Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology. Specifically, this invention relates to a double-groove pipe fixing device for mini trucks. Background Technology

[0002] Existing dual-groove pipe fixing devices mostly adopt an integrated fixing structure: the relative position and angle of the two pipe fixing grooves are preset values ​​and cannot be adjusted after production; during installation, the pipes must be completely aligned with the pipe fixing grooves and then fixed to the vehicle body with fasteners.

[0003] Current technology can only accommodate parallel and fixed-position pipes. If the vehicle's pipes are not parallel or have misaligned layouts, the pipe fixing groove cannot fit snugly against the pipe, resulting in insufficient clamping force and easy loosening. Furthermore, its versatility is limited. For different vehicle models with varying pipe routing or different pipe diameters on both sides, existing designs are difficult to adjust to accommodate these situations. This necessitates separate design and mold making for specific pipe locations, increasing time and labor costs. Disassembly and installation are also inconvenient. If only one side of the pipe fixing groove needs to be replaced, the entire device must be disassembled and replaced, significantly increasing workload and reducing assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dual-groove pipe fixing device for mini-trucks that is easy to install and operate, highly versatile, and facilitates pipe disassembly and replacement.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The mini-truck dual-groove pipe fixing device includes a support base and a pipe fixing groove, wherein the pipe fixing groove is rotatably mounted on the support base.

[0006] The pipe fixing groove is provided with a screw hole in the middle, and the support base is provided with a connection hole corresponding to the screw hole. The pipe fixing groove and the support base are connected by fastening screws.

[0007] The pipe fixing groove includes a U-shaped groove, with locking teeth above the U-shaped groove and clearance space below the locking teeth on the pipe fixing groove; the locking teeth are located at both ends of the top of the pipe fixing groove and are arranged opposite to each other, with one end of the locking teeth being inclined.

[0008] The support base has a connecting column in the middle, and the connecting column has a vehicle body mounting hole in the middle. The connecting column and the support base are an integral structure. There are two pipe fixing grooves, which are located on both sides of the connecting column.

[0009] The top surface of the support base is provided with an upper support surface, and the bottom of the pipe fixing groove is in contact with the upper support surface; the top of the connecting column is provided with an extension plate, the bottom of the extension plate is provided with a lower support surface, and the lower support surface is in contact with one end of the top of the pipe fixing groove.

[0010] The axis of the vehicle body mounting hole is parallel to the axis of the screw hole.

[0011] The screw hole is a trapezoidal hole, the head of the fastening screw is located at the top of the screw hole, and the top of the fastening screw is lower than the bottom of the U-shaped groove.

[0012] The installation method of this mini-truck dual-groove pipe fixing device includes the following steps: S1. Install the support base; S2. Preliminary positioning of the pipe fixing groove; S3. Adjust the angle of the pipe fixing groove and install the pipe; S4. Lock the pipe fixing groove.

[0013] Step S1 includes the following steps: S1-1, fitting the lower support surface with the preset mounting plane of the vehicle body; S1-2, aligning the mounting holes of the vehicle body with the preset threaded holes of the vehicle body until the axis coincides.

[0014] Step S2 includes the following steps: S2-1, The pipe fixing groove is placed on the lower support surface; S2-2. Align the screw holes with the connecting holes; S2-3. Screw the fastening screws into the screw hole and the connecting hole in sequence, and tighten them until the head of the fastening screw is coplanar with the bottom of the U-shaped groove, leaving 1-2 turns of thread for locking.

[0015] The technical advantages of this invention are as follows: The micro-truck double-groove pipe fixing device of this invention allows for angle adjustment of the pipe fixing grooves without the need for additional tooling, making operation convenient; its independent adjustment design adapts to different pipe layouts, offering strong versatility; the combination of the clamping teeth and the anti-loosening structure effectively improves the stability and durability of pipe fixing; it solves the problems of existing double-groove pipe fixing devices being unable to adapt to non-parallel or interfering pipes, failing to meet the fixing requirements of different vehicle models and pipe diameters, and having low disassembly and assembly efficiency.

