Description

Technical Field

[0001] This utility model relates to the technical field of shock absorber connectors, specifically a universal connector for shock absorber lifting rings. Background Technology

[0002] As a core force transmission component in the vibration reduction system of mechanical equipment, the universal joint of the shock absorber eye is widely used in automotive suspension, vibration reduction devices of construction machinery, rail transit vehicles and industrial automation equipment. Its core function is to realize the flexible connection between the shock absorber and the main body of the equipment at multiple angles, while transmitting the damping force and compensating for installation deviations, so as to ensure the stable operation of the vibration reduction system. Therefore, a kind of universal joint of the shock absorber eye is needed.

[0003] Existing universal joints for vibration damper lifting rings lack protective measures during operation, allowing external dust, mud, rainwater, and other impurities to easily penetrate the interior, leading to accelerated bearing wear. Furthermore, their maximum allowable torsional and deflection angles are relatively small, and their high stiffness makes them prone to transmitting torsional forces to the vibration damper lifting rings, affecting the motion stroke and overall performance of the vibration damping system. Their damping capacity is insufficient, and when faced with large amplitude and high-frequency vibrations, traditional buffer structures struggle to effectively absorb vibration energy, increasing the risk of loose connections or even vibration damper detachment, seriously threatening equipment operational safety. Therefore, a new type of universal joint for vibration damper lifting rings is urgently needed. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a universal joint for a shock absorber lifting ring, in order to solve the problems of existing universal joints for shock absorber lifting rings that lack protective measures during use. External dust, mud, rainwater and other impurities can easily penetrate the interior, leading to accelerated bearing wear. At the same time, their maximum allowable torsional angle and deflection angle are small, and their stiffness is large, which makes it easy to transmit torsional force to the shock absorber lifting ring, affecting the motion stroke and overall performance of the shock absorption system. Their buffering and shock absorption capacity is insufficient. When facing large amplitude and high frequency vibrations, traditional buffer structures are unable to effectively absorb vibration energy, which can easily lead to loose connections or even the shock absorber detaching, seriously threatening the safe operation of equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal connector for a shock absorber lifting ring, comprising a universal connector, a sealing gasket installed on the side wall of the universal connector, a bellows installed on the outer wall of the universal connector, a bolt passing through the inner wall of the bellows, and a nut installed on the outer wall of the bolt.

[0006] The universal connector has a protective sleeve on its side wall, a sleeve rod fixedly connected to the side wall of the universal connector, a telescopic rod installed on the inner wall of the sleeve rod, a buffer spring fixedly connected to the side wall of the universal connector, a connection point provided at one end of the telescopic rod and the buffer spring, a slider provided on the side wall of the connection point, and a groove provided on the inner wall of the sleeve rod.

[0007] Preferably, the sealing gasket is tightly fitted to the side wall of the bellows, and the sealing gasket is bonded to the side wall of the universal connector.

[0008] Preferably, the corrugated pipe is threadedly connected to the universal connector by bolts, and threaded grooves are provided on the side walls at both ends of the corrugated pipe.

[0009] Preferably, the sleeve rod is sleeved with the telescopic rod, and the telescopic rod is sleeved with the buffer spring.

[0010] Preferably, the connection point forms a telescopic structure with the universal connector via a buffer spring, and the connection point is sleeved with the protective sleeve.

