Description

Technical Field

[0001] This utility model relates to the technical field of rigid pipe clamping devices, specifically to an adjustable pipe diameter rigid pipe clamp and a vehicle. Background Technology

[0002] Brake hose clamps are crucial components in automotive assembly, used to secure brake hoses in hydraulic braking systems to the vehicle body or other parts. Automotive suppliers typically standardize brake hoses based on their diameter, quantity, and installation location for ease of design, management, and assembly. However, the corrosion resistance requirements for brake hoses vary from 1000 to 3000 hours. To achieve higher corrosion resistance, it's often necessary to replace the surface coating or increase its thickness, resulting in a larger brake hose diameter (the tolerance for the same diameter series is generally around 0.5mm). Using smaller diameter clamps can easily lead to improper installation, weak connections, and detachment. Developing new clamps would increase the variety of clamp types, making identification of similar structural components difficult and increasing the risk of incorrect installation, thus raising management costs. Utility Model Content

[0003] One objective of this utility model is to provide an adjustable pipe clamp for rigid pipes, so as to solve the technical problem that the existing pipe clamps cannot adapt to different rigid pipe diameters. Another objective is to provide a vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows.

[0005] Adjustable diameter rigid pipe clamp, comprising:

[0006] The base includes a support part, a first upright plate and a second upright plate. The top of the support part is recessed inward to form a cylindrical bearing area. A hollow groove is formed in the middle of the bearing area. The first upright plate and the second upright plate are arranged opposite each other on both sides of the bearing area.

[0007] The left and right grippers are both located between the first and second upright plates. The left gripper extends from the end of the first upright plate away from the support portion toward the support portion, and the right gripper extends from the end of the second upright plate away from the support portion toward the support portion. As they gradually approach the support portion, the distance between the left and right grippers gradually decreases.

[0008] An elastic cantilever has one end connected to the base and the other end extending into the hollow groove to form a free end. The free end has a supporting part that protrudes from the hollow groove in its natural state.

[0009] Through the above technical means, the inverted V-shaped clamps combined with the deformable design of the elastic cantilever can accommodate pipe diameter variations within a certain range, reducing assembly misalignment or detachment problems caused by pipe diameter changes; for pipe diameter variations caused by different coating thicknesses, there is no need to replace the pipe clamps, reducing development and management costs; the installation process is a press-in type, with the clamps and elastic cantilever automatically completing reset and clamping, making operation simple and the clamping reliable; the load-bearing area and the elastic cantilever work together to limit and constrain the displacement path of the rigid pipe, preventing excessive displacement of the rigid pipe under dynamic conditions such as external impact or vehicle vibration.

[0010] Furthermore, the end face shape of the support portion away from the elastic cantilever, the end face shape of the left gripper facing the support portion, and the end face shape of the right gripper facing the support portion are all arc-shaped surfaces.

[0011] Through the above technical means, a support and clamping structure with three or nearly surface contacts is formed during the clamping process of the rigid tube. This not only enhances the stability and uniformity of the clamping, but also effectively disperses the contact pressure per unit area during the clamping process, reducing the risk of indentation or damage to the surface of the rigid tube.

[0012] Furthermore, the left and right grippers are symmetrically arranged, and the support portion is directly opposite the opening area between the left and right grippers.

[0013] By employing the above technical methods, a three-point support structure is constructed, enabling the clamping structure to provide limiting effects in multiple directions. This effectively reduces the possibility of the rigid tube sliding or swaying when subjected to vibration or impact.

[0014] Furthermore, a weight-reducing cavity is formed inside the support portion, and the hollowed-out groove is connected to the weight-reducing cavity.

[0015] The above technical methods effectively reduce the structural weight of the rigid pipe clamp, thereby improving the overall vehicle lightweighting level, especially suitable for new energy vehicles, light vehicles, and other models where quality control is more sensitive. Since the free end of the elastic cantilever extends into the hollow groove, and the supporting part may further enter the hollow groove when subjected to rigid pipe pressure or structural vibration, connecting the hollow groove to the weight-reduction cavity can further release the maximum deformation space of the elastic cantilever, avoiding early deformation failure due to "bottoming out" under extreme working conditions, and improving the reliability and clamping adaptability of the elastic structure.