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] like Figure 1 As shown, this dual-groove pipe fixing device for mini-trucks includes a support base 1 and a pipe fixing groove 2, which is rotatably mounted on the support base 1. By making the pipe fixing groove 2 a rotatable structure, the traditional one-piece fixing groove with a fixed angle is changed, allowing the same structure to adapt to pipe layouts with different orientations. When the pipe has a certain angle, there is no need to replace the fixing device; simply rotating the pipe fixing groove 2 achieves angle matching, resulting in high versatility and adaptability. The rotatable connection of the pipe fixing groove 2 allows fixing devices produced with the same mold to be applied to various vehicle models or pipe layout scenarios, reducing the types of materials required for different vehicle models and simplifying material and inventory management on the assembly line. Furthermore, for the vehicle aftermarket repair market, repair personnel can use one device or fixing groove to handle most repair scenarios, improving the convenience of after-sales service.

[0020] like Figure 1As shown, the pipe fixing groove 2 has a screw hole 203 in the middle, and the support base 1 has a connecting hole 103 corresponding to the screw hole 203. A fastening screw 3 connects the pipe fixing groove 2 and the support base 1. After the connecting hole 103 is positioned with the screw hole 203 on the pipe fixing groove 2, the pipe fixing device assembly can be installed on the vehicle body via the vehicle body connecting bolts 7 by connecting the two through holes through the fastening screw 3. The head of the fastening screw 3 is accommodated in the screw hole 203, ensuring that the tightened fixing screw will not contact the pipe and cause damage. The fastening screw 3 is a joint for adjusting the rotation angle of the pipe fixing device and also serves as its locking element. When it is necessary to adjust the pipe fixing groove 2 to a certain angle, the fastening screw 3 is first loosened to allow the pipe fixing groove 2 to rotate. After rotating to the desired position, the fastening screw 3 is then tightened. The fastening screw 3 provides both rotation and locking functions, simplifying the structural design and reducing the number of parts. The screw hole 203 is located in the middle of the pipe fixing groove 2, ensuring that the forces on both sides of the pipe fixing groove 2 remain balanced when rotating around the fastening screw 3, avoiding rotational jamming or obstruction caused by eccentric torque. The head of the installed fastening screw 3 is completely accommodated within the screw hole 203, with its top surface lower than the bottom of the U-shaped groove 201. This concealed design not only avoids direct contact between the screw head and the pipe but also makes the entire device look cleaner and reduces the risk of snagging other wiring harnesses or components. During long-term vehicle operation, it also effectively prevents the screw head threads from being corroded by mud, sand, and moisture, extending the service life of the fastener.

[0021] like Figure 2 As shown, the pipe fixing groove 2 includes a U-shaped groove 201, with clamping teeth 202 above the U-shaped groove 201 and clearance space below the clamping teeth 202. The clamping teeth 202 are located at both ends of the top of the pipe fixing groove 2 and are positioned opposite each other, with one end of the clamping teeth 202 inclined. The clearance space below the clamping teeth 202 allows the clamping teeth 202 to undergo elastic deformation when the pipe is pressed into them, reducing pressing resistance and making pipe installation easier. The inclined design of the clamping teeth 202 causes them to undergo elastic deformation when the pipe is pressed in, using the material's own elastic restoring force to clamp the pipe, forming a reliable clamping fit. The arc-shaped surface of the U-shaped groove 201 fits against the outer circumference of the pipe, increasing the contact area and making the clamping force distribution more uniform, avoiding local stress concentration that could damage the pipe. The clamping teeth 202 and the U-shaped groove 201 form a double clamping structure, restraining the pipe from two directions and effectively preventing the pipe from loosening in a vibrating environment. After installation, the ends of the clamping teeth 202 and the U-shaped groove 201 are both in contact with the outer circumference of the pipe. Specifically, the U-shaped groove 201 is in contact with the outer circumference of the bottom of the pipe and the outer circumference of the top of the pipe. The two are in contact to form a surrounding clamping of the pipe, which effectively restricts the pipe from coming out and makes the pipe as a whole stable and fixed.

