[0009] 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. Example

[0010] The electronic equipment rack has rotatable and flexibly adjustable joints, see reference. Figures 1 to 3 The system includes a fixed plate 1, a rotating column 2 rotatably connected to the top of the fixed plate 1, an angle adjustment mechanism 3 rotatably connected to the top of the rotating column 2, an angle adjustment mechanism 3 including a support arm 31, a connecting arm 32 rotatably connected to the outside of the support arm 31, and a quick-release splicing mechanism 4 rotatably connected to the left end of the connecting arm 32. The fixed plate 1 provides a stable installation base for the entire equipment frame. Its top is rotatably connected to the rotating column 2, which allows the rotating column 2 to drive the upper structure to rotate flexibly. The angle adjustment mechanism 3 achieves angle adjustment through the rotational cooperation of the support arm 31 and the connecting arm 32. The quick-release splicing mechanism 4 facilitates quick docking or disassembly of clamping components. The overall structure takes into account both flexibility and practicality. Specifically, the fixed plate 1 provides a stable installation base, the rotating column 2 drives the upper structure to rotate horizontally, the support arm 31 and the connecting arm 32 achieve angle adjustment, and the splicing quick-release mechanism 4 installed on the left end of the connecting arm 32 completes the quick docking and disassembly of the clamping components. The overall structure achieves horizontal rotation through the rotating column 2, and the angle adjustment is completed through the rotation of the support arm 31 and the connecting arm 32. The splicing quick-release mechanism 4 provides convenient disassembly and assembly functions, so that the entire equipment frame has multi-directional adjustment capabilities while maintaining stability.

[0011] The support arm 31 is externally fixedly connected to a rotating shaft 33. This fixed connection provides a stable fulcrum for the connecting arm 32, ensuring that the connecting arm 32 can rotate smoothly around the rotating shaft 33. This provides a structural basis for angle adjustment and prevents wobbling or jamming during rotation. The rotating shaft 33 is internally slidably connected to a push post 34. This slidable connection allows the push post 34 to slide flexibly within the rotating shaft 33. Users can trigger subsequent locking or unlocking actions by pressing the push post 34. The operation is convenient and requires no complicated steps. The inner end of the push post 34 is fixedly connected to a fixing component 35. This fixed connection ensures that the sliding of the push post 34 can synchronously drive the fixing component 35 to move, enabling the fixing component 35 to accurately perform the locking or unlocking function and ensuring the fixing effect after angle adjustment. Specifically, a rotating shaft 33 is fixed to the outside of the support arm 31. The rotating shaft 33 provides a fulcrum for the connecting arm 32. A push post 34 is slidably installed inside the rotating shaft 33. The push post 34 can slide back and forth inside the rotating shaft 33. The inner end of the push post 34 is connected to the fixing component 35. When the push post 34 slides, it will move the fixing component 35 together.

[0012] The fixing component 35 includes a connecting plate 351, which is externally fixedly connected to the inner end of the pressing post 34. As an intermediate connecting component of the fixing component 35, the fixed connection between the connecting plate 351 and the inner end of the pressing post 34 can evenly transmit the force of the pressing post 34 to the subsequent components, ensuring that the actions of each part of the fixing component 35 are coordinated. A locking post 352 is externally fixedly connected to the connecting plate 351. The locking post 352 is externally slidably connected to the inside of the connecting arm 32 and the support arm 31. The fixed connection between the external part of the connecting plate 351 and the locking post 352 allows the locking post 352 to slide synchronously with the connecting plate 351. Specifically, the connecting plate 351 is fixed to the inner end of the pressing post 34. The connecting plate 351 drives the locking post 352 to move together. The locking post 352 slides inside the connecting arm 32 and the support arm 31. The connecting plate 351 transmits the force of the pressing post 34 to the locking post 352. The locking post 352 slides inside the support arm 31 and the connecting arm 32 as the connecting plate 351 moves.