[0011] Preferably, the connection is formed by a slider and a protective sleeve to form a sliding structure, and the slider is engaged with the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of sealing gaskets, bellows, bolts and nuts, addresses the issue that traditional universal joints lack effective sealing protection, making the bearings susceptible to corrosion from impurities. This often requires frequent disassembly and cleaning, grease replacement, or even bearing replacement, which not only increases maintenance workload but also raises equipment operating costs. In contrast, this utility model only requires the bellows to be fixed to the universal joint using bolts and nuts, constructing a fully enclosed protective barrier. This effectively prevents various impurities such as road dust, construction mud and sand, rainwater, snowmelt, and corrosive media in the industrial environment from entering the universal bearing. It avoids the grinding action between impurities and bearing balls and raceways, reduces bearing wear and corrosion, ensures that the bearing always maintains good lubrication and rotational flexibility, and guarantees the stable transmission of vibration damping force. 2. This utility model, through the design of a protective sleeve, sleeve rod, telescopic rod, buffer spring, connector, slider, and groove, allows the connector to be stressed when the device is vibrated. The slider moves along the groove into the protective sleeve, causing the telescopic rod to retract into the sleeve rod, compressing the buffer spring. The elasticity of the buffer spring then buffers and releases the vibration force, effectively absorbing vibration energy, reducing the vibration amplitude of the connector and vibration damping system, and improving the operational stability of the equipment. Compared with the rigid connection or simple buffer structure of traditional connectors, this utility model significantly improves buffering efficiency and can better adapt to the vibration requirements under complex working conditions.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] Please see Figures 1-4 A universal joint for a shock absorber lifting ring includes a universal connector 1, a sealing gasket 2 installed on the side wall of the universal connector 1, a bellows 3 installed on the outer wall of the universal connector 1, a bolt 4 passing through the inner wall of the bellows 3, and a nut 5 installed on the outer wall of the bolt 4. The sealing gasket 2 is tightly fitted to the side wall of the bellows 3 and is also bonded to the side wall of the universal connector 1. The bellows 3 is threadedly connected to the universal connector 1 by the bolt 4, and threaded grooves are opened on the side walls at both ends of the bellows 3. When using the device, the sealing gasket 2 is bonded to the side wall of the universal connector 1, and then the bellows 3 is fitted onto the universal connector 1 to completely cover the universal bearing area. Then, the bolt 4 is passed through the mounting hole on the edge of the bellows and the corresponding fixing hole of the universal connector, and then fixed with the nut 5. This can prevent dust, mud, water and other impurities from entering the interior of the universal bearing, reduce wear and extend service life.

[0018] Please see Figures 1-4A universal connector for a shock absorber lifting ring includes a protective sleeve 6 on the side wall of the universal connector 1, a sleeve rod 7 fixedly connected to the side wall of the universal connector 1, a telescopic rod 8 installed on the inner wall of the sleeve rod 7, and a buffer spring 9 fixedly connected to the side wall of the universal connector 1. A connection point 10 is provided at one end of the telescopic rod 8 and the buffer spring 9. A slider 11 is provided on the side wall of the connection point 10. A groove 12 is formed on the inner wall of the sleeve rod 7. The sleeve rod 7 is sleeved with the telescopic rod 8, and the telescopic rod 8 is sleeved with the buffer spring 9. The connection point 10 forms a telescopic structure with the universal connector 1 through the buffer spring 9, and the connection point 10 is sleeved with the protective sleeve 6. The slider 11 and the protective sleeve 6 form a sliding structure, and the slider 11 is engaged with the slide groove 12. When the device is in use, when the device is subjected to vibration, the vibration force is transmitted to the connection 10. The connection 10 is subjected to force and moves into the protective sleeve 6 along the slide groove 12 using the slider 11. At the same time, it drives the telescopic rod 8 to retract into the sleeve rod 7. As the telescopic rod 8 retracts, the buffer spring 9 is gradually compressed. In this process, the kinetic energy of the vibration is converted into the elastic potential energy of the spring, realizing the efficient absorption of vibration energy, effectively weakening the impact of vibration force on the connection head and surrounding structure, thereby improving the stability of the device and preventing the vibration damper from detaching.

[0019] Working principle: In use, first move the device to a suitable position, then adhere the sealing gasket 2 to the side wall of the universal connector 1, then put the bellows 3 onto the universal connector 1, and then use bolts 4 and nuts 5 to fix the bellows 3 onto the universal connector 1. This can prevent dust, mud, water and other impurities from entering the universal bearing, reduce wear and extend service life. Then, use the connection 10 to connect the vibration damper and the installation equipment. In use, when the device is vibrated, the vibration force is transmitted to the connection 10. The connection 10 is stressed and moves along the slide groove 12 into the protective sleeve 6 using the slider 11, which drives the telescopic rod 8 to retract into the sleeve rod 7, and simultaneously compresses the buffer spring 9. The elasticity of the buffer spring 9 is then used to buffer and release the vibration force to improve the stability of the device and prevent the vibration damper from detaching. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
