The traditional hard disk installation method mostly uses screws for fixation.

In addition, during the process of frequent plugging and unplugging of the hard disk, it is difficult for the traditional device to ensure the stability and reliability of the hard disk connection, which may lead to data transmission failures or hard disk damage.

[0040] See Figures 1 to 12 As shown, the present invention provides an embodiment of a hard disk plugging device, including: a hard disk frame 1 and a handle mechanism 2; the hard disk frame 1 is used for installing a hard disk 3; the handle mechanism 2 includes a fixing plate 21, a rotating arm 22 and a handle 23; the hard disk frame 1 is slidably connected to the fixing plate 21; one end of the rotating arm 22 is rotatably connected to the fixing plate 21, and the other end is rotatably connected to the handle 23; the handle 23 is also rotatably connected to the hard disk frame 1;

[0041] When the handle 23 is rotated, the handle 23 drives the rotating arm 22 to rotate, so that the hard disk frame 1 slides along the fixing plate 21.

[0042] Specifically, the core components of the hard disk plugging and unplugging device in this embodiment include a hard disk frame 1 and a handle mechanism 2. The hard disk frame 1 serves as the exclusive carrier for installing the hard disk 3 and can create a stable installation space for the hard disk 3. The handle mechanism 2 consists of a fixing plate 21, a rotating arm 22, and a handle 23 and is the key component for realizing the plugging and unplugging operations of the hard disk 3. The fixing plate 21 acts as a fixed support structure and takes the rotation of the handle 23 as the power input source. When the user rotates the handle 23, the handle 23 drives the rotating arm 22 to rotate around the connection point with the fixing plate 21. Since the fixing plate 21 remains fixed, the rotation of the rotating arm 22 causes the hard disk frame 1 to slide linearly along the fixing plate 21 through link transmission, thereby realizing the plugging and unplugging actions of the hard disk 3. This design ingeniously converts a simple rotational operation into a linear motion of the hard disk 3 and realizes complex functions using basic mechanical structures. Since the hard disk 3 is installed in the hard disk frame 1, the hard disk 3 also moves along with the sliding of the hard disk frame 1, thus smoothly completing the plugging and unplugging operations. During this process, the rotation angle of the handle 23, the length of the rotating arm 22, and the connection method between the hard disk frame 1 and the fixing plate 21 jointly determine the sliding distance and speed of the hard disk frame 1, ensuring the accuracy and controllability of the operation.

[0043] This design greatly simplifies the plugging and unplugging process of the hard disk 3. Users can easily complete the installation and disassembly operations without the need for additional tools, significantly improving work efficiency. At the same time, the reasonable mechanical structure ensures the stability of the hard disk 3 during the plugging and unplugging process, reduces the risk of damage to the hard disk 3 interface caused by improper operation, effectively improves the reliability of the device, and reduces the maintenance cost and the probability of device damage.

[0044] See Figures 1 to 6 and Figure 8 As shown, in a specific embodiment, the hard disk frame 1 is provided with limit plates 11 on both sides of the fixing plate 21, and the handle 23 is rotatably connected to the limit plates 11.

[0045] Specifically, the setting of the limiting plate 11 is mainly based on the principle of restricting the position of the hard disk frame 1. On the one hand, it can limit the sliding of the hard disk frame 1 along the fixed plate 21, preventing the hard disk frame 1 from deviating from the predetermined track during the sliding process, thus ensuring the accuracy of the plugging and unplugging operation of the hard disk 3. On the other hand, the limiting plate 11 provides a stable rotation connection point for the handle 23, ensuring the stability of the handle 23 during rotation, making the operation of the whole mechanism more reliable, and reducing the risk of operation errors and equipment damage caused by shaking or deviation. When the user rotates the handle 23, the handle 23 rotates around the rotation connection point on the limiting plate 11, and at the same time drives the rotating arm 22 to move. Since the fixed plate 21 is stationary, the rotation of the rotating arm 22 causes the hard disk frame 1 to slide along the fixed plate 21 within the range restricted by the limiting plate 11. During this process, the limiting plate 11 and the fixed plate 21 jointly restrict the movement of the hard disk frame 1, effectively preventing the hard disk frame 1 from shaking or deviating, and ensuring that the hard disk 3 can be plugged and unplugged along an accurate path. This design significantly improves the structural stability and operation reliability of the hard disk plugging and unplugging device. Through the limiting effect of the limiting plate 11, the shaking and deviation of the hard disk frame 1 during sliding are effectively avoided, ensuring the accuracy of the plugging and unplugging of the hard disk 3, further reducing the possibility of damage to the hard disk 3, improving the stability and service life of the equipment, and reducing the frequency of equipment maintenance and replacement.

