Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, in particular to a shock-absorbing pipe clamp matched with a mushroom nail. Background Art

[0002] Traditionally, plastic pipe clamps connect to the vehicle body through through-holes, threaded holes, or welded studs in the sheet metal. However, to simplify the process and improve production efficiency, cast aluminum bodies now feature integrated polished holes (eliminating the tapping process) or tapered polished posts (instead of welded studs). These traditional plastic pipe clamps are no longer suitable for this type of connection. Conventional shock-absorbing pads require the development of separate molds, which are then molded on two injection molding machines and then assembled. Alternatively, a two-color mold can be developed for rotary two-color injection molding (a rotary two-color mold requires the development of two molds).

[0003] Chinese invention patent publication number CN210687274U discloses an isolation and shock-absorbing pipe clamp. The clamp comprises a pipe clamp body with two symmetrically positioned slots. A through-hole is provided in the center of the clamp body. A first retaining rib and a second retaining rib are provided on the inner wall of the through-hole, sequentially from top to bottom. A shock-absorbing rubber pad is secured within the through-hole, with the upper end surface of the pad protruding from the upper end surface of the clamp body. A bolt clip is sleeved within the pad, with a first retaining block provided on the bolt clip. The present invention utilizes the clamp body, shock-absorbing rubber pad, and bolt clip to simultaneously isolate and shock-absorb pipeline vibrations, clamp vibrations, and vibrations between the clamp and the vehicle body, thereby reducing operating costs.

[0004] However, traditional pipe clamps cannot be clamped and fixed when connected to blind holes / plain wall columns of cast aluminum body, and the shock-absorbing rubber pads require multiple molds to produce and are complicated to assemble. Summary of the Invention

[0005] The purpose of the present invention is to provide a shock-absorbing pipe clamp that cooperates with mushroom nails, aiming to solve the problems that traditional pipe clamps cannot be clamped and fixed when connected to blind holes / plain wall columns of cast aluminum car bodies, and the shock-absorbing rubber pads require multiple molds for production and complex assembly technology.

[0006] The present invention is implemented as follows: a shock-absorbing pipe clamp for use with mushroom nails, comprising a pipe clamp shell, characterized in that the pipe clamp shell is a mirror-symmetrical structure, and the pipe clamp shell has two symmetrically arranged through holes from top to bottom, each of the through holes is provided with a pair of shock-absorbing rubber pads, a placement groove with a stepped hole structure is provided in the middle of the pipe clamp shell, a metal claw is detachably clamped in the placement groove, a column hole is provided in the center of the bottom of the pipe clamp shell, and the metal claw is coaxial with the column hole.

[0007] Furthermore, there are two symmetrically arranged protrusions in the middle of the placement groove, and the outer wall of the metal claw is provided with four annular grooves evenly distributed, and the two symmetrically distributed groove protrusions are engaged and snap-fitted.

[0008] Furthermore, a buffer block coaxial with the placement slot is provided at the bottom of the placement slot.

[0009] Furthermore, there are symmetrically arranged flip hinge plates in the middle of both sides of the tube clamp shell, and the extending ends of the flip hinge plates away from the column hole are hook-shaped hook plates. There are two symmetrically arranged card plates at the bottom of the buffer block, and the hook plates are buckled with the card plates. The clamping direction of the hook plates and the card plates is perpendicular to the axial direction of the column hole.

[0010] Furthermore, the inner walls of the through holes are provided with symmetrically distributed shock-absorbing slots, and the outer walls of the shock-absorbing rubber pads are provided with two symmetrically arranged shock-absorbing blocks, which are clamped in the shock-absorbing slots.

[0011] Furthermore, the inner side of the shock-absorbing rubber pad is provided with anti-slip strips that are evenly spaced.

