[0024] like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a universal adjustable suspension tie rod device, including a carbon fiber rod body 4. Both ends of the carbon fiber rod body 4 are sequentially fitted with a carbon fiber rod body fixing wedge sleeve 8, a carbon fiber rod body support frame 7, a first universal ball joint 6, a ball joint connecting frame 5, a second universal ball joint 3, and a ball joint contact frame 10. One side of the carbon fiber rod body support frame 7 is wedge-tightly engaged with the carbon fiber rod body fixing wedge sleeve 8 to clamp and fix the carbon fiber rod body 4. The carbon fiber rod body support frame 7, the first universal ball joint 6, the ball joint connecting frame 5, the second universal ball joint 3, and the ball joint contact frame 10 are sequentially connected by spherical joints. The ball joint contact frame 10 is detachably connected to the fixed support base 1 through a connecting assembly.

[0025] In this embodiment, the carbon fiber rod 4 serves as the support carrier, and the complete set of components arranged symmetrically at both ends ensures bidirectional adjustment consistency. The carbon fiber rod support frame 7, the first universal ball joint 6, the ball joint connecting frame 5, the second universal ball joint 3, and the ball joint contact frame 10 are sequentially connected by spherical joints to form multiple rotatable connection nodes. The synergistic effect of the first universal ball joint 6 and the second universal ball joint 3 breaks the limitation of traditional tie rods that can only be finely adjusted along the axial direction, giving the device a multi-dimensional rotational freedom in space. It can flexibly compensate for the multi-dimensional deviations in the lateral, longitudinal, and angular directions between the installation foundations of the 300K outer cylinder 12 and the 4K outer cylinder 13. At the same time, the ball joint contact frame 10 is detachably connected to the fixed support seat 1 through the connecting component. During assembly, the connecting component can be kept in an unlocked state. The free rotation characteristics of the spherical joint allow the tie rod device to automatically adapt to the relative position of the installation foundation. It does not require high-precision initial alignment or complex manual calibration operations, completely eliminating the strict dependence of existing structures on initial precision, greatly simplifying the adjustment process, and achieving fast and accurate assembly.

[0026] Specifically, the ball pair contact frame 10, the second universal ball pair 3, the ball pair connecting frame 5, the first universal ball pair 6, the carbon fiber rod body support frame 7 and the carbon fiber rod body fixing wedge sleeve 8 are sequentially sleeved on the carbon fiber rod body 4, the direction of the hole of the ball pair connecting frame 5 is perpendicular to the direction of the hole of the ball pair contact frame 10, the carbon fiber rod body fixing wedge sleeve 8 is preliminarily fixed (not locked), at this time, the double universal ball pairs and each spherical pair are in a free state, a space is reserved for subsequent rotation adjustment, the two fixed support seats 1 are respectively welded and fixed to the predetermined positions of the 300K outer cylinder 13 and the 4K outer cylinder 12, and installation bases of two ends of the device are formed. Even if there are multi-dimensional deviations such as lateral deviation and angle inclination between the two base surfaces, the deviations can be compensated through subsequent adjustment, the screw rod parts of the bolt seats 2 at the two ends of the pre-assembled adjustment module pass through the installation holes of the corresponding fixed support seats 1, and the connecting nuts 9 are pre-wrenched but not locked. At this time, since the connecting assembly is not completely fixed, the first universal ball pair 6 and the second universal ball pair 3 can freely rotate under the action of the rolling body 16, each spherical pair can also be flexibly attached and deflected, and the device as a whole is in a flexible adjustment state. The carbon fiber rod body 4 will automatically adjust the spatial posture under the action of gravity and installation deviation, the position deviation and angle deviation between the 300K outer cylinder 12 and the 4K outer cylinder 13 are compensated through the cooperative rotation of the double universal ball pairs, until the device is in stress balance, automatic alignment is realized, and manual calibration is not needed. When the device is automatically aligned to the best position, the connecting nuts 9 at the two ends are first tightened, the displacement of the ball pair contact frame 10 is limited through the locking of the bolt seats 2 and the fixed support seats 1, and then the carbon fiber rod body fixing wedge sleeve 8 is finally fastened, the carbon fiber rod body 4 is clamped and fixed through the taper wedge tight cooperation between the carbon fiber rod body fixing wedge sleeve 8 and the carbon fiber rod body support frame 7. At this time, the rotation degrees of freedom of the double universal ball pairs and each spherical pair are completely locked, the entire device changes from the flexible adjustment state to the rigid support state, stably bears the weight of the coil and resists the shear force in the running process, and the precise adjustment and fixation are completed.

