Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and more specifically, to a shock-absorbing tube clamp that fits into a blind hole. Background Technology

[0002] Traditional plastic pipe clamps are connected to the car body by drilling through holes, threaded holes, or welding studs into the sheet metal. However, to simplify processes and improve production efficiency, cast aluminum car bodies are now integrally molded with smooth-walled blind holes (eliminating the tapping process) or tapered smooth pillars (replacing welding studs). Traditional plastic pipe clamps can no longer secure them. Furthermore, traditional shock-absorbing pads require separate molds, molding on two injection molding machines before assembly, or the development of two-color molds for rotary two-color injection molding (which requires two sets of molds).

[0003] Chinese utility model patent CN202510843U discloses a pipe clamp with a shock-absorbing device, comprising an upper clamp and a lower clamp, with a shock-absorbing rubber sleeve engaged between the upper and lower clamps. This utility model's pipe clamp with a shock-absorbing device features a detachable shock-absorbing rubber sleeve between the upper and lower clamps, and the locking force is adjusted by a locking screw. This type of pipe clamp significantly reduces vibration in metal pipes and extends the service life of the pipe clamp.

[0004] However, traditional plastic pipe clamps cannot be fixed to the blind holes or pillars of the cast aluminum body, and the shock-absorbing rubber pads require multiple sets of molds for production, which is a complicated process. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing pipe clamp that works with blind holes, which solves the problems that traditional plastic pipe clamps cannot be fixed to the blind holes or pillars of cast aluminum car bodies, and that the shock-absorbing rubber pads require multiple sets of molds for production.

[0006] This utility model is implemented as follows: a shock-absorbing pipe clamp for use with blind holes includes a pipe clamp housing. The pipe clamp housing has two annular cavities in the middle, and shock-absorbing rubber pads are clamped in the annular cavities. A rod is provided at the center of the bottom of the pipe clamp housing. A snap-fit ​​groove is opened in the middle of the rod. A metal clip is clamped in the snap-fit ​​groove. Inclined clip corners are symmetrically fixed to the top of the metal clip. A clip plate is fixed at the connection between the clip corner and the metal clip. The clip plate is clamped to the bottom of the rod.

[0007] Furthermore, the top of the pipe clamp housing extends through a hinge and has a cover plate. A positioning protrusion extends from the middle of the cover plate and is placed on one side of the annular cavity. A support sidewall is fixed to the end of the cover plate away from the hinge. A bottom base is fixed to the bottom of the pipe clamp housing near the support sidewall. The bottom end of the support sidewall is fastened to the top of the bottom base.

[0008] Furthermore, the pipe clamp housing has a connecting bridge in the middle, and the top of the connecting bridge has symmetrical hooks, and the positioning protrusion engages with the hooks.

[0009] Furthermore, the inner wall of the annular cavity is provided with four symmetrical through slots, and the outer wall of the shock-absorbing rubber pad is fixed with multiple locking posts, which are engaged in the through slots.

[0010] Furthermore, multiple circumferentially distributed buffer strips are fixed to the inner side of the shock-absorbing rubber pad.

[0011] Furthermore, a limiting ring plate is fixedly connected to the middle of the insertion rod, and the limiting ring plate is placed on top of the snap-fit ​​groove.

[0012] Furthermore, the pipe clamp housing is a one-piece molded structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Blind hole compatibility: By using the angled metal clips to embed into the inner wall of the blind hole, the problem of fixing the blind holes in the smooth wall of the cast aluminum body is solved, eliminating the need for tapping or welding studs and simplifying the body manufacturing process.

[0015] Optimized vibration damping performance: The vibration damping pad and pipe clamp housing are integrally molded in two colors, combined with circumferential buffer strips to achieve multi-directional vibration absorption and reduce pipeline vibration noise;

[0016] Structural reliability: The anti-dislodgement design of the metal clips (clamping plate, limiting ring plate) and the double clamping structure of the cover plate and the housing ensure long-term stable operation in vibration environment;

[0017] Improved production efficiency: One-piece molding process and two-color injection molding reduce the number of molds required (only one set of molds is needed), reduce production costs, and are suitable for mass production;