[0012] Furthermore, the pipe clamp housing, the buffer block and the clamping plate are an integrally formed structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This shock-absorbing pipe clamp used with mushroom nails achieves multiple advantages through ingenious design: the pipe clamp shell adopts mirror symmetry and coaxial layout, which is suitable for mushroom nail installation. The double through-holes support multiple pipelines in parallel. The one-piece molded structure strengthens rigidity and reduces assembly gaps. The shock-absorbing rubber pad is axially limited by the card slots and blocks, the inner anti-slip strip increases friction and prevents slipping, and its own elasticity absorbs vibration to achieve pipeline stability and shock absorption. The metal claws are circumferentially prevented from rotating by protrusions and grooves, and the buffer block is axially buffered to ensure accurate and stable connection with the mushroom nail. During assembly, the various parts are quickly adapted through card slots, protrusions, etc., and the locking structure enhances stability. Maintenance allows for convenient replacement of pipelines and parts, reducing costs. The overall structure takes into account reliable structure, complete functions, and economy. It is suitable for high-vibration and multi-pipeline integration scenarios such as automobiles, providing an efficient solution for pipeline fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figure 1-5 As shown, the present invention provides a shock-absorbing pipe clamp for use with mushroom nails, including a pipe clamp shell 1, characterized in that the pipe clamp shell 1 is a mirror-symmetrical structure, and the pipe clamp shell 1 has two symmetrically arranged through holes 5 from top to bottom, each through hole 5 is provided with a pair of shock-absorbing rubber pads 2, a placement groove 4 with a stepped hole structure is provided in the middle of the pipe clamp shell 1, a metal claw 3 is detachably clamped in the placement groove 4, a column hole 6 is provided in the center of the bottom of the pipe clamp shell 1, and the metal claw 3 is coaxial with the column hole 6.

[0025] In the present invention, the mirror-symmetrical pipe clamp shell 1 ensures balanced overall force and better adaptability; the double through holes 5 and the shock-absorbing rubber pad 2 can simultaneously fix and dampen two pipes, expanding the usage scenarios; the stepped hole placement groove 4 accurately positions the metal claw 3, and the column hole 6 is coaxial with the metal claw 3 to ensure alignment with the mushroom nail during assembly, thereby improving connection accuracy and reliability.

[0026] There are two symmetrically arranged protrusions 14 in the middle of the placement groove 4, and the outer wall of the metal claw 3 is provided with four annular grooves 15 evenly distributed, and the two symmetrically distributed grooves 15 and the protrusions 14 are engaged with each other.

[0027] In the present invention, the protrusion 14 is inserted into the groove 15 to limit the rotation of the metal claw 3 in the placement groove 4, ensuring that the metal claw is always aligned with the mushroom nail; the four annular grooves 15 can be flexibly selected to be symmetrical grooves and matched with the protrusions to fine-tune the angle of the metal claw and improve the versatility of installation.

[0028] A buffer block 10 coaxial with the placement slot 4 is provided at the bottom of the placement slot 4 .

[0029] In the present invention, when the metal claw 3 is inserted into the placement groove 4, the bottom contacts the buffer block 10, and the block deforms to buffer the assembly force; when the pipe clamp is in use, the buffer block 10 continuously provides axial buffering to the metal claw 3 to absorb vibration.

[0030] There are symmetrically arranged flip hinge plates 7 in the middle of both sides of the pipe clamp housing 1. The extending end of the flip hinge plate 7 away from the column hole 6 is a hook-shaped hook plate 8. There are two symmetrically arranged card plates 9 at the bottom of the buffer block 10. The hook plates 8 are buckled with the card plates 9, and the clamping direction of the hook plates 8 and the card plates 9 is perpendicular to the axial direction of the column hole 6.

[0031] In the present invention, the flip hinge plate 7 allows the hook plate 8 to be flipped flexibly, which is convenient for the installation / disassembly of the pipe clamp; the hook plate 8 is buckled with the clamping plate 9 to enhance the stability of the pipe clamp shell 1 after closing; the clamping direction is perpendicular to the axial direction of the column hole 6, and the locking force does not affect the axial connection between the pipe clamp and the mushroom nail, thereby ensuring reliability.

[0032] Symmetrically distributed shock-absorbing slots 11 are formed on the inner wall of the through hole 5 , and two symmetrically arranged shock-absorbing blocks 13 are formed on the outer wall of the shock-absorbing rubber pad 2 . The shock-absorbing blocks 13 are snapped into the shock-absorbing slots 11 .