[0046] See Figures 7 to 8 As shown, in a specific embodiment, the fixed plate 21 is provided with an elastic portion 211, and the elastic portion 211 is provided with a convex point 212; the hard disk frame 1 is provided with a first positioning hole 12 and a second positioning hole 13 along the length direction of the limiting plate 11; when the handle mechanism 2 is in the closed state, the convex point 212 extends into the first positioning hole 12; when the handle mechanism 2 is in the open state, the convex point 212 extends into the second positioning hole 13.

[0047] Specifically, in this embodiment, the positioning and locking of the hard disk frame 1 in different states are realized by means of the elastic force of the elastic part 211 and the cooperation between the bump 212 and the positioning hole. When the hard disk frame 1 is in the closed state, the bump 212 of the elastic part 211 is snapped into the first positioning hole 12 under the action of the elastic force, locking the hard disk frame 1 in the closed state to ensure the stability of the installation of the hard disk 3; when the hard disk 3 needs to be removed, rotate the handle 23 to make the hard disk frame 1 in the open state, and the bump 212 disengages from the first positioning hole 12 and is snapped into the second positioning hole 13, locking the hard disk frame 1 in the open state for easy removal of the hard disk 3. This design uses elastic force to achieve automatic positioning and locking, without complex operations and additional tools, and is simple and reliable to operate. When the user rotates the handle 23 to drive the movement of the rotating arm 22, the hard disk frame 1 will slide along the fixed plate 21. During the sliding process, as the position of the hard disk frame 1 changes, the bump 212 cooperates with different positioning holes. When the hard disk frame 1 slides to the closed position, the bump 212 is snapped into the first positioning hole 12 under the action of the elastic force, keeping the hard disk frame 1 in a stable closed state; when the hard disk frame 1 needs to be opened, the user continues to rotate the handle 23 to overcome the elastic force and make the bump 212 disengage from the first positioning hole 12. As the hard disk frame 1 slides further, the bump 212 will be snapped into the second positioning hole 13 to lock the hard disk frame 1 in the open state. This design enhances the reliability and safety of the hard disk plugging and unplugging device. Through the cooperation between the elastic part 211 and the positioning hole, the automatic positioning and locking of the hard disk frame 1 are realized, effectively avoiding the situation that the hard disk 3 loosens or falls off due to accidental collisions during use, while ensuring the stability during the removal process of the hard disk 3, improving the safety and reliability of the device, and reducing the risk of data loss and device damage.

[0048] In a specific embodiment, the bump 212 is hemispherical or conical.

[0049] Specifically, in the hard disk plugging and unplugging device, the bump 212 is designed to be hemispherical or conical, and its core design principle is based on the optimization effect of geometric shapes on mechanical connection and movement. The hemispherical or conical shape has a unique curved surface structure. This shape makes the contact area between the bump 212 and the positioning hole more uniform compared to sharp or angular shapes, which can effectively reduce the local stress concentration between the bump 212 and the positioning hole, reduce wear, and extend the service life of the components. From the perspective of kinematics, the hemispherical or conical bump 212 can provide a smoother guiding effect during the process of inserting and disengaging from the positioning hole, reduce the movement resistance, make the hard disk frame 1 more fluent when switching between different states, and avoid affecting the operation experience or causing structural damage due to jamming. In addition, the symmetrical structure of the hemispherical or conical shape ensures that the bump 212 is evenly stressed in all directions and can be more stably snapped into the positioning hole under the push of the elastic part 211, ensuring the reliable positioning of the hard disk frame 1 in the closed or open state and enhancing the stability and reliability of the entire hard disk plugging and unplugging device.