[0027] The carbon fiber rod body fixing wedge sleeve 8 and the carbon fiber rod body support frame 7 realize wedge tightness through the taper surfaces matched with each other.

[0028] As shown in Figure 4 and Figure 5 , the carbon fiber rod body support frame 7 has a first spherical surface, the first universal ball pair 6 has a first inner spherical surface matched with the first spherical surface of the carbon fiber rod body support frame 7 and a first outer spherical surface matched with the ball pair connecting frame 5, the ball pair connecting frame 5 has a second inner spherical surface matched with the first outer spherical surface of the first universal ball pair 6 and a second outer spherical surface matched with the second universal ball pair 3, the second universal ball pair 3 has a third inner spherical surface matched with the second outer spherical surface of the ball pair connecting frame 5 and a third outer spherical surface matched with the ball pair contact frame 10, and the ball pair contact frame 10 has a fourth inner spherical surface matched with the third outer spherical surface of the second universal ball pair 3.

[0029] In this embodiment, the first spherical surface of the carbon fiber rod support frame 7 is in close contact with the first inner spherical surface of the first universal ball pair 6 to form the first rotational node, the first outer spherical surface of the first universal ball pair 6 is adapted to the second inner spherical surface of the ball pair connecting frame 5 to form the second rotational node, the second outer spherical surface of the ball pair connecting frame 5 is matched with the third inner spherical surface of the second universal ball pair 3 to form the third rotational node, and the third outer spherical surface of the second universal ball pair 3 is closely matched with the fourth inner spherical surface of the ball pair contact frame 10 to form the fourth rotational node. The four-stage spherical pair is connected in series to form a continuous and flexible rotational chain; each spherical pair can independently realize a certain angle of pitch and yaw movement, and the inner and outer spherical surfaces of the double universal ball pair are respectively accurately adapted to the spherical surfaces of the adjacent components, further expanding the rotational angle range, so that the device can not only realize fine adjustment along the axis of the carbon fiber rod body 4, but also complete lateral offset compensation and spatial multi-angle inclination adjustment in the X-axis and Y-axis directions, completely breaking the limitation of traditional structure that can only be adjusted in a single dimension. At the same time, compared with the traditional point and line contact, the spherical contact mode significantly increases the contact area between components, improves the shear resistance and load stability of the structure, and the accurate fitting of each spherical surface ensures smooth adjustment without lag, which can adaptively compensate for the multi-dimensional geometric deviation between the 300K outer cylinder 12 and the 4K outer cylinder 13 installation base, without the need for complex manual calibration, which not only reduces the dependence on initial assembly accuracy, but also ensures the accurate positioning and long-term stable support of the coil suspension.

[0030] As shown in Figure 6 and Figure 7 The ball pair connecting frame 5 is provided with a first hole 11 through which the carbon fiber rod body 4 passes, and the ball pair contact frame 10 is provided with a second hole 14 through which the carbon fiber rod body 4 passes, and the direction of the first hole 11 is perpendicular to the direction of the second hole 14.

[0031] In the embodiment, the first hole 11 and the second hole 14 provide smooth channels for the carbon fiber rod body 4 to pass through, ensuring that the rod body movement is not interfered; and the two mutually perpendicular directions are arranged, further expanding the boundary of the rotation freedom degree of the device, the direction of the first hole 11 provides a first in-plane swing space for the carbon fiber rod body 4, and the vertical direction of the second hole 14 provides a swing space in the orthogonal plane, cooperating with the spherical pair connection frame 5 and the spherical pair of the second universal ball pair 3, so that the carbon fiber rod body 4 can not only be adjusted in the axial direction, but also can be flexibly deflected in two perpendicular spatial planes, and combined with the pitching movement of the double universal ball pair, finally forming a complete three-dimensional adjustment capability in space. Breaking the limitation of traditional pull rods that can only be adjusted in one direction, the device can accurately compensate for the multi-dimensional geometric deviations such as lateral offset and angular inclination between the 300K outer cylinder 12 and the 4K outer cylinder 13 installation foundation, and can realize automatic alignment without complex manual calibration, which not only reduces the strict dependence on the initial assembly accuracy, but also ensures the accurate positioning of the coil suspension. At the same time, the vertical hole can avoid interference between the rod body and the hole wall during adjustment, ensuring smooth and stable adjustment.

[0032] As shown in Figure 1 and Figure 8 , the connecting assembly includes a bolt seat 2 and a connecting nut 9 threadedly connected with the bolt seat 2, the bolt seat 2 is connected with the spherical pair contact frame 10, and the threaded part of the bolt seat 2 passes through the mounting hole provided on the fixed support seat 1 and is locked by the connecting nut 9.

