[0024] As Figure 1 , 2 , 3, a quick disassembly ball pin connection structure, comprising a spherical shell 1, characterized in that: the outer surface of the spherical shell 1 is respectively provided with x-axis sliding groove 2, y-axis sliding groove 3 and z-axis mounting groove 4 which are communicated with each other; the x-axis sliding groove 2 and the y-axis sliding groove 3 are provided with sliding blocks 5 corresponding to themselves inside; the other side of the sliding block 5 is movably connected with an expansion connecting plate 7 through a movable rotating shaft 6; a pair of transverse rotating plates 8 and a pair of longitudinal rotating plates 9 are uniformly embedded and distributed on the z-axis mounting groove 4 of the spherical shell 1; a pair of limiting rods 10 are connected between the transverse rotating plates 8, and a clamping rod 12 is connected between the limiting rods 10 through a blocking plate 11 and is placed between the longitudinal rotating plates 9; a clamping groove 13 corresponding to the limiting rod 10 is provided on the clamping rod 12. The transverse rotating plate 8 rotates in the y-axis direction, the longitudinal rotating plate 9 rotates in the x-axis direction, and the size of the transverse rotating plate 8 and the longitudinal rotating plate 9 corresponds to the sliding block 5.

[0025] In this embodiment, the spherical shell 1 is the core component of the entire ball pin connection structure, and its surface is designed with interconnected x-axis sliding grooves 2, y-axis sliding grooves 3 and z-axis mounting grooves 4, forming a three-dimensional sliding and mounting system. The x-axis sliding grooves 2 and y-axis sliding grooves 3 are internally configured with corresponding sliding blocks 5, which are connected to the expansion connecting plate 7 through the rotating shaft 6, allowing the expansion connecting plate 7 to rotate and stretch within a certain range. The lateral rotating plate 8 and the longitudinal rotating plate 9 rotate in the y-axis and x-axis directions, respectively, and their sizes match the sliding blocks 5, allowing them to effectively dock with the sliding blocks 5. The lateral rotating plates 8 are connected by limiting rods 10, which are connected to the clamping rods 12 through the blocking plates 11. The clamping grooves 13 on the clamping rods 12 correspond to the limiting rods 10, forming a limiting and clamping system that restricts and cooperates with each other.

[0026] From the implementation points, this component combination realizes the quick disassembly and assembly function of the ball pin connection. During installation, the sliding blocks 5 can slide in the x-axis sliding grooves 2 and y-axis sliding grooves 3, and through the active rotation of the rotating shaft 6, the expansion connecting plate 7 can be connected to the spherical shell 1 from different angles. When disassembly is required, the sliding blocks 5 can be slid into the z-axis mounting grooves 4 from the x-axis or y-axis sliding grooves by rotating the lateral rotating plate 8 and the longitudinal rotating plate 9, achieving quick disconnection. At the same time, the mutual restriction between the limiting rods 10, the blocking plates 11 and the clamping rods 12 ensures that only when the lateral rotating plate 8 and the longitudinal rotating plate 9 are simultaneously rotated and aligned with the z-axis mounting grooves 4 can the disassembly or installation operation be completed, improving the stability and reliability of the connection. In terms of innovation, this structure, through the design of multi-axis sliding grooves and rotating plates, combined with the clever cooperation of limiting and clamping components, greatly simplifies the disassembly and assembly process of the ball pin connection, improves work efficiency, and is especially suitable for mechanical structures or equipment that need to be frequently disassembled and assembled, having significant practical value and promotion prospects.

[0027] As shown in Figure 3 , 4 , 5, the x-axis sliding grooves 2 and y-axis sliding grooves 3 are internally provided with limiting grooves 14 on both sides, and the sliding blocks 5 are integrally connected with T-shaped limiting members 16 corresponding to the limiting grooves 14; the lateral rotating plates 8 and the longitudinal rotating plates 9 are provided with adjusting grooves 17 corresponding to the limiting grooves 14 and the sliding blocks 5. The rotating shaft 6 is connected with the embedded plates 18 having a larger diameter than itself at both ends, and the embedded plates 18 are located inside the sliding blocks 5 and on the side of the expansion connecting plate 7 away from the rotating shaft 6. The limiting rods 10 limit the X-axis direction rotation of the rotating plate 9, and the clamping rods 12 limit the Y-axis direction rotation of the limiting rods 10; the clamping grooves 13 are centrally symmetrically distributed on the clamping rods 12.