[0013] The sliding of the locking post 352 inside the connecting arm 32 and the support arm 31 can lock or unlock both, ensuring stable fixation after angle adjustment. The rear end of the connecting plate 351 is fixedly connected to an anti-deviation ring 353. The outer side of the anti-deviation ring 353 is slidably connected to the inside of the support arm 31. The rear end of the connecting plate 351 is fixedly connected to the anti-deviation ring 353. The sliding of the anti-deviation ring 353 inside the support arm 31 can limit the sliding trajectory of the connecting plate 351, preventing it from deviating and causing the locking post 352 to fail to insert or disengage accurately, thus ensuring the accuracy of the fixed component 35's movement. The inner side of the anti-deviation ring 353 is slidably connected to a push spring 36. The slidable connection between the inner side of the anti-deviation ring 353 and the push spring 36 allows the push spring 36 to extend and retract stably. When the pressing post 34 is pressed, the push spring 36 is compressed and stored. After being released, it rebounds and pushes the connecting plate 351 to reset, causing the locking post 352 to lock automatically, simplifying the operation process. Specifically, the locking pin 352 slides inside the connecting arm 32 and the support arm 31 to lock or unlock them. An anti-deviation ring 353 is fixed at the rear end of the connecting plate 351. The anti-deviation ring 353 slides inside the support arm 31 to prevent the connecting plate 351 from shifting when it moves. A push spring 36 is installed inside the anti-deviation ring 353. When the pressing pin 34 is pressed, the push spring 36 is compressed. When the hand is released, the push spring 36 rebounds, pushing the connecting plate 351 back to its original position and causing the locking pin 352 to lock automatically.

[0014] Reference Figure 1 , Figure 2 and Figure 4 The quick-release mechanism 4 includes a rotating ball 41, which is externally rotatably connected to the left end of the connecting arm 32. The rotatable connection between the external part of the rotating ball 41 and the left end of the connecting arm 32 allows the rotating ball 41 to rotate flexibly within the connecting arm 32, thereby driving the subsequent components to adjust their direction and further improving the flexibility of the equipment frame to adapt to different usage angle requirements. The left end of the rotating ball 41 is fixedly connected to a connecting column 42. The fixed connection between the left end of the rotating ball 41 and the connecting column 42 allows the connecting column 42 to rotate synchronously with the rotating ball 41. At the same time, the connecting column 42 provides an installation base for the subsequent components of the quick-release mechanism 4, ensuring that each component can work together to complete the quick-release and locking functions. Specifically, the rotating ball 41 rotates flexibly inside the left end of the connecting arm 32. This rotating structure allows all components installed on the rotating ball 41 to freely adjust their direction. The connecting column 42 is firmly fixed to the left end of the rotating ball 41. When the rotating ball 41 rotates, it will rotate with the connecting column 42. The connecting column 42 serves as the installation base, and subsequent quick-release structures are installed on this connecting column 42. Through this connection method, the flexibility of the angle adjustment is maintained, while ensuring the stability of the overall structure.

[0015] A limiting post 49 is fixedly connected inside the connecting post 42. The fixed connection between the connecting post 42 and the limiting post 49 provides stable limiting support and prevents the spring from shifting or tilting during the extension and retraction process. A return spring 44 is sleeved on the outside of the limiting post 49. The right end of the return spring 44 is fixedly connected to the push post 45. The fixed connection between the right end of the return spring 44 and the push post 45 allows the elastic force of the return spring 44 to be directly transmitted to the push post 45, driving the push post 45 to accurately return to its original position. This ensures that the push post 45 can reliably press down on subsequent components and achieve the locking function. Specifically, a limiting post 49 is fixedly installed inside the connecting post 42. The main function of the limiting post 49 is to provide a stable support foundation for the entire motion mechanism. A return spring 44 is fitted around the outer ring of the limiting post 49. The right end of the return spring 44 is tightly connected to the push post 45. When the push post 45 is subjected to external force, it will move smoothly along the trajectory of the limiting post 49, while compressing the return spring 44. During this process, the limiting post 49 always maintains the direction of movement of the return spring 44 to prevent it from deviating. When the external pressure disappears, the compressed return spring 44 will immediately release its elasticity and accurately and reliably push the push post 45 back to its original position. This design ensures that the entire mechanism can accurately reset every time.