[0016] Furthermore, an elastic element is provided inside the weight reduction cavity, and the elastic element is configured to generate a driving force on the elastic cantilever in the direction of the left gripper and the right gripper.

[0017] Through the above technical means, the elastic component not only enhances the impact resistance of the elastic cantilever, but also provides additional restoring driving force and vibration-resistant support force when the elastic cantilever undergoes significant deformation due to complex working conditions. This effectively reduces the overall displacement of the rigid tube within the clamping structure, ensuring the long-term stability and clamping reliability of the system. Furthermore, the elastic component is located within the weight-reduction cavity, which does not affect the overall contour of the clamping structure and facilitates integration in mold design and assembly processes, balancing strength, performance, and ease of processing.

[0018] Furthermore, a support plate is provided inside the weight reduction cavity, and the support plate is connected to the two inner walls of the weight reduction cavity. The elastic element is disposed between the elastic cantilever and the support plate.

[0019] Through the above technical means, the setting of the support plate can effectively prevent the elastic element from becoming unstable or shifting in the weight reduction cavity, maintain the constancy of its force transmission direction, and thus improve the reliability and durability of the clamping system under multiple impacts and vibrations.

[0020] Furthermore, the support plate has a threaded hole facing the elastic cantilever, and an adjusting bolt is screwed into the threaded hole. The elastic element is disposed between the elastic cantilever and the support plate.

[0021] By using the above technical means, and by setting threaded holes on the support plate and cooperating with adjusting bolts, the compression state of the elastic element can be precisely adjusted, thereby controlling the magnitude of the thrust of the elastic element on the elastic cantilever. The screwing depth of the adjusting bolt can change the pre-compression of the elastic element, thereby adjusting the clamping force of the elastic cantilever on the rigid tube, and thus achieving adaptability to rigid tube structures with different stiffness levels or vibration isolation requirements.

[0022] Furthermore, the base also includes a third upright plate, a top plate, and a bottom plate. The third upright plate is positioned opposite the second upright plate, and the second upright plate is located between the first upright plate and the third upright plate. The top plate connects the top ends of the second upright plate and the third upright plate, and the bottom plate connects the bottom ends of the second upright plate and the third upright plate. A first fixing hole is provided on the bottom plate, and a second fixing hole is provided on the top plate, which is opposite to the first fixing hole.

[0023] The above technical means facilitate the reliable installation of this rigid pipe clamp on the vehicle body, chassis bracket, mounting plate or other fixed device using common fasteners such as bolts, screws, and rivets.

[0024] Furthermore, each of the second and third upright plates has a snap-fit ​​component on one of its opposite surfaces. The snap-fit ​​component includes a neck, a head, and fixing teeth connected in sequence. The neck is connected to the second or third upright plate and extends in a direction away from the second or third upright plate to which it is connected. The head extends from the end of the neck in a direction toward the top plate. The fixing teeth are arranged in multiple rows and are located on the side of the head away from the neck.

[0025] The above technical means enable rapid assembly and anti-retraction of mounting bolts, and also allow for tool-free installation, easy maintenance and replacement. It has significant advantages such as simple structure, convenient installation, and high reliability, and is particularly suitable for scenarios with limited structural space or frequent disassembly and assembly.

[0026] Furthermore, the snap-fit ​​members are arranged in multiple rows along the axial direction of the first fixing hole.

[0027] The above technical means further enhance the holding stability and anti-detachment ability of the snap-fit ​​component for the mounting bolts. When facing large impact loads or vibration conditions, it effectively disperses the force and prevents the mounting bolts from loosening or falling off.

[0052] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0053] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0054] like Figure 1-10 As shown, this embodiment presents an adjustable-diameter rigid pipe clamp and a vehicle using the clamp. This adjustable-diameter rigid pipe clamp is suitable for installing brake rigid pipes 910 in a vehicle's integrated hydraulic braking system, and is particularly suitable for rigid pipes 910 with a certain tolerance range (e.g., within 0.5mm). The rigid pipe clamp mainly comprises a base 100, a left clamp 200, a right clamp 300, and an elastic cantilever 400.