[0050] See Figures 4 to 7 and Figure 10 As shown, in a specific embodiment, the fixing plate 21 is further connected with a fixator 24; one end of the handle 23 far from the hard disk frame 1 is detachably connected to the fixator 24.

[0051] Specifically, in this embodiment, the handle 23 is constrained and fixed by the fixator 24, and the connection and separation between the handle 23 and the fixator 24 are realized by a detachable connection method. When the handle mechanism 2 is in the closed state, the handle 23 is connected to the fixator 24, and the fixator 24 plays a fixing role on the handle 23 to prevent the handle 23 from accidentally rotating and ensure the stability of the installation state of the hard disk 3; when it is necessary to disassemble the handle 23 for maintenance or replacement, the handle 23 can be easily disassembled from the fixator 24. Since the fixing plate 21 is fixed, the fixator 24 also remains fixed, so that the handle 23 can be stably constrained and the normal operation of the whole device is ensured.

[0052] When the handle mechanism 2 is in the closed state, the handle 23 is in a connected state with the fixator 24, and the fixator 24 restricts the rotation of the handle 23 through its own structural design to ensure that the hard disk 3 will not be loosened or displaced due to the accidental rotation of the handle 23 in the installed state. When the hard disk 3 is taken out, the user can disengage the handle 23 from the fixator 24, so that the handle 23 enters a rotatable state, which is convenient for operating the handle 23. This design improves the overall stability of the hard disk plugging and unplugging device. Through the fixing effect of the fixator 24, the stability of the handle mechanism 2 during the working process is enhanced, the risk of the hard disk 3 loosening caused by the accidental rotation of the handle 23 is reduced, and the safety of the device operation is guaranteed.

[0053] In a specific embodiment, the fixator 24 includes a base 241, a first elastic member 242 and a sliding member 243; the base 241 is installed on the fixing plate 21; the first elastic member 242 is located in the base 241 and abuts against the sliding member 243; the sliding member 243 is slidably connected to the base 241; when the first elastic member 242 and the sliding member 243 are in the initial state and the handle mechanism 2 is in the closed state, a receiving groove 244 is formed between the sliding member 243 and the base 241, and a part of the handle 23 extends into the receiving groove 244.

[0054] Specifically, in this embodiment, the elastic force of the first elastic member 242 is utilized to push the sliding member 243, and the fixing of the handle 23 is achieved through the cooperation between the sliding member 243 and the handle 23. When the handle mechanism 2 is in the closed state, the first elastic member 242 keeps the sliding member 243 in the initial state, forming a receiving groove 244 between the sliding member 243 and the base 241, and a part of the handle 23 is located in the receiving groove 244, thereby realizing the fixing of the handle 23; when it is necessary to rotate the handle 23, the elastic force of the first elastic member 242 is overcome to push the sliding member 243, so that the handle 23 is no longer restricted by the sliding member 243 and can rotate freely. This design further improves the reliability of the fixing of the handle 23 and the convenience of operation. Through the cooperation between the first elastic member 242 and the sliding member 243, the handle 23 can be connected to or disengaged from the fixator 24 without additional tools or complex operation steps, and the operation is simple and convenient. At the same time, the stability of the handle 23 during the working process is ensured, the accidental rotation of the handle 23 is prevented, the reliability of the device is improved, and the risk of device failure caused by the loosening of the handle 23 is reduced.

[0055] In a specific embodiment, the first elastic member 242 is a V-shaped elastic sheet, one side of the V-shaped elastic sheet is connected to the sliding member 243, and the end of the other side abuts against the inner surface of the base 241.