[0022] like Figure 1 As shown, a connecting column 101 is provided in the middle of the support base 1, and a vehicle body mounting hole 104 is provided in the middle of the connecting column 101. The connecting column 101 and the support base 1 are an integral structure. There are two pipe fixing grooves 2, which are located on both sides of the connecting column 101. The vehicle body mounting hole 104 is used to fix the support base 1 to the vehicle body. Its fixing point is located in the central area of ​​the device. The precise alignment of the vehicle body mounting holes 104 ensures the positional accuracy of the device after installation. After bolt connection, the device is evenly stressed, avoiding tilting or loosening caused by uneven load. Each pipe fixing groove 2 can be independently adjusted by ±30°, and the two mating grooves can be adjusted by a maximum of ±60°. The fixing groove body is a U-shaped groove structure. The clamping teeth 202 are arc-shaped protrusions that are adapted to the cylindrical shape of the pipe and prevent it from falling off. There are 4 clamping teeth 202 on each pipe fixing groove 2, which makes the clamping force more balanced. When using, after adjusting the angle of the pipe fixing groove 2, the pipe is placed in the clamping teeth 202 and then pressed into the pipe fixing groove 2. Compared to traditional integrated mounting slots, each pipe mounting slot 2 is independently adjustable, allowing for angle adjustments based on the actual pipe layout. This enables the fixing of both parallel and angled pipes. The ±30° adjustment range covers the pipe layout requirements of most vehicle models, and the two mounting slots can be adjusted together to achieve a maximum angle difference of 60°, meeting the installation requirements of various vehicle types, from cars to trucks.

[0023] like Figure 2As shown, the top surface of the support base 1 is provided with an upper support surface 105, and the bottom of the pipe fixing groove 2 is in contact with the upper support surface 105; the top of the connecting column 101 is provided with an extension plate 102, and the bottom of the extension plate 102 is provided with a lower support surface 106, which is in contact with one end of the top of the pipe fixing groove 2. The upper support surface 105 is a smooth plane, which provides support for the pipe fixing groove 2 on the one hand, reducing the loosening of the fastening screw 3 due to gravity or vehicle body vibration, and on the other hand, provides structural strength for the support base 1 as a whole; the bottom of the lower support surface 106 is in contact with the vehicle body, providing support. The contact design between the upper support surface 105 and the bottom of the pipe fixing groove 2 forms a surface contact support structure, which evenly transfers the load borne by the pipe fixing groove 2 to the support base 1, avoiding the load concentration on a single point of force on the fastening screw 3, and improving the load-bearing capacity and vibration resistance of the device. The close fit between the upper and lower support surfaces 106 and the pipe fixing groove 2 increases the transmission path of pipe vibration, enabling vibration energy to be effectively and quickly transferred to the vehicle body, reducing the resonance risk of the pipe system and ensuring the overall stability of the device installation. The upper support surface 105 has a high surface flatness and a small gap between it and the bottom of the pipe fixing groove 2. When the fastening screw 3 is tightened, the bottom of the pipe fixing groove 2 and the upper support surface 105 form a tight fit. The force between the two and the locking force of the fastening screw 3 work together to provide auxiliary constraint for the rotation of the pipe fixing groove 2 after installation, making the angle locking more reliable. The bottom surface of the support base 1 forms a large contact area with the vehicle body sheet metal, which can more effectively transfer the vibration energy borne by the device to the vehicle body structure, using the vehicle body sheet metal to absorb and disperse the vibration energy, reducing the vibration amplitude of the device itself and the pipe.

[0024] like Figure 1 and Figure 2 As shown, the axis of the body mounting hole 104 and the axis of the screw hole 203 are parallel. This design ensures that the assembly and force directions of the two bolted connectors are consistent. During installation, the parallel axes prevent interference with the operating space of the assembly tools, making it easier for the assembler to apply force and improving assembly efficiency. At the same time, it keeps the preload directions of the two connectors independent, preventing mutual interference and maintaining their respective locking effects, thus ensuring the reliability of the connection.