[0055] The base 100 includes a support portion 110, a first upright plate 120, and a second upright plate 130. The top of the support portion 110 is recessed inward to form a cylindrical bearing area 111. A hollow groove 112 is formed in the middle of the bearing area 111. The first upright plate 120 and the second upright plate 130 are arranged opposite each other on both sides of the bearing area 111. A left gripper 200 and a right gripper 300 are both located between the first upright plate 120 and the second upright plate 130. The left gripper 200 is located away from the first upright plate 120 from the support portion 110. One end extends toward the support portion 110, and the right gripper 300 extends toward the support portion 110 from the end of the second upright plate 130 away from the support portion 110. As it gradually approaches the support portion 110, the distance between the left gripper 200 and the right gripper 300 gradually decreases. One end of the elastic cantilever 400 is connected to the base 100, and the other end extends into the hollow groove 112 to form a free end. The free end forms a support portion 410. In its natural state, the support portion 410 protrudes from the hollow groove 112.

[0056] The left jaw 200 and right jaw 300 form an inverted V-shape, with their openings facing upwards. The distance between them is smaller near the support 110 and larger further away. The support portion 410 on the free end of the elastic cantilever 400 provides effective support and clamping force to the bottom of the rigid tube 910 after the jaws clamp it. In its natural state, the support portion 410 protrudes beyond the slot 112, enabling it to actively contact the rigid tube 910. The slot 112 releases processing stress, facilitates the movement of the elastic cantilever 400, and further enhances the overall elasticity and obstacle avoidance capabilities of the device.

[0057] During use, when a brake tube 910 is inserted through the opening between the grippers, as the pressing force increases, the left gripper 200 and right gripper 300, due to their elastic materials or structural design, are compressed and open at a certain angle to allow the tube 910, whose diameter is larger than the opening distance, to pass through. After the tube 910 enters below the grippers, the grippers automatically return to their original position, and their upper ends exert downward pressure on the tube 910. At the same time, the lower surface of the tube 910 presses against the support portion 410 of the elastic cantilever 400, causing the support portion 410 to deform and deflect downwards or outwards, generating deformation stress and thus providing an upward spring-loaded clamping force. Finally, the tube 910 is stably clamped in the support structure formed by the left gripper 200, right gripper 300, and elastic cantilever 400.

[0058] Compared with existing technologies, the rigid pipe clamp provided in this embodiment has the following advantages: The inverted V-shaped clamping jaws, combined with the deformable design of the elastic cantilever 400, can accommodate pipe diameter variations within a certain range for the rigid pipe 910, reducing assembly misalignment or detachment problems caused by diameter changes; no clamp replacement is required for pipe diameter variations caused by different coating thicknesses, reducing development and management costs; the installation process is press-fit, with the clamping jaws and elastic cantilever 400 automatically resetting and clamping, making operation simple and the clamping reliable. In summary, this embodiment provides a structurally sound, reusable, and highly adaptable adjustable pipe diameter rigid pipe clamp, solving the problems of insecure clamping and misassembly caused by variations in the coating thickness of the rigid pipe 910, reducing manufacturing and management costs while ensuring clamping reliability.

[0059] Although the design of the elastic cantilever 400 enables the rigid pipe clamp to be compatible with rigid pipes 910 of different diameters, due to the inherent characteristics of the elastic cantilever 400, it will deform to some extent when the overall structure is subjected to a certain external impact or vibration, causing the clamped rigid pipe 910 to displace within a certain range. The structural design of the support portion 110 in this embodiment can specifically address the above-mentioned problem in actual use to achieve a certain degree of impact resistance stability.

[0060] In the above embodiment, the bearing area 111 formed by the recess on the support part 110 is to limit the excessive displacement of the rigid tube 910. The elastic cantilever 400 extends in the hollow groove 112 in the bearing area 111. When the structure is impacted or vibrated, if the deformation of the elastic cantilever 400 is too large, the support part 410 enters the hollow groove 112. At this time, the bearing area 111 will directly contact the rigid tube 910, limiting the further displacement of the rigid tube 910 and avoiding excessive displacement of the rigid tube 910.