[0033] In the embodiment, the bolt seat 2 is fixedly connected with the spherical pair contact frame 10, ensuring that the connecting assembly and the spherical pair contact frame 10 form a stable integrated structure, providing a reliable carrier for subsequent assembly with the fixed support seat 1; the threaded part of the bolt seat 2 passes through the mounting hole on the fixed support seat 1, which not only realizes accurate positioning of the connecting assembly and the fixed support seat 1, but also reserves flexible space for device adjustment. In the early stage of assembly, the connecting nut 9 can be pre-tightened without being locked, so that the spherical pair contact frame 10 drives the double universal ball pair and the carbon fiber rod body 4 to maintain a free adjustment state, and the installation deviation compensation is realized by cooperating with the rotation of the spherical pair and the universal ball pair; after the device is automatically aligned, the connecting nut 9 is tightened, and the bolt seat 2 and the fixed support seat 1 are firmly fixed by the locking force of the threaded connection, so that the device is smoothly switched from a flexible adjustment state to a rigid support state, ensuring the long-term stability of the coil suspension.

[0034] As shown in Figure 9 and Figure 10 , a plurality of mounting holes are provided on the first universal ball pair 6 and the second universal ball pair 3, and a rolling body 16 is arranged in each mounting hole.

[0035] In the embodiment, the plurality of mounting holes on the first universal ball pair 6 and the second universal ball pair 3 provide the rolling body 16 with a precise positioning and uniform distribution mounting space, ensuring that the rolling body 16 is uniformly arranged along the circumferential direction and the radial direction of the spherical surface of the universal ball pair, avoiding stress concentration during adjustment; the rolling body 16 in each mounting hole can roll when the universal ball pair rotates, converting the spherical surface sliding friction between the first universal ball pair 6 and the carbon fiber rod body support frame 7, the ball pair connecting frame 5, and the spherical surface sliding friction between the second universal ball pair 3 and the ball pair connecting frame 5, the ball pair contact frame 10 into rolling friction, greatly reducing the rotation resistance, making the device more smooth and flexible when compensating for the multi-dimensional deviation of the 300K outer cylinder 12 and the 4K outer cylinder 13, avoiding the phenomenon of jamming, and ensuring the efficient and accurate automatic alignment process.

[0036] Specifically, the first universal ball pair 6 and the second universal ball pair 3 are structurally identical, and each includes a retainer 15, and the mounting holes are formed on the retainer 15.

[0037] As shown in Figure 1 and Figure 2 , the carbon fiber rod body 4 is symmetrically provided with two sets of identical fixed support seats 1, connecting assemblies, ball pair contact frames 10, second universal ball pairs 3, ball pair connecting frames 5, first universal ball pairs 6, carbon fiber rod body support frames 7, and carbon fiber rod body fixed wedge sleeves 8 at both ends.

[0038] In the embodiment, the two sets of fixed support seats 1, connecting assemblies, ball pair contact frames 10, double universal ball pairs, ball pair connecting frames 5, carbon fiber rod body support frames 7, and fixed wedge sleeves 8 symmetrically arranged at both ends of the fiber rod body 4 ensure that the adjustment capability and support strength of both ends of the device are completely consistent, making the carbon fiber rod body 4 balanced in stress, avoiding stress concentration or partial load deformation caused by unilateral structural differences, and ensuring that both ends of the device can complete adaptive adjustment synchronously and smoothly when compensating for the multi-dimensional deviation of the 300K outer cylinder 12 and the 4K outer cylinder 13, improving the overall adjustment accuracy and stability.

[0039] The installation method of the universal adjustable suspension pull rod device comprises the following steps: S1: sequentially sleeving a ball pair contact frame 10, a second universal ball pair 3, a ball pair connecting frame 5, a first universal ball pair 6, a carbon fiber rod body support frame 7 and a carbon fiber rod body fixing wedge sleeve 8 on a carbon fiber rod body 4, and making the hole direction of the ball pair connecting frame 5 perpendicular to the hole direction of the ball pair contact frame 10, and preliminarily fixing the carbon fiber rod body fixing wedge sleeve 8; S2: fixing two fixed support seats 1 to predetermined positions of a first external structure and a second external structure respectively; S3: preliminarily connecting the connecting assemblies at both ends of the pre-assembled adjustment module with the corresponding fixed support seats 1 respectively and keeping the non-locked state, and under the rotation compensation of the first universal ball pair 6 and the second universal ball pair 3, the pull rod device automatically adapts and is in a free adjustment state to match the relative positions of the two fixed support seats 1; S4: when the position adjustment is completed, the connecting assemblies at both ends are locked, and the carbon fiber rod body fixing wedge sleeve 8 is finally fastened, so that the whole device changes to a rigid support state.