[0018] Ease of installation: The angled design allows for knob removal, and the snap-fit ​​cover facilitates quick pipe installation, improving assembly efficiency. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figure 1-5 As shown, this utility model provides a shock-absorbing pipe clamp for use with blind holes, including a pipe clamp housing 1. The pipe clamp housing 1 has two annular cavities 11 in the middle. A shock-absorbing rubber pad 2 is clamped in the annular cavity 11. A rod 4 is provided at the center of the bottom of the pipe clamp housing 1. A snap-fit ​​groove 6 is opened in the middle of the rod 4. A metal clip 3 is clamped in the snap-fit ​​groove 6. An inclined snap-fit ​​angle 16 is symmetrically fixed to the top of the metal clip 3. A snap-fit ​​plate 17 is fixed at the connection between the snap-fit ​​angle 16 and the metal clip 3. The snap-fit ​​plate 17 is clamped to the bottom of the rod 4.

[0029] In this invention, the snap-fit ​​design of the annular cavity 11 and the shock-absorbing pad 2 reduces noise by using the elasticity of the shock-absorbing pad to buffer the vibration of the pipeline. The metal clip 3 replaces the traditional plastic clip, utilizing the rigidity and elasticity of the metal. Its inclined clip angle 16 can be embedded in the inner wall of the blind hole, solving the problem of fixing the blind hole in the cast aluminum body. The clip plate 17 snaps onto the bottom of the insertion rod 4 to prevent the metal clip from falling off. At the same time, when subjected to reverse force, the clip angle is embedded deeper, improving the reliability of the fixation.

[0030] The top of the pipe clamp housing 1 extends through the hinge ring 18 to form a cover plate 19. A positioning protrusion 8 extends from the middle of the cover plate 19 and is placed on one side of the annular cavity 11. A support side wall 9 is fixedly connected to the end of the cover plate 19 away from the hinge ring 18. A bottom base 10 is fixedly connected to the bottom of the pipe clamp housing 1 near the support side wall 9. The bottom end of the support side wall 9 is fastened to the top of the bottom base 10.

[0031] In this utility model, the cover plate 19 is connected to the pipe clamp housing through the hinge ring 18, which facilitates the fastening and fixing after the pipe is inserted, improving the convenience of installation; the positioning protrusion 8 cooperates with the annular cavity to limit the displacement of the pipe; the fastening structure between the supporting side wall 9 and the bottom base 10 enhances the stability of the cover plate after it is closed and prevents it from loosening.

[0032] The pipe clamp housing 1 has a connecting bridge 7 in the middle, and the top of the connecting bridge 7 has symmetrical hooks, and the positioning protrusion 8 is engaged with the hooks.

[0033] In this invention, the hook of the connecting bridge 7 engages with the positioning protrusion 8 to form a double locking structure, ensuring that the cover plate is not easily detached after being fastened, thereby improving the overall structure's vibration resistance.

[0034] The inner wall of the annular cavity 11 has four symmetrical through slots 13, and the outer wall of the shock-absorbing rubber pad 2 is fixed with multiple locking posts 14, which are locked in the through slots 13.

[0035] In this invention, the through groove 13 of the annular cavity 11 cooperates with the locking post 14 of the shock-absorbing pad 2 to prevent the shock-absorbing pad from rotating or falling off inside the pipe clamp housing, thus ensuring the continuity and stability of the shock absorption function.

[0036] Multiple circumferentially distributed buffer strips 15 are fixed to the inner side of the shock-absorbing rubber pad 2.

[0037] In this invention, the buffer strip 15 on the inner side of the shock-absorbing pad is distributed circumferentially, which can evenly absorb vibrations in all directions of the pipeline, improve the shock absorption efficiency, and protect the pipeline from high-frequency vibration damage.

[0038] A limiting ring plate 5 is fixedly connected to the middle of the insertion rod 4, and the limiting ring plate 5 is placed on top of the snap-fit ​​groove 6.

[0039] In this invention, the limiting ring plate 5 is placed at the top of the snap-fit ​​groove 6 to limit the axial displacement of the metal clip 3, prevent the clip from popping out or falling off excessively, and further enhance the reliability of the snap-fit ​​structure.

[0040] The pipe clamp housing 1 is a one-piece molded structure.

[0041] In this utility model, the pipe clamp housing 1 adopts an integral molding structure, which reduces assembly processes, improves structural strength, avoids weak points caused by splicing, and reduces production costs.