[0061] Specifically, the top of the support portion 110 is configured as an inwardly recessed cylindrical structure, forming a bearing area 111 for limiting positioning. This bearing area 111 works in conjunction with the elastic cantilever 400 to prevent excessive displacement of the rigid tube 910 under dynamic conditions such as external impact or vehicle vibration. In its natural state, the support portion 410 at the free end of the elastic cantilever 400 protrudes outside the hollow groove 112 in the middle of the bearing area 111, effectively supporting the bottom of the rigid tube 910 and providing clamping force. However, when the structure is subjected to a large impact load or continuous vibration, the elastic cantilever 400 may undergo significant elastic deformation. In this case, the support portion 410 will rebound into the hollow groove 112 under the action of external force, resulting in a certain degree of displacement. Under these circumstances, as the rigid tube 910 sinks, it will come into contact with the bearing area 111 formed by the recessed cylindrical surface. Because the cylindrical surface has a covering and restricting effect, it can limit and constrain the displacement path of the rigid tube 910, thereby preventing excessive shaking or detachment of the rigid tube 910 due to the large deformation of the elastic cantilever 400. Therefore, through the structural design of the bearing area 111 of this limiting type, the rigid tube clamp is compatible with different pipe diameters while also possessing excellent impact and vibration resistance, further improving the clamping stability and safety under actual use conditions.

[0062] In some embodiments, in order to further improve the fitting stability of the rigid tube 910 clamping structure and its adaptability to rigid tubes 910 of different specifications, the end face shape of the support portion 410 away from the elastic cantilever 400, the end face shape of the left gripper 200 facing the support portion 110, and the end face shape of the right gripper 300 facing the support portion 110 are all arc-shaped surfaces.

[0063] Specifically, the end face of the support portion 410 adopts a concave arc-shaped structure that matches the outer surface of the rigid tube 910, so as to fully fit its lower surface when the rigid tube 910 is clamped. The ends of the left jaw 200 and the right jaw 300 facing the support portion 110 are also designed as arc-shaped curved surfaces, so as to form a semi-enclosed clamping contact above the rigid tube 910. Through the combined action of the above three arc-shaped surfaces, a support clamping structure with three surface contacts or close to surface contacts is formed during the clamping of the rigid tube 910. This not only enhances the stability and uniformity of clamping, but also effectively disperses the contact pressure per unit area during clamping, reducing the risk of indentation or damage to the surface of the rigid tube 910.

[0064] In some preferred embodiments, the end faces of the left gripper 200, right gripper 300, and support portion 410 are respectively provided with elastic pads to further enhance clamping adaptability and protective performance. Specifically, the pads can be made of rubber, foamed plastic, silicone, or other elastic materials with certain flexibility and resilience, and their thickness can be selected according to the pipe diameter range of the rigid tube 910, clamping force requirements, and environmental durability requirements. This pad, located on the end faces of the left gripper 200, right gripper 300, and support portion 410, can form a more sufficient surface contact with the outer surface of the rigid tube 910, thereby maintaining a stable and reliable clamping effect even when the rigid tube 910 has a certain surface roughness, uneven coating, or pipe diameter tolerance variation. During clamping, the elastic pads can undergo slight deformation under stress to compensate for geometric errors caused by the rigidity of the structural hardware, ensuring that the clamping surface fully conforms to the cylindrical surface of the rigid tube 910, further improving clamping stability and shock absorption. Especially under vibration and impact loads during vehicle operation, the elastic pad can absorb some of the dynamic energy, playing a buffering and vibration reduction role, effectively reducing the risk of relative displacement between the rigid tube 910 and the clamping structure, and extending the service life of the system. In addition, the pad also has a certain anti-wear effect, which can reduce the local wear problem on the surface of the rigid tube 910 caused by long-term clamping contact.