[0040] In the embodiment, the ball pair contact frame 10, the second universal ball pair 3, the ball pair connecting frame 5, the first universal ball pair 6, the carbon fiber rod body support frame 7 and the carbon fiber rod body fixing wedge sleeve 8 are sequentially sleeved on the carbon fiber rod body 4, and the hole direction of the ball pair connecting frame 5 is perpendicular to the hole direction of the ball pair contact frame 10, so that the integrated pre-assembly of the adjustment module is realized, the cumbersome operation of on-site one-by-one component alignment is avoided, and the installation time is greatly shortened; the two fixed support seats 1 are fixed to predetermined positions of the first external structure and the second external structure respectively, so as to provide a stable installation reference for the device; the connecting assemblies at both ends of the pre-assembly module are preliminarily connected with the fixed support seats 1 and kept in the non-locked state, and by means of the rotation compensation ability of the first universal ball pair 6 and the second universal ball pair 3, the device automatically adapts and matches the relative position deviation of the two fixed support seats 1, without manual calibration, and the strict dependence on the initial assembly precision is completely eliminated; after the position adjustment is in place, the connecting assemblies are locked and the carbon fiber rod body fixing wedge sleeve 8 is fastened, so that the device is smoothly switched from the flexible adjustment state to the rigid support state, which not only guarantees the accurate positioning of the coil suspension, but also ensures the structural stability during long-term operation, and the installation process realizes the three goals of simple assembly, accurate adjustment and reliable locking, and significantly improves the engineering application efficiency of the device.

[0041] Specifically, in step S3, the preliminary connection is realized by penetrating the screw rod part of the bolt seat 2 through the mounting hole of the fixed support seat 1 and pre-wrenching the connecting nut 9 without tightening; in step S3, the alignment process depends on the free rotation of the first universal ball pair 6 and the second universal ball pair 3 in the non-locked state, so that the spatial posture of the carbon fiber rod body 4 automatically adapts and compensates for the relative position and angle deviation between the first external structure and the second external structure.

[0042] The first external structure is a 300K outer cylinder 13, and the second external structure is a 4K outer cylinder 12.

[0043] The above disclosed are only several specific embodiments of the present application, but the embodiments of the present application are not limited to this. Any changes that can be thought of by those skilled in the art shall fall within the protection scope of the present application.

6. The universal adjustable suspension tie rod device as described in claim 1, characterized in that, The carbon fiber rod fixing wedge sleeve (8) and the carbon fiber rod support frame (7) are wedge-tightened through their mutually cooperating conical surfaces.

7. The universal adjustable suspension tie rod device as described in claim 1, characterized in that, The carbon fiber rod (4) is symmetrically provided with two identical fixed support bases (1), connecting components, ball joint contact frames (10), second universal ball joints (3), ball joint connecting frames (5), first universal ball joints (6), carbon fiber rod support frames (7) and carbon fiber rod fixing wedge sleeves (8) at both ends.

8. A method for installing a universal adjustable suspension tie rod device, applied to the device as described in any one of claims 1-7, characterized in that, Includes the following steps: S1: The ball joint contact frame (10), the second universal ball joint (3), the ball joint connecting frame (5), the first universal ball joint (6), the carbon fiber rod support frame (7) and the carbon fiber rod fixing wedge sleeve (8) are sequentially fitted onto the carbon fiber rod (4), and the hole direction of the ball joint connecting frame (5) is kept perpendicular to the hole direction of the ball joint contact frame (10) to initially fix the carbon fiber rod fixing wedge sleeve (8). S2: Fix the two fixed support seats (1) to the predetermined positions of the first external structure and the second external structure respectively; S3: Connect the connecting components at both ends of the pre-assembled adjustment module to the corresponding fixed support base (1) respectively, and keep them in an unlocked state. Under the rotation compensation of the first universal ball joint (6) and the second universal ball joint (3), the pull rod device automatically adapts and is in a free adjustment state to match the relative position of the fixed support base (1) at both ends. S4: After the position is adjusted, lock the connecting components at both ends and finally tighten the carbon fiber rod fixing wedge sleeve (8) to make the whole device become a rigid support state.

9. The installation method as described in claim 8, characterized in that, In step S3, a preliminary connection is achieved by passing the screw portion of the bolt seat (2) through the mounting hole of the fixed support seat (1) and pre-tightening the connecting nut (9) but not tightening it.

10. The installation method as described in claim 8, characterized in that, In step S3, the alignment process relies on the free rotation of the first universal joint (6) and the second universal joint (3) in the unlocked state, so that the spatial posture of the carbon fiber rod (4) automatically adapts to and compensates for the relative position and angle deviation between the first external structure and the second external structure.