[0056] Specifically, the unique V-shaped structure of the V-shaped elastic sheet endows it with good elastic performance and mechanical properties. When the sliding member 243 moves under the operation of the handle mechanism 2, the V-shaped elastic sheet is stressed and undergoes elastic deformation. Due to its special shape, a stable and adjustable elastic force can be generated during the deformation process. During the closing process of the handle mechanism 2, the V-shaped elastic sheet is gradually compressed, continuously providing a stable resistance to the sliding member 243, ensuring the smooth movement of the sliding member 243, so that the fixing part 231 of the handle 23 can smoothly enter the predetermined position between the sliding member 243 and the base 241. When the handle mechanism 2 is completely closed, the V-shaped elastic sheet maintains a certain compressed state, continuously applying an elastic force, tightly pressing the sliding member 243 against the fixing part 231 to form a firm clamping, preventing the handle 23 from loosening accidentally, and ensuring the stability of the hard disk plugging and unplugging device during operation. When opening the handle mechanism 2, the elastic force of the V-shaped elastic sheet can assist the sliding member 243 to reset, so that it quickly returns to the initial position to prepare for the next operation. This stable elastic force output and precise control effectively improve the smoothness and reliability of the device operation. It can be understood that in other embodiments, the first elastic member 242 can also adopt an elastic member structure such as a spring.

[0057] In a specific embodiment, the first elastic member 242 and the sliding member 243 are of an integrally formed structure.

[0058] Specifically, the design principle of the integrally formed structure is based on the requirements of simplifying the structure, improving reliability, and optimizing performance. In the traditional separate structure of the first elastic member 242 and the sliding member 243, additional connection methods (such as welding, bolt connection, etc.) are required to combine the two, which may have potential problems such as insufficient strength at the connection part and assembly errors. The integrally formed structure adopts an integrated design and utilizes the characteristics of the material to make the first elastic member 242 and the sliding member 243 an inseparable whole during the manufacturing process. From the perspective of material mechanics, the integrally formed structure avoids the risk of structural failure caused by gaps or stress concentration at the connection part, enabling the elastic force generated by the elastic member to be transmitted to the sliding member 243 more directly and efficiently, achieving stable clamping and release of the handle 23. At the same time, the integrally formed structure reduces the number of components and assembly processes, reduces the possibility of failures caused by improper assembly, and improves the performance and stability of the entire retainer 24 from the structural root cause.

[0059] See Figure 5 , Figure 7 and Figures 9 to 10 As shown, in a specific embodiment, a fixing portion 231 is provided at one end of the handle 23 close to the retainer 24. A guiding surface 232 is formed on one side of the fixing portion 231 facing the fixing plate 21, and the guiding surface 232 is an inclined surface or an arc surface. When the handle 23 rotates until the guiding surface 232 of the fixing portion 231 contacts the sliding member 243, the fixing portion 231 pushes the sliding member 243 to move away from one end of the handle 23. When the handle mechanism 2 is completely closed, the guiding surface 232 no longer contacts the sliding member 243, the sliding member 243 resets, and the fixing portion 231 enters the receiving groove 244 between the sliding member 243 and the base 241.

[0060] Specifically, the design principle of this structure integrates the concepts of mechanical transmission and mechanical optimization. The purpose of setting the fixing portion 231 is to achieve reliable fixation of the handle 23 in a closed state through cooperation with the sliding member 243 and the base 241, prevent it from accidentally rotating, and ensure the stable operation of the hard disk plug-in device. Designing the guide surface 232 as an inclined surface or an arc surface is to utilize the special geometric shape of the curved surface to achieve effective promotion and guidance of the sliding member 243. When the handle 23 rotates and the guide surface 232 of the fixing portion 231 contacts the sliding member 243, the force generated by the contact between the inclined surface or the arc surface and the sliding member 243 can be decomposed into a component force along the sliding direction, thereby pushing the sliding member 243 to move, so as to facilitate the subsequent entry of the fixing portion 231 into the receiving groove 244. From a mechanical point of view, this design can reasonably utilize the contact force and avoid excessive impact due to direct collision. When the handle mechanism 2 is completely closed, the fixed portion 231 no longer abuts against the sliding member 243. At this time, the sliding member 243 is reset under the action of the first elastic member 242, and the fixed portion 231 is clamped in the receiving groove 244 to achieve a tight connection. The design of the inclined surface or arc surface can also play a guiding role in the clamping process, reduce the jamming phenomenon caused by assembly error or operation deviation, ensure smooth completion of the clamping action, and make the stress distribution of the fixed portion 231 more uniform when subjected to force, thereby enhancing the overall strength and reliability of the structure.