[0025] As shown in Figure 2, the screw hole 203 is a trapezoidal hole, and the head of the fastening screw 3 is located at the top of the screw hole 203, with the top of the fastening screw 3 lower than the bottom of the U-shaped groove 201. This structure provides multiple protective functions. First, it avoids direct contact between the screw head and the pipe, preventing the sharp edge of the screw from contacting or scratching the pipe surface. Second, this recessed design creates an annular cavity around the screw head. When the pipe is pressed into the U-shaped groove 201, the pipe covers the screw hole 203, physically shielding the screw head. This reduces the impact of mud, water vapor, and other contaminants on the connection point of the device during vehicle use. Furthermore, the low position of the screw head makes it difficult for these contaminants to accumulate at the bottom of the U-shaped groove 201, thus preventing them from directly intruding into the mating gap between the screw head and the screw hole 203, reducing the risk of corrosion and jamming. In addition, the screw being entirely located inside the device makes the overall structure more compact, suitable for placement in space-constrained vehicle chassis areas, avoiding interference with other chassis components.

[0026] like Figures 5 to 8 As shown, the installation method of the dual-groove pipe fixing device for the mini-truck includes the following steps: S1. Install support base 1; S2, Preliminary positioning of pipe fixing groove 2; S3. Adjust the angle of pipe fixing groove 2 and install the pipe; S4, Lock pipe fixing groove 2.

[0027] like Figure 2 As shown, step S1 includes the following steps: S1-1, aligning the lower support surface 106 with the preset mounting plane of the vehicle body; S1-2, aligning the vehicle body mounting hole 104 with the preset threaded hole of the vehicle body until their axes coincide. These steps ensure complete alignment of the lower support surface 106 with the vehicle body mounting plane, guaranteeing stable contact between the support seat 1 and the vehicle body. Precise alignment of the mounting hole axes prevents misalignment caused by improper bolt installation, thus preventing thread damage or loosening of the connection.

[0028] Step S2 includes the following steps: S2-1, placing the pipe fixing groove 2 on the lower support surface 106; S2-2, aligning the screw hole 203 with the connecting hole 103; S2-3, screwing the fastening screw 3 into the screw hole 203 and the connecting hole 103 in sequence, tightening until the head of the fastening screw 3 is coplanar with the bottom of the U-shaped groove 201, leaving a locking allowance of 1-2 turns of thread. In the above steps, by not fully tightening the fastening screw 3, the pipe fixing groove 2 can rotate freely around the screw without falling off the support 1, leaving room for subsequent angle adjustment. The fastening screw 3, in the pre-tightened state, has an adjustable effect, allowing installers to complete angle adjustments without disassembling parts, greatly improving installation efficiency. The 1-2 turns of thread allowance serves as a control standard for bolt installation, and practical verification has shown that it ensures adjustability while preventing the screw from falling off due to excessive looseness.

[0029] Reference Figures 1-2 As shown, this double-groove pipe fixing device consists of a support base 1, two identical pipe fixing grooves 2, and two sets of matching fastening screws 3, reducing the number of parts and lowering production costs. The two pipe fixing grooves 2 are symmetrically arranged on the lower support surface 106 of the support base 1, ensuring balanced force distribution across the entire device. They are connected to the support base 1 via the fastening screws 3 in a detachable manner, allowing each pipe fixing groove 2 to be independently adjusted in position and angle. The device provides references for two constraint installation states: parallel pipe 4 and non-parallel pipe 5. Figure 3 , Figure 4 The installation steps for pipe fixing devices and their connection to the vehicle body and piping system are described in the reference. Figures 5 to 8 .

[0030] The specific installation method for this double-groove pipe fixing device is as follows: 1. Fixed installation of support base 1: Refer to Figures 1-5 First, the lower support surface 106 of the support base 1 is fully aligned with the preset mounting plane of the vehicle body. During the alignment process, the positions of the vehicle body mounting threaded through hole at the bottom of the support base 1 and the preset threaded hole on the vehicle body must be precisely calibrated to ensure that their axes are completely coincident and without misalignment. Then, take the vehicle body connecting bolts 7 of the matching specifications and pass them through the preset threaded hole on the vehicle body and the vehicle body mounting threaded through hole of the support base 1 in sequence. Tighten them with a torque wrench at a standard torque value of 10-12 N•m. After tightening, check the installation status of the support base 1 to ensure that it is free from warping deformation and positional offset relative to the vehicle body. This provides a stable and reliable installation benchmark for the subsequent angle adjustment of the pipe fixing groove 2.

