[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 As shown, an adjustable buffer retaining ring support device for fixing a cylindrical pipe includes two semi-circular retaining rings A1 and B2 for covering the pipe. The two semi-circular retaining rings are symmetrically arranged and assembled with a nut 10 and a washer 9. The two semi-circular retaining rings have eight threaded holes evenly distributed around their circumference. High-strength bolts 8 are installed in the threaded holes. The diameter can be adjusted by multiple high-strength bolts 8. The ends of the high-strength bolts 8 are provided with an eighth-circular spiral adjustment structure 3. The eight eighth-circular spiral adjustment structures 3 are sequentially spliced ​​to form a closed structure. The lower part of the semi-circular retaining ring B2 is connected to the base module 12 by a supporting connecting steel plate 11.

[0025] like Figure 3 As shown, a helical compression spring 7 and a buffer damping sleeve 6 are sequentially sleeved on the high-strength bolt 8. The upper and lower ends of the inner wall of the buffer damping sleeve 6 are connected to the two ends of the helical compression spring 7. The buffer damping sleeve 6 is made of silicone buffer material and is used to alleviate the hard contact impact of the high-strength bolt 8 during the tightening process. The helical compression spring 7 is made of steel spring and can provide effective rebound force. The buffer damping sleeve 6 and the helical compression spring 7 are coaxial sleeve-type combinations, which are used to absorb the impact force during the clamping process, compensate for the structural gap, and buffer the running vibration.

[0026] like Figure 3 , Figure 4As shown, the end of the high-strength bolt 8 is connected to the one-eighth disc spiral adjustment structure 3 via a connecting rod 4. A high-friction rubber pad 5 is provided on the inner surface of the spiral adjustment structure 3. This improves the clamping performance and anti-slip capability between the retaining ring assembly and the pipe. The high-friction rubber pad 5 has a high coefficient of friction, which enhances the frictional contact force with the cylindrical pipe 16, reduces slippage caused by vibration, and improves overall stability. The high-friction rubber pad 5 adopts an embedded structure and is fixed to the one-eighth disc spiral adjustment structure 3 by mechanical fastening, possessing good wear resistance and anti-aging properties.

[0027] like Figure 4 As shown, the connection between the two ends of the connecting rod 4 and the high-strength bolts 8 and the one-eighth disc spiral adjustment structure 3 is a shaft connection, which can adaptively adjust the fitting angle and generate deflection during the tightening process.

[0028] like Figure 5 , Figure 6 As shown, the base module 12 is provided with a slide rail type mounting groove 13, and an anti-loosening nut 15 is provided in the slide rail type mounting groove 13. After the supporting connecting steel plate 11 is inserted into the slide rail type mounting groove 13, it is fixed at both ends by the anti-loosening nut 15. An anti-loosening washer 14 is provided at the connection between the anti-loosening nut 15 and the slide rail type mounting groove 13. The position can be adjusted by the anti-loosening nut 15, which is used to maintain the structural tightness under vibration or long-term stress conditions and prevent failure or safety hazards caused by slight movement and loosening.

[0029] The working principle of this utility model is as follows:

[0030] Reference Figure 1 , Figure 2 When the pipe 16 is placed between the two semi-circular retaining rings, rotating the high-strength bolt 8 causes the eight 1 / 8 circular spiral adjustment structures 3 to tighten inward. Each connecting rod 4, due to its axial connection at both ends, can deflect during tightening, allowing the 1 / 8 circular spiral adjustment structure 3 to fit more tightly against the outer wall of the pipe 16. At this time, the high-friction rubber liner 5 provides sufficient friction to fix the pipe 16, the spiral compression spring 7 compresses and absorbs the clamping impact, and the damping sleeve 6 buffers minor vibrations, thus achieving a synergistic effect of reliable structural fixation and vibration protection. After the supporting connecting steel plate 11 is inserted into the slide rail mounting groove 13, it is fixed at both ends by the anti-loosening nut 15, allowing for fine position adjustments in different directions to meet the installation requirements of different layout orientations on site.

[0031] This utility model has a flexible structure and high functional integration, and can be widely used in equipment foundation installation, industrial pipeline system support layout, structural test support devices and other occasions. It is especially suitable for engineering application environments that require frequent changes in pipeline specifications and have high requirements for installation stability.