[0061] See also Figure 5 and Figure 7 As shown, in a specific embodiment, the handle 23 is also connected to a second elastic member 25; when the end of the handle 23 away from the hard disk frame 1 is detachably connected to the fixer 24, the end of the second elastic member 25 away from the handle 23 abuts against the fixing plate 21, and the second elastic member 25 is in a compressed state.

[0062] Specifically, the design principle of the second elastic member 25 in this embodiment is based on the concept of energy storage and release and mechanical motion assistance. When the fixer 24 stabilizes the handle 23 on the fixed plate 21, the second elastic member 25 is elastically deformed due to the squeezing of the handle 23 and the fixed plate 21, thereby storing elastic potential energy. When the sliding member 243 slides to the fixed portion 231 and is no longer blocked by the sliding member 243, the elastic potential energy stored in the second elastic member 25 is converted into kinetic energy, and the elastic force generated in a specific mechanical action mode pushes the handle 23 to rotate around the connection point with the limit plate 11, so that a preset basic angle is formed between the handle 23 and the fixed plate 21, so that the fixed portion 231 automatically detaches from the receiving groove 244, so as to facilitate the user's grip, reduce the user's operating difficulty, and optimize the operating experience. From the perspective of mechanical structure, the second elastic member 25 plays a key role in energy conversion and motion assistance. Without adding a complex power system, it realizes effective control and assistance of the movement of the handle 23, and improves the convenience and humanization of the hard disk plug-in device.

[0063] More specifically, the second elastic member 25 is a shrapnel. The shrapnel has the characteristics of being thin, light, and having a flexible shape design, and can well adapt to the limited space layout inside the hard disk plugging device. Its flat structure can be cleverly installed in the narrow gap between the handle 23 and the fixing plate 21, without occupying too much internal space of the device, which helps to realize the miniaturization and compact design of the device. At the same time, the shape of the shrapnel can be customized according to the actual installation requirements, so that it can fully play its elastic role in the limited space, and closely cooperate with other components without affecting the stability and compactness of the overall structure of the device. At the same time, during the elastic deformation process of the shrapnel, a relatively stable and moderate elastic force can be generated. When the handle 23 is separated from the fixing plate 21, the elastic force released by the shrapnel can push the handle 23 out with an appropriate force, neither causing the handle 23 to pop out at an insufficient angle due to too small an elastic force, which affects the user's grasping, nor causing the handle 23 to pop out too violently due to too large an elastic force, resulting in safety hazards or damage to surrounding components. This stable and moderate elastic force characteristic enables the user to obtain a smooth and comfortable experience when operating the handle 23, further improving the usability of the device.

[0064] See Figure 4 and Figures 7 to 8 As shown, in a specific embodiment, a limiting portion 14 is connected to the side of the limiting plate 11 close to the fixing plate 21; both the limiting plate 11 and the limiting portion 14 are slidably connected to the fixing plate 21, and the fixing plate 21 is provided with an avoidance groove 213 corresponding to the limiting portion 14.

