Description

Technical Field

[0001] This utility model relates to the field of ball joint structure technology, specifically to a ball joint connector with highly stable rotation. Background Technology

[0002] Ball joints, characterized by highly stable rotation, are widely used connecting components in the mechanical field to achieve flexible rotation and stable connection between parts. A common problem in practical applications is the difficulty in precisely controlling the rotation angle between the ball joint's receiving part and its moving part, which can easily lead to equipment instability due to unrestricted rotation angles during use.

[0003] Comparing the ball joint structure in document CN209800523U, an adjustment cover is used. The curved surface of the opening on the adjustment cover engages with the rotating ball. Loosening the adjustment cover separates the curved surface from the contact surface of the rotating ball, thereby adjusting the ball joint angle. This method achieves adjustment of the ball joint component angle to a certain extent, reduces friction during angle adjustment, and increases service life.

[0004] However, the above-mentioned technical solutions cannot effectively limit multi-angle rotation between ball joint components other than the predetermined direction. When the equipment requires stable rotation in a specific direction to avoid interference from unnecessary rotation in other directions, the structure in the prior art cannot meet the requirements, cannot provide a stable structural foundation for the specific working state of the equipment, and cannot guarantee the accuracy and stability of the equipment operation.

[0005] Therefore, in order to address the shortcomings of the existing technology, a ball joint connector with high stability of rotation was proposed. Utility Model Content

[0008] The locking mechanism is used to restrict the rotation between the movable part of the ball joint and the receiving part of the ball joint;

[0009] The anti-sway mechanism is used to prevent the ball joint bearing part from shaking.

The first connecting rod is symmetrically arranged outside the limiting sleeve. The front end of the first connecting rod is provided with a retaining ring.

[0011] Furthermore, the collar is fixedly connected to the front end of the ball joint receiving part, and the diameter of the contact portion between the collar and the ball joint receiving part is smaller than the diameter of the external portion of the ball joint receiving part.

[0012] Furthermore, the retaining ring and the collar are engaged, the inner side of the limiting sleeve is provided with a reverse thread structure, and the limiting sleeve and the threaded part are threadedly connected.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5 As shown, a ball joint connector with high stability rotation includes: a ball joint receiving part 9, a ball joint moving part 11, a locking mechanism and an anti-sway mechanism. The ball joint moving part 11 is locked from the inside to the outside of the ball joint receiving part 9. A wire 1 is transversely arranged through the middle of the ball joint moving part 11 and the inner side of the ball joint receiving part 9.

[0028] The locking mechanism is used to restrict the rotation between the movable part 11 of the ball joint and the receiving part 9 of the ball joint;

[0029] The anti-sway mechanism is used to prevent the ball joint bearing part 9 from swaying.

[0030] The locking mechanism includes a threaded part 2, a first connecting rod 3, a retaining ring 4, a collar 5, and a limiting sleeve 10. The threaded part 2 is provided at the middle of the outer side of the ball joint movable part 11. The limiting sleeve 10 is provided outside the threaded part 2. The first connecting rod 3 is symmetrically arranged outside the limiting sleeve 10. The retaining ring 4 is provided at the front end of the first connecting rod 3. The collar 5 is provided at the connection between the ball joint receiving part 9 and the ball joint movable part 11.

[0031] The anti-sway mechanism includes a second connecting rod 6, a suction cup 7, a third connecting rod 8, a transverse groove 12, a first sleeve 13, a second sleeve 14, and a sliding rod 15. The second connecting rod 6 is provided at the end of the collar 5 that is away from the ball joint moving part 11. A transverse groove 12 is provided in the middle of the outer side of the ball joint receiving part 9. A sliding rod 15 is provided in the middle of the inner side of the transverse groove 12. A first sleeve 13 is provided at the contact point between the sliding rod 15 and the second connecting rod 6. A second sleeve 14 is sleeved at the other end of the transverse groove 12. A third connecting rod 8 is provided at the top of the second sleeve 14. A suction cup 7 is provided at the end of the third connecting rod 8.

[0032] The remaining applications utilize this ball joint connection, which possesses highly stable rotation, in the mechanical transmission system of a certain precision instrument.

[0033] Precision instruments have extremely high requirements for the relative positional accuracy and stability between components. First, when installing the ball joint structure, according to the design requirements of the instrument, the relative angle between the ball joint receiving part 9 and the ball joint moving part 11 is determined by the positioning mechanism. The limiting sleeve 10 outside the threaded part 2 is rotated. The reverse thread structure inside the limiting sleeve 10 cooperates with the threaded part 2, driving the first connecting rod 3 to rotate. This causes the retaining ring 4 to rotate and enter the collar 5. Since the collar 5 is fixedly connected to the front end of the ball joint receiving part 9 and the diameter of the contact part is smaller than the diameter of the outer part, when the retaining ring 4 is engaged in the collar 5, the ball joint receiving part 9 and the ball joint moving part 11 can only rotate along the axis of the guide wire 1, which meets the specific transmission direction requirements of the instrument and avoids errors caused by unnecessary rotation.

