are made: Arc-shaped outer shell 1: The inner cavity curvature matches the outer wall of the 40mm diameter water outlet hose, with a length of 180mm; Locking shell 6: A total of 8 sets, arranged in a ring array with a spacing of 7mm, the arc-shaped concave cavity 64 with a curvature matching the 40mm diameter water outlet hose; Arc-shaped prying shell 1 61 and Arc-shaped prying shell 2 63: Prying angle 25°, adapting to the hardness characteristics of the plastic water outlet hose, improving the anti-slip effect; Anti-slip pad 62: 4mm thick, with a 1mm deep anti-slip texture on the surface, increasing friction with the outer wall of the plastic water outlet hose; Extension rod 5: 180mm long, adapting to the installation space of the 40mm diameter water outlet hose; Magnetic ring 52: Magnetic strength 1200 Gauss, enhancing the connection with the locking ring 2 3. Its magnetic attraction provides a secure hold, making it suitable for the positioning of plastic water pipes.

[0023] The structure, material, and connection method of the remaining components are the same as in Example 1.

[0024] Working principle The inner curvature of the arc-shaped outer shell 1 precisely matches the outer curvature of the water outlet pipe of the car water pump. Several sets of locking shells 6 are arranged in a ring array within the inner cavity, enabling the pipe positioning and tightening locking assembly to achieve a full-wrap fit to the water outlet pipe. The arc-shaped concave cavity 64 on the surface of the locking shell 6 completely fits the outer wall of the water outlet pipe, forming a basic positioning and fitting surface. Arc-shaped prying shell 1 61 and arc-shaped prying shell 2 63 pry upwards towards the inner cavity, forming a concave-convex fit structure with the arc-shaped concave cavity 64, limiting the circumferential and axial movement of the water outlet pipe and preventing relative rotation and axial sliding between the water outlet pipe and the positioning device. Meanwhile, the anti-slip pads 62 on the surfaces of the arc-shaped shell 61 and arc-shaped shell 63 are made of elastic rubber. During the bonding process, they undergo slight elastic deformation, filling the tiny gaps between the shell and the outer wall of the water outlet pipe, ensuring complete contact and significantly increasing contact friction. This further enhances the bonding and positioning effect, achieving precise positioning of the water outlet pipe and ensuring the coaxiality and docking accuracy of the water outlet pipe and the water pump interface. Through the rotational cooperation of the rotating column 4, the extension rod 5, and the locking ring buckles 2 and 3, the arc-shaped shell 1 can achieve 360° circumferential angle adjustment. The rotating column 4 is embedded in the rotating cavity of the locking ring buckle 2, rotating in cooperation with the locking ring buckle 2 and preventing axial displacement through the annular limiting flanges at both ends, ensuring the stability of the rotation. One end of the extension rod 5 is fixedly connected to the rotating column 4, and the other end passes through the through hole of the locking ring buckle 3 and is fitted with the through hole with a gap, so that the extension rod 5 can rotate synchronously with the rotating column 4 without jamming during the rotation. The arc-shaped outer shell 1 is fixedly connected to locking ring 1 2 and locking ring 2 3. When the arc-shaped outer shell 1 is rotated, locking ring 1 2 and locking ring 2 3 drive the rotating column 4 and the extension connecting rod 5 to rotate synchronously, realizing the 360° circumferential rotation of the arc-shaped outer shell 1 around the water outlet pipe. This allows for flexible adjustment of the positioning angle of the water outlet pipe, adapting to the complex installation space and different assembly conditions in the engine compartment, and solving the problem of insufficient flexibility in angle adjustment of traditional positioning devices. The dual fixing method combining threaded locking and magnetic fixing achieves reliable fixing of the rotation angle of the arc-shaped outer shell 1, while ensuring convenient disassembly and assembly. The fine-pitch external thread 51 on the surface of the extension link 5 engages with the locking nut 53. The fine-pitch thread design improves locking accuracy and anti-loosening performance. When the locking nut 53 is rotated, the axial movement of the locking nut 53 is achieved through thread transmission, pushing the magnetic ring 52 to engage with the locking ring buckle 3. The magnetic force generated by the magnetic ring 52 achieves magnetic attraction and fixation with the locking ring buckle 3, forming the first layer of fixation. At the same time, the flange face of the locking nut 53 abuts tightly with the magnetic ring 52. The anti-slip teeth and rubber gasket on the flange face increase the contact friction, preventing the locking nut 53 from loosening due to engine vibration, forming the second layer of threaded locking fixation.The dual fixing method ensures both reliable fixation and convenient assembly / disassembly. The fixing can be released simply by rotating the locking nut 53 in the reverse direction, requiring no special tools and significantly improving assembly and maintenance efficiency. The anti-slip pad 62, made of elastic rubber, has excellent elastic cushioning performance. During positioning and fixing, the anti-slip pad 62 makes flexible contact with the outer wall of the water outlet pipe, preventing squeezing damage to the flexible rubber or silicone water outlet pipe. It also buffers the impact force from engine vibration, reducing fatigue damage to the water outlet pipe and extending its service life. The ends of the arc-shaped prying shell 1 61 and arc-shaped prying shell 2 63 are rounded to prevent scratching the outer wall of the water outlet pipe. The rubber gasket between the locking nut 53 and the magnetic ring 52 buffers the squeezing force during locking, preventing scratches on the surfaces of the magnetic ring 52 and the locking ring buckle 2 3. The arc-shaped outer shell 1 is made of engineering plastic, which is lightweight and has a certain degree of elasticity, further enhancing the protection of the water outlet pipe.