[0065] In some embodiments, the left gripper 200 and the right gripper 300 are symmetrically arranged, and the support portion 410 is directly opposite the opening area between the left gripper 200 and the right gripper 300.

[0066] The rigid tube 910 is clamped in a wraparound manner using a symmetrically arranged gripper structure. The left gripper 200 and right gripper 300 maintain consistency in shape, size, and material rigidity, and are arranged symmetrically around the central axis of the rigid tube 910. This provides a balanced lateral clamping force during clamping, preventing tilting or stress concentration of the rigid tube 910 due to uneven clamping force. The support portion 410 is located directly below the opening between the left gripper 200 and right gripper 300, forming the "bottom support point" in the three-point support structure. Combined with the "lateral clamping point" provided by the left gripper 200 and right gripper 300, the clamping structure provides limiting functionality in multiple directions. The support portion 410 is directly opposite the opening between the left gripper 200 and right gripper 300, causing the lines connecting the ends of the left gripper 200, the right gripper 300, and the midpoint of the support portion 410 to form or nearly form an isosceles triangle. The introduction of this isosceles triangle structure helps to maintain the symmetry and balance of forces during clamping, enhances the stability of the clamping structure, and thus effectively reduces the possibility of the rigid tube 910 sliding or swaying when subjected to vibration or impact.

[0067] In some embodiments, a weight-reducing cavity 113 is formed inside the support portion 110, and the hollowed-out groove 112 is connected to the weight-reducing cavity 113. The weight-reducing cavity 113 can be formed inside the support portion 110 by one-time injection molding or post-processing, and its structure is usually a hollow cavity. It can be a closed cavity or a partially open cavity, depending on the product strength requirements.

[0068] Specifically, the design of connecting the weight-reducing cavity 113 with the hollowed-out groove 112 can effectively reduce the structural weight of the rigid pipe clamp while maintaining the overall rigidity of the support part 110, thereby improving the overall lightweight level of the vehicle. This is especially suitable for new energy vehicles, light vehicles, and other models where quality control is more sensitive. Since the free end of the elastic cantilever 400 extends into the hollowed-out groove 112, and the support part 410 may further enter the hollowed-out groove 112 when subjected to pressure from the rigid pipe 910 or structural vibration, connecting the hollowed-out groove 112 with the weight-reducing cavity 113 can further release the maximum deformation space of the elastic cantilever 400, avoiding the problem of early deformation failure of the elastic cantilever 400 due to "bottoming out" under extreme working conditions, and improving the reliability of the elastic structure and the clamping adaptability range.

[0069] Although the cylindrical bearing area 111 formed by the recess on the support 110 can limit the position of the rigid tube 910 to its extreme position and prevent excessive vibration, in high-demand applications, it is still necessary to further limit the impact deformation of the elastic cantilever 400. Based on this, such as Figure 7 and 8As shown, in some embodiments, an elastic element 500 is provided within the weight-reducing cavity 113. The elastic element 500 is configured to generate a driving force on the elastic cantilever 400 in the direction of the left gripper 200 and the right gripper 300. Specifically, the elastic element 500 can be in the form of a compression spring, a wave spring, or a rubber pad, with one end supported by a fixed structure within the weight-reducing cavity 113 and the other end abutting against the region of the elastic cantilever 400 near its free end. In its natural state, the elastic element 500 does not undergo significant deformation. As the rigid tube 910 is pressed in, causing the elastic cantilever 400 to deform downwards, the elastic element 500 is also compressed, storing elastic energy and limiting the vibration of the rigid tube 910 caused by external impact. When the external impact is eliminated or the vibration of the rigid tube 910 tends to weaken, the elastic element 500 releases energy, applying a reverse rebound force to the elastic cantilever 400, thereby providing additional upward force. Through this design, the elastic element 500 not only enhances the impact resistance of the elastic cantilever 400, but also provides additional restoring driving force and vibration-resistant support force when the elastic cantilever 400 undergoes significant deformation due to complex working conditions. This effectively reduces the overall displacement of the rigid tube 910 within the clamping structure, ensuring the long-term stability and clamping reliability of the system. Furthermore, the elastic element 500 is located within the weight-reduction cavity 113, which does not affect the overall contour of the clamping structure and facilitates integration in mold design and assembly processes, balancing strength, performance, and ease of processing.

