[0002] Shock absorbers are widely used in many fields such as machinery, vehicles, and construction, and their performance directly affects the stability, comfort, and service life of equipment. Traditional shock absorbers mostly only have a single linear damping function. When faced with complex working conditions, such as lateral forces or steering movements, they often struggle to effectively buffer and adjust, leading to increased equipment vibration and severe wear of components. Therefore, this invention provides a shock absorber that solves the above problems. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a shock absorber that, through the sliding connection of the plug and sleeve and the synergy of multiple elastic bodies, combined with structures such as the steering ball, steering sleeve, and buffer correction mechanism, achieves efficient shock absorption while possessing good steering flexibility, buffer correction capability, dust protection function, and wide applicability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a shock absorber, including an insert and a sleeve, wherein the insert and the sleeve are slidably connected, and an elastic body is connected between the insert and the sleeve.

[0005] The plug-in includes a connector and a connector sleeve.

[0026] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0027] Example 1

[0028] like Figures 1-6 As shown in the figure, in this embodiment, a shock absorber is provided, including a plug and a sleeve 1.

[0029] The insert and sleeve 1 are slidably connected, and an elastic body is connected between the insert and sleeve 1. When the shock absorber is subjected to external force, the insert can slide inside the sleeve 1, and the elastic body deforms to absorb and buffer the external force.

[0030] The connector includes a connecting body 2 and a connecting sleeve 4. A steering ball 9 is located in the middle of the connecting body 2, and a steering sleeve 3 is located in the middle of the connecting sleeve 4, fitting around the steering ball 9. A buffer and correction mechanism is provided between the steering ball 9 and the steering sleeve 3, which provides buffering and correction during steering. The overall structural design allows the shock absorber to achieve basic shock absorption while also providing a degree of steering flexibility through the cooperation of the steering ball 9 and the steering sleeve 3. It also provides a buffering effect when subjected to lateral forces. Hinge ears are installed at the ends of both the connecting body 2 and the sleeve 1. These hinge ears can be used to connect the shock absorber to other components, allowing the shock absorber to rotate flexibly within a certain range after installation, adapting to different installation positions and working angles.

[0031] The sleeve 1 has an annular hole inside, into which the connecting sleeve 4 is inserted. A second elastic body 12 is located inside the annular hole, serving as a buffer and damping agent, while also limiting the range of motion of the connecting sleeve 4 within the annular hole. The second elastic body 12 further enhances the damping performance of the shock absorber and works in conjunction with other elastic bodies.

[0032] Example 2

[0033] like Figures 1-6 As shown, based on Embodiment 1, this embodiment provides a buffer correction mechanism, as detailed below:

[0034] The buffer correction mechanism includes a limiting ring 10 fixed to the outside of the steering ball 9. The steering sleeve 3 has a groove inside that fits the limiting ring 10. First elastic bodies 8 are connected to both the upper and lower sides of the limiting ring 10. The first elastic bodies 8 are engaged within the grooves. When the steering ball 9 rotates relative to the steering sleeve 3 or is subjected to a lateral impact, the first elastic bodies 8 on both sides of the limiting ring 10 are compressed or stretched within the grooves. This elastic deformation buffers the external force, and after the force disappears, the steering ball 9 returns to a relatively stable position, thus achieving a correction effect. The first elastic body 8 enhances the shock absorber's buffering and automatic correction capabilities during steering. The first elastic body 8 is a conical spring. Its conical structure allows the spring's stiffness to gradually increase with the amount of compression, better adapting to different magnitudes of external force and providing a more reasonable buffering force.

[0035] The connecting body 2 also includes a limiting rod 6. The connecting body 2 has an inner hole, and a corrective sleeve 7 connects the inner hole and the limiting rod 6. The corrective sleeve 7 can apply a corrective force to the limiting rod 6. When the limiting rod 6 is displaced by an external force, the corrective sleeve 7 will apply a corrective force. Through its connection with the inner hole and the limiting rod 6, the corrective sleeve 7 uses its own elastic deformation to resist the displacement of the limiting rod 6, allowing the limiting rod 6 to return to its normal position.