[0031] 2. Preliminary positioning of pipe fixing groove 2: (Refer to...) Figures 1-5Based on the actual layout requirements of the vehicle's piping system, after determining whether the pipes to be fixed are in a parallel or non-parallel layout, the two pipe fixing slots 2 are placed in the preset areas of the lower support surface 106 of the support base 1. Next, the screw holes 203 on the pipe fixing slots 2 are precisely aligned with the connecting holes 103 on the support base 1. Fastening screws 3 are then screwed into the screw holes 203 and connecting holes 103 in sequence, until the head of the fastening screw 3 is completely flush with the upper surface of the pipe fixing slot 2. At this point, 1-2 turns of thread should be reserved for locking, ensuring that the pipe fixing slot 2 can rotate freely around the fastening screw 3. This completes the initial positioning process of the pipe fixing slot 2. The positioning process provides a degree of freedom for the rotation of the fastening screw 3, allowing installers to make fine adjustments according to the actual pipe routing in subsequent steps. This is suitable for situations where there is a deviation between the theoretical and actual pipe design positions, thereby compensating for manufacturing and assembly errors.

[0032] 3. Adjustment of pipe fixing groove 2 angle and pipe fixing: Based on the above preliminary positioning structure, each pipe fixing groove 2 can be independently rotated and adjusted around the fastening screw 3. According to actual measurement, the maximum rotation range of a single pipe fixing groove 2 is ±30°, that is, a maximum clockwise rotation angle of 30° and a maximum counterclockwise rotation angle of 30°. Two pipe fixing grooves 2 can cooperate by rotating in opposite or the same direction to achieve a pipe angle adaptation range of up to ±60°. The above-mentioned independent adjustment range of ±30° covers the common angle deviations in vehicle piping systems, which can fully meet the installation requirements of non-parallel pipe layout 5 of most passenger car models and commercial vehicles, expand the scope of application, and realize the universalization and platformization of parts.

[0033] The specific adjustment and fixing steps for different pipeline layouts are as follows: For details on the compatibility of this device with parallel pipe 4, please refer to [reference needed]. Figure 3 If the two pipes to be fixed are arranged in parallel, rotate the two pipe fixing grooves 2 respectively to ensure that the center lines of the two U-shaped grooves remain parallel, so that the parallelism error is ≤0.5mm. Then, align the pipes with the corresponding U-shaped grooves and press the pipes to pass through the clamping teeth 202202, so that they are fully engaged with the U-shaped grooves without any local suspension or looseness. For parallel pipes, it is only necessary to adjust the center lines of the U-shaped grooves of the two pipe fixing grooves 2 to keep them parallel, ensuring that the pipes are in a natural state after fixing without torsional stress; thus ensuring uniform contact between the pipes and the fixing grooves.

[0034] For the compatibility of this device with non-parallel pipe 5, please refer to the following for details. Figure 4If the two pipes to be fixed are arranged at an angle, such as 30° to 60°, rotate the two pipe fixing grooves 2 respectively to ensure that the angle between the center lines of the two U-shaped grooves is consistent with the included angle of the pipes. Then, align the pipes with the corresponding U-shaped grooves and press the pipes to pass through the locking teeth 202, ensuring complete engagement with the U-shaped grooves without any local suspension or looseness. This ensures that the pipes are in a stress-free state within the fixing grooves. The angle matching design avoids stress concentration caused by the forced bending of pipes in traditional one-piece fixing grooves, protecting the integrity of the pipe structure and extending the service life of the pipes. If pipe replacement is needed, simply release the fastening screws 3 on the pipe fixing groove 2 corresponding to the pipe to be replaced.

[0035] 4. Final Locking and Anti-Loosening Treatment of Pipe Fixing Groove 2: After the pipe is installed in place, use a torque wrench to continue tightening the fastening screws 3 until they are fully tightened. During the tightening process, continuously observe the stress state of the pipe fixing groove 2 to ensure that it is evenly pressed against the lower support surface 106 of the support base 1, without any one-sided lifting or uneven stress. To improve the vibration resistance of the device during vehicle operation, flat washers and spring washers can be added between the head of the fastening screw 3 and the contact surface of the pipe fixing groove 2, or thread-locking adhesive can be evenly applied to the screw threads to prevent the screws from loosening due to vibration during vehicle operation. For vehicles used in humid and hot environments, stainless steel fastening screws 3 can be selected to enhance the corrosion and rust resistance of the device. After assembly, manually shake the pipe to confirm that the pipe is not loose or has no obvious shaking, then the installation is complete.