[0070] In some implementations, such as Figure 7-8 As shown, a support plate 600 is disposed within the weight-reducing cavity 113. The support plate 600 is connected to the two opposing inner walls of the weight-reducing cavity 113. The elastic element 500 is disposed between the elastic cantilever 400 and the support plate 600. The support plate 600 extends along the transverse direction of the support portion 110 and is fixedly connected to the two opposing inner walls of the weight-reducing cavity 113, forming a spanning structural support. The elastic element 500 is disposed between the elastic cantilever 400 and the support plate 600, and is preferably in a compressed pre-tightened state. In this embodiment, the support plate 600 can be made of metal plate or reinforced engineering plastic plate, possessing good rigidity and fatigue resistance. One end of the elastic element 500 abuts against the lower surface of the free end of the elastic cantilever 400 or a position near the free end, while the other end abuts against the upper surface of the support plate 600, thereby constructing an elastic support unit within a confined space. When the rigid tube 910 is pressed into the clamping space and the elastic cantilever 400 is deformed, the elastic element 500 is compressed and stores elastic energy. As the impact weakens or the load is released, the elastic element 500 gradually releases energy, pushing the elastic cantilever 400 to rebound towards the left jaw 200 and the right jaw 300, providing stable support for the rigid tube 910.

[0071] The support plate 600 can effectively prevent the elastic element 500 from becoming unstable or shifting in the weight reduction cavity 113, and maintain the constancy of its force transmission direction, thereby improving the reliability and durability of the clamping system under multiple impacts and vibrations.

[0072] In some preferred embodiments, the support plate 600 is preferably integrally formed with the support portion 110, for example, by injection molding, casting, or integral stamping to form an integrated structure. By integrating the support plate 600 with the support portion 110, not only can assembly steps and manufacturing costs be reduced, but the overall rigidity and stability of the structure can also be significantly improved. The support plate 600 adopts a transverse design, with its two ends respectively connected to the opposing inner walls of the weight-reducing cavity 113, forming a beam-like structure. While providing support for the elastic element 500, it also serves as a structural reinforcement member. This transverse bridging method can significantly improve the bending stiffness and compressive strength of the support portion 110, enhance the structural stability of the entire rigid pipe clamp under load, and effectively address vibration fatigue or deformation problems that may occur during long-term use.

[0073] In some implementations, such as Figure 9-10 As shown, the support plate 600 has a threaded hole 610 facing the elastic cantilever 400, and an adjusting bolt 700 is screwed into the threaded hole 610. The elastic element 500 is disposed between the elastic cantilever 400 and the support plate 600.

[0074] By providing threaded holes 610 on the support plate 600 and using adjusting bolts 700, the compression state of the elastic element 500 can be precisely adjusted, thereby controlling the magnitude of the thrust of the elastic element 500 on the elastic cantilever 400. The end of the adjusting bolt 700 can directly abut against the elastic element 500; for example, the bolt head 820 can be designed as a flat or hemispherical shape to accommodate the compression deformation of the elastic element 500 and ensure uniform and reliable force transmission.

[0075] In this embodiment, the screw depth of the adjusting bolt 700 can change the pre-compression of the elastic element 500, thereby adjusting the clamping force of the elastic cantilever 400 on the rigid pipe 910, thus achieving adaptability to rigid pipe 910 structures with different stiffness levels or vibration isolation requirements. This structure is particularly suitable for scenarios with high clamping stability requirements, complex vibration environments, or large variations in pipe load.

[0076] In some implementations, such as Figure 1-10The base 100 further includes a third upright plate 140, a top plate 160, and a bottom plate 150. The third upright plate 140 is directly opposite to the second upright plate 130, and the second upright plate 130 is located between the first upright plate 120 and the third upright plate 140. The top plate 160 connects the top ends of the second upright plate 130 and the third upright plate 140, and the bottom plate 150 connects the bottom ends of the second upright plate 130 and the third upright plate 140. The bottom plate 150 has a first fixing hole 151, and the top plate 160 has a second fixing hole 161 that is directly opposite to the first fixing hole 151.