[0033] In the present invention, the shock-absorbing slot 11 cooperates with the shock-absorbing block 13 to axially limit the shock-absorbing rubber pad 2 to prevent it from sliding or shifting in the through hole 5, ensuring that the shock-absorbing rubber pad 2 can stably perform the shock-absorbing and limiting functions; the symmetrical distribution allows the shock-absorbing rubber pad 2 to be evenly stressed, thereby improving the shock-absorbing effect and lifespan.

[0034] The inner side of the shock-absorbing rubber pad 2 is provided with anti-slip strips 12 that are evenly spaced.

[0035] In the present invention, the anti-slip strips 12 increase the friction between the shock-absorbing rubber pad 2 and the pipeline, improving the anti-slip and anti-displacement capabilities of the pipeline in the through hole 5; the uniform spacing allows the friction to be evenly distributed, avoiding excessive local force on the pipeline, and can also disperse vibration energy and enhance the shock absorption effect.

[0036] The pipe clamp housing 1 , the buffer block 10 and the clamping plate 9 are integrally formed.

[0037] In the present invention, one-piece molding reduces the number of parts and assembly links, thereby improving production efficiency; enhancing structural integrity and strength, avoiding stress concentration and structural loosening caused by assembly gaps, and improving the overall reliability and service life of the pipe clamp.

[0038] The working principle of the present invention is:

[0039] 1. Install the shock-absorbing pad 2

[0040] Take a pair of shock-absorbing rubber pads 2, align the shock-absorbing block 13 on the outer wall with the shock-absorbing groove 11 on the inner wall of the through hole 5 of the pipe clamp housing 1, and insert the through hole 5 axially so that the shock-absorbing block 13 is completely inserted into the shock-absorbing groove 11 to complete the installation of a set of shock-absorbing rubber pads; repeat the operation to complete the installation of the shock-absorbing rubber pad 2 in the other through hole 5.

[0041] 2. Metal claw 3 installation

[0042] Take the metal claw 3 and rotate it so that the protrusion 14 in the middle of the placement groove 4 of the pipe clamp housing 1 is aligned with the groove 15 symmetrically distributed on the outer wall of the metal claw 3; insert the metal claw 3 into the placement groove 4, and the protrusion 14 is embedded in the groove 15 to complete the circumferential limitation of the metal claw 3 to prevent rotation; at this time, the bottom of the metal claw 3 contacts the buffer block 10 at the bottom of the placement groove 4, and the elasticity / rigidity of the buffer block 10 is used to achieve preliminary axial support of the metal claw 3.

[0043] 3.Connect pipe clamps with mushroom nails

[0044] Turn over the pre-assembled pipe clamp housing 1 so that the bottom column hole 6 is aligned with the mushroom nail to be installed; press the pipe clamp housing 1 axially so that the metal claws 3 contact and cooperate with the outer wall of the mushroom nail until the pipe clamp housing 1 fits against the installation surface.

[0045] 4. Pipeline installation

[0046] Insert the pipe to be fixed into the through hole 5 of the pipe clamp housing 1; since the through hole 5 is equipped with a shock-absorbing rubber pad 2, the pipe contacts the anti-slip strip 12 on the inner side of the shock-absorbing rubber pad 2, and the anti-slip strip 12 increases the friction force and limits the sliding of the pipe; at the same time, the shock-absorbing rubber pad 2 can absorb the vibration of the pipe and realize the shock-absorbing function.

[0047] 5. Tube clamp housing locking

[0048] If you need to further enhance the stability of the pipe clamp after closing, you can flip the hinge plates 7 on both sides of the pipe clamp housing 1 so that the hook plates 8 at the extended ends of the hinge plates rotate toward the bottom of the buffer block 10; and snap the hook plates 8 into engagement with the card plates 9 at the bottom of the buffer block 10 to complete the additional locking of the pipe clamp housing 1.

[0049] The present invention utilizes the mirror-symmetrical and coaxial design of the pipe clamp housing 1, combined with the anti-slip and shock-absorbing functions of the shock-absorbing rubber pad 2 and the precise clamping of the metal claws 3, to achieve the complete functions of "pipeline fixation + shock-absorbing protection + convenient assembly / maintenance"; the locking structure further enhances the stability in high-vibration scenarios, adapting to the pipeline installation needs of automobiles, machinery and other fields.