[0036] The corrective sleeve 7 comprises multiple interconnected arc-shaped plates. The outer circumference of each arc-shaped plate presses against the limiting rod 6. When subjected to pressure from the limiting rod 6, the arc-shaped plates undergo elastic deformation, with their outer circumferences pressing against the limiting rod 6. The elastic force of the arc-shaped plates applies a corrective force to the limiting rod 6. This structural design allows the corrective sleeve 7 to better adapt to the shape and movement of the limiting rod 6, providing a more uniform and effective corrective force. Furthermore, the connection method of the multiple arc-shaped plates increases the flexibility and adaptability of the corrective sleeve 7.

[0037] Example 3

[0038] like Figures 1-6 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a buffer structure, as detailed below:

[0039] The steering ball 9 is fixed to one end of the connecting sleeve 4. The openings of the connecting sleeve 4 and the steering sleeve 3 have clearance space. The steering ball 9 is fixed to one end of the connecting sleeve 4. The clearance space at the openings of the connecting sleeve 4 and the steering sleeve 3 provides space for the rotation of the steering ball 9, so that the steering ball 9 will not be obstructed when rotating. This ensures that the steering ball 9 can rotate flexibly in the steering sleeve 3 and realize the steering function of the shock absorber.

[0040] A dust cover 5 is fixed to one end of the connecting sleeve 4 near the steering sleeve 3. The dust cover 5 is spherical and attached to the outer wall of the steering sleeve 3, forming a sealed structure to prevent dust, impurities, etc. from entering the gap between the steering sleeve 3 and the connecting sleeve 4, thus avoiding any adverse effects on the fit between the steering ball 9 and the steering sleeve 3. This serves to prevent dust and provide protection, extend the service life of the shock absorber, ensure smooth rotation and good fit between the steering ball 9 and the steering sleeve 3, and thereby maintain the stable performance of the shock absorber.

[0041] The connecting sleeve 4 has an insertion hole inside, and the sleeve 1 has an inner rod 11 that fits the insertion hole inside. The inner rod 11 is inserted into the connecting sleeve 4 and connected to a third elastic body 13. When the shock absorber is subjected to external force, relative movement will occur between the inner rod 11 and the connecting sleeve 4. During this process, the third elastic body 13 undergoes elastic deformation, absorbing and buffering the external force. This adds a buffer element to the shock absorber, and the third elastic body 13 further improves the shock absorption effect, enabling the shock absorber to better cope with external impacts of different sizes and frequencies.

[0042] Working principle:

[0043] When the shock absorber is subjected to external force, the insert can slide inside the sleeve 1. The elastic body connecting the insert and the sleeve 1 deforms, and the external force is absorbed and buffered through the elastic deformation of the elastic body, so as to realize the basic shock absorption function of the shock absorber.

[0044] During the process of being subjected to lateral force, the steering ball 9 in the middle of the connector 2 in the plug-in and the steering sleeve 3 in the middle of the connector 4 cooperate with each other. The buffer and correction mechanism between the steering ball 9 and the steering sleeve 3 plays a role. When the steering ball 9 rotates relative to the steering sleeve 3 or is impacted by a lateral external force, the first elastic body 8 (conical spring) on ​​the upper and lower sides of the limiting ring 10 fixed outside the steering ball 9 is compressed or stretched in the groove inside the steering sleeve 3. The external force is buffered by elastic deformation, and after the force disappears, the elastic restoring force is used to make the steering ball 9 return to a relatively stable position, thus achieving buffering and correction.

[0045] Meanwhile, the annular hole inside the sleeve 1 is provided with a second elastic body 12. The connecting sleeve 4 is inserted into the annular hole. The second elastic body 12 restricts the range of motion of the connecting sleeve 4 within the annular hole and plays a buffering and shock-absorbing role when the connecting sleeve 4 moves. If the limiting rod 6 inside the connecting body 2 is displaced by external force, the correcting sleeve 7 connected to the inner hole will use the elastic deformation of multiple interconnected arc plates to apply a corrective force to the limiting rod 6, so that it returns to its normal position.

[0046] Furthermore, when the shock absorber is subjected to external force, the inner rod 11 inside the sleeve 1 inserts into the connecting sleeve 4, and the third elastic body 13 between the inner rod 11 and the connecting sleeve 4 undergoes elastic deformation, further absorbing and buffering the external force and enhancing the shock absorption effect. The clearance space at the opening of the connecting sleeve 4 and the steering sleeve 3 provides space for the rotation of the steering ball 9, ensuring its flexible rotation; the dust cover 5 prevents dust and impurities from entering and maintains a good fit between the steering ball 9 and the steering sleeve 3.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