[0077] This embodiment achieves structural closure between the second upright plate 130 and the third upright plate 140, forming a frame-like box structure for the entire base 100. The connection between the top plate 160 and the bottom plate 150 enhances the structure's bending stiffness and vibration resistance. The first fixing hole 151 and the second fixing hole 161 serve as fixing channels penetrating the upper and lower structures, facilitating the reliable installation of the rigid pipe clamp onto the vehicle body, chassis bracket, mounting plate, or other fixing devices using common fasteners such as bolts, screws, and rivets. Preferably, the central axes of the first fixing hole 151 and the second fixing hole 161 are coaxial to ensure...

[0078] In some embodiments, a snap-fit ​​member 800 is provided on the opposite side surface of the second upright plate 130 and the third upright plate 140. The snap-fit ​​member 800 includes a neck 810, a head 820 and a fixing tooth 830 connected in sequence. The neck 810 is connected to the second upright plate 130 or the third upright plate 140 and extends in a direction away from the second upright plate 130 or the third upright plate 140 to which it is connected. The head 820 extends from the end of the neck 810 in a direction toward the top plate 160. The fixing tooth 830 is provided in multiple rows and is located on the side of the head 820 opposite to the neck 810.

[0079] The snap-fit ​​component 800 in this structural design is used to form a mechanical engagement with the threads of the mounting bolt, achieving self-locking and further improving assembly efficiency and connection stability. Specifically, during installation, the mounting bolt is inserted through the first fixing hole 151 on the base plate 150, passing through the space between the second upright plate 130 and the third upright plate 140. When the mounting bolt is inserted into the area between the two opposing snap-fit ​​components 800, because the distance between the two snap-fit ​​components 800 is designed to be slightly smaller than the diameter of the bolt, the mounting bolt will force the snap-fit ​​component 800 to deform to a certain extent during insertion. During this process, the head 820 of the snap-fit ​​component 800 forms a necked structure due to its flexible connection with the neck 810, and the head 820 will undergo a backward tilting displacement deformation, allowing the mounting bolt to pass smoothly through the necked structure. Once the mounting bolt is fully inserted, the head 820 automatically resets under the elasticity of the material, and the fixing teeth 830 embed into the threaded groove of the mounting bolt, thus forming a fixing tooth 830-thread engagement structure, achieving a locking function to prevent the mounting bolt from retracting. Preferably, the fixing teeth 830 are arranged in multiple rows to enhance the engagement with the thread.

[0080] This structure, by setting up a snap-fit ​​component 800 that can be elastically deformed, and setting a fixing tooth 830 for engaging the thread at its head 820, not only realizes the rapid assembly and limiting anti-retraction of the mounting bolt, but also allows for tool-free installation and easy maintenance and replacement. It has significant advantages such as simple structure, convenient installation, and high reliability, and is particularly suitable for scenarios with limited structural space or that require frequent disassembly and assembly.

[0081] In some embodiments, the snap-fit ​​members 800 are arranged in multiple rows along the axial direction of the first fixing hole 151. This design, by arranging multiple snap-fit ​​members 800 in the axial direction of the first fixing hole 151 (i.e., the direction of bolt insertion), further enhances the holding stability and anti-disengagement capability of the snap-fit ​​members 800 for the mounting bolt. Multiple rows of snap-fit ​​members 800 allow more fixing teeth 830 to engage in the threaded grooves, and also form a multi-point distributed limiting structure along the axial direction, thereby effectively dispersing the force and preventing the mounting bolt from loosening or falling off when facing large impact loads or vibration conditions. Specifically, each row of snap-fit ​​members 800 includes a neck 810, a head 820, and fixing teeth 830, and is attached to the inner surface of the second upright plate 130 and the third upright plate 140, arranged along the bolt insertion path. The multiple fixing teeth 830 form a series-like interlocking locking effect in the axial direction, providing distributed clamping force.