[0065] Specifically, through the ingenious cooperation between the avoidance groove 213 and the limiting portion 14, this design realizes the stable connection between the fixing plate 21 and the hard disk frame 1 and the reliable limiting during the sliding process of the hard disk frame 1. The main function of the avoidance groove 213 is to provide guidance and a channel for the installation of the fixing plate 21. During installation, it allows the fixing plate 21 to move along a specific direction to the lower part of the limiting portion 14, reducing the installation difficulty and improving the installation efficiency. While the limiting portion 14 and the limiting plate 11 form a limiting relationship with the fixing plate 21 by their own structures during the sliding process of the hard disk frame 1, restricting the movement range of the fixing plate 21 and preventing it from detaching from the hard disk frame 1, ensuring the structural stability of the entire hard disk plugging and unplugging device during operation, enabling all components to work together, and guaranteeing the accuracy and safety of the hard disk 3 plugging and unplugging operations. This design realizes complex functions with a simple mechanical structure, optimizing the overall performance of the device. When installing the hard disk frame 1, first align the fixing plate 21 with the limiting plate 11 so that the avoidance groove 213 on the fixing plate 21 accurately aligns with the limiting portion 14. Subsequently, push the fixing plate 21 along the direction defined by the avoidance groove 213. Under the guidance of the avoidance groove 213, the fixing plate 21 can smoothly move to the lower part of the limiting portion 14 to complete the preliminary installation positioning. When the hard disk plugging and unplugging device is put into use and the handle 23 is rotated to drive the hard disk frame 1 to slide along the fixing plate 21, the limiting plate 11 and the limiting portion 14 jointly limit the fixing plate 21 from different directions. During the sliding process, the limiting plate 11 and the limiting portion 14 continuously exert a restraining force on the fixing plate 21, keeping it in a predetermined position all the time and preventing it from detaching from the hard disk frame 1, thereby ensuring that the hard disk frame 1 slides smoothly along the established track and ensuring the successful completion of the hard disk 3 plugging and unplugging operations. This design greatly enhances the structural stability and operation reliability of the hard disk plugging and unplugging device. On the one hand, the setting of the avoidance groove 213 simplifies the installation process of the fixing plate 21 and the limiting plate 11, reduces the operation difficulty during installation, and improves the installation efficiency. On the other hand, the limiting portion 14 effectively prevents the fixing plate 21 from detaching from the hard disk frame 1 during use, significantly reducing the shaking and deviation during the sliding process of the hard disk frame 1, ensuring the accuracy of the hard disk 3 plugging and unplugging operations, and reducing the risk of equipment failure caused by unstable structure. In addition, this design also improves the service life and maintenance efficiency of the equipment, provides a solid guarantee for the stable operation of the hard disk 3, and can better meet the requirements for high efficiency and reliability of the hard disk plugging and unplugging device in actual application scenarios.

[0066] See Figures 1 to 6 As shown, the present invention also provides an embodiment of a chassis, including the hard disk plugging and unplugging device as described above, and further including a connecting plate 4, a backplane 5, and a hard disk 3; the connecting plate 4 is provided with a connector 41; the hard disk frame 1 is located between the connecting plate 4 and the backplane 5; the hard disk 3 is installed in the hard disk frame 1 and is plugged into the connector 41; both ends of the fixing plate 21 are detachably connected to the connecting plate 4 and the backplane 5 respectively.

[0067] Specifically, in this embodiment, the hard disk plugging and unplugging device is organically integrated with other components of the chassis, based on the design concept of modularization and convenient maintenance. The connecting plate 4 and the backplane 5 serve as the basic structural components of the chassis, providing a stable installation support for the hard disk plugging and unplugging device to ensure that the fixing plate 21 remains stationary; the connector 41 is used to achieve the electrical connection between the hard disk 3 and the internal circuit of the chassis and is the key hub for data transmission. By installing the hard disk 3 in the hard disk frame 1 and using the hard disk plugging and unplugging device to achieve the plugging and unplugging of the hard disk 3 and the connector 41, the installation, disassembly, and replacement operations of the hard disk 3 in the chassis are made more convenient and efficient, while ensuring the stability and reliability of the connection between the hard disk 3 and the internal circuit of the chassis.