[0016] The push column 45 is externally fixedly connected to a toggle column 43, which is slidably connected inside the connecting column 42. The fixed connection between the push column 45 and the toggle column 43 allows the user to slide the push column 45 by toggling the toggle column 43. The sliding of the toggle column 43 inside the connecting column 42 restricts its movement trajectory, ensuring precise operation and facilitating locking and unlocking. The connecting column 42 is internally slidably connected to a retaining bead 46, which is externally slidably connected to the connecting column 42. The sliding of the push column 45 inside the connecting column 42 ensures that the push column 45 can only move along the preset direction of the connecting column 42, avoiding deviation that could prevent precise compression of the retaining bead 46 and ensuring the reliability of locking and unlocking actions. The connecting column 42 is externally slidably connected to a retaining ring 48, which allows the retaining ring 48 to flexibly engage or disengage from the connecting column 42, enabling quick assembly or disassembly of the clamping mechanism 47 and the connecting column 42 to meet the needs of different devices. Specifically, the actuating post 43 is fixed outside the pushing post 45. When the actuating post 43 is actuated, it will cause the pushing post 45 to slide inside the connecting post 42. During the sliding process, the pushing post 45 will squeeze or release the retaining bead 46. The retaining bead 46 slides inside the connecting post 42. When the pushing post 45 squeezes the retaining bead 46, the retaining bead 46 will protrude outward. When the pushing post 45 releases the retaining bead 46, the retaining bead 46 can move freely. The retaining ring 48 slides outside the connecting post 42. During installation, the retaining ring 48 is slid onto the connecting post 42. The pushing post 45 will squeeze the retaining bead 46, so that the retaining bead 46 is locked between the retaining ring 48 and the connecting post 42. During disassembly, the actuating post 43 is actuated, and the pushing post 45 releases the retaining bead 46, so that the retaining ring 48 can slide out of the connecting post 42.

[0017] The top of the locking bead 46 is slidably connected to the inside of the retaining ring 48. The inside of the connecting post 42 is slidably connected to the locking bead 46. The sliding of the top of the locking bead 46 inside the retaining ring 48 allows the locking bead 46 to be inserted into the retaining ring 48 under the pressure of the pushing post 45, thus achieving a firm lock between the connecting post 42 and the retaining ring 48 and preventing accidental disengagement during use. The left end of the retaining ring 48 is fixedly connected to the clamping mechanism 47. The fixed connection between the left end of the retaining ring 48 and the clamping mechanism 47 allows the clamping mechanism 47 to quickly dock with the retaining ring 48 and the connecting post 42, ensuring that the clamping mechanism 47 can work stably and reliably clamp the electronic equipment after the splicing is completed. Specifically, the locking bead 46 slides inside the connecting post 42, and its top contacts the inside of the retaining ring 48. When the pushing post 45 squeezes the locking bead 46, the top of the locking bead 46 will be locked into the groove inside the retaining ring 48, achieving a firm lock. The left end of the retaining ring 48 is fixedly installed with the clamping mechanism 47. After the retaining ring 48 and the connecting post 42 are connected, the clamping mechanism 47 can be used normally. This connection method not only ensures the stability of the structure, but also realizes the function of quick assembly and disassembly.

[0018] The clamping mechanism 47 includes a clamping plate 471. The right side of the clamping plate 471 is fixedly connected to the right end of the ferrule 48. As the basic component of the clamping mechanism 47, the clamping plate 471 is fixedly connected to the right end of the ferrule 48 to ensure that the clamping plate 471 can be stably installed on the ferrule 48, providing an installation platform for other clamping components and ensuring the stable execution of the clamping action. The clamping plate 471 has a sliding connection to a limiting piece 472 inside. The sliding connection between the clamping plate 471 and the limiting piece 472 allows the limiting piece 472 to slide flexibly within the clamping plate 471, providing a stable force point and driving the sliding column 474 to move, ensuring uniform clamping force. The rear end of the limiting piece 472 is fixedly connected to the sliding column 474. The fixed connection between the rear end of the limiting piece 472 and the sliding column 474 allows the sliding column 474 to slide synchronously with the limiting piece 472, transmitting the elastic force received by the limiting piece 472 to subsequent components and ensuring the realization of the clamping function. Specifically, the right side of the clamping plate 471 is fixed to the ferrule 48, serving as the mounting platform for the entire clamping mechanism 47. The limiting piece 472 slides inside the clamping plate 471, causing the sliding column 474 at the rear end to move together. The sliding column 474 slides synchronously with the movement of the limiting piece 472, so that the entire clamping mechanism 47 can complete the clamping action in a coordinated manner.

