Description

Technical Field

[0001] The utility model relates to a pressing ring, in particular to a pressing ring structure. Background Art

[0002] A pressing ring is a mechanical component used to apply pressure to fix an object or component. It presses an object tightly through a ring structure to prevent loosening or displacement. The main function of the pressing ring is to ensure the firm connection or sealing of components in a system, and it is commonly found in the following application scenarios:

[0003] Ordinary pressing rings are prone to loosening in high-vibration or impact environments. Especially in mechanical equipment, automotive engines or pipeline systems, without additional locking devices, vibration may cause the fixing effect of the pressing ring to decline, affecting safety.

[0004] It should be noted that the above content belongs to the technical cognition scope of the utility model person and does not necessarily constitute the prior art. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a pressing ring structure.

[0006] To achieve the above purpose, the utility model proposes a pressing ring structure, including two connecting rings:

[0007] One end of each of the two connecting rings is communicated with a fixing ring. One end of each of the two fixing rings is respectively communicated with a first inner ring and a second inner ring. The side walls of the first inner ring and the second inner ring are respectively provided with first right-angle sawteeth and second right-angle sawteeth. The first right-angle sawteeth and the second right-angle sawteeth are meshed. The edge positions of the side walls of the two connecting rings are connected through a plurality of buffer structures.

[0008] In one example, the buffer structure includes limiting holes symmetrically and fixedly arranged on the two connecting rings. Through rods are fixedly arranged inside the pairwise symmetrically arranged limiting holes. The two through rods are inserted and connected with a sleeve. One end of each of the two through rods is fixedly provided with a metal cylinder block. One end of each of the two metal cylinder blocks is fixedly provided with a spring. One end of each of the two springs is fixedly connected to both ends of a damping slider. The damping slider is in contact with the inner wall of the sleeve.

[0009] In one example, an arc-shaped inner groove is formed on the outer wall of the damping slider, and a damping ring is sleeved inside the arc-shaped inner groove. The size of the damping ring matches the size of the arc-shaped inner groove.

[0010] In one example, the size of the first right-angle sawteeth matches the size of the second right-angle sawteeth.

[0011] In one example, threaded holes are symmetrically formed on the sides of the two connecting rings, and the positions of the threaded holes are staggered from the positions of the limiting holes.

[0012] The pressing ring structure proposed by the present utility model can bring the following beneficial effects:

[0013] The present utility model has a first inner ring and a second inner ring, and the first right-angled sawteeth and the second right-angled sawteeth provided on the first inner ring and the second inner ring are meshed with each other. The sawtooth structure can provide strong anti-slip performance. Especially when the pressing ring is subjected to large external forces or vibrations, the sawteeth of the two combined pieces bite with each other, increasing the friction force and preventing the pressing ring from loosening. This is particularly important for application scenarios that need to bear high loads or vibrations for a long time. Moreover, the self-locking effect formed by the mutual biting can ensure the fixation of the pressing ring without additional locking devices. This design can effectively avoid loosening phenomena caused by thermal expansion, vibration or external force during long-term use, improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As Figures 1 to 5 shown, an embodiment of the present utility model provides a pressing ring structure, which includes two connecting rings 1:

[0027] One end of each of the two connecting rings 1 is communicatively provided with a fixing ring 14. One end of each of the two fixing rings 14 is communicatively provided with a first inner ring 3 and a second inner ring 4 respectively. A first right-angled sawtooth 5 and a second right-angled sawtooth 15 are respectively arranged on the side walls of the first inner ring 3 and the second inner ring 4. The first right-angled sawtooth 5 and the second right-angled sawtooth 15 are meshed. The edge positions of the side walls of the two connecting rings 1 are connected by a plurality of buffer structures.

[0028] Specifically, the buffer structure includes limiting holes 6 symmetrically and fixedly arranged on the two connecting rings 1. A through rod 8 is fixedly arranged inside each of the two pairs of symmetrically arranged limiting holes 6. The two through rods 8 are inserted and connected with a sleeve 2. One end of each of the two through rods 8 is fixedly provided with a metal cylindrical block 13. One end of each of the two metal cylindrical blocks 13 is fixedly provided with a spring 9. One end of each of the two springs 9 is fixedly connected with both ends of a damping slider 10. The damping slider 10 is in contact with the inner wall of the sleeve 2.

[0029] Specifically, an arc-shaped inner groove 11 is formed on the outer wall of the damping slider 10. A damping ring 12 is sleeved inside the arc-shaped inner groove 11. The size of the damping ring 12 matches the size of the arc-shaped inner groove 11.

[0030] Specifically, the size of the first right-angled sawtooth 5 matches the size of the second right-angled sawtooth 15.

[0031] Specifically, threaded holes 7 are symmetrically formed on the sides of the two connecting rings 1. The positions of the threaded holes 7 are staggered with the positions of the limiting holes 6.

[0032] Working principle: The compression ring is composed of two connecting rings 1, and both ends are connected to the first inner ring 3 and the second inner ring 4 through fixing rings 14. The side walls of the first inner ring 3 and the second inner ring 4 are respectively provided with a first right-angle sawtooth 5 and a second right-angle sawtooth 15. When the right-angle sawteeth of the first inner ring 3 and the second inner ring 4 are engaged, it can effectively increase the friction between the contact surfaces, form a stable self-locking effect, and prevent the compression ring from loosening when subjected to external forces. This structure can provide an efficient locking function and ensure the firmness of the ring. The meshing design of the first right-angle sawtooth 5 and the second right-angle sawtooth 15 enables the compression ring to form a self-locking function in the locked state. This sawtooth meshing not only increases the contact area but also effectively prevents the compression ring from sliding in high-load and vibration environments. Through the close fit of the sawteeth, the radial pressure applied to the first inner ring 3 and the second inner ring 4 can be evenly distributed throughout the entire compression ring structure, ensuring the uniformity of the fastening force. The side wall edges of the two connecting rings 1 are connected through a plurality of buffer structures. The buffer structures include a limit hole 6, a through rod 8, a sleeve 2, a spring 9, and a damping slider 10. When the compression ring is subjected to external impacts or vibrations, the spring 9 will compress or stretch, and by cooperating with the damping slider 10 and the metal cylinder block 13, it absorbs part of the external force, thus playing a role in buffering and shock absorption. This design effectively reduces the loosening and wear of the compression ring caused by vibrations or impacts and extends its service life.

[0033] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.

[0034] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