[0068] When installing the hard disk 3, first place the hard disk 3 into the hard disk frame 1 to ensure that the hard disk 3 is stably installed, and then install the handle mechanism 2 on the hard disk frame 1. Then, place the hard disk frame 1 together with the hard disk 3 between the connecting plate 4 and the backplane 5, and through the detachable connection structure at both ends of the fixing plate 21, fixedly connect the fixing plate 21 to the connecting plate 4 and the backplane 5, so that the hard disk plugging and unplugging device is stably installed in the chassis. At this time, rotate the handle 23 to make the handle mechanism 2 change from the open state to the closed state, drive the hard disk frame 1 to slide along the fixing plate 21, and make the hard disk 3 accurately inserted into the connector 41 on the connecting plate 4 to complete the installation process of the hard disk 3. When removing the hard disk 3, rotate the handle 23 in the reverse direction to make the handle mechanism 2 change from the closed state to the open state, the hard disk frame 1 drives the hard disk 3 to be pulled out from the connector 41, then release the connection between the fixing plate 21 and the connecting plate 4 and the backplane 5, and pull the handle 23 outwards to take out the hard disk frame 1 and the hard disk 3 together to achieve the removal of the hard disk 3.

[0069] This design realizes the rapid and convenient installation and disassembly of the hard disk 3 in the chassis, greatly improving the maintenance efficiency of the hard disk 3 and reducing the maintenance cost and time. At the same time, through the organic combination of the hard disk plugging and unplugging device and the chassis structure, the stability of the connection between the hard disk 3 and the internal circuit of the chassis is ensured, reducing the data transmission failure and the risk of hard disk 3 damage caused by unstable connection. In addition, this design also improves the overall performance and maintainability of the chassis, enabling the chassis to better adapt to the needs and application scenarios of different users, enhancing the practicality and competitiveness of the device. In addition, this design also closely associates the connection state of the hard disk 3 with the state of the handle mechanism 2, realizing the visualization of the connection state of the hard disk 3, greatly improving the convenience and accuracy of the operation. Users do not need to rely on additional detection tools, and can quickly and accurately judge whether the hard disk 3 is connected to the chassis only by observing the closed or open state of the handle mechanism 2, reducing the uncertainty and misoperation risk in the operation process and enhancing the user experience.

[0070] See Figures 1 to 6 As shown, in a specific embodiment, the hard disk frame 1 is provided with a notch 15 corresponding to the connector 41.

[0071] Specifically, in this embodiment, a notch 15 is provided at the position of the hard disk frame 1 corresponding to the connector 41. Its design principle is based on providing a direct channel for the connection between the hard disk 3 and the connector 41, reducing the obstruction during the insertion and extraction of the hard disk 3. The notch 15 is provided to make the insertion and extraction of the hard disk 3 into and out of the connector 41 smoother, avoiding inconvenient operation or damage to the hard disk 3 and the connector 41 due to the obstruction of the structure of the hard disk frame 1, thereby improving the efficiency and accuracy of the insertion and extraction of the hard disk 3. When installing the hard disk 3, place the hard disk 3 in the hard disk frame 1. Through the notch 15 on the hard disk frame 1, the hard disk 3 can directly align with the connector 41 on the connection plate 4, and then rotate the handle 23 to drive the hard disk frame 1 to slide, so that the hard disk 3 is smoothly inserted into the connector 41. When it is necessary to remove the hard disk 3, rotate the handle 23 in the reverse direction, the hard disk frame 1 drives the hard disk 3 to be pulled out of the connector 41, and the hard disk 3 is taken out of the hard disk frame 1 through the notch 15. The whole process is simple and direct, reducing unnecessary operation steps and difficulties. This design further improves the convenience of the insertion and extraction operation of the hard disk 3, significantly shortens the installation and removal time of the hard disk 3, and improves work efficiency. At the same time, it reduces the risk of damage to the hard disk 3 and the connector 41 caused by improper operation or structural obstruction during the insertion and extraction of the hard disk 3, improves the reliability and stability of the device, and reduces the device maintenance cost and replacement frequency.