[0034] During instrument operation, the anti-sway mechanism plays a crucial role. The ball joint receiving part 9 needs to be securely installed in a specific position on the instrument. The suction cup 7 contacts the corresponding position on the instrument housing. After the suction cup 7 is adsorbed, it drives the third connecting rod 8 to move. The third connecting rod 8 drives the second sleeve 14 to move outside the slide rod 15 in the transverse groove 12. When the second sleeve 14 abuts against the first sleeve 13, the ball joint receiving part 9 is fixed. The fixed connection relationship between the second sleeve 14 and the third connecting rod 8, the first sleeve 13 and the second connecting rod 6, and the design that the number of the third connecting rod 8 and the second connecting rod 6 are equal, ensure the stability of the installation position of the ball joint receiving part 9, reduce the shaking of the ball joint receiving part 9 caused by the vibration of the instrument operation, ensure the stable operation of the ball joint moving part 11 and the wire 1, effectively guarantee the transmission accuracy and signal transmission stability of the precision instrument, and improve the overall performance of the instrument.

[0035] The remaining parts of the automotive suspension system utilize ball joint connections, which offer high stability during rotation.

[0036] During vehicle operation, the suspension system is subjected to various complex forces and vibrations. When installing the ball joint structure in the suspension system, the locking mechanism is used to adjust the angle between the ball joint receiving part 9 and the ball joint moving part 11. By operating the limiting sleeve 10, its threaded connection with the threaded part 2 drives the first connecting rod 3 and the retaining ring 4 to move, so that the retaining ring 4 engages with the collar 5, restricting the rotation between the ball joint receiving part 9 and the ball joint moving part 11, allowing only rotation along the axis of the guide wire 1. In this way, the relative angle of the ball joint can be fixed according to the specific design of the suspension system and the vehicle driving conditions, ensuring the motion coordination between the components of the suspension system, avoiding abnormal operation of the suspension system due to excessive rotation of the ball joint, and improving the handling and stability of the vehicle.

[0037] For the anti-sway mechanism, when the ball joint receiving part 9 is installed on the car suspension component, the suction cup 7 is attached to the suspension component housing and adsorbed. After the suction cup 7 is under force, the third link 8 drives the second sleeve 14 to move along the slide bar 15 in the transverse groove 12 until it abuts against the first sleeve 13, fixing the position of the ball joint receiving part 9. Since road bumps will cause the suspension system to vibrate during car driving, the anti-sway mechanism effectively reduces the sway of the ball joint receiving part 9, thereby reducing the degree of vibration affecting the ball joint moving part 11 and the wire 1, ensuring the stability of signal transmission or component connection in the suspension system, improving the reliability and durability of the car suspension system, and enhancing the comfort and safety of vehicle driving.

[0038] Working principle: When using the ball joint connection with high stability rotation, the ball joint receiving part 9 is fitted with the ball joint moving part 11 from the inside to the outside. The ball joint moving part 11 and the ball joint receiving part 9 are connected by a wire 1 through the middle of the ball joint moving part 11 and the ball joint receiving part 9. This structural design allows the ball joint receiving part and the ball joint moving part to cooperate with each other, and the wire can realize the corresponding electrical connection or signal transmission function.

[0039] When it is necessary to restrict the rotation between the ball joint movable part 11 and the ball joint receiving part 9, the rotating limiting sleeve 10 is rotated. Due to the threaded connection between the limiting sleeve 10 and the threaded part 2, the limiting sleeve 10 will move along the threaded part 2 when it rotates, and at the same time drive the first connecting rod 3 to rotate. The first connecting rod 3 drives the retaining ring 4 to rotate and move into the collar 5. When the retaining ring 4 is inserted into the collar 5, the free rotation of the ball joint receiving part 9 and the ball joint movable part 11 is restricted in multiple angles, except that they can rotate along the axis of the conductor 1. In this way, the relative angle between the ball joint receiving part and the ball joint movable part can be fixed according to the actual use requirements to avoid unnecessary rotation affecting the normal operation of the equipment.

[0040] When installing the ball joint receiving part 9, the suction cup 7 is brought into contact with and held in place by the corresponding position of the external equipment housing. After the suction cup 7 is subjected to force, it will drive the third connecting rod 8 to move. The third connecting rod 8 will drive the second sleeve 14 to move outside the sliding rod 15 inside the transverse groove 12. When the second sleeve 14 abuts against the first sleeve 13, the first sleeve 13 is fixed to the second connecting rod 6 connected to the collar 5, and the position of the ball joint receiving part 9 is fixed. In this way, the shaking of the ball joint moving part 11 or the wire 1 caused by the shaking of the ball joint receiving part 9 during use is reduced, ensuring the stability of the entire ball joint structure and improving the reliability of equipment operation.

Many modifications and variations will be apparent to those skilled in the art.