[0019] A compression spring 473 is sleeved on the outside of the sliding column 474. The rear end of the compression spring 473 is slidably connected to the inside of the clamping plate 471. The compression spring 473 sleeved on the outside of the sliding column 474 is compressed and stores force when the subsequent component is pulled. After being released, it rebounds and pushes the limiting plate 472 and the sliding column 474, causing the subsequent component to automatically clamp the device. The sliding of the compression spring 473 inside the clamping plate 471 ensures that its extension and contraction are stable and do not deviate. A gripper 475 is fixedly connected to the rear end of the sliding column 474. The fixed connection between the rear end of the sliding column 474 and the gripper 475 allows the gripper 475 to move synchronously with the sliding column 474. The clamping and release of electronic devices are realized by opening and closing the gripper 475. The operation is simple, the clamping is firm, and it can stably fix mobile phones, tablets and other devices. Specifically, a compression spring 473 is sleeved on the outside of the sliding column 474. The rear end of the compression spring 473 slides inside the clamping plate 471. When the gripper 475 is pulled outward, the compression spring 473 is compressed. After the gripper 475 is released, the compression spring 473 automatically rebounds, pushing the limit plate 472 and the sliding column 474 forward. The gripper 475 moves together with the sliding column 474 to achieve the action of clamping or releasing the equipment. Throughout the process, the compression spring 473 extends and retracts smoothly inside the clamping plate 471 to ensure that the clamping force is uniform and reliable.

[0020] The implementation principle of this application embodiment is as follows: When the user uses it, pressing the pressing column 34 will cause the connecting plate 351 to slide inward, causing the anti-deviation ring 353 to slide together. At the same time, it will squeeze the push spring 36. During the movement, the connecting plate 351 will also cause the locking column 352 to disengage from the interior of the connecting arm 32. The connecting arm 32 and the support arm 31 are rotatably connected together through the rotating shaft 33. When the locking column 352 disengages from the interior of the connecting arm 32, the connecting arm 32 and the support arm 31 can rotate to change the angle. When the user releases the hand, the push spring 36 will rebound and push the connecting plate 351. The connecting plate 351 will cause the locking column 352 to slide outward, pass through the support arm 31, and insert into the interior of the connecting arm 32. At this time, the fixation is completed, so that the angle cannot droop due to gravity after the angle is determined, and the operation is convenient. When the user needs to use the device, pulling the gripper 475 outward causes the sliding post 474 to slide, which in turn causes the limiting plate 472 to slide and compress the compression spring 473. The user places the mobile phone, tablet, or other object to be clamped outside the clamping plate 471. Releasing the gripper 475 causes the compression spring 473 to rebound, pushing the limiting plate 472 to move. The limiting plate 472, through the sliding post 474, drives the gripper 475 to complete the clamping of the device. Then, moving the actuating post 43 to the other end causes the pushing post 45 to compress the reset spring 44. The limiting post 49 provides a limit for the reset spring 44. When the push post 45 moves away from below the retaining bead 46, the retaining bead 46 has room to move. At this time, the retaining bead 46 will not be stuck between the retaining ring 48 and the connecting post 42. The retaining ring 48 can then be disengaged or inserted. When inserted, the actuating post 43 is released, and the return spring 44 will rebound to push the push post 45 and the actuating post 43 back to their original positions. The push post 45 will then press the retaining bead 46 upward again. At this time, the retaining bead 46 will be firmly stuck between the inner groove of the retaining ring 48 and the connecting post 42. The retaining ring 48 will then be unable to disengage from the connecting post 42. As long as the bottom of the equipment is equipped with an interface in the style of retaining ring 48, the equipment docking and support can be completed quickly.