[0072] See Figures 1 to 7 and Figures 11 to 12 As shown, in a specific embodiment, both ends of the fixing plate 21 are connected with connectors 26. The connection plate 4 and the back plate 5 are both provided with insertion holes. The connectors 26 are inserted into the insertion holes. A third elastic member 27 and a reinforcement member 28 connected to the third elastic member 27 are embedded in the connectors 26. One end of the reinforcement member 28 away from the third elastic member 27 abuts against the insertion hole, and the deformation direction of the third elastic member 27 is perpendicular to the insertion direction of the connector 26.

[0073] Specifically, in this embodiment, a third elastic member 27 and a reinforcement member 28 are embedded in the connecting member 26. By utilizing the elastic force of the third elastic member 27 and the abutting action of the reinforcement member 28, a firm connection between the fixing plate 21, the connecting plate 4, and the back plate 5 is achieved. Its design principle is based on the concept of combining elastic buffering and mechanical fastening. When the connecting member 26 is inserted into the insertion hole, the third elastic member 27 pushes the reinforcement member 28 to abut against the inner wall of the insertion hole, forming a tight connection to ensure that the fixing plate 21 is firmly fixed. At the same time, during the insertion and extraction of the hard disk 3, the third elastic member 27 can absorb part of the vibration, reduce the impact of vibration on the hard disk 3 and the chassis, and improve the seismic performance and stability of the device. When installing the fixing plate 21, align the connecting member 26 with the insertion holes on the connecting plate 4 and the back plate 5, and forcefully insert the connecting member 26 into the insertion holes. During the insertion process, the third elastic member 27 is squeezed and undergoes elastic deformation, pushing the reinforcement member 28 to move outward, so that it tightly abuts against the inner wall of the insertion hole, thereby firmly fixing the fixing plate 21 between the connecting plate 4 and the back plate 5. When operating the insertion and extraction of the hard disk 3, rotate the handle 23 to drive the hard disk frame 1 to slide. The vibration generated during this process will be transmitted to the fixing plate 21. The third elastic member 27 absorbs the vibration energy through its own elastic deformation, reduces the transmission of vibration to the hard disk 3 and other components of the chassis, and protects the normal operation of the device. This design improves the connection strength and stability between the fixing plate 21, the connecting plate 4, and the back plate 5, effectively prevents the fixing plate 21 from loosening or falling off during use, and ensures the firm installation of the hard disk insertion and extraction device in the chassis. At the same time, it enhances the seismic performance of the chassis, reduces problems such as component loosening and poor contact caused by vibration, reduces the risk of equipment failure, improves the reliability and service life of the equipment, and is particularly suitable for application scenarios with high requirements for equipment stability and seismic resistance.

[0074] More specifically, the third elastic member 27 is a spring, and the reinforcing member 28 is spherical. Using a spring as the third elastic member 27, its elastic characteristics are utilized to provide adjustable elastic force for the entire connection structure. When the spring is extruded by an external force, it will undergo elastic deformation and store elastic potential energy. When the external force disappears, the spring releases the elastic potential energy and returns to its original state, generating a pushing effect. As a spherical reinforcing member 28, on the one hand, due to its shape characteristics, when it contacts the inner wall of the insertion hole, it can form multiple-point contacts, and compared with planar contacts, it can disperse pressure more evenly, enhancing the stability of the connection. On the other hand, under the action of the spring elastic force, the sphere can flexibly adjust the contact position with the inner wall of the insertion hole to adapt to different force conditions. When the connecting member 26 is inserted into the insertion hole, the spring is compressed, and the generated elastic force pushes the sphere to tightly abut against the inner wall of the insertion hole, thereby firmly fixing the fixing plate 21 between the connecting plate 4 and the back plate 5, ensuring the stable installation of the hard disk plugging device in the chassis. At the same time, during the plugging and unplugging process of the hard disk 3, the elastic deformation of the spring can buffer the vibration generated by the operation. Under the action of the spring, the sphere always maintains close contact with the inner wall of the insertion hole, further reducing the impact of vibration on the device and protecting the hard disk 3 and other components inside the chassis. It can be understood that in other solutions, the third elastic member 27 can also be set as other types of elastic members, and the shape of the reinforcing member 28 can also be set as other solutions according to needs.

[0075] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