[0028] In this embodiment, the spherical shell 1 is used as a core component, and the surface thereof is designed with an x-axis sliding groove 2, a y-axis sliding groove 3, and a z-axis mounting groove 4 that are in communication with each other, forming a three-dimensional sliding and mounting system. The x-axis sliding groove 2 and the y-axis sliding groove 3 are each provided with a limiting groove 14 on both sides, and the sliding block 5 is integrally connected with a T-shaped limiting piece 16 corresponding to the limiting groove 14 on both sides. This T-shaped structure can effectively prevent the sliding block 5 from falling out of the sliding groove 15 during sliding. The transverse rotating plate 8 and the longitudinal rotating plate 9 are provided with an adjusting groove 17 corresponding to the limiting groove 14 and the sliding block 5. The design of the adjusting groove 17 allows the transverse rotating plate 8 and the longitudinal rotating plate 9 to be flexibly adjusted in position and precisely docked with the sliding block 5.

[0029] The rotating shaft 6 is connected with an embedded plate 18 having a larger diameter than the rotating shaft itself at both ends. The embedded plate 18 is located inside the sliding block 5 and on the side of the expansion connecting plate 7 away from the rotating shaft 6. This design not only enhances the connection strength of the rotating shaft 6, but also prevents the expansion connecting plate 7 from shifting or falling off during use through the limiting action of the embedded plate 18.

[0030] The limiting rod 10 is used to limit the rotation of the longitudinal rotating plate 9 in the X-axis direction, and the clamping rod 12 limits the rotation of the limiting rod 10 in the Y-axis direction. The clamping grooves 13 are centrally symmetrically distributed on the clamping rod 12. This symmetric design ensures that the limiting rod 10 can accurately enter the clamping groove 13 when the transverse rotating plate 8 and the longitudinal rotating plate 9 are rotated, achieving stable locking and unlocking functions.

[0031] From the implementation points, this component combination realizes the quick disassembly and assembly function of the ball pin connection. During installation, the sliding block 5 can slide in the x-axis sliding groove 2 and the y-axis sliding groove 3, and through the active rotation of the rotating shaft 6, the expansion connecting plate 7 can be connected with the spherical shell 1 from different angles. When disassembly is required, the sliding block 5 can be slid from the x-axis or y-axis sliding groove into the z-axis mounting groove 4 by rotating the transverse rotating plate 8 and the longitudinal rotating plate 9, achieving quick disengagement. At the same time, the mutual limiting action between the limiting rod 10, the blocking plate 11, and the clamping rod 12 ensures that only when the transverse rotating plate 8 and the longitudinal rotating plate 9 are simultaneously rotated and aligned with the z-axis mounting groove 4, the disassembly or installation operation can be completed, improving the stability and reliability of the connection.

[0032] In specific embodiments, the size of the spherical shell 1 can be adjusted according to the actual application scenario, for example, in small mechanical structures, the spherical shell diameter can be designed to be 50-100 mm; in large equipment, it can be expanded to 200-500 mm. The size of the sliding block 5 should match the sliding groove, and its length and width can be customized according to the size of the sliding groove, usually the length of the sliding block is 1 / 3-1 / 2 of the length of the sliding groove, and the width is consistent with the width of the sliding groove. The limiting piece 16 adopts a T-shaped structure, and its height should be slightly lower than the depth of the sliding groove to ensure that the sliding block 5 can smoothly slide in the sliding groove. The diameter of the rotating shaft 6 can be designed according to the actual stress condition, generally between 10-30 mm, and the diameter of the embedded plate 18 should be 2-3 times larger than the diameter of the rotating shaft to provide sufficient limiting and supporting effect.

[0033] This structure greatly simplifies the disassembly and assembly process of the ball pin connection by designing a multi-axis sliding groove and a rotating plate, and cleverly matching the limiting and clamping components, improves work efficiency, and is especially suitable for mechanical structures or equipment that need to be frequently disassembled, has significant practical value and promotion prospects.

[0034] In use, the sliding block of the product can drive structures in different directions to slide in the corresponding sliding groove, and the rotating shaft rotates, increasing the connection angle range of the ball pin; the core content of the product is that when the sliding block is placed on the horizontal rotating plate or the vertical rotating plate, the sliding direction of the sliding block is changed to the direction of the z-axis mounting groove by rotating the corresponding rotating plate, and the sliding block is slid into the z-axis mounting groove with a larger diameter, that is, the sliding block and the structure connected by the sliding block can be disassembled; it should be noted that the limiting rods, the blocking plate and the clamping rods limit each other, only when the horizontal rotating plate and the vertical rotating plate are rotated at the same time, the blocking plate passes through the gap between the limiting rods, and the limiting rods enter the clamping grooves on the clamping rods, both can be rotated and aligned with the z-axis mounting groove, and disassembly or assembly can be realized.

[0035] Although the present application has been disclosed with reference to the preferred embodiments above, it is not intended to limit the present application, and any person skilled in the art can make various modifications and modifications without departing from the spirit and scope of the present application, therefore the protection scope of the present application should be defined by the claims.