[0036] In this embodiment, the angle adjustment of the pipe fixing groove 2 requires no additional tooling, making operation convenient; its independent adjustment design adapts to different pipe layouts, offering strong versatility; the cooperation between the clamping teeth 202 and the anti-loosening structure effectively improves the stability and durability of pipe fixing, making it widely applicable to the installation and fixing of pipe systems in various vehicle types, including passenger cars and commercial vehicles. In the assembly of automotive pipe systems (such as fuel lines, brake lines, and cooling lines), this device can integrate and constrain two pipes, reducing pipe vibration, noise, and preventing pipe wear; during vehicle operation, it can adapt to the relative displacement caused by vibration and temperature changes in the pipes, preventing loosening, wear, or even failure after long-term use, thereby ensuring the reliability and safety of the entire vehicle's piping system.

[0037] This mini-truck dual-groove pipe fixing device features an adjustable pipe fixing groove 2 that requires no additional tooling, making it easy to operate. Its independent adjustment design adapts to different pipe layouts, offering strong versatility. The combination of the clamping teeth 202 and the anti-loosening structure effectively enhances the stability and durability of the pipe fixing. It solves the problems of existing dual-groove pipe fixing devices being unable to adapt to non-parallel or interfering pipes, failing to meet the fixing requirements of different vehicle models and pipe diameters, and having low assembly and disassembly efficiency.

[0038] In summary, the dual-groove pipe fixing device and installation method for mini-trucks have the following advantages: 1. High Adaptability and Economy: The device boasts exceptional adaptability and compatibility. Its core advantage lies in the independent angular rotation of the two pipe fixing slots 2, allowing for free adjustment of the combined angle according to the actual pipe layout. This not only accommodates parallel automotive pipe layouts but also flexibly meets the installation and fixing needs of non-parallel pipes 5 at angles of 30°-60°. This solves the industry pain point of traditional fixing devices being unable to adapt to non-parallel pipe layouts 4 in vehicle piping systems, significantly improving the product's installation compatibility. Adopting a flexible and adjustable structural design, the device eliminates the need for separately designed fixing components for different vehicle models' pipe layouts, achieving universal adaptability across multiple vehicle models and pipe layouts. This reduces investment in developing dedicated molds, lowers production and inventory management costs, significantly expands the product's applicability, and enhances its market competitiveness.

[0039] 2. Enhanced Efficiency and Flexibility in Installation and Maintenance: The installation and disassembly process of the device is convenient and efficient, requiring no complex auxiliary tools such as welding equipment or specialized positioning fixtures. Operators can complete the overall assembly and disassembly operations using only a conventional torque wrench. More importantly, the device adopts a modular design, with a detachable connection between the pipe fixing groove 2 and the support base 1. When it is necessary to adapt to pipes of different diameters, there is no need to disassemble the support base 1 again; simply replacing the pipe fixing groove 2 with the corresponding specification is sufficient for adaptation and adjustment. This precisely meets the fixing requirements of various types and diameter pipes such as automotive fuel pipes, brake pipes, and cooling pipes, significantly improving the flexibility of the device and significantly shortening the operation time for subsequent pipe maintenance and replacement, effectively optimizing the assembly efficiency and after-sales maintenance efficiency of the vehicle production line.

[0040] 3. Simplified Structure and Stable Performance: The device adheres to the principle of simplification without sacrificing functionality in its structural design. It abandons the complex multi-link adjustment mechanisms and redundant auxiliary positioning components of traditional fixing devices. The core functional requirement of fixing automotive pipelines is achieved through a simple structure of support base 1 and an independent adjusting and fixing groove. The constraint of the clamping teeth 202, the anti-loosening design of the fastening screws 3, and the precise fit between support base 1 and the vehicle body, all contribute to ensuring the stability and reliability of the connection between the pipeline and the fixing device, and between the device and the vehicle body, while simplifying the structure. This enhances the product's practicality, economy, and adaptability.
